[@Bright_Ops] Ok, the character in general is solid. The Kekkei Genkai is interesting that's for sure. My issues at the following: 

-Personality, could you maybe expand on it? How he is in x recurrent situation, what he does confronted to y, that kind of stuff so we can understand a little more what kind of person he is. If you want to add more to history that'd be greatly encouraged too but not compulsory. 

-The poison. The jutsu in general are fine, it's simply the poison. Now anything involving poisons or infection can only go two ways: It's either very interesting with some nifty gimmicks and mediums to apply them. Or it's downright ridiculous, unbalanced and to put it fairly, stupid. There isn't really a middle ground with poison, so I'd like you to detail the precise effects of the poison depending on the moves (if they vary) or general effect. Fair warning: Stuff like Sasori's poison that cause complete paralysis and inevitable death are not only lame but unbalanced. Instant paralyzing poisons and immediate death types will simply be denied. 

So yeah, hit those changes and I'll check up on it when you're done.
