They are introduced as Hydra assets, both acquiring superhuman powers after volunteering to be experimented upon by the Mind Stone, with Pietro gaining superhuman speed.

In the final conflict with Ultron, Pietro dies a hero's death, saving the lives of Clint Barton and a Sokovian boy. In 2023, the witch Agatha Harkness forces Westview resident Ralph Bohner to impersonate Pietro to get close to Wanda within her created alternate reality.
