Viper (Jackie Chan Adventures)

Viper is a cat burglar who reforms and becomes a recurring character in the animated Jackie Chan Adventures series. In her first appearance, she is stealing from New York Metropolian Museum a diamond called the Pink Puma at the same time as Jackie and Jade are retrieving the Snake Talisman from the same place. After they accidentally swap their targets and Viper comes to like the Talisman's invisibility power, she tricks Jade to exchange the Pink Puma with a forged Talisman. The Shadowkhan attack her and she's assisted by Jackie and Jade against them. She leaves without any booty, but somewhere along the line she reforms and becomes a security consultant.

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.
