Domino (Neena Thurman) is a Marvel Comics character, best known as a member of the X-Men offshoot X-Force. Created by writer Fabian Nicieza and artist/co-writer Rob Liefeld, she first fully appeared in X-Force, vol. 1 #11 (June 1992).
In addition to her exceptional marksmanship and hand-to-hand skills, Domino possesses mutant probability-altering powers, similar to those of the X-Man Longshot. She often uses her skills as a mercenary, but has also been the partner, confidante, and lover of the superhero Cable, a lieutenant in his militant group X-Force, and a member of the X-Men.
