A couple of points here. [@Card Captor]

1. I think you could add a bit more detail to his description. I think you would know your character best, so I think you should put a little more depth into his description. Some more wouldn't hurt right? lol I also think his personality could use a bit more detail, but I guess I'll let it slide, though it couldnt hurt to add more there either. 

2. His blood type cant just be O. There isn't such a thing as O blood. It is either O+ or O-, pick one. I missed it, but same thing goes for [@WhiteStar19], AB alone isnt a blood type. Is it AB neg or AB pos? Please choose one and change it in ur character sheet accordingly :)

3. But the biggest thing im concerned about is his power. It seems like Orihime's(from Bleach) ability. Is it like a temporal rewind? Or a biological rewind? 

Point A.) Could you give me an example or two of this?----->(or turning chemical changes and complex objects back into their raw parts. When putting something back together, it does this by having the separated pieces fly together violently)<----And could u explain this for me, cause that sounds more like a temporal rewind. He isn't really healing, and is more so just reversing time around an object to revert it back to its original state. Right? I ask because if the pieces fly together violently, can he reverse time around a ball to make it fly back where it came from, or can he reverse a flower back to when it was a seedling? I need some clarity on how it works, cause a power like this needs a bit more detail and explanation of its logistics. 

Point B.) Also, the Imperfections you have said aren't actually imperfections. An Imperfection is a FLAW in the ability. A hiccup. Being in a bad mood is a circumstance. When and if he gets in a bad mood, his powers go out of wack. That isn't inherent nor is it an imperfection. Its not the power thats flawed, its his mood. And seeing as your character is on super friendly juice, the probability of him being in a bad mood is very fickle. 

Secondly, "him having to touch something before he can use his power on it is a pre-requisite. It doesn't make the power imperfect or flawed. Okay, he touches something and can then use the power perfectly. No. lol A pre-requisite isn't a flaw, its just the formality for activating his ability. That's it. I mean, im not saying you can't keep those for what they are, but they arent imperfections. 

(He can not restore life to a living being, and he can not use his powers on himself)<-------Hmmmm...this could potentially be his flaw, but it also just feels like a limitation. His power still works perfectly, he just cant restore life and self regenerate. But I suppose for a power like this, its hard to find a very logical flaw or imperfection. Might be easier to find once you describe Point A for me.
