Your male OC could be a meta - human with the ability to control electricity. He was an ordinary electrician who got caught in a freak accident involving a kryptonite - powered generator. This accident gave him his powers. In your fanfiction, he could start off as a reluctant hero, not fully understanding his powers. He might cross paths with Superman and learn from him how to use his powers for good, eventually becoming a part of the Justice League.
First, give him a unique backstory. For example, he could be a scientist who was experimenting on a new form of energy when an accident occurred, granting him superpowers. Second, define his powers clearly. If he has super strength, explain its limits and how it differs from Superman's. Third, create interesting relationships. He could have a rivalry with an existing villain or a friendship with a less - known hero. This will make the story more engaging.
It depends on personal preference. Some people might like Marvel superheroes more for their diverse powers and relatable characters. Others might prefer DC superheroes for their classic and iconic status.
A lot of people also like the fanfictions that explore the relationship between Wonder Woman and other heroes in a more in - depth way. For example, a story where she has to train a new generation of female heroes. It's inspiring and showcases her leadership skills.
Well, perhaps in an alternate universe where the Naruto world and DC universe somehow cross paths. Naruto, being a father, might have been introduced to DC superhero stories by his kids or maybe he stumbled upon some DC comics during his travels. He could be drawn to the complex characters and their moral dilemmas in the DC universe.
Plastic Man's origin in fanfiction often varies. In some, he might be an experiment gone wrong in a scientific facility. His abilities include extreme elasticity, which allows him to stretch his body into various shapes and sizes. He can also mold himself into objects, like a key to unlock a door or a parachute to slow his fall.
Friendship and cooperation is also a major theme. Many fanfictions depict Naruto forming bonds with DC superheroes. They might start off as strangers or even enemies but end up working together to face a common threat. This shows how characters from two very different universes can come together for a greater good.
DC Comics has a vast array of superheroes. There are so many that it's almost impossible to put a specific number on it. However, it's safe to say there are many hundreds, each with their own unique powers and storylines.
