One idea could be that Dark Hinata travels back in time to change the outcome of a crucial battle. He uses his knowledge of future events to outwit his enemies and save his comrades. This could lead to a whole new timeline where things are different for the better.
It could be a future version of himself. If Dark Hinata travels back in time, his future self might see this as a threat to the timeline he has created and try to stop him. This would create an interesting internal conflict within the character.
I really like 'Hinata's Time - Travel Twist'. In this fanfic, Hinata accidentally travels back in time due to a strange jutsu gone wrong. She has to figure out how to get back to her own time while also dealing with the past versions of her friends and enemies. It has a lot of great character development and shows Hinata in a whole new light.
There's also 'Hinata's Time Travel Quest'. This fanfic focuses on Hinata traveling back to her childhood. She uses her new - found knowledge from the future to train harder and also to change the way she was perceived in the past. It has a lot of character development and shows a different side of Hinata that we don't often see in the original series.
In many such fanfictions, Naruto and Hinata might be sent back in time through some magical or jutsu - related means. Once they meet their parents, it could be a very emotional moment. Naruto might see his father Minato and mother Kushina, and Hinata could meet her father Hiashi. They could learn a lot about their families' pasts and perhaps even change some things for the better in the timeline.
A popular one is 'Hinata's Time Travel Adventure'. In this fanfic, Hinata goes back and has to deal with her past self as well as the various challenges of the earlier time period. It's full of emotional moments and her character development is really well - written. The interactions she has with other characters, especially Naruto in the past, add a lot of depth to the story.
Their relationship would likely become closer. Sharing the experience of time travel would create a unique bond. Sasuke might start to see Hinata in a new light, noticing her courage and determination. Hinata would also get to know Sasuke on a deeper level, understanding his past traumas better.
The concept of time travel in Hinata fanfiction is appealing because it allows for a fresh take on the character. We can see Hinata in different situations and how she would react. For example, she could use her time - traveling knowledge to become stronger or to help others in ways she couldn't before.
One common theme is redemption. For example, Hinata might travel back in time to try and save Sasuke from his darker path. Another theme is the exploration of alternate relationships. Since Hinata and Sasuke don't have a major relationship in the original Naruto series, in these fanfictions, their relationship gets explored in new and interesting ways.
One common theme is redemption. Hinata might go back in time to right the wrongs she or others have committed in the original timeline. Another theme is love. Since Hinata has feelings for Naruto, time travel can be a way to explore a different kind of relationship development, like falling in love all over again in a different context.
