History Film / HeiseiRiderVsShowaRiderKamenRiderWarsFeaturingSuperSentai

* PowerCreepPowerSeep: One of the biggest fears about the movie is that the Heisei Riders, with their multiple forms and {{Super Mode}}s, would make their fight with the Showa Riders a CurbStompBattle. While some fights are easily one-sided (Kabuto takes out Stronger with just a Rider Kick and Fourze uses Rocket States to defeat Skyrider), the Showa Riders are no slouches as X easily defeats Faiz (To be fair Takumi was holding back for the majority of the fight) and Riderman easily grapple-hooks and slams OOO out of a Tatoba Kick.
** Also, it becomes clear that lack of special effects doesn't mean lack of strength, and now that they ''do'' have the effects to make it look like what modern fans are used to seeing, you'll find watching the old Riders use the same powers they always had don't even ''look'' weak. Of course, we've seen such before (''All Riders vs. Dai Shocker'''s Rider tournament and the Seven Legendary Riders vs. Foundation X's cloned monsters in ''Movie Wars Megamax.'') ''All'' transformations, Stronger's electric powers, Skyrider's various special attacks and X-Rider's [[SigilSpam energy X-es that were once just the letter on a black background]] ''really'' lend themselves to the BigBudgetBeefUp treatment.

* AdaptedOut: No mention is ever made of Phillip, who should be crucial to the appearance of Series/KamenRiderDouble, leaving Shotaro to fight as Joker before returning as Double in the final battle ([[spoiler:perhaps Phillip was in on Murasame's plan and was waiting for Shotaro in the Helheim Forest]]). There's also zero mention of [[spoiler:Takumi being an Orphenoch.]]

** Kusaka's death is entirely different from how it actually played out in Faiz, to the point that the "Flashback" is completely new footage. Though it's possible this is some kind of AU take on it.

* FakeShemp: With such a heavy emphasis on a grand total of 30 main Riders, this is unfortunately going to be a thing. Sadly, this happened by default to [[Series/KamenRiderV3 Riderman]] and [[Series/KamenRiderStronger Stronger]] due to the [[DiedDuringProduction passing of their actors]]. Ultimately averted for nine Riders (Ichigou, X, ZX, Faiz, Den-O, Decade, Double/Joker, Wizard and Gaim).

* {{Retcon}}: [[spoiler:In ''Series/KamenRiderFaiz'', Kusaka died by having his neck snapped with no one noticing. In the movie, it's changed so that Kusaka dies in Takumi's arms, setting off his HeroicBSOD.]] Also, Kiba fights alongside the Orphenoch King, where in the series, [[spoiler: he did kill Kusaka, but ''Kusaka [[AssholeVictim had it coming]]''. It's Kiba who wears the Kaixa armor in the final battle ''against'' the Orphenoch King.]]

* ContinuitySnarl: Kouta, ''Armored'' Rider Gaim, does not recognize Hongo's use of the term "Kamen Rider" initially and needs a child to explain it to him despite learning what one is from Wizard in the last episode of his show, which implicitly took place during the first few episodes of ''Gaim''.

* ArmorPiercingSlap: X delivers one to Faiz after Kusaka's ghost pushes him to interfere with destroying the Mega-Reverse Machine.

* DefeatEqualsExplosion: Taken UpToEleven as this trope is played straight not just for all defeated villains ([[spoiler:Even the Generalissimo of Badan falls in the end.]]) but the Kamen Riders defeated during the Heisei vs. Showa war, the latter being a non-fatal example as the Riders are [[spoiler:being secretly transported to the Helheim Forest while leaving behind Lockseeds to be collected by Badan]].

** Tsukasa and Shotaro are obviously acquainted, having first met when the latter came to help the former in years back in ''[[Film/KamenRiderDecadeAllRidersVsDaiShocker All Riders vs. Dai-Shocker]]'' before fighting together in ''[[Film/KamenRiderXKamenRiderDoubleAndDecadeMovieWar2010 Movie War 2010]]''. Likewise, Fourze coming to help his 'buddy' Wizard against Fifteen is a subtle nod to ''[[Film/KamenRiderXKamenRiderWizardAndFourzeMovieWarUltimatum Movie War Ultimatum]]''.

* FakeShemp: With such a heavy emphasis on a grand total of 30 main Riders, this is unfortunately going to be a thing. Sadly, this happened by default to [[Series/KamenRiderV3 Riderman]] and [[Series/KamenRiderStronger Stronger]] due to the [[AuthorExistenceFailure passing of their actors]]. Ultimately averted for nine Riders (Ichigou, X, ZX, Faiz, Den-O, Decade, Double/Joker, Wizard and Gaim).

* TheCameo: Schwarz, one of ''Series/ResshaSentaiTokkyuger'''s bad guys, shows up briefly to offer the Badan Empire the Shadow Line's services to put Den-O out of commission.

* DavidVersusGoliath: Gabutyra vs. the Generalissimo of Badan, a good little T-Rex up against a big mean one. [=ToQ-Oh=] improves the odds somewhat but it takes the addition of the [=DenLiner=] and the resulting CombiningMecha to take down the Generalissimo.

* BadBoss: when the Generalissimo joins the final battle, he opens fire on the Riders, with little care for the mooks that were in the line of fire.

''Heisei Rider vs. Showa Rider: Kamen Rider Wars feat. Super Sentai'' is the third installment of the ''Super Hero Taisen'' movie franchise, following ''Film/KamenRiderXSuperSentaiSuperHeroTaisen'' and ''Film/KamenRiderXSuperSentaiXSpaceSheriffSuperHeroTaisenZ''. It is the first of these movies heavily leaning towards the Kamen Riders over Super Sentai, rather than focusing on them entirely. Toei allowed the fans to vote for whether Heisei or Showa won, much like the multiple endings of the ''13 Riders'' special for ''Ryuki''.

* CombiningMecha: [[spoiler:[=ToQ-Oh=] combines with both the Kyoryuger Ressha (transformed from [[Series/ZyudenSentaiKyoryuger Gabutyra]]) and [[Series/{{Kamen Rider Den-O}} Den-Liner]] to form [=ToQ-Oh=] Kyoryuzin feat. Den-Liner]].
