When Spider-Man, Thor, Hulk and Iron Man all lose their superpowers, there's only one thing to do: Exercise a bit of corporate synergy and guest star in the Phineas and Ferb: Mission Marvel summer special.

This trailer is unsurprisingly fun, but it surprisingly fat-packed with other Marvelites, including Venom, Red Skull, Whiplash and even MODOK, whom, for the love of all that is good and righteous, needs to have at least one scene with Doofenshmirtz, if only for posterity.
