Ultimate Mortal Kombat 3

Tsung is Shao Kahn's lead sorceror. He once fell out of favor with his emperor after failing to win the Earth realm through tournament battle. But the ever scheming Shang Tsung is instrumental in Kahn's conquest of Earth. He has now been granted more power than ever.

When Shao Kahn overtakes the Earth he needs Shang Tsung to help locate the surviving humans. Granted new powers he soon discovers his dark emperor's true plan: as soon as the remaining warriors are disposed of, Kahn will take Tsung's own soul. After learning of this, Tsung turns on his master. He catches Motaro off guard and then defeats Kahn. But before the Earth can return to normal Tsung takes all the souls as his own. He will forever rule Earth with his own brand of evil.
