Powers and Abilities
Grey Matter’s main (and only) power is intelligence. As he has little to no physical ability (save for sharp teeth) he relies on his intellect to outsmart his enemies. He possesses enough intelligence to work advanced machines and build highly advanced weapons. Likewise, the mucus his skin secretes allows him to adhere to surfaces to climb them.
