After years of waiting, "X-Men: Apocalypse" is just about ready to take over theaters across the country. The film is the third in a time-tossed trilogy started back in 2011 with "X-Men: First Class," and it's the sixth "X-Men" team film overall. Not only does the movie mark what could be the end of the story of Magneto, Mystique and Professor X, it also sets up a whole new generation of mutants -- ones with very familiar names.

RELATED: Revisit CBR's Complete Coverage of "X-Men: Apocalypse"

Cyclops, Storm, Jean Grey and Nightcrawler are all back in the mix, and prominent mutant villain Apocalypse is making his big screen debut as well. With so many mutants -- good and evil -- appearing in director Bryan Singer's newest X-movie, CBR has put together a quick guide to catch you up on where we last saw all these characters and what we know about the movie so far. Here's "X-Men: Apocalypse," A to X.

A is for Angel





Considering how closely the two characters are tied in the comics, you can't have a movie about Apocalypse without Archangel. Thankfully, Ben Hardy has stepped into the role as the razor-winged Horseman. We last saw Angel back in the original -- and now out of continuity -- X-Men film trilogy; Ben Foster played the feather winged Warren Worthington III in 2006's "X-Men: The Last Stand." This time around, though, it's Angel's more dangerous, Archangel persona that's onscreen; Apocalypse outfits the mutant with deadly razor wings capable of shooting sharp flechettes.

B is for Beast





Nicholas Hoult's brilliant and sometimes blue Beast has been one of the mainstays of the latest trilogy of X-Men films, which concludes with "X-Men: Apocalypse." Hoult previously appeared as Hank McCoy in 2011's "First Class" and 2014's "Days of Future Past," where he served as the team's big brain. This time around, it looks like Beast will show off more of his brawn, as trailers have shown the furry and furious mutant going up against the Horseman Psylocke. And yes, B is also for Beast Mode.

C is for Cyclops





Set in 1983, "X-Men: Apocalypse" will reintroduce a number of characters into the X-Men franchise -- albeit this time as teenagers. Tye Sheridan's Cyclops is among the film's new recruits, and this Scott Summers is considerably younger than the adult played by James Marsden in the original trilogy. The film will also explore the relationship between Scott and Jean Grey, which might evolve over multiple pictures. Yep, Sheridan's signed on to do more than one "X-Men" movie.

D is for Director





"X-Men: Apocalypse" marks Bryan Singer's fourth outing as director of an X-Men movie. Singer kicked off the franchise with 2000's "X-Men" and followed that up with 2003's "X2: X-Men United." After stepping away for two installments ("Last Stand" and "First Class"), Singer returned with 2014's "X-Men: Days of Future Past." Singer's gone all-in on the film's religious aspects, describing Xavier as a "Christ figure" and Apocalypse as a "false god." Whether or not Singer will return for another film is still TBD, but if he does, he's hinted that he wouldn't mind going to space.

E is for En Sabah Nur





Oscar Isaac's following up his fan-favorite role as "Star Wars'" Poe Dameron with a completely different character: the all-powerful Ancient Egyptian mutant known as En Sabah Nur, or Apocalypse. This villain, who has amassed a powerful arsenal of mutant powers over the centuries, has left his mark on history with some even believing him to be the Biblical god of the Old Testament. This time around, the X-Men aren't facing bigoted humans or giant robots; they're facing a seemingly immortal mutant with unheard of power levels and a desire to bring about, appropriately enough, the Apocalypse.

F is for Fassbender





Michael Fassbender returns for his third film as Magneto, the Master of Magnetism. Unlike the previous two films, though, "X-Men: Apocalypse" finds Erik Lehnsherr doing someone else's dirty work. Magneto suits up as one of Apocalypse's Four Horsemen, interrupting what looks like a reclusive period for the future champion of mutantkind. That period of hiding comes to an end, however, when Erik reveals himself as a mutant and gets a power upgrade from Apocalypse.

G is for Gambit





The Ragin' Cajun X-Man has his own movie in development starring Channing Tatum, and the actor was even rumored to have a cameo in "Apocalypse." Tatum denied those rumors, and they've since fizzled out. Still, Gambit was one of Apocalypse's Horsemen in the comics, so it's not far-fetched to believe he could show up in the movie. Although right now it seems like Tatum and the "Gambit" crew are working toward getting the card-throwin' X-Man's solo movie off the ground.

H is for Havok





Lucas Till's Havok has been a player in all three installments of the X-Men's time-hopping trilogy, but he's had a notably smaller role than Xavier, Magneto, Mystique and Beast. After being introduced as one of Charles Xavier's original X-Men in "First Class," he was seen briefly as a soldier in Vietnam in "Days of Future Past." Judging by trailers for the film, Havok might have more of a presence in this film; after all, he's by Xavier's side when he gets the rundown on Apocalypse from Moira MacTaggert. This film also introduces Havok's brother Cyclops into the mix, marking the first time the Summers siblings have shared the screen.

I is for International Box Office





"X-Men: Apocalypse" is already a money maker -- and it hasn't opened in America yet. The film opened last weekend on 20,596 screens in 75 markets, ranging from the UK to Brazil, Russia, Mexico, India and many more. The film gave Fox its largest ever opening weekends in the Philippines, India, Indonesia, Singapore, Thailand and Colombia. The film's worldwide haul so far stands at $103.3 million, and it opens in the U.S., China and South Korea this week.

J is for Jubilee





Jubilee had three blink-and-you'll-miss-'em cameos in the original X-Men trilogy, where she was played by Katrina Florence and Kea Wong. Lana Condor steps into the yellow coat and pink sunglasses in "Apocalypse," playing a version of the character with electrical "fire-plasmoid" powers as opposed to pure fireworks powers. Condor also hosted a retro-style enrollment video for the Xavier's School in-character as Jubilee, and it's totally rad.

K is for Kinberg





"X-Men: Apocalypse" marks the fourth film that Simon Kinberg has been involved with. In addition to writing and producing "Apocalypse," he also wrote and produced "Days of Future Past," produced "First Class" and wrote "The Last Stand." Kinberg also, in a way, serves as Fox's version of Marvel Studios president Kevin Feige; Kinberg has been involved in many of Fox's Marvel properties, also serving as a producer on "Deadpool" and writer/producer on "Fantastic Four." He's also onboard for the upcoming third "Wolverine" film and "Gambit."

L is for Logan





Surprise -- Wolverine is in this film! Director Bryan Singer remained purposefully vague about Logan's involvement in the movie for a long time before the final full-length "Apocalypse" trailer confirmed that Wolverine will be in the film. But this time around, Hugh Jackman is playing a version of the character we haven't seen before. When we last saw the character in "Days of Future Past," the 1973 version of Logan was being fished out of a river by the government (well, Mystique posing as General Stryker fishes him out). "Apocalypse" will see Wolverine at his most feral, in the moments following his transformation into the metal-boned killing machine Weapon X.

M is for Mystique





Along with Magneto and Professor X, Mystique's journey from frightened runaway to deadly free agent has played a major role in this trilogy of X-Men films. "X-Men: Apocalypse" will put Jennifer Lawrence's shape-shifter right in the center; we've seen in various trailers and even a scene that she's responsible for pulling together a team of X-Men to combat Apocalypse and his Horsemen. She also gives the mutants a stirring speech, proclaiming that the teenage mutants have become X-Men. Mystique spent the last two films shifting her allegiance from one side to another, but this time around she seems to be fully on board with the heroes. Whether or not we'll see Lawrence as Raven again remains unclear; her contract is up and she's not sure she'll return.

N is for Nightcrawler





Nightcrawler is another classic X-character making his way back to the big screen thanks to the franchise's all-new timeline and '80s setting. We last saw Kurt Wagner way back in 2003 when he teleported onscreen played by Alan Cumming. The character didn't return for 2006's "Last Stand" and he's been M.I.A. from the film franchise ever since. Now Nightcrawler is back, this time played by Kodi Smit-McPhee. How big of a role Nightcrawler plays in the film isn't known, but we've seen his first encounter with Mystique already and we know he rocks a Michael Jackson "Thriller" jacket too. And on top of that, he's not used to brain freezes.

O is for Ororo Munroe





After playing Storm for four films spanning from 2000's "X-Men" to 2014's "Days of Future Past," Halle Berry has passed the lightning cloud on to Alexandra Shipp, who debuts as the young Ororo in "Apocalypse." This time around, though, we're seeing a younger and edgier Storm, one that even sports the character's punk-inspired Mohawk look from the '80s "X-Men" comics. Shipp's Storm also won't be fighting alongside the X-Men, either; instead she's one of Apocalypse's Four Horsemen. But, if you're looking for spoilers, some have made it online that hint at Storm's final fate.

P is for Psylocke





Olivia Munn and Psylocke are basically inseparable at this point. Not only has Munn praised her character -- a mutant assassin with deadly mental powers -- profusely, but she's posted tons of fight training and sword swinging Instagam videos. Producer Simon Kinberg recently revealed that Psylocke was added to the movie relatively late in pre-production once they realized that they needed a fourth full-time Horseman. Munn's "Deadpool" audition and some fan art then convinced him that Psylocke would be the character to add. Psylocke's a major X-Man in the comics, and "Apocalypse" marks her true film debut following a fleeting cameo in "Last Stand."

Q is for Quicksilver





Evan Peters' speedster stole the show in "X-Men: Days of Future Past" with an audience-pleasing slow-mo scene. "Apocalypse" finds Quicksilver back in action again, this time as a full-fledged member of the team as opposed to a hired hand. "X-Men: Apocalypse" will also fully deal with a plot point that was only hinted at in "Days of Future Past": Magneto is Quicksilver's father. Besides appearing again in "Apocalypse," Quicksilver has also become a surprising spokesman for a number of products, including energy drinks, cars and internet services.

R is for Rose Byrne





After being absent from "X-Men: Days of Future Past," Rose Byrne's C.I.A. agent Moira MacTaggert returns in "X-Men: Apocalypse" to drop some needed exposition on Xavier. 21 years have passed in continuity since we last saw secret agent MacTaggert at the end of "First Class." That film ended with Charles Xavier erasing Moira's mind of recent events, including the location of his newly established school. What's happened to her character in the decades in between "First Class" and "Apocalypse" is not yet known, although it looks like she's still with the C.I.A.

S is for Sophie Turner





Along with Cyclops, Storm and Nightcrawler, Jean Grey is another A-list X-Man returning to the franchise as a teenager. "Game of Thrones'" Sophie Turner takes over the role from Famke Janssen, who previously appeared in the first "X-Men" trilogy and had cameos in "The Wolverine" and "Days of Future Past." Turner says her telepathic teen is much more isolated and alienated this time around, and there's also something darker lurking within her. X-Men fans should keep a look out for flashes of the Phoenix in this film, as Turner, Kinberg and Singer have all hinted that Jean Grey-centric "Dark Phonix Saga" could inspire the next X-Men film.

T is for Timeline





"X-Men: Apocalypse" is set in 1983. This follows a tradition of jumping through decades that was established with "X-Men: First Class." That film was set in 1962, and it's follow-up "X-Men: Days of Future Past" was set in 1973. And yes, the next "X-Men" film, which hasn't been officially announced yet, will take place in the '90s. Additionally, "X-Men: Apocalypse" is the first film set in the franchise's new timeline. "X-Men: Days of Future Past" was a time-travel epic, one that brought the cast from the first X-Men trilogy together with the younger characters from "X-Men: First Class." During "DOFP," a time-traveling Wolverine definitively altered history and created a new timeline -- which is the timeline that "Apocalypse" is set in. Make sense? That's why this film is able to introduce previously seen characters like Nightcrawler, Storm, Jean Grey and Cyclops in a totally new way.

U is for Uniforms





Despite their potentially spoilery nature, the team's colorful costumes have been prominently featured in magazine photo shoots and TV spots. But we now know that the X-Men wear costumes that aren't their all-black body armor, which is what they're sporting in pretty much every other poster and trailer. These individualized looks are the closest the films have ever come to the comics; Cyclops, Jean Grey and Storm are all wearing what look like modifications of the costumes Jim Lee designed back in 1991, and Nightcrawler's wearing his classic red and black getup. "X-Men: Apocalypse" is the film that finally brings the comic looks to the big screen.

V is for Villains





"X-Men: Apocalypse" is all about the villains. That's appropriate considering that the film is named after the villain, which is the first time that's happened in the X-Men film franchise. And not only does the film have Apocalypse, but the film also features his dangerous Horsemen: Storm, Angel, Psylocke and Magneto. Each of them has been given a power boost and a new mission, but they've also fallen under the sway of Apocalypse -- a villain described as a fanatical cult leader.

W is for Weapon X





Even before it was confirmed that Wolverine would have a part to play in "Apocalypse," it was revealed that one scene in the movie would take place in the Weapon X facility. This is the mutant soldier factory that birthed Wolverine, coating his skeleton -- and bone claws -- in the indestructible metal known as adamantium. The facility was previously seen in 2003's "X2" and 2009's "X-Men Origins: Wolverine." The latter told the tale of how Logan became the metal-clawed Wolverine. The timeline-reset means that, yes, we get to see these events unfold in a slightly different way, and we'll get to see a Wolverine that's unlike anything we've seen before; producer Simon Kinberg called him "violent" and "visceral."

X is for Xavier





James McAvoy takes the lead as Charles Xavier for the third time, completing a trilogy started with 2011's "X-Men: First Class." This time around, Xavier will confront an evil unlike any he's ever faced before, and he'll come face to face with what may be the first mutant ever. Of course that mutant is Apocalypse, and Apocalypse doesn't treat Xavier very well at all. Most importantly, though, "Apocalypse" will see McAvoy take on Xavier's most iconic characteristic: his hairstyle. Or rather his lack-of-hair style. The film even documented McAvoy's transformation into the bald leader with a behind-the-scenes featurette.

"X-Men: Apocalypse" opens in U.S. theaters May 27.
