7!''Kamen Rider''
8[[folder:20th century]]
9* ''Series/KamenRider'' (1971-73) is the first series of the ''Franchise/KamenRider'' franchise, introducing heroes Takeshi Hongo and Hayato Ichimonji, [[Main/TheMentor Tobei Tachibana]] and the evil organization Shocker led by the mysterious [[Main/BigBad Great Leader]].
10** ''Film/KamenRiderVsShocker'' (1972): The first movie in the series to tell an original story (the previous movie ''Go Go Kamen Rider'' having been a theatrical release of episode 13), released on the same day as episode 51 and set between it and 52.
11** ''Film/KamenRiderVsAmbassadorHell'' (1972): The second movie of the series to tell an original story, released and presumably set between episodes 68 & 69.
12** ''Film/KamenRiderTheFirst'' (2005): A ContinuityReboot movie of the original series, helmed by Creator/ToshikiInoue, son of the original show's head writer Masaru Igami. The remake version of Takeshi Hongo cameos in episode 14 of ''Kamen Rider Kabuto'', and returns in ''Kamen Rider Zi-O: Final Stage'', linking the film to the main continuity and its multiverse much like ''Kikaider'' and its own reboot are as described below.
13** ''Film/ShinKamenRider2023'': Another ContinuityReboot of the original series, this time helmed by Creator/HideakiAnno as part of his ''Franchise/ShinJapanHeroesUniverse'' ThematicSeries. Although there has yet to be any crossover material with the prime universe directly, it crossed over with ''Manga/CrayonShinChan'' (see Connected Properties below) in ''Shin·Kamen Rider, You Know!''.
14* ''Series/KamenRiderV3'' (1973-74) directly follows the original and reprises the aforementioned characters as the new hero fights the Great Leader's Destron organization.
15** ''Film/KamenRiderV3VSDestronMutants'' (1973): TheMovie for ''[=V3=]'', released and presumably set between episodes 22 & 23.
16** ''Film/KamenRiderTheNext'' (2007): A sequel to ''The First'' set in its continuity, adapting ''[=V3=]''. The remake version of [=V3=] appears with his predecessors in the ''Zi-O'' stage show.
17* Beyond the name "Kamen Rider", ''Series/KamenRiderX'' (1974) initially starts independent of its predecessors, with new villains. This soon changes when Tobei Tachibana, bringing with him his knowledge of the previous Riders, takes the eponymous X-Rider under his wing. A RecapEpisode of the first two shows cements the connection, reintroducing V3 then his predecessor Rider 2 as recurring characters, with the first five Kamen Riders united in TheMovie, ''Film/FiveRidersVsKingDark'' (1974).
18** Though an unauthorized production, the Thai film ''Film/HanumanAndThe5Riders'' is set in a world where the first five Kamen Riders co-exist with the god Hanuman. As this depiction of Hanuman was earlier introduced in ''Film/HanumanVs7Ultraman'', the Kamen Riders also share this world with the Ultramen.
19* ''Series/KamenRiderAmazon'' (1974-75) has no appearance from previous Riders, but does reintroduce Tobei Tachibana as ''X'' did, and a child recognises Amazon as "Kamen Rider".
20* ''Series/KamenRiderStronger'' (1975), the last series of ''Kamen Rider''’s first televised run, also includes Tobei Tachibana as well as a new band of villains led by the same Great Leader last seen in ''V3''. The first six Kamen Riders come BackForTheFinale, where the Great Leader also takes credit as TheManBehindTheMan for the bad guys in both ''X'' and ''Amazon''. The finale is followed by a RecapEpisode of the entire franchise up to that point.
21* ''Series/KamenRiderSkyrider'' (1979-80), officially known as simply ''Kamen Rider'', was originally conceived as a ContinuityReboot with a new Rider facing the Great Leader's Neo-Shocker. Instead of Tobei Tachibana, this Rider was assisted by a SuspiciouslySimilarSubstitute named Genjiro Tani. The series eventually reintroduces the first Seven Legendary Riders as recurring characters.
22** ''8 Riders VS Galaxy King'' (1980): TheMovie for Skyrider, teaming him up with the Seven Legendary Riders. Released and presumably set between episodes 24 & 25.
23* Following Skyrider was ''Series/KamenRiderSuper1'' (1980-81), featuring an independent Kamen Rider and RoguesGallery with no appearance from previous Riders (on TV that is). That said, Genjiro Tani returns as the mentor, and the first eight Riders return to help Super-1 in [[Film/KamenRiderSuper1 his movie]].
24* ''Film/BirthOfTheTenthGatherAllKamenRiders'' (1984) was a TV special which doubled as a RecapEpisode of the whole franchise and introduced the tenth Rider, ZX, who fought with his nine predecessors against the Badan Empire, led by the same Great Leader. Officially, Toei considers the special to be the first, last, and only episode of its own ''Kamen Rider ZX'' TV series, and it is included in the count leading up to ''Kamen Rider OOO''’s celebration of the 999th and 1000th episodes of the franchise.
25** ''Manga/KamenRiderSpirits'' (2001-present): An AdaptationExpansion of the ZX story, including details and answers about other Riders like explaining Riderman's UnexplainedRecovery. One of the powers ZX demonstrates in this manga became a CanonImmigrant in ''Kamen Rider Taisen'', which partially functions as a 30th anniversary celebration of the ''ZX'' special.
26* ''Series/KamenRiderBlack'' (1987-88) is, continuity-wise, totally independent of the previous Kamen Rider series. In fact, the protagonist, Kotaro Minami, coins the name himself.
27** This changes with the SequelSeries, ''Series/KamenRiderBlackRX'' (1988-89), essentially the second season of ''BLACK'' with Kotaro Minami continuing on as protagonist, which reintroduces the first ten Kamen Riders in its final episodes. The BigBad, Emperor Crisis, is also heavily implied to be the original Great Leader, sharing the same voice actor, presenting himself as the embodiment of evil and treating the assembled Riders as old enemies.
28** ''Film/KamenRiderBlackHurryToOnigashima'' (1988): TheMovie for ''BLACK'', released and presumably set between episodes 22 & 23.
29** ''Kamen Rider BLACK: Terrifying! The Phantom House of Devil Pass'' (1988): The second movie for ''BLACK'', released and presumably set between episodes 38 & 39.
30** ''Film/KamenRiderRunAllOverTheWorld'' (1989): TheMovie for ''BLACK RX'', teaming him up with his immediate predecessor (himself) via time travel. Set between episodes 23 & 24.
31** Starting with ''Kamen Rider Decade'', large crossover events tend to treat Black and Black RX as separate Riders despite both being identified as Kotaro Minami, implicitly treating one of them as the AlternateSelf that appeared in the ''Decade'' tribute episode but generally not bothering to explain how Kotaro is in two places at once.
32* In an attempt to reboot the franchise, the 1990s saw the release of three standalone films, each with a new Kamen Rider fighting new enemies.
33** ''Film/ShinKamenRiderPrologue'' (1992): AllThereInTheManual materials retroactively declare that the Foundation that serves as the GreaterScopeVillain of this movie is connected to Foundation X, which is formally introduced in ''Kamen Rider Double'' as mentioned below.
34** ''Film/KamenRiderZO'' (1993)
35** ''Film/KamenRiderJ'' (1994)
36* Then there's ''Film/KamenRiderWorld'' (1994); a short film which united ZO and J against a VillainTeamUp consisting of, as well as a monster from ''Shin'' and the baddies from ''J'', two bad guys from ''BLACK'' (that is, Black's nemesis Shadow Moon and a MonsterOfTheWeek). Thus, this film connects all three 90s movies back to the original.
37** More directly, the ''ZO VS J'' (2005) edition of ''Literature/SICHeroSaga'' crosses over its title characters.
38* From 1988 to 1990, ''The Tunnels’ Thanks to Everyone'' program had an unauthorized parody ''Series/KamenNorider'' which Toei claimed the trademark rights to in 2013. Norider eventually appeared in TheMovie for ''Kamen Rider Zi-O''.

40
41!!21st century
42Things become complicated with the revived 21st century run of ''Kamen Rider'', which continues to this day. Generally, each series has a completely different mythos/lore. The first nine are totally standalone, with small exceptions.
43
44[[folder:Heisei Era Phase 1]]
45* ''Series/KamenRiderKuuga'' (2000-01): The series once mentions a deep-voiced Professor Hongo from Jounan University, the fictional college where Takeshi Hongo studied back in the original ''Kamen Rider''.
46** The TieInNovel released in 2013 takes place 12 years after the finale and focuses on Mika Natsume becoming a prototype Kuuga.
47** ''Manga/KamenRiderKuuga'' (2015): A manga adaptation of the TV series, with a SettingUpdate to take place in 2015 [[spoiler:and an AdaptationAmalgamation with ''Kamen Rider Agito'']]. TheMovie for ''Kamen Rider Zi-O'' indicates that this manga's continuity is a ShowWithinAShow to the main universe, with the manga version of Kuuga summoned as a RefugeeFromTVLand to participate in the fight.
48* ''Series/KamenRiderAgito'' (2001-02): ''Agito'' was conceived of as a sequel to ''Kuuga'' ([[ContinuitySnarl which supposedly took place two years prior despite both shows taking place in their year of broadcast]]) but the final show has only BroadStrokes, with references to the Unidentified Lifeforms (Gurongi) and No. 4 (Kuuga) in the early episodes, the remaining legacy being SAUL (Squad against Unidentified Lifeforms) and G3, whose design is derived from Kuuga.
49** ''Film/KamenRiderAgitoProjectG4'' (2001): TheMovie for ''Agito''. Unlike other movies in the franchise, its events transpire over multiple episodes, with the beginning taking place during episode 35 and the final part taking place between episodes 46 & 47.
50** ''[[VideoGame/KamenRiderSeigiNoKeifu Kamen Rider: Genealogy of Justice]]'': A video game that acts as a story set three months after ''Agito'' crossing over the original ''Kamen Rider'' series, ''[=V3=]'', and ''BLACK'' via time travel, and notably treats ''Agito'' as taking place in 2003-2004, two years after the 2000-2001 date established as ''Kuuga''’s setting.
51* ''Series/KamenRiderRyuki'' (2002-03): Spin-off works such as the movie, TV special and others each take place within their own timeline, justified by the use of the Time Vent to constantly restart the series-spanning Rider War over and over again. The TV series finale seemingly marks a definitive end to the Rider War, resulting in the events being RetGone, though that doesn't stop the characters showing up in later crossovers.
52** ''Film/KamenRiderRyukiEpisodeFinal'' (2002): TheMovie for ''Ryuki'', taking place in one of the many time loops prior to the series but depicting an alternate finale of events that loosely follow after its version of episode 44.
53** The [[Recap/KamenRiderRyukiRyukiVsKamenRiderAgito Hyper Battle DVD special]] has Ryuki meeting the unfamiliar Agito, but it was AllJustADream.
54* ''Series/KamenRider555'' (2003-04)
55** The film ''Film/KamenRider555ParadiseLost'' (2003) is set in an alternate reality where the monstrous Orphnoch rule the world.
56** The 20th anniversary film ''Kamen Rider 555 20th: Paradise Regained'' (2023) is set primarily in the continuity of the show, ignoring the FullyAbsorbedFinale for ''555'' depicted in the ''Kamen Rider 4'' miniseries mentioned below.
57* ''Series/KamenRiderBlade'' (2004-05)
58** ''Film/KamenRiderBladeMissingAce'' (2004): TheMovie for ''Blade'', set in an AlternateContinuity where the finale ended with [[spoiler:Kazuma sealing away Hajime instead of turning himself into an Undead]]. An alternate version of THIS WhatIf scenario will serve as the setting for the Diend arc of ''Decade''.
59** ''Blade'' has two tie-in novels, the first of which ''Kamen Rider Blade “Twilight”'' (2005) has an elderly Amane Kurihara recounting what happened shortly after the end of the series. The second one released in 2013 is set 300 years after the series.
60** ''Day After Tomorrow'' (2007-08) is an ''Literature/SICHeroSaga'' story for ''Blade'' set a year after the finale.
61** ''Drama CD Kamen Rider Blade: -The Whereabout of Trump-'' (2015) is an audio drama set ten years after the finale.
62** The [[MilestoneCelebration 20th anniversary]] stage show acts as a bridge to smooth over any {{Series Continuity Error}}s between the ''Blade'' cast’s EarnYourHappyEnding in ''Zi-O''’s tribute episodes to it and the DistantFinale events depicted in the two ''Blade'' novels.
63* ''Series/KamenRiderHibiki'' (2005-06)
64** ''Film/KamenRiderHibikiAndTheSevenSenki'' (2005): TheMovie for ''Hibiki''. This one occupies a unique spot in continuity, as the bulk of it is a backstory for the series set in the Sengoku era, which is considered canon. However, the framing device of Asumu reading about it in the present day is what qualifies for NonSerialMovie, depicting its own version of Hibiki’s acquisition of his Armed Hibiki form.
65** The ''Hibiki'' novel set in the Edo era is a crossover with ''Henshin Ninja Arashi''.
66* ''Series/KamenRiderKabuto'' (2006-07): Episode 14 has a brief cameo by the remake version of Takeshi Hongo from ''Kamen Rider: The First''.
67** The film ''Film/KamenRiderKabutoGodSpeedLove'' (2006) is set in an alternate timeline but, unlike other such films, ties back to continuity as a change in the past creates the TV series timeline. Narratively, it was released before the airing of episode 28 and offers a sneak peak to the SuperMode that makes its televised debut in said episode.
68* ''Series/KamenRiderDenO'' (2007-08): Due to being a [[invoked]]CashCowFranchise, ''Den-O'' characters continue to appear in various movies after the end of their own series, most prominently a sub-franchise that spins off from the tribute episodes in ''Decade''.
69** ''Kamen Rider Den-O: Ore, Tanjo!'' (2007): TheMovie (the first of many) for ''Den-O''. Set after episode 27 and serving as the climax to a story arc that began in episode 25, with the beginning of episode 28 being the denoument.
70** ''Saraba Kamen Rider Den-O: Final Countdown'' (2008): The third ''Den-O'' movie after ''Climax Deka'' (see below), introducing Den-O’s [[KidFromTheFuture Grandkid from the Future]] New Den-O, who will serve as the representative for this series in later crossovers in place of Ryotaro Nogami due to the actor’s StarMakingRole catapulting him far beyond Toei’s paygrade.
71** ''Chō Kamen Rider Den-O & Decade Neo Generations: The Onigashima Warship'' (2009): The first installment in the ''Chō Den-O'' sub-franchise, taking place directly after episode 15 of ''Decade''.
72** ''Kamen Rider × Kamen Rider × Kamen Rider The Movie: Chō Den-O Trilogy'' (2010): A trilogy of DayInTheLimelight movies in the ''Chō Den-O'' sub-franchise, the first two of which focus on ''Den-O'' characters. The only actual narrative throughline connecting them is the first two films setting up a gag that pays off at the end of the third one.
73*** ''Episode Red: '''Zero no S'''tar Twinkle'' focuses on Yuto Sakurai aka Kamen Rider Zeronos, the Secondary Rider of ''Den-O''.
74*** ''Episode Blue: The Dispatched Imagin Is '''NEW'''tral'' centers on Kōtarō Nogami aka Kamen Rider New Den-O and Teddy from the ''Final Countdown'' movie.
75** ''Kamen Rider Den-O: Pretty Den-O is Here!'' (2020): A ''Den-O'' movie starring a little girl taking up the mantle of Pretty Den-O. Includes some BreakingTheFourthWall references to monsters from the original series and ''Zero-One'', and visits the time period of ''BLACK RX'', with RX himself getting a brief gag cameo after the credits.
76** The ''Deneb Kanjinchō'' (2020) novel focusing on Deneb and Zeronos features elements of ''Zi-O'' and takes place after its tribute episodes.
77* ''Series/KamenRiderKiva'' (2008-09)
78** ''Kiva'' and ''Den-O'' ostensibly cross over in ''Climax Deka'' (2008), though [[SpotlightStealingCrossover in practice]] it is a ''Den-O'' movie that the ''Kiva'' characters show up in.
79** ''Kamen Rider Kiva: King of the Castle in the Demon World'' (2008): NonSerialMovie for ''Kiva''.
80* ''Series/KamenRiderDecade'' (2009): This series introduces TheMultiverse, with alternate universe counterparts of each of the first nine Heisei Rider series and the prospect of a MergedReality between them being endangered WhenDimensionsCollide. From this point onwards, most Rider series, from the original to the present, are said to take place in the same world, with an annual crossover movie between the current series and the previous one.
81** The ''Den-O'' tribute episodes serve as the basis for the ''Chō Den-O'' sub-franchise, and notably take steps to imply that the World of Den-O visited by Decade is the original setting of the ''Den-O'' TV series, handwaving the differences with a TimeyWimeyBall instead of chalking it up to an alternate universe like the other A.R. Worlds visited.
82** Episodes 24 & 25 cross over with ''Samurai Sentai Shinkenger'', tying into Acts 20-22 of the latter and treating the World of Shinkenger as a universe without Kamen Riders where the presence of a ''Shinkenger'' MonsterOfTheWeek turning into a Rider is an anomaly.
83** Episodes 26 & 27 are tributes to ''BLACK'' and ''BLACK RX'', featuring the two versions of Kotaro Minami teaming up. Later crossovers will continue to depict the two as separate Riders despite both being Kotaro, implicitly treating one or both of them as hailing from one of the worlds in these episodes but generally not bothering to explain it. The episodes also introduce Dai-Shocker as the main antagonists, a new iteration of Shocker from the original series and expanding the anniversary celebration beyond the Heisei era.
84** ''Film/KamenRiderDecadeAllRidersVsDaiShocker'' (2009): TheMovie for ''Decade'', taking place between the ''Amazon'' tribute episodes and the final two episodes of the series. Features an EarlyBirdCameo debut for Double from the next season.
85** ''Episode Yellow: Treasure '''DE End''' Pirates'' (2010): The finale to the ''Chō Den-O Trilogy'', focusing on Daiki Kaito/Kamen Rider Diend and delivering the punchline to the gag that was set up in the previous two ''Chō Den-O'' movies.
86* ''Film/KamenRiderG'' (2009) is an AffectionateParody short which features Decade (and the first nine Heisei Riders) dropping in on the eponymous hero via a dimensional wall.
87** The eponymous Rider fights against the organization Shade which, due to a reuse of costumes, has its ranks made up of modified humans who assume the form of Worms from ''Kabuto'', whilst G rides V3's Hurricane bike from ''Kamen Rider: The Next''.
88** A Neo-Shade appears in ''Series/KamenRiderDrive''.
89** G later cameos in TheMovie for ''Kamen Rider Zi-O'' alongside other "Lost Heisei Riders".
90** As in the real world, ''Super Sentai'' exists as a TV Asahi production in this reality as evidenced by the appearance of a poster for ''Gekiranger vs. Go-Onger''.
91[[/folder]]
92
93[[folder:Heisei Era Phase 2]]
94* ''Series/KamenRiderDouble'' (2009-10): This series introduces Foundation X, an evil organization which resurfaces to haunt later shows. Provides a SequelHook to ''OOO'' with Foundation X mentioning the Core Medal in its antepenultimate episode.
95** Starts the tradition of the new Rider making an EarlyBirdCameo in TheMovie, first with Double himself debuting in Decade’s movie, then with the appearance of OOO in Double’s movie ''Film/KamenRiderWForeverAToZTheGaiaMemoriesOfFate'' (2010), which fits between episodes [[Recap/KamenRiderDoubleE43E44TheOChain 44]] & [[Recap/KamenRiderDoubleE45E46WhatKNeeds 45]].
96** Crossed over with ''Decade'' in ''Film/KamenRiderxKamenRiderWDecadeMovieWar2010'' ([[NonIndicativeTitle released and set in 2009]]), which was the FullyAbsorbedFinale to ''Decade''’s story and is set between episodes [[Recap/KamenRiderDoubleE11E12TheVengefulV 12]] & [[Recap/KamenRiderDoubleE13E14TheRadioQ 13]] of ''Double''.
97** ''Kamen Rider Double: Donburi’s α/Farewell, Beloved Recipe'' (2010) is the first ''Magazine/TeleviKun'' Hyper Battle DVD pitting Double against the Oyakodon Dopant threatening the Fumen cart, the proprietor of which becomes a recurring character in side content relating to ''Double''. AllThereInTheManual sets it after [[Recap/KamenRiderDoubleE35E36BeyondR episode 35]].
98** ''Kamen Rider Double DVD: Gaia Memory Encyclopedia'' (2010) is the second ''Televi-Kun'' special, an immediate sequel to the first one in which Shotaro reviews the Gaia Memories in their arsenal to an amnesiac Philip. The cause of the EasyAmnesia turns out to have been Philip slipping on an overly hardboiled egg Shotaro tossed aside during the cooking contest in the previous special.
99** ''Kamen Rider W Returns'' (2011) Post-series V-Cinema releases.
100*** ''Kamen Rider Accel'' focuses on Ryu Terui and takes place after his wedding with Akiko depicted in ''Movie War Core''.
101*** ''Kamen Rider Eternal'' acts as a prequel to ''Gaia Memories of Fate'' that depicts the StartOfDarkness for that film’s BigBad Katsumi Daido.
102** ''Kamen Rider Double: ~The One Who Continues After Z~'' (2012): A TieInNovel set between episodes [[Recap/KamenRiderDoubleE31E32TheBCarriedOnTheWind 32]] & [[Recap/KamenRiderDoubleE33E34YsTragedy 33]], featuring Philip’s solo transformation into Kamen Rider Cyclone with a Lost Driver that he will later bequeath to Shotaro to become Kamen Rider Joker in the finale and subsequent appearances.
103** ''Manga/FuutoPI'' (2017-present): A manga SequelSeries [[SequelInAnotherMedium in Another Medium]] to ''Double''.
104* ''Series/KamenRiderOOO'' (2010-11): Episodes 27 & 28 celebrate the 999th and 1000th episodes of the whole franchise by BreakingTheFourthWall to have the cast film their own movie adaptation of the original series, with Kougami binging all the previous shows (including the nonexistent ''Riderman'' and ''ZX'' seasons) and a [[{{Mook}} Shocker Combatman]] as the VictimOfTheWeek hosting the episodes’ Yummy to recreate footsoldiers from prior seasons. Provides a SequelHook to ''Fourze'' by having two supporting characters make TheCameo in the final episode.
105** Crossed over with ''Double'' in ''Kamen Rider × Kamen Rider OOO & W Featuring Skull: Movie War Core'' (2010). While there are numerous continuity problems that prevent it from fitting neatly with ''OOO'' (though it is definitely canon to ''Double''), the ''OOO'' TieInNovel (2012) set after the events of ''Movie War [=MegaMax=]'' does attempt to explain at least one of those contradictions, and ''Movie War Core''’s best placement ignoring the continuity errors would be after the debut of the [=SaGouZo=] Combo in episode 12.
106** ''Film/OOODenOAllRidersLetsGoKamenRiders'' (2011) celebrates the 40th anniversary of the whole franchise with the ''OOO'' cast getting involved in time travel shenanigans courtesy of ''Den-O'' that result in an alternate timeline where Shocker rules the world. Continuity issues keep it from fitting into the narrative of ''OOO'' perfectly (and the ''OOZ'' story of ''Literature/SICHeroSaga'' handwaves the movie’s events as AllJustADream), but the best fit for it would be after episode 28.
107** The summer movie ''Film/KamenRiderOOOWonderfulTheShogunAndThe21CoreMedals'' (2011) hosts the debut of Fourze himself. It also acts as a crossover with ''Series/AbarenboShogun'', using a CelebrityParadox and time travel to imply it is simultaneously a ShowWithinAShow to ''OOO'' and set in the same universe. Once again, there are continuity issues keeping it from fitting perfectly into the narrative of the show, but the calendar date and BroadStrokes best place it circa episode 36.
108** ''Film/KamenRiderOOO10thCoreMedalOfResurrection'' (2021): A ReunionShow movie to celebrate the 10th anniversary of ''OOO'', though it seemingly ignores and contradicts all of OOO’s appearances in movies after the end of his own series.
109* ''Series/KamenRiderFourze'' (2011-12): The second episode has Tomoko Nozawa introduce Fourze to the concept of a Kamen Rider by showing him battle footage of Rider #1 from the original series, Super-1, and Kuuga, and an article about the destruction of Fuuto Tower from ''Double''’s movie. Provides a SequelHook to ''Wizard'' by having him make TheCameo out of his suit in the finale.
110** Crossed over with ''OOO'', ''Double'', and the original Seven Legendary Riders in ''Film/KamenRiderXKamenRiderFourzeAndOOOMovieWarMegaMax'' (2011) to fight against Foundation X. Set between episodes 14 & 15.
111** ''Kamen Rider Fourze Hyper Battle DVD: Rocket Drill States of Friendship'' (2012) is the first ''Magazine/TeleviKun'' Hyper Battle DVD for Fourze, teaming up with Kamen Rider Amazon to fight a PaletteSwap of the Suddendath monster from ''[=MegaMax=]''. The events of the special are referenced in ''Movie War Ultimatum''.
112*** ''Kamen Rider Fourze Special Bonus DVD: Astroswitch Secret Report'' (2012) is the second ''Televi-Kun'' special and a prequel to the first one, reviewing the 40 Astroswitches obtained to determine the location of the Clear Drill Switch that appears in ''Rocket Drill States of Friendship''. Can be set after episode 32, the conclusion of the arc introducing the Cosmic Switch and formally bringing Meteor into the Kamen Rider Club.
113** The summer movie ''Film/KamenRiderFourzeTheMovieEveryoneSpaceIsHere'' (2012) hosts the debut of Wizard as a Rider. AlternateContinuity versions of the heroes from ''Series/SpaceIronmenKyodain'' serve as the main antagonists. Scenes from the director’s cut version clarify its position in the narrative as being set between episodes 38 & 39.
114** ''Kamen Rider Fourze: ~Ama High Graduation~'' (2014) is a TieInNovel taking place after the finale, featuring the return of Nadeshiko and the S.O.L.U. from ''Movie War [=MegaMax=]'' and set before the five-year TimeSkip to the ''Fourze'' act of ''Movie War Ultimatum'', with Fourze’s appearance in ''Heisei Generations FINAL'' retconned to take place between the novel and ''Ultimatum''.
115* ''Series/KamenRiderWizard'' (2012-13): Closes with a TwoPartEpisode in which Wizard ([[TheSixthRanger and Beast]]) are transported to an AlternateUniverse along with the first thirteen Heisei Rider protagonists and the new guy, Gaim, using the Kamen Rider Rings introduced in ''Movie War Ultimatum''.
116** Crossed over with ''Fourze'', ''OOO'', and ''Double'' in ''Film/KamenRiderXKamenRiderWizardAndFourzeMovieWarUltimatum'' (2012), which brought along Double, OOO, and their Secondary Riders via the use of Kamen Rider Rings. The first act of the movie dedicated to ''Fourze'' is set five years after the end of the season, but concludes with them time traveling to Wizard’s present day. AlternateContinuity versions of the protagonists from ''Series/Akumaizer3'' and ''Series/BishoujoKamenPoitrine'' feature as well. Set before episode 14.
117** ''Film/KamenRiderWizardInMagicLand'' (2013): TheMovie for Wizard, set in an AlternateUniverse created by the BigBad Kamen Rider Sorcerer and fixed by the end of the movie. While its position in relation to ''Wizard''’s narrative is not concrete, one could reasonably set it after the debut of the TV series versions of Kamen Rider Mage (episode 40) and before the cracks in Koyomi’s hand appear (episode 45) that persist to the end of the series.
118** ''The Sorcerer’s Apprentice'' (2014) is the ''Literature/SICHeroSaga'' edition for ''Wizard'', crossing over with ''OOO'' and set after the novel.
119** The ''Wizard'' TieInNovel released in 2014 takes place between Wizard’s part in ''The Fateful Sengoku Movie Battle'' and ''The Sorcerer’s Apprentice'', pitting Haruto against his EnemyWithout Black Wizard.
120* ''Series/KamenRiderGaim'' (2013-14): Promoted the ''Film/KikaiderREBOOT'' movie with a crossover in episode 30 (which chronologically takes place during episode 26).
121** Crossed over with ''Wizard'' in ''Film/KamenRiderXKamenRiderGaimAndWizardTheFatefulSengokuMovieBattle'' (2013), which was a FullyAbsorbedFinale to ''Wizard'' and featured an alternate universe of Bujin Rider counterparts to the first fifteen leading Heisei Riders, and which introduces the Legend Rider Lockseeds and Rider Arms forms that appear in later crossovers. Set between episodes 9 & 10, with ''Gaim Gaiden: Duke'' taking place before it.
122** ''Recap/KamenRiderGaimHyperBattleDVDFreshOrangeArmsIsBorn'' (2014): The Hyper Battle DVD special, presumably set before the debut of the Genesis Riders in episode 12.
123** Began the tradition of ''Rider'' and ''Sentai'' having crossovers to promote the new spring movie, by having a crossover with ''Ressha Sentai [=ToQger=]'' in ''Recap/ResshaSentaiTokkyugerVsKamenRiderGaim Spring Vacation Combining Special'', which features a surprise cameo by Narutaki from ''Decade'' to promote ''Kamen Rider Taisen''. The Double Riders and [=V3=] also cameo near the end. Set after Gaim acquires [[MidSeasonUpgrade Kachidoki Arms]] in episode 23.

219! ''Film/SpaceSquad''
220From 2012 onwards, ''Super Sentai'' and ''Metal Heroes'' are consistently treated as taking place in the same universe.
221!! ''Franchise/SuperSentai''
222Generally, individual Sentai have their own mythos and are independent continuity-wise, with {{crossover}}s taking place in TheMovie or other specials. However, televised crossovers have become more common in later years, especially after ''Gokaiger''. Thus, the majority of Super Sentai are presumed to take place in the same universe. There is conflicting evidence both for and against ''Super Sentai'' sharing a universe with ''Kamen Rider''.

224* ''Series/JAKQDengekitai'' (1977): The first two Sentai team up in ''Film/JAKQDengekitaiVsGoranger'', which is the GrandFinale to ''J.A.K.Q.'' set after its last episode. There are mentions of the heroes of ''Kamen Rider V3'', ''Kamen Rider Amazon'', and ''Kikaider'' in said movie.
225* ''Series/BattleFeverJ'' (1979-1980): According to the Marvel Master List, this series (and by extension the other ''Super Sentai'') takes place in the defunct Earth-79203 of the Franchise/MarvelUniverse’s multiverse, due to it, ''Denziman'', and ''Sun Vulcan'' having each been an InternationalCoproduction with Creator/MarvelComics.
226* ''Series/DenshiSentaiDenziman'' (1980-1981)
227* ''Series/TaiyouSentaiSunVulcan'' (1981-1982): Uniquely, ''Sun Vulcan'' follows on from ''Denziman'', reprising Queen Hedrian, the Vader Clan, and the people of Planet Denzi, with Denziman themselves referred to by name.

228* ''Series/DaiSentaiGoggleFive'' (1982-1983)
229* ''Series/KagakuSentaiDynaman'' (1983-1984): A statue of ''Robocon'', implicitly a fictional character in-universe, can be seen in one episode in what is more likely a consequence of filming at an amusement park rather than a deliberate reference.

233* ''Series/HikariSentaiMaskman'' (1987-1988): #38 shows Takeru (Red Mask) as a child imitating ''Kikaider'', implying the latter is a fictional hero in this reality.
234* ''Series/ChoujuuSentaiLiveman'' (1988-1989)
235* ''Series/KousokuSentaiTurboranger'' (1989-1990): ''Turboranger'' is opened by a special RecapEpisode where the Turborangers meet the ten previous Super Sentai from ''Battle Fever'' to ''Liveman''[[note]]At the time, ''Turboranger'' was considered the eleventh installment of the franchise and ''Battle Fever J'' the first, the two Ishinomori-helmed seasons not being counted yet[[/note]].
236** The Turborangers’ high school Musashino Academy makes a handful of cameos in later series, sponsoring the Zyuman Circus in TheMovie for ''Zyuohger'', being the alma mater of the SixthRanger of ''Kiramager'', and appearing in Don 14 of ''Donbrothers''.
237* ''Series/ChikyuuSentaiFiveman'' (1990-1991): #43 hints that the previous Sentai are but television shows when clips from ''Denziman'' and ''Battle Fever J'' are seen on a TV, but it’s complicated since an earlier episode of ''Fiveman'' appears as well.

239* ''Series/KyoryuSentaiZyuranger'' (1992-1993)

249* ''Series/NinpuuSentaiHurricaneger'' (2002-2003): Crossed over with ''Gaoranger'' in ''Hurricaneger vs. Gaoranger''.

252** The Dino House curry restaurant used as the team’s HomeBase is referenced in several later crossover movies as a place where supporting characters from the featured seasons have met and befriended each other.
253** The 20th anniversary reunion movie appears to be set primarily in the continuity of the television series and contradicts the ''Abaranger'' characters’ appearances in most other crossovers (most prominently the Dino House running gag), but was promoted by a special crossing over with ''Donbrothers''.
254** Episode 26 is the second part of a crossover with the anime adaptation of ''Manga/TsuribakaNisshi'', continuing from episode 31 of the latter, but treating it as a ShowWithinAShow.
255* ''Series/TokusouSentaiDekaranger'' (2004-2005): Crossed over with ''Abaranger'' in ''Dekaranger vs. Abaranger''.
256** The 10th anniversary reunion movie is set primarily in the continuity of the television series and does not mention any of the Dekarangers’ appearances in other crossovers, but does not contradict those appearances either.
257** The ''Fireball Booster'' movie celebrates the 20th anniversary of the season, and is promoted by a web special ''Dekaranger with Tombo Ohger'' teaming up the Blue Ranger of ''King-Ohger'' with [=DekaYellow=][[note]]who happens to be his actor’s childhood celebrity crush growing up[[/note]] and [=DekaPink=].

259* ''Series/GoGoSentaiBoukenger'' (2006-2007): Crossed over with the first 29 Super Sentai in ''Boukenger vs. Super Sentai'', which introduces [=AkaRed=], a character that appears in subsequent anniversaries, acting as the leader of a Sentai dream team with members from ''Magiranger'', ''Dekaranger'', ''Abaranger'', and ''Hurricaneger''.
260* ''Series/JukenSentaiGekiranger'' (2007-2008): Crossed over with ''Boukenger'' in ''Gekiranger vs. Boukenger''.
261* ''Series/EngineSentaiGoOnger'' (2008-2009): Crossed over with ''Gekiranger'' in ''Go-Onger vs. Gekiranger''.
262** The ''10 YEARS GRANDPRIX'' movie implicitly acknowledges other crossovers by mentioning Speedor & [=BearRV=]’s marriage established in the ''Gokaiger'' tribute episodes and a BrickJoke from ''Shinkenger vs. Go-Onger''.
263* ''Series/SamuraiSentaiShinkenger'' (2009-2010): Was one of the worlds of TheMultiverse visited in ''Kamen Rider Decade'', which treated the World of Shinkenger as one without Riders and the introduction of a Rider as an anomaly.
264** Crossed over with ''Go-Onger'' in ''Shinkenger vs. Go-Onger'', which also starts a new tradition of EarlyBirdCameo by introducing the team from ''Goseiger''. The [[GoldfishPoopGang Gaiark trio]] stealing [[SixthRanger Genta]]’s sushi cart and a bottle of booze from it in this movie will be a BrickJoke during their appearances in future movies.
265* ''Series/TensouSentaiGoseiger'' (2010-2011): Crossed over with ''Shinkenger'' in ''Goseiger vs. Shinkenger'', which also introduces the team from ''Gokaiger'' in an EarlyBirdCameo that initially seems to be a ContinuitySnarl with ''Gokaiger''’s premise until the ''Timeranger'' tribute episode retroactively explains it.
266* ''Series/KaizokuSentaiGokaiger'' (2011-2012): The 35th anniversary series, ''Gokaiger''’s setting is a world where the first 34 Super Sentai all exist, with the Gokaigers inheriting their powers and {{Continuity Cameo}}s galore in various tribute episodes.
267** Crossed over with ''Goseiger'' directly in ''199 Heroes'', which was a tribute episode to ''Goranger'' and featured additional returning legends and villains from ''J.A.K.Q.'', ''Denziman'', ''Goggle-V'', ''Dynaman'', ''Bioman'', ''Turboranger'', ''Dairanger'', ''Carranger'', ''Gingaman'', ''Dekaranger'', ''Magiranger'', ''Boukenger'', ''Go-Onger'', and ''Shinkenger''.
268** Episodes 25 & 26 were a direct crossover with ''Hurricaneger'', having the Hurricaneger trio temporarily regain their powers to fight alongside the Gokaigers.
269** In addition to being a ''Timeranger'' tribute, Episode 40 uses time travel to explain the Gokaigers’ EarlyBirdCameo in ''Goseiger vs. Shinkenger'', as well as sets up the events of the RecapEpisode and ''Kakuranger'' tribute episode.
270** Started the trend of ''Metal Hero'' crossovers by doing so with ''Gavan'' (the first Metal Hero) in ''Gokaiger vs. Gavan'', which also introduces the team from ''Go-Busters''. Kenji Ohba’s previous roles in ''Battle Fever J'' and ''Denziman'' appear alongside Gavan, as do retired villains from ''Abaranger'', ''Magiranger'', ''Boukenger'', ''Gekiranger'', and ''Go-Onger'' (the last of which are the Gaiark trio continuing the BrickJoke from their last appearance).
271* ''Series/TokumeiSentaiGobusters'' (2012-2013): A FreezeFrameBonus in the first episode mentions the Asami Group from ''Timeranger''. Guest stars the hero from ''Film/SpaceSheriffGavanTheMovie'' in a TwoPartEpisode.
272** The original Gavan also cameos in the Hyper Battle DVD.
273** Crossed over with ''Gokaiger'' in ''Go-Busters vs. Gokaiger'', which also introduces the team from ''Kyoryuger'' and features a returning appearance from Kaoru Shiba of ''Shinkenger''.
274* ''Series/HikoninSentaiAkibaranger'' (2012-2013): Broadcast over two seasons, ''Akibaranger'' is an "unofficial" Sentai spin-off which takes place in a world where ''Super Sentai'' is but a fictional television franchise, but is distinct from the real world in that the ''Space Sheriff'' franchise is an anime franchise named ''Galactic Sheriff'' amongst other differences. The ''Akibaranger'' world itself is in its own little multiverse alongside the Delusion World where the Akibarangers fight their battles, the world of Saburo Hatte (the writer).
275** A LeaningOnTheFourthWall reference in ''[[Film/SpaceSheriffGavanVsTokusouSentaiDekaranger Gavan vs. Dekaranger]]'' could suggest that ''Akibaranger'' has influence on the prime ''Super Sentai'' universe itself.
276** The Akibarangers’ influence on the prime universe is further implied in ''Superhero Senki'' via the Zenkaigers using an Akibaranger Sentai Gear, indicating that ''Akibaranger'' is a world within the ''Zenkaiger'' multiverse.
277* ''Series/ZyudenSentaiKyoryuger'' (2013-2014): Crossed over with ''Go-Busters'' (plus ''Zyuranger'' and ''Abaranger'') in ''Kyoryuger vs. Go-Busters'', which also introduces the team from ''[=ToQger=]''.

279** ''Series/PowerRangersDinoForceBrave'' (2017): A Korean SequelSeries to ''Kyoryuger'', translated into Japanese as ''Zyuden Sentai Kyoryuger Brave''. Features TheCameo by the team from ''Zyuohger'' in the finale. The connection is furthered by a ContinuityCameo in ''Chou Super Hero Taisen''.
280* ''Series/ResshaSentaiToQger'' (2014-2015): There are small references to ''Go-Busters'' and ''Gekiranger'' in a few episodes.
281** Crossed over with ''Kamen Rider Gaim'' to promote the ''Kamen Rider Taisen'' movie.
282** Crossed over with ''Kyoryuger'' in ''[=ToQger=] vs. Kyoryuger'', which also introduces the team from ''Ninninger''.
283* ''Series/ShurikenSentaiNinninger'' (2015-2016): Uniquely, ''Ninninger'' hosted several guest appearances from legendary heroes in its televised run (including characters from ''Kakuranger'', ''Hurricaneger'', ''Goranger'', ''Magiranger'', and even ''Series/SekaiNinjaSenJiraiya'').
284** The crossover with ''Kamen Rider Drive'' to promote ''Super Hero Taisen GP'' notably treats ''Ninninger'' as taking place in a separate universe from ''Drive'', requiring dimensional travel for the casts to interact and treating the Ninningers’ presence outside their own universe as something hazardous to them.
285** Crossed over with ''[=ToQger=]'' in ''Ninninger vs. [=ToQger=]'', which also introduces the team from ''Zyuohger''.
286* ''Series/DoubutsuSentaiZyuohger'' (2016-2017): Crossed over with ''Kamen Rider Ghost'' to promote the ''Kamen Rider 1'' movie. Guest stars the team from ''Gokaiger'' in a TwoPartEpisode to celebrate the 1999th and 2000th episodes of the franchise, including new Ranger Keys from the seasons between them and cloning villains from ''Shinkenger'', ''Goseiger'', ''Go-Busters'', ''Kyoryuger'', and ''[=ToQger=]''.
287** The ''Super Animal War'' miniseries features [=AkaRed=] returning with another dream team of veteran Sentai Rangers, this time from ''Ninninger'', ''[=ToQger=]'', ''Kyoryuger'', and ''Go-Busters'', plus a reformed MonsterOfTheWeek from ''Gokaiger''. However, the entire miniseries takes place out of continuity with ''Zyuohger'' and has NoFourthWall.
288** Crossed over with ''Ninninger'' (plus TheCameo from the first 38 Super Sentai) in ''Zyuohger vs. Ninninger'', which also introduces the team from ''Kyuranger''.
289* ''Series/UchuSentaiKyuranger'' (2017-2018): Uniquely, ''Kyuranger'' sets itself in an AlternateUniverse to the prime ''Super Sentai''/''Space Squad'' reality, as seen when the team crosses dimensions and meets the Dekarangers and Space Sheriffs in episode 18, which is recalled in #27 (the RecapEpisode). There is also a cameo by Kamen Rider Ex-Aid in an episode to promote ''Chou Super Hero Taisen'', which has him summoned from his native universe.
290** Crossed over with ''Space Squad'' directly in ''Kyuranger vs. Space Squad'', which has Demost from ''Jiraiya'' revive Basco from Escape from ''Go-Busters'', Basco from ''Gokaiger'', Juzo from ''Shinkenger'', and Mele from ''Gekiranger'' to serve him.
291* ''Series/KaitouSentaiLupinrangerVsKeisatsuSentaiPatranger'' (2018-2019): The finale shows Shiho Ichinose creating an in-universe manga ''Good Three'' based on the Lupinrangers that becomes a ShowWithinAShow read by other characters from later seasons, such as ''Kiramager''.
292** Crossed over with ''Kyuranger'' (and a cameo from the SixthRanger of ''Zyuohger'' to [[BreakingTheFourthWall complain about his season]] not getting a proper crossover with the next) in ''Lupinranger VS Patranger VS Kyuranger'', which involves dimensional travel consistent with ''Kyuranger''’s AlternateUniverse status.
293* ''Series/FourWeekContinuousSuperSentaiStrongestBattle'' (2019): A mini-series which unites the majority of the first 42 Super Sentai while introducing the 43rd.
294* ''Series/KishiryuSentaiRyusoulger'' (2019-2020): Crossed over with ''Lupinranger VS Patranger'' in ''Ryusoulger VS Lupinranger VS Patranger''.
295* ''Series/MashinSentaiKiramager'' (2020-2021): Had a one-episode crossover with supporting characters from ''Gekiranger'', building on the established connection between SCRTC from said season and Sena Hayami.
296** Crossed over with ''Ryusoulger'' in ''Kiramager vs. Ryusoulger''.
297* ''Series/KikaiSentaiZenkaiger'' (2021-2022): Like ''Kamen Rider Decade'', ''Zenkaiger'' uses the concept of TheMultiverse. Like ''Kamen Rider Zi-O'', ''Zenkaiger'' treats all previous seasons as taking place in their own individual worlds, though the extent to which they are separate is currently unclear, though ''Gokaiger'' is seemingly treated as one CrossoverAlternateUniverse for the first 35 seasons, [[spoiler:and a FreezeFrameBonus during the season’s endgame implies the existence of another CrossoverAlternateUniverse called Super Sentaitopia that may be the setting of every prior season sans ''Kyuranger'']]. Introduces the Red Ranger of the next season ''Donbrothers'' in episode 42.
298** Also crossed over with ''Kamen Rider Saber'' to promote ''Superhero Senki''.
299** Crossed over with ''Kiramager'' in ''Zenkaiger vs. Kiramager vs. Senpaiger'', with the Senpaiger team consisting of Red Rangers from ''Gokaiger'' to ''Ryusoulger''.

Zenkaizer of ''Series/KikaiSentaiZenkaiger'' and ''Series/KamenRiderSaber'' make a cameo in the ending theme of the third episode. It is not known if it takes place in the same universe as ''Series/HikoninSentaiAkibaranger'' or is its own universe.
302* ''Series/AvataroSentaiDonbrothers'' (2022-2023): For the first time since the transition from ''Denziman'' to ''Sun Vulcan'', ''Donbothers'' is a SequelSeries to its immediate predecessor ''Zenkaiger'', with the Donbrothers’ Avataro Gears being functionally successors to the Zenkaigers’ Sentai Gears, and the Red Ranger [=DonMomotaro=] making his debut in episode 42 of ''Zenkaiger''. An AlternateSelf of ''Zenkaiger''’s lead hero Kaito Goshikida appears as the Donbrothers’ MissionControl, and is able to transform into Zenkaizer Black, a PaletteSwap of the original Zenkaizer.
303** Crossed over with ''Zenkaiger'' directly in ''Donbrothers vs. Zenkaiger''. Also had a web special team up with the Senpaigers to promote the aforementioned ''Zenkaiger vs. Kiramager vs. Senpaiger'' movie.

305* ''Series/OhsamaSentaiKingOhger'' (2023-2024): The main mecha, King-Ohger, makes its debut in episode 45 of ''Donbrothers''. ''King-Ohger'' takes place in its own mirror version of Earth called Tikyū as the setting and the team being monarchs from the planet’s kingdoms.
306** #31-32 is a two-part crossover with ''Kyoryuger'' which confirms that, unlike ''Kyuranger'', ''King-Ohger'' is still set within the prime ''Super Sentai'' universe, just on a different planet, the natives of Tikyū being descended from Earthlings.
307** Crossed over with ''Donbrothers'' in ''King-Ohger vs. Donbrothers'' and with ''Kyoryuger'' again in ''King-Ohger vs. Kyoryuger''.
308** The Blue Ranger of the team, Tombo Ohger, crossed over with ''Dekaranger'' in the ''Dekaranger with Tombo Ohger'' web special, which promotes the ''Dekaranger'' 20th anniversary movie and takes place prior to the TimeSkip in ''King-Ohger''.
309* ''Series/BakuageSentaiBoonboomger'' (2024-): [[Recap/BakuageSentaiBoonboomgerEp12TheBakuageEngine Bakuage 12]] is a crossover teaming up with Go-On Red & Speedor from ''Go-Onger''.
