Who is domino in deadpool 2

Domino (Neena Thurman) is a fictional character appearing in American comic books published by Marvel Comics. The character is best known as a member of the mutant team X-Force. Created by writer Fabian Nicieza and artist/co-writer Rob Liefeld, Domino made her first full cover story appearance in X-Force #8 (March 1992) as a past member of the Wild Pack, later renamed Six Pack.

In addition to her exceptional marksmanship and hand-to-hand skills, Domino possesses mutant probability-altering powers, similar to those of the mutant Longshot. She often uses her skills as a mercenary, but has also been the partner, confidante, and love interest of the superhero Cable, a lieutenant in his militant group X-Force, and a member of the X-Men. Domino is played by Zazie Beetz in the film Deadpool 2.
