You can try Archive of Our Own (AO3). It has a large collection of fanfics from various fandoms, including 'Mob Psycho 100 x One Punch Man'. The tagging system there makes it easy to search for the specific crossovers you're interested in.

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.

First, you need to understand the characters well. Know their personalities, their powers, and what makes them unique. For example, Mob's emotional state affects his psychic powers, and Saitama is always looking for a worthy opponent. This knowledge will help you write them accurately.

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.

One idea could be that Mob and Saitama accidentally switch powers for a day. Mob would be super strong but struggle with his usual self - control, while Saitama would have to deal with Mob's psychic powers which he has no experience with.

The unique powers of the characters. Saitama's one - punch strength and Mob's psychic powers are very different yet equally fascinating. Writers can create all kinds of scenarios with these powers interacting.

Definitely Mob and Saitama. Their personalities are so different. Mob is a shy and emotional high - school boy with powerful psychic abilities, while Saitama is a bored and seemingly emotionless hero who can defeat any enemy with one punch. Their interactions would be full of comical misunderstandings and also opportunities for character growth.

A great plot would be if the two universes somehow merged, and Mob and Saitama had to deal with the chaos. Mob might be freaking out about all the new strange things he's seeing, while Saitama is just casually walking around looking for some cheap groceries. Then they get pulled into a fight against a group of villains who are causing mayhem in the newly merged world. They learn to combine their skills and defeat the villains, and in the process, Mob learns a thing or two about being confident from Saitama.

Teruki Hanazawa from Mob Psycho 100 could be really interesting in a crossover. He might initially see Saitama as a rival, thinking that his strength is just another form of power that he can compete with. But as he gets to know Saitama better, he realizes that Saitama's power is on a whole different level. Saitama, in turn, would probably just be like 'oh, another guy with powers' and not be too fazed. And when it comes to characters like Genos from One Punch Man, he might be very curious about Mob's psychic abilities and try to analyze them scientifically.

I really liked 'A Different Kind of Hero'. In this fanfic, it delves deep into how the concepts of power and heroism from both series interact. The author does a great job of bringing together the characters from both shows. For example, Shigeo Kageyama's calm and collected nature contrasts well with some of the more brash characters in My Hero Academia, creating some really engaging character dynamics.
