Jade is a childhood friend of Princess Kitana. While her motives were unclear at first, she served under Shao Khan with Kitana and Milenna as one of Shao Khan's assasins for most of her life. When Kitana ultimately turned on Shao Khan, it was Jade who was ordered to capture her. Jade however, chose to side with her best friend and turned against the emperor herself. Since then, Jade has assisted Kitana in regaining Edenia's independance and insuring it's freedom. As well as protecting the majestic realm from the being taken over.Jade is an Edenian General as well as the founder of the Edenian Freedom Fighters.
Jade is a strong willed and self assured young woman. She is highly loyal to her realm as well as her best friend. While she was portrayed as a mysterious woman in her early appearances her personality has been expanded upon in recent games. Her comfort in herself and her body was revealed in her Girs Gone Wired video. In which she won Video Vixen of The Year. Jade is well known for her hatred of anyone who puts Edenia in danger.
Jade is well known for her rivalry with the traitor Tanya. This rivalry dates all the way back to Mortal Kombat 4, in which Tanya betrayed not only Liu Kang but her entire realm. This did not sit well with Jade and ever since the two are at constant odds with eachother.
You could say that as best friends, practically sisters, Kitana and Jade have somewhat of a friendly rivalry and they challenge each other to do better and suceed in their goals. In Mortal Kombat Deception, Jade had to fight against her longtime friend when Kitana was enslaved by The Dragon King. She locked Kitana in a cage in order to keep her from hurting anyone or worse, herself.
