Black Widow is the name of two superheroes who have appeared in various titles published by Marvel Comics: Natasha Romanova and Yelena Belova. Natasha Romanova first appeared as a villain for Iron Man in Tales of Suspense #52 (1964). Over several appearances in The Avengers, she reformed and became a superhero. She then underwent a redesign to her modern incarnation in The Amazing Spider-Man #86 (1970). Yelena Belova first appeared in Inhumans #5 before her formal introduction as a rival for Natasha in the first Black Widow series.
Titles feature Natasha as a main character unless otherwise noted. Series that feature both Natasha and Yelena as main characters are denoted by an asterisk (*), and series that only feature Yelena as a main character are denoted by a dagger (â ). Team books such as The Avengers and The Champions are not included.
Multiple tie-in comic books based on Black Widow adaptations have been published.
