''Manga/ZettaiKarenChildren'' is quite full of {{Shout Out}}s; not at Anime/GhostSweeperMikami levels, but Shiina is getting really good with this trope. Often enough, the reference is lampshaded pretty heavily too.

* Kaoru wants to purchase a toy in one episode that resembles [[LightNovel/HaruhiSuzumiya Haruhi]] almost exactly. Considering who Kaoru is voiced by, this doubles as an ActorAllusion.
** Much later, we have this [[http://fabien.li/tvtropes/zkc/ZKC_ch203_p11.png scene]]. Also doubles as an ActorAllusion.

* There's even a ShoutOut to ''Manga/DetroitMetalCity'' when Kaoru shows up in a [[http://www.mangafox.com/manga/zettai_karen_children/v17/c191/15.html Krauser mask]].
* The best shout out is chapter 126/episode 46, where a [[RewritingReality notebook that can change the future]] launches the cast into a ''Manga/DeathNote'' homage, starring Sakaki as L.
** Further on, Manga/DeathNote appears again in the form of the Children copying Light's [[http://www.mangafox.com/manga/zettai_karen_children/v14/c127/15.html various methods for hiding the note pages]]. Results in a GambitPileup.
** Kaoru uses Light's method for [[http://www.mangafox.com/manga/zettai_karen_children/v17/c162/1.html hiding her diary]].
* There's a ''Manga/SayonaraZetsubouSensei'' spoof at Minamoto's [[http://www.mangafox.com/manga/zettai_karen_children/v17/c158/8.html marriage interview]] and a ''Manga/JoJosBizarreAdventure'' one in the manga version.
** In the manga, the spoof is in a [[http://www.mangafox.com/manga/zettai_karen_children/v16/c145/10.html dream sequence]].
* In the manga, Fujiko wears [[Anime/CodeGeass C.C.'s]] 'suit' at one point. Also an ActorAllusion.
* A {{yonkoma}} gag strip has Kyosuke [[http://www.mangafox.com/manga/zettai_karen_children/v17/c171/2.html cosplaying]] as [[Manga/{{Bleach}} Gin Ichimaru]]. ''Also'' an ActorAllusion.
** Another one has a [[LightNovel/HaruhiSuzumiya Haruhi]] [[http://www.mangafox.com/manga/zettai_karen_children/v14/c124/1.html reference]] where he asks espers to join him.
* A small subtle one in the Anime, Kaoru's Pyschic Shield (probably most clearly seen in episode 7) is identical in shape, colour, and style to an [[Anime/NeonGenesisEvangelion AT Field]].
* The picture [[http://fabien.li/tvtropes/zkc/ZKC_ch105_p03.png here]] is similar to a scene from Project A-ko.
* In the anime, [[{{Animorphism}} Animorph]] Hatsune can morph into a Bowdlerized version of [[Manga/{{Devilman}} Sirene]].
* Sakaki is a [[Manga/BlackJack doctor who detests the Japanese medical hierarchy ''and'' wields scalpels as weapons]].
** Cosplayed [[http://www.mangafox.com/manga/zettai_karen_children/v07/c062.5/2.html here]].
* Surprisingly nobody else seems to have caught Manga/TheWorldGodOnlyKnows ref in [[http://fabien.li/tvtropes/zkc/ZKC_ch144_p11.png this page]]
* Kaoru [[http://www.mangafox.com/manga/zettai_karen_children/v07/c062/19.html gets a hat]] [[Manga/OnePiece and accompanying outfit]].
* And [[http://www.mangafox.com/manga/zettai_karen_children/v13/c115/3.html here]] the girls freak out a la Kazuo Umezu.
* Literature/{{Carrie}}, a purely psychic alter-ego/bodiless twin of Minamoto's ex.
* Fujiko uses [[Manga/JoJosBizarreAdventure Dio's]] 'piece of bread' analogy for all the lovers she's had.
* ToLoveRu: when [[http://fabien.li/tvtropes/zkc/ZKC_ch190_p03.png Lala's here]], you know fanservice is not far!
* In the manga, the [[Film/BladeRunner Voight-Kampff test]] is used to identify espers and gauge their PowerLevels.
** Incidentally, the [[spoiler:[[http://mangafox.me/manga/zettai_karen_children/v01/c001/46.html blaster]] issued to Minamoto bears a [[http://www.imfdb.org/wiki/Blade_Runner#LAPD_2019_blaster striking resemblance]] to Deckard's gun.]]
* Kaoru's sister [[http://www.mangafox.com/manga/zettai_karen_children/v17/c156/1.html cosplays]] [[Music/{{Vocaloid}} Hatsune Miku]].
* In another omake, Ninja Hanzo [[Manga/{{Naruto}} has a]] [[http://www.mangafox.com/manga/zettai_karen_children/v17/c234/16.html Sharingan]].
* When Minamoto [[ItMakesSenseInContext grows younger by 10 years]], the girls force him to [[WholesomeCrossdresser cross-dress]] and he ends up [[Manga/HayateTheCombatButler looking a little]] [[http://www.mangareader.net/zettai-karen-children/133/4]].
* Chapter 272 shows PANDRA's senior members in a dogfight with [[Literature/HarryPotter a boy flying on a broomstick with glasses and lightning shaped scars on his face who uses a wand to cast a "Spell of Death" in the skies above London]].
* Possibly unintentional, but it seems that Dane Cook's wish for a guy who can shoot lasers out of his crotch has finally come true.
* Episode 5 of ''The Unlimited'' has Franchise/LupinIII in a police uniform, WebVideo/TheNostalgiaCritic, and WebVideo/TheAngryVideoGameNerd [[http://ogiuemaniax.wordpress.com/2013/02/04/the-nostalgia-critic-in-zettai-karen-children-the-unlimited/ as random spectators.]] This [[https://www.facebook.com/permalink.php?story_fbid=492908027412181&id=127127037353766 didn't escape the notice]] of Creator/DougWalker, [[https://twitter.com/JesuOtaku/status/298582155024560128 or]] the [[http://www.youtube.com/watch?v=uNUfk3R157U notice of]] fellow ''Website/ThatGuyWithTheGlasses'' contributor WebVideo/JesuOtaku.
* Kaoru channels [[Manga/RoseOfVersailles Oscar]] [[http://manga.animea.net/zettai-karen-children-chapter-167-page-9.html during an]] ImagineSpot (with Minamoto becoming a very weepy Andre).
* [[Manga/HayateTheCombatButler Hayate and Nagi]] can be seen and heard very briefly in episode 9 as the girls and Minamoto are leaving the shopping center. He is also seen walking in a crowd with Tama, Nagi's pet tiger, in episode 18, shortly after Chisato ditches Kaoru spying on Aoi's date.
** Kaoru sees him briefly again in episode 26 with Nagi, who's trying to get a kiss from him.
** Nagi and several of the other girls are visiting the same park that the girl's class trip is on in episode 33. Hayate isn't there at that particular time, but he shows up at the very end to encourage Minamoto after everyone leaves him during what looks like an interrogation.
* In episode 10, Aoi teleports survivors from a sunken ship into their super-submarine while [[FistOfTheNorthStar ATATATATATATATATATATATATATATATATATATATAT]]ing.
* In episode 19, [[http://imgur.com/O58g4ax one of the biker club members looks like the leader of the Clown biker gang from]] {{Akira}
