In Harley Quinn x Blood fanfic, a major element is the clash of different aesthetics. Harley Quinn is known for her fun - loving, if a bit deranged, appearance with her jester - like costume and makeup, while Blood has a more horror - inspired, dark aesthetic. This contrast can create really interesting visual and narrative moments. Also, the power dynamics play a role. Whether Harley gains new powers in the Blood world or has to face off against powerful Blood - related entities, it adds to the story's tension and excitement.
Well, we could expect to see the authenticity of real - life situations. Maybe it'll show how Sebastian Quinn interacted with the people around him, his family, friends, or colleagues.

If it's a good adaptation, it should give us a deep understanding of his character and the events that shaped his life.
