Another theme is the exploration of madness. The Joker represents insanity, and when paired with an OC, it allows the writer to explore how a 'normal' person might be affected by or interact with such extreme madness. It could be about the OC slowly losing their sanity or finding a way to understand the Joker's brand of madness.
One common theme is the power struggle. The Joker is a powerful and chaotic character, and the OC often has to find a way to either match his power or outwit him. For example, in many stories, the OC might have a unique ability that gives them an edge in this struggle.
Well, a frequent theme is the struggle for power. The Joker is a power - hungry character. In these fanfictions, the OC might be trying to gain power within the criminal underworld that the Joker and Harley operate in. Also, the theme of redemption can sometimes be there. Maybe the OC tries to redeem Harley from her life with the Joker. There are also themes of loyalty and betrayal as the characters' relationships shift and change.
One common theme is the corruption of innocence. The male oc often starts out with some sense of normalcy or goodness, and the Joker gradually chips away at that. Another theme is the exploration of chaos and order. The Joker represents chaos, and the male oc may be trying to bring some order or may be completely swept up in the chaos. Power dynamics is also a theme, with the Joker usually being in a position of power over the male oc, at least initially.
The theme of unpredictability is quite common too. The Joker is famously unpredictable, and when you add a criminal OC into the mix, it amps up the element of surprise. Readers never really know what they are going to do next. Whether it's a sudden change in alliance or a new scheme they come up with, this keeps the readers on the edge of their seats. It also allows for a lot of creativity in the writing as the authors can take the story in unexpected directions.
One common theme is the exploration of madness. Since the Joker is known for his insanity, OC characters often get caught up in his world of chaos and have to deal with their own sanity being tested.
One common theme could be the power dynamic between the Joker and the OC. Since the Joker is such a complex and powerful character, exploring how an OC interacts with him in terms of power can be interesting.
One common theme is chaos. The Joker is all about chaos, and when you introduce an original character (oc), it often shows how the oc either thrives in or tries to combat that chaos. For example, in many fics, the oc might be trying to bring some order to the Joker's madness.
Another theme is the battle between good and evil, especially within the OC themselves. They might start out with good intentions but be slowly corrupted by the Joker's influence. This internal struggle is often explored in great detail in these fanfictions, showing how the Joker's presence can be a catalyst for change, even if it's a change towards the darker side of human nature.
One common theme could be the struggle of the OC (original character) with the unexpected pregnancy in the chaotic world associated with the Joker. Another might be how the relationship with the Joker (if there is one) changes due to the pregnancy.
One common theme is the clash of two different worlds. Bella often represents a more innocent or 'normal' world while the Joker is all about chaos and anarchy. Another theme is the idea of transformation. Bella might be changed by her encounter with the Joker, or vice versa.
In some fanfictions, there's a theme of forbidden love. Given their roles within the group and the potential risks of a relationship getting in the way of their mission as Phantom Thieves, this adds an element of drama. Another common theme is the exploration of their different personalities. Makoto is more by - the - book and Joker is more of a wildcard, and how these differences complement each other in a relationship is often explored. There are also fanfictions that focus on their shared experiences in the Metaverse and how that bonds them on a deeper level.
