One popular type is where the OC has a unique power and they team up with Castiel on a quest. For example, an OC who can see the future might help Castiel prevent a major disaster. Another popular theme is a romantic relationship between the OC and Castiel, exploring how they navigate the differences between an angel and a human - like in a story where the OC is a hunter and they fall in love while on a hunt together. There are also stories where the OC is from another dimension and Castiel has to figure out how to send them back while also developing feelings for them.
Well, a lot of Castiel x OC fanfictions revolve around the idea of redemption. Maybe the OC has made some bad choices in the past and Castiel sees the good in them and tries to help them redeem themselves. And then there are the ones that are set in alternate universes. For instance, an AU where angels and humans live together in harmony and the OC and Castiel meet in a more peaceful setting, like at a school for supernatural beings, and their relationship blossoms from there.
Some good Castiel x OC fanfictions focus on character development. The OC could start off as a timid character but grow stronger with Castiel's guidance. In these stories, the relationship between them evolves as the OC overcomes their fears. There are also those that play with the concept of time travel. The OC might be from a different era and Castiel has to adjust to their old - fashioned ways while protecting them from the dangers of the modern world they've landed in.
One popular Castiel OC fanfiction might be those that explore a new relationship dynamic for Castiel. For example, a story where the OC is a powerful witch who teams up with Castiel to fight a common enemy. This type of story can introduce new plot twists and character developments.
The popularity also comes from the fact that fans love to imagine different versions of their favorite characters. A fem Castiel brings a whole new set of possibilities in terms of character development and relationship building with Dean. It allows for stories that might not be possible with the original male Castiel. For example, in some fanfictions, fem Castiel might show more vulnerability or a different kind of strength, which makes for really interesting reading when paired with Dean's character.

One great fem Castiel x Dean fanfiction is 'Heavenly Bonds'. It beautifully explores their relationship in a new, more intimate way. The author does an amazing job of portraying fem Castiel's unique personality traits and how they interact with Dean.
I really like 'Castiel's Guiding Light'. In this fanfiction, the reader is lost in the dark and chaotic world of the Supernatural series. Castiel appears as a guiding light in their life. The story is filled with heart - warming moments as Castiel helps the reader understand the supernatural world and in the process, they fall for each other.

One great one is 'His Dean' which really delves into Castiel's possessive nature towards Dean. It shows how Castiel's angelic intensity combines with his newfound feelings of possession in a really interesting way. The author does a wonderful job of portraying their relationship in a unique and engaging manner.
The 'Forbidden Love' trope is quite common. Given Castiel's angelic nature and the rules in the Supernatural world, a relationship between him and a human reader might be seen as forbidden. This adds an element of tension and drama to the story. Also, the 'Healing' trope, where the reader helps Castiel heal from his past traumas or vice versa, is often used. They support each other through difficult times, which makes for a heart - warming story.
One popular trope is the 'unlikely alliance'. Diaval, being Maleficent's servant raven, might form an unexpected bond with the OC. For example, they could team up to protect the Moors from an outside threat. Another trope is 'forbidden love'. Given Diaval's loyalty to Maleficent, a relationship with an OC could be seen as going against his duties, adding a layer of drama. And the 'discovery of powers' trope is also common. The OC might discover a hidden power within themselves with Diaval's help or influence, leading to a journey of self - discovery.
