Peron

Peron, Scorpion's sidekick and possible wife is also introduced and appears only in the 15th episode of Mortal Kombat: Conquest. It is also seen that she is very skilled in the art of Kombat and assassination. Actually, she is the one who killed Sub Zero's younger sister, impaling her back with a knife. Sub Zero, after seeing this, grabs Peron by her neck and freezes her to the death, let ´´her´´ go and she breaks.
