History Series / ChoushinseiFlashman

* ColorCodedCharacters: The codenames use each member's color as a head word and the team's prefix ("Flash") as the tail word, instead of the other way around.

* MythologyGag: The very name ''Chou[blank] [Blank]man'', without ''Sentai'' in the middle, echoes ''Series/ChoudenshiBioman'', as well as reusing the ''[[Series/HimitsuSentaiGoranger Goranger]]'' colors for the FiveManBand while sticking with TwoGirlsToATeam.

* {{Homage}}: The general theme of the show seems to be 1950s B-movies; The Mess base is a flying saucer, they [[AlienAbduction abduct and kidnap people]], and even the insectoid design of the Zolors could be an homage to movies like ''Film/{{Them}}'' (which involved attacking ants). As a counterpoint to this, the Flashmen's uniforms resemble fighter pilots; the Starcondor looks like a massive jet fighter, and the mecha it releases are two smaller jets and a tank.

* EverythingTryingToKillYou: [[spoiler:THe Anti-Flash Phenomenon. To wit: You touch fellow humans? You get electrocuted. You touch flowers? The flowers gas you. You try to drink? The water chokes you. You stand around in the open? The sun burns you.]]

* Lee Khefren: The EvilGenius, [[MonsterOfTheWeek Monster Maker]] and Ra Deus' right-hand man.

* ThemeNaming: Several of the Mess have Egyptian-inspired names, including Ra Deus, Lee Khefren, and Ley Nefer.

* MeaningfulName: Ra Deus. With a name like that, do you think [[AGodAmI he considers himself a god]]?

* EverythingTryingToKillYou: [[spoiler:Anti-Flash Phenomenon. To wit: You touch fellow humans? You get electrocuted. You touch flowers? The flowers gas you. You try to drink? The water chokes you. You stand around in the open? The sun burns you.]]

* ExpositoryThemeSong: Downplayed. The theme merely mentions that Earth is in danger and that the heroes have returned from space.

In 1966, the Reconstructive Experiment Empire Mess authorized the abduction of five kids for the purposes of their experiments. The benevolent beings from the Flash Galaxy saved the kids, and took each of them to a different planet of their solar system. Twenty years later, with the abilities they gained from the training on these planets, the now-grown kids return to Earth as Flashman, as they fight to protect their home planet from the menace of Mess while searching for their true parents.

* {{Homage}}: The interior of Round Base looks an awful lot like [[Series/DoctorWho the TARDIS]], down to the hexagonal console.
** The general theme of the villains seems to be a reference to 1950s B-movies, given their base is a flying saucer, they [[AlienAbduction abduct and kidnap people]], and even the insectoid design of the Zolors could be an homage to movies like ''Film/{{Them}}'' (which involved attacking ants).
** Perhaps as a counterpoint to this, the Flashmen's uniforms vaguely resemble fighter pilots; the Starcondor looks like a massive jet fighter, and the mecha it releases are two smaller jets and a tank.

* MakeMyMonsterGrow: Kuragen's reason for living. [[spoiler:Interestingly, it's a strange variety of LiquidAssets. It's like there's only so much "big" to go around, so ginormous scary-looking Kragen appears, makes the monster big... and then ''shrinks down to the size of a gerbil'' and has to scurry away from the battlefield as fast as his little tentacles can carry him. It's hilarious.]]

* LegoGenetics: This is how the Mess creates their monsters.

* {{Expy}}: The team's main robo, Flash King, is that to the previous sentai's robo, Change Robo, with the same color scheme and similar attacks.

** TeamPet: [=Mag=]; also their mentor.

* Dai ('''Green Flash'''): TheLancer, who is a [[TheBigGuy strongman]] with [[SuperStrength inhuman strength]].
* Bun ('''Blue Flash'''): KidAppealCharacter, who is a [[TheSmartGuy survival expert]] with [[SuperSpeed abnormal speed]].
* Sara ('''Yellow Flash'''): TheChick, who possesses a [[TheSmartGuy sharp, analytical mind]] [[SuperSenses for exposing enemy weakness]].
* Lou ('''Pink Flash'''): TheHeart, who is an ActionGirl with [[TheBigGuy real great strength]] and [[InASingleBound the best leaping skills]] of the team.

* FiveManBand: There are three [[TheSmartGuy Smart Guys]][[note]]Jin the scientist, Bun the survival expert, and Sara the analyzer.[[/note]] and two [[TheBigGuy Big Guys]][[note]]Dai the strongman and Lou the ActionGirl.[[/note]] on the team.

** TheLancer: Dai
** KidAppealCharacter: Bun
** TheChick: Sara
** TheHeart: Lou

The benevolent beings from the Flash Galaxy saved the kids, and took each of them to a different planet of their solar system. Twenty years later, with the abilities they gained from the training on these planets, the now-grown kids return to Earth as the Flashmen, To take revenge the Mess for abducting them as children and Trying to take over the earth, while also searching for the biological parents.

** [[spoiler:It was never stated that they couldn't return after recovering for a year or two, though. Thus, making it not as quite as bad.]]

* BizarreAlienBiology: Their years on the Flash planets have altered the Flashmen's genetic makeup, giving them superpowers but making it impossible for them to stay on Earth for more than a year.

* WhatHappenedToTheMouse: When the Flashmen head home to the Flash system at the end of the series, they only take the Star Condor back- both the Round Base (which brought them there) and the Flash Titan seem to have been completely forgotten about. Justified, though- they needed to leave Earth before they died, and either they or other denizens of the Flash system could always go back and retrieve the base and mecha later.
* YouCantGoHomeAgain: As the team finds out about halfway through when it turns out being away from the Flash system is killing them.

Twenty years later, with the abilities they gained from the training on these planets, the now-grown kids return to Earth to fight the Mess as the Flashmen. There's just one problem: since they've been away from Earth for so long, the planet's atmosphere has become deadly to them, so they can only stay for a year; otherwise, they die of the Anti-Flash Phenomenon.
