Alright, I did these images for something else, and they're kinda quick and dirty, but I'll toss'em here for lack of a better place to put them. They all for a superhero game I'm running - these are supervillain inmates, superhero characters, and assorted other filler people.

Villians:

Crankshaft
Endless
Octave
Octopus
Thud
Ubermind
Wall

Heroes:

Arsenal
Keen Teens
Captain Heroic (and Wonderlad!)

Other Guys:

Warden Collins
Dr. McAllister
Generic Guard

I'll let you go ahead and guess what everyone's powers are.
