Not enough detail in what you need help with... you would need sprites to fight... What kind of fighting game?!?

An entire game, whether the genre, can be pretty complicated. Especially to explain in a single comment.
It would be best to ask about it part-by-part.
I think one major part of a fight game in scratch would be sprite costumes. If you're gonna make a sprite fight, it's gotta look like it's fighting; and scratch does its looks with costumes.
Sprite sheets like this one here provide a pretty good example of what I mean. If I were to make one, I'd make the sprite change its costumes to make it look like it's moving when doing something like a punch or a kick.
