How could Naruto's character develop if he becomes Majin Buu in fanfiction?

Well, in a fanfiction where Naruto becomes Majin Buu, the world of Naruto would be in chaos. The shinobi villages would be extremely scared of him. Naruto, as Majin Buu, could potentially use his new form to try and bring about a new order. Maybe he'd see the cycle of hatred in the ninja world differently and try to end it in a more forceful way that Buu - like. For example, he could absorb the leaders of the villages who oppose peace and then force the remaining ninja to cooperate.

In fanfiction, their relationship could develop in a really unique way. Imagine if there was a prophecy in both their worlds that only they could fulfill together. This would force them to work closely. At first, they might not get along because of their different personalities. Naruto is often headstrong and impulsive, while Female Majin Buu can be quite unpredictable. However, as they face challenges together, like powerful enemies from both universes combining forces, they would start to understand and respect each other. Naruto could teach Majin Buu about friendship and sacrifice, and Majin Buu could show Naruto some new ways of using energy and power. Their relationship could evolve into a deep and meaningful one, where they rely on each other for survival and the greater good.

If Naruto fused with Majin Buu in fanfiction, the story might start with the fusion's initial confusion about its new powers and identity. As it tries to figure things out, it could attract the attention of various villains who see it as a threat or an opportunity. The story could then be about the fusion's journey to master its powers and find its place in the world while dealing with these antagonists.

His character would become more confident. The power of the Flash would make him realize his potential even more. He'd be less likely to doubt himself in tough situations.

His character would become more cerebral. Instead of relying solely on his physical strength and ninjutsu, he'd use his intellect. He might become more patient as scientific research requires time.

One possible fanfiction could involve Naruto being transported to the Dragon Ball universe where he meets Female Majin Buu. Maybe they start as adversaries at first. Naruto, with his ninja skills, tries to fight her. But then they realize they have some common ground in their love for food. And they could end up teaming up against a greater threat in the Dragon Ball world.

Naruto's character could develop in terms of his leadership skills. As a Greek god, he'd likely have to lead or be part of the godly community. His natural leadership from being a ninja could be enhanced. He'd also have to learn to control his emotions better, as Greek gods often have tempers, and Naruto would need to find a balance between his old self and his new godly self.

Naruto's character could become more complex. He might struggle with the new power and the responsibility that comes with it. There could be moments where he fears losing control, which would add a new layer of depth to his character.

He might become more brooding and introspective as he grapples with the new power's influence.

One interesting plot could be a character who has the Majin Buu bloodline being transported to the Naruto universe. This character might initially struggle to control their unique powers, which are a combination of Majin Buu's abilities like regeneration and the ability to turn things into candy, and the chakra - based powers in Naruto. For example, they could accidentally turn a ninja's weapon into candy during a fight, creating a chaotic and humorous situation. Then, they would have to learn to harness their powers properly to fit into this new world and perhaps use their powers to help the ninja villages against a common enemy.
