A really cool fanfiction idea would be Obito being reborn in the My Hero Academia universe. He is born with a quirk that is a manifestation of his past life's abilities. He then tries to make up for his past mistakes in the Naruto world by becoming a great hero in MHA. He could have a rivalry with some of the top heroes who initially doubt his motives, but as he proves himself, they come to respect him.
There could be a fanfiction where Obito has to adapt to the hero society in My Hero Academia. He starts as an outcast because of his different abilities and his past. But as he shows his determination to do good, he slowly gains the trust of the heroes. He might even develop a new quirk - like a combination of his Sharingan powers and the energy in the MHA world. And he could end up being a mentor figure to some of the younger heroes in training.
Deku would be a great character to pair with Obito. Deku's pure - hearted nature and his drive to be a hero could contrast with Obito's more complex and troubled past. Obito could see in Deku the kind of hero he once wanted to be, and he could help Deku in ways that All Might or other heroes couldn't, especially when it comes to dealing with darker aspects of the hero world.
One interesting 'My Hero Academia Izuocha fanfiction' could be about Ochaco helping Izuku train in a unique way that unlocks a new quirk aspect. Maybe she uses her zero - gravity power to create a special training environment where Izuku can practice his movements in a gravity - defying manner.
There are many great ones. For Naruto fanfiction, some might focus on alternate endings like Naruto becoming a different kind of Hokage. In My Hero Academia fanfiction, you could find stories about a student with a unique quirk that wasn't in the original. When it comes to crossovers between Naruto and My Hero Academia in fanfiction, it could be about how the characters from Naruto would interact with those in My Hero Academia, like Naruto trying to understand the concept of quirks.
One interesting story could be about a gamer who gets sucked into the My Hero Academia world and uses their gaming skills to level up their quirk faster than anyone else. They might start as an underdog but quickly rise in the hero ranks.
One interesting 'eri my hero academia fanfiction' could be about Eri learning to control her quirk in new and unexpected ways. For example, she might start to use it not just for healing but also for defensive purposes, like creating shields made of her horn fragments. Another could be a story where Eri forms a special bond with one of the other students at UA, perhaps someone like Deku, and they train together to help her gain more confidence in her abilities.
A great fanfiction idea might be a crossover where characters from Naruto with Sharingan abilities are brought into the My Hero Academia world. They could teach the My Hero Academia characters about the power of the Sharingan and how to use it, leading to some really cool team - up battles and training sessions.
Some TG fanfictions could focus on side characters. For instance, Mineta Minoru could be transformed into a female character in a story. This would completely change his interactions with other characters, especially with the female students. It could also be a story about how he overcomes the challenges and prejudices that come with the new identity in the hero school environment.
In some 'My Hero Academia dragon fanfiction', the dragon aspect could be related to a secret society. A hero discovers this society that has been using dragon - related powers for their own purposes, either good or bad. This could lead to a conflict where the hero has to decide whether to join them, expose them, or try to change their ways.
One interesting Tamaki fanfiction could be about his training journey in more detail. It might show his struggles and how he overcomes them with his unique quirk. Another could be a story that focuses on his relationships within the school, like his friendship with Mirio and how they support each other.

Another could be a story where he forms an unlikely alliance with a hero to achieve a common goal. There are also fanfictions that might explore his relationship with other members of the League in a more in - depth way.
