Diamondhead

**Diamondhead** is the Omnitrix's DNA sample of a Petrosapien from the planet Petropia.

## Appearance

Being a silicon-based life form, Diamondhead's body is composed entirely of pale green/blue crystals, which are of a very tough and durable diamond-like substance. He sports four crystal shards on his back and has a sharp head.

Diamondhead has yellow eyes, a black jumpsuit with the lower half of the top being white and the top black portion going downwards into a 'V' shape and the Omnitrix symbol being on the middle of his chest

## Powers and Abilities

Diamondhead's body is composed of extremely thick, pale green silicon crystals. He has the ability to manipulate the structure of his physiology at will, allowing him to form his limbs into crystalline weapons such as blades and bludgeons. Moreover, he can control all the crystals he generates, to the point that he can make them explode on contact or levitate them off the ground. He can fire crystal shards sequentially out of the palms of his hands as projectiles, or morph his entire hands into spikes for easier firing. Diamondhead can also make additional crystal constructs grow out from his body and limbs, and then retract; fast enough to break out of the grip of a being multiple times his size, strong enough to dig into the ground, and sharp enough to slice a falling tree cleanly in half. He can also create crystals immune to sound attacks.

Diamondhead can cause crystal formations to grow rapidly from underneath the ground and erupt to the surface, even at a distance. Using either this method, or by firing crystal shards that grow into which, he can conjure monstrous and large clusters of crystals in the form of walls, shields, ramps, or giant gaping hands to capture enemies; all of which are independent from his body. Being that he can grow these with great speed, Diamondhead can stand on his emerging crystals as he creates them to launch himself in the air or ride on like a board.

Diamondhead can also change the shape and size of his arms and hands without forming more crystals on top. He can extend his arms very far, which allows him to create ramps for others or to propel himself upwards by pushing against the ground. He can also easily regenerate broken pieces of his body.

Apart from just forming weapons attached to his body, Diamondhead can also create independent, fully-formed crystal objects, such as an anchor on a chain, a shield, and a sword.

Diamondhead's crystalline body resembles a living prism, allowing him to deflect and absorb most energy beams and render weapons similar to lasers useless by simply refracting. Similarly, rays generated by dimensional transporter devices will reflect off of Diamondhead's body.

Because Diamondhead is a super dense silicon-based alien, he is immune to Xenocite possession.

Diamondhead is resistant to fire and heat, such as that generated by a Pyronite, much like an ordinary diamond.

If under the effects of a cold virus, Diamondhead is able to sneeze out tiny sharp crystals from his mouth. It is unknown if he can do this when he is not sick, however.

## Weaknesses

Diamondhead is especially weak to sonic vibrations, such as from a Loboan's sonic howls, or an Evolved Sonorosian's Sonic Disks, both of which can render him unconscious. Tetrax also used a vibrating device to completely disassemble Diamondhead's body, although this left him conscious.

If Diamondhead's body becomes completely disassembled, he is unable able to regenerate himself.

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

Diamondhead can be affected by the cold virus.

Despite being immune to effects of aging time rays, Diamondhead can still be affected by other types of time rays, transforming him back to Ben and temporarily immobilizing him.

## History

### Previously

* Ben used Diamondhead when fighting alongside his past self against Vilgax, and Dr Animo.
* On Kenny's 10th Birthday, Diamondhead fought Mot Snikrep. Later, Diamondhead was defeated by Kevin 11,000.

## Trivia

* After the destruction of Petropia and prior to the resurrection of the planet and its people in *The Secret of Chromastone*, Diamondhead and Tetrax were the only known Petrosapiens alive.
* Diamondhead is the only alien other than Way Big to defeat Vilgax.
* Diamondhead is one of Ken's favorite aliens.
* Diamondhead is not made of Taydenite and his crystals have no value.
* Diamondhead's ability to levitate crystal prisms, make explosive projectiles, and absorb energy were probably due to some storyboard artist who was not familiar with Diamondhead's powers.
