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.
One interesting idea could be exploring Peter Parker's self - discovery. By 'dating himself', he might learn more about his own needs and desires that he's overlooked while being Spider - Man. It could also be a comical take on his dual identity, like he has different 'dating' experiences as Peter and as Spider - Man.
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.
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.
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.
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 could develop a deeper sense of patience during hibernation. When he wakes, he's more calm and collected in dealing with his enemies. For example, instead of rushing into a fight, he might take time to strategize. Another aspect is that he could gain new moral insights. Maybe in his hibernation - induced dreams, he faces ethical dilemmas that change his view on using his powers. So, when he returns, he's more cautious about how he uses his strength.
To develop the characters, consider their powers and how they affect their personalities. If a soulmate has the power of telepathy, they might be more empathetic but also struggle with privacy issues. Peter, being the central character, can help them navigate these challenges. Additionally, their character development can be tied to the story's themes. If the theme is about acceptance, then the characters need to learn to accept themselves and each other. They can start off with insecurities related to their identity as soulmates of Peter Parker. But as the story progresses, they can overcome these insecurities and become more confident individuals, which in turn enriches their relationships with Peter and each other.
For Peter Parker, you can show his growth in fanfiction by having him face more complex moral dilemmas. Maybe he has to decide whether to side with Frank Castle's extreme methods in a situation where the law fails. This would test his own beliefs about justice. For Frank Castle, you could explore his softer side. Maybe Peter's idealism starts to rub off on him, and he begins to question his one - man - army approach.
In fanfiction, a great way to develop their relationship is by having them teach each other new things. Peter could show Gwen some new web - slinging techniques he's developed, and Gwen could teach Peter some of her unique combat moves. This mutual learning experience can bring them closer together. Also, if they get injured during a fight, taking care of each other can be a strong relationship - building moment.
