Disney and Marvel have teamed up for an animated crossover event that will see Marvel Super Heroes make a guest appearance in an episode of the Disney series, “Phineas and Ferb.”

“Phineas and Ferb: Mission Marvel,” which will air in summer 2013, is the first crossover television special for Marvel and Disney.

Working closely with Marvel’s creative team, “Phineas and Ferb” creators and executive producers are designing Marvel’s Super Heroes and Super Villains, to fit the world of the TV series.

Spider-Man, Iron Man, Thor, Hulk Red Skull, Whiplash and Venom will all make guest appearances in the television event.

“‘Phineas and Ferb: Mission Marvel’ is an exciting animated special for everyone at Disney and Marvel. Bringing together the worlds of Phineas and Ferb and Marvel’s The Avengers is a ton of fun for fans of both properties,” says Dan Buckley, publisher and president, print, animation and digital divisions, Marvel Worldwide. “It’s a thrilling opportunity for these two franchises to take advantage of each other in a way that may go beyond this one special.”
