In this fanfic, it might be that Merlin sees Naruto's potential not just as a ninja but as someone who can master a different kind of power. He could train Naruto to combine his ninja abilities with magic. For example, Naruto could use his shadow clones in new ways with the help of Merlin's teachings, like sending clones to gather magical energy or perform magical tasks. This would make Naruto a truly formidable force in the Naruto universe.
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 plot could also involve Naruto traveling to different realms or dimensions with Merlin. They might encounter new enemies and allies. Naruto, under Merlin's training, would learn to adapt and use his skills in various environments. He could gain knowledge about ancient magic and use it to enhance his existing jutsus. This would lead to him being considered godlike as he would have powers far beyond what normal ninjas possess.
Obviously, Naruto and Merlin are the main characters. Naruto is the one being trained, and Merlin is the trainer.
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.
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.
One aspect of the plot could be Naruto's struggle to control the new power. The Godlike Sharingan is a powerful and potentially dangerous ability. Naruto might initially have a hard time adjusting to seeing the world through the Sharingan's perspective. Itachi would then have to guide him through this process. Also, they could face enemies who are after the power of the Godlike Sharingan that Naruto now has, leading to intense battles where Naruto has to use his new skills and the knowledge Itachi has imparted to him.
Well, the plot could involve Naruto reaching new levels of power under Scorpion's training. Maybe Scorpion teaches Naruto some unique and deadly jutsu that Naruto combines with his own skills. For example, Scorpion might show Naruto how to use puppet - related techniques in combat, which Naruto could then adapt to his shadow clone jutsu, creating an army of puppet - controlled clones.
Well, in such a fanfiction, it might be that Naruto becomes extremely powerful like a god. Since he is trained by the Kyuubi, he could gain unique powers and abilities. Maybe he masters the Kyuubi's chakra in ways no one else has. He could use this power to defeat powerful enemies, protect his village in extraordinary ways, and perhaps change the entire shinobi world with his new - found god - like strength.
The plot could involve Naruto learning Darkseid's powerful and dark techniques. Maybe he struggles with the morality of using such dark powers while also becoming extremely powerful. For example, he might use his newfound strength to protect Konoha in a way that scares his friends at first because of its intensity.
One possible plot could be that Naruto, under Kaguya's training, gains godlike powers at an accelerated rate. He might learn ancient and powerful jutsu that were once exclusive to Kaguya. This could lead to him facing new and extremely powerful enemies, perhaps even threats from other dimensions. With Kaguya's guidance, Naruto could also gain a deeper understanding of the chakra and its origins, and use this knowledge to reshape the ninja world for the better.
In such a fanfiction, Naruto could gain unique powers. Shendu, being a powerful and often devious entity, might train Naruto in unorthodox ways. Naruto could learn new combat styles and perhaps some dark or ancient techniques. This would likely put him at odds with his usual ninja values at first, but he'd probably find a way to blend the new knowledge with his own beliefs to become an even more formidable shinobi.
One possible plot could be that Naruto, seeking to gain new powers, somehow ends up in Ichigo's world. Ichigo, seeing Naruto's potential, decides to train him. Naruto then has to adapt to Ichigo's training methods which are different from what he's used to in Konoha. As he trains, he starts to combine his ninja techniques with Ichigo's Soul Reaper powers, becoming a truly godlike figure.
