9 Reasons An X-23 Movie Needs To Happen
4. It Can Setup The X-Force Movie
An X-Force movie is in the works and will happen eventually, though there's still a lot up in the air about how exactly it will tie into the other X-Men movies, other than its leader Cable first appearing in Deadpool 2, which will presumably provide some sort of tacit lead-in.
X-23 has been a prominent member of the X-Force in the comics, so it'd be leaving money on the table not to have her join the group for the movie.
X-23's solo film could act as a bridging vessel of sorts, possibly with a post-credits scene where Cable shows up to recruit her. Yes, it begs a million questions about timelines and Cable's time-traveling capabilities in particular, but given the slippery logic of the entire franchise, this really feels like the most sensible way to go.
