List of Kekkei Genkai

This is a list of the known Kekkei Genkai in Naurto and a short explanation of each.

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.

Ranmaru's kekkei genkai
Ranmaru has a kekkei genkai ability similar to the Byakugan and Zetsu's spying technique. Its powers allow him to see through solid objects, night vision, create illusions with chakra circulatory systems, and partially predict upcoming attacks. It also allows him to interfere with the workings of the Byakugan, and has other vaguely defined powers regarding vision. When activated, Ranmaru's eyes momentarily glow red. Not much else is known about his kekkei genkai.

Shikotsumyaku
Shikotsumyaku (屍骨脈) is the kekkei genkai of the extinct Kaguya clan, which gave them the ability to manipulate their own skeletal structure. They had free control over the cells responsible for bone growth and replacement, allowing them to manipulate their bones at will. They could protrude their bones out through their skin, change their bone density, and could even completely regenerate a lost bone. An example of this is seen with the Finger Bullet Drill (十指穿弾), which fires the user's fingertip bones like bullets. All this makes their bodies virtually indestructible, and any point of contact on the body could become as sharp as a spear tip, giving them a nearly perfect defense. The ability seems to be rare amongst the clan members, as Kimimaro Kaguya was the only one to exhibit it out of his entire clan.

Most of the Shikotsumyaku abilities came in the form of bone-utilizing dances named after flowers. The most basic of these dances is the Dance of the Camellia (椿の舞), which uses the humerus of either arm as a sword. The Dance of the Willow (柳の舞) uses extensions of bone from the body to attack the opponent, coupled with large amounts of acrobatics to increase the attacks' effectiveness. The defensive Dance of the Larch (唐松の舞) uses growths of the user's preexisting skeletal structure to ensnare the opponent and stab them as the bones are growing. The Dance of the Clematis (鉄線花の舞) is an attack with two parts, the first being Vine (蔓) and the second being Flower (花). With Vine, the user rips out their spinal cord and use it to trap the opponent. Once immobile, the user uses Flower to form the body's strongest bones into a giant drill on the user's arm to crush the stationary opponent. The final dance, Dance of the Seedling Fern (早蕨の舞), creates a giant forest of bone spikes that emerge from the ground and impale the opponent.

Soma no Ko
Soma no Ko (双魔の攻) 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 Multiple Connecting Punches (多連拳) and Multiple Connecting Kicks (多連脚), 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 Parasite Demon Demolition Technique (寄生鬼壊の術). 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.
