In comic lore, Alexi Shostakov was one of the Soviet Union’s most acclaimed test pilots. He was turned to The Red Guardian, an alias that was created as the Soviet equivalent of Captain America. If it wasn’t apparent enough, it’s now very clear the film will delve into Russia in Natasha’s origin as well as her adversaries.
