Ben 10, Bakugan and Eddsworld: All Series: Grey Matter

Species: Galvan

Planet: Galvan Prime

Description: Grey Matter is a gray-skinned, frog-like,bipedal alien only five inches tall; however, his size belies his intellect, which is second to none. He can create almost anything from spare parts and deduce the function of any device at a glance. This ability extends to organic organisms also, determining the position of nerve clusters under the skin of an alien creature he'd never seen before. His 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. However, Grey Matter's size makes him unsuited for battle, and hence Ben must outsmart his enemies while using the form. Showing a more light-hearted side of the Omnitrix, Ben, despite being able to understand any device, does not consciously comprehend what he is doing, leading him to remark as such.
