Well, in Naruto fanfiction where Naruto humiliates Kakashi, it's a bit of a tricky concept. On one hand, fanfiction is a space for creativity and exploring different scenarios. But we have to consider the relationship between the two characters in the original series. Naruto looks up to Kakashi in many ways, so for him to humiliate Kakashi goes against the grain. It might be interesting if it's part of a story about Naruto growing in power and challenging his old mentors in a respectful way, but just blatant humiliation might be seen as disrespectful to the source material.
No. The use of 'cock' in the title makes it inappropriate. In the context of Naruto, which is a popular anime and manga aimed at a wide range of audiences including younger viewers, such a term is not acceptable.
In fanfiction, Sakura giving Naruto a massage could be a sign of her caring for him. It might be a moment of relaxation for Naruto, who is often so busy with his ninja duties. This scenario could also be a way to explore their relationship further, perhaps showing a more tender side to their friendship.
In the fanfiction with this title, the massage could be part of a training exercise. Sakura might be learning new medical - ninjutsu techniques related to muscle relaxation and she practices on Naruto. This could lead to some humorous moments as Naruto reacts to her sometimes clumsy attempts at the new technique.
Well, it might work as a title. If it's a fanfiction where Naruto characters are in a world with zombies or perhaps some characters are turned into zombies, this title can give a hint about the story's concept. It has a sort of mystery to it as it makes the reader wonder exactly how Naruto and zombies are related in the fanfiction.
One possibility for such a fanfic is that Naruto has been through some kind of trauma that makes him view Sasuke and Sakura differently. For example, if Naruto was betrayed by someone he trusted deeply who had similarities to Sasuke and Sakura in some aspects. It could change his perception of them completely and fuel his hatred in the fanfic.
The most immediate consequence could be a rift between Naruto and the Bleach characters. They might become enemies and start fighting. For example, Ichigo and his friends could see Naruto as a threat and try to stop him.
In this type of fanfic, Naruto might have had his own dreams and goals for the village that Sasuke and Sakura are unknowingly thwarting. Sasuke may be on a path that Naruto sees as leading to destruction, and Sakura, by being on Sasuke's side, is also seen as an obstacle. Naruto's hatred then stems from his strong sense of justice and his love for the village.
It's popular because it offers a new perspective on the Naruto universe. Fans get to see Naruto in a different role, not just as a member of an existing team but as a leader or creator of his own team. It allows for creative exploration of character relationships.
