One plot idea could be Pietro and Wanda exploring their powers further in a world that fears them. They might have to team up with other X - Men to face a new, powerful mutant - hating organization. Another could be a story set in an alternate universe where they have different relationships with the other mutants. For example, Pietro could be more of a loner and Wanda has to convince him to work with the team.
In fanfiction, their relationship could be developed further by exploring their different views on the use of their powers. Pietro might be more impulsive and want to use his speed for quick solutions, while Wanda is more cautious. Through arguments and reconciliations over this, their relationship can grow. Also, having them experience personal growth separately but then coming back together and realizing how much they've changed and still care for each other can be a great way to develop their relationship.
Clint could start by providing a safe environment for them to practice. He might find an isolated place where they can freely use their powers without fear of being discovered or causing harm. He could also introduce them to some of his friends who have knowledge about powers or combat skills, like Natasha, who could offer different perspectives on how to control and enhance their abilities.
One common theme is speed. Given Pietro's super - speed ability, many fanfictions explore the limits and implications of his speed. Another theme is family, as his relationship with his sister Wanda is often a central part of the stories.
In some fanfictions, the OC could have a power that is the opposite of Pietro's in some way. For example, if Pietro is all about speed, the OC could have a power related to slowness or time - stopping. This contrast would create interesting dynamics. They might start off as rivals, constantly challenging each other. But then, they realize that together they can be a great team, like two sides of a coin. Eventually, their relationship could evolve into something deeper as they learn to complement each other.
Wanda and Pietro did not date in the comics. Their connection is that of brother and sister, and the storyline doesn't depict them in a romantic relationship.
Sure. One popular x men pietro fanfiction is 'Pietro's New Path'. It explores Pietro's character development outside of the main X - Men storylines. Another great one could be 'Pietro and the Time Anomaly', which involves Pietro getting caught in a time - related mystery within the X - Men universe.
In the comics, Wanda and Pietro did not sleep together. Their relationship was more focused on their superhero activities and family dynamics rather than anything of that nature.
