Yelena Belova (Russian: Елена Белова) is an adoptive sister of Natasha Romanoff and the Red Room operative who worked for General Dreykov. Following Romanoff's defection from the Red Room, Belova and other Black Widows were put through the mind controlling programming and turned into Dreykov's obedient subordinates. After being freed from the control, Belova joined forces with Romanoff, as well as their adoptive parents Alexei Shostakov and Melina Vostokoff, to bring down the Red Room once and for all. They eventually succeeded and liberated all Black Widows, as Belova killed Dreykov with her own hands. After parting her ways with Romanoff who later died under unknown circumstances, Belova was recruited by Valentina Allegra de Fontaine who informed her that Clint Barton was responsible for the death of her sister.
