It's all the upper body weight.
With DOA5 Ultimate coming out, I have a prediction on the weight class for the 5 characters:
Lightweight:
Middleweight:
Heavyweight:
Super Heavyweight:
LMFAO! (hella late though)It's them tig ol bitties.
Setups can differ based on character move properties. One character might have moves that work on Helena and Gen Fu but not Bass, and other characters may not. The point is there is a weight difference.
