Fatality

Fatality is no hero; she's actually a supervillain from the DC Comics Universe and sworn enemy of Green Lantern. Green Lantern accidentally destroyed her planet and Fatality was the sole survivor. She came to Earth to exact her revenge but didn't know the identity of Green Lantern, so she tried to kill every Green Lantern she came across. In one of her battles she was presumed dead after her severed arm was found, but no trace of her body was discovered. She resurfaced later with a prosthetic arm attempting to even the score and lost her other arm. She is very skilled in combat and has a mastery of most weapons. She uses a power rod most of the time and a yellow Qwardian ring, which happens to be among the Green Lantern's weaknesses.
