When
Advanced Idea Mechanics merged with the U.S. military to form American Intelligence Mechanics,
Sunspot, under the alias of
Citizen V, formed the U.S.Avengers with
Cannonball,
Pod (under the alias of Enigma),
Squirrel Girl, and
Toni Ho /
Iron Patriot as well as
Robert Maverick, the second Red Hulk. Their first mission puts them against the
Secret Empire, who were planning to destroy the United States inside their floating volcanic island base. Red Hulk crash-landed into the Secret Empire's floating volcanic island base, hard enough to destroy it. They are later approached by a future version of
Danielle Cage as Captain America, who tells them that her nemesis, the Golden Skull, came to their timeline to steal all the wealth. In
Miami, the team crash a charity gala only to discover that the wealthy CEO's were kidnapped and replaced by robots. During the battle, the team manages to defeat and capture the Golden Skull, who was wearing a golden armored suit. Danielle then goes back to her timeline, with the Golden Skull as her prisoner. Red Hulk is later sent to confront and defeat the
American Kaiju, who was attacking
Europe. During the hunt, he encounters
Deadpool, who was turned into a monster by mad scientist Dr. Vandoom. In the
Secret Empire storyline, Red Hulk encounters
Gorilla-Man and his army of Gorilla-Men. Gorilla-Man tries to remove Red Hulk's head to strengthen his Gorilla-Men army. Squirrel Girl manages to defeat Gorilla-Man and his army with her flying squirrels. Meanwhile,
Steve Rogers has a meeting with Roberto da Costa and scolds him for his recent actions and Cannonball decides to quit the team so he could live with his wife
Smasher and their son. Roberto then sees footage of the attacks in Manhattan, deep space, and in Sokovia. Cannonball returns to Earth only to discover the Alpha Flight Space Program, the
Guardians of the Galaxy, and the
Ultimates' battle against the
Chitauri. He joins the heroes in battle until one of the Chitauri dragons eats
Quasar and explodes, leaving both him and Quasar to be presumed dead. When Roberto assembles the team, he is attacked by one of his scientists who has allied with
Hydra. Meanwhile, the team arrives in
Washington D.C. to confront Hydra when Red Hulk begins to attack them due to being affected by mind-controlling nanomachines. When Pod and Squirrel Girl end up in Paris and are attacked by Hydra agents, they are saved by the Champions of Europe consisting of
Ares,
Captain Britain,
Excalibur,
Guillotine,
Outlaw, and
Peregrine. Meanwhile, Cannonball is found by an alien, among the debris from the Chitauri battle, where it is revealed that he is still alive. Red Hulk and Iron Patriot are captured and imprisoned when they see a nearly dead Roberto in one of the cells. While adjusting to prison life, Toni manages to heal Roberto just in time, when Hydra soldiers show up at their cell. Meanwhile, Cannonball is sold at an auction to a human named Howard Mason and Squirrel Girl and Enigma help the Champions of Europe in raiding a Hydra base. At the prison, Roberto manages to use his powers to defeat the guards and free Red Hulk from the nanites controlling him, while Squirrel Girl, Enigma and the Champions of Europe defeat the Hydra soldiers in Paris by destroying a
Helicarrier and releasing other captured heroes. Cannonball is later brought to an Earth-like American small town named Glenbrook. In the aftermath of the event, Roberto resigns from A.I.M. and is visited by Smasher who tells him that Cannonball is still alive. Meanwhile, Toni deactivates the Hydra nanites in Red Hulk's blood enabling him to return to normal and is asked by A.I.M. agents to be the organization's new leader. While traveling through space, Smasher and the U.S.Avengers are attacked by
space pirates known as Warpjackers. After a brief fight, the pirates tell them that Glenbrook is actually a planet named Kral X. Meanwhile, Cannonball is introduced to the townspeople by Ritchie Redwood, ruler of the planet. Upon discovering the people's troublesome behavior, Cannonball tries to escape only to be defeated and captured. Awakening in a dungeon, Cannonball meets other prisoners including a teen named Bugface. In the dungeon, Bugface explains to Cannonball that they are
Skrulls and that Kral X is a planet designed for those who are not fit to serve in the Skrull army. To make them happy, Kral X was designed to look like a 1950s American TV show, but when the show was cancelled and rebooted in modern times, the Skrull Ritchie neglected Bugface's suggestion to move with the times and sent him and other like-minded citizens to the dungeon to keep their lifestyles the way it is. After escaping the dungeon, Cannonball leads Bugface and the rebels against Ritchie until Smasher and the U.S.Avengers arrive to help. After sending Ritchie and his cohorts to jail, the U.S.Avengers head back home. == Literary reception ==
