Jade's History
Jade first appeared in the Mortal Kombat tournament held by Shao Kahn, where it is assumed she was spying on the events unfolding for her then Emperor.
Like Kitana, Jade's origins were not from Outworld. She originated from the realm of Edenia, a realm conquered many years ago by the emperor, Shao Kahn. A longtime ally of the Edenian crown, and a close friend to Princess Kitana, Shao Kahn had her trained to be a proficient and formidable assassin under his command.
Unlike most characters in the game, Jade has her own stage in the game series called Jade's desert which is located in outworld. The desert came from her ancient home world of Edenia and somehow became a part of outworld, Jade owns the desert and makes it her home.

Jade made her first appearance in this game as a secret character. She is a heroine under Shao Kahn's control and was sent to spy on the events happening in the tournament. She watches each fight without being seen the only time Jade is noticed spying on the fighters is in the living forest. Jade shows up in the middle of the background during some of the fights telling the kombat competitors what they have to do for them to face her later on. Jade gives some clues to help the kombatants so she can get her chance to fight.

During the Earthrealm invasion by Shao Kahn's army, Kitana was sentenced to death after pleading guilty to treason and murdering Mileena during the events of the second tournament. She escaped Outworld and fled to Earthrealm. Enraged, Shao Kahn appointed Jade and Reptile to venture into Earthrealm and capture the princess. Jade was assured that Kahn wanted Kitana back alive, but Reptile was secretly told to bring Kitana back by any means necessary including death.
The two ventured to Earth to find Kitana. However, Jade found herself torn between loyally carrying out Kahn's orders and betraying her friend. She ultimately decided to help Kitana and thwarted Reptile's assassination attempt. With his defeat, the path was cleared for the two women to join Raiden and his Earthrealm combatants in the battle against Shao Kahn and his forces. Of immediate importance, however, was Kitana's mission to reach and warn the resurrected Queen Sindel about their true past together. Jade's assistance made that possible, with Sindel's memories recovered, she turned against the emperor. Shortly afterward, Shao Kahn was defeated by Liu Kang and Kitana went on to free Edenia from Outworld.

Heartbroken, Jade knelt beside her fallen friend's side and noticed a large creature approaching. She then hid in the nearby shadows and watched as Onaga, the Dragon King, resurrected the bodies of Kitana and her fallen friends. The spell allowed Onaga to control the warriors, and he ordered his recruits to regroup in the Living Forest.

Before they went through the portal, Jade caught a glimpse of the traitor, Tanya, standing next to Onaga.
In Outworld with Sindel, Jade made it her personal mission to assist her Queen in rescuing Kitana from the Dragon King's spell and to seek justice against Tanya, who had betrayed Edenia once again.
Mortal Kombat: Armageddon
After Ermac and the spirit of Liu Kang successfully managed to free Kitana, Jax, Johnny Cage, Kung Lao, and Sonya Blade from Onaga's influence, Onaga was soon incapacitated by Nightwolf's Sin Eater ritual, temporarily quelling any imminent danger to the realms. But unbeknownst to the heroes, was that a new, more fatal threat, was soon approaching. The fabrics of the realms were beginning to tear apart as the warrior's all grew stronger, which would result in Armageddon. To prevent this, an Edenian half-god known as Taven needed to defeat the fire spawn, Blaze, and claim Blaze's power to nullify the strength of the warriors. But word had spread of Blaze's power, and the Forces of Darkness sought to acquire it.
Jade joined the Forces of Light in an attempt to stop the Forces of Darkness' efforts in defeating Blaze the fire spawn.

Mortal Kombat 11
While Revenant Jade is a supporting antagonist, a younger Jade from before her death is brought into the present time by the manipulations of the Kronika Titan.
While infiltrating Camp Tarkata, Jade discovers Kotal Kahn's new stone heart when he wants to execute all the Tarkatans without exception, forcing Jade to confront her love from another time. After knocking out Kotal, she is captured by Shao Kahn and tortured by Skarlet before being rescued by Kitana, Liu Kang, and Kung Lao.
She is then part of Kitana's forces invading the Outworld arena to prevent Kotal from being executed. Although Shao Kahn is defeated, the evil emperor had time to smash Kotal's spinal column but Jade assures him that he is not helpless while he is with her.
She later participates in the takeover of Fort Kronika but the Titan reverses time at the height of the battle, wiping out Jade.
Jade reappears in the follow-up DLC Aftermath where she crosses paths with Sheeva, Shang Tsung, Fujin, and Nightwolf as they travel to the Chamber of Souls to resurrect Sindel. Having no faith in the evil wizard and with Kotal being cured of her fight against Shao Kahn, Jade refuses to let the quartet pass and ends up fighting Sheeva but Queen Shokan is able to defeat her.
Jade's last appearance is during the crossing for Kronika's Fortress but due to Shang Tsung's machinations, the normal flow of events is completely altered. The ship on which Jade is standing, Kotal (who in this timeline is healed enough to participate in the battle), Kung Lao, Liu Kang, and Kitana is stormed by Shao Kahn and Sindel as well as their Shokan minions. Jade confronts the Shokans as best as she can before being confronted by Sindel and then helplessly witnessing Kotal's death at the hands of Shao Kahn before Sindel slams her through the hull.
