My longest-running PC was a Human Barbarian. He was quick with a (crude, earthy) joke, quicker with booze, loyal unto death towards his friends, unspeakably savage towards his enemies (I'll never forget that first Critical Hit he made...split a dire boar in half, lengthwise!), confused and therefore irritable with the seemingly-arbitrary rules of "civilized" areas (What do you mean, he's chosen a champion to duel me on his behalf? Why can't the magistrate fight his own battles?) and prone to finding straight-forward solutions to problems -- a villainous spellcaster summons a fiendish boar in front of me? I pick it up by the tusks, swing it around and throw it back at him!
