Well, in fanfiction, if Team Minato watches Obito's future, they might be shocked. For example, they would witness his alliance with Madara and all the destruction he causes. It would be a moment of self - reflection for them. Minato might blame himself for not being there for Obito when he needed it most. Kakashi would also have a hard time seeing his old friend turned into an enemy.
In a fanfiction where Team Minato meets future Obito, it could be a very emotional encounter. Minato might be shocked to see how Obito has changed. Obito, having experienced so much in the future, could bring warnings about future disasters. For example, he might warn about the upcoming threats to Konoha. Team Minato would have to grapple with the knowledge that Obito is no longer the person they once knew.
In an 'Obito kills Kakashi' fanfiction, it could start with a long - standing grudge. Maybe Obito discovers some new information that he believes Kakashi has been hiding from him all these years. This enrages him so much that he decides to take revenge and kills Kakashi in a fit of rage during a battle.
One common theme is redemption. Since Obito has made many mistakes in the original Naruto story, in time travel fics, he often gets a chance to right his wrongs through his interactions with Minato. Another theme is the alteration of fate. Time travel allows for the possibility of changing the pre - determined course of events in the Naruto universe.
Some fans would be really shocked and sad. Kakashi is a very popular character, and his death at the hands of Obito would be a huge blow to many. They might feel angry towards the author for creating such a tragic scenario.
One possible motive could be that Minato is under some sort of dark magic or mind control. In fanfiction, authors often play with the idea of characters being forced to act against their true nature. So, if Minato is being controlled, he might end up doing something as extreme as killing Naruto.
Well, there's a fanfiction called 'Time - Bound Encounter'. In this story, Obito's time travel brings him face - to - face with a younger Minato. It explores their different ideologies and how they come to understand each other better through this time - warped encounter. Also, 'The Time - Twisted Bond' is a great read. It shows how Obito's time travel alters the pre - existing relationships and how Minato reacts to the sudden appearance of this time - traveling Obito.
The implications would be huge. It would completely shatter the positive family image that the Naruto series usually portrays. Fans who love the relationship between Naruto and his parents would be very shocked and possibly offended.
When Team Minato meets future Obito, there could be a clash of ideologies. Obito, having seen the harshness of the future, might have a more extreme view. Minato, on the other hand, is more idealistic. This could lead to intense debates within the group. Also, Rin's reaction would be interesting. She might be the one to try to bridge the gap between the old Obito and the new, more hardened Obito.
Naruto would be devastated. He has always idolized his father, so being betrayed by him would shatter his world. At first, he might be in denial, not wanting to believe that Minato could do such a thing.
