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 supervillains – Red Skull, Whiplash, Venom and M.O.D.O.K. – find out that Dr. Doofenshmirtz is responsible for robbing the superheroes of their powers, they seek him out and together create mayhem in Danville. Meanwhile, Phineas and Ferb do everything they can to restore the superheroes' powers before the evil villains take over the world.

Act I
Phineas, Ferb, Buford, Isabella, and Baljeet are surfing in the asteroid belt. The boys had collected cosmic rays to power the surfboards. The gang then surfs to a space station shaped like Phineas and Ferb's heads in which they are connected to Irving. Irving checks on the kids and Phineas asks if it's safe to land. He then wonders where Perry is.

At Doofenshmirtz Evil Incorporated, Perry is already trapped. Doofenshmirtz explains his power-drain inator, which makes people lose power. He wanted to take Roger's mayoral powers away so that Doofenshmirtz can be the leader. Doofensmirtz would be able to raise taxes and cut the ceremonial ribbon, in which he had special scissors for. He accidentally cuts the hydrolic pump, and Perry escapes. Agent P destroys the machine and Doofenshmirtz says that it's an extended episode and that he can't leave.

The broken inator fires once toward New York City, in which life was normal. Spider-Man comes and slings his way around. Hulk, Iron Man, and Thor are fighting Venom and Whiplash. When Spider-Man arrives, he joins the fight and M.O.D.O.K and Red Skull come in. Anti matter is being fired at the superheroes, but all the shots miss. That is when Doofenshmirtz's ray drains the heroes. They realize that they have lost their powers. Iron Man's suit was frozen, Spider-Man couldn't climb up walls, Hulk lost his strength, and Thor is no longer mighty. No one was able to carry Iron Man, so they went to get a dolly.

Back in Danville, the kids have arrived. Candace tries to show mom what they have done, but it was gone. She then asks why the boys aren't in space. Linda says her cue by asking if they want snacks.

On the S.H.I.E.L.D. helicarrier, the heroes are informed by Nick Fury that the ray came from Danville in the Tri-State Area and hit a satellite off a space station. Spidey questions if the space station belongs to S.H.I.E.L.D., but Fury answers that it belongs to Phineas and Ferb.

Back at D.E.I., Norm cleans up the debris from the destroyed inator. Doofenshmirtz wonders where the ray hit. A report on TV states that it hit the superheroes in New York. Doofenshmirtz gets so excited by this report that he blogs about it on the L.O.V.E.M.U.F.F.I.N. web site.

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!", "Phineas and Ferb Summer Belongs to You!" 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 Spider-Man 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 costume, 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. In addition, Doofenshmirtz will somehow become like MODOK. And Perry gains his own superhero outfit with rockets on the belt allowing him to fly.
 * 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"
 * 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.

 * 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.

Allusions

 * Phineas and Ferb Theme - In the opening title sequence, Spider-Man takes the place of Candace and parodies her line as "Aunt May, Phineas and Ferb are making a crossover!"
 * Star Trek - In the song "Surfin' Asteroids", outer space is referred to as the "final frontier", like the famous opening narration from the classic sci-fi TV series.
 * Charlie Sheen - After realizing he is responsible for the superheroes losing their powers, Doofenshmirtz remarks that he is "winning!", a catchphrase popularized by the actor during a series of 2011 interviews after being fired from his lead role on the sitcom Two and a Half Men.
 * 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 Storm/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.
