One possible plot could be Naruto discovers his half - angel, half - demon fox nature during a life - threatening battle. His angel side gives him the ability to heal and purify, while his demon fox side provides immense power. He struggles to balance these two sides as he faces powerful enemies who are either attracted to or threatened by his unique nature.
Maybe a rogue ninja who has been experimenting with dark magic. He discovers Naruto's unique nature and wants to steal his power. He believes that by combining Naruto's angel and demon fox powers, he can become invincible. So, he sets out to hunt Naruto down and tries every trick in the book to get his hands on that power.
One plot idea could be Naruto's struggle to balance the angelic and demonic natures within him. For example, the angelic side might push him towards peace and mercy, while the demonic side could fuel his power in battles but also lead to more aggressive tendencies. He could be constantly at war with himself, trying to decide which side to listen to in different situations.
His relationship with Sasuke could be very different. Sasuke might be both drawn to and repelled by Naruto's new nature. The power Naruto wields from his dual nature could make Sasuke see him as a greater rival, or perhaps as a potential ally in a more complex way than in the original story. Naruto's angelic side could make Sasuke question his own path towards revenge, while the demonic side might make Sasuke more wary of Naruto's potential for destruction.
One common theme is the struggle for identity. Naruto, with his half - angel half - demon nature, often has to figure out where he belongs. Another theme is power control. Balancing the angelic and demonic powers can be a huge challenge.

Some characters might be more distrustful of him. In the Naruto world, people can be wary of those with strange or different natures. His half - fox side could make some characters see him as more of a threat or an outcast.
Orochimaru would be a great main antagonist. He's always been interested in power and the secrets of the body. Naruto's half - demon fox nature would be a prime target for his experiments.
