Maybe a new, original god - like character created specifically for the fanfiction. This character could have its own set of powers and motives. It could be a being from a different dimension that has an interest in Naruto for some reason. For example, it might see Naruto as a key to balance the forces in the Naruto world or something more complex like that.
Well, in some fanfictions, it might be a more abstract or self - created god - like being. However, a popular choice could also be Odin from Norse mythology. Odin is known for his wisdom and power, and raising Harry Potter would give the story a whole new Norse - influenced magical flavor. Harry could learn different forms of magic related to Norse runes and such.
Apollo could be the most interesting. Imagine Percy growing up with Apollo's gifts of music, poetry, and healing. He'd be this multi - talented demigod. He could use his music to charm monsters or his healing skills to save his friends in a more unique way than just using a sword. Plus, Apollo's flamboyant personality might rub off on Percy, making him a more colorful character.
Perhaps it could be Thor from Norse mythology. Thor is the god of thunder. So, Harry could have the power to control lightning or storms. He would be a very formidable wizard with such powers. His Hogwarts years would be full of situations where he uses these thunder - related powers to solve problems or fight off enemies.
Another possibility is that Naruto's 'god' parent is an actual deity from Japanese mythology. Since the Naruto world is inspired by Japanese culture, it would make sense for a kami (god) from their mythology to be Naruto's parent. For example, Amaterasu, the sun goddess. Her power could be passed down to Naruto, giving him abilities related to fire and light.
It could be an ancient, long - forgotten god from the Naruto universe's mythology. Maybe a god that was sealed away because of its malevolent nature. For example, a god that thrives on chaos and destruction.
Well, in a 'Naruto Raised by God' fanfiction, Naruto might gain extraordinary powers. He could have a divine connection that makes him much stronger than in the original story. Maybe he'd be able to use god - like jutsus or have a special understanding of the world's secrets.
Poseidon is a likely candidate. Since he is Percy's father in the original series, it would make sense for him to take a more active role in raising Percy. He could teach Percy all about the ocean, its secrets, and how to use his water - related powers more effectively.
It could be an evil ninja who has already made a pact with the Abyssal God and wants to use its power to take over the ninja world. He might see Naruto as a threat to his plans because Naruto has a natural connection to the god's power.
Maybe an ancient being that was sealed away long ago but has now been awakened due to Naruto's newfound power. This being has a natural hatred for those who can control lightning and sees Naruto as a threat to its plans of taking over the ninja world. It has the ability to manipulate shadows and uses them to counter Naruto's lightning attacks.
Perhaps an evil Pokemon scientist who has created a device that can control the minds of Pokemon. He discovers Naruto's arrival and sees him as a threat. So, he teams up with some of the most powerful and aggressive Pokemon to stop Naruto. He has no regard for the well - being of Pokemon or the balance of the world, only his own ambition to rule.
