One common theme is the exploration of their powers in relation to each other. Since Peter has super speed and Jean has telepathy and telekinesis, fanfics often show how these powers can either complement or clash. For example, Jean might use her telepathy to anticipate Peter's movements during a fight.
One great piece of Peter Maximoff x Jean Grey fanfiction is 'Speed and Telepathy'. It delves into their unique relationship, exploring how Peter's speed and Jean's telepathy could interact in interesting ways during missions and in their personal lives. The author does a wonderful job of capturing their personalities.
Another theme is the idea of outcasts coming together. Jean is a mutant, often seen as different in society, and Peter is a superhero with his own set of problems. Fanfictions usually focus on how they understand and support each other in a world that doesn't always accept them. They form a bond based on their shared experiences of being 'other'.
One popular 'jean grey x peter parker fanfiction' is 'Parallel Universes'. It explores a world where the X - Men and the Avengers cross paths more often, leading to an interesting relationship between Jean Grey and Peter Parker. It has great character development and some exciting action scenes.
One idea could be a crossover where Harry Potter's magical world collides with the mutant abilities of Wanda Maximoff and Jean Grey. They could team up to fight a common enemy that threatens both the wizarding world and the mutant world. Maybe a dark sorcerer is trying to use mutant powers for his own evil deeds and they have to combine their skills to stop him.
It could be really interesting. Imagine Peter's quick - wittedness combined with Jean's powerful telepathy. Their married life might involve Peter using his Spider - Man skills to protect their home and family, while Jean uses her powers to keep their minds safe from threats. They could also have some really fun interactions with other Marvel characters as a married couple.

A possible way to blend the universes is through a shared dream or vision. Jean Grey, with her powerful telepathic abilities, could have a vision that involves Harry Potter and Wanda Maximoff. This vision could be a warning about a great threat that is coming for all of their worlds. Harry and Wanda, initially confused by this strange connection, soon realize that they have to trust Jean and join forces. They then use their combined powers of magic, chaos magic, and telepathy to traverse the boundaries between their universes and face the threat head - on.
