'''Basic Trope''': A character who is evil is also bald.
* '''Straight''': One of the villains is bald.
* '''Exaggerated''':
** ''All'' villains are bald no matter what their age or gender, and all of the heroes have hair.
** Everyone that begins going bald turns evil simultaneously.
** And when someone turns evil, their hair instantly fall out.
* '''Downplayed''':
** A villain is bald, but he wears a toupee most of the time.
** He's only bald on the top, the sides have hair.
** A villain is not bald, but he is always seen with very short hair, indicating that he shaves his head very often.
* '''Justified''':
** [[FreudianExcuse Being taunted for his baldness at a young age]] was one factor that made the villain turn to the dark side.
** The villain has mental powers that are more powerful if there's no hair obstructing it.
** [[MostWritersAreHuman The villain isn't a mammal.]]

** A bald character who is a MisunderstoodLonerWithAHeartOfGold.
** A bald character was seen as a villain, but it's later revealed that he was at the hero side all along.
** The bald villain have a HeelFaceTurn.
* '''Double Subverted''': One of the villains is bald in the prologue or first few episodes or chapters, but there's a long time skip in the storyline and it's implied that his head was shaved back then; most of the time we see him, he has hair. But then it turns out that's a wig.
* '''Parodied''': One of the villains decides to make an army of bald evil minions, as part of his plot to blind enemies from the sunlight reflected on their heads.
* '''Zig Zagged''': An evil character appears to have hair, but the narrative is constantly switching sides on whether or not it's a wig or if he's bald.
* '''Averted''': The villains all have at least some hair on their heads.
* '''Enforced''':
** A lot of the characters look similar, and the creators figure that viewers won't be able to tell the villain apart easily unless he has a bald head that glimmers in the light whenever he appears.
** The writer thinks Evil is Ugly, and that baldness is ugly.
** The actor is bald, and any attempt to give him hair looked ridiculous.
* '''Lampshaded''':
** "Fear me and my shiny bald head of doom, mortals!"
** "You know, a little Rogaine would make this world a much nicer place to live in."
* '''Invoked''': A character [[FaceHeelTurn goes to the dark side]] and [[GoodHairEvilHair shaves his head]] because he thinks it better fits his new alliance.
* '''Exploited''':
** The big bad decides to go bald in order to look more menacing.
** The villain uses this trope against the bald hero. Since people equate hairlessness with evil, [[HeroWithBadPublicity the public opinion will turn against the good guy]] if a smear-campaign starts drawing attention that detail.
* '''Defied''':
** "No! I cannot let myself go bald or people will figure out how evil I am on first sight!"
** "Just because I'm going bald doesn't mean I have to become evil."
* '''Discussed''': "Wait, so that's three bald evil guys we've run into so far. Do you think that baldness and evil may be related?"
* '''Conversed''': "Do you suppose the Dark Warlord needs sunscreen for his denuded scalp?"
* '''Deconstructed''': There is some kind of chemical or radiation in the environment that causes madness and insanity, but also makes the victim's hair fall out. Our villain is simply an innocent victim of this suffering, slowly being destroyed by the negative effects of the substance.
* '''Reconstructed''': A scientific process used to boost intelligence and knowledge has the side effect of causing baldness. It's later revealed that it removes empathy altogether, making them evil scientists. If the process is reverted, hair grows back.
Shine in the sun back to BaldOfEvil.
