No. In most Naruto fanfics, Naruto is still depicted as the selfless hero he is in the original series. He values his friends, his village, and the greater good.
A fanfic might explore the idea that Naruto, after achieving many great things for the village, is still a bit lonely in his personal life. Tsunade, who has also been through a lot, can relate to him. They start to spend time together outside of their official duties, like having dinner or walking in the village at night. As they get to know each other better on a personal level, a romantic connection between them starts to form.
One possible fanfic could be about Naruto, Tsunade and Kushina teaming up for a special mission. Maybe they have to face a powerful enemy that threatens the Hidden Leaf Village. They each bring their own unique skills and personalities to the mission. Naruto with his determination and powerful jutsus, Tsunade with her strength and medical ninjutsu, and Kushina with her red - haired charm and her own set of skills.
One possible interesting storyline could be Tsunade teaching Naruto some unique medical ninjutsu skills. This would not only expand Naruto's abilities but also create a strong bond between them as mentor and student.
One common scenario is when Naruto is in a life - threatening battle. Sakura will be on the sidelines, worried sick and using her medical skills to the fullest to keep Naruto alive. She might even put herself in danger to reach Naruto if he's in a precarious position on the battlefield.
It could mean that in the Naruto fanfiction universe, the Kyuubi (Nine - Tailed Fox) has some sort of emotional investment or interest in the stories being written about Naruto. Maybe the fanfictions explore aspects of their relationship in new and interesting ways that the Kyuubi, in the context of these fictional tales, is somehow aware of or involved in.
One way the Kyuubi can show it cares about Naruto fanfiction is by being a consistent and important part of the stories. If the Kyuubi is always there to support Naruto, either by giving him power or by sharing its wisdom, in various fanfiction scenarios, it indicates that it has a role to play and is interested in the development of the fan - created Naruto stories. Fanfiction often plays with the relationship between the two, and if the Kyuubi is actively engaged in these new storylines, it can be seen as caring about the Naruto fanfiction.
One great 'Naruto - Tsunade' fanfic could be 'The Mentor and the Student'. It delves into Tsunade teaching Naruto some advanced medical ninjutsu, which is really interesting as it combines their different areas of expertise. Another could be 'A New Bond', where Naruto helps Tsunade deal with her past traumas related to her family and lovers, adding a deep emotional aspect to their relationship.
There could be. Fanfiction writers often come up with all sorts of creative and sometimes out - of - the - box ideas. But it's also important to note that this kind of plot might not be in line with the general tone and themes of the original Naruto series. The Naruto world has a lot of different storylines that can be explored in fanfiction, and this is just one of the many possible, albeit rather strange, ideas that might have been written about.
I'm not entirely sure if there is a specific 'Naruto sleeps with Tsunade' fanfiction. Fanfiction can cover a wide range of themes and ideas, some of which might be quite strange or far - fetched. However, if it exists, it could be a product of someone's wild imagination, perhaps exploring a romantic or platonic relationship between the two in a very different context than the original anime or manga.
