Kekkei Genkais

Byakugan:
I think everyone knows what that is, but just to be sure ... the byakugan is the kekkei genkai of the Hyuuga family. everyone in the family has white eyes and when the ability is activated you can see through anything, even several kilometers long and behind you. the most talented, like neji, can even see the chakra points, while others only see the chakra system.

Hyoton:
that is the ability of haku. he manipulates water and wind in such a way that ice is formed. the special jutsu is: demonic ice mirrors. anyone who has watched the series carefully knows what it means.

Kurama Clan Kekkei Genkai:
in this clan a child is born every year who has an extraordinary talent for gen-jutsu. it can even kill people with it, for example by painting pictures.

Mokuton:
with this kekkei genkai you can control wooden jutsu, like the first hokage and yamato. it is rather not common, so only the two can do it.Ranmaru's Kekkei Genkai:
Ranmaru has special eyes. they light up red and he can see through all sorts of things. he sees, even through fog jutsus, that the byakugan does not manage. he can also recognize whether someone is dead or still just alive, even if his chakra system is broken.

Sharingan:
kekkei genkai of the uchiha clan. I think everyone knows that enough.
Mangekyo Sharingan:
you can put any person into an illusion, as long as he looks in the eyes. in the illusion you simply control everything! most of the time the opponents collapse, but sometimes they die of heart failure or their brains go weak.

Shikotsumyaku:
this ability belongs to kimimaro and the kaguya clan from which he comes. you check all the bones in your body, which are either getting longer, shorter, fatter, etc.

Soma no Ko:
ATTENTION: you need a second one!
With this kekkei genkai, the partner can let themselves grow together with the body of the other.mostly only one head hangs out at the back the partner can then let a hand or a foot appear at one point on the body, depending on their needs.

so this chapter would be finished, if you have any questions just send me a pn or look at wikipedia in english.
