Jordan White, editor over at Marvel just tweeted the following picture, which, although taken out of context, is pretty straightforward nonetheless.
Boom! You heard it here first! Actually, no you didn't, credit where credit is due, CBR broke this news. Ok? I admitted it. Hell of a website. Hell of a website.
In any event, this move makes a lot of sense, given how great Domino was represented by Zazie Beetz in Deadpool 2. Most people didn't even know who Domino was before DP2, but they definitely do now; she was almost better than Deadpool himself, and their friendly back and forth was one of the highlights of the film.
Domino is best known (both before DP2 and after) as a member of the mutant team X-Force, which was created by Fabian Nicieza (writer) and artist/co-writer Rob Liefeld, the man who can draw huge breasts, but feet elude him. Domino made her first major appearance in X-Force #8 in March of 1992 as an original member of the Wild Pack team led by the mutant Cable. She is a deadshot with most guns, and has a psionic/telekinetic ability to alter probability of whatever she's looking at, often described as giving herself "good luck" and her enemies "bad luck." As shown in the film, it's a pretty kickass power to have.
