Unlicensed Knight gained the Explosion-Explosion Fruit and became the focus of people seeking Devil Fruits, while the Hero Association summoned all S-Class Heroes after the prophet Shibabawa foresaw Earth's destruction within half a year. Allen and Tatsumaki headed to headquarters after Tatsumaki defeated the Ancient King, and Allen revealed that the predicted disaster was classified as God.

• Unlicensed Knight ate the Explosion-Explosion Fruit, accidentally detonated part of a restaurant, and accepted Allen as his teacher.

Allen and Tatsumaki arrived at Hero Association headquarters for an emergency S-Class meeting, where Allen’s private feud with Atomic Samurai erupted into a one-sided fight.

After questioning the suspicious death of prophet Shiababawa and her final warning that the Earth was doomed, Allen accused the Hero Association of hiding the truth and proposed that the S-Class Heroes form a new Justice Alliance. As tremors shook headquarters, Allen recognized the arrival of Boros’s spaceship, blasted open the wall, and flew off to seize it.

After Allen defeated Boros, he prepared to refit Boros’s spaceship and gain energy-absorbing cells so he could plunder resources across the universe. Sakura asked to join the mission to find her own path, while Psykos reconsidered the Monster Association’s plans after seeing footage of Allen and Boros’s power.

• Allen underwent a cellular modification based on Boros’s traits and agreed to let Sakura join his planned energy-gathering mission.
• Psykos watched footage of Allen and Boros’s battle and began doubting whether the Monster Association should continue with its original plan.

After Boros’s attack convinced the world that Earth might soon be destroyed, Allen agreed to provide 15,000 people with passage aboard the missing spaceship so they could preserve human civilization. Meanwhile, the Hero Association faced mass defections and financial collapse, and its executives debated how to survive the scandal.

• Governments and wealthy supporters backed Artoria’s new Justice Alliance as the Hero Association lost donors, executives, and heroes after Allen’s departure and the exposure of corruption.
• At Reizel’s banquet, he asked Allen whether he possessed Boros’s spaceship and explained the plan to evacuate talented people before Shiababawa’s predicted destruction of Earth.
• Allen promised Reizel 15,000 places and told him the spaceship would stop outside Z-City’s uninhabited zone in ten days so they could prepare knowledge and supplies.
• After Allen left, the banquet guests crowded around Reizel and clamored for places aboard the spaceship for themselves and their families.
• At the Hero Association headquarters, executives proposed apologizing, cutting ties with corrupt staff, opening the books, and cooperating with the Justice Alliance, while one executive threatened to silence those under investigation.

Artoria’s new Hero Organization established its headquarters and trained a growing force as Child Emperor warned that the Hero Association’s leaders might target them. Before the organization’s first general assembly, Allen cautioned Artoria that a major battle was approaching, and she vowed to show the world what a true hero was.

Allen and Sakura tested the Ten-Tails Divine Tree on an alien planet, draining it completely before setting out to find another world. On Earth, Fubuki ignored Tatsumaki’s warning and led the Blizzard Group to confront Unlicensed Knight, prompting Child Emperor to race to stop a potentially disastrous clash.

• The Alliance held its first general assembly, where heroes voted equally to establish its rules, code of action, and benefits.

• Fubuki ignored Tatsumaki and left with her subordinates, so Tatsumaki warned Child Emperor that her sister was heading to cause trouble.
• Child Emperor tracked the Blizzard Group and discovered that Fubuki was targeting Unlicensed Knight, then flew toward the confrontation to prevent a wider conflict.

Fubuki confronted Unlicensed Knight, but Artoria and Child Emperor intervened and defeated her and Tatsumaki after condemning the Blizzard Group’s bullying. The sisters were left in the Alliance’s custody, while footage of Tatsumaki’s defeat and accounts of Fubuki’s abuse spread widely and fueled public debate about the Hero Association.

After settling more than fourteen thousand immigrants on a new planet, Allen and Sakura searched for a suitable Neutron Star so he could forge powerful weapons from its matter.

• Following Boros's star map, Allen and Sakura drained energy from planets and extinguished stars until a crew member found a suitable Neutron Star twelve light-years away.

Allen returned to Earth after two months away and told Saitama and Genos that heroes and monsters shared the same basis in gene mutation, with will and beliefs shaping the difference.

Allen treated Garou’s fight with Watchdog Man as a chance to direct him toward stronger opponents, then brought him to the Super Fight to face Water Dragon. As the Monster Association’s attack began, Garou copied Water Dragon’s signature technique and struck him down, while Bang and Bomb searched for Garou elsewhere.

• Watchdog Man brutally defeated Garou in Q-City, and Allen healed him before advising him to train against opponents closer to his level.
