Ultimate Grey Matter is the Ultimatrix's DNA sample of an Evolved Galvan from the planet Galvan Prime.


Be afraid of this nightmarish genius! Ultimate Grey Matter increased his height, giving him the strength to go toe to toe with other alien species. He also get the ability to secrete cerebrospinal fluid which harden into weapons.


His devolved form looks identical to Neon's, except the green parts are red and his skin is slightly tinted red.

Ultimate Grey Matter is a red-skinned, frog/demon-like, bipedal alien that is significantly taller than Grey Matter. His limbs and fingers are long and slender, with his fingers having claws. Unlike Grey Matter's feet, he has two front toes and one back toe on each foot, which are also pointy. He has large glowing red eyes with minus-shaped pupils. On his head there are 4 horn growths. He wears a grey vest over a black sleeveless jumpsuit with black markings.

He wears the Ultimatrix symbol on his back.

Powers & Abilities

He can shoot dark red fireballs from his hands that encase enemies in a red crystal-like substance.

Dark Matter can secrete a dark red cerebrospinal fluid, which he can harden into a plaque and manipulate it to form weapons resembling the red crystal produced from his fireballs.

Can climb on walls.

Can breathe underwater.

Has sharp teeth.

Has a prehensile tongue.

Has super intelligence.


His larger size makes him easier to hit than a standard Galvan.

There is a limited extent in how much damage his crystal traps and weapons can take before cracking or shattering.


  • His design is based on Dark Matter from the Ben 10 Reboot.
