First, know the character well. Study how Asmodeus was portrayed in Supernatural - his mannerisms, his goals, and his relationships. Then, come up with a unique plot. It could be something that was only hinted at in the show or a completely new scenario. For example, you could write about his time before he became a major character in the series.
Good characterization is key. Make Asmodeus consistent with his on - show personality, but also add your own twists. You can also add new characters that interact with him in interesting ways. When it comes to the writing style, use vivid descriptions, especially when it comes to the supernatural elements. If you're writing about his powers, describe them in a way that makes the reader feel like they're there. For example, if he's using his telekinesis, describe how objects move in a spooky and otherworldly manner.

When writing 'supernatural dehumanization fanfiction', start with a strong concept. Consider what it really means to be dehumanized in the context of the supernatural world.

And don't forget to keep the essence of the original character, so that readers can still recognize who they are despite the changes.

The mate has to decide whether to be loyal to Asmodeus, to their own kind, or to some other moral or ethical code.
