Paranoid Villains are very common villains who are fueled by a deep fear of being harmed or weakened by others/someone and therefore, it is hard for them to trust others. This type of evildoer is very common in mythology, they willing to commit terrible atrocities to try and prevent what they see as an impending doom (they almost always fail).

Basically, a villain who lives in fear of being defeated by a particular hero, prophecy or, in some cases, even another villain and utilizes extreme methods to try and prevent their own doom (ironically often causing said doom) can be added to this category.

Many paranoid villains also suffer from paranoid personality disorder, which oftenly related to antisocial personality disorder. Therefore, this category can be an alternative for villains who aren't psychopaths, but show similar symptoms.
