Naruto's personality would be a complex mix. On one hand, he would still be the Naruto who wants to protect his friends and village. But with Majin Buu inside him, he could develop a darker side. He might start to question his own values more often. For instance, Buu's disregard for life in some cases could make Naruto wonder if there are situations where he should be more ruthless. However, Naruto's experiences and his relationships with people like Iruka, Sasuke, and Sakura would constantly pull him back from going too far astray.
Naruto's friendly nature might be at risk. Majin Buu's more violent and self - centered tendencies could seep into Naruto's mind. He might have moments where he's more aggressive towards his enemies than before. But Naruto's core of kindness might still try to shine through, leading to an internal battle between his own self and Buu's influence.
Well, Naruto would likely face a huge internal struggle. Majin Buu's chaotic nature might constantly try to take over Naruto's body. Naruto's own strong willpower, like what he showed against the Nine - Tails, would be put to the ultimate test. He'd probably have to deal with sudden surges of power that are difficult to control.
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.
One way could be through a crossover device like a mysterious portal. Maybe Naruto and his friends are on a mission and accidentally stumble upon a portal that leads to the Dragon Ball universe where Majin Buu exists. They could initially mistake him for a new type of tailed beast. Then, they have to figure out how to deal with his unpredictable power and his appetite for destruction, which could add a whole new level of chaos and adventure to the Naruto storyline.
His character could develop in many ways. At first, he might be confused by his new form and powers. As Majin Buu, he could start to explore the darker side of power, but his underlying good nature as Naruto might gradually resurface. He could learn to use his new powers for good in a different way than he did as a normal ninja. For example, instead of just fighting villains, he could use Buu's absorption power to take away the negative emotions of people causing trouble in the ninja world.
He could become more protective. Since Kiva's powers are powerful, Naruto might feel a greater sense of responsibility to protect his village and friends. He might also be more secretive about his new powers, at least until he fully understands them. And his sense of humor might change a bit, becoming a bit darker or more sarcastic as he gets used to his new identity as someone with Kiva - like abilities.
Naruto's personality might still shine through even as an Arrancar. He's always been determined and kind - hearted. However, he could become a bit more solitary at first as he adjusts to his new form and powers. The Arrancar nature might make him more cautious in some ways, but his basic values of friendship and protecting the weak would remain. He might also develop a bit of an edge, as Arrancars are often seen as more menacing, but it would be a surface change. Deep down, he'd still be the Naruto who wants to bring peace and joy to his village.
In a fanfiction where Naruto fuses with Majin Buu, there could be some really wild power combinations. Naruto's chakra and Buu's unique abilities like regeneration and absorption might create a super - powerful being. For example, Naruto could potentially use his Rasengan with Buu's stretchy body to create new and unpredictable attacks.
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.
His personality might become more somber. Having the Shinigami inside him could make him more aware of death and the finality of things. He might be less reckless in battles as he now has a constant reminder of the seriousness of death.
Some characters might be very cautious. For example, Sasuke would likely be suspicious and keep his distance at first. He would see this new power as a potential threat to his goals. Naruto, on the other hand, would probably be more open - minded. He might approach the person with the Majin Buu bloodline with curiosity and a desire to be friends. Kakashi would be more analytical. He would try to observe and understand the nature of the power before making a judgment.
