Diamond head

Diamond Head is a Petrosapien (”Petro” referring to rocks, “sapien” referring to an intelligent being; Petrosapien would mean “intelligent rock”) from the crystal planet Petropia (a combination of the “Petro-” and “topos”, forming a word similar to “rock place”). The planet was destroyed by Vilgax with assistance from Tetrax, who unknowingly helped him create the weapon that destroyed his home. Ben first transforms into Diamondhead in “And Then There Were 10″ when he needed to destroy Vilgax’s giant robot. In the planning stages, Diamondhead was set up to be one of the aliens Ben would have discovered later on, while Cannonbolt would have been one of the original ten.

Diamondhead’s body is composed of an extremely durable organic crystal, making him nearly invulnerable. Diamondhead can control his crystal physiology at will, allowing him to fashion crude crystal weapons from any part his body on demand or fire crystal shards from his hands. This same ability also allows him to regenerate to an extent, such as regrowing lost limbs. In addition to growing crystal from himself, Diamondhead can grow crystal over other objects. Lasers and other similar weapons are useless against Diamondhead, as his crystal body acts as a prism, refracting the beams. The one drawback to Diamondhead’s crystal form is the crystal itself, which can shatter if exposed to sufficiently strong sonic vibrations. While Petrosapiens can regenerate limbs, there is a limit to how much damage they can recover from
