A great fanfiction concept is a crossover where the villains from One Punch Man and Mob Psycho team up. It would be a huge threat, and then the heroes from both series would have to combine their efforts. In this kind of fanfiction, we could see some epic battles and unique character interactions.
I really like 'Psychic Punch'. In this fanfiction, Mob's psychic powers and Saitama's physical strength are pitted against a common enemy. The writer does an excellent job of showing how their different powers could work together. It also has some really cool fight scenes that are exciting to read.
Hard to say. Maybe it will if there's enough demand and the story has more to tell. But sometimes, even popular mangas come to an end. We'll just have to wait and see.
Mob Psycho manga has indeed finished. It wrapped up with a satisfying conclusion for fans. The author completed the narrative and tied up all the loose ends.
