Well, perhaps in the fanfiction, Cato kidnaps Katniss because he's been influenced by the Capitol in some way. They might have promised him a great reward if he brings Katniss to them alive. Or it could be that Cato believes Katniss has some secret knowledge that he wants to extract from her by force. This could lead to a tense situation where Katniss has to outwit Cato to escape.
One possible plotline could be that Cato kidnaps Katniss as a strategic move in the Hunger Games. Maybe he thinks he can use her to draw out other tributes or get an advantage over the Careers. Another could be that Cato has some sort of personal vendetta against Katniss that leads him to kidnap her outside of the normal rules of the Games.
Gale might also attempt to rescue Katniss. He's her friend from District 12 and is quite skilled in his own right. He would be furious to hear that Cato has kidnapped Katniss and would likely gather resources and allies to try and save her.
Well, if Cato abuses Katniss in fanfiction, it might change the whole dynamic of the story in an unacceptable way for many. In the original context, they are competitors in a brutal game, but abuse is a whole different level of wrong. This could cause a rift among fans, some who might want to explore darker themes in fanfiction, while others would see it as a desecration of the original characters' relationships. Moreover, it might discourage new fans from engaging with the fanfiction community if they are exposed to such disturbing content.
For Katniss, her focus would change. Instead of just fighting for the districts or her own survival, she'd be fighting for her unborn child. This could make her more strategic in a different way. Cato, on the other hand, would probably have to confront his past actions in the Hunger Games more deeply. He might feel the need to redeem himself in the eyes of Katniss and their future child, which could soften his hard - edged personality.
One possible plotline could be Bella's friends and the Cullens coming together to rescue her. They might plan a stealthy infiltration of Aro's lair, using their unique abilities. For example, Alice could use her visions to anticipate Aro's moves and find the safest way in.
Perhaps the rogue is hired by an evil force to kidnap Lucy. She could be the daughter of an important figure or a person with unique abilities that the evil force wants to use against the good side. As the story progresses, Lucy could try to escape or even try to turn the rogue to her side by appealing to his better nature.
One possible plotline could be Buffy's friends rallying together to rescue her. They might use their unique skills, like Willow's magic, to track down Angelus and his lair.
Another plotline might involve Tom believing that Harry has some hidden power that he can extract or use for his own dark purposes. So, he kidnaps Harry to figure out how to access that power. This could lead to a series of attempts by Tom to break Harry's will and get him to reveal the secret. For example, he might put Harry in a magically sealed room and use various spells to try and force the information out of him. Harry, on the other hand, could be trying to resist and find a way to escape or signal for help.
Well, it could be that Lucy has a misunderstanding. Maybe she overhears something that makes her think Natsu is planning to leave the guild without saying goodbye. So, in a fit of panic and anger, she kidnaps him to get an explanation. Then, as the story progresses, they have a heart - to - heart conversation where the misunderstanding is cleared up. It could also be a situation where Lucy is competing with someone else for Natsu's attention, and she thinks that by kidnapping him, she can have him all to herself for a while and figure out how to make him like her more.
One common theme is the idea of enemies - to - allies. Given their opposing stances in the Hunger Games, many fanfictions explore how they could come to work together or understand each other. Another theme is unrequited love or a forbidden love, as their different districts and roles in the Games make a relationship between them seem impossible in the context of the story's world.
Another plotline might involve Karasu having a personal vendetta against Keiko or someone close to her. He kidnaps her to exact revenge in a more elaborate and drawn - out way. This could lead to a series of events where Keiko tries to outwit Karasu and escape while also uncovering the true reasons behind his actions. And during this process, there could be unexpected alliances and betrayals.
