And then there's the theme of mystery. The world of Constantine is full of secrets, and fanfictions often dig deeper into these mysteries.
The theme of the battle between good and evil is also prevalent.

His unique approach to dealing with demons and the supernatural makes this theme play out in different and exciting ways compared to the native characters of the crossovers.
The theme of the unknown and mystery is also prevalent. Since Constantine brings in a whole new realm of the supernatural, there are often mysteries to solve that are beyond what Team Arrow is used to. This could be anything from a demon possession in Star City to an ancient curse that affects the city's inhabitants. The fics usually revolve around the characters trying to figure out these mysteries and stop the threats.
One common theme is the clash of different magic systems. The magic in the Harry Potter world is more structured and often associated with good, while Constantine's magic is darker and more chaotic.
