What are some interesting plot twists in a 'Past Kakashi Meets Future Obito' fanfiction?

One idea for this 'Past Kakashi Meets Future Obito' fanfiction could be that their meeting is not a coincidence. Maybe it's part of a grand plan by some mysterious force. When they meet, past Kakashi would be in awe of future Obito's power and skills. Future Obito, though, would see the innocence still in past Kakashi. They could end up training together, with future Obito teaching past Kakashi some new jutsu. And as they bond, they might rewrite their fates and change the future of the ninja world for the better.

Well, it could be about Kakashi finally finding Obito after a long search. Maybe Obito has changed a great deal, and Kakashi has to come to terms with this new version of his old friend. They might have a battle first due to their different paths, but then they start to talk and remember their past together, like their time as teammates in Team Minato.

One idea could be that an old enemy from the past resurfaces in the future, but with new and more powerful abilities. The dragons and riders have to combine their old - school knowledge with the new technology they've developed over time to defeat it.

One plot idea could be Merlin traveling to the future and finding that magic has been completely forgotten. He then has to figure out a way to re - introduce magic without causing chaos. Another could be a future descendant of Merlin's friends coming back to the past and accidentally changing the course of history, so Merlin has to fix it. A third idea is that in the future, there is a new dark magic threat that can only be defeated with the knowledge Merlin has from the past.

One idea could be a time - traveling hero from the past who gets stuck in a high - tech future world and has to adapt to new technologies while using his old - fashioned skills to solve problems. For example, a medieval knight in a world of flying cars and laser guns.

Perhaps past versions of the Crystal Gems meet their future selves. They could be shocked by how much they've changed, or they might learn valuable lessons from each other. The past Gems could see how their actions in the past led to the future they now inhabit, which could be a really interesting exploration of cause and effect.

One interesting plot twist could be that Obito was secretly protecting Naruto all along, even when he seemed to be on the side of the villains. Another could be that Naruto discovers he has some of Obito's old powers due to their brotherly connection. This could lead to Naruto having to learn how to control these new abilities in a hurry.

Perhaps in the fanfiction, Obito's identity is revealed to be a double agent for a group that was thought to be extinct. This changes the way other characters view him and the overall power dynamics in the story. He could have been working towards a different goal than what was initially assumed.

One possible plot could be that future Gohan travels back in time to warn the past about an upcoming threat that was not properly dealt with in his own timeline. He might meet the past version of himself and try to train him to be stronger, sharing his knowledge of the future battles. Maybe he also meets the past versions of his friends and family, and has to convince them of the seriousness of the situation without revealing too much about the dark future he comes from.

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.
