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.
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.
Besides Obito, Sasuke could be a main character in this fanfiction. Sasuke, with his own journey of redemption and his understanding of power and the ninja world, could have an interesting dynamic with the reincarnated Obito. Also, Sakura might play a role. She could be the one who tries to heal the reincarnated Obito, both physically if he is injured during his new adventures and emotionally from the traumas of his past life.
Often, Obito is attracted to Kushina's strength and kindness. He might try to impress her with his own abilities. Their interactions could involve Obito being a bit clumsy in his attempts at first. Kushina, on the other hand, might find his eagerness endearing and start to open up to him more. They could share stories about their pasts, their dreams, which deepens their bond.
Obito's influence would likely make Naruto more aware of the darker side of the ninja world. Naruto is usually very optimistic, but with Obito's guidance, he would see the hardships and betrayals that can happen. For example, Naruto might become more cautious in his trust of others.
