Witches

Witches are "usually" evil women that use their mastery of magic in order to get what they want, which could be the whole world and ruling it, or destroying certain kinds of people they want to be rid of, or just simply causing small problems. As villains, they often portrayed as female equivalent to Sorcerers (even Wizards and Warlocks), and in some settings, a witch is a different race to humans while other settings have them as humans that used dark magic. They are virtually commen villains due to several famous movies like "The Wizard of Oz", to the point that it's a commen archutype and a known Halloween Monster.
