Naruto Crossover One Punch Man Fanfic: What Are Some Interesting Plot Ideas?

One idea could be a crossover with Dragon Ball. Saitama could participate in the World Martial Arts Tournament and effortlessly defeat all the opponents, creating a hilarious situation. His nonchalant attitude would contrast sharply with the intense and competitive nature of the Dragon Ball characters.

Well, perhaps a plot where Genos follows Saitama into the My Hero Academia world. Genos could enroll in UA as well and show off his advanced technology - based powers. He might get into a competition with Bakugo over who is more powerful. Meanwhile, Saitama is just casually wandering around, accidentally solving problems and leaving the students and heroes in awe of his effortless strength.

One idea could be that Naruto and Saitama team up to fight an otherworldly threat that neither could handle alone. Maybe a villain from Naruto's world combines some of Orochimaru's jutsu with the power of the Dark Matter Thieves from One Punch Man. Another plot could be a friendly competition between Naruto and Saitama to see who can complete a series of challenges faster, like saving a village or defeating a group of strong foes.

Perhaps there could be a villain in the crossover fanfiction that is a threat to both worlds. Saitama and Ainz have to team up to defeat it. Saitama is used to soloing enemies, and Ainz is used to having his minions do the work. So, they have to overcome their differences in fighting styles and learn to work together. Ainz might be in awe of Saitama's sheer strength, and Saitama might be a bit weirded out by the undead nature of Ainz and his minions.

Another plot could involve a crossover with a different anime universe through a strange portal. For example, if he entered the world of My Hero Academia. Garou could initially try to assert his dominance but quickly realizes that the quirks in that world are different from his martial arts skills. He might then start to learn about these new powers and how to adapt, all while causing chaos and also forming unexpected alliances.

Another idea is that Naruto, curious about other powerful beings, uses a jutsu to travel to the One Punch Man universe. There, he would be amazed by Saitama's strength. Naruto could try to learn from Saitama how to be so effortlessly strong, but Saitama would probably just shrug it off and say there's no special trick. They could team up to fight some of the monsters in Saitama's world, with Naruto using his ninjutsu and Saitama just punching things away.

A crossover with 'Dragon Ball' would be cool. Picture Saitama facing off against Goku. It would be an interesting contrast between Goku's love for a good fight and Saitama's boredom with opponents who can't challenge him.

How about a crossover with 'Attack on Titan'? Saitama could find himself in the world of the Titans. His ability to defeat any enemy with one punch would be extremely useful against the Titans. He might not understand the complex politics and fear that surrounds the people in that world at first. But as he starts taking down Titans left and right, he would become a sort of legend among the survivors.

One idea could be exploring the backstory of Saitama's training in more detail. Maybe he had some secret mentors or faced unique challenges during his intense training regime that made him so powerful.

One idea could be that Naruto somehow gets transported to the One Punch Man universe. He teams up with Saitama to fight a common enemy that has the ability to absorb chakra and is also super strong physically. They start off not understanding each other's powers but gradually learn to work together.
