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.
Well, it could be a fan - made story where Sakura, from the Naruto series, plays a crucial role in saving Obito. Maybe it involves her using her medical ninjutsu skills to heal him from some critical injury or her strong will to bring him back from the dark side he was on.
There's a fanfic called 'Obito's New Path'. In it, Obito has a change of heart after seeing Naruto's unwavering belief in friendship. He decides to save Naruto from a dangerous plot by some rogue ninja. The story delves into Obito's internal struggle as he tries to make up for his past mistakes while saving Naruto.
One possible plot could be that Obito arrives just in time to save Rin from being captured by enemy ninjas. He uses his Sharingan abilities to outwit the enemies and then escapes with Rin. Maybe he has to fight through a horde of strong opponents, but his determination to save Rin gives him the strength to persevere.
One potential antagonist could be the Hidden Mist ninjas. They are known for their ruthless tactics, and they might target Rin for some strategic reason. Maybe they think she has valuable information about Konoha's defenses.
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.
In some fanfictions, Minato saves Naruto physically. For example, he might use his teleportation jutsu to appear right in the middle of a fight and whisk Naruto away from danger. In others, he could save Naruto spiritually. He might enter Naruto's mind, like in the fanfic 'Minato's Mind - Saving Mission', and give him the strength and confidence to overcome his inner demons. Sometimes, Minato saves Naruto from a political situation. For instance, in 'Minato and the Hidden Leaf's Politics', he uses his influence and wisdom to protect Naruto from being used as a political pawn.
In some fanfictions, Naruto saves Obito by first understanding the root of Obito's pain. Obito was driven to his actions because of the loss of Rin and his disillusionment with the ninja world. Naruto, having experienced his own share of losses, is able to empathize. He then uses his positive influence and unwavering belief in the goodness of people. For instance, he might show Obito the new, more united ninja world that he has been working towards. This gives Obito hope and makes him realize that there is still a chance for a better future, and thus he is saved.
You can try looking on fanfiction websites like FanFiction.net or Archive of Our Own. They have a large collection of Naruto - related fanfictions, and there's a good chance you'll find the 'sakura saves obito' one there.
A common plot element is Obito's change of heart. Usually, he has been a villain or on the wrong side, but then he realizes Naruto's importance and decides to save him. Another element is the danger Naruto is in, like from a powerful enemy or a dangerous jutsu.
