Power Progression

Stage / Realm / Level	Chapter	Notes
Single Tomoe Sharingan	1 23 2	The initial awakened form for Uchiha; their eyes begin evolving from one tomoe. Uchiha Jie’s left eye is shown at this stage.
Two Tomoe Sharingan	17 175 181	An intermediate form documented in Uchiha Jie’s confrontation with Kakashi and among the lower-grade eyes Jie can distribute or experiment with.
Three Tomoe Sharingan	1 7 55 128	A fully developed standard Sharingan form. It grants enhanced perception, copying, and genjutsu potential; preserved pairs can remain active in chakra-rich storage.
Mangekyō Sharingan	1 5 96 113 294	An evolution beyond Three Tomoe, visually distinguished by an individual pinwheel or spiral pattern and capable of suppressing ordinary Three Tomoe Sharingan. Its awakening is associated with extreme emotional pain and tragedy.
Rinnegan (theorized outcome)	53 126 383	Said to be attainable through the fusion of Senju and Uchiha power under exceptionally demanding conditions. Advanced characters like Kakashi Itachi and Nagato are recorded wielding Rinnegan properties or eyes 383.

Appearance

When activated, the Sharingan appears as a scarlet eye with rotating black tomoe. Its appearance changes with advancement, culminating in the distinct pinwheel-like pattern of the Mangekyō Sharingan. 1 5 294

• A Single, Two, or Three Tomoe Sharingan is distinguished by the number of black tomoe around the pupil. 1 17
• Uchiha Jie’s eyes are unusually mismatched: his left eye has one tomoe while his right has three. 1
• Transplanted Three Tomoe Sharingan can appear as ordinary black eyes while inactive, turning red only when chakra is directed into them 55 128.
• Mangekyō activation can cause blood tears, intense neurological strain, and visible fluid discharge around the eyes 80 136 113.

Abilities & Skills

Enhanced Perception

The Sharingan provides exceptional visual processing and can perceive details inaccessible to ordinary eyes.

• Its dynamic visual acuity allows users to track opponents through smoke, darkness, and high-speed exchanges 16 67.
• It can observe chakra flow within another person’s body 173.
• Its heightened clarity can reveal minute physical details, such as fine hairs and pores 55 173.
• Mist techniques can significantly limit the Sharingan’s visual advantage 62.

Ninjutsu Copying

The Sharingan can observe and reproduce certain techniques performed by others.

• Uchiha Jie copies Raikiri and later reproduces the Fourth Mizukage’s Water Mirror Jutsu 61.
• Orochimaru uses his transplanted Three Tomoe Sharingan to copy Kisame’s ninjutsu 136.
• Kurenai successfully copies ninjutsu after receiving instruction in the Sharingan’s basic applications 175.
• Copying has limits: Itachi is unable to reproduce the Fourth Mizukage’s Water Mirror Jutsu, which he identifies as beyond the Sharingan’s capacity 61.

Genjutsu Amplification

Sharingan users can cast powerful ocular genjutsu, often through direct eye contact.

• Looking directly into an opponent’s Sharingan can result in immediate entrapment in genjutsu 17 67.
• Uchiha Jie uses a Sharingan illusion to place Kakashi on a bloodied cross beneath a Blood Moon 17.
• The Three Tomoe Sharingan supports Genjutsu: Meditation Basin Technique, allowing Jie and Hinata to observe a reconstructed past event 24.
• Kurenai’s transplanted eyes greatly strengthen her genjutsu, allowing her to cast a previously powerful illusion without hand seals 173.
• Uchiha possess considerable resistance to genjutsu, though this does not make them immune to stronger ocular illusions 96.

Mangekyō Ocular Techniques

Mangekyō Sharingan grant specialized powers that differ between users 54.

• Tsukuyomi — Draws targets into an illusionary world where the user controls perception and time. Itachi subjects Jie to three days of torture within the technique 1.
  • A weakened Tsukuyomi can be resisted or broken by another Mangekyō user with superior genjutsu knowledge 86.
• Amaterasu — Produces inextinguishable black flames. Its use causes blood tears and can be sealed into a scroll 1 83.
• Susanoo — Creates a massive chakra construct; Itachi initially manifests an orange-red skeletal form capable of blocking powerful attacks 81 82 142.
  • Sustaining and enlarging Susanoo consumes substantial chakra and ocular power 86 142.
• Space-time ocular jutsu — A mysterious Mangekyō wielder creates a vortex that distorts space and absorbs the Fourth Mizukage’s Tailed Beast Ball 99 105.

Izanagi

Izanagi is a high-level Sharingan technique associated with survival and escape.

• Uchiha Jie’s clone-derived eyes were prepared with stored chakra for one-time Izanagi activation, effectively giving their bearer two disposable chances at survival 93.
• Obito considers Izanagi necessary to escape Kakashi’s Lightning Style trap 107.
• Itachi utilizes Izanagi to successfully revive and survive encounters against powerful opponents like Nagato 341.

Drawbacks and Requirements

• The Uchiha awaken and evolve their Sharingan through intense emotional stimulation, commonly trauma, grief, helplessness, or betrayal 96 175.
• Mangekyō use steadily damages vision; repeated use can reduce a wielder’s eyesight toward blindness 2 86 142.
• Mangekyō techniques impose severe chakra and ocular-power costs, particularly Tsukuyomi, Amaterasu, and Susanoo 81 86.
• A transplanted Sharingan continuously drains the chakra of a non-Uchiha host unless controlled or suppressed 17 173 174.
• Root’s transplant subjects suffer rejection reactions, reduced lifespans, and possible early death; even the best-adapted do not match Kakashi’s compatibility 156.
• Awakening is not guaranteed even for children of pure Uchiha blood 175.

Transplantation and Artificial Control

• The Sharingan can be surgically transplanted if its optic nerves are intact and connected through medical ninjutsu 55.
• Tsunade receives a pair of Three Tomoe Sharingan and can activate or deactivate them voluntarily 55.
• Even while Tsunade’s eyes are inactive, her chakra continues to flow into them; chakra from the eyes also enters and merges with her own chakra 55.
• Tsunade’s Senju lineage gives her better compatibility than an ordinary recipient, allowing mutual influence between her chakra and the transplanted eyes 92.
• Because Tsunade’s eyes originated from one of Jie’s clones, Jie can exert weak Mangekyō-based control over her body through them 92 93.
• Orochimaru develops a forehead tomoe mark for Kurenai that routes chakra through her forehead before it reaches her eyes, allowing voluntary activation and preventing constant chakra loss 174.
• The mark is derived from the Hyūga Caged Bird Seal and can also restrict the Sharingan itself 179.

Known Wielders and Recipients

• Uchiha Itachi — Mangekyō user of Tsukuyomi, Amaterasu, and Susanoo; suffers worsening vision and instability from repeated use 1 81 86 142.
• Uchiha Jie — An anomalous Uchiha with mismatched tomoe, multiple genuine pairs created through his ocular techniques, and Mangekyō-based genjutsu and control abilities 1 7 93.
• Hatake Kakashi — Uses Uchiha Obito’s Sharingan and bears the heavy chakra burden of wielding an eye without Uchiha blood 16 17.
• Uchiha Obito — Uses the Sharingan and a space-time technique connected to the Kamui dimension; later relies on Izanagi to evade Kakashi 107.
• Tsunade — Receives Jie’s clone-derived Three Tomoe Sharingan, which gradually change under the influence of Jie’s Mangekyō chakra and her Senju bloodline 55 125.
• Orochimaru — Transplants a pair of Three Tomoe Sharingan into himself for copying techniques and countering genjutsu 128 136.
• Yūhi Kurenai — Receives transplanted Sharingan through Orochimaru’s experiment and gains enhanced genjutsu and copying ability after acquiring a control mark 173 175.
• Shimura Danzō and Root — Possess numerous recovered eyes and conduct transplantation research intended to turn other Konoha ninja into Uchiha-like shinobi 156 166.
• Shisui Uchiha — Noted Mangekyō wielder associated with the strongest genjutsu, Kotoamatsukami 186 383.

Story Role / Major Arcs

Uchiha Clan Extermination

The Sharingan becomes a central prize following the Uchiha Clan’s destruction. The corpses within the compound are left with empty eye sockets, showing that their eyes were removed during or after the massacre 3 200.

Itachi’s Mangekyō Sharingan establishes the gap between ordinary Uchiha eyes and evolved ocular power, while his use of Amaterasu and Tsukuyomi demonstrates the cost of that power 1 5.

Surviving Eyes and External Transplants

Uchiha Jie preserves active Three Tomoe Sharingan in chakra-rich solution and reveals that he possesses multiple genuine pairs 7.

A pair from Jie’s clone is later transplanted into Tsunade, beginning an unstable fusion between Uchiha ocular chakra and Senju chakra 55 92.

Orochimaru and Root Research

Orochimaru treats the Sharingan as experimental material, implanting eyes into himself and Kurenai while developing methods to manage the chakra burden placed on non-Uchiha hosts 128 173 174.

Danzō converts recovered Uchiha eyes into Root’s military research, eventually proposing the Uchiha Revival Plan: implanting Uchiha bloodlines into Konoha ninja to create a new generation capable of inheriting the bloodline 156 166.

Notable Quotes

“The powerlessness felt witnessing tragedy awakens the Uchiha bloodline, causing their Sharingan to evolve.” 96

“Outsiders envy the Uchiha for their immense power and powerful Kekkei Genkai, but only the Uchiha know in their hearts that this power is bought with the repeated shattering of their inner selves.” 96
