[[caption-width-right:325: The future has shone upon us with its glorious brilliance...]]

->''In a future yet to be, the third energy revolution is ushered in by the invention of the Shizuma Drive, and with it, mankind celebrates a new era of prosperity.''

->''But lurking in the shadows cast by the brilliance of our new found hope, two great powers clash!''

->''Big Fire; a secret organization bent on total world domination!''
->''"Hail, Big Fire! Allegiance or death!"''

->''But despair not! To defend us from the threat they pose, the International Police Organization's mighty Experts of Justice have been formed, comprised of members from around the globe! Fighting by their side is the greatest robot on the planet, Giant Robo, commanded solely by one young man: Daisaku Kusama!''

->''"Crush them! '''Go, Giant Robo!'''"''

''Giant Robo'' is one of the oldest franchises in Japanese comics. It first appeared as a manga by Mitsuteru Yokoyama that ran for nearly a year from 1967 and 1968. It was adapted into a live-action {{Toku}} series that same year, and the show gained a mild cult following when it was aired in the US as ''Johnny Sokko and His Flying Robot''.

But history be damned, when somebody mentions Giant Robo today, they're not thinking of either of those. They're thinking of ''Giant Robo The Animation: The Day The Earth Stood Still'', one of the greatest - or at least the most completely ''[[CrazyAwesome insane]]'' - works to come out of the anime industry in the last 20 years.

An ([[CrazyAwesome unholy]]) amalgamation of Wuxia, Superheroes, Creator/RichardWagner, [[HumongousMecha Mecha Anime]] and pure insanity, ''Giant Robo: The Day The Earth Stood Still'' is notable for being an early and rather impressive example of the MassiveMultiplayerCrossover, formed when director Yasuhiro ("''GGundam''") Imagawa was told that he couldn't use any of the supporting characters from the manga or TV versions of the ''Giant Robo'' story. Struck by inspiration, he instead decided to instead take characters from the rest of original creator Mitsuteru Yokoyama's work, including ''Babel II'', ''Sally the Witch'', ''Anime/RomanceOfTheThreeKingdoms'', ''Akakage'' and many others. To add to the effect he decided to draw them all in Yokoyama's classic 1960s style, along with a [[{{Zeerust}} retro-futuristic world]] set in an alternate 1920s populated by {{Ninja}}, ancient Chinese warriors, [[BadassInANiceSuit Sharp Suited Businessmen]] and {{Badass Longcoat}}s walking side by side.

Amazingly, [[CrazyEnoughToWork it works]].

Oh and don't pay any attention to the synopsis above, or let the art style and KidHero [[WhatDoYouMeanItsNotForKids fool you into thinking this is a kids' series]] in the vein of ''GIJoe'' or ''WesternAnimation/{{MASK}}''. ''Giant Robo'''s plot starts off slow and deceptively [[ClicheStorm cliché-ridden]], with a blatant MadScientist and McGuffin driving the first half of the plot, and then we get the WhamEpisode, rewriting the entire premise, beating the snot out of the good guys and resulting in several major characters getting KilledOffForReal. It's not the first, or even the most dramatic.

A new anime, ''GR: Giant Robo'', premiered in 2007 to celebrate the 40th anniversary of the original manga; however, it was not related to the OVA series, and many fans considered it a disappointment.

On the brighter side, Imagawa also scripted a new ''Giant Robo'' manga, "The Day The Earth Burned" that started publication in 2006. While this version is also an AlternateContinuity, it does act as a SpiritualSuccessor to the {{OVA}}s, with the same tone and many of the same characters. The original manga has also recently become available on most major manga websites.

See also: ''ShinMazinger'', another great SuperRobot series by Yasuhiro Imagawa. Like GiantRobo, it is a revival of a classic series and involves heavy crossover from the [[GoNagai original artist's]] entire body of work.

----
!!A series that LOVES its tropes, twisting them and playing them straight with the same vigor, the ''Giant Robo'' {{OVA}} features examples of:

* ActionBomb: [[spoiler:Silent Chuujo, apparently. As the Sphere floats towards the last Shizuma Drive bastion, there's Chuujo on a bluff. He loosens his tie and shirt, takes a few practice jabs, then ''flies up to '''punch''' the Sphere''.]] That dialogue in episode 2 makes far more sense when you know this.
* ActionGirl (Ginrei, Youshi)
* AllThereInTheManual: Since most of the MassiveMultiplayerCrossover characters lack in-universe backstories fans have ended up taking inspiration from the stories they originated from.
* AllYourBaseAreBelongToUs: The last act of the first OVA episode.
* ArcWords: "Beautiful Night!", "Can happiness be achieved without sacrifice?"
* AntiVillain: Hanzui the Evil Messiah, leader of the Magnificent Ten. Never actually does anything evil, proves extremely honourable and is a great deal nicer than most of the good guys.
* AnyoneCanDie: Murasame repeatedly, a few others as well. '''Alberto the Shockwave'''... [[spoiler:BWA HA HA HA HA HA - best twist ever.]]
* BadAss: A lot of the cast, but Alberto the Shockwave practically takes this to Memetic levels when, in ''VideoGame/SuperRobotWarsAlpha'', he battles one of the Angels from Anime/NeonGenesisEvangelion to a standstill whilst on foot.
* BadassInANiceSuit: Most notably Alberto and the Commander.
* BadassFingersnap: The Fabulous Fitzgerald, who can cut anything in half by snapping his fingers at it.
* BadassLongcoat: Murasame. The twist? It's [[RealMenWearPink BRIGHT PINK!]]
* BadassNormal: Daisaku. Sure, he owns "the world's strongest robot," but he's still the only normal human in the cast. Everyone else can fly, transform, use super strength and other bizarre powers.
* BigGuy: Tetsugyu and Youshi both fit this role. In a slight subversion Youshi is a woman, and certainly not a CuteBruiser either.
* BigDamnHeroes: Giant Robo's introduction, and several other examples.
* BilingualBonus: Tetsugyu's name roughly translates to "Iron Ox", one of the nicknames of Li Kui in Yokoyama's manga adaptation of ''Literature/WaterMargin''.
* BittersweetEnding
* BodyHorror: [[spoiler: Ginrei uses up her life power and her body disintegrates.]]
* BoisterousBruiser: Tetsugyu, Taisou, Youshi.
* BrokenPedestal: ''Zigzags'' with Vogler to one of his assistants. It goes back-and-forth at least 5 times, finally resulting in [[spoiler: subversion. Vogler really meant for the best for the world.]]
* TheBrute: In the BF there's Jujoji who has some devastating magic powers. The Fabulous Fitzgerald loves to carve up people with his snapping fingers.
* TheCallHasBadReception: Dr. Vogler had good intentions. Originally, his son had good intentions. The only problem was that by the time Dr. Vogler tells his son what needed to be done, he didn't have a very good vocabulary...
* CanonImmigrant: When Tetsujin #28 was remade in 2004, the Murasame Kenji that appears there isn't the original characterization - it's ''this'' one. He even calls himself "the immortal Murasame Kenji" just before [[spoiler:going down in a hail of bullets and encouraging Shotaro... then getting up and wiping off the ketchup.]] Additionally, Tetsujin uses Robo's '''growl''' rather than its original sound.
* CharacterDevelopment: Numerous but Tetsugyu has a great moment in the fifth OVA.
* CoolBigSis: Ginrei, Youshi.
* CoolOldGuy: One of Big Fire's Magnificent Ten is actually called Old Man Kawarazaki. His fellow Magnificent Ten colleague Shocking Alberto also has a lot of the traits, exchanging taunts with the early twenties BigBad over their respective ages.
* CultSoundtrack: The pompous Wagnerian soundtrack by Creator/MasamichiAmano is consistently mentioned in reviews as a major appeal of the OVA.
* DeathIsCheap: It is ''very'' cheap for Murasame Kenji, since he just revives despite several violent deaths, and since he can apparently do so in an area he couldn't get to corporeally, it's part of his ''strategy''. He even shoots himself in the head to drive home the point, noting that he "''can't'' die."
* EldritchAbomination: The ''Giant Sphere'' is an artificial example.
* EmpireWithADarkSecret: In ''Giant Robo: The Day The Earth Stood Still'', the Shizuma Drive, which provides clean, cheap energy, is completely recyclable and looks cool too was built upon a foundation of [[spoiler:the deaths of billions at the Tragedy of Bashtarle]]. A little LockedOutOfTheLoop as well, seeing as [[spoiler:Daisaku's the only character (except maybe Sunny) who doesn't know -- it's just that we only find out when he does]].
* EnemyMine: [[spoiler:Shocking Alberto in the Finale, as he considers the IPO a WorthyOpponent and the BigBad an annoying, grandstanding brat trying to steal Big Fire's thunder.]]
* EvilCounterpart: It seems that was going to be the case between Daisuke and Big Fire. One in charge of a giant robot, the other having three amazing guardians. Both very young. Though we don't know just how evil Big Fire really was.
* EvolvingCredits: "Earth, the terrifying world of our future! This is the Shizuma Drive, now broken and useless, [[TheEndOfTheWorldAsWeKnowIt the great energy revolution undone in just ten days!]]"
* TheDragon: Ko-Enshaku serves as an all purpose Dragon for Genya and Cho-Katsu Komei, neither of whom like to get their hands dirty if they can help it. Ivan to Alberto.
* EvilerThanThou: [[spoiler:Genya screws over apparent BigBad Shocking Alberto early on, and towards the end Cho-Katsu Komei does it to the rest of Magnificent Ten.]]
* EvilGenius: Most obviously Vogler [[spoiler: or so it seems.]] Old Man Kawarazaki seems to be an inventor. Zangetsu, if epileptic tress turned out to be true.
* {{Expy}}: Most characters of the OVA (who aren't from the original manga or anime) are Expys of Yokohama's other works, such as:
** Taiso (Dai Zong), Tetsugyu ("Iron Ox"/Li Kui), Youshi (Yang Zhi), Issei (Gongsun Shen), Koushin, Kaei (Hua Rong), Kaihou and Koshin (Xie Zhen and Xie Bao), Shutsu, the Fishermen Brothers (Ruan Xiaoer, Xiaowu, Xiaoqi), Hanzui (Fan Rui), Goyo, Kosonsho, and Jujoji all hail from ''Suikoden'' (''Literature/WaterMargin'').
** Cho-Katsu Komei is from ''Yokoyama Mitsuteru Sangokushi'' ("[=Records/=]RomanceOfTheThreeKingdoms"), better known as Zhuge Liang.
** Big Fire (Babel II/Koichi Yamano), Achilles (Lodem), Garuda (Ropross), and Neptune (Poseidon) were originally created for ''Babel II''. Also, Chujo the Silent, Cervantes, and Fitzgerald were modeled after various characters in the series.
** Likewise, Alberto the Impact was based on a character in Mars.
** Sunny the Magician is the original name of ''SallyTheWitch''.
** Red Mask bears similarities to ''Manga/KamenNoNinjaAkakage''.
** Kenji Murasame is a CanonImmigrant from [[{{Gigantor}} Tetsujin-28]], and Dr. Vogler and Dr. Montalblan hail from there as well.
** Ginrei is from ''Sononawa 101'' and ''Okami no Seiza''.
** Genya was originally from ''Iga no Kagemaru''.
* EyesAlwaysShut: Professor Go. And Doki about half the time. The other half has one eye open.
* FallingIntoTheCockpit: Daisaku was forced to take command of Giant Robo when his father and Murasame were mortally wounded trying to escape (and Murasame wouldn't heal in time.)
* FanFiction: A popular ''review and synopsis'' of the nonexistent GrandFinale fooled a lot of people. In its defense it would have indeed made a kickass episode.
* FiveBadBand: The five members assembled at the BF HQ and eventually [[spoiler: oppose Genya and Komei.]]
** TheBigBad: Hanzui who seems to be in charge unless Komei is given instructions from BF himself.
** TheDragon: Zangetsu.
** TheEvilGenius: Old Man Kawarazaki
** TheBrute: Jujoji
** TheDarkChick: Yuuki.
* GenreThrowBack: Daisaku's flashback on his origin plays a lot more like a typical giant robot show.
** Murasame: 'Daisaku! Use Robo's bazooka launcher!'
* GoodAllAlong: [[spoiler:'''Vogler.''']]
* HappilyMarried: Taiso and Youshi.
* HauntedTechnology: [[spoiler:Giant Robo appears to contain Professor Kusama's spirit/will,]] as hinted at throughout the series and seen in the last episode.
* HiddenDepths: Many characters like Daisaku, Tesugyu, Ginrei, and others. Really the entire OVA series itself as it first looks like a typical giant robot series.
* HumongousMecha: In the main OVA, Robo and the Big Fire robots are of the more old-school, "vaguely sentient yet highly suggestible and obedient" variety, while the Ginrei Robo and neo Tetsujin-28 are more modern, directly piloted versions.
* ICannotSelfTerminate: Murasame Kenji.
* ILoveNuclearPower: Somewhat averted - it doesn't get significant screen time, but pretty much everybody who's around is shocked and aghast when it is revealed that [[spoiler: Giant Robo is ''nuclear powered'']]. This is ultimately the reason [[spoiler: Robo is able to fight against Genya in the first place, because he isn't powered by Shizuma drives.]]
* ImplacableMan: The [[TheVoiceless silent]], [[TheFaceless armored]] Ko-Enshaku fills this role for the bad guys, enigmatically surviving everything thrown at him before turning up unharmed the next episode. The good guys on the other hand have Murasame, whose tendency to survive getting gaping holes blown through him becomes almost comical as the series goes on.
* InformedAbility: Tetsugyu is remarkably ineffectual in battle, despite frequent reference to his strength. We see him take down a swarm of Big Fire Mooks just fine, but that's about it. To be fair it's [[OvershadowedByAwesome more like the world around him is overpowered]] rather than him being weak.
* {{Irony}}: The BigBad's plot to destroy the world [[spoiler: technically succeeded, but wound up ''saving'' the world. Von Volger had tried to eliminate the new energy source because it was producing an undetectable poison gas that would wipe out all life on the planet after a certain point in time. The Eye of Volger was temporarily shutting down all of the energy cores in order to ''fix the poison gas problem.'']]
* IWantThemAlive: Happens in the last episode to Daisaku. [[spoiler: He manages to get away and make it to Robo though.]]
* KarmaHoudini: Cho-Katsu Komei gets away with everything, despite arrogantly declaring himself TheChessmaster and having none of the sympathetic motives of his fellow BigBad. As a result he generally has a very poor survival rate in fan continuations.
* KickTheDog: Murasame skips between this and CrowningMomentOfAwesome so quickly his teeth must rattle.
* KilledOffForReal: Played straight and averted, especially later on when everyone was expecting AnyoneCanDie. The anime still manages an impressive body count though, even with the odd couple of extremely unlikely NotQuiteDead.
* KineticWeaponsAreJustBetter: Cervantes points a gun at Daisaku, despite the fact he can generate enough heat from his hands to melt a thick steel door.
* KubrickStare: Part of Giant Robo's design.
* LineInTheSand -- Subverted. Our hero (recovering from a HeroicBSOD) never crosses the line, but the ''battle'' crosses it from the other direction. And the "line" is a crevice deeper than he is tall.
* LukeIAmYourFather: Ginrei is revealed to be [[spoiler: Von Vogler's daughter, and Genya's sister.]]
* TheKidWithTheRemoteControl: Subverted, slightly. Robo has its own will [[spoiler:apparently that of Dr. Kusama]] and usually only follows the general gist of the commands.
** Example from the last episode, at the Monster Sphere: "Shoot, Robo!" *Robo fires everything it has, plus one of its booster rockets*
* MadScientist: Dr Von Vogler [[spoiler:who eventually turns out to be a kindhearted and inspirational man who for PR reasons was blamed for the disaster one of the other scientists caused. After all, as far as anyone knew, he had [[NotQuiteDead died in said disaster]] and couldn't say any different!]]
* ManOfWealthAndTaste: Genya shows some traits of this trope.
* {{Mooks}}: Made an art form. The basic IPO mooks at one point spontaneously form a human pyramid in order to block an energy blast.
* MookMaker: To a degree, Doki, who commands a whole army of warriors instead of general BF mooks.
* MoreDakka: Giant Robo carries enough firepower to wipe a couple of cities off the map.
* MyGodWhatHaveIDone: [[spoiler:Genya, when he realizes that he horribly misunderstood his father's last wish and even killed his sister as a result.]]
* NewEraSpeech: Dr. Von Vogler's speech during the first flashback to the Tragedy of Bashtarlle (the one repeated as the ColdOpen of the second episode):
-->'''Dr. Fogler:''' The future has shone upon us with its glorious brilliance! The time to seize our destiny and conquer all our fears is ''now''! In ancient times, man rubbed sticks together to create fire. Then he slaughtered the whale and battled one another for oil. After that came [[ILoveNuclearPower the atomic age]]. In every chapter of our history, we danced with danger. But now it will be different. For the first time in our existence, we will be ''delivered from fear!!'' Finally, we will escape the prison of our delusions, and [[ArcWords the Beautiful Night]] ''will embrace us all''!
* NiceHat: Zangetsu, who has a five second role yet still manages to prove a fan favourite due to his very nice hat. And he might be [[EpilepticTrees the main character's father.]]
* NiceJobBreakingItHero: Averted! [[spoiler: Just barely, though.]] In the final episode you find out that [[spoiler: the Shizuma drives were actually creating a poisonous gas that would have destroyed all life on earth]] within days of the events that make up the series. The anti-drive [[spoiler: was actually created in order to eliminate this threat before it destroyed all known life.]] All of the "normal" drives [[spoiler: would have reactivated once all of the anti-drives had been activated at once, modified to correct the flaw.]] At the last minute,[[spoiler: despite the heroes' efforts]] all of the [[spoiler: anti-drives]] were activated, thus [[spoiler: saving the world.]]
* NiceJobFixingItVillain: [[spoiler: It turns out that when the three anti-drives are together they fixed the 2% problem or else they all would have exploded.]]
* {{Ninja}}: "Mask the Red" of Big Fire's Magnificent Ten.
* NoIndoorVoice: Everyone, especially as everything goes to hell. The dialogue of the final episode consists of nothing but EPIC SPEECH!
* NorioWakamoto: Taisou
* NotSoDifferent: Daisaku and Genya.
** And Daisaku and Tetsugyu [[spoiler: the latter saw Daisaku's expression when he damaged Robo's arm. The same feeling of pain as when Tesugyu slew his own father.]]
* OhCrap: Genya when [[spoiler:Alberto absorbs the heat energy from the sphere leaving it completely vulnerable to attack from Giant Robo.]] The look on his face as [[spoiler:Robo prepares to launch one of its rocket boosters as a missile]] is particularly priceless.
* {{Omake}}[=/=]{{Filler}}: The three ''Ginrei Special'' {{OVA}}s, ranging from a reasonably well-executed prequel Side Story to pure animated CrackFic, were created to maintain interest and raise funds during the main OVA's production delays.
** ClipShow: Most of the first Ginrei OVA.
** {{Crossdresser}}: Somehow, "Ginrei the Mighty" comes up with an excuse to have all the Experts wearing Ginrei's trademark Chinese mini-dress. Also, the first Ginrei OVA has Murasame [[LatexPerfection completely]] disguised as Ginrei for most of the episode.
** EvilTwin
** {{Fembot}}: The "Ginrei Robo".
** GoKartingWithBowser: The Experts and the BF organization drinking together in "Ginrei the Mighty".
** MoodWhiplash: The third episode is completely serious
** RefugeInAudacity: Ok, so the main series is this, but the omakes take this UpToEleven. We have things like Giant Robo nosebleeding gasoline at the sight of Ginrei naked, everyone dressing in Ginrei dresses, the below mentioned VictoriasSecretCompartment moment...
** ShoutOut: Ginrei Robo is a parody of Aphrodite-A from ''MazingerZ'', and Daisaku also gets to pilot an ersatz ''[[{{Gigantor}} Tetsujin 28-go]]'', revamped in the same way Giant Robo itself was in the OVA series.
*** Daisaku even wears Shotaro's signature plaid jacket rather than his own drab grey while piloting the redesigned Tetsujin 28.
** VictoriasSecretCompartment: Ginrei pulls a full-sized bazooka from her cleavage in "Iron-armed Ginrei / Ginrei the Mighty".
** WholesomeCrossdresser: ALL OF THE (male members of the) IPO in Episode 2. [[CrowningMomentOfFunny And it is hilarious.]]
* OnceMoreWithClarity: The story behind the Tragedy of Bashtarle changes multiple times over the course of the OVA.
* OverclockingAttack: this is what the Monster Sphere actually does to the Shizuma drives. Except the resulting energy can be harnessed...
* PapaWolf: Giant Robo has a Auto-Guard Circuit allowing it to activate and act of its own will when its controller's life (sensed through the wristwatch) is in danger. Robo breaks out of its maintenance dock and takes off for Daisaku (who doesn't seem to be aware of it) the first time, where it's noted that Robo was running at ''50 times'' its usual power.
** Subverted slightly, when Robo crashes into an unbreakable barrier - it ''can't control its output'' while in full-on PapaWolf mode, and runs the risk of melting down if allowed to continue for too long.
* PetTheDog: The scene in the 5th OVA where Genya comforts a delirious Daisaku [[spoiler: and then learning about his motivation for revenge.]] Also Ivan mentioning how his home was destroyed from [[spoiler: the Bashtorle disaster.]]
* ThePlan: Cho-Katsu Komei claims several times that he is pulling one of these off, though it is left ambiguous whether this is actually [[IMeantToDoThat true.]]
* RealMenWearPink: Murasame's overcoat and Hanzui's cape. Are you dumb enough to mock them?
* RefugeInAudacity
* RoofHopping: You know an organization is bad ass when all of its support staff / engineering mooks can roof hop onto a zeppelin to clear off before an attack. No really, Daisaku is the only normal human in the show.
* RuleOfCool: How else do you explain a mecha anime with supernatural kung-fu fighters and a Wagnerian soundtrack?
* SamusIsAGirl: Ginrei's introduction as the BadassLongcoat "[[MaskPower Iron Mask]]" during the prologue of the first episode.
* SequelHook: *Cries*
* ShaggyDogStory: [[spoiler: What it kind of boils down too when the three anti-drives are together at long last. A shame that the IPO were so good at their job. Even sadder that if Genya hadn't shot Ginrei then humanity would have been wiped out.]]
* {{Shotacon}}: It's... it's really, really, '''''really''''' easy to see subtext along these lines between Ginrei and Daisaku.
* ShoutOut: The subtitle of the OVA series is a shout out to the classic film ''Film/TheDayTheEarthStoodStill1951''.
** GR-2 sure seems like an antagonist Mazinger. Over sized lower jaw and rocket fists. One of the robos to appear several times in the opening appears to be an evil Getter 1.
* SuperRobot[=/=]RealRobot: The robots stray the line. They are considered powerful enough that, even with WorldOfBadass in play, no one wants to fight Robo one-on-one without a heavily stacked deck; on the other hand the organizational and maintenance issues they'd require is fleshed out and clearly just this side of 'impractical'. They're superweapons, and unless they're specifically built to take a hit the hand-to-hand fights don't last very long - take the complex snake-train robot being paralyzed after one hit in the first episode, for example.
* VideoGame/SuperRobotWars: [[VideoGame/SuperRobotWarsAlpha Alpha]] and [[VideoGame/SuperRobotWars64 64]]. Robo is considered strictly a SuperRobot in these continuities.
* TerminallyDependentSociety: All the world depends on the Shizuma Drive. When it is destroyed, everything else is. The only oil refinery left is at Shangai, and then it's destroyed too; there's some solar and wind power left, but not much. ''The world ends in ten days''.
* ThisCannotbe / BigNo: [[http://www.youtube.com/watch?v=00RjATZasNo See here]]
* UnexplainedRecovery: Numerous characters. On the villainous side [[spoiler: Alberto]]. Jujoji and Zangetsu sure acted dead in the sixth OVA but are fine in the seventh.
* VasquezAlwaysDies: Youshi.
* VictoriasSecretCompartment: Currently providing the page image.
* VillainousBreakdown: Genya, several times during the final episode. While he normally finds a way to salvage the situation the last one truly breaks him, and not without reason.
* VillainousRescue: '''Alberto the Shockwave.'''
* WorldOfHam: This series's universe seems to work purely ON HAM!!!
* WorthyOpponent: Big Fire considers the IPO to be one of these, and at least a few of the good guys feel the same. [[spoiler: Also '''Alberto the Shockwave's''' entire reason for faking his own death.]]
* WreckedWeapon: [[spoiler:Daisaku orders an extremely unwise attack on the Eye of Volger during the WhamEpisode, resulting in Giant Robo getting itself seriously damaged.]] Cue an OhCrap reaction from just about every single good guy on the field.
* XMarksTheHero: Tetsugyu
* YosukeAkimoto: As Alberto the Shockwave.

[[WMG: And the toku includes examples of...]]
* BraggingThemeTune
* BigBad: Emperor Guillotine
* BittersweetEnding: One that traumatized a number of childhoods in the 60s and 70s, both in America and Japan.
* CallingYourAttacks
* CompilationMovie: Several episodes of the American import were edited together into the movie "Voyage Into Space".
* MonsterOfTheWeek
* RocketPunch
* TransformationIsAFreeAction: Played ''painfully'' straight -- before he performs any attack, Giant Robo has to first go through a variety of stances, yet remains unmolested by the MonsterOfTheWeek. This is most evident during Robo's missile attack, which features StockFootage of him swinging his forearms side-to-side and up-and-down, then holding out his hands while missiles sprout from his fingertips... all while the monster waits for the routine to finish.

[[WMG: And the second manga "The Day the Earth Burned" includes examples of...]]

* BlackAndGrayMorality: The BF group are terrorists, the IPO are only a little nicer {{Smug Snake}}s. Daisaku and Fei Long's splinter group are the only nice people it seems.
* CallBack: A lot of robots that appeared in the opening finally get names or even return. The fifth robo that appeared in each opening is Gaia. And the black pointed one strolling through the city is Big Ox. And others.
* CompositeCharacter: Zangetsu is a combination of his old OVA design and Genya, mysterious new BF member. With a few more drops of PsychoForHire instead of stoicism.
* GoodIsNotNice: The IPO comes off much more antagonistic and gleeful compared to the OVA.
* {{Jerkass}}: Just about everyone who isn't Daisaku, Gen, Fei Long, and a few others.
* MsFanService: Gen's been reduced to being a fan service character. At least she's one of the few nice ones.
