Well, if Peter Parker is a demigod in fanfiction, his origin story could be tweaked. Instead of just being bitten by a radioactive spider, it could be a part of a grander plan by the gods. His family could have a hidden connection to the divine world. His moral compass, which is already strong, could be influenced by demigod ethics. He might have to deal with other demigods who are either his allies or enemies, and this would add a whole new layer of complexity to his character and the stories he's in.
One way could be to combine Peter's spider - powers with demigod traits. For example, he might gain enhanced strength not just from the spider bite but also from his demigod heritage. Maybe his 'spidey - sense' could be related to some sort of premonition ability that demigods have. He could also interact with other mythological creatures in the Marvel universe, like facing off against a hydra - like creature in a more myth - inspired way.
One way is through internal monologues. Peter can have long internal conversations with himself, debating where to go on the 'date', what to wear, etc. This would show his different aspects interacting.
In this fanfiction, Peter could save the Avengers in a more emotional way. Suppose the Avengers are facing a powerful villain who is using mind - control on them. Peter, being the friendly neighborhood Spider - Man, has a strong will. He manages to break through the mind - control on one of the Avengers first, like Captain America. Then together, they work to free the rest of the team and defeat the villain.
In fanfiction, their relationship could start with a misunderstanding. For example, Peter might accidentally interfere with one of Captain Marvel's missions thinking he's helping. This could lead to an initial tension. But as they talk it out, they realize they have a common goal of protecting the innocent. They then start to trust each other more and more, and eventually become friends who rely on each other's unique skills in battles.
Peter can be developed by showing his struggle to balance his normal student life in the Zoom class with his superhero duties. For example, he might be constantly distracted during class because he's worried about the next bad guy he has to fight. Also, his interactions with classmates during Zoom calls can show his growth as a person. If he's usually shy but has to speak up to defend someone from a bully during a call, it shows his courage.
Their relationship can be developed through shared challenges. For instance, if they both get caught in a dangerous situation not related to Peter's Spider - Man activities, like being trapped in an abandoned building during an earthquake. They have to rely on each other to survive, which breaks down some of the barriers between them.
Peter's relationships can also be developed. His friends could come to visit him when he's sick. He might be more open with them about his insecurities as Spider - Man. And his enemies might take advantage of his weakened state, which forces him to grow and find new ways to defend himself even when he's not at his best.
Peter Parker could be developed by emphasizing his new - found spider - like curiosity. He might start exploring the city in a different way, noticing small details and hidden corners that he previously overlooked. This could lead to him discovering new threats or helping people in unexpected ways.
One way it could be developed is through Tony Stark taking Peter under his wing early on. Maybe Peter's parents were somehow connected to Stark Industries. Tony could discover Peter's intelligence and potential, and start mentoring him like a father figure. This could lead to a strong bond between them, with Tony providing Peter with resources and guidance in both his personal life and his superhero activities.
One idea could be that Peter Parker discovers an Infinity Stone by accident. Maybe he's on a routine patrol as Spider - Man in New York and stumbles upon a strange energy source that turns out to be an Infinity Stone. This discovery could put him in the crosshairs of many powerful villains who want the stone for themselves.
In some fanfictions, the umbrella could have a more symbolic meaning. For example, it could represent Peter's attempt to lead a normal life. Just as an umbrella shelters from the rain, Peter might see it as a way to shield himself from his superhero duties for a short time.
