Another aspect to consider is how the Super Saiyan transformation would affect the relationships in the Naruto world. If Sasuke were to gain Super Saiyan powers, it could either drive him further away from Naruto due to the newfound power or bring them closer as they explore the new abilities together. Also, the concept of ki from Dragon Ball and chakra in Naruto could be merged, creating a whole new type of energy for the characters to utilize.
Perhaps in the fanfiction, a lava dragon slayer is accidentally transported to the Naruto world. The slayer could team up with Naruto and his friends. They would share their knowledge of lava - based attacks and the slayer could learn about chakra. Together, they could go on adventures, facing off against powerful villains. The slayer could use their unique abilities to help in battles, like melting through strong defenses or creating lava - based barriers.
Another possibility is a corrupted dragon spirit that has been awakened due to the mixing of the two worlds. This spirit could be spreading chaos and trying to destroy both the ninja world and the dragon world. Naruto would have to figure out a way to stop it, as it has powers that are beyond what he has faced before.
One interesting concept could be Naruto having dragon - like powers. For example, he might be able to breathe fire or fly like a dragon. Another concept could be the merging of Naruto's world with a dragon - based world, leading to new cultures and power systems. Also, Naruto might form unique bonds with dragons, similar to how he bonds with his friends in the original series.
A third common theme is the exploration of new worlds. Naruto is taken to the Blue Dragon world or vice versa. This allows the author to describe new landscapes, creatures, and magic systems. It gives readers a sense of adventure as they explore these new and unfamiliar settings along with the characters.
In a Naruto - Fairy Tail fanfiction with a Water Dragon Slayer, one idea could be that the slayer is from a hidden village that has some connection to Fairy Tail's world. The slayer's abilities would be quite useful in Naruto's world. They could use their water dragon slaying magic to fight against the Akatsuki, for instance. Their magic could be a great asset in battles, especially in areas where there is a lot of water or moisture. It would be cool to see how the Naruto characters react to this new type of power.
In fanfiction, sure. Fanfic writers love to mix and match different universes. Naruto's world is full of ninjas, chakra, and complex village politics, while Bulma's world in Dragon Ball has Saiyans, powerful energy blasts, and advanced technology. For them to get married in a fanfic, the writer would have to find a way to bridge these two very different worlds. It could be a fun and interesting read as the writer tries to combine Naruto's ninja skills with Bulma's scientific knowledge in their relationship.
It could be Orochimaru. He might have heard about the unique magic in Dragon Academy and wants to use it for his own evil purposes. He could try to corrupt the magic there and use it to enhance his jutsu or gain immortality in a new way.
One possible plot could be that Naruto is somehow transported to the Dragon Academy world. He could use his ninja skills to adapt and make new friends. Maybe he'd teach the students at Dragon Academy some of his jutsu, like the Shadow Clone Jutsu, which could be useful in their own magical battles.
