Perhaps it's related to his connection with the Nine - Tailed Fox. In the original Naruto story, he has a strong bond with the Nine - Tailed Fox. In the fanfic, this bond could have evolved in a way that allows him to summon foxes. It could be a manifestation of the latent power within him that he finally manages to tap into and use to summon these fox - like creatures.
The ability to summon foxes might make Naruto more of a target. Villains would be interested in his new power. This could lead to more dangerous and complex storylines as Naruto has to not only protect himself but also the foxes he summons. It could also lead to new alliances as other characters see the potential of the foxes in the fight against common enemies.
The summoned foxes could make some characters more wary of Naruto. For example, if the foxes are seen as powerful and unpredictable, some ninjas might be afraid of Naruto's newfound ability. On the other hand, it could strengthen his bond with characters like Kakashi. Kakashi, being a wise and experienced ninja, might see the potential in Naruto's fox summons and offer to train him further in using them effectively.
One idea could be that Naruto summons a special fox with unique powers that helps him defeat a powerful enemy in a new and unexpected way. For example, the fox might have the ability to create illusions so strong that they can mislead even the most powerful ninjas. Another plot could involve Naruto using the summoned foxes to explore a hidden part of the ninja world that was previously inaccessible. Maybe the foxes know the secrets of an ancient ruin and lead Naruto there, where he discovers new jutsus or artifacts.
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.
It could be fire - breathing dragons. Given Naruto's own energetic and passionate nature, fire - breathing dragons would be a fitting match. They could add a new level of destructive power to his arsenal.
Sure. Fanfiction gives a lot of creative freedom. Some fanfic authors might come up with special circumstances or new abilities that enable Naruto to summon the Kyuubi. Maybe he discovers a hidden jutsu or makes a pact in the fan - made - up world of the story. This can make for really interesting reads as it twists the original Naruto story in unexpected ways.
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.
