History Recap / PowerRangersOperationOverdriveS1E20OnceARangerPart1

** ActionGirl: [[Series/PowerRangersDinoThunder Kira]], [[MakeMeWannaShout the Yellow Dino Ranger.]]

* SuperEmpowering: The Sentinel Knight can apparently do this, since he restores the veteran Ranger's powers (except Bridge, who never lost his Rangers powers).

[This description was copied in violation of our Administrivia/{{Plagiarism}} policy. Please replace it with original writing.]

* HilariousInHindsight: The aforementioned dog mentor and bird superior. Seeing that Adam, one of the Retro Rangers who appeared in [[Film/MightyMorphinPowerRangersOnceAndAlways Once & Always as part of S.P.A., he will at some point come across Birdie and Anubis "Doggie" Cruger]].

* EnfanteTerrible: Thrax, who is quite the evil mastermind for someone whose age is between seven and nine.

In the 15th Anniversary episode, the son of Lord Zedd and Rita Repulsa, Thrax, unites all four Corona Aurora-seeking factions of villains into a new Evil Alliance. When they manage to overwhelm the Overdrive Rangers, their connection to the Morphing Grid is severed, and their powers destroyed! With the gems still needing protecting, Sentinel Knight assembles a team of replacement Rangers, made up of members of previous (or future) teams of Power Rangers. Will they be enough to stop the Evil Alliance? And will the former Overdrive Rangers be able to assist with just their genetically enhanced abilities?

* [[SuperEmpowering Super Re-Powering]]: The Sentinel Knight can apparently do this, since he restores the veteran Ranger's powers (except Bridge, who never lost his Rangers powers).

* SidelinedProtagonistCrossover: There is no returning Ranger who is a Red during the airing of their season. The only Red Ranger they have in their temporary team, [[Series/PowerRangersSPD Bridge]], began as a Green Ranger in his original series and has since been promoted to B-Squad's team leader offscreen. Adam as the ''[=MMPR=]'' Black Ranger leads them, however, because of his seniority.

* TenMinuteRetirement: 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).

** TheLeader: [[Series/MightyMorphinPowerRangers Adam]], [[BadassNormal the Black Mastodon Ranger.]]
** TheLancer: [[Series/PowerRangersSPD Bridge]], [[TheEmpath the SPD Red Ranger.]]
** TheBigGuy: [[Series/PowerRangersMysticForce Xander]], [[GreenThumb the Mystic Force Green Ranger.]]
** TheSmartGuy: [[Series/PowerRangersNinjaStorm Tori]], [[MakingASplash the Blue Wind Ninja Ranger.]]
** ActionGirl: [[Series/PowerRangersDinoThunder Kira]], [[MakeMeWannaShout the Yellow Ptera Ranger.]]

* TimeTravel: The Sentinel Knight can apparently do this too, since he brings Bridge to the present from an unspecified point in the future (though obviously after the events of PowerRangersSPD, since he's been promoted to Red Ranger).

** TheSmartGuy: [[Series/PowerRangersNinjaStorm Tori]], [MakingASplash the Blue Wind Ninja Ranger.]]

** TheLeader: [[Series/MightyMorphingPowerRangers Adam]], [[BadassNormal the Black Mastodon Ranger.]]

* TimeTravel: The Sentinel Knight can apparently do this too, since he brings Bridge to the present from an unspecified point in the future (though obviously after the events of PowerRangersSPD, since he's been promoted to Red Ranger).

* SealedEvilInACan: 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.

* LegionOfDoom: Thrax, son of [[Series/MightyMorphinPowerRangers Rita Repulsa and Lord Zedd]], unites the four villain factions.

* EnfanteTerrible: Thrax, who is quite the evil mastermind for someone whose age is between seven and nine.

* DespairEventHorizon: The Rangers themselves, after Thrax cuts them off from the Morphing Grid. 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]].

** TheCuckoolanderWasRight: Of course, the ''audience'' only knows the explanation was entirely accurate because we watched ''Series/PowerRangersSPD''.

* BigDamnHeroes: The old rangers when the current rangers lose their powers. They forced the baddies to retreat in less than 2 minutes!

* BadassNormal: {{Lampshaded}} by Adam, as the only Ranger without a civilian superpower.
