First Appearance: Daredevil (vol. 1) #320 (Sep. 1993): "Fall from Grace: Part I"
Super? (Has Super Powers/Special Abilities/Technology): Yes
Number of Appearances: 4
Enemy of: Daredevil
Note: corpse reanimated by Snakeroot and the Hand
Erynys was a corpse a dead woman that was re-animated by mystical ninjas of the Ninja sects Snakeroot and the Hand. These evil ninjas used Erynys as a warrior to battle their enemies, including Daredevil.
The ninjas instilled Erynys with the dark essence of Elektra (Daredevil's former lover and a former member of the Hand). They distilled this dark essence from the mind of SHIELD agent John Garrett, who had a complicated history with Elektra.
Ultimately, Erynys was killed -- as shown in Daredevil (vol. 1) #325 -- but its dark essence corrupted the resurrected Elektra.
