This animated series follows the adventures of the superhero team The Avengers - primarily consisting of Iron Man, Thor, Captain America, the Hulk, Ant-Man (a.k.a. Giant-Man), Wasp, Hawkeye, and the Black Panther - as they team up to save the world from dangers far too great for one superhero to handle alone.
