Implanting samples of gold, iron, lead, tin and mercury with their own responsometers, Magnus watched the metals take on humanoid shape and personalities. Iron quickly emerged as the backbone of the team. In all the challenges the Metal Men take on, Iron's super-strength and ability to withstand tremendous punishment put him on the front line of action.
