[@Lady Selune]I used [url=heromachine.com]Heromachine 3.[/url] It uses a parts-based system that's kind-of drag-and-drop to let you build characters. They've got parts from all sorts of different genres, and even actual stuff from Fallout/Star Wars and other universes. It's a really handy tool, I use it all the time when art/images for concepts in my head don't exist.
