It bears mentioning Derek Landy is a self-professed comic reader, gamer, movie geek, etc. Which is probably why there are so many of these.
* To ComicBook/{{Watchmen}} in the second book.
* Possibly to Franchise/TheHitchhikersGuideToTheGalaxy with the tagline of book three- 'Do Panic' on the cover.
* The CthulhuMythos are discussed several times.
* To TheBlairWitchProject in book four.
* [[ShoutOutToShakespeare To Hamlet]] on the Book Four cover.
* Part of a chapter towards the end of the fifth book seems to be lifted straight out of a certain swordfight scene from ''Film/ThePrincessBride''.
* There is a moment in the fifth book which references the "spanish inquisition" sketch from Monty Python.
* It was... [[Series/MontyPythonsFlyingCircus an ex- rabbit.]]
* One of the words used to [[spoiler: open the Crucible]] was "[[LordOfTheRings Mellon]]".
* Look out for the Empire Strikes Back reference in Book Five: "Not a scratch, Ghastly"
* There's a PosthumousCharacter named Trope in the third book. [[OneOfUs Coincidence? I think not.]]
* Valkyrie is worried about [[TheIncredibleHulk "hulking out"]] in book six.
* [[Franchise/{{Alien}} "Help, Sigourney Weaver! Help!"]]
* "Like [[Creator/SamuelLJackson Jules]], in ''Film/PulpFiction''?"
* "We're not [[Series/BuffyTheVampireSlayer Buffy]] and Series/{{Angel}}, OK? We're not RomeoAndJuliet. We're not those guys in ''Theatre/WestSideStory''. We're not even [[Literature/{{Twilight}} Edward and Bella]]."
** Speaking of which, there's no way the Valkyrie and Caelan subplot wasn't meant to be a mocking {{Deconstruction}} of Literature/{{Twilight}}
* In book 6, when Carol and Crystal ask Valkyrie to teach them some "tricks", she tells them they're not called tricks, and the twins correct themselves to saying [[Series/ArrestedDevelopment "illusions"]] instead.
* [[spoiler: Darquesse]] mentions flying like {{Superman}}.
** There's an earlier {{Superman}} reference in ''Playing With Fire'', where Valkyrie comments that Dusk ripping off his human skin is similar to how Clark Kent rips off his shirt.
* Tesseract might just be a ShoutOut to [[Franchise/{{Batman}} Bane.]]
* [[spoiler: Beryl]] is apparently a [[Franchise/StarTrek Trekkie.]]
* Darquesse's knowledge of swordplay consists of [[ASongOfIceAndFire "the pointy end goes in the other person".]]
** While less likely, that one could ''also'' be a reference to TerryPratchett's ''TheCarpetPeople'', where a skilled fighter who is nonetheless clueless with swords is told "The blunt end goes in your hand and the sharp end goes in the other person... don't get them mixed up."
* Scapegrace, as a zombie [[spoiler: head in a jar]], notes that he had heard someone once say [[DoctorWho fezzes were cool.]]
* Ghastly giving relationship advice to [[spoiler: Fletcher]] in the chapter 'The Wisdom of Leonard Cohen'. He quotes [[LeonardCohen I'm Your Man]], saying it's something a friend of his once said.
* In The Maleficent Seven, Tanith and Sanguine mention that they are both Harry Potter fans while ridiculing a Necromancer who uses an actual wand for magic. They're worried it might become a stereotype.
** The same Necromancer says, [[LordOfTheRings "You shall not pass!"]] when he confronts them.
* In the same book, Tanith quotes {{The Untouchables}} and is rather annoyed when nobody else gets the reference.
* Another in The Maleficent Seven, Saracen Rue [[Comicbook/{{X-Factor}} knows stuff]].
* "I watch things now. Shows. {{Gilmore Girls}}. Have you seen it? I watch the reruns on television. They talk so fast on that show. I've never known anyone to talk so fast, except on {{The West Wing}}. {{The Wire}}. I've watched that as well. Harrowing stuff, but I watched it. And {{Series/Buffy The Vampire Slayer}}. Now there was a show. Series/{{Firefly}}, too. Cancelled before its time, that one."
* Darquesse references Spiderman's WithGreatPowerComesGreatResponsibility. She denies it immediately.
* The Maleficent Seven references [[Film/RaidersOfTheLostArk Indiana Jones; Raiders of the Lost Ark]]'s top men quote, with "Top. People."
* Another TV Tropes shout-out comes at the beginning of ''Kingdom of the Wicked'' with a discussion on [[SchrodingersButterfly whether a character is an insane man who thinks he's a butterfly or an insane butterfly who thinks he's a man.]]
