Metal Mimicry: He could transform into metallic form that grants him increased strength and durability, to the point that a knife to the chest didn't kill him until he returned to human form.
Limited Shape Alteration: After being used as a host body by Maxis, Ironclad retained some of the entity's nanotechnology. This allowed him to morph his metallic form such as extending spikes from his body or morphing his hands into mallet or blades.
