One punch man:Traveling between worlds

This story is about a simple otaku who has above-normal physical powers and psychic powers who doesn't use these abilities for anything, except for basic things. This is our protagonist who lives in a time of peace. Being the son of two heroes, he doesn't have much to do other than read manga or watch anime since his parents are already stronger themselves, not letting their son have the opportunity to be a hero. But what would happen if this boy traveled to the worlds he reads about and sees every day? And that's what we're going to find out.
