Grey Matter is a grey skinned, frog-like, bipedal alien that is only 5 inches tall. He has large orange eyes, with rectangular pupils. He wears a green jumpsuit with a black stripe going down the middle of the chest, which connects to black rings around his neck and waist, black rings around his wrists, and black coloring from the knees down.
Grey Matter wears the Omnitrix symbol on his back.
Powers and Abilities
Grey Matter's small size belies his great calculative and technical intellect. He can create complicated machines from spare parts, understand the function of any device at a glance, and make sophisticated repairs to complex machines. Grey Matter's intellect serves as a problem solver and analytical help in difficult situations. This allows Grey Matter to think more strategically when brute force is inefficient.
Grey Matter can sometimes manipulate living things by stimulating certain parts of their nervous system, if such beings can be controlled by external stimuli.
Grey Matter's size allows him to squeeze into small spaces and can climb walls due to tiny suction cups on his skin. He also has sharp teeth and his slimy skin makes him difficult to grab.
Grey Matter is amphibious and has gills.
Grey Matter's small size makes him ill-suited for physical battle, so he must outsmart his enemies in a fight. Animals like dogs and cats can be a problem, as they may see Grey Matter as a chew toy or food to them.
