The Maximoff twins are featured correctly during “Avengers: Age Of Ultron,” following an appearance during the credits scene in “Captain America: The Winter Soldier” in 2014. Wanda and Pietro (Aaron Taylor-Johnson) are initially presented as the weapons of Hydra. When the Avengers storm the last Hydra complex in Sokovia, the twins end up working with Ultron (James Spader), who promises to help them end the superhero squad.
Pietro explains part of their origin story at Ultron’s request: The twins were 10 years old, having dinner with their family, when a bomb blew up their house and killed their parents. A second bomb – a bomb from Stark Industries – fell, but did not explode. Wanda and Pietro were trapped for two days, waiting “for Tony Stark to kill [them]. “” WandaVision “gives fans a glimpse of this moment as Wanda and Agatha Harkness explore Wanda’s origins. Wanda, unaware of her magic, used a probability spell to stop the shell detonation. Years later , the Maximoffs volunteered for experiments on Hydra and were exposed to the Mind Stone, gaining their distinct superpowers.
The dark stories of the Maximoffs do not end there. Pietro is killed by Ultron in “Age Of Ultron”. Grief-stricken Wanda who lost her parents, brother, and country, joins the Avengers and falls in love with Vision (Paul Bettany). Then Thanos sends his followers to retrieve the Mind Stone from Vision’s head. Despite all efforts to save him, Wanda is forced to destroy Vision and the Mind Stone to keep her away from Thanos – only for Thanos to go back in time and claim the Stone, killing Vision again. Ouch.
