His sense of justice might shift. In the Naruto universe, the concept of justice is often complex, with different villages having different views. Hibari might start to see things from a broader perspective and not just his own narrow view of maintaining order, which could make him more open - minded.
He might become more lenient. In the Naruto world, there is a greater emphasis on teamwork and friendship compared to his original world. So, he could gradually soften his strict and solitary ways as he experiences the bonds that the ninjas form.
Naruto's personality would be a blend. He'd keep his core values like loyalty and his love for his friends. However, being in Cell's body, he'd have to adapt. He might become more reserved in some ways because Cell wasn't as open as Naruto. But he'd still find ways to show his Naruto - ness, like when it comes to facing challenges head - on and never giving up. He'd also have to handle the power - hungry side of Cell's nature, but he'd probably try to turn it into a drive to protect rather than conquer.
Naruto might become a bit more reserved at first. Since Tsuna's world is different from Naruto's, he'd have to adapt. But his core of being kind - hearted and determined would remain. He might be more cautious as Tsuna initially isn't as bold as Naruto was in his own world.
Hibari Kyoya could be a mentor figure in the Naruto fanfiction. He might teach Naruto some new techniques or ways of thinking that are different from what he has learned from Kakashi or Jiraiya. This could open up new storylines about Naruto's growth as a ninja.
His personality would be a blend. He would have Kakashi's calmness in high - pressure situations. But at the same time, Naruto's exuberance would peek through at times. For instance, when he's around his friends or when he's really passionate about something. He would be more introverted in general but would still show his Naruto - like enthusiasm on certain occasions.
Well, in Naruto fanfiction, Hibari Kyoya could be an interesting addition. He might bring in his unique combat style and personality. Maybe he could be a visiting ninja from another village, interacting with Naruto and his friends in unique ways. For example, he could have some sort of rivalry with Sasuke due to their different approaches to power.
He might become more outgoing. In the Naruto world, the culture is different from the rather formal and often secluded wizarding world. Harry would be exposed to a more boisterous and open - minded society, so he could become more extroverted and less reserved.
If Naruto were on Team 8 in fanfiction, his personality could develop in several ways. He may become more empathetic as he gets to know his new teammates better. Hinata's shyness might make him more sensitive to others' feelings, and he would try to encourage her more. Also, being around Shino's quiet and methodical nature could make him more reflective. He might start thinking more about the consequences of his actions before acting, which is a big change from his usual impulsive self. He could also become more competitive in a different way, trying to prove himself not just in combat but also in the more specialized skills that Team 8 values, like tracking and espionage.
Another plot could involve Hibari getting involved in the Akatsuki's plans. Maybe he initially misunderstands their motives and gets caught up in their activities, only to later realize their true nature and try to stop them. This would bring a new dynamic to the Akatsuki's story.
He'd probably be more timid at first. Tsuna is known for being a bit of a wimp in the beginning, and even though Harry has his own insecurities, being in a new world and a new body might make him even more hesitant. But as he gets used to things, his brave side from his past life would start to show more. He'd still have that sense of justice and a willingness to protect his friends, just like he did in the Harry Potter world.
He might become more cautious. In the DC Universe, there are a lot of powerful and unpredictable entities. So, he could tone down his cocky side a bit.
