The theme of identity is quite prevalent too. They are both Kryptonian but have different upbringings and experiences on Earth. Fanfictions may explore how they reconcile their Kryptonian identity with their Earth - based personas. For example, how Superman's more traditional American values mesh with Supergirl's more recent arrival and different perspective. This exploration of identity can add depth to their relationship and the stories.
Love and romance can also be a common theme, although it can be a bit controversial given their family relation in the official lore. However, in fanfiction, authors often re - imagine their relationship in a way that allows for a romantic connection. Also, the theme of self - discovery is present. They both are constantly learning about their powers and themselves, and fanfictions sometimes focus on how they help each other in this journey of self - discovery.
The theme of overcoming differences also pops up a lot. They are from different fictional universes, with different power systems, languages, and ways of life. Fanfictions often center around how they bridge these gaps to become allies or more. They might face challenges like misunderstandings at first due to their different ways of communication, but eventually find common ground through shared values like protecting the innocent.
One common theme is the clash of ideologies. Supergirl, with her more traditional superhero values of hope and justice, often clashes with Red Hood's grittier, more violent approach to protecting the city. This creates a lot of tension and interesting character interactions.
One common theme is the power dynamic. Since Supergirl has superpowers, it often explores how the male reader interacts with her in that context. For example, he might be in awe of her powers or help her use them in a different way.
One common theme is the struggle of Superman to balance his heroic duties with his relationships in the harem. Another theme is the different personalities of the female characters in the harem and how they interact with Superman.
Some fanfictions explore the idea of a power struggle between them. Even though Superman is more experienced, Superboy might have some unique powers or a different way of thinking. This can lead to some interesting conflicts and how they resolve them, while still maintaining their bond as heroes in the DC universe.
The theme of self - discovery is also prevalent. Supergirl may be on a journey to find out who she really is, not just as a superhero but as a person. This can include exploring her likes, dislikes, and her place in the universe.
One common theme is the crossover of powers. Since Supergirl has superhuman abilities and the Mass Effect universe has its own unique powers and biotics, stories often explore how these powers interact. For example, how Supergirl's flight might be different in a Mass Effect world with different gravity rules.
A theme of redemption can also be found in some 'j'onn x oc supergirl fanfiction'. Maybe the OC has a dark past or made some mistakes before coming into the Supergirl universe. J'onn, with his sense of justice and compassion, helps the OC to atone for their past deeds. Also, the theme of family is sometimes explored. J'onn, who has lost his own family, may see the OC as a new family member or someone to protect, and this relationship can be a central part of the story.
One common theme is the clash of ideologies. Superman with his more idealistic view and Bruce Wayne with his darker, more practical approach often have differences to work through. For example, in many fics, they argue about how to deal with villains, Superman preferring rehabilitation while Bruce is more about incarceration.
Often, there is the theme of isolation. Batman may find himself isolated as Superman's yandere behavior drives others away or makes it difficult for Batman to have normal relationships. Also, a theme of self - discovery can be present. Batman has to re - evaluate his relationship with Superman and his own limits when faced with this new, intense version of his friend.
