 Grey Matter is a Galvan from the planet Galvan Prime. Ben first used him in The Filth, where he watched some cartoons in a box before getting interrupted. He is voiced by Todd Haberkorn. Grey Matter and Four Arms fused in the episode Riding the Storm Out, resulting in Grey Arms.

Appearance

Grey Matter is a small, frog-like humanoid with grey skin and three toed feet. He has four fingers, a green jumpsuit with black stripes and large orange eyes with black slits as pupils. He has a black stripe going over his head and has what appears to be gills on his cheeks. Unlike most aliens in Ben 10, the Omnitrix symbol is located on his back.

Omni-Enhanced Grey Matter wears a frog-like battle suit made out of grey rocks. He has two cube-shaped shoulder pads, long blue plasma arms with wristbands and three fingers, as well as green moss on his shoulder pads and neck. The Omnitrix symbol is now located on his chest.

Powers and Abilities

Due to Grey Matter's small size, it allows him to fit into spaces that most other alien forms can't. He can be used to sneak into areas and is very fast and agile. He can jump very high and stick onto walls. Grey Matter's main ability is his great intellect, which is reflected by the way he speaks. Using his wide range of knowledge, he can rewire machines to turn them into a weapon and repair complex hardware. 

Grey Matter can also manipulate certain living beings by stimulating certain parts of their nervous system, ranging from stunning the being to changing its direction when its walking. Due to his gills, Grey Matter can breathe underwater.

Omni-Enhanced Grey Matter is more suited for combat. He has stretchy limbs that are able to electrocute opponents and his feet allows him to jump higher.

Weaknesses

Grey Matter's small size and weak strength makes him unable to fight larger foes, so he must outsmart them or hide.
