Dubbed by the press as "the most dangerous woman who ever lived." All that is really known about Slaughter is that she was fast, powerful and completely without mercy: she very rarely left survivors. Slaughter's public appearances were few, but they were memorable: on one occasion - for reasons still unknown - she attacked a scientific research facility in New Mexico, killed everyone present and completely tore the building apart with her bare hands. Though not actually invulnerable, Slaughter seemed to possess a tremendous stamina and would fight on long after anyone else had given up.

Costume:
Slaughter usually wore a blood-red skin-tight costume, though at times she was seen to wear a blue costume with blue boots and gloves; this has led many people to believe that more than one super-villain used the name.
