I was playing it at a pizza joint And i got to fight Onslaught "s hand and got my a$$ Handed to me does anyone know how to win
try to get some air combos on his head, everybody pretty much has a LP, LK, MP, MK, HP air combo to build up your super combo meter. He is easier with people who have vertical super moves like War Machine or aerial super moves like Ryu. I usually wait for him to come to me also so unless you see him on screen just block. It is safer to hit his head than his hand, but if you are using someone with straight forward attacks and special attacks try to do them with his hand down.
