He has his original series appearance, but his colors match the color palette of Heroes United. He wears a green and black tunic and his eyes are green. The Infinimatrix symbol is on his chest, recolored black and green.
Ben slams down the Infinimatrix's dial and is engulfed in a green light.
Ben hovers in a dark green background, with light green bubbles pulsating rapidly behind him, as he crouches down. His skeletal structure decreases greatly, condensing Ben's body to six inches. His eyes become circular and his pupils expand, taking on a rectangular shape. His hair disappears as his skin turns grey. His head changes shape, his nose disappears and a black stripe appears in between his eyes. His ring and pinky fingers merge into one, and his toes merge into three. The Infinimatrix symbol pops out of his chest. Grey Matter crosses his arms and grins, completing the transformation.
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, (such as a warp-drive engine). 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 appears to be stronger than he looks.
Grey Matter is amphibious and has gills.
Grey Matter has a long prehensile tongue, owing to his insectivore nature. As a Galvan, he also possesses a 'pre-brain' which deals with all basic bodily functions.
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 a chew toy or food to them.
