Marvel' heroes!!!: X-Man

In the future, robots known as Sentinels are exterminating all mutants, as well as humans who seek to help them. A band of mutants evades the Sentinels with the help of Kitty Pryde, who has the ability to project a person's consciousness into the past. Pryde's group convenes with Storm, Wolverine, Professor Xavier, and Magneto at a monastery in China. Pryde sends Wolverine's consciousness to 1973 to prevent Mystique from assassinating Bolivar Trask, the creator of the Sentinels. Following the assassination, Mystique was captured, and her DNA was used by Trask's company to create Sentinels, whose ability to adapt to any mutant power makes them almost invincible. Xavier and Magneto advise Wolverine to find both of their younger selves for help.
Wolverine awakens in 1973. At the X-Mansion, he encounters Xavier and Beast. Xavier's Institute for Gifted Youngsters has closed after most of the teachers and students were drafted for the Vietnam War. Xavier, now a broken man, has been overusing a serum which allows him to walk but suppresses his telepathy. Wolverine explains his mission and persuades Xavier to help free Magneto from a prison cell beneath the Pentagon, where he is being held for allegedly assassinating President John F. Kennedy. They rescue Magneto with the help of Peter Maximoff, a mutant with superhuman speed.
In Washington D.C., Trask unsuccessfully lobbies Congress to gain support for his Sentinel program. Meanwhile, in Saigon, Mystique prevents William Stryker from appropriating a group of mutant G.I.s for Trask's research. Mystique investigates Trask's office and discovers he has been capturing mutants to use in experiments. Xavier, Magneto, Beast, and Wolverine fly to Paris to intercept Mystique. In Paris, Mystique impersonates a North Vietnamese general to infiltrate the Paris Peace Accords with Trask, who is trying to sell his Sentinel technology to communist nations. Xavier, Magneto, Beast, and Wolverine arrive as Mystique is about to kill Trask. Magneto tries to kill Mystique to ensure her DNA cannot be used for the Sentinels, but she jumps from a window. The fight spills onto the street in view of the public, allowing Magneto and Mystique to escape. During this time in the future, Pryde's control over Logan weakens, and he injures Pryde.
Trask is saved, but the world is horrified by the existence of mutants. President Richard Nixon approves Trask's Sentinel program and arranges an unveiling ceremony. Trask's scientists recover Mystique's blood from the street. Meanwhile, Magneto—who has recovered his telepathy-blocking helmet—intercepts the prototype Sentinels in transit and laces their polymer-based frames with steel, allowing him to control them. At the mansion, Xavier stops taking his serum and slowly regains his mental powers, while losing the ability to walk. Through Wolverine, Xavier speaks to his future self and is inspired to work for peace between humans and mutants once again. He uses Cerebro to track Mystique, who is heading to Washington D.C.
As Xavier, Wolverine, and Beast search for Mystique, Nixon unveils the Sentinel prototypes at the White House. Magneto commandeers the Sentinels and attacks the crowd, then sets the Robert F. Kennedy Memorial Stadium around the White House as a barricade. Nixon and Trask, accompanied by the Cabinet, Secret Service officers, and Mystique (disguised as a Secret Service member), are taken to a safe room. Wolverine and Beast try to stop Magneto, but he pits a Sentinel against them and then throws Wolverine into the Potomac River. In the future, the X-Men make their final stand as a large army of Sentinels attack the monastery. In 1973, Magneto pulls the safe room from the White House and prepares to kill Nixon and his Cabinet. Mystique, disguised as Nixon, incapacitates Magneto with a plastic gun. Xavier persuades Mystique to spare Trask and allows her and Magneto to flee. Mystique's actions are seen as a mutant saving the President, leading to the cancellation of the Sentinel program. Trask is arrested for trying to sell American military secrets.
Wolverine wakes up in the future to find Iceman, Rogue, Colossus, Pryde, Beast, Storm, Jean Grey, Cyclops, and Xavier alive. In 1973, Mystique impersonates Stryker and takes custody of Wolverine.
In a post-credits scene, a crowd chants to En Sabah Nur, who is using telekinesis to build pyramids as four horsemen keep watch nearby.

Hugh Jackman as Logan / Wolverine; a mutant with accelerated healing, enhanced senses, adamantium-laced skeleton and retractable bone and adamantium claws.

James McAvoy and Patrick Stewart as Charles Xavier / Professor X; the world's most powerful telepath.Singer described the younger Xavier as "a very different beast from First Class 's feckless playboy. He's a wounded animal, bearded, long-haired, filled with rage at the way the world has treated him." Kinberg said the film was intended to be the story of the younger Xavier beginning to "become the Professor Xavier we know" as Wolverine mentored him.

Michael Fassbender and Ian McKellen as Erik Lehnsherr / Magneto; the master of magnetism and "one of the most powerful mutants on Earth."

Jennifer Lawrence as Raven Darkhölme / Mystique; a mutant who can shape-shift. Singer said Mystique "is less innocent, evolved, getting closer to where Mystique was in X-Men 2". Given Lawrence had suffered skin irritations from the full body make-up used in First Class, the process was changed so from the neck down it would be a bodysuit. As a result, the make-up process was reduced from eight hours to three. The make-up team at Legacy Effects sculpted Mystique's scales digitally, making them shorter in size and placed in a way that they would accentuate Lawrence's face.

Halle Berry as Ororo Munroe / Storm; a mutant who can control the weather and one of the most battle-tested and powerful X-Men. Berry was asked if her pregnancy affected her role as Storm, she replied, "I wasn’t in as much as I was meant to be. My ever-growing belly was posing a constant challenge! What I could do was getting more limited so the role that I play is so different from what it could have been, due to my surprise pregnancy." According to Kinberg, Berry had another scene in the film but was cut because of Berry's limited schedule.

Nicholas Hoult and Kelsey Grammer as Hank McCoy / Beast; a mutant with super-strength, agility, and speed. Hoult plays the character in scenes set in 1973 while Grammer makes a cameo appearance as Beast in the future setting.

Anna Paquin as Marie / Rogue; a mutant who can absorb the life force and mutant abilities of anyone she touches. Kinberg wrote a shorter part for Paquin than initially planned because she did not have much time to be on-set. During post-production, Paquin's role was reduced to a cameo after most of her scenes were cut, Kinberg stated that most of her role was cut because it was a "sub-plot. It was a deviation from the main story of the film." However, she was still featured in the film's various promotional materials. Kinberg stated that an extended version of the film with all of Paquin's scenes reinstated into the film, titled the Rogue Cut will be released in 2015.

Ellen Page as Kitty Pryde / Shadowcat; a mutant who can pass through solid objects. As the youngest of the X-Men, she plays an important role in their fight for survival. Singer described Pryde as the prime facilitator and that Pryde's phasing ability enables time-travel to happen. Kinberg, when asked why Pryde is not the time-traveler in the film adaptation of the comic-book story, said, " we tried to follow the original and use Kitty, we had a problem because Ellen is 25 years old and she'd be -20 in the First Class era."

Peter Dinklage as Bolivar Trask; a military scientist and the head of Trask Industries who creates a range of robots called Sentinels, designed to find and destroy mutants. Dinklage said Trask "sees what he’s doing as a good thing—[his ambition is] definitely blind and he’s quite arrogant. He’s strove all his life for a certain respect and attention." He also said Trask is opposed by Richard Nixon. Singer said he is a fan of Dinklage and of the television program Game of Thrones, which inspired him to cast Dinklage.

Shawn Ashmore as Bobby Drake / Iceman; a mutant who can create and manipulate ice. Ashmore said about his role, "In the first X-Men I had to make a rose for Rogue but that was the extent of the character, so it's cool to see over these four movies going from that to X2—where you sort of see him do an ice wall—and in X3 he finally gets to battle, and in Days of Future Past we're soldiers."

Omar Sy as Bishop; a mutant who can absorb energy and redirect it in kinetic blasts. Sy described Bishop as the guy from the future and that he fights for survival. Singer said Bishop, along with Warpath, Sunspot and Blink, are not fresh recruits. He said, "they're more refugees that are living day to day in this hideously ruined world. They don’t have much hope in the future. They’re on the run and they join forces with the remaining X-Men to try to do this one last attempt at fixing the world."

Evan Peters as Peter Maximoff / Quicksilver; a mutant who can move, speak and think at supersonic speeds. Peters described Quicksilver as "very fast, he talks quick, he moves quick. Everything else is very slow compared to him, it’s like he’s always at the ATM waiting for the bastard in front of him to finish."

Josh Helman as Major William Stryker; a soldier who hates mutants. Helman was originally chosen to play a younger version of Juggernaut before that character was removed from the script. Brian Cox, who portrayed Stryker in X2, appears in archive footage.

Daniel Cudmore as Peter Rasputin / Colossus; a mutant who can transform his body into organic steel, which grants him superhuman strength, stamina, and durability. Cudmore was asked whether he trained for his role; he replied, "I didn't have a ton of time to get film ready for this. A trainer friend of mine from Vancouver put together a quick little workout program for me. Since the role was for Colossus, I was aiming to bulk up a bit and get stronger. I ended up eating a lot more. Because of how much I was eating, I had to eat every 2-3 hours to keep my calories up."

Fan Bingbing as Clarice Ferguson / Blink; a mutant who can create portals to teleport. Fan said the film was the first of a five X-Men movie contract she signed with 20th Century Fox.

Adan Canto as Sunspot; a mutant with solar-powered super-strength, near invulnerability, and the ability to create flames. To prepare for the role, Canto researched Sunspot because when he was cast, he did not know the level of involvement his character has in the film.

Booboo Stewart as James Proudstar / Warpath; a mutant with super-strength, super agility, near invulnerability, and superhuman senses. In preparation for the role, Stewart gained 50 pounds and grew his hair much longer than its usual length.
