One common theme is family. Since family is a big part of 'The Incredibles', in oc fanfiction, new characters might be added to the family dynamic or change the existing family relationships in some ways. For example, an oc might be a long - lost relative.
Another theme is the struggle between normal life and superhero life. OCs might be trying to fit into a world where superheroes exist, or they might be superheroes themselves trying to balance their secret identities with their normal lives. It's a theme that allows for a lot of character growth and interesting conflicts.
One common theme is the clash of different powers. For example, when the Incredibles cross with other superhero groups, there's always the exploration of how their powers compare and contrast.
The most common theme is probably his role as an ordinary person in an extraordinary world. This allows for stories about how he copes with the knowledge of supers and the danger that comes with it. His relationship with the Incredible family, not just Violet, is also a major theme. Some fanfictions might show him as a sort of moral compass for the family, as he represents the normal, non - super values. There are also themes of growth, as he might grow from being a simple high school boy to someone more involved in the complex world of the Incredibles.
Family is a very common theme. Just like in the movie, fanfics often explore the relationships within the Parr family, like the bond between Mr. Incredible and Elastigirl, and how they raise their kids. Another common theme is heroism. Fanfics usually continue the story of the Incredibles as heroes, facing new threats and saving the day.
Some fanfictions also focus on the villains' reactions or potential threats during Helen's pregnancy. It creates a sense of danger and drama, as the family has to protect Helen and the unborn child from possible harm.
One common theme is the clash of different worlds. Since MLP is a magical, pony - filled world and The Incredibles is a super - hero - based world, fanfics often explore how these two very different settings interact. For instance, how the superpowers in The Incredibles compare to the magic in MLP.
One common theme is teamwork. Since both the Avengers and the Incredibles are about groups of heroes, fanfics often explore how they work together. Another theme is power management. The different powers of the characters from both universes are often compared and contrasted.
Character development is another big theme. Fans like to write about how characters like Violet or Dash develop their powers further or how Mr. Incredible deals with getting older while still being a superhero. It gives a chance to expand on the characters in ways that the movies might not have fully explored.
One idea could be an OC with the power to manipulate time joining the Incredibles. They could use their power to prevent disasters or even go back in time to change events that led to Syndrome's rise. Another idea is an OC who is a super - fast healer. They could play a crucial role in patching up the Incredibles after tough battles.
A good OC could be a super with the power of flight and super strength combined. This would make them a really powerful addition to the Incredibles. They could be someone who has been living in hiding and is discovered by the Incredibles.
One idea could be that the OC has a unique power that somehow complements Violet's invisibility and force field powers. For example, the OC can manipulate light in a way that enhances Violet's invisibility, making her undetectable even by advanced technology. They could meet during a mission where their combined powers are needed to defeat a powerful villain.
