In a fanfiction about Peter Parker being kidnapped as a child, it might focus on how his family and friends reacted. Aunt May would be devastated. His friends like Ned might try to find him on their own, getting into all sorts of trouble in the process. It could also show Peter's early display of his spider - like abilities as he tries to escape from his captors.
Peter would likely be defiant. He has a strong moral compass and wouldn't easily give in to Osborn's demands. He'd probably try to find a way to escape right away, using his spider - abilities like climbing walls and his super strength to break free from any restraints.
Maybe Doctor Octopus. He has always been obsessed with power and knowledge. He might kidnap Peter to figure out the secret behind his spider - powers. He could think that by studying Peter, he can enhance his own mechanical arms or gain some new form of power that would make him the most feared villain in the city.
The Green Goblin is a likely kidnapper. He's always had a vendetta against Spider - Man. Also, Doctor Octopus could be a candidate. His mechanical arms and his intelligence make him a formidable foe who might kidnap Peter for his own devious experiments. Another one could be the Vulture, who might see Peter as a valuable asset to sell to the highest bidder in the criminal underworld.
A fanfiction might involve Peter Parker and Tony Stark being kidnapped during a mission. They are held in a high - security facility. While kidnapped, Tony uses his wits to analyze the security system, and Peter uses his enhanced senses to gather information about their captors. Eventually, they manage to outsmart their captors and escape.
One possible plotline could be that Peter is kidnapped by a group of villains who want to use his spider - abilities for their own evil plans. They might try to force him to create some sort of super - weapon using his web - shooting and super - strength. Another plotline could be that a mad scientist kidnaps Peter to study his unique DNA and how it gives him his powers. Maybe the scientist wants to replicate the powers for himself or sell the formula to the highest bidder.
A fanfiction could show Peter being kidnapped by a criminal mastermind who wants to use him as leverage against Spider - Man in the future. Peter, as a child, would have to find a way to escape and also figure out how to stop this person from ever coming after him again. It could involve him making new friends among other kidnapped kids who help him in his escape plan.
One common plot twist could be that the kidnappers turn out to be working for an old enemy of Spider - Man who wants to use Peter to get to him. Another could be that the person behind the kidnapping is someone Peter thought he could trust, like a fellow student or a neighbor who has a hidden agenda. Maybe there's also a plot twist where Peter discovers he has a new power during the kidnapping situation that helps him escape.
Well, one possibility is that Spider - Man's friends, like Ned and MJ, would quickly realize he's missing. They might start their own investigation, using Ned's tech - savvy skills to try and track Peter. Maybe they'd find some clues that lead them to one of Osborn's secret lairs. Another thing could be that Peter manages to break free on his own using his spider - powers and his wits. He could then turn the tables on Osborn and expose his evil plans to the public.
Maybe it's an old enemy of Peter's who has found out about his friendship with Flash. For example, someone from Oscorp who wants to take revenge on Peter for foiling their evil plans in the past and figures kidnapping Flash will draw Peter out.
