I would definitely have to say Bruce Irvin. His techniques and kicks are pretty powerful, and his combos can definitely keep an opponent guessing and on guard.
Feng Wei is pretty nice too. His mixture of speed and power can definitely end a match before your opponent is even aware of how to fight back.
Last but not least is King II - his build-up of speed, strength, power, grappling, and strikes makes him a very hard character to figure out and beat when used by the right person.
Born, raised, lived, and escaped from where the wild things are.
