Who could be the main summons in 'naruto trained by summons fanfiction'?

Well, in such a fanfiction, Naruto might learn unique skills from the summons. For example, he could learn stealth from a cat - like summon or brute strength tactics from a bear - like one.

The Snakes, especially those related to Orochimaru's summons, are often used in fanfiction. They can bring an element of mystery and danger. Some fanfictions might explore the idea of a redeemed snake summon that helps Naruto in his quests, or a more powerful, ancient snake that was hidden away until now.

It could be powerful ancient scrolls that contain lost jutsu. These scrolls might give Naruto an edge in battles against tough opponents.

The female Nekomata is also quite popular. With her cat - like features and agility, she can be a great asset in battles. She may have the ability to move silently and ambush enemies. In fanfiction, she often forms an interesting relationship with Naruto, teaching him new ways to fight and be stealthy.

The fanfiction might start with Ilya performing a summoning spell that she thought would bring something else, but instead, Naruto appears. Since Naruto is always eager to make friends and help others, he quickly bonds with Ilya. They could then embark on a journey to find a way to send Naruto back home. During this time, Naruto could teach Ilya about the importance of perseverance and believing in oneself, just like he learned in his own adventures in the Naruto world.

He could have a dragon as a summon. A powerful and majestic dragon that can breathe fire or ice, which would give Naruto a huge advantage in battles.

In this fanfiction, different summons can change the power balance. Let's say Naruto summons a spirit that can nullify all chakra - based attacks. This would make his enemies have to come up with new strategies, and it could also make some of his allies jealous or fearful of his new power. The plot would then revolve around how he manages these new relationships and the power shift.

Yes, in many Naruto fanfictions, Naruto has summons. Fanfiction writers often explore different types of summons for Naruto that might not be in the original story. For example, he could have unique or powerful creatures as his summons, which adds an exciting new dimension to the story.

One possibility is that Naruto's connection with the summons would make him more in tune with nature. For example, if he was raised by toads, he might learn their unique jutsu faster and have a different approach to combat. He could also have a different view on friendship and loyalty as summons often have a strong bond with their summoners.

Perhaps they are ancient water spirits. These spirits could have the power to manipulate water in ways that normal ninjutsu can't. They could turn water into solid ice sculptures that can be used as shields or weapons. They might also be able to swim through the ground as if it was water, allowing Naruto to surprise his enemies from below.
