''Kikai Sentai Zenkaiger'' (roughly translated as "Mecha-World Squadron Zenkaiger[[note]]"Zenkai" in katakana form can be translated in English as both "full-throttle" and "all-world"[[/note]]") is the 45th entry in the ''Franchise/SuperSentai'' franchise and the third series in the Reiwa Era. It began airing alongside ''Series/KamenRiderSaber'' on March 7, 2021, following a prequel movie triple-billed with that of the ''Series/MashinSentaiKiramager'' and ''Series/KishiryuSentaiRyusoulger'' movies on February 20, and later, ''Series/KamenRiderRevice'' in the Series/SuperHeroTime block. It is the 45th anniversary season and the second crossover ''Sentai'' season after ''Series/KaizokuSentaiGokaiger''.

* RunningGag: The [[{{BFG}} Zenryoku Zenkai Cannon]]'s [[RecoiledAcrossTheRoom recoil being so strong]] no one's able to handle it.
** On Zenkaizer's initial use, he did get RecoiledAcrossTheRoom. He tries to prevent this from his next use onwards by using his heavy Super Zenkaizer form, with the rest of the Zenkaigers supporting him from behind in a human train formation, but even then ''everyone at the front (sans [[TheBigGuy Zenkai Vroon]])'' gets blown off their feet into the air.
** In episode 32, Kaito in Stacaesar's body uses it and also gets RecoiledAcrossTheRoom. It conveniently causes him to drop the weapon which allows Zenkaizer to retrieve it when he returned to his body.
** In episode 36, Zenkai Juran was lent the weapon, but as he [[GenreSavvy starts getting cold feet]] over the recoil he hands it over to Zenkai Vroon to handle better while everyone held onto him waist-down to stabilize him. Unfortunately, everyone forgot Zenkai Vroon has a DetachableLowerHalf ability, causing his free-moving upper half to get blown away from the recoil instead.

* {{Camp}}: This series is one of, if not the most campiest Sentai ever. Featuring many wacky characters, zany [[MonsterOfTheWeek plots of the week]] and the ''very'' hilarious OutsideTheBoxTactic to resolve them.

*** Gear #33 - ''Series/SamuraiSentaiShinkenger'' - Allows the Zenkaigers to perform Twokaizer's ''Shinken Issen'' FinishingMove.

The ''Super Sentai'' exist in multiple [[AlternateUniverse parallel worlds]]. One of these worlds is Kikaitopia, a once-peaceful land of RidiculouslyHumanRobots called Kikainoids, now under the tyranny of the [[TheEmpire Kikaitopia Dynasty Tozitend]], who seek to seal all the other worlds in order to rule over TheMultiverse, with an Earth that has somehow [[WhenDimensionsCollide merged with a part of Kikaitopia]] being their last target. To prevent this and save the worlds already dominated by the Tozitend, Kaito Goshikida, a young human whose parents went missing after discovering the multiverse, teams up with four rebelling Kikainoids to face them. Harnessing the powers of all 44 previous ''Super Sentai'', they transform into the 45th team, Kikai Sentai Zenkaiger, fighting at full-force, full-throttle!

*** Gear #42 - ''[[Series/KaitouSentaiLupinrangerVsKeisatsuSentaiPatranger Kaitou Sentai Lupinranger/Keisatsu Sentai Patranger]]'': Activates the finishing blast of either team. Depending on the Gear used, the attack is shaped as the respective team insignia. Magazine scans also show that the Lupinranger Gear can be used for MasterOfUnlocking and WireFu abilities, while the Patranger Gear provides SuperToughness and ImprobableAimingSkills, [[InformedAbility but these were all not used in the series proper]]. The Patranger Gear is later used in the series proper to perform a FusionDance for its targets.

*** Gear #46 - ''Avataro Sentai Donbrothers''[[note]]Announced by the Geartlinger as ''Shin-ban/新番/"New Number"! New hero!''[[/note]]: A unique Gear shaped like an Avataro Gear. Summons Don Momotaro and his CoolBike Enya Rideon.

** Stacaesar uses the Geartozinger, which is a knockoff of the ''Geartlinger'', as his main weapon. While the Geartlinger merely grants its user various abilities and weapons of the Sentai it summons, the Geartozinger summons an EvilKnockoff of the Sentai or its mecha depending on the circumstance.
** Twokaizer uses the World Plunderer Transformation Gun Geardalinger, a MixAndMatchWeapon that can switch between its gun and sword modes. It's also a tambourine, which while mainly used for his transformations, is also occasionally used to plant targets on his opponents for his anchor-shaped HomingLasers fired at the end.

** Episode 9 adds as much Twokaizer-related stuff to the EvolvingCredits as possible, including Twokai-Oh - the only one not appearing that week.
** Far more than a "cameo", Don Momotaro becomes a recurring character in the last few months of ''Zenkaiger'' before his own show, ''[=DonBrothers=]'', debuts.

*** Gear #07- ''Series/KagakuSentaiDynaman'': Grants its user(s) use of {[=DynaPink=]’s [[FinishingMove Rose Finale]].

* '''Stacy/[[purple:Stacaesar]]''' (Purple): A [[HalfHumanHybrid half-human Kikainoid]] and son of Tozitend general Barashitara. Originally serving them as their [[ThePsychoRangers Psycho Ranger]], he joins the heroes as an EleventhHourRanger in the final battle.

** When Great Mukaikaze Wald gets finished in episode 43, he yells out "''[[Anime/GaoGaiGar KAZE NI NAREEEE!]]''" To put it into perspective, he is voiced by Creator/NobuyukiHiyama. Also doubles as a MythologyGag to Series/NinpuuSentaiHurricaneger as it is the closing lines of the opening song.

*** Gear #17 - ''Series/GoseiSentaiDairanger'': Grants its user(s) the Dairen Rods. For Twokaizer, it grants him the Byakkoshinken to perfrom the ''[[SensoryOverload Howling New Star Scattered Echo]]'' move.

*** Gear #46 - ''Avataro Sentai Donbrothers''[[note]]Announced by the Geartlinger as ''Shin-ban/新番/"New Number"! New hero!''[[/note]]: A unique Gear shaped like an Avataro Gear. Summons Don Momotaro.
