Mileena is a mutant hybrid clone of the Edenian princess, Kitana, created by the sorcerer Shang Tsung. She is one of the adopted daughters of the Outworld Emperor Shao Kahn and serves as one of his personal enforcers. As an antagonist, she is known for her vicious, unstable, and unpredictable nature, a stark contrast to the composed demeanor of her 'sister,' Kitana. Her hybrid nature often manifests in a grotesque, Tarkatan-like mouth which she usually conceals.
