List of Kekkei Genkai

This is a list of the known Kekkei Genkai in Naruto.

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.

Soma no Ko
is the unique ability of Sakon and Ukon that allows them to unify some or all of one's body with the other's body. Typically, Ukon is dormant in Sakon's body, with his head protruding from the back of Sakon's neck. When Sakon is in need of assistance, Ukon can bring out some of his body parts to aid Sakon in blocking or attacking. Examples of this are seen in the forms of and, where Ukon's arms and legs emerge from those of Sakon to add force to his physical attacks.

If needed, Ukon can separate from Sakon's body so that the two can attack independently. While this can be an effective way of double teaming an opponent, Ukon is not used to being outside of or leading Sakon's body and is much weaker when he does so. Despite this, the separated brothers are capable of merging with the bodies of others through. Once they have done so, Sakon or Ukon can destroy the host's cells from the inside, slowly killing them. While within another's body, however, they are vulnerable to whatever injuries befall upon the host, in theory allowing the host to commit suicide to kill either of the brothers.
