Red Guardian is a fictional comic character created by Roy Thomas and John Buscema and published by Marvel Comics. First appearing in The Avengers #43 back in August 1967, Red Guardian was created as a Soviet equivalent of Captain America.
Before his apparent transformation to a super soldier from the Soviets, Red Guardian's alter ego, Alexei Shostakov, was a renowned soviet pilot that fought in numerous battles against the Nazis in WWII and a national hero in the magnitude of Yuri Gagarin. Alexei met Natalie Romanova aka Black Widow in his years of fame and they got married before he decided to become the Red Guardian.
The History of the Red Guardian
During the 50s Alexei was approached by Soviet Premier Nikita Kruschev and was asked to become a national icon by taking the mantle of the Red Guardian. After accepting the responsibility of becoming a weapon for his country Alexei had to fake his death to even his wife.
After intensive training from the KGB Alexei became the Red Guardian reaching the peak of human performance even without a serum.
As it was expected eventually Alexei as the Red Guardian came to a crash with the Avengers for trying to protect Chinese weapons from the Avengers where he came face to face with his wife Black Widow. After recognizing each other the Red Guardian refused to harm her and he was shot and killed by Colonel Ling, a Chinese Communist ally.
It was afterwards revealed that Alexei had survived the shooting and was operating under the name of Ronin in Bulgaria.
Just as with many characters of the Marvel Universe, Alexei Shostakov was not the first or last to use the name Red Guardian. There are actually numerous iterations of the name and Shostakov was the second to pick the mantle.
Aleksey Lebedev was the one to be called Red Guardian first in the Golden Ages and most notable Red Guardian is Josef Petkus, the fourth Red Guardian in line, the leader of Winter Guard who fought along site the Avengers to protect the Earth. Unfortunately the story of the Red Guardians in most cases lead to the death of the person carrying the weight of the red shield and Petkus was also killed by the Dire Wraiths in an attempt to resurrect a comrade.
David Harbour is going to portray Alexei Shostakov.
