No, it's not common. Fanfiction writers tend to focus on more positive or well - explored aspects of the source material. Kidnapping is a rather dark and often complex theme to handle. So, while there might be the occasional 'gon kidnapped' fanfiction, it's not something you'll find in large numbers compared to more common fanfiction themes like friendship or love within the fandom. Also, different fandoms have different sensitivities towards such dark themes, which can also affect the prevalence of such fanfictions.
I'm not aware of any specific 'gon kidnapped' fanfictions. Fanfiction can be a very niche area, and often such specific themes might not be widely known or easily accessible. It's also important to note that some fanfictions may involve disturbing or inappropriate content, so one should be cautious when exploring this area.
Papyrus can also be a victim of kidnapping in fanfictions. His naive and friendly nature makes him an easy target in some stories. His kidnapping could lead to Sans going on a desperate search for him, which would involve a lot of action and emotional moments as Sans tries to rescue his brother.
Gon would probably be angry at first. He has a strong sense of justice and being kidnapped against his will would surely make him mad. He'd try to fight back immediately if he had the chance.
One common theme is the theme of rescue. The story often revolves around her team or loved ones trying to find and save her. Another theme could be the mystery behind the kidnapping. Who kidnapped her and why? There might also be a theme of Kensi's inner strength as she tries to survive in the captivity.
One common theme is identity. Gon has to figure out who he is while being raised by a group that has a very different moral code. Another theme is loyalty. He has to decide where his loyalties lie, with the Phantom Troupe or with his own sense of right and wrong.
It could also be part of Hisoka's game - playing with Gon's friends and allies. By kidnapping Gon, he can draw out others like Killua. Hisoka enjoys creating chaos and seeing how people react. This would be his way of setting up a more interesting and dangerous situation.
A common plot point is the immediate reaction of his friends. They usually go into a state of shock and then quickly shift to determination to rescue him. Another is the discovery of clues. There might be a piece of clothing left behind or a strange symbol at the kidnapping scene. Also, there could be some sort of ransom demand, which would add more complexity to the story.
One common plot might be a 'rescue' plot. For example, the other members of Stray Kids find out that one of them has been kidnapped and they go on an elaborate adventure to save their friend. Another could be a mystery plot where the kidnapper has some mysterious motives related to the group's fame or a secret from their past.
One common plot element is the rescue mission. His friends or family, like Batman or the Titans, will often start a search to find him. Another element could be Dick Grayson trying to escape on his own using his combat skills and wits. Sometimes, there might be a mystery aspect, such as why he was kidnapped in the first place and what the kidnapper really wants from him.
Often, a plot twist is that one of the twins is actually in on the kidnapping for some self - serving reason. This could be to gain attention or to get a share of a large inheritance. It completely changes the dynamic as the other twin has to deal with the betrayal on top of the kidnapping situation. It also adds an element of mystery as to why the twin would do such a thing.
