Guy would win. Look how much trouble armstrong had with sloth. Guy is faster then sloth, not as stupid, also his gates are overkill. Armstrong may have nice h2h fighting and long range alchemy but he can't hit what he can't see. Fma characters don't have much of a chance against naruto characters. :\
Yeah, I figured as much. Armstrong might be stronger than Guy if he isn't using his gates, and he also has some pretty large area affect moves. The banter would be amazing, but Guy's speed does kinda' put a conclusive end to this one.
True but guy would use the gates. Armstrong would be too strong most likely without them. We never saw guy's full force without gates however while armstrong we saw everything. When he notices how strong armstrong is and the array of his alchemy he would activate the gates to help him finish him. How far of the gates he would go no one knows. :s
