Gravestone is another first-batch Super Trooper designed to be the ultimate gladiatorial combat warrior. He has highly enhanced strength, thickened skin, and bulked muscle, to enable him to withstand most forms of hand-to-hand combat.

Gravestone can be enhanced further by the injection of external stimuli, such as electricity, which supercharges his system, blowing his strength and shutting down his higher brain functions; when supercharged, he is virtually unstoppable. it is best just to avoid him, which, being that he has enhanced speed and dexterity, is difficult at best, and fatal in most cases, like Dr. Owen Negata.
