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.
The power balance in the Naruto universe would be completely disrupted. Naruto would become an extremely overpowered character. Enemies that were once a threat might not stand a chance against him. Also, the villages might view him with more fear and suspicion due to the unpredictable nature of Godzilla's power.
Well, it could make for a really interesting story. Naruto having greed sealed in him might cause him to make some uncharacteristic decisions. Maybe he'd start being more competitive in a negative way, like trying to outdo Sasuke not just for the sake of friendly rivalry but out of pure greed for power. His interactions with his mentors like Kakashi would also change. Kakashi would probably notice this new side of Naruto and try to help him overcome it.
Well, it could be really chaotic. Naruto already has a powerful force within him with the Nine - Tails. If Sans was sealed in him too, Naruto might gain Sans' unique abilities like his teleportation and bone attacks. His fighting style would become extremely unpredictable, mixing ninja techniques with Sans' skeletal powers.
Well, his relationship with Kakashi would change significantly. Kakashi, being Naruto's mentor, would be extremely worried about Naruto. He would constantly be on guard, watching for any signs of Madara's influence on Naruto. Naruto, on the other hand, might feel a bit distanced from Kakashi as he tries to deal with this new reality on his own. With Sakura, she might be torn between her loyalty to Naruto and her fear of what Madara could do. And his relationship with the other villages would be strained. They might see Naruto as a ticking time bomb and start to isolate Konoha because of it.
In Naruto fanfiction, if Bast is sealed, it could be a creative and non - canonical plot device. It might be the author's way of introducing a new and unique element. Maybe Bast is a character from another mythology or a completely original creation in the fanfic world, and being sealed could be related to some powerful jutsu or ancient magic within the Naruto - inspired setting.
The idea of Hashirama being sealed inside Naruto in fanfiction often serves multiple purposes. For one, it's a creative way to combine the powers and legacies of two of the most important characters in the Naruto universe. Hashirama was the first Hokage and had amazing powers, and Naruto is the protagonist. By sealing Hashirama inside Naruto, it can create a scenario where Naruto has to come to terms with this new power. He may face challenges in controlling it, as Hashirama's power is very different from his own. It can also lead to new relationships in the story, like how Naruto's friends and allies react to this new development. Maybe they're worried about Naruto being consumed by Hashirama's power, or they see it as an opportunity to defeat stronger enemies. This concept in fanfiction can really expand on the existing Naruto lore and create exciting new story directions.
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.
His character would likely become more complex. He might start off confused by these new feelings of greed. At first, he could try to resist them, but as time goes on, they might start to seep into his actions. For instance, when it comes to training, instead of training to get stronger for the sake of others, he might train just to be the best and have more power than anyone else.
The ninja world would be in shock. The Hidden Villages would be very cautious around Naruto. They might see him as an even greater threat or an unknown entity. His friends, like Sakura and Sasuke, would have to adjust to this new Naruto and learn how to fight alongside him with his new powers.
