First of all, it's inappropriate. Spider - Man stands for justice and helping others, not for unethical behavior like peeping. This kind of fanfiction can give a wrong impression of the character. Moreover, it might not be acceptable in the eyes of many fans who want to see the character in a positive light. Fanfiction should enhance the character, not degrade it with such improper themes.
I'm not really into fanfiction about 'peeping' in relation to Spider - Man as it can be inappropriate. However, there are many great Spider - Man fanfictions that focus on his heroic deeds, his relationships with other characters like Mary Jane or Ned. You can find these on fanfiction platforms by searching for positive and heroic - themed Spider - Man stories.
One unique storyline could be that Spider - Man is mistaken for a peeping tom by a neighbor while he's actually just checking on an elderly person who lives alone in the building. The neighbor calls the police, and Spider - Man has to prove his innocence while also dealing with the bad guys who are planning a heist in the neighborhood. Another could be that a villain tries to frame Spider - Man as a peeping tom to ruin his reputation, and Spider - Man has to clear his name.
Well, while the term 'peeping tom' has a rather negative connotation, in the context of fanfiction, it could be reimagined. There could be stories where Spider - Man is in a situation that seems like he's peeping but in reality, he's using his powers to gather information for the greater good. It's not easy to find these types of stories among the vast amount of fanfiction, but they might exist on platforms like Archive of Our Own or FanFiction.net if you look closely enough.
In Spider - Man fanfiction, one interesting aspect is the exploration of different relationships. For example, new friendships or romances for Peter Parker that might not be in the original comics or movies. It could also show how he deals with different villains in unique scenarios, like facing a more powerful version of the Green Goblin.
One common theme is the exploration of Spider Man's dual identity. Fanfictions often focus on how Peter Parker manages to balance his normal life with his superhero responsibilities. Another theme is the relationships he has, whether it's with his love interests like Mary Jane or his friends and family.
One problem is the inappropriateness. It combines two elements in a sexual context that is not only abnormal but also likely to be offensive to most people. Another issue is that it doesn't conform to the general standards of good literature or fan - created works which usually focus on positive themes like friendship, adventure, etc.
You could have a character use some sort of special weapon or gadget designed to deal with spiders. Maybe a high-tech spray or a laser device.
In some fanfictions, Ultron might team up with one of Spider - Man's villains, like the Green Goblin. They could create a plan to take over New York. Spider - Man would then have to face this powerful alliance. He might seek help from other superheroes he's associated with, like Iron Man or Daredevil, to combat this new threat.
In fanfiction, if Spider - Man becomes a spider, it would be a total transformation. His identity as Peter Parker would be almost completely lost. He would have to adapt to a new body structure. His suit might not fit him anymore, and he would need to find a new way to protect himself. Also, his enemies might not recognize him, which could be both an advantage and a disadvantage in his battles.
The romance in fanfiction usually has a touch of the extraordinary. Their relationship is not like an ordinary couple's. They can communicate in ways that normal people can't, like using their spider - senses. And they might have special moments that are only possible because of their powers, such as a web - swinging date. These aspects make their romance in fanfiction really unique and appealing.
