Diamondhead

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

Appearance
Diamondhead is a silicon-based life form that is about 7 feet in height. His body is composed of durable green crystals. He sports 4 green crystal points on his back and has a sharp head.

In the original series, Diamondhead wore a uniform which is black on one half and white on the other with a black patch on the left chest were the the Omnitrix symbol is.

In Alien Force and Ultimate Alien, Diamondhead's torso is similar to Chromastone's, consisting of indigo crystal which has black lines and dots over it. There are now six crystal points 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 diamonds, thinner arms, a more rounded body, no spikes and a more square head. She wears a uniform like Ben's Diamondhead in original series, except it is half dark blue, half light blue. She wears the Omnitrix symbol on her left chest.l

In Ben 10-Generator Rex: Heroes United, Diamondhead looks more real-world crystal-like due to being drawn in Generator Rex-style. He also has a spike on his elbow, similar to that of XLR8's.

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 completely black pants. He has a belt similar to Gravattack's, Shocksquatch's and Four Arms'. He wears the Omnitrix symbol on his belt. Also Diamondhead no longer bears the crystals on his chest.And uper crystals on his back are now bigger. 11-year old Diamondhead looks almost exactly identical to the original, but the left side of his suit is missing the black patch over the Omnitrix symbol.

Powers and Abilities
Diamondhead has a super dense body which is composed of extremely dense organic green and purple crystals. He is able to manipulate the atomic structure of his crystalline structure and physiology at will, thus allowing him to make crude crystal weapons from any part of his body on demand and fire crystals rapidly from his hands. He can make huge clusters of crystals, creating crystal shields and make ramps. In certain ways, he can even reshape his projectiles into certain shapes and can make giant body parts like hands to capture enemies. He can control the crystals that are not even connected to his body. The same ability also allows him to regenerate to a limited extent, such as re-growing or re-attaching severed or lost limbs. In addition to growing crystals on himself, he can also grow them over other objects. In addition, to his crystallokinesis powers his body itself acts as a living prism, making lasers and weapons similar to useless by refracting the beams. He also has proved strong enough to easily beat Vilgax.

In Alien Force, Diamondhead's powers have grown dramatically, as shown in the episode Vengeance of Vilgax: Part 2. Diamondhead can now levitate crystal pillars. The crystal shards that he fires now explode upon impact.

In Vendetta, he is now shown to have another ability similar to Chromastone's energy absorption and projection abilities, he could absorb and redirect lasers and energy blasts, instead of refracting them in the original series, but most likely still can. Diamondhead is able to survive if shattered, as shown in The Secret of Chromastone.

Diamondhead seems to be able to conjure walls of diamond much faster now, as shown in Couples Retreat.

Weaknesses
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.

Alternate Future
In an alternate timeline's future, Diamondhead has regained predominant clothing. As well as a black-layered shirt, the Omnitrix symbol has moved to the center of his chest. His pants are now white and he has black boots. The diamond shards at his back are now bigger and are only the top ones, instead of the bottom ones. He seems more durable than before, but he still gets shattered by strong sonic vibrations, as shown in Ken 10. Since he is more durable than before, he also became a lot stronger than before. He can properly use his powers now and can create different diamond attacks.
