Maybe a story where a Tokyo Ghoul character gets transferred to the My Hero Academia universe. They could be mistaken for a villain at first because of their ghoul appearance, but then prove themselves to be an ally. For instance, Kaneki could use his kagune in unique ways during hero training exercises, impressing the teachers and students alike.
Another interesting concept is a fanfiction where the quirks from My Hero Academia are combined with the powers of the ghouls in Tokyo Ghoul. For example, a character could have a quirk that allows them to control their kagune better, or a ghoul could have a 'quirk - like' ability that is enhanced by their ghoul nature. This would create a whole new set of power dynamics and storylines.
Todoroki from My Hero Academia could be really interesting. His dual - quirk nature could have some really cool interactions with the ghoul powers. He could use his ice side to counter the heat - based attacks of some ghouls, or his fire side to fend off cold - blooded ghouls. His complex backstory could also add depth to a story set in a crossover world.
First, you need to have a good understanding of the two universes. Know the characters, their powers, and the overall themes. For Tokyo Ghoul, understand the concept of ghouls and their society. For My Hero Academia, know about the quirks and hero system. Then, come up with an interesting plot. It could be a crossover where the characters from both worlds meet, or a new story within one of the universes.
A cool concept for My Hero Academia fanfiction is to have a time - travel plot. A character could go back in time and change a significant event in the My Hero Academia world. This could lead to a completely different storyline. Or you could write a story centered around a villain redemption arc. For instance, giving a more in - depth look at how a villain like Shigaraki could potentially be redeemed and how the heroes would react to that. Additionally, fanfiction about a tournament between different hero agencies could be really exciting.
You could create an OC who is a ghoul investigator from a foreign country. This OC would bring different techniques and perspectives to the fight against ghouls. They might also face discrimination or misunderstanding within the Tokyo Ghoul universe due to being an outsider. For example, they could have a special weapon or training method that the local investigators haven't seen before.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). It has a large collection of fanfics for both Tokyo Ghoul and My Hero Academia. Many talented writers post their works there, and you can search by tags such as 'Tokyo Ghoul', 'My Hero Academia', and different genres like action, romance, etc.
One idea could be a fanfic where a human character tries to form a peaceful co - existence pact with the ghouls. They might start by secretly helping a friendly ghoul and gradually work towards getting both sides to understand each other better.
One idea could be a crossover where the heroes from My Hero Academia are transported to the Marvel universe. They could team up with the Avengers to fight a common enemy, like a powerful villain who has the ability to steal quirks and superpowers. For example, imagine Deku working alongside Spider - Man, learning new ways to use his quirk from him.
One idea could be a crossover with the Naruto universe. The characters from My Hero Academia could interact with Naruto characters. For example, Deku might learn some new fighting techniques from Naruto. Another idea is a crossover with the Harry Potter world. The students at U.A. could visit Hogwarts and experience magic, while the Hogwarts students could learn about quirks.
Well, you could focus on the social aspects in a My Hero Academia college fanfiction. Maybe some characters struggle to fit in because their quirks are considered odd or too powerful. Or perhaps there are rivalries between different departments, like the combat - focused department and the support department. You could also write about a college event, like a hero - themed sports festival, where the characters show off their quirks in new and exciting ways.
One idea could be that the Autobots and Decepticons arrive in the My Hero Academia world. The heroes could be initially confused by these giant robots with strange powers. For example, Izuku Midoriya might try to understand their technology and powers in relation to his own Quirk. He could see the Autobots' ability to transform as a super - power similar to a Quirk and try to learn from them. The villains in My Hero Academia might team up with the Decepticons for their own evil purposes, leading to epic battles between the combined forces of heroes and Autobots against the villains and Decepticons.
