There are also fanfictions that explore a more complex relationship between them, beyond just the typical hero - villain dynamic. For example, they might be forced to work together against a greater threat, and in the process, they develop a grudging respect for each other that leads to an unexpected bond.
Redemption is another theme. Sometimes Bane is written as a character seeking redemption, and his relationship with Batman becomes a part of that journey. This can add a lot of depth to the story.
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.
Power dynamics are really common. Batman's moral code against Bane's more ruthless nature creates an interesting tension. Also, themes of secrecy and discovery are often there. Since they are from different sides of the law, keeping their relationship a secret and the discovery of it by other characters can be a major plot point. There can also be themes of mutual understanding over time as they get to know each other on a deeper level.
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.
Adventure is also a theme sometimes. The writers might create a new world or situation where Will and Mike go on an adventure together. During this adventure, their relationship can develop and change. It could be a magical quest where they have to rely on each other's strengths to succeed and in the process, their bond grows stronger.
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.
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.
One common theme is the struggle with their superhero duties while dealing with the pregnancy. Another could be the relationship changes between them.
