Recently I had the displeasure to run across what I believe to be the most evil enemy to ever appear in a video game: the Death Slime from Wizardry Empire: Fukkatsu no Tsue (Staff of Restoration) on Gameboy Color. What makes it so bad? It can PERMANENTLY drain 99 levels of experience from any of your player characters with a single blow. There is no way to reverse it either, once those levels are gone, they're gone--hours and hours of work straight down the drain. The only thing that could be conceivably worse would be an enemy that could erase your save file. Did I mention that it has a -20 AC and 90-100% magic resistance, which makes it nearly impossible to hit, and that it can poison, paralyze, petrify, and decapitate you, all at once, on top of the level drain?
