Mortal Kombat: Defenders of the Realm - Season 1 - Eps 8: The Secret of Quan Chi
Quan Chi finds a magic crystal with which he is able to awaken all the evil in a human soul. Using it, the magician influences on Earth Warriors and makes them hate each other. The Earth is now out of any defence, and would be conquered by Quan Chi, if not for Nightwolf who escaped the crystal's influence. It's Nightwolf who's fate is to destruct evil crystal and to ruin Quan Chi's black magic.
