->''On one fateful day, five children from Earth were kidnapped and sent to the far reaches of outer space. Twenty years later...''

''Chōshinsei Flashman'' (''Supernova Flashman'') is the tenth Franchise/SuperSentai show, airing from 1986 to 1987. The TitleThemeTune was sung by Taku Kitahara.

In 1966, the Reconstructive Experiment Empire Mess authorized the abduction of five kids for the purposes of their experiments, however, 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.

!!'''Recurring''' Super Sentai tropes:

* AllYourColorsCombined / {{BFG}}: The Rolling Vulcan. One of the more insane [=BFGs=] in Sentai history- a cannon with four smaller cannons mounted to it that revolves and fired a spectrumatic beam.
* ByThePowerOfGrayskull: "''Prism Flash!''"[[note]]Also the name of their TransformationTrinket[[/note]]
* CallingYourAttacks
* ColorCharacter: The codenames use each member's color as a head word — as in ''[[Series/ChoudenshiBioman Bioman]]'' — and the team's prefix ("Flash") as the tail word, instead of the other way around.
* ColorCodedCharacters: The Flashmen of course.
* CoolAirship: The Star Condor
* CoolBike: The Flash Hawk bikes, one for each member.
* FiveManBand:
** TheLeader: Jin
** TheLancer: Bun
** [[TheSmartGuy The Smart Girl]]: Sara
** TheBigGuy: Dai
** TheHeart: Lou
** TeamPet: [=Mag=]; also their mentor/babysitter.
* {{Expy}}: The team's main robo, Flash King, is that to the [[Series/DengekiSentaiChangeman previous sentai's robo]], Change Robo, with the same color scheme and similar attacks.
* EyeCatch: This season does away with drawn eyecatches and replaces them with live-action ones. The Flashman and Flash King pose in front of the Earth, before and after the commercial break, respectively.
* HomeBase: The Round Base, a large building that can go into space.
* HumongousMecha: The first Sentai team to have a second giant robot. The first robot was the usual combining mech, while second was of the transforming kind.
** CombiningMecha: Tank Command (Red) + Jet Delta (Green and Yellow) + Jet Seeker (Blue and Pink) = Flash King
** TransformingMecha: The Flash Titan truck, which transforms into the support robot Titan Boy, which can then combine with its trailer to form the Great Titan.
* LawOfChromaticSuperiority: Jin gets control of the largest of the Flash Mecha, the Tank Command and mans the team Finishers, as well as being the big bro of the team.
* 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. In the finale, Kuragen is combined with the remains of Ra Deus to create a three-legged monstrosity known as the Demos.]]
* MonsterOfTheWeek: The ''Jūsenshi'' or Beast Warriors, creatures created by Lee Keflen's genetic synthesizer from the genes of Earth's animals ([[spoiler:the final series of monsters were created by combining the genes of Ra Deus himself with those of his underlings]]).
* {{Mooks}}: The insectoid Zolors, complete with acid webbing.
* TheMovie: Two, although the second was a CompilationMovie of Titan Boy's intro arc (ep. 15-18).
* OnTheNextEpisodeOfCatchPhrase: "Prism Flash! ''Chōshinsei Flashman!''"
* RegularCaller:
* RobotBuddy: [=Mag=].
* SupervillainLair: Reconstructive Experiment Base Labor, a sort-of flying saucer.
* ThemeMusicPowerUp:
* TransformationTrinket: See ByThePowerOfGrayskull
* TransformationNameAnnouncement
* TwoGirlsToATeam: The third Sentai team with two girls and the second with a Yellow and Pink duo.
* VillainsActHeroesReact: As is the norm for ''Super Sentai'', we generally have Mess sending out a MOTW with an EvilPlan OnceAnEpisode, with our heroes then arriving on the scene to stop them.
* WeaponBasedCharacterization
** BifurcatedWeapon: The Prism Shooters.[[note]]Splits from a gun into a [[CoolSword sword]] and [[LuckilyMyShieldWillProtectMe shield]].[[/note]]
** HandCannon: The "Vul" guns, one for each member and named after each of their respective color.
** Jin: [[CoolSword Prism Seiken]][[note]]''Prism Holy Sword''[[/note]]
** Dai: [[PowerFist Prism Kaiser]]
** Bun: [[BarrierWarrior Prism Ball]] and [[FlechetteStorm Star Darts]].
** Sara: [[DualWielding Prism]] [[CarryABigStick Batons]] and [[ImprobableWeaponUser Shocking Beads]].
** Lou: [[ArmedLegs Prism Boots]] and [[ImprobableWeaponUser Shocking Hearts]].

!!Tropes specific to Choushinsei Flashman:

* AmnesiaMissedASpot: The Tokimura's receive a partial memory wipe from Mess but it didn't completely take as they remember enough to figure out that their son had been taken by aliens 20 years prior [[spoiler:which is almost correct but Tokimura's amnesia removed one critical detail. It wasn't a son they lost but a DAUGHTER, Sara.]]
* AntAssault: The Zolors, given they appear to be humanoid ants.
* BirthdayEpisode: Episode 38 takes place on Jin's birthday, or more accurately, the day they celebrate as his birthday because the rangers don't know when they were really born.
* BizarreAlienBiology: Their years on the Flash planets have altered the Flashmen's genetic makeup, giving them superpowers but [[spoiler: making it impossible for them to stay on Earth for more than a year.]]
** Also, Lou has the ability to float in the air, and Bun can climb the sides of walls.
* BittersweetEnding: [[spoiler:Sara finds her real family, she and the other Flashmen destroy the bad guys, but they have to leave the Earth for the sake of their lives.]]
** [[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. Sara even swears she'll return someday.]]
* TheBoxingEpisode: Episode 27.
%% * CompetitiveBalance
%% ** JackOfAllStats: Jin
%% ** MightyGlacier: Dai
%% ** FragileSpeedster: Bun
%% ** LightningBruiser: Sara
%% ** GlassCannon: Lou
* DeadAllAlong: Episode 20 introduces Sumire, a teenage girl with a strong connection to Dai, making him think they could be siblings. [[spoiler: 17 episodes later, it’s revealed that Sumire died 8 years ago, with her appearing as a ghost to Dai thanks to finding a fragment of the Green Star where he grew up]].
* DealWithTheDevil: In their final confrontation Keflen [[spoiler:tries to cut a deal with the Flashman to let him leave in peace with his Genetic Synthesizer to continue his experiments away from the Earth and in exchange he'll use it to repair their genetics making them full Earthlings again and no longer be affected by the Anti-Flash Phenomenon allowing them to live on Earth forever and find and return to their missing families. They consider it, especially since Sara had just found her family but then Sara herself makes the call to destroy it as Mess has done too much harm for her to ever allow it.]]
* DontThinkFeel: How the team deals with Dai's sight being turned upside-down in Episode 4, despite Mag wanting him to undergo TrainingFromHell on a handstand.
* DubNameChange: Dai is called "Dan" and Bun is called "Go" in Brazil.
* 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.]]
* EvilWillFail: Keflen and Cowler despise each other over differing views on using Beast Warriors. After one offense too many, Cowler goes third-party, eventually [[spoiler:exposing Ra Deus's true nature, which in turn amplifies Keflen's god complex as he takes over Mess and gets two final Beast Warriors out of Deus, while Cowler and the remaining generals die out before Keflen finally bites it.]]
* ExpositoryThemeSong: Downplayed; the theme merely mentions that Earth is in danger and that the heroes have returned from space.
* FishOutOfTemporalWater: Every single member of the Flashmen.
* FountainOfYouth: Dai ends up a child because of a monster attack in episode 41.
* FusionDance: Several of the Deus Beast Warriors are created by parts of Ra Deus being fused with other characters. [[spoiler:The Alien Hunters are all also fused into a singular being to create a Deus Beast Warrior. The Demoss, the final one, is a fusion of Deus's remains and Kuragen.]]
* HeelFaceTurn: Baraki used to work for Mess, until his life was saved by Titan the Hero.
* HeterosexualLifePartners: Cowler & Gardan.
* {{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); they also have walking tripod machines a la ''Film/TheWarOfTheWorlds''. 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.
* InconsistentSpelling: The names of the members of Mess are highly inconsistent from source to source. For example, is it Ley Nefer, Ney Nefel or Leh Näfel? The latter spelling is officially used by [=RangerWiki=], but the other two are also used without any attempts at correction.
* LegoGenetics: This is how the Mess creates their monsters. [[spoiler: It's also how Ra Deus even started -- he's a ''living mass of genetic material''.]]
* MeaningfulName: Ra Deus. With a name like that, [[SarcasmMode do you think]] [[AGodAmI he considers himself a god]]?
** The name "Tokimura" means "time village". Dr. Tokimura is a time machine inventor.
* MidSeasonUpgrade: Episodes 15-18 have a mini-arc where Flash King's blown to pieces and they get a second mecha. In 29, Flashman's powers start to weaken, so they upgrade their prisms to power up their attacks, which coincides with the Mes officers getting super modes to be more of a threat.
* 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, the RobotBuddy and having the codenames use the color as a head word rather than the tail.
* NonStandardCharacterDesign: Compared to most Sentai, the Flashman helmet design is unique; instead of simple helmet shells, they're designed presumably to mimic helmets worn by pilots; they also have, in a first for the franchise, visors that can open and close (though this was never used outside the henshin sequences).
** Following the example of the previous [[Series/ChoudenshiBioman two]] [[Series/DengekiSentaiChangeman series]], the female Rangers suit have LeotardOfPower design rather than skirt or MinidressOfPower like most other female Rangers. This design won't be seen again in ''Super Sentai'' until the appearance of [[Series/KikaiSentaiZenkaiger Zenkai Magine]], more than three decades later.
* OddlyNamedSequel2ElectricBoogaloo: The fourth and final Sentai not to use the word "Sentai" in its title.
* OnlyOneName: The first Sentai team to have its members lack surnames, [[spoiler:though we find that Sara's last name is Tokimura]].
* OnlyTheLeadsGetADownerEnding: [[spoiler:The Flashmen defeat the Mess Empire for good, but almost succumb to the Anti-Flash Phenomenon and have to leave Earth as a result.]]
* [[PrecursorHeroes Precursor Hero]]: the Hero Titan, the one who the Flash Aliens based the Flashman technology on.
* PowerCrystal: Their prisms, which are contained in their Prism Flash braces. One episode had them get damaged, then repaired, leading to their MidSeasonUpgrade. They also have small prisms in their helmets.
* PowerIncontinence: The first stage of the Anti-Flash Phenomenon is the rangers' powers mysteriously giving out on them in the middle of fights.
* PublicDomainSoundtrack: "Ride of the Valkyries" plays during Dr. Tokimura's time-jumps in Episodes 8-9.
* RaceAgainstTheClock: The final episode. The Flashmen have only 10 hours left to destroy what's left of Mess [[spoiler:and get the hell off of Earth before they die of the Anti-Flash Phenomenon.]] Every break in the action comes with a chyron saying how long they have left.
* RainbowMotif: Especially noticeable when they fire the Rolling Vulcan, which is a giant rainbow death beam.
* RedHerring: Detailed above under DeadAllAlong.
* RedOniBlueOni: Dai is the hot-blooded red while Jin is the cooler blue. Rather ironic given Jin is the Red and Dai is Green, which is made from mixing blue and yellow.
* ShoutOut: The interior of Round Base looks an awful lot like [[Series/DoctorWho the TARDIS]], down to the hexagonal console.
* TheSpeechless: Ley Galus and the other monsters can only growl.
* SpellMyNameWithAThe: All Mess monsters have names preceded with that article. [[spoiler:Including the other members of Mess once Keflen starts using Ra Deus' genes to tamper with theirs and turn them into [=MotWs=].]]
* SuperMode: Wanda and Nefel get them later in the show, whereas Flashman power up but keep the same uniforms as before.
* TakingYouWithMe: [[spoiler:The Flash King is crippled when one of a pair of monsters blew up on it after being dealt the death blow; this necessitated the need to get Great Titan. [[UnexplainedRecovery It does get better a few episodes later.]]]]
* ThemeNaming: Several of the Mess have Egyptian-inspired names, including Ra Deus, Lee Keflen, and Ley Nefer.
* TieInNovel: ''My Heart's Flashman''[[note]]Waga Kokoro no Flashman[[/note]], written by Azusa Nakajima.
* TimeStop: Ley Wanda later gains this ability.
* TomboyAndGirlyGirl: The strong but compassionate Lou and sensible and thoughtful Sara.
* TouchedByVorlons: The Flashmen gained their superhuman powers as a result of growing up in the Flash System.
* TheVoiceless: The Alien Hunters, with the obvious exception of Sir Cowler.
* WeCanRuleTogether: Invoked by Lee Keflen at the very last episode to the Flashmen. Much to everyone's surprise, it's Sara who's the first to [[ShutUpHannibal call shenanigans on it]].
* WhatHappenedToTheMouse: [[spoiler: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.]]
* [[spoiler:YouCantGoHomeAgain: As the team finds out about halfway through when it turns out being away from the Flash system is killing them.]]
* [[spoiler:YourDaysAreNumbered: Toward the final episodes, as the Anti-Flash Phenomenon harms our heroes further and further. Episode 46 is even called "Only 20 Days to Live!!".]]
