[[caption-width-right:350:[[StuffBlowingUp There's a lot of explosions in this one...]]What, you thought Dyna didn't ''mean'' anything?]]

->''Bakuhatsu![[note]]Explode![[/note]] Kagaku Sentai! Dynaman!''

''Kagaku Sentai Dynaman'' ([[ScienceHero Science Squadron]] Dynaman) is the seventh ''Franchise/SuperSentai'', which aired from 1983 to 1984. It was the first to utilize spandex suits. The TitleThemeTune was sung by [=MoJo=] for the third time in the series. From episode 10 onwards, the franchise's timeslot would be cut down from 30 minutes to 25 minutes due to TV Asahi wanting to expand the timeslot for a news program. This would remain until the franchise was given a Sunday morning timeslot beginning with [[Series/DenjiSentaiMegaranger Megaranger]].

It begins when Hokuto Dan, a kendo master and an inventor, received an invitation from the famous Dr. Yumeno. On the way, he witnesses a strange creature attacking innocent people. He attempts to help; along the way, he encounters other inventors that also received similar invitations: fencer Rei Tachibana, swimmer Yousuke Shima, cowboy Kousaku Nangou and later ninja Ryuu Hoshikawa. While they are able to fend off the strange creatures, the creatures overwhelm them and throw them out to sea. However, they survive and make it to the place where Dr. Yumeno resided... a Kindergarten.

The Kindergarten soon turns out to be the Yumeno Invention Center in disguise. Yumeno called them because he had sensed the rise of the Jashinka Empire, the forces that attacked the five on the way to the invention center. The only force that can stop them is the ''Science Squadron Dynaman'', and these five are the chosen warriors! Like [[Series/DaiSentaiGoggleFive their predecessors]], they don't have second thoughts to the prospect of becoming allies of justice and immediately agree to Dr. Yumeno's offer. Thus, the Dynamen's battle against the Jashinka Empire begins!

What this Sentai's best known for is actually being the first to reach American airwaves. [[OlderThanTheyThink Before there was]] ''Series/MightyMorphinPowerRangers'', this show received a GagDub by the Americans (including future Series/KidsInTheHall!) on the Creator/USANetwork. It was very silly, [[NarmCharm but fun in its own way]]. As episodes were included in the compilation series Special Delivery, it's also the first to air on Nickelodeon, beating Samurai by over 20 years. This version can be streamed on the platform Night Flight Plus.

Creator/ToruOhira, who has been narrating the series up until this time, would leave from narrating the series after this installment, until he came back narrating ''Series/KyoryuSentaiZyuranger''.

!!Recurring Super Sentai tropes:

* AchillesHeel: In episode 23, the slug monster is immune to salt being thrown on most of it's body, bragging he's immune. Too bad for it, it's eyes were still super sensitive to salt.
* AllYourColorsCombined: The Super Dynamite and New Super Dynamite, where the Dynamen merge into a ball of energy to zap monsters.
* ByThePowerOfGreyskull: "Dynaman!"; or, their individual names.
* CallingYourAttacks: The Dynamen does a lot of this, particularly when summoning their arsenal or giant robot.
* ColorCharacter: Another "[team prefix] [English color]" Sentai.
* CoolAirship: The Dai Jupiter.
* CoolBike: Dyna Red's Dyna Falcon bike
* CoolCar: The Dyna Machine for the rest of the team.
* CoolHelmet: The Dynaman helmets are distinguished simply by the shape of their visors.
* CustomUniform: Dyna Red, Blue, and Pink have yellow trim on their suits. Respectively, Dyna Black's suit has red trim instead while Dyna Yellow's suit has black trim. There are [[Series/KousokuSentaiTurboranger three]] [[Series/ChoujinSentaiJetman other]] [[Series/NinjaSentaiKakuranger Yellow Rangers]] that have black trim, in place of yellow, on their suits, [[spoiler: not counting [[Series/KaizokuSentaiGokaiger Luka Millfy's]] version of [[Series/HyakujuuSentaiGaoranger Gao Yellow]].]]
* EvilWillFail: [[spoiler:Megiddo falling victim to the FantasticCasteSystem and becoming the Dark Knight to defeat his father, along with Zenobia's scheme to surpass Aton, end up killing most of the Jashinka, with the Dynamen finishing the job by killing Megiddo and Chimera when the dust settles.]]
* FinishingMove: Super Dynamite!
* HomeBase: This was the Yumeno Invention Center, which also doubled as a Kindergarten. This made Zenobia's debut a KickTheDog moment for her.
* HumongousMecha: Three mecha components again, only this time Red was the only who got an individual mecha, while the rest were shared between two members each.
** CombiningMecha: Dyna Mach (Red) + Dyna Mobile (Black and Blue) + Dyna Garry (Yellow and Pink) = Dyna Robo
* InTheNameOfTheMoon: Ala the [[Anime/SailorMoon trope namer]], one of the heroes (usually [=DynaRed=]) tells off the MonsterOfTheWeek for its evil actions before calling out their names and "Explode! Science Squadron Dynaman!".
* LawOfChromaticSuperiority:
* MonstersOfTheWeek: The ''Shinkajū'' (Evo-Beasts). Later replaced with Mecha-Shinka robots from Episode 34 and onward.
** MakeMyMonsterGrow: The Evo-Beasts grow whenever the Dynamen had them on the ropes[[note]]always after the Super Dynamite.[[/note]]; the [=MechaShinka=] monsters are enlarged by General Kar's Grand Gizmo device.
* {{Mook}}s: Tail Soldiers
* TheMovie: The ''Dynaman'' film was later shown during the course of the actual series as Episode 32, although chronologically it takes place before Chimera joins Jashinka in Episode 8.
* OnTheNextEpisodeOfCatchPhrase:
* RegularCaller:
* RobotBuddy: The Kendo Robot.
* TheSmurfettePrinciple: Dyna Pink, who strangely doesn't wear a skirt or leotard on her costume like other Sentai heroines.
* SupervillainLair: Grand Gizmo
* ThemeMusicPowerUp: The Opening Theme was always present from posing to FinishingMove.
* TransformationTrinket: Dyna Brace.
* VillainsActHeroesReact: As is the norm for ''Super Sentai'', we generally have Jashinka sending out a MOTW with an EvilPlan OnceAnEpisode, with our heroes then arriving on the scene to stop them.
%%** SwissArmyWeapon: The Dyna Rods.[[note]]Gun and [[CarryABigStick Baton]] Modes.[[/note]]
%%** Hokuto: [[BifurcatedWeapon Dy]][[DualWielding na]] [[CoolSword Swords]][[note]]This codifies the HeroesPreferSwords for Super Sentai reds.[[/note]]
%%** Ryuu: [[BattleBoomerang Cross Cutter]] and [[PoweredArmor Battle Tector]].
%%** Yosuke: [[ImprobableWeaponUser Blue Frisbees]]
%%** Kousaku: [[EpicFlail Chain Crushers]]
%%** Rei: [[CoolSword Rose Saber]] and [[LuckilyMyShieldWillProtectMe Flower Shield]].

!!Tropes specific to Kagaku Sentai Dynaman:

* ActionGirl: While most Sentai heroines previous to Dynaman can hold her own, Rei is the first to be more focused in fighting and more capable on holding on her own.
* AllYourBaseAreBelongToUs: Subverted, [[spoiler: Zenobia debuts by discovering the Dynaman's headquarters and swiftly attacking it, but the attack didn't destroy the base. Unfortunately, the base's location still ends up leaked so the Dynaman had to abandon it.]]
* AppliedPhlebotinum: The Retro Gene, the genetic means to increase cells. [[spoiler: Also a DeadlyUpgrade.]]
* AntiHero: The Dark Knight is heavily Type V, while he has no obligation with the Dynaman, he still occasionally attacks the Jashinka Empire on his own accord. [[spoiler:Until Zenobia and Aton falls and he reveals that he is actually Megiddo in disguise. Then he drops the 'Hero' part and once again becomes a thorough villain.]]
* BerserkButton: When Jashinka begins kidnapping and brainwashing mothers to look after their eggs sets Dan off, since he never knew his own mother.
* BruceLeeClone: Yusuke acts like this in the fight in episode 5.
* CatFight: Unlike the [[Series/DaiSentaiGoggleFive previous show]], Chimera doesn't just [[EvilCounterpart share]] [[TheHeart Rei's]] abilities and such... they come to direct blows at times. Hell, during the final battle, they specifically fight one-on-one while the male Dynamen fought Megiddo.
* ChainedHeat: Dan and the Mammoth monster are handcuffed together in episode 33.
* DarkActionGirl: Princess Chimera and later [[spoiler:General Zenobia]]
* DubNameChange: Pretty much the only names that weren't changed in the parody were the team name and their ranger designations.
** Hokuto -> Wooshi, their leader
** Ryu -> Huba, able to leap tall trees
** Yousuke -> Franky, human outboard motor
** Kousaku -> Cowboy, slow-thinking weapons expert
** Rei -> Slojin, their main squeeze
* DivingKick: The Dyna Kick. A team attack that's used about OnceAnEpisode.
* ElementalPowers: The Dynamen's side arms fire a blast of a certain element.
%%** PlayingWithFire: Hokuto's Red Fire.
%%** LightEmUp: Ryuu's Black Star Flash.
%%** MakingASplash: Yosuke's Blue Water Whirlpool.
%%** ShockAndAwe: Kousaku's Yellow Lightning Fall.
* EnemyCivilWar: [[spoiler: Dark Knight wages war against Aton when he emerges.]]
* EnemyMine: A version of this is in episode 33. Mammoth Evolution is so out of control the villains have to try and stop him. This is in part because the monster smashed through a bacteria research facility and got a virus attached to him. Between the inability to tell friend from foe and the fact he was giving a disease that could wipe out all the tail soldiers as well as just plain stomping a lot of tail soldiers flat, the villains try and take him down as well as the Dynamen. But then Dan is handcuffed to the mammoth, and the villains are more then happy to take out two problems at once...
* EvilutionaryBiologist: The Jashinka. Their name literally translates to ''Evilution''.
* {{Fanservice}}: At one point, Rei and Chimera had a fight which end up slowly stripping them to nothing but bikinis. (they transform to stop).
** Chimera's bath scene at the start of episode 29 AND Rei wearing the stolen Chimera's cloth.
* FantasticCasteSystem: The Jashinka are ranked by the number of tails they have; for reference, the {{mooks}} have one, while Aton has nine and desires ten.
* GadgetWatches: The changer bracelets are actually called that in the GagDub.
--> We could use gadgets!
--> And watches too!
* GagDub: Aired as ''Dynaman'' in the U.S. in 1988, as a part of the Creator/USANetwork's overnight ''Night Flight'' block (and was later rerun on Creator/{{Nickelodeon}}); this was the first exposure to ''Franchise/SuperSentai'' in the U.S. (outside Hawaii and parts of California).
* HighlyVisibleNinja: Ryuu. He's comical and sometimes very loud and [[LargeHam hammy]] (like when he introduced himself). And his element is [[LightEmUp LIGHT]].
* HoistByHisOwnPetard: In episode 34, the Monster Of The Week uses movement seeking missiles to attack people. Because the Super Dynamite finisher won't work on the lobster monster, so Dynaman make sure the missile gets launched at them, then they all jump on the lobster and shake around, the missile comes to them, they jump out out of the way, the missile manages to blow up the monster who sent it out to start with.
* HollywoodVoodoo: In episode 29.
* InsertSong: The GagDub was very fond of playing these over action scenes. Lots of Music/BillyIdol and Huey Louis among others.
* {{Irony}}: Rei wants to develop a device to communicate with animals... [[WhyDidItHaveToBeSnakes yet she's terrified of CATS]].
* TheJuggernaut: Mammoth Shinka, so much of a Juggernaut that the Jashinka Empire ''sealed'' him, and when released, even Megiddo cannot control him.
* JumpedAtTheCall: In a way. Like [[Series/DaiSentaiGoggleFive the previous team]], Hokuto, Hoshikawa, Shima, Nangou and Rei has no qualms of becoming allies of justice after exposition, but since being a Dynaman doubles as resuming their duties as scientists... it's not exactly 'old-life abandoning'.
* KarmicDeath: Zenobia [[spoiler:gets the Retro Gene to get a tenth tail, only to fall victim to its side-effects.]]
* LadyInRed: Princess Chimera
* LadyOfWar: Rei is a pretty handy with a rapier and... well did we mention her flowery motif?
* LastNameBasis: Same like [[Series/DaiSentaiGoggleFive the last season]], although there were slips. The boys are usually called on their surnames, "Dan, Hoshikawa, Shima, and Nango". The sole girl is sometimes referred as "Rei", or like the rest, her surname "Tachibana".
* LighterAndSofter: While the show is still pretty serious it's around this time that the franchise started lightening up on civilian casualties. They still happen occasionally, but compared to previous shows often having an average of 1 to 2 civilian deaths per episode Dynaman and shows after it are pretty light and typically the victims of the week no matter how they are affected by the monsters are usually restored by the end.
* MagicalSecurityCam: Dr. Yumeno's computer can capture footage from unlikely places.
* ManEatingPlant: A Butterfly MonsterOfTheWeek created one which [[spoiler:cut Gira and Geel's careers ''very'' short.]]
* MasterOfIllusion: The fox monster in episode 24 should count. Ryu's ninja skills also which turned out to be a match for the fox.
* MidSeasonUpgrade: The [=JaShinka=] upgrade to the [=MechaShinka=] cyborg monsters, resulting in the Dynamen upgrading to the New Super Dynamite.
* MotiveDecay: The [=Jashinka=] ''quickly'' go from wanting to evolve humanity into their own kind to wanting to KillAllHumans.
* NiceJobBreakingItHero: Episode 29 had Ryuu accidentally steal Chimera's clothes. In retaliation, Chimera had a MonsterOfTheWeek put a voodoo curse on anyone wearing RED (same color as her clothes). And it expands to other colors too...
* PublicDomainSoundtrack: "A Night On Bald Mountain" by Mussorgsky and "Les Toreadaors" from "Carmen" are used in episode 28.
* RoadSignReversal: Done to trick Hokuto into a trap in episode 9.
* ScienceHero: Literally. Before they became a sentai team, all of them are inventors who are experts in the fields of science.
* ShakingTheRump: #8, the debut of Princess Chimera, offers a close-up shot of her shaking her booty as she flaunts her tail in her short skirt.
* SquashedFlat: The Mammoth monster in episode 33 is so out of control he caused this to happen to a group of Tail Soldier Mooks!
* TheStarscream: [[spoiler:Zenobia]]
* StuffBlowingUp: '''So very much of it!'''
** The intro alone features at least 35 explosions - including 20 of them in the first ''16 seconds.''
* TakenForGranite: The Monster Of The Week does this to Kosauku and some random civilians in episode 4.
** And a Medusa head statue turns many people to stone in episode 46.
* TheUnfought: [[spoiler:[[BigBad Aton]] is never fought by the Dynaman]].
* WellDoneSonGuy: A villainous example: [[spoiler: Aton, slain by Megiddo, names his son as successor with his dying breath.]]
