One idea could be that in the fanfiction, Hinata is under the influence of a powerful genjutsu. This genjutsu makes her see Naruto as a threat to the Hidden Leaf village. So, she betrays him to protect the village in her distorted view. It could lead to a lot of inner conflict for Hinata once she realizes the truth and Naruto having to deal with the pain of her betrayal.
Hinata's betrayal could be a part of a bigger conspiracy. Maybe there are other forces at work in the ninja world that want to bring down Naruto. They use Hinata as a pawn. As the story unfolds, Naruto has to not only deal with Hinata's betrayal but also uncover the conspiracy and save the ninja world from a greater threat.
It could be Sasuke. He might be jealous of Naruto's new power and feel overshadowed. So at Wave, he decides to betray Naruto to prove his own worth.
One possible scenario could be that Naruto's girlfriend betrays him because she is jealous of his godlike powers. Maybe she feels overshadowed and in a moment of weakness, she aligns herself with Naruto's enemies. It could lead to a great internal conflict for Naruto, having to face not only external threats but also the pain of betrayal from someone he loved.
I don't know for certain. Fanfiction sites have a wide variety of works, but 'lemon' usually refers to adult - themed content. Naruto and Hinata are popular characters, so there might be fanfictions about them, but the 'godlike' aspect and the 'lemon' content together make it a bit more specific. It's possible that it exists on some less - regulated fanfiction platforms, but I can't confirm.
It could be Sakura. Maybe she becomes envious of Naruto's newfound godlike status. She might feel that he has changed too much and is no longer the Naruto she knew. So, she could side with those who want to bring Naruto down, either out of jealousy or a misguided sense of what's right for the village.
One possible plot could be that Naruto, with his godlike powers, is betrayed by the village he once swore to protect. Maybe the villagers grow jealous of his strength and start to spread false rumors about him being a threat. As a result, Naruto, feeling hurt and betrayed, decides to leave the village and embark on a journey alone, facing new challenges and enemies outside the familiar setting of the Hidden Leaf.
In a Godlike Naruto and Hinata fanfiction, Naruto's newfound power could bring new challenges to their relationship. Hinata might feel a bit intimidated at first, but Naruto's kindness and love for her would break down those barriers. They could work together to protect the village, with Hinata using her Byakugan skills and Naruto his godlike abilities. Their love story could be one of mutual growth and support, as they face enemies and overcome difficulties side by side.
In a more complex scenario, Naruto could be influenced by an outside force. Let's say an enemy of Konoha uses mind - control or some form of manipulation on Naruto. They make him believe that the ANBU is the enemy of the village and that he needs to take them down. As he betrays the ANBU, he slowly starts to realize that he's been used, but by then he's already in too deep and has to find a way to fix the situation and regain the trust of his friends and the village.
The first consequence could be Naruto's emotional turmoil. He would likely feel extremely hurt and confused, as Hinata has always been someone he trusted. This could lead to him doubting his own judgment in relationships. For example, he might become more guarded in future interactions with others.
Perhaps in the fanfiction, Hinata wears a micro bikini for a special festival in the Hidden Leaf Village. Naruto is really excited to see her in it. They participate in the festival games together and Hinata's new look makes Naruto see her in a different light, more as a strong and confident woman.
