In this fanfic, perhaps Naruto's godlike powers would be a result of Danzo's unorthodox training methods. Danzo could push Naruto to his limits, making him a force to be reckoned with. Naruto might also have to deal with the distrust of his friends at first, as they are suspicious of his association with Danzo.
It could be the other Hidden Villages. Since Naruto is becoming so powerful under Danzo's training, they might see him as a threat and try to stop him. Maybe they would send their best ninjas to take him down.
Well, if Naruto was trained by Danzo, he might be more ruthless at first. But joining Team 7 could soften him up. He'd probably bring some of Danzo's combat techniques and secrecy to the team. It could make for an interesting dynamic, with Naruto being a bit more of an enigma compared to his canon self.
One possible plot twist could be that Danzo, despite being 'good', has a hidden agenda related to Naruto's power. Maybe he wants to use Naruto to gain political influence in the Hidden Leaf. Another twist could be that Naruto discovers Danzo's past misdeeds while being trained, which creates a moral dilemma for him. He has to decide whether to continue training under someone with a dark history or break away.
In such a fanfiction, Naruto might become a more shadowy and ruthless ninja. Danzo's training methods are often extreme and focused on loyalty to the village above all else. Naruto could lose some of his idealism and become more of a tool for Danzo's political games.
Well, if Naruto was trained by Danzo in fanfiction, it would be a huge departure from his normal growth. Naruto is all about hope and friendship. But under Danzo's tutelage, he could be molded into a more cynical shinobi. His jutsu might develop in different directions. For example, he could be pushed to learn more dangerous and morally ambiguous ninjutsu. Also, his relationships with his friends might change as he becomes more secretive and less open - hearted due to Danzo's influence.
In this fanfic, perhaps Deadpool's training makes Naruto question his own beliefs and values. Naruto has always been about friendship and protecting the village, but Deadpool's chaotic nature might make him see things from a different perspective. As Naruto becomes more 'godlike', he has to balance his newfound power with his original ideals, and this internal struggle could be a major part of the story.
Well, perhaps Naruto, with his natural talent, is taken under Merlin's wing. Merlin could teach Naruto some really powerful magic or unique combat strategies. Maybe Naruto becomes even more powerful than in the original series and uses his new skills to protect his village in ways no one expected.
The main character is Naruto without a doubt. His journey of becoming godlike is the focus. The toads are also main characters. Big - name toads such as Fukasaku and Shima could be in it. They are likely to be the ones teaching Naruto. Their guidance and the bond between Naruto and the toads are important aspects of the story, making them all main characters in this fanfic.
