Chapter Summaries

Vegapunk found and captured the Sky Race on a hidden Floating Island, then froze its Flesh Hive and brought it to the House of Evolution. He fed the Sky King and the Skyfolk Flesh Hive to a modified Nest Heart, strengthening the embryo inside it.

Saitama brought a massive cicada to Vegapunk’s laboratory, where Vegapunk planned to use it to nourish his growing monster embryo, then headed underground to clear monsters so he could get internet access for a game machine. Meanwhile, Orochi sensed the rival embryo and grew agitated, while Vegapunk learned of Shibabawa’s prophecy and realized Boros might arrive while Saitama was out of reach.

Saitama and Boros fought while an energy blast opened the Monster Association beneath Z-City, bringing its Monsters into battle with Boros’s Dark Matter Thieves.

After becoming an S-Class Hero and receiving a new home, Saitama returned to Vegapunk’s House of Evolution for its hot pot and to see the completed Super Monster. Vegapunk showed the group his powerful, controlled clone, and Tatsumaki entered an extraordinary Testing Ground, where she was immediately crushed by its gravity.

• The others entered the Testing Ground and saw an earth-yellow landscape beneath an Energy Shield, with violent winds and the cosmic starry sky beyond it.

Vegapunk then urged Saitama to demonstrate his strength, leaving him eager to try his Serious Series without worrying about destroying Earth.

• Fubuki gave Tatsumaki an oxygen-producing pill after Tatsumaki struggled with the planet’s atmosphere, and Vegapunk explained that he had connected the planet to the laboratory through a Wormhole Portal.

• Vegapunk and the others returned to the House of Evolution after Saitama’s battle, and Vegapunk suggested Saitama push a planet to replace the destroyed testing ground.
• Tatsumaki admitted that she wanted to learn Chakra after realizing that her strength had limits and Vegapunk’s Super Monster and Saitama surpassed her.
• Vegapunk helped Tatsumaki absorb a Chakra Seed, and she needed time to nurture the power because her body was frail compared with her mental strength.

Vegapunk transformed the Phoenix Plush Suit into the Phoenix Armor, gaining powerful defensive and restorative equipment with possible death-defying properties. With the Space Gate complete, he prepared to return to the Pirate World with Saitama, Tatsumaki, Fubuki, Child Emperor, Psykos, and others.

• Vegapunk converted the Phoenix Plush Suit’s energy into his Meteor Armor, creating the crimson-gold Phoenix Armor.

After surveying the robot factories on the Red Line, he joined Dragon and the Revolutionary Army in assembling a force for the assault.

Vegapunk visited Fish-Man Island, where Neptune hoped to ask him for help repairing the island’s environment after Hancock’s attack. A fish-man rebellion broke out over Neptune welcoming the people blamed for the island’s destruction, and Vegapunk prepared to leave rather than risk a confrontation.

• Vegapunk arrived at Fish-Man Island and saw the damage to the island and the dimmed roots of Sunlight Tree Eve caused by Hancock’s Shinra Tensei.
