Another theme is romance. Some fanfictions pair Ketch with other characters, either from the show or original characters created by the author. This could be a slow - burn relationship or a more immediate attraction - based one.
One common theme is redemption. Ketch has done some not - so - great things in the show, and in fanfiction, he often gets a chance to redeem himself. For example, he might help the Winchesters in a big way to make up for his past actions.
One plot idea could be Ketch getting involved in a time - travel adventure within the Supernatural universe. He could go back in time and interact with the Winchester brothers at different points in their lives, changing the course of events in unexpected ways.
You can try websites like Archive of Our Own (AO3). It has a vast collection of fanfictions including those related to Supernatural. Just search for 'Supernatural' in the search bar and then look for stories that might mention 'ketch' in the summary or tags.
Another option is to join Supernatural fan groups on social media platforms like Facebook or Reddit. Fans often share their favorite fanfictions in these groups. You can ask specifically for Ketch fanfictions, and someone might be able to point you in the right direction.
One common theme is power struggle. Abaddon is a powerful demon, so many fanfictions explore her battles for power, either against other demons or the Winchesters. Another theme is her backstory. Writers often delve into her past to give more depth to her character.
One common theme is forbidden love. Maybe a vampire falling in love with a werewolf in the academy, which goes against the norms of their species. Another is the underdog rising to power. A student who is initially underestimated but then discovers some great power within themselves.
One common theme is redemption. Since Adam had a rather rough deal in the show, a lot of fanfictions explore his journey towards redemption. Another is family. How he fits into the Winchester family dynamic, whether it's forming a bond with Sam and Dean or finding his place in the larger family of hunters.
One common theme is redemption. Cassiel has made some mistakes in the show, and in fanfictions, writers often explore his journey to redeem himself. For example, he might try to make up for his actions by helping Sam and Dean in a more selfless way.
One common theme is the aftermath of the events in the episode. Writers often explore how the characters deal with the consequences. Another theme could be the relationships between the characters, like Dean and Sam's bond, which might be further developed or tested in the fanfictions.
Character pairings are also a big theme. Some fanfictions might pair characters like Elsa with Dean, exploring how their different personalities and powers interact. There could be a story where Elsa's ice powers are seen as a form of magic that the 'Supernatural' characters have to either understand or combat. It often involves a lot of relationship building and character development within this unique crossover setting.
