Survival is a major theme. Stiles has to find ways to endure the torture and escape his captors. Another theme is the psychological impact. The trauma he experiences changes his perspective and relationships.
One common theme is the discovery of hidden strength. Stiles, in these stories, often discovers new aspects of himself while facing such extreme situations. Also, the theme of loyalty is present, as his friends try to rescue him.
There's a fanfiction where Stiles is kidnapped by a supernatural being and tortured in a hidden lair. It focuses on his attempts to escape and the friendships that help him through it. The author does an excellent job of building tension throughout the story.
Often, it's the hunters who turn out to be the antagonists. Hunters who don't believe in the good of the supernatural beings associated with Stiles. They might think that by kidnapping Stiles, they can get information about the other supernaturals and eliminate them. Also, some fanfictions feature a deranged human scientist who wants to study Stiles because he seems to be a key to understanding the supernatural world, but they go about it in a very unethical way by kidnapping him.
Well, sometimes in these types of fanfictions, a plot twist can be that Stiles finds out Gerard is related to him in some unexpected way. This could completely change the dynamic of their relationship. Maybe Gerard is his long - lost relative, and this revelation makes Gerard have second thoughts about his actions. Or, there could be a plot twist where the place where Stiles is kidnapped has some sort of magical property that either aids or hinders his escape. For instance, it could be a place that nullifies certain supernatural powers, making it more difficult for Stiles to use his usual means of getting out of trouble.
One common theme is Stiles' growth. He often starts as the human in a supernatural world and has to adapt and become stronger. Another theme is friendship. His relationships with Scott, Lydia, and the others are always explored. For example, in many fanfictions, his loyalty to Scott is tested and strengthened.
No. Kidnapping and torture are extremely serious and immoral acts in real life. Fanfiction that involves such themes can be disturbing and may have a negative impact on the readers' mental state. It also goes against basic moral and ethical values.
Sometimes, the plot twist is that Stiles is actually in on the kidnapping in a way. Maybe he's trying to protect his friends from a greater danger by faking his own kidnapping. So all the while his friends are searching for him, he's actually on a secret mission of his own, which is revealed later in the story and makes for a really interesting read.
One common trope could be the rescue mission. After Naruto is kidnapped and tortured, his friends or allies would likely embark on a dangerous rescue mission. Another might be the transformation of Naruto's character. The torture could potentially lead to him becoming more jaded or having a new perspective on life. Also, there could be the trope of the villain's motives. The kidnapper might have some convoluted reason for targeting Naruto, like trying to gain power through his unique abilities or to send a message to the Hidden Leaf Village.
One common element is the sense of isolation. Victims are often cut off from the outside world, like in the case of Jaycee Dugard who was held in a secluded compound. Another element is the power imbalance. The kidnappers have complete control over the victims, which they use to torture them both physically and mentally.
One common theme is the idea of vulnerability. Stiles is often shown as being strong - willed, but when he's hurt, that vulnerability comes to the surface. It makes the other characters, especially his friends, step up and show their protective sides.
A less obvious but still present theme is self - discovery. Both characters are often on a journey of understanding themselves better. In the context of their relationship in fanfiction, this self - discovery can be influenced by their interactions with each other. For example, Peter might learn more about his capacity for good through his friendship with Stiles, and Stiles might discover new aspects of his own abilities or personality when dealing with Peter.
