There's only one thing I have a problem with--his personality entry. Don't just include the way he interacts with enemies and the environment, but also how he would react to other circumstances. Of course, you don't have to explain how he would react to every given situation, but tell enough about his personality so that your opponent will know how his mind works. His likes, dislikes, relationship with family and friends; all that good stuff.
Also, if you don't mind, expand on his childhood. Surely his first experiences with the world came before he was
five-years-old? What kind of child was he? Details, details, details are always important. Call me nitpicky, but... alright, fine, I'm nitpicky.
