There are many implications. In terms of character relationships, Naruto's relationship with Sasuke would be complex as Sasuke was Itachi's brother in the original. Emotionally, Naruto might have a different set of internal struggles related to his father's past. From a power perspective, Naruto could potentially inherit Itachi's Sharingan or some of his unique abilities. This would also change how Naruto is perceived in the ninja world, as being related to Itachi, a once - feared Uchiha, would bring both advantages and disadvantages.
One implication is a shift in Naruto's character development. He might inherit different traits from Itachi. Also, the relationship between Naruto and Sasuke would be completely redefined.
One implication could be a change in Konohamaru's status. He might be seen in a different light by the villagers, having Naruto as his father.
In some fanfictions, yes, itachi can be written as Naruto's father. Fanfiction allows for a lot of creative reinterpretations of the original Naruto story. Writers might create this relationship to explore different character dynamics and plotlines.
One implication could be a change in Lucy's status. If ACNOLGIA is her father, she might be seen as more powerful or more dangerous.
It can also impact the relationships in the story. For instance, Hermione's relationship with Harry and Ron might be different. Since Severus has a complex history with Harry, Hermione being Severus' daughter could create some tension or new alliances. Also, it could change how the other characters view Hermione. They might be more cautious or more curious about her due to her newfound relation to Severus.
If Naruto becomes like Itachi in fanfiction, it would change his relationships. His friends might be a bit shocked at first. For example, Sasuke's perception of Naruto would be completely different. Naruto would also have a different role in the village. He might be more involved in the shadowy aspects of protecting the village, like Itachi was. And his enemies would have to re - evaluate their strategies against him.
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.
If Naruto is Kunou's father, it would mean a whole new set of powers for Kunou. Combining Naruto's chakra - based powers with the devil - like abilities in 'Highschool DxD', Kunou could be extremely powerful. For example, she might be able to use Naruto's Rasengan technique along with her own devil powers.
One implication is a change in their power dynamic. If Kurama is a pet, Naruto may seem more in control. Also, it can create more comical situations.
