Phineas and Ferb: Mission Marvel

Let's get our hero on! is an upcoming special episode from the fourth season of Phineas and Ferb that will serve as an animated crossover between Disney and Marvel. It will premiere in the summer of 2013.

Synopsis
Spider-Man, Iron Man, Thor, and the Hulk enter Danville after Dr. Doofenshmirtz's latest "inator" scheme accidentally removes their powers and immobilizes them. Now it's up to Phineas and Ferb to team up with the Marvel Super Heroes to help them regain their powers and defeat Marvel Super Villains – Red Skull, Whiplash, Venom and M.O.D.O.K. – who are working together with Dr. Doofenshmirtz to use his power-draining technology to create mayhem.

Background Information

 * It will be the show's second one-hour special, following "Phineas and Ferb Summer Belongs to You!", and the fourth extended episode after "Phineas and Ferb Christmas Vacation!", SBTY and "Phineas and Ferb Musical Cliptastic Countdown Hosted by Kelly Osbourne".
 * Each of the characters wear a costume of some kind while saving Danville. The Avengers and Spiderman will wear their normal attire. Phineas and Ferb bring back the Beak, although the suit gets an arm ripped off in battle. Baljeet will somehow get Hulk-like powers, for he is seen as a big green monster in some of the trailors. Buford will dress in his bear suit, that now has a capital B on the front, along with gloves and a cape. Candace supposedly reprises her Dangeraffe comstume, but it has not been confirmed. Isabella has not been seen with a costume, but has been seen teamed up with Candace in several shots of the "Busting" trailer.
 * Dan Povenmire revealed in an interview that Doofenshmirtz creates the "power-drain-inator" with the intention of draining his brother's "power" as mayor of Danville, but it mistakenly hits Marvel's heroes. In the same interview, Jeff "Swampy" Marsh said that Candace's plot in the episode is going to involve her love to comic books and fan fiction.
 * This will be the first appearance of Spider-Man. Prior to this episode, he was parodied three times in the series canon ("Bowl-R-Ama Drama", "Phineas and Ferb Christmas Vacation!", "Bee Story").
 * Comic book creator Stan Lee cameos as a hot dog vendor in New York. He previously played a hot dog vendor in the first X-Men movie.
 * Second time Buford wears a bear suit. ("Buford Confidential")
