Marvel Disk Wars: The Avengers

Akira Akatsuki is excited to learn that his father, Nozomu, has completed his two year project for Stark International and has invited him and his older brother, Hikaru, to the Raft. After narrowly missing their flight, Akira and Hikaru are escorted to the Raft by Pepper Potts, courtesy of Tony Stark. During this time, a special presentation on the Raft is being held with several superheroes and VIPs in attendance, including three children, Edward Grant, Chris Taylor, and Jessica Shannon. Upon reuniting with his father, Akira is not particular happy that Tony is taking credit for Nozomu's project, the DISK system, which is designed for capturing supervillains, though Nozomu's assistant, Peter Parker, assures Akira it is because they wanted to protect them. Unbeknownst to anyone, mysterious characters sneak into the cells of the supervillains and help them escape by storing them inside the aforementioned DISKs. Whilst Edward, Chris, and Jessica sneak off to try and get closer to their favorite superheroes, Loki suddenly appears above the Raft and uses the DISKs to unleash supervillains all over the island. When Akira, Hikaru, and Nozomu are attacked by the Crimson Dynamo, who is looking for an 'installer', they are assisted by the arrival of Spider-Man.

After Spider-Man deals with the Crimson Dynamo, Nozomu gives the biocode installer to Akira and Hikaru, urging them to escape with Spider-Man to the heliport via an escape route, where they run into Edward, Chris, and Jessica. Meanwhile, as the other superheroes try to deal with the crisis on the island, S.H.I.E.L.D. headquarters is also attacked by supervillains, prompting Nick Fury to step into action. As Spider-Man is separated from the group when he is confronted by the Green Goblin, King Cobra takes Pepper hostage, leaving the heroes unable to put up any resistance against Loki, who uses the DISKs to imprison many of the heroes; moving on to Iron Man, Thor, Captain America, and Wasp. As Akira states his desire to save Pepper and the heroes, Hikaru comes up with a plan.

In an attempt to free Pepper, Akira attempts to trick King Cobra under an avalanche of crates, but fails. Chris arrives with a forklift and knocks the crates down, but King Cobra slips out. While Loki is in the middle of imprisoning the rest of the heroes, Iron Man frees himself and takes down King Cobra, while the kids free Pepper. The celebration is cut short when Loki arrives with Tom and M.O.D.O.K., who destroys the biocode installer. At the same time, S.H.I.E.L.D. is detained by Cottonmouth. Iron Man tricks Loki into firing a burst of energy that supercharges the remains of the installer, integrating a biocode into each of the kids. Tom traps Iron Man in a DISK, which is then taken by Spider-Man, who instructs Akira to send Iron Man out to finish the job. Akira and Loki's wristbands make contact with each other during a scuffle, causing all the DISKs in the immediate area to fall into a pocket dimension. Loki withdraws with Tom, and Nick Fury arrives at the scene after the battle and takes Akira and Hikaru into S.H.I.E.L.D. custody.

After the events at the Raft, Akira and Hikaru are taken aboard the Helicarrier while the other three are sent safely home. There, Nick Fury and a tiny hologram Iron Man (from inside the red DISK) reveal that because the biocode installer was damaged when it installed a biocode in the kids, the kids have a Limited Biocode, which only allows the released heroes to be outside the DISK for a few minutes and also requires hours to recharge. A man by the name of Senator Robert enters with incriminating photos of Fury, Tim, and Loki, leading to Fury's arrest and the temporary decommission of S.H.I.E.L.D. During all this, Spider-Man has recovered the DISKs containing Thor, Captain America, Hulk, and Wasp. Robert denies permission for S.H.I.E.L.D. to intervene when Lizard is seen on a rampage, leading Akira, Iron Man, and Spider-Man to intervene on their own. After Lizard is D-Secured, Iron Man runs out of time and a blonde masked woman (Rosetta Riley in disguise) sends out Diamondback to finish the job with the other two. Meanwhile, Hawkeye approaches Hikaru with a DISK wristband and offers him the chance to help off the radar.

Hikaru accepts Hawkeye's offer and parachutes down to a building near the scuffle with Diamondback against direct orders from Robert and Hill. With a little help from Akira, Hawkeye manages to leave Diamondback distracted long enough for Hikaru to stop the disguised Riley from stealing more DISKs from within a bank. Unfortunately, Riley sends out King Cobra to send Hikaru flying. After being caught by Spider-Man and handed Thor's DISK, Hikaru releases Thor, who interrupts King Cobra's offer to finish the kids off in exchange for permanent freedom with a hammer toss. Diamondback throws a fragment bomb diamond to ensnare everyone, but Thor uses a whirlwind/lightning combination to destroy the bomb and force Diamondback to surrender. Riley is forced to withdraw King Cobra and escape with Tim and M.O.D.O.K., as Hikaru and Thor introduce each other formally. Later, Pepper and Iron Man give Akira and Hikaru a place to stay in New York while the crisis continues. Robert mulls over S.H.I.E.L.D.'s failure with his reflection, and in said reflection is the face of Loki.

Spider-Man tries to convince Chris to help out with the DISK effort, but Chris refuses due to sheer lack of interest. Spider-Man begrudgingly admits defeat in the manner, considering how Ed refused due to overwhelming cowardice and Jessica due to being preoccupied with luxuries. After tossing Captain America's DISK to Chris regardless, Spider-Man is attacked by Joel and Abomination. The two manage to get away with the DISKs containing Wasp and Hulk, as well as Spider-Man himself. Meanwhile, Jessica and Ed are captured and locked up in a frigate by Menino. After Chris escapes Joel with a little help from Iron Man, Captain America confers with the team from within his DISK until Chris disconnects the wristband. Chris, remembering an argument with his parents about his uncertain future, decides to rejoin the team after seeing the Hulk on the news. Hulk, under secretive alchemic mind control by Diablo at the command of Menino, goes on a destructive rampage, forcing the team (including Chris) to go into action. While Jessica and Ed use their wits to find a way out of their cell, Iron Man and Thor are easily defeated by Hulk, who sees them as monsters of their own. With all the adrenaline overriding his uncertainty, Chris finally releases Captain America, who prepares to stand and face the still-rampaging Hulk.

Captain America begins to face Hulk, still on a rampage from Diablo's alchemic control, and starts by playing defense with his vibranium shield to gauge the situation. While Hulk is distracted, Akira and Hikaru recall Iron Man and Thor, who desperately needed time to recover. After forcing Hulk to tire himself out, Captain America goes from playing defense to outwitting Hulk to forcing him into a test of endurance, which Hulk loses. Akira secures Hulk in a new DISK, freeing him from his control. Meanwhile, Jessica and Ed escape their room on the frigate to where Spider-Man is being kept, and are found by Tim. Jessica takes out Wasp's DISK and a wristband, having snuck through the air vents to the room where they were kept, and releases Wasp. Despite Tim's intervention with an extremely arrogant M.O.D.O.K., Wasp frees Spider-Man and helps Jessica and Ed escape while Spider-Man decides to stay and keep M.O.D.O.K., Diablo, Abomination, and Whirlwind. As King Cobra closes in on their position in the air shafts, Jessica and Wasp send Ed to put out an S.O.S., which is picked up by the team. Seeing as how Whirlwind's tornado shielding makes it impossible for the Stark Industries Jet to make it through to the frigate, Akira tries D-Smashing Hulk, the only one who could make it through, but to no avail.

While trying to solve the puzzle of Whirlwind's tornado, Tony's mind flashbacks to when he and Nozomu (as well as clumsy assistant Peter Parker) were working on the DISK, and how talking about Nozomu's two sons helped come up with the classification systems, and how the party came into being. In the present, Iron Man explains how every hero in villain is split into one of the five classes, and that every Biocode is permanently locked onto the first one D-Smashed. This explains how Akira, locked to Tech-class DISKS, failed to D-Smash Hulk and then as an example Thor. On the frigate, Loki's five masked colleagues wait impatiently for him. While King Cobra captures Jessica and Riley takes the DISK containing Wasp, Iron Man asks to be released and sent to face the tornado with Hulk's DISK and a wristband in hand. After barely making it through alive with as much moral support as possible from Akira (despite the dissuasions from the rest of his team) Ed catches Hulk's DISK and attracts attention while heading the wristband. Biting King Cobra to get free, Jessica tosses Ed the wristband. Hulk, upon being released by Ed, faces against what's left against Diablo's alchemic control, knocking the villain into Whirlwind and knocking out the tornado. Captain America and Thor join Iron Man and Hulk on the ground, and thanks to some learned trickery Jessica brings Wasp back into the mix after getting her DISK back from Riley. With the heroes, villains, and their DISK-controlling partners all lined up for battle, Captain America finishes the episode with the iconic battle cry: "Avengers Assemble!"

Reunited at last on the frigate, the Avengers face off against Loki's cohorts while a harshly weakened Spider-Man struggles to survive below deck. Everything seems to be going well until Loki arrives disguised as Hikaru, tricking Thor into taking a Cane Blast point blank. Seeing the need to retreat, Loki orders Abomination to sink the Frigate, and then retreat. Jessica and Ed manage to capture a defeated Whirlwind, Diablo, and King Cobra while Captain America, Hulk, and Wasp try to find Spider-Man before it's too late. Spider-Man, dreaming of his "reported demise" and "triumphant return" to New York, wakes up to find the Avengers carrying him out of the ship. Later, while the team is having a celebration, Senator Robert closes in on Stark's penthouse in New York with a new warrant for either registration or arrest. However, the team is safely in one of Stark's Japan penthouses instead. Captain America offers Hawkeye to join the team, who declines due to his determination to take the corruption out of S.H.I.E.L.D. The next day, Akira and Iron Man find themselves in a dojo belonging to an old friend and bitter enemy of Stark's, the Silver Samurai.
