The Avengers are a group of Earth's mightiest heroes who have banded together to deal with threats that no single hero could handle.
The original Avengers found the frozen Captain America who, upon wakening, joined them. Together they faced several villains, including the Masters of Evil.
Captain America would later lead a new Avengers roster formed by Hawkeye, Quicksilver, and Scarlet Witch.
First version of the team outside the comics.
