Here comes Grey Matter one of Ben 10. Grey Matter is a gray-skinned, frog-like, bipedal alien only five inches tall. His size allows him to squeeze into small spaces, and he can climb walls because of the tiny suction cups on his skin. He also has sharp teeth, and his slimy skin makes him difficult to grab. However, his size makes him unsuited for battle. So, Ben 10 must outsmart his enemies while using the form, but Ben doesn’t need to worry because by transforming into this form, 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. Cool enough, isn’t it ?
