She is a character in the Mortal Kombat game series.
She was brought to life by Shang Tsung using Tarkatan's race physiology to be a clone of Edenian Princess Kitana.
When her mask is on, she looks similar to Kitana, since Kitana also wears a mask. However, when it is off her visage is exposed.
She is the arch-enemy of Kitana. Her main goal is to kill Kitana, her "sister", and rule Edenia as a princess in her own right.
