Pietro Maximoff

"You didn't see that coming?"

- Pietro Maximoff

Pietro Maximoff is capable of moving and thinking at superhuman speeds. He is twin brother of Wanda Maximoff.

Avengers: Age of Ultron Prelude - This Scepter'd Isle
As HYDRA was harnessing the power of the scepter for a variety of effects, such as powering paraphernalia ranging from their own technology to Chitauri tech recovered from New York, Strucker approaches a group of Sokovian rioters, offering them the power needed to save their country. Among the rioters are twins Pietro and Wanda Maximoff. The Sokovians agree, and each undergo a number of tests where they are exposed to the scepter's energy; out of all of the test subjects, only the Maximoffs survive.

Captain America: The Winter Soldier
Wolfgang von Strucker led a HYDRA scientist to "the twins", and declared it was the "age of miracles". Quicksilver and Scarlet Witch were held in separate cells in the HYDRA base.

Avengers: Age of Ultron
Pietro and his sister Wanda were waiting with Baron Strucker when the Avengers raided the Sokovian HYDRA outpost. The Twins joined the fight and Pietro caught Hawkeye's arrows before they could hit their target and punched Captain America, knocking him down before rejoining his sister who decided to let the Avengers take Loki's Scepter after seeing inside Tony Stark's mind.

Ultron, knowing that the Twins hated Stark, met with them in a Sokovian monastery where Pietro explained how their family was killed by Tony Stark's bombs. Ultron offered them a position by his side and they accepted.

They went to South Africa to get Vibranium from Ulysses Klaue but were attacked once more by the Avengers. Pietro engaged Captain America and managed to land several blows before being knocked down. After finding Wanda injured from her fight with Hawkeye they both left with Ultron for Seoul.

In Seoul, Wanda read the mind of the currently-being-built Vision who was embedded with the Mind Gem and saw the cataclysmic future that Ultron desired. Pietro lifted his sister and escaped the laboratories. When the Avengers came to stop Ultron, Pietro and Wanda assisted them and once the Vision was retrieved they return with Captain America to Avengers Tower.

Pietro sided with Captain America when it was discovered that Stark had began to upload J.A.R.V.I.S. into the Vision, wishing to create another android. Pietro pulled out the power sources when Hawkeye shot the glass floor he was standing on. After the Vision explained his alliance, the group left for Sokovia where Ultron had returned to.

During the Battle for Sokovia, Pietro managed to help evacuate some of the civilians and destroy several dozen Ultron Sentries. When Ultron attempted to gun down the Avengers using the Quinjet Pietro saved Hawkeye and the injured child he was carrying. After he stopped running he realized that the bullets had actually hit him and fell down next to Hawkeye, his last words being "You didn't see that one coming."

In the aftermath of the battle, Hawkeye gave his newborn child the middle name Pietro in honor of his fallen ally.
