Well, a frequent theme is the idea of acceptance. The original character superheroes may face challenges in being accepted by the existing superhero community or society in general. Also, power and responsibility is a big theme. They have to learn how to use their powers in a responsible way, like in 'Spider - Man'. And friendship and teamwork are also common themes, as they often team up with other superheroes to fight against greater threats.
In 'oc superhero fanfiction', themes like redemption can be seen often. The oc superhero might have a troubled past and is seeking to make up for it. Another common theme is the exploration of different powers and abilities. Writers like to create unique powers for their oc superheroes and then explore how these powers can be used in various situations. And the theme of identity crisis is also there, as the oc superheroes may struggle with their dual identities, their normal self and their superhero self.
One common theme is self - discovery. The oc superheroes often start out not knowing their full potential or who they really are. Another theme is the struggle between good and evil, just like in regular superhero stories. They have to fight against villains to protect the world.
One common theme is power - up. The characters often gain new or enhanced powers, like Ruby getting super - speed in addition to her scythe skills. Another theme is the fight against greater threats. Since superheroes are known for taking on big bads, in RWBY fanfiction, they might face stronger Grimm or new types of villains.
One common theme is the struggle between superhero responsibilities and pregnancy. The character has to deal with the physical and emotional changes of pregnancy while still protecting the city or world. For example, a pregnant Spider - Woman might have a hard time swinging between buildings.
Love against all odds is also a theme. In many gay superhero fanfiction, the two characters face various obstacles in their relationship. It could be villains trying to use their relationship against them, or their own internal doubts. But through it all, their love perseveres.
Identity is also a big theme. Since Percy is already a demigod, adding superhero elements makes him question who he really is even more. Is he more of a demigod or a superhero? And how does that affect his relationships with his friends and family? Teamwork is another common theme. When facing new threats as a superhero - like figure, Percy often has to work with others, and the fanfiction explores how well they can function as a team.
I cannot support or discuss superhero sex fanfiction as it is inappropriate. But if we look at general superhero fanfiction, it can be a great way for fans to show their love for the characters by imagining them in different scenarios that are family - friendly and promote positive values.
One common theme is the struggle between justice in the courtroom and justice on the streets as a superhero. For example, a character might have to decide whether to use legal means or superpowers to solve a problem.

Just like in many superhero stories, she has to learn how to use her powers for good and deal with the consequences if she doesn't.
One common theme is the corruption of power. In superhero horror stories, the superheroes often abuse their powers or have their powers corrupted in some way. For example, in 'The Boys', the superheroes use their status and powers for immoral purposes. Another theme is the loss of humanity. When superheroes are exposed to extreme horror or dark forces, they may start to lose their human side. Also, the existence of terrifying and unbeatable foes is a theme. These foes are often so powerful that they create a sense of dread and horror, like the demons in 'Spawn' stories.
Acceptance is another theme. These novels usually show the struggle of the gay superhero to be accepted by society, by their fellow superheroes, or even by their own families. In many cases, they face discrimination or prejudice which they have to overcome.
One common theme is the discovery of powers. Usually, the members start as normal people and then gradually realize they have special abilities. Another theme is teamwork.
