When it comes to his romantic relationship, if he time travels, it could be really interesting. If he goes back to a time before he met his partner, he might end up changing the way they meet or fall in love. Or if he travels forward in time, he could see how his relationship has developed over the years and make changes to ensure its longevity. His relationships with his subordinates might also change. They could view him differently, either with more respect because of his future knowledge or with some suspicion as his actions might seem out of place.
His relationship with his friends could change significantly. For example, if he travels back to a time when they were younger, he might be more protective of them. He could also inspire them in different ways, leading to stronger bonds. His relationship with his sensei might also be affected. He might be able to offer new insights based on his future experiences.
Minato's time travel can have a profound impact on his family relationships too. If he travels back to a time when his son Naruto was a baby, he could be more involved in Naruto's early life, which would change the dynamic between them. He could also go back to a time when his own parents were alive and form a different kind of relationship with them, learning things about his family history that he didn't know before, and this new knowledge could in turn affect how he relates to his family in his original time.
If Gohan travels back in time, his relationship with his father, Goku, would be really interesting. He could train with Goku as an equal, which would be a different dynamic from their usual father - son - student - teacher relationship. Goku would probably be surprised but also excited to have such a strong partner to train with.
His friends, like Ron and Hermione, would be quite surprised. Ron might be a bit jealous at first that Harry has this unique experience of traveling back in time. But then they would realize the potential of it. Hermione would be eager to make sure Harry doesn't change things too much that could have a negative impact on the future.
Time travel can completely change their missions. They might have to redo a mission they already completed in a different way. For example, if they failed a mission in the original timeline, they could go back and try to succeed this time. Or they might have a new mission altogether because of the changes in the timeline that they caused through time travel.
Time travel could also put a strain on his relationships. If Ben goes to the future and sees something bad happen to his friends or family, he might become overprotective when he returns to the present. This overprotectiveness could annoy his friends and cause friction in their relationships, as they might not understand why he's suddenly acting so differently.
His power can make his relationships more complex. For example, if he uses time control to be with a friend more often, that friend might start to feel like Percy is being overbearing. On the other hand, it could strengthen his relationships. He could save a loved one from a dangerous situation in the past, which would deepen their bond.
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.
Time travel in fanfiction often forces Eren to face his own limitations. He realizes that even with the power to time travel, he can't always control everything. This realization humbles him and makes him more empathetic. He starts to understand the complexity of the world and the fact that every action has far - reaching consequences. As a result, his character becomes more complex and well - rounded.
It would likely make his relationships very strained. He might be constantly suspicious of people's motives, thinking they will abandon him too. For example, he might have a hard time getting close to his peers like Sasuke and Sakura. He could see any kindness as a potential trap or something that will be taken away from him in the end.
His presence could completely rewrite the history of the Hidden Leaf Village. For example, if he manages to prevent the Nine - Tails attack, it would mean that many of the characters' backstories would change. People like Sasuke, who was also affected by the events related to the Nine - Tails, might have a different path.
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.
