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.
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.
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.
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.
They would probably feel a great deal of guilt. Minato, as Obito's teacher, might think he failed in guiding him. Kakashi would likely be devastated, seeing how his actions towards Obito led to such a dark future. Rin might be heartbroken to see the man she cared about become so corrupted.
Naruto could be one of his allies. Naruto has this knack for seeing the good in people and would probably be willing to give Obito a chance to redeem himself. Also, Sakura, with her skills as a medic - ninja, could be an ally. She might help heal Obito if he was injured during the war and see the potential in him to be a force for good.
In many fanfics, Harley Quinn realizing Bruce is Batman can lead to some really interesting plot developments. Maybe she discovers it by accident, like seeing Bruce act in a way that's too similar to Batman's mannerisms. It could also be that she pieces it together from some clues that others have overlooked. This realization might make her re - evaluate her relationship with both Bruce and Batman, and it could create a whole new dynamic in the story.
There could also be interactions with the new generation of ninjas. They might view Obito as a sort of legend or a cautionary tale. Their fresh perspectives could either inspire Obito to change further or make him feel even more out of place in this new post - war ninja world.
