Bad Diamondhead is the Omnitrix's DNA sample of a Petrosapien from the planet Petropia.
Bad Diamondhead wears a black and white suit with a mint green upper chest, black pants with white and mint boots. He wears the Omnitrix symbol on his chest. If he wants, he can increase the size of the crystals on his back.
Powers and Abilities
Bad Diamondhead's body is composed of extremely thick organic green crystals. He has the ability to manipulate the atomic structure of his physiology at will, allowing him to form his limbs into diamond weapons such as blades and bludgeons.
Moreover, he can control all the crystals he generates. He can fire crystal shards sequentially out of his hands, as well as explosive ones, and can explode his body parts into crystalline formations, as well as make crystal constructs grow from his body. Bad Diamondhead's body resembles a living prism, allowing weapons similar to lasers to be refracted and rendered useless. He is able to absorb energy blasts and redirect them, rather than just refracting. Similarly, rays generated by dimensional transporter devices will reflect off of Bad Diamondhead's body.
Bad Diamondhead has inhuman physical abilities, enough to easily able to overpower Vilgax in a one-on-one brawl. Due to the natural density of crystal, Bad Diamondhead is extremely durable to physical impacts.
Bad Diamondhead is resistant to fire and heat, much like an ordinary diamond. Because he is made out of organic crystals, Bad Diamondhead is immune to aging. Therefore, he is impervious to time rays generated by a Chronosapien or another time-related entity such as Eon, as diamonds do not age.
Despite his enhanced durability, Bad Diamondhead's body can crack and shatter if he's impacted with enough force. Bad Diamondhead is especially weak to sonic vibrations, rendering Bad Diamondhead unconscious. The two shards on his back can also leave him stuck on a wall or on other surfaces that he gets knocked into.
