One Punch Man Manga Chapter 137

Previously sidelined, Bang, Bomb, and Fubuki arrive on the surface to join the S-Class heroes. When Atomic Samurai questions their presence, tensions ease after explanations and Bang’s conciliatory stance. Fubuki urgently pleads for help as her sister Tatsumaki collapses from exhaustion.

Guarded by Genos and Drive Knight, Tatsumaki recalls her traumatic childhood imprisonment during a lab disaster, where she was rescued by Blast, whose intervention awakened her resolve to use her psychic power to protect others. Reinvigorated by the memory, she returns to the battlefield.

Meanwhile, Drive Knight chases Psykos into a tunnel but is repelled by her attacks. Tatsumaki erects psychic barriers to contain the escaping esper, yet Psykos slips away—only to be intercepted mid-flight when Genos and Drive Knight leap onto her escaping jet, preparing a decisive finishing strike.
