Ferrigno obviously. Look at the size of his arms
All joking aside, I think prime Ferrigno wins, I imagine prime Tyson challenging a 6'4'' 300+ lbs Ferrigno, Ferrigno starts saying ''Hey idk you, why do you wanna fight me?'' but Ferrigno is already getting angry, Tyson is like ''I'll make you my bitch, come on'', Ferrigno is like ''I don't need this bs'' suddenly Tyson punches Ferrigno in the face but Ferrigno quickly blocks the punch with his huge forearm, Tyson starts throwing a flurry of punches that would probably kill a mere mortal, but apparently this doesn't hurt Ferrigno at all, Ferrigno grabs Tyson with both of his arms and takes him to the ground at will, fast, Tyson hits the back of his head against the concrete floor and it's almost unconscious, Ferrigno starts pounding Tyson's face with his huge fist screaming ''I didn't want to do this but you made me do this!!!!!'', the police arrive because apparently someone called the cops and Mike Tyson is dead, his whole face caved in and blood is gushing out of his face and head
