Jubilation Lee

The daughter of two prosperous Chinese immigrants, Jubilation "Jubilee" Lee, was born and raised in Beverly Hills, California and lived a charmed life. Jubilee attended an exclusive Beverly Hills school and was believed to have the gymnastic potential to participate in the Olympic Games. However, all in one fateful weekend, her parents lost their money in the stock market and were then mistaken for their neighbors (also named the Lees) and killed by two hit-men, while Jubilee was out with a friend of the family.

Jubilee was then sent to an orphanage, but ran away and hid in a Hollywood shopping mall, stealing food to survive. Jubilee first discovered her mutant power, to generate blinding and explosive energy "fireworks", while running away from mall security. The stress of running away from the security guards caused Jubilee to emit a large light energy blast while in a back alley. This completely disoriented the men and allowed the frightened young girl to escape. Upon learning about her mutant ability to create fireworks, Jubilee realized she could earn money by using her powers to entertain customers and visitors in the mall.

Frustrated with the young girl's rebellious nature and powerful light-shows, the mall security hired mutant hunters, known as the M-Squad, to capture her. Jubilee held her own by blasting the M-Squad's energy tractor beams, but she was eventually caught. Lucky for her, Jubilee was rescued by the X-Men Dazzler, Psylocke, Rogue, and Storm, who happened to be shopping at the mall. Curious about these strange women, she followed them for a while and later jumped into a portal after them.

On the other side of the portal, Jubilee found herself at the X-Men's temporary base in the Australian outback. Jubilee stayed hidden and, while living in the underground base, the mutant known as Gateway was the only person aware of Jubilee's existence. During her stay in the base, Jubilee stowed away in Dazzler's quarters and found an immediate kinship, in the extent of Alison Blaire's wardrobe. Jubilee stole food and borrowed clothes from several of the X-Men to create a makeshift costume for herself. Jubilee was present when Nanny and Orphan-Maker ambushed the X-Men at their base, but simply hid while the battle ensued. Once while the X-Men were out, Jubilee was harassed and hounded by a Reaver guard dog that was left at the base. Jubilee stayed in hiding until the X-Men had abandoned the base, and their enemies the Reavers had captured Wolverine and taken over the base.

While sneaking around the caverns in the outback base, Jubilee was startled to find Wolverine hung up on a cross and near death. Jubilee helped Wolverine get down from the cross, and nursed him back to health. Afterward, she teamed with Wolverine on several of his missions throughout the world. During this time she held her own against The Hand and blew up a section of the Mandarin's castle with her powers while being held prisoner there with Wolverine and Psylocke.

Jubilee and Wolverine grew a close father-daughter relationship with one another. Jubilee needed the guidance of a parent, while Wolverine needed the peace and joy of a child. Due to this relationship, Jubilee was referred to as Wolverine's unofficial sidekick. The duo teamed up to fight Sentinels, Omega Red, Sabretooth, Sauron, and even sought revenge on Reno and Molokai for the murder of her parents.

After hearing of mutants being attacked on the island nation of Genosha, the trio made their way there. They met Boom Boom and Rictor, who had lost their powers. Leaving Jubilee to guard the depowered mutants, Wolverine and Psylocke attempted to invade the Genoshan Magistrate headquarters, but were captured. The three young mutants escaped capture, and helped the other X-Men defeat Cameron Hodge. Upon returning to the United States, Jubilee joined Storm, Wolverine, Psylocke, Forge, Banshee, and Gambi as a member of the X-Men. Although she accompanied them on many of their missions, they remained wary of placing her in harm's way because of her young age. When Wolverine was kidnapped by The Hand, Jubilee argued that she should be allowed to help (as she had previously fought and defeated The Hand), and found an unlikely ally in Psylocke. After run-ins with the Skrulls, the Brood, Omega Red, and Mojo, Jubilee was finally made to stay at the mansion by the X-Men, and was not permitted on missions anymore due to her age.

When Professor X was almost killed by a villain named Stryfe, who appeared to be Cable, the X-Men were quick to suspect Cable of the deed. It was Jubilee who persuaded the X-Men that he might not be the culprit, as no one knew what Stryfe really looked like, and he could therefore be disguised as Cable. Once Professor X was cured and regained the use of his legs for a short time, Jubilee took him rollerblading to cheer him up. After spending some time bonding with him she realized that he wasn't the stuffy old man she took him for, and they grew closer. After his legs began to weaken, Jubilee helped him back into his wheelchair, realizing that just being there to help meant more to him than anything she could say. Some time later Jubilee accompanied Wolverine to their old base in Australia. Their arrival set off a dormant Sentinel, whose attack interacted with Gateways portal and sent Jubilee back in time to her parents' house just before they were killed. Certain she could save them from dying in the car crash, she convinced them not to go when the doorbell rang. At the door stood two armed hit men, Reno and Molokai, who took her parents away at gunpoint. Learning for the first time that their car accident had been faked, and that they had in fact been murdered, Jubilee swore revenge. Upon returning to the present she tracked the two hit men down, with Logan backing her up the entire time. But once she had her parents' killers at her mercy, she found that she couldn't bring herself to kill them, a revelation that pleased Logan.

Back at the mansion Jubilee became close friends with Colossus's little sister Illyana. When Illyana was diagnosed with the Legacy Virus, Jubilee spent all of her time at Illyana’s bedside. When Kitty Pryde arrived, Jubilee was jealous of her at first, because she was Wolverine's first sidekick, but the two soon formed a friendship. Despite all their attempts, the X-Men were unable to save Illyana. Jubilee takes her death extremely hard, almost as bad as Colossus. Several weeks later, after Magneto violently removed the Adamantium from Wolverine's skeleton, Logan decided to leave the X-Men, fearing that he was a liability to them. Knowing how much this would affect Jubilee, he wrote her a touching goodbye letter and left his favorite cowboy hat for her. A short time later, Sabretooth was brought to the mansion by Professor X and held in captivity there. Jubilee was terrified of him, and had nightmares of him killing the X-Men and leaving her for last. Attempting to get over her fears she began to bring food to Sabretooth, who taunted the poor girl mercilessly. One night her nightmares almost came true when the mansion's security system went down and Sabretooth escaped from his cell. He hunted the X-Men throughout the mansion, but in the end it was Jubilee who took him down with a neutralizer pistol.

With the other X-Men busy, Banshee was the only person to notice that Jubilee was having trouble coping with Wolverine's absence, as well as all that had happened to her since he left. When the Phalanx assimilated most of the X-Men, Jubilee and Banshee were forced to team up with Sabretooth and the White Queen, Emma Frost (who had recently awoken from a coma in the mansion's medical facility), to escape from them. This unusual group worked together to gather all the young mutants listed by Professor X as future allies. The Phalanx was later defeated thanks to the sacrifice of a young mutant girl named Blink.

Jubilee later accepted the invite to the mutant-only island of Krakoa.
