Diamondhead (CYOA)

* Present
* Albedo

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

## Appearance

Diamondhead is a bulky being made of shiny blue crystal. He has four spikes on his back, the top two being much larger, as well as crystal spikes coming off of his elbows. He wears a two-tone jumpsuit that is black on the left half and pale red on the right half, with the black coming over to form a patch on his right pectoral. He has a black boot on his right foot and a pale red boot on his left. His eyes are yellow.

Diamondhead wears the Omnitrix on the patch on his right pectoral.
After the timeskip, Diamondhead wears an outfit that consists of a black top, pale red pants, and black boots. The Omnitrix has moved to the center of his chest, and his eyes are blue.

## Powers

* Diamondhead's body is composed of extremely thick organic light blue 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 fire crystal shards sequentially out of his hands, and he can create a powerful attack in which he expels shards in all directions, and as he aged the shards, they began to explode upon impact. He can also explode his body parts into crystalline formations, as well as cause crystal constructs to grow from his body.
* He can make monstrous and large clusters of crystals, conjuring walls and forming crystal shields and ramps. 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 is skilled enough to levitate crystal prisms. He is capable of encasing enemies in crystals. He can create crystals inside of objects and cause them to spike out.
* Diamondhead's body resembles a living prism, allowing weapons similar to lasers to be refracted and rendered useless. Diamondhead is also resistant to fire and heat.
* Diamondhead has inhuman physical abilities.
* Due to the natural density of crystal, Diamondhead is extremely durable to physical impacts.
* Diamondhead can survive in the vacuum of space.
* Because of Diamondhead being made out of organic crystals, Diamondhead is immune to aging and time rays, as crystals do not age. Transporter rays will also reflect off his body.
* Diamondhead can regenerate, but to a limited extent.
* Diamondhead can extend his arms.

## Weaknesses

* Diamondhead can crack and shatter if impacted with enough force or exposed to strong sonic vibrations and might even fall unconscious.
	+ The Shield of Ziegel was able to shatter Diamondhead to the point of the Omnitrix activating its failsafe to keep Clock safe, as seen in *Vengeance of Vilgax*.
* 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.
* Diamondhead's physiology can be manipulated by people that can manipulate crystals.
