Well, in such a fanfiction, Sasuke might be taken to Orochimaru's lair. There, Orochimaru could try to force Sasuke to accept his power - like the cursed seal. Sasuke, being strong - willed, would likely resist at first. But Orochimaru has his ways of persuasion. Maybe he'd show Sasuke some dark jutsu that could make Sasuke more powerful. And Sasuke, who's always eager to gain power to avenge his clan, might start to consider Orochimaru's offer despite the risks.
One possibility in this fanfiction is that Orochimaru has a different motive for kidnapping Sasuke. Instead of just wanting Sasuke's body as a vessel, he might want to use Sasuke to get to some ancient power. Sasuke, not knowing Orochimaru's true intentions, is caught in a web of lies. Meanwhile, Kakashi, when he hears about Sasuke's abduction, would use his intelligence to figure out Orochimaru's location. He could also teach Naruto some new techniques to help in the rescue.
Well, Naruto might use his Nine - Tails chakra to break free. He's a tough one. He could also try to outwit Orochimaru with his ninja skills. Maybe he'd pretend to be unconscious and then surprise Orochimaru when he least expects it.
In a scenario where Orochimaru kidnaps Hinata, the Hyuga clan would surely get involved. They'd be outraged and use all their resources to find her. Orochimaru might be interested in Hinata's Byakugan for his experiments. He could try to extract its power or study it. But Hinata has been trained in the Gentle Fist style, so she might be able to hold her own against Orochimaru's minions for a while. And who knows, Sasuke might also get involved. He has his own history with Orochimaru and might see this as a chance to confront him again, especially if he realizes that an innocent like Hinata is in danger.
In such a fanfiction, Sakura might be used by Orochimaru for his experiments. He could be interested in her chakra or her medical knowledge. Maybe he would try to extract some special power from her or force her to assist him in his unethical research.
In this kind of fanfiction, Sasuke might capture Sakura for various reasons. One possibility is that he wants to use her as a bargaining chip against Naruto. Another could be that he has some kind of misunderstanding and thinks Sakura is a threat to his plans. However, Sakura is not a weak character. She might try to reason with Sasuke during her captivity, appealing to their past friendship. Maybe she could even find a way to escape on her own or with the help of some unexpected allies.
Naruto getting kidnapped by Orochimaru would be a really dangerous situation. Orochimaru could start by putting Naruto in some sort of chakra - suppressing device. This would limit Naruto's ability to use his Nine - Tails power. Then, he might try to implant some of his cursed seals on Naruto, which would give him more control over Naruto. But Naruto has his own allies within himself. The Nine - Tails, despite their rocky relationship, might help Naruto out in this situation. Also, Naruto has the memories of all the people who care about him. He'd draw strength from those memories and keep his hope alive, waiting for the moment when he can break free and return to his friends and the village.
Well, if Sasuke turns into a baby in a fanfiction, one thing that could happen is that his friends would have to take care of him. Naruto, for example, might be really confused at first but then would become super protective. He'd probably try to feed Sasuke all kinds of strange foods that he likes, like ramen, not realizing that babies can't eat that yet. And Sakura would be all motherly, trying to keep Sasuke clean and making sure he's warm.
One possibility is that Naruto and the others would immediately start a search and rescue mission. They would follow Sasuke's tracks and try to figure out his motives. Sakura, on the other hand, might try to reason with Sasuke during the kidnapping. She could remind him of their past friendship and the bonds they once shared.
In this Peter Pan fanfiction scenario where Jane is kidnapped, the situation could be very complex. It could be that the reason behind the kidnapping is related to some power struggle in Neverland. If so, Peter Pan would not only be rescuing Jane but also getting involved in a bigger conflict. He might have to make alliances with some unlikely characters in order to get Jane back. For instance, he could team up with some of Hook's men who also don't want to see the power balance in Neverland disrupted by this kidnapping. And during the rescue, there could be many emotional moments as Peter realizes how important Jane has become to him and to the safety of Neverland as a whole.
One possibility is that Hermione manages to talk some sense into her parents and they release Hedwig. This would require her to explain the importance of Hedwig to Harry and the fact that she is just a normal owl in the wizarding world.
Another scenario could be that Naruto discovers a hidden chamber in the lab. Inside, there are test subjects that Orochimaru was using for his immortality experiments. Naruto feels sympathy for them and tries to rescue them. However, he has to figure out how to deal with the various traps and security measures in the lab first. He might call for help from his friends like Sakura or Kakashi to assist him in this difficult task.
