If you pay close attention to the "Molecule Kid" episode, you see that Avengers Assemble is actually season three of Avengers: Earth's Mightiest Heroes. Also the return of Galactus, referring to the final episode of EMH. (I loved the cartoon WAY better as Earth's Mightiest Heroes). Not because of graphics, but the way that they treat the Hulk and the way they poorly operate. It's like all of their training went out the window with the new show.
Where am I going with this? Other heroes need cartoons too! I think it would be awesome if the continuation of this series was called Astonishing X-Men or something and it would tie in to Spider-Man, Avengers and Guardians. Same thing for the Fantastic Four.
I think we can all agree that the animated universe would get epic if Avengers Assemble, Ultimate-Spider Man, Guardians of the Galaxy and hopefully new Fantastic Four and X-Men cartoons had a two hour crossover or something.
Guardians looks good Marvel, but we should also get X-Men and Fantastic Four. You guys agree that they should be together? Or do you hate the Ultimate Spider-Man style cartoon?
