The list of "Earth's Mightiest Heroes" is limited, but what about the
Marvel Cinematic Universe's most powerful non-Avengers? Although Thor and Iron Man are capable of kicking some real bad guys, the Avengers aren't the only superheroes roaming the MCU. There are a lot of MCU characters that aren't Avengers, and when you add in the Marvel TV programs, there are a lot of people who would fit right in at the Avengers Compound.
The following Marvel characters might team up with Captain America and Black Widow to safeguard the Earth from both foreign and domestic threats, whether they're small-screen heroes like Jessica Jones and Luke Cage or fellow MCU big-screen members like Sif and Gamora. Below are the 16 most impressive Non-Avengers in the MCU so far.
