Zazie Beetz as Domino. She is a member of the mutant team X-Force. In addition to her exceptional marksmanship and hand-to-hand skills, Domino possesses mutant probability-altering powers. 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. She see you as tiny boy, not bigger than her little finger.
