Orochimaru

was one of the Konohagakure's three legendary ninja or Sannin, and was known as the "Giant Snake" (due to his affinity to snakes). He was the primary antagonist for most of Part 1. He was the student that everyone believed would become the Fourth Hokage, but his hunger for power led him to commit dark experiments and practice forbidden jutsu (it has also been explained that his descent into darkness may have been caused by the death of his parents). After the Third discovers what has been going on, Orochimaru left Konoha and forms Otogakure in the Land of Rice. Oto is actually a group of numerous hideouts and bases scattered throughout the Land of Rice and other countries. He was responsible for countless immoral experiments and collecting many ninja with unique abilities in his numerous hidden bases. He wished more than anything to find the ultimate body and improve himself to the state of a god. He has attempted to possess Itachi Uchiha, Kimimaro, Sasuke Uchiha and Guren's body, but all of the attempts have failed for various reasons (Kimimaro had an illness that prevented Orochimaru from possessing him, Itachi's powers allowed him to reverse the jutsu and sever Orochimaru's left hand, Guren was too late to make it to his lair so he had to chose a new body to save his life, and Sasuke also managed to reverse the jutsu and possess Orochimaru's soul instead). Note that the events with Guren only occur in the anime.

Orochimaru's name comes from the Japanese folktale, the Tale of the Gallant Jiraiya, which in turn was inspired by the legend of the Yamata no Orochi. Orochi means "Great Snake" and Maru is a common suffix in male names.

Background
Orochimaru was originally a student of the Third Hokage as a part of a three-man team consisting of himself, Jiraiya, and Tsunade. From a young age, Orochimaru's stood out as a prodigy. His talents, Knowledge, and determination was considered by his sensei a sight seen once a generation. Team Hiruzen mirrored Team Kakashi in nearly every way with Orochimaru being the indifferent genius of the group. Orochimaru was kind as a child and for a lot of his adult life, but later grew to become aloof, arrogant, and somewhat sadistic. His sadistic attitude was, presumably due to the death of his parents, which led him to study kinjutsu. Jiraiya theorized that Orochimaru went down this path in an attempt to forget about his painful memories. Sarutobi in particular had very high hopes for Orochimaru, often berating the clumsy Jiraiya and telling him he should be more like his teammate. After becoming the Third Hokage, Sarutobi hoped that one day Orochimaru would succeed him.

While Orochimaru's ambitions did include becoming the Fourth Hokage, his eyes were set upon goals quite alien to the ideals traditionally associated with the title and emphatically embraced by his teacher. Hiruzen knew that "a shinobi's true strength will manifest when protecting something important," and the Hokage's role is to love and protect the people of the village as if they were a family. For Orochimaru, however, Hokage was nothing more than a potential conquest on the way to what truly interested him - power.

Hiruzen had hoped to make his student see the error of his ways, but as more time passed, it became evident that Orochimaru was a lost cause. This culminated in Orochimaru kidnapping his fellow Konoha shinobi as human guinea pigs. He experimented on them to develop techniques that would grant him immortality, as he had already decided that he would settle for no less than to learn all jutsu in the world (a task that would take much more than one human lifetime). When the many disappearances were finally traced back to Orochimaru, Hiruzen knew that it was his duty to kill him. At the time however, Hiruzen was unable to bring himself to kill his prized student for whom he had had such high hopes for. When Hiruzen finally retired years later he chose a student of Jiraiya's, Minato Namikaze, over Orochimaru as his successor, thus making Minato the Fourth Hokage.

Realizing that he had hit a dead end in his quest to become the ultimate being and therefore had nothing to gain from staying in Konoha, Orochimaru defected from the village and joined the elite criminal organization of Akatsuki. His old teammate, Jiraiya, tried to convince him to reconsider, but to no avail - he betrayed the village and the title of the 'Three Legendary Sannin' (although he is still known as one of the Legendary Three). Although the role Orochimaru played in Akatsuki is unclear, it is known that he was partnered with Sasori prior to his defection (the two apparently had great respect for each other when they were partners; Sasori also claimed that Orochimaru and him did a lot when they were partners in the organization). It was around this time that Orochimaru tried to steal Itachi Uchiha's body. Orochimaru was able to use his Living Corpse Reincarnation Technique, but Itachi used his Sharingan to reverse it and damage Orochimaru's body, causing him to leave Akatsuki to acquire a new body. Thus, he set his sights on Sasuke Uchiha. He eventually founded his own village, Otogakure.

Personality
Orochimaru's various human experiments take place so as to serve two purposes, most prominent of which was his desire to learn every jutsu in the Naruto world. Jiraiya speculates that this was due to the fact that his parents died when he was at a very young age, and flashbacks shown during his battle with the Third Hokage speak to this effect. Perhaps because he wanted to see his parents or as a means of avenging their deaths, he experiments on others to see what kind of modifications the human body can endure and to otherwise harness a subject's unique abilities for himself. Once accomplishing this goal, Orochimaru had hoped to be worthy of the title of "ultimate being". Because a human's lifespan does not allow enough time to learn every jutsu, Orochimaru also experimented on others so as to achieve immortality. By living throughout the ages, Orochimaru needed to never worry about death and thus all the knowledge he gained would never be lost.

Above all else, Orochimaru cares only for himself. He grows bored when there is no conflict or violence in the world, and immediately strikes fear into others when they first meet him. Though he has a number of followers who would do anything for him, Orochimaru treats them as mere pawns. He does not hesitate to send them to their deaths for his own personal benefit, and only finds remorse in their loss if they are unable to properly complete a task. To win over these followers to their disposable status, Orochimaru approaches them with promises of making their dreams, such as obtaining power, revenge, or a purpose to their lives, come true. He applies a cursed seal to many of his stronger subordinates in order to corrode their body and mind, making them more susceptible to his influence and control.

Plans for Revenge
For a while, Orochimaru left Konoha alone, plotting to destroy them when he was ready. The opportunity presented itself with the start of the Chunin exams. With this, Orochimaru saw both a chance to destroy his former home and acquire Sasuke Uchiha's body as his own. Having Sasuke's body would give him the Sharingan, which would aid him greatly in his ultimate goal.

Before the exams began, Orochimaru enlisted the help of Sunagakure, since his own village lacked the necessary strength to defeat Konoha. Already being weakened by their own feudal lord, the village gladly accepted. Orochimaru later killed the Fourth Kazekage and assumed his place to get close to the Third Hokage. He also had the Kazekage's bodyguards killed off and had the Sound Four impersonate them.

During the second part of the Chunin exams, he entered the Forest of Death disguised as a Kusagakure ninja named Shiore as well as having two of his men impersonate Shiore's comrades (The original comrades were killed by Orochimaru. The bodies were disposed of outside of Konohagakure and their faces were stolen). During a confrontation with Naruto, Sasuke, and Sakura, he sealed Naruto's demon fox chakra and branded Sasuke with his Cursed Seal of Heaven. Orochimaru was discovered by Anko, but the exams continued due to his threat of retaliation. His Genin team (consisting of Dosu Kinuta, Zaku Abumi, and Kin Tsuchi) was sent to kill Sasuke, but the three were unaware that they were just measuring posts for Sasuke's power. The three of them were fought off by a combined effort from Sakura Haruno, Rock Lee, and Team 10, who happened to discover them while Sakura was holding them at bay. Sasuke's awakening of his Cursed Seal caused them to retreat.

During the preliminary round for the finals of the Chunin Exams, Orochimaru disguised himself as the jonin sensei for Dosu's team. There he watched Sasuke's performance against Yoroi Akado. While initially hoping Sasuke's emotional state would further release the Cursed Seal, he instead watched in shock at Sasuke's will being strong enough to suppress it, ironically making Orochimaru become awe-struck and desire Sasuke even more.

After Kakashi was able to seal way the mark on Sasuke, Orochimaru confronted Kakashi and complimented him on how strong he had already become. He quickly noted being aware of Kakashi's Sharingan, making no attempt to hide his envy of Kakashi. While Kakashi tried to make Orochimaru reveal his plans, Orochimaru merely revealed that the new Hidden Sound Village was his, and that despite Kakashi's best efforts, Sasuke will eventually come to him seeking power.

Endgame and Failure
During the final part of the Chunin exams, Orochimaru started his attack, hoping to unleash giant snakes outside Konoha while Shukaku was released from Gaara within the stadium. Things did not go as planned however because Gaara grew thrilled about killing someone as powerful as Sasuke and tried to transform into Shukaku before the signal was given. During the attack, Orochimaru attempted to assassinate the Third Hokage, Hiruzen Sarutobi. The Sound Four (disguised as the Fourth Kazekage's bodyguards) were thought dead after ANBU Captain cut them in two. They then come out of disguise and made a barrier so that Hiruzen couldn't escape and so ANBU Captain's squad couldn't aide him. Orochimaru even resorted to the Impure World Resurrection, summoning the departed First and Second Hokages to attack Hiruzen, sacrificing the lives of Zaku and Kin in the process. After a long and spectacular battle, the Third attempted to seal Orochimaru's soul with the Dead Demon Consuming Seal in the same manner as the Fourth Hokage had sealed the demon fox. Orochimaru, however, managed to impale his former mentor with his Kusanagi Sword, weakening the Third to the point that he could only seal the soul in Orochimaru's arms. Having lost the ability to perform ninjutsu, and feeling an agonizing pain, Orochimaru called for retreat. Orochimaru's forces were also repelled by the sudden appearance of most of Konoha's most powerful ninja, including another Sannin, Jiraiya, forcing a retreat. Afterwards, Sunagakure broke ties with Orochimaru after discovering that he killed the Fourth Kazekage.

Reunion
Initially, Orochimaru planned to have his condition healed by appealing to his old teammate, Tsunade, who had since become a legendary medical ninja. He offered to revive her brother and lover, both of whom died in battle years before, in hopes that it would persuade her to cooperate. He also wanted to have the annoucement of Tsunades decision go uninterrupted and arranged for Kabuto Yakushi to assassinate Tsunades' assistant Shizune, after he noticed her angered expression during his first meeting with Tsunade. Though it looked as though he had succeeded at first, it turned out that Tsunade had actually intended to kill him rather than heal him. It was Kabuto who interfered before she could do so. Strangely, Orochimaru almost seemed hurt by the betrayal, and remarked that he really would have brought her loved ones back and promised not to interfere with Konohagakure, a rarity considering his usual self-centeredness and also learned from Kabuto that while he failed in his mission he learned that Jiraiya was nearby. During his following match with Jiraiya where the two were handicapped, after seeing Naruto fighting Kabuto, Orochimaru questioned Jiraiya as to why he would train Naruto who hardly had any ninja talent compared to Sasuke, and realizes that it was due to the fact that Naruto reminds Jiraiya of himself when he was a child. When Naruto defeated Kabuto, fearing Naruto's power and not wanting the Akatsuki to get ahold of him Orochimaru attempted to kill Naruto only to be stopped by Tsunade who then acknowledges herself as the Fifth Hokage. After a large scale battle between him, Jiraiya, and Tsunade, in which all three of their largest summons were used, Orochimaru retreated. Since Tsunade wouldn't heal him, his only remaining option was to take a new host.

Sasuke's Defection
Though Orochimaru was correct in his assessment about Sasuke, who eventually sought him out for power, Sasuke did not arrive fast enough to become Orochimaru's new container. With the pain, bleeding, and gradual decay in his arms (reaching the point when soon it wouldn't matter whether Sasuke arrived or not), Kabuto proposed that Orochimaru take a new host. Kabuto then held a tournament of fights to the death between his prisoners and Orochimaru took over the body of the last man standing, Gen'yumaru. This, while getting rid of his condition, drastically delayed his plans for Sasuke (since he could only take over a new body once every three years). When he took him over, he also noted that parts of Gen'yumaru's will and consciousness would remain in the new body's subconscious.

Fuma Clan Affair
It was revealed that some time before his invasion upon Konohagakure, Orochimaru had tricked Arashi Fuma and some of the Fūma clan to serve him by saying that he would restore their clan to their former glory. After Kagero Fuma, Kamikiri Fuma and Jigumo Fuma's failure to kill Naruto, Jiraiya, and Sakura, Orochimaru killed Kamikiri and Jigumo and later absorbed them into Arashi. Kagero was healed and posed as Kabuto in her confrontation with Sakura. Orochimaru then appeared before Team 7 after Kagero's death. However, it turned out that the "Orochimaru" who was observing the events taking place in the palace was actually the now power-crazed Arashi in disguise. After a long battle, Arashi was defeated and they discovered that Orochimaru was no longer there.

Anko's Past
During Orochimaru's past with Anko Mitarashi, he chose her and nine others to bare his then-newly-obtained Cursed Seal Mark to determine who, out of the ten, would be worthy of becoming his apprentice and, eventually, human vessel. Anko, at that time, respected and admired Orochimaru, typically referring to him as "Orochimaru-sama" (Lord Orochimaru in the English dub) and while he might not have cared for her and viewed her as just another vessel for him to take over, he trusted her enough to show her one of his human experiments before he gave her the Cursed Seal. Though, he might've done the same thing and acted the same way with the other nine "candidates" so that he could build their trust and eventually transform it into devotion as with Kimimaro many years later. Soon after he showed her one of his experiments, he tested his Cursed Seal on Anko and the other nine, and gave her the Cursed Seal of Heaven. After he found her as sole survivor, he estimated the 10 % chance of surviving given a cursed seal. Most of Anko's memories of her time with Orochimaru were erased, due to the Cursed Seal, and Anko could only come up with the conclusion that he abandoned her and left her to die afterwards, while in reality, he gave her the option of coming with him, or staying behind. She chose to stay, and not go with Orochimaru.

Forbidden Experiments
At one point, in between his encounter with Anko and his succession from Konoha, Orochimaru became interested in creating an invincible army of mutated underwater ninja to give Konoha shinobi the ability to breathe, fight, and operate underwater. Realizing it would take too much time on his own, Orochimaru contracted with a rogue medical ninja/scientist named Amachi (with similar ambitions), they began terrorizing the people of the Land of Sea and kidnapped several citizens, notably Isaribi, for their experiments. Eventually, after Sasuke joined him, Orochimaru lost interest with the experiments and ordered Amachi to shut down the project during their last encounter with each other. Amachi, however, secretly refused and continued the experiments without Orochimaru's notice. Feeling cheated out of both his money and time, Amachi planned to use the water-shinobi to exact vengeance on Orochimaru and sent Isaribi to spy and attack ships carrying gold, making her believe that through these deeds, Amachi would return her to her normal human form, when in reality, he planned to dissect her once she was no longer of any use. Afterwards, Amachi enlisted the aid of Kabuto's former shinobi partners Yoroi Akado and Misumi Tsurugi who served as bodyguards. Later, during the Sea Country arc, Amachi was defeated by Naruto and subsequently arrested by Anko's team. Misumi was assumingly crushed to death after Ino Yamanaka tied his arms to some poles in an exploding lab, while Yoroi possibly drowned after his oxygen supply was cut off when Shino Aburame poured bugs down his throat. Isaribi was able to make her come to her senses due to Naruto's insistence and returned with Naruto to Konoha after Amachi's defeat hoping that Tsunade could cure her, which she presumably did.

Top 5 Ninja Battles
In the recap episode, Jiraiya, who could be seen from a TV screen, told both Naruto and Sakura that he was at a top-secret villain base. Jiraiya then brought in a surprise guest, Orochimaru, in situ. Orochimaru called Sasuke in, then Sasuke left saying "Are just you gonna sit talk and all day?", Orochimaru leaves saying "You've angered my young protege I shouldn't keep Sasuke waiting in the dojo".

Fight with the Four Tailed Naruto
After Sasuke's defection, Orochimaru spent the next two and half years training Sasuke to be his next body. When Team Yamato attempted to infiltrate his base for Sasuke, he reappeared during a meeting between Yamato (disguised as Sasori) and Kabuto. Orochimaru explained that he had long ago undone Sasori's "Binding Jutsu" on Kabuto, and had intended on assassinating his former Akatsuki Partner but never got around to it. He then implies that he has seen Sasori's true form. He then called out Naruto, Sakura, and Sai to do battle. He explained that Yamato was the only one out of sixty test subjects that survived one of his genetic experiments to duplicate the First Hokage's Mokuton techniques and his previously unknown ability to "control Tailed Beasts", though he himself did not recognize this until Yamato revealed the abilities himself.

After antagonizing Naruto to the point where he transformed into a four-tailed state, Orochimaru demonstrated a number of new abilities. As well as modified forms of snake summonings, he demonstrated the ability to shed his skin like a snake (repair any damage to his body by doing so), extending large amount of snakes out his mouth with Kusanagi in them, and absorb the strength of attacks thrown at him strengthening his body with the Soft Physique Modification Jutsu. He also demonstrated his immense reserves of chakra (due to the fact he had about 3 bodies in the past) when he summons three Rashomon gates to block the Four-Tailed Fox Menacing Ball that the four-tailed Naruto fired at him. Though they failed to block the entirety of the attack, it was still an impressive feat.

The battle with Naruto came to an end after Orochimaru attempted to stab Naruto with his Kusanagi Sword. However, even the sword was unable to pierce the intense chakra shield protecting Naruto. He commented that his body had reached its limit, as his current body was too weak to continue fighting. It was later shown at his lair, however, that the time he must rest for was quite short.

Afterward, back at Orochimaru's lair, it was made apparent that Orochimaru planned to team up with the militaristic Konoha leader Danzo and destroy Konoha as it is today (the wording would seem to indicate a revolution or takeover, rather than outright annihilation). After a training exercise with Sasuke he interrupted Sai and Naruto to question Sai's loyalty. Though it seemed like Orochimaru would resume his heated fight with Naruto at this point, he instead retreated, saying that he'll let Naruto go in the hopes that Naruto and company will take down more Akatsuki members. When Sasuke attempted to kill his former team with a new technique, Orochimaru and Kabuto appeared and convinced him to spare their lives, at least until they kill more members of the Akatsuki. With Sasuke's "approval", they escaped.

Hunt For The Three-Tails Arc
Sensing that the time was close approaching to change vessels, Orochimaru sent Kabuto to go get a woman named Guren (much to Kabuto's disapproval) so she can help him with his experiment for his preparations for after he takes over Sasuke's Body. During which time Orochimaru also was going through experiments on a child named Yukimaru with unusual powers. Orochimaru eventually called Sasuke and stated it was time to test his strength, which Sasuke calmly accepts. Orochimaru then watches in awe as Sasuke effortlessly takes down a huge army of ninja without being touched once. Although, Orochimaru belittles him for not killing a single one. As Sasuke walks off, Orochimaru admitted that while he used to be recognized as a genius, Sasuke's powers far surpasses his own when he was Sasuke's age.

Noticing that Guren was watching, he offered her another chance to prove herself worthy as Orochimaru's next vessel, to which she was delighted. Orochimaru asked Kabuto how was Yukimaru's powers and he replied saying it was fine and then he ordered Kabuto to tell Guren to head out with Yukimaru on an unknown mission, so his preparations for his plans can be achieved. He said Guren was perfect for this plan and that Guren and Yukimaru's power would be as one if it worked out perfectly.

While not actually him, Orochimaru later appears as an illusion to Naruto. He makes Naruto doubt his belief on whether or not thinking about someone can really make them come back, or if it is even the right place to go to.

Later, it is revealed that Orochimaru chose Guren to aid in this mission not simply because of her Crystal Release, but because he knew she would eventually grow attached to Yukimaru, which he appears to have a use for. He also ordered Kabuto to be ready to eliminate her should she betray him.

Defeat
As Orochimaru slowly began to lose his health. Sasuke saw this as an opportunity to leave Orochimaru (as Sasuke believed he has nothing more to learn from him), and attacked him while bedridden. Orochimaru proceeded to reveal his true body: a large white snake made of several smaller snakes. Sasuke responded by activating his Cursed Seal and destroyed the giant snake's body. Orochimaru then initiated his Living Corpse Reincarnation Technique. However, using his Sharingan, Sasuke was able to control the inner dimension of Orochimaru and suppressed him. Sasuke greets a stunned Kabuto and told him that while he didn't kill Orochimaru, he had taken over. Since his defeat, Orochimaru was suppressed by Sasuke's chakra. During Sasuke's fight with Itachi, though, he used up almost all of his chakra, and Orochimaru forced his way out of Sasuke. Upon seeing Orochimaru and growing impatient with his speech of acquiring immortality, Itachi swiftly used the Totsuka Sword of his Susanoo to seal Orochimaru away and permanently defeat him, removing Sasuke's curse seal in the process. When Kabuto met Naruto, Hinata, and Yamato, he told them how he infused himself with Orochimaru's remains, which are now slowly taking over his body, and hopes to take Orochimaru's power and finish his master's goals as a leader and not a follower.I

Abilities
Being one of the Legendary Sannin as well as a former member of Akatsuki, Orochimaru is an extraordinarily powerful ninja. He was originally selected to become the Fourth Hokage, but the Third feared the evil within him, and gave the position to Minato. His power is so great that around the time of of his invasion of Konoha, the Third feared that no one alive in Konoha could defeat or even fight on equal footing with him, even the Third himself. During the fight with his former teammates, he was able to subdue Jiraiya as well as withstand a horrible beating from Tsunade while his body was in an extremely weakened condition (although Jiraiya was weakened by Tsunade's drug at the time). Orochimaru was also able to fight on equal footing with a Four Tailed Naruto Uzumaki in Part II while his body was in a weakened state, and despite the danger Naruto imposed, he found the battle highly entertaining.

Due to him rarely been shown fighting, he has only displayed a limited amount of techniques, although it stands to reason that in his efforts to learn all existing jutsu, his array of abilities has probably become larger than any other single character, even Kakashi Hatake and the Third Hokage, who were both praised for knowing over 1,000 techniques. His knowledge of jutsu ranges in all forms beyond conventional Ninjutsu.

Ninjutsu
One of the few techniques he was seen using is the Earth Clone Technique, which creates a copy of himself out of mud that can attack on his behalf. He was also able to utilize Wind Release: Great Breakthrough, through which he can level a wide area with a powerful gust of wind. In terms of defensive techniques, Orochimaru uses both Summoning: Rashomon and Triple Rashomon, in which he summons a varying number of large demonic gates that are capable of enduring the most intense forms of damage. If need be, he can also place a Five Elements Seal on an opponent, sealing off their access to chakra and thus rendering them useless in battle.

Immortality Jutsu
In his quest to gain immortality, Orochimaru has made a number of modifications to his body, resulting in his natural form taking on the appearance of a giant, white snake composed of many smaller snakes. This form has the advantages of allowing him to stretch any part of his body to great lengths, regenerate any wound inflicted upon him, and otherwise use the snakes that he is composed of for attack. One of his former ninja, Misumi Tsurugi, knows a less sophisticated version of this technique (though unlike Orochimaru his version is limited). The primary use of the form is with his Living Corpse Reincarnation, which allows him to transfer his soul to another's body and extend his life indefinitely. To use this jutsu, Orochimaru leaves his former body, revealing his true form. Once he has done this, he swallows the new body and transports its current inhabitant to a dimension within himself where he absorbs them, thus allowing him to use their body. Orochimaru can only perform this technique once every three years, which is also around the time that his new body begins to reject him and forces him to find a new host. Although he might leave their bodies behind, the souls of those whose bodies he has taken always remain within Orochimaru's subconscious, causing some of their traits to affect the choices he makes, even if only slightly. While within another's body, Orochimaru uses Vanishing Facial Copy Technique to assume his original appearance. This ability also allows him to take the identities of others by forcefully peeling off their face for his own use, killing them in the process, as he did with the Fourth Kazekage and Shiore's team.

Kinjutsu
Orochimaru can use Summoning: Impure World Resurrection, which allowed him to revive the dead. To perform the technique, Orochimaru must sacrifice a living human so that the soul of the deceased person can be tied to the living world. The sacrificed body is then surrounded with dirt and dust that compacts into the shape of the summoned soul's original body. Although the revived retain their original memories and personalities, thus leaving them out of the control of Orochimaru, he can suppress their free wills with his own special seal to force them to do his bidding. The bodies of the resurrected are also able to regenerate any wound, meaning the only way to defeat them is to remove the soul within them.

Snake Techniques
Orochimaru has an apparent affinity with snakes that, in addition to impacting the appearance and composition of his true form, has caused him to learn a number of snake-related abilities. One such ability is being able to summon giant snakes to fight alongside him in battle, made possible by the summoning contract tattooed to his arms. With Hidden Shadow Snake Hands, Orochimaru can call forth snakes from his sleeves and mouth to attack opponents in large numbers with poisonous bites. Another usage of snakes comes in the form of his Kusanagi Sword: Long Sword of the Heavens, the Kusanagi of Japanese legend. The sword, kept within a mouth of a snake within his own throat, is able to extend to great lengths and can be controlled remotely by Orochimaru. Although he was capable of using the sword normally with great proficiency, it was not uncommon for him to wield it without ever removing it from his mouth. In addition, Orochimaru has shown the ability to regurgitate copies of himself from his mouth.

Creation and Conception
As one of the villains in the story, Kishimoto created Orochimaru as an antithesis to the protagonists' values. His snake-like appearance and related features were intended to make it easier for the reader to recognize that he is a villain. In an interview, Kishimoto asserted that making the villains "flamboyant" was one of his "guiding principles", and attributed this to his desire to have the villains have a "powerful aura".

Following this theme of distinguishing villains, Kishimoto attempted to make Orochimaru's face appear "pasty and sickly," which serves to emphasize the "scary looks" that Kishimoto frequently has Orochimaru performing in the manga. As these occurrences are his "trademark," Kishimoto modifies Orochimaru's appearance and the scene to focus on Orochimaru's face; for instance, highlights that are normally added to Orochimaru's hair are removed and the background is blanked out to create a "creepy atmosphere."

Orochimaru's name and snakelike characteristics are derived from the character of the same name in, in which he utilized snake magic. Other aspects of his character, including his Kusanagi sword, are derived from elements of the Orochi of Japanese mythology.

Trivia

 * Orochimaru borrows heavily from Japanese literature — his name (meaning: Eight-forked serpent circle), as well as those of Jiraiya and Tsunade come from the . The Orochimaru in that story was originally a student of Jiraiya's called Yashagorō, until he was corrupted by snake magic and took on the name Orochimaru. In the same way, Orochimaru was once a childhood friend of Jiraiya's before he turned into the wrong path after seeing his parents dead in a shinobi war.
 * Orochimaru also borrows heavily from the Japanese myth of the, a giant eight-tailed, eight-headed snake killed with the Totsuka Sword by the god Susanoo-no-Mikoto, who found the Kusanagi Sword in one of its tails. This mirrors almost exactly how Orochimaru, while in his Yamata form, wielding the Kusanagi Sword kept inside of him, was sealed into the Totsuka Sword by Itachi Uchiha using Susanoo,.
 * Many of the fans thought that Orochimaru is a Jinchūriki of the Eight-Tailed Beast which was supposed to be a giant eight-headed snake because of his name and the name of a mythical giant snake "Yamata no Orochi". But this speculations were proven to be wrong after Kirābī was introduced.
 * For some reason, after the preliminaries conclude, he is never shown again wearing a Sound headband.
 * Orochimaru was the first Akatsuki member to appear in the series, though well after his defection and before the introduction of the group itself.
 * Orochimaru and Madara are extremely powerful ninja who share certain things in common: they both desired to be Hokage but were rejected, tried in failure to destroy Konoha, went on to become a leader of another village and display an interest in Sasuke Uchiha.
 * Sasuke was the only person to ever disrespect Orochimaru while under his subordinate out of any others of Orochimaru's servants in the anime and manga.
