Earth’s Mightiest Heroes: The 20 Greatest Avengers

8) Spider-Man

Traditionally, Marvel’s jewel in the crown, Spider-Man, has a long history of almost joining the Avengers but never officially becoming a member. In more recent years, however, events have led to Spidey properly signing up for the team’s roster. He allied himself with both Tony and Steve’s sides in Civil War and later was a founding member of the New Avengers in its wake. Peter has even found himself leading the Avengers on occasion. Not to mention that he’s finally allying himself with Earth’s Mightiest Heroes on the big screen now in the Marvel Cinematic Universe.

7) Black Widow

Originally an Iron Man enemy when she first appeared in 1964, Russian spy Natasha Romanoff AKA Black Widow later defected to the USA and joined S.H.I.E.L.D., eventually seeking membership on the team. What makes Natasha such a valuable team member is her incredible espionage abilities and world-class martial arts and gymnastic expertise. Sometimes, she’s also been enhanced by biotechnology that decreases her aging and increases her healing rate. Nowadays, the character is one of the biggest Marvel names around, thanks to Scarlet Johansson.
