The team of Marvel's most elite heroes who assembled to save the world are known as The Avengers, Earths Mightiest Heroes. They were already a popular superhero team that then had a meteoric rise in popularity through their portrayals at the heart of the Marvel Cinematic Universe. With having their own big three in Iron Man, Captain America, and Thor, powerhouses like the Hulk, and agents like Hawkeye and Black Widow, the team lives up to their mighty epithet.
