Another theme is the idea of teamwork. Given their different powers and approaches, fanfictions usually show how they can combine their skills to fight crime in Gotham. It could be Plastic Man using his stretching abilities to reach places Batman can't, while Batman provides the strategic planning.
A common theme is the contrast between their personalities. Batman is all about discipline and control, while Plastic Man is more carefree and flexible in every sense. Writers often explore how these two extremes interact.
The theme of redemption can also be found. Sometimes Plastic Man is portrayed as a bit of a wild card or even a former criminal. Working with Batman gives him a chance to redeem himself in the eyes of Gotham. It's an interesting way to develop his character in the context of the fanfiction.
One common theme is Plastic Man's relationship with the other characters in the Btbatb universe. For example, his interactions with Batman can lead to some interesting stories, like how they work together despite their different personalities. Another theme could be Plastic Man's origin story, exploring how he got his powers and how it affects his role in the Btbatb world.
One great Plastic Man x Batman fanfiction is 'The Unlikely Alliance'. It shows how their different personalities, Plastic Man's elasticity and laid - back nature and Batman's brooding intensity, come together to solve a mystery in Gotham. It has some really interesting character interactions.
The theme of attraction in an unlikely pairing also exists. Despite being on opposite sides, there can be an underlying attraction between Batman and Cheetah in some fanfictions. This creates a lot of tension and drama as they struggle with their feelings while still being enemies. It's a very interesting dynamic that makes for engaging reading.
One common theme is the idea of the speed reader being a unique asset to Batman's crime - fighting. Maybe they can quickly analyze evidence or decrypt messages at a super - fast speed. Another theme could be the relationship dynamic, like the speed reader being in awe of Batman's skills and Batman being intrigued by the speed reader's special ability.
Another theme is redemption. Some fanfictions explore the idea that the villains in Batman's 'harem' could be redeemed through their relationship with him. It's like Batman's influence starts to change them, and they might start to use their skills for good instead of evil. It's a really interesting take on the characters.
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.
In this type of fanfiction, the exploration of the human psyche beneath the masks is a big theme. Batman and the villains all wear masks, literally and metaphorically. In a yaoi context, they start to strip away those masks for each other. There's also the theme of sacrifice. Batman might be willing to sacrifice his principles a bit for the villain he has feelings for, and vice versa. This adds a lot of depth and drama to the stories. And of course, the theme of attraction between two very different personalities, which is what makes yaoi - inspired fictions so interesting in general.
One common theme is the struggle with their superhero duties while dealing with the pregnancy. Another could be the relationship changes between them.

Redemption is another one. Sometimes the OC tries to redeem Bane from his villainous ways. This can lead to some really emotional and character - driven storylines. For example, in some fics, the OC might see the good in Bane that others don't. It's all about exploring the grey areas of his character. And this can be really engaging as it gives a new perspective on Bane.
