Debuting just a year-and-a-half ago, Avengers has already solidified itself as one of the best superhero adaptations ever—and we’re not just talking about animation. The show simultaneously pays homage to the Silver Age comics from the '60s and includes aspects from the modern books, managing to be completely fresh in the process. With the classic Avengers roster intact (like Captain America, Iron Man, Thor, Hulk, and Hawkeye), Earth’s Mightiest Heroes is all about big action and sprawling stories that often span multiple episodes and seasons.

But the show’s real highlight is its selection of Marvel Universe villains that spans from household names (Loki and Red Skull) to B-listers (Blizzard, Graviton, and the Bi-Beast). This show can be viewed as a marketing tool for this summer's Avengers movie, but we have a suspicion that Earth’s Mightiest Heroes may very well outdo what even the great Joss Whedon has planned.
