– Chromastone to a zombified Lucy.[2]

Chromastone (alternatively spelled as ChromaStone)[3] is the Omnitrix's DNA sample of a Crystalsapien from the planet Petropia.


Chromastone is a silicon-based alien made of extremely durable crystal. His body is overall indigo, with several dark lines and spots. His hands and face are magenta, and he also sports six magenta shards on his back, two on his chest, and one on the top of his head that resembles a horn. His face consists of a mouth and one large green eye at the center.

In Alien Force and Ultimate Alien, Chromastone wore the original Omnitrix/Ultimatrix on his chest.

In Heroes United, Chromastone had green teeth and some of his dark lines were missing.

In Omniverse, Chromastone has two unique designs. The first, which appears in Trouble Helix, looked mostly the same as in Alien Force and Ultimate Alien except that the crystals on his back and head were much longer. Much like before, the Omnitrix symbol is on his chest.

The second design, which appeared in A New Dawn, is drastically different. He has three additional crystal shards on each shoulder and arm, one on each knee, and two on the sides of his head. The crystals on his chest and the four small shards on his back are gone. His neck is now longer, his face has a magenta chin that resembles a mouth guard, and he now speaks without moving his mouth at all. He has five fingers on his hands. He now wears a green jumpsuit with white stripes on the waist, green-and-white striped gauntlets on his wrists and legs, and the Omnitrix symbol has been relocated to his right pectoral.

Powers and Abilities

Chromastone has the ability to allow many types of energy, such as lasers, electricity, mana,[4][5][6] and radiation[MW 1] to phase through his body without harm.

Chromastone can absorb and channel energy into ultraviolet beams powerful enough to melt through a truck trailer[7] and destroy an entire turret.[8] He can fire these beams from either his hands or from the nine shards on his body and can project these beams as either energy blasts or projectiles. He can even absorb big stars like Rigel.[DR 1]

Chromastone can control the intensity of his energy attacks, and the amount of power his ultraviolet beams have depends on how powerful the energy from an opponent's attack is. For instance, when the Dragon attacked Chromastone with its powerful energy blast, the latter absorbed it and subdued the Dragon with a powerful wave of ultraviolet energy.[9] Similarly, when Gwen gave Chromastone a large amount of mana for him to absorb, he was able to shoot powerful energy blasts at Dagon.[6]

Chromastone is able to allow energy attacks to simply bounce off his body instead of absorbing them.[10]

Chromastone can free himself from mana force fields simply by touching them (absorbing the mana).[5] He can also produce energy shields of his own for extra defense.[6]

Chromastone can use his energy to dissolve an Arachnichimp's webs should he be ensnared by them.[11]

As well as being immune to electricity, Chromastone can also conduct it back at the attacker, as seen when Lucy attacked him with an electric cable.[2]

Chromastone can project a beam of light from his hands for illumination purposes.[7] He can also shoot his energy blasts without absorbing anything, but only to a limited extent.[6]

Chromastone is capable of jumping exceptionally high.[12]

Chromastone possesses enhanced durability thanks to his very dense and crystalline skin,[merch 1] which allows him to withstand being thrown against several vehicles at once.[10]

Chromastone possesses enhanced strength, allowing him to overpower stronger opponents, such as a Techadon-enhanced Cash, with his bare hands.[10] Technically speaking, he is physically stronger than Methanosians.[DM 2]

Chromastone is capable of flight,[13] and can leave behind an ultraviolet energy trail while flying.[14]

Due to him being made of silicon-based crystals, Chromastone is immune to a Xenocite merging with him.[7]

Chromastone can survive in the vacuum of space, as demonstrated by Sugilite when he was traveling to what was left of Petropia.[1]

If a big enough light source were to shine through him, Chromastone can create a big, beautiful rainbow in the sky.[DJW 1]


Although Chromastone is highly durable, he is not completely indestructible, as he can be shattered by extreme force, such as when he was destroyed by Vilgax using his sword.[4]

Chromastone is unable to absorb energy when he is either not expecting it or too weak to do so. He is also unable to absorb electricity while it is being conducted by water.[15]

Chromastone has a limit to how much energy he can absorb at once, as he once tried to absorb all the mana energy of Charmcaster's machine but was overwhelmed to the point of almost crumbling apart.[14]

In addition to Chromastone having a limit to how much mana he can absorb, he also cannot absorb the energy released by an Annihilargh because he would be instantly disintegrated if he tried.[DJW 2]

Magic can harm Chromastone, as shown when he was incapacitated by two of Gwen's spells.[5]

Chromastone's ultraviolet beams are ineffective against Vilgax's sword[4] and the extra-dimensional field of the Contumelia's machine.[16] They can also be absorbed by a Conductoid.[DJW 3]

Despite his enhanced strength, there is a limit to how strong Chromastone is, as seen when he failed to punch through the Contumelia's machine's extra-dimensional barrier.[16] Technically speaking, Chromastone is physically weaker than Vaxasaurians.[DM 2]

Chromastone can be controlled by Vladats via their Corrupturas.[DJW 4]

Chromastone cannot absorb gooey substances, such as the plasma generated by members of Ball Weevil's species.[DJW 5]

Chromastone is a playable alien character in the Nintendo DS version of the game.

Chromastone is initially unavailable, but is unlocked at the beginning of the Cave 3-1 level.

Chromastone is able to shoot ultraviolet energy beams of varying intensity and width, as well as unleash an omnidirectional blast of ultraviolet energy which stuns all enemies.

Chromastone is not required to be used at all in order to complete the game.

Ben 10 Alien Force: Vilgax Attacks

Chromastone is a playable alien character in the game.

Chromastone is capable of manipulating the energy into bolts, rather than beams, as well as generating an energy blast expanding out in a 360-degree radius, creating an energy shield, and wielding energy fists.

Xbox 360, Nintendo Wii, PlayStation 2, and PlayStation Portable Versions

Due to the Omnitrix rebooting after Ben's abuse of the quick-change feature during his battle with an animated Mr. Smoothy mascot, Chromastone was temporarily locked until Ben's arrival on Mor' Otesi.

Chromastone is able to channel ultraviolet beams to power lifts for transportation and machinery to access locked areas.

Similar to Brainstorm, Chromastone's unique block animation summons a shield made out of ultraviolet energy that renders him impervious to energy attacks.

Prismatic Explosion is an unlockable combo move for Chromastone.

Chromastone is vital for progression on the Mor' Otesi level of the game.

Chromastone was erroneously designed with four magenta shards on his back when there is supposed to be six of them.

Nintendo DS Version

Chromastone is able to safely bypass the radioactive meteors that litter Mor' Otesi's landscape.

Ben 10 Alien Force: The Rise of Hex

Chromastone is a playable alien character in the game.

Due to the Omnitrix sorting out after Ben fiddled with it, Chromastone was temporarily locked until the beginning of Level 8.

Chromastone is able to absorb energy from a solar cell and store it inside him, transferring it to other cells in order to open sealed gates or to activate moving platforms. Chromastone can retain this stored energy even if he reverts back to human form and/or he switches to other alien forms.

Chromastone's hard crystalline body makes him immune to physical attacks. Whenever he is hit, his Omnitrix Energy meter instead of his health meter will be depleted.

Ben 10 Ultimate Alien: Cosmic Destruction

Chromastone briefly appears as a hologram in the game, but is not playable.

Chromastone's name is a combination of the words "chroma" and "stone".

Chroma means purity or intensity of color, noting the intensity of the color in Chromastone's rays and stone. Stone is the nonmetallic mineral that a rock is made of, referencing his appearance.


  • Chromastone had concept art drawn by Glenn Wong and Eric Canete, whereas his final design was created by Chap Yaep, with color styling by Chris Hooten.[GW 1]
  • Chromastone is one of the four regular aliens to get a complete redesign in Omniverse; the others being Shocksquatch, Eatle, and Swampfire. However, Chromastone and Swampfire are the only two of these aliens to get redesigns mid-series (not counting Rath getting clothes).
    • The area behind Chromastone's eye was originally going to be black, just like his rendition in Alien Force and Ultimate Alien.[DJW 6]
    • Chromastone's design in A New Dawn is inspired by Gundam.[DJW 7]
  • Chromastone only appeared in two episodes of Omniverse due to his low toy sales during the previous shows' runs.[DJW 8]
  • Chromastone is one of the five aliens who escaped from the original Omnitrix; the others being Ghostfreak, Goop, Way Big, and Spidermonkey.
    • Chromastone is also one of four regular aliens to be temporarily destroyed and removed from the original Omnitrix/Ultimatrix, the others being Way Big, Swampfire, and Feedback.
  • It has been stated by Tetrax that Chromastone has more abilities than the ones Ben is aware of.[1] However, they are largely unexplored.
  • Chromastone's reformation into Diamondhead in Vengeance of Vilgax: Part 2 had nothing to do with Vilgax's sword being covered in crystal before he destroyed him.[DM 3]
    • Ben does not know the explanation behind Chromastone's reformation, but Azmuth does.[DM 4]
  • Chromastone and Sugilite are the only Crystalsapiens in existence.[DM 1]
  • Chromastone is the final alien used on-screen in Ultimate Alien. Coincidentally, his hologram is also the first one shown on the recalibrated Omnitrix in Alien Force.[17]
