Sure. There's one where Peter Parker accidentally gets caught in a teleportation experiment by the Fantastic Four. He ends up in a dimension where the laws of physics are different. The Fantastic Four have to enter this dimension too to rescue him. Along the way, they find out that an old enemy of the Fantastic Four has taken control of this dimension and plans to use it as a base to invade their own world.
There is a fanfiction where Peter Parker's identity as Spider - Man is revealed to the Fantastic Four in a rather embarrassing way. But instead of being angry or judgmental, they offer to train him further. In the process, they discover a connection between the radiation that gave Peter his powers and the cosmic rays that affected the Fantastic Four. This connection leads them to a hidden power source that a group of villains is also after.
There's a fanfiction where Peter Parker is stuck upside down in an alternate dimension. In this dimension, everything is topsy - turvy, and he has to find a way back to his own world while also dealing with an evil version of himself. It's really unique as it plays with the concept of identity and the idea of being in an unfamiliar and inverted world.
One interesting fanfiction could be about Peter Parker teaming up with the Fantastic Four to face a new super - villain that neither could handle alone. Maybe a villain who has the ability to manipulate time and space, and they have to combine their powers and intellects to stop this threat.
There are many great Peter Parker fanfictions out there. You could try 'The Spectacular Spider - Boy' which has a great take on Peter's early days as Spider - Man. Another one is 'Peter Parker: The College Years' which focuses on his life in college while still being a superhero. And 'Spider - Man: A New Perspective' gives a fresh look at his relationships with his friends and family.
I'm not sure of a specific 'Peter Parker is evil' fanfiction off the top of my head. But you could try searching on fanfiction websites like Archive of Our Own. There might be some works there that explore this dark concept of Peter Parker.
A unique 'Peter Pan and Hook' fanfiction is the one where Hook and Peter are brothers separated at birth. They don't know about their relation until certain events unfold in Neverland. This changes the whole nature of their enmity and the way they interact with each other and the other characters in the story.
Sure. In certain fanfictions, Peter has the power of invisibility. This gives him an edge in stealth operations and sneaking up on villains. It's a really cool addition to his existing powers.
A plot could revolve around a corrupt foster care system that Peter uncovers. As Spider - Man, he tries to expose the people involved and at the same time, he finds a family within the foster care system. Maybe there's a group of kids who look up to him and he starts to feel a sense of responsibility towards them, not just as Spider - Man but also as Peter Parker.
Another aspect is the reaction of the other characters. His friends like Ned and MJ, or even Aunt May, have to deal with this new situation. They might have to protect him, or figure out a way to bring him back. It often leads to some really interesting character development for them as well. In a lot of these fics, Ned shows his loyalty and intelligence in trying to solve the mystery of Peter's hibernation.
Well, one unique feature is the blend of two different genres. You have the superhero genre of Spider - Man and then the fantasy genre of magic. It creates a whole new world of possibilities for the story. For example, Peter can use magic to enhance his web - slinging or to create new types of attacks against villains.
Well, in some fanfictions, Peter Parker is a blogger. He uses his blog to report on not just Spider - Man but also other superhero - related events and social issues in his city. It's a modern take on his role as an information spreader, different from the traditional newspaper photographer role.
