Nine-Tails Chakra Mode

The Nine-Tails Chakra Mode is a heightened transformation  unique to  jinchūriki  of the Nine-Tails.

Appearance
While this mode is active, the user gains a chakra shroud with six magatama markings around their neck, two distinctive horns resembling the Sage of the Six Paths' silhouette, swirl designs similar to the Uzumaki clan's symbol, and various other lines extending along their body. Minato's shroud had six additional magatama markings around the collar of his mantle as well as patterns extending from his sleeves to the palms of his hands, the latter of which can also appear on Naruto's shroud at times.

The user's eyes become orange when in this mode and whereas the demon fox cloak is red and releases chakra as boiling bubbles, this form's shroud is yellow and releases chakra as flickering flames. While in this form, Naruto's chakra signature and smell are different, as noted by Neji Hyūga and Kiba Inuzuka respectively. In the anime, a slight dark aura is seen covering Minato's chakra cloak.

Two years later, with both halves of Kurama now sealed as a whole inside him, Naruto's appearance in this form changed again. His chakra mode's markings now has a more simplistic design with thicker lines, two of which wrap around his collar above the six magatama. His centre also has a single dot with a partial circle around it opening at the top and six lines stretching out from it; two of which spread down his legs where the part and wrap around his feet. The other two lines wrap around his waist that connect behind him next to a circle on the centre of his back.

Years later as the Seventh Hokage, Naruto's Chakra Mode changes again. Similar to his Kurama Mode from during the war, his upper body gains an inverted colour-scheme where his shirt turns dark while the lines turn bright, along with the circle on his abdomen being full. His cape also gains similar circle marking around the shoulder area. He also regains the markings on the back of his hands.

Attributes
The Nine-Tails Chakra Mode grants the user enhanced speed, strength, and durability. Naruto becomes strong enough to neutralise White Zetsu with a single kick, and knock down the Demonic Statue of the Outer Path with an uppercut in conjunction with Killer B. Naruto's speed is enhanced to the point that he could dodge the Fourth Raikage using his Lightning Release: Body Flicker Technique; B compared Naruto's own usage of the Body Flicker Technique to the Yellow Flash. Naruto's durability is also high enough to withstand extreme heat and steam-powered physical attacks with only minor injuries, and to endure the Ten-Tails' Tenpenchii, albeit losing his shroud in the process.

While in this form the user can produce chakra arms to interact with their environment or as a means of increasing their manoeuvreability. Naruto initially used the chakra arms as substitutes for shadow clones when forming the Rasengan and its variants, using a single arm to perform the technique's shape transformation, and two arms to accomplish the shape and nature transformation of the Rasenshuriken, which he is able to throw while in this mode. Naruto could also make use of chakra arms to guide his Rasenshuriken to its target. Unable to perform the Tailed Beast Ball without Kurama's cooperation, Naruto initially attempted to create the Tailed Beast Rasengan as a substitue, but ultimately developed the Super Mini-Tailed Beast Ball instead.

Like his predecessor, Mito Uzumaki, Naruto gains Kurama's ability to sense negative emotions, and can also sense chakra across great distances. He is capable of sensing Kurama's chakra signature even while inside a chakra isolation chamber. Naruto's immense life force while in this form causes Wood Release techniques to quickly mature into full-grown trees through close proximity, and White Zetsu to transform into trees upon contact.

Using Nine-Tails Chakra Mode was initially a risk to Naruto as he had to temporarily "shelve" his own chakra in order to access the chakra he removed from Kurama, during which time the fox could drain Naruto's own chakra, potentially resulting in his death. Shadow clones provided an additional risk, as Kurama could absorb chakra from each clone he made simultaneously. Moreover, Naruto also had to be mindful of how long he spent in this mode as there was a limit to the chakra he managed to pull away from Kurama. Despite these risks, Naruto eventually deployed a large number of shadow clones and still managed to maintain this form for an entire night. Gyūki attributed this to the fact that Kurama had willingly stopped taking Naruto's chakra. When Kurama later accepted Naruto's friendship, the two combined their chakra and these limitations no longer applied.

Kurama Mode
By synchronising his heart with Kurama's, Naruto is able to enter the complete version of Nine-Tails Chakra Mode, referred to as. In this form, Naruto's shroud parts down the middle and opens up into a full-length haori, revealing a black undergarment with three magatama on each side of his high collar. The shroud's numerous swirl patterns become complete, black circles, and the whisker-like markings on his face become thicker. In Kurama Mode, Naruto has access to the most powerful secret abilities of a jinchūriki, including the Tailed Beast Ball and Tailed Beast Transformation.

Naruto's speed and strength are once more increased in this form, to the point where he was able to deflect five Tailed Beast Balls by simply moving past them at high speed. He is also able to perform partial transformations in this form, producing only Kurama's head, arms or tails as needed. Naruto is able to transfer his and Kurama's chakra to others, granting them tailless Version 1-like chakra shrouds that greatly enhance their techniques: Hinata Hyūga, for example, was able to deflect one of the Ten-Tails' tails with a single Eight Trigrams Vacuum Palm. Kakashi Hatake stated that the power and volume of the transferred chakra was even greater than when Kurama had directly handed chakra to him, which had improved his Kamui at least three-fold. Despite Kurama's contribution, C claimed the transferred chakra more closely resembles Naruto's own.

Tailed Beast Mode
Like other jinchūriki, Naruto and Minato are able to manifest their tailed beast's body, but rather than physically becoming the beast as other jinchūriki do, their chakra instead forms a translucent construct of Kurama — Naruto's being the same colour as his shroud and Minato's being a darker shade of yellow — and the markings on their backs trail off into a pattern resembling a skeletal structure. Whereas Naruto originally had to enter Kurama Mode before manifesting Kurama, Minato does so without entering an additional form. Similarly, after both halves of Kurama are sealed inside him, Naruto no longer enters Kurama Mode when manifesting the Nine-Tails. Both jinchūriki's eyes become slitted when entering this form.

Kurama is able to control and speak through the construct without taking over its jinchūriki's body, and the jinchūriki can allow others to enter its body, where they can be healed and reinvigorated by its chakra. They are also able to transform Kurama's tails into chakra arms to interact with other large targets, and retain the ability to perform their regular techniques, such as the Shadow Clone Technique or a larger-scale Rasengan. Naruto initially couldn't maintain Tailed Beast Mode indefinitely because he and Kurama had not yet formed a perfect bond. At first they could only last for five minutes, but they extended the time to eight minutes by the time of the Ten-Tails' revival. Naruto later maintained his Tailed Beast Mode for an unspecified time limit during his subsequent transformations. In his final battle with Toneri Ōtsutsuki, Naruto demonstrated the ability to manifest Kurama outside of his body, allowing the two to fight independently.

Senjutsu Influence
Naruto can combine his Nine-Tails Chakra Mode and its various forms with Sage Mode to further enhance his abilities with the power of senjutsu. In this state, Naruto was able to create a senjutsu-enhanced Tailed Beast Ball, as well as add senjutsu chakra to Minato's Rasengan. The eye markings of Sage Mode also reflect on the manifestation of Kurama formed in Tailed Beast Mode, and as Naruto noted, he is able to absorb natural energy more quickly than usual while in Kurama Mode.

Two years after the Fourth Shinobi World War, Naruto utilised his senjutsu-enhanced form against Toneri Ōtsutsuki and showed numerous improvements. His power had improved to the point that he could easily shatter Toneri's defences and overpower the Golden Wheel Reincarnation Explosion, which was capable of cutting the moon in half. Naruto seemingly demonstrated the ability to achieve flight without relying on the Six Paths Senjutsu, and could partition all of the power of this transformation into a single part of his body for enhanced strength.

Six Paths Sage Mode
With the power given to him by Hagoromo Ōtsutsuki, Naruto is able to enter a form known as Six Paths Sage Mode, in which his chakra cloak undergoes another change. The shroud once again forms into a yellow coat with a black bodysuit underneath, but his skin is no longer covered by the chakra, and unlike his usual Sage Mode, there is no pigmentation around his eyes. The bodysuit covers his torso, reaches down his arms to his knuckles, and down his legs to the point just above his sandals. He gains a pattern of six magatama around his collar and the usual marking of the Six Paths Senjutsu, composed of the Rinnegan above nine magatama, on his back. In this state, Naruto is able to fly and manifest nine Truth-Seeking Balls.

Naruto retains the ability to manifest Kurama's senjutsu-enhanced construct, whose might rivals Sasuke Uchiha's Complete Body — Susanoo, being able to deflect its sword slashes with a single tail and clash with it fist to fist. Through the use of shadow clones, Naruto has shown the ability to combine three Kurama avatars into a single construct with three heads and six arms, which greatly resembles his ancestor Asura Ōtsutsuki's own chakra avatar.

Trivia

 * Upon first observing Naruto's chakra shroud in Kurama Mode from behind, Kakashi momentarily mistook Naruto for Minato.
 * Prior to Naruto entering Kurama Mode for the first time, the markings on Naruto's chakra shroud would extend further along his arms and legs whenever he attempted to form the Tailed Beast Rasengan, causing his cloak to briefly progress toward its complete form.
 * In Kurama Mode, the facial markings on Naruto's cheeks resemble Bagua trigrams, specifically the ☰ trigram.
 * In Power, despite the fact that Naruto had not yet subjugated Kurama's chakra, motivated by the Tonika Village orphans' plea to save Dokku and Shiseru, Naruto temporarily assumed an incomplete version of the Nine-Tails Chakra Mode after breaking free from Kurama's influence. During his brief time in the form, Naruto was able to form an incomplete Tailed Beast Rasengan as well. He was also able to enter an imperfect version of the Tailed Beast Mode, in which his seal spread over his body, forming unique markings. Much like Tailed Beast Mode, Naruto's chakra manifested into a replica of Kurama, although it lacked legs and possessed only six tails. In addition to the shroud's tails, Naruto was capable of forming chakra arms to bind his opponents while in this state.
 * When Minato first entered this mode, the bangs at the sides of his face spiked upward and his chakra cloak gained horns similar to those of his son. However, he reverted to his origial hairstyle after being kicked by Obito in chapter 639 and it remained that way from chapter 640 onward. This change was replicated in the anime, with Minato's hair changing after being kicked in Naruto: Shippūden episode 378.
