With his enemies, it would be a whole different story. They might be more cautious about attacking Naruto. Some might even try to find a way to use the god sealed in him for their own purposes. And Naruto's relationship with the hidden villages could also change. They might see him as a potential threat or a very valuable asset.
It makes him more powerful, which could lead to overconfidence at first. But as he realizes the great responsibility that comes with the god's power, he becomes more mature. For example, he might be more cautious in battles, thinking not just about winning but also about the consequences of using the god - like abilities.
Naruto's relationship with his friends in Konoha would also change. They would be both in awe and a bit scared of him. Some might distance themselves out of fear, while others, like Shikamaru, would try to keep a close eye on him to make sure he doesn't do anything dangerous. His friends would also worry about Naruto's well - being, as having Kaguya sealed in him could potentially put a strain on his body and mind.
In many such fanfictions, it could be a variety of deities. It might be an ancient and powerful god from Naruto's world's mythology that the story's author has chosen to insert. For example, it could be a god of elements like a super - powerful fire god, which could give Naruto even more control over his existing fire - based jutsu and new, more extreme abilities related to fire.
Well, Naruto might become more mysterious. Since Gaster is an unknown and rather enigmatic entity, Naruto could start having strange thoughts or powers that he doesn't fully understand at first. He might seem more withdrawn as he tries to figure out what's going on inside him, and his normal cheerful and straightforward personality could be clouded by the presence of Gaster.
Well, it could greatly enhance his physical strength. With a dragon's power, Naruto might be able to deliver more powerful punches and kicks. His speed could also increase as the dragon's energy might boost his reflexes. And his chakra, which is already quite strong, could be amplified to new levels, allowing him to perform more powerful jutsus with ease.
Well, if Cloud is sealed in Naruto in fanfiction, it could greatly enhance Naruto's power. Maybe he could control new types of jutsus related to cloud elements, like cloud - based attacks or defenses. This would make him even more formidable against his enemies.
His friends in Konoha like Shikamaru and Kiba would see Naruto in a new light. They might rely on him more for protection, but also feel a bit of distance because of his elevated status. Naruto would have to work hard to maintain his old friendships and show them that he's still the same person deep down.
Naruto having Shukaku sealed in him would be a huge shift in his character development. He's already got the Nine - Tails, and adding Shukaku would double the tailed - beast trouble. He might start to question his own identity more, as he's now not just the host of Kurama. His power levels would skyrocket, but he'd have to learn to control two very different and powerful entities. His relationships with Sasuke and Sakura would be strained as they worry about his new situation. And his journey to become Hokage would have a whole new set of challenges related to his new - found dual - tailed - beast status.
His relationships with his friends might become stronger. Since he can see more clearly with his god eyes, he can better protect them. His friends would trust him more knowing he has this extra power to keep them safe.
His abilities would change in multiple ways. Firstly, his chakra control might be affected. Since Godzilla is a massive and powerful entity, it could disrupt Naruto's normal chakra flow. However, he could also learn to harness Godzilla's power within him. For example, he might be able to use Godzilla's raw strength to enhance his Sage Mode or even his Nine - Tails transformation. This could make him an even more formidable opponent. His speed could also be enhanced as Godzilla's power might give him a boost in his physical capabilities, allowing him to move faster and react quicker in battle.
