Sindel's History
Sindel's storyline begins tragically 10,000 years ago, when her kingdom was invaded by Shao Kahn, and she was forced to watch as her husband King Jerrod was killed, her people enslaved, herself becoming Kahn's wife through a forced wedding, and her daughter with Jerrod, Kitana, was adopted by Kahn as his own daughter shortly thereafter. This proved too much for her as a mother, wife, and queen, and soon after the invasion, she committed suicide to escape what she believed was eternal subservience to her new husband, but Kahn wouldn't let his new Queen go so easily and held her soul in Outworld by an unknown means, stopping her transition to the afterlife.
However, this would not be the end of her. Gaining aid from the wicked Elder God Shinnok, Shao Kahn would conspire to bring his beloved back to life, but not in Outworld. Instead, her resurrection would take place on Earth, which would allow Shao Kahn to step through the borders separating the realms and claim her for himself, thus forcing a merger between Earth and Outworld. She would also be revived in a brainwashed state, with no knowledge of her past and having complete loyalty to her "husband" Kahn. After the sorcerer Shang Tsung failed to secure Earth via the Mortal Kombat tournament, Kahn implemented this plan, and was partially successful: Sindel was reborn just as was planned, and Kahn was able to garner a partial merger of the realms by her revival before Earth's warriors defeated him. However, Kahn didn't just lose Earth in his defeat; Kitana - realizing that her mother was alive - succeeded in procuring an audience with her and convincing her of her true past, thus turning Sindel against the emperor. As Kahn's defeat also succeeded in separating it from their homerealm of Edenia, Sindel took up her rightful place on its throne, and vowed not only to rebuild their home, but to also bring down Shao Kahn for his many crimes.
However, those plans had to wait, as one of Sindel's people, the daughter of an Edenian ambassador to the realms named Tanya, betrayed her homeland and allowed the Netherrealm forces of the fallen Elder God Shinnok to invade the palace and the entire realm of Edenia. Though Kitana got away, Sindel herself was captured and held in her own dungeon until Shinnok's forces were defeated. Enraged at this latest invasion on her kingdom, Sindel sent Kitana to form an alliance with the Shokan armies and lead them into battle against a weakened Shao Kahn while she continued to help restore Edenia to its former beauty.
Unfortunately, Sindel's plans on restoring Edenia would once again have to wait. With the formation of the Deadly Alliance, it brought conflict between Kitana, her old friends, and her alliance and they were slain in battle only to be later resurrected by Onaga the Dragon King as mindless warriors under his control.
Edenia eventually fell to Onaga and Sindel was kidnapped, locked away in one of her own palace dungeons with the brainwashed Kitana serving as her guard. Sindel did not try to free herself, knowing that it would require her to harm her own daughter. With the aid of the traitor, Tanya, he would begin to scour the kingdom for the missing Kamidogu, the sources of his new and true power. Luckily, Jade managed to defeat Kitana, free Sindel and escape with her to Outworld.
Sindel joined the Forces of Light for the Battle of Armageddon. She is killed by an unknown kombatant who stabs her with a sword.
In the alternate timeline, Sindel was declared dead. But after Shao Kahn lost in Mortal Kombat, Quan Chi suggested invasion but in order to do that Quan Chi has to resurrect Sindel, the woman who cast a spell through her own death, so Shao Kahn can't leave Outworld and enter Earthrealm, thus Earthrealm itself wouldn't suffer as have Sindel's forgotten kingdom of Edenia. When Quan Chi resurrected her, Quan Chi told her that her daughter sided with the warriors of Earthrealm. She then stated that Kitana is no longer her daughter, and sided with her husband, Shao Kahn.
After the death of Motaro, Sindel went to Earthrealm and finish what Motaro started. But before she did, Shao Kahn suck the soul out of Shang Tsung and gave his power to Sindel giving her more strength and abilities during the fight the heroes tried to fight her but Sindel was to strong capable of defeating them easily without getting hit. She was then faced against her daughter who was overpowered by Sindel by brutally beating her without hesitation. Sindel killed; Jax, Kabal, Jade, Smoke, Stryker, Cyber Sub-Zero and her daughter, Kitana with little effort. She was then killed by Nightwolf by sacrificing his life to end her life. However Quan Chi resurrected all the heroes who lost their lives as well as Sindel and he forced them to serve him for all time.
For the next 25 years, Sindel continued to serve Quan Chi. Sindel became one of the main enforcers of Shinnok. In the early part of the game during a flash back Sindel, Stryker and Kabal show up at Raiden's temple With Quan Chi and a demon army. The Revenants attack Raiden and Fujin who are defending the temple both of the gods defeat the demons and then battle the three Revenants. Raiden defeats Kabal first Fujin defeats Stryker second and Raiden defeats Sindel third Quan Chi then summons Shinnok. After Sonya, Johnny and Kenshi show up to help the two gods they defeat Shinnok but Quan Chi, Sindel and the other two revenants escape.
Sindel appears in chapter six of MKX along with the revenants of Liu Kang, Kitana, Kung Lao, Smoke, Kabal, Nightwolf and Stryker. They were escorting Quan Chi and got attacked by Jax, Kenshi, Sareena and Special Forces who were trying to stop them from getting Shinnok's amulet.
Unlike Stryker, Nightwolf and Kabal who returned to Shinnok's palace and have been MIA Sindel showed up in Earthrealm with Liu Kang, Kitana, Smoke and Kung Lao to help Shinnok take control of Raiden's temple to use his portal. She and the other Revenants fought and attacked Bo' Rai Cho and Raiden but she and the other Revenants lost after Cassie Cage and her team showed up.
With their defeat the revenants returned to the Netherrealm. After Raiden purifying the Jinsei the thunder god had become a darker version of himself and traveled to the Netherrealm now ruled by Liu Kang and Kitana. Raiden who is now more intimidating and more menacing spoke with the new rulers alone without Sindel, Kung Lao, Smoke and the other revenants being present. The dark thunder god gave a warning to the emperor and empress about what would happen to those who dare to attack Earthrealm this includes the revenants who now follow Liu Kang and Kitana.
Sindel is a DLC character in Mortal Kombat 11 as part of the Kombat Pack. Although she was leaked prior to this date, she was formally revealed on June 1st, 2019, alongside Nightwolf, Spawn and two other then-unknown guest characters (revealed to be the Joker and the Terminator).
In this game, her backstory was retconned revealing that she betrayed and killed King Jerrod when Shao Kahn threatened to take over her kingdom. It was also implied that Quan Chi murdered Sindel.
As a Revenant, Sindel is first seen confronting her enemies in the Bone Temple as they lay captured. Seeking revenge on the past version of Nightwolf for her demise, she plans to kill him as well, before her nemesis frees himself and knocks her out. With Sheeva being convinced to revive her, she tells Kitana that she never abandoned her family and was actually murdered by Quan Chi, as well as spinning a tall tale of being manipulated by Shao Kahn. She then joins the heroes.
Along with Nightwolf, they both decide to stay to look for the Crown of Kronika. However, Cetrion appears and planned to kill the two, but is defeated by Sindel. She later heads off to Outworld to aid her daughter.
Secretly shaming Kitana for her "foolishness" to Shang Tsung, she later freed Shao Kahn from being tortured, defeated Sheeva, convinced the other Shokan that Kitana was a traitor, and restored her husband in the Soul Chamber.
The Shokan then attack Sonya Blade and her forces, with the former being knocked out. She then defeats Johnny and Cassie Cage, capturing them and storming the hero's boats. Sindel and Shao Kahn defeat Kotal Kahn, and Jade, before revealing to Kitana that she killed Jerrod herself and married Shao Kahn on her own desires. Sindel then defeats her and Liu Kang, with the former imprisoned and the latter crippled by Shao Kahn. Kotal Kahn is also murdered by Shao Kahn.
After this huge blow to the heroes, Shao Kahn and Sindel rally Outworld's forces, with some attacking the other armies the some others going with Shang Tsung to get into Kronika's keep. Following the deaths of the revenants, Sindel and Shao Kahn plan to defeat Kronika as well, only to be betrayed by Shang Tsung and their souls absorbed into the malicious mage.
