In a fanfiction where Shisui meets baby Sarada, Shisui might be feeling a bit melancholic as he has seen so much turmoil in the village. But when he sees Sarada, he feels a glimmer of hope. He may hold her gently and think about how she is the future of the Uchiha clan. He could even vow silently to protect her from the shadows, just as he has always tried to protect the village.
In this fanfiction scenario, it could be really interesting. Shisui's amusement might add a unique dynamic. He could be observing Sakura snuggling Sasuke and have various thoughts. Maybe he's secretly rooting for their relationship, or perhaps he finds it a bit comical considering their different personalities. Sasuke, who is usually so stoic, having Sakura snuggle him could be a big step in their relationship development within the fanfiction world.
One possible plot could be that Naruto accidentally travels back in time and meets Shisui. Shisui, seeing Naruto's potential, decides to train him in some of his unique jutsu. This would give Naruto an edge in his future battles and also a new perspective on the Uchiha clan.
Another possible antagonist could be a rogue Uchiha. One who didn't agree with Shisui's views on peace. This rogue Uchiha could see Naruto as an outsider interfering with Uchiha matters and Shisui as a traitor for teaming up with Naruto. So they set out to disrupt their partnership and cause chaos in the village.
In this fanfiction, Shisui could be a mentor figure to baby Sarada in a way. He might not be able to be there all the time, but when he is around, he imparts some of his wisdom. He could teach her (in a very basic sense for a baby) about the importance of loyalty and courage. He may also give her a special gift that has some connection to his own powers, like a pendant that can enhance her chakra control when she grows up, starting her on a path of becoming a strong ninja.
One possibility is that other characters will get involved. For instance, Naruto might see this and be a bit surprised or happy for his friend Sasuke. Also, the fact that Shisui is amused could spread around the village, leading to different reactions from the villagers. Some might support the relationship, while others might be against it. This could create some conflict for Sakura and Sasuke to overcome in the fanfiction.
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.
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.
