The Adversary

''Like the Villain but smaller. Not physically, of course.''

The non-adventurous Villain whose intentions might not necessarily be evil, but are still negative and usually harm others in some way. They likely have some distaste for or rivalry with at least one of the members of the Main Cast (if not the entire Cast as a whole) and constantly tries to triumph over them, only to be thwarted at the end of the plot.

The Adversary shouldn't be confused with the Rival, who can be considered a "friendly Adversary" to the Main Cast. Where the Rival only competes against somebody from the Main Cast and doesn't mean to hurt them, the Adversary truly hates the Main Cast and tries everything in their power to get their way. It could be that somebody from the Main Cast Broke The Vase with the Adversary or that the Adversary is just a general villainous character who doesn't target anybody in particular unless it's for some kind of plan.
