Manga / Giant Robo

Go To
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... Okay, some people still think of Johnny Sokko and His Flying Robot, but usually only if they grew up in The '70s, watch over the air tv in the US or grew up in India and Brazil. Nowadays, they're thinking of Giant Robo The Animation: The Day The Earth Stood Still, one of the greatest - or at least the most completely insane - works to come out of the anime industry in the 20th century.


An (unholy) amalgamation of Wuxia, Superheroes, Richard Wagner, 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 Massive Multiplayer Crossover, formed when director Yasuhiro (Mobile Fighter G Gundam) 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, Romance of the Three Kingdoms, Akakage and many others. To add to the effect he decided to draw them all in Yokoyama's classic 1960s style, along with a retro-futuristic world populated by Ninja, ancient Chinese warriors, Sharp Suited Businessmen and Badass Longcoats walking side by side.


Amazingly, it works.

Oh and don't pay any attention to the synopsis above, or let the art style and Kid Hero fool you into thinking this is a kids' series in the vein of G.I. Joe or M.A.S.K.. Giant Robo's plot starts off slow and deceptively cliché-ridden, with a blatant Mad Scientist and McGuffin driving the first half of the plot, and then we get the Wham Episode, rewriting the entire premise, beating the snot out of the good guys and resulting in several major characters getting Killed Off for Real. 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 Alternate Continuity, it does act as a Spiritual Successor to the OVAs, 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: Shin Mazinger, another great Super Robot series by Yasuhiro Imagawa. Like Giant Robo, it is a revival of a classic series and involves heavy crossover from the original artist's entire body of work. Alternatively, the 2004 ''Tetsujin 28" anime, also directed by Imagawa based on another famous Yokoyama story with similar design aesthetics, a few bits of Retroactive Recognition (Kenji Murasame and the Black Ox most notably.

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

  • Action Bomb: 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.
  • Action Girl (Ginrei, Youshi)
  • Age Lift: Daisaku is 12 years old in the OVA like his tokusatsu counterpart instead of being around teenage years in the original manga
  • All There in the Manual: Since most of the Massive Multiplayer Crossover characters lack in-universe backstories fans have ended up taking inspiration from the stories they originated from.
  • All Your Base Are Belong to Us: The last act of the first OVA episode.
  • Arc Words: "Beautiful Night!", "Can happiness be achieved without sacrifice?"
  • Anachronic Order: This was the original intent of the OVA, as The Day the Earth Stood Still was the second to last arc of a seven part story. The next arc was going to show how Daisaku joined the Experts of Justice.
  • Anti-Villain: 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.
  • Anyone Can Die: Murasame repeatedly, a few others as well. Alberto the Shockwave... BWA HA HA HA HA HA - best twist ever.
  • Badass in a Nice Suit: Most notably Alberto and the Commander.
  • Badass Fingersnap: The Fabulous Fitzgerald, who can cut anything in half by snapping his fingers at it.
  • Badass Longcoat: Murasame. The twist? It's BRIGHT PINK!
  • Badass Normal: 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.
  • Battle Couple: Youshi and Taisou are married pair of government agents.
  • Big Guy: Tetsugyu and Youshi both fit this role. In a slight subversion Youshi is a woman, and certainly not a Cute Bruiser either.
  • Big Damn Heroes: Giant Robo's introduction, and several other examples.
  • Bilingual Bonus: Tetsugyu's name roughly translates to "Iron Ox", one of the nicknames of Li Kui in Yokoyama's manga adaptation of Water Margin.
  • Bittersweet Ending
  • Body Horror: Ginrei uses up her life power and her body disintegrates.
  • Boisterous Bruiser: Tetsugyu, Taisou, Youshi.
  • Broken Pedestal: Zigzags with Vogler to one of his assistants. It goes back-and-forth at least 5 times, finally resulting in subversion. Vogler really meant for the best for the world.
  • The Brute: In the BF there's Jujoji who has some devastating magic powers. The Fabulous Fitzgerald loves to carve up people with his snapping fingers.
  • The Call Has Bad Reception: 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...
  • The Cameo: Several Mecha from Mitsuteru Yokoyama's works make several apperances in the opening sequence such as GR-3, Black Ox, Monster and Gaia.
  • Canon Immigrant: 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 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.
  • Character Development: Numerous but Tetsugyu has a great moment in the fifth OVA.
  • Cool Big Sis: Ginrei, Youshi.
  • Cool Old Guy: One of Big Fire's Magnificent Ten is actually called Old Man Kawarazaki. His fellow Magnificent Ten colleague Shockwave Alberto also has a lot of the traits, exchanging taunts with the early twenties Big Bad over their respective ages.
  • Cult Soundtrack: The pompous Wagnerian soundtrack by Masamichi Amano is consistently mentioned in reviews as a major appeal of the OVA.
  • Death Is Cheap: 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."
  • Eldritch Abomination: The Giant Sphere is an artificial example.
  • Empire with a Dark Secret: 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 the deaths of billions at the Tragedy of Bashtarle. A little Locked Out of the Loop as well, seeing as Daisaku's the only character (except maybe Sunny) who doesn't know — it's just that we only find out when he does.
  • Enemy Mine: Shockwave Alberto in the Finale, as he considers the IPO a Worthy Opponent and the Big Bad an annoying, grandstanding brat trying to steal Big Fire's thunder.
  • Enigmatic Minion: Ko-Enshaku is an especially unsettling one.
  • Evil Counterpart: 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.
  • Evolving Credits: "Earth, the terrifying world of our future! This is the Shizuma Drive, now broken and useless, the great energy revolution undone in just ten days!"
  • The Dragon: 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.
  • Eviler Than Thou: Genya screws over apparent Big Bad Shockwave Alberto early on, and towards the end Cho-Katsu Komei does it to the rest of the Magnificent Ten.
  • Evil Genius: Most obviously Vogler 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), Kosonsho Issei (Gongsun Shen), Koushin (Huang Xin), Kaei (Hua Rong), Kaihou and Kaichin (Xie Bao and Xie Zhen), Shutsu (Zhou Tong), the Fishermen Brothers (Ruan Xiaoer, Xiaowu, Xiaoqi), Hanzui (Fan Rui), Richu (Li Zhong), Goyo (Wu Yong), Zangetsu (Han Tao) and Ko-Enshaku (Huyan Zhuo) all hail from Suikoden (Water Margin).
    • Cho-Katsu Komei (Zhuge Liang) and Jujojii (Zhang Rang) are from Yokoyama Mitsuteru Sangokushi ("Records/Romance of the Three Kingdoms").
    • Big Fire (Babel II/Koichi Yamano), Achilles (Lodem), Garuda (Ropross), and Neptune (Poseidon) were originally created for Babel II. Also, Chujo the Silent, Cervantes, Fitzgerald and even Daisaku's father, Dr. Kusama, were modeled after various characters in the series.
    • Likewise, Alberto the Impact, Ivan and Kawarazaki first appeared in Mars.
    • Sunny the Magician is the original name of Sally the Witch.
    • Red Mask was originally from Kamen no Ninja Akakage, and he is the main protagonist in that series.
    • Kenji Murasame is a Canon Immigrant from Tetsujin-28, and Dr. Vogler, Dr. Montalblan and Q Boss hail from there as well.
    • Ginrei is from Sononawa 101 and Okami no Seiza.
    • Genya and Yuuki were both originally from Iga no Kagemaru.
  • Eyes Always Shut: Professor Go. And Doki about half the time. The other half has one eye open.
  • Falling into the Cockpit: 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.)
  • Fan Fiction: A popular review and synopsis of the nonexistent Grand Finale fooled a lot of people. In its defense it would have indeed made a kickass episode.
  • Five-Man Band: The five members assembled at the BF HQ and eventually oppose Genya and Komei.
  • Gender Flip: Youshi is a female expy of Yang Zhi from the Water Margin and Yokoyama's Manga.
  • Genre Throw Back: Daisaku's flashback on his origin plays a lot more like a typical giant robot show.
    • Murasame: 'Daisaku! Use Robo's bazooka launcher!'
  • Good All Along: Vogler.
  • Happily Married: Taiso and Youshi.
  • Haunted Technology: Giant Robo appears to contain Professor Kusama's spirit/will, as hinted at throughout the series and seen in the last episode.
  • Hidden Depths: Many characters like Daisaku, Tesugyu, Ginrei, and others. Really the entire OVA series itself as it first looks like a typical giant robot series.
  • Humongous Mecha: 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.
  • I Cannot Self-Terminate: Murasame Kenji.
  • I Love Nuclear Power: 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 Giant Robo is nuclear powered. This is ultimately the reason Robo is able to fight against Genya in the first place, because he isn't powered by Shizuma drives.
  • Implacable Man: The silent, 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.
  • Informed Ability: 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 more like the world around him is overpowered rather than him being weak.
  • In Name Only: The OVA has next to nothing to do with Giant Robo or it's title character, rather it functions as an MCU-esque crossover for all of Mitsuteru Yokoyama's characters to interact in.
  • Irony: The Big Bad's plot to destroy the world 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.
  • I Want Them Alive: Happens in the last episode to Daisaku. He manages to get away and make it to Robo though.
  • Karma Houdini: Cho-Katsu Komei gets away with everything, despite arrogantly declaring himself The Chessmaster and having none of the sympathetic motives of his fellow Big Bad. As a result he generally has a very poor survival rate in fan continuations.
  • Kick the Dog: Murasame skips between this and Moment of Awesome so quickly his teeth must rattle.
  • Killed Off for Real: Played straight and averted, especially later on when everyone was expecting Anyone Can Die. The anime still manages an impressive body count though, even with the odd couple of extremely unlikely Not Quite Dead.
  • Kinetic Weapons Are Just Better: Cervantes points a gun at Daisaku, despite the fact he can generate enough heat from his hands to melt a thick steel door.
  • Kubrick Stare: Part of Giant Robo's design.
  • Line in the Sand — Subverted. Our hero (recovering from a Heroic BSoD) never crosses the line, but the battle crosses it from the other direction. And the "line" is a crevice deeper than he is tall.
  • Luke, I Am Your Father: Ginrei is revealed to be Von Vogler's daughter, and Genya's sister.
  • The Kid with the Remote Control: Subverted, slightly. Robo has its own will 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*
  • Mad Scientist: Dr Von Vogler 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 died in said disaster and couldn't say any different!
  • Man of Wealth and Taste: 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.
  • Mook Maker: To a degree, Doki, who commands a whole army of warriors instead of general BF mooks.
  • More Dakka: Giant Robo carries enough firepower to wipe a couple of cities off the map.
  • Motherhood Is Superior: Averted. Fatherhood drives a lot of the characters. The end credits even dedicate the film to fathers and sons.
  • My God, What Have I Done?: Genya, when he realizes that he horribly misunderstood his father's last wish and even killed his sister as a result.
  • New Era Speech: Dr. Von Vogler's speech during the first flashback to the Tragedy of Bashtarle (the one repeated as the Cold Open 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 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 the Beautiful Night will embrace us all!
  • Nice Hat: 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 the main character's father.
  • Nice Job Breaking It, Hero!: Averted! Just barely, though. In the final episode you find out that 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 was actually created in order to eliminate this threat before it destroyed all known life. All of the "normal" drives would have reactivated once all of the anti-drives had been activated at once, modified to correct the flaw. At the last minute, despite the heroes' efforts all of the anti-drives were activated, thus saving the world.
  • Nice Job Fixing It, Villain!: 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.
  • No Indoor Voice: Everyone, especially as everything goes to hell. The dialogue of the final episode consists of nothing but EPIC SPEECH!
  • Not So Different: Daisaku and Genya.
    • And Daisaku and Tetsugyu the latter saw Daisaku's expression when he damaged Robo's arm. The same feeling of pain as when Tesugyu slew his own father.
  • Oh, Crap!: Genya when Alberto absorbs the heat energy from the sphere leaving it completely vulnerable to attack from Giant Robo. The look on his face as Robo prepares to launch one of its rocket boosters as a missile is particularly priceless.
  • Omake/Filler: The three Ginrei Special OVAs, ranging from a reasonably well-executed prequel Side Story to pure animated Crack Fic, were created to maintain interest and raise funds during the main OVA's production delays.
    • Clip Show: 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 completely disguised as Ginrei for most of the episode.
    • Evil Twin : Named "Electric Shock Rosa" by Alberto
    • Fembot: The "Ginrei Robo".
    • Go-Karting with Bowser: The Experts and the BF organization drinking together in "Ginrei the Mighty".
    • Mood Whiplash: The third episode is completely serious
    • Refuge in Audacity: Ok, so the main series is this, but the omakes take this Up to Eleven. We have things like Giant Robo nosebleeding gasoline at the sight of Ginrei naked, everyone dressing in Ginrei dresses, the below mentioned Victoria's Secret Compartment moment, Daisaku claiming to be 29 years old and divorced...
    • Shout-Out: Ginrei Robo is a parody of Aphrodite-A from Mazinger Z, and Daisaku also gets to pilot an ersatz 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.
    • Victoria's Secret Compartment: Ginrei pulls a full-sized bazooka from her cleavage in "Iron-armed Ginrei / Ginrei the Mighty".
    • Wholesome Crossdresser: ALL OF THE (male members of the) IPO in Episode 2. And it is hilarious.
  • Once More, with Clarity!: The story behind the Tragedy of Bashtarle changes multiple times over the course of the OVA.
  • Overclocking Attack: this is what the Monster Sphere actually does to the Shizuma drives. Except the resulting energy can be harnessed...
  • Papa Wolf: 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 Papa Wolf mode, and runs the risk of melting down if allowed to continue for too long.
  • Pet the Dog: The scene in the 5th OVA where Genya comforts a delirious Daisaku and then learning about his motivation for revenge. Also Ivan mentioning how his home was destroyed from the Bashtarle disaster.
  • The Plan: Cho-Katsu Komei claims several times that he is pulling one of these off, though it is left ambiguous whether this is actually true.
  • Putting on the Reich: The "Big Fire" villainous organization wants to conquer the world using superweapons and has even copied the Hitler salute (the straight-arm salute with the right hand and transforming "Heil Hitler" into "Hail, Big Fire! Allegiance or death!").
  • Real Men Wear Pink: Murasame's overcoat and Hanzui's cape. Are you dumb enough to mock them?
  • Refuge in Audacity
  • Roof Hopping: 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.
  • Rule of Cool: How else do you explain a mecha anime with supernatural kung-fu fighters and a Wagnerian soundtrack?
  • Samus Is a Girl: Ginrei's introduction as the Badass Longcoat "Iron Mask" during the prologue of the first episode.
  • Sequel Hook: *Cries*
  • "Shaggy Dog" Story: 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.
  • Shout-Out: The subtitle of the OVA series is a shout out to the classic film The Day the Earth Stood Still (1951).
    • 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.
  • Super Robot/Real Robot: The robots straddle the line. They are considered powerful enough that, even with World of Badass 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.
  • Terminally Dependent Society: 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.
  • This Cannot Be!/Big "NO!": See here
  • Unexplained Recovery: Numerous characters. On the villainous side Alberto. Jujoji and Zangetsu sure acted dead in the sixth OVA but are fine in the seventh.
  • Vasquez Always Dies: Youshi.
  • Victoria's Secret Compartment: Currently providing the page image.
  • Villainous Breakdown: 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.
  • Villainous Rescue: Alberto the Shockwave.
  • Who Wears Short Shorts?: Daisaku wears these—with a suit jacket. (It's a Japanese school uniform.)
  • World of Ham: This series's universe seems to work purely ON HAM!!!
  • Worthy Opponent: Big Fire considers the IPO to be one of these, and at least a few of the good guys feel the same. Also Alberto the Shockwave's entire reason for faking his own death.
  • Wrecked Weapon: Daisaku orders an extremely unwise attack on the Eye of Volger during the Wham Episode, resulting in Giant Robo getting itself seriously damaged. Cue an Oh, Crap! reaction from just about every single good guy on the field.
  • X Marks the Hero: Tetsugyu
  • Yosuke Akimoto: As Alberto the Shockwave.
  • Zettai Ryouiki: Daisaku has a Grade D.

And the 1967 manga includes examples of..

  • Land, Sea, Sky: The GR units were made with this mindset.
    • GR-1 was built for mainly land based attacks.
    • GR-2 was designed to traverse in the ocean.
    • GR-3 was created for air attacks.
  • Mistaken for Spies: The beginning of the manga has Daisaku captured by Big Fire agents in Taiwan after mistaking him for a sleeper agent trying to destroy their factory producing GR-1.
  • No Ending / Sequel Hook: The manga ends with Daisaku and GR-1 destroying Big Fire's undersea base drowning everyone inside it and the two rising up from the depths of the surface but Big Fire is still on the loose and the narrator assuring the audience Daisaku and Robo will fight until Big Fire is defeated for good.

And the toku includes examples of...

  • Adapted Out: GR-3, a flying robot capable of high-speed aerodynamics, never made an appearance in the series though toy company Marmit made a GR-3 vinyl in the style of the live action series robots.
  • Adult Fear: Daisaku/Johnny and Mari (the two child agents of Unicorn) weld guns, get captured all the while the villians try to put an inch of their lives. The absolute crowner is in the Grand Finale where Daisaku/Johnny Is shot by a sniper and everyone thinks he is dead even though he was fine due to wearing "the iron vest" but still. The fact that Johnny wasn't allowed to tell his family about his status as UNICORN agent makes it worse. What happens if he got killed on duty and his parents would never find out he died?
  • Artistic License – Gun Safety: In episode 12, Mari gets the attention of Johnny and Jerry at Unicorn's shooting range by firing her sidearm over their heads at the target from the staircase behind them.
  • Bragging Theme Tune
  • Big Bad: Emperor Guillotine
  • Bittersweet Ending: One that traumatized a number of childhoods in the 60s and 70s, both in America and Japan. Giant Robo defeats Guillotine, but his body is "a mass of atomic energy" that would destroy the Earth when he dies.To prevent this, Giant Robot grapples the Emperor and flies him into space to explode harmlessly against an asteroid much to Johnny's and the other heroes horror.
  • Blob Monster: Hydrazona, the acidic bacteria monster sent in by Big Fire in episode 24. It destroys part of Unicorn's headquarters and gruesomely kills several Unicorn redshirts onscreen.
  • Calling Your Attacks: The Ur-Example in the Mecha Genre. Daisaku/Johnny would call GR-1's attacks via shouting it in the watch.
  • Compilation Movie: Several episodes of the American import were edited together into the movie "Voyage Into Space".
  • Cool Shades: Big Fire wears them. Nameless redshirts wear traditional sunglasses, while Spider wears a pair of aviators.
  • Eyepatch of Power: Harlequin(Black Diamond in the Japanese version). It ends up being how Unicorn identifies him as a double agent in his debut episode.
  • Heroic Sacrifice: Giant Robo does this in the Grand Finale
  • Intergenerational Friendship: Daisaku Kusama (12) and his fellow Unicorn agent Juro Minami(Jerry Mano in the English dub) (20's).
  • Large Ham: All of the villains, but especially Emperor Guillotine and Commander Spider.
  • Make My Monster Grow: Quite possibly the Ur-Example for the tokusatsu genre, several kaiju in the show including Drakulon and Emperor Guillotine himself were able to change their size from human size monsters to giant size beasts to fight off Giant Robo.
  • Monster of the Week
  • Our Monsters Are Weird: And how. Giant eyeballs with legs, Robot hands, Robot Jawbones Giant rolling balls that shoot out rockets from it's tips, and that's just only a few of the weird things Big Fire uses...
  • Putting on the Reich: Big Fire's human agents wear uniforms that resemble Wehrmacht uniforms. Their human commander Spider wears an officer's hat that resembles an SS officer's hat.
  • Reality Warper: Dr. Eingali(Dr. Germa in the Japanese version), a strange green alien from the "4th Dimension of Evil". He manages to create an exact duplicate of Johnny that gains control of Giant Robo for a short time.
  • Reluctant Mad Scientist: Dr. Lucius Guardian, a scientist who was kidnapped by Big Fire and was forced to help build Giant Robo for destructive purposes. Fortunately, He rebelled and gave the wrist watch controller to Daisaku so that Giant Robo won't be used for evil.
  • Rocket Punch: GR-2 used it against Giant Robo in Episode 16. And you thought Mazinger Z did it first!
  • Rubber-Forehead Aliens: Dr. Botanus(Dr. Over in the Japanese version), a recurring villain introduced in episode three, is a portrayed as an actor coated in silver paint with a prosthetic brow on his head. He also has the same clawed hands as Emperor Guillotine.
    • Fangar(Red Cobra in the Japanese version) features a more traditional giant prosthetic rubber forehead.
  • Sacrificial Lamb: In the first episode, Dr. Lucius Guardian gave his life in order to let Daisaku and Juro escape. Shortly before Dr. Guardian was gunned down, he set off a bomb in order to destroy a part of Big Fire's base.
  • Transformation Is a Free Action: Played painfully straight — before he performs any attack, Giant Robo has to first go through a variety of stances, yet remains unmolested by the Monster of the Week. This is most evident during Robo's missile attack, which features Stock Footage 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.

And the second manga The Day the Earth Burned includes examples of...

  • Adaptational Villainy: The IPO comes off much more antagonistic and gleeful compared to the OVA.
  • Black and Gray Morality: The BF group are terrorists, the IPO are only a little nicer Smug Snakes. Daisaku and Fei Long's splinter group are the only nice people it seems.
  • Call-Back: 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.
  • Composite Character: Zangetsu is a combination of his old OVA design and Genya, mysterious new BF member. With a few more drops of Psycho for Hire instead of stoicism.
  • Jerkass: Just about everyone who isn't Daisaku, Gen, Fei Long, and a few others.
  • Left Hanging: The manga had a sequel/finale manga "The Siege Of Babel" that ran for 6 volumes...until that also ended on a cliffhanger. GREAT.
