Freddy Krueger biography:
"A malevolent spirit of the Dream Realm, Freddy Krueger preys on the souls of the living as they sleep. When Shao Kahn began to steal Earthrealm's souls - souls Freddy considered his own - Freddy battled the emperor in the Dream Realm. But Shao Kahn's will was too strong. He pulled Freddy into the real world, where he was mortal, and defeated him. A badly injured yet determined Freddy fitted both his hands with demonically enhanced razor gloves. Once he has killed Shao Kahn he will find a way back to the Dream Realm, where he will torment Earthrealm's souls for eternity."
