Hmmm.... sorta depends on my mood..... and who you ask.
I guess I'd have to say for the most part though, a cross between Dante from Devil May Cry (a little from 3, but more from 4), and Gene from God Hand.
A comic relief kind of guy who doesn't take anything too seriously and says a lot of lines that make some people laugh and some people cringe. Kind of over the top sometimes, but steps up to the plate if he feels he HAS to, and doesn't really travel in a big crowd. Just really aloof and carefree.
