Eh, I have one idea I'd probably do for an ongoing, and another I'd do for two or three graphic novels. My graphic novel idea would revolve around a character I created,

When I first came up with his story, it started out as a cut-and-dried superhero-vs.-supervillains adventure and he looked more robotic, but lately I've been rethinking it into an alien invasion/mutation story inspired by the movies that came out when I was younger, mostly from the remade versions of Body Snatchers ('78), The Thing, The Fly, Invaders From Mars and Village of the Damned, with a touch of Verhoeven's Robocop (poignant in a few moments, funny-in-a-really-nasty-way in most others) thrown in.
