Hmm... My character would be pretty interesting.
He would be dressed in a nice brown fedora with ridges in the brim, a black jacket with a sort of whitish-gray collar (never zipped up), a t-shirt which, with every new session has a different smart-ass remark randomly generated on it, blue jeans that are only ripped up closer to the feet, and either solid black tennis shoes or solid black slip-ons. As for interaction with other characters and the environment... Every time the horde rushes the group, my character would mutter "Oh buggery" in what he thinks is a good British accent. Every time a team-mate sets the horde off or gets caught by one of the special zombies (especially the Smoker), my character will shout "Nice going Cpt. Oblivious!" or "You fucktard!". When my character heals himself he will say "Wait up guys, just give me sec... Oh crap, is that SUPPOSED to be at that angle?", when my character is healing a male team mate he will say "Oh fine then", when healing a female team mate he will say "Sure thing!". When saving a male team mate, he'll say "You owe me for this, you heavy bastard", when saving a female team mate, he will say "Don't worry, I've gotcha." When dying, being surrounded by the horde, being caught by the hunter/smoker, or being attacked by the witch/tank, he will shout "OHSHITOHSHITOHSHIT I'M GONNA DIE!!!!". When simply talking to team mates while waiting around (like say, in the elevator), he will exchange smart-ass insults with the guys, and nervously flirt with/woo the girls. Yes, I know myself THAT well.
