Marvel's Ultimate Spider-Man - Season 1

High school student Peter Parker has been fighting crime in New York City as the masked vigilante Spider-Man for one year. Nick Fury, director of international peace-keeping agency S.H.I.E.L.D., approaches him with an offer to train with S.H.I.E.L.D. and become part of a new superhero team that is being assembled. Spider-Man at first declines the offer, but after his school, Midtown High, is attacked by the Frightful Four (a super-villain team consisting of Wizard, Thundra, Klaw, and Trapster) on behalf of Doctor Octopus, he starts to wonder if he really should have declined.

Spider-Man accepts Nick Fury's offer to train with S.H.I.E.L.D., and is put together with four other teenage superheroes: Nova (Sam Alexander), White Tiger (Ava Ayala), Power Man (Luke Cage) and Iron Fist (Danny Rand). Doctor Octopus sends the Frightful Four after Spider-Man again, and while Spider-Man doesn't initially get on with his new teammates, he has to learn to work alongside them to defeat the Frightful Four.

A childish argument between Spider-Man and Nova gets their entire team grounded. To prove themselves to Fury, the super-youths go through S.H.I.E.L.D.'s database of the most wanted supervillains to see who they can defeat and apprehend in order to impress Nick Fury. When the choices Batroc the Leaper, Blizzard, Melter, MODOK, Toad, Whirlwind and Lady Porcupine prove unpopular, Spider-Man and his team go to Latveria to track down Doctor Doom. The young heroes capture Doom, but things take a turn for the worst when Doctor Doom tricks the team into taking one of his Doombots aboard the Helicarrier.

Using DNA from a sample of Spider-Man's blood, Doctor Octopus creates an artificial, symbiotic life form named Venom. Driven by its desire to bond with Peter, the creature escapes from the laboratory, tracks him down to a house party and wreaks havoc, jumping from host to host and possessing each of Peter's teammates. At the end, Harry Osborn finds a sample of the venom and trains it.

After a fight with the Living Laser, Spider-Man meets Iron Man, a superhero he idolizes. Impressed by Spider-Man's scientific knowledge, Iron Man builds him a high-tech armor suit called the Iron Spider, which is equipped with an array of powerful weaponry. Despite lacking the necessary skills and having no control over the suit's functions, Spider-Man becomes increasingly smug about his new equipment, which puts a strain on his relationship with the team.

Taskmaster goes undercover and infiltrates Peter's school to seek out Spider-Man. Spider-Man and White Tiger must put their differences aside and find a way to defeat an opponent who can mimic all of their physical abilities.

Spider-Man agrees to a video interview with aspiring news reporter Mary Jane Watson, but the interview is interrupted when the Incredible Hulk appears in Manhattan and goes on a destructive rampage. Mary Jane continues to film as Spider-Man tries to stop the Hulk. Unbeknownst to either of them, something much more dangerous is hiding out of sight and that something is called Zzzax.

A mysterious new superhero dressed in black and with similar abilities to Spider-Man appears in New York, and attracts positive public attention. Peter suspects the new hero to be Venom, but his teammates dismiss his suspicions as jealousy. Peter then discovers the hero's true identity, his friend Harry Osborn, bonded with the Venom symbiote, and he tries to persuade Harry to get rid of it before it corrupts his mind and turns him evil.

During a school field trip to a museum, Danny translates the engraving on an ancient Norse rune stone and accidentally summons a Frost Giant. The Norse thunder god Thorarrives to aid Spider-Man's team, but magic from a medallion around the Giant's neck turns Thor into a talking frog. The team follow Thor to Asgard, where the power-hungryLoki is working with the Frost Giants to seize the Asgardian throne.

After Spider-Man and Wolverine apprehend the mutant Mesmero, the vengeful supervillain uses his mental powers to switch their minds, creating a serious identity problem for the two, as different heroes when Sabretooth comes to town.

Venom resurfaces using Harry as his host again. This time, Venom is targeting Harry's neglectful father Norman. While Norman does not want his potential secret weapon damaged, Spider-Man is confronted with the dilemma of choosing between helping Harry on his own or putting his trust in his teammates, who have orders from Fury to finish Venom off.

After a fight with Whirlwind, Spider-Man insists on a weekend off from Nick Fury and S.H.I.E.L.D. However, Doctor Octopus chooses this very time to attack Spider-Man when his job comes under threat from Norman Osborn.

The population of New York is plunged into a mysterious sleep, but Iron Fist manages to keep both himself and Spider-Man awake with chi energy. They seek the help of sorcerer Doctor Strange, and he explains the spell is the work of the demon Nightmare. To break the spell, the heroes have to enter the Dream Dimension and defeat Nightmare, facing the physical manifestations of their deepest fears and insecurities in the process.

Peter Parker struggles to split his attention between completing his science fair project with Luke Cage and combating Juggernaut. In his desperation concerning the former, he decides to "borrow" one of Dr. Connors's inventions called Awesome Android, which becomes an (quite literally) even bigger threat to the city.

The Helicarrier is commandeered by Zodiac, an elite criminal organization led by Scorpio, who imprison Nick Fury, hack into S.H.I.E.L.D.'s database and set the ship to self-destruct. Spider-Man is left as the only person who can save Fury and stop Zodiac before they obtain valuable data and the ship self-destructs over New York City.

Spider-Man's harshest critic, outspoken news magnate J. Jonah Jameson, is targeted by the Beetle, a villain equipped with an array of high-tech weaponry. Much to Peter's annoyance, Fury tasks the team with guarding the Daily Bugle building, but when Mary Jane tells Peter she is meeting Jameson for a job interview, he tries to stop her entering the building in case the Beetle attacks.

When Midtown High School has a snow day, Agent Coulson orders Spider-Man and his team to report to a S.H.I.E.L.D. Arctic base for winter survival training. They instead go against their orders and sneak off to a deserted tropical island (which Nova finds on the S.H.I.E.L.D. database) for a vacation. However, while the island seems like a beautiful paradise, something sinister is lurking in the sand and does not want its new "play-mates" to leave again.

Spider-Man's team fight the Wrecking Crew, but they end up unintentionally causing massive amounts of property damage. Fury assigns them to clean up their mess by working alongside Damage Control, a clean-up company that specializes in clearing collateral damage caused by superheroes. Spider-Man is frustrated by this seemingly boring assignment, but he begins to suspect criminal activity within Damage Control when he notices their CEO Mac Porter acting suspiciously.

After Hulk falls sick with an alien infection caused by the Phalanx, Spider-Man, tries to hide him at his house from the Phalanx, Nick Fury and Aunt May.

Loki gets revenge on Spider-Man by turning him into a pig using an enchanted hot dog. With the help of Thor and the entire S.H.I.E.L.D. force, "Peter Porker" must survive an Asgardian boar hunt led by Executioner across New York City.

Peter Parker is shocked to discover that Midtown High is putting on a Spider-Man musical starring Flash Thompson as Spider-Man. Things get dangerous when Trapster mistakes Flash for the real Spider-Man.

Doctor Octopus hacks into Iron Man's armors and sends one to kill Norman Osborn. While Norman blames Iron Man for the attack and threatens legal action, Spider-Man recovers a tentacle from an Octo-Bot and learns more about Doctor Octopus' history with both Oscorp, Doctor Connors and Norman himself. Doctor Octopus then attacks the Helicarrier in an arc reactor-powered suit of armor, created from a replica of Tony Stark's own arc reactor, and abducts Norman and Harry, so Spider-Man dons the Iron Spider suit to save them.

When Spider-Man loses Captain America's shield, he has to team up with the First Avenger to retrieve it, but they discover that Doctor Doom has it and doesn't want to give it back.

Peter is horrified when Aunt May goes on a date with his principal and secret S.H.I.E.L.D. handler, Agent Phil Coulson. Things get even more complicated when the high tech assassin, The Beetle, returns.

Doc Ock and Norman Osborn's plans collide, leading to the creation of a dangerous new foe: The Green Goblin.

Spider-Man leads his team in an epic battle to protect Harry Osborn from the Green Goblin, but even S.H.I.E.L.D. can't protect them when the Goblin teams up with Venom.
