What are some interesting OPM (One Punch Man) meets Attack on Titan fanfictions?

One interesting twist could be that a Titan eats a character from One Punch Man and gains not only their physical abilities but also their memories. This Titan then starts to have an identity crisis and tries to rebel against the other Titans. It could lead to a situation where the heroes have to decide whether to kill this unique Titan or try to use it to their advantage.

Another concept could be a crossover where some of the Titans gain the power of One Punch Man's enemies. For example, a Colossal Titan-like being that has the regenerative abilities of some of the monsters Saitama has fought. The heroes from both universes would then have to team up to defeat this new threat. They would learn from each other's fighting styles and strategies.

In a fanfiction of these two, the powers could be combined in a different way. For example, the Titans could have some of the characteristics of the monsters in 'One Punch Man'. They could be even more powerful and unpredictable. Meanwhile, the heroes from both universes could team up. Mikasa could learn some fighting techniques from Saitama, and Genos could be fascinated by the technology in the 'Attack on Titan' world. This would create a complex and exciting story with a lot of potential for character development and epic battles.

One interesting 'One Punch Man King' fanfiction could be where King actually has some hidden powers that he's been suppressing. In this fanfic, he might start to slowly reveal his true strength during a really tough battle against a new and extremely powerful monster. It could be a story that focuses on his internal struggle between wanting to keep his low - key image and having to step up to protect the city.

Well, it could be about Saitama somehow ending up in the world of Attack on Titan. Maybe he's there to help the Scouts fight the Titans. He'd probably just one - punch all the Titans and make it seem like a really easy job, while the Scouts are left in awe of his power.

I think Eren and Saitama would also be a great pair. Eren has his complex motives and the power of the Titans, and Saitama is so simple - minded yet incredibly strong. They could interact in a really unique way, like Eren being all fired up to fight Titans and Saitama just being like 'Oh, that's nice' and then one - punching all the Titans. It would be a contrast of personalities and powers.

In some fanfictions, Garou spares One Punch Man and then teams up with him temporarily to fight a greater evil. This unexpected alliance showcases their combined strength and also explores the dynamic between a self - proclaimed villain and an uninterested hero.

It could blend the two universes by having the characters interact. For instance, Levi Ackerman could meet Saitama. Levi would be impressed by Saitama's strength, but also notice his carefree attitude. Saitama, on the other hand, would be intrigued by Levi's skills. They could then team up to fight a common enemy, like a super - powerful Titan - like monster that is a threat to both of their worlds. This would bring out the best in both characters and create a unique dynamic.

One great One Punch Man fanfiction is 'The Saitama Chronicles'. It delves deeper into Saitama's daily life and his inner thoughts. Another interesting one is 'Genos' Redemption', which focuses on Genos' growth and his relationship with Saitama in a unique way. And 'The Monster Invasion' fanfiction presents a more intense and complex scenario of monster attacks in the One Punch Man universe.

One interesting storyline could be where the fanfiction explores an alternate universe where the Titans have a different origin. Maybe they are not just mindless giants but are actually the result of a failed scientific experiment gone wrong in a more complex way than in the original series.
