Domino

The woman who would become known as Domino was actually the result of a top-secret government breeding program intended to develop the perfect weapon, the clandestine super-soldier program Project Armageddon. There she was subjected to tests by Dr. Rossini, which included at one point being given a cat she named "Christmas". Domino was the only test subject to survive, but her "luck" power was deemed a failure to meet the project's goals. Domino's biological mother broke her out of the project and left her with Father Rudolpho Boschelli, in the Church of the Sacred Heart in Chicago. Domino eventually escaped from the Church and became a mercenary.

Later, while working for the NSA, Domino was assigned to guard the genius Dr. Milo Thurman, whose analytical ability made him too dangerous for the government to let him roam free. Over time, Domino and Thurman fell in love and were married. Thurman had a thing for Dante's "Inferno" and called Dom "Beatrice". The two separated after a raid on the facility by AIM, with Milo believing Domino had been killed during the altercation.
