Quicksilver's History
Quicksilver (born Peter Maximoff) is a mutant who has the ability of super speed.
When Wolverine travels back in time to 1973, he, Charles, and Hank go to Peter Maximoff's house to seek his help. The group meets Peter's mom, who tells them that she will write a check for whatever he took. Logan tells her that they just needed to talk to him and are welcomed into the house. Peter speeds around his basement while Logan tells him that they need his help breaking into a prison. Peter is at first uninterested until Charles informs him that he will be breaking into the Pentagon. This grabs Peter's attention, and when he asks the group on how he can trust them, Logan displays his claws - proving that they're mutants. Joining the X-Men on their mission, Maximoff easily infiltrates the Pentagon and enters an elevator with a guard who is bringing Magneto's food.
Maximoff duct tapes the guard onto the elevator's walls, steals his clothes, and poses as a guard while he makes his way to Erik Lehnsherr's cell. Once inside the cell, he places his hand on the glass ceiling and vibrates it to make it shatter, but in doing so sets off the alarm. Both Lehnsherr and Maximoff are able to escape using the latter's extreme speed. Lehnsherr and Maximoff soon rendezvous with the others at the kitchen.
After Charles and Erik have a rough encounter, the kitchen is suddenly filled with guards. Because of McCoy's serum, Charles is unable to effectively use his powers, so Erik begins to levitate all the metal in the room. This causes the guards to shoot at the group. However, Maximoff - using his extreme speed - begins to run around the room and stops the guards from killing the group by messing with their movements and redirecting the bullets fired at the others. The team then leave the Pentagon and head to Charles' private jet. Charles thanks Peter for his help and hands him the keys to their rental car, asking him to return it for them.
After his mission with the group at the Pentagon, Peter later returned home and proceeded to watch television in his living room, however he began to watch and listen to Erik as he delivers his speech about the presence of mutant kind, with his mother and sister. Peter eventually realized Magneto was his father, having been unable to process the facts on the short time he met him, Wolverine, Professor X, and Beast.
Quicksilver, still obsessed with finding his father, spends the next ten years looking for him. One day, he sees Magneto on the news, and eventually comes across his father's house in Poland. However, he is too late once more as the mutant had fled from the area and returns to his home to witness a special commemorating the 10-year anniversary of Magneto's attack on Washington D.C.
While watching the news, Peter's mother, Ms. Maximoff, goes down to the basement and calls out to him, causing the mutant to swiftly change the channel and play Pac-Man. Peter responds to her as she walks in and says she's just checking on him. He says he's good, just playing Pac-Man. Ms. Maximoff picks up the remote and changes the channel, asking if Peter's is sure he wasn't watching the news about Magneto, leaving Peter unresponsive. She then asks her son if he's going after Magneto, and Peter reminds her that she wanted him to get out of the house more. Ms. Maximoff says she can't stop Peter, nobody can, but tells her son that it's not going to end well, nothing does with Magneto. Peter states that he's not afraid of Magneto, and she says that he should be, before departing from the basement. Looking looking at the card he got from Charles Xavier, Peter then departs for the X-Mansion in search of answers.
Upon making it to the mansion, Quicksilver notices that it is exploding and uses his super speed to get everyone, starting with Beast, Mystique, and Moira MacTaggert, and even their pets out to safety on the school lawn. He initially does not fully take the situation seriously, even stopping to watch two people flirting and to get a drink, before realizing he should hurry and get everyone out just in time. Afterwards, Hank wonders where Peter came from, who explains that he was looking for the Professor, as he thought he lived there. When Scott Summers, Jean Grey, Nightcrawler, and Jubilee arrive at the scene, Scott frantically asks where his brother Alex is. Peter tells him that he's pretty sure that he got everyone out of the mansion, but Beast tells the speedster that Alex was closest to blast.
A chopper then descends to the ground. Moira approaches them, thinking they are part of another agency, until the leader, William Stryker, steps out and removes his sunglasses. Raven notices him and tries to warn everyone, but Stryker orders his men to fire a sonic blast that incapacitates everyone, except for Scott, Jean, and Nightcrawler. Stryker captures Moira, Beast, Quicksilver, and Mystique. Nightcrawler teleports himself, Scott, and Jean into their chopper, but he cannot get anyone out because of the electrical lining within.
Stryker takes everyone to his facility and traps Moira and the mutants in a room that keeps mutants from using their powers to escape. As the four wake up, Mystique shifts back to her human form, and Quicksilver notices that Hank has transformed into his Beast form, causing the young mutant to scream in terror and quickly rise to his feet. Moira and Mystique ask Quicksilver what's wrong as the latter wonders what's wrong with Hank, and questions if they are all gonna transform like he did. But Hank, realizing that he re-mutated, placates the speedster by informing him that he just left his medication at home.
After the four wake up, Mystique calls out to Stryker, who greets Mystique, who in turn addresses him as "Major Stryker", but he corrects her, saying it's "Colonel Stryker" now. He tells the four not to get too close to the walls, for it may create some discomfort. Moira introduces herself and points out that she is a senior officer of the CIA, but Stryker says he knows who she is. Moira says that he can't keep her imprisoned, but Stryker says he can. He explains the psychic event destroyed every nuke from Alkali Lake all the way to Moscow. That event emanated from where Stryker found the X-Men, at the home of the world's strongest psychic. Stryker then demands that the four prisoners tell him where Charles Xavier is. Moira tells Stryker that it's not Xavier he should be worried about, because there is someone else, someone more powerful out there. Mystique says that if he lets the four of them out, they can help. But Stryker refuses, asking Mystique if she really expects him to believe what she says. Stryker proceeds to tell Mystique that she can put on any disguise she wants, but he knows who and what she is. Stryker then walks off. Hank asks Moira about what she means by "someone more powerful than Charles".
Peter talks to Mystique about Magneto asking if she knew him. She used to, but is not so sure anymore. Peter asks what he was like, wondering if he is what people say he is, "the bad guy". Mystique says no, then yes, but it's too complicated to explain. She asks why Peter cares so much, asking if he saw Magneto's speech on T.V. or something. Peter confirms this, but, after a short, complicated pause, reveals that he Magneto is his father, greatly shocking Mystique.
Peter is about to explain that his mom and Magneto dated, but Mystique cuts him off saying she knows, fully aware of what happens next. She asks if the speedster is sure, and Peter says he is, as Magneto left Peter's mom before he was born. Peter explains that he met Magneto ten years back but didn't know it was him. By the time he figured it out it was too late. Earlier in the week, Peter saw Magneto on the news and went to his house looking for him, but by the time Peter got there, he was late again. Peter makes a note that, for a guy that moves as fast as him, he always seems to be too late. Mystique then tells Peter "let's hope not this time", which Peter complies to.
Charles Xavier, thanks to Apocalypse enhancing his telepathic powers, sends a message to everyone in the world, which is heard by all. After Charles broadcasted his message to the world, Stryker confronts his prisoners, noting that he recognizes that voice belonging to Charles Xavier, and once again asks them where the telepath is, wondering what's going on. But they don't know.
Soon after, the four prisoners watch in horror as Wolverine kills Stryker's henchmen. Nightcrawler enters the room above the cell Beast, Mystique, Quicksilver, and Moira are being held in and tells them to stay away from the door but they couldn't hear him. Nightcrawler used the loudspeaker so they can hear him, and repeats what he said, until they realize what the teleporter was saying and get away from the door. Nightcrawler counts to three but before he says "three", Scott blast down the door, and the septet make a way for the hangar where there is a plane they can use to escape. The group then don flight suits and board an warplane.
Aboard the aircraft, Jean and the others talk about how Mystique revealing herself to the public as a mutant was an influential moment to them. Peter also states that he may still live in his mom's basement, but everything is still the same, joking that he's a total loser, which makes everyone's laugh.
In Cairo, Mytsique spots Magneto, and upon hearing her say his father's name, Quicksilver dashes to the front of the plane to get a closer look. Mystique tells Scott and Jean to help Nightcrawler get into the pyramid in order to get Charles, while she takes care of Magneto. Beast wonders how they're gonna get through all the magnetic debris, and Quicksilver says he can get Mystique though it. Quicksilver came along for Magneto, telling Mystique to let him help her, to which they both nod in agreement. Mystique tells the others to get Charles on the plane, and get out of Cairo, but Nightcrawler objects, saying that they're not leaving without them, with the speedster telling the teleporter not to worry, they'll catch up. Beast and Moira then land the plane.
Upon landing, the team is divided up further, as Mystique tells Hank to go with the kids, while Moira guards the plane. Scott tells Mystique to wait, with her and Quicksilver turning towards the young mutant, who states not all of them can fully control their powers. She tells him "then don't", they all need to embrace their powers, as the shapeshifter reverts to her blue form. Quicksilver puts on his goggles, grabs Mystique and uses his speed to travel across a bridge of magnetic debris to Magneto, who is floating in the air and manipulating the Earth's natural magnetic forces, creating disasters across the globe.
Quicksilver fails to penetrate the magnetic field surrounding Magneto, for it's too strong, and thus can't get him and Mystique in there. Mystique calls out to Magneto, who responds by turning towards her and Quicksilver, and says Mystique's name. Mystique says she knows that Magneto thinks he's lost everything, but he hasn't. He has her, Charles, Mystique pauses as she and Quicksilver turn to each other, and she tells Magneto that he has more family than he knows. Magneto never had the chance to save his family before, but he does now. That's what she came to tell him. After remaining silent, Magneto asks Quicksilver "And you?", wondering if Quicksilver has anything to say. Peter is about to say that he�??s Magneto�??s - his son, but goes against it, believing that it wasn't an appropriate time, and instead says that he's there for his family too.
Quicksilver and Mystique see the plane taking off, and have looks of worry when the plane crashes, with Mystique saying Charles' name in worry. Mystique tells Magneto that she's gonna go fight for what she has left, and then asks "Are you?". Quicksilver then grabs Mystique, and spares a fleeting glance at his father before dashing off.
Using his amazing speed and strength to give Apocalypse a severe beating, Quicksilver gains the upper hand. Unfortunately, Apocalypse adapts to the speedster's powers by transmuting the ground to trap one of Quicksilver's legs, with Apocalypse calling Quicksilver a foolish child. Quicksilver throws a punch at Apocalypse, who catches it, twists the speedster's arm, and breaks his leg, causing Quicksilver to scream in pain, which is heard by Magneto, Professor X, and Mystique, the latter of which arrives on the scene disguised as Psylocke. Apocalypse sees her, grabs Quicksilver and orders "Psylocke" to kill Quicksilver, only for the shapeshifter to slash at Apocalypse's throat, only to get strangled in the process and blow her cover, as The First Mutant regenerates from his slash wound. However, the two are saved thanks to the interference of Professor X and Magneto.
Beast and Cyclops arrive, with Beast freeing Quicksilver's foot by breaking the ground that had the speedster trapped. While Cyclops joins Magneto to take down Apocalypse, Beast gets Quicksilver and Mystique to safety. Cyclops, Storm, Magneto, and an enhanced Jean Grey then manage to disintegrate Apocalypse. After Apocalypse is defeated, Magneto approaches Mystique and Quicksilver, removes his helmet, and tells them that it's finally over.
Following the reconstruction of the X-Mansion, Peter, who's on crutches, with his leg in a cast with a lot of signatures on it, is approached by Storm, who informs the speedster that Mystique told her that Magneto is his father, and asks if Peter is gonna tell him. Peter says he might, one day, when it's a good time. For right now, he's gonna stick around the X-Mansion for a while. Storm agrees, saying that she will stick with the X-Mansion too. Quicksilver's leg is soon all healed up. Later, upon receiving new costumes, Quicksilver, alongside Cyclops, Mystique, Storm, Jean Grey, Nightcrawler and Beast, gather in the Danger Room to train against some Sentinels under the watch of Mystique, Beast, and Professor X.
When Deadpool blew himself up after blaming himself for the death of Vanessa Carlysle, Colossus brought him to the X-Mansion to recover. While there, Deadpool began complaining that he never saw other X-Men around the mansion apart from Colossus and Negasonic Teenage Warhead. While ranting, Deadpool was unaware that Professor X, Cyclops, Storm, Nightcrawler, Beast, and Quicksilver were in a room behind him. Beast quietly closed the door so that he did not notice them.
