Kekkei Genkai

are abilities passed down genetically in specific clans. Kekkei Genkai and their related jutsu can't be taught or copied by others, but it is possible to confer the ability to another person if it's localized in a particular organ like the eyes via organ transplant, like Obito passing his Sharingan eye to Kakashi. Kekkei Genkai abilities that work via the user's eye are called dojutsu. Kekkei Genkai is usually translated into Bloodline limit or Bloodlimit techniques.

Kurama clan's Kekkei Genkai
Every few generations a member of the Kurama clan will be born with an incredible talent for genjutsu. The clan member's talent in that field is such that their genjutsu is completely irresistible, so much so that only knocking a person out cold has any chance of awakening them from it. Furthermore, the genjutsu is so powerful that it causes the brain to make anything that happens to the victim within the genjutsu physically real, allowing the clan member to potentially kill their opponents with genjutsu. Such frightening power is not without its drawbacks, however. The user can rarely control the full extent of their abilities, and as such their subconscious will often regulate that power, leading to the creation of a second personality in control of that power. This personality then overwhelms the original, turning the individual into a monster that's a danger to everyone around them.

Ice Release
Ice Release (氷遁, Hyōton, Viz: Ice Style) is the combined nature transformation kekkei genkai of the Yuki clan made up of techniques that combines wind and water-based chakra to create and manipulate ice, forming it into various structures. When the user releases their chakra, the surrounding vicinity becomes cold enough to cause snow to fall.[7] The ice Haku creates is also extremely resistant to fire-based attacks, only melting slightly when coming into contact with Sasuke's flames.

Phoenix Release
This Release is made by Fusing Fire Chakra with Wind Chakra to make a stronger Fire Release, the fire made by this Release is 20% more powerful then the Fire Release.

Dojutsu
The Sharingan (写輪眼, Literally meaning: Copy Wheel Eye, Meaning (Viz): Mirror Wheel Eye) is the dōjutsu kekkei genkai of the Uchiha clan that appears selectively among its members.[14] It is regarded as one of the Three Great Dōjutsu (三大瞳術, San Daidōjutsu, Literally meaning: Three Great Eye Techniques), the others being the Byakugan and the Rinnegan.

Mangekyo Sharingan
A Mangekyō Sharingan is distinguished from a normal Sharingan by its appearance, which changes the form of the tomoe seal. The exact design differs for each user, though all resemble pinwheels. It is initially awakened by the trauma suffered from witnessing the death of someone close to the user. Uchiha have historically misunderstood this criteria as the user needing to be responsible for the person's death, and for that reason they developed the practice of killing their closest friends in order to gain the Mangekyō Sharingan

Byakugan
The Byakugan (白眼, Literally meaning: White Eye, Meaning (Viz): All Seeing White Eye) is the dōjutsu kekkei genkai of the Hyūga and Ōtsutsuki clans, inherited from Kaguya Ōtsutsuki.[4] It is regarded as one of the Three Great Dōjutsu (三大瞳術, San Daidōjutsu, Literally meaning: Three Great Eye Techniques), the others being the Sharingan and the Rinnegan.

Hanagan
The Hanagan is a dojutsu unique to members of the Hasu Clan. It has four stages, each with their own name.

Uzutsuyogan
A dōjutsu only manifested in those of both Hyūga and Uzumaki blood, this Kekkei Genkai was unheard of until Hyūga Kato unlocked her own Uzutsuyogan.
