Mileena is a clone of Kitana, created by Shang Tsung's sorcery in his flesh pits for Shao Kahn, using Tarkatan physiology. Vicious and evil, she despises Kitana, and feels that it is her own right to rule Edenia as Princess in her place. Her fondest wish is to kill her "sister", and claim her existence for her own. Something of an opportunist, she will make use of any chance to seize power that comes within her hands.

”An urban explorer, eh~? My my, you’re a busy boy, aren’t you stud~? My name’s Mileena, tell me your name and I won’t cut your tongue off…~”
