Well, in such a fanfiction, Naruto could use his chakra in ways never seen before to shape the cosmos. Maybe he'd start by creating different elemental realms based on his own jutsu, like a Fire Planet made entirely of his Fire Style. And he might populate the universe with new species that have some of the traits of the ninja clans in the Naruto world.
The story could start with Naruto achieving a new level of power that transcends the known ninja world. As the creator of the universe, he'd have to deal with the balance of forces. For example, he'd need to ensure that there's not too much chaos or order. He might create some sort of council of beings from different parts of the new universe to help him govern, similar to how the Hidden Villages have their own leadership in the original Naruto story.
In this fanfiction, Naruto would be like a god. He could create stars and planets just by thinking about it. He might give certain planets unique powers or abilities, like one planet could have the ability to heal any wound. And he would also have to face challenges. There could be an opposing force that wants to disrupt his creation, and Naruto would have to use his ninja skills and newfound god - like powers to protect the universe he created.
Well, in the realm of fanfiction, the possibilities are endless. Naruto being the creator of the universe is one of those out - there concepts that some fanfic authors play with. It could be a result of the author wanting to subvert the normal Naruto narrative. Maybe they thought it would be interesting to see Naruto not just as a ninja from Konoha but as an all - powerful being responsible for the very existence of the universe. This kind of idea can also lead to exploring different themes such as power, responsibility, and the nature of creation within the fan - created story.
Well, it would be a really strange crossover. Naruto's personality is so different from what we'd expect in a world related to Endeavor. Maybe Naruto would bring his ninja skills to that world and try to use them in a heroic way, like he did in the Naruto world. He might also struggle with the different power systems there.
Well, Naruto could gain dragon - like powers such as breathing fire or flying. His ninja skills combined with dragon abilities would make him nearly unstoppable. Maybe he'd use his new form to protect Konoha from a greater threat than ever before, like an army of powerful demons. He could also use his dragon form to travel long distances quickly to gather information or allies.
In a Naruto - Sith Empire fanfiction, Naruto would be a fish out of water. The Sith Empire has its own set of rules, based on the dark side of the Force. Naruto, on the other hand, is used to the shinobi world. But he has a strong will. He could potentially learn about the Sith's use of the Force and incorporate some of it into his own fighting style. This would make him an even more formidable opponent. At the same time, he could be a source of hope for those in the Empire who are oppressed by the more cruel Sith Lords.
In this type of fanfiction, Naruto's death while protecting Hinata could be the turning point of the whole story. It could cause a shift in the power dynamics of the village. Hinata, on the other hand, would be deeply affected. She might become more withdrawn at first, but then gradually find the strength within herself. His death could also inspire the younger generation to be more like Naruto, always ready to sacrifice for the ones they love.
Well, if Naruto had the Sharingan and Rinnegan in a fanfiction, he'd be insanely powerful. He could use the Sharingan's abilities like predicting movements and copying jutsu, and the Rinnegan's powers which are even more god - like. Maybe he'd use the Rinnegan to access different dimensions and with the Sharingan, be an even better fighter in close combat. His enemies would be completely outmatched.
In such a fanfiction, Naruto's character would likely be very different. He might have a darker side influenced by Orochimaru's experiments and thirst for knowledge. His jutsu could be a mix of Orochimaru's snake - based techniques and the traditional Uzumaki - Namikaze powers. For example, he could use snake - like rasengan variations. Also, his relationships with other characters would be strained. The Hidden Leaf Village might be more suspicious of him due to his connection to Orochimaru.
Well, if Naruto and Rukia were married in fanfiction, their relationship would be quite unique. Naruto is all about never giving up and his energetic nature could contrast with Rukia's more reserved personality. They might have a home in both Konoha and Soul Society. Naruto could learn about the spiritual powers from Rukia and use it in his own battles. Rukia would be introduced to Naruto's love for ramen, and they'd have some really fun cultural exchanges.
Well, one way the story could unfold is that Naruto would inherit some of Kratos' rage and strength. He might have an even more intense battle spirit. For example, in a fight against a powerful enemy like Pain, he could tap into that Kratos - like fury to overpower his foes. His physical abilities could be enhanced, making his Rasengan even more destructive.
In a Naruto in the Matrix crossover fanfiction, Naruto would bring his own values of friendship and loyalty. He'd be shocked at first by the lack of real nature in the Matrix. His training as a ninja would give him an edge in combat within the Matrix. However, he'd also have to learn about the Matrix's rules. Maybe he'd start by trying to find a way to use his chakra to hack into the system, much like Neo learned to manipulate the Matrix code.
