Diamondhead (10 years old) 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 (15 years old) has Diamondhead's lower body, torso, and the top of his head were similar to Chromastone's, consisting of indigo crystal which has black lines and dots over it. There were six crystal shards on his back instead of four, and he also sported two more on the front of his chest. His eyes were green, and he wore 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.

Diamondhead is able to absorb various forms of energy, such as lasers and lightning.

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.

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