Pietro Maximoff was born in 1989 to Oleg and Iryna Maximoff in Sokovia along with his twin sister, Wanda. Unknown to any of them, Maximoff was born with the latent power of super speed, making him the legendary Quicksilver. His ability was too weak, however, and was doomed only to diminish over time. Years later, both Pietro and Wanda volunteered to undergo genetic experimentation overseen by HYDRA's Baron Wolfgang von Strucker, using Loki's scepter, to potentially give them powers. One of the few survivors of the experiments, along with his sister, Pietro found himself with a lot of power. Pietro and Wanda joined the Avengers during the Battle of Sokovia to stop Ultron; Pietro was killed during the battle but Wanda survived, and shortly after relocated to the Avengers Compound in the United States of America.
