One Punch Man Manga Chapter 55

Metal Bat battles Senior Centipede and Rafflesidon, overcoming Rafflesidon’s disorienting gas by self-inflicting pain to regain control. He defeats both monsters with decisive strikes. When B/C-Class heroes Pineapple and Mohawk arrive, Metal Bat tasks them with evacuating the sponsor and his son, eager to aid his sister. However, Dragon-level Elder Centipede surfaces, forcing Metal Bat to confront it alone as the others flee.
