Princess Kitana is 10,000 years old, but is considered young in her realm of Edenia and has the appearance of a young woman. Throughout the years, she rose to great importance; first as the loyal stepdaughter of Shao Kahn, then as his enemy, tearing herself away from his grasp and freeing her home realm of Edenia. She also led an army into Outworld to combat any chance of Shao Kahn rising to power again.
She shared a subtle love interest with Mortal Kombat champion Liu Kang, even after he was murdered by the Deadly Alliance. Although she was loyal to Shao Kahn for most of her life, she eventually betrayed him and aligned herself with the Earthrealmers. Her betrayal was mainly the result of growing doubts as to the morality of her actions and resulting feelings of guilt, as well as anger at the discovery of the truth about her past and her true father, the late King Jerrod.
This led to her murder by her now-corrupted mother, Sindel, becoming one of Quan Chi’s revenants. After Quan Chi’s death, Kitana and Liu Kang became emperor and empress of the Netherrealm.
In Mortal Kombat 11, Kitana and Liu Kang are recruited by Kronika in her quest to restart the timeline, joining her due to her plans to erase Raiden from history. A younger Kitana is summoned along with various other Kombatants in the present era due to Kronika‘s plans. With Raiden and the others fighting alongside him, this younger Kitana aimed to stop Kronika‘s meddling so she could kill her father Shao Kahn. After rallying the sides of the Tarkatans under Baraka and the Shokans under Sheeva, she was able to defeat her stepfather and free Kotal Kahn from his near execution. As thanks, he revoked his ruler ship and crowned her the new empress of Outworld, Kitana Kahn.
After Fire God Liu Kang defeated Kronika and gained control of her Hourglass, he and Kitana acted as the moulders of the future after Raiden relinquished his title of Earthrealm‘s protector to the Shaolin.
