A ShowWithinAShow to ''Anime/MartianSuccessorNadesico'', ''Gekiganger 3'' is an [[AffectionateParody affectionate]] [[SatireParodyPastiche pastiche]] of Super Robot anime of the 1970s and 1980s. An {{OVA}} was released in 1998 which compiled all the ''Gekiganger 3'' clips seen in ''Nadesico'' in chronological order and included a ShortAnimeMovie.

The [[ThePrecursors ancient Super-Paleolithic people]] predicted that the alien Kyo'akk empire would invade the planet and [[FlingALightIntoTheFuture left behind plans]] for a Super Robot, Gekiganger III, to stop them. Professor Kokubunji builds it, and HotBlooded pilots Ken Tenku, Joe Umitsubame, and Akira Daichi take it into battle against the mecha monsters of Prince Akara and his overlord, Emperor Hyperion. Midway through the series, Joe is killed and the Gekiganger III is destroyed only to be replaced with Gekiganger V and new pilot Tetsuya Ryuuzaki.

Sounds exactly like every other SuperRobot series out there, right? [[ClicheStorm Good, that's the point]].

The OVA movie (with the FramingDevice of the ''Nadesico'' cast seeing the movie in a theater) features the return of the Super-Paleolithic people, who attack both the humans and the Kyo'akks in an attempt to reclaim the world. Akara must temporarily join forces with the Gekiganger team to stop them.

Title completeness aside, not to be confused with ''Series/JukenSentaiGekiranger''.

%%* AliensAndMonsters
* AliensStealCable: The Kyo'akks research Earth culture by watching anime.
* AllThereInTheManual We only see short clips of the series in ''Nadesico'', but there's plenty of supplemental material included with the merchandise that tells more of the ''Gekiganger'' story.
* AmericansAreCowboys: Cowboy Johnny and the Texas Robo are from America.
* AmnesiacDissonance: Aquamarine, an enemy who gets amnesia in a crash and falls in love with Ken.
* BackFromTheDead: [[spoiler:Joe Umitsubame of course.]]
%%* ByThePowerOfGreyskull
* CallingYourAttacks: It's a SuperRobot show, what do you expect? '''GEKIGAN SWORD!'''
* ChestBlaster: '''GEKIGAN FIRE!''' Only on Gekiganger V curiously enough.
%%* CombiningMecha
* DaysOfFuturePast: Despite being a perfect imitation of a 1970s super robot show, it was supposedly created in the 2090s.
* DeflectorShields: Both Akara's robot and the Kokubunji lab have them, the former of which was, oddly enough, based on the Nadesico's Distortion Field. A strange result of the ClipShow episode causing a ''recursive'' case of ShowWithinAShow.
* {{Eagleland}} Cowboy Johnny and his Texas Robo are from America.
* {{Expy}}: The main cast are all Expies of the cast of both ''Manga/GetterRobo'' and ''Anime/VoltesV''.
* EyeBeams: Gekiganger's eyes can shoot '''GEKIGAN BEAM!'''.
* FaceHeelTurn: Nanako's brother Rokuro becomes a villain.
* FamousLastWords: Subverted. Joe's first death had him saying "I'm sorry, Nanako-san... I couldn't take you to the ocean..." This, in the Nadesico-verse, became very iconic that [[spoiler:Gai Daigoji specifically said that when he was KilledOffForReal]]. But then subverted that in the sequel, Ken turns out NotQuiteDead.
%%* FinishingMove:
%%** Gekiganger 3 has '''Nekketsu Giri''' and '''Gekigan Flare'''.
%%** UmiGanger has '''Gekigan Shock'''.
%%** Rikuganger has '''Musashi no Jigoku Meguri'''.
%%** Gekiganger V has '''Gekigan Spin''', '''Chou-Nekketsu Giri''', and CombinationAttack with Gekiganger 3, '''Double Gekigan Flare'''.
%%** Dragonganger[[note]]unused design seen in Nadesico[[/note]] has '''Dragon Breast'''.
* FullyAbsorbedFinale: Not exactly a "finale", but the OVA actually does advance the story of ''Nadesico'' briefly, by showing that [[spoiler:Akito and Yurika are going to get married]].
%%* HeroicSacrifice: Joe, Sapphire, and Aquamarine.
%%* HotBlooded: '''CHOU-NEKKETSU-GIRI!'''
%%* HumongousMecha: Affectionately pastiched.
%%* InescapableNet: '''GEKIGAN NETTO!'''
%%* LostTechnology
%%* MadScientistsBeautifulDaughter: Nanako Kokubunji.
* MeaningfulName: Ken Tenkuu's name when said in the proper Japanese order of Family -> Given, is rendered as Tenkuu Ken, which was the name of the weapon used to execute Anime/VoltesV's FinishingMove.
%%* MechaExpansionPack: Spaceganger and Dragonganger
%%* MechaMooks
* MonsterOfTheWeek: Presumably... we don't see ''Gekiganger'' every week.
%%* MidSeasonUpgrade: Gekiganger V
* {{Narm}}: Intentional, as part of the AffectionateParody. Even InUniverse some people comment on how ridiculously melodramatic the plots can get.
* OffModel: Again, intentional, though there's surprisingly little of it... the biggest offenders are probably the fight scene between Ken and Joe, though that's more of an ArtShift, and Joe's mouth when he's telling Ken to use Gekigan Flare before he dies.
%%* PowerTrio: See the FMB above and subtract Junpei and Nanako.
* RecapEpisode: The Gekiganger team watches the Recap Episode of ''Nadesico''. The OVA also starts with a recap of sorts- a compilation of several ''Gekiganger'' clips that had previously been seen in ''Nadesico''.
%%* {{Retraux}}
%%* RocketPunch: '''GEKIGAN PUNCH!'''
* SayMyName: "JOOOOOEEEEEEE!!!" is the most famous, but there's also "SAPPHAIAAAAAAA!", "AQUAMARIIIIIINE!" and even, in the movie, "KEEEEN!"
* ShoutOut: If it's not foreshadowing for the plot of ''Nadesico'', it's probably a ShoutOut to an old-school anime: see below.
* ShowWithinAShow: ''Anime/MartianSuccessorNadesico''. It runs both ways. [[MST3KMantra Don't try to figure out how that works.]]
* StayInTheKitchen: Done only slightly less obviously than usual in the movie- Nanako wants to replace Ken in the Gekiga Jet but Joe tells her she should stay with him instead. Despite this, the [[spoiler:Jovians]] in ''Nadesico'' who based their culture on ''Gekiganger'' follow this as a philosophy.
%%* SuperSpeed: '''GEKIGAN VISION!'''
* ThemeNaming: The family names of the main pilots have to do with where their vehicles run. Also, Aquamarine and Sapphire are both named after jewels and both fall in love with a hero.
%%* TitleThemeTune
%%* TransformingMecha

!!Anime series that receive a ShoutOut in ''Gekiganger 3'' include:

* Anime/CombattlerV and Anime/VoltesV: The villains are similar to those of these series; Gekiga Jet, Marine, Tank = Combattler V's Battle Jet, Marine, Tank; Gekiganger V's name comes from Combattler V and upon its appearance performs the same pose; Gekigan Sword = Voltes V's Tenkuu Ken, which also gave its name to Gekiganger's hero. And "Let's Gekiga In" is a play on Voltes V's "Let's Volt In".
* Anime/{{Daitarn 3}}: the logo for the show is very similar in the design for the "3"
* Manga/{{Devilman}}: Gekigan Cutter = Devil Cutter.
* Manga/GetterRobo: the three-machine/three-robot system; the character archetypes of the pilots and supporters; Gekigan Vision = Getter Vision; one of Rikuganger's finishing moves is named for Musashi; the death and replacement of a main character (though not the same archetype); the final pose in Gekiganger's transformation sequence is the same as that of ''Getter Robo G''; Cowboy Johnny/Texas Robo = Jack King/Texas Mack.
* ''Anime/MazingerZ'': Gekigan Fire, Gekigan Punch, Gekigan Beam = Breast Fire, Rocket Punch, Koshiryoku / Photo-Atomic Beam; "Gekiganger Dies In Flames!" = "Kouji Kabuto Dies In Lava!"; The movie has a similar plot to one of the Mazinger Z movies and begins with a similar opening sequence. The Gekigan Sword is also deployed from the side of the knee, just like the Mazinger Blades. Joe's BigDamnHeroes moment at the end of the series is similar to Tetsuya and Great Mazinger's introduction in the Mazinger Z movie as well.
** Anime/GreatMazinger and {{Anime/Daimos}}: The SixthRanger Tetsuya Ryuuzaki is named after the main characters of Anime/GreatMazinger ('''Tetsuya''' Tsurugi) and {{Anime/Daimos}} (Kazuya '''Ryuuzaki''').
* Anime/ScienceNinjaTeamGatchaman: TheHero and TheLancer are Ken and Joe, respectively. [[spoiler: And Joe dies and returns...]]
