Extremely old character of mine, from when I was 16-ish, now redesigned. I had an ill-fated webcomic on Gaia Online, and this guy was the titular character.

Bob, short for "Bobelzebob" (his parents were not good at spelling) lives in Pandemonium, kingdom of the demons. He is an imp, the lowest rung of demon society, suitable only for manual labour and getting beaten up for amusement.

He's rather cheerful and energetic, and has a very undemonic optimism. Traditionally when an imp is born they are thrown very hard at a wall to introduce them to the realities of this sick sad world, and get a sign of how they would react to troubles in future life (either with silent stoicism or by breaking down in tears, usually). Bob bounced.

(Oh, you may notice his design looks familiar. Well, I was 16 and really into Digimon. Yes, you're thinking of Impmon. I like to think his design is sufficiently different to not be TOO bad though.)
