Obito Uchiha

is a chūnin of Konohagakure who was believed to have died during the Third Shinobi World War after his right body was crushed by a boulder, but survived with the help of Madara Uchiha. Distraught by the death of the girl he loved during his teenage years, Obito later became a criminal and dedicated his efforts into working towards a plan to end world conflict, at times using the aliases of, or Madara Uchiha (whom he has inherited his ambitions from). For years, he manipulated Akatsuki from the shadows to achieve his goals before eventually going public with his plans, and declaring a Fourth Shinobi World War.

Early life
Obito grew up not knowing who his parents were, leaving him alone and forced to fend for himself. This sad upbringing led Obito to dream of one day becoming the Hokage so that the people of the village would acknowledge his existence. On the day that he was to enrol at the Academy, Obito had arrived late to the opening ceremony. Believing he was too late, he was relieved when Rin Nohara handed him his orientation-documents. He eventually graduated at the age of 9 and was placed in Team Minato with Rin and Kakashi Hatake under the leadership of Minato Namikaze. For their final test to become genin, Minato tasked his potential students with taking one of two bells from him in actual combat. As Kakashi pointed out that a lack of three bells meant at least one of them would fail, Obito became determined to not be that one, attacking Minato alone. Soon seeing that Minato was far to advanced for them to take alone, Obito agreed to work with his team to get the bells. Ultimately, Minato passed all three of them as they succeeded in the real test: showing team-work. The team took part in the Chūnin Exams, where Obito arrived late for a second round in the Forest of Death having stopped to help an elderly woman. When Team Minato ran across an enemy team, Obito attempted to impress Rin with the Uchiha clan's fire technique, but ended up choking on the candy the elderly woman had given him and was soon defeated by Might Guy. He trained extensively between the second and third round and told Rin his dream of becoming Hokage; however, he was eliminated from the exams in another bout with Guy, who was then beaten by Kakashi, allowing him to rise to the rank of chūnin. Obito did attain the rank some years later at the age of 11.

During the Third Shinobi World War, Kakashi was placed in charge of the team for a mission to destroy the Kannabi Bridge, which would hinder Iwagakure from using Kusagakure as a relief point. Before beginning the mission, Minato and Rin gave gifts to Kakashi to celebrate his promotion to jōnin, though Obito had forgotten thus straining an already poor relationship. Minato would soon be called to the front lines, leaving the team to carry on the mission alone. The three were then discovered by Iwa-nin and Rin was captured. Kakashi elected to abandon Rin, believing it was more important to finish the mission before concerning themselves with her safety. Obito became enraged at the idea and insisted that they focus on her rescue. When Kakashi refused, Obito left on his own, remarking that Kakashi was worse than scum for abandoning his friends.

Obito found the cave the Iwa-nin were using as a hideout, but before he could make much progress, was found and attacked by a camouflaged Taiseki. Kakashi having a change of heart because of Obito's parting words, arrived and saved Obito, shielding him from Taiseki's attack, but damaging his left eye in the process. To save his team-mate, Obito awakened his Sharingan for the first time, allowing him to see through Taiseki's camouflage and kill him. The two found and released Rin from her restraints, prompting Kakkō to bring the cave down around them. As they made their escape, Kakashi's limited vision greatly hindered him, and when Obito noticed he was about to be crushed by a falling boulder in his blind spot, he pushed him out of the way and became trapped under the rubble in his place, crushing the right half of his body. With no way to escape, Obito accepted his fate and made an offering: to give Kakashi his left Sharingan as an apology for forgetting to get him a present earlier.

Rin performed the transplant and once the procedure was finished, Kakashi used his new Sharingan to kill Kakkō. The Iwa reinforcements quickly began to further compress the rubble forcing Kakashi and Rin to leave Obito behind. As the rocks tightened around him, Obito lamented that he had finally became friends with Kakashi and failed he couldn't confess his feelings for Rin.

Afterwards, Minato rescued Kakashi and Rin and Obito was believed dead, his name marked in Konoha's memorial.

However in actuality, Obito was rescued by an elderly Madara Uchiha who found the younger Uchiha when the cave-in brought him to one of his tunnels leading to the Mountains' Graveyard. Though his Sharingan was miraculously unharmed, the entire right side of his body from the neck down was completely destroyed, prompting Madara to reconstruct half of his body using parts of Hashirama's living clone. Telling Obito that he now owes him his life, Obito instead declared he wanted to return to Konoha and be with his friends. Madara informed him that his new body would prevent him from becoming a shinobi again, and that in the end it wouldn't matter. Madara preached about the harsh nature of reality and how he has a plan to change the world. Still unconvinced, but otherwise unable to leave, Obito remained in the Mountain Graveyard to recuperate. During his recuperation, he met and became friends with White Zetsu and one of his many clone brothers while undergoing rehabilitation in order to use his new limbs.

As Obito was finally getting used to his new limbs, White Zetsu alerted him to the fact that Kakashi and Rin were surrounded by Kirigakure-nin and in danger. Obito tried to punch through the wall blocking the Mountain Graveyard, but ended up destroying his right arm and barely breaking the wall. Guruguru, wanting to help and sure Madara would allow it, encased Obito with his body which gave him the strength to break the wall. As Obito prepared to leave, he told Madara he had no intention of returning, but thanked him for saving his life. Madara in turn told him that he will return willingly and thank him truthfully. Using Guruguru to locate his friends, he learned that Minato was once again absent.

On his way, Obito's left eye socket caught a glimpse of what his left eye was actually seeing, but dismissed it as a panic thought. Upon reaching the battlefield, he was shocked to see Kakashi had impaled Rin through with his Chidori.

As Rin died before both of them, their Sharingan matured into the Mangekyō Sharingan and Kakashi passed out quickly afterwards. The Kiri-nin attempted to claim Rin's body for intel.

Enraged by this, Obito, experiencing a surge of rage and grief responded by using a combination of his Kamui ability and Wood Release sprouting from his body which resulted in the deaths of all the Kiri-nin and ignoring Kakashi completely, Obito cradled Rin's lifeless body and, with Madara's words still echoing in his mind, vowed that he would create a world where they could be together again.

Moving the Plan Forward
With new conviction, he returned to Mountains' Graveyard, and agreed with Madara's conclusion that the reality they lived in was worthless and should be destroyed. He vowed he would create a new reality where he, Rin, and Kakashi would be together again. Pleased, Madara told Obito the details of the Eye of the Moon Plan, the secrets of the Demonic Statue of the Outer Path, and the role Nagato would play with his Rinnegan. He would go on to teach Obito much of his skills and knowledge; this included various kinjutsu, advanced Uchiha techniques, the Yin–Yang Release, and the power of the Rinnegan. Before passing, Madara also created Black Zetsu by pouring his will into White Zetsu and also left part of his will in the chakra receiver which extends from the statue's navel. Disconnecting himself from the Demonic Statue, Madara told Obito that until the day he was revived, he would be Madara Uchiha and must work to bring the Eye of the Moon Plan to completion.

Obito and Zetsu travelled to Amegakure to meet the Ame Orphans, who were sceptical at Obito's claim that he was Madara and his plan to make a world where everyone wins despite Nagato wanting to know about his powers. Yahiko brushed Obito off and told him to stay away from them. Obito, however, stated that he would return to that spot everyday until they understood and came to him willingly. Eventually, after the death of Yahiko, Nagato would become Pain and join Obito, this beginning the current incarnation of Akatsuki. In the anime, Obito watch from the sidelines as Akatsuki would continue their idealistic pursuit of peace while Danzō Shimura would disrupt peace agreements between Konoha and Iwa in his own pursuit of strengthening Konoha. When Danzō decided to frame Akatsuki for the death of several Ame ninja, making Hanzō see them as a threat to his power tricked Yahiko into meeting him for an alliance, Obito saw this as the perfect opportunity to win over Nagato. As the other members of Akatsuki learned of the Konoha ANBU's involvement they rushed to their leader's aid, only to be intercepted by Obito and Zetsu and quickly dispose of them. Obito and Zetsu then watched as Hanzō completed his plan to kill Yahiko, to which Obito witnessed Yahiko's death mirroring Rin's. With Nagato's personal beliefs destroyed, he finally joined with Obito, to which Konan followed.

From this point, Obito's actions are largely unknown. As Tsunade speculated years later, the reason Obito adopted his name was to take advantage of the power it invoke in peoples' fears of the legend himself. Because of the many infamous acts Madara carried out during his lifetime (such as acquiring an Eternal Mangekyō Sharingan), few are surprised that Madara could still be alive after such a long time. They take the crimes that Obito commits under Madara's name as further confirmation that he is really Madara, as only Madara would be capable of such deeds. Obito also possesses knowledge of things that only the real Madara would know, further giving him credence.

Twelve years before the start of the series, having infiltrated Konoha, Obito learned that Kushina Uzumaki, the Nine-Tails' jinchūriki and Minato's wife, would be giving birth. Obito knew that this would cause the seal keeping Nine-Tails contained within her to weaken. Intending to use the Nine-Tails, Obito tracked her down and took the newborn Naruto Uzumaki hostage to keep Minato from interfering. Once he extracted the beast, Obito placed the tailed beast under his control and ordered it to destroy Konoha. Using Kamui to keep Minato from going to the village's defence, keeping his true identity hidden while reaffirming his ambitions, Obito engaged Minato before being hit by a Rasengan and branded with Minato's Flying Thunder God Technique, to which Obito didn't know would never disappear. Wounded with Minato's Contract Seal disrupting his control over the Nine-Tails, Obito fled while vowing to regain the tailed beast, and declared that he still had other plans.

Eight years after the Nine-Tails' attack, the Uchiha clan who had been ostracised and placed under heavy suspicion for the attack as the full story of the event died with Minato and his wife, Obito infiltrated Konoha to rekindle the flames of war. He was found by Itachi Uchiha first, who thought he was Madara and convinced Obito to spare the village in exchange for helping to wipe out the Uchiha clan, to which he complied. Afterwards, Obito offered Itachi a place in Akatsuki, which he accepted. Around that time, Obito also met with Danzō Shimura for unknown reasons. At some point in time, Obito also took control of the Fourth Mizukage, in effect making him the "real" Mizukage of Kirigakure. Kisame Hoshigaki was one of the few Kirigakure ninja to know of his manipulation of the Fourth yet helped Obito in his quest to bring about an end to the "world of lies". Later on, Obito abandoned his name, calling himself Tobi in order to join the Akatsuki as Zetsu's subordinate to establish and hide himself among their ranks before finally putting Madara's plan into motion.

Personality
In his youth, Obito was constantly late, which, more often than not, was due to the good deeds he had stopped to do, such as aiding the elderly. Having made it a point in his life to do so, he noted that he knew all the elderly persons in Konoha, stopped once on his way to the Chūnin Exams to help an elderly woman carry her luggage, and even comically offered to clean Madara's nether regions when he met him. Obito was also easily moved to tears, which he always insisted was because he had gotten something in his eyes despite wearing goggles. Obito was in love with Rin; but his feelings were not reciprocated as Rin was attracted to Kakashi instead. Frustrated by this, Obito envied Kakashi's prodigious skills, and so constantly sought to surpass him. Although these efforts usually ended in failure, he was able to spend time with Rin while she treated his injuries. Ultimately, Obito would never get the chance to reveal his feelings to Rin before his "death". As Kakashi noted, besides his student's rivalry with Sasuke and one-sided feelings for a female peer, Naruto shared other beliefs Obito had, such as his desire to become Hokage and never abandoning comrades on the battlefield. Even after "dying", Obito still cared deeply for his friends and village, and immediately wanted to return to see them again. However, upon witnessing Rin's death at the hands of Kakashi, Obito's determination and idealism were destroyed beyond any hope of repair, and as a result his personality forever changed.

By the time he reached adulthood, conditioned by Madara to continue his work, Obito's personality changed drastically as he became extremely focused, calm, and serious. From his former loyalty and ideologies that seems to be derived from the Will of Fire, he had succumbed to his clan's Curse of Hatred with the entire world itself as the object of his loathing and the shinobi system that led to Rin's senseless death being what made him lose hope in it. This conviction became increasingly stronger to the point of Obito no longer caring for his well being, stating that he was nobody and that nothing in this world matters to him besides the Eye of the Moon Plan. This lack of empathy includes those close to him, attacking Minato and Kakashi without hesitation, not caring if he ended up killing them as he believes once the Eye of the Moon Plan is completed, he can just revive them along with Rin. Only Obito's love for Rin remained, his desire to create a peaceful world where she would exist together with him happily becoming the motivation for his actions, a determination that proved strong enough for him to resist the Ten-Tails' corruption of his consciousness and allowed him to assume control of its vast powers. He also became friends with Zetsu prior to his personality change, being one of his few (if not only) genuinely positive relationships that he maintained in his adulthood.

In the anime, despite his newly developed mindset, Obito is shown somewhat saddened witnessing Nagato and Konan's loss of their friend Yahiko (which reminded him of Rin's death), silently telling the two Ame orphans they would reunite with their friend again in the dream world without fail. Obito also offered Itachi a place to belong in the Akatsuki after realizing he would have no place to go after they massacred their own clan even though he knew full well Itachi would end up spying on the Akatsuki.

Despite Madara being the one who saved his life and gave him purpose of the plan, Obito later disregarded his gratitude and openly stated to Madara that he doesn't truly consider him an ally. He also took advantage of his own necessity in Madara's ultimate ambition of becoming the Ten-Tails' jinchūriki in order to plunge the Allied Shinobi Forces into despair. In truth, Obito never intended for Madara to become the Ten-Tails' host, instead desiring to be the vessel of the beast himself.

While frequently arrogant about his own abilities and disrespectful of those he considers as weak, Obito is not above giving praise to his enemies, such as his former teacher Minato for being able to wound him and Kakashi for his speed. He also appreciated Itachi Uchiha, saying that Itachi never ceased to amaze him, and that if he had not kept some secrets from Itachi, Obito would have died from the latter's last trap. He had also forsaken his dream of being Hokage and ideals of camaraderie, and derided Naruto for having both qualities. His own disdain for his former dreams and belittlement of the morals of his opponents was extended towards his former compatriot Kakashi, berating him not to open his mouth so easily, Guy for always forgetting people's faces, as well as Minato for always being late during times of crisis. While Obito's words are often painfully striking, they often hold much truth - he seems to enjoy debating with the enemy, severely shaking down Naruto's determination after Neji's death, citing that Naruto has lost many people, and that his beliefs would only lead to the deaths of all who had acknowledged him; Madara noted that Obito had become like his own past self.

Although Obito does not blame Kakashi for Rin's death, he considers him trash like himself and anyone who has lived in the world for so long, a twist to his former belief that anyone who abandons their comrades are lower than trash; he nevertheless seemed infuriated when Kakashi mentioned Rin, and responded viciously. Obito has also taken up an aggressive and sadistic disposition, taking the newborn Naruto hostage to release Kurama from his mother and mercilessly killing Torune in order to be reincarnated moments later by using Fū as a sacrifice, all for the purpose of testing Kabuto's abilities.

When first introduced as "Tobi", Obito exaggerated his former personality to ridiculous extremes, acting the role of the happy-go-lucky idiot who annoyed most members of the Akatsuki, particularly Deidara, who frequently attacked Obito in a comedic fashion. Kisame, on the other hand, appreciated Obito's ability to brighten up a gloomy organisation such as theirs. In the anime, Obito was shown keeping up this charade even when no one was around. Eventually, Obito discarded his role as a fool after Deidara's death and used it one final time to distract the Eight Man Squad during Sasuke's battle with Itachi before finally revealing his true self as Naruto and the others struggle to come to terms with the news.

Obito is a master manipulator, either by subtly corrupting his target's own goals, omitting parts of stories or events to his own benefit as he did with Sasuke, or by appearing to share their beliefs. This is best seen in the existence of the Akatsuki, its wildly-differing members working together because they believe the organisation furthers their own ends; in actuality they are mere tools that further Obito's agenda, as noted with the case of Nagato. He often avoids responsibility for the influence he has over others, claiming those he coerced and manipulated had followed him willingly. He is also capable of great patience in attaining his goals, even lecturing Sasuke on it at one time. However, his patience isn't unlimited — at one point he chooses to discard caution and proceed with his plan in a more aggressive and decisive manner, and when the Ten-Tails is revived, he insists that the Eye of the Moon ritual be commenced immediately. He is also prone to taking risks — revealing Itachi's true history and motives with Sasuke to win his services was the first of many gambles Obito takes. Even though Sasuke did not always live up to his expectations, such as being unable to defeat the five Kage, Obito was nevertheless happy with his "development": his developing Sharingan and his growing isolation from all other allies. While he had threatened to kill Sasuke at times and even offered to turn him over to others, Obito remained attached to Sasuke, at least until he no longer had use for him. Indeed, when Obito and Sasuke were reunited on the battlefield, the former had attempted to kill the young Uchiha and his allies multiple times after becoming the jinchūriki of the Ten-Tails, enforcing the fact that Obito and Sasuke's past relationship was based on mutual gain alone.

Obito has also recently acquired somewhat of a fixation on Naruto Uzumaki, who reminds him of himself in his youth. Because of the similarities between Naruto and himself as a child, Obito expresses great anger towards Naruto for continuing to follow the same ideology that he once possessed until Rin's death, considering him incredibly naive and childish to still believe in such principles. Nonetheless, the Uchiha displayed confidence that Naruto would one day end up like him, and nearly succeeded in proving this point after having the Ten-Tails kill his comrades right before his eyes. However, when this ploy failed to change Naruto's way of thinking thanks to Hinata and Kurama's interference, Obito became rash and careless, accidentally allowing the Ten-Tails to be injured by Killer B after impulsively trying to use its power to kill more of Naruto's allies. When Obito later questioned Naruto why he was exhausting himself to protect his friends if their deaths brought him closer to them, the young ninja's response that having no comrades at all was far more painful than losing them seemed to provoke a slight reaction from the Uchiha. Obito would later reveal to Kakashi, who believed his former friend was using Naruto as some kind of guinea pig, that his intentions with testing Naruto's morals were so that he could asperse everything Naruto believes in, the same ethics he himself once believed in as well. However, the more Naruto repudiated his nihilistic perspective, the more frustrated Obito became.

Kakashi would later deduce the reason for this, noting that Obito's Will of Fire had never actually burned out, and that his actions and unwillingness to acknowledge this are causing him inner turmoil that was tearing him up inside. Indeed, as he clashes with Naruto and Sasuke, Obito briefly envisioned the way his life would have turned out if he had returned to Konoha when Rin died, rejoined his comrades, and even going so far as to imagine himself as Hokage, despite not consciously understanding why. Upon seeing such visions again, Obito would start to conclude that he is subconsciously regretting his actions affiliated with the Eye of the Moon Plan. Despite this, he has consciously convinced himself into not regretting his actions in the slightest just so long as he can bring the Eye of the Moon Plan to fruition.

In the end, however, Naruto's actions succeeded in changing Obito's mindset, allowing Obito to finally overcome his Curse of Hatred. The Uchiha finally understood why Naruto was succeeding while he himself failed after Kakashi explained the reason to him. As a result, Obito openly expressed regret for what he did. Rather than take the "easy" path of dedicating his life to making up for his actions, he chose instead to redeem himself by walking in the footsteps of Nagato and offering his own life to revive all the people he and Madara killed during the war, solemnly telling Kakashi that he was unworthy of seeing Rin in the afterlife. Despite this negativity, Obito's identity tempted to remind him of why he became Tobi in the first place, but Obito compared Madara's former words to Naruto's, and Obito assured Madara that he was not him, but rather Obito Uchiha, the current him that wanted to become Hokage. From there, Minato and Kakashi were convinced that Obito had returned to his former self, and with Kakashi's help, Obito ultimately sealed Yin Kurama into Naruto and saved his life.

Appearance
As a child, Obito had short, spiky, black hair and black eyes. He wore a long sleeved blue uniform with metal plating on the part that reached the back of his hands, as well as a blue jacket with an orange collar and trimmings. The jacket was fastened to the rest of the outfit by two buttons on the collar, and has the Uchiha clan crest at the back. He also wore a white belt, shinobi sandals, the standard Konoha dark blue forehead protector, and a pair of goggles with orange lens connected to ear protectors. After he was retrieved from Kusagakure, Madara replaced his destroyed right side with artificial substance from Hashirama's living clone. The right side of his face still remains heavily scarred in a manner similar to deeply-aged wrinkles. During his rehabilitation, Obito grew his hair out, with the shape similar to that of Madara's. He eventually cut it back down to the short length as in his childhood. During the Nine-Tails' attack he wore a long hooded black cloak and a yellow-orange mask with a pattern that resembled his facial scar, some time before the Nine-Tails' attack on Konoha. During his meetings with Kisame, and Itachi respectively, Obito was seen with long hair yet again, but he later cut it back to its usual length which he wears to this day, he also wore Uchiha robes with a sash on his waist and a yellow-orange mask that had a black flame pattern, that resembled Amaterasu's flame. During his meeting with Kisame, he wore a dark blue kimono and with most of limbs, including his entire chest and stomach heavily wrapped in gauze; the only exceptions are his lack of gauze on his right arm and hand.

As an adult, under the name "Tobi", Obito created an orange mask with spiral-pattern that only shows his right eye, a reminiscence of when Guruguru encased him. Under his Akatsuki cloak, he wears a black long-sleeve top that also covers his neck and chin, a pair of black gloves, and a pair of dark-coloured pants along with the standard Akatsuki shoes and white stirrups. On his waist, he wears a thick black belt with armour-like metal plates attached to it. He wore the same metal plates on his shoulders with a green scarf before becoming Deidara's partner. He wore blue nail polish on his fingers and toes (black in the manga). As Tobi, he wore dark grey (black in the manga) gloves and Sasori's ring on his left thumb.

After he acquired the Rinnegan, Obito started wearing a new mask made of strong materials suited for the looming Fourth Shinobi World War. The mask was white with a purple tint that covers the entire upper-half of Obito's head with a design that resembled the Ten-Tails' eye, consisting of a ripple-pattern with three tomoe around the centre; two of these tomoe acted as the mask's eye-holes. He noted to Naruto that this new mask had been specifically designed for combat, making it very durable. He also dons the Uchiha clan's traditional clothing during the Warring States Period. This attire includes a pair of black pants and gloves, with a white, presumed form-fitting shirt (black in the anime prior to episode 325) underneath. Over this he wears a purple, high-collared, long sleeve mantle that splits down the lower half and has the Uchiha crest on the back. Around his waist he wears a simple, light-purple obi and a belt. Strapped to his back, he carried a purple gunbai with black trimmings and black tomoe, connected to a black chain that ran up his right sleeve. During his first meeting with Madara Uchiha during the Ten-Tails Revival Arc, he removed the chain attached to the gunbai and handed the fan back to Madara.

After being forced to use the Outer Path: Samsara of Heavenly Life Technique, Obito's hair turned white and the right half of his body turned completely black due to the influence of Madara's will, his appearance resembling Zetsu. Immediately after becoming the Ten-Tails' jinchūriki, Obito's body undergoes a drastic transformation. He still possesses white hair, his skin turns white; and his Sharingan and Rinnegan in addition to ten protrusions coming from his back, five near his shoulder and five near his hips, as well as a black assortment of ten magatama on his back; one large one, with a black Rinnegan-like pattern within it, on his mid-back, and nine smaller ones, arranged in rows of three, below it. In addition, the entire right half of his body has acquired a unique black, scale-like pattern across it, replacing the scars he acquired as a child, including repairing all the wounds inflicted on him during the Fourth Shinobi World War. When Obito managed to regain control of the Ten-Tails, he undergoes yet another transformation. In this new form, the ten protrusions on his back now form the collar and coattails of a haori. Two horns also sprout from his forehead; the left smaller than the right. Additionally, he gains six magatama markings across his chest.

Abilities
While a member of the Uchiha clan and becoming a chūnin at the age of 11, Obito's overall prowess as a shinobi was average at best, constantly behind his other classmates. In spite of this relatively slow development in his younger years, Obito's talent began to surface after awakening his Sharingan, able to quickly adapt and use advanced techniques as well as easily take down a group of jōnin and ANBU, proving to be a late bloomer. Guruguru noted Obito's potential as the reason why Madara Uchiha had chosen him as his disciple. As an adult, trained by Madara, Obito became an extremely powerful shinobi with his abilities being a near-mirror image of Madara's own which, in conjunction with his masked persona, led several top-level shinobi to assume Obito was the legendary Uchiha due to his remarkably high level of skills and prowess. As such, Obito has been able to hold his own against multiple Kage-level and S-rank shinobi, as well as perfect jinchūriki on numerous occasions. In spite of all this, Obito generally avoids direct combat, unless absolutely necessary and will instead manipulate others to fight for him.

Taijutsu
As a child, Obito was fairly skilled with taijutsu, though not at the same level as Kakashi or Might Guy. After awakening his Sharingan, he became able to read and predict his opponents movements, able to effectively counter attacks from Kakkō, an experienced Iwa-nin. He also displayed skill in coordinated attacks alongside Kakashi using his Sharingan. Later on, his skill showed noticeable growth, able to subdue various elite Kiri-nin he fought after Rin's death. In his adulthood, Obito was able to fight against two of Danzō's most skilled ninja in Root simultaneously and defeat them, as well as go up against his former friend Kakashi, a taijutsu expert. He mostly achieves this by using his hand-to-hand combat in tandem with his Sharingan and space-time technique to allow opponents to phase through him and then quickly counter using the elements of surprise and confusion.

He also displayed great physical strength as seen when he threw Kakashi to save his life. Due to his artificial body, Obito's physical strength was increased significantly, able to crack a massive boulder shortly after his rehabilitation, strangle a ninja to death, stop a slash from Kubikiribōchō's slash without injuring himself, and hold Konan off the ground by her throat, each while using only one hand. Obito has also developed a near-complete immunity to pain, enough to emerge almost unfazed from sustaining massive damage from Konan's mass of exploding tags. He also survived being impaled through the chest with a lightning-infused kunai by Kakashi and on top of that being slashed across the chest by Minato shortly after.

Obito has displayed a high level of speed. His quick reflexes and reaction time could get rid of a trap sprung on his team. During his encounter with Kakkō, his effectively intercepted the Iwa-nin's attacks, creating an opening for Kakashi to attack. He also displayed speed against the Kirigakure ninja he fought, closing distances quickly and landing a series of swift blows and punches before any of them could react. As an adult, Obito's agility was great enough that he was able to keep up with Naruto in his Nine-Tails Chakra Mode.

Nature Transformation
As a recognised member of the Uchiha clan, Obito is well-versed in Fire Release techniques, which he was able to use quickly, as seen during a mission where he demonstrated in a fast use of the Fire Release: Great Fireball Technique. In the anime, Obito displayed the ability to conceal shuriken in multiple small fireballs. As an adult, his Fire Release prowess developed greatly, with his techniques being of the same size and scale of that of his teacher, Madara Uchiha, the strongest Uchiha in history. He can use his space—time techniques to enhance his Fire Release techniques to increase its already considerable range, such as the Blast Wave Wild Dance technique.

Obito gained the ability to use Wood Release after acquiring artificial limbs created from Hashirama Senju's cells. His skill with this kekkei genkai was shown during his assault on several Kirigakure-nin after Rin's death. He could use the Wood Release: Cutting Technique to produce wood projectiles which multiplied inside a victim's body once stabbed by them. He can also produce massive tangled roots from ground to viciously crushed his enemies or smaller roots from one of his arms to restrain and constrict his opponents. Using Hashirama's cells, Obito could connect and control (albeit with difficulty) a tailed beast as powerful as the Ten-Tails. Aside from the Wood Release, Obito can presumably use its two component elements: earth and water. He has shown an aptitude with the former element as seen when he burrowed and moved underground to spread bombs across a battlefield to create a literal minefield and also to create various holes and move quickly through for sneak attacks.

Bukijutsu
As an adult, Obito has been shown wielding various weapons. During the Fourth Shinobi World War he began carrying the signature war fan of Madara Uchiha. He has used it in a similar fashion to a flail attached to a chain, and a means of defending. With this weapon, he was able to hold his own against Naruto in his Nine-Tails Chakra Mode and Might Guy, a taijutsu master in conjunction. In his first fight with Minato Namikaze, he used a long chain attached to braces on his wrist, resembling shackles in conjunction with his intangibility, harmlessly passing through his opponents before solidifying to restraining them with the trailing chain. Obito also a one point carried a sword at his waist implying he is versed in kenjutsu, having performed such skill with makeshift tools like a simple pipe to impale Konan, and in the anime skilfully block a flurry of her Paper Shuriken.

After implanting Madara's left Rinnegan from Nagato, Obito displayed a wide use of the chakra receivers. By implanting a single chakra receiver within former jinchūriki, Obito was able to control and manipulate them entirely as well as force them to adopt their jinchūriki transformations at will. He also has giant stakes, used to stab enemies and produce chakra chains that can restrain a tailed beast. During his battle against Kakashi, Obito also used the blade version of these rods, producing one from the palm of his hand.

Once becoming the jinchūriki of the Shinju and gaining complete control of the beast, Obito gained access to the Sword of Nunoboko, the very blade that Hagoromo Ōtsutsuki once wielded, and said to have formed the world with. The blade is formed out of the Shinju's Truth-Seeking Balls, and Obito claimed he can use it to lay waste to the world.

Shurikenjutsu
As an Uchiha, Obito is proficient in the use of shuriken techniques and wields a set of giant shuriken of varying sizes (from the size of handheld ones, to ones larger than a full-grown person) stored in the other dimension, which he can instantly bring out, by using his Kamui's spiraling distortion to launch them at a high rotational speed, which adds an element of surprise to the attack and gives the opponent minimal time to react accordingly. He also uses them as close-range melee weapons against Kakashi, for both stabbing and slashing. He also has a set of giant kunai, which he uses in an identical fashion in conjunction with his dōjutsu.

Sharingan
When Obito first awakened his Sharingan it already had two tomoe and he was able to take immediate advantage of it despite his inexperience. His eye gained three tomoe after witnessing Rin's death. After giving up his original left eye to Kakashi, Obito obtained a new left Sharingan eye and has multiple Sharingan placed in storage should he need them. As an adult, Obito seems to be able to keep his Sharingan active for extended periods of time with little drain on his chakra levels. He can use his Sharingan to place individuals under genjutsu from a single moment of eye-contact and then perform effects like force his victims to reveal information or incapacitate them, and trapped both Fū and Torune in a genjutsu for a considerable amount of time. He also battled his former friend Kakashi, another skilled Sharingan user in a genjutsu duel to a standstill.

Like Madara, Obito can use his Sharingan to place tailed beasts under his control. Following this, Obito is also able to summon the controlled beast at any time, as he did with Kurama, the Nine-Tailed Demon Fox, to attack Konohagakure. While this control can be complete when used on a single target, when cast on multiple ones, it becomes increasingly difficult to maintain said control, allowing the beasts to temporarily break free in certain instances. Obito can also perform a kinjutsu of the Uchiha clan, Izanagi, which allows the user manipulate evens around him into an illusion at the cost of blindness in the used eye after it has exceeded its time limit. While the limits on using Izanagi is very short, Obito used Hashirama's DNA to extend the length of his Izanagi to ten minutes before losing only his replacement left eye.

Mangekyō Sharingan
Obito awakened his Mangekyō Sharingan after witnessing Rin's death at the hands of Kakashi. As naturally a matching pair Obito's eye has has the same design as Kakashi's; three stretched triangles evenly spaced around the pupil that each curve at the top around the eye to form a circle, making it similar to a pinwheel. Uniquely and for unknown reasons, Obito does not appear to suffer from the Mangekyō-induced blindness, nor any signs of exhaustion and physical straining despite his extensive use of its power for years throughout the years. His teachings under Madara have given Obito extensive knowledge of the various Mangekyō techniques. He is also able to somehow disperse the flames of Amaterasu even if engulfed by them.

It is through this dōjutsu that he is able to perform his space-time ninjutsu, Kamui, that is noted by Minato Namikaze to be more versatile than his own and Tobirama Senju's. Kamui serves as a gateway to another dimensional space, which he can instantly send parts of his body or his entirety to and back from, granting Obito two distinct abilities: teleportation, and another best described as "intangibility". When going "intangible" by shifting parts of his being between dimensions, he can allow any matter in the original dimension to harmlessly pass right through him, granting Obito a very effective defense maneuver to escape damage or catch his opponents off-guard. This became such a key element in Obito's fighting style that he rarely resorts to more traditional forms of ninjutsu. He can also extend this intangibility to whatever he's touching at the time. The second part of Obito's Kamui, after shifting to the other dimension entirely, is to travel long distances within relatively short time-spans. He can also teleport any target making physical contact with them, during which a swirling void is form that forcibly sucks the target in. When being transported in this way, the target appears to be sucked into his right eye. The chakra signatures of those in the other dimension completely vanish while in it.

Alternatively, Obito can combine his fire techniques with the spiral distortion generated by Kamui to increase the potency of his attack. He can also use his Kamui to unleash various weapons from the eye's pocket dimension, using the warping distortion to greatly increased their launch speed and force. As versatile as Kamui is, it has some drawbacks. He can only make himself continuously intangible for about five minutes. Because these two abilities are connected to the same technique, Obito can only use one of them at a time; he must remain solid while this teleportation is used, leaving him susceptible to counter-attack when he does so, and it takes longer to teleport himself than it does someone or something else. The only reliable counter to this technique is another person using Kamui against Obito as objects and people warped away by Kamui are sent to the same dimension where can then harm the part of Obito that may exist there at the same time. However, at the same time, Obito is "immune" in a sense to others using this technique on him. Obito later noticed that after becoming the Ten-Tails' jinchūriki, he could no longer "travel through dimensions".

Rinnegan
Following the loss of his left Sharingan due to his use of Izanagi, Obito implanted Madara's Rinnegan, taken from Nagato's corpse, into his left eye socket in preparation for the Fourth Shinobi World War. With the Rinnegan, Obito gains a series of abilities, such as the ability to see chakra, the potential to master all five forms of nature transformation and the ability to summon the Demonic Statue of the Outer Path.

Also as a wielder of the Rinnegan, Obito can access the Six Paths Technique, a series of unique ninjutsu skills. He can use the Human Path technique to extract information from an individual, though the process would kill the target. He has also displayed extensive use of the Outer Path ability, where by combining it with the Demonic Statue, he was able to reseal the tailed beasts into their respective jinchūriki and use their powers freely as well as create chakra chains that he used to suppress their power. Obito is able to use the chains to drag the beasts he controls to reseal them instantly inside the Statue. He can use the Outer Path: Samsara of Heavenly Life Technique which can revive an individual at the cost of his own life, which he noted to be key to reviving Madara as a living individual and not a reincarnated body. Like other users of the Outer Path, Obito can manifest chakra receivers out of the palm of his hand.

Obito makes use of the Six Paths of Pain, with his particular Paths being chosen from the reincarnated jinchūriki, embedding chakra receivers in their bodies which allows him to manipulate them. Each one also has the same eyes as he does (a right Sharingan and a left Rinnegan), allowing him to see what they see and coordinate their movements. This enhances the jinchūriki's original abilities, allowing them to perform a series of collaborative and precise attacks. However, due to the immense chakra consumption that is required, he does not have the Paths use the individual skills granted by the Six Paths Technique.

Body Modifications
After being found by Madara Uchiha, Obito had the right side of his body, which had been crushed by the boulder, artificially reconstructed using the same material as that of White Zetsu and its many clones. Obito's artificial body enables him to replace dismembered limbs on several occasions. During his fight against Minato, after being hit with a Rasengan, his left hand almost split from his arm, while damage looked similar to how his artificial right arm behaves after being hit. Uniquely, Obito's body oozes a white substance instead of blood.

Due to his body being rebuilt by Hashirama's DNA, his physical strength and durability were greatly magnified. This artificial body also possess noticeable regenerative capabilities, as Obito's arm and shoulder was able to repair itself from the damage caused by Naruto's Rasengan within minutes. After becoming a jinchūriki, Obito's regenerative power seems to have grown, as he was able to heal almost instantly from the damage caused by a wind-enhanced Amaterasu attack, as well after having been struck by a senjutsu-empowered Rasengan, which had managed to bypass his defences. His artificial body parts also enables Obito to survive without the need for food or water, but can still enjoy the sensation of eating as seen in the anime. Due to the presence of Hashirama's DNA in his body, Obito gained the Wood Release kekkei genkai.

Due to these augmentations, Obito also gained an immense increase in vitality and chakra reserves as a result, allowing him to achieve various chakra-consuming feats. Such include his constant use of his Mangekyō Sharingan, with no side effects to his chakra or health, even when used in conjunction with other techniques, allowing such techniques to become regular and signature moves for him in battle. His robust reservoir also allows him to summon large and very powerful creatures such as Kurama, items such as the Demonic Statue of the Outer Path,   as well as provide him with the basis required to control five fully transformed jinchūriki at once.

Intelligence
As an adult, Obito is an observant and sharp thinker, capable of reading through deception. He can formulate complicated plans well in advance and accurately predict how others will act in a given set of circumstances. Even on the rare occasions where Obito is caught off-guard he is capable of creating counter-strategies while maintaining a calm and composed demeanour. He is flexible when the situation calls for it, using alternate means to achieve his objective when his original plan fails. His mental endurance is also noteworthy, as he was able to break free from Ino's Mind Body Switch Technique within mere seconds, resist Madara's mental control, and even overpower the Ten-Tails' mind.

Due to Madara's tutelage, Obito gained a vast knowledge of the ninja world, which allows him to almost immediately identify most forms of ninjutsu and counter them if necessary. His knowledge extends far enough back through history that he knows of the existence and secrets of the Sage of the Six Paths.

Obito, in his adulthood, is also shown as a master of manipulation and psychological warfare, being able to exploit an individual's beliefs and convictions into serving his purposes through direct or indirect manners, including skilfully lacing elements of truth in his lies, to deceive people as he did to Nagato, Kisame and Sasuke. He is a skilled actor, having been able to shift away all suspicion and attention with his happy-go-lucky persona of "Tobi", or use an extremely believable performance of Madara himself, even mimicking the legendary Uchiha's voice and speech patterns, to fool those who knew Madara personally like Ōnoki. Obito is also has a great understanding of the politics and machinations of the shinobi world. According to Mifune, he was able to read the signs of the time and use the stability and suspicion between other countries to increase his own power. He was able to fully assume the identity of Madara Uchiha to manipulate the entire shinobi world into a war due to their fear of the legendary Uchiha's abilities. When questioned about why he was going about things in such a roundabout manner by Ōnoki — someone who had witnessed his power first hand — he noted that the fight between "himself" and Hashirama, had left him a shell of his former self. In battle, his efforts are geared into breaking an enemy both mentally and emotionally.

Jinchūriki Transformations
Immediately after becoming the Ten-Tails' jinchūriki, Obito's body undergoes a drastic transformation. His skin colour changes to white; the skin on the entire right side of his body becomes scaly, on his back, ten protrusions appear (five on the upper body and five near his hips) as well as a black unique pattern of magatama on his back; one large one, with a black Rinnegan-like pattern within it, on his mid-back, and nine smaller ones, arranged in rows of three, below it.

In this new, empowered form, Hashirama Senju and Hiruzen Sarutobi themselves, two men with the title God of Shinobi, remarked gravely that Obito was more powerful than even they are. With these new powers, he is able to easily overwhelm four Kage-level opponents working in conjunction with each other without effort nor difficulty. Even Madara noted that at this point, his apprentice had become the same as the Sage of the Six Paths. Both Killer B and Gyūki also noted that Obito is stronger than the Ten-Tails itself while using this form, due to its power being more focused in his human body. Upon completing the transformation, it apparently healed all of Obito's previous wounds, and even the Flying Thunder God Technique's formula mark placed on his back, which shouldn't disappear, disappeared. However, as the new jinchūriki, Obito did not have complete control of the Ten-Tails, characterised by a loss of intelligence and his body becoming distorted and severely bloated at one point.

He gains a dramatic boost in speed, able to destroy large portions of Hashirama's wood clone and the reincarnated Tobirama in an instant, and was even able to land a surprise attack on his former teacher, a man renowned for his quickness. He could also react and contemptuously block Amaterasu despite the technique's sheer speed. His strength has became great enough to demolish an Eternal Mangekyō Sharingan Susanoo ribcage with nothing more than brute force. Likewise, his durability is also increased, emerging unharmed from Tobirama Senju's set of chain explosions. He can create chakra arms, which are capable of breaking even Hashirama's Sage Art: Gate of the Great God and the barrier erected by the four Hokage.

In this form, Obito could create Truth-Seeking Balls from the palms of his hands which can be shaped and formed into shields, lances and spinning blades, as well as being launched against enemies and briefly expand to a massive size to form what can be considered to be a powerful explosion. According to Hiruzen Sarutobi, these spheres are similar in nature to Dust Release, being capable of destroying anything they come into contact with, whether solid or ninjutsu. The Third also noted that this form of nature transformation had greater dynamic and flexibility to it and is superior to other kekkei genkai or kekkei tōta. Once applying an advanced form of Yin-Yang Release to them, Obito could even halt the Summoning: Impure World Reincarnation's regenerating process.

Eventually, Obito managed to regain control over his mind and subsequently tame the power of the Ten-Tails, undergoing another transformation. In this new form, his appearance becomes very similar to the Sage of the Six Paths. The protrusions on his back now form the collar and coattails of a haori-like coat. Two horns sprout from his forehead; the left smaller than the right. Additionally, he gains six magatama markings across his chest, resembling the Sage's necklace. He also now produced ten chakra orbs, eight of which floated behind him in a halo-like formation, while two floated over the backs of his palms. However, these orbs are incapable of nullifying senjutsu based attacks, and despite his body's durability he can be damaged by them. Even after having the tailed beasts and the Demonic Statue extracted from him, when he came in contact with the new Ten-Tails' jinchūriki, he was able to manifest a black shakujō once again.

After a drawn out battle with Naruto and his allies, Obito demonstrated his own ability to utilise multiple Tailed Beast Ball by first summoning a tree adorned with flowers similar to the one used by the Ten-Tails to focus the chakra of the ball. Later, as both Minato and Naruto continue to press him, Obito decides it is time to move on with the Eye of the Moon Plan, accessing his own version of the Tailed Beast Mode, by assuming the form of the Ten-Tails.

Other Skills
Aside from his proficiency on all major ninja sets, Obito is also versed in a few other unorthodox skills. He has displayed high-level surgical skills, able to remove, preserve, and transplant eyes into himself and others. He is also versed in barrier techniques, using the Uchiha Flame Formation to protect the Demonic Statue of the Outer Path, as well as the Six Red Yang Formation to prevent the Allied Shinobi Forces from escaping his Tailed Beast Ball. He also displayed the ability to perform a series of well-coordinated attacks with his former teacher and partner Madara Uchiha. Obito, while he was the Ten-Tails' jinchūriki, can also sense chakra, as he was able to predict how Sasuke was about to attack him with Amaterasu. He is also versed in sealing techniques that can separate a tailed beast from its jinchūriki or seal a tailed beast to create a jinchūriki, even with a beast such as the Ten-Tails. Obito has also displayed the ability to float in mid air after becoming the Ten-Tails' jinchūriki. He could also absorb chakra from Madara, taking fragments of the One-Tail and the Eight-Tails along with a little portion of senjutsu chakra. Obito is also shown to have a great deal of focus and was able to force Black Zetsu to stay attached to him despite being severely weakened from reviving Madara.

Stats
These stats reflect Obito's abilities at the time of his "death":

Kazekage Rescue Arc
After the death of Sasori, Tobi and Zetsu collect Sasori's ring from his body, which Tobi believes will allow him to join the Akatsuki. Finding Deidara after he and Zetsu find the ninja's disembodied ring arm, Tobi's refusal to return the severed limb resulted in him being strangled by Deidara's legs.

Hidan and Kakuzu Arc
Tobi was seen with the other Akatsuki members to seal the Two-Tails from Yugito Nii, previously captured by Hidan and Kakuzu, to the Demonic Statue.

Three-Tails Arc
Soon after being accepted into the Akatsuki as Sasori's replacement, Tobi is made Deidara's new partner while being assigned to capture the Three-Tails. In the anime, they stopped to get a bite to eat at a dango shop during their search. Deidara anxiously waits for Tobi to remove his mask so that he could see what he looked like underneath, but Tobi turned away, hiding his face. When they finish eating they split up. Tobi eventually finds Konoha ninja using the Four-Corner Sealing Barrier and deduces that that the technique was to seal the Three-Tails. He informs Deidara of his discovery and they approach and kill the two ANBU put in charge of the sealing.

When they locate the Three-Tails, Tobi tries to convince Deidara to fight it in his place. While the Three-Tails chases Tobi, Deidara used one of his bombs on it while it was distracted. The rest of the battle goes unseen. After they defeated the Three-Tails, Tobi claims responsibility for the beast's capture, saying his technique was flawless and that it made sense to assign him to the mission. Deidara retorted that Tobi wouldn't have got far without his clay. Tobi fell asleep after making another cheeky comment, much to the anger of Deidara, who "woke him up" by detonating a clay bomb next to him.

When they get the Three-Tails to an Akatsuki base, the Akatsuki members convene and seal it. When they are done they also seal the Two-Tails (the Two-Tails is sealed before the Three-Tails' capture in the anime).

Itachi Pursuit Arc
When the Akatsuki later receives news that Sasuke Uchiha had defeated Orochimaru, Tobi follows a furious Deidara in his intent to kill Sasuke. When they track him down, Tobi greets Sasuke as a distraction while Deidara attacks with his bombs. Sasuke survives the blast and proceeds to run his sword straight through Tobi. After collapsing, Tobi stands up, unfazed yet complimenting Sasuke for the speed of his attack. Tobi provides support to Deidara for the battle's duration, but Sasuke keeps the advantage. Deidara ultimately resorts to using C0 in an effort to kill Sasuke at the loss of his own life. Though Zetsu reported Tobi's demise to the other Akatsuki members, prompting Pain to remark that he was easily replaceable, Tobi survived. Meeting Pain and Konan in Amegakure shortly afterwards, Tobi instructs the former to capture Naruto so they can extract the Nine-Tails from him.

Seeing a use in Sasuke as Itachi would die soon, Tobi uses his childish facade to hinder the Konoha ninja sent to find either brother. When Zetsu then arrived to inform him that Sasuke had killed Itachi, having expected that outcome, Tobi gets to Sasuke before the Konoha ninja, taking him away. Tobi tended to Sasuke's wounds and, when he woke up, offered to tell him about Itachi. Tobi tried to befriend Sasuke by removing his mask and revealing his Sharingan, something that triggered Itachi's Amaterasu in Sasuke's left eye against Tobi. Tobi retreats into the darkness while he puts out the flames, returning with his mask back on to muse about how Itachi never ceased to amaze him. After Sasuke asked what he was talking about, Tobi revealed that Itachi had most likely set it up so that the sight of his Sharingan would trigger the Amaterasu he had sealed within Sasuke. After Sasuke complained that he was making no sense, Tobi revealed that it was to protect him, and, when Sasuke still didn't believe him, Tobi introduced himself as Madara Uchiha. He proceeds to reveal to Sasuke the Uchiha clan's history, Itachi's secret life, and the true reason for the Uchiha Clan Massacre; however, he lied about his involvement with the Nine-Tailed Demon Fox's attack, saying instead that it was a random natural attack. Sasuke, regretting that he had killed Itachi now that he knew the truth, resolved to destroy Konoha for forcing Itachi into the life he had lived.

Tsuchigumo Kinjutsu Arc
After Utakata was captured, Tobi and the other members of Akatsuki extracted the Six-Tails from him.

Invasion of Pain Arc
Tobi convinced Sasuke and the other members of Taka to start working with Akatsuki, the two groups having Konoha's destruction as a mutual goal. Before they could do that, however, he stated that Akatsuki needed the two remaining tailed beasts. Since Pain was still working on capturing Naruto, Tobi sent Taka to capture the Eight-Tails. After Taka left, Tobi spoke with Zetsu, discussing Akatsuki's actions up to that point. He went on to say that, although they had lost five talented ninja in Akatsuki, all of their efforts had brought him closer to "making Sasuke his".

After Taka captured the Eight-Tails' jinchūriki, Killer B, Sasuke gave him to Tobi for Akatsuki to seal. During the extraction process, it was revealed to be a fake: a severed tentacle made to look like Killer B. Tobi remains silent while Kisame - recently made aware of Tobi's identity as the previous Mizukage - commented that Sasuke had been fooled in his attempt to capture the jinchūriki. The tentacle does not go to waste as Tobi seals the tentacle, a fragment of the Eight-Tails' chakra, into the Demonic Statue of the Outer Path.

Five Kage Summit Arc
Irritated upon learning of Nagato's failure to capture Naruto and wasting the Samsara of Heavenly Life Technique on the Konoha villagers he killed, Tobi sent Kisame to capture Killer B while he catches up to Taka while they were half-way to Konoha. Telling them that Konoha is already in ruins, Tobi convinces Sasuke to follow Zetsu to the Kage Summit in the Land of Iron to kill Danzō, the acting Hokage and a conspirator in the Uchiha's assassination. However, intending to have Sasuke take the Kage hostage for him to facilitate his plans, Tobi instructs Zetsu to expose Taka's presence to the Kage.

Finding Naruto also in the Land of Iron, Tobi decides to personally confront the youth to figure out how he caused Nagato to have a change of heart, but was caught by Kakashi Hatake and Yamato. Rather than fight, Tobi told them about the Sage of the Six Paths, the truth of the Uchiha clan, and Sasuke's descent into darkness because of him. They doubt the validity of what he told them, but he persevered while proclaiming that Naruto and Sasuke are destined to fight someday before disappearing.

As Sasuke was about to be killed by the Kage, Tobi rescued him. He sends Sasuke away, sending Karin with him to heal his injuries. Though disappointed that Sasuke was not more of a match for the Kage, Tobi was nevertheless happy by the development of Sasuke's Mangekyō Sharingan in awakening Susanoo. He then explained his Eye of the Moon Plan to the Kage and those in attendance, concluding by asking for their support by giving him Killer B and Naruto. The Kage refused, so he declared war on them all before disappearing.

Tobi intercepted Danzō while he was fleeing the Summit, fighting his bodyguards Fū and Torune. Although forced to remove his arm because of Torune's nano-sized, venomous insects, Tobi was easily able to dispose of the two before teleporting Sasuke and Karin to their location so he can honour his promise to the former. Tobi observed the battle and was glad when Sasuke is finally able to fully develop Susanoo. When Sasuke emerges victorious, Tobi approaches the dying Danzō to take Shisui's eye, which was implanted in Danzō's right eye-socket. Danzō activated the Reverse Four Symbols Sealing Technique in an attempt to take Tobi and Sasuke with him, but they are able to get out of range in time. Tobi collects Danzō's body and suggests that Sasuke take some time to rest.

At his lab, Tobi discovers that Danzō destroyed Shisui's Sharingan before he died. Cursing him, Tobi gets a new arm and makes plans to retrieve Nagato's Rinnegan to prepare for war. Before he can leave, Zetsu informs him of Sasuke's fight with his former team-mates. Arriving after Sasuke clashed with Naruto, Tobi advises that Sasuke come with him to as they can deal with Naruto another time. Once back at the Mountains' Graveyard, at the youth's insistence, Tobi implants Itachi's eyes into Sasuke before leaving him to recuperate.

Confining the Jinchūriki Arc
Tobi is soon afterwards confronted by Kabuto, who arrived after mastering his new powers. Remembering that Kabuto was once an Akatsuki spy, Tobi tries to kill him for betraying the organisation. Kabuto responds by using the Summoning: Impure World Resurrection to revive five deceased members of Akatsuki (Sasori, Deidara, Itachi, Nagato, and Kakuzu), a demonstration of the sort of "pawns" he can offer Tobi in the approaching Fourth Shinobi World War. In exchange, Kabuto wants Sasuke. When Tobi asked what would happen if he refused, Kabuto responds by summoning a sixth coffin containing Madara Uchiha. Horrified that Kabuto knows that Madara is actually dead, Tobi is forced to accept an alliance, but sets the condition that Sasuke will not be turned over until after the war. Kabuto agrees and sends the summons away. Still uneasy about the revived Madara, Tobi escorts Kabuto into his hideout so he can assess his battle strength and reformulate his plans for war.

Tobi later infiltrates Amegakure to acquire Nagato's corpse before he immediately confronted by Konan. Tobi tries to buy back her cooperation by informing her of his involvement in Yahiko's creation of Akatsuki and Nagato's receiving the Rinnegan, but she doesn't believe him. Konan turns into paper and engulfs Tobi, hoping to use the exploding tags mingled with her paper in order to sacrifice herself to kill him. However, realising her intent, Tobi is able to warp the explosion away - saving both of their lives at the cost of his right arm with the upper part of his mask is broken.

After Konan answers his question while she and Nagato placed their faith in Naruto, Tobi finds himself surrounded by six hundred billion paper explosives. Konan than detonates them all over a period of ten minutes, longer than the five-minute period that Tobi can remain intangible for.

However, to escape the death trap Konan laid out for him, Tobi sacrifices his left Sharingan to use Izanagi and survive the attack while losing the upper left side of his mask in the process. Taking advantage of Konan lowering her guard and thinking she succeeded, Tobi uses a pipe to impale her from behind. Konan attempts a final defensive strike, proclaiming that Naruto will lead them to peace, but Tobi grabs her by the neck as he retorts that he will embrace being the "darkness" that crushes Naruto's "light". He places her under a genjutsu to force her to reveal Nagato's location and adds that she will die when the illusion ends. When Tobi finds Nagato's body, interpreting the corpse's smile as his continued betrayal, he closes the eyes before teleporting the body away to the other dimension.

Once back at his hideout, Tobi replaces his blinded Sharingan with one of Nagato's Rinnegan while getting a new arm, a new outfit, and a new mask. Kabuto complimented him on his efforts to gain new eyes, but Tobi rebuffed the statement, claiming that they were his to begin with. When they receive intel from Kisame about the current location of the jinchūriki, Tobi decides to go capture them. Kabuto offers to go instead if he is allowed to see the White Zetsu Army, adding that he can makes the army stronger if he is allowed to study one of the Zetsu clones. Tobi complies. Much to Tobi's displeasure, Kabuto fails in capturing either Naruto or B, but does bring back Yamato. After Kabuto convinces him to use a genjutsu and the proper drug to extract intel from Yamato instead of using the Human Path ability, Tobi allows Kabuto to use their captive to strengthen the White Zetsu army.

Shinobi World War Arc
When preparations are complete the thousands of Zetsu and many of Kabuto's reincarnated ninja mobilise for war. In the confusion, Kabuto also captures Anko Mitarashi. Tobi suspects that Kabuto led her to their hideout and believes Kabuto plans to have Akatsuki and the Allied Shinobi Forces destroy each other. Although confident that this will not happen, Tobi orders Kabuto to kill Anko. Kabuto refuses on the grounds that he can use Anko to make the Summoning: Impure World Resurrection stronger, something that is in Tobi's best interests.

To alleviate his unease, Tobi demands that Kabuto demonstrate the technique and tell him how to defeat it. To that end he brings out Fū and Torune, who have been kept under genjutsu since they were captured. He breaks Torune's neck and tells Kabuto to use Fū as a sacrifice to resurrect him. Kabuto does what is asked of him. When Zetsu later informs Tobi that Naruto and B are headed to the battlefield, Tobi decides to finally join the fray. He goes to the location of the First Division where he summons the Demonic Statue of the Outer Path. While the Statue decimates the Division, Tobi seeks out the Benihisago and the Kohaku no Jōhei, which contain the Gold and Silver Brothers. Darui and Shikamaru conclude he plans to make use of the brothers' Nine-Tails chakra and try to stop him. He compliments them on guessing his intentions and has the Statue attack them while he escapes with the two items.

As dawn breaks on the following day, Tobi stands behind his own Six Paths of Pain, comprised from the deceased jinchūriki. Tobi leads the Six Paths towards Killer B and Naruto. Naruto headbutts Tobi as soon as they meet, to which Tobi only responds by pointing out that Naruto couldn't even scratch his mask. Naruto notices his new Rinnegan and remarks that it is the same as the "other" Madara's. Realising that Kabuto has revealed his secret, Tobi quietly curses Kabuto before shedding his Madara-identity, embracing the role of "nobody".

Tobi has his Six Paths engage Naruto and a transformed Killer B. B devastates the area in an attempt to force Tobi away while he seals the six jinchūriki, which Tobi counters by having the jinchūriki enter Version 2-like forms. As the jinchūriki overwhelm Naruto and B, Tobi takes advantage of Naruto's distraction and nearly captures him, only to be parried by Might Guy and Kakashi Hatake. In the confusion of their appearance, the Five-Tails breaks free of Tobi's control but he promptly subdues it. He then forces the Four-Tails and Six-Tails to fully transform in an attempt to take control of the battle. The Four-Tails is able to swallow Naruto, leading Tobi to believe that Naruto is finally out of commission. Instead, the Four-Tails manages to communicate to Naruto how Tobi is controlling it. Naruto escapes from its mouth, locates the chakra receiver embedded in the Four-Tails' flesh, and removes it.

With the Four-Tails free, Tobi quickly summons the Demonic Statue of the Outer Path to reseal the beast. He has the remaining jinchūriki transform into their respective tailed beasts to try and finally bring the situation under his control. Despite the overwhelming power of the five tailed beasts, Naruto, working in full cooperation with the Nine-Tails, is able to neutralise all of them and free them from Tobi's influence. Like the Four-Tails, Tobi seals them back into the Statue. Despite the setbacks, Tobi remains confident that he will emerge victorious.

Sometime later, the revived bodies of the jinchūriki, having been kept restrained by a transformed Killer B, are released from the effects of the Impure World Resurrection, causing them to once again become lifeless corpses. As this could only mean that Kabuto has failed, Tobi realises that time is running out. With no other option he tosses the Benihisago and the Kohaku no Jōhei into the Demonic Statue's mouth which, in addition to the Eight-Tails' tentacle from the fake Killer B, completes the set of the nine tailed beasts, initiating the Ten-Tails' revival.

Ten-Tails Revival Arc
While the Demonic Statue undergoes its regeneration onto the Ten-Tails, Tobi protects it from Naruto, B, Guy, and Kakashi. Despite their combined efforts they are unable to get past Tobi or damage him. Tobi is even able to turn some of their own attacks against them, such as a lightning-infused kunai that Kakashi is forced to send away with Kamui. After this latter exchange, however, Kakashi notices that Tobi's mask takes damage. Unable to attribute the damage to any of their attacks, Kakashi tests a theory: after Tobi erects a barrier around the Statue, Naruto tries to hit him with a Rasengan. When the attack appears to pass through Tobi, Kakashi hits the Rasengan with Kamui, causing damage to Tobi's arm. Kakashi concludes that his Kamui and Tobi's Space–Time Ninjutsu share the same dimension; that attacks sent to the dimension at the same moment that Tobi has transported his body parts there for safety will do damage to Tobi.

Now that they have a strategy to use against Tobi, Naruto, B, Guy, and Kakashi begin to coordinate their efforts. One of Naruto's shadow clones attacks Tobi, but the attack appears to fail and the clone disappears. The real Naruto attacks immediately afterwards with a Tailed Beast Ball, which Tobi avoids by retreating to the other dimension. There he finds Naruto's shadow clone waiting for him, having been sent there by Kakashi's Kamui. Before he has a chance to react he is hit in the face with a Rasengan, shattering his mask.

His face revealed, Kakashi and Guy recognize him as their old comrade, Obito Uchiha. Guy, surprised with Obito's presence, wonders how he is still alive, while Kakashi confirmed it to be his former team-mate upon seeing both his Mangekyō Sharingan and a visibly crushed right face. When asked how he survived, Obito dodged the question and instead reveals his motivation; Kakashi's inability to save Rin, leading Obito to hate the reality they live in. As Kakashi hesitated to continue, Naruto instead rallied ahead to stop Obito, who promptly attacks with a fire technique. Right after Naruto intercepts the technique with Kurama's tails, Madara Uchiha arrives to Obito's side of the battlefield.

Striking up a conversation as they casually ignore their opponents, Obito is scolded for deviating from the original plan as he gives Madara his gunbai so he deflect several of the giant chakra receiver stakes thrown at them. Left to deal with Kakashi and Might Guy as Madara goes after Naruto and Killer B, after remembering the events that changed his outlook, Obito tells Kakashi that he has nothing left to say to him and that only thing they have left is a final battle. At first, Kakashi was more focused on getting answers that gave a vexed Obito an advantage. But once Obito's deathblow was intercepted by Naruto, Kakashi resolved to fight his former friend to protect his student.

As Obito questioned Kakashi's resolve, he also noted that Kakashi had used the Sharingan to perfect his Lightning Cutter and had even awakened the Mangekyō Sharingan, but remarked that they would see whether or not Kakashi could return from the other dimension in his current condition. Creating a wooden branch from his right arm, Obito attempted to incapacitate Naruto while he warped Kakashi away. Naruto, however, headbutts Obito again, sending him reeling. When Kakashi is later thrown by Kurama, Obito takes the opportunity to warp Kakashi away. Unbeknownst to him however, this was all part of Kurama's plan and his opponents' two-fold attack is launched: as Naruto attacked Obito from the real-world, Kakashi, who had been given chakra by Kurama attacked the parts of Obito's body which had been warped to the other dimension. When Kakashi returned from the other dimension, Obito watched on as the Ten-Tails is revived despite Naruto and Killer B's attempt to destroy it and heralds the end of this world.

Joining Madara atop of the Ten-Tails' head, two tendrils attached themselves to the Uchiha to give them control over it. Wanting to cast the Infinite Tsukuyomi immediately, Obito was dismayed when Madara expressed wanting to test out the beast's power first. As the skirmish continued, and Naruto saved Kakashi from a swipe of the beast's tail, Obito began to see a bit of his younger self in Naruto. As Kakashi, Guy, and the Eight-Tails all ran out of chakra, and stamina, Obito told Naruto of the futility of his friends' struggle against the Ten-Tails. As Naruto refused to give up on his dreams, Obito told him that there was no need for that as within the dream-world, he would make Naruto Hokage. He then had the Ten-Tails prepare and fire a Tailed Beast Ball, but momentarily found himself affected by a presence. This was revealed to be Ino Yamanaka's Mind Body Switch Technique which she used long enough to veer the attack off course. Obito and Madara soon found themselves shrouded in mist with all sensory methods jammed. Lamenting the futility of this, they had the Ten-Tails clear the mist with a powerful swing of its tail and the two men found themselves face-to-face with the remainder of the Allied Shinobi Forces army.

Deeming their efforts futile, Obito explained to Naruto that the members of the Allied Shinobi Forces would go their separate ways when the war ended and that someone else would eventually finish what he and Madara began. After having his statement that there was no hope for this world rebuffed, and being told by Naruto that the majority did not share their ideals, Obito told the young man that he and Madara would just simply have to exterminate everyone else. With the Alliance bearing down on them, the two Uchiha are buffeted by a barrage of attacks which blinded them, as well as robbed their sensory skills once again, as they tried to attack the Ten-Tails as well. With their opposition confronting them directly, as they momentarily stopped the beast's movements in super-heated quicklime cement, Obito and Madara lamented their opposition's tedious efforts as they reveal the Ten-Tails was about to reach maturity.

As the Allied Forces attempt to attack the two Uchiha, the beast emerges in its mature form. They both quickly realise controlling the Ten-Tails will be harder now and use Hashirama's cells to control it better and Obito decides it is time to show them true despair. They both use the beast's power to level several villages until the Tailed Beast Ball reaches the Alliances' Headquarters. The two then discuss how to proceed with their plans and the fact that in order to become the beast's jinchūriki, Madara required a living body which could only be given by Obito sacrificing his own, which was the only reason Madara did not have the beast use a Tailed Beast Ball to eradicate the entire Alliance, leaving the legendary Uchiha at Obito's mercy. Noting that Obito had developed quite the attitude, Obito stated that he always had it, since he never considered Madara an ally. With Obito deciding to teach the Allied Shinobi Forces despair much to Madara's liking, Obito uses the beast as a medium to fire off several wooden projectiles, sending the Alliance into a frenzy.

Opting for a pinpoint attack on Naruto, it is instead intercepted by Neji Hyūga, killing him in the process. Capitalising on this, Obito used Naruto's guilt over Neji's death against him while reminding him of the people he already lost and the loneliness he will drown in again once all of his friends eventually die. Though Obito put Naruto in a very perplexed state, even asking him to join their cause, Hinata Hyūga ruined his attempted manipulation as he had the Ten-Tails attack again. With Naruto entering Tailed Beast Mode again, Obito is shocked when the young man started dispensing the beast's chakra to those on the battlefield. Attacking with the beast once again, his attack is deflected and he later found himself being controlled once more. After the Ten-Tails is immobilised as well, Obito decried his opponents' belief that a fallen comrade should live on in their hearts, noting that it would only fester and become a curse.

Unable to move, Madara lends Obito some of his power to manipulate the beast but their attack deflected nonetheless. Upon hearing Hiashi Hyūga declare that Neji's sacrifice would not be in vain, Obito mocks him and his clan for having a system where members were essentially locked in cages awaiting their deaths. He and Madara are later shocked by the Alliance's counter-attack. Obito is then separated from the Ten-Tails as Naruto's Rasenshuriken while phasing through him, cut off his connection to the beast, while Rock Lee, enhanced by Kurama's chakra, severs Madara's connection with a strong kick. With this, the two Uchiha are forced to retreat to the ground.

Forced to battle the enemies directly, Obito and Madara collaborated their attacks, which fail to kill any shinobi in the Allied Forces thanks to the chakra cloak Naruto provided each of them. Obito chastised Naruto again, noting that he was contradicting himself in saying that he felt closer to his friends when they died, yet was overexerting himself to protect them. Naruto quickly rebuffed Obito's logic, telling him that a loner like him would not understand. As Kakashi prepared to attempt to warp away the beast again, Obito intercepted him noting that he was waiting for Kakashi to make another attempt. As they both use Kamui on the other, they were warped away to Kamui's dimension.

Upon entering Kamui's dimension, Kakashi was able to maintain his balance unlike Obito, allowing him to quickly strike with his Lightning Cutter before Obito could react, only to stop at the last second. Surprised at first, Obito realised Kakashi was still hesistant to fight him. He then mockingly asked Kakashi if he was still plagued by guilt about failing to keep his promise, to which Kakashi pleaded with Obito to stop fighting by reminding him of who he was and that he can return to being that man. However, Obito laughed as he clarifies he did not start this war for them. While passing through Kakashi's Lightning Cutter to seemingly impaling himself, he casts a genjutsu to recreate the scene where Rin was impaled by the same technique. Revealing that he knew the truth behind Rin's death, Obito explains that it was the "fake" world they live in and system of the shinobi nations that made him lose hope.

Despite Kakashi's insistence that he still felt the way Naruto does, Obito stepped back and used the illusion of his injury to clarify that the hellish world they lived in was to blame for the hollowed man he has become. From there, Obito tried to sway Kakashi to his views, using illusions of his younger self and Rin to appeal to Kakashi's happier memories. However, destroying the illusions, Kakashi refused Obito's offer of a dream world on the grounds that it would never heal one's pain while their reality is not all cruel as having friends eases that suffering. Obito scoffed at Kakashi's words, saying that attachments like that are the source of suffering, but was taken back by Kakashi who reminds Obito of the lesson he taught him and that he will make him accept his ideals again by force if needed. Their battle then raged on, resulting in Obito and Kakashi stabbing each other with their respective attacks. Calling for an end to the games, both men dispel the genjutsu they were casting and being their real battle.

This battle resulted in with Obito being mortally wounded by Kakashi's Lightning Cutter-enhanced kunai while he had stabbed Kakashi in the side non-fatally, causing Obito who declared that the war was not yet won to retreat to the real world. Fleeing back to the real world fatally wounded, Madara who sensed Obito's presence on the battlefield once again and noted that he had no more use for Obito and solemnly expressed his regret at not being able to fight Hashirama properly before becoming the Ten-Tails' jinchūriki. Madara then proceeded with his plan and caused the embedded chakra receivers in Obito's body to sprout out. As the right half of Obito's body turned black, the young Uchiha is seemingly forced to use the Outer Path: Samsara of Heavenly Life Technique in order to revive Madara. As the technique takes time to activate, Sasuke and Naruto race towards Obito to attempt to stop him from completing the Samsara of Heavenly Life before Obito is cut down by Minato, who realised that he was the masked man who attacked Konoha years prior. However, Obito managed to resist Madara's control and seal the Ten-Tails, foiling Madara's attempt at revival in the process. Now the beast's jinchūriki, Obito was able to destroy both the Sage Art: Gate of the Great God and Four Red Yang Formation with ease. As Hashirama and the other Hokage noted that Obito's power is now superior to that of the God of the Shinobi, the Uchiha used his new-found powers to destroy large portions of Hashirama and Tobirama's bodies.

Obito soon found himself plastered with explosive tags planted by Tobirama who was able to retaliate to his previous attack. As the explosions detonate, he is shocked to find himself restrained by Hashirama's wood clone and confronted by Tobirama once again. As the Second noted that this technique was one created based off the fighting style for the reincarnated, Obito is bombarded by an onslaught of explosive tags. He, however, emerged from the blast unscathed as the Truth-Seeking Balls continued to protect him. Confronted by Hiruzen, Obito continued to use the substance to cut through the attacks and ultimately destroyed the Third's body as well. Moving to attack again, Obito is shocked when his body abnormally expanded, Minato used the opportunity to attack him in his vulnerable state. Obito is, however, able to counter not only Minato's attack but launch an attack on Naruto as well. Though this attack is initially deflected by Sasuke, Obito is able to break through Susanoo's defence and attack the two young shinobi.

Puzzled at what had happened when the two suddenly disappeared, avoiding his attack in the process, Obito freed the rest of his body before undergoing yet another unwanted modification as he struggled to get accustomed to being the Ten-Tails' jinchūriki. Launching an attack during that time, it becomes clear that Obito is fighting for control of his body against the Ten-Tails and lost the aim of this attack resulting in destroying the right side of his body. Meanwhile in his subconscious, Obito fights to regain control of his consciousness, focusing on a single image of his old team. As the image was ripped apart, so was Obito ripped limb from limb until he was finally able to subjugate the Ten-Tails' power. Emerging from this in a new form even more reminiscent of the Sage of the Six Paths, Obito exclaimed that he had finally taken control before attacking his former teacher. Though Minato seemingly escaped, Obito drew his attention to the ball of mysterious substance which he had left attached to Minato, which had begun to glow and expand.

When Tobirama managed to return the ball to him, Obito was caught in the explosion, but immediately resurfaced unharmed, shielded by the mysterious substance. Countering several attacks from both Tobirama and Minato, as well as another Scorch Release: Halo Gale Jet Black Arrow Style Zero and a Starch Syrup Gun from Gamakichi, Obito hovered into the sky, using his supreme command of Yin-Yang Release to nullify their ninjutsu. When his former teacher, Minato, confronted him with his former ideals and his dream to become Hokage, Obito confronted Minato with his failure to stop both his fall and his attack on Konohagakure sixteen years ago, and how it was from him that he learned how pitiful the position of a Kage is. This lead Naruto to angrily tell Obito that he should not look down on a position only because he was unable to obtain it. With the aid of Tobirama's Flying Thunder God technique, he then successfully strikes Obito with a Rasengan, revealing Obito's weakness against senjutsu.

Noting to himself as he emerged from the rubble that the Ten-Tails' jinchūriki had a weakness such as this and his inability to proper utilise his Kamui technique, Obito declared that the world was coming to an end and that it was about time that he continued the Eye of the Moon plan. Creating an enormous tree in the midst of the Alliance, the four flowers on the plant started to charge a Tailed Beast Ball to attack them with. Obito then quickly traps everyone on the battlefield within the barrier noting that he would not allow them to escape so easily. As he wrapped himself in the mysterious, black substance in preparation for the blow, he decried Minato once again noting that it was the anniversary of Minato and Kushina's death as well. His berating of Minato, however, is greeted by Naruto's words that he would not allow the world to end. Watching on from the safety of he mysterious black substance which had encapsulated him at that point, Obito noted as the Alliance once again got enveloped in Version 1 chakra cloaks that something of that low calibre would not stop his attack. As he willed the world to disappear and launched the balls, Obito was shocked in the aftermath to see that there were no casualties within the barrier. As Naruto and Minato then tried to perform a sage-enhanced Tailed Beast Ball, Obito manifested the Ten-Tails to begin his Eye of the Moon Plan. The Ten-Tails changed into its final form of Shinju, the god tree, whose branches sought out the shinobi, absorbing all their chakra, killing them. Obito told the shinobi they should rest, having suffered enough, promising their suffering will stop with the Infinite Tsukuyomi.

Capitalising on the shinobi's despair even more, he informed them all that they would not be killed once they surrendered and that their lives would be spared if they resigned themselves to their fate. Despite the grim situation the Allied Forces faced, Naruto's resolve and memories, transferred to his allies telepathically, restored the great army's will to fight, surprising Obito. Obito then was forced to defend himself against the senjutsu-enhanced Naruto and Sasuke's combined attacks, becoming increasingly infuriated with Naruto's unbreakable will. Continuing his battle with the duo, Obito begins to outmanoeuvre the two as well as bolster his defensive stance. As he once again gains the upper-hand on them, he takes the time to decry Naruto's beliefs noting good will ever come out of them. Sending the two crashing to the ground beneath him, he questioned Naruto about why he refused to stay down; the young man's response only served to incense Obito more.

After Naruto's Tailed Beast Mode is equipped with Sasuke's final Susanoo, Obito counters the armoured Kurama with the Sword of Nunoboko as Naruto and Sasuke enlist the aid of Sai and their fellow Konoha 11 allies except Sakura. During the clash, Obito began to imagine how his life would have ended up had he returned to Konoha after Rin died, reunited with to battle alongside his friends, and ultimately became Hokage. This distraction allows Naruto, Kurama and their comrades to slash through Obito and weaken his hold on the the Ten-Tails. This allows Naruto, Gaara, and Killer B to extract the tailed beasts with the aid of the entire Allied Shinobi Forces begin.

Struggling to keep the tailed beats, Obito again finds himself reflected on what could have been with Naruto seeing his thoughts. Seeing Naruto before him, stating that they are the same in how they lived as children, Obito attempts to deny caring for his childhood dream as the youth tells him that he is living a lie and intends to remove the mask despite his continued denial. Naruto even tells Obito that only subjugate the Ten-Tails because he refused to give up his memories of his genin team. Though he attempts to strangle Naruto before being punched off, Obito begins seeing Naruto as his younger self completely. As Obito continues to tell himself he prefers to be alone, Naruto grabs Obito and forcibly drags him over, telling Obito it is time to rejoin his friends and not underestimate them. Once the Allied Shinobi Forces manage to separate the nine tailed beasts' chakra, Obito reverted to his original form and wondering if Naruto and Kakashi were right about him all along while looking at the hand he remembered Rin regularly grabbing to drag him along.

By that time, as Sasuke was about to kill him, Kakashi returns from the other dimension and pins the defeated Obito, accepting his fate. But Minato intervened, having Kakashi stand down after telling him that Naruto's persistent scolding had reached Obito. Obito then states that Rin was the only light in his life and that losing her left him in darkness. He further explains that he felt the world was hopeless afterwards and that everything he's seen along his path confirmed that belief. Kakashi shocks Obito by admitting that he was never completely sure of Naruto's worldview yet states it has a better success rate than Madara's. Asking Kakashi why he would choose Naruto's way, Obito learns that the youth inspires others to aid him.

As he reflected on the past, Obito decided to use the Samsara of Heavenly Life Technique as penance for his actions noting that there was no other way to atone for them. While in this weakened state, Black Zetsu emerged from underground shocking them. As he fused with Obito's body, he forced the Uchiha to use the technique to revive Madara instead.

Return of Madara Arc
When Minato and Kakashi questioned what just happened, Obito weakly explained that Madara had been revived. Black Zetsu then attempted to take Obito's left eye and return it to Madara but is forced to stay merged to Obito when he is attacked by Minato and Kakashi. Now controlling Obito again, Black Zetsu stated that he would force Obito to fight them until he breathed his final breath. Suddenly, the Demonic Statue is extracted from Obito body having been summoned to Madara's side. Black Zetsu again attempted to take the left Rinnegan. Struggling to maintain control of his body, Obito managed to stop Black Zetsu, telling Kakashi to get ready to destroy the eye. Black Zetsu informed Obito that the right Rinnegan he hid was retrieved by a Zetsu clone and returned to Madara already. Around the time when Naruto, Sakura, Gaara and Madara arrived, Kakashi noted that he could no longer sense Obito's consciousness.

Soon afterwards, Black Zetsu managed to steal the Yin half of Kurama inside Minato during the Hokage's attempt to transfer it into his son. Madara, now the Ten-Tails' jinchūriki, arrived to regain his left eye and unable to wait anymore for Black Zetsu to retrieve it. Apologising for the delay, Black Zetsu informed Madara that he had also managed to retrieve the other half of the Nine-Tails' chakra, pleasing Madara. As Black Zetsu attempted to return to Madara, determined to talk to Madara, Obito overpowered Black Zetsu and kept it merged to his body. Asking Madara what he was to him, Obito decided that the legendary Uchiha's response that Obito was also Madara, was no longer a satisfactory answer for someone who wanted to control the world after hearing Naruto's words about what being Hokage meant. Responding to Madara's call to his side, Obito opts to impale his ancestor in the chest while forming a shakujō in his other hand and declaring that he was Obito Uchiha — the man who once wanted to become Hokage.

As his former team-mate and teacher relished in the return of the Obito they once knew, Madara attempted to take back his left eye from Obito, who uses Kamui to evade his attempt. Madara leapt away, but Obito's hand remained in his chest, trying to steal tailed beasts from Madara in an effort to weaken him. Madara mocked Obito, who was able to rip off a small portion of Shukaku and Gyūki. As Kakashi transported Naruto to the other dimension per Obito's request, Madara stopped Obito from following him. Obito figured that Madara would be able to stop him each time he attempted to transport himself due to his advantage in speed. Kakashi joined him and asked if Naruto could be saved if Obito is transported, he confirmed. Obito then asked Kakashi, who noted that it had been a long time since they had been a team, to back him up, as Kakashi asked Obito not to mess it up.

Reminding Madara that two eyes are stronger when they're together, confusing the elderly Uchiha who assumed Obito was talking about the Rinnegan, Obito corrected Madara and stated that he was referring to his original eyes. By combining the power of their individual Kamui, Obito was able to successfully teleported quickly to the other dimension, alarming Sakura. Skeptical on whether or not she could trust him, Obito assured her he would save Naruto. Obito spoke regretfully about his inability to walk straight, but that his path had led him to this point. He sealed Yin Kurama in Naruto, as well as the portions of Shukaku and Gyūki, knowing that Naruto already had a portion of the other tailed beasts' charka inside him. After Naruto finally regained consciousness, Obito teleported Naruto back to the normal dimension. Obito then asked Sakura for a request as an enemy. As Obito struggled to maintain control of Black Zetsu, he begged Sakura to destroy the left Rinnegan. As Sakura prepared to, Madara, having stolen Kakashi's Sharingan and used its power to teleport, arrived in time to stop Sakura's effort.
