Cheshire is a DC Comics villain. She first appeared in New Teen Titans Annual #2 (1983).
Born (allegedly, see below) to a French father and a Vietnamese mother, Jade Nguyen had an unhappy childhood and was sold into slavery. As a young adult, after killing her master, Jade was informally adopted by Chinese freedom fighter Weng Chan, who taught her all he knew about guerrilla fighting. She acquired knowledge of poison from Kruen Musenda, a famed African assassin known as the "Spitting Cobra" and to whom she was married for the two years prior to his death.
She is a long-standing rival of the superhero team the Teen Titans. However, when Roy Harper, a.k.a. the archer Speedy, went undercover for the government in a mission to get her confidence and turn her over, the two fell passionately in love. Knowing he would not be able to turn her in, he walked out; Cheshire would not learn his true identity until later. The result of their romance was a daughter, Lian, whom Roy raised.
Returning to her mercenary ways after leaving Lian behind for Roy, Jade saved Deathstroke's life so he could help her in stealing nuclear weapons from Russia in an attempt to blackmail the world. To prove she is not bluffing, she obliterates the fictional Middle East nation of Qurac, reasoning that since Qurac is a stronghold of Muslim terrorist, that Western countries would be secretly grateful. Cheshire's plans were foiled when her base came under attack and she was forced to flee. She later created her own team, The Ravens.
