Villains who are considerably less dark and evil than what is considered normal for the work in which they appear, having a comedic presence within a story that is otherwise serious; this is the exact opposite of, and mutually exclusive from, Game Changer. These villains are usually seen in TV shows, as they sometimes become more nasty, depending on the episode.

Please do not confuse this with the standard Comedy Villain. It is almost impossible for a Big Bad to be a Comic Relief, because if the main antagonist is comical, then by default most of the story's other elements will be comical as well and this trope cannot apply to the work. The only exception would be if a story primarily driven by realistic drama inexplicably had a comical or cartoonish bad guy who was the only recurrent antagonist but who was irrelevant to the rest of the plot.

Comic reliefs can have their more threatening moments (such as when their true intentions are revealed, i.e. GLaDOS) but their comedy must be more prominent and/or remembered.

Purely Evil villains can never qualify because their acts are always serious and fearsome. This is applicable even if they appear to be funny.

Examples include Condiment King, Tabitha, and Shlubb and Klump.
