Premise
After a fight against the Horsemen of Apocalypse, the Avengers work alongside the X-Men to stop corrupt colonel-turned-terrorist William Stryker, who is allied with A.I.M. to inflict the genocide of Mutants. The Avengers are also aware that Stryker will soon push his hatred of Mutants so too far that he will unwillingly unleash Ultron, an Hydra A.I. created decades ago by Arnim Zola who is determined to get his own revenge against all organic life (both humanity and metahumans). At the same time, Hulk is spending time with young mutant Humberto Lopez (also called Reptil), a young Mutant boy who feels neglected by everyone else (even by his parents) due to the Mutants' troubled past with Humanity, and helps him find his place in the world.

Plot
It all starts with Wolverine and his fellow X-Men (Jean Grey, Beast / Dr. Hank McCoy, Storm / Ororo Munroe, Cyclops / Scott Summers, Kitty Pryde and Iceman / Bobby Drake) battling the Horsemen of Apocalypse (consisting of Archangel, Sabretooth, Psylocke and Molten Man), who plan to capture Professor Charles Xavier and Rogue and absorb their powers to resurrect their deceased master En Sabah Nur, who was destroyed years ago by the Phoenix Force. The X-Men are aided by Captain America, Spider-Man and Hulk, who help defeat the villains. Meanwhile, William Stryker is broken out of his cell by Hydra forces led by Baron Zemo, who has uses for him.

The X-Men are visited in the Xavier Institute by the Avengers, with exception of the Hulk, who was called by a civilian couple to look after their son Humberto Lopez, who is feeling neglected by the others due to his nature as a born mutant whose powers had manifested two days ago. After some talk, the Avengers and X-Men receive a distress call from Agent Phil Coulson, who informs them of Hydra's next schemes which are being supported by Stryker, who still longs to commit the genocide of mutants despite the world leaders having been convinced to create a campaign to have humanity coexist in peace with Mutantkind. Predicting that Stryker's obsessions will only create and unleash something far worse, the Avengers and X-Men set out to stop Hydra. Meanwhile, Hulk is having sometime with Humberto while assuring him that most of humans (with single exception of the corrupt ones) no longer have the same conflict they had in the past. Just then, they are ambushed by a Hydra-marked Sentinel unit, which was sent by Stryker to kill Humberto.

Hulk fights the robot to protect Humberto, who consequently joins the fight while showing off his abilities to turn any part of his body into any part of a dinosaur's body. After hearing of Stryker's plans through the robot's memory systems, Hulk sets out to regroup the Avengers as Humberto (calling himself Reptil) follows him. The Avengers and X-Men infiltrate Hydra's headquarters (where it was once the secret base of Stryker's Weapon X Program). They battle several Hydra soldiers and Sentinels as Stryker watches. He tries to escape through a helicopter, but is intercepted by White Swan, whom Stryker verbally mistakes for a descendant of Emma Frost and orders the Sentinels to attack her. And just as the Sentinels decline when they do not trace any mutant metabolism on her, Stryker hacks Hydra's Central computer and, against Dr. Zola's warnings, awakens its forbidden project. His plan, however, backfires when the Sentinels are taken over by Ultron, a A.I. robot created by Zola originally as an ally to Hydra in the World War II until he proved to be too uncontrollable and was forcibly shut down. Seeking revenge on his creators and all organic lifeforms for his long years of isolation, Ultron converts the entire base into a space station with the purpose to eradicate all life on Earth.

As the base begins to take off and set course to New York (where Ultron plans to convert on all technology to wipe out humans and metahumans present there), Hulk and Reptil manage to catch up and jump onboard. While the other Avengers and X-Men battle the converted Sentinels and White Swan and Kitty Pride work to find a way to sabotage the core (which is loaded with Vibranium), Spider-Man, Iron Man and Wolverine confront Ultron himself in a fight which takes place outside the base. Hulk comes to reinforce the trio as Reptil helps White Swan and Kitty disable the core and throw it into the depths of the ocean. Thor and Storm overload the engines with a lighting storm, causing the base to collapse into the oceans. The Avengers and X-Men escape with the apprehended Stryker as Ultron sinks into the oceans with the destroyed base and Zemo and Zola retreat empty-handed. As Stryker is taken to jail, the Avengers and X-Men pay their good complements with one another and their respect for Reptil for his heroic dedication as he is given a place in the Avengers Academy. As Humberto trains with his new friends, the Avengers voice their satisfaction with another success, although Spider-Man is unsure if they have really seen the last of Ultron yet. Scene shifts to the depths of the ocean where the Hydra base sunk, where a seemly destroyed Ultron is still functional.
