Sealing techniques and experimental Lightning Release Chakra Mode	88	Learns the Sealing Evil Law Seal and Myriad Phenomena Seal. Uses them to regulate an external Lightning Release source stored in a ring.
Self-generated Lightning Release chakra	120	After more than a year of electrical stimulation, begins refining Lightning Release chakra from his own body. Initial output is weak.
Prototype Sage Arts through a puppet	128	Combines his physical puppet with Little Blue to circulate Sage Chakra without exposing his real body to natural energy. Explicitly an incomplete imitation of Sage Mode.
Lightning Armor	133	His newly awakened Lightning Release makes Chakra Mode more flexible. Dense armor and Body Flicker give him a decisive speed advantage over Pakura.

Fourth Hokage	272	Takes over Konoha and brings Root under his authority alongside Anbu.
Right-eye Rinnegan and Truth-Seeking Balls	318	Installs a Rinnegan, gaining a surge of chakra and access to attraction and repulsion. The eye mediates his combined powers, allowing Truth-Seeking Balls in Sage Mode.
Concentrated Six Paths abilities	328	Uses the Rinnegan’s abilities through his own body rather than distributing them among six puppets; overwhelms Nagato’s Six Paths.
Ten-Tails control and paired Rinnegan	334	Demonstrates the Ten-Tails’ destructive power, then replaces his left Mangekyō with the Rinnegan taken from Nagato. The paired eyes cause another bodily change and an encounter with the Sage of Six Paths.

Background / History

Arrival and life with the Nara family

Toneri comes from another world and possesses knowledge of Naruto and its future events. His understanding is incomplete, particularly regarding later films and Boruto. Early in his journey, he travels toward the Land of Fire with a merchant caravan, intending to reach Konoha 7 25 315.

An encounter with a Cloud Anbu ninja forces him to unleash the Two-Tails’ chakra. He survives through the beast’s healing assistance and is subsequently brought to Konoha. Shikashin Nara houses him in the Nara compound under the stated purpose of providing care, while the arrangement also subjects him to extensive surveillance 14 15 20.

Yoshimi Nara’s welcome gives him a sense of home, but he remains conscious of his political vulnerability as a jinchūriki. He deliberately considers displaying weaknesses to gain Konoha’s trust. Hiruzen later offers Academy enrollment after hearing his modest ambition: opening a cat café and having enough to eat 20 23 27 28.

Training and early missions

Toneri builds his training around survival, defensive protection, and speed. He befriends Minato and Kushina, becomes Orochimaru’s research assistant, and studies medical ninjutsu under Tsunade. His defense of Kushina against Yoshinari’s mockery inadvertently helps Yoshinari awaken the Sharingan 25 28 36 52 53.

After graduation, he joins Tsunade’s team with Yoshinari and Yoshino. Fighting Dikai exposes weaknesses in his weapon control; Orochimaru subsequently supplies a complete short-sword style. Toneri combines this instruction with sealing lessons from Kushina and dangerous experiments intended to imitate Kumogakure’s Lightning Release Chakra Mode 68 69 74 84 88.

The Sunagakure conflict brings both recognition and loss. Toneri kills the already-injured jonin Kisenro, but his effort to change Dan Katō’s fate does not prevent Dan’s death. He helps the survivors escape, treats severe injuries, and gains access to the Scroll of Seals. With Tsunade resting because of hemophobia, he assumes temporary leadership of their team 120 123 125.

Root, Anbu, and the Third Shinobi World War

Danzō pressures Toneri into accepting valuable research material and aligning with Root. Toneri later assassinates the incoming Land of Rice daimyō during a covert operation. The mission places him in unexpected danger when Sakumo, who was supposed to handle its principal threat, fails to appear after an ambush 125 165 166 170.

After returning through the Land of Iron, Toneri discovers that rumors of his death are being used in Konoha’s political struggles. He later becomes known internationally as the Anbu swordsman Blue Cat. Upon leaving Anbu, he teaches Asuma, Guy, and Kurenai while continuing to serve on wartime battlefields 170 173 176 178 208.

Alongside his Konoha duties, Toneri leads the mercenary Kasumi Organization with Kakuzu. He gathers tailed-beast chakra, develops Wood Release, and researches transplanted eyes. His methods become increasingly ruthless: after rescuing Fugaku and Hizashi, he secretly replaces Fugaku’s right Sharingan; he later rescues Rin but alters her memories and keeps her away from Konoha as a future strategic asset 199 223 228 246.

Rise to Fourth Hokage

Repeated clashes with Danzō and Hiruzen erode Toneri’s trust in Konoha’s leadership. A mission to steal Kumogakure’s defense and resource maps exposes further betrayal when the Third Raikage confirms Danzō’s involvement. Back in Konoha, Toneri confronts the leadership, declares his Senju connection, and publicly exposes Root’s experiments on Konoha ninja 253 261 263 266 267.

Toneri secures Root and completes the transition to Fourth Hokage. Hiruzen retires, while Koharu and Homura are released from genjutsu and permitted to retire. Toneri then consolidates departmental authority, prioritizes education and medicine, and negotiates alliances and reparations favorable to Konoha 269 272 273 276 282.

Protecting Konoha and pursuing unification

Minato and Kushina’s marriage intensifies Toneri’s concern about the future attack during childbirth. When Madara attacks, Toneri fights using Wood Release and summons the Three-Tails to buy time. He ultimately subdues the Nine-Tails; Minato, Kushina, and their newborn daughter Naruto survive 287 294 300.

During a later Chunin Exam, Ōtsutsuki Ryojin attacks the Hyuga compound to obtain pure Byakugan. Toneri moves their battle away from Konoha, installs a Rinnegan, and defeats him. Rather than destroy the evolving Tenseigan, he erases Ryojin’s memories and confines him in Root so the transformation can continue 315 317 318 319 320.

As Akatsuki’s tailed-beast campaign escalates, Toneri warns the other villages and calls for a Five Kage Summit. He eventually abandons reliance on gradual growth alone, challenges the other four Great Hidden Villages, and demonstrates the Ten-Tails’ power as part of his intended unification of the Shinobi World 326 327 328 334.

Appearance

Toneri develops from a youth approximately 1.7 metres tall into a young man approximately 1.8 metres tall 173.

• Half-Tailed Beast form: Light-blue cat ears, a black magatama on his chest, and a chakra cloak concentrated around his arms and legs 40.
• Prototype Sage form: His puppet develops blue-and-white cat ears and eye-shadow-like markings while combined with Little Blue 128.
• Operational mask: Uses a white cat-faced mask on Root missions 249.
• Kasumi attire: Appears in a black cloak with a large crimson scythe on his back 224.
• Eye covering: Uses a white eye patch to conceal transplanted dōjutsu; after installing the right-eye Rinnegan, shifts the covering to that eye 319.

Personality

Toneri is pragmatic, observant, and strongly motivated by survival. His initial training plan favors both protection and escape rather than a single offensive specialty. He also manages how others perceive him, considering deliberate displays of weakness and presenting a reassuring smile even when Konoha begins to feel like a cage 23 25 253.

His humor includes boasting, suggestive teasing, and theatrical jealousy over his friends’ romances. Tsunade recognizes that he tends to conceal his full strength until pushed. His poor sense of direction provides a contrasting weakness: the Anbu following him become so frustrated that they start preparing a map for him 36 74 156 287 317.

Toneri genuinely values his adoptive household, friends, and students, but affection does not prevent manipulation. He protects children from dangerous deployments and honors fallen ninja, while also conducting surgery without consent, altering memories, and controlling political figures. His willingness to let dangerous powers develop has a firm condition: they must remain within his ability to control 199 208 238 246 317 319.

Abilities & Skills

Two-Tails partnership

• Possesses unusually large chakra reserves, strong physical recovery, and access to the Two-Tails’ power in emergencies 25.
• Uses partial transformation, fire-enhanced attacks, and Tailed Beast Balls 14 40 199.
• Can amplify an ally’s Fire Release into pale-blue flames, as demonstrated with Fugaku 197.
• Eventually summons the Two-Tails in its true form to fight independently 316.
• Early use exceeds his body’s tolerance and leaves him unconscious; the beast’s healing helps him survive the aftermath 14 15.

Taijutsu and Lightning Release

• Trains his legs, hand seals, tool throwing, and physical conditioning; later intensifies training with Might Duy 25 156.
• Develops an external-source Lightning Release Chakra Mode through cultivated cells, sealing, and regulated chakra release 88.
• Lightning Armor enhances speed and defense enough to ignore many attacks below sufficient power, including ordinary Chunin-level assaults 133 161.
• Can open the first three Inner Gates; by a later assessment, he still cannot properly open the sixth, and the seventh remains beyond reach 161 203.
• Electrical stimulation initially burns skin and kills cells. Recovery depends heavily on the Two-Tails, and the external chakra supply is finite 88 120.

Swordsmanship

• Uses chakra-conducting short swords with Lightning Release and Water Release; the latter helps keep Pakura’s Scorch Release fireballs away 68 133.
• Receives a complete short-sword technique from Orochimaru and further improves while travelling as a swordsman in the Land of Iron 84 170.
• Combines rapid movement with unpredictable swordwork, earning the Blue Cat identity international recognition 173.
• Cuts puppeteers’ chakra threads to disable their weapons 112.
• Initially struggles with unfamiliar weapons and relies more on ninjutsu than a fully developed sword system 68 213.

Medical ninjutsu and research

• Studies under Tsunade and becomes one of Konoha’s top three medical ninja by the time instructor assignments are discussed 52 178.
• Uses the Mystical Palm Technique to heal Fugaku’s shoulder and treats severe battlefield injuries 123 140.
• Conducts cellular cultivation, eye transplantation, and tailed-beast chakra integration experiments 88 155 193 199.
• Can see and manipulate souls, an ability that interests Orochimaru; its mechanics are not detailed in the supplied passages 173.
• Helps Lingxiang improve her chakra control and medical ninjutsu 205.

Sealing techniques

• Sealing Evil Law Seal: Suppresses powerful chakra, including Sage Chakra; used to contain his cultivated Lightning Release source 88.
• Myriad Phenomena Seal: Stores objects inside a marked ring 88.
• Cuts away and seals portions of Shukaku’s and the Four-Tails’ chakra for his own purposes 199 228.
• Seals the Three-Tails inside the Third Kazekage puppet before later summoning it 294.

Puppetry and summons

• Creates physical puppets using replaceable cellular tissue, metal interiors, Shadow Clones, and Little Blue rather than conventional chakra-thread control alone 132 133 194.
• Channels his own chakra through the Third Kazekage puppet to use Magnet Release and Iron Sand 199.
• His clone-powered method prevents him from controlling large numbers of puppets like Sasori 199.
• Summons Aoda, other snakes, Little Blue, and the Three-Tails; later grants Shisui access to the Ninja Cat clan’s summoning contract 69 120 191 294 322.
• Kakuzu’s modifications greatly improve the Third Kazekage puppet, but its heart must remain intact as its central power source 226.

Sage Mode and Wood Release

• Initially experiments with Sage Chakra through a puppet so that petrification would endanger the substitute rather than his real body 128.
• Uses fusion with Little Blue to amplify Sage Mode and produce a massive Lightning Kirin 191.
• Hashirama-cell integration strengthens his Sage Mode, though chakra preparation and limited duration remain practical weaknesses 203.
• Uses Deep Forest Emergence, Wood Locking Wall, and a Wood Golem 223 224 294.
• Acquires Senju scrolls containing advanced Wood Release and Sage Arts, including True Several Thousand Hands 291.
• Excessive Hashirama cells threaten to consume his body; he instead plans to use them to awaken his own dormant Senju traits 287.

Sharingan and genjutsu

• Uses transplanted Sharingan and later Mangekyō Sharingan rather than relying on a documented natural Uchiha inheritance 199 228 246.
• Initially suppresses the Four-Tails for only about half a minute; illusion proves more practical than full domination 228.
• Modifies Rin’s and Ao’s memories and maintains control over Yagura while preserving the Mizukage’s normal memories and habits 246 319.
• His left eye, later identified as Obito’s Mangekyō, accesses Kamui Space. Ryojin’s repulsion interferes with an attempted spatial capture 317 334.
• Mangekyō Yin Release is necessary to counterbalance his awakened Hashirama cells at one stage; removing it risks rapid transformation into a tree 246.

Spatial techniques

• Learns Flying Thunder God after confirming spatial aptitude through Tobirama’s test 205.
• First-stage use depends on prepared marks and initially supports only short-distance travel to stationary formulas 246 250.
• Uses marked identification cards as part of security arrangements for visiting Kirigakure ninja 310.

Rinnegan and Six Paths power

• Uses Almighty Push and Banshō Ten’in for repulsion and attraction 318 328.
• Almighty Push ordinarily has an approximately five-second cooldown, varying with the technique’s range and power 318.
• The Rinnegan mediates his combined Asura- and Indra-related powers, enabling Truth-Seeking Balls in Sage Mode 318.
• Concentrates Six Paths abilities in himself as the Outer Path rather than dividing them among separate bodies 328.
• Later controls the Ten-Tails and equips both Rinnegan, replacing his left Mangekyō 334.

Other combat and operational techniques

• Spiraling Ring: A Rasengan-derived attack incorporating Two-Tails chakra and natural energy; later strengthened with Sage Chakra against Rōshi 224 228.
• Triple Rashomon: A highly chakra-intensive defense that has blocked Tailed Beast Bombs twice by his own assessment 203.
• Fire Release: Uses Great Fireball and a Fire Dragon technique 69 148.
• Water Release: Uses Great Waterfall and water-natured sword chakra 133.
• Infiltration: Applies Root and Anbu experience alongside Orochimaru’s Vanishing Face Skill 166 230.
• Leadership: Combines medical administration, teaching, battlefield command, diplomacy, and covert coercion 136 178 238 273 282.

• Multiple Faces Svāhā — Mito Uzumaki’s technique selected from the Scroll of Seals; selection alone does not establish mastery 123.

Relationships

• Kushina Uzumaki — close friend and sealing teacher. Toneri defends her from ridicule, negotiates with the Nine-Tails on her behalf, and remains subject to her teasing even as Hokage 52 88 207 273.
• Orochimaru — teacher, research collaborator, and source of swordsmanship and chakra theory. Their cooperation increasingly depends on trust and respected boundaries 52 84 287.
• Tsunade — medical mentor, original team leader, protector, and sister-like figure. Supports his professional recognition and disciplines him for reckless solo action 74 82 136.
• Hiruzen Sarutobi — sponsor and predecessor whose trust is repeatedly complicated by political compromise. Eventually relinquishes the Hokage position and assists the handover 27 253 272 273.

• Karatachi Yagura — Mizukage under Toneri’s genjutsu control, enabling concealed influence over Kirigakure 310 319 328.
• Ōtsutsuki Ryojin — enemy whose evolving Tenseigan attracts Toneri’s scientific interest; defeated, stripped of memories, and confined in Root 317 319 320.
