Maybe there's a special chakra - based artifact. In Naruto, there are many powerful artifacts. If there was an artifact that was linked to the concept of time and had the ability to grant immortality, it could be a key factor in time travel. The character would need to find and unlock the true power of this artifact. It could be hidden in a dangerous place like an ancient temple or a secret dimension.
There could be a personal cost. Even though the character is immortal, they might face mental and emotional challenges. Watching the same events unfold over and over again or being unable to fully change the future despite their efforts could drive them to madness. Also, they might be hunted by those who fear their power of time travel and immortality in the Naruto universe.
One way time travel redemption could be done in Star Wars fanfiction is through the Force. A character could use a powerful Force ability to go back in time. For example, they might go back to a point where a key villain was on the verge of turning bad. By intervening at that moment, perhaps with a display of kindness or a warning, they could change the course of that character's life, leading to their redemption. It could also be achieved through some sort of time - traveling device, like a modified hyperdrive or an ancient Sith artifact that has the power to manipulate time.
In many Naruto yaoi time travel fanfictions, it can be triggered by a powerful jutsu. For example, a secret time - space ninjutsu might go wrong and send a character back in time.
If they travel together through time, their relationship becomes more of a partnership. They have to rely on each other in a different time period. This shared experience of exploring different eras and facing challenges together can make their bond even stronger. They might discover new things about each other that they never knew before, like Naruto finding out how brave and resourceful Himawari can be in a completely unfamiliar situation.
In time travel fanfiction, if Jiraiya goes back, it can have a huge impact on his relationships. He may be able to save some relationships that were lost in the original timeline. For instance, he could repair his broken friendship with Orochimaru. Regarding his relationship with Naruto, if he travels back to Naruto's childhood, he can be a more effective teacher and friend. This could lead to Naruto trusting him even more. And if they travel back together, they rely on each other more in the different time period, which enhances their bond.
The Rinnegan can be used in time travel fanfiction in Naruto in various ways. It could be used to open portals to different time periods, kind of like how it can create spatial portals in the original series. For example, a character might use the Rinnegan to travel back to the era of the First Hokage to gain knowledge or power.
If Minato time - travels, it could change a lot. For instance, if he prevents the Nine - Tails attack, Naruto would grow up in a very different environment. He might not be the underdog he was in the original story. Also, if Minato changes things during the Uchiha clan's situation, Sasuke's story would be completely different. Konoha's political situation would also be altered. There would be less animosity between different clans perhaps.
One way is through time - travel jutsu. A character could accidentally or intentionally use a jutsu that sends them to the future or past. For example, Naruto might find a hidden scroll with a time - travel jutsu and end up in the future where he sees how his friends and the village have changed. This could lead to interesting storylines where he tries to fix things or learn from the future.
One way for Hinata to move on could be through self - discovery. In fanfiction, she might focus on her own personal growth outside of her feelings for Naruto. She could explore new hobbies or develop her skills. For example, she could train more intensively in her ninja abilities, which would not only make her stronger but also give her a new sense of purpose. Another aspect could be making new friends. Instead of always being centered around Naruto and his circle, she could interact with other characters in the Naruto universe who she hasn't had much to do with before. This would expand her social circle and give her different perspectives on life.
In a time - travel scenario, Naruto and Shizune's relationship could evolve in many ways. If they travel to a dangerous time, like during a war, they would have to depend on each other for survival. Naruto's combat skills and Shizune's medical support would be crucial. As they work together, they would start to understand each other better. Naruto might open up more about his feelings and dreams, and Shizune would share her own experiences. This could lead to a deeper bond between them, not just as comrades but as true friends who care about each other's well - being.
