Freddy Krueger- "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."
Kratos-"Ancient Greece knew no more bloodthirsty warrior than Kratos, who for a time was the God of War. Mortal once more, Kratos withdrew from the ages-old clash between men and gods. But his solitude was broken when he was ripped through space and time. As the madness subsided, Kratos found himself in present-day Outworld, kneeling before Shao Kahn. To ensure his victory in Mortal Kombat, the emperor had invoked an ancient ritual, sacrificing the souls of his vanguard to summon and enslave the most powerful warrior of all time. But the spell alone could not contain Kratos, who soon regained his free will. Enraged by Shao Kahn's arrogance, Kratos vowed to rip the warlord's spine from his body. The God of War had returned to battle."
