Pirate, I Am Really Weak

The protagonist accidentally merged with the king from One Punch Man while traveling through One Piece. From then on, King embarked on a life of pretentiousness without strength. King: Weak, weak, weak, I am really one of the weak ones. Akainu: Damn the Imperial Engine, I can't even raise the will to fight. Sengoku: This guy... Is definitely a big trouble. Whitebeard: Kukuku, kid, are you also a strong person? Garp: I can rest assured that this kid is with my grandson. Newcomers are on the road, please give it a gentle thumbs up.
