The fanfic could give Naruto the power to summon divine weapons along with the god. For example, the god could bring a sword that can cut through any chakra - based defense.
One idea could be that Naruto discovers a new and extremely powerful summoning scroll that allows him to call forth a god - like being from a forgotten realm. This being could teach Naruto a new form of chakra control that is far more advanced than what he has learned before.
In a snake summon Naruto fanfic, there could be a plot where the snake summons are from a different dimension. These snakes have their own culture and hierarchy. The story could follow a group of ninjas, including some of the main characters from Naruto, as they explore this new dimension through their connection with the snake summons and have to deal with the political and power struggles within the snake society.
One possible fanfic could involve Shirou using some kind of magic or special ability to summon Naruto. Maybe Shirou is in a difficult battle and needs Naruto's strength. Naruto could arrive with his signature orange jumpsuit and start using his shadow clone jutsu to turn the tide of the battle. It would be an exciting crossover of the Fate and Naruto universes.
One possible fanfic could involve Raven using some sort of dark magic or special jutsu to summon Naruto from his own world to hers. Maybe she needs his help to fight off an evil force in her realm that her own powers are insufficient to defeat. Naruto, with his never - give - up attitude and powerful ninjutsu, could bring a new dynamic to Raven's world.
In Naruto fanfics, the demon god often represents a powerful and mysterious force. It could be an ancient entity with great power that can either be a threat or an ally to the characters. For example, it might possess unique abilities like controlling dark chakra or having the power to manipulate time and space in the fanfic's unique lore.
In DC fanfic, Naruto could be considered a god perhaps because of his powerful ninja abilities. His jutsus like the Rasengan or Shadow Clone Jutsu might be so extraordinary in the DC universe context that they seem god - like. Also, his ability to endure and keep fighting could be seen as a divine trait.
Fanfics are known for their creativity and bending of established ideas. When it comes to Naruto being the Biblical God in a fanfic, it's a unique blend that probably emerged from someone's very creative and perhaps even a bit irreverent mind. Naruto has his own story arc, friends, and enemies in his native series. The Biblical God has a vast and complex religious narrative. In the fanfic world, this combination might be used to explore new power dynamics, moral questions, or just to create a really out - there story, but it has no basis in either the Naruto canon or the Bible.
Obviously, Naruto is the main character. He is the one who becomes this 'god - like' figure in the fanfic. But there are also other important characters like Sasuke. Sasuke might play a role in either supporting Naruto's new power or being in conflict with him because of it.
I'm not sure if it's popular. There are so many Naruto fanfics out there, and it's hard to say which ones are popular without checking fanfic platforms and their rankings.
