A variant of the Jokester is the Troublemaker. This is the character who tries to steal from the party, or goes off on his own in town or the dungeon and gets himself in a fix, or makes stupid decisions on purpose that ruin the party's plans or otherwise makes things more difficult than they need to be. Troublemakers invariably leave the party (alive or otherwise) before too long, but new Troublemakers always seem to crop up.
