Once, you were part of the mortal kombat arena and it was brutal to fight many warriors in outworld, and many other realms. In one battle, come face to face with Shan zhun creations: mileena. She may look like katara, but she’s got barakas dna.

After some talking, (and near evasion from her attempts to eat you) you both fell in love and got married.

You brought her to earth realm and soon she started to get use living here with you. (Well… almost)
