->''"Overdrive, Accelerate!"''
-->--'''[[ByThePowerOfGreyskull Morphing call]]''', ''Power Rangers Operation Overdrive''

The fifteenth anniversary season of ''Franchise/PowerRangers'', taken from ''Series/GoGoSentaiBoukenger''. Legends speak of the ''Corona Aurora'', the Crown of the Gods; an ancient jeweled relic with inconceivable power. According to the myths, millennia ago, two brothers warred with each other in their pursuits of the crown, only for the crown to turn them both into monstrous forms and seal them into planets. Afterward, the crown was taken and its jewels removed, all being sent away to an InsignificantLittleBluePlanet...

In the present day, AdventurerArchaeologist Andrew Hartford has at last found the crown - but the discovery frees the brothers, Moltor and Flurious, from their respective prisons. Realizing that they and other villains would come seeking the crown's power, Hartford uses his wealth to assemble and equip a team to track down and claim the crown's five gemstones before they fall into the wrong hands.

''Operation Overdrive'' has a few quirks compared to a usual Ranger season. For one thing, instead of using mainly self-contained MonsterOfTheWeek adventures, the season tracked the Rangers and villains as they followed a trail of clues around the world to the location of the jewels. It also had a BigBadEnsemble instead of just one BigBad, and they tended to fight each other as much as they fought the Rangers.

One of the more interesting episodes was the [[MilestoneCelebration 15th Anniversary special]] "Once A Ranger" where a new villain comes into play, the son of [[Series/MightyMorphinPowerRangers Rita Repulsa and Lord Zedd]], Thrax. Targeting the [[MetaOrigin Morphing Grid]] itself, they manage to cut the Operation Overdrive Rangers off from their powers. To stop their plan of decimating the entire grid and eliminating all Power Rangers, the Sentinel Knight [[CrisisCrossover commissions Rangers from previous seasons]] to form a new team (all of the Disney-era shows, with one before they took over) [[Series/PowerRangersMysticForce Xander Bly]], [[Series/PowerRangersSPD Bridge Carson]], [[Series/PowerRangersDinoThunder Kira Ford]], [[Series/PowerRangersNinjaStorm Tori Hanson]], and [[Series/MightyMorphinPowerRangers Adam Park]] (most characters were {{Ensemble Darkhorse}}s, the return of JohnnyYongBosch especially was appreciated). In addition, Alpha Six takes on a role. The two-parter involves the Operation Overdrive Rangers worried about being replaced. While not ''quite'' as popular as "Forever Red," "Once A Ranger" has far fewer {{continuity snarl}}s in part because of [[AWizardDidIt Sentinel Knight's involvement]].

Despite this, ''Operation Overdrive'' has a massive negative reputation among the fans, even among the Disney Era seasons. The shift in the overarcing plot was a large departure from traditional Power Rangers fare (which naturally caused some negative feelings [[TheyChangedItNowItSucks due to it being different]]), the acting was a far cry from the quality set by [[Series/PowerRangersSPD SPD]] and [[Series/PowerRangersDinoThunder Dino Thunder]] (though it wasn't as bad as some past and future seasons), the late-season {{Jerkass}} qualities by Mack due to TheReveal were rather inconsistent and unfounded, and the explosion count became '''insane''', topping in at over 250 in the entire show. Thanks to all of this, this commonly is on the top of many "Worst Season" lists.

In recent years though, after everything's cooled down, some fans have admitted there were some good ideas and, compared to ''Mystic Force'', at least managed its characters better (actually focusing on the rangers this time and distributing equal time to the villains. Especially since there are four factions this time). The execution, on the other hand, really hampered the series and brought down what otherwise is a pretty decent globe-trotting adventure story.

It should be noted that while ratings for this season started out good, the ratings would go on to [[IncrediblyLamePun crash and burn]] - a trend that the [[Series/PowerRangersJungleFury two]] [[Series/PowerRangersRPM final]] Disney seasons never really recovered from.

Succeeded by ''Series/PowerRangersJungleFury''.

* AvengersAssemble
* AvengingTheVillain: Thrax, avenging parents Rita and Zedd.
** Who are, notably, not actually dead, per se. But they pulled a HeelFaceTurn and he didn't, so they're dead to ''him''.
*** Well, their HeelFaceTurn was forced onto them by Zordon's good energy. So, technically, the good guys "killed" who they once were, and what they were clearly like when Thrax was born, given his appearance.
* BadassNormal: {{Lampshaded}} by Adam in "Once A Ranger", as the only Ranger without a civilian superpower.
* BecomeYourWeapon: Sentinel Knight merges with the sword Exelsior. Later both merge with Mack for his Battlized mode.

* CainAndAbel: Moltor and Flurious
* ChekhovsGun: The mummy case in the Hartford's living room, which is [[spoiler: where the last Corona Aurora jewel is conveniently hidden]].
* CloudCuckoolander: Dax
** Also Bridge in "Once A Ranger", when he mentions that the S.P.D. Rangers were mentored by a dog, and that ''his'' superior was a bird. [[StrangeMindsThinkAlike Only Dax thinks it makes sense.]]
** TheCuckoolanderWasRight: Of course, the ''audience'' only knows the explanation was entirely accurate because we watched ''Series/PowerRangersSPD''.
* ContinuityNod: When making the Defender Vest, Hartford says he acquired a dragon scale from [[Series/PowerRangersMysticForce a guy in Briarwood named Toby]].
* CoolCrown: The Corona Aurora.
* CosmicKeystone: the Corona Aurora

* TheDitz: Norg
* DeathSeeker: Mack, once he learns of his true nature. He doesn't use the "d" word, obviously. NeverSayDie.
* DespairEventHorizon: [[spoiler: The Rangers themselves, after Thrax cuts them off from the Morphing Grid in "Once A Ranger". Seemingly subverted when they're reminded that they still have their genetic powers to fight, but [[DoubleSubverted fall into this when they prove to be ineffective]]. And then there's Mack finding out he isn't human.]]

* DrillTank: Drill Driver
* ElaborateUndergroundBase
* ElementalRivalry[=/=]FireWaterJuxtaposition: Between Moltor and Flurious.
* EnfanteTerrible: Thrax, who is quite the evil mastermind for someone whose age is between seven and nine.
* EverythingIsOnline: Kamdor zaps the [=DriveMax=] Megazord with a computer virus, which spreads to the base [[spoiler: and to Mack.]]
* EvilerThanThou
* {{Expy}}: Flurious and Moltor seems to be based on The Miser Brothers, since they are brothers who hate each other as well as the fact that Flurious is ice and Moltor is fire.
* FakeDefector: Will in "Both Sides Now", complete with ShootYourMate (though what Kamdor doesn't know is that he's shooting a ''teleportation'' beam).
* FakeMemories: [[spoiler: Mack]]
* FunWithAcronyms: The Special Hydro Aero Recon Craft is just one {{Xtreme Kool Letter|z}} away from it.
* GottaCatchThemAll: The show revolved around the five jewels to a magical crown (other artifacts empowered by them were clues, but also powerful themselves.)
* GratuitousSpanish: One of the artifacts is named the "Piedra Aztec del Compás". Following proper Spanish grammar, it should be named the "Compás Azteca de Piedra".
* HorribleJudgeOfCharacter: Norg.
* HumanAliens: Tyzonn and Vella.
* IdiosyncraticEpisodeNaming: as Bruce Kalish's third season, every title had three words.
* IfItSwimsItFlies: Sub Driver uses Dump Driver to cleverly avert this.
* IneffectualLoner: Will, at first. He ends up becoming an ''Effectual'' Loner.
* InfinityPlusOneSword: The Sentinel Knight ends up possessing one.
* InnocuouslyImportantEpisode: "One Fine Day" [[spoiler:First hint that Mack isn't quite human as he thinks...]]

* TheJeeves: Spencer
* JumpedAtTheCall: Mack
* LawOfInverseRecoil: Averted for once; the Drill Blaster requires the Defender Vest to counter its recoil.
* LegionOfDoom: Thrax, son of [[Series/MightyMorphinPowerRangers Rita Repulsa and Lord Zedd]], uniting the four villain factions in "Once A Ranger".
* {{Leitmotif}}: Each villain faction gets their own theme music.
* LinkedListClueMethodology
* LotusEaterMachine: The "Home and Away" two-parter has Tyzonn put into one of these by Crazar. He's made to believe that his fiancé is still alive, he was never mutated into a Lava Lizard, and the entire season never took place.
* MasterOfDisguise: Spencer
** LatexPerfection: Gets ridiculous[[note]]ly awesome[[/note]] when he impersonates ''Ronny''.
* MeaningfulName: Rose the Pink Ranger
* MeetCute: Weaponized version used by Miratrix to lure Dax.
* MilestoneCelebration[=/=]ReunionShow: "Once A Ranger"
* MookPromotion: Moltar holds a deathmatch between his Lava Lizards. The strongest one turned into the MonsterOfTheWeek, Volcan.
* [[TheMountainsOfIllinois The Mountains Of Florida]]
* MrExposition: Rose, the genius, is Ms. Exposition.
* MultinationalTeam
* MyBiologicalClockIsTicking: male example with ''Hartford''
* MythologyGag: All of ''Boukenger'''s monsters were homages to previous seasons' HumongousMecha. It doesn't ''fully'' translate to ''Operation Overdrive'', between homages to seasons that never made it overseas and American-designed monsters that don't homage anything, but still.
** TheOneWith Mjolnir seems to have one involving actual mythology: One Norse tale has Thor crossdressing and posing as Freya to get Mjolnir back. ''Operation Overdrive'' has [[strike:Ronny posing as Freya]] Spencer crossdressing and posing as Ronny-as-Freya to get Mjolnir back.
* {{Nerdgasm}}: {{In-universe}} example -- Ronny seems to have a "zordgasm" seeing the zords for the first time. And then another one when she checks out the Drill Blaster. All for the sake of adapting Natsuki's [[GenkiGirl genkiness]] into her...
* TheOneTrueSequence: Used and abused.
* OneWingedAngel: Almost all the villains. Flurious gets the funky chess-piece-looking thing, Miratrix becomes a giant monster bird, the Fearcats get their armored forms, and Kamdor... uh... opens his face mask to reveal another one. Hey, they can't ''all'' be winners. But if we don't count Norg as a real villain, Moltor is the only Overdrive villain who never gets an upgrade. Then again, you might consider his usual form the upgrade of his apparently-human form from flashbacks.
* OperationBlank: Of course.
* OrcusOnHisThrone: Flurious does next to nothing for most of the season.
* OurGhostsAreDifferent: Brownbeard's ghost has the standard ghostly abilities of turning [[{{Invisibility}} invisible]] and [[DemonicPossession possessing someone]], but he can also conjure a sword from out of thin air, and seems to be solid most of the time, being able to hold objects, and can even be put at risk from a monster attack. [[spoiler:Oh, and he gets a shave at the end of the episode.]]
* OurHomunculiAreDifferent: The Fearcats create a giant homunculus called "Agrios" by combining three relics within the Octavian Chalice.
* PinocchioSyndrome: [[spoiler: Mack]]
* PublicDomainArtifact: Thor's hammer Mjolnir (originally in ''Boukenger'' as Uchide's mallet, another Public Domain Artifact)
* RagtagBunchOfMisfits: A race car driver, a stuntman, a ClassyCatBurglar, a perpetual grad student and a RichIdiotWithNoDayJob team up and save the world. [[SixthRanger Then joined]] by the ElementalShapeShifter HumanAlien from Mercury.
* RecruitingTheCriminal: Will. It's never spelled out wither or not he's a ReformedCriminal when the series starts, but during his ten-minute retirement in ''Once A Ranger'', he's shown working as a security consultant. It takes a thief and all that.
* [[spoiler: RidiculouslyHumanRobot: is Mack ever one.]]
* [[spoiler:RoboticReveal]]
* SealedCastInAMultipack: It may be an example; as almost every member of the BigBadEnsemble was sealed away before the series started. Not that anybody ''wanted'' to unseal more: two were released by the discovery of the series' MacGuffin, two were freed by allies and ''then'' got caught up in the conflict, and one freed himself.
* SealedEvilInACan: All four big bad factions has someone sealed inside a different can. Moltor and Flurious were sealed inside two lifeless planets, one of extreme heat and the other of extreme cold respectively, when they tried to grab the season's MacGuffin, and freed when said MacGuffin was discovered on Earth. Kamdor is initially sealed in a blue gem necklace until he is freed with a stolen device by his partner Miratrix, who incidentally later becomes sealed in same said necklace when Kamdor double crosses her. Then there is the "Prison Mirror" which contains an army of Fearcats, but was destroyed with only Benglo escaping. In another episode, Thrax, the son of Rita and Zedd, repeats the same line his mother made when released from a Space Dumpster, after what could not have been more than two or three years.
* ShesAManInJapan: Crazar, from the episode "Red Ranger Unplugged", was originally a male Ashu named Ouga who appeared in Tasks 40 through 42 of ''Boukenger'' (the "[[TakenForGranite petrified]] Eiji" min-arc).
* SingleStrokeBattle: Kamdor's last stand vs. Will. At least, it came down to one of these after an entire episode of fighting it out.
* ShoutOut: Every monster is designed to look like a previous Megazord, albeit in abstract (this is a carry-over from Boukenger, which was a big milestone celebration series).
* StuffBlowingUp: At one point, Mack and Moltor ''pointing'' their weapons at each other caused enormous explosions.
* [[SuperEmpowering Super Re-Powering]]: Sentinel Knight, at least in "Once A Ranger".
* SurvivorGuilt: Tyzonn
* SymbologyResearchFailure: In mashing up San Diego and Los Angeles into "San Angeles", the creators probably didn't realize they were naming their city "Saint Angels".
* {{Tagline}}: On Creator/ABCKids, various commercials for ''Power Rangers Operation Overdrive'' used the phrase "Kick into overdrive!" at one point or another, sounding similar to the "Shift into Turbo!" [[ByThePowerOfGreyskull morphing call]] from ''Series/PowerRangersTurbo''.
* TakeMyHand: Mack to Will.
* TeenGenius: Rose
* TenMinuteRetirement: [[spoiler: The Rangers, ALL of them, after fully reaching their DespairEventHorizon (having to be saved by veteran Rangers) decide to go back to their lives (save for Mack) in the first part of "Once A Ranger".]]
* ThemeTuneRap: Complete with such [[WordSaladLyrics nonsensical lyrics]] as "Five fingers pointing to the sky in five ways! Five Rangers walking through the sun for five days!"
* TheyCallMeMisterTibbs: [[strike:Mr. Hartford]] Andrew
* ThisIsADrill: the Drill Driver and the Drill Blaster.
* TimeAbyss: ''Power Rangers'' has long had aliens who talked about thousands of years ago as if it was yesterday, but the Sentinel Knight takes the cake: the continents were one when he scattered the jewels, which means he was known to be active ''250 million years ago'', ''and'' lived until at least a few years back when he sealed Thrax; doubtlessly a series record.
* ToTheBatpole
* ToMakeALongStoryShort: Bridge in "Once A Ranger"
* TomatoInTheMirror: [[spoiler: Mack]], again
* [[spoiler: TrulySingleParent]]: Hartford
* VillainTeamup: not frequently, but it's still there. Almost immediately followed by...
** ChronicBackstabbingDisorder
* VolcanoLair: The villain Moltor heads his operations inside one of these, in sharp contrast to his brother Flurious, who resides inside of an icy cave lair.
* WHAMLine: [[spoiler:"We decided to leave Operation Overdrive."]]
** [[spoiler: (After a computer virus infects the base - "Good thing. Good thing. Good thing..."]]
* [[WhatWouldXDo What Would Zordon Do?]]: Alpha in "Once A Ranger"
* WrenchWench: Ronny
* YouAreAlreadyDead: The aforementioned SingleStrokeBattle ends with Will seemingly collapsing and Kamdor walking away... only to explode on the spot.
* YouLookFamiliar: Subverted; Kelson Henderson returns yet again, as confirmed in the opening credits, but thanks to the Yeti suit and yet another vocal characterization (he's Norg), it's impossible to recognize him.
* YoungerThanTheyLook: [[spoiler: Mack]], being [[spoiler:an android]], has had the physical appearance of a 17 or 18 year old since his 'birth' [[spoiler:(or in his case, design)]].
* YourPrincessIsInAnotherCastle: or rather, Your Jewel Is In Another Location.
