Love can be a theme as well. Sometimes it's romantic love, with Bruce Clark having a love interest. Other times it's platonic love, like the love between friends or family. These themes help to make the fanfics more relatable and interesting to readers.
Self - discovery is also a popular theme. In many fanfics, Bruce Clark is on a journey to find out more about himself, his powers (if he has any), or his place in the world. And of course, there's the theme of adventure. He's often going on exciting adventures, exploring new places or solving mysteries.
The theme of trust is very prominent. Given their different backgrounds and methods, it takes time for them to fully trust each other in fanfics. And then there's the theme of love - whether it's platonic or romantic. Their relationship is often a central focus, with how they support and care for each other in different situations, be it in a fight against a powerful villain or just in their daily lives.
The theme of secrecy and revelation is also quite common. They are superheroes, and a pregnancy in this situation can be a big secret to keep. So, fanfictions often play with how they hide it from others, and when and how they finally reveal it. It adds an element of suspense and drama to the story.
Another theme is the power dynamics. Given that both Clark and Bruce have their own unique powers and resources in the DC universe, fanfictions might play with how these powers interact in the context of their relationship. It could be about one protecting the other or them working together in a new way.
The theme of secrecy and trust also pops up a lot. Clark has his secret identity as Superman, and Bruce is Batman. They have to learn to trust each other with their true selves. Fanfictions often explore how they come to terms with this, like in the story where Bruce discovers Clark's identity and has to decide whether to keep his trust or expose him. This creates a lot of tension and drama in the stories.
One common theme is identity. Since Clark has lost his memory, he has to rediscover who he is, both as Clark Kent and as Superman. This often leads to a lot of self - exploration.
One common theme is the contrast between their personalities. Clark is often seen as the more open and friendly one, while Bruce is the brooding and mysterious type. Their relationship in these fanfictions usually explores how they balance each other out.
There are fanfics that focus on their different ideologies. For example, 'Clash of Titans' where Bruce's more brooding and gritty approach clashes with Clark's idealistic view, but they still find common ground. These kinds of stories are really interesting as they show the complexity of their relationship.
A theme that is often explored is the clash of their worlds. Bruce is from Gotham, a dark and gritty place, while Diana comes from the idyllic Themyscira. Fanfics might look at how these two different backgrounds impact their relationship. For example, how Diana's more idealistic view of the world might conflict with Bruce's more cynical one, and how they overcome these differences.
One common theme is the struggle between good and evil. Since Bruce is often seen as a force for good and Jeremiah can be a bit more morally ambiguous, this creates a lot of tension in the stories.
Another theme is the exploration of their dual identities. Bruce as Batman and Selina as Catwoman. Fanfics may delve into how they balance their personal feelings with their masked personas and how their identities affect their relationship. For example, there could be stories about how they keep their relationship a secret from the rest of Gotham while still being true to themselves.
