Perhaps in the fanfiction, the leviathan is a sentient being from a different dimension. Naruto forms a bond with it not just as a summon but as a friend. They communicate telepathically, and the leviathan helps Naruto understand some of the deeper secrets of chakra by showing him how it manipulates energy in its own dimension.
The leviathan could be part of a prophecy that Naruto doesn't fully understand at first. When he summons it, he discovers that the leviathan's actions will either save or destroy the ninja world, depending on what Naruto does next. This creates a high - stakes situation and a great plot twist.
Well, it depends on the specific fanfiction. There are countless Naruto fanfictions out there, and while some might depict Naruto as secretly a summon, others may not touch on this idea at all. It's all about the creativity of the fanfiction authors.
Well, there could be a 'naruto leviathan fanfiction' where the leviathan is actually a form of a powerful jutsu gone wrong. Naruto and his friends have to find a way to reverse the jutsu and stop the leviathan from wreaking havoc. It could involve a lot of teamwork and Naruto using his new - found skills to combat the beast. This type of story would be full of action and adventure as they race against time.
There might be a fanfiction where Naruto is summoned to the devil world by Serafall. In this story, Naruto could be seen as an exotic being, and he has to navigate the complex politics and power struggles in the devil world. Serafall might take Naruto under her wing, teaching him about the devil world while Naruto teaches her about his ninja way. It could be a story full of adventure and cultural exchange between two very different universes.
In some Naruto fanfictions, it's possible for Naruto to summon snakes. Fanfiction often takes creative liberties, so writers might give Naruto this ability for the sake of an interesting plot twist or a new power - up. It allows for different storylines to develop, like Naruto using snake - based jutsus or having a connection to snake - related elements in the Naruto universe that he doesn't have in the original series.
One interesting storyline could be a young ninja who discovers a rare and powerful insect summon. For example, they might find a group of glowing beetles that can create illusions. The ninja then has to learn how to control and use these beetles in battles against other powerful foes in the Naruto universe.
He could summon different kinds of tigers. Maybe there are snow tigers for cold environments. These tigers would be white - furred and well - adapted to snowy areas. They could be used in missions in the Land of Snow.
Definitely Pikachu. Since Naruto is often in need of a quick and agile ally, Pikachu's speed and electric attacks would be very useful. Plus, Pikachu's cute appearance but powerful abilities would create an interesting contrast with Naruto's ninja style.
Maybe Jiraiya. Since Jiraiya was Naruto's mentor and taught him a lot of things. He might have some knowledge about summoning kami and pass it on to Naruto.
