''Kaizoku Sentai Gokaiger vs. Space Sheriff Gavan: The Movie'' is a {{Crossover}} between ''Series/KaizokuSentaiGokaiger'' and ''Series/SpaceSheriffGavan''.

The legendary Space Sheriff Gavan is hired to capture the Kaizoku Sentai Gokaiger. However, Gavan himself is captured by Gavan Bootleg and is trapped in Makuu Prison, worst prison in the universe. The Gokaigers resolve to rescue the sheriff from the prison and join forces with him to fight Gavan Bootleg and Makuu Prison's warden, Asurada.

!!''Kaizoku Sentai Gokaiger vs. Space Sheriff Gavan: The Movie'' provides examples of the following tropes:

* TheAlcatraz: Part of the story takes place in Makuu Prison, a huge, highly guarded inter-dimensional prison complex which none have ever broken out from, with the Gokaigers even planning a breakout.
* AsideGlance: Upon defeating the Gokaigers, Gavan salutes at the camera.
* BehemothBattle: Kanzen [=GokaiOh=] and Dol vs. Asurada who enlarged himself.
* BorrowedCatchphrase: All the Gokaigers, including ''Machalcon'' in his BigDamnHeroes, borrow Marvelous' BattleCry, providing variations of their own (all except Gai, who can't come up with one).
* BookEnds: A shot of Gavan at the top of a flight of stairs, first when confronting Marvelous and then when he's doing his henshin pose.
* ChromeChampion: Gavan's suit has been redesigned to be a mostly bright chrome silver compared to it's original muted colors. (Not an upgrade, as it's supposed to be the same one he's always worn but they had to rebuild it since the old one had long been worn beyond use)
* CombinationAttack: Gokai Red and Gavan execute a finishing attack [[spoiler: on giant Asurada]] called the ''Gavan Marvelous Dynamic'' -- Marvelous plugs the Gokai Red Ranger Key into his Gokai Sabre for a Final Wave and does a powerful slash while Gavan uses his ''Gavan Dynamic'', a powerful slash from his LaserBlade.
* ContinuityCameo: Well there's obviously Gavan, along with Battle Kenya and Denzi Blue. Several past Super Sentai villains appear as well.
** [[Series/KaizokuSentaiGokaiger Action Commanders Sneak Brothers and Jerashid]]
** [[Series/BakuryuuSentaiAbaranger Trinoid 12 Yatsudenwani]]
** [[Series/MahouSentaiMagiranger Phantom Spy Vancuria]]
** [[Series/GoGoSentaiBoukenger Dark Shadow's Shizuka of the Wind and Gekkou of Illusions]].
** [[Series/EngineSentaiGoOnger The three main Gaiark Pollution Ministers]]. Yogostein is still drinking the sake stolen from Genta's sushi cart from ''Shinkenger vs. Go-Onger''!
** [[Series/TensouSentaiGoseiger Mons Drake, Kinggon and Robogog]].
** [[MyFriendsAndZoidberg ...and]] [[Series/JukenSentaiGekiranger Bae]].
* ContinuityNod:
** The Gokaiger mention to Gavan at the beginning of the movie that the Dekaranger have already cleared the Gokaigers' names with regards to the accusations by the Zangyack.
** Jerashid is wearing a wedding ring, consistent of when he last appeared in the series.
* CoolOldGuy: The trinity of Kenji Ohba.
* CrucifiedHeroShot: Gavan is held at the top of Makuu Prison, where his arms are spread out and restrained by cuffs on either end of the board he's cuffed to.
* DramaticDrop: Gai drops his groceries at the beginning, upon witnessing the aerial battle between the Gokai Galleon and Gavan's ship, and seeing his friends lose.
* DungeonBypass: How the Gokaigers quickly escape the Makuu prison: separated on different levels, they all shoot down at their feet, creating a hole on each floor to jump through.
* EarlyBirdCameo: This movie marks the first appearance of the Gokaiger's successors, ''Series/TokumeiSentaiGobusters'', who take on Basco.
* EvilKnockoff: Gavan Bootleg is an evil copy of the actual Gavan made by the Zangyack and the space police's technology.
* EvilTowerOfOminousness: Makuu Prison; Retsu is held at the very top of the structure.
* GracefulLoser: Surprisingly, Basco chooses to make his leave once he is thwarted by the Go-busters.
* HandshakeSubstitute: Marvelous and Retsu have a fist bump before the big brawl.
* {{Homage}}: The ending in which Gavan poses with Battle Kenya and Denzi Blue is a callback to the GrandFinale of ''Series/SpaceSheriffShaider'', in which the title character posed with Gavan and [[Series/SpaceSheriffSharivan Sharivan]].
* HeelFaceReturn: [[Series/GoGoSentaiBoukenger Dark Shadow]] were still antagonists (albeit, [[IneffectualSympatheticVillain rather lame ones]]) and here they’re in a jail for reformed villains. The implications are obvious.
* HopeSpot: The beginning of the movie has the Gokaigers believing they shot down Gavan's ship that was chasing them, until Electronic Starbeast Dol flies out of the flames and takes them down.
* InTheNameOfTheMoon: Gavan adds himself to the Gokaigers' roll call. Then there's the combined Kenji Ohba roll call of Battle Kenya, Denzi Blue and Gavan.
* IOweYouMyLife: Marvelous helps Gavan to return the favor, since Retsu saved a young Marvelous and helped make him the man he is today by teaching him to be brave. The other Gokaiger go along because, as they say, Marvelous' origin is their origin, so by association they owe him too.
* IntergenerationalFriendship: Marvelous and Retsu/Gavan.
* LetsYouAndHimFight: Gavan is hired by the Zangyack to capture the Gokaiger.
* LoverTugOfWar: Don between Shizuka and Kegalesia. Should he count as lucky or unlucky?
* ManVersusMachine: Gavan (Retsu, the human) versus Bootleg (the machine). As Retsu says in the final battle, Bootleg might know all his moves, but a mere machine can't copy the human soul.
* MirroredConfrontationShot: between Gokai Red and Gavan.
* NoodleIncident
** While discussing Gavan, Denzi Blue mentions to Battle Kenya that he met him once. An off-screen ''Denziman''/''Gavan'' teamup perhaps? This is more likely a LampshadeHanging of the aforementioned [[ActingForTwo Acting for Three]] trope.
** Jerashid is one of the inmates in the Makuu Prison. Since he had [[HeelFaceTurn retired from villainy]] earlier in the series, it's unclear what led to his imprisonment. He even starts to explain, but the Gokaigers blow him off.
* OhCrap: Basco briefly has this look after Red Buster introduces himself and then sees the other two Go-Busters standing to his left and right side.
* OutOfCharacterMoment: No actual reason is given to why Don decides to join Luka in beating up Gai, even if his rescue attempt was rather late.
* OverlyLongGag: The time Don takes to recover from a fall, in slow-motion.
* ProductionForeshadowing: In the [[Series/TokumeiSentaiGobusters Go-Busters]] EarlyBirdCameo, Basco assumes they are "Super Sentai wannabes", before they reveal themselves to be the 36th Super Sentai team. ''Series/HikoninSentaiAkibaranger'', an unofficial Super Sentai series which follows the adventures of an unofficial Sentai team trying to get their own TV show and be recognised as an official Super Sentai, first aired a few months after the movie was released.
* RememberTheNewGuy: Marvelous is revealed to have known Gavan some time in the past.
* ShotAtDawn: How the Gokaigers are supposed to be executed, complete with UnwillingSuspension.
* StealthPun: Gavan's Evil Counterpart is called Gavan Bootleg. Bootleg is another term for a [[FridgeBrilliance Pirated Copy.]]
* StrongAndSkilled: Gavan. He's a veteran hero of nearly 30 years but since he's a Space Sheriff and not a member of Super Sentai he didn't fight in the War and lose his power to transform in the aftermath. So unlike almost every other returning character he's still able to fight at full power and both defeats the Gokaigers all on his own and later solos Gavan Bootleg without any help from the team.
* ThemeSongPowerUp: The ''Space Sheriff Gavan'' and ''Kaizoku Sentai Gokaiger'' main themes play during the Gavan vs. Gavan Bootleg/Gokaigers vs. Asurada double battle near the end of the movie. Also, the Gokaigers and Gavan quote their own theme songs at various points during the movie to inspire or motivate themselves/others (such as Gavan's pep talk to a young Marvelous).
* TimeShiftedActor: Averted; Kenji Ohba plays Retsu in Marvelous's FlashBack, but they only ever show him from the back or in distant shots (and apparently touched up the gray out of his hair) in order to hide his age.
* TransformationSequence: According to the narrator, it takes one-twentieth of a second for Retsu to change into Gavan, while the Gokaiger only take one-tenth of a millisecond to transform.
* UngratefulBastard: Played for laughs; Gai gets manhandled by Luka and ''Don'' because of how late his rescue attempt was.
* VersusTitle: In this case, the "Vs." element comes from Gavan arresting the Gokaigers, then the appearance of his EvilCounterpart.
* VisualPun: Gavan slashes at the screen in a certain pattern once the "cross"-over part was mentioned in the narration.
* TheWorfEffect: A downplayed example for the Go-Busters' EarlyBirdCameo; though they don't exactly beat Basco, the fact that the three of them hold their own against someone who has overpowered all six Gokaigers single-handed is certainly impressive. Basco himself even acknowledges that they are pretty good, and chooses to take his leave when he sees that his opening is lost.
