Co-creators: Don Heck, Don Rico

When Stan Lee, Don Heck, and Don Rico brought this femme fatale to life, she was conceived of as a villain for Iron Man. But as events unfolded, she eventually defected to the superhero game and became a member of the Avengers. Throughout her career as a hero, the Black Widow has also aligned herself with the likes of Wolverine, Spider-Man, Daredevil, Captain America, and the Winter Soldier. She has evolved exponentially since her creation at the hands of Lee, but it’s because of his ingenuity and eye for diversity that she is still popping up in comics and movies.
