Villains.

Characters who opposed the protagonist.

There are charming villains, there are villains with a touching backstory, there are villains who are simply pure evil, there are villains you can sympathise, and there are villains who simply have that title because they aren't on the same side as the protagonist.

But no matter what kind of villain you are, at the end of the day, you are just a stepping stone for a protagonist.

But in this vast universe, where immortals can pluck the stars and gods can create the sun, there are villains who won't stand for their fate.

They will trample over the protagonist and defy their predestined fates and declare to the heavens,

“Villains aren't stepping stones!”
