The Super Hero Squad Show - Season 1

Mole Man unleashes Megataur, Tricephalous and Manoo on Superhero City while searching for a fractal buried deep beneath the ground. The Super Hero Squad tries to stop both him and his minions, but Mole Man still has Fin Fang Foom waiting in the wings.

Reptil joins the Super Hero Squad and Wolverine is assigned to be his mentor. He immediately gets to prove his worth as the Squad races to stop Doom and the Wrecking Crew obtaining a hidden fractal.

Dr. Doom drains the cosmic power of the Silver Surfer in order to merge the three Infinity Fractals he has into an Infinity Dagger.

During a chaotic battle with Klaw and Screaming Mimi, a fractal's cosmic power turns the Hulk into the Gray Hulk. While Falcon and the Wasp babysit this unlikable, brainy Hulk, the Squad chase down the Lethal Legion in a battle to save Super Hero City.

Supernatural wackiness is turning the city (and the Squad) upside-down. The Squad goes to the mysterious Dr. Strange for help, but Strange tricks them into battling the dread Dormammu. It seems a wayward fractal is stuck in the Eye of Agomotto – but can the heroes possibly free Dr. Strange from the fractal's influence, defeat Dormammu and rescue the city from an army of Mindless Ones, all at the same time?

When a bratty 3-year old girl wears a fractal tiara, she gains terrifying power over reality itself. Mayhem reigns for heroes AND villains. But the Heroes For Hire are on the case to help the Squad find her father and stop Doom's plan to use this chaos to his advantage.

A mysterious new villain, Scorpio, outwits the Squad and allies himself with Doom. Soon enough, Scorpio is leading the villains in a quest to steal Stark's most powerful tech. But neither heroes nor villains know that Scorpio is really Nick Fury, the enigmatic leader of SHIELD.

When the Helicarrier is embarrassingly smashed, the Squad needs to find a place to crash. The team proves none too welcome at Stark Industries, the Punisher's battle van and Reptil's bedroom. Dr. Strange takes them in, but they dread a creepy, wacky night in his Sanctum Sanctorum. And thanks to the Enchantress, there is even more magical mayhem than they bargained for.

Doom's ally, Egghead, hatches a scheme to steal a fractal in the Squad's Helicarrier by shrinking to insect-size. Fortunately, the Squad can count on Ant-Man to help them chase down the villains at micro-scale. But being super-small leads them into some very unpleasant places, including Hulk's nose.

When he is tired of all he can take with the Super Hero Squad, Wolverine joins up with the international All-Captains Squad (consisting of Captain America, Captain Australia, Captain Brazil, Captain Britain, and Captain Liechtenstein) as Captain Canada where he helps them fight Plantman in the Amazon. Meanwhile, the rest of the Super Hero Squad have an embarrassing encounter at Ringmaster's circus when Doctor Doom sends Abomination and M.O.D.O.K. to recruit Ringmaster.

With some of the members on vacation, Iron Man, Thor and Hulk help out the Fantastic Four when Super-Skrull and his fellow Skrulls invade Super Hero City. Meanwhile, Thanos and Doctor Doom form an alliance in order to obtain a specific artefact from the Baxter Building. While the Fantastic Four and the other Super Hero Squad members are fighting the Skrulls, Falcon and H.E.R.B.I.E. defend the Baxter Building from Abomination, M.O.D.O.K., and Trapster.

Black Widow joins the Super Hero Squad and shows that she can hold her ground against Abomination, M.O.D.O.K., and Screaming Mimi. Unbeknownst to them, she is really Mystique in disguise sent by Doctor Doom to steal the Infinity Fractals. When Mystique (alongside Abomination, Klaw, M.O.D.O.K., and Toad) nearly gets the Infinity Fractals held at the Vault, the Super Hero Squad get an unlikely assistance from S.H.I.E.L.D. Agent Songbird (who had been undercover as Screaming Mimi all along). 

M.O.D.O.K. and Loki conspire to overthrow Doctor Doom and take his place as leader of his allied villain group after M.O.D.O.K. eats one of the fractals. In order to stop M.O.D.O.K. and Loki, the Super Hero Squad and Storm must team up with Black Panther and an unlikely ally... Doctor Doom.

Enchantress uses a spell in order to make Thor fall in love with her. Instead it backfires causing Ms. Marvel to fall in love with M.O.D.O.K. This causes S.H.I.E.L.D. to have Hawkeye take out Ms. Marvel before M.O.D.O.K. brings her to Doctor Doom's side. At the same time, Executioner plans to defeat Thor in order to get Enchantress to love him. Also, Thor falls in love with Valkyrie.

Baron Mordo possesses Iron Man turning him into the Iron Menace and escapes from the Dark Dimension, he plans to take over Super Hero City and Villainville. Wolverine, Falcon, Redwing and Abomination end up under Baron Mordo/Iron Man's control.

Doctor Doom and M.O.D.O.K. reluctantly help them when Iron Menace takes control of Abomination.

War Machine teams up with Iron Man when Doctor Doom, Crimson Dynamo, and Melter band together in a plot to eliminate Iron Man. Meanwhile, Wolverine and Reptil face off against Abomination and M.O.D.O.K. in a game of golf.

When a smilodon is brought to Super Hero City from the Savage Land, a mysterious jungle lord named Ka-Zar shows up stating that the smilodon is actually his companion Zabu. When the Super Hero Squad encounter Ka-Zar, they learn of his mission and help him rescue Zabu. Meanwhile, Doctor Doom sees the Star Quartz (which will bind and merge any metal in the presence of Vibranium) around Zabu's neck and sends Toad, Thunderball, Sabretooth, and Batroc the Leaper to steal Zabu in a plot to reforge the Infinity Sword.

Captain America sends Wolverine back to Xavier Academy to get his diploma and finish his remaining credits. Reptil tags along to see what Xavier Academy is like and meet the X-Men. To make matters worse, Ringmaster shows up and hypnotizes the entire X-Men team in order to find an Infinity Fractal for Doctor Doom.

The Mayor's re-election bid goes awry when Egghead wins by a landslide (thanks to a little mass mind-control). But his reign at city hall makes life in Super Hero City a bureaucratic nightmare for heroes and villains alike. Wolverine and the Mayor are up against every hero and villain in a desperate attempt to free everyone from Egghead's control and stop the villains' planned invasion.

Loki convinces Doctor Doom to invade Asgard with Loki's army and persuades him to let him borrow Abomination, M.O.D.O.K., Klaw, Melter, and Sabertooth into helping him. Sif gets Thor (with the help of Falcon, Reptil and Wolverine) to help fight the Lethal Legion. Meanwhile, Iron Man, Hulk, and Silver Surfer try to break into Villainville to steal all of Doctor Doom's fractals.

Magneto is in town with his children Quicksilver and Scarlet Witch who he has brought into a sinister plot to steal the Infinity Fractals at the Vault on behalf of Doctor Doom. During the first fight, Falcon develops a crush on Scarlet Witch after she heals Redwing.

Doctor Doom sends his "Team Toxic" (consisting of Pyro Trapster and Zzzax) out to the North Pole. His plan is to have them construct the super-spinner machine in order to spin the Earth enough to send Super Hero City into a space. Flatman and Reptil talk about the polar ice caps, all of a sudden the world starts flooding. Trapster has set off the super-spinner machine's self-destruct sequence causing damage to the polar ice caps. Now Iron Man must convince Iceman to help save the day.

It's Captain America's birthday and all he wants to do is celebrate it with his fellow Super Hero Squad members and Nick Fury. In order to show his minions what real villainy is like, Doctor Doom thaws out the WWII villain Red Skull. Captain America is not pleased to find his old enemy up to his old tricks while Doctor Doom is not thrilled about Red Skull's enormous ego.

Doctor Doom conquers Chthon's mystical dimension to free his mother Cynthia Von Doom (who changed her name to "Coco" because "Cynthia" is too drab). Though Doom ends up with Chthon's evil powers, he also finds himself dealing with his mother's monstrous nagging. Chthon comes to the Super Hero Squad and Doctor Strange for help. Meanwhile, Odin wants Thor to return to Asgard and orders him to handle his last-minute stuff on Earth before his time is up.

Stardust arrives on Earth to announce the coming of Galactus, devourer of worlds. Captain America and Ms. Marvel begin constructing a space ark to save the inhabitants of Earth while the SHS team up with the Fantastic Four to face Galactus.

Galactus is about to devour Earth and not even the combined power of all the Super Heroes (and even some villains) can stop him. Iron Man decides to gather all the Infinity Fractals and reforge the Infinity Sword.
