After her debut episode, Viper appears regularly to assist the Chans, most notably as a member of the J-Team. She's also presented as a possible love interest to Jackie, though he greatly mistrusts her initially and their relationship is never much given attention to.
Viper is a lithe, attractive and very beautiful woman with long black hair worn in a side cortex, dark complexion and brown eyes. Her habitual in-field outfit consists of a tight, blue-black bodysuit and utility belt. When she's not in spy gear, her casual outfit is either a pink shirt and black tight shorts with pink sneakers or a sleeveless pink dress and sandals. When working as a security consultant, she wears either a gray business suit, consisting of a jacket and skirt with a pink blouse and black high heels or a red business suit, consisting of a jacket and skirt with a purple blouse and purple high heels.
It is hinted that Viper is Jewish (in Season 3, "A Jolly J-Team Xmas", she hosts a Hanukkah party). Though there are many times when Jackie doubts her trustworthiness due to her old thieving days, she is usually valued in times of need. She is often shown flirting with Jackie. This is encouraged by Jade, as she stated that she'd make a great aunt if she got together with him, with whom Viper shares a close big-sister relationship.
Originally, Viper first appeared as a master thief whom Jackie met in the New York Metropolian Museum, where the Snake Talisman was exhibited. Her original target, however, was the Pink Puma, a large pink diamond also on exhibition in the museum. At the very same night, Jackie (with Jade in tow) and Viper attempted to steal their respective targets, but caught each other in the act, and a fight ensued. During their scuffle, they lost the bags which contained their objectives, and accidentally picked up the wrong ones when the police arrived, so that Viper got the Snake Talisman while Jackie ended up with the Pink Puma and - subsequently - a stay in prison. Upon discovering the talisman's power, Viper used it to break Jackie out and agreed to a meeting with Jade to switch the talisman for the Pink Puma. However, the talisman she gave to the Chans was a fake, but as she returned to her apartment, she found Valmont and the Shadowkhan waiting for her. Viper fled from the Shadowkhan to the nearby Thanksgiving parade, where Jackie and Jade located and aided her against her pursuers. In the end Viper managed to slip off, though without any booty, and after her run-in with the Dark Hand she gave up her life of crime to work as a security consultant.
Later on Viper was recruited by Jade to become a member of the J-Team. She also aided Jackie and Jade in independent missions, such as apprehending the magical thief Origami.
