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!"
