Suggested by Sonic Luigi is next to take on Ken, but I don’t think he will be able to do much better. Ken is simply in a different league in terms of proper hand to hand knowledge as well as special abilities. His flame blasts are considerably bigger than Luigi’s. Luigi can try to use his jumps to keep a gap between himself and Ken’s attacks but that will only work for so long. Ultimately Ken always gets his man and that won’t change here. Ken Masters wins.
