Dead Cruiser, your sheet is almost entirely in order. There are only a few things. First off, I'd like for you to consider the "nigh-instantenous" part about him healing from wounds. Cuts and bruises sure, but things like broken bones and exposed innards shouldn't be instantaneously healed and take several moments. That's the only thing that concerns me, the rest of your powers are good. 

And he needs some kind of explanation for why he ends up in the States and why he would ever possibly join the League of Heroes. Nothing major just a few lines about hunting a rogue Vampire or whatever should suffice. Just take care of those things and it'll be ready to go.
