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.
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.
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.
The impact on the Naruto universe in these fanfictions is multi - faceted. Firstly, in terms of the political situation, Obito's change of heart could mean a shift in the balance of power among the ninja villages. His knowledge of the Akatsuki's operations could be used to prevent future threats. Secondly, on an emotional level, it would bring closure to many characters who were affected by Obito's actions. For example, Minato might be able to see his former student redeemed. And finally, it could inspire new forms of ninja training or cooperation. Naruto's ability to save Obito could lead to the development of new techniques or strategies focused on redemption and rehabilitation.
In some fanfictions, Naruto might save Obito during time travel by using his strong will and the power of friendship. Naruto could convince Obito to change his ways before he goes too far into the dark side. He might show Obito the future of the village and how his actions are causing more harm than good.
Well, Naruto has a lot of unique abilities. He could enter Sage Mode and use his enhanced perception to outmaneuver Obito. Konan, on the other hand, is a very skilled fighter herself. But against Obito's Sharingan and his space - time ninjutsu, she might be at a disadvantage. Naruto could use his talk - no - jutsu to make Obito realize the error of his ways and stop attacking Konan. This would be a very Naruto - like way to end the confrontation.
Naruto's character could develop a deeper sense of responsibility. Saving Konan from Obito would show that he is not only protecting his close friends from Konoha but also those from other villages. This would expand his view of what it means to be a hero.
A major theme is the power of forgiveness. Naruto is all about forgiving others, and when it comes to Obito, this theme is often explored. How can Naruto forgive Obito for all the harm he has caused? Also, the theme of changing one's fate. Obito's fate seems set in the original story, but in fanfics, he often tries to change it with Naruto's influence. There are also themes related to the understanding of different ideologies as Naruto and Obito have very different outlooks at times.
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.
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.
