History Manga / GoGoLoserRanger

* SmartPeoplePlayChess: Parodied. In D's ideal life after conquering Earth, he imagines two Dusters intelligently playing a national-level game of TabletopGame/TicTacToe, the same way one would play ''TabletopGame/{{Go}}'' or ''TabletopGame/{{Shogi}}''.

* WhamLine: During a very ordinary Dragon Keeper stage show, one of the people playing a Keeper mentions that an Invader becoming popular with the citizens would never happen 20 years prior. But the Kaijin Army didn't show up until ''thirteen'' years prior, so that seems off. And if it does to you, you're right; [[spoiler:the guy was referring to the ''original show'' of the Dragon Keepers, not the current Ranger-Kaijin war]].

* ZodiacMotifs: The Kaijin Army's 12 Executives are supposedly themed around the EasternA Zodiac. Seven of them were killed prior to the start of the manga, but the remaining ones are the Snake (Magatia), Rooster (Peltrola), Rabbit, Monkey, and Horse.

** Later in Chapter 52, D happens to come across someone getting arrested under suspicion of being an invader and managed to talk down the police into letting him go. D would later discover [[spoiler: he saved Green Keeper while he was in his civilian clothes.]]

* ShowWithinAShow: The weekly Sunday battles are this. It was hinted and later revealed in Chapter 87 that [[spoiler: the Sunday battles aren't even the original iteration of the Rangers vs. Invaders conflict. At least 20 years prior (seven before the Invaders appeared) there was a non-StagedShooting version of the conflict with regular human actors.]]

** On the flipside, the Rangers are baffled as to how the citizenry have taking a liking to Hwalipon's streams despite him regularly releasing monsters that have a habit of massacring anything it sees.

** Later played straight with Yumeko and Chidori at Green Battalion.
* SocialMediaBeforeReason: Despite the past war the Invaders waged and the repeated massacres from the monsters Hwalipon releases, the human population is feeding into Hwalipon's anti-Ranger broadcasts and is turning against the Ranger Orginization.

** Reds are the leaders, the heroes, and usually have the ego to match. They have a good public face, but they are action first, talk later kinds as well. This can also manifest in a self-centered personality.

** Yellows are smart and [[GadgeteerGenius tech savvy]].

* CondescendingCompassion: Why D [[spoiler:turns his back on the Invader's Rights Association despite absolutely agreeing with their goal; it becomes apparent that the organization doesn't view invaders as equals, but as pitiful beings who can't do anything without human intervention.]]

* SmartPeoplePlayChess: Parodied. In D's ideal life after conquering Earth, he imagines two Dusters intelligently playing a national-level game of ''tic tac toe'', the same way one would play Go or Shogi.

* AllPartOfTheShow: Inverted. The public and ''most of the Rangers'' are convinced the weekly confrontation with the Kaijins is an actual BloodSport where the Kaijins are KilledOffForReal, but in actuality it's a StagedShooting PropagandaMachine made to glorify the Dragon Keepers as the heroes of Earth, while the Kaijins are usually spared from death to be recycled for the following week. To the public, it seems the Kaijins permanently chained their ship to Earth and haven't given up on their invasion for thirteen years, but in reality it was the ''Keepers'' who chained it down to prevent the Dusters from going home in order to keep up the farce. D theorises that the only people who know the truth are only just between the remaining Dusters and the Keepers themselves.

* ChanceMeetingBetweenAntagonists: In chapter 2, just as D discovers Red Keeper's identity through a poster next to an elevator, ''Sosei Akabane/Red Keeper himself'' comes out of the elevator and passes by him.

* DecoyProtagonist: Early promotional materials for the manga indicate the main characters to be the Dragon Keepers themselves, however the plot actually follows VillainProtagonist Duster D, as he sets off on his own plan to infiltrate and defeat the Dragon Keepers from within their ranks. The anime averts this, promoting D from the start.
* DoubleMeaningTitle: ''Sentai Dai Shikkaku'' can refer to the current Keepers, who secretly act like corrupt and immoral people pretending to protect the peace; or it can refer to the team D forms in his qualification test, made up of a group of weak, hopeless people (who even D doesn't want to know the backstory of) who no one expects to move on to the colored rangers.

** For having attempted (and failed) an AlienInvasion on Earth, the Dustards were forced to become the Keepers' permanent {{butt monkey}}s, with their ship permanently chained to Earth and not allowed to return to their home planet.
** [[spoiler:Mook F was mercilessly killed by Red Keeper for coming down to Earth on a non-Sunday. The problem is the poor guy ''wasn't'' even causing any harm in the first place, but was just looking for D, who hasn't came home in days. This also gave the Keepers a reason to deploy Ranger Cadets to guard the Dusters' base to prevent other Dusters from having the same idea of roaming Earth without permission.]]

* GenreDeconstruction: This is used to deconstruct the whole superhero tokusatsu genre from a henchmen perspective. The "Keepers" are nothing more than a bunch of figureheads who are also psychopaths who repeatedly kill the Duster {{mooks}} just so people can praise them long after the actual battle ended just for glory, and are even willing to kill their own just to stay on top. Meanwhile, the main character, a Duster named D, while sympathetic due to circumstance, is a VillainProtagonist with OrangeAndBlueMorality who wants the Keepers dead, but rather than fight, is forced to bring their organization down from the inside. [[spoiler:The Bailong Exams also examines the headspace of the kinds of villains who don't care about the common grunt getting killed, and whether the grunts' ingrained loyalty or their new experiences will win out.]]

* TheMole: D's main plan was to be one within the Rangers in order to get close enough to the Keepers to eliminate them. Yumeko reveals herself to D at the end of chapter 2 to be one against the Keepers as well, but for a different reason.

* OddlySmallOrganization: Green Battalion in a nutshell. Considering their primary function is hunting the Executives, it's unknown how big they were during their peak but presently there's only four members including Green Keeper. At the very least there were around half a dozen when Magatia was encountered in the ruins of an abandoned school but after the team sent after him were presumed dead and Green Keeper disappears for days to weeks at a time, there would only be ''one'' active Green Ranger at any given time. Other characters had commented that their low numbers were due to being wiped out in the past, though it's unknown if they were alluding to the encounter with Magatia.

* VillainWithGoodPublicity: Through the Dusters' perspective, the Dragon Keepers are the truly villainous people who gain respect of the public by taking advantage of their weakness and forcing the Dusters to continue playing their roles as the "villains" of the Dragon Keeper show. That said, like any good organization, there are members who are more self-serving and many who are dedicated to the surface cause of the Rangers.

** The series' English title is an obvious reference to the original ''Series/PowerRangers'' theme song.

* ShoutOut: When the final battle with Magatia begins, he dares D to come attack him while standing on top of a staircase. D moves to attack, but [[Manga/JoJosBizarreAdventureStardustCrusaders he's unable to get very far up the stairs because Magatia keeps moving him to his starting distance]]. He even taunts D the same way DIO does to Jean-Pierre Polnareff.

** Chapters 73 & 74 introduced a sort of reptilian monster that range in size from roughly a large alligator to significantly larger than a building. The Keepers believe they may be related to the Invaders as they had caught wind of the Executives attempting to revive the Giga-Invader Death Messiah but research from Yellow Battalion has been slow due to lack of living specimen.

* WeaksauceWeakness: The Divine Weapons, obtained and developed by the humans within a year into the invasion, are the only items capable of permanently killing the Invade. It allowed the Keepers to swiftly execute the Kaijin executives, while the remaining Dusters live in fear of being executed by them.

** Later in Chapter 52, D happens to come across someone getting arrested under suspicion of being an invader and managed to talk down the police into letting him go. D would later discover [[spoiler: he saved Green Ranger while he was in his civilian clothes.]]

* ActuallyIAmHim: Chapter 2 has D seeking out Red Keeper amongst a group of his apprentices. One of them, Shun Tokita, declares himself as the Keeper, only for Yumeko to prom[tly out him as just a third-rate apprentice (even though Shun insists it's only a matter of time).

e*** Chidori has access to Green Battalion's base, holds some very high level technology like Sloth Brain and Gluttony Way, and personally knows Hibiki Sakurama, despite only interacting with the Greens. You could justify it with the fact that he's giving out information to a top-class organization, but you could just as easily attribute it to [[spoiler:the fact that he's a top ranking Ranger, and thus would have a lot of access to that information and those tools]].

* ImmoralRealityShow: Thirteen years of Sunday battles have led the entire public to treat it as a BloodSport, constantly looking forward to the Keepers' slaughtering of the MonsterOfTheWeek every week while heavily jeering at the Dustrs.

** A concerned Mook F came down to Earth looking for D ''without donning a HumanDisguise'' just like the latter did[[note]]It could be justified as the following chapter explains different Dusters have different disguise specialties, and human disguises may not have been F's forte.[[/note]]. The public unrest he caused walking around soon caught the attention of Red Keeper, [[spoiler:who [[KilledOffForReal executes him]] for breaking the "No wandering on Earth during a non-Sunday" rule]].

* CompletelyDifferentTitle: The North American translation of the series evokes a different feel from the original Japanese, being a shout out to the ''Franchise/PowerRangers'' franchise. The French title is instead the LiteraryAllusionTitle ''[[GratuitousEnglish No Longer Rangers]]'', referencing the English translated title of Osamu Dazai's ''Literature/NoLongerHuman''.
