In July 2016, Marvel announced the debut of the Champions, a team of teenage superheroes who became disillusioned with their predecessors and split off from the Avengers following the events of the 2016 "Civil War II" storyline.

[8] The series was relaunched in January 2019 under a new creative team with Jim Zub as writer and Steven Cummings as artist,[9] and ended in October 2019 with issue #10.

[11] The series was scheduled for another relaunch in April 2020 with writer Eve Ewing and artist Simone Di Meo,[12] but was disrupted due to COVID-19 pandemic.

[17][18] The Champions were formed following the departure of Ms. Marvel (Kamala Khan), Spider-Man (Miles Morales) and Nova (Sam Alexander) from the Avengers, when they became disillusioned by the behavior of their elders, specially in regards to the second superhuman Civil War.

[20] In their further early adventures, the Champions traveled to Sharzhad and helped a young girl named Amal stop militant fundamentalists from enforcing a gender apartheid.

[23] During Monsters Unleashed storyline, the Champions crossed paths with the Freelancers, a group of teenage mercenaries, who were at the time working for Roxxon to silence protesters.

[31] Hulk, Viv, and Spider-Man eventually joined the Underground where they associated with Ironheart (Riri Williams), Wasp (Nadia van Dyne), Falcon (Joaquin Torres), and Patriot (Rayshaun Lucas)[32] After Hydra leveled Las Vegas, Black Widow set out to assassinate Captain America.

Spider-Man joined her, having decided to stop running away from his supposed destiny to kill Captain America, as prophesied by the Inhuman precog Ulysses Cain.

[36] A short time following Hydra's fall, the Champions saw themselves forced into an uneasy alliance with the Avengers[37][38] to stop the High Evolutionary from causing a collision between the Earth and his Counter-Earth.

Riri, after her run in with Thanos, revealed her Mk 3 Armor, with a new design and color scheme; however, now depowered, Sam couldn't feel anything but rage at everything and is depressed.

The Champions were scattered and transformed, though only Ironheart retained the memories of her past life due to her traumatic experience when fighting Thanos, and managed to reunite the team.

[52] Champions started operating globally after giving full membership to Falcon, Patriot, The Locust (Fernanda Rodriguez), Bombshell (Lana Baumgartner), Pinpoint (Qureshi Gupta) and Power Man (Victor Alvarez).

Miles accepted Mephisto's offer and the demon reversed time resurrecting their dead teammates but unwittingly allowing a girl he saved previously die.

[60] Meanwhile, Sam and Kaldera found Commander Scott Adsit and learned the helmet had been stolen by the Thieves Guild of New York and returned to Earth.

[61] Being held by Mephisto, Blackheart became privy to his father's latest scheme and begun corrupting members of the Champions, starting with Ironheart, who had been pushing away Viv due to the synthezoid apparently having feelings for her.

[14] CBR highlighted that "without disclosing her true identity, Ms. Marvel rejects Kamala's Law and publicly vows to continue her superhero activities alongside the Champions regardless of her age.

Several agree to continue their double lives as usual in open defiance of the controversial law, while others believe Kamala is in the wrong and they should leave superhero activity to the adults".

[64] Over the course of the Outlawed event, the Champions take responsibility for their actions and expose that Roxxon is using their government contract to place young individuals with super abilities into brutal reeducation camps.

[16][65] While the Champions are now free to return to their crime-fighting careers, Kamala's Law is still intact while still at a minimum level, and Roxxon attempt to launch an app called "Roxx-On" to cover their dubious activities, under the direction of Miriam Blakemoore.

[68] During Roxx-On festival, the Champions secretly apprehend Fizzle group to ensure Kamala's public speech to expose Roxxon's true motive is a success.

While the Champions evacuate all nearby young civilians from a rampaging Champerones, Miriam stops André from damaging the company's reputation further and arrests him.
