In a fanfiction like this, there could be some interesting alliances. Eren from Attack on Titan, with his Titan - shifting ability, could team up with Deku. Deku could learn a lot from Eren's willpower and determination. Also, the quirks in My Hero Academia might be used to develop new strategies against the Titans. Like Todoroki could freeze the Titans' legs to stop them from moving.
One possibility is that the two groups initially misunderstand each other. The Survey Corps might see the heroes as some sort of strange new threat. The heroes, on the other hand, might think the Titans are just some really big and tough villains. But as the story progresses, they could start to understand each other's situations and work together. The My Hero Academia characters could introduce new technology or fighting styles to the Attack on Titan world, and vice versa.
If we consider strategy and intelligence along with power, Levi from Attack on Titan could be a top contender. His incredible combat skills and quick thinking could make him a force to be reckoned with even among the superpowered heroes. But then there are heroes like Eraserhead who can nullify quirks, which could be a huge advantage against some of the more dangerous Attack on Titan characters.
Well, All Might is also a very strong character from My Hero Academia. His sheer power and experience could make him a tough opponent for any demon slayer. However, the upper - rank demons in Demon Slayer have their own unique and terrifying abilities. For instance, Kokushibo with his sword skills and multiple eyes. In a one - on - one battle, it would be a close call between them depending on how the fight unfolds.
Well, Deku would probably be super excited to learn new kinds of magic at Hogwarts. He might struggle a bit at first with the different system compared to his quirk training, but his determination would make him study hard. Bakugo would likely be a bit of a troublemaker, challenging the wizarding rules and maybe getting into some minor duels with other students. Ochaco would be making friends left and right and might use her zero - gravity quirk in some creative ways during flying lessons on brooms.
They might be quite confused at first. Since the two universes have different rules regarding powers and the overall setting. But then they could start to see the similarities too. Characters like Bakugo might scoff at some of the ideas in the Naruto fanfiction, but secretly be intrigued. And the more intelligent characters like Momo could analyze the strategic elements in the fanfiction and think about how they could be adapted to their own battles in My Hero Academia.
Some of them could be confused. The settings and concepts in Spider - Man fanfiction might not align with what they know. Bakugo might scoff at first, thinking Spider - Man's powers are not as 'powerful' as his own explosion quirk. But as he reads more, he might start to respect the different ways Spider - Man uses his abilities to fight crime.
They might be shocked. Some fanfictions can be really out - there with different interpretations of their personalities and relationships. For example, a character used to being seen as a hero might be surprised to see themselves portrayed as a villain in some fanfictions.
One great place to find My Hero Academia and Attack on Titan fanfiction is Archive of Our Own (AO3). It has a vast collection sorted by various tags like character pairings, genres, and ratings. Another option is Fanfiction.net. There are also some Reddit communities dedicated to fanfiction where users share and discuss their favorite works.
One common crossover idea is a scenario where the Titans from Attack on Titan are considered as 'villains' in the My Hero Academia universe, and the heroes have to come up with strategies to defeat them. It could also be interesting to see how the Quirks in My Hero Academia would be perceived in the world of Attack on Titan. Maybe some characters would be seen as 'demons' because of their unique powers. And then there's the idea of a character from Attack on Titan, like Eren, somehow getting a Quirk in the My Hero Academia world and how that would change his character arc.
They might be really surprised. The world of One Punch Man is very different from My Hero Academia. For example, Saitama's extreme power would be a shock to them. Deku might be inspired by Saitama's simple way of being a hero, just doing it for the love of it, not for fame. Bakugo might think Saitama is a weakling at first because he doesn't look that impressive, but then be amazed by his power.
Well, he would probably be the most overpowered character. He could easily defeat any villain with a single punch. His presence would disrupt the power balance in the My Hero Academia world. For example, the hero rankings would be completely shaken up as he'd outperform everyone effortlessly.
