Personality: Jubilation is a reluctant hero who doesn't like putting herself at risk for the benefit of her friends, let alone people she doesn't know. This gutsy, outgoing teenager is quick on her feet and always enthusiastic. She is adventurous and very capable of fending for herself. She sees Wolverine as a parental figure in her life-if there's anyone she would put herself at risk for, it would be him.

Strength: Jubilee possesses the normal human strength of a girl of her age, height, and build who engages in intensive regular exercise.

Fighting Skills: Training in hand-to-hand combat, combined with Acrobatics.

Special Skills and Abilities:Jubilee has a fair amount of skill at throwing her fireworks, and is an acomplished skater.

Known superhuman powers: 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.

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.

Then 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.

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.
