Chapter 9: House of Evolution

Armored Gorilla recounts the origin of his master, a brilliant researcher who once gifted the world countless advances yet grew disillusioned with people. Convinced that mankind had to seize control of its own evolution, the scientist restored his youth, mastered self-replication, and built a facility devoted to that pursuit. Saitama cuts the tale short once he learns the lab covets his physique, and the two heroes resolve to march on the enemy stronghold at once.

Before departing, the gorilla transmits an alert to his creator, who reels at the loss of his experiments and orders the clones to ready their trump card. Four hours of climbing later, Saitama and Genos reach the mountaintop compound, which the cyborg flattens together with a stretch of the surrounding peaks. A concealed hatch survives the rubble, and after Saitama tears it loose the pair descends underground.

Inside, a terrified duplicate empties a firearm before a single strike detonates him. The genuine scientist then steps forward to address the caged behemoth surrounded by the corpses of his failed copies. Snapping his shackles apart, the creature proclaims himself the New Human. Presenting a photograph of the two intruders, the scientist commands him to retrieve Saitama's body by any means, alive or otherwise.
