Chromastone

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

Ben first transformed into Chromastone in the episode All That Glitters when fighting a horde of zombified schoolgirls(this was also the episode when Kevin got jealous of Michael Morningstar).

Appearance
Chromastone is a silicon-based lifeform made of highly durable crystal(like Diamond Head).He has a purple body, 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: 6 on his back, 2 on his chest, and one on top of his small, purple head, resembling a horn. He also has one, large, cyclopian eye. Chromostone's name actually comes from the word 'chromosome' which means 'color'

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. Since it is the only one who can restore Petropia's people, it's DNA must have Diamondhead's DNA so that is why it turned it into Diamondhead. In The Secret of Chromastone, Tetrax used a seismic weapon to shatter Diamondhead's crystalline structure, exposing Chromastone underneath. Tetrax then gave Chromastone 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 Chromastone 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.

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.

Weakness
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 still get electrocuted when wet.

Based on
Chromostone is based on Diamondhead mostly. Both are nearly indestructible, are partially/wholly made of crystal, can absorb and/or redirect energy. His name is also probably based on the word 'chroma' which means 'color'.

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 and the same appearance as Alien Force.

Trivia

 * Chromastone's name comes from the words Chroma (meaning Color in Greek) and Stone. So, translated, his name would mean "Color rock", referring to his powers.
 * Chromastone's DNA sample came from Sugilite, the Guardian of Petropia and serves as his genetic back-up.
 * It is revealed in The Secret of Chromastone that Chromastone is still inside the Omnitrix.
 * In Fame, Ben wasn't even sure that he still had Chromastone, even though he now has the Ultimatrix.
 * When Ben becomes Chromastone he always poses dramatically, except for his first appearance.
 * The name Chromastone is similar to Chromosome for the reference that he is the back up key for the revival of Petropia and the Petrosapiens.
 * Chromastone is indestructible hence it will turn into a Petrosapien when damaged and vice versa.
 * Ben is shown to not fully know Chromastone's powers, as he did not have access to certain powers that Sugilite possess.
 * Chromastone's transformation is similar to Diamondhead's Alien Force transformation.
 * The energy beams that Chromastone shoots change in appearance and colors occasionally in different episodes.
 * Although out for practically all of season 3 of Alien Force, he still has appeared only once briefly since Ultimate Alien.
