Diamondhead

Diamondhead is a Petrosapien (Petro is a Greek term referring to rocks, sapien referring to an intelligent being; Petrosapien would mean "intelligent rock") from the planet Petropia (a combination of Petro and topos, forming a word similar to "rock place"). The planet was destroyed by Vilgax with the help of Tetrax, who unknowingly helped him create the weapon that destroyed it. This was originally the case, but in "The Secret of Chromastone", it was revealed that the object used to destroy Petropia was a crystal that must be used by Sugilite (the Crystalsapien whose DNA was used for the sample of Chromastone) to recreate the planet. Petropia was reborn in this episode, and all Petrosapiens now resemble Ben's Diamondhead form.


Diamondhead's body is composed of an extremely durable organic crystal, which resembles Taedenite, making him nearly invulnerable. Like Heatblast, Diamondhead can control his crystal physiology at will, allowing him to create crude crystal weapons from any part of his body on demand or fire crystal shards from his hands. This same ability also allows him to regenerate to an extent, such as re-growing lost limbs. In addition to growing crystal from himself, Diamondhead can grow crystal over the ground, and his crystal body acts as a prism, refracting light beams. The one drawback to Diamondhead's crystal form is the crystal itself, which can shatter if exposed to sufficiently strong sonic vibrations, and while Petrosapiens can regenerate limbs, there is a limit to how much damage they can recover from. Ben first transformed into Diamondhead to destroy Vilgax's giant robot sent to take the Omnitrix in "And Then There Were 10". In the planning stages, Diamondhead was set up to be one of the aliens Ben would have discovered later on, while Cannonbolt would have been one of the original ten.[citation needed]


In Ben 10: Alien Force, Diamondhead was regained after Chromastone was temporarily destroyed by Vilgax. He no longer wears the original costume, he instead has a body composed of material similar to that of Chromastone, and the Omnitrix/Ultimatrix symbol moves to his chest from his left-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 completely black pants. He has a belt similar to Kickin Hawk's, Gravattack's, Eye Guy's, Big Chill's, Shocksquatch's and Four Arms'. He wears the Omnitrix symbol on his belt. Also Diamondhead no longer bears the crystals on his chest. The crystals on his back have grown in length also. His chin is also larger. He also wears black shoes with green on the bottom.He re-appears in It Was Them by 16 year old Ben to fight and defeat Slamworm.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. His chin is also larger too. His eyes are green and the Omnitrix is recolored. He first reappears in "Trouble Helix", used by 11-yrs-old Ben for fight Malware.
