Quicksilver

> You didn't see that coming?
>
> Quicksilver to Hawkeye, Avengers: Age of Ultron

**Pietro Maximoff** was a native of Sokovia who grew up with his fraternal twin sister, Wanda. The country, which was embroiled in constant war and strife, became the base of operations for a HYDRA cell operated by Wolfgang von Strucker, who recruited Pietro and Wanda to take part in a series of tests involving the Scepter, giving the twins superpowers. While his sister received a number of mental abilities, Pietro acquired the ability to move at supersonic speeds and other physical features.

When HYDRA fell, the twins joined Ultron to continue their quest for revenge on Tony Stark over his weapons killing their family, but eventually Anaztazya Oztrovzky, a member of the Avengers, persuaded them to switch sides and helped the Avengers when they discovered Ultron's true intentions. Pietro then fought in the Battle of Sokovia alongside all of the other Avengers, but later sacrificed his own life to protect Hawkeye and Costel, much to his sister's grief. He was brought back to life by Oztrovzky with her abilities and the Mind Stone. The two shared a vital connection and Pietro helped piece together Oztrovzky's past. Pietro fought on Iron Man's side in the Avengers Civil War, against his sister. After the fight, he and Oztrovzky left the Avengers in order to be left alone by the government. They were called back in action in 2018, to protect Vision from the Mad Titan, Thanos in his quest to pursue the six Infinity Stones. He was among those who died when Thanos succeeded and snapped his fingers, killing half of the population of the universe.

He was brought back again in 2023 by the Hulk and participated in the Battle of Earth. After the battle he was reunited with his sister and Oztrovzky. He attended the funeral of Tony Stark.

## Biography

### Early Life

#### Losing their Parents

> We were ten years old, having dinner, the four of us. When the first shell hits, two floors below, it makes a hole in the floor. It's big. Our parents go in, and the whole building starts coming apart. I grab her, roll under the bed, and the second shell hits. But, it doesn't go off. It just...sits there in the rubble, three feet from our faces. And on the side of the shell is painted one word..."
> "Stark.
>
> Pietro Maximoff and Wanda Maximoff, Avengers: Age of Ultron

Pietro Maximoff was born in Sokovia along with his twin sister, Wanda. At the age of 10, while having dinner with his family, a mortar shell hit their apartment building, killing Pietro's parents while trapping him and his sister. Pietro led Wanda under their bed to take shelter from the collapsing building. A second shell then hit the structure and landed three feet in front of them but did not go off; the Maximoff twins were left trapped under the rubble for two days, terrified for their lives, as they waited to be rescued while staring at the unexploded shell, which bore the name Stark Industries.

#### Protesting Against Heroes

> We're not at war, Captain."
> "They are.
>
> Maria Hill and Captain America, Avengers: Age of Ultron

This horrifically traumatic experience gave the twins a great hatred for Tony Stark, and later the Avengers. At the same time, Pietro became highly protective of his sister. Driven by this hatred growing up, they often took part in and would lead protests against the Avengers, searching for ways to bring the group down. This constant political activity put Pietro and Wanda on S.H.I.E.L.D.'s radar as a potential threat to world security, as well as HYDRA's.

### Avengers Conflict

#### Recruited by Baron Strucker

> Be strong, sister. It won't be long before we have the power we need to fight.
>
> Pietro Maximoff to Wanda Maximoff, Avengers: Age of Ultron Prelude - This Scepter'd Isle

By the time the twins reached adulthood, the United States of America had begun occupying Sokovia, pushing the country into a state of turmoil. Pietro and Wanda took part in frequent riots to drive American forces out of their streets. What the twins did not know was that the riots were orchestrated by HYDRA, who had taken up residence in the country and were using its conflict as a cover for their illegal experiments. Wolfgang von Strucker was attempting to harness the energy from the Scepter for a variety of uses, such as powering up weapons of mass destruction.

List, desiring to see what effect the Scepter's power would have on live humans, approached several Sokovian rioters, including the Maximoff twins, and offered them the opportunity to achieve the power needed to free their country from war. While Wanda expressed some doubt over Strucker's claims, Pietro was determined to save Sokovia and convinced his sister to accept. Upon exposure to the Scepter, the other volunteers did not survive but Pietro and Wanda experienced drastic changes, with unlocked latent supernatural powers within them; Pietro was now able to move at superhuman speeds, with enhanced durability and perception, while Wanda developed a number of mental powers.

#### Attack on the Research Base

> Let's show them what we have accomplished. Send out the twins.
>
> List to Wolfgang von Strucker, Avengers: Age of Ultron

Soon after the Maximoffs' abilities had been unlocked, the Avengers arrived in Sokovia and raided the HYDRA Research Base, attempting to defeat HYDRA and take the Scepter. As the alarms sounded, List recommended to Wolfgang von Strucker that they send the twins to fight the Avengers, but Strucker refused. In the confusion, Pietro and Wanda escaped from their holding cells, and though inexperienced, were able to use their powers to evade the guards and escape to defend the base.

While Wanda was defending Strucker inside the base, Pietro found Hawkeye outside attempting to use an explosive arrow to destroy a HYDRA bunker. Maximoff used his powers to run in front of the arrow and caught it in mid-air before knocking Hawkeye off his feet and mocking him. In the confusion, Hawkeye was shot and nearly killed by a cannon, but the Hulk defended him and destroyed the bunker. Pietro then attacked Captain America, using his speed to try to stop the Avengers' advance and to protect the base.

Returning to the inside of the base, Pietro found his sister hexing Tony Stark and forcing him to see a future involving the death of all the Avengers. Pietro recommended that they kill him, as they had intended to do for years, but Wanda refused, allowing Stark to steal the Scepter as she had had a vision of what he would do with it. Although Pietro disagreed with this decision, he did not argue with his sister. The Avengers won the fight and HYDRA was seemingly defeated, forcing the twins to escape the base before going on the run.

#### Joining Ultron

> You need patience. Need to see the bigger picture."
> "I don't see the big picture, I have a little picture. I take it out and look at it, every day.
>
> Ultron and Pietro Maximoff, Avengers: Age of Ultron

With the HYDRA Research Base and Wolfgang von Strucker captured, the Maximoffs returned to Novi Grad and Pietro provided for them by stealing items for himself, Wanda, and the local people. Pietro handed out the items, including a football for Costel and a dress for Zrinka. Wanda mocked Pietro's attempts to flirt with the women and warned him he would get shot if he kept stealing. As Pietro began to question Wanda's decision to let Tony Stark go free, Costel approached the pair and told them that "Iron Man" was waiting in a nearby church for them.

Pietro and Wanda went to the church and found a "man" waiting for them wearing a red cloak who spoke about how much he enjoyed the church. When Wanda questioned why she could not read his mind, the "man" revealed himself to be Ultron. Ultron explained that he intended to destroy the Avengers and wanted the Maximoffs to help him complete his plans. Ultron then led them from the church and back to the HYDRA Research Base.

Ultron revealed that he had taken over the base and was using HYDRA technologies to create an army of Ultron Sentries; knowing that with their powers, they could tear the opposition apart. When they discussed the reasons for killing the Avengers, Pietro told Ultron the story of how they had lost their parents due to a Stark Industries' missile. Although they were initially unsure, Ultron assured them that they would use their powers to kill the Avengers; noting that while he and Pietro could defeat them with strength, Wanda would be able to tear them apart from the inside.

#### Battle at the Salvage Yard

> Ah, this is funny, Mr. Stark. It's what, comfortable? Like old times?"
> "This was never my life.
>
> Pietro Maximoff and Iron Man, Avengers: Age of Ultron

Pietro and Wanda accompanied Ultron in acquiring Ulysses Klaue's supply of Vibranium. The Maximoffs entered the Salvage Yard first and shut off the lights before Pietro disarmed Klaue and confronted him. Klaue remained unimpressed by the Maximoffs, having heard of them already. He noted that he was saddened to hear of Wolfgang von Strucker's death, then mocked the pair for their reaction to the news.

Eventually, Klaue told the pair that he would have no respect for them if Wanda used her powers to make him see what he feared, a cuttlefish, and he wished to speak to the man in charge. In response, Ultron threw Klaue through a window and introduced himself. Ultron then forced Klaue to sell him his stockpile of Vibranium in exchange for billions of dollars. When Klaue noted that Ultron was quoting Tony Stark, the comparison threw Ultron into a rage, resulting in him slicing off Klaus's left arm and kicking him down a flight of stairs.

When the Avengers arrived, Captain America attempted to convince the Maximoffs to walk away while they still had a chance, but they both refused. Iron Man attempted to learn what Ultron's plan was, but this resulted in a fight breaking out. Pietro attacked Captain America and Thor, using his incredible speed to dodge their attacks. At one stage, Pietro tried to use Mjølnir against the team, but was unsuccessful and thrown across the room and knocked back by Captain America. He soon recovered and injured Captain America by throwing him across the room, leaving him vulnerable to his sister's attacks.

When Wanda attempted to hex Hawkeye, he subdued her with a taser arrow to the head. Pietro saved her in the nick of time and threw Hawkeye through a window. He took her outside Klaue's base and tried to go back inside to kill Hawkeye, but she insisted that she was all right and wished to continue with the plan. She caught sight of Bruce Banner and hexed him as well, causing him to transform into the Hulk and go on a rampage in Johannesburg. The twins used the distraction to their advantage and escaped in the chaos.

#### Ultron's True Intentions

> We have to evolve. There's no room for the weak."
> "And who decides who's weak?"
> "Life. Life always decides.
>
> Ultron and Pietro Maximoff, Avengers: Age of Ultron

When the trio arrived in Seoul, Ultron used the Scepter to indoctrinate Helen Cho, forcing her to use the vibranium in synchrony with the Regeneration Cradle to build a new, more powerful body for Ultron. As Ultron's consciousness was being uploaded into the body, Wanda curiously took the opportunity to explore Ultron's mind and was horrified to learn of Ultron's true plans, which involved the genocide of humanity in its entirety. With Pietro, Wanda abandoned Ultron and left the facility, much to the automaton's rage.

#### Battle of Seoul

> I'm fine. I just need to take a minute."
> "I'm very tempted not to give you one.
>
> Quicksilver and Captain America, Avengers: Age of Ultron

The twins attempted to escape Seoul, but as they made their way through the city, they spotted a news report showing that the Avengers were attempting to steal the Regeneration Cradle, and battling Ultron and his army in the middle of the city, endangering thousands of lives. Refusing to allow the people of Seoul to be put in danger, the Maximoffs decided to assist the Avengers in the fight.

The twins found and assisted Captain America in fighting off Ultron on a moving passenger train. Pietro charged onto the train and knocked Ultron back while Wanda trapped him inside by twisting the metal to put a defensive barrier between Ultron and the Captain. However, Ultron responded by firing a blast into the front of the train, killing the driver, and destroying the controls of the train before escaping, leaving the train charging straight forwards the center of the city of Seoul and forwards the people standing in its path.

With the train now completely out of control and heading to the middle of the city, Rogers ordered Pietro to use his incredible speed to move the civilians out of its path while Wanda stopped it. Pietro ran as fast as he physically could and pushed everyone he came across out of the path of the train. Despite the train still traveling at its full speed and Pietro using every ounce of energy he had to keep moving at such a speed, he still managed to stay ahead and saved dozens of lives before Wanda was finally able to stop the train in the center of the city.

With the train now stopped, Pietro took a break to rest as he could barely stand after running so fast for so long. When Rogers revealed that the Regeneration Cradle and Ultron's would-be body had been sent to Tony Stark for analysis, Wanda was disturbed, aware that Stark would attempt to utilize the body rather than destroy it in order to correct his own folly. Although the Captain was reluctant to accept this as a possibility, Wanda compared Stark and Ultron and made key comparisons with their mindsets.

### Changing Sides

#### Birth of the Vision

> No, no. Go on. You were saying?
>
> Pietro Maximoff to Tony Stark, Avengers: Age of Ultron

The Maximoffs were taken to Avengers Tower in New York City by Steve Rogers. Once there, they discovered that Tony Stark was attempting to program Ultron's being in the Regeneration Cradle with J.A.R.V.I.S.. Rogers ordered Stark to terminate the program as it was too dangerous, Stark refused, so Maximoff used his incredible speed to unplug and damage the machine. As he took a moment, he noticed a bullet coming up from the ground below him. Before he could react, the glass he was standing on shattered and he was captured by Clint Barton, who mocked him using the same phrase Maximoff taunted him with earlier.

Rogers' and Stark's argument hit a boiling point and the pair began fighting until Thor arrived and used his lightning to power the Regeneration Cradle, causing the being inside to be born. The being briefly attacked the Avengers before overlooking the city and calming down. The being apologized and explained that he was not Ultron or J.A.R.V.I.S., but a new Vision. He told them that they needed to go to stop Ultron. He ultimately gained their trust when he handed Thor Mjølnir. Maximoff and the rest of the Avengers could only look on in shock and confusion.

Pietro and Wanda then agreed to help the Avengers to stop Ultron and save Sokovia, where he would be enacting his final plan. Pietro took a new uniform and threw a red jacket at Wanda for her to wear, and joined the Avengers on the Quinjet as Rogers gave a speech where he informed the team that their priority was getting the people of Sokovia out of harms way before Ultron could destroy their homes and their lives. Pietro stayed silent, still unsure of trusting the Avengers in the long term. However, he shared their intention to save the lives of his friends.

#### Battle of Sokovia

> We're under attack! Clear the city, now! Get off your asses.
>
> Quicksilver, Avengers: Age of Ultron

Pietro and his sister joined the Avengers in evacuating the citizens out of Sokovia before the upcoming battle. While the rest of the team quietly moved the people out, Maximoff's method of evacuating them is more aggressive, charging into a police station and ordered Sokovian Police Department to clear Novi Grad. When none of the police officers in the station listened to him, Maximoff returned and fired a machine gun into the air, demanding they hurry up.

Quicksilver went into different houses and told the people who were still there to leave the city and bring nothing with them. He then went to a young woman and told her to evacuate. Quicksilver then went back to her and asked that he might see her later, and then went to help other civilians.

Seeing what the Avengers were trying to do, Ultron unleashed his army of Ultron Sentries upon the civilians. Pietro readied himself and charged into the robots, the speed of which he impacted them ripped them apart in a millisecond. When the city started to rise due to the device Ultron had planted inside it, Maximoff, alongside the Avengers, watched in horror while Ultron explained his grand plan to turn the city into a giant meteor and destroy all human life on the planet so only he and his metal army remained to rule the Earth.

Using his speed, Quicksilver took out numerous robots as he charged across the city tearing them apart and keeping the people still in the city safe. While Iron Man flew around the city and worked out a plan to stop Ultron's scheme, Captain America gave a speech to the team in which he ordered them to do whatever they could to destroy the Sentries, telling them not to even let death stop them. Quicksilver took a moment to catch his breath before continuing to fight.

Before long, Quicksilver came across Scarlet Witch and Hawkeye who were working together in their own battle against the Ultron Sentries. As they walked to their next mission, Quicksilver charged in and picked up his sister before running away with her in his arms and teasing Barton, calling him an old man and telling him to keep up. Barton considered shooting Quicksilver in the back for being such an annoying teammate and continued to jog far behind them. When Black Widow regrouped with the Avengers, Rogers told her that they fight robots today. Quicksilver rushed by and joked that next month might be better for them, and then rushed off again.

Quicksilver carried Scarlet Witch into the center of a fight between the local police and some Sentries. They worked together to tear the machines apart while the police chief ordered his men not to fire upon the Maximoffs. However, during the battle, he was accidentally shot in the arm by one of the officers. The wound was minor and non-life threatening, but Maximoff still turned to the officer who had fired and glared at him for ripping his uniform.

#### Reinforcements

> This is S.H.I.E.L.D.?"
> "This is what S.H.I.E.L.D.'s supposed to be."
> "This is not so bad.
>
> Quicksilver and Captain America, Avengers: Age of Ultron

As the battle became more and more intense, Captain America became focused on finding a way to save the remaining citizens. In response, Nick Fury and Maria Hill arrived on a Helicarrier and used evacuation pods to get the people to safety. Maximoff watched this unfold and turned to Rogers, asking if this the S.H.I.E.L.D., Rogers told him that this is what S.H.I.E.L.D. is supposed to be, which Maximoff happily accepted.

#### Protecting the Key

> Get the people on the boats."
> "I'm not going to leave you here."
> "I can handle these.
>
> Scarlet Witch and Quicksilver, Avengers: Age of Ultron

The team regrouped around the church in the center of the city, where Ultron had placed his device's key, which if activated would drop Novi Grad upon the Earth and cause a devastating explosion. Ultron flew outside the church where Thor challenged him to a rematch, so Ultron responded by showing off his entire remaining army of Ultron Sentries vastly outnumbering the Avengers. The team remained together as they prepared for the final showdown.

Ultron unleashed his sentries upon the Avengers all at once in his attempt to activate the key. Quicksilver and the Avengers fought them off with every bit of strength they had. Quicksilver darted around the arena, ripping the Sentries apart as quickly as he could. Before long, Ultron himself attempted to attack Vision, but with the help of Iron Man, Thor and the Hulk, Ultron was overpowered. A heavily injured Ultron was thrown across the city.

The team decided it was time for them to escape and Captain America ordered them to sweep the city for any remaining drones before getting on the escape pods. Scarlet Witch decided to stay behind and protect the key from Ultron. Quicksilver was reluctant to leave his sister but she told him she could take care of herself and told him to get all the civilians on the evacuation ships and to come back for her. He then proceeded to tease her about her bossy attitude by reminding her that he was still the elder twin.

#### Self-Sacrifice

> You didn't see that coming?
>
> Quicksilver to Hawkeye, Avengers: Age of Ultron

During the battle, Ultron hijacked the Avengers' Quinjet and began to fire its guns at civilians. When Quicksilver saw Ultron targeting Hawkeye and Costel using a minigun-barrage, he ran to aid them without a second thought.

Running into the path of the bullets, Quicksilver used his own body to shield them from the gunfire, saving both Barton and Costel. After the dust settled, the bullet-ridden Maximoff then took one last glance at Barton, remarking if he saw that coming before collapsing and dying from his wounds, much to his sister's sorrow. His body was taken onto an escape pod by Barton.

There, Anaztazya Oztrovzky, latched herself onto his body. By using her abilities, now merged with the Mind Stone, she was able to revive Pietro within minutes of his death.

## Personality

> Keep up, old man!
>
> Quicksilver to Hawkeye, Avengers: Age of Ultron

Pietro is a rather cocky, arrogant, impatient, tenacious, and quick-tempered person. These personality traits are likely a side effect of his super-speed, due to thinking and acting at a much faster rate than most. Despite this, Pietro has a desire for peace as he wished to save his country to the point he was willing to be experimented on by HYDRA, giving him the formidable powers he now possesses.

He also deeply cares for Wanda and the two shared a deep bond though they would occasionally bicker like normal siblings. He looked after his sister and relied on her for support, while also being fiercely loyal and protective of her that he was willing to kill Hawkeye when he incapacitated Wanda with a shock arrow. Wanda was devastated by Pietro's death at the hands of Ultron, to the point she said to Ultron that she just 'died'.

Pietro originally desired to destroy the Avengers and in particular, Tony Stark for revenge, to the point they decided to join Ultron when he said he shared the same goal. However, Pietro chose to betray the A.I. when he found out about his true goal, showing that he is willing to put aside his personal grudges for the greater good.

Out of his relationships with the Avengers, his most complicated was with Hawkeye. Ever since they first met, the two had constantly competed, fought, and taunted each other. Though this initially started out as hatred, their relationship eventually becomes a friendly rivalry and they became good friends and teammates through Pietro helping the Avengers, while still continuing their friendly banter during the Battle of Sokovia. He later proves himself a true hero and Avenger by sacrificing his life to protect Hawkeye and Costel from the Quinjet's gunfire. Hawkeye later named his newborn son, Nathaniel Pietro Barton, showing that he deeply respected Pietro for his choices.

## Powers and Abilities

### Powers

> He's got increased metabolism and improved thermal homeostasis.
>
> Maria Hill to Captain America, Avengers: Age of Ultron

* **Superhuman Speed**: Quicksilver gained the ability to run at extremely high speeds due to HYDRA's experiments with the Scepter. He was able to think, act, move, and perceive in seconds or less, far faster than normal people could even perceive. As such, he could perceive the world as moving in slow motion, especially when he is moving at super speed, while all others could see of him as he used his speed was a vibrating blur of motion. His power caused him to generate an aura of blue, white, and transparent energy currents and mist-like shapes, much like fire or wind, leaving behind a trail of it as he runs. When imprisoned by Wolfgang von Strucker, he was able to move from one end of his cell to another in less than a fraction of a second. His abilities made him nigh unbeatable in battle, with his speed giving him the ability to generate extreme force and momentum, as he could hit harder than normal humans while moving at super speed. In his confrontation with the Avengers, he managed to avoid multiple attacks and took down Captain America in seconds. This ability made him able to outmaneuver someone as fast and perceptive as Hawkeye with absolute ease, catching his arrows and sending him flying through the air multiple times. It was only his ignorance towards Mjølnir that allowed Quicksilver to be caught off guard, knocking him down for a while. Shortly afterward, however, he took down Captain America again. He used his speed to quickly save Scarlet Witch from Hawkeye after knocking him down as well. His maximum speed was Mach 4.
	+ **Extreme Force Generation**:

Quicksilver had enhanced momentum, which allowed him to enhance the force in his attacks, strikes, impacts, and collisions, often propelling objects or people several feet, that he used to compensate for his average human strength. He was, therefore, able to match Captain America's far superior strength in their confrontation, allowing Quicksilver to send the latter flying by colliding into him and knocking him to the floor with one punch while moving at super-speed. During the Battle of Sokovia, Quicksilver used this ability again to dismantle numerous Ultron Sentries by colliding with them at great speeds. This force, however, was not enough to injure Thor, who was barely affected by Quicksilver smashing into him at supersonic speeds. Quicksilver's aura seems to protect those he carries even though they lack his enhanced physiology. Quicksilver can move multiple people in an instant, without risking whiplash injury or damage caused by high-speed air friction.

* + **Increased Metabolism**: Quicksilver has a hyper-accelerated metabolic rate, enhancing his physicality and ability to move and act while also making him less able to be stunned by attacks or injuries, as he quickly recovered from the pain of being shot in the arm and could still act as if he were not injured.
	+ **Improved Thermal Homeostasis**: Quicksilver can function in a stable internal environment that requires constant monitoring and adjustments to his condition that changes constantly, meaning he can resist the effects of friction and temperature while moving at incredible speeds.
	+ **Accelerated Perception**: Quicksilver's increased speed also augmented his reaction time, allowing him to react to danger and events much faster than a normal human, to the point where he could catch bullets in mid-air. As a result, Quicksilver tended to see the world around him as if it were in slow motion, especially when he is moving at super speed. However, even with his enhanced reflexes, Quicksilver can still be caught by surprise, such as his fight against Hawkeye during the confrontation between Iron Man and Captain America at Avengers Tower.

### Abilities

* **Combatant**: Maximoff was adept at using his powers in combat, defeating several Ultron Sentries, landing an efficient punch against Captain America and bumping into Ultron.
* **Bilingualism**: Maximoff speaks his native Sokovian, as well as fluent English, albeit with a heavy Sokovian accent.

## Equipment

### Weapons

* **RPK**: Maximoff rushed into the Sokovian police station and demanded they clear Novi Grad for the incoming threat of Ultron. They ignored him and Maximoff returned with an RPK light machine gun. Maximoff frightened them into action by firing the RPK light machine gun into the roof of their police station.

### Other Equipment

* **Uniform**: In preparation for the Battle of Sokovia, Pietro picked out a uniform he found in Avengers Tower and wore it into battle.

## Facilities

* **HYDRA Research Base**: During the experiments with the Scepter, Maximoff was living in a HYDRA base. Being specifically as a test subject, Maximoff was held in a room where he trained his powers.
* **Avengers Tower**: After joining the Avengers, Maximoff was living in the tower for a short amount of time.
* **Paris Apartment**: This was the apartment Maximoff shared with Anaztazya Oztrovzky when they were hiding in Europe together. They moved back into the apartment in 2023 after the Time Heist had succeeded.

## Trivia

* In the comics, Quicksilver is a mutant and a founding member of the Brotherhood of Mutants, being initially identified as the son of Magneto (Erik Lehnsherr) and his then-wife Magda Lehnsherr (née Eisenhardt) in *Vision and the Scarlet Witch* #4 (1983), 19 years after Scarlet Witch and Quicksilver's first appearance. Magda leaves Erik while pregnant and takes sanctuary at Mount Wundagore in Transia, the home of the High Evolutionary, where she gives birth and later dies. The High Evolutionary then places them instead in the care of the Romani couple, Django and Marya Maximoff, who raise them as their own children. Prior to that, in *Giant-Size Avengers* #1 (1974), they were revealed to be the biological children of Golden Age superheroes The Whizzer and Miss America, a fact that was later retconned. In *Avengers & X-Men: AXIS* #7 (2014), it was revealed that Pietro and his sister have no blood ties to Magneto and are not related after all. In *Uncanny Avengers* #4 (2015), it is confirmed not only they are not related to Magneto but they are not even mutants, as the High Evolutionary genetically altered them as infants, giving them their powers, before returning them to their true parents, the Maximoffs.
* Pietro was twelve minutes older than his sister.
* Quicksilver is the first member of the Avengers to die in battle.
