It could change it a great deal. For one, Obito might not be as much of a villain. His alliance with Naruto could lead to a united front against Madara much earlier. This would mean less destruction and death in the ninja world. Also, Naruto would have a powerful ally who has a deep understanding of the Sharingan and its powers. They could develop new jutsu together, changing the power dynamics in battles.
Well, their friendship would likely have a huge impact. Naruto has always been about redemption and friendship. With Obito as his friend, Naruto could influence Obito to use his powers for good right from the start. This would change the Akatsuki's plans completely. The Fourth Great Ninja War might not even happen in the same way. Instead, they could work together to reform the ninja world from the inside. Obito could use his knowledge of the darker side of the ninja world to help Naruto make positive changes. And they would be a formidable duo in any conflict that arose.
In a fanfiction, if Naruto and Obito were friends, it would rewrite the entire narrative. Naruto's influence on Obito could make Obito question his motives for revenge much earlier. This could lead to a different chain of events. For instance, Obito might reveal the truth about certain events to Naruto, like the real reason behind the Uchiha massacre. Naruto, with this new knowledge, could then take steps to prevent future tragedies. Their friendship could also inspire other characters. People like Sasuke, who has his own issues with revenge, might see the power of friendship through Naruto and Obito. This could lead to a more peaceful and united ninja world much faster than in the original storyline.
Obito's influence would likely make Naruto more aware of the darker side of the ninja world. Naruto is usually very optimistic, but with Obito's guidance, he would see the hardships and betrayals that can happen. For example, Naruto might become more cautious in his trust of others.
Their friendship in fanfiction could be really interesting. Maybe they start as rivals but then realize they have a common goal. For example, protecting the Hidden Leaf. They could learn from each other's jutsu. Naruto could learn about space - time ninjutsu from Obito while Obito could learn about Naruto's positive attitude towards life.
His personality would change in several ways. For one, he'd have to be more cautious. Obito was involved in a lot of secretive and dangerous operations. Naruto would have to adapt to this new level of secrecy. Also, he might become more brooding as he tries to understand Obito's darker motives in the original story. But ultimately, his strong belief in friendship and his never - give - up attitude would still be there, and he'd use them to make different choices than Obito did.
Their friendship could also lead to a different perspective on the Uchiha clan's situation. Itachi's actions were complex and his friendship with Naruto could have made Naruto more involved in the Uchiha clan's affairs. This might have led to a different solution to the conflict between the Uchiha clan and Konoha, preventing the massacre. In turn, this would have a huge impact on the political situation in the ninja world.
If Naruto was the son of Kronos in fanfiction, it would completely upend the Naruto storyline. Kronos is from Greek mythology and has powers like time manipulation. Naruto might inherit such abilities, which would make his battles very different. He could potentially manipulate time to dodge attacks or age his opponents. His journey to become Hokage might be overshadowed by his newfound divine heritage and the powers that come with it.
Well, if Naruto had a zanpakuto in a fanfiction, it would completely shift the power dynamics. The zanpakuto has unique abilities in the Bleach universe. Naruto's existing jutsu and combat style would be blended with the new power of the zanpakuto. Maybe his Rasengan could be combined with a zanpakuto - based attack. It could also lead to new rivalries as characters from the Naruto world might be intrigued or threatened by this new power he wields.
Well, if Naruto had the Force, it would completely transform the Naruto universe. His already impressive physical abilities combined with the power of the Force would make him nearly unbeatable. He could use the Force to enhance his speed and strength even more during battles. His Rasengan, for example, could be infused with the Force to become an even more devastating attack. Also, he could use the Force to sense danger and the presence of enemies from a greater distance, which would give him a huge advantage in his ninja missions.
If Naruto were the son of Apollo in a fanfiction, it would transform the story. For one, Naruto's appearance might change to have more of an otherworldly or godly look. His training would not be just about learning ninja skills but also about mastering his divine heritage. The village's perception of him would also shift. Instead of being an outcast because of the Nine - Tails, he might be feared or revered because of his connection to Apollo. His enemies would also be more cautious, knowing he has godly powers at his disposal.
If Naruto was raised by Obito, his relationships would take a radical turn. With the villagers, he would be seen as an outsider or even a threat, just like Obito was in a way. His relationship with Sakura would be different too. Without the common experiences in the village, he might not have the same friendly - rival kind of relationship with her. And his relationship with the Akatsuki members could be very different. He might be more inclined to understand their motives or even join them at some point, given Obito's connection to the group. It would create a whole new web of relationships that are far removed from what we saw in the original Naruto story.
The Naruto storyline would be altered drastically. Firstly, Naruto's training would change. Instead of focusing on chakra control for Rasengan and Sage Mode, he'd be learning to mold explosive clay. His relationships might also change. His friends might be a bit more cautious around him since his new abilities are more dangerous. In battles, Naruto could target enemy bases or large groups of opponents with his new - found Deidara - like powers. He could even use the element of surprise more effectively, like when Deidara attacked Gaara. This would make Naruto a more versatile fighter and could potentially change the balance of power in the Naruto universe.
