Jubilation "Jubilee" Lee is a fictional character, a Marvel Comics superheroine associated with the X-Men.
A mutant, Jubilee had the superhuman power to generate pyrotechnic energy plasmoids out of her hands. She is often illustrated wearing a yellow trench coat. A teenage "mall rat," she was the X-Men's youngest member in the early 1990s, often playing sidekick to Wolverine. She eventually joined the junior team Generation X. She was a prominent character in the 1990s-era X-Men animated series. In late 2004, Marvel launched a self-titled series for Jubilee set in Los Angeles, written by Robert Kirkman and covers by Casey Jones; it was canceled after six issues. She also has cameo appearances in all three X-Men films; she is portrayed by Katrina Florence in X-Men and by Kea Wong in X2: X-Men United and X-Men: The Last Stand.
Jubilee is one of the depowered mutant characters who later reappeared using technology-based powers in the New Warriors comic series. She has since been turned into a vampire where she gained vampire-like powers.
