Ben 10 - Grey Matter

Grey Matter is one of Ben's smallest alien forms. It may look like he's pretty weak, but he's actually pretty strong. He can climb on walls even. He can also be hilarious sometimes. In one episode, when Ben wants to become Raths, but becomes Grey Matter instead with his new Omnitrix, he says "Grey Matter?! Man, I have got to get a manual for this thing!"

His species is a Galvin. They are not just called Galvins, but they live on a planet called Galvin. Their moon's name is Galvin-B. The Galvinic Mechamorphs lived there, but they are pretty much all extinct. Galvanic Mechamorphs are creatures made out of energy from a thing called a Helix. There is only one left. His name is Malware and he's evil.
