It could be that an enemy of theirs devises a plan to humiliate or disable them, which leads to Peter's mpreg. As they navigate through this difficult situation, they discover new aspects of their relationship. For example, Harry might show a more nurturing side that Peter has never seen before, and Peter might find strength in his vulnerability.
The plot could involve a magical or scientific experiment gone wrong that results in Peter's pregnancy. Harry and Peter then have to figure out how to deal with it. They might seek help from other superheroes or scientists who are more understanding of such extraordinary situations.
One possible fanfic could focus on how such an unexpected situation might change the dynamic between Harry and Peter. It could explore the emotional turmoil for both of them. Peter, being the one carrying a child in this mpreg scenario, might struggle with his superhero duties and the new physical and emotional changes. Harry, on the other hand, could be in a state of shock but also feel a sense of protectiveness towards Peter.
A fanfic that stands out is 'Harry and Peter: The Unbreakable Bond'. It focuses on how they support each other. There are many scenes where they have heart - to - heart conversations that give a deep insight into their characters. The author does a great job of staying true to the essence of Peter and Harry in the original stories.
The setting also matters. If it's set in the high - school years, it can explore their teenage angst and growing up together. Or if it's set in the more action - packed parts of their lives as superhero and potential villain, it should capture the intensity of those situations. A good fanfic will blend all these elements - relationship, character development, and setting - to create an engaging story about Peter and Harry.
A good fanfic in this regard would have well - developed characters.

For example, Peter's sense of responsibility might play a role in how he approaches the relationship with Harry.
One interesting plot could be that Peter and Harry discover a parallel universe where their roles are reversed. Harry is the one with superpowers in that universe, and Peter is just a normal person. They could explore how this affects their relationship and what they can learn from each other's experiences in their respective universes.
