History: Very little is known about the early life of the woman now known as Domino. Even her original, given name is shrouded in mystery. What is known is that she has had a long and distinguished career in many fields of covert activity, both as an agent of various organizations and governments, and as a freelance mercenary. In one of her earliest recorded exploits, Domino was assigned to bodyguard a man named Milo Thurman, a genius prodigy in predicting world events and shifts in the balance of power between governments, from terrorists interested in his abilities. In the course of this assignment, she and Thurman fell in love. It was Thurman who coined her nickname "Domino" (referring to her white skin and black dot around her left eye), which became her longtime codename. He also called her Beatrice, after a character in his favorite book, Dante's Inferno, and she continues to use that alias today in her plainclothes identity.

Thurman and Domino's relationship, however, was destined to be short-lived, as a raid by the subversive organization A.I.M. on the government facility where Thurman was being held forced Thurman into even deeper government cover. His government superiors told Thurman that Domino was dead.

An unspecified amount of time later, Domino joined the mercenary group called the Six Pack. It was here that she met the man known as Cable, and developed the beginning of a long and intimate friendship with him. One of the clients of the Six Pack was an arms dealer named Tolliver, who was actually Cable's estranged (and time-displaced) son Tyler.

Several months later, Cable gathered together a group of young, disenfranchised mutant heroes to form the strike team called X-Force. A woman purporting to be Domino helped Cable found the team, and participated on several missions with them. In actuality, the real Domino had been taken prisoner months before by Tolliver, as part of a vendetta against his father, Cable. Tolliver hired a mutant shapeshifter named Vanessa Carlyle, a.k.a. Copycat, to infiltrate X-Force.

The members of X-Force discovered "Domino's" treachery, but not before Copycat managed to cause the destruction of X-Force's first base. Cable himself freed Domino from her captivity on Tolliver's estate, and through a series of trials and tribulations, Domino and Cable became, in effect for the first time, co-leaders of X-Force.

Domino remains in her capacity as X-Force's co-leader. Recently, Milo Thurman, who still believed Domino to be dead, and was still in government custody, was taken hostage by Donald Pierce and Lady Deathstrike, who intended to siphon away Thurman's uncanny instincts and knowledge of world trends for Pierce's own purposes. Domino found out about the abduction, and tracked Thurman and the Reavers to Pierce's new base in the old "Weapon X" project in Canada. Domino defeated Pierce and Deathstrike, and laid waste to Pierce's base, but was unable to save Thurman in time from the fatal effects of Pierce's information transfer process. Pierce has apparently managed to siphon off at least a portion of Thurman's strategic brilliance into his cybernetic memory banks, but to what extent remains to be seen.

Domino soon returned to X-Force, but eventually left the group as they drifted from their paramilitary beginnings. She returned to help the team on occasion, such as in defeating the Blob who was acting on behalf of the menace known as Onslaught. When Cable was not part of the group, Domino often acted as the de facto leader of X-Force.

Later, during the government-sponsored mutant-hunting program called Operation: Zero Tolerance, Domino was captured and tortured by Ekatarina Gryaznova, who was transformed into a cybernetic Prime Sentinel through the Operation: Zero Tolerance program. Gryaznova was a part of a rogue CIA faction that Domino had destroyed during one of her past exploits, and Gryaznova sought revenge. She confronted Domino what is to believed to be her past history, but Domino referred to it as "at least 80% wrong." Domino escaped but learned she was implanted with a device that disrupted her mutant powers over probability. About the same time, Domino was sought by the mutant Jesse Aaronson, who agreed to help Domino track down Gryaznova (now known as Gryphon) if she would help him find his brother. The two failed and Domino was captured. Jesse then asked for help from Domino's former teammates, X-Force, who helped Jesse rescue Domino. The two joined X-Force, and soon battled Jesse's brother and his team of mutants called the New Hellions.

Eventually, Domino left X-Force to return to freelance mercenary work. She later was possessed by the alien Aentaros so that she could kill its enemy, Randall Shire. Cable confronted her and managed to thwart Aentaros' plan. Later still, Domino was targeted by the assassin Marcus Tsung, whose power could slay a person with a simple look. Domino sought X-Force's help, and recovered with help from an alien organism that had attached itself to her. X-Force defeated Tsung and the alien organism but was believed to have died during the process.

Domino parted ways with X-Force, but later sought the team's help to take down the mutant assassin Marcus Tsung -- capable of killing on sight, through act of will alone. Tsung had attempted to murder Domino, but she recovered thanks to the bio-organic alien organism attached to her body at the time. X-Force managed to defeat Tsung, albeit barely, and Domino remained with the squad as field controller until her teammates appeared to die in a cataclysmic battle.

However, Domino and other members of X-Force reappeared to challenge the current government-sponsored X-Force over a dispute from the common name. Domino and her teammates escaped after the encounter.
