One possible reason could be revenge. Maybe someone has a grudge against the Rifleman and decides to target his son Mark. Another reason might be for ransom. The kidnappers could think that the Rifleman, being a well - known figure, would pay a large sum to get his son back.
Well, in some fanfictions, Mark could be kidnapped because he has some information that the kidnappers want. It could be something he overheard or something that makes him a valuable target. Also, it might be a case of mistaken identity. The kidnappers might think Mark is someone else who is important to their plans.
Well, it's somewhat common. In such fanfictions, often the focus is on the rescue mission. The story might show the Rifleman's skills and determination as he tries to find Mark. Another aspect could be Mark's own growth during the ordeal. He might show courage or resourcefulness while in captivity, which adds depth to his character. And usually, there's a build - up of suspense throughout the story until the moment of rescue.
Orochimaru could be interested in Sakura's chakra. The curse mark might be a way to manipulate or study her chakra in some way. Also, he might want to use her as a pawn against Naruto or Sasuke, knowing that Sakura is close to them.
It could be the result of a dark wizard's experiment gone wrong. Maybe some dark wizard was trying to create a new form of dark magic, and Harry accidentally got caught in the crossfire and ended up with the curse mark.
In some fanfictions, sans might be made to kidnap for various reasons. One could be that he's misinterpreted a situation. Maybe he thinks the kidnapped person has some crucial information that could save his world or his friends. Another reason could be that he's been corrupted in some way, perhaps by an external evil force that's manipulating his actions.
One possible reason could be that Esmeraude wants to use Haruka as a bargaining chip. Maybe she plans to exchange Haruka for something valuable, like a powerful crystal or a secret from the Sailor Guardians. Haruka is a strong and important character, so she would be a valuable hostage.
One reason could be his underlying sense of good. Despite his family's alignment with the Dark side, Draco might have a moral compass that rebels against the evil associated with the Dark Mark. He may have seen the destruction and pain it causes and doesn't want to be part of it.
Another plot could involve Harry being tricked into taking the Dark Mark. He might think he's doing something else, like a magical experiment or a ritual to save someone. But it turns out it was a setup by a dark wizard. Harry then has to face the consequences, not only the physical and magical changes brought by the Dark Mark but also the change in how others perceive him, especially his friends who might be shocked and scared.
Well, in some fanfictions, it might be to test the loyalty of his friends and allies. If Luke is kidnapped, it forces characters like Han Solo, Leia, or other Jedi to come to his aid. It could also be to explore different timelines or alternate universes where Luke's kidnapping sets off a chain of events that are different from the original 'Star Wars' story. Maybe it's a way to bring in elements from other science - fiction concepts, like time travel or parallel dimensions, in relation to his kidnapping.
One possible motive could be to use Miko as a bargaining chip. Maybe the kidnappers want to exchange her for some valuable object or information within the Transformers' world. For example, they might be after a powerful Energon source or a secret Autobot technology.
One possible motive could be ransom. Maybe someone wants a large sum of money from Philip's family or friends. Another could be revenge. Perhaps Philip has unknowingly wronged someone in the fanfiction world, and this is their way of getting back at him.
