History YMMV / KillLaKill

** Inumuta's final Goku Uniform has been compared to that of a CharClone. In the dub, he is voiced by Creator/SteveStaley, who later went on to play another CharClone, [[Anime/MobileSuitGundamIronBloodedOrphans McGillis Fareed]].

* MagnificentBastard: [[BigGood Sōichirō Kiryuin]] is the brilliant father of [[Characters/KillLaKillRyukoMatoi Ryuko]] and husband of Ragyo, whose schemes to upend the latter's evil fall into place throughout the series. Originally an ally to Ragyo, Sōichirō betrayed his wife when she callously experimented on their daughters, Sōichirō convincing young [[Characters/KillLaKillSatsukiKiryuin Satsuki]] to rebel against her mother at an older age while he personally spirited infant Ryuko away to safety. Faking his death and expertly disguising himself as "[[TwoAliasesOneCharacter Isshin Matoi]]", Sōichirō developed the Rending Scissors and the Kamui Senketsu, tricking Nui Harime into overlooking their potential when she assassinated him and leaving both for Ryuko to find and utilize. Long after his death, Sōichirō's intentions for Ryuko, Senketsu and the Scissors come to pass, as [[Characters/KillLaKillNudistBeach Nudist Beach]]--founded by Sōichirō himself--leads an insurrection against Ragyo alongside Ryuko and Satsuki, taking down Ragyo and the Life Fibers exactly as Sōichirō intended.

** [[SugaryMalice Nui Harime]] is the [[FauxAffablyEvil seemingly]]-[FaceOfAnAngelMindOfADemon sweet]] Grand Couturier of REVOCS and Ragyo Kiryuin's most powerful agent. A [[GigglingVillain giggling]] psychopath who is eager to see the culmination of Life Fibers [[KillAllHumans annihilating all human life on Earth]], Nui kicked off Ryuko's quest for revenge when Nui viciously murdered the girl's father, Isshin Matoi. Continuing to bulk up REVOCS' power and the creation of COVERS with her own two hands, Nui later causes all sorts of mischief by turning Ryuko into a rampaging monster before playing a key role in her horrible MindRape and brainwashing. After a failed attempt to force Ryuko and her allies to massacre each other, Nui merges her essence with the Original Life Fiber and [[FusionDance combines with Ragyo]] as a last-ditch effort to ensure the annihilation of humanity.

** [[EvilMatriarch Ragyo Kiryuin]] is the [[CorruptCorporateExecutive CEO]] of [[Characters/KillLaKillKiryuinConglomerate REVOCS]] and the [[AbusiveParents monstrous mother]] of [[Characters/KillLaKillSatsukiKiryuin Satsuki Kiryuin]] and [[Characters/KillLaKillRyukoMatoi Ryuko Matoi]]. Aiming to annihilate all human life on Earth with the alien Life Fibers, Ragyo previously married the genius scientist Soichiro/Isshin, having her daughters with him and using them for experiments with the Life Fibers, callously throwing away Ryuko when she thought her work had killed her daughter. Over the years, Ragyo has Soichiro hunted down and murdered when he betrayed her, and frequently [[ParentalIncest subjects Satsuki to sexual abuse]]. Reunited with Ryuko seventeen years later, Ragyo immediately breaks her mind into subservience and later molests her mind-controlled daughter before sending her off in an attempt to kill her friends resisting Ragyo. While preparing for her apocalyptic endgame, Ragyo has nearly all of humanity converted into enslaved, mindless COVERS to build herself an army and while Satsuki is held in her captivity, continues to subject the helpless young woman to further sexual assault. Even when eventually defeated by Ryuko and offered a chance for reconciliation, Ragyo refuses any kinship and [[SpitefulSuicide spitefully kills herself]], cementing her status as a hollow megalomaniac whose only desire was to dominate everything under her own will.
** [[Characters/KillLaKillNuiHarime Nui Harime]] is the Grand Couturier of REVOCS and Ragyo Kiryuin's most powerful agent. A [[GigglingVillain giggling]] psychopath who is eager to see the culmination of Life Fibers [[KillAllHumans annihilating all human life on Earth]], Nui kicked off Ryuko's quest for revenge when Nui viciously murdered the girl's father, Isshin Matoi. Continuing to bulk up REVOCS' power and the creation of COVERS with her own two hands, Nui later causes all sorts of mischief by turning Ryuko into a rampaging monster before playing a key role in her horrible MindRape and brainwashing. After a failed attempt to force Ryuko and her allies to massacre each other, Nui merges her essence with the Original Life Fiber and [[FusionDance combines with Ragyo]] as a last-ditch effort to ensure the annihilation of humanity.

* DracoInLeatherPants: There are some fans who believe that Satsuki's actions in the beginning of the series were completely justified. Her later revealed FreudianExcuse and GoodAllAlong nature are often used as examples for this belief.
** Nui Harime gets this treatment by some fans, mainly because of her cute appearence and quirky personality, which often tends to be exaggerated in {{Fanon}}, [[MisaimedFandom completely missing the entire point of her character]].

** Comparing Ryuko to VideoGame/ShadowTheHedgehog was a running joke in the ''Kill la Kill'' fandom since the beginning. Come episode 24, and [[spoiler:her EleventhHourSuperpower final form]] is basically Super Shadow, colors and all. Hell, [[spoiler:the final battle even takes place in space, just like in ''VideoGame/SonicAdventure2''! There's even a HeroicSacrifice in the end.]] This got an ApprovalOfGod during the [[Blog/SonicTheHedgehogTwitter Sonic Twitter Takeover]] in 2019 where Shadow states that his favorite anime is indeed ''Kill la Kill''. Then come 2021, ''WebAnimation/DeathBattle'' pits Ryuko against Shadow himself.
*** The ''VideoGame/SonicAdventure2'' parallels extend to the soundtrack as well as Ryuko's {{Leitmotif}} "Before my Body is Dry" contains the lyrics "Don't lose your way," and [=SA2's=] theme song "Live and Learn" contains the lyrics "You may never find your way."

** Ragyo's [[spoiler:[[ sexual abuse of Satsuki]] either gave the latter a legitimate FreudianExcuse for her actions and made her a more sympathetic character, or was a hasty and clumsy plot twist that came out of nowhere that was designed to shock the viewers into discounting all her previous actions. Additionally, many a debate has been had over whether it perfectly illustrated how heinous of a villain Ragyo actually is, or if it was a step too far. There is also a faction that feels that the writers [[spoiler:used ParentalIncest]], [[SeriousBusiness a very heavy and sensitive topic]], purely for shock value. And that they not only didn't portray it realistically, but also handled it with all the subtlety and tact of a sledgehammer.

* IAmNotShazam: You know that song that plays whenever Ryuko is about to do something awesome? It's called "Before My Body is Dry", ''not'' "Don't Lose Your Way".

* FetishRetardant:
** Even within the camp that normally enjoys fanservice, there is the contingent that finds the kamui's transformed appearances to be so [[WTHCostumingDepartment ridiculous-looking]] that the fanservice becomes unappealing and grotesque.
** Ragyo in general is this. Any fanservice moments involving her often have her sporting a creepy look on her face or have disturbing context, or made more disturbing by knowing what kind of person she, or a combination of the above, and it's made even worse be the scenes in question involve her own children. She makes any fanservice into instant {{Squick}}.

* EvilIsSexy: Pretty much every single female antagonist has some form of sex appeal, while also subverting an element of this somehow:
** Satsuki and Nonon [[spoiler:were GoodAllAlong. Nonon actually {{invert|edTrope}}s this, as she [[SensibleHeroesSkimpyVillains wears more revealing clothing]] when fighting against the bad guys]].
** Ragyo's [[spoiler:creepy treatment of her own daughters, full stop]].
** Nui is the [[spoiler:most childlike character in the series not named Mankanshoku in both look and demeanor]].
** [[spoiler:Brainwashed Evil Ryuko wears a relatively modest and [[FashionVictimVillain ridiculous outfit]] compared to her normal self]] yet has amassed quite a fanbase.
