Matter the Grey

Here is a villain for Doc Stalwart to match mindpower with... because he's only got mindpower. Because he's a brain. In a jar.

I present to you... Matter the Grey. 

I have no idea what I'm going to do to make this different than all the other brain in a jar villains, but I'll think of something. For now, I'm just knocking out some illustrations, and I'll worry about how this all fits together at some point soon :)
