One-Punch Man: Awakening a Fruit and Taking King as My Disciple

From the start, he awakened the Glint-Glint Fruit and the Tremor-Tremor Fruit, instantly killed Vaccine Man, and took King on as his disciple, giving King the power to fight monsters too. He is a hero, a king, One-Punch Man’s good friend, and someone in the Hero Association who can grant others both hope and destruction. He gave the Hero Association a chance to strike back against the monsters, and is also someone the will of the world fears. He follows his own heart, lives freely without fear, and has a sense of right and wrong. He may not have much, but he has principles he won’t abandon. My name is Xu Du. I’d rather you call me “sir” than “mister.” Say it from the heart, and show me the respect I deserve. But if you’re looking to get yourself killed, I’ll be happy to oblige. (He crosses his arms and sits on the sofa, his gaze calm and faintly amused.) P.S. This is a multiverse story, so it won’t stay in the One-Punch Man world. For now, I’m planning One-Punch Man and Naruto.
