As expected from show made by former StudioGainax staff, ''Anime/KillLaKill'' is absolutely [[TropeOverdosed overflowing]] with [[ShoutOut shout outs]]. The list below is in fact only a portion of all the known shout outs and references in the show. A more complete list is currently being compiled by the fans [[https://dl.dropboxusercontent.com/u/225692543/References.html here]].

!!General
* ActorAllusion: Several cast members along with guest voice actors were part of ''Anime/TengenToppaGurrenLagann'' 's main cast, so this factor has been played around for a little bit within the script.
** One that's worth mentioning is the CatchPhrase [[note]]"Let me give you two pieces of information."[[/note]]of Tsumugu [[note]]Creator/KatsuyukiKonishi, played Kamina in TTGL. [[/note]], this line was originally Viral's [[note]]NobuyukiHiyama, who plays Sanageyama in story. [[/note]] line when he first encountered Kamina.
** When Nui rips up Sanageyama's uniform, she calls him a "naked ape." Not only is this JustForPun, but the fact that this was what Viral, who's a beastman, called human beings in general to disdain them. Now that his actor is playing a human being, this phrase was used back at him ironically.
** Creator/ToshihikoSeki as [[Series/KamenRiderDenO the demonic character reduced to being a physical upgrade to the lead character.]] With ButtMonkey moments thrown in!
* Most of the main characters including the Ryuko, Mako, Satsuki, Mikisugi and the student council can be considered to be expys of characters from ''Anime/CuteyHoney'' and ''Re: Cutey Honey''. [[http://imgur.com/tA5nXXp See here]].
** Ryuko = Cutey Honey - Father killed by mysterious party. Seeks revenge using secret technology created by her father to transform into a scantily-clad warrior of justice.
** Mikisugi = Seiji Hayami - Mysterious man with a connection to the protagonist and her father. Helps her discover her powers.
** Mako = Honey Kisaragi - Genki Airhead that only desires friendship and food. Tends to get into risqué situations.
*** Mako also strongly resembles manga Natsuko - Cute, bubbly DamselInDistress who immediately decides the new transfer student is her new best friend ([[SchoolgirlLesbians and crush]]).
** Mataro = Junpei - Perverted younger brother that has a crush on the protagonist and acts as comic relief
** Satsuki = Natsuko Aki - No nonsense woman who doesn't have time to deal with the protagonist's issues. Not really sure if she's a friend of foe?
** The Elite Four = Gold, Cobalt, Scarlet and Black Claw - 4 bosses leading up to the final boss.
** Ragyo = Sister Jill - the imposing female BigBad.
* At the beginning of the series the main characters also have some similarity to the three female leads of ''Anime/ProjectAKo'': a brash, impulsive, tomboyish girl (Ryuko / A-ko) is friends with a ditzy, hyperactive, childish classmate (Mako / C-ko) and is antagonized by a stern, snobbish and ultra-rich lady (Satsuki / B-ko) who is not afraid to don a skimpy super-suit if this means better chances of success.
* Mako's design is similar to that of [[http://imgur.com/7oy2ve0 Pinoko]] from ''Manga/BlackJack'', complete with her famous "Ohmigewdness!" pose in episode 3.
* The last scene of the beginning credits features a gloved hand evidently grasping air, with details that suggest it may be a shoutout to [[Anime/NeonGenesisEvangelion Asuka's famous "I'll kill you" scene.]] Which, given the staff and the context of the story, might not be too far off.
* The first ending is almost scene-to-scene identical to the ending of the 1985 live action version of the manga ''{{Manga/Sukeban Deka}}'', as seen [[http://i.imgur.com/CMirYj8.jpg here]].
* The second ending pays homage to the [[http://i.imgur.com/qu1H0Ck.png?1 first opening]] of ''Manga/UruseiYatsura''.
** Two of Mako's costumes during said ending are [[Anime/PantyAndStockingWithGarterbelt a scantily-clad angel]] and WebAnimation/InfernoCop.
* The ending credits list Guts, the Mankanshokus' dog, as voiced by "'''?'''" [[note]]His voice actor had revealed himself, see Trivia Page.[[/note]] - Gainax already did this in ''{{Anime/FLCL}}'' where Miyu Miyu, Naota's cat, was credited as voiced by "'''?'''" (eventually revealed as Creator/HideakiAnno).
* The decision to translate ''Shitennō'' as "Elite Four" is likely a reference to ''Franchise/{{Pokemon}}''. [[spoiler:They even challenge Ryuko to a BossRush in episode 8, just like the Elite Four in the''Pokemon'' games]].
* Honnoji Academy has a tall tower overlooking the school grounds similar to [[Anime/RevolutionaryGirlUtena Ohtori Academy]].
* Honnoji City has a spiral highway going around it, Mako has a spiral watch, guess what [[Anime/TengenToppaGurrenLagann other anime]] made by the creators also used spirals?
* Each one of the Elite Four's Goku Uniforms has a Shout Out to the most well known works the staff of Studio Gainax produced.
** Blade Regalia: ''Anime/{{FLCL}}'' - The giant robot/desperado/hand with a weapon on each finger.
** Shackle/Scourge Regalia: ''Anime/PantyAndStockingWithGarterbelt'' - Garterbelt and Corset's bondage theme.
** Probe Regalia: ''Anime/NeonGenesisEvangelion'' - Asuka's ''Anime/RebuildOfEvangelion'' [[{{Stripperiffic}} infamous Eva Test Plug Suit]] with a different color scheme.
** Symphony Regalia: ''Anime/TengenToppaGurrenLagann'' - Over the top mecha and Dai-Gurren's crest on Nonon's shoulder.
* The way the next episode previews cut to split-second frames of large white text on black is also used in ''Anime/NeonGenesisEvangelion''.
* Satsuki's Kamui, Junketsu, bears some [[http://img1.ak.crunchyroll.com/i/spire2/ef66b7b2f48d6aa0da1f604aa241544c1383180748_full.png striking]] [[http://www.slashattack.com/wp-content/uploads/2011/09/gunbuster4.png similarities]] to the eponymous SuperRobot, of Gainax's ''Anime/{{Gunbuster}}''.
** Also, the [[http://ani.me/site_media/media/articles/2013/10/26/Kill_la_Kill_Ep4_02_jpg_157x118_crop_upscale_q85.jpg Honnouji Academy insignia]] is the same as the [[http://i2.wp.com/deculture101.wordpress.com/files/2008/12/vlcsnap-5080654.jpg?fit=1000%2C1000 Space Force military insignia]] from ''Anime/{{Gunbuster}}'', albeit inverted.
* Senketsu, on the other hand, bears an uncanny resemblance to [[http://i.imgur.com/mPz7kcg.jpg Mazinger Z]].
* The X symbol on the soldier's "uniforms" of Nudist Beach is identical to the X symbol used by the ''Franchise/{{X-Men}}''. Particularly the ones from the the ''WesternAnimation/{{X-Men}}'' cartoon from the 90's. Though here the X represents their hatred of clothing; Their flag is a red X over a pair of underwear. Whereas in X-Men it was a symbol for Charles Xavier.
* Of course, the '''blatantly''' obvious one is the [[Anime/DragonBallZ Goku]] Uniforms themselves, which give the wearer superpowers [[spoiler: and are fueled by alien lifeforms]].

!!Episode 1: "If Only I Had Thorns Like a Thistle..."
* The episode's title is taken from Miyako Chaki's "''Azami no gotoku toge areba''" ([[https://www.youtube.com/watch?v=aPXD915n2IE YouTube]]).
* Satsuki's first lines (see DoubleSpeak on the main page) are taken almost verbatim from ''Literature/NineteenEightyFour''.
* Satsuki refers to the other students as pigs in human clothing, perhaps a reference to [[Literature/AnimalFarm a certain novel]] that also deals with themes of totalitarianism and inequality.
* One of the students in Mako's and Ryuko's class can be seen playing with a Hulk and Destroyer action figures, both characters from MarvelComics.
* Ryuko's first scene where she walks across a bridge into town, gets harassed by neighborhood gangs, and beats them up thereby earning respect, is straight out of ''Anime/AshitaNoJoe''.
* Ryuko carrying her Scissor Blade in a guitar case and her search for revenge for the death of a loved one is an apparent shout-out to Robert Rodriguez's ''Film/{{Desperado}}''.
* The scene where Ryuko lands onto the pile of cloths at the secret basement of her house bleeding, and then awakening Senketsu from below in search of the blood's owner, [[http://imgur.com/vNCddr0 is practically identical to how Teppei met]] [[OneLetterName X]] in Masami Kurumada's ''Anime/BtX''.
* Mako uses the Kinnikuman Kinniku Buster on Mataro.
* Mako and Ryuko getting crucified (or pinned/hung) upside down is similar to how Mayumi Takahasi gets tied up in ''Anime/KekkoKamen''.
* The [[http://imgur.com/kf055UD student's salute is a direct copy]] of the [[http://imgur.com/jFqthj5 salute from the German film]] ''Film/TheWave'', adding to the vibe of totalitarianism or even fascism Honnoji Academy gives off.

!!Episode 2: "So Sexy, I'm Going to Faint"
* The episode's title is taken from Char's "''Kizetsu suru hodo nayamashii''" ([[https://www.youtube.com/watch?v=8hktD1u2uA0 YouTube]]).
* Isshin's letter to Mikisugi refers to the kamui as "just like dead leaves in the forest". ''Anime/DeadLeaves'' happens to be another anime that Hiroyuki Imaishi directed.
* Episode 2's tennis scenario is similar to ''Manga/AimForTheAce''.
** Hakodate's speech about having only yourself to rely on on the court is parallels the opening narration of ''Aim for the Ace!'' as well.
* Hakodate's interchangeable visors swivel like a [[Anime/ArmoredTrooperVotoms Scopedog's]].

!!Episode 3: "Purity"
* The episode's title is taken from Saori Minami's "''Junketsu''" ([[https://www.youtube.com/watch?v=p_NbQCG7WVo YouTube]]).
* The choreography of Ryuko and Satsuki's fight in episode 3 where both are silhouetted in black on a white background is similar to Utena and Juri's fight in ''[[Anime/RevolutionaryGirlUtena Adolescence of Utena]]''.
* [[http://imgur.com/haRoOak During one of Mako's speeches, she forms herself into the]] [[Anime/SpaceRunawayIdeon Ideon gauge]].

!!Episode 4: "Dawn of a Miserable Morning"
* The episode's title is taken from Jun Mayuzumi's "''Totemo fukō na asa ga kita''" ([[https://www.youtube.com/watch?v=EBMQg4FEZhc YouTube]]).
* Ryuko's face after she was hit by pie, made her look like No-Face from ''Anime/SpiritedAway''.
* The scene where the school bus is being pelted by an endless barrage of bullets is reminiscent of the action style of Imaishi's first directorial work, ''Anime/DeadLeaves''.
** It could possibly be also a reference to the climax of Creator/ClintEastwood's 1977 film ''[[http://www.imdb.com/title/tt0076070/ The Gauntlet]]'', where he is using an armored bus [[http://imgur.com/Fok8991 to drive through]] the titular gauntlet of policemen.
* The scene in when the school bus hurtles through the air to the ''Blue Danube'' is a clear nod to ''[[Film/TwoThousandOneASpaceOdyssey 2001.]]''
* The One-Star mom that calls in the hijacking is given the order to eliminate [[Film/ApocalypseNow with extreme prejudice]].
* The animation for the explosions are very similar to the ones in ''Anime/PantyAndStockingWithGarterbelt''.
* The scene where Mako moans "kaikan~" ("ecstasy") while [[InterplayOfSexAndViolence manning the turret gun]] references the climatic machine gun scene from the 1981 movie version of ''Film/SailorFukuToKikanjuu''.
* While Ryuko, Mako and Maiko are running across the bridge over the lava pit, one of the bones floating in it is [[Film/Terminator2JudgmentDay a skeletal hand giving a thumbs up]].
* [[Film/ETTheExtraTerrestrial Mataro riding a bicycle with Guts, a pug wearing a hoodie, in the basket.]]
* When Mako's father is bringing Senketsu to Ryuko, he [[http://i.imgur.com/HSaD1HL.jpg drives past]] Vincent Vega and Jules Winnfield from ''Film/PulpFiction''.

!!Episode 5: "Trigger"
* The episode's title is taken from Masanori Sera & Twist's "''Hikigane''" ([[https://www.youtube.com/watch?v=5LC0zTa_OJo YouTube]]).
* Tsumugu's "let me tell you two pieces of information" catchphrase echoes Viral's first lines to Kamina in episode 3 of ''Anime/TengenToppaGurrenLagann''.

!!Episode 6: "Don't Toy with Me On a Whim"
* The episode's title is taken from the Southern All Stars' "''Kibun shidai de semenaide''" ([[http://www.youtube.com/watch?v=_j6XwEvTaY0 YouTube]]).
* Sanageyama [[spoiler:gaining more power by going blind]] is very much an homage to ''ComicBook/{{Daredevil}}'' and/or ''Franchise/{{Zatoichi}}''.
* Ryuko getting buried on the ground with only her legs sticking straight up is similar to how Unit-01 and Unit-02 get beaten up in one episode of ''[[Anime/NeonGenesisEvangelion Evangelion]]''.

!!Episode 7: "A Loser I Can't Hate"
* The episode's title is taken from Kenji Sawada's "''Nikumi kirenai rokudenashi''" ([[https://www.youtube.com/watch?v=pojy_AY2tHE YouTube]]).
* Ryuko shoves a bottle of ''[[Manga/LuckyStar Timotei Shampoo]]'' into Mataro's face when he catches him peeping on her.
* A pretty obvious one in episode 7 with Ryuko forming a Film/FightClub.
* The dishwasher Sukuyo's holding seems to be modelled after a [[Main/NintendoEntertainmentSystem Famicom.]]
* The Two-Star uniform [[spoiler:Club President Mako]] gets in episode 7 is a bancho outfit, complete with chewing [[OralFixationFixation straw]] and ripped up hat a la ''Otoko Ippiki Gaki Daisho'' and ''Dokaben.'' Commonly mistaken for a [[Manga/JoJosBizarreAdventure JoJo]] reference, it's a parody of series that did it [[OlderThanTheyThink at least 20 years earlier]] though virtually unknown outside Japan.
* Club president [[http://kill-la-kill.wikia.com/wiki/Jack_Nait%C5%8D Jack Naito]] is basically [[WesternAnimation/{{Superjail}} Jacknife]], and [[http://i.kinja-img.com/gawker-media/image/upload/t_ku-medium/18lrqxkp4mecvpng.png not just]] InNameOnly.

!!Episode 8: "I Will Wipe My Own Tears"
* The episode's title is taken from Katsuhiko Miki's "''Ore no namida wa ore ga fuku''" ([[https://www.youtube.com/watch?v=mwoxVT2hW1o YouTube]]).
* [[http://24.media.tumblr.com/adb3a56fd187955614ca4d47b75f8e24/tumblr_mwmo4hMEUG1qlsrn9o1_500.gif This]] scene seems to be a shout out to the ''Manga/CromartieHighSchool'' [[http://www.youtube.com/watch?v=_4R7j5iR7JM&feature=youtu.be&t=53s opening theme]], especially given KLK's director Imaishi also storyboarded the ''Cromartie'' opening.
* The [[http://31.media.tumblr.com/b5e6655f33d9cc980c9369ba7fef71fb/tumblr_mx45w8k3ak1rsrw1oo1_500.jpg Akio]] [[Anime/RevolutionaryGirlUtena Car]] makes an appearance. Not only is the car nearly identical, but the route they take is nearly identical to the one Akio drove around when making his speeches.
* Gamagoori's driving in episode 8 may be a Shout Out to the ''Anime/PantyAndStockingWithGarterbelt'' episode "Death Race 2010", where the car ghost wiped out the Daten City police cars by [[EverythingIsBetterWithSpinning spinning]]. How the Daten Police tried to subjugate the ghost by ramming into it is also replicated.

!!Episode 9: "A Once in a Lifetime Chance"
* The episode's title is taken from Hideki Saijo's "Chance ''wa ichido''" ([[https://www.youtube.com/watch?v=vgxFpApRhVM YouTube]]).
* The design of Gamagoori's Scourge Regalia bears a lot of similarities to ComicBook/IronMan and Comicbook/WarMachine, as well as ''Anime/DigimonFrontier'' 's [[http://digimon.wikia.com/wiki/Susanoomon Susanoomon]].
** And its cocoon form looks a lot like [[Anime/NeonGenesisEvangelion Zeruel]]. It even has a similar method of attack.
** Although it is partially obscured, Gamagoori's transformed Goku Uniform bears a passing resemblance to [[Anime/PantyAndStockingWithGarterbelt Corset's outfit]], especially in the pointed shoes.
* Given the high density of Marvel references in Goku Uniforms in later episodes, Senketsu Senjin's WolverineClaws are likely a reference to ''the'' ComicBook/{{Wolverine}}.
!!Episode 10: "I Want to Know More About You"
* The episode's title is taken from Hiroko Yakushimaru's "''Anata o motto shiritakute''" ([[https://www.youtube.com/watch?v=y5WWnd50hJ0 YouTube]]).

** When Ryuko had Senketsu enlarge his eye, it looked a lot like a smaller Sahaquiel.
** [[http://i.imgur.com/bFmcoaY.jpg Gamagoori holding a]] [[DoesThisRemindYouOfAnything white cloth]] with a framing very similar to the infamous ''End of Evangelion'' opening scene ([[spoiler:Shinji masturbating to and ejaculating on Asuka while she's unconscious]]).
* Inumuta's HUD looks very similar to the one in the IronMan movies.
* Inumuta's smile after his hacking scene looks just like Light Yagami's smile in {{DeathNote}}.
* Ryuko's outfit becoming skimpier in order to pull off a huge attack brings to mind VideoGame/{{Bayonetta}}.
* Take a close look at Nonon's transformed Goku uniform, specifically her left shoulder. On it is a [[Anime/TengenToppaGurrenLagann VERY familiar-looking skull]].
* Nonon's Symphony Regalia Grave and Senketsu Shippu look very similar to the [[Anime/MobileSuitGundam0083StardustMemory Dendrobium and Dra-c]]

!!Episode 11: "I'm Not Your Cute Woman"
* The episode's title is taken from Yuko Kanai's "''Kawaii onna to yobanaide''" ([[https://www.youtube.com/watch?v=IlIHy2QwrKc YouTube]]).
* The horns on Jakuzure's hat in Symphony Regalia: Da Capo call to mind {{Galactus}}.
** The way she fires from her hat using the same regalia is similar to how the [[Anime/MobileSuitGundamZZ Double Zeta Gundam]] fires its [[WaveMotionGun High Mega Cannon]].

!!Episode 12: "Spit Your Sadness Away"
* The episode's title is taken from Naoki Hongo's "''Kanashimi ni tsuba o kakero''" ([[https://www.youtube.com/watch?v=EQ4ft1rdGcQ YouTube]]).
* Nui mentions that [[spoiler:fixing Ryuko's monster form]] is [[Manga/JoJosBizarreAdventure useless, useless, useless, useless.]]
* [[spoiler:The whole sequence with [[BodyHorror Ryuko's mutated, monster form]] shares semblance to both [[Anime/NeonGenesisEvangelion Unit 01's Berserk state]] and [[Film/TheThing1982 The Thing]].]]
** [[spoiler:But it most resembles William Birkin of ''VideoGame/ResidentEvil2'' fame, especially his second stage.]]
** [[spoiler:The transformation itself with Senketsu swallowing Ryuko with a huge toothy mouth resembles the way Naota is taken inside Canti in ''{{Anime/FLCL}}'']]
** [[spoiler:Berserk Ryuko bears strong resemblance to the ComicBook/IncredibleHulk in that she would never hurt [[MoralityChain Mako]] and the fact that Mako is the only one who can calm Ryuko down enough to reverse her transformation]]
** The seven scars on Ragyo Kiryuin's back are a reference to [[Manga/FistOfTheNorthStar Kenshiro's]] seven scars.

!!Episode 13: "Crazy for You"
* The episode's title comes from Toshihiko Tahara's "''Kimi ni barabara...to iu kanji''" ([[https://www.youtube.com/watch?v=C0InS4fCOPI YouTube]]).
* The whole passage in REVOCS HQ is one big reference to ''Anime/NeonGenesisEvangelion'':
** The city where REVOCS HQ is situated has the company logo, a blood red logo with the name of the company in capitalized letters, [[SigilSpam on the facade of every tower]], like NERV's leaf was on all of Tokyo-3's buildings.
** Then the camera shows the "cone-shaped" base of REVOCS building at an angle that make it looks like a pyramid, reminiscent of NERV's HQ pyramid.
** Ragyo's speech mentions mankind's original sin and the Fruit of Knowledge, two themes often presents in Gendo's dialogs.
** Ragyo's personnal office is basically a circular version of Gendo's famous office, with the complete lack of furniture except a lone desk, strange marking on the ground and ceiling and windows circling the entire office providing the only source of light.
** REVOCS itself, a sinister multinational god-building think tank answerable to apparently no one, is actually a mere front for COVERS...an even more sinister multinational god-building think tank answerable to apparently no one, exactly like NERV was a front for [[AncientConspiracy SEELE]].
* Mako's brother and dad running in circles until they turn into butter is a reference to ''Little Black Sambo''.
* [[spoiler:Nui's ability to create and operate human-like puppets with strings of Life Fiber]] reminds of Leonof the Puppetmaster from ''{{Manga/Trigun}}'', who similarly created extremely lifelike puppets and moved them with strings.
* [[spoiler:Senketsu's apparent DeathByAThousandCuts]] may remind some of the ending of ''PantyAndStockingWithGarterbelt''.

!!Episode 14: "Ride Like the Wind"
* The episode's title comes from Takao Hirata & Cellsters' "''Isoge Kaze no you ni''" ([[https://www.youtube.com/watch?v=xYj9BNKST4s YouTube]]).
* The big tusked turtle guardian brings to mind a certain other [[{{Franchise/Gamera}} guardian turtle]].
* A villainous force invades Osaka militarily. The citizens of Osaka harness their community power and keep the bad guys at the gate. That is one of the battles in ''Anime/BurstAngel''.
* Inumuta appeared as a very ''Franchise/StarWars''-like blue hologram.
* Did Mako channel [[Manga/FistOfTheNorthStar Kenshiro]] to catch all that money being shot at her?

!!Episode 15: "Don't Stop Me Now"
* The episode's title comes from Linda Yamamoto's "''Dō ni mo Tomaranai''" ([[https://www.youtube.com/watch?v=JNg5U2DAx3U YouTube]]).
* In the Aniplex sub Takarada says that [[Film/TopGun he's not going to write a check his body can't cash.]]
* The new version of Shackle Regalia continues the ComicBook/IronMan trend, [[https://24.media.tumblr.com/dc2879edafc5f432b8303df4962ec2ab/tumblr_mzvkrveLUE1rbnx7io1_500.png this time resembling]] [[http://static2.wikia.nocookie.net/__cb20100402062443/marveldatabase/images/4/41/Hulkbuster_%28Modular_Addon%29.png the Hulkbuster Armor.]]
* The new version of Blade Regalia looks somewhat similar to Elemental Hero Neos from ''Anime/YuGiOhGX'', which was in turn based on Ultraman designs.
* Ryuko squirting blood into Satsuki's eyes is reminiscent of what [[Manga/JoJosBizarreAdventure DIO]] did in his battle against Jotaro.
* Jakuzure's new uniform bears a strong resemblance to the PoweredArmor from the ''LightNovel/InfiniteStratos'' series. Her hat also brings to mind Galactus' helmet, with its upward pointing, angled side-horns.
* [[Anime/TengenToppaGurrenLagann Boota]] can be seen in a [[http://i.imgur.com/J8jWsN8.png freeze-frame]] when Takarada's Dotonbori Robo bursts from the ground.

!!Episode 16: "The Girl Can't Help It"
* The episode's title comes from Reiko Ōshida's "''Onna wa sore o gaman dekinai''" ([[https://www.youtube.com/watch?v=wwNagNtLyA4 YouTube]]), and from the film ''Film/TheGirlCantHelpIt'' (which shares its Japanese title with the name of the song).
* During one of the early scenes with the Dotonbori River in the background, there's a statue of [[{{UsefulNotes/KFC}} Colonel Sanders]] neck-deep in the river, referring to the infamous [[{{Curse}} Curse of the Colonel]].
* [[spoiler:When Mikisugi explains that Life Fibers are aliens, Mako wonders whether he means [[{{Film/Alien}} xenomorphs]]. In addition, she also visually alludes to a famous [[http://img.photobucket.com/albums/v650/DavidTedesco/alien31.jpg alien hoax picture]].]]
* As Mikisugi is making his lecture, at one point he is seen posing in various historical outfits - including some made famous by 1980s [[Music/MichaelJackson Michael Jackson]], Aladdin Sane-era Music/DavidBowie, {{Music/Madonna}}, and [[Music/SexPistols Sid Vicious]].

!!Episode 17: "Why Are You...?"

* When Nudist Beach and Ryuko go to stop the Culture Festival, Mako says [[Film/ThePrincessBride "Have fun storming the stadium!"]]
* Ragyo quotes ''Theatre/{{Macbeth}}'' to summarise Nui's mentality: "Fair is foul and foul is fair".

* The arrival of [[spoiler:COVERS]] in Honnouji is visually very similar to the Impact vortexes from ''Anime/RebuildOfEvangelion''.
* Three of the Nudist Beach members in one scene strongly resemble [[WesternAnimation/TheLegendOfKorra Korra, Mako, and Bolin]].
* Sanageyama's uniform's death scene is very reminiscent of [[ActorAllusion Viral's]] [[Anime/TengenToppaGurrenLagann Enkidudu]]'s death scene, down to the remark where the weapons reach their limit.

!!Episode 20: "Far from the Madding Crowd"
* The episode's title comes from Tomoko Ohta's "''Tōku gunshū wo hanarete''". The English episode title refers to the Thomas Hardy novel of the same name.
* The motorcycle shop Ryuko got her badass bike from is called [[WebAnimation/InfernoCop Inferno]].
* Sanageyama's "The enemy awaits at Honnouji!" is a reference to the famous line Akechi Mitsuhide supposedly said when he betrayed Oda Nobunaga.
* The Nudist Beach flagship strongly resembles the Dai Gurren from ''Anime/TengenToppaGurrenLagann''
** And what's it called? [[Film/TheNakedGun Naked Sun]] (alternately may be a reference to [[http://en.wikipedia.org/wiki/The_Naked_Sun the novel of the same name]] by Creator/IsaacAsimov).
* This may not be a fully intentional one and more of a coincidence, but [[spoiler:Satsuki's escape and fighting COVERS with her feet]] brings to mind the naked Raiden gameplay segment of ''VideoGame/MetalGearSolid2SonsOfLiberty''.
* The scene where Gamagoori jumps from a helicopter and lands in front of Satsuki is based on a scene from ''{{Anime/FLCL}}'' where Naota and Lord Canti jump down and land in front of Mamimi.

%% "People die when they're killed" is not a Fate/stay night reference, but a play on a Japanese idiom that appears in several other works of fiction. %%

!!Episode 21: "Incomplete"
* The episode's title comes from Hiromi Gou's "''Mikansei''" ([[https://www.youtube.com/watch?v=QJvVtZ1lijw YouTube]]).
* At the end, when [[spoiler:Ryuko rips her way out of Junketsu]], after a brief trip inside her mind, we are treated to some shots that look suspiciously similar to Episode 16 of ''Anime/NeonGenesisEvangelion'', after Unit 01 bursts out of Leliel and stands soaked in a rain of blood.

!!Episode 22: "Tell Me How You Feel"
* The episode's title comes from Machiko Watanabe's "''Kuchibiru yo, atsuku kimi wo katare''" ([[https://www.youtube.com/watch?v=upLb9n4x0N0 YouTube]])
* Upon Senketsu reuniting with Ryuko, the way Ryuko puts on Senketsu looked like a TransformationSequence out of the SuperRobotGenre.
* In yet another American comic costuming reference, [[spoiler:Iori]]'s Goku Uniform features robot tentacles, evoking the appearance of ComicBook/DoctorOctopus, combined with the colors and AllEncompassingMantle of ComicBook/{{Spawn}}.
* Ragyo's plan involves [[spoiler:turning all of humanity into a HiveMind through use of a powerful extraterrestrial organism.]] [[Anime/NeonGenesisEvangelion Sound familiar]]?
* The [[spoiler:giant sized COVERS that attacks the Naked Sun]] is made to look like it has shades both on its "head" and its chest, just like a certain mecha from a [[Anime/TengenToppaGurrenLagann show by the same creators]].
* The dark shot of Senketsu's [[TronLines stripes]] [[PowerGlows glowing red]] with blood is likely a reference to ''Series/KamenRiderFaiz''. The titular Rider's suit had glowing red strips of Photon Blood powering it, becoming dramatically visible in the dark.
* Gamagoori carries Human Extraction Devices in the same weapons arrangement and hunched over pose of a [[Anime/{{Macross}} Destroid Monster]].

!!Episode 23: "Imitation Gold"
* The episode's title comes from Momoe Yamaguchi's "Imitation Gold".
* There seem to be several nods to ''Anime/TengenToppaGurrenLagann'' in this one:
** Sanagayama's transformation into his Final Goku Uniform is basically TTGL's transformation in reverse, his earlier, larger armor breaking away to reveal his later, smaller armor.
** The Elite Four's AsskickingPose after their transformation is shot almost identically to a scene from the third opening (GL and two Grapearls in a BackToBackBadasses pose surrounded by enemies).
** The Naked Dagger's attack on the Primordial Life Fiber is pretty much the same as the Dai-Gurren's attack on Teppelin, though in this case, it goes all the way through.
** And after that, when Ragyo is going ThisCannotBe, we get Ryuko, Satsuki, Mako and the Elite Four assembled in the same AsskickingPose from the final episode (with [[LesYay Ryuko carrying Mako in much the same way Simon was carrying Nia]]) complete with Ryuko giving a BadassBoast not too different from Team Dai-Gurren's motto.
* Sanagayama's Final Goku Uniform makes him look quite a bit like [[VideoGame/MetalGearRisingRevengeance Jetstream Sam.]]
* Inumuta's Final Goku Uniform has him sporting the same distinctive red, rhomboid, bridgeless sunglasses worn by TurnAGundam CharClone, Harry Ord mixed with the looks of a [[Franchise/KamenRider Kamen Rider]]. The suit's powers and overall emphasis on lithe acrobatics also makes it a reference to SpiderMan.
* During Inumuta's transformation he emerges from a computer bearing a striking resemblance to a SGI Challenge XL, including a Silicon Graphics logo with Inumuta Graphics written next to it. During the development of ''Anime/NeonGenesisEvangelion'' SGI workstations such as the Challenge XL were used for CG scenes.
* Gamagoori's Final Goku Uniform resembles a combination of Colossus and Apocalypse from the XMen.
* The bold text "In Heaven's Name, We Smite Clothing!" is a parody of divine wrath-themed InTheNameOfTheMoon speeches used in various [[Main/JidaiGeki jidai geki]] and anime like ''[[TheBraveExpressMightGaine Might Gaine]]''. [[DontExplainTheJoke Clothing rhymes with evil]] in Japanese.
* Mako's power levels while wearing her Two Star Fight Club Uniform are - baring intelligence - well [[Anime/DragonBallZ over 9000]].
* Ragyo proclaims that "[[Franchise/StarTrek Resistance is futile!]]" when fighting Satsuki.
* Nui's HUGE head looming over the characters [[http://knowyourmeme.com/photos/720597-kill-la-kill#comments is a nod to]] Lilith's rise in ''Anime/TheEndOfEvangelion''.

!!Episode 24: "Past the Infinite Darkness"
* The episode's title comes from Ichirō Araki's "''Hateshinaki yami no kanata ni''" ([[https://www.youtube.com/watch?v=5BBqY0_UrA8 YouTube]]), also the ending theme of the second ''AshitaNoJoe'' TV series.
* There's a few blatant ''[[Anime/TengenToppaGurrenLagann Gurren Lagann]]'' and references, to make the final episode even more epic:
** [[spoiler:Senketsu transforms on its own, without Ryuko, and drills a hole through Ragyo.]] The scene looks like Lordgenome's defeat by chest-drilling.
** [[spoiler:Gamagoori's ultimate Regalia]] turns him into what can be described as a "human Gunmen", looking much like the Gurren Lagann. He attacks using multiple projections of his own chest-face.
** [[ArsonMurderAndJaywalking Finally]], [[spoiler:during the end credits sequence Mako's backpack resembles the head of those "grape-hippo" creatures that appeared in the early episodes of the series.]]
* Some similarities to ''Anime/NeonGenesisEvangelion'' have been noted as well.
** Much like Sahaquiel impaling EVA-01's hands in [[Anime/RebuildOfEvangelion the remake]], Ragyo gets the palms of her hands impaled by [[spoiler:Satsuki's Gako and Koryu blades, only to break them instead.]]
** The Prime Life Fiber, [[spoiler:which was thought to have been killed, tangs itself and flows up to the school before reforming]].
** Gamagoori's [[spoiler:attack on the transmitter's shield]] has a shot of his hands ripping it open that is identical to the shot of EVA-01's hands ripping open Sachiel's A.T. Field.
** Nui's [[spoiler:assimilation into the Primordial Life Fiber]] was similar to [[spoiler:Rei's assimilation into Lilith whilst implementing Instrumentality, complete this time with a giant Nui-head growing out from the fibres.]]
** The Sword-Scissors, [[spoiler:in their final form, look uncannily similar to the Lance of Longinus.]]
** The freeze-frame from when, in Ryuko' and Ragyo's fight, [[spoiler:the first time Ragyo grows spikes and impales Ryuko]] is strikingly similar to [[spoiler:the one of Asuka's death]] in ''End of Evangelion''.
** Ragyo [[spoiler:growing glowing wings and shooting out rays of light which cause everybody to cower in fear]] is strongly reminiscent of [[spoiler:Arael's Trauma Beam.]]
** An overly passive half-alien woman named Rei [[spoiler:getting absorbed into a white giant in order to complete a generations-old plan to turn humanity into orange stuff.]]
* Tsumugu and Aikuro's combined DTR looks a lot like Chouryuujin from ''Anime/{{GaoGaiGar}}''.
* Inumuta's Regalia referencing ComicBooks/SpiderMan becomes even more obvious in this episode, with him doing Spidey's gestures and substituting computer cables for webbing.
* At one point various world cities are shown. In the New York sequence, a billboard advertising the ''[[Disney/TheLionKing Lion King]]'' musical and the insignia of the [[Film/{{Prometheus}} Weyland Corporation]] appear.
* Ryuko [[spoiler:impales herself on Ragyo's arm in a direct reference to ''Anime/{{GunBuster}}'']]; the act, poses, and perspective are all identical. [[spoiler: Compare [[http://www.youtube.com/watch?v=dOqvaer9PJg this]] (around 2:00) to [[http://www.youtube.com/watch?v=l4ySBWtH2ac this]] (around 2:40).]]
* [[spoiler:Senketsu Kisaragi]] is very clearly a homage to the ever-classic ''Anime/DragonBallZ'', from the basic physical details up to and including "I grow stronger when I'm on the verge of death!"
** The shot of [[spoiler:Ryuko facing a naked Ragyo in space, with Earth orbit as background]] is visually reminiscent of the final part of Goku and Beers' fight in ''Anime/DragonBallZBattleOfGods'' (can be seen [[https://www.youtube.com/watch?v=6TkfOsf0wro here]] at about 12:00).
* [[spoiler:The death of Senketsu]] [[BookEnds book ended]] in the exact same fashion as the original manga ending of ''Anime/BtX''[[note]]Episode 1 used Bt'X as reference, hence the book ends.[[/note]], where [[spoiler:X dies by using all of his protection system on Teppei and his brother Kotaro, sending them back to Earth as he disintegrates.]]
* The final battle has also been noted to be strikingly similar to the climax of ''VideoGame/SonicAdventure2'', complete with [[spoiler:a Super Form involving the use of multiple elements, the battle taking place in space around an orbiting satellite, and one of the heroes sacrificing themselves and dying while falling back to earth. It would make sense considering the comparisons people made with Ryuko and Shadow.]]
** Also, [[spoiler:some people may be reminded of the ending to ''Series/KamenRiderOOO'', where it also had the sidekick dying while the hero falls into their cast of allies]].
* At one point, Ragyo gets a horned "headdress" that makes her look just like a white version of [[Disney/SleepingBeauty Maleficent]].
* Shinra-Koketsu looks similar to [[{{VideoGame/Persona4}} Izanami]]. May also be an ActorAllusion as Creator/RomiPark voiced that character.
* Ragyo's [[spoiler:[[BetterToDieThanBeKilled defiant suicide]] by pulling her own heart out, holding it up then crushing it]] sure resembles a villainesque take on Musashi's iconic {{heroic sacrifice}} in ''Manga/GetterRobo''.
* During Mako's spotlight speech, when talking about how Ryuko can create a perfect world, she turns into the "It's A Small World After All" ride from the Ride/DisneyThemeParks.
* When Ragyo gets [[spoiler:cut into four separate pieces by Ryuko and Satsuki]] the situation looks very similar to how [[spoiler:Dio Brando of ''Manga/JojosBizarreAdventure'' got bisected during his fight with Jonathan. It is also similarly ineffective and doesn't impair Ragyo's ability to talk]]

!!Episode 25: "Goodbye Again"
* The episode's title comes from Kiyohiko Ozaki's 1971 song, "''Sayonara (wo) mou ichido''" ([[https://www.youtube.com/watch?v=aUe6ln1CNFA YouTube]]).
* The controls for the Final Defense Apparatus are identical to a [[Anime/TengenToppaGurrenLagann Gunmen]].
* [[WesternAnimation/TheLegendOfKorra Mako, Bolin, Korra, and Pabu]] [[http://38.media.tumblr.com/7af7476eda13ad8d056adbf55680ee97/tumblr_n1pqi0k42f1qjsrbmo1_400.jpg appear]] as members of Nudist Beach.

!!Drama CD 1: "I Really, Truly Appreciate Your Work"
* The first drama CD's title comes from The Drifters' 1970 song, "''Honto ni Honto ni Gokurōsan''" ([[https://www.youtube.com/watch?v=fm929ajpWjI YouTube]]).

!!Drama CD 2: "Between the Night and the Morning"
* The second drama CD's title comes from Shinnosuke "Peter" Ikehata's 1969 debut single, "''Yoru to Asa no Aida ni''" ([[https://www.youtube.com/watch?v=9Dwl9xwEJvI YouTube]]).
