Jubilation Lee is one of the many X-Men characters often mocked for her powers. Introduced in Uncanny X-Men #244 in 1989, she started out as a homeless mall rat but eventually became a part of the Emma Frost and Banshee-led team of mutants in Generation X. Fans often misconstrue her powers as the simple ability to create firework-like blasts from her hands, but her former teacher Emma Frost has diagnosed her powers as the ability to destroy matter at the subatomic level, which is what creates her so-called fireworks.
Still, because Jubilee prefers not to harm anyone, she rarely ever utilizes her abilities to the fullest, and thus she generally comes off as a Dazzler clone without the awesome sense of fashion and music talents.
