Well, 'Naruto meets Pain: The Alternate Ending' is a cool fanfic. In this story, Naruto uses a completely different strategy when facing Pain that we don't see in the original anime. It makes for a very exciting read. There's also 'Naruto and Pain: A Reconciliation' which explores what would happen if Naruto managed to convince Pain to change his ways much earlier in their encounter.
A 'sasuke meets oc fanfiction' could be really interesting. It might explore new relationships and character developments. Usually, when Sasuke meets an original character (oc), it can lead to various plot twists. For example, the oc could be from a different ninja clan with unique abilities that Sasuke has never seen before. This could either make them allies or enemies depending on the circumstances. The fanfiction could also delve into Sasuke's reaction to this new character, whether he is suspicious, intrigued, or dismissive at first.
Perhaps in the fanfic, Sakura is drunk because she's trying to numb the pain of seeing Sasuke with someone else. She's in so much emotional pain that she turns to alcohol. As she gets drunker, she starts to act out, crying and yelling about how much she loves Sasuke and how unfair it is that she's in this situation.
Sasuke might be initially surprised. He is used to the Sakura from his past, so seeing a different, more mature future Sakura could catch him off guard.
Sasuke would likely be aloof and guarded at first. He might see Batman as just another 'vigilante' like some of the shinobi in his world. Batman, on the other hand, would be cautious and try to figure out Sasuke's motives. Eventually, they could start sharing their combat techniques. Sasuke might show Batman how to use chakra in combat, and Batman could teach Sasuke about the importance of having a strong moral code.
In a Sarada meets past Sasuke fanfiction, it could be that Sarada has to keep her identity a secret at first. She might be on a mission in the past for some reason. As she observes past Sasuke, she could notice his skills and the way he interacts with others, like Naruto. This would give her a chance to understand the bond between her father and Naruto from a whole new perspective, which could be really interesting for the readers.
In the fanfiction, the interaction between Sarada and Sasuke's family could be filled with emotions. Maybe Sasuke's family has high expectations of Sarada, given her relation to Sasuke. This could create some tension at first, but as they get to know her better, they start to accept and love her.
One of the most unique 'Naruto meets Pain' fanfiction concepts is in 'Naruto meets Pain: The Reverse Roles'. In this story, Pain is the one trying to save the village and Naruto is the one causing destruction. It completely flips the original roles and makes for a thought - provoking read. Another is 'Naruto meets Pain: The Dream World' where their encounter takes place in a shared dream world, and the rules of that world change how they interact and fight.
Well, initially Sasuke would be in shock. But then, he would start to absorb the love and wisdom his parents have to offer. He might become less angry and bitter. His parents could show him a different path than the one of vengeance. This would cause him to re - evaluate his goals. He could become more patient and understanding, traits he lacked before. He may also gain a new sense of self - worth, knowing that his parents cared for him deeply, and this would reflect in his actions and decisions in the future.
Their relationship could start off very tentatively. Sasuke, being so used to solitude, might be a bit standoffish. But Hinata's gentle nature could gradually break down his walls. They might start with simple exchanges, like Sasuke noticing Hinata's Byakugan abilities during a battle or training session. This could lead to a mutual respect, and as time goes on, they could become friends and perhaps more depending on how the story progresses.
