Degenerate descends of the Ascii tribe, the empty-eyed, blank-faced mundanes were just like zombies, except they were not dead. The Ascii un-undead were merely living human beings who chose to pursue this numbing lifestyle. Once soldiers, the Ascii as mundanes were no longer very skillful at combat and mass hordes could be easily defeated by a single combatant.

During the days of the Autoexec's betrayal, he used legions of these mundanes in an attempt to stop his enemies--Glorian, Mirakles and Spike. All of the un-undead soldiers in his army were defeated.
