"If at first you don't succeed, try, try again." It's this old maxim, but one very much applicable to 20th Century Fox's developments with the X-Men franchise. Audiences previously saw a not-so-great adaptation of Chris Claremont's classic Dark Phoenix Saga in 2006 with Brett Ratner's X-Men: The Last Stand, but that was before the Days of Future Past reboot. Now the movies are ready to take a second whack at the story, specifically with Simon Kinberg's X-Men: Dark Phoenix.

We know that the series will see another decade jump for the narrative after X-Men: Apocalypse, with the action set in the early 1990s, but who should fans expect to see in the upcoming blockbuster? In hopes of answering that pressing question, we've put together this feature to keep track. Below and on the next few pages we've cataloged all of the confirmed heroes and villains set to appear in the movie, so read on and learn a bit about the 2019 film.

Jean Grey X-men Dark Phoenix
Jean Grey a.k.a. Phoenix
One could argue that the greatest mistake made by X-Men: The Last Stand was not telling the story through the eyes of Jean Grey -- instead opting to make Hugh Jackman's Wolverine the protagonist. Thankfully, this will not happen with X-Men: Dark Phoenix, as it's been confirmed that Sophie Turner's version of the telepathic telekinetic will be the central character in the movie.

Developing as a much more faithful adaptation of the comics, Jean Grey will be on a space mission at the start of X-Men: Dark Phoenix, but everything will start to go wrong when they encounter a mysterious cosmic force. It's a serious disaster, but, more importantly, the incident awakens something within the young mutant, as she starts to see her powers grow stronger and stronger -- to the point where she becomes seriously dangerous. This is the emergence of the Phoenix, who in the comics is one of the most powerful beings in the universe, with the ability to open stargates, destroy matter at the subatomic level, and generate cosmic fire amongst other things. Despite Jean's moral heart, she becomes an incredible threat that Professor X and his team must deal with.

Cyclops X-Men Apocalypse
Scott Summers a.k.a. Cyclops
As a member of the X-Men, Cyclops (Tye Sheridan) will obviously be very much tied up in all of the action discussed -- but, as fans know, there is an important emotional factor in the whole thing for him. Scott Summers is not just a key member of Professor X's team, but the true love of Jean Grey. We only witnessed the characters first meeting and starting to get to know one another in X-Men: Apocalypse, but X-Men: Dark Phoenix will be set a full 10 years after those events, and that's a lot of time to develop a deeper relationship.

Of course, being in love with Jean Grey as she turns into Phoenix should ultimately provide some serious moral conundrums for Cyclops, especially as she becomes too powerful and dangerous. If the film addresses the idea of killing her before she gets too out of control, Scott might be a serious roadblock in terms of getting the horrible deed done. If not, the other possibility is that we see him make a terribly sad sacrifice.

Storm X-Men Apocalypse
Ororo Munroe a.k.a. Storm
Played by Alexandra Shipp in X-Men: Apocalypse, Ororo Munroe a.k.a. Storm had a complex re-introduction to the franchise post-Days of Future Past. Rather than being introduced as a hero, her first scene in the film instead saw her bend the knee for the titular villain and agree to serve as one of his Four Horsemen. The good news is that by the end of the film she had a serious change of heart, deciding to join the X-Men in battle, and presumably that's what she has been doing for the last 10 years when we catch up with her in X-Men: Dark Phoenix.

While there isn't a great deal known about her specific role in the narrative of the film, it will be interesting to see how her powers have developed. In the comics Storm is one of the most powerful mutants alive (being able to control the weather is kind of a big deal), but we have not yet seen this fully explored on the big screen yet. Going up against some scary threats in X-Men: Dark Phoenix, the Goddess of the Plains may find her moment to demonstrate the full scale of what she can do.
