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.
Well, in Suicide Squad fanfiction about Joker and Harley, their relationship is a study in contrasts. Joker is this unpredictable, cruel character. He has a hold over Harley that she can't seem to break. Harley, on the other hand, is this vibrant, if a bit crazy herself, woman who is desperately in love with him. The fanfiction often explores how their relationship develops, whether Harley will ever break free from Joker's influence, or if she'll keep being his loyal sidekick and lover in this dark and dangerous world they inhabit.
One popular theme is Harley's redemption. Writers often explore how she can break free from the Joker's influence and find her own identity. Another theme is the origin of their relationship, like how Harley became so obsessed with the Joker in the first place.
In Suicide Squad fanfiction, the relationship between the Joker and Harley Quinn is often complex and intense. The Joker is typically portrayed as a controlling and manipulative figure, while Harley is blindly in love with him despite his abuse. Their relationship is a twisted form of love that blurs the lines between sanity and madness.
One key element is the clash of different universes. Bella Swan comes from the relatively normal (compared to the Suicide Squad's world) world of Twilight. So, when she's thrown into the Suicide Squad's world led by the Joker, there's a big contrast in values, powers, and the general way of life. Another element is the relationship between Bella and the Joker. It could be a relationship of enmity, where the Joker sees Bella as a new plaything or an ally in some strange plan he has. Or it could be a more complex relationship where Bella tries to understand the Joker's madness and maybe even reform him. Also, the action and adventure elements are important. The Suicide Squad is known for its dangerous missions, and Bella getting involved in those adds a lot of excitement to the fanfiction.
Another one to check out is 'Among the Clowns'. It creates a unique backstory for an original character in the Suicide Squad Joker -centric universe. The story has some really creative interpretations of the Joker's relationship with other characters, both from the original Suicide Squad and the new OC. It's a great read for any fan of the character.
In the fanfiction, Harley's character development can be quite diverse. Sometimes she starts as a meek psychologist who is slowly corrupted by Joker. As the story progresses, she becomes more assertive in her own way, even if still under Joker's spell. She might learn to stand up to him a bit more while still being in love with him.
