Phineas and Ferb: Mission Marvel

The entire Tri-State Area, and, possibly, the world, is at stake here!

Spider-Man, Iron Man, Thor and Hulk stand powerless after being struck by Dr. Doofenshmirtz's power-draining "inator." Once the Marvel Super Villains - Red Skull, Whiplash, Venom and M.O.D.O.K. - find out that Dr. Doofenshmirtz is responsible for robbing the Super Heroes of their powers, they seek him out and together create mayhem in Danville. Meanwhile, Phineas and Ferb do everything they can to restore the Super Heroes' powers before the evil villains take over the world.

Mistaking Doofenshmirtz for a pharmacist
The Comic-Con trailer has the announcer mistaking Doof for an "Evil Pharmacist". This is followed by a clip from Across the 2nd Dimension where he says, "Actually I'm an evil scientist..."

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".
 * 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.
 * Prior to this episode, the Marvel heroes were parodied several times on the show:
 * Spider-man: "Bowl-R-Ama Drama", "Phineas and Ferb Christmas Vacation!", "Quietest Day Ever", "Bee Story"
 * Iron Man: "The Beak"
 * Thor: "Thaddeus and Thor"
 * Hulk: "Let's Bounce"
 * This will also be the first appearance of the Hulk. Prior to this episode, he was parodied in "Let's Bounce".
 * Comic book creator Stan Lee cameos as a hot dog vendor in New York.
 * The hot dog stand that he runs is labelled "Excelsior! Hot Dogs". "Excelsior" is Lee's catchphrase.
 * Once again, Doof is mistaken for a pharmacist.

Production Information

 * This will be a special Season 4 episode and serve as the first animated crossover between Disney and Marvel, as formerly happened with the online game Club Penguin.
 * In 2009, Disney Company acquired Marvel Entertainment. "Our partnership with Marvel has yielded big returns this year - first with the launch of the Marvel Universe block on Disney XD, and now with production beginning on the Phineas and Ferb / Marvel special. To paraphrase Phineas himself: best year EVER!," said Gary Marsh, president and chief creative officer, Disney Channels Worldwide.
 * The storyboard of the episode's final act consists of 1801 pages.
 * A teaser trailer was released on May 15, 2013.

 * The first images were shown in the Disney Channel Summer 2013 promo.
 * On June 6, 2013, USA Today released the full-length trailer.
 * Visitors to the biannual D23 Convention will get their first look at the special Friday, August 9th.
 * In order to make them fit in with the Phineas and Ferb animation style, the Marvel characters' heads were slightly enlarged.
 * A 90-second sneak peak aired during the premiere of Marvel's Avengers Assemble on Disney XD on July 7, 2013.

International Premieres

Continuity

Allusions

 * The Lone Ranger - Most radio episodes of The Lone Ranger ended with the one being saved asking, "Who was that masked man?" Red Skull parodies this with the phrase, "Who was that masked...beaver...duck?"
 * Doctor Who - Writer Joshua Pruett tweeted that there will be a "Doctor Who" easter egg in this special.   Previously, there was a reference to that series in "Out to Launch".
 * Let's Call the Whole Thing Off - The classic Gershwin song is once again referenced. ("Bad Hair Day").
 * X-men - Stan Lee previously played a hot dog vendor in the first X-Men movie.
 * Fantastic Four (Johnny Storrm/Human Torch) or Ghost Rider - Dr. Doofenshmirtz says to the Red Skull "Is your head going to burst into flames or am I thinking of someone else?". This could be a reference to the Marvel Hero "The Human Torch" of the Fantastic Four. He could also have been referring to Ghost Rider.
