Editing Cultural references in SUDA51's works

This is an ongoing list of the '''cultural references''' found in video games and other works [[SUDA51]] has contributed to. SUDA51 typically does not explain every instance of his derivative material, and as such this article attempts not to list anything that is merely speculation - the reference should be either confirmed or obvious.

==''Moonlight Syndrome''==
===Films===

==''Shirubā Jiken''==

===Corporations===
* The helicopter flying over [[mikumo 77]] has the words "GHM Tokyo" painted on its side. These three letters are used in reference to [[Shirubā Jiken|the game's]] developer, [[Grasshopper Manufacture]]. The website [[Grasshopper Network]] is another reference to the studio.

These are "Vanishing Point," "Bizarre Love Triangle," "Love Will Tear Us Apart," "Regret," "The Perfect Kiss," "World in Motion," "All the Way," "True Faith," "Shellshock," "Love Less" and "Blue Monday." "Love Will Tear Us Apart" was originally written by Joy Division, however New Order was Joy Division's successor and was the first to popularize cover versions of the song.
** The song names that appear at the conclusion of the 2017 update chapters are "Singularity" by New Order and "Dead Souls" by Joy Division.
*In the case titled Parade, there are background animations that create different words. One of the words that can form is “RADIOHEAD,” a reference to the band of the same name.

* The ''Rocky'' film series is referenced twice in [[Flower, Sun, and Rain: Murder and Mystery in Paradise|the game]]. The first time is when [[Sumio Mondo]] meets the Balboa brothers and presumes them to be boxers, likening their surname to the boxer Rocky Balboa. The second time is after Mondo realizes the poisoned [[Yayoi Hanayama]] is actually asleep, when in her dreaming she yells the name Adrian. Rocky's wife is named Adrian Pennino Balboa, causing Mondo to deduce, "She's dreaming...about ''Rocky''?"

===Music===
* The "Fat Boy Slim" weight loss device mentioned in ''[[The Lospass]]'' is named after the British DJ of the same name.

* The skeletal design of [[Extra Costume 6]] is an allusion to the outfit worn by professional wrestler La Parka.

===Sports===
* [[Alberto Ferrente]]'s story of the Italy-Brazil match is almost identical to Roberto Baggio, a real Italian soccer player who actually was one of Italy's top players in the 1994 World Cup. The Cup Match against Brazil was almost exactly as described in the game; the only difference is that when Baggio's turn for the penalty kick came, Italy was already losing and even if he scored, the next Brazil kicker had to miss to give a chance to the Italian team. However Baggio missed and the last shot was unneeded. After the match was lost, Baggio actually proclaimed, "La vita continua."
* In the epilogue of the game's third [[Request]], [[Edo Macalister]] expresses his passion for soccer, particularly the "Rangers" team. This name is used by a number of soccer teams, so it is uncertain which he is referring to.

===Video games===
* After obtaining all [[Lost and Found]] items in the Nintendo DS version of the game, Mondo gains access to [[Extra Costume 7]], the outfit worn by ''[[No More Heroes]]'' protagonist [[Travis Touchdown]], which even comes equipped with Touchdown's [[Tsubaki Mk-III]] [[beam katana]].
* As ''Flower, Sun, and Rain'' is a sequel to ''[[Shirubā Jiken]]'', several pieces of music from the latter were recycled or remixed for the game, particularly during the Requests featuring [[Yoshimitsu Koshimizu]] and [[Remy Fawzil]], and in the epilogue where Peter Bocchwinkur reveals himself to be [[Tetsuguro Kusabi]].
* Hanayama bares some resemblance to, as well as having the first name of [[Yayoi Itsushima]], a character in the video game ''[[Moonlight Syndrome]]''.

==''killer7''==
===Anime===
* [[AYAME Blackburn]] has a passion for anime cosplay and enjoys making radically cliché introduction speeches in Japanese while striking action poses like those of ''Sailor Moon'', among other magical girl-based franchises. This is more evident in a beta screenshot, where she resembles Sailor Moon.
* [[Andrei Ulmeyda|Andrei Ulmeyda's]] name and appearance refer to Andro Umeda from the show "Uchuu no Kishi Tekkaman" made by [https://en.wikipedia.org/wiki/Tatsunoko_Production Tatsunoko Production] in 1975.

* Those who turn into Heaven Smiles are said to be touched by the light that comes from the hand of God ([[Kun Lan]]). "Touched by the hand of god" is the name of a song by New Order.
** In the Japanese version, the "ASSIGNMENT"s are referred to as "NEWORDER"s.
* The characters' weapons are named after songs from various punk bands. (The weapon names were given in promotional material and aren't listed in the game or Hand in killer7). The songs to some extent represent the characters.

* Pigeons encountered by the Smith Syndicate are named after Bond girls.

** Matchmaker: "Heroes and Villains" by the Beach Boys, "Walkin' the Line" by Brian Wilson, "Barnyard" and "Catch a Wave" by the Beach Boys and "Melt Away" by Brian Wilson (Brian Wilson being one of the co-founders of the Beach Boys, so in effect they are all Beach Boys/Brian Wilson songs).

==''Contact''==
===Films===
* The icon for [[Terry]]'s [[fame]] statistic is reminiscent of the scene in ''Rocky IV'' where the titular character ends his training by running to the top of a mountain and screaming his opponent's name.
===Literature===
* The [[Professor]] occasionally mentions that he's reading a book written by Haruki Murakami, a postmodern author, postmodernism being the same self-referential style of storytelling that many of SUDA51's games employ.

* [[Jeane]] references the manga ''Miyuki'' while fast-forwarding her story.
* Shinobu's design is similar to Afro, from Afro Samurai series.

The anime is again referenced by a ''Pretty Angels'' poster adorning Touchdown's [[Living Room|living room]] wall.
* The [[Lovikov Ball]]s are a reference to the titular artifacts of ''Dragon Ball''. The game's instruction manual refers to them as being part of a wish-granting dragon - another reference to the series. Furthermore, the [[Strawberry on the Shortcake]] [[Dark Side Mode]] trance mirrors the Super Saiyan transformation in ''Dragon Ball''.
* The resonating sound of guitar chords leading into and out of the game's loading screens may have been lifted from ''Trigun'', which uses the same technique between scenes. Furthermore, the anime-only ''Trigun'' character Caine the Longshot wields a sniper rifle with an extremely long barrel and support mounts, similar to [[Speed Buster]]'s [[Buster Launcher]].
* The [[Schpeltiger]] resembles Kaneda's motorcycle in the manga ''Akira'', as well as its film adaptation.
* The theatre where [[Harvey Moiseiwitsch Volodarrskii]] performs has a similar design to the Metropolitan Opera House as it appears in ''BLOOD+''. This is worth noting as, before developing ''No More Heroes'', Grasshopper worked on a video game adaptation of ''BLOOD+'', titled ''[[BLOOD+ One Night Kiss]]''.

===Corporations===
* An [[Assassination Gig]] in the game directs Touchdown to kill the CEO of fast food chain [[Pizza Bat|Pizza Butt]], a reference to Pizza Hut.
* A "Card" sticker almost identical to the logo for Visa can be seen in the [[Motel "NO MORE HEROES"]] office window, albeit replacing Visa's upper blue portion with red, and Visa's middle white portion with blue. Above this sticker is another sticker with vague similarities to the Mastercard design.
* The [[Denki Bosatsu]] T-shirt promotes the real-life sake brewery Kikusakari Sake. [[Randall Lovikov]] can be seen holding a bottle with the same logo in his PR illustration.

* The [[Manga]] T-shirt features the logo and slogan of real-life manga culture magazine ''Megahertz''.
* [[Death Metal]]'s saber, the [[Orange II]], has a symbol which parodies Apple Inc.'s logo as it was designed by the fictitious [[Orange Computer]], also a parody of Apple Inc.
* During Ranking Battle 9 when Touchdown fights through [[Destroy Stadium]], inside vending machines on the first two floors can clearly be seen actual bags of Lay's and Doritos potato chips.
* Each time a ranked assassin is slain and the player is shown the [[United Assassins Association]] Ranking List, the player is complimented with a "Marvelous!" This may be a reference to one of the game's publishers and a frequent Grasshopper affiliate, Marvelous Interactive.
* On the menu of Destroy Stadium booth [[Purple Elephant]], "teriyaki smiles" are included as free of charge. This is a parody of McDonald's restaurants citing on their menus that smiles are free.
* Grasshopper's logo can be found in several parts of Santa Destroy, namely on the sides of newspaper dispensers and on the WGHM 86.6 FM billboard, a radio station which itself references Grasshopper's three-letter abbreviation, GHM. These initials also appear on the door of a [[Bear Hug Studio]] portable toilet.

===Television and film===
* After emerging victorious from a [[Ranking Battle]] and viewing the UAA leaderboard, when the player presses a button to continue, the screen transitions with effects similar to the hyperspace sequences seen in the original ''Star Wars'' trilogy.
* [[Beef Head]] takes its name from the surreal film ''Gokudō kyōfu dai-gekijō: Gozu''.
* Concerning [[Dark Star]], concept art on [[Trading Card No. 83]] shows that the character may have originally been planned to remove the entire upper-half of his helmet, leaving only a portion of the lower-half, further connecting him to Darth Vader, particularly his death scene in ''Star Wars Episode VI: Return of the Jedi''.
* Dark Star's revelation that he is Touchdown's father is a reference to the same revelation Darth Vader makes to Luke Skywalker in ''Star Wars Episode V: The Empire Strikes Back'', although Dark Star's claim may not be entirely true.
* [[Beam katana]]s are blatantly very similar to lightsabers from the ''Star Wars'' series, complete with the name consisting of mere synonyms. Despite the numerous ''Star Wars'' references in the game, however, SUDA51 insisted in interviews that the beam katanas were taken from ''Spaceballs'', likely as a joke.
* [[Dr. Peace]]'s weapon, a golden revolver, is a possible homage to Parkreiner's weapon in ''killer7'', which itself referenced the titular weapon in ''The Man with the Golden Gun''.
* During the Chocolate Cranberry Sundae Dark Side mode, the color of Touchdown's beam katana blade changes to red. This mirrors the most prevalent color of lightsaber used by the Sith in ''Star Wars''.
* [[Henry Cooldown]]'s coat resembles that worn by Rick Deckard in the film ''Blade Runner''.
* Jeane's history of sexual abuse and prostituting to fund her combat training is a homage to the cult film ''Thriller: A Cruel Picture''.[[File:WaynesWorldOST.png|thumb|right|200px|Top: A closeup of the shelf behind Touchdown's recliner, showing the spine and a portion of the back cover of ''Music from the Motion Picture Wayne's World''. Bottom: The back cover and spines of the soundtrack in reality.]]
* Masked bikers who taunt Touchdown en route to Dark Star's castle resemble the ''Star Wars'' character Darth Vader and are called [[T.I.E. Rider]]s, a reference to the TIE Fighter vessel in ''Star Wars''. Their motorcycles have a glass panel on the front of the body similar to the one built into the cockpit module of TIE Fighters.
* Messages left by the unseen [[Diane]] may reference ''Twin Peaks'', wherein Dale Cooper frequently leaves messages for a likewise unseen woman named Diane on his tape recorder.
* The design of Motel NO MORE HEROES is modeled after the Discount Inn in the film ''Memento''. Travis' map of Santa Destroy, with polaroid photos and accompanying location descriptions, also serves as an homage to a similar poster made by the film's protagonist. The film is, notably, also about an amnesiac man seeking vengeance for a murder. 
* Santa Destroy's baseball team, the [[Santa Destroy Warriors]], is named after the film of the same name. However, their appearance is similar to a gang in the film, the Baseball Furies, sans the corpse paint.
* [[Sylvia Christel]] calls Touchdown's cellphone before facing each assassin, telling him to "trust your Force," likely a reference to the power used in ''Star Wars'' by the Jedi and Sith.
* The color of blade emitted by beam katanas is determined by the color of the [[Power Up Part]] it is equipped with. This mirrors the color of lightsaber blades in ''Star Wars'', which are determined by the type of crystal used in the weapon's construction.
* The credit roll in the game's false ending parodies the introductions of each ''Star Wars'' film, the background song here even being entitled "Staff Wars EPISODE I."
* The death of Touchdown's mentor [[Thunder Ryu]] before his eyes is a reference to Obi-Wan Kenobi's death in ''Star Wars Episode IV: A New Hope''.
* The [[Eat]] T-shirt references the musical comedy ''The Rocky Horror Picture Show''.
* The final attained [[Job Center]] [[mission]], [[Bike Jump]], might have been based on a skit seen in ''Jackass Number Two'', where the group rides bicycles fitted with rockets off of a ramp in an effort to catapult themselves into a river.
* The [[Forest of Bewilderment]] may have been based on the dank planet Dagobah seen in ''Star Wars Episode V: The Empire Strikes Back''.
* The [[Fudo]] T-shirt references the cult martial arts documentary ''BUDO: The Art of Killing''.
* The [[Killer Lodge]] T-shirt references the ''Friday the 13th'' film series.
* The [[Looker]] T-shirt resembles the theatrical poster for the horror film ''Jeepers Creepers''.
* The monochrome [[Cranberry Chocolate Sundae]] Dark Side mode sequence and the violent executions it entails may have been inspired by the horror film ''Psycho'', particularly its pivotal shower scene, one of the most famous scenes in cinema history.
* The Schpeltiger resembles the ''Star Wars'' X-Wing vessel.
* The song "[[Hustlin' and Tusslin]]" features an excerpt from the talent show theme heard in the film ''Revenge of the Nerds''.
* The soundtrack to the comedy film ''Wayne's World'' can be found on a shelf in Touchdown's living room.
* The ''[[Superwild]]'' franchise in the game is an allusion to ''Star Wars'', with the installment ''[[Superwild: The Third Story]]'' likely referencing ''Star Wars Episode III: Revenge of the Sith'', as its name, poster and cover art seem to mirror the film. Touchdown's living room contains several ''Superwild'' toys as well, which parody R2-D2, a B1 battle droid, Jar Jar Binks, Chewbacca, two stormtrooper variants, C-3PO, Darth Maul, Luke Skywalker and Jabba the Hutt. There is also a toy of the motorcycle ridden by T.I.E. Riders, evidencing it to be part of the parody.
* The title for one of the mature videos Touchdown is prompted to return to Beef Head, ''Coffee and MILF'', may be based on the pornographic film series ''Honey and MILF''.
* The "To Be Continued" logo at the end of the game's credits is a reference to the ''Back to the Future'' film series.
* When Touchdown's closet is opened at Motel "NO MORE HEROES", a white button-up shirt with what appears to be red ink on the breast pocket can be briefly seen. This may be a reference to a recurring joke in the comedy film ''Shaun of the Dead''.
* The [[Townsend Residence]] entrance bares a strong resemblance to Tony Montana's mansion in the crime film ''Scarface''.
* Touchdown's Dark Side Mode references the "dark side of the Force" in ''Star Wars''.
* While promoting ''No More Heroes'' in the months leading to its release, SUDA51 noted a Job Center mission where Touchdown would participate in human bowling. This does not appear in the game, but the task as it was described mirrors a skit in ''Jackass: The Movie'', where the cast lines up several trash cans on a ramp bordering a lake. A well-padded Jason Acuña is then pushed forward on a rollerboard to "bowl" the "pins," the water safely breaking his impending fall.
* As inspiration for the character of Travis Touchdown, SUDA51 showed the team working on the game multiple clips from ''Jackass'' and ''Jackass: The Movie'', the most noted being a stunt in which a baby alligator bites Johnny Knoxville's nipple, clamping down for an extended period of time. He apparently showed this clip to his staff regularly, saying that "I wanted my staff to understand the kind of person that Travis is."
* The UAA Ranking Battles reference 'The Highlander' in the fact both scenarios involve combatants battling to the death , a commonly used kill in he game is decapitation, and Travis gaining more health from his victims is similar to 'the quickening', where the the victim's knowledge is transferred into the winner.
* Santa Destroy is likely based off of the concept of an extremely dysfunctional fictional American city as portrayed in animated works made in the United States as commentary and satire, some examples being that of Springfield, USA of ''The Simpsons'', O-Town of ''Rocko's Modern Life'', the titular South Park, Colorado of ''South Park'', and Highland of ''Beavis and Butthead''. Additionally, ''The Simpsons'' and ''Beavis and Butthead'' also have sold fictional town guides in the vein of how Santa Destroy has notable landmarks and aspects to its establishment.

===Geography===
* [[AREA 51]] is a reference to the nickname for a Nevada military base in in the western United States.[[File:Santa-Destroy-New-Jersey-Plates.jpg|thumb|right|200px|The vehicles in Santa Destroy sport New Jersey license plates.]]
* Despite taking place in California, all of vehicles in Santa Destroy feature New Jersey license plates.
* Destroy Stadium bears some resemblance to Yankee Stadium. Yankee Stadium's famous "facade" can be seen on the outfield walls.
* Santa Destroy is alleged to have been based on San Francisco as depicted in ''Dirty Harry'', and the post 1970's Dogtown area of Venice, Los Angeles.
* The game makes frequent wrestling references to the Canadian city of Calgary, Alberta. Calgary was formerly the home of one of the toughest wrestling training facilities, the Hart House.
* Santa Destroy's subway system in the game is similar to the subway system in New York City. One example concerns the turnstiles and signs warning passersby not to do anything to the doors. Additionally, in the [[Rounding Body Press Station|Rounding Body Press]] and [[Bow and Arrow Station|Bow and Arrow]] stations, subway schedules note the J, M and Z trains in brown circles, and the N and R trains in yellow circles. The letters and colors of these five trains match those of New York City at the time the game was released.

===Music===
* [[Destroyman]]'s theme song, "[[Stop Hanging DJs]]," is a reference to the Smiths song "Panic," which contains the refrain "Hang the DJ."
* [[Helter-Skelter]] was named after the Beatles song of the same name. Additionally, in British English the term "helter-skelter" means "in disorderly haste or confusion." While Helter-Skelter was named after the Beatles song "Helter Skelter", which refers symbolically to a spiraling amusement park slide, the dash in his name appears to have been lifted from the spelling of the dictionary term. It should however be noted that in the teaser trailer for No More Heroes, the assassin's name was spelled without the dash.
* [[Talbot]] and [[Weller]]'s names may be homages to Mick Talbot and Paul Weller of the British pop band The Style Council.
* The "AtM" logo on [[Letz Shake]]'s visor appears to be styled after the "PiL" logo used by British rock band Public Image Ltd.
* The building across the street from Beef Head has a large poster displaying "No me toques lo cojones-Grasshopper." The design of this poster is a parody of the Sex Pistols' album ''Never Mind the Bollocks, Here's the Sex Pistols''. Furthermore, a cosmetics store in western Santa Destroy is called Never Mind the Botox., also a parody of the Sex Pistols' debut.
* The Dark Side Mode attack [[Anarchy in the Galaxy]] may be a reference to the Sex Pistols song "Anarchy in the U.K."
* The [[Earthquake Generator]]'s Disaster Blaster technique may be a reference to the White Zombie song "Disaster Blaster."
* The game shares its name with that of an album by The Stranglers. A poster stating "Whatever happened to the heroes?", a lyric from the album's title track "No More Heroes", also appears throughout Santa Destroy.
* The [[Miami Bass]] T-shirt sold at AREA 51 is a reference to the American rap group 2 Live Crew.
* The name for [[Shinobu]]'s katana, the [[Three Girl Rhumba's Sword]], is a reference to the Wire song "Three Girl Rhumba."
* Glastonbury is also a reference to the popular British music festival of the same name.
* The multiple characters named Jeane are likely named after the Smiths song of the same name.

===Other===
* Concept art for Peace's revolver shows "Dr. P" engraved into the gun's handle. The "D" and "P" letters overlap each other in a manner similar to the initials "DD" on the Marvel Comics character Daredevil's costume.
* It is hinted by his dialogue that Thunder Ryu has had sex with Touchdown on some occasions, referencing the ancient practice of pederasty in some Japanese samurai castes.
* Moai statues can be found throughout Santa Destroy. Inside Destroy Stadium and the subway system, advertisements describing Moai Financial can be seen.
* Peace's name may be a pun on the homonym "piece" being a common slang term for a handgun.
* The design for the massive [[Tsubaki Mk-II]] may have been inspired by the recurrence of large weapons in Japanese mythology and popular culture.
* The design of Thunder Ryu's beam katana, the [[D.O.S.]], bares resemblance to a ''shirasaya'', a plain Japanese blade mount.
* The game frequently breaks the fourth wall. In the opening sequence, Touchdown references the average gamer's lack of patience, and then says, "For you, there, holding the Wii Remote like that? Just press the A button." In one of the final scenes of the game, Jeane says, in reference to her dark backstory, "It alone would jack up the age rating of this game even further," as well as, "What if the game gets delayed?" The reference to age rating is analogous to SUDA51's claims of making ''No More Heroes'' more violent than ''Manhunt 2'', a game which was originally rated Adults Only by the ESRB. In the game's true ending, [[Henry Cooldown]] also expresses that he "would've thought [Travis] and the player would have figured it out by now," in reference to his being Touchdown's twin brother.
* The game makes frequent references to tigers, including [[trading card]]s in the [[Mask of the Legendary Wrestler]] set, the tiger seen in the upper-right corner of the screen, and Christel's tiger-related remarks such as, "Go get 'em tiger" and "Eye of the tiger." This is due to Touchdown's Japanese name (''Torabisu'') roughly translating to "tiger." "Go get 'em Tiger" may also be a reference to a Mary Jane Watson quote in the ''Spider-Man''franchise, while "Eye of the tiger" maybe reference the Survivor song of the same name.
* The name for the King Tut shop in Santa Destroy is a reference to Tutankhamun, an Egyptian Pharaoh of the Eighteenth dynasty, during the period of Egyptian history known as the New Kingdom.
* The name for the Pirates & Ninjas shop in Santa Destroy is a reference to an Internet meme debating who would win in a fight between pirates and ninjas.
* Touchdown can be seen in an early cutscene placing his hands on a ''Pure White Lover Bizarre Jelly'' poster and uttering, "Moe" (pronounced "mo-eh"). This is a slang term frequently used by otakus, referring to a fetish or love for "cute"/"innocent" characters in video games, anime and manga.

===People===
* Christel's name is an allusion to European actress Sylvia Kristel, while her appearance is based on Scarlett Johansen.
* Destroyman's alter ego, John Harnet, bares a strong resemblance to American heavyweight mixed martial arts fighter, Josh Barnett. SUDA51 has also stated that Travis Touchdown is in part based upon Barnett. This influence is addressed in a GameTrailers video interview with SUDA51.
* Counting down to the game's release in Japan, 51 video clips were uploaded to ''No More Heroes''' Japanese website, in reference to SUDA51. Rolling Cradle Highway buses also use Road 51 to reach Speed City, another SUDA51 reference.
* [[Holly Summers]]' background may reference former model Heather Mills, who also has a prosthetic left leg. Unlike Summers however, Mills' accident is what terminated her career in modeling.
* Dr. Peace bears a strong resemblance to American actor Charles Bronson, famous for film roles in which he plays a police detective, gunfighter and hitman: all three of which apply to Dr. Peace.
* The crotch grab Letz Shake performs is reminiscent of the dance move performed by American singer Michael Jackson.
* The name for the Egbert theatre in Santa Destroy is a reference to American film critic and screenwriter Roger Ebert.
* Touchdown bears a strong resemblance to ''Jackass'' crew member Johnny Knoxville. This influence is addressed in a GameTrailers video interview.
* Volodarrskii bares a resemblance to real-life magician Criss Angel.
* When buying videos from Beef Head, Bishop quips, "Don't tell me you're passing up the latest [[Miike]]," referencing film director Takashi Miike.

===Sports===
* Concerning his name and armor design, Dark Star may be inspired by the logo of Darkstar Skateboards.
* Each region, and several businesses and streets of Santa Destroy are named after a wrestling move, such as [[Body Slam Beach]], Piledriver Realty, Rounding Body Press Station, Suplex Pizza, Tag Team Taco Twins and Avalanche Hold Street. More precisely, there are a number of references to lucha libre wrestling, such as the Luchaco gas station and the Mask of the Legendary Wrestler set of trading cards which each represent various masks of popular fictional lucha libre wrestlers.

===Video games===
* [[Heart Amplifier]]s are likely references to Heart Containers from ''The Legend of Zelda''. This is the only game in the ''No More Heroes'' series where maximum health is increased using these items.
* At various points throughout the game, usually following the death of Touchdown, a "Zaka TV" screen is displayed. Zaka TV is a news station featured in two other titles written by SUDA51, ''[[Michigan: Report from Hell]]'' and ''killer7''.
* Before telling her story, Jeanne quips, "You don't want this to be ''No More Heroes Forever'', do you?" This is a reference to ''Duke Nukem Forever'', a game which was infamous for its protracted development schedule.
* Behind Touchdown's armchair is a shelf containing many collectible items, among them a Nintendo 64 (in the HD port, it is replaced with a Genesis/Megadrive and both of its add-ons are connected to it). Also, the cartridge of the ''[[Pure White Giant Glastonbury]]'' game playable on Touchdown's television after defeating Volodarrskii resembles a Nintendo 64 cartridge.
* [[Cat Jeane]] may be a reference to the stray cat Ryo Hazuki cares for in the Dreamcast game ''Shenmue''.
* Destroyman's "Destroy Cannon" move may be based on the "Hadouken" move of ''Street Fighter''.
[[File:Kurayami-No-More-Heroes-Comparisons.png|thumb|right|200px|Top: Concept art for the cast of ''Kurayami'', released in 2006. Bottom: Concept art for the cast of ''No More Heroes'', unveiled with each issue of ''Weekly Famitsu'' in 2007.]]
* In addition to Diane's potential ''Twin Peaks'' television series reference, the ''Hitman'' video game series contains a character named Diana Burnwood whose face is also not seen.
* In the months leading up to the release of ''No More Heroes'', issues of ''Weekly Famitsu'' featured concept art for each of the game's cast grouped together. Each character was blackened, but with each issue a new character would be colorized and revealed. The manner in which the characters are grouped together is similar to the way the cast members of ''[[Kurayami#Origins as Kurayami|Kurayami]],''(a prototype of [[Shadows of the DAMNED]]) were grouped in early concept art released in 2006. Especially worth noting is the prominence of a tall, ominous character with protrusions from their head and some form of shoulder pads standing behind the rest of the characters.
* ''No More Heroes'' continues to use text-to-speech like in ''[[Shirubā Jiken]]'' and ''killer7'', particularly the Mac "Whisper" voice.
* The electronics manufacturer [[ISZKTEC]] is mentioned in the manual, previously making a much larger appearance in ''killer7''.
* The Forest of Bewilderment may be a reference to the ''Legend of Zelda'' series' Lost Woods, forests with the same maze-like quality.
* The game makes several references to SUDA51's previous effort, ''killer7''. Examples include [[Bad Girl]]'s fridge in the Destroy Stadium basement containing a "[[Chiller7]]" label, "Bad Girl" being a slogan seen on one of [[Travis Bell]]'s muscle shirts, techniques taught to Touchdown by [[Randall Lovikov]] being named after the likenesses of Smith Syndicate members, and [[Travis Touchdown's attacker]] being a homage to Parkreiner. Also, lucha libre masks Touchdown encounters before each Ranking Battle contain letters signed "[[M.S.]]", which may refer to [[Mask de Smith]], an assassin and wrestler in ''killer7''. It is somewhat unclear how many of these are mere homages and how many are intended to be plot connections placing ''No More Heroes'' in the world of [[Kill the Past]].
* The game's minimap was likely inspired by the map used in the ''Grand Theft Auto'' series.
* The game's pause menu graphically resembles that of a second generation video game console. The ''Pure White Giant Glastonbury'' game playable on Touchdown's television assumes the appearance of a second generation shoot 'em up game as well.
* The game's title screen plays a four-note fanfare of the chime heard after solving a puzzle in ''[[Flower, Sun, and Rain]]''.
* The left and right margins in ''Pure White Giant Glastonbury'' may reference those seen in the video game ''Mobile Light Force''.
* The name for Thunder Ryu's beam katana, the primitive D.O.S., is a reference to the family of operating systems for IBM compatible PCs marketed between 1981 and 1995.
* The purpose of the [[Accelerator]] may have been based on the Stone of Agony item in the video game ''The Legend of Zelda: Ocarina of Time'', which also causes the controller to vibrate in the presence of buried secrets.
* How Travis talked to himself during his bout with Death Metal is a reference to the ramblings of the Prince, seen in Prince of Persia.
* The visor Letz Shake dons during the Disaster Blaster's initiation phase resembles Nintendo's Virtual Boy, while the Earthquake Generator contains engines that refer to the PlayStation 3's cell microprocessor and the Xbox 360's Trinity engine. Concept art on [[Trading Card No. 72]] shows another peripheral Shake was meant to don during the Disaster Blaster sequence, a glove with a design similar to a Virtual Boy controller.
* There are a number of references to ''Fire Pro Wrestling'', a game series SUDA51 had previously directed. A comic in the game's Japanese instruction manual references the fictional ''Super Fire Pro Wrestling Lucha Libres''. The [[manager of Job Center]] wears a GONGS T-shirt, GONGS being the wrestling federation in ''Fire Pro Wrestling'', based on the real-life federation RINGS. The "Mask de Panther" mentioned in [[Beef Head]]'s ''Video Vol.1'' and ''Video Vol.3'' reference the name given to recurring character Tiger Mask in American releases, "Tiger Mask" itself being a reference to the 1968 manga ''Tiger Mask''. Finally, Touchdown's mentor Thunder Ryu is a character lifted from the ''Fire Pro Wrestling'' series, originally being based on the real-life wrestler Genichiro Tenryu. [[Burger Suplex]] advertises a Super Fire Hamburger Special, a reference to ''[[Super Fire Prowrestling Special]]'', SUDA51's first video game effort.
* Three trading cards in the game are of professional wrestlers El Flor, El Sol and El Lluvia, meaning The Flower, The Sun and The Rain. Also, a Japanese two-page print advertisement for ''No More Heroes'' features Christel sunbathing in a bikini without a top, sporting the letters "F.S.R." while a plane flew by in the background. These are obvious references to ''Flower, Sun, and Rain''.
* Helter Skelter's appearance is similar to Sephiroth, the main villain of ''Final Fantasy VII''
* Dark Side Mode's use of extreme screen filters during its activation is reminiscent of the use of Soul Sphere powerups, specifically the Invincibility Soul Spheres from the original installments of the classic first person shooter ''Doom''.

==''No More Heroes 2: Desperate Struggle''==
===Anime and manga===
* After being vertically bisected in the first installment, Destroyman reappears in ''Desperate Struggle'' as an android. This situation may be a reference to the ''Dragon Ball Z'' character Frieza, who was also converted into an android after being slashed in half and left for dead.
* [[Charlie Macdonald]]'s [[Santa Death Parade]] resembles Dekabutsu in ''Tengen Toppa Gurren Lagann''. Like Dekabutsu, it also contains its face in its chest, as well as a head.
* [[Cloe Walsh]]'s predicament may have been inspired by the ''Elfen Lied'' character Lucy, who is also bound in a maximum security cell.
* [[Mimmy]] bears resemblance to Vocaloid avatar Rin Kagamine.
* While the three protagonists of ''Pure White Lover Bizarre Jelly'' in ''No More Heroes'' were based on ''Pretty Cure'', two new characters were added for ''Bizarre Jelly 5'' in ''Desperate Struggle'', now based on ''Yes! Pretty Cure 5''. These are [[Gooseberry]] and [[Nutberry]].

===Corporations===
* Pizza Bat is a reference to the restaurant chain Pizza Hut, although this allusion is more obvious in ''No More Heroes'', where the fictional chain is referred to as "Pizza Butt."

===Films===
[[File:PB-Batarang.png|thumb|right|200px|Jasper Batt Jr. attacks Travis Touchdown with batarangs. Above the doorway in Batt's office can also be seen a logo inspired by ''Batman''.]]
* [[Alice Twilight]]'s [[ASURA-6]] jetpack gives her the resemblance of ''Star Wars''<nowiki>'</nowiki> General Grievous, who could wield four lightsabers at once.
* As SUDA51 is a known fan of ''Batman'', Walsh may reference the ''Batman and Robin'' incarnation of the character Poison Ivy. Both share red hair, a seductive personality, control poisonous fumes and use kissing as a weapon. Poison Ivy also returns to life in a similar manner to how Walsh is released by Touchdown.
* In his Ranking Battle against [[Matt Helms]], Touchdown remarks that "It's time for some pro bono ghost-bustin'!" This is an allusion to ''Ghostbusters''.
* In the game's teaser trailer, Touchdown declares "I'll be back!" before engaging a battle with Twilight. This is likely a reference to the ''Terminator'' film series' catchphrase "I'll be back." Furthermore, Touchdown's words here initiate a clip of music similar to that of the ''Terminator'' scores.
* In the job [[Getting Trashed]], the top part of a silo behind the building is shaped after the top-half of the Death Star.
* [[Kimmy]] wields a double-bladed beam katana. This weapon may have been inspired by the dual-bladed lightsaber used by Darth Maul in ''Star Wars Episode I: The Phantom Menace''.
* SUDA51 named ''Desperate Struggle'' after the yakuza film ''Battles Without Honor and Humanity: Hiroshima Deathmatch''.
* The black glove Shinobu wears over her right hand, which Touchdown severed in ''No More Heroes'', may be a reference to the glove Luke Skywalker wears over his hand in ''Star Wars Episode VI: Return of the Jedi'', which had also been previously severed.
* The scene where Touchdown encounters [[Nathan Copeland]] is visually reminiscent of a scene in the Alejandro Jodorowsky film ''The Holy Mountain''.<ref>[http://thecia.com.au/reviews/h/images/holy-mountain-la-montana-sagrada-1.jpg The CIA: Complete Internet Database]</ref>
* The ''Superwild''-based T.I.E. motorcycle, which first appeared in ''No More Heroes'', is a reference to the TIE Fighter vessel in ''Star Wars''. These motorcycles have a glass panel on the front of the body similar to the one built into the cockpit module of TIE Fighters.
* The theme song for Motel "NO MORE HEROES" in ''Desperate Struggle'' is called "[[Bates]]." This is a reference to the Bates Motel in the film ''Psycho''.
* The way Christel relates the story of ''Desperate Struggle'' through a glass window in a stripping booth is a reference to a famous scene in the film ''Paris, Texas'', which SUDA51 has frequently cited as his favorite film.
* When activating Dark Side Mode, Touchdown utters, "Be one with the Force."

===Locations===
* [[Prison Island]] is likely a reference to the former prison island Alcatraz, also located in California.

===Other===
* [[Jasper Batt Jr.]] attacks Touchdown with batarangs. In addition to this, above a doorway in Batt's office is an emblem inspired by the ''Batman'' logo.
* In the most obvious reference to ties between East and West in a Grasshopper title since ''killer7'', the American Touchdown, associated with the tiger, faces off against the Japanese [[Ryuji]], associated with the dragon, during Ranking Battle 7.
* [[Margaret Moonlight]] wields [[Le croissant du ange]], a pair of sniper rifles modeled after scythes, and believes her qualities not to be unlike those of the Grim Reaper. Moonlight is the fourth-ranked assassin in the game, the Japanese number four being ''shi'', another word for "death."
* The term [[wikipedia:Uncanny Valley|Uncanny Valley]] is a hypothesis in the field of robotics which holds that when robots and other facsimiles of humans look and act almost, but not perfectly, like actual humans, it causes a response of revulsion among human observers. Considering [[Uncanny Valley]]'s role as a clothing brand in the newly monopolized Santa Destroy, this is likely a jab at modern consumerism and conformity brought on by conglomeration.
* Touchdown faces off against [[Ryuji]] at [[Ironclaw Point]] at sunset. At this point in the story Touchdown has recently gained the beam katana pair [[ROSE NASTY]], while Ryuji enters the battle wielding a single, large beam katana. This encounter could have been heavily based on the famous duel of Miyamoto Mushashi and Sasaki Kojirō.
* [[Vladimir Taktarov]] wears an insignia similar to the ''Star Trek'' logo on his chest.
* Walsh has the ability to generate a high-pitched sonic "scream" for a variety of effects, potentially referencing the ''Thunderbolts'' character Screaming Mimi or DC Comics' Black Canary.
* Ashuras are a fanatical tier of deities found in Hindu and Buddhist mythology, most popularly known as multi-limbed and faced beings common in popular fiction, but are known in their respective religions as belligerent, indulgent, and materialistically inclined beings, notable for their anger, harsh temperaments and ignorance, ranking above humans yet lacked the means to have truly incarnated as devas and Bodhisattvas, seeking transcendent power and enlightenment through their own methods. Being born as an Ashura is also seen as one of the four unhappy births in Buddhist thought, representative of a human being driven by anger, always seeking violence, addicted to force and power, and incapable of making peaceful solutions and answers; despite their rankings above humankind, the fate of being born an Ashura is considered a path of suffering worse than human life, their lives always filled with neverending carnage and constant conflict. Considering the series' own focus on ultraviolence, assassins, and unrestrained fighting to the death, Alice may symbolically represent these demi-godly beings, considering her rank in the UAA, her weapon of choice, extraordinary combat skills, her outlook on life, and the ascetics training she has taken before her fight with Travis.
* In a cutscene, Sylvia says, "Anything less would be uncivilized."  This sentence was used as the tagline in a commercial for Right Guard deodorant.
* The theming for Travis' character to be associated with a tiger, is a somewhat popular theming derived from the influential Chinese classic tale ''The Tiger of Chao-Cheng'', where a feral tiger reforms in penance of his deed of devouring the son of an elderly woman; derived from this, often incorporated into Japanese literature, tiger themed characters start off antagonistic, yet grow as characters to be heroic protagonists in their own right after righting their wrongs. More modern examples would be the Street Fighter character Sagat and Rurouni Kenshin Jinchu Arc villain Yukishiro Enishi. 
** The idea of Travis taking down the corrupted town of Santa Destroy under the influence of Pizza Batt is likely a nod to the Confucian proverb "Bad governance is worse than a rampaging tiger."

===People===
* After Shinbou's phone call with Christel in the cemetery, a gravestone bearing the name Hart is prominently shown. This may be a reference to wrestler Owen Hart, who had an untimely death during a pay-per-view event.
* In the game's teaser trailer, a row of buildings can be seen, topped by flags of Santa Destroy. Each building is numbered, with one building labeled "51," in reference to SUDA51.
* Japanese filmmaker Takashi Miike makes a cameo appearance as [[Miike|a friend]] of Bishop who relays the ROSE NASTY to Shinobu, which are to be delivered to Touchdown.
* The clothing store [[Airport 51]] is also based on SUDA51's name as well as the previous store AREA 51.
* Touchdown begins the game ranked 51st in the United Assassins Association, another reference to SUDA51's nickname.
* Touchdown's keyring can be heard jingling as he walks. This is reportedly based on one of SUDA51's habits.<ref name="1UP-1-2">[http://www.1up.com/do/previewPage?pager.offset=1&cId=3176090&p= Two new playable characters, the final word on MotionPlus, Classic Controller support, obscure trivia, and exclusive new screenshots.] Matt Leone. 1UP.com. September 17, 2009.</ref>

===Video games===
* A common thug in the game wears the same suit as Garcian in ''killer7''.
* One of the shops in Santa Destroy is named ''Samantha's Soap Shop''. This is likely a reference to [[Samantha Sitbon]] from ''killer7''.
* Prison Island is a nod to the gameplay of ''Metal Gear Solid''.
* [[Skelter Helter]] may have been based on Cloud Strife of Final Fantasy VII, wearing clothes similar in style and brandishing a beam katana similar to his Buster Sword.
* The brothel establishment where Touchdown visits Christel is called [[Heaven's Smile]], a reference to the [[Heaven Smile]] enemies found in ''killer7''.
* The increasing length of the Peony may be a reference to the ''Final Fantasy VI'' Ultima Weapon, a growing energy sword.
* The exceedingly long [[Peony]] beam katana model may have been inspired by the ''Final Fantasy VII'' Masamune, and like its wielder Sephiroth, Touchdown is capable of wielding it single-handedly.
* Twilight bares a strong resemblance to the ''Kingdom Hearts'' character Marluxia.
* After the player kills or defeats a boss, the kanji for "Dead" will appear on-screen. This is a reference to the death screen for ''killer7''.
* The automobile repair shop ''Great Nick Auto'' is a reference to the ''Grand Theft Auto'' series.
* Pizza Butt being rechristened to Pizza Batt may likely be in reference to the ''Mother/Earthbound'' RPG series and the antagonist Pokey Minch; his name of Pokey is his United States variant of his name, while his originating material has him named as Porky, as a play onto his weight and pudgy appearance. Considering how ''No More Heroes 2'' is a sequel, ''Mother 3/Earthbound 2'' features an animal themed antagonistic organization as a play on Porky's name, in this case being the Pigmask Army, and whose story delves into themes of the human condition, societal perspectives of contention, and the meaning of happiness.
* Alternately, with how the first ''No More Heroes'' has references to the anime and manga series ''Trigun'', ''Desperate Struggle'' likely draws more from the Yasuhiro Nightow video game series ''Gungrave''; both feature more vastly darker themes of revenge, further descent into corruption and the criminal underworld, and themes of "karma from beyond the grave". Loosely, Pizza Batt thugs draw similarity to Orgmen, the dress suited alien drug doped thugs of the central antagonist organization Syndicate who were also designed with a single "bat wing" to signify their conversion, and the game's climax takes place atop a tower.

==''Shadows of the DAMNED''==
=== Film and television===
* [[Act 2-4]]'s title, "Riders of the Lost Heart" is a reference to the ''Indiana Jones'' film ''Raiders of the Lost Ark''.
* [[Christopher]] sometimes proclaims, "Who you gonna call? Chris-topher!" to the tun of the ''Ghostbusters'' theme, which he proceeds to hum.
* [[Garcia Hotspur]]'s quote in [[Act 4-5]], "I'm a Mexi-can, [[Johnson]], not a Mexi-can't," is derived from the film ''Once Upon a Time in Mexico''.
* The credit roll disclaimer that no demons were harmed during production, bar [[George Reed]]'s horse getting sick and a [[Goat Lamp]] being shot is similar to the disclaimer at the end of ''The Simpsons'' episode "Dog of Death."
* The title of [[Act 3-3]], "As Evil as Dead", is a reference to the ''Evil Dead'' franchise. Other references include Johnson likening their predicament to a film when he and Hotspur retreat into a cabin, the demon trying to escape from the basement and Hotspur's quote, "My God, how do we stop them?"

===Music===
* Hotspur compares the conclusion of ''[[The Legend of Stinky Crow]]'' to an Alanis Morissette song.
* The words on Hotspur's jacket, "Love will tear us apart" and "Dead souls" are Joy Division songs.

===Other===
* At the library entrance in "[[Ghost Hunter]]," Johnson suggests that Hotspur "Dewey-decimate" his foes. This references the Dewey Decimal Classification.

===People===
* SUDA51 is referenced shortly after slaying [[Maras Grim]], by a signpost reading "51 Bridge Road."

===Video games===
* Characters named [[Paula (Michigan: Report from Hell)|Paula]] and [[Justine (Michigan: Report from Hell)|Justine]] previously appeared in another Grasshopper title, ''Michigan: Report from Hell'', contrasting the ''Shadows of the DAMNED'' characters [[Paula]] and [[Justine Divangelo]].
* Paula bares several similarities to the ''Devil May Cry'' character Trish. Both are beautiful women who suddenly appear to their respective protagonist (Dante in ''Devil May Cry'' and Hotspur in ''Shadows of the DAMNED''), try to kill the protagonist on several occassions, are revealed to be powerful demons serving the main antagonist (Mundus in ''Devil May Cry'' and [[Fleming Whatshisfaces]] in ''Shadows of the DAMNED'') and have origins that are left largely ambiguous.
* In contrast to Trish, Paula shares some qualities with ''Devil May Cry 3''<nowiki>'</nowiki>s Lady, as both characters possess similar hairstyles and heterochromia.
* The six wings of Paula's demonic form are a reference to the Seraphim, a race of angels who were said to appear as six-winged humans and were considered to be the angels closest to Yahweh. Coincidentally, Lucifer and several other demons were said to be Seraphim prior to their falls from grace.
* In the first stage, Johnson is puzzled by a diagram found on a building wall, which references the trajectory figures from ''Portal''.
* The titles for Acts [[Act 4-2|4-2]] and [[Act 4-4|4-4]] are "Great Demon World Village" and "Great Demon World Forest." The Japanese title for the video game ''Ghosts n' Goblins'' is ''Makaimura'', or "Demon World Village." The stage map seen throughout ''Shadows of the DAMNED'' also resembles the collage of stages in the ''Ghouls n' Ghosts'' games. Like ''Ghouls n' Ghosts''<nowiki>'</nowiki> Arthur, Hotspur too is stripped of his clothing as he takes damage.
*[[Garcia Hotspur]] is similar to Dante from Devil May Cry in the fact that they both use guns, have a similarity in appearence and have some sort of demonic force attributed to them. Garcia has Johnson, a demon skull that turns into his weapons and Dante has demon blood from Sparda, a demon warrior who is also his father.

==''No More Heroes: Heroes Paradise''==
This section only contains material that is not referenced in the original Wii version of ''No More Heroes''. For more references, see [[#No More Heroes|the ''No More Heroes'' section]] above.

===People===
* ''[[No More Heroes: Heroes Paradise|Heroes' Paradise]]'' contains a number of references to SUDA51. [[Score Attack]]'s Network Rankings list the top 51 PlayStation Network accounts with the most points. Among [[No More Heroes: Heroes' Paradise trophies and achievements|the game's 51 trophies]] are rewards for killing [[Looks like you're getting used to killing|51]], [[Keep slaughtering your way to the top!|510]] and [[What a massacre! You're awesome, Travis!|5100]] thugs and destroying [[The association is getting damage claims, you know?|51]] and [[I'm deducting the compensation from your prize money|510]] objects using the Schpeltiger.

===Video games===
* The shirt Bad Girl wears in Very Sweet sports the logo for ''Heroes'', an early name ''No More Heroes'' was given during development.

==''Evangerion Shin Gekijōban -Saundo Inpakuto-''==
===Anime===
* The gameplay of ''Saundo Inpakuto'' seems to be entirely based on the premise of the ninth episode of ''Neon Genesis Evangelion'', "Moment and Heart Together," where both [[Shinji Ikari]] and [[Asuka Langley Soryu]] are required to defeat the angel Israfel in synchronization through rhythm via dance and music.
===Music===
* During one of the sequences of Teardrop, the telephone wires and background buildings appear on-screen in beat-sync with a particular drumbeat.  Both are references to the video for Star Guitar by The Chemical Brothers

==''Sine Mora''==
===Corporations===

* The blast generated by [[Ronotra Koss]]' special weapon, the Punk Spirit, is based on the current [[Grasshopper Manufacture]] logo.
===Video games===
[[File:SineMora06.jpg|thumb|right|200px|''Black Knight Sword'', advertised in an early ''Sine Mora'' screenshot.]]

* [[Domus]] is alternatively referred to as "Ssob Pu Dekcuf," much like the Moor Pu Deckuf zone in ''Shadows of the DAMNED''. When reversed these respectively spell "Fucked Up Boss" and "Fucked Up Room."

* The [[Shiro Costume]] was borrowed from the anime ''Deadman Wonderland''.
* After jumping on zombies in [[San Romero High School]], the camera changes to Juliet's front with the zombies behind. She then says "You're already dead." before the zombies explode. This is no doubt a reference to the anime ''Hokuto no Ken''.

===Corporations===
* After slaying [[Lewis Legend]], Starling insults [[Swan]], calling him a "whiny, Myspace-haired jerk."
* [[Juliet Starling]] believes she may be a Facebook friend of the zombie outbreak's perpetrator, whom Starling surmises might have used the social website to learn her birthday so as to plan the attack for that date.

* During the fight with Legend, Carlyle wonders if Ashton Kutcher will come out admit he and Starling have been punk'd.
* Fulci Fun Center borrows its name from Lucio Fulci, an Italian director famous in the zombie genre for helming the film ''Zombi 2''.
* Killabilly takes his appearance after Elvis Presley.
* M. Night Shyamalan is listed among Killabilly's interests.
* San Romero High School is a reference to zombie film pioneer George A. Romero. An early named zombie, George, may also be a nod to the filmmaker.
* Seth Green is referenced with the character Anastasia, who is said to have felt a spiritual connection with the actor, breaking into his house to play with his action figures.
* Starling continually mistakes Josey's speaking through Auto-Tune as an imitation of Stephen Hawking.
* Starling is referred to as "the Babe Ruth" of Zombie Baseball.
* Starling sarcastically calls [[Swan]] and Legend "Mary-Kate and Ashley," in reference to the Olsen twins.
* Starling's [[Pin-up Outfit]] is an allusion to American model Bettie Page.
* The [[Little Jimmy Urine Outfit]] is inspired by the looks of musician Jimmy Urine, who voices Zed in the game.
* The trophy [[JULIET51]] references SUDA51. Furthermore, on PlayStation 3, players who obtain the game's 50 trophies are awarded an additional platinum trophy, bringing the total to 51. As with ''Shadows of the DAMNED'' and ''Heroes' Paradise'', this is likely an unintentional reference, as there are not 51 achievements in the Xbox 360 version.
* When the zombie [[Stephanie]] is slain, she cries, "Now I hate you more than Carrot Top," referencing the comedian.

===Video games===
* [[DokuroMan|DokuroMen]] share a resemblance with Pac-Man, and are even encountered in a similar-styled maze.
* ''Lollipop Chainsaw'' shares several elements with Grasshopper's earlier efforts, such as Starling's incoming phone calls and the death of her mentor, much like the cost of Thunder Ryu's life during Travis Touchdown's quest to become number one in ''No More Heroes''. Starling's alliance with a disembodied head is also akin to Garcia Hotspur's partnership with the floating skull, Johnson, in ''Shadows of the DAMNED''. Zed uses special attacks previously displayed by Henry Cooldown in ''No More Heroes'', such as his spinning jump drop and a dashing thrust; he also sports a similar look to the one seen in Letz Shake's concept art, with a shaved towering red mohawk cut atop his pale face. Starling's Nick Popper shooting mode is much like Touchdown's Blueberry Cheese Brownie, in that movement becomes limited, firerate is slow and a similar camera angle is used.
* Super Mario is referenced with Caryle's quip about "a little dude in a red cap and blue overalls."
* The ''Tricolour'' arcade cabinet has a similar playing field as that seen in ''Q*bert''.
* When Starling and Carlyle become part of Josey's video game ''Funk Patrol'', they are essentially trapped in a ''Pac-Man'' maze. Upon noticing this, Carlyle notes that, "things just got all Commodore 64," Starling retorting that their foe, a DokuroMan, thinks they're "blue ghosts." The third game they enter is a variation of ''Breakout''.

==''Killer Is Dead''==
===Music===
* ''[[Killer Is Dead]]'' borrows its title from the Smiths album ''The Queen Is Dead''. The first scene of the game fades into the sight of a chessboard with a fallen Queen piece.
* Most of the chapters are name "The Man Who ''Did Something''". This might be a reference to David Bowie's album "The Man Who Sold the World".
* "Dark Side of the Moon" is a reference to the ''Pink Floyd'' album of the same name. 
* The character "Moon River" is a reference to the song of the same name sung by Audrey Hepburn. Coincidentally, Moon River also shares physical characteristics to Hepburn including her hair style and color, body type, facial structure, clothing and jewelry. 
* The achievement "Ticket to Infinity" may possibly be a reference to Electric Light Orchestra's song ''Ticket to the Moon'', as the moon is a reoccurring location in the game. 

==''Tsukikage no Tokio''==
===Anime and manga===
* Tokio's power of the Moon begins by stopping time and inverting the world's colors, much like Dio's "The World" in ''Jojo's Bizarre Adventure''.
* According to the concept art, one of the inspirations for Jam's design was Luna from ''Sailor Moon''.
===Television and film===
* Two other inspirations for Jam's design, according to the concept art, are the western cartoon ''Kid vs. Kat'', and Si and Am from ''Lady and the Tramp''.

==''Kurayami Dance''==
===Literature===
* The story's origins lie in early drafts for ''[[Shadows of the DAMNED]]'', which were based on Franz Kafka's novel ''The Castle''. The character [[G]]'s name parallels that of the protagonist of ''The Castle'', K.

==''Let It Die''==

=== Anime and manga ===
* Several aspects of the game are reminiscent of the manga series ''Dorohedoro''. Not only does Uncle Death resemble the character Ebisu, but both have mushrooms as an important item and vast amounts of gore.
** Q Hayashida has previously worked with Grasshopper before for concept art. Specifically, she designed various bosses for ''Shadows of the DAMNED''.

===Films===
* [[Tetsuo]] is likely named after ''Tetsuo: The Iron Man''.
===Music===
* One of the games advertised in the [[Hated Arcade]] is "Bigmouth Strikes Again", which is the name of a Smiths song.
* The fountain in the center of the [[Waiting Room]] is called the Vanishing Point, which is the name of a song by New Order; it was also the first New Order song to be referenced in ''Shirubā Jiken''.
===Video games===
* [[Uncle Death]] refers to the game ''Rogue'' when he calls ''Let It Die'' a roguelike, which is a term referring to any game that is "like" "Rogue", i.e. following the basic design concepts that were codified by ''Rogue'' (random area generation and permadeath).

==''Travis Strikes Again: No More Heroes''==
===Anime===
* When Travis and Badman use the [[Travisman Formation]] Skill Chip, they merge using the fusion dance commonly seen in ''Dragon Ball Z'', even shouting "''henshin''" and "fusion" while they perform the ritual.
* Travis tells [[Brian Buster Jr.]] that he's "no 'Gandum'<!--exact spelling--> pilot or whatever," referencing the ''Gundam'' franchise.
* ''Gundam'' is also referenced by the [[Gearbox]]es found in ''[[Golden Dragon GP]]''. Gearbox Z, Gearbox ZZ and Gearbox ''v'' seemingly refer to Zeta Gundam, ZZ Gundam and ''v'' Gundam respectively. In this respect, the [[∀ Chip]] may also be a nod to the anime series ''∀ Gundam''.

=== Comics ===
* When Travis throws [[Death Driver]]s at the conclusion of each fight, one of his taunts is, "It's clobbering time!" This is a reference to the Fantastic Four character Thing's catchphrase.

===Corporations===
* In the game's trailer, Touchdown's trailer contains a "20th Anniversary Marvelous!" decal. This alludes to publisher Marvelous Entertainment having recently celebrated its twentieth anniversary on June 25, 2017.
* Grasshopper Manufacture references itself when the ''Hotline Miami'' Carl Mask appears on Touchdown's television. This locust mask resembles a grasshopper.
* Nintendo is referenced in Touchdown's trailer where a T-shirt hangs and reads, "Flick of the Switch." A gloved hand also appears on the shirt, performing a flicking gesture. This references Mario and the Nintendo Switch console.
* [[Hazure]] is the antonym of Atari.

===Film===
*The 1999 David Cronenberg movie ''Existenz'' was stated by SUDA51 to be the inspiration for ''Travis Strikes Again''. The film focuses on virtual reality format video games being played and experienced through jacking in plugs through the spine, and the concepts of the perception of reality and mankind's interaction with technology.

===Music===
* ''Travis Strikes Again'' is named after "Bigmouth Strikes Again" by The Smiths.

===Video games===
* The Travis Strikes Back scenarios are presented in a manner inspired by the Film Window layout in ''The Silver Case'', this time using green monochrome graphics reminiscent of the early days of computing.
* A number of video games are directly referenced by T-shirts in the game. These are ''Hyper Light Drifter'', ''Dead Cells'', ''Mulaka'', ''Earth Atlantis'', ''Dandara'', ''The American Dream'', ''Fallen Legion'', ''2064: Read Only Memories'', ''Hollow Knight'', ''Furi'', ''De Mambo'', ''Brawlout'', ''SteamWorld Dig 2'', ''VA-11 Hall-A: Cyberpunk Bartender Action'', ''Children of Zodiarcs'', ''Stifled'', ''Morphies Law'', ''Blazing Chrome'', ''Pocket Rumble'', ''Floor Kids'', ''BIT.TRIP RUNNER'', ''Disco Elysium'', ''Double Kick Heroes'', ''Treachery in Beatdown City'', ''Wargroove'', ''Pato Box'', ''SUPERHOT'', ''Papers, Please'', ''Thumper'', ''Nuclear Throne'', ''GALAK-Z'', ''Just Shapes & Beats'', ''YIIK: A Postmodern RPG'', ''Salt and Sanctuary'', ''The Stanley Parable'', ''Golf Story'', ''UNDERTALE'', ''Downwell'', ''Pikuniku'', ''APE OUT'', ''High Hell'', ''RUINER'', ''The Red Strings Club'', ''Minit'', ''The Swords of Ditto'', ''Gods Will Be Watching'', ''Absolver'', ''Mother Russia Bleeds'', ''The Messenger'', ''Hatoful Boyfriend'', ''Reigns'', ''Crossing Souls'', ''Enter the Gungeon'', ''LUFTRAUSERS'', ''Hotline Miami'', ''The Legend of Zelda: Majora's Mask'' and ''The Legend of Zelda: Majora's Mask 3D''.
* The "Death Drive!" chant at the beginning of each game is tonally similar to the "Sega!" chant popularized by the beginning of ''Sonic the Hedgehog''.
* The Vanishing Point T-Shop references the Vanishing Point fountain in ''Let It Die''.
* Touchdown is playing ''Hotline Miami'' when [[Badman]] bursts into his trailer. The game's masks are also scrolled through, with the Louie, Phil, Nigel, Earl, Jones and Carl Masks being shown on the television.
* Touchdown wears a shirt which reads, "Unreal Engine is killing wasted resources." The Unreal Engine is the game engine Grasshopper has largely used since ''Shadows of the DAMNED''.
* The basis of ''Golden Dragon GP'' was meant to be a throwback to the racing video game series ''Zero4 Champ'', although the length was shortened significantly during development.<ref name="GDGP">[https://nintendoeverything.com/suda51-on-making-travis-strikes-again-scrapped-plans-for-golden-dragon-gp-no-more-heroes-future/2/ Suda51 on making Travis Strikes Again, scrapped plans for Golden Dragon GP, No More Heroes’ future]. Brian. Nintendo Everything. February 9, 2019.</ref> 
* The backstory of the [[Death Drive]] console line was inspired by the urban legend video game ''Polybius''.
* The game's premise of Travis being sucked into a video game world harkens to similar concepts:
** The premise is reminiscent of the in game story of ''Cheetahmen'' and its originating notoriously infamous multi cart game ''Action 52'', where a gamer known as the "Action Gamemaster" is pulled into his TV and encounters the eponymous Cheetahmen, who offer to protect him in the game world. Coincidentally, ''Cheetahmen II'' was an unreleased stand alone sequel that was still in development before Active Enterprises folded its video game ventures by 1995, and had 15,000 cartridges of the unfinished game stored in a warehouse before being found and sold on the secondary market. 
** The American video game community icon and comedy figure The Angry Video Game Nerd, played by creator James Rolfe, also had a video game series based upon him via ''The Angry Video Game Nerd Adventures'' released in 2013, in where the plot revolves around him being sucked into the TV and has him journey through "shitty games" as levels, as inspired by his reviews on the aforementioned ''Action 52'' and ''Cheetahmen'' games. Travis Touchdown and the Angry Video Game Nerd also bear similarities in that they are both disgruntled and somewhat sociopathic but well meaning individuals who share interests in video games and other "geek and nerd" hobbies. Notably, Travis' design into ''Travis Strikes Back'' features him with a Power Glove inspired controller of the Death Drive II console; one of James' more popular episodes and associated elements of The Angry Video Game Nerd is that of his indepth review on the Power Glove, and with which he also uses to destroy Freddy Kruger of ''Nightmare on Elm Street'' fame in the episode prior as reference to the Nintendo scene from ''Nightmare on Elm Street: Freddy's Dead''.  
* There is a Cherry Bomb sign in the market in ''[[Electric Thunder Tiger II]]'', Joan Jett & the Blackhearts' "Cherry Bomb" being the main theme for ''Lollipop Chainsaw''.
* The police cars positioned on the outskirts of Touchdown's fight with [[Mr. Doppelganger]] display the number "2425." This is a nod to the ''[[Silver 2425]]'' collection.
