Jade is a childhood friend of Princess Kitana. While her motives were unclear, she served Shao Kahn alongside Kitana and Mileena as his personal assassin for most of her life. When Kitana finally turned against Shao Kahn, Jade was ordered to capture her for the Emperor. She ultimately chose to join her friend, and has since loyally assisted Kitana in her quest to free their native realm and restore its original beauty. Now residing in the freed Edenia, Jade is a General of the Edenian Army and continues to dutifully serve Kitana and her mother Sindel.
Jade's confident and sassy personality was first portrayed in her Girls Gone Wired campaign video, but later expanded upon throughout her story in Mortal Kombat (2011). Always known for her loyalty towards Kitana, she has proven herself to be a dependable, sincere and devoted friend to the princess. She is sarcastic, patronizing and cocky towards her opponents, and incredibly ruthless towards those she considers a personal enemy (at one point splashing Tarkatan essence on the Edenian traitor, Tanya, and allowing her to be torn to pieces by Baraka's militia).
As a female assassin adorned in a green skin-tight outfit, Jade was initially very similar in appearance to Kitana and Mileena, the only noticeable difference being her darker skin (although in the Sega Genesis and Saturn ports of MKII, she has the same skin as Kitana). She appeared first as a hidden, unplayable character in Mortal Kombat II whose moveset were mostly like Kitana's including the use of the fan blade weapon. To reach Jade, the player would fight a one-player game on the match just before the "?" on the map of the mountain. If the player won at least one round of the match using only the Low Kick button (no punches, High Kick, or Block button presses), they would immediately be warped to Goro's Lair to fight Jade. The player did not have to win the match -- only one round -- to fight Jade.
Jade would later become a regular character in Ultimate Mortal Kombat 3. Her main weapon of choice is a metal staff, but she also uses razor-edged boomerangs (dubbed "razorangs") as well.
Jade's introduction to the Mortal Kombat series is quite similar to that of Reptile's. (In the first Mortal Kombat, Reptile made his appearance as a green-colored version of Scorpion with both Scorpion and Sub-Zero's abilities.) Making her first appearance in Mortal Kombat II, she was a hidden, unplayable character that was simply a palette-swap of Kitana but which was extremely fast and who could not be harmed by projectiles. In most ports of MKII, she had brown skin (except for Sega Genesis/Megadrive, and Sega Saturn where she had Kitana's skin color). Jade's name was not superimposed over her MKII energy meter; its inclusion was likely forgotten by the programmers during production. Jade could be seen peeking out from a tree in The Living Forest Arena in MKII, as could another secret opponent: Smoke. It was then further suggested in the comic book series that Jade and Smoke were in fact assassins working for Shao Kahn. However, the comic books were non-canon.
When Jade made her first non-secret appearance in Ultimate Mortal Kombat 3, she was given her own attributes and storyline. The same happened for Reptile when he made his first non-secret appearance in Mortal Kombat II.
Jade also made an appearance in the game Mortal Kombat: Shaolin Monks as an assassin that fought alongside Mileena and Kitana. Her appearance sparked some controversy about the validity of the game's story, compared to established Mortal Kombat canon. After battling her, she is stabbed in the eyes with Mileena's sai by the player and dies.
Powers and abilities
When she was first introduced in MKII, Jade was the only secret character to possess an outright special ability: an absolute immunity to projectile attacks. Any projectiles thrown at her would fly harmlessly pass her. Aside from that, her style of combat was identical to Kitana's, wielding a pair of copper fans during gameplay.
When she was made playable, she displayed slightly more aptitude than her other counterparts. Unlike Kitana and Mileena, Jade wielded two weapons: a steel, sharp-pointed staff which transforms itself into a supply of 'razorangs' (a portmanteau of 'razor' and 'boomerangs'). She displayed the most effectiveness with the staff, preferring weapon combat over hand-to-hand combat. During one of her Fatalities and her win pose, the staff left behind purple energy trails, hinting at magical properties. The staff has also been redesigned twice, first displayed as mentioned above, but in Deception, given a larger spearhead at one end, whilst in Shaolin Monks, it is a simple iron staff with no sharp ends. In MK 2011, the staff reverts back to its original steel design, but heavily features the purple aura during gameplay as well, and has the ability to change length. She also displayed skill with the razorangs, able to retrieve her weapons as they returned to her without cutting herself and can alter their trajectory at will. Jade is able to emit a 'force rejection field' around her, which seems to cause projectiles in particular to fly right through her like air.
- Razor-Rang: Jade throws a razorang at her opponent. In the 2D games, there were three variations of this move: one that curved up, one that curved down, and one that returned if it missed the opponent. In MK 2011, this is renamed Boomerang, and has a straight throw, an upward throw called Boomerang Up, and a throw at the shin called Boomerang Down. (UMK3, MKT, MK:D, MK:U, MK:SM, MK:A, MK 2011)
- The enhanced version is called Reboomerang in which the razor-rang returns to strike the opponent a second time. The enhanced upward throw is called Reboomerang Up, and the enhanced lower level throw is called Reboomerang Down.
- Blazing Nitro Kick: Jade illuminates herself with a green force and kicks her opponent. In MK 2011, this is called Shadow Kick. (UMK3, MKT, MK:D, MK:U, MK:A, MK 2011)
- The enhanced version is called Eclipse Kick. This makes the kick go full screen and increases damage.
- Dodging Shadows: Jade puts a forcefield around herself which causes projectiles to go through her. This move is taken in reference to her automatic immunity to projectiles in MKII. In MK 2011, this is called Shadow Flash. (UMK3, MKT, MK:D, MK:U, MK:A, MK 2011)
- The enhanced version is called Shadow Glow and illuminates Jade in a purple glow instead of a green glow. This will give her immunity to the knockback effects of any attack, but she still takes the damage like normal.
- Vanishing Winds: Jade spins with a cloud of green smoke surrounding her and appears behind her opponent. (MK:D, MK:U, MK:A)
- Staff Overhead: Jade jumps up and smashes the opponent with her staff. (MK 2011)
- The enhanced version is called Staff Smash. Jade jumps and smashes the opponent quicker than Staff Overhead.
- Staff Grab: Jade grabs the opponent by the chest with her staff and slams them behind her. This move was once her grab move in UMK3. (MK 2011)
- The enhanced version is called Staff Slam in which Jade slams the opponent an additional two times.
- Vanishing Winds: Jade dodges any incoming special attack or combo ender used by her opponent, which she retaliates with a powerful, unblockable kick attack which will also disable the opponents ability to use special attacks. She can not dodge X-Ray attacks. (MKX mobile)
- Spinning Staff: Jade strikes her opponent multiple times with her staff, spinning it in a helicopter-like fashion and ending with an overhead strike. (MKX mobile)
- Tag Attack: When Jade enters the match from being tagged out, she charges the active opponent with a powerful kick, knocking them down. (MKX mobile)
- Tag-Out Attack: When a teammate tags in for Jade, she retreats, but bounces off her staff, dealing damage to the active opponent before she exits. (MKX mobile)
- X-Ray Move - Staff Buster: Jade rushes behind her opponent, grabs her staff and slams it in the groin. She then pulls it out and smashes them in the back with it, damaging their spine and nearby bones. (MK 2011)
- X-Ray Move - Staff Buster: Jade strikes her opponent with her staff, in a manner that causes both fighters to spin around. She then slams her opponent into their groin, which if done on a male fighter will cause their testicles to explode. She then rams her staff into the opponent's back, stabbing through their spine and shattering their ribs in the process. (MKX mobile)
- Staff Shake: Jade stabs the foe in the stomach with her staff, and shakes it to the point where the body blows up. (UMK3, MKT)
- Staff Impale: Jade uppercuts the opponent into the air, and promptly holds out her staff, as the opponent is pierced by it upon falling down. (UMK3, MKT)
- Jade Cutter: Jade runs past her foe after cutting him/her, and when she looks at the foe, the foe's upper torso and the lower body split apart and fall to the ground. (MK:D, MK:U)
- Head Kabob: Jade thrusts her staff into the opponent's head, then flips over and smashes the opponent to the ground, which separates the body and the head, the latter of which is still attached to the weapon, spilling blood. (MK:D, MK:U)
- Boss Fatality: She assists Mileena in this Fatality. Jade sweeps the enemy to the ground with her Bojutsu, Mileena then throws her Sai into the opponent's palm. Jade then slams her Bojutsu in his face, eventually crushing it. (MK:SM)
- Half Mast: Jade kicks the opponent into the air and plants her staff into the ground. After the opponent is impaled by the staff, she rips off his/her head and sticks it at the top of the staff. (MK 2011)
- Head-A-Rang: Jade throws a Razorang at the opponent, cutting off their head. The head stays on the opponent's body as if it wasn't cut. Jade then kicks the body away, letting the head fall off. As she kneels down to catch the opponent's head with one hand, she catches the returning Razorang with the other. (MK 2011)
- Animality: Jade turns into a cat and mauls the opponent to death. (UMK3, MKT)
- Friendship: Jade hops on her staff like a pogo stick. (UMK3, MKT)
- Hara-Kiri: Razorang Harvest: Jade throws her razor boomerang in the direction in front of her. Then it comes back and cuts off her head. (MK:D, MK:U)
- Babality: Giggling, Jade throws a razorang, but it comes back and hits her on the head, making her cry. (MK 2011)
Appearances in other media
Despite her portrayal as a "good" character in the games, Jade appears in Mortal Kombat: Annihilation (portrayed by Siberian supermodel Irina Pantaeva) as a character who remains loyal to Shao Kahn until her death. After failing to seduce Liu Kang and leading the other warriors to an ambush (not before testing Liu Kang and leading him to the Temple of the Elder Gods), Kahn himself has her eaten and swallowed by a living gargoyle in his palace due to her alleged failure at keeping the Earth Warriors from escaping. There is also little to no indication in the movie that Jade and Kitana know each other from the past. Instead, Kitana glares at Jade when she betrays the group during a later part of the film.
Jade appears in the novelization of both feature films. Her role in the first novel is very small, appearing only on one page before being tricked by Sonya and defeated with a single blow. It is interesting to note that instead of fighting with any of the three weapons she uses in the games (fans, staff or razorangs), Jade displays great proficiency with a pair of half-moon daggers, capable of moving them so fast around herself that she can shield herself from attack.
Jade's role in the novelization of Mortal Kombat: Annihilation is expanded, and a history between her and Kitana is hinted at, but Kitana is disgusted by her arrival rather than friendly with her (which would explain Kitana glaring at Jade in the movie). She fakes subduing Sindel and lures the Earth Warriors into a trap, distracting them long enough for the Extermination Squads to get close, before escaping. Like in the film, despite Sindel's testimony to Jade's loyalty, Shao Kahn has her devoured by a living stain-glass window for allowing the Earth Warriors to survive.
Jade doesn't appear in Jeff Rovin's non-canon Mortal Kombat novel.
Jade has a minor role in Malibu Comics second series Battlewave. Since her participation in Mortal Kombat II wasn't revealed during production of the comic, Jade's portrayal and personality is highly different from her in-game canon story and traits. In the comics, Jade is an evil assassin under Shao Kahn's command, and shows no relation or ties with Kitana besides their shared looks. She is always paired with Smoke, possibly due to both of them appearing on the background of the Living Forest stage in Mortal Kombat II.
Jade and Smoke attempt twice to kill Jax (and later Johnny Cage) before they arrive in Outworld, but both times, they fail to do so. Later, they try to redeem themselves by killing Raiden during his fight with Kano (the third issue of the mini-series Rayden and Kano), only to be stopped by Kano himself. She is also present as one of the wedding guests for Shao Kahn and Sonya's wedding in issue #6 of the Battlewave series.

- In MK:D's Konquest Mode, Jade asks Shujinko to bring Rain to the Edenian Freedom Fighters, and in completing this, she defeats him.
- In Mortal Kombat II, Jade occasionally drops down during a match and gives clues on how to reach her just as Reptile did in Mortal Kombat. One of her clues is a reference to the Ermac rumors from Mortal Kombat.
- One of the clues Jade leaves is her saying "Chun who?" which is a reference to Street Fighter's Chun Li, a fighter known for her incredible strength in her kicks. This was a clever hint at how to fight Jade in which the player would have to defeat the opponent using only low kicks.
- In the Sega Genesis version of UMK3, Jade's fighting stance is a version of Mileena.
- In the SNES version of UMK3, Jade's fighting stance is a version of Kitana.
- Jade is the first hidden female character in the series, the first male being Reptile.

- This is also the only Fatality in which Jade does not use her staff to kill her opponent.
- In MK 2011, Jade, along with Mileena, Sub-Zero, and Kitana, has the most costumes with a total of 4 while everyone else has either 2 or 3.
- In Mortal Kombat (2011), Jade's primary costume is similar to her alternate costume in Mortal Kombat: Armageddon, while her alternate costume is similar to her Mortal Kombat: Armageddon primary costume, both only switching the hairstyle.
- In Mortal Kombat: Deception and Mortal Kombat: Armaggedon, Jade's staff doesn't emit a purple glow like in the other games she appeared in.
- In the Story Mode of MK 2011, when Sindel enters the Cathedral, Jade is seen in her alternate costume, holding her MK:D staff. However, when her alternate costume is chosen, the staff is not seen in.
