Appearance
He is a Galvan, a gray frog-like alien that is five inches tall. The Galvans are a highly intelligent race responsible for many of the technologies shown in the series, including the Omnitrix, the Null Void Projector, the Null Void, their planet, Galvan Mark II (since the Highbreed destroyed their original homeworld, Galvan Prime, in the "Alien Force" two-parter "War of the Worlds"), and the Galvanic Mechamorphs (Upgrade's species).
Powers and Abilities
- Enhanced Agility: Due to his small size, Grey Matter is easily able to dodge attacks.
- Wall Crawling: Grey Matter can climb up vertical slopes with ease.
- Underwater Breathing: Grey Matter has gills which allow him to survive underwater.
- Manipulation: Through his opponent's pressure points, Grey Matter is able to manipulate their body into doing what he wants. He has used this ability on creatures such as sharks and Null Void Guardians.
- Hephaestan Neuro Grip: Using this technique Grey Matter can incapacitate "all manner of prey".
- Enhanced Intelligence: Grey Matter's species is one of the smartest in the galaxy. A notable of this intelligence is when he was able to easily shut down a machine that could affect climate change and make it snow all year in the desert, manipulate a person's nervous system, mutate children into elves, grant reindeer flight capabilities, control dozens of guards and manipulate the fabric of time itself all at once.
- Enhanced Reflexes: Grey Matter was able to jump off the 'Test your Strength' machine just as the platform hit the bell.
- Technological Prowess: Grey Matter was able to invent a "sun gun" with only a few scraps and a few minutes.
