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 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. He wears the Omnitrix/Ultimatrix symbol on his chest.
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 Ben 10: 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.
Powers and AbilitiesDiamondhead'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, and as revealed in the Cartoon Network online game Ben To The Rescue, 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 make monstrous clusters of crystals, conjuring walls and forming crystal shields and ramps. He can reshape his projectiles into limited shapes, and can also form gaping hands to capture enemies. By Alien Force Diamondhead was skilled enough to levitate crystal prisms, as shown in Vengeance of Vilgax: Part 2. In Trouble Helix, he was capable of encasing enemies in crystals. It has been shown that 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. In Vendetta, he was able to absorb energy blasts and redirect them, rather than just refracting. Diamondhead is also resistant to fire and heat, as displayed in Framed.
Diamondhead has superhuman strength, 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.
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, as seen in Arrested Development.
Diamondhead can regenerate, but to a limited extent.
Diamondhead can shatter if 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.
