off what?, even if he fell off a cliff it would have no efect because he is extremeley armored!
so................ how will that win against somone ARMORED?!!! A-R-M-O-R-
bullfrag has basicly no abilities so just face it there is no way bullfrag could possibly beat water hazard!
finally
what do u mean: accept for aggregor?
to win against water hazard u have to have energy attacks or EXTREME physicall strenght. as bullfrag doesnt have anyof them he will be defeated.
personally i think its a bit too soon to make battles for bullfrag as we have seen only a little of him.
