Chromastone

Chromastone is the Codon Stream's sample of Sugilite from the planet Mor' Otesi. He resembles Eye Guy in his ability to blast lasers from anywhere on his body.

Ben first transformed into Chromastone in the episode All That Glitters when fighting a horde of zombified schoolgirls.

Appearance
Chromastone is a silicon-based lifeform made of highly durable crystal. His body is overall purple body color with several lines and dots. His hands and face are magenta, also sport six magenta shards on his back, two on his chest, and one on the top of his head, resembling a horn. In height, his species is about 6 to 7 feet. His facial structure consists of one large, green, cyclopian eye at the center and his mouth is only visible when speaking. Chromastone's name actually comes from the words "chroma" which means "color" and "stone" meaning "rock."

Powers and Abilities
Chromastone's species are super dense making them nearly indestructible and have the ability to absorb energy like a conductor and channel it into ultraviolet laser beams or intense natural light. He is also able to allow it to pass through his body via refraction which is blasted back to the foe. He can seemingly produce blasts without having to absorb energy, though it may be due to absorption of radiant energy like sunlight, or streetlamps or just ambient energy. As demonstrated in Vilgax Attacks, he can also create energy shields to defend himself from foes. He possesses some degree of super-strength, as he was able to easily overpower a Techadon-enhanced Cash in The Gauntlet. He is also able to create a beam of light like a flashlight, as shown in Inside Man. He is also able to regenerate.He also is very durable. A headbutt from him could be painful due to the horn on his head.

Equipped with the sacred crystal of the Petrosapiens, his genetic donor Sugilite was able to fly and bring back the destroyed planet Petropia. Ben shows this ability in The Creature From Beyond, looking for Lucubra.

Weaknesses
Chromastone's main weakness is that he is unable to absorb any kind of energy when not expecting it or is too weak to do so. An example is given in the episodes Be-Knighted and Fame.

Ben 10: Alien Force
In the two-part season three premiere Vengeance of Vilgax, Chromastone got shattered into pieces by Vilgax. In order to prevent the wearer's health becoming compromised, the Omnitrix reformed the crystal shards of Chromastone's body into Diamondhead. In The Secret of Chromastone, Tetrax used a seismic weapon to shatter Diamondhead's crystalline structure, exposing Sugilite underneath. Tetrax then gave Sugilite a crystal, which he absorbed and then immediately flew off into space(much to the surprise of Ben). Tetrax reveals that Chromastone is the only one who can use the crystal(which serves as back-up for Petropia and its people) to restore his homeworld and it's people. It is later revealed that the Sugilite released by Tetrax is a genetic back-up of Sugilite, Guardian of Petropia. Sugilite's genetic back-up is destroyed by Vilgax, but gives Ben the back-up crystal to finish reviving Petropia's people. Using Diamondhead, Ben revives Petropia. This also revives the original Sugilite, who reveals to Ben that Chromastone still remains within the Codon Stream and is accessible again in the Omnitrix.thumb|300px|right
