Deku's One For All power could be seen as a sort of super - strong magic in the Fairy Tail universe. It could be that he has to learn to control it in a different way, like using the Fairy Tail guild's training methods. Maybe he'd have to combine it with some form of Fairy Tail magic to make it even more powerful.
If Deku had a quirk in fanfiction, it would likely impact his character development. He might have become more powerful quicker or taken on different enemies. The story could become much more action-packed or focus on different themes.
It could make for a really exciting and unique story. Deku's growth and challenges would be measured in a more structured way, adding a new layer of excitement to his journey.
Yes, there might be. The world of fanfiction is vast, and with the popularity of both Naruto and Kaido from different fictional universes, it's not unlikely that someone has created a crossover fanfiction where Naruto has some sort of connection to Kaido. You can search on popular fanfiction websites to find out.
Perhaps it's a story where Naruto is reincarnated as Kaido. He wakes up in the One Piece world with no memory of his previous life as Naruto. As he starts to regain his old memories, he tries to use his Naruto - like skills and values to change the way Kaido behaves in the One Piece universe. It could be about him trying to make Kaido a more heroic figure instead of a villain.
It could be about creating a fictional story centered around Kaido's grandson in an original character (OC) context. Maybe it involves adventures, relationships, or battles in the world related to Kaido's universe.
There's a fanfiction where Kaido is portrayed as a mentor. In this story, he imparts his knowledge and power to a young protégé. It's an interesting take as it shows a different side of Kaido. Then there's the fanfiction that focuses on Kaido's battles from the perspective of his enemies. This gives a fresh look at his combat abilities. Also, some fanfictions explore Kaido's relationships with other characters in the One Piece universe in more depth.
If Batman had Superman powers in fanfiction, he would be an unstoppable force. He could use his detective skills combined with super strength, flight, and heat vision. Gotham would be a much safer place as he could quickly stop crimes across the city without relying on his gadgets as much. He might even be able to take on more global threats, which would be a huge change from his normal focus on Gotham's underworld.
