Looks like Cable won’t be the only mutant joining Ryan Reynold's Merc With a Mouth in Deadpool 2. According to Heroic Hollywood, sources at Fox have told them (so, grain of salt) they will also introduce Neena Thurman, aka Domino, in the superhero movie sequel.
In the Marvel comics, Domino not only has ties with Wade Wilson, but she’s also had a long history with time-traveling mutant Nathan Summers, aka Cable. She was not only his teammate, but also his lover. She was a former mercenary who gained mutant-like probability-altering powers, meaning she could manipulate luck, as part of a government experiment called Project: Armageddon, of which she became one of two survivors.
An expert markswoman and soldier with awesome hand-to-hand skills, Domino turned her mercenary powers to good and became a member of the X-Men, as well as X-Force. Which is where it becomes interesting, because we know that Ryan Reynolds is trying to get the ball rolling on that long-rumored X-Force movie.
Also interesting is Domino’s connection to Vanessa Carlysle (played by Morena Baccarin on Deadpool). In the comics, Vanessa is actually a shape-shifting mutant called Copycat (although she doesn’t appear to be one *yet* in the movie) whose very first appearance was as Domino in The New Mutants #98 in 1991. However, the real Domino did not appear until X-Force #8, well over a year later, in 1992.
If Domino does indeed make her big-screen debut in Deadpool 2, I'm looking forward to all the zany banter between her and Deadpool, since Domino is considered quite the witty character herself.
