Inventor Howard Stark seemingly dies in a plane crash while investigating an ancient Chinese "Makluan ring". His son, Tony Stark, barely survives the crash when the armored exoskeleton-battle suit which Tony designed and built himself implants in his chest a device to sustain his damaged heart. Obadiah Stane takes control of Howard's company, Stark International, and begins weaponizing Stark's inventions. Tony moves in with family friend James "Rhodey" Rhodes and his mother, Roberta, and begins attending school. There, he meets classmate Pepper Potts who informs Tony that Stane is under investigation by the FBI for possible involvement in Howard's supposed death. When Tony goes to investigate in his armored battle suit, he ends up preventing a runaway train from crashing into Stark Tower; the media calls him Iron Man. A shadowy figure called the Mandarin, wearing a second mystical Makluan ring, vows to obtain the second ring now in Stane's possession.

Introducing Characters: Tony Stark, Howard Stark, Obadiah Stane, Patricia "Pepper" Potts, James "Rhodey" Rhodes, Roberta Rhodes and Mandarin

The Mandarin, shown to be an old man named Zhang, quarrels with his stepson Gene Khan. When Stane demonstrates his weaponized version of Tony's "Earth Mover" invention to a group of potential buyers, Tony, as Iron Man, destroys them. Meanwhile, Gene, having imprisoned Zhang, appears as the Mandarin and takes Stane's ring.

Introducing Characters: Gene Khan

As tensions mount between the Tong and rival criminal organization the Maggia, Gene enrolls in the Tomorrow Academy to be closer to Tony in hopes of learning more about the Makluan rings. When a team of Maggia thugs headed by Unicorn and Killer Shrike kidnap Gene, Tony, and Pepper, Rhodey remotely pilots the Iron Man armor to their rescue.

Introducing Characters: Maggia, Unicorn, and Killer Shrike

In hopes of exposing Stane as evil, Tony teams up with Blizzard, until he realizes that Blizzard wants to hurt Stane along with anyone else who gets in his way. As Iron Man, Tony reluctantly saves Stane, leaving Blizzard cryogenically frozen in Stark Tower.

Introducing Characters: Blizzard (Donnie Gill)

Whiplash seriously injures Pepper's FBI agent father, who is close to finding Mr. Fix. When Fix sends Whiplash after Pepper, Tony saves her, and reveals to her his identity as Iron Man. Iron Man defeats Whiplash by using a new, more powerful suit of armor to hurl Whiplash into an electrical transformer.

Two years ago, an astronaut named Ivan Vanko was lost in space while observing the Sun. In the present, he crashes back to Earth in New York City, having survived thanks to his Crimson Dynamo suit, which was designed to survive the harshest conditions imaginable. But after years in space, all Vanko wants is revenge on the people who left him behind...Project Pegasus. Iron Man is hard timed trying to fight the tough suit and decides to use brains over brawn. But as he ran low on energy, Pepper is able to locate Vanko's family and resolve the matter peacefully. Tony falls asleep in the armor on the way back to the armory.

Tony is still flunking school and is placed in the lead role of Hamlet (which ironically mirrors his situation). He learns from a holographic will of his father that he wanted him to have a normal life rather than letting the company be a burden on him. However, a Maggia member named Arthur Parks becomes the Living Laser through use of an experimental vest stolen during a raid. Iron Man is able to stop him and remove the vest but it had a lasting effect on the Laser, whose body turned to pure energy and resolves to take down Iron Man.

Note: Howard Stark (hologram version) mentioned that Rhodey's father was named David.

While sneaking into Stark Industries, Tony's Stealth Armor shorts out, forcing him to leave it in his father's vault which to his dismay has been stripped clean. To retrieve the armor before Stane can find it, Tony, Rhodey and Pepper set up with a school field trip to smuggle in replacement power cells. However with Tony barred from the building, it is up to Rhodey and Pepper to save the day.

Tony, his friends and Gene search the ancient ruins where his father first found one of the Makluan Rings and discover a carving explaining the history of the rings and that for each one there is a test established by the first Mandarin intended to determine the worthiness of his heirs and activate to each ring's power. In this case the test being one of wisdom, Gene assumes the key lies in choosing a book over a sword, but this only ends up bringing stone Dreadknight statues to life and splitting the group. Knocking Rhodey unconscious, Gene attempts to defeat the statues as the Mandarin but it is Tony and Pepper who realize the sword is the key to passing the test. After escaping the collapsing temple, they discover the sword contains a map to the next ring.

At a school science fair, Tony is approached by the Controller on behalf of A.I.M. and tricked into making a mind/machine interface work. The head of A.I.M., angered that this may compromise their M.O.D.O.K project orders all efforts on the interface to cease and Tony and the others exterminated. However, Tony has already been successful, allowing the Controller to take over his friends. Now Iron Man must step in and save the day, only to find his life being saved in the process by a girl named Whitney, who is revealed to be the daughter of his greatest enemy.

Rhodey becomes concerned over Tony's plans to increasingly weaponize the Iron Man armor using reverse engineered captured tech. Obadiah Stane offers to bail out Anton Harkov and Project Pegasus in return for the Crimson Dynamo armor which is upgraded to capture Iron Man, resulting in a pitched battle in the middle of the city that leaves Stane furious at the reckless endangerment of innocent lives. Having lost the battle and fallen unconscious, Tony is brought to Project Pegasus. Harkov and Stane then begin to analyze the Iron Man armor. With the help of Rhodey and Pepper, Tony manages to escape, only to return in the Dynamo Buster armor (which resembles the Hulkbuster Armor). He then uses a virus called 'Technovore' to destroy Pegasus' advanced AI Delphi, both to defeat the Dynamo and prevent Stane from acquiring detailed technical data on Iron Man. Tony is excited that he finally defeat one of his enemies, saying that what they need to win is better tech, weapons, and to stay ahead. Rhodey, on the other hand, reminds Tony that there is a line between good and evil, and that he just came close to crossing it. Though successful, there is an unexpected consequence, back at Project Pegasus having consumed all available data, the Technovore is close to burning itself out just as Tony planned. When Obadiah Stane is informed by his secretary that Anton Harkov is on the other line, Obadiah has her tell Anton Harkov that the offer is rescinded. But unknown to Tony one of Pegasus' projects were computer-controlled nano-mites. Using the connection Technovore takes control of the Nano-mites abandoning the computer, it forms a body and says one word "Consume".

Note: Owl has a verbal cameo as the school's mascot "Leland the Owl".

When Obadiah starts acting strangely, Iron Man investigates and discovers that "Obadiah" is being impersonated by a villain named Madame Masque. When she sets her sights on Iron Man, she begins to frame Iron Man of various crimes. It is revealed that Masque is actually Stane's own daughter, Whitney, using a stolen invention of Stark's deceased father to strike out at her own for neglecting her.

Tony and Gene team up to recover the third Makluan Ring, making Rhodey and Pepper furious at being left out even though Tony did so to protect them. When trying to claim the ring, Gene ends up awakening the ring's ancient robot guardian Ultimo (whose design bears a striking resemblance to Ultron). When Tony and his friends decipher the solution to the test of Courage, the Mandarin appears to reclaim his prize.

Tony upgrades the Iron Man exoskeleton software, and proceeds without testing it to clash with a newly equipped Whiplash, who now has a disc and better chains, courtesy of Mr. Fix. A momentary relapse in the armor's functionality is ignored, but makes critical changes to his suit. The suit has the ability to detect enemy power signatures, and when Tony attempts to find, and not fight, Mr. Fix, the armor displays sentient ability, putting itself into attack mode. It easily overpowers Whiplash with perfect maneuvering, and to the horror of Tony, destroys the facility that Mr. Fix occupied. Thinking that the Iron Man armor killed Mr. Fix and Whiplash, Tony and Rhodey decide that the armor needs to be taken care of, and the suit craftily lures Tony away, then attacks Rhodey. The armor decides that Tony's danger-seeking behavior is not healthy for him, and tells Tony that he is to be confined within the armor at all times. Tony resists, and damages the armor. Rhodey grabs a magnetic repulsor, and Tony jumps in the way of the blast the armor directs at Rhodey. Tony goes into cardiac arrest, and the armor sacrifices itself to preserve its creator's life. (Based on the storyline presented in Iron Man vol 3 #26-30)

Iron Man is tracking an international thief named Moses Magnum right to AIM's secret headquarters, but the Black Panther is after Magnum as well. Magnum stole something that belongs to the Panther, and the Panther aims to get it back, even if he has to go through Iron Man to do it. It is later revealed that Magnum had stolen Vibranium from Wakanda and killed the Panther's father in a revolt. The Panther eventually acknowledges that allowing other people to help him might be a better way to operate than keeping Wakanda's borders forever closed, as it might have saved his father's life if it had been done earlier, once Iron Man saves his life.

The Living Laser takes over a space satellite and threatens Earth. When Iron Man tries to stop him, he runs into Nick Fury and S.H.I.E.L.D. who inform Iron Man not to get involved, even though he is putting his agents at risk. Iron Man flies to space to fight the Laser, but Fury gives him a 20-minute window in which to defuse the situation before he sets a self-destruct in the station off to prevent the Laser from destroying New York. Iron Man eventually tricks the Laser into capturing himself and S.H.I.E.L.D. takes him into custody, Fury threatening to destroy Iron Man if he ever "does more harm than good."

A hit has been placed on Tony Stark, and the Ghost has come to collect. Tony cannot even see the invisible and untouchable Ghost coming, but he's got a guardian angel, whether he likes it or not: Madame Masque, telling him that her father hired the Ghost to kill Tony, she posed as Tony to keep him from the real Tony. And while Madame Masque battles the Ghost to protect Tony, Tony finds himself pushing away Rhodey and Pepper to protect them. But when Whitney is captured by the Ghost, Tony has to turn to the very best friends he pushed away for help. When Iron Man confronts Ghost, he tells him it was stupid of Ghost capturing Obadiah Stane's daughter, Whitney, and realizing that he was not hired by him. Eventually, Whitney pays the ghost off to stop hunting Tony.

Pepper realizes if she wants to keep Tony as a friend, she has to learn to start liking Gene Khan, who has been busy trying to negotiate peace as the Mandarin between his Tong forces and the Maggia. Pepper ends up in the middle of the conflict. In order save Pepper from Count Nefaria and the Black Knight, without revealing his secret, Gene calls Iron Man. When Iron Man interrupts the meeting, the Tong and the Maggia fight, leaving Iron Man against Black Knight. In the end, Gene saves Pepper, Count Nefaria and Black Knight got arrested and the Tong soldiers find out that the man they've been following is not the Mandarin.

The Technovore virus that Tony unleashed against Project Pegasus didn't burn out as intended. It has acquired the nanotechnology and is running loose in the Project Pegasus complex, assimilating any technology it can gets its hands on. It has taken on the shape of a robot, which bears resemblance to Spider-Man villain, Carnage. Meanwhile, Nick Fury sends some S.H.I.E.L.D. Agents to bring Tony to repair the S.H.I.E.L.D. Helicarrier's engines. It is also revealed that the Living Laser is dying and that S.H.I.E.L.D. intends to let him waste away as he was a villain. Rhodey goes to the Pegasus facility to check out a disturbance only to run into Technovore, when it gets a hold of Rhody's earpiece, it calls Tony so it can absorb the Iron Man armor. After the Pegasus scientist who was hiding in the building fled, Tony arrives. After exhausting every option, Tony activates the armor's self-destruct sequence, and abandoned the armor and ran for it. The explosion destroys both Technovore and the facility. Meanwhile somewhere in Russia, Anton Harkov leaves a plane. But unknown to him, a microscopic cell of Technovore's nanomite body still remains inside the fabric of his coat.

Note: Beginning with this episode, this episode began to air on NickToons (formerly called Nicktoons Network).

The fourth Makluan Ring has been found, and when Tony, Rhodey and Pepper rush off to collect it, Gene is left behind. And while Gene tries to track down his 'friends,' he's left alone with memories of his mother, the person who introduced him to his destiny, his birthright: the Makluan Rings. Actually claiming that birthright isn't so easy though, which Tony is finding out first hand. He's facing the fourth Guardian: the Firebrand, which possesses Pepper and Rhodey and attempts to erupt volcanoes all over the world. Rhodey and Tony pass the test with Gene's help and activating the ring. They arrive back home, as Tony has the ring on and cannot get it to do anything, but the Mandarin could.

The Living Laser is dying, and Tony Stark is trying to save his life. But fate has other plans. The Ghost has been hired by AIM to 'steal' the Laser. When the Ghost comes Tony realizes that it was AIM who hired the Ghost to kill him. AIM needs him to be a power source for their greatest creation, and when Iron Man arrives to rescue the Laser, he's too late. The Mental Organism Designed Only for Conquest is online. Not even Iron Man can withstand MODOK's mental power and MODOK immediately brings Iron Man to his knees and takes information from him, including his secret identity. When the Living Laser hears MODOK said that Tony is Iron Man he realizes that Iron Man had been trying to help him the whole time. Then he joins the fight just as MODOK is about to finish Iron Man and working together the two overpower MODOK and cause his memory system to crash so he forgets all the information he took from Iron Man. But after battle it becomes too late to save the Laser, Iron Man thanks the redeemed Living Laser for saving him and then he disappears. Meanwhile Tony loses faith in his father after learning from Nick Fury that he made weapons for S.H.I.E.L.D. but Roberta Rhodes reveals that Howard gave up making weapons and started helping people when Tony was born just to become "someone his son could be proud of" which restores Tony's belief in his father.

In Gene's limo, Gene, Pepper, Whitney, and Happy follow Iron Man (actually Rhodey, reluctantly trying the suit on Tony's insistence) until he crashes. Rhodey abandons the suit, and Happy, finding it empty, puts it on. Tony tries to convince, then force, Happy to stop playing around, but Happy refuses, believing that he is communicating with the "robot" Iron Man. When Happy crashes into a Tong treasury building, he finds Unicorn and Killer Shrike arming explosives to blow open the vault. Gene, as the Mandarin, protects Iron Man from Tong "ninja" troops, cementing their suspicions that he is an imposter. Whitney, as Madame Masque, slows the police response to the situation. After a struggle, the villains admit they are working for Mr. Fix, and Tony realizes that the bombs are powerful enough to destroy the city. When Tony fails to defuse them, Happy saves the day by simply breaking the central bomb in half; meanwhile, Madame Masque, as Gene, convinces Pepper to run to safety. Finally, Happy takes off the suit when Tony claims that it is about to explode.

When Tony responds to the Hulk's rampage in the Dynamo Buster armor, the Controller takes control of him to attack AIM. The Controller had been manipulating Rick Jones, friend of the Hulk, to the same end. The Hulk agrees to help save Iron Man, and finds him at AIM headquarters struggling against the Controller's attempts to force him to kill the wounded MODOC, whose mental attacks are powerless against a mind under the Controller's power. Hulk liberates Iron Man by destroying the controller disc. MODOC escapes, the Controller passes out, and Rick and the Hulk move on.

Note: In this episode at no point does the Hulk ever turn back into Bruce Banner, even when he is calm.

Poisoned by the experimental technology in the mask she uses as Madame Masque, a delirious Whitney tries to kill her father. Stane asks Tony to cure her, but the raw form of the ore he needs to do so can only be found in an abandoned arctic facility. Stane thaws out Blizzard and attempts to force him to retrieve the ore. Blizzard pretends to cooperate, but ultimately destroys the ore for revenge. In the Arctic Armor, Tony saves Stane from Blizzard and Madame Masque. Using ore from his cardiac implant, Tony cures Whitney, who wakes with no memory of the previous months.

Freed by the Tong, Zhang recovers the rings from Gene, then kidnaps Tony and Pepper, taking the fourth ring and destroying the factory above the Armory. Following Rhodey's information, Zhang proceeds to Machu Picchu where he forces Gene and Tony to activate the test for the fifth ring, "Sacrifice". When a dragon statue called Fin Fang Foom comes to life, the Tong flee, and Pepper manages to take the Mandarin's gauntlet and rings. Meanwhile, Rhodey, having stumbled across the War Machine suit, heads for Peru with the Mark I armor in tow, but a systems failure strands him in space.

Using remote control, Rhodey uses the Mark I armor to push himself back into Earth's atmosphere. Arriving at Machu Picchu, he attacks Zhang and the Tong helicopters, and then bursts into the temple. Tony suits up, revealing his identity as Iron Man to Gene. In an abortive attempt to pacify Fin Fang Foom, Pepper had thrown the rings into the dragon's mouth. Eventually, Gene allows the dragon to eat him, saving Pepper and passing the test; reemerging with the gauntlet and all five rings, he reveals himself to be the Mandarin. Furthermore, Gene admits responsibility for the attack on Stark's plane, and claims that Howard is alive and in his custody. After fleeing, confused and frustrated, Gene throws the rings, revealing a map to the locations of five additional rings.

In the Season 2 opener, Mr. Fix's mysterious new boss orders the abduction of 21-year-old multibillionaire Justin Hammer. But when Iron Man fights the new and improved Whiplash to prevent this, Tony's heart ends up critically damaged in the process.

With Stark International on the line, Tony (who is severely ill and injured) suits up in the all-new Mark 2 Iron Man armor to defeat Whiplash 3.0, Blizzard and Mr. Fix.

When Mr. Fix rematerializes the Living Laser on Justin Hammer's orders, unexpected complications split him into two separate halves. The evil and dark Half seeks out to destroy Iron Man and conquer the world while the good and light half tries to warn Tony and help him.

When Stane builds duplicates of the Iron Man armors called the Guardsmen (consisting of Force, Shockwave and Firepower), Tony must reveal they are frauds. But this causes the civilians to start hating Iron Man, as they believe that he is simply jealous of the town's new heroes.

Note #1: Pepper's crush is made obvious to Tony when in the lab Tony says "Pepper I could kiss you" and her response is "What is stopping you?" she blushes and Tony never responds. This displays the possibility of perhaps a new relationship in bloom in which Tony and Pepper begin to date.

When S.H.I.E.L.D. Agent Mallen is fired by General Nick Fury, Mallen takes the super-serum "Extremis" and mutates into a powerful maniac bent on revenge. When Iron Man tries to fight Mallen, he ends up defeated and in critical health ... and his only salvation would be a dose of the selfsame Extremis. However, the serum not only repairs his heart, but also gives him brand-new technopathic powers, now becoming one with his armor, and faces Mallen.

Note: Introduction of Mallen and the Extremis storyplot. Captain America is recovered by S.H.I.E.L.D. though still frozen in ice in this episode.
