The current comics Wolverine may be appearing in the third Logan movie as a new rumor says X-23 is on the way.
According to Superhero Hype, X-23 will appear in the movie along with Wolverine and Professor X:
Itâ€™s been known for some time that the upcoming Wolverine 3 will feature Hugh Jackmanâ€™s Logan and Patrick Stewartâ€™s Charles Xavier teaming up, but there may be another X-Men character along for the ride in the film. Though it remains unconfirmed, weâ€™ve heard that the mutant X-23 will be making her feature debut and will join Wolverine and Professor X for their journey in the sequel.
Although she was created in an animated series, X-23 has become a regular in Uncanny X-Force and most recently the core X-Men comics. After they killed off Wolverine in the “Death of Wolverine” story line, X-23 took on the mantle of Wolverine and stars in the current “All-New Wolverine” on-going series.
Introducing her in the third Wolverine movie could also be a way for them to pass the torch from Hugh Jackman to a new Wolverine.
