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.
The crow summon in Naruto fanfic often adds an element of mystery. Crows are associated with intelligence and stealth in many cultures, and in Naruto's world, they can be a great addition to a character's abilities. A fanfic might explore a character who has a special bond with the crows they summon, and through this bond, they gain unique powers or insights.
Perhaps Naruto's dragon - summoning is linked to an ancient prophecy. In the story, as he starts to summon dragons, it sets off a chain of events where different ninja clans either try to help him or stop him, depending on how they interpret the prophecy. The dragons could also be guardians of some long - lost ninja secrets.
With Kakashi, he would be very cautious at first. He'd want to make sure Naruto can control the dragons properly. But once he sees that Naruto has it under control, he would start to develop new strategies that incorporate the dragons into their team's combat style. This would make their teacher - student relationship more complex and interesting.
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.
Crows could be used to carry out coordinated attacks. For example, they could be equipped with small explosives or toxins and sent to attack specific targets. In a Naruto fanfic, this could be a creative and deadly use of the crow summon.
Well, it might not be as widespread as some other types of Naruto fanfics. While summoning is cool, there are many other aspects of Naruto that fans like to explore in fanfiction, such as character relationships or alternative storylines for the main plot. But for those who love the idea of summons, this kind of fanfic can be really appealing.
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.
We can expect a lot of focus on the summoning aspect. There might be new types of summons introduced, or a deeper exploration of the existing summons in Naruto. For example, more details about the summoning contracts and how they work.
It could be made more intelligent. Instead of just being a summon for combat, it could be a strategic advisor to Naruto, guiding him in his decisions with its ancient knowledge.
