It happened without warning. Countless worlds found themselves trapped within small machines, unable to resist. And the last world to be targeted is...

Kikai Sentai Zenkaiger (roughly translated as "Mecha-World Squadron Zenkaigernote ") is the 45th entry in the Super Sentai franchise and the third series in the Reiwa Era. It began airing alongside Kamen Rider Saber on March 7, 2021, following a prequel movie triple-billed with that of the Mashin Sentai Kiramager and Kishiryu Sentai Ryusoulger movies on February 20, and later, Kamen Rider Revice in the Super Hero Time block, and finished its run on February 27, 2022. It is the 45th anniversary season and the second crossover Sentai season after Kaizoku Sentai Gokaiger.

The Super Sentai exist in multiple parallel worlds. One of these worlds is Kikaitopia, a land of Ridiculously Human Robots called Kikainoids, long under the tyranny of the Kikaitopia Dynasty Tozitend, who seek to seal all the other worlds in order to rule over The Multiverse, with an Earth that has somehow 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!

In a franchise first since Denshi Sentai Denziman and Taiyou Sentai Sun Vulcan, Zenkaiger is followed up by a semi-sequel series, Avataro Sentai Don Brothers.


Recurring Super Sentai tropes:


Kikai Sentai Zenkaiger provides examples of:

  • Absentee Actor: Tatsuhisa Suzuki retired from production in early August 2021, leading to Gege being reduced to The Voiceless from Episodes 22 to 24. His lines were either filled by the other members of the Tozitend or Stock Audio Clips. Masaya Fukunishi eventually took over for Gege starting from Episode 25.
  • Ascended Meme: Upon Twokaizer's reveal in Japan, his resemblance to the Gokaigers actually ended up getting GokaiGold trending in Japan instead of his actual name. Episode 9 has his resemblance to the Gokaigers be poked at, justifying as an in-universe rip-off.
  • Beach Episode: Episode 24 has our heroes relaxing and chilling at a beach... with Vacance Wald, aka the MOTW.
  • Borrowed Catchphrase: Much like has been seen with legacy items in Kamen Rider, the Zenkaigers tend to call out the catchphrase of past Sentai heroes, primarily the Red Rangers, when using their team's Gear.
    • In #1, Juran evokes Takaharu Igasaki / AkaNinger's catchphrase of "I'm fired up!" ("Moete kita!") whilst using the Ninninger Gear.
    • In #3, Kaito, when utilizing the ToQger Gear, uses Right Suzuki / ToQ #1's "All aboard!" ("Shuppatsu shinkou!") line just before the "train" consisting of the Zenkaigers takes off. Juran then uses the ToQ Changer's "please wait behind the white line" when they are blitzing through the Kudacks.
    • In #5, Kaito uses Lucky / Shishi Red's catchphrase "Talk about lucky!" ("Yosha lucky!") when the Kyuranger Gear gives him good luck.
    • In #6, Magine invokes Hiromu Sakurada / Red Buster's catchphrase and pose ("Ready, go!") when she uses the Go-Busters Gear.
    • In #8, Kaito yells Juuru Atsuta / KirameiRed's catchphrase "Hirameki~ng!" whilst using the Kiramager Gear.
    • It even applies to crossover abilities. In #20, Juran uses the Kamen Rider Zi-O Gear, and says Sougo's catchphrase "I think I can do this!" before performing a finisher, while Kaito uses the Kamen Rider Saber Gear, and borrows Touma's "I decide how this story ends!" line.
  • Black Comedy: Episode 18 has an absolutely glorious scene in where Sentai Gear #15 (Choujin Sentai Jetman) enacts a Shot-for-Shot Remake of the finale of said series, including Gai's death. While in Jetman, it's played completely seriously, Zenkaiger's rendition of it is so melodramatic and absurd that it ends up becoming one of the most hilarious moments of the series.
  • Breaking Old Trends: Fittingly for the series's theme of being the "World's First", to say that Zenkaiger breaks quite a few rules for Sentai would be a bit of an understatement.
    • This is the first series that heavily strays from the standard "(mostly) human team" formula, featuring only one human (later joined by a Human Alien) while the rest of the team are humanoid aliens who are not given any (permanent) human form to assume the disguise of.note 
    • While not the first to have White as the leader, it is the first to have White as the lead viewpoint character instead of Red.
    • On the subject of Kaito, he is the first non-red to take part in the traditional send-off.
    • This is the first team with highly individualistic Ranger forms that share almost nothing in common with each other.
    • While not the first Sentai series to be followed up by a connected sequel (that honor goes to Denshi Sentai Denziman), it is the first to have the technology for the next series be actively worked on in parallel with the current story (with Isao Goshikida directly producing Sentai Gear #46 as used by DonMomotaro rather than a separate gear that fits into the Geartlinger), and to have the Early-Bird Cameo for the next series be incorporated into the show's endgame.
    • Averted for its place in the Reiwa Era. They're not the first Reiwa Sentai, that honor goes to Kiramager.
  • Call-Back:
    • Zenkai Juran, Zenkai Gaon, Zenkai Magine and Zenkai Vroon are all call-backs to 4 mechas (Daizyuzin, GaoKing, MagiKing, and DaiBouken respectively) that the Go-Busters' mecha transformed into in the climax of their movie with the Gokaigers via mecha Gokai Changes.
    • The main team being composed of one Token Human and four non-human aliens from a parallel dimension was done before in the previous anniversary series, though the Zyumans were given human forms as disguises by their transformation devices.
  • Casting Gag:
    • While this isn't the first time Tatsuhisa Suzuki has voiced a robotic assist character, Gege isn't exactly the shining image of good.
    • The first episode has Kaito being asked if he's trying to bungee-jump off of the Tokyo Skytree for YouTube, which he denies. Kiita Komagine, on the other hand, has a fairly active YouTube channel.
    • The Geartlinger's finisher is announced as "Hero/Kikai! Super Zenkai Time!". Lenne Hardt, the voice of the Geartlinger, was previously the opening and closing announcer for the Super Hero Time Kids Block on TV Asahi from 2005 to 2007.
    • Tomokazu Seki voices the Gokaiger-based Twokaizer's Geardalinger, having previously been the system voice for all of the Gokaigers' own equipment.
  • Cerebus Retcon: Gaon's Boomerang Bigotry was usually Played for Laughs for most of the series, mostly in how he interacts with his teammates. Episode 22 has Juran finally confront him for his bigotry, making him realize how deeply harmful his bigotry can be against the team's goals.
  • Cerebus Rollercoaster: Zenkaiger's wacky sense of humor often gets juxtaposed by genuine, heartfelt moments and emotional scenes. When it's not heartfelt, it dips into a more horror-esque tones as it delves into the lore.
  • Close on Title: Episode 49 ends with the episode's title being shown followed by the show's logo.
  • Couch Gag:
    • The episode title card has a different effect each episode. Some are more subtle than others.
    • The quick shots in the OP of all five Zenkaigers in combat, and then hanging out at the Colorful candy shop, are done differently each week - there's even a Brick Joke of sorts when one shot in episode 4 shows Colorful completely empty, only for later episodes to reveal that it's because they're all playing hide and seek. Starting from episode 9, a shot with Zocks's siblings is added to the mix.
  • Crossover Alternate Universe: The Gokaiger World is implied to be one; a recurring depiction of all the Sentai Worlds being sealed into Gears has them being represented by team images, the Gokaigers' showing them standing in front of all their predecessors. This indicates that the Gokaiger World has their own versions of the first 34 Super Sentai, justifiable since Gokaiger itself hinges on their existence. It may also include post-Gokaiger Sentai, since the various crossovers since then, most notably Super Sentai Strongest Battle, had to have happened somewhere.
  • Denser and Wackier: Zenkaiger is this to the Lighter and Softer Kiramager, with its far more outlandish characters (on both ends no less), absurd comedy, and overall propensity for bizarre occurrences thanks to the Walds. So far, the series doesn't really try to take itself too seriously, aside from the more serious moments that pop up (and even then, they tend to get Mood Whiplash soon after).
  • Early-Bird Cameo:
    • Episode 9 adds as much Twokaizer-related stuff to the Evolving Credits as possible, including TwokaiOh — which doesn't actually debut until Episode 12.
    • Don Momotaro guest-stars in Episode 42, a few months before his own show, DonBrothers, debuts.
  • Eiffel Tower Effect: In full force in episode 8, when the Door Wald uses a randomised Portal Network to send our heroes across the world in every direction imaginable, and always within view of all the landmarks that come under this trope, even some lesser known ones like the Marina Bay Sands and Merlion in Singapore.
  • Family Theme Naming: The Goshikida family are all one big Internal Homage to Super Sentai; in addition to the Meaningful Name referencing the archetypal Sentai, Kaito's parents are named after Himitsu Sentai Gorenger's theme song singers Isao Sasaki and Mitsuko Horie, while his grandmother Yatsude takes after Sentai producers' collective pen name Saburo Yatsude.
  • Fantastic Racism:
    • Despite most people adjusting to the sudden appearance of Kikainoids on Earth, they quickly grow fearful of them once the Tozitend Dynasty invades, leading to Juran being shunned by a group of humans in episode 1 when he tries to fend off a Kudaiter general. Unusually for this trope, the dust settles in about a week and Kikainoid civilians have successfully integrated into society, even finding jobs... and love.
    • This is Played for Laughs with Gaon, who loves animals to the point of shunning his own race because they aren't as cute and fluffy as the animals (and humans) of Earth. It gradually becomes more Played for Drama as the series goes by, coming to a head in Episode 22 as Juran confronts Gaon about his bigotry, inadvertently unlocking his Jerkass Realization and Character Development.
  • Fusion Dance: Super Warumono Wald appears to be made up of several Sentai Big Bads.
  • Gratuitous English: Used fairly liberally within the series, even more so than previous Sentai series. Juran's the most guilty of this, often saying random English words such as "maybe" in conversation. The Goldtsuikers often use English as well, sometimes even combining Japanese and English such as sarabye.
  • Have You Told Anyone Else?: Textbook example in episode 4, when Ijirude learns about the captured worlds being liberated every time a Wald is struck down, from Vroon of all people.
  • Legion of Doom: The first movie has one including Baseball Mask, Bio Hunter Silva, Yaiba of Darkness, Kingon of the Bigfoot, Damaras, Basco, Sally, General Schwartz, Kyuemon Shingetsu Kibaoni, Raizo Gabi, Quval, Bangray, Eridoron, Destra Maijo and Zamigo Delma, flanked by Mooks from every Sentai show.
  • Meaningful Name:
    • The Goshikida family name contains the kanji for "five colors".
    • Kaito's is a special case, taking the kanjis "da/田" and "kai/介" and combining them forms an alternate "kai/界", which means "world", giving his full name an alternate meaning of "Five-Colour World Person/五色界人".
  • The Multiverse: In the setting of this series, each past Super Sentai takes place in their own universe, along with many other parallel worlds. The Tozitend conquered all of these worlds and has their sights set on the world of the Zenkaigers. However, something went wrong with their invasion, preventing the instant victories they'd grown used to and yanking a chunk of Kikaitopia into that world with them. The crossover with Saber adds the Kamen Rider Shared Universe into the mix, it being revealed that the Tozitend missed this one universe.
  • Mythology Gag: Has its own page. Since Zenkaiger is the 45th anniversary of Super Sentai, it's safe to expect many homages to past Sentai series.
  • Nice, Mean, and In-Between:
    • The three male human leads form this dynamic. Kaito is a Nice Guy who's a bit dense (nice), Zocks is an Unscrupulous Hero who does keep his word (in-between, though he can lean on mean), and Stacy is a stoic soldier who's aligned with the Tozitend (mean).
    • The three main factions since episode 8: the Zenkaigers are straight heroes who fight to protect everyone no matter what (nice), the Goldtsuikers are anti-heroes who fight against the Tozitend for their own goals (in-between), and the Tozitend are the main bad guys of the story (mean).
  • Non-Standard Character Design:
    • While Zenkaizer is fairly normal, if ornate, the rest of the Zenkaigers are very obviously mechanical and far more armored than usual, looking more like Metal Heroes.
    • The inverse also applies within the team; as Zenkaizer is the Token Human while his form is based on a Cool Plane instead of a proper humanoid mecha, he comes off more like a Ranger-shaped Anthropomorphic Personification than a Robot Soldier like the rest of the team is.
  • Non-Uniform Uniform: Even moreso than the Kyurangers. The Zenkaigers share almost nothing common between their ranger suits, barring the numbered "V" on their foreheads and their Zenkai Buckle belts (and even so it seems only Zenkaizer's and Twokaizer's work as an actual Gear holder).
    • There is a minor downplay between Zenkai Juran and Zenkai Gaon, thanks to Kibbles and Bits. Both of their suits feature a creature head-shaped torso, clawed feet, similar forearm armor, a backpack-like armor on their backs (which each forms half a hip of Zenkai-Oh), and Shoulders of Doom with their unique emblems emblazoned on it (which forms the chest of Zenkai-Oh).
  • Ocular Gushers: Magine does this in episode 3 when she gets reunited with her old friend Zyuran.
  • Oddball in the Series: It is safe to say that this time, the rulebook has not only been thrown away, but trashed and burnt to nothingness. Normally, there are multiple rangers who can summon mecha. This time however, there's just one human ranger, and the rest of the team are the mecha. While it is not uncommon for someone other than the red ranger to be the leader, they still tend to be the The Face of the team or take some kind of protagonist role, while Zenkaizer, the white ranger, takes this role instead (though he technically wouldn't be the first).
  • Off-the-Shelf FX:
    • Stacaesar's summoning of past Super Sentai mecha is done through using their official toy packagings as a medium to come out of.
    • In episode 17, when Juran's half of Zenkai-Oh JuraGaon is turned invisible, Gaon's half is portrayed by the DX toy.
    • Happens again in episode 41 where more DX toys were used to portray all the Zenkaigers breaking their Combining Mecha formations because of disputes over noodles caused by the Monster of the Week.
  • Once per Episode:
    • The opening, once it nears the end, has a short segment that varies between episode to episode. It's usually showing the gang doing random things within the shop and interacting with each other.
    • The first four episodes featured an entire battle sequence taking place within an explosion, usually as a Curb-Stomp Battle in favor of the Zenkaigers.
    • Almost every episode has a team roll-call that is completely distinct from one another, whether through visual gags or actions. Compare the rollcalls from episode 1 and episode 5, which both feature Zenkaizer and Zenkai Juran, yet they do the pose and shouting differently.
    • Every episode after the first always starts with Setchan stating a Previously on… segment. Each has their variation and gag, like Setchan looking away before facing the audience, flying around haphazardly, or even busting in a seemingly empty room just to say his catchphrase.
  • Personality Powers: The Zenkaigers' personalities somewhat reflect the nature of the Sentai powers they represent.
  • Phlebotinum Rebel:
    • The Zenkaigers are mostly comprised of Kikainoids, who hail from the same dimension as their evil overlords, the Tozitend, and seek to rebel and defeat them in order to save all the worlds.
    • The Tozitend use the evil Toziru Gears for their schemes, while the Zenkaigers use the same technology-based good counterpart, the Sentai Gears. This was lampshaded in episode 2, when both sides learn that they all use Gears to fight. It's no wonder when it turns out Ijirude actually ripped off the Goshikida scientists' technology.
    • This gets used against the Zenkaigers when Ijirude additionally creates the Geartozinger and Dark Gears based off the Zenkaigers' equipment to directly counter them.
  • Product Placement: Colorful prominently hosts Bandai branded Capsule Station gashapon machines, as well as a number of actual Bandai-produced snacks and candies.
  • Reckless Gun Usage: Well, it's the Geartlinger, but more the same. Magine in the third episode points the Geartlinger near her face, coming close to accidentally shooting herself.
  • Retraux: Zenkaiser has holes in his visor, reminiscent of Gorenger and JAKQ's helmets. The holes were needed back then due to the way the visors were made, but nowadays a visor can be any color and still let the suit actor see out of itnote . This just ups the homage aspects towards those two series even more.
  • Rhyming Names: Kikai Sentai Zenkaiger. Also in that they deal with parallel worlds, also known as "sekai", while episode titles play with the word "kai".
  • Running Gag:
    • Almost every episode features a unique non-standard In the Name of the Moon rolecall, usually due to our heroes being influenced or inconvenienced by the Monster of the Week's effects.
    • The Zenryoku Zenkai Cannon's recoil being so strong no one's able to handle it.
      • On Zenkaizer's initial use, he did get Recoiled Across the Room. 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 Zenkai Vroon) gets blown off their feet into the air.
      • In episode 32, Kaito in Stacaesar's body uses it and also gets Recoiled Across the Room. 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 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 Detachable Lower Half ability, causing his free-moving upper half to get blown away from the recoil instead.
  • Shout-Out:
    • In his initial Behemoth Battle, JuranTyranno can be seen using his Breath Weapon to propel himself towards the enemy in a fashion similar to another prehistoric reptile.
    • Episode 2 has an homage to the Galatica Magnum punch of Ring ni Kakero when Kinoko Wald does his Galactica Mushroom Megaton Punch towards Juran.
    • Boxing Wald's last words references Tomorrow's Joe's narration of the final scene.
    • Stacy's summoning of past Sentai through the Darkness Gears is very akin to Kamen Rider Diend's summoning of past secondary Kamen Riders through the Kamen Ride cards, all the way down the transformation device in the shape of a gun.
      • Similarly, a dark counterpart of the hero, who transforms into a form mostly dominated by black and purple by pointing the gun on his hand? Sounds like Chase.
      • The Darkness Gears also bring to mind the Another Ridewatches. Both have uniform purple edges to distinguish them from their heroic counterparts, and when used produce low-pitched versions of the typical announcements.
    • When Zocks arrives for the first time in episode 8, his ship CrocoDaiOh emerges from dark clouds and is illuminated by lights. It's practically the same shot they used for Space Sheriff Gavan whenever Dolgiran is summoned.
    • Episode 11 has Cutanner and Ricky arguing over whether anpan or cream puffs are better. To try and defuse the argument, Kaito suggests combining the two, doing so in a way that evokes Pikotaro's PPAP/Pen-Pineapple-Apple-Pen.
    • Episode 15 has Great Retro Wald strike a move that is very similar to Ultraman - the Spacium Ray!
    • After getting stuck between two cars in Episode 16, Vroon says "I'll be back" and gives a thumbs-up in a clear nod to Terminator 2: Judgment Day.
    • Toumei Wald, from episode 17, looks like he's covered in bandages and wearing shades.
    • Episode 18:
      • Two Kikainoids under Renai Wald's thrall act out the iconic "flying" scene from Titanic (1997).
      • Super Renai Wald's special attack is called "Love Me Do".
    • Episode 19:
    • Episode 21:
      • Among the things Copy Kaito and Copy Zocks did during their crime spree are donning Cat's Eye costumes while holding to a grappling hook, and steel gold bars while looking like Lupin III - bonus for featuring both green and red jackets!
      • When ZenKaijuOh is formed, it roars with mostly a dark background with light emanating from its position, much like the reveal shot of Godzilla Junior being the new Godzilla in Godzilla vs. Destoroyah.
      • Similarly, the production notes made it a point to have a background music that mimic the Godzilla March theme for this fight.
    • There's a short range Continuity Nod when episode 28 is about a Manga Wald and episode 29 has a Tennis Wald, and Zocks thinks he can deal with it after having read a manga about tennis. Said manga is a Bland-Name Product of The Prince of Tennis called The Pirates of Tennis.
      • Said Manga Wald also sports a beret. One of the most notable beret-wearing mangaka out there is Osamu Tezuka.
      • Pay attention to the props during the giant mecha fight. A bunch of the manga scattered around references popular titles and artstyles, like a a matador manga featuring Jojos Bizarre Adventure style complete with its popular "menacing" onomatopoeias.
    • Episode 29:
      • Tennis Wald is based on Aim for the Ace! rival Reika, complete with pink clothing and Ojou Ringlets made of tennis balls.
      • Various cut-ins and effects are based on The Prince of Tennis panels.
      • Similarly, the grinding finisher "Satoshi" did against Tennis Wald is the Twist Smash technique Ryoma Echizen (the protagonist of the manga) likes to perform.
    • In episode 33, all of the guys briefly dress up as Japanese Delinquents, and Magine's weapon of choice is a yo-yo.
    • When Great Mukaikaze Wald gets finished in episode 43, he yells out "KAZE NI NAREEEE!" To put it into perspective, he is voiced by Nobuyuki Hiyama. Also doubles as a Mythology Gag to Ninpuu Sentai Hurricaneger, as it is the closing lines of the opening song.
  • Sliding Scale Of Silliness Vs Seriousness: The series is firmly on the "silliness" side most of the time thanks to its copious amounts of slapstick, surreal comedy, wacky characters, and overall sense of light fun. Its most heartfelt and horrifying moments are more of the serious side of the scale.
  • Spell My Name with an "S": A number of names, due to a lack of official Japanese romanisations.
    • Officially it's "Zenkaizer" and "Twokaizer", despite how the word "Kaiser" is spelled.
    • Juran's name was originally assumed to be spelt as "Zyuran".
    • The villains are called "Tojitendo" in Japanese, but spelt as "Tozitend" in English.
    • The mooks: Kudack, Kudakk, or Kuddack?
    • The Monster of the Week are called "Warudo" by Japanese pronunciation, a corrupted shortened form of the word "World/Waarudo". While the logical English equivalent would be along the lines of "Wald", without an official romanisation fans spell it as "World" regardless.
    • Zocks's surname was initially assumed to be "Goldtweaker" by pronunciation, but official spellings vary from "Gorldtsuikar" to "Goldtsuiker".
  • Sudden Name Change: Ijirude initially named his knockoff Sentai Gears as the Ankoku/Dark Gears. Later media properly renames them as the Dark Sentai Gears.
  • Surprisingly Realistic Outcome: A recurring gag in the first two episodes. Kaito is surprised to learn that when you give someone the Geartlinger, their first thought isn't to transform with it, but to just shoot the enemy. It makes sense as the thing would come across more as just a gun than an actual Transformation Trinket at first glance.
  • Two Lines, No Waiting: From episode 15 onwards, there is an ongoing subplot about Stacy hanging around at Colorful as he increasingly questions his reasons for staying with the Tozitend, while the Zenkaigers are busy dealing with the latest Wald's plan.
  • Unspoken Plan Guarantee: The climax of episode 8 hinges heavily on all the four Kikainoids getting the same idea to just physically walk back to Japan.
  • Wham Episode: Episode 34 reveals Hakaizer's true identity to be Kaito's long-lost father Isao.
  • When Dimensions Collide: The series starts off a month after Kikaitopia has overlapped with Earth, bringing the Kikainoids over to our world. The Monster of the Week, Walds, also causes Earth to overlap with the parallel world each of the Walds represent through their own presence.
  • Wing Ding Eyes: Happens to all the good guys during the giant robot battle because of Love World's overwhelming influence.

"Sekai Zenkai! All okay!"

Vroon Gets Blown Away

The recoil on the Zenryoku Zenkai Cannon is seriously strong. So much so that Juran gets cold feet at the prospect of firing it and passes it to the much stronger Vroon. They hold him by his legs, forgetting that he has a Detachable Lower Half, resulting in the recoil sending his top half flying into the distance.

How well does it match the trope?
