Diamondhead is a Petrosapien. The strength of Diamondhead is that he can control his crystal physiology at will. This makes him able to create crude crystal weapons from any part his body on demand or fire crystal shards from his hands. He can grow crystal over other objects, too. This ability also allows him to regenerate to an extent, such as regrowing lost limbs. Lasers and other similar weapons are useless against Diamondhead because his crystal body acts as a prism, refracting the beams. The only drawback to Diamondhead’s crystal form is the crystal itself. It can shatter if exposed to sufficiently strong sonic vibrations.
