- "Powers? What powers? What're you talking about? You see something strange here? Not anything anyone would believe if you told them."
- ―Peter Maximoff[src]
Peter Maximoff, also known as Quicksilver, is a mutant capable of moving and thinking at superhuman speeds. Following the defeat of En Sabah Nur in 1983, he joined the X-Men under the tutelage of Beast and Mystique.
Quicksilver caused World Record scandal after breaking eight records in Track and Field, causing athletic officials to ban mutants from competing in professional sports.
At some point, he was captured by William Stryker for experimental purposes and was locked up in his mutant testing facility on Three Mile Island. He is tied down via bungee cords to prevent him from building up enough kinetic energy to escape.
As Logan comes and frees all of the incarcerated mutants, he and the others escape with the help of Professor X and his helicopter.
Logan, Hank, and Xavier traveled to the residence of the teenager, where they find Peter in his basement playing arcade games, noticing the massive amount of stolen items he had amassed. After convincing Maximoff to assist them in breaking Magneto out from the Pentagon, the group traveled to Washington.
Hank acted as a tourist, while Peter, Charles, and Logan travelled to the lower floors. Peter managed to duct tape a security guard to an elevator wall, stealing his uniform. After making it through security, Peter accessed Magneto's cell, where he used vibrations from his hands to shatter the glass ceiling of the cell. As both mutants took the elevator to regroup with Logan and Charles in the building's kitchen, they were quickly cornered by guards, who shot at them.
Quicksilver seized the opportunity to have some fun, darting around the room, disabling and mispositioning the guards and rearranging the fired bullets so that they avoided the other three. After the group escaped the Pentagon, Quicksilver was sent off by Charles, thanked for his contributions by letting him borrow his car, as long as he doesn't go too fast.
Later, Peter watched the news with his younger sister as they broadcast Magneto's speech.
Ten years have passed since Peter helped break Magneto out of The Pentagon, later learning that he is his father. Peter is sitting in his basement watching the news about Magneto reappearing in Poland, when he changes the channel and begins to play Ms. PacMan when his mom comes down to check on him. Peter reassures her that he's fine until she puts the news back on, telling him that she knows that he's going to go after his father and that she can't stop him, but warns that it won't end well. Peter says he's not afraid of him, but his mother says that he should be. Once his mom leaves, Peter looks at the car he took from Xavier ten years back.
He later arrives to the school eating a twinkie and notices an explosion coming from inside the school, caused by Havok's blast. Peter rushes into the school and makes his way down to the basement where he sees the explosion and the X-Men. Able to save both the X-Men and the entire student body from the collapsing mansion, he learns from Hank that Xavier was taken. Scott looks for Havok, his brother's body, among the rubble after asking Peter where he was. He is saddened when he discovers that his brother has died.
William Stryker and his men arrive at the ruins of the school but before Peter can do anything, he is distracted by Raven's warning. He is then knocked out by a blast along with everyone else.
Peter, along with Hank, Raven and Moira are captured and taken to Stryker's Weapon X facility where they are placed in a cell. Peter wakes up to see Hank in his Beast form and freaks out, asking if that's going to happen to all of them. Beast just tells him that he forgot his meds at home.
After being questioned by Stryker, Peter asks Raven about Magneto and then reveals to her that he's his father. Raven is shocked and Peter tells her that Erik left his mom before he was born and when he found out the truth it was too late. After the group get a message from Professor X, they hear screaming and gun shots coming from the base. Kurt appears outside of the cell and tells the group to move away from the wall. Cyclops breaks the group out of the cell with his optic beams, Peter and the others follow Scott, Jean and Kurt as they lead them to Stryker's War Jet. Jean had freed Weapon X, Stryker's experiment, who had killed all of Stryker's soldiers. She helped to restore some of his memories and he then ran off into the wilderness outside the base. Scott then finds tactical flight suits, which the team put on. Moira pilots the jet to Egypt, where Xavier is being held captive.
The Four Horsemen of Apocalypse: Magneto, Storm, Psylocke, and Angel are there. En Sabah Nur planned on transferring his consciousness into Xavier's body in order to use his telepathy to recruit an army of mutants. He was rescued during the process but lost his hair as it was nearing completion. Kurt teleported him into the jet. Peter used his speed to slow down time and land punches and kicks on En Sabah Nur, but was eventually countered, and had his leg broken and arm dislocated. Before Peter would be killed, Raven saved him by impersonating Psylocke, attacking En Sabah Nur.
Angel was defeated and incapacitated in battle while Storm and Magneto had turned on En Sabah Nur. Scott also helped to keep En Sabah Nur occupied while fighting his physical form alongside Storm and Magneto, as Xavier telepathically fought En Sabah Nur in the astral plane. En Sabah Nur was finally defeated when Jean unleashed her true power, incinerating him.
After this, Xavier's mansion is rebuilt with the help of Magneto. Xavier also rekindles his relationship with Moira, having restored her memories. Peter, along with Scott, Jean, Kurt, and Storm, are trained as the new X-Men by Raven and Beast.

Powers and Abilities
- Superhuman Speed: Quicksilver can move faster than the naked eye can track and possibly many times faster than the speed of sound. His abilities allow him to move, think, act and perceive less than seconds, faster than the natural speed of time, making the world around him appear frozen in time or in slow motion when he uses his abilities.
- Extreme Force Generation: Due to his speed, Quicksilver can generate very high amounts of force, making the weight and hardness of other objects and people irrelevant while he moves at super speed. When he moves at super speed, Peter sees the world around him in slow motion and generates no resisting force, making him immune to kinetic energy, inertia, friction, pressure, and vectors. A simple tap on the cheek at super human speed was enough to send a fully grown man, flying. Also, while in super speed, pulling off curtains from large windows caused the windows and the surrounding wall to explode. He was even able to send Apocalypse flying through the air at great speed by hitting him at super speed, and repeated this process, allowing him to hit Apocalypse again and again mostly quicker than Apocalypse could react.
- Accelerated Perception: Due to his high speed, Quicksilver can perceive the world in slow motion which enhances his reflexes and thinking time.
- Infinitismal Horizontal Force: Quicksilver can run so fast that he is able to defy gravity and run up vertical surfaces.
- Advanced Hand-To-Hand Combatant: Quicksilver is very skilled in hand-to-hand combat; his fighting skills combined with his powers, makes Quicksilver a formidable opponent alone in single combat.
