Mortal Kombat 2

The hell-spawned spectre rises from the pits. After learning of Sub-Zero's return, he again stalks the ninja assassin - following him into the dark realm of the Outworld where he continues his own unholy mission.

Upon learning of Sub-Zero's reappearance, Scorpion enters Shao Kahn's tournament. He witnesses Sub-Zero spare the life of an opponent and realises that this is not the same Sub-Zero who murdered him so long ago. He lets the ninja live and goes on to defeat the Outworlders in their unholy contest. With the defeat of Shao Kahn, he discovers a new purpose for his existence. He becomes the guardian of the new Sub-Zero to atone for murdering his older brother.
