Perhaps Crowley as a child was an experiment in Hell. The higher - ups were trying to create a new type of demon with more intelligence and adaptability. Crowley was the result, and he had to grow up quickly, learning to navigate the dangerous politics of Hell while also dealing with the fact that he was different from other demons.
In some fanfictions, Crowley was a child who was abandoned in Hell. He had no one to guide him, so he had to figure things out on his own. This led to him making some bad choices early on, but also made him extremely resourceful. He learned how to make deals and manipulate situations to his advantage, which became his trademark when he became a powerful demon.
One possible backstory could be that Crowley was born into a lower - class demon family in Hell. He had to fight for every bit of power and recognition. As a child, he saw the unfairness in the demon society and decided he would one day rise above it all.
In fanfiction, Crowley as a child might be a precocious little devil. He could already show signs of his future cunning and ambition. Maybe he was constantly getting into minor mischief in Hell, trying to outwit the other young demons and gain an edge even at a young age.
Well, I really like the fanfic 'Crowley's Secret Alliances'. It shows Crowley forming unexpected partnerships in the Supernatural world. There's also 'A Day in the Life of Crowley' which gives a really in - depth look at his daily activities. And don't forget 'Crowley vs. the Archangels', it has some great action scenes involving Crowley.
One popular Crowley Supernatural fanfiction is 'Crowley's Redemption'. It delves into the idea of Crowley trying to break free from his demonic nature and seek some form of salvation. Another one could be 'Crowley and the Winchesters' which focuses on his complex relationships with the main characters. There's also 'Crowley's Hidden Powers' that explores some untapped abilities Crowley might have.
One common theme is the struggle between good and evil. Since Crowley is a demon, his relationship with his soulmate often challenges his demonic nature. His soulmate might be good - hearted, and Crowley has to decide whether to embrace the good or stay true to his evil ways.
One common theme is the exploration of relationships. Since Crowley is a woman, her interactions with male characters like Dean and Sam can take on a different dynamic. There could be more of a romantic or a strong female - male friendship aspect. Another theme is power. How does her gender change the way she wields power as a demon? Does she face different challenges or opportunities?
A simple plot could be that Crowley's daughter is raised by humans. She has no idea about her father until strange things start to happen around her. She then embarks on a journey to find out about her true parentage and along the way discovers the world of Supernatural. And when she finally meets Crowley, she has to decide if she wants to accept him or not.
Maybe there was a curse or a spell placed on him that made him forget his true identity. This could have been done by an enemy of his family or kingdom. As a result, he grows up believing he is just a normal boy with no special heritage.
One possible fanfiction idea could be that Crowley's daughter is half - human and she struggles with her demonic heritage. She might try to find a way to be different from her father and his cruel ways in the Supernatural world.
A great fanfiction idea is that Crowley's daughter is actually a key to opening a portal to another dimension. The Supernatural characters have to protect her from various creatures who want to use her for this purpose. She has to learn how to use her own abilities to defend herself and those she cares about.
The mystery around Crowley's character in Supernatural makes any story about his sister interesting. We know Crowley is a complex and devious demon, so imagining what his sister might be like adds a whole new layer of intrigue.
