Steve Fox is a new character introduced in tekken 4, taking the role of the boxer of the tekken series, therefore 98% of his moves are with his hands rather then his feet and thus his kick buttons are replaced with stances.
Steve is a very fast character and very powerful, capable of dealing massive damage and performing some insane combos , but also has a somewhat dificult movelist to get used to. The strong thing about Steve is that he barely has any weaknesses, probably the only one being that he is somewhat sub-par at low-poking (only his right-handed leg hook move is worth using a lot, and that one is slow and unsafe), but his ability to lock-down his opponent, deal massive damage in any situation and having an unlimited skill-ceiling makes him a very dangerous character.
