When Ben first battled a giant alien robot sent by Vilgax to retrieve the Omnitrix he used an alien that was strong enough to destroy it. The alien that he used is named Diamondhead and as it turns out he is one of Ben’s strong forms in the Omnitrix.

Species and Home planet: Diamondhead’s species is a petrosapien from the home world, which is called Petropia. See image of Planet below:


Original Series Description: Diamondhead can be described as a silicon-based life form, whose body is composed of extremely thick green organic crystals. He sports four long and short green crystal shards on his back and has a sharp head. Mental note if he tried to give you a hug you have better be careful of those shards. In the Original Series of Ben 10, Diamondhead wears a uniform that is half black on the right and half white on the left. On the left there is a black patch on his shoulder where the Omnitrix symbol is located. When used by Ben 10,000 from an alternate dimension, the shards on Diamondhead’s back where a lot bigger than usual, the lower ones disappeared, and he wears a black colored sleeveless shirt, with white pants and boots. The Omnitrix symbol is located on his chest. See images below:




Alien Force and Ultimate Alien DescriptionWhen used in Alien Force and Ultimate Alien, Diamondhead’s lower body, torso, and the top of his head consist of indigo crystals, which have black colored lines and dots similar to that of Chromostone’s. His eyes are green instead of yellow and have six diamonds on his back instead of the usual four and sport two more diamonds on the front of his chest. The Omnitrix/Ultimatrix symbol is located on his chest. See image below:



Aldebo as Diamondhead Description: When Albedo used his version of Diamondhead, his did look the same as Ben’s except the eyes and the Ultimatrix symbol are red instead of green. See image below:

Ben 10 and Generator Rex Hero’s United DescriptionWhen Diamondhead was used in Ben 10 Generator Rex Hero’s United; the appearance of him consisted of real-world crystals (which is due to the Generator Rex drawing style) and has long sharp crystal blades sticking up from his elbows. See image below:



Omniverse Description: In Ben 10 Omniverse, when used by 11-year-old Ben, Diamondhead’s clothing almost looks the same in the original series except that the left side of his clothing (where the Omnitrix symbol would be) is missing which means that his suit is just half black and half white. The crystals on his back are bigger than usual. His eyes are still green. The Omnitrix symbol has also been recolored and is located on his shoulder. When Diamondhead was used by 16-year-old Ben his uniform is all black with a big green strip that goes down to the middle of the uniform. He wears black pants and black shoes with green on the bottom. The two small crystals on his chest are no longer there anymore. The crystals on his back have grown in length and his jaw appears to be larger. The new Omnitrix symbol is located on a green and white striped belt. See images below:




Mad Ben as Diamondhead DescriptionWhen Mad Ben used his version of Diamondhead his was very different. For example, he has an almost completely black Mad Max style outfit with an orange belt, small orange belts cross on his chest, and orange bandages on his lower arms, thighs, and lower legs. Just ike 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’s Diamondhead has, but has a mohawk consisting of three spikes instead. The eyes are orange instead of green. His Omnitrix symbol is located on his chest is an orange color instead of green as well.



Gwen 10 as Diamondhead DescriptionWhen Gwen 10 used her version of Diamondhead, this version 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. When seen in Omniverse, she almost looked 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.




Special Abilities: The thing about Diamondhead is that since his body composed of extremely thick organic green crystals, his first ability shows that he’s able to manipulating the atomic structure of his physiology at will. This allows him to form his limbs into diamond weapons like blades and bludgeons for example. He is capable at controlling all crystals he generates and can firing them sequentially out of his hands, as it was revealed in the Cartoon Network online game “Ben To The Rescue“. Diamondhead’s second ability is creating powerful attacks with his shards. For example, he can expel his diamond shards in all directions. He can even shoot shards when training or going against enemies. He can age the shards so that they explode upon impact as shown when Ben used him to battle Vilgax. Diamondhead can even explode his body parts into crystalline formations, as shown in the episode, And Then There Were 10. He can even cause crystal constructs to grow from his body, the latter of which he protected Gwen from an energy blast with his body which caused large crystalline spikes to appear on his back and then disappear. His third special ability is that he can make monstrous clusters of crystals, conjuring walls and forming crystal shields and ramps as a way of defending himself and traveling at high speeds. He is shown to reshape his projectiles into limited shapes and can even form gaping crystal-like hands, which can be useful when trying to capture enemies. He can even use his crystals to freeze enemies in place by either touching them or growing them when punching his fist in the ground. Diamondhead’s fourth ability is energy absorption because his body resembles a living prism, allowing weapons similar to lasers to be refracted and rendered useless against him. He’s even immune to fire attacks as well as see in the episode Framed. His fifth ability is crystalkinesis. Crystalkinesis means that he can make diamonds come out of the ground to protect himself, use them as an elevator to go up, and he using them trap his enemies if they try to escape. Also every time he moves he makes a crystal metallic sound. Diamondhead’s sixth ability shows that he has superhuman strength, which he easily used to overpower Vilgax (Ben’s biggest enemy) in a one-on-one brawl. Diamondhead’s seventh ability is age immunity because since he’s made out of organic crystals, he’s immune to aging and time rays because as we all know crystals and diamonds don’t particularly age. His eighth ability is durability because Diamondhead showed that he’s extremely durable to physical impacts as for example when withstanding a punch from Vilgax (wearing a Malware mechamorph armor suit). Diamondhead’s eighth ability shows that he can survive in a vacuum of space. His ninth ability shows that he can extend his arms as shown in the episode Blukic and Driba go to Area 51 and the episode, It’s a Mad, Mad, Mad Ben World out there. His tenth ability shows that he was skilled enough to levitate crystal prisms, as shown in the episode Vengeance of Vilgax: Part 2. Diamondhead’s final ability is regeneration because if he gets cracked he can be able to regenerate himself, but there is a limited extent to the regenerating process. See images below:

Weaknesses: Diamondhead does show to have some weaknesses. The first one is that if he’s knocked into a wall or any other type of surface he can get stuck there. His second weakness is that his diamond body can shatter if impacted with a strong force or if his body is exposed to strong sonic vibrations and might even fall unconscious. Diamondhead’s final weakness is his regeneration ability (that I mentioned before) because while he regenerates his limbs, there is a limit to how much damage he’ll recover from. See images below:
