A common theme is survival. In the endverse, everything is in chaos and characters have to fight to stay alive. Another theme is the loss of hope. The world is so desolate that it's easy for the characters to feel hopeless.
One great supernatural endverse fanfiction is 'The End of All Things'. It really delves into the dark and gritty world of the endverse. The characterizations are spot - on, especially of Dean and his struggle in that desolate future.
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.
If we're talking about Castiel from 'Supernatural', his story is complex. He is an angel who rebels against Heaven's orders. He becomes involved with the Winchester brothers, Sam and Dean, and helps them fight various supernatural threats. He has his own journey of self - discovery, dealing with his loyalty to Heaven, his newfound friendships with humans, and the struggle between good and evil in the context of the show's universe.
Harry Potter himself would be very interesting. Castiel could be intrigued by Harry's connection to Voldemort and his role as the 'Chosen One'. He might offer Harry some unique insights from his angelic knowledge about dealing with dark forces, which could be different from what Dumbledore has taught him.
In dean - castiel relationship in such fanfiction, there's often a deep emotional connection. They might show a side of extreme vulnerability towards each other. Their relationship can be intense, with a lot of passion and a sense of 'destined to be together' kind of feeling.

I'm not sure specifically what 'castiel broken fanfic' is about without reading it. It could be a fan - created story that focuses on a character named Castiel and perhaps some sort of broken or damaged state, like his broken spirit, broken relationships, or a broken situation he's in within the fanfic's universe.
Definitely. The 'Castiel is an archangel' fanfics are popular among Supernatural fans. They usually offer unique interpretations of the story. For example, they might show how Castiel's new status as an archangel affects his friendship with Dean and Sam. They can also introduce new plotlines and conflicts based on his enhanced abilities.
There's also 'Wings and Hunters'. This one is unique as it focuses on a different aspect of their relationship, almost like a what - if scenario. It imagines a world where their connection is tested in ways that are both exciting and heart - wrenching. The story has a great flow and the descriptions are vivid.
