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.
If Orochimaru kidnaps Hinata, it would be a very dangerous situation. Orochimaru is known for his cruel experiments and thirst for power. Hinata, on the other hand, is a kind - hearted and somewhat shy girl. However, she has hidden strength. Her friends from the Hidden Leaf Village would not abandon her. They'd start a search immediately. Konohamaru might even try to prove himself by joining the rescue mission. And the senseis like Kakashi would also be involved in planning the rescue. There could be a lot of twists and turns in this fanfiction. Maybe Orochimaru has an ulterior motive that is not just related to Hinata's Byakugan, like using her as bait to lure out other powerful ninjas from the village.
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.
Perhaps Madara has some ulterior motives for kidnapping Hinata. He might want to use her as a bargaining chip against the Hidden Leaf Village. Or he could be interested in her unique abilities. In that case, the Hidden Leaf would have to decide whether to meet Madara's demands or try to outwit him to get Hinata back safely.
In a fanfiction where Naruto and Hinata join Orochimaru, one possibility is that they are forced into it. Maybe Orochimaru has some kind of leverage over Konoha that makes them comply. Naruto, being the head - strong character he is, would likely be constantly looking for a way to escape and take Hinata with him. Hinata, on the other hand, would probably be more reserved and observant, trying to find Orochimaru's weaknesses.
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 a fanfiction where Esdeath kidnaps Tatsumi, one possibility is that she tries to force him to join her side. She might use various means like threats against his friends or promises of power. Tatsumi, being a hero at heart, would likely resist. He could try to escape while also trying to figure out Esdeath's weaknesses to defeat her later.
Well, in a typical scenario, Sonic would probably rush to save Tails. He'd use his super speed to track Eggman's lair. Maybe he'd find some clues along the way, like a piece of Tails' fur or a gadget that Eggman accidentally dropped. Then, Sonic would face off against Eggman's badniks, defeat them one by one, and finally reach Tails. He'd free Tails and they'd escape together, with Eggman vowing revenge as usual.
Another scenario could be that Naraku has some ulterior motive for kidnapping Kagome. Maybe he wants to use her spiritual powers for his own evil purposes. He could try to corrupt her or force her to use her powers against Inuyasha and the others. But Kagome would resist with all her might, and her love for Inuyasha and her friends would give her the strength to hold out until they come to her rescue.
Well, one possibility is that Elena's friends would immediately start a search party. Damon, for instance, would be furious and stop at nothing to find her. He might enlist the help of Stefan and Bonnie. They could use Bonnie's magic to try and track Klaus' whereabouts.
Another aspect could be the emotional turmoil for the other Avengers. They would surely be scrambling to find Tony. Captain America might feel especially guilty, considering their past differences. The team would have to put aside their differences completely to rescue Tony. They might start by gathering intel on Thanos' whereabouts and formulating a plan that involves their unique skills. For example, Black Widow could use her espionage skills to infiltrate Thanos' base, while Thor could provide the brute force needed in a direct confrontation.
Well, one possibility is that Goku's friends would immediately start a search and rescue mission. Vegeta, being his rival but also an ally, would probably be at the forefront. He'd be furious that Broly dared to kidnap Goku. They'd likely track Broly's energy signature to wherever he's taken Goku. Another thing could be that Goku, while kidnapped, tries to reason with Broly. Maybe he discovers that Broly has some deeper issues or motives for the kidnapping that could potentially be resolved through conversation.
