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.
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.
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.
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.
Some specialized superhero or DC Comics fan communities may also host or recommend Clark x Bruce yaoi fanfiction. These communities often have members who are really into specific pairings and can point you in the right direction. For example, on Reddit, there might be relevant subreddits where fans share and discuss such fanfictions.
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.
One common theme could be the clash of two very different worlds. Bruce Wayne from the DC universe and Harry Potter from the wizarding world have distinct backgrounds and cultures. Another theme might be the exploration of their powers and how they interact with each other in a relationship context.
One popular place to find such fanfiction is Archive of Our Own (AO3). Just search for 'Clark Kent x Bruce Wayne' on the site and you'll get a list of relevant stories. However, the availability and popularity of specific fanfictions can change over time.
Friendship is another key theme. Their relationship was crucial for the success of the expedition, and fanfictions like to explore how deep their friendship really was, sometimes even hinting at a more profound connection.
The theme of power is quite common too. Clark has his superpowers and Lex has his wealth and influence. Fanfictions often explore how these different forms of power create tension between them. Also, the theme of redemption sometimes comes up, like whether Lex can be redeemed through his relationship with Clark.
