text: Replacement When Cable became the leader of the New Mutants following their break from the X-Men, a mutant named Copycat impersonated Domino and joined as his field leader and stayed with the team as they changed from the New Mutants to X-Force. When it was revealed that the real Domino was actually a prisoner of the supervillain Tolliver for over a year, X-Force rejected Domino's imposter and, with Cable's reassurances, planned to rescue the real Domino and welcome her onto the team.
  Meanwhile, the real Domino learned of Tolliver's destruction of X-Force's Adirondack base and planned her escape. Cable found her at Tolliver's Italian home, along with her apparently murdered double. Domino was accidentally freed by Deadpool, whom she shot. Cable sent her to find X-Force. She escaped on Tolliver's helicopter and survived a fall from Tolliver's helicopter into the sea. She found X-Force and joined the team.
  Joining X-Force
  Domino stayed with the team for most of its existence, becoming its de facto leader when Cable left the team on several occasions. For a while, she was a prisoner of the forces of Bastion, which severely affected her mentally and physically. During X-Force's existence, Domino had several solo adventures. During one, she was forced to kill her mentally ill, ex–Six Pack partner Grizzly.
  X-Corporation
  When X-Force briefly disbanded, Domino joined the X-Corporation. While working in their Hong Kong branch, Domino's partner, Risque, was murdered and she summoned the core group of the X-Men to help investigate. Together the mutants uncovered the truth behind John Sublime's "Third Species" movement: he was harvesting body parts from living mutants to create his U-Men. They also helped free the mutant named Xorn.
