20. Mr. Zzasz
First appearance "Batman: Shadow of the Bat" #1 (1992)
Created by Alan Grant and Norm Breyfogle
Mr. Zzasz is one of Batman's most disturbing foes in that he is simply a lunatic with a knife, a desire for blood and no moral consciousness whatsoever. Zzasz's trademark is carving a tally mark into his own body after each kill, a character perversion that separates him from the pack of other literary serial killers. He does not kill for profit or power -- only for fun. Like Henry Lee Lucas or Richard Speck, Zzasz is a modern nightmare, a killer lurking in the shadows with an insatiable need to feed his own dark appetites. Worse of all, Zzasz is almost a mental match for Batman. Gotham's dark tally man is a killer with a brilliant mind ready to carve the city's denizens into pieces to suit his own perverted desires. There are some terrifying monsters on this list, but Zzasz may just be the most monstrously human of them all.
