Chromastone

Chromastone is the Codon Stream's sample of the Crystalsapien species from the planet Mor'Otesi.

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. He has a purple body, and purple legs and arms with several black lines and dots on them. His hands and face are magenta. He also sports magenta shards all over his body: six on his back, two on his chest, and one on top of his small, purple head, resembling a horn. He also has one, large, cyclopian eye. Chromastone's name actually comes from the word "chroma" which means "color".

Powers and Abilities
Chromastone is a super dense silicon life-form able to absorb energy like a conductor and channel it into laser blasts or less-intense natural light. He can also allow it to pass harmlessly through his body via refraction which can also be blasted back at the foe. Chromastone 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. Chromastone also possesses some degree of super-strength, as he was able to easily overpower a Techadon-enhanced Cash in The Gauntlet. Equipped with the sacred crystal of the Petrosapiens, his genetic donor Sugilite was able to fly and bring back the destroyed planet Petropia.

Weaknesses
The weakness of Chromastone is that he is unable to absorb energy when he is not expecting it or is too weak to do so. He can also get electrocuted when wet.

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 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 the Petrosapien. 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.

Ben 10: Ultimate Alien
Chromastone briefly appeared in the Ben 10: Ultimate Alien episode, Fame, facing Bivalvan only to be electrocuted at the end. Also, in the episode Video Games, Ben tried to turn into him but for some strange reason turned into Swampfire.
