One Punch Man Manga Online Chapter 55

Chapter 55 titled Pumped Up shifts focus to the hero Metal Bat, who is assigned to guard a high-ranking Hero Association sponsor, Narinki, and his son, Waganma. Their meeting takes place near a construction site, but things quickly spiral out of control when two powerful Demon-level monsters—Rafflesidon, a reptilian beast with venomous gas attacks, and Senior Centipede, a massive armored insect—launch a surprise attack. Metal Bat jumps into action, showing off his raw strength and endurance as he fends off both monsters. Rafflesidon tries to incapacitate him using a hallucinogenic gas, but Metal Bat, refusing to fall, smashes himself in the head with his own weapon to regain focus and break free of its effects.

Driven by his unbreakable fighting spirit, Metal Bat turns the tide, landing powerful blows and taking down the monsters with sheer force and determination. Just when it seems the worst is over, a new and far more terrifying threat appears—Elder Centipede, a massive Dragon-level monster known for having destroyed entire cities. As the ground shakes from its arrival, Metal Bat prepares himself for the next, even more dangerous fight, refusing to back down.
