History Main / OneBadMother

Has nothing to do with AbusiveParents. ''Usually''.

* M.U.T.H.E.R., the crazy ''{{Earthbound}}''-style master-computer in the bunker from ''WesternAnimation/TheVentureBrothers''

* Mothergod was the villain in a [[Crisis Crossover]] from Valiant comics.

* In the ''Series/DoctorWho'' episode [[Recap/DoctorWhoNSS3E2TheShakespeareCode The Shakespeare Code]], there were three evil alien "witches" called Carrionites, of which the older two were both called "Mother" by the third.

* Ma Lilywhite in [[Discworld/{{Hogfather}}]]. Her son Medium Dave is a hardened criminal thug, and her anger is his worst nightmare.

* MotherBank from ''Sci Spy''
.* The BigBad of the second ''ComicBook/YoungAvengers'' series is a shapeshifting, extra-dimensional parasite named Mother. She generally takes the form of Teddy's dead mom, and acts like a sweet, doting parent who just wants to eat their child's soul and take over their dimension. Worse, she can brainwash other parents and adults into following her every command.

* Mother Brain in ''{{Metroid}}''.
* Mother Brain in ''VideoGame/ChronoTrigger''. Not quite certain why it [[NamesTheSame shares a name]] with the ''{{Metroid}}'' example.

* Mother Machine/Machine Mother (Editors? What editors?) from Kamandi at Earth's End.
* The BigBad of the second ''ComicBook/YoungAvengers'' series is a shapeshifting, extra-dimensional parasite named Mother. She generally takes the form of Teddy's dead mom, and acts like a sweet, doting parent who just wants to eat their child's soul and take over their dimension. Worse, she can brainwash other parents and adults into following her every command.

* Ma Dalton from ''LuckyLuke''

* ''Franchise/MassEffect'''s Matriarch Benezia qualifies, not just because of her title but also because she was the literal mother of one of the main characters (although to be fair it was more a case of [[spoiler:mind control than intentional villainy, though it took a long time to make that clear]].
** The Rachni queen you meet on Noveria also calls herself the "mother." [[spoiler: However, [[SubvertedTrope she's not evil]].]]

* Mother in ''{{La Mulana}}''. Justified as she actually is a creator goddess.

* The ''AnitaBlake'' series has an ubervampire called "Marmee Noir". Anita dubs her "MommieDearest".

* The Un-Mother on ''{{Inuyasha}},'' though only in the dub. In Japanese, she's the mythological creature ''mu onna'', which translates into "nothing woman."

* The Un-Mother on ''{{Inuyasha}}.''

[[folder:{{Film}}]]
* The ship computer in ''Film/{{Alien}}'' was MU-THR 182 or something like that. And it wasn't the villain, nah, it was just programmed by the Weyland-Yutani Company (who we all know are evil). If anything, Ash turned out to be a sort of villain.
** ''Film/AlienResurrection'', was set much later and "Mother" has been replaced with a new OS, "Father". This trope is played with when someone takes over the computer and a female voice announces to the evil scientist "Father's dead, asshole."

* Animal Mother from ''FullMetalJacket'' is (presumably) an example of the CurseCutShort version.
* Mother Gothel from ''{{Tangled}}''.
* Averted in ''{{Sneakers}}''--Dan Aykroyd's character was named "Mother", but was a good guy.

* [[Series/{{Supernatural}} The Mother of All]]

* ''MassEffect'''s Matriarch Benezia qualifies, not just because of her title but also because she was the literal mother of one of the main characters (although to be fair it was more a case of [[spoiler:mind control than intentional villainy, though it took a long time to make that clear]].

* In ''[[StrangeJourney Shin Megami Tensei: Strange Journey]]'', you have the four mothers Maia Ouroboros, Tiamat, Maya, and [[FinalBoss Mem Aleph]]. Especially notable in that Tiamat is stated to have given birth to all of the demons in the game, and Mem Aleph is the mother of all life on Earth.

* The eponymous Fluttermama, of Tumblr blog "[[http://ask-fluttermama.tumblr.com/ Ask Fluttermama]]", is the {{Pattycakes}} version of Fluttershy. Infantilism fetish and Mind Rape are involved.

* One episode of ''Series/DoctorWho'' had three evil alien witches called Carrionites, of which the older two were both called "Mother" by the third.

* Maurice "Mom" Boucher of the Hell's Angels. Yes, he's a man, but making fun of gangsters for their name is [[CaptainObvious usually not a good idea]].
