In Haruno Sakura time travel fanfics, a common plot is that Sakura travels back to her childhood to change her relationship with Ino. Instead of being rivals, she could try to become friends earlier and together they could be more powerful. Also, she might travel back to the Chunin Exams time and use her future knowledge to outwit Orochimaru. This could lead to a completely different outcome for the exams and the future of Konoha. Some fanfics also have her time travel to a post - apocalyptic future to find a way to prevent it from happening in her own timeline.
Sasuke is a common character she interacts with. Since Sakura has always had strong feelings for Sasuke, in time travel fanfics, she might go back in time to change how he views her or to prevent him from leaving Konoha. Naruto is also often in these stories. They could team up to change the past, like preventing certain battles or tragedies. Kakashi - sensei is another one. Sakura might seek his advice or help in her time - traveling adventures, as he is very knowledgeable.
Sakura might meet the founders of the village. For example, she could meet Hashirama Senju. He was a powerful and visionary leader. Meeting him could give Sakura insights into the true origins of the village and how to better protect it. She could also learn some of the ancient ninja techniques from him.
In an 'Immortal Sakura Haruno Fanfic', one aspect that could be fascinating is how Sakura deals with the passage of time. She would have to constantly reinvent herself to avoid suspicion. She might also form relationships with characters from different generations. Her immortality could make her a target for those who want to study or use her for their own gain. This would create a lot of conflict and drama in the fanfic.
I'm not sure if there is a specific 'sakura haruno seduce fanfic' readily available. You could try searching on fanfic platforms like FanFiction.net or Archive of Our Own, but keep in mind that the content should be appropriate and in line with the platform's rules.
If Sakura travels back in time, her relationship with Sasuke would be very different. She could meet a younger Sasuke who hasn't been through all the traumas yet. She might be able to form a closer bond with him from the start and change his path. With Naruto, she could become a mentor - like figure if she travels to a time when he is younger, guiding him in a different way than in the original timeline.
One way is to start positive fanfic writing challenges within the fan community. For example, a challenge could be to write about Sakura Haruno's achievements in her ninja training. This would focus on her positive traits and abilities.
One idea could be Sakura traveling back to the time of the founding of the Hidden Leaf Village. She could use her modern medical knowledge to help during that era, and perhaps even change the way ninja training incorporated medical skills. Another plot could be her traveling to a time when a great war was about to start, and she uses her skills to prevent it by bringing the different sides together through her diplomatic skills and understanding of different ninja clans.
At first, their relationship would be very tense. Sasori is a former Akatsuki member and has done many cruel things, while Sakura is a Konoha ninja. But as they travel through time together, they would start to rely on each other. Sakura might see a different side of Sasori, perhaps a more vulnerable side that was hidden by his cold exterior. Sasori, in turn, would come to respect Sakura's strength and determination.
As far as I know, no. Popular fanfics usually tend to revolve around more common themes like romantic relationships, power - ups, or major plot - twists in the Naruto universe. The idea of a 'sakura haruno gagged fanfic' is rather unique and not something that would typically attract a large audience. But that doesn't mean there aren't some out there, just that they haven't reached a level of widespread popularity.
