In many 'harry x castiel angel of death fanfiction', the theme of identity also comes up. Both characters have very distinct identities. Harry is known as a wizard, a hero in his own right. Castiel is an angel with a specific role. When they come together, they often question and redefine their identities. They might start to see themselves in a new light because of their relationship with each other. This exploration of self - identity in the context of their relationship is quite common.
One popular 'harry x castiel angel of death fanfiction' might be 'The Unlikely Bond'. It explores an interesting relationship between Harry and Castiel where they team up against a common enemy in a world filled with magic and the supernatural elements that come with Castiel being an angel of death. Another could be 'Crossed Realms' which delves into how their two very different worlds, Harry's magical one and Castiel's more religious - supernatural one, collide and they learn from each other.
One common theme is the exploration of mortality. Since the Angel of Death is involved, it often makes the characters confront the idea of death more directly. Another theme could be the blurring of the lines between good and evil, as the Angel of Death might not fit neatly into either category.
Another theme is the struggle between their different natures. Castiel being an angel and Dean being a human hunter. This creates a lot of internal and external conflict in the stories, like in 'The Clash of Worlds' fanfiction where they have to overcome their differences to be together.
One common theme is redemption. Castiel's angel wings can be seen as a symbol of his past as an angel and his journey towards redemption in the stories. His wings might be damaged or lost and then regained as he becomes a better version of himself.
Well, a frequent theme is the exploration of different power structures. In Harry Potter, there's the hierarchy in the wizarding world, and in Castiel's world, there are hierarchies among angels. Fanfiction might look at how these different power systems compare and contrast. Also, friendship across different universes is a common theme. Characters from Harry Potter and Castiel's world forming bonds despite their differences.

One common theme is the exploration of the 'otherness' of Castiel as a creature. How his non - human nature makes his relationship with Dean more complex. For example, in many fics, his inhuman strength or abilities might be a source of both help and trouble in their adventures together.
