One implication is that Naruto would have ultimate power and control. He could shape the universe according to his will.
If Naruto is the creator of the universe in fanfiction, it means he has the ability to set the rules for everything. All the different species, worlds, and powers within the fan - made universe would be his creation. This also implies that his values and personality would likely be imprinted on the fabric of the universe. For example, if Naruto is known for his determination and loyalty in the original series, perhaps these traits would be reflected in how the universe functions in the fanfiction. It also changes the power dynamics between him and other characters. Instead of being just a powerful ninja among others, he becomes an entity above all.
One implication is that Naruto has absolute power. He can shape and control everything in the omniverse.
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, if Naruto was Hashirama's son, the power dynamics in the Naruto universe would be completely different. Naruto might have inherited Hashirama's Wood Style from the start, which is an extremely powerful ability. This could have made him a target much earlier in life, as many would fear his potential. Also, his relationship with Sasuke might have taken a different turn. Since Hashirama and Madara had a complex relationship, Naruto's connection to Hashirama could have added more layers to the Naruto - Sasuke dynamic.
Naruto would likely become more solemn and responsible. He's no longer just a ninja protecting his village but a being in charge of an entire universe. His view on life and death would change drastically. He might also develop new abilities related to the creation and destruction of matter.
One implication is a change in his moral compass. Jashinists are often associated with dark and violent practices in the Naruto universe. So if Naruto is a Jashinist in fanfiction, it means he could be involved in actions that go against his original kind - hearted nature.
One implication is that his power levels would be off the charts. Since the Kyuubi is an extremely powerful entity, Naruto would have a whole new set of abilities.
One implication is a change in his combat style. Instead of relying on his shadow clones and Rasengan, he'd use puppets for attacks and defenses. It makes him more versatile in battle.
One implication is a change in his status. He'd have more political power and influence. For example, he could use his position to form alliances between the Whirlpool and Konoha more easily.
One implication is a change in his status. He would be seen as royalty in the context of that fanfiction. This might mean he has certain privileges and responsibilities.
Well, it's a very strange implication. It would completely distort the Naruto story. Naruto's world is about ninja clans, rivalries, and personal growth. If he's suddenly the Biblical God, it would mean a shift from his ninja - like qualities to god - like omnipotence. His relationships with his friends would also change as he'd be in a much more superior position. It's also a bit disrespectful to the religious connotations of the Biblical God as Naruto is a fictional character from a non - religious source.
