Kitana's first appearance was in the second Mortal Kombat tournament. She was introduced as Shao Kahn's daughter and personal assassin. Her true feelings and alignment were a mystery, though they were revealed to the Earthrealm warriors during the tournament. She was not really the daughter of Shao Kahn, but in fact his stepdaughter; she was adopted by Kahn, as an infant, to strengthen his claims to the Edenian throne after he killed its king, Jerrod, and married Jerrod's wife, Queen Sindel, who were Kitana's parents. Suspecting she would someday learn the truth, however, Kahn instructed Shang Tsung to create a twin for Kitana; the monstrous Mileena, who was actually a grotesque and evil clone of Kitana.
