I really like 'The Crossover Convergence'. It has an interesting premise where some of the Fairy Tail guild members end up in the My Hero Academia world. The author does a good job of showing how the Fairy Tail characters adapt to the new rules and powers in that world. It also has some great fight scenes that blend the different fighting styles of both franchises.
There's also 'Quirks and Magic: A New Alliance'. In this fanfiction, the heroes from My Hero Academia are brought to the Fairy Tail world. It explores how they would handle the magic there and how their quirks would interact with the magic. It's a really fun read as it delves into the cultural differences between the two worlds as well.
I really liked 'Jirou's Hidden Talent' fanfiction. In this story, Jirou discovers a hidden aspect of her quirk that she never knew before. It delves deep into her character, exploring her insecurities and how she overcomes them with the newfound power. It also has some great interactions with other characters from My Hero Academia.
Another good one is 'Nezu and the Unexpected Visitor'. In this story, Nezu has to deal with a mysterious visitor who seems to know a lot about his past. The way Nezu handles the situation shows his calmness and wisdom. It's full of suspense and keeps you hooked from start to finish.
The crossovers where the characters form teams are quite popular too. Imagine Deku from My Hero Academia teaming up with Natsu from Fairy Tail. Their different personalities and power levels create a lot of exciting storylines. Fans love to see how they would communicate and fight together against common enemies.
One popular theme is the power exchange. For example, characters from My Hero Academia getting magic from Fairy Tail or vice versa. It's interesting to see how they would use the new powers. Another theme is the character crossovers, like Natsu from Fairy Tail teaming up with Deku from My Hero Academia. They have different personalities and abilities, so it creates a lot of engaging storylines.
One good Ochako jealous fanfiction is 'Green-Eyed Uravity'. In this story, Ochako gets jealous when Deku spends a lot of time with a new female hero in training. It really delves into her feelings of insecurity and how she tries to deal with them. The author does a great job of portraying Ochako's character.
One great Nejire Hado fanfiction is 'Nejire's Ascent'. It focuses on Nejire's training journey and how she overcomes her self - doubts. Another one is 'Nejire and the Lost Quirk'. In this story, Nejire discovers a mysterious quirk and tries to figure out its origin. And there's also 'Nejire in the Parallel World' which takes Nejire to a different dimension and shows how she adapts to new challenges there.
A really interesting one is 'Bakugou's Sister: The Forgotten Hero'. This fanfiction takes a darker turn. The sister has been overshadowed by Bakugou all her life. But when a great danger befalls their city, she steps up in ways no one expected. It's a story about self - discovery and proving oneself despite being in the shadow of a more popular family member.
One great 'My Hero Academia' quirkless badass fanfiction is 'The Quirkless Prodigy'. In this story, the main character uses their intelligence, martial arts skills, and sheer determination to rival the quirk - having heroes. It's really inspiring to see how they overcome the odds in a world that seems to be all about quirks.
A more light - hearted one is 'My Hero Academia: A Peaceful Camping Trip'. It focuses on the students simply enjoying the camping experience, having friendly competitions, and sharing stories around the campfire. It's a feel - good fanfiction that shows the more laid - back side of the characters.
One interesting My Hero Academia zombie fanfiction is 'Heroes in a Dead World'. It shows how the heroes have to use their quirks in a whole new way against zombie hordes. The character development is really engaging as they struggle to survive and protect the remaining civilians.
