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


Diamondhead is a silicon-based life form. His body is composed of durable pale green crystals. He sports four crystal shards on his back and has a sharp head.

In the original series, Diamondhead wears a uniform which is black on the right half and white on the left with a black patch on the left shoulder where the Omnitrix symbol is.

In Alien Force and Ultimate Alien, Diamondhead's lower body, torso, and the top of his head are similar to Chromastone's, consisting of indigo crystal which has black lines and dots over it. There are now six crystal shards on his back instead of 4, and he now also sports two more on the front of his chest. His eyes are green, and he wears the Omnitrix/Ultimatrix symbol on his chest.

In Heroes United, Diamondhead's appearance consists of real-world crystal due to being drawn in Generator Rex's art style. He also has blades on his forearms.

In Omniverse, Diamondhead has clothing almost similar to the first series, except that now instead of half black and half white, it is all black with one large green stripe down the middle up to his belt, and wears black pants. He has a green belt with white stripes on which he wears the Omnitrix symbol. Diamondhead no longer bears the crystals on his chest. The crystals on his back have also grown in length. His jaw is also larger. He also wears black shoes with green on the bottom. There are now only two crystal shards on his back.

11-year old Diamondhead looks almost identical to the original, but the left side of his suit is missing the black patch around the Omnitrix symbol and the crystals on his back are bigger. His jaw is also larger too. His eyes are green and the Omnitrix is recolored.

Ben 10,000 as DiamondheadEdit

Diamondhead's diamond shards on his back are bigger, and the lower ones have disappeared. Diamondhead wears a black sleeveless shirt, white pants and black boots.

The Omnitrix symbol has moved to the center of his chest.

Albedo as DiamondheadEdit

Albedo's Diamondhead looks exactly like Diamondhead in Alien Force and Ultimate Alien but he has red eyes and his Ultimatrix symbol is red as well.

Gwen as DiamondheadEdit

Gwen as Diamondhead has darker and shinier crystals, thinner arms, a more rounded body, no shards on her back, and a more square head. She wears a uniform like Ben's Diamondhead in the original series, except it is half dark blue, half light blue. She wears the Omnitrix symbol on the left side of her chest.

In Omniverse, she almost looks the same as the original series, but now she is somewhat slimmer and is more bluish colored. Her eyes and Omnitrix symbol are pink and she has a hairclip just like Gwen. Her outfit on the left side is different, she now has a black patch on her left chest and a blue cat logo around her Omnitrix. Similar to Gwen's pants, hers come halfway up her calf, and she wears black shoes.

Mad Ben as DiamondheadEdit

Mad Ben's Diamondhead has an almost completely black Mad Max style outfit with an orange belt, a small orange cross on his chest, and orange bandages on his lower arms, thighs, and lower legs. Like Mad Ben's Rath, he has silver spike pads with orange spikes on his knee joints, thighs, lower arms, shoulders, and feet. He lacks the rear head spike that Ben Prime's Diamondhead has, but has a mohawk consisting of three spikes instead. His Omnitrix is on his chest and colored orange, like his eyes.

Powers and AbilitiesEdit

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 fire crystal shards sequentially out of his hands. He can also explode his body parts into crystalline formations,[1] as well as cause crystal constructs to grow from his body, the latter of which he protected Gwen from an energy blast with his body and causing large crystalline spikes to appear on his back and then disappear.

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 can levitate crystal prisms.[2] He was capable of encasing enemies in crystals.[3] 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. He is able to absorb energy blasts and redirect them, rather than just refracting.[4] Diamondhead is also resistant to fire and heat.[5]

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, Diamondhead is extremely durable to physical impacts. He has withstood being punched from Galvan Prime to Galvan B by Vilgax. That incident also shows that 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.[6]

Diamondhead can regenerate, but to a limited extent.

Diamondhead can extend his arms.[7][8]


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. Gwen as Diamondhead lacks this weakness.
