Well...I could go with the obvious answer and say "Raziel", but I'd actually rather not be a demonic zombified vampire. If I could be Raziel before his execution, that would be pretty badass. Demon wings and all.

Hmmm...aside from that...I'd say Ness from Earthbound. Cool psychic abilities, a constant cash flow and the respect and admiration of the entire world. Can't beat that.
