The fanfiction also gives fans a chance to be creative in a very specific niche. There are so many ways to combine the lore of Supernatural with the concept of Castiel and cats. It could be a story where Castiel is a cat shifter, or a cat is his guide in the supernatural world. These unique ideas and the freedom to explore them make it appealing.
You can try fanfiction websites like Archive of Our Own (AO3). It has a vast collection of fanfics, and you can simply search for 'Supernatural Castiel Cat' in the search bar. There are likely to be many creative stories there.
One great aspect of Castiel and Dean in fanfiction is their dynamic. Their relationship, which is complex in the show, can be explored even further in fanfictions. Writers often delve into their unspoken bond, creating scenarios where they support each other in ways not shown in the original series. For example, some fanfictions might have them going on a road trip together just for the sake of exploring new places and having deep conversations about their pasts and futures.
Fanfiction about Castiel in Supernatural can be really interesting. Some 'hopeless' fanfictions might focus on his often tragic or difficult situations in the show. They could explore his loyalty to Dean and Sam even when things seem truly hopeless for him. Maybe it's about his struggle with his angelic nature and the chaos of the human world he's thrown into.
Castiel's relationship with his powers might also change. He may have to limit his use of angelic powers to protect the unborn entity. This can cause internal conflict as he is used to using his powers freely. At the same time, it can also show his growth as a character, as he is willing to sacrifice some of his power for the sake of something new and precious.
There's also a story where Castiel kidnaps a fan in a desperate attempt to save the world. It's a complex plot that involves time travel and alternate universes. You can find it on FanFiction.net. The story really delves into Castiel's character and his motives behind the kidnapping.
I remember reading a fanfic called 'Castiel's Wounds'. In this story, Castiel is severely injured during a battle with demons. The fic focuses on how Sam and Dean try to help him recover, and the relationship dynamics between the three are really well - written. It shows Castiel's vulnerability in a very believable way. There's also 'A World of Hurt' which explores Castiel's hurt in a post - apocalyptic setting, adding an extra layer of tension and drama.
Well, 'The Road Less Traveled' is a popular 'Supernatural Dean and Castiel fanfiction'. It's set in a post - apocalyptic world where they have to rely on each other more than ever. It has great character development and some really intense scenes. There's also 'Soulmates in the Shadows' which plays with the idea of them being soulmates in a unique way.
One common theme is redemption. Since Castiel has made some mistakes in the show, a lot of fanfiction focuses on him trying to make up for those. Another theme is his relationship with the other main characters, like Dean and Sam. His loyalty and how it is tested is often explored.
I really like the fanfic 'Castiel's Endless Burden'. It shows Castiel constantly feeling the pressure of being different from other angels due to his relationship with the Winchesters. It's a story full of angst and self - discovery for Castiel, and the way it's written makes you feel his pain.
