The series features a team broadly based on the roster for the 1984 Avengers spin-off series The West Coast Avengers, composed of the Wasp, Wonder Man, Tigra, Hawkeye, and Scarlet Witch (Hawkeye and Scarlet Witch were also both in the Iron Man animated series as members of Force Works), led by Ant-Man (a.k.a. Giant-Man), with the Falcon and the Vision joining in the opening two-parter. For undetermined reasons (perhaps due to their rights being tied up in planned movie projects), the Avengers' "Big Three" were not regular fixtures in the series - Captain America and Iron Man made only guest appearances in one episode each, while Thor did not appear outside of the opening titles. Captain America appears in one episode, "Command Decision". The story involves the Masters of Evil and a flashback to Captain America defeating Baron Zemo. Iron Man, meanwhile in the episode "Shooting Stars", helps the Avengers thwart the Zodiac's plan to send radioactive satellite crashing to Earth.
