The Birth:Jubilation "Jubilee" Lee was born and raised in Beverly Hills as the daughter of two prosperous Chinese immigrants, Dr. and Mrs. Lee. She attended an exclusive Beverly Hills school where she became an extremely talented gymnast. One weekend her parents lost their money in the stock market. That same weekend two hit men mistook Dr. and Mrs. Lee for their neighbors, also named the Lees, and killed them.
Orphaned and impoverished, with nowhere to live, Jubilee was sent to the Los Angeles County Juvenile Hall. There she learned how to defend herself and became rebellious towards authority. The Juvenile Hall authorities arranged to send her to another orphanage. Fearing that she might eventually be sent to live with her only living relatives, who were in Communist China, Jubilee ran away to the Hollywood Mall.
At first she survived as a petty thief, stealing whatever she needed. But one day, trapped by mall security police in a dead end, in her fear and panic she unwittingly activated her superhuman powers for the first time. Globules of energy, which she would later call "fireworks," shot from her hands, exploding in front of the police, enabling her to make her escape. From then on Jubilee led a lonely life, her outwardly cynical attitude hiding her deeper fear that she could not trust anyone. She earned a living by creating "fireworks" displays for the mall customers with her newly emerged abilities.
Jubilee made her debut in Uncanny X-Men #244.

The Alter Ego: There has been no need for Jubilee to adopt a secret identity since anyone who visited the mall while she was performing knew that she was a mutant. Jubilee, while a heroine, can be a bit hot-headed and stubborn at times. This could be mainly from the fact she was rebellious and anti-authority during her stay in the orphanage. Being the only person on the team under 18 didn't help her either. However, she did find friends in Beast and Iceman, the teams only real fun-lovers. However, she would eventualy realize that life was not a game.

The Legend: One day, mall security, having failed to capture her yet again, contacted the novice mutant hunters known as the M Squad. Luckily, several female members of the X-Men--Dazzler, Psylocke, Rogue, and Storm--happened to be shopping at the Hollywood Mall that day. They foiled the M Squad's attempt to capture Jubilee. Fascinated by these women, Jubilee followed them until they exited via a teleportation portal provided by the mutant aborigine Gateway back to the small town in the Australian outback, where the X-Men were then based. Before the portal closed, however, Jubilee jumped in.
She emerged in front of Gateway moments after the female X-Men had left the scene. Gateway verbally welcomed Jubilee, although he had never spoken to any of the X-Men, led her to a tunnel, and pushed her down into it. She landed in the vast underground cavern that stored the bounty of the Reavers, the criminal cyborgs who had previously been the town's sole residents.
Jubilee created a living space for herself within the cavern. Although part of her wanted to connect with the X-Men, she did not trust anyone yet, mutant or otherwise. So she kept her presence a secret, watching the X-Men from her hiding place. She became a scrounger, taking food and clothing from the X-Men while they were busy elsewhere.
She finally emerged from hiding after most of the X-Men had abandoned their Australian base and the returning Reavers had captured and crucified the X-Man Wolverine. After Wolverine succeeded in freeing himself, she helped him escape to safety. Wolverine, in gratitude, made her an honorary X-man.
Over the following months Jubilee accompanied Wolverine in his travels through Asia. He became like a second father to her.
Jubilee finally met Professor Charles Xavier, the founder of the X-Men, when they were both captured by the alien Warskrulls. Subsequently, when the X-Men reunited under Xavier's leadership, she became a full member of the team. She continued to accompany Wolverine frequently on his solo missions.
After the X-Men defeated the techno-organic Phalanx race, Xavier decided to found a new school where the various teenage mutants whom the Phalanx had captured would be trained in the uses of their superhuman powers. Hence, Husk, M, Skin, and Synch became members of a new mutant team, Generation X. Xavier assigned Jubilee to join this new team as well, since she was in their age group. She was not happy, seeing her reassignment as a demotion.
However, Jubilee quickly became the team player in Generation X that she had been with the X-Men. Despite her characteristically cynical remarks, Jubilee came to love and trust the members of her new team as if they were her new family.
In one of her major skirmishes, just before Operation: Zero Tolerance, Jubilee was kidnapped and subjected to a series of mental tortures by Bastion. The information he erected from her mind allowed him to breach the X-Mansions security and several potential weaknesses of various members. While captive, Jubilee was also able to sabotoge bastions efforts by helping to free the other X-Men that had been captured. She eventualy escaped as well, and meet up with the X-Men else-where in the desert, who returned her home.
After hearing that Wolverine had been killed, Jubilee, alongside Banshee, rushed to Westchester. She was relieved to discover that it was not Wolverine but in fact a Skrull impersonator, and after Wolverine was revealed to be Apocalypse's Horseman Death, Jubilee set out with Angel, Nightcrawler, and Shadowcat to free him of Apocalypse's control. After succeeding in their mission, they four, joined by Wolverine, headed for Egypt, but made a detour in Egypt where they faced Exodus. After having dealt with Exodus in Genosha, Jubilee is supposedly headed to Egypt to help stop Apocalypse.
Jubilee is a mutant with the superhuman ability to generate what she calls her "fireworks:" energy globules that vary in degrees of power and intensity. The globules obey her mental control, traveling where she directs them, arranging themselves in balls, streamers, and other shapes, and exploding when she wishes. These combinations may result in anything from a multitude of colorful sparkles capable of temporarily blinding a person to a fairly powerful detonation, capable of smashing tree trunks or metal objects. She can absorb these "fireworks" back into her own body without harm to herself. But with all her powers, she still has the strength of a normal girl her age.
