Kekkei genkai refers to an ability tied to heredity; the two terms are not identical.","facts":[["Dōjutsu","Eye technique"],["Kekkei genkai","Hereditary ability"]],"lvl":0,"sections":[{"h":"Eye techniques","t":"Dōjutsu means eye technique: abilities that depend on a special eye. In the first part we see the Uchiha's Sharingan and the Hyūga's Byakugan. Many dōjutsu are kekkei genkai, that is, traits inherited through blood, but they are not synonyms: some kekkei genkai have nothing to do with the eyes, like those that combine two chakra natures into a new element. Each eye grants different perceptions and techniques, and none works without its bearer's chakra and skill.","lvl":0,"ch":"naruto-80","pos":80},{"h":"Transplants and blood","t":"An eye can pass from one person to another. Kakashi receives Obito's Sharingan and uses it for years, though since he is not an Uchiha he cannot deactivate it and it costs him chakra constantly. The transplant passes on the eye's ability, but it does not change the recipient's lineage or give them the clan's other traits. The same principle later applies to other transplanted eyes in the story: the recipient gains a tool, not a new family.","lvl":0,"ch":"naruto-244","pos":244},{"h":"The eye of legend","t":"The Rinnegan, the eye of the Sage of Six Paths, is presented as the rarest of all. Nagato uses it to control Pain's Six Paths and for techniques that touch on life and death. The story of how it reached his eyes shows once again that the bearer is not always the one who awakened it: Nagato is not an Uchiha and received those eyes as a child. The Mangekyō, for its part, shows that each stage of a dōjutsu can have personal patterns and techniques, so two bearers of the same kind of eye do not necessarily do the same things.","lvl":1,"ch":"naruto-606","pos":606},{"h":"The Ōtsutsuki","t":"The origin of the great dōjutsu goes back to Kaguya Ōtsutsuki, who had the Byakugan and a third eye, the Rinne Sharingan. Her sons and descendants inherited different parts of that power, which explains the Sharingan and the Rinnegan in Indra's line. That mythical lineage does not mean all eyes are interchangeable or that combining bloodlines adds up powers: each dōjutsu has its own rules, and mixing bloodlines does not automatically produce a better eye.","lvl":1,"ch":"naruto-679","pos":679},{"h":"Eyes from novels and films","t":"Outside the original manga, other eyes appear. The Chinoike clan's Ketsuryūgan comes from the novel Sasuke Shinden, and the anime adapts it in the last episodes of Shippūden: it allows genjutsu and control of iron-rich liquids such as blood. The Tenseigan appears in the film The Last, when Toneri Ōtsutsuki implants Hanabi's eyes in himself. They are dōjutsu with very specific conditions and are best read according to their source, novel, anime adaptation or film, and not as pieces of the manga.","lvl":1,"ep":"shippuden-488","pos":700},{"h":"The Boruto era","t":"Boruto brings new cases. Boruto's right eye, which the anime calls the Jōgan, perceives things others cannot see, and Momoshiki warns him that the eye will make him lose everything. Eida has the Senrigan, an ability to observe that comes not from a clan but from a modification with Shibai Ōtsutsuki's DNA. These cases show that, in the new era, not all ocular powers come from blood: some are manufactured or received.","lvl":2,"ch":"boruto-75","pos":775}],"characters":["obito","sasuke"],"related":["sharingan","rinnegan","chakra","trasplantes","kekkei-genkai"],"reference":"Naruto, chapters 12–16, 244 and 373–374.","sources":[{"title":"Obito: el Equipo Minato y el sueño perdido","url":"https://naruto-official.com/en/news/01_1706"},{"title":"Madara: infancia, Izuna y la fundación de Konoha","url":"https://naruto-official.com/en/news/01_1663"}],"figures":["
