Fan Casting Yelena Belova in Marvel Studios' Avengers: Doomsday

Yelena Belova, Natasha Romanoff’s sister, was a Red Room Black Widow under Dreykov. Freed, she helped destroy the Red Room, killing Dreykov. Revived post-Snap in 2023, she learned Natasha died. Misled by Valentina Allegra de Fontaine, Belova targeted Clint Barton but spared him and Kate Bishop after learning Natasha’s sacrifice. Betrayed, Belova formed the Thunderbolts with U.S. Agent, Ghost, and Red Guardian to save Manhattan from Bob Reynolds, the Sentry, whose Void alter ego threatened chaos. After saving Bob, they were redubbed the New Avengers. Fourteen months later, they saw the Fantastic Four’s spaceship enter Earth’s orbit.
