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. Additionally, he 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.

Grey Matter appears to be stronger then he looks, as he was strong enough to move a cleaner's bucket with mops in it in Ultimate Weapon.

Weaknesses
Grey Matter's size makes him unsuitable for battle, so he must outsmart his enemies in a fight.
Animals like dogs can pose a problem, as they may see Grey Matter as food or a toy.
