Iori.

Nobody tops Iori for me in terms of sheer coolness and insanity...

Course, I can't use him for beans...but I love just jumping around with him XD.

There was another cool character I liked in one of the more recent KoF's...she was some sort of boxer? Wearing like a formal suit with cut off sleeves and a tie? I can't remember her name but she was really cool.
