Marvel.com: Any last "The Avengers: Earth's Mightiest Heroes! teases for fans?
Chris Yost: If you've been following the Micro-Episodes, you've seen the heroes in action, facing HYDRA, the Wrecking Crew, the Red Skull, Klaw, Abosrbing Man--[and] we've hinted at Kang, Loki, Ultron and more--well, I can tell you that you haven't seen anything yet. The fight against Graviton is just the beginning. By the time we hit our November two-parter, you'll start to see the scope of this show.
The producers, writers, crew, we're all fans, and we all love the Avengers as much as you do. And "The Avengers: Earth's Mightiest Heroes!" is going to give you "a day unlike any other."
