Mileena/Current Timeline

""As the heir to my father Shao Kahn, I, Mileena, Kahnum of Outworld, order your execution!""

- Mileena to Kotal Kahn in Mortal Kombat X.

Biography

 * Mortal Kombat (2011): "Shang Tsung has created many abominable creatures in his Flesh Pits, but none so twisted as Mileena. A fusion of Edenian flesh and Tarkatan blood, Mileena is both beauty and beast. This dichotomy has made her mind unstable; she is prone to fits of madness and savagery. Though she has the appearance of a mature woman, she is more child than adult--a blank slate conformed to Shao Kahn's will. Devoid of conscience or remorse, Mileena will butcher anyone to appease her beloved father."
 * Mortal Kombat X: "Perceiving a lack of loyalty in his adopted daughter, Kitana, Shao Kahn ordered Shang Tsung to create a replacement, a daughter worthy of succeeding his rule. Shang Tsung fulfilled Shao Kahn's order by fusing Tarkatan DNA with genetic material stolen from Kitana to create a cloned hybrid: Mileena. Mileena is the best of both: bloodthirsty and vicious as a Tarkatan but possessing the Martial artistry and expertise of an Edenian. When Shao Kahn was killed by Raiden, Mileena took over as the ruler of Outworld. But when she refused to align Outworld with Earthrealm against Netherrealm's attack, she was deposed. She now leads a rebellion against the usurper Kotal Kahn's regime."

Mortal Kombat (2011)
Mileena is first discovered by Kitana in Shang Tsung's Flesh Pits, after the Princess witnesses a sleeping clone lying on a table. When she awakes, she refers to Kitana as "Sister", and mockingly asks the Princess to come to her and become a family. Kitana is horrified by Mileena's creation, calling her a monstrosity, and attacks and defeats her. After confronting Shao Kahn about her creation, the Emperor reveals he knew about this the whole time. He sentences Kitana to execution for consorting with Raiden and the Earthrealm warriors. He then orders Shang Tsung to fetch his "true daughter" from the Flesh Pits. This prompts Jade to rescue Kitana, but having alerted the guards to her presence, Kitana pleads with Jade to escape and find help. Mileena then appears later in the Wastelands after finding Jade, remarking that whilst others pursue, she finds. She asks Jade to return with her to the "going away celebration" for her sister, cruelly teasing Jade about Kitana's execution. After defeating Mileena, Jade remarks that she is more of a sister to Kitana than Mileena. When the Earth warriors appear, Smoke confuses Mileena for Kitana, unaware that Mileena is Kitana's clone. This prompts him to attack Jade before she has the time to explain that Mileena is not the Princess. Mileena uses this opportunity to escape. She is later seen at the coliseum, standing beside Shao Kahn.

After Shao Kahn's defeat at the hands of Liu Kang, Baraka points out that Mileena is the next successor to the throne. Shao Kahn, however, emerges, thus keeping his reign as emperor. Mileena is quick to bow before her father who explains that Quan Chi healed his wounds. During the Earthrealm invasion, Mileena is spotted by Kurtis Stryker and Kabal witnessing the carnage unfold on the streets of New York. Stryker notes that Mileena is definitely a foe, whilst Kabal isn't sure (due to the small amount of clothing she is wearing). Stryker approached Mileena, and they face off, with Stryker proving victorious.

After Kabal is burned by Kintaro, and later revived by Kano, he forces the Black Dragon thug to lead him to the Emperor's throne room. When he arrives, Mileena is seen entering the room with Lin Kuei Cyborgs and Tarkatans, bringing with them the corpse of Motaro. She informs her Emperor that Raiden has slain the Centaur General. While Shao Kahn is transferring Shang Tsung's essence into the bewitched Queen Sindel, Noob Saibot and Mileena both intercept Kabal as he attempts to attack the Emperor. Kabal defeats them both in a two-on-one match and then escapes back into Earthrealm. Mileena is not seen again after her defeat by Kabal.

Mortal Kombat X Comic
After Shao Kahn's death, Mileena became the new Empress of Outworld.

During the beginning of her her reign, she forced the Kytinn D'Vorah to kneel down and kiss her boot, and kicked D'Vorah's jaw when she attempted to do so, mockingly declaring D'Vorah her humble servant while being delighted she did not fight back.

Mileena's rule proves worse and more tyrannical than her father's and she was labeled the Mad Empress, driving Outworld to the brink of disaster. Kotal Kahn eventually usurped her rule, and with Reptile by his side as they confronted her in a coup d'etat, she was forced into exile. Mileena was joined by former general of Outworld's army, Reiko, and Edenian traitor, Rain, and the rebels are forced into hiding for ten years.

Mileena would take Reiko as her lover and closest adviser, but she was unknowingly being manipulated by the former general for his own purposes.

Mileena is seen in Raiden's visions along with Reiko.

Mileena learns from Reiko that the Red Dragon have agreed to aid their cause, which pleases her. She then convinced Goro to join her cause after the Shokan Prince found her hideout in the Golden Desert, playing on Goro's desires for revenge on Kotal Kahn for reducing his people's status.

While Goro rallies the Red Dragon as Kotal Kahn comes to avenge his father's death, Mileena discusses with Reiko how she will regain her throne, but Reiko tells her that Goro will seek to challenge her rule. Mileena is confused by Goro's treason, but after Reiko tells her that Goro's betrayal of Kotal will lead to him betraying her, an enraged Mileena bares her fangs and vows to devour the Shokan's face. Clinging to her lover, Mileena croons that Reiko is the only one she can trust.

After Kotal Kahn defeats and cripples Goro, the temple Mileena used as a hideout in the Golden Desert is burned to the ground, but Reptile reveals that both Mileena and Reiko escaped beforehand.

Mortal Kombat X
Five years before the main events of the storyline, Mileena confronts Kotal Kahn, D'Vorah and Reptile as they are conspiring to dethrone her. Reptile intervenes and claims that her succession is illegitimate since she is an artificial creation and not Shao Kahn's biological daughter, but she retorts this by saying she is his heir by decree. Kotal gives her one final plea to listen to his advice, but she refuses and orders a Tarkatan to kill him. Ermac then betrays her, saying he will serve whom who he chooses, and they engage in a fight. Mileena’s army is wiped out, including Baraka, and she is imprisoned by Kotal Kahn, who becomes the new emperor of Outworld. At some later point in time, she is freed by a group that includes Tanya and begins a rebellion to reclaim the throne.

In the present day, Mileena launches a sneak attack on Kotal Kahn in Z'Unkahrah with Rain, Tanya and Kano, whom she paid to assassinate Kotal. However, all four of them are defeated by the emperor. Before Kotal Kahn can execute her, Mileena uses Shinnok’s amulet to protect herself. But she collapses afterwards and Rain escapes with her. Wielding the power of the amulet "without precision", Mileena also destroys Li Mei's village and causes its citizens to be displaced in Earthrealm as refugees. It is later revealed by Rain that wielding the amulet kills her slowly, part of his plan to take Outworld's throne for his own after both Kotal and Mileena have been disposed of.

The Special Forces learn of Mileena's location from Kano after he is captured, and Cassie Cage's group is sent to the Kuatan Jungle with Kotal Kahn's army to retrieve the amulet. Mileena stumbles upon D’vorah and Cassie in her tent while they are trying to steal Shinnok’s amulet and fights the former, but is defeated and brought to Kotal Kahn. He considers her unworthy to be executed by his hand, and ushers D'Vorah to do so. She unleashes her flesh eating parasites on Mileena through a kiss while Cassie and her group look on, visibly disgusted.

Ending

 * Mortal_Kombat_Mileena_Ending_VideoMortal Kombat (2011) (Non-Canonical): "Mileena killed the emperor in a fit of deranged fury. But she was unaware that her victory resulted from Shang Tsung's designs. He had imbued Mileena with the ability to drain Shao Kahn's dark magic, rendering him vulnerable. Now Shang Tsung was ready to execute the next phase of his plan: murder Mileena and take Shao Kahn's power for himself. But Mileena instinctively wielded her new dark power against the sorcerer. Shang Tsung's end came quickly. Mileena absorbed his soul, multiplying her strength. She then set out to claim an even bigger prize: the soul of a thunder god."
 * Mortal Kombat X: "Overcome with exertion, Mileena collapsed and felt her soul gliding through the ether. She awoke in an incubation chamber. Nearby were countless others- each containing an exact copy of her. Mileena found she could read each being's mind, and they hers. They quickly realized the benefit of so many fierce warriors sharing one mind. As they plotted revenge on their enemies, the architect of the Mileenas laughed quietly."
