The {{crossover}} between ''Series/TokumeiSentaiGobusters'' and ''Series/KaizokuSentaiGokaiger''.

!!This movie contains examples of the following tropes:
* ActorAllusion: the Buster Hercules transforms into [[Series/MahouSentaiMagiranger MagiKing]], prompting Jin to comment that he feels right at home inside it.
** He even does the Magiranger hand pose!
* BackFromTheDead: Basco and Damaras, though technically they are Avatar replicas.
* CallForward: The other Kyoryugers arriving late to assist Kyoryu Red addresses the fact that, in the first few episodes, the team isn't open to one another.
* ContinuityCameo:
** [[Series/KaizokuSentaiGokaiger Jerashid]] appears once again, this time in the Edo period of Japan. And no, it's not a past version of him, as he's still wearing his wedding ring. Best not to question how and why he got there.
** Also stuck in the Edo period with no way to get back, Yoko, J, and Gai wonder how they can send a message to their allies in the present. J has the idea of [[WriteBackToTheFuture writing a message to them]], but Yoko asks the obvious question: Who could they trust to hold onto such a message for over 250 years? Gai then gets an idea. Cut to the present time, and [[Series/SamuraiSentaiShinkenger Shiba Kaoru]] personally delivers that very message to the Go-busters' HQ.
** Where does Marvelous go to eat? [[Series/BakuryuuSentaiAbaranger Dino Curry, being served by Yatsudenwani.]]
* ContinuityNod: The background music playing when Gokai-Oh [[spoiler:spawns the Megazord Keys, thus heralding the brief return of some past ''Super Sentai'' mechas,]] is the exact same one used in ''Film/GokaigerGoseigerSuperSentai199HeroGreatBattle'' when the 33 previous main mechas returned.
* EarlyBirdCameo: Like its predecessors, this movie marks the debut of the next Sentai team, ''Series/ZyudenSentaiKyoryuger'', where they take on Waredonaiyer and some Zangyack grunts. This is notable for being the first early-bird cameo to take place inside a warehouse, as the previous three all took place out in the open.
** It's also the first where a member of the cameo team meets with the two starring teams, as Kyoryu Red meets his two predecessors before his team's cameo proper start (the other members were late).
* [[spoiler: FakeDefector]]: Marvelous reveals to the Busters that their method was dealing with Zangyack from the inside through a pretend surrender, [[TheMole attacking their allies secretly]]. By the time the movie had started, they were already found out.
* LetsYouAndHimFight: The Go-Busters fight the Gokaigers, who have seemingly joined forces with the new Zangyack.
* MythologyGag: the whole point of the mechas transforming into other mecha.
** Gokai-Oh -> Daibouken: the Boukengers are the Gokaigers' predecessors as the anniversary team, and both series have an adventure theme.
*** Marvelous even imitates Akashi by snapping his fingers and saying [[GratuitousEnglish Attack]]!
** [=GoZyuJin=] -> [=DaiZyuZin=]: the Zyuranger Greater Power is one of the components of [=GoZyuJin=].
** Go-Buster Ace -> Gekitouja,Flash King and Ryuuseioh: All the Mechs are fast and agile. Gekitouja is composed of wild felines (even with a red one to boot), while Ryuuseioh is a red mech with his own robot form like Ace.
** Go-Buster Lioh -> [=GaoKing=] and Gao Kentaurus: Li-Oh and King have lion mechs as the central component of the combined mode plus Kentaurus was the final mech of the Gaorangers just like Li-Oh.
** Buster Hercules -> [=MagiKing=]: see ActorAllusion.
* PaletteSwap: Action Commander Waredonaiyer is basically a red version of Deratsueigar, the "[[MonsterOfTheWeek monster of the fortnight]]" in Gokaiger #11 and #12.
* {{Superdickery}}: [[spoiler:TheRemnant of Zangyack blackmailed the Gokaigers into this trope.]]
* TrappedInThePast: When Enter finds the last of the Phantom Ranger Keys, they react violently and open up a time portal, sending the Gokaigers, Yoko, J, and Gorisaki into the past with no way to get back.
* TheWorfEffect: Basco and Damaras are taken down rather quickly by the Gokaigers. Basco is defeated by Marvelous, Joe and Luka as [[Series/TaiyouSentaiSunVulcan Sun Vulcan]] while Damaras is defeated by Gai, Don and Ahim as [[Series/NinpuuSentaiHurricaneger Shurikenger and the Gouraigers]].
* WriteBackToTheFuture: By way of TheSlowPath.
