'''Kaiju Movies'''

!!!{{Franchise/Godzilla}}
* The Category scale used for the Kaiju is called "Serizawa".
** Speaking of the good doctor: Remember what humanity's last-ditch effort to stop Godzilla ended up being? [[spoiler:A small party of humans took a superweapon down to the ocean bottom and detonated it in the monster's face. At least one member of the party stayed below as part of a HeroicSacrifice.]] Sound familiar?
* A modified version of Godzilla's roar can be heard during one of the opening montage of past Kaiju attacks.
* During their introductory sequence, both Godzilla (in the 1998 American film) and the first Kaiju make landfall on bridges in traffic, both under white skies, both of which being giant CG things obscured mostly from view, and both incoming from right of frame from the sea. And then the [[{{Film.Godzilla2014}} next Godzilla movie]] does it ''again''.
* A subtle one, [[spoiler: the Aliens sending the Kaiju live near a star apparently being sucked into a black hole. One alien race in the Godzilla series (and only one to make multiple appearances) are space apes who are trying to take over the earth for the exact same reason.]]
* After the one of the Kaiju of the Hong Kong battle, Otachi, reveals that [[spoiler: holy shit she can fucking fly]] she starts making sounds very similar to King Ghidorah and Rodan.
* A scientist studying the kaiju [[Film/{{Godzilla 1998}} realizes too late that the kaiju he's studying is pregnant, after it's seemingly dead.]]
* All the kaiju have [[spoiler:two brains, just like Godzilla.]]
* The scene in Tokyo focusing on a horrified child watching the carnage is likely an homage to a particularly heart-wrenching scene in the original 1954 ''Godzilla'' of a mother and her children hiding in a Tokyo alleyway and knowing that they're all about to die.
* Newt's remarks about pollution allowing the Kaiju to survive in Earth's biosphere bring ''Godzilla vs. Hedorah'' to mind.
* When the category 5 kaiju emerges from the rift, the musical motif is very reminiscent of the motif that plays when Godzilla rises from the ocean.

!!!Other Kaiju Movies
* Leatherback's ape-like appearance and EMP may be alluding to the Toho King Kong, who had an electric grasp.
* The Knifehead kaiju looks an awful lot like Guiron from the ''Franchise/{{Gamera}}'' films.
** Some of Zigra's sharky features are also evident.
** A bit on Gamera vs. Jiger, where a team enter the body of a downed kaiju and encounter a baby monster inside.
* Raiju looks a lot like Gabora from ''Series/{{Ultraman}}''. He also evokes Tristar's Zilla with a Xenomorph mouth.
* [[spoiler: The kaiju being attracted to Earth due to pollution of the environment calls to mind several of the ''Series/{{Ultraman}}'' series, which had a similar concept in their plots.]]
* Kaiju with toxic blood may be a reference to ''Film/TheBeastFromTwentyThousandFathoms''
* Otachi, except for her tail pincer,[[spoiler: retractable wings]] and nose horns, could easily pass for the Cloverfield Monster.
* Slattern's emergence from the breach is reminiscent to the "RELEASE THE KRAKEN!" moment in 2010's ClashOfTheTitans.

'''Mecha Series'''

!!!General
* The [[http://spinoff.comicbookresources.com/wp-content/uploads/2013/03/pacific-rim-poster-coyote-tango.jpeg Jaegers posters]] were designed to resemble [[http://i.imgur.com/NBLKc3i.jpg giant robot model kit box art]].
* Gipsy Danger seems to be one to classic SuperRobot, specially to ''Anime/MazingerZ'' given it has not just RocketPunch but also [[ChestBlaster Breast Fire]]. In addition to functional nods to classic SuperRobot, and despite Del Toro's claims that he avoided visual references to established mecha, Gipsy Danger has clear influences from ''{{Gigantor}}'', the 1980 anime version specifically. Del Toro explicitly says ''Tetsujin 28-Go'' was an influence in one of the pre-release featurettes.
** Also, it has a Pilder, though we never see it operate on its own. Although it does have the classic "Pilder, on!"
** The detachable head and [[ChestBlaster blasting hole]] in its torso have an even closer resemblance to another Go Nagai super robot, ''[[KotetsuJeeg Steel Jeeg]]'' and its Spin Storm.
* Brawler Yukon, who appears in the comic, looks like a more humanoid version of the Beetle T-23 scout robot from ''[[GetterRobo Getter Robo Go]]''.
** In the same vein there's Horizon Brave, with two large shoulder mounted pods that appears during the prologue showing its construction, toy version and post-destruction. It looks a lot like [[GetterRobo Getter Poisedon]] albeit more like the tweaked design from ''Getter Robo Armeggedon''.
* Del Toro himself admitted, in a [[http://www.youtube.com/watch?v=W5va1sepKKo Japanese TV program]], that Coyote Tango and Cherno Alpha are inspired, respectively, by the Guncannon and a Zaku from ''Anime/MobileSuitGundam'', specially the former one.
** Specifically, it appears to be based on the RX-77-01 version from ''MobileSuitGundamTheOrigin'', with its 3-clawed hands, larger cannons and blue visor.
* Related to the above, Striker Eureka has "GN 000" printed on its left chestplate. This is the model number of the [[MobileSuitGundam00 0 Gundam]], which becomes more appropriate once Stacker is in the driver's seat.
* The helmets worn by Cherno Alpha's pilots bring to mind any number of sci-fi designs, but particularly seem to invoke ''[[ArmoredTrooperVotoms Votoms]]'' and ''{{Gasaraki}}'', or perhaps more pertinently the HRL pilot suits from ''[[MobileSuitGundam00 Gundam 00]]'', the HRL being the superbloc that contains Former Russia.
** Cherno Alpha's piston punch also works exactly like a Scopedog's.
* The [[spoiler: nuclear mission]] is a reference to ''{{Gunbuster}}'', particularly the descent into Buster Machine 3.
** Both works feature a mentor figure [[spoiler: [[YourDaysAreNumbered dying of radiation poisoning]]]], though it's a common enough plot device to be coincidental.
* Gipsy Danger's head [[Anime/TengenToppaGurrenLagann screws into]] the rest of the body.
** And its visor? Kamina's glasses.
** Hell, Stacker Pentecost IS Kamina. He tells Raleigh "you have no idea who the Hell I am" and his RousingSpeech at the end includes the words "we have chosen to believe not only in ourselves but each other". He channels Gendo Ikari, but deep down he's as hot-blooded as any blue-haired stunner-shades-wearing mecha pilot.
* The film is essentially an [[SpiritualLicensee adaptation]] of ''Anime/ShinkonGattaiGodannar'' , which also features a twin-pilot robot controlled by an older man who lost his partner in battle and young Japanese woman who was saved from a giant terraforming beast that rose from the ocean by a giant robot and then dedicated her life to becoming a pilot despite her guardian's disapproval. Said robot is also powered by a giant spinning turbine in the middle of its chest and uses detachable air transport to reach its deployment zone. Finally, the fact that there is an international team of robot pilots, with two of the teams being of the same origin as the ones from ''Godannar'' (One from Russia and another from China, Gipsy Danger's pilots are a composite of the Japanese and American teams, and the Australian pilots can be construed as [[ExPy expies]] of the UK Team).
* The initial treatment of the Kaiju as simply natural disasters from a dimensional rift is similar in nature to the Heterodyne entities in the anime ''Anime/DaiGuard''.
* The entire premise that Jaegers require two or more pilots who are in harmony with one another and share emotions/memories when linked? Can you say ''GenesisOfAquarion'', anybody?
** The Jaegers are piloted in the same manner in ''Film/RobotJox'', except they require two pilots.
** The shot of Gypsy Danger smacking it's fist into it's palm is taken [[http://i.imgur.com/oHKAO.gif almost shot for shot]] from ''Film/RobotJox''.
* Mori's haircut looks like a cross between [[BigO R. Dorothy Wainright]]'s and [[{{Evangelion}} Ayanami Rei]]'s. In the beginning of the film, she has blue highlights, which seem to call to Rei's blue hair.
* Crimson Typhoon's head looks very similar to a [[SuperDimensionFortressMacross VF-1A Valkyrie]]'s
* Gipsy [[{{Mechwarrior}} dumping its coolant to attack faster.]] Unlike ''Mechwarrior'', however, the coolant itself is weaponized.
* It's a bit of a stretch, but there's one crowd scene where there are two helmeted UN troopers standing to the right of Stacker Pentecost's shoulder while he delivers Important Plot. These are the only two helmeted guys clearly visible in the scene - one white guy and one black guy - and they look suspiciously like the two UN troopers guarding the base in the opening scenes of ''MuvLuvAlternative''. There are several other distinct parallels, including:
** the Kaiju are [[spoiler: bioweapons created by a race of silicon-based life forms]],
** the "blue and glowy scanning-microscope image" aesthetic of the aliens,
** the leading couple pilot a twin-seat weapon,
** like Sumika, Mako has gone through extreme trauma which causes [[spoiler: a berserker outburst at an inopportune moment]],
** a character gets [[spoiler:EatenAlive from behind in a completely unexpected manner]] while having a conversation with another character. Up until this point there has been little indication, apart from a throwaway comedy line, that the Kaiju [[spoiler: find people tasty]],
** the good guys are part of a project which is going to be cancelled by the suits in favour of a different, and less salutary, alternative,
** the leader of the good guys is a dark-skinned guy (Indian in ''Alternative'', Black Brtish in ''Rim'') who gives a rousing speech while the robots are launching on the final mission.
** All the talk about MLA and still no mention of one of the most important plot points? : in MLA, Unit 00 [[spoiler: (Sumika) connects to the BETA network every time the fluids in her body are filtered, giving her access to the BETA's plans and hive layouts. It works both ways, though: she also unconsciously sends information to the BETA, which spells grave news for the humanity.]] Sounds similar to Newt's Kaiju drifting and its consequences, doesn't it?
* Gipsy Danger's atomic generator allowing it to work in an EMP Field mirrors [[GiantRobo Giant Robo's]] ability to function within the Anti-Shizuma field. That the world's last hope lies with an outdated atomic robot also mirrors Giant Robo.
* The film explains that the invaders had once tried surveying Earth... with the dinosaurs. Perhaps an allusion to the [[GetterRobo Dinosaur Empire]]?
* Mako being rescued by Stacker in the flashback is reminiscent of Setsuna's first scene in ''{{Gundam 00}}''. "I must become Jaeger!", anyone?
* Aside from the name, Striker Eureka bears some reference to the Nirvash LFO from ''EurekaSeven''.
* [[spoiler: A interdimensional portal on the floor of the sea]] remind the Dimensional Jump from [[{{Gaiking}} Gaiking: Legend of Daikuu Maryu]].
* When Knifehead tore off Gipsy Danger's arm, the pain was felt by the pilot, similar to the Mobile Trace System in ''MobileFighterGGundam''.
* Gipsy's Danger BladeBelowTheShoulder have a function as a CoolSword and WhipSword, identical to [[PanzerWorldGalient Galient Sword]].
* The Giant Robot pilots are called [[Franchise/PowerRangers Rangers]].

!!!''NeonGenesisEvangelion''
* Before the first drift see the helmets of the suits fill with an orange/yellow fluid, a reference to LCL from Eva.
* Cocky, egotistical pilot with a chip on their shoulder and family issues, a dead mother, and constantly trying to show off to their parents. Are we talking about the second Striker Eureka pilot, or Asuka Langley Soryuu?
* A mech going berserk, thanks to its pilot's memories, and attacking (or, in Gipsy's case, nearly attacking) the control room. Absolutely nothing can stop it, not even getting unplugged. This is a reference to EVA-00 going berserk when [[spoiler:Rei]] was inside it, albeit without headbutting the control room.
* The weaponized coolant is very much straight out of "Magma Diver".
* The escape pod scene is pretty much Misato's experience of Second Impact. The first pod is even [[HomageShot shot the same]].
* The image of an aircraft carrier bearing Kaiju remains recalls a similar scene in Asuka's debut episode.
** Coincidental or not, the Japanese release dubs Mako's voice with [[MegumiHayashibara that of Rei Ayanami's]], [[LampshadeHanging lampshading the similarities]].

'''Other References'''

* Leatherback is essentially Hellboy's Sammael with a flatter face and bigger arms. He's even got a tentacle mane.

* The Jaeger AI is voiced by {{Ellen McLain}}, with Creator/{{Valve|Software}}'s blessing; The [[NeverTrustATrailer trailers]] also feature her rendition of SelfDemonstrating/GLaDOS from ''VideoGame/{{Portal}}'' and ''VideoGame/{{Portal 2}}''.
* The shoulder pauldrons on the drift suits are reminiscent of ''TabletopGame/{{Warhammer 40000}}'' [[ShouldersOfDoom space marine pauldrons]].
* The fight against Otachi has elements from the fight against Sileene in ''{{Devilman}}''.
* Hannibal pushing his knife into Newt's nose seems a reference to Roman Polanski's ''Film/{{Chinatown}}''. Notably, the scene is set in Hong Kong - a Chinese town.
* The helmets worn by the Australian and American teams have a clearly [[Music/DaftPunk French]] design to them.
* The pilot's ''suits'' both follow a similar design and are even suited up in similar fashion to the suits used by the characters of the ''VideoGame/DeadSpace'' series.
** The suits bear an even greater resemblance to the armor found in ''Franchise/MassEffect''.
* Call Dr. Newton Geiszler "Newt". [[Film/{{Aliens}} Nobody calls him "Doctor", except for his mother.]]
* Newton and Gottlieb's names are an obvious reference to another very famous pair of occasionally-feuding scientists.
* So obscure it might be a coincidence: Newton has a lot in common with ''{{Dorohedoro}}'''s Dr. Kasukabe: both are smaller-than-average [[MadScientist over-enthusiastic scientists]] with short hair, glasses, elaborate tattoos and [[AlienAutopsy a really hands-on approach]] to studying beings that can easily kill them, to the point of [[spoiler: mind-melding with / ''marrying'' the enemy, respectively]] and their research does a lot of good [[spoiler: seeing into the mind of the kaiju / knowing how evil magic-users work]] but also causes a lot of damage [[spoiler: the kaiju can read ''his'' mind / unwittingly helping the Big Bad become powerful]]. There's also [[http://www.mangainn.com/manga/chapter/61688_dorohedoro-chapter-69 this parody ]] of [[http://scienceblogs.com/tetrapodzoology/2010/11/01/science-of-godzilla-2010/ kaiju anatomy]] for Kasukabe's [[spoiler: wife, a magic-user who became a devil and can get of her "skin" for a little while]].
* [[spoiler: In Mako's flashback, Pentecost's]] suit looks a lot like either [[{{Franchise/Halo}} UNSC MJOLNIR armour]], or [[{{VideoGame/Crysis}} a helmetless Nanosuit]].
** Gipsy Danger's golden visor also resembles that of Master Chief. Note that Del Toro was considered to direct the canceled ''Halo'' movie.
*** A combination of Master Chief's visor and (best seen when viewed from an angle) [[Anime/TengenToppaGurrenLagann Kamina's glasses]].
* Newton [[spoiler: being found by the kaiju in the underground bunker]] is similar to a scene in ''WesternAnimation/ABugsLife''; incidentally, both Newton and Flick the ant are inventors with good ideas that have bad consequences (see Flick's [[NoodleIncident "tunnel-within-a-tunnel project"]] and Newton [[spoiler: drifting into the kaiju's mind and accidentally tipping off the rest of the kaiju "fleet"]]).
* The glimpse of [[spoiler: the level-5 kaiju being "assembled" when the two scientists drift into the baby kaiju's brain]] is reminiscent of [[Film/TheFifthElement Leeloo's resurrection]].
* [[MissionControl Tendo Choi]] has a VERY similar outfit to [[Series/DoctorWho the 11th Doctor]].
* When we first see one of Gipsy Danger's stat monitors, [[Series/KamenRiderDouble the left half is green and the right half is purple.]] Which is also about two people linking their minds to punch monsters.
* [[Film/ANewHope "Hey kid... don't get cocky"]]
* One of the Jaegers mentioned in the supplementary material is called [[Franchise/AssassinsCreed Eden Assassin.]]
* Some of the kaiju roars, especially near the beginning, sound like modified versions of roars from ''Film/JurassicPark''.
** The scene where the kaiju is coming to eat Dr. Geiszler in the shelter is also reminiscent of the scene where the T-Rex knocks down the restroom and eats the lawyer in ''Film/JurassicPark''.
* Little Mako's splash of blue in the midst of a grayscale city brings ''Film/SchindlersList'' to mind.
* Crimson Typhoon's eye looks similar to [[Film/TwoThousandOneASpaceOdyssey HAL's]].
** Alternatively, [[Franchise/MassEffect the geth.]]
* When Raleigh activates Gipsy Danger's nuclear reactor to [[spoiler:overload and destroy the Anteverse,]] the switch he uses to do so looks a lot like the power switches shown in ''VideoGame/MassEffect3''.
** Also, Gipsy Danger's arrival is heralded by a very loud horn, much like the Reapers, though less terrifying. Apparently, Raleigh plays it to intimidate the Kaiju, much like how the Reapers do the exact same thing. It's noted that supposedly all the Jaegers have a foghorn to intimidate the kaiju or warn nearby civilians, such as the boat.
** In fact, Gipsy Danger's design can evoke the image of an armoured Human Reaper (or a Human Reaper donning N7 armour--[[NightmareFuel think about it]]), what with the red reactor core resembling a Reaper "eye". It would roughly be around the same size as well.
* Cherno Alpha's reactor resembles [[Film/BackToTheFuture Doc Brown's]] reactor found on his [=DeLorean=].
* The explosion really comes from all over Gipsy but the camera focuses on her chest reactor. [[{{Guyver}} What other series has not just a chest blaster but a chest blaster that is way bigger than the person that fired it and is a wall of pure instant death?]]
* Striker Eureka's guns are somewhat reminiscent of the [[VideoGame/StarcraftII Odin/Thor's]] barrage.
* In a blink-and-you'll-miss-it shot during the opening montage, two Jaeger pilots are shown as guest stars on a talk show called "The Cullen Show." Possible reference to Creator/PeterCullen, perhaps?
** The pilots might be (or at least look a lot like) the Bryant twins, a doubles tennis team who are [[TwinTelepathy practically mind-melded]] (they became slightly less [[SingleMindedTwins single-minded]] when one got married).
* Drifting may-or-may-not-be an acceptable version of New Type bonding, as shown in Mobile Suit Gundam and Zeta Gundam [[StrangledByTheRedString or not.]]
* Tendo Choi's dress and mannerism make him seem like a ''Go Nagi'' character and Hannibal Chau would fit right in one of Ken Ishikawa's mangas.
* [[FreezeFrameBonus A street sign in]] the Hong Kong Bone Slums reads "Tull Street", the name taken from producer Thomas Tull.
* "Chasing The Rabit" brings ''Literature/AliceInWonderland'' to mind.
