It was only a matter of time before the Disney toons got themselves mixed up with the greatest heroes of the Marvel Universe. The first two on that hit-list: Phineas Flynn and Ferb Fletcher.

USA Today reports that Phineas and Ferb: Mission Marvel will be premiering this summer on the Disney Channel. It's the first TV cartoon crossover between the House of Mouse and the House of Ideas. [Editor's note: Or is it the House of Mouse Ideas????? - Caleb]

The special features a whole host of characters from both universes: the titular Phineas and Ferb and their platypus pal Perry, teaming up with four of Earth's mightiest heroes: Iron Man, Thor, Hulk and Spider-Man. (Sorry, no Captain America. Dude's busy.)

No crossover would be complete without an all-star roster of villains, and the Mission Marvel event promises to bring the bads: Red Skull, Whiplash, Venom and M.O.D.O.K. come to Phineas and Ferb's hometown of Danville to battle their superhero rivals, rendered powerless thanks to the nefarious Dr. Heinz Doofenshmirtz.
