2. Freddy Krueger (Nightmare On Elm Street)
Freddy Krueger is the worst undead killer in horror movie history. Hes a horrible individual, who in life was a paedophile and child killer, and was killed by a mob of angry local parents who became aware of his disgusting deeds. However, the fearful reputation he developed gave him the power to haunt childrens nightmares even after his death, which subsequently gave him control over their dreams and the terrifying ability to kill them in their dreams while they slept. He has been the subject of several nightmares in the real world since his first movie 1984s A Nightmare on Elm Street and is generally considered to be the ultimate horror icon. Whether its is super-powered, reality-warping dream self or his knived-fingered and horrifically burned real world self, Freddie would make for an horrific Black Lantern Corps member. Combining the powers of a black ring with his dream powers would make him nigh-unstoppable.
