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.
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.
One idea could be a crossover where Naruto is transported to the One Piece world and has to face Kaido. Naruto's unique jutsu and his never - give - up attitude could create an interesting dynamic against Kaido's brute strength. Maybe Naruto tries to use his Rasengan against Kaido's tough body, and has to find new ways to adapt his skills in this new world.
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.
Well, it could be about a story where the grandson has some sort of special connection to both Kaido and Big Mom. Maybe he's caught in the middle of their power struggles or alliances. It could also explore a more family - oriented side, where they are trying to shape the grandson in their own image or for their own purposes.
In a Naruto Kaido fanfiction, to incorporate their different power systems, you could have Naruto's chakra - based jutsu interact with Kaido's Devil Fruit powers. For example, Naruto's Fire Style: Great Fireball Technique could be used against Kaido's ability to transform into a dragon. The heat from the fireball might have different effects on Kaido's dragon form compared to how it affects normal opponents in the Naruto world.
It could be about Naruto getting Cell's powers. Maybe through some strange ninja jutsu gone wrong or a magical encounter. He could then use these new powers in his ninja battles.
It could be about Naruto using his telekinetic powers to fight new and stronger enemies. Maybe he discovers this power during a difficult battle and has to quickly learn to control it to save his friends.
It could be about Naruto somehow ending up in Castiel's universe in Supernatural. Maybe he teams up with Castiel to fight demons or other supernatural threats.
Well, it might explore how Naruto's personality and actions change when he is in a state similar to being stoned. Maybe his usual energetic self becomes more laid - back and he approaches problems in a different way in the fanfiction. It could also show how his friends react to this new, altered Naruto.
I'm not sure if there is a specific 'naruto is trigon fanfiction'. But if it exists, it might be a very strange and creative crossover. Maybe in this fanfiction, the world of Naruto somehow intersects with the concept of trigon, perhaps Trigon's powers are introduced into the Naruto universe and change the way ninjas fight or interact.
