Chinese clan
In "Mortal Kombat" (1992), it is established that a series of Mortal Kombat tournaments are being held to determine if the forces of Outworld will be permitted by the Elder Gods to invade and conquer the dimension of Earthrealm. The game takes place during the tenth and final tournament, hosted by the shape-shifter sorcerer Shang Tsung, who is a servant of the Outworld emperor Shao Kahn. In the original game, it is implied Scorpion has enmity towards Sub-Zero due to rivalry between their opposing warrior clans (Scorpion's Japanese clan is unnamed, while the game names Sub-Zero's Chinese clan "Lin Kuei"). Scorpion's ending reveals he is actually an undead specter, a warrior who was killed by Sub-Zero, survived by a wife and child, and allowed to return to the physical realms in order to have his revenge. The same ending implies that the curse of Scorpion's supernatural existence means he can have revenge but can't reunite with his still-living family. Canonically, after the tenth tournament is won by the human champion Liu Kang, Scorpion kills Sub-Zero.
