Jade is a video game character from the Mortal Kombat series. She debuted in Mortal Kombat II (1993), at first as an unplayable secret character and became a player character in Ultimate Mortal Kombat 3. Eventually, Jade became one of stalwart supporting characters, also featured in some of the related media and in merchandise in the Mortal Kombat franchise. She received positive critical attention due to her sex appeal and brutal fighting style.
In Mortal Kombat II, Jade was a mysterious hidden character with no part in the game's storyline whatsoever. In Mortal Kombat: Shaolin Monks, the 2005 beat'em-up retelling of MKII, she appears to fight against Liu Kang and Kung Lao alongside Mileena and Kitana; when defeated, she is stabbed in the eyes with Mileena's two sai by the player's character, killing her.
Jade returns in Ultimate Mortal Kombat 3 (1996) in which her backstory as a fellow Edenian and long-time friend of Kitana is revealed. She once served as Shao Kahn's elite assassin along with his adopted step-daughter Kitana (and later also Mileena). After Kitana was put on trial for Mileena's murder and escaped to the Earthrealm, Jade was ordered by Kahn to bring Kitana back to Outworld alive. However, he also sent his warrior Reptile with Jade, ordering him to kill Kitana if necessary. The two located Kitana and Jade narrowly prevented Reptile from killing her. Convinced by Reptile's actions and Kitana's words, Jade turns against Kahn and aids Kitana in freeing her resurrected mother, Queen Sindel, from Kahn's mental control. The three later join with Kitana's Earthrealm allies to help defeat Shao Kahn.
After they liberate Edenia from Outworld, Jade serves Sindel and Kitana for years. Sometime after Mortal Kombat: Deadly Alliance, she witnesses the death, resurrection, and capture of Kitana and her allies by Onaga under an enslaving spell. In Mortal Kombat: Deception (2004), Jade rescues Sindel from imprisonment in the Edenian palace dungeon. They escape to Outworld, attempting to free Kitana from Onaga's sorcery. Jade also attempts to seek revenge against the traitorous Edenian Tanya. In the game's Konquest story mode she orders Shujinko to bring the Edenian traitor Rain to her.
In Mortal Kombat, the 2011 reboot of the series, Jade is a member of Edenian noble family that served Shao Kahn once he conquered their realm, and she was given to him as tribute when she was a child. After years of rigorous training and service as an assassin, Jade has earned a reputation as an agile and stealthy warrior, and was awarded the position of a bodyguard to Princess Kitana. Over the centuries she and Kitana have become close friends (Jade replaces Mileena as Kitana's partner, in a retcon of the MKII storyline). Under the emperor's orders, the two of them initially fight the Earthrealm warriors. Later Jade suspects that Kitana is not following orders and unsuccessfully attempts to stop Kitana from learning the truth about her heritage. After learning the truth from Mileena, Jade switches her allegiance and helps the Earthrealm fighters to free Kitana from captivity. Later, Jade joined also the Earthrealm warriors during the invasion of Earthrealm. However, when Sindel arrived, Jade was killed by Sindel. She was last shown in the Netherrealm, as one of the warriors resurrected and enslaved by Quan Chi.
