One common theme is their mentorship. Since Harley has his own intelligence and Peter has his Spider - Man skills, they could mentor each other in different ways. Another theme could be team - up stories where they join forces to fight a common villain.
Well, obviously the main characters are Harley Keener and Peter Parker. Harley is known for his intelligence and engineering skills, especially after his interactions with Tony Stark. Peter Parker, of course, is Spider - Man, with his superhuman strength, speed, and that all - important spider - sense.
One interesting storyline could be them teaming up to solve a mystery in their neighborhood that the Avengers overlooked. Maybe it's a small - scale tech - related mystery that Harley's engineering skills and Peter's spider - sense can combine to crack.
Well, perhaps the fanfiction could start with Harley Keener being a big fan of Spider - Man (Peter Parker). He manages to track Peter down somehow, like through some scientific event they both attend. Their meeting could be a bit rocky at first, with Peter being cautious. But then they realize they have a lot in common, especially their love for science and helping people. They might then work together to create some new tech for Peter's superhero activities.
Sure, there are. Some fanfiction authors prefer to write about the characters in a way that adheres to a general - audience - friendly standard. They might explore their relationship as teammates, or how they interact in the superhero world without any sexual or inappropriate elements. You can try different fanfiction communities and use their search and filter options to find such stories.
Peter is often very responsible and has a strong sense of justice. Harley, on the other hand, is more of a free - spirited inventor. Their personalities could complement each other as Peter's sense of purpose could give Harley a new direction for his inventions, while Harley's creativity could help Peter think outside the box in his superhero work.
