Quicksilver

"You didn't see that coming?"

- Quicksilver to Hawkeye

Pietro Maximoff, better known as Quicksilver, was a man who was born in the Eastern European country of Sokovia with his twin sister, Wanda. Sokovia, 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 Chitauri Scepter. The tests gave the twins superpowers; while his sister Wanda received a number of mental abilities; Pietro acquired the ability to move at supersonic speeds and other physical features.

Early Life
Pietro Maximoff was born in the Eastern European country of Sokovia along with his twin sister, Wanda. At the age of ten, they were made orphans when a mortar shell hit their apartment building.

Joining HYDRA
"Be strong, sister. It won't be long before we have the power we need to fight."

- Pietro Maximoff

When the twins reached adulthood, foreign powers began occupying Sokovia, driving the country into a state of turmoil. Pietro and Wanda took part in frequent riots to drive the foreign forces out of their streets. What the twins did not realize was that the riots were orchestrated by HYDRA, who had taken up residence in the country and were using the riots to cover up their illegal experiments. The leader of the HYDRA forces in Sokovia, Wolfgang von Strucker, was attempting to harness the energy from the Chitauri Scepter for a variety of uses, such as powering up weapons of mass destruction.

List, desiring to see the effect the scepter's power would have on live humans, asked approached several Sokovian rioters, including Wanda and Pietro, offering 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 free Sokovia and convinced his sister to accept.

While the other volunteers did not survive the scepter's power, Pietro and Wanda experienced drastic changes. The scepter unlocked latent supernatural powers within the pair; while Wanda developed a number of mental powers such as telekinesis, hypnosis, and energy projection, Pietro was now able to move at superhuman speed.

Self-Sacrifice
During the battle of Sokovia, Ultron hijacks a Quinjet and begins to fire its guns at civilians. Pietro bravely uses his powers to save countless lives and sacrifices his own to protect Hawkeye, and a civilian boy. He uses his own body to shield Hawkeye from the Quinjet's bullets, proving he was a true hero and a true Avenger
