Quite a few! They're just all for tabletop RPGs so I don't talk about them here.
Tabletop!
Counting all the campaigns I'm currently in... I have eight that I've developed and played enough to really call full-fledged characters.
Though I suppose teeechnically seven since two of them are the same person. :3
That campaign is over now and man was it fun to reveal that timey-wimey mess to the other players.
Right now, my most fun character is definitely from the Steampunk setting. His name is Pathfinder! He is an airship pilot.
With a (horribly performed by me) southern accent.
I always have to drink a little before I play him, but he's a dick and the most hilarious thing I have in my roster. Don't ask him about the panty incident. xD
