Appearance[]
11 Year old Grey Matter
In Omniverse, 11 year old Grey Matter looks exactly the same as the original, but he has a much longer neck and his costumes collar is now black. His skin tone is also different.
16 year old Grey Matter now has a green jumpsuit with a black belt, his collar is now black, and the Omnitrix symbol is on his back.
Powers and Abilities[]
Grey Matter's size belies his great calculative and technical intellect. He can create almost anything from spare parts and know the function of any device at a glance. Grey Matter's intellect serves as a problem solver and analytical help in difficult situations.
Grey Matter can sometimes manipulate living things by stimulating certain parts of their anatomy, if such beings can be controlled by external stimuli.
Grey Matter's size allows him to squeeze into small spaces and he can climb walls thanks to tiny suction cups on his skin. He also has sharp teeth and his slimy skin makes him difficult to grab.
According to Derrick, Grey Matter is amphibious and has gills.
Weaknesses[]
Grey Matter's small size makes him unsuitable 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 food or toy.
