Alright I encourage you all to make your own but if you have the creativity of a walnut there are options.
Now any Kekkei Genkai goes and you will have to post in the Kekkai Genkai families thread for one that isn't already there. Reasoning for this?
Well if you have the Byakugan your going to want to know who's in your family because the Hyuuga clan is closely knit. And it helps in the case you want to adopt a sister/brother/cousin/uncle/family member to help the plot line along.

Rules are:
1. Unless you are a special case, assume the clan name of the Kekkei Genkai you are using. By special case I mean if you gouged out someone else's eyes. I can't really see how you would be a special case otherwise but if I am wrong don't be afraid to prove it.

2. If you do have the Sharingan. Please remember that overuse results in Blindness and/or severe madness. (That last one isn't in the manga but it definitely makes things much more fun! Doesn't apply if you don't want it to but remember overuse WILL have major side effects! Failure to comply will result in consequences!)
