Mordo the Spaz (careful! He who laughs at Mordo the Spaz soon eats Aimlessly Flailing Death!) was a berserker, created under the (IIRC) "Unearthed Arcana" ruleset. He was true to his calling, as well - when he received a cursed sword, whose curse was that it must be used to destroy a living or unliving being within 10 minutes of being drawn (if not, the wielder would go berserk on the nearest possible target; if alone, he would berserk on *himself*), Mordo didn't see the problem. I've always said that Mordo died as he had lived - in an orgy of mindless violence. :-)
