A likely main summon could be Gamabunta. He's big, powerful, and has a long - standing relationship with Naruto. He could teach Naruto some really advanced water - based jutsu.
Kakashi would probably raise an eyebrow and make a dry joke about Naruto's new look. But he would also be ready to help if Naruto was in some sort of trouble because of it. As for Lee, he might see it as a new form of training or a way to build character. He would encourage Naruto to embrace his crossdress toad look and use it to his advantage in some way, like scaring opponents in battle. Naruto's other friends like Ino would probably gossip about it at first but then get used to it over time.
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.
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.
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.
I recommend "The Hakone Serpent of the Wilderness." This novel was about a female protagonist with a heavenly eye who was kidnapped by an unscrupulous Taoist to become the disciple of the big liar, Shen Nong. Among them, the Hakone Serpent was one of the most important villains and was known as one of the Nine Beasts. In the novel, it would be summoned to fight against the main character and the others. I hope you like this fairy's recommendation. Muah ~😗
Often, in these early fanfics, Naruto might show a quicker mastery of toad - related jutsu compared to the original series. His connection with the toads could be more profound from the start.
In many fanfictions, beetle summons are depicted with a strong sense of loyalty to their summoners. They'll follow commands without hesitation, even in the face of great danger.
In Naruto fanfiction, some of the often - considered most powerful summons are the Ten - Tails. It's an extremely powerful and ancient being. Another could be the Sage of Six Paths' summon, if there is such a concept in certain fanfictions. These are usually depicted as having near - god - like powers and can change the course of battles completely.
