She ended up being introduced in The Uncanny X-Men #130, which is right at the beginning of The Dark Phoenix Saga and as you can imagine, she didn't really fit that storyline really well.
Synopsis: This is the story of one of the X-Men's most beloved characters, Jean Grey, as she evolves into the iconic DARK PHOENIX. "There was rewriting being done all the time". But it could theoretically have an extra scene after or during the credits just to give the series a longer sendoff - "Dark Phoenix" is, after all, the work of writer/director Simon Kinberg, who has been involved with these movies for more than a decade now. That backstory is embedded in Jackman's and Stewart's textured and heartbreaking performances, discernible even to one hasn't seen a single other "X-Men" movie. By comparison, Wolverine's had an entire trio of films dedicated to him, and all of the other X-Men movies have revolved around Xavier and Magneto (Michael Fassbender) to the point that it's often felt as if filmmakers don't understand that there are other X-Men stories to be told.
You can check out our own review of Dark Phoenix here, where we said "although not the trainwreck some may have feared given its mostly lackluster trailers, Dark Phoenix nevertheless brings the long-running X-Men franchise to a close in a messy and muddled fashion". Sophie Turner, Tye Sheridan, and Jessica Chastain looked completely baffled by what they're supposed to be doing in any given moment. Not only was the film going to bring the story of Charles Xavier's mutant heroes to an end, it was going to do it by revisiting one of the most contentious, intricate parts of the X-Men mythos. Even Singer's movies have some range; Days of Future Past and X-Men: Apocalypse embrace a comics-like palette of bright blues, pinks, and purples, contrasting with the grounding of his first two films.
If you're still scratching your head because time is a polarizing thing especially when Marvel has their hands in it, here's an exact timeline of all of the X-Men movies.
Dark Phoenix is better than The Last Stand; it's not as overstuffed or coarse.
While I left Dark Phoenix pretty disappointed, there was one Easter Egg included that made me more excited than pretty much anything else in the movie. The assumption is quickly proven wrong as Jean starts having complications back home and wrestles to keep her own psychic mutation powers in check. Turner convincingly conveys Jean's conflict as she teeters between good and evil. He also wanted the movie to be about Jean's evolution only.

Dark Phoenix does have a few elements similar to Civil War.
Bafflingly, the significant bit of Phoenix-centric groundwork that was laid out in X-Men: Apocalypse goes unaddressed, in favour of a subplot that draws inspiration both from Marvel's comics and from X-Men: The Last Stand. Dazzler can be a silly character, but that doesn't mean we can't enjoy it.
It's so bad, Dark Phoenix herself (someone named Sophie Turner) actually says, "When I lose control, things happen..."
Rating explained: "Dark Phoenix" is rated PG-13 for some dark and violent action content, as well as scattered profanity, including a single use of the "F-word" that feels odd for a comic book movie.
"Dark Phoenix" is set in the early '90s.
