Throughout most of the One-Punch Man series, Genos has openly pursued his mission of revenge. As he explained when he first met Saitama, a Mad Cyborg attacked his town when he was just 15 years old. Since then, he has been on a journey to become strong enough to defeat that cyborg.
During this time, Genos has relied heavily on his benefactor, Dr. Kuseno, who not only saved him but also transformed him into a powerful cyborg to help fulfill his desire for revenge. That’s why the latest One-Punch Man webcomic chapter delivers a shocking revelation: Dr. Kuseno is not the savior everyone believed, but the mastermind behind Genos’ tragic past.
One-Punch Man Reveals the True Mastermind Behind Genos’ Tragic Past

Although the One-Punch Man manga debuted in 2012, the original webcomic by creator ONE started releasing chapters in 2009. That means over 15 years have passed since the series first revealed Genos’ origin story.
Fans long believed Genos’ town was attacked by a violent cyborg and that Dr. Kuseno was his rescuer. However, the latest developments in chapter 156 of the webcomic reveal that Dr. Kuseno is actually the one behind Genos’ tragic past.
When Genos accuses Bofoi (Metal Knight) of creating the Mad Cyborg that attacked his town, Bofoi counters by claiming that what Genos remembers are false memories implanted by Dr. Kuseno. Bofoi even states that both Genos and Drive Knight are pawns in Dr. Kuseno’s plan to conquer the world.
Chapter 156 Hints at a Seven-Year-Long Conspiracy
As expected, even if Bofoi’s words are true, Genos struggles to accept them, especially since he believes Bofoi killed Dr. Kuseno the night before by sending an assassin. However, Bofoi insists that Dr. Kuseno never actually died and is staging a ruse to awaken Genos’ willpower.
The most shocking part is yet to come. Just as Bofoi mentions that Dr. Kuseno might still be alive, the webcomic zooms in on Genos’ earring, implying that the doctor could be listening to their conversation through that device at that very moment.

This twist is especially stunning because a fan once asked creator ONE about this earring back in 2018. At the time, ONE only said the earring had a purpose but kept it a secret. Seven years later, the webcomic finally reveals the truth.
While fans now have a clearer understanding of Genos’ true past, these revelations have plunged him into deeper anguish than ever. Hopefully, upcoming chapters will show Saitama or someone else helping this S-Class hero find his way back to reality.
