Yelena Belova (Earth-RSR)

"And for her bravery, Black Widow will be forever remembered as the spirit heart of the Winter Guard"

- - Black Widow being remembered by Red Guardian

Yelena Belova, codenamed Black Widow was one of the core members of the Winter Guard, and it's weapons specialist. A long time spy for Russia during the last years of the Soviet Union, Yelena was know for not being as ruthless as many of her comrades in battle, fighting for a larger peace of the world rather than just for the motherland. She was ultimately killed by Kano, a Australian spy on the Winter Guard, who was there by the orders of Tony Stark.

Yelena's death prompted her younger sister Natalia into becoming a new Black Widow and search for her sister's killer, making him pay.
