A 'Naruto son of Satan' fanfic would likely be full of twists and turns. Naruto's backstory would be completely rewritten. Instead of being an orphan with a mysterious past related to the Fourth Hokage, he would be the son of Satan. This would change his goals and motivations. He might not be as focused on becoming Hokage but rather on finding his place in the world given his dark heritage. The story could also introduce new characters related to the Satanic realm. And the power dynamics in the Naruto universe would be shaken up. There would be a struggle between Naruto's good - natured side that we know from the original series and the dark side that comes from being the son of Satan.
In a 'Naruto son of Satan' fanfic, the story could take a very different turn. Naruto's appearance might change to have some more demonic features. His relationships with other characters would be greatly affected. For example, his friends might be scared or distrustful of him at first. And his enemies might see him as an even greater threat. The fanfic could also explore how the ninja world would react to such a powerful and potentially evil being in their midst. It could be full of battles between Naruto and those who want to either control or destroy him because of his Satan - related origin. There would be a lot of internal conflict for Naruto as he tries to figure out who he really is and what he should do with his powers.
In a 'naruto kills satan fanfic', perhaps Naruto, with his powerful ninja skills and determination, is somehow transported to a realm where Satan exists. He would use his signature jutsus like Rasengan or Shadow Clone Jutsu to battle Satan. Maybe Satan has been causing chaos in Naruto's world or a world connected to it, and Naruto feels the need to take him down.
Sasuke would probably be very suspicious. He's always been wary of Naruto's power, and if Naruto started showing Satan - like traits, Sasuke would see it as a threat. He might even think Naruto has finally given in to the darkness. Sakura would be shocked and heartbroken. She's always seen Naruto as a positive force, and this change would be hard for her to accept. Kakashi, on the other hand, would try to understand what happened to Naruto and see if there's a way to bring him back.
His relationship with Sasuke might become more complicated. Sasuke, who has his own dark past, might view Naruto's new identity with suspicion or envy. They could have more intense battles as Sasuke might see Naruto as a greater threat now.
It could be a wild and imaginative story. Harry, with his Gryffindor courage, might face off against a Satan - like entity that has somehow invaded the wizarding world. He could use his spells and the help of his friends, like Hermione's vast knowledge and Ron's loyalty, to combat this ultimate evil.
Well, one possibility could be that Naruto discovers his true heritage as the son of Satan later in life. This could lead to a conflict within him as he has been raised with the values of the Hidden Leaf Village. Maybe he has to struggle between his new - found demonic powers and his loyalty to his friends and village.
Well, it could be really interesting. Naruto's energetic and determined personality would contrast with Glynda's more composed and strict nature. There might be a story where Naruto has to adapt to a new world while still carrying his ninja spirit. Maybe he'd use his shadow clone jutsu to get out of trouble at school, or his rasengan in some kind of epic battle against the Grimm. It would also be fun to see how Glynda would handle having such a wild - card son.
The plot might be centered around Naruto's discovery of his Greek god heritage. It could start with some strange events that he can't explain with his normal ninja knowledge. As he delves deeper, he finds out that he is the son of a Greek god. This would then lead to him being trained in a different way, perhaps by some mysterious figure sent by the Greek gods. His relationships with his friends in Konoha would also change as they try to understand his new powers and identity.
Well, it would be really different from the original story. Maybe Naruto would inherit some of Madara's powers and have a darker side to him. He might also face a lot of inner conflict, since Madara was a complex and often villainous character.
In such a fanfic, the story could start with some sort of magical or dimensional rift that brings Naruto into the Fairy Tail universe at a young age. Erza, being the strong and motherly figure she is, takes him in. Naruto would have to adapt to a world full of magic, while also bringing his own unique abilities. There could be a lot of conflict as Naruto tries to fit in and also as the Fairy Tail world has to deal with a character from a completely different realm. His journey to become a great mage - ninja hybrid could be the main focus of the story, with him making friends and facing enemies along the way.
It would be a strange mix. Naruto might have some of Wesker's cold and calculating side along with his own ninja spirit. There could be epic battles where he uses both ninjutsu and Wesker - like powers.
