Kiteena

Kiteena is the family ship between Kitana and Mileena from the Mortal Kombat fandom.

Fanon
While Mileena is an evil clone of Kitana, there have been fans who treat Kitana as a femslash ship. Some feature them as selfcest, as clonecest, as non-sisters (such as in Conquest), or ship them as incest.

Depending on the Writer, Mileena may hate Kitana out of jealousy, or want to truly be accepted, be it as family or as a lover. Mileena has all of Kitana's technical skill and fighting prowess, as shown in a "Mortal Kombat: Onslaught" cutscene, where they fought to a standstill. She is therefore Kitana's equal in physical ability which fanfiction writers often write as desirable. While Kitana's outfits do show some skin, Mileena's have been more revealing since Deception. Occasionally written as Mileena displaying herself for Kitana's gaze, or because she is more confident with her body despite being a clone.

In MK3, Mileena has the ability to read the thoughts of her twin "sister" clone, which enable the Kahn to stay one step ahead. While not present since, this could still be true in other timelines, having Mileena know Kitana's inner most desires. In MK1 Mileena is confirmed to be protective of her other half when certain characters mock her about taking Kitana captive in their pre-battle banter, to which she is furious.

As Kitana notes in MK1's storymode, romantic entanglements with the Umgadi are forbidden, possibly written as steering Mileena away from Tanya, and further into her role as Empress alongside her.

Moments

 * In the reboot timeline of Mortal Kombat X, she flirts heavily with many of the kombatants in their intros... but she also does the same with her "sister" Kitana, and with Jacqui Briggs. (Mileena was kind of gushing over her "sister's" beauty when they first met in the last game)
 * In 2023, the Twitter account for the Mortal Kombat Mobile Spin-Off game posted a piece of official art featuring Mileena alongside the franchise’s other LGBT characters in celebration of Pride Month. This marks the first time Netherrealm has made any sort of official acknowledgement of her sexual orientation.
 * Before becoming playable in the Ultimate expansion, her only appearance in MK11 was part of Kitana's Friendship, happily playing patty-cake with her before sharing a loving hug.
 * Throws a tea party for herself in her MK11 Friendship, using plush teddy bears to represent herself, Kitana and Jade.
 * In Mileena's Armageddon ending, she temporarily merges with Kitana and when they separate, they discover they have switched features, with Mileena having Kitana's beautiful face while Kitana has Mileena's Tarkatan teeth. Mileena impersonates Kitana and has the real Kitana imprisoned, causing the latter to go insane.
 * Mileena proves to both Kabal and Liu Kang that she can imitate Kitana's voice perfectly.
 * Mileena was originally hurriedly raised by Shao Kahn and thus, never knew genuine love or affection, resulting in a deep-rooted desire for affection and praise but Kitana simply rejects her as a monster.
 * In direct contrast to Kitana's "Blue Is Heroic" attire, some of Mileena's attire is pink.
 * Inexplicably in the latest film of the franchise Mileena is played by black actress Sisi Stringer, despite being a clone of a supposedly Asian-looking woman i.e. Kitana. This may imply the two share no or little relation in the film's universe which will be revealed in the upcoming sequel.
 * Nearly all of Mileena's arcade endings before the reboot have her assuming Kitana's identity and seizing Edenia for herself. She is Kitana-obsessed.
 * In Mortal Kombat 1, Kitana and Mileena have always been at odds in previous timelines, with Mileena being a half Tarkatan clone who spitefully envied Kitana's beauty, love and acceptance to an often murderous degree, whereas Kitana for her part despised Mileena as an abomination made in her image. Here, the two are genuine twin sisters who love and care for one another, with Kitana being dedicated to aiding and defending her older sister.
 * In MK1, while Mileena's romance with Tanya confirms her interest in women, she complains to Kitana about being expected to produce an heir, to which Kitana agrees
 * Kitana's intros with Ashrah imply that while Kitana has no evil in her heart, Mileena might not be quite so pure.
 * Mileena's pre-fight intros have also her being a lot more temperamental and eager for violence than Kitana, who often tries to rein her in.
