During a battle with Kang the Conqueror, the Avengers are lured into a trap and teleported into 100 years into the future. On the heroes’ absence, J. Jonah Jameson organizes a new team of “heroes” called the Thunderbolts and, establishing a new order, forbids the vigilance of other heroes, much to the citizens’ secret displeasure. While the Avengers work to battle Kang’s forces and find their way home, Peter Parker continues his activities as Spider-Man in secret while teaming up with his college teacher and mentor Hank Pym and fellow college classmate Janet van Dyne / Wasp in finding a way to expose the Thunderbolts and bring back the Avengers, who are working on finding a way back by themselves with help from the Resistance against Kang's dystopian empire. Taking advantage of the Avengers’ disappearance, Hydra agents led by Arnim Zola plan to create a new Super Soldier Weapon using the DNA of metahumans channeled through a diamond stone. Though the Thunderbolts manage to stop Zola’s plan, the battle results in Peter’s step-cousin Gwen Stacy, who was among the citizens witnessing the weapon’s creation, getting injured and hit by one of the diamond’s scattering shards. As Gwen is given medical attention, Peter angrily vows that Jameson and his Thunderbolts will pay for the incident, although Pym still reminds him of Uncle Ben’s words about Justice over Revenge. Suddenly, Peter and Pym end up discovering an teleportation portal to the Nest of Helios, a Paradise Island ruled by Andrea Carter, the first host of the Light Side of the Phoenix Force, who offers them the mission to help resurrect the Island’s omnipotent guardian entity Light Phoenix in exchange of helping bring back the Avengers and end the Thunderbolts’ tyranny. The two accept and Peter is made a member of the new generation of the Phoenix Corps by a dying elder. As Peter leaves with the Tribe’s messenger Redwing and the Phoenix Corps’ commander Jean Grey to find the new recruits, Gwen is shown recovering from her injuries as the shard which was stuck in her merges with her and her eyes ignite energy light.

02) “Thunder War, Part 2: The Phoenix Reborn”
While the Avengers work with Arsenal and the Resistance against Kang’s empire to protect their world, Peter, Jean and Redwing go on a journey to find and recruit the chosen members of the Phoenix Corps (Bucky Barnes / Winter Soldier, Sam Wilson / Falcon, Betty Ross / Red She-Hulk and Inferno / Dante Pertuz). Meanwhile, Gwen awakens to discover that the diamond shard which merged with her has given her the powers of the metahumans Zola’s men captured and trains to make good use of them. At the same time, Mary Jane Watson and Felicia Hardy encounter Mantis, who had left the Thunderbolts after feeling mistreated and hated by them, and invite her to join Spider-Man’s side while teaching her to maneuver the abilities she was unaware of. Right after gathering the chosen recruits, Peter, Queen Andrea and the chosen recruits to the Corps start the focusing ritual in the Nest of Helios and successfully resurrect Light Phoenix as Mary Jane, determined to accomplish heroic acts like Peter did, offers herself to be the entity's host. Meanwhile, the Thunderbolts get a new member with a mysterious hooded young woman only known as the Oracle. Unbeknownst for them, she is actually Mary Jane as a double agent allied to Spider-Man. Furthermore, she obtains the resources the team will need to bring the Avengers back.

03) “Thunder War, Part 3: Avengers Reassembled”
Having fully assembled their team (consisting of Ant-Man / Scott Lang, Wasp, Felicia (on her moniker of Black Cat), Gwen (who had taken the moniker of White Swan), Mantis and the Phoenix Corps), Spider-Man and Doctor Pym are given by Mary Jane the tech they need to bring back the Avengers as well as footage of Jameson's confession of his part in Kang's plans against the Avengers. Pym is also able to contact Iron Man, who likewise prepares the same device so they can be connected. Spider-Man and Wasp manage to infiltrate the Daily Bugle Communications building and, with the archive footage Mary Jane (disguised as the Oracle) passed to them, they manage to broadcast the truth about J. Jonah Jameson and the Thunderbolts for all New York citizens to see and hear: it was Jameson who allowed Kang to abduct the Avengers to fake his own “heroic deeds” and take control of all, and the Thunderbolts’ leader Citizen V is in reality Captain America’s great adversary Baron Zemo. The Thunderbolts hunt down Spider-Man until they are kept occupied by his teammates. Spider-Man and Doctor Pym reach for the Avengers Tower where they prepare the Time Portal. Learning of the outcome, Kang appears before them in an attempt to stop them until he is held back by Spider-Man and the “Oracle” (who changes to the form and mantle of Phoenix Princess) enough so that Pym can finish the device and bring the Avengers back to the Present. The united heroes defeat Kang, who is then imprisoned into a alternate timeline and entrapped into a endless Time Loop which he cannot get out from, and the Thunderbolts, who are then taken to prison alongside Jameson as Stark’s old friend and former bodyguard Happy Hogan is elected Mayor of New York City. As the world celebrates the return of the Avengers, Mandarin and Leader, who had been previously banished by the Thunderbolts, cross paths with Thanos, who has plans for them.

04) “Sinister Venom”
Following a fight with Spider-Man's old foes, the Sinister Six, the Avengers battle a Venom Symbiote, which ends up possessing the Six and controlling their bodies. All seems well after they defeat the villains and apparently destroy the Symbiotes, but the Avengers' real problems only begin when a surviving fragment of the Symbiote infiltrates the Avengers Tower, duplicates itself and possesses most of the heroes one by one. Spider-Man, Phoenix Princess, Black Panther (the only members who are immune to the organisms' influence) and Stark (whose armor is taken over by the Symbiotes) now need to find a way to free their teammates and stop the Symbiotes' rampage.

05) “The Last Valkyrie”
During a fight with Ulik and his army of Rock Trolls, the Avengers encounter Tarene Olson, a young girl who proves herself as worthy as Thor of wielding Mjolnir. After learning of her parentage as the descendant of the Valkyrior, a legendary force of female warriors who were killed defending Asgard from Hela long ago, Thor and his Asgardian ally Sif train Tarene on the use of Mjolnir while Spider-Man and Iron Man use a fragment of the Uru metal to forge a Mjolnir-themed weapon for her. The Avengers, however, must also focus their attention on the Destroyer (an ancient living weapon of Asgard), which is unwillingly unleashed by Hank Pym's old rival Darren Cross (who was planning to acquire the “perfect weapon” to ruin Pym Industries' business) and controlled by Loki to attack the humans. By the conclusion of the episode, Spider-Man suggests that the Avengers may start an Academy for young new heroes, to which they agree and start out with Tarene (who now calls herself Midgard Valkyrie) and Mantis as their first students.

06) “Madness in Space”
After a fight with the Mandarin and the Leader (who return to Earth after being banished by the Thunderbolts), the Avengers discover that the two are involved with the mad schemes of Thanos, who is searching for the Tesseract everywhere across the galaxy. Knowing the risks, Iron Man and Thor infiltrate Thanos' spacecraft, the Sanctuary II, to find out what the Mad Titan is up to and prepare to stop him at any costs. There, they also get to free and team up with Adam Warlock and Kree exile Mar-Vell, who were being held prisoners in the Sanctuary II for Thanos' purposes. Meanwhile, the Avengers work alongside Sam Alexander (a young boy who just became the newest human member of the Nova Corps) and S.W.O.R.D. Units to deal with the Chitauri, who were unleashed by Thanos to collect the most powerful metals of Earth to build his ultimate weapon.

07) “I'm Only Inhuman”
While the Avengers work with the Inhuman Royal Family to stop Maximus the Mad's schemes in Attilan, Spider-Man stays to look after and train Kamala Khan, a young girl and fan of the Avengers (mostly Captain Marvel) who developed her powers due to exposure to a Terrigen cloud unleashed by a mysterious meteorite which crashed in Midtown. Peter must also protect Kamala from Ronan the Accuser, who longs to commit the genocide of Inhumans on Earth in order to protect the Kree Empire from the “Inhuman menace”. At them same time, Stark discovers that Harley Keener and his cousin Ollie Osnick, two young boys from the Parkers' neighborhood in Queens, have donned prototypes of the Iron Spider suit and must look after them as well.

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.

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.

09) “Venomous Vengeance”
During a fight against the Super-Adaptoid (controlled by Tony Stark's business rival Justin Hammer), the Avengers discover that a fragment of the Venom Symbiote (which survived during the heroes' latest battle with it in the Avengers Tower) has bonded with former Daily Bugle reporter Eddie Brock, who is going out for a crime-fighting campaign of his own. But as the Avengers note, much unlike Peter's crusade as Spider-Man which is about Justice, Brock's crusade is about brutal revenge as Brock seeks to end the lives of all men in New York who wronged him, including the Green Goblin, who once gave Brock a “really bad day” to drive him crazy. The Avengers now need to do what they can to stop both Goblin's mad schemes and Venom's vengeful onslaught before their both foes will unwillingly create something worse. On the middle of the mayhem, Captain America encounters Tarene Olson's long lost twin brother Max, who developed Captain America's physical strengths due to exposure to the Super-Adaptoid's batteries, and must protect him from Green Goblin as well.

10) “Project Ultimate”
After taking over experiments and products from Oscorp, Red Skull and Arnim Zola kidnap Dr. Curt Connors and force him into helping with the creation of their own version of the Avengers for Hydra. Things go wrong when Ultron takes over their project to begin the creation of the Ultimates, leading the Avengers to jump to action and stop him at any costs.

Of course the Avengers still have bigger issues to settle when Doctor Doom and his forces from Latveria raid the U.S.A. in search of a new super-weapon which is being built in Hammer Industries. The new young heroes must now put what they learned to a test and prove themselves to help their teachers stop Doom's threat.

Obadiah Stane steals Tony Stark's old A.I. system J.A.R.V.I.S. and uses it to create a new android powered by a mysterious gem of infinite power to destroy the Avengers.

At the same time, the Avengers and the New Warriors work to stop cosmic-powered alien Firelord, who had managed to obtain a prototype of the Mind Stone to manipulate the minds of Fire-based villains (Scorcher, Molten Man, the Fire Demons of Muspelheim and a Green Goblin from another dimension) and plans to have Earth consumed by fire and smoke.
