Diamondhead

Template:Infobox Alien
**Diamondhead** is the Omnitrix's DNA sample of a Petrosapien Subsapien from the planet Petropia.

## Appearance

Diamondhead is a silicon-based life form. His body is composed of durable pale green crystals. He sports two crystal shards on his back and has a sharp point on his head. He wears a uniform which is black with a yellow "V" stripe on the middle of his torso.

Diamondhead wears the Omnitrix symbol on his chest.

## Powers and Abilities

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 crystals he generates.

He can make monstrous and large clusters of crystals, conjuring walls and forming crystal shields and ramps that he can slide upon. He can also generate crystals from the ground at a distance. He can reshape his projectiles into limited shapes, and can also form gaping hands to capture enemies.

Diamondhead's body resembles a living prism, allowing weapons similar to lasers to be refracted and rendered useless.

Due to the natural density of crystal, Diamondhead is extremely durable to physical impacts.

Because of Diamondhead being made out of organic crystals, Diamondhead is immune to aging, as crystals do not age.

Diamondhead can regenerate, but to a limited extent.

## Weaknesses

Diamondhead can crack and shatter if impacted with enough force or exposed to strong sonic vibrations and might even fall unconscious.

While Diamondhead can regenerate limbs, there is a limit to how much damage he can recover from.

The two shards on his back can also leave him stuck on a wall or on other surfaces that he gets knocked into.

Since his body is made of diamond, he can sink in water.
