In the forefront, Tetsuya and Jun. In the background, Great Mazinger, Venus A... and Boss Borot.
"All battles I have fought so far… I have fought them to prove the world that I exist!"
Great Mazinger (グレートマジンガー, Gurēto Majingā) is the second entry of the Mazinger series by manga artist Go Nagai and a direct continuation of the successful Mazinger Z. It was aired on Japanese television in 1974, immediately following the end of the first series, and it ran for 56 episodes.Several millennia ago, a powerful civilization named Mykene thrived in the Greek island of Bardos. To defend their island from invaders, they employed metallic giantsthat blasted tongues of fire from their chests. However, an earthquake destroyed their island and the Mykene disappeared. For a long while it was believed they perished right then, but it was false. In reality they were forced to seek shelter underground, and a lot of them grafted their heads into powerful mechanical bodies to survive. However they longed to return to the surface again and getting the sunlight, fresh air, and unpolluted water back.Many centuries later, Dr. Hell and Dr. Kabuto conducted research on Bardos and through different means both of them reached the conclusion that their civilization was still alive. Dr. Hell decided on allying himself with one them (which would be a bad move). Dr. Kabuto suspected the Mykene were preparing to return to the surface and take it back from humans and he decided to start taking precautions.When his son and his daughter-in-law were mortally injured in a laboratory accident that went awry, he turned his son into a cyborg to keep him alive and revealed to him his plans and his fears. Kenzo Kabuto agreed to work secretly to prevent the Mykene invasion.After the ending of Mazinger Z, Mazinger Z was easily destroyed by the Mykene Battle Beasts. Kouji and Sayaka went to study in America, leaving the defense of Earth on the hands of Tetsuya Tsurugi and Jun Hono, two combat-pro orphans who are slightly Darker and Edgier compared to Kouji and Sayaka. Piloting Great Mazinger -an upgrade to Mazinger Z, built by Kenzo, Kouji’s Not Quite Dead father, by improving upon his father’s plans- and Venus A, Tetsuya and Jun go to battle the Mykene Empire, led by the Emperor of Darkness, and eventually Tetsuya becomes the Worthy Opponent of The Dragon, The Great General of Darkness.Considered Darker and Edgier than its predecessor, Great Mazinger was less successful and less popular among fans. It was followed by the next, and final, entry of the trilogy, UFO Robo Grendizer. There were several crossovers among it and other Go Nagai series, such as Getter Robo and UFO Robo Grendizer, and the two main characters reappeared in Mazinkaiser.A Character Sheet is now in construction.
This series features examples of:
A Head at Each End: Several Mykene War Beasts had a head at each end (an occurrence happened more often than you would think since ALL Mykene War Beasts had several heads: one of them was the Humongous Mecha's head and the other -or others- belonging to the human warrior fused with the mecha). This trope was used for first time in the Mazinger universe in the Mazinger Z vs Great General of Darkness feature.
An Axe to Grind: Some War Beasts also were axe-wielders. General Juuma -one of the Co-Dragons of Ankoku Daishogun- wielded one in the Mazinger Z vs Great General of Darkness (and nearly skewers Mazinger's head -and Kouji- with it). In the proper series, Garalya (in the episode 2) was the first War Beast in using an axe (a huge double-headed axe with no handle).
Abusive Parents - Parents as People: Kenzo Kabuto. He almost died cause a laboratory experiment gone wrong, but his father saved his life. However both of them thought it would be better not telling Kouji and Shiro -Kenzo's sons- he had survived. For YEARS Kouji and Shiro grew up mostly alone, thinking their father died alongside their mother while, though he did have the pretty decent excuse that he was building a Humongous Mecha to defend humankind. When this was revealed Kouji was too glad to hold a grudge, but Shiro took a long while until he could forgive him. Also, Kenzo had no troubles slapping Tetsuya when he thought his adoptive son was crossing the line. All of it finally bit everyone's butts at the end of the series.
Ace Pilot: Tetsuya, considering the fact that he is a well trained combat pro, this is pretty logical.
One of the Super Robot Wars manga takes this Up to Eleven. He is such a good pilot that he can handles an army of Mycenean beast and its high class general with only a little help of Venus in a short time. In fact, he is so much of an ace that Egret Fehu considered Tetsuya to be an Ultimate Lifeform, being described as the soldier that humanity sought to achieve and, as a result used as a reference for creating the Machinery Children. SANGER ZONVOLT sees the result of Great fighting with an expression that implies fear on his face.
The best part of it? While the Egret Fehu part is debatable, all of this(him defending the South Atalia base with Venus) is canon. And this is a story set before the event of Alpha Gaiden.
Action-Hogging Opening: The openings of the trilogy feature more action -featuring the titular HumongousMechas tearing their way through an army of enemies-, and a better animation than an average episode of their series -especially of Grendizer-.
Advanced Ancient Acropolis: The Mykene inhabited the Greek island of Bardos. Their technologic level was miles ahead of any other culture of the same time, and the rest of the world would need millennia to catch up. However, one earthquake shook their island and destroyed their cities, and they were forced to seek shelter underground. They founded another civilization Beneath the Earth, but on the surface the only remainder left of their presence were abandoned, decaying ruins, and old legends about the Humongous Mecha they used to defend their land.
Air Jousting: Great Mazinger was able to fly, and the Avian Host was comprised of bird-alike Animal Mecha specialised in this kind of battles. Aerial duels were constant, the first happening in the first episode and the last of them in the last episode.
Airborne Aircraft Carrier: Mykeros and later Demonika, Mykene Empire's flying fortresses. All of them were flying fortresses with formidable attack powress and capability to store several War Beasts.
In Great Mazinger, the final battle is won when Mazinger, Great Mazinger, Aphrodite A and Venus A combine their strongest attacks to bring Cool Airship Demonika down.
In UFO Robo Grendizer, Mazinger-Z, Great Mazinger and Grendizer combined all of their attacks in one manga scene to destroy a Vegan starship. And in one of the movies, Grendizer and Great Mazinger combined their Chest Blaster attacks to destroy a Saucer Beast.
In the first episode of Mazinkaiser, Mazinger-Z and Great Mazinger used their Chest Blaster weapons in combination to melt a Mechanical Beast to slag.
Great Mazinger and Getter Robo have also combined their attacks in several movies.
The Super Robot Wars games have exploited this. When several of the Go Nagai mechas show up in the same game, they are given combination attacks. It is usually called Final Dynamic Special, and it is always impressive: .
Always Chaotic Evil: The Mykene play with this trope. The Warrior Monsters are Humongous Mecha with the head of a Mykene soldier implanted in the giant mechanical body. Since the soldiers are indoctrinated to attack and wipe out anything non-related to the Mykene civilization, the trope is justified. On the other hand, the commanders of the army display different personalities and even honorable qualities (specially Ankoku Daishogun), and even though they are not portrayed like good, they are not portrayed like proud of being evil, but like a proud race of warriors want to return to the surface world after being forced to living underground for millennia.
Animal Mecha: The Mykene Empire army was split in seven armies. Five out of those seven armies were named after the animals their mechas resembled: mammals, birds, reptiles, fishes and insects.
Armed Legs: Great Mazinger has two attacks based around this, the Knee Impulse Kick (a retractable knee spike) and the Backspin Kick (a cutting blade in the lower leg).
Arrogant Kung-Fu Guy : Tetsuya, mostly a Jerkass on daily basis, who always make sure that you know that he is a Combat Pro, both by his attitude, and his performance at battle.
In the Great Mazinger vs Getter Robo feature, Tetsuya tried all Great Mazinger's weapons against an Eldritch Abomination. Neither did work, and the monster ripped off his mecha's arms and melted one leg. What Tetsuya did? Trying headbutting it.
In one of the first episodes, Kenzo Kabuto had to actually threaten him with -to Tetsuya- a Fate Worse than Death: "Return to the Fortress NOW or else you will be out of Great Mazinger... permanently".
In his climatic Sword Fight with The Dragon Great General of Darkness, his mecha was damaged and running out of power and he was badly hurt after a battle when he was informed that the Great General of Darkness -the biggest villain Badass of the Mazinverse- was approaching to challenge him. Everyone exhorted him to run away. What did Tetsuya do? Picking two swords and meeting The Dragon's challenge.
Badass: Tetsuya. That is NOT debatable. Great General of the Darkness is also an absolute badass. During his duel with Great Mazinger, he beat the crap out of the giant robot, and in fact he believed he had killed Tetsuya, declaring his victory before dying. And in a promotional material featuring all Go Nagai robots, he single-handedly crushed all of them -minus Shin Getter Robo, Grendizer and Mazinkaiser-, and the slaughter didn't stop until Shin Getter Robo and Grendizer showed up.
Beneath the Earth: The Mykene. Their civilization thrived in the Greek island of Bardos millennia ago. An earthquake destroyed their island and forced them to seek shelter underground. They lived below Earth for millennia, building their cities in networks of subterranean tunnels and caverns and grafting their bodies into Humongous Mecha to survive. Unlike fromn other examples from this trope they did not strictly harbored a grudge against humans... but they did not like them, nonetheless.
Berserk Button: Unless your name is Jun Hono or Kenzo Kabuto, do NOT EVER slight Tetsuya's skills.
And don't even try to hurt or threaten Jun or Kenzo, as a Mykene Battle Beast found the hard way.
Tetsuya: "Jun was a very special person to me! GUILLOTINE KICK!"
Several Mykene Battle Beasts found the hard -and extremely painful- way. Great Marshall of Hell being one of them.
In an arc of the Gosaku Ota episodes, a Corrupt Corporate Executive thieved Great Mazinger's plans to produce and sell his own Humongous Mecha. One of his imitations managed to defeat Great Mazinger (by preventing Tetsuya from docking). When Kenzo, Tetsuya and Jun tried to convince him to stop building Humongous Mecha, the man told they were just jealous of his robot was stronger than Great Mazinger. Tetsuya inmediately lunged at him, shouting he had NOT lost.
Bigger Bad: He played this role in the first series.
Big Creepy-Crawlies: Overlapping with Animal Mecha, one whole host of the Mykene Empire army were bio-mechanical, massive insects. Their commander, General Scarabeth, resembled a gigantic rhinoceros beetle.
Big Damn Heroes (Tetsuya's forte. Even his debut was a Big Damn Heroes moment in the final episode of Mazinger Z, where, fresh off beating Dr. Hell, a new, more powerful army appears and promptly whups Mazinger Z. When all hope seems lost, the brand shiny new Great Mazinger shows up on scene and proceeds to hand the new enemies their butts. Tends to happen a lot in the remakes, generally kicked off with a nice, big Thunder Break).
Brain in a Jar: The Kedora. Ken Ishikawa one-shot "The Relic of Evil" revealed that the Mykene controlled their Robeast by grafting the brain of a soldier taught to destroy all non-Mykene civilizations into a parasitic organism, and it fused with a robot, giving the Mykene soldier complete control. They would show up later in Shin Mazinger.
Breakout Character : Tetsuya Tsurugi, in Super Robot Wars Alpha. In the first game he is simply an extension to Koji's storyline. In Alpha Gaiden, he is featured in such an extent that the fanbase pretty much considered him the Main Character of Alpha Gaiden, note that Tetsuya is the only non OG character who has been considered as one.
Breath Weapon: Great Typhoon. Great Mazinger blows a jet of wind from its mouth grill to blow the enemy away. It is similar to Mazinger's Rust Tornado, but without the rust effect. Many Warbeasts also had breath-based attacks, usually expelling out fire, acid or even poison. One of the seven armies of Mykene Empire (the Reptilian Warbeasts) specialized in this kind of weapons.
Brother-Sister Incest: This is an example where the issue is avoided due to them being adoptive siblings. Tetsuya and Jun were two orphan kids Prof. Kenzo Kabuto adopted. So they technically are family and in fact grew up together. However they are not related by blood at all, so nobody seems minding they are the Official Couple, and the issue is never brought up.
Butt Monkey (General Hadias's role in a nutshell, he only gets to use three of his warrior beasts in the entire series while the other six generals use much more and multicapable robotic types pretty much take over the second half of the show (although they are shown much earlier). However, he is the only general in the show to hold his own against the Mazingers in the final showdown).
Similarly in Mazinger Z vs. The Great General of Darkness, Dante is the only spectral type warrior beast while the other six classes have two members.
Hadias and his warrior beasts get better treatment in the Super Robot Wars games though with Mamirez being the only spectral type not to appear in one to date.
If he's not potrayed for his status as The Ace or Ace Pilot Tetsuya Tsurugi in Super Robot Wars 4koma is this. Any single hole within his character is played for laughs.
Card-Carrying Villain: Dragon-in-Chief Great General of Darkness (Ankoku Daishogun) was very clear about his goals: he wanted the ancient Mykene civilization returned to the surface world and felt the light of Sun for first time in milennia, and he thought conquering the surface and wiping the whole humanity out was the only way to accomplish that. However, Big Bad Great Emperor of Darkness didn't make clear that was his motivation. Then again, he was Hades. It's a bit hard not being evil when you are a God of Evil.
Classical Mythology: It has an increasingly important role in the trilogy. Dr. Hell finding several Humongous Mecha in the underground mazes of a Greek island has its basis on the Greek legend of , the giant man of bronze that protected Creta. Gorgon's Robeasts resembled gods, heroes and creatures found in the Greek myths. And in later retellings of the story (Z-Mazinger and Shin Mazinger), Mazinger-Z turns out to be Zeus and Emperor of Darkness becomes Hades.
Climactic Volcano Backdrop: One battle between Great Mazinger and Marquis Janus took place in Janus' Volcano Lair (in Gosaku Ota manga). As Tetsuya battled Janus and her troops, the volcano erupted and vomited lava, rocks and cinders, walls crumbled down and the place collapsed around them.
Clothing Damage: Jun Hono suffered from this more often than Sayaka (much to her disliking).
Combining Mecha: The Mecha Expansion Pack Augment type. Great Mazinger is powered by a little aircraft (Brain Condor) docking on his head. And later it got a second Jet Pack, the Big Booster.
Convection Schmonvection: Right like in the first series, many battles happened near volcanoes or IN volcanoes, and Tetsuya was protected from the asphyxiating heat, toxic fumes and other dangers by Great Mazinger's.
Cool Airship: Mykeros and Demonika, Mykene Empire flying fortresses and airborne carriers.
Face Ship: Demopnika's frontside resembled the square, long snout of a mammalian beast. Mykeros had multiple faces built along its entire perimeter in reality were gates to launch the Robeasts.
Crossover (Out of all 70's anime based on Dynamic Productions mangas Great has the biggest number of crossovers - one with UFO Robo Grendizer, one with Getter Robo, one with Getter Robo G and one with Getter Robo G and Grendizer at the same time).
Cyborg: Prof. Kenzo Kabuto and Archduke Gorgon. And if you keep in mind the Warrior Monsters were bio-mechanical Humongous Mecha were controlled by the brain of a Mykene soldier grafted into it, then you have to that series' Robeasts were giant cyborgs.
It is played straight with Kenzo. His sons, Kouji and Shiro grew up believing their parents had died cause a laboratory experiment that went wrong. However, Kenzo's father saved his son's life by turning him into a cyborg. However, neither of them told Kouji and Shiro he was alive because Kenzo was going to build a Humongous Mecha to repel the Mykene invasion they predicted, and train its pilot. And both his father and he wanted to shield Kouji and Shiro from danger and psychological shock. It was not a bad reason, even if it was somewhat weak because Juzo was also building another Humongous Mecha and he raised them, even if he hired a maid because he was nearly always absent. When Kenzo revealed the truth to his little son, it took a long while for Shiro forgiving him. Though Kouji forgave him right away.
It is subverted with Kouji and Shiro's mother in the original series. In episode 90 from Mazinger Z, their mother appeared in the Institute, revealing she was alive and asking meeting her sons before telling them why she let them believe she was dead during years. Shiro was happy of getting his mother back, but Kouji was distrustful. It turned out that Kouji was right. Their mother was truly dead and that woman was a cyborg fabricated by Dr. Hell to infiltrate the Institute and destroy Mazinger from within. So her "good reason for abandoning them" was false.
Danger Room Cold Open: The Fortress Of Science was equipped with one of these. It appeared for first time in episode 3, and the scene showed Jun dodging rounds of machine gun mounted on the walls as Tetsuya her training and gave -or better said, barked out- advice.
Dangerously Genre Savvy : The Mykene. Oh god the Mykene. Not only most of them are a good fighter and thinker, they know that the biggest weakness of Great Mazinger, is the fact that it is a piloted robot. This resulted in Near Villain Victory for the Mykene as early as the third chapter.
Darkest Hour: In the anime it happened in the last episode: the Mykene bombarded the Fortress of Science, Kouji and Tetsuya were forced to fight separately, Tetsuya was defeated and nearly got killed and Prof. Kenzo Kabuto died. And in the Gosaku Ota episodes it was worse AND things went downhill.
Nevertheless, in that same manga the Darkest Hour happened in one of the last arcs: Great Marshall of Hell blackmailed the Government into destroying the Fortress of Science, Great Mazinger and Venus A. The Fortress was blown up to bits and crumbled into the ocean, the heroes were forced to flee and hiding, and while they were seeking a shelter and lying low, the Mykene army conquered Japan.
Death from Above: Great Marshall of Hell fabricated a massive lens of ice orbited around Earth and worked like a Kill Sat by focusing sunrays in one single point and blasting it with a massive, hot-melting heat ray. It appeared only in one of the manga continuities, though.
Deflector Shields: The Fortress of Science was equipped with a deflective energy barrier that surrounded the whole building to repel the strikes of the Monster of the Week and raids of enemy ships and airships. Unfortunately, a strong enough War Beast could shatter the barrier by employing enough brute force, and the Co-Dragons were Dangerously Genre Savvy enough to search and blow up the devices that made the barrier working.
Destructive Saviour: When Tetsuya, Jun and Boss fight against Warrior Monsters... usually the battlefield gets destroyed. And if it happens in one city... there is no much city left to speak of in the wake of the battle. However one Gosaku Ota episode showed if Great Mazinger did NOT stop the Beasts, there would be not even ruins left: the planet would be turned to nothing but rubble littering the scorched land.
Detachment Combat: Tetsuya several times detached the Big Booster off Great Mazinger's back in midair so it flew towards the enemy and impaled it.
The Determinator: Tetsuya. Not matter how hurt he is or how badly damaged Great Mazinger is, he will NEVER give up (because in his mind giving up would mean he would let his surrogate father down). A Super Robot WarsManga plays with it, showing he can not care less if he is outnumbered or hurt.
Tetsuya: That's right... It's fine if you tell me... to fight... I'll keep answering with the same answer... MAZIN GO...
Disappeared Dad: Dr. Kenzou was absent from the lives of Kouji and Shiro (raised by Dr. Juuzou), and that comes to bite everybody in the ass later.
Distracted by the Sexy: Just how many times Boss ran into an obstacle because he saw Jun walking by and he stopped looking forward while he walked?
Doing in the Wizard : In the Mazinger versus Great General of Darkness, a prophet warns Boss and his gang -and later Kouji and his friends- about the inminent Mykene invasion. It turns out that in reality he was Prof. Kenzo Kabuto, father of Kouji and Shiro, who kenw about the Mykene for reasons having nothing to do with prophecies.
The Dragon (Great General of Darkness (aka Ankoku Daishogun). Co-Dragons include Archduke Gorgon, Minister Argos, the Seven Mikenese Generals (mostly Julicaeser), and Marquise Janus (Gorgon's successor after being destroyed by a Thunder Break in episode 22.)
Dr. Hell as the Great Marshal of Hell takes over his position starting in episode 36 after he dies in combat against Great Mazinger five episodes earlier.
Doomsday Device: Great Marshall of Hell loved to design and build them -right like he did back when he was Dr. Hell. One of those devices -appeared only in the Gosaku Ota manga- was a giant, ice lens orbited around Earth and worked like a Kill Sat.
Everyone Can See It:Tetsuya and Jun. Unfortunately, Tetsuya was even more oblivious than Kouji. How oblivious? He thought Jun would replace him with Kouji in spite of: Jun barely knew Kouji; and she had spend the whole series trying Tetsuya noticed her.
Lava Adds Awesome: One of the weapons of Marquis Janus' Island Base was an artificial volcano built on the island could vomit rocks and lava when Janus needed.
Exactly What I Aimed At: In the Mazinkaiser movie Tetsuya is fighting Angoras and Scarabeth. Tetsuya throws Great Mazinger's Great Boomerang and right after shoots Great Typhoon. Both attacks miss, both commanders laugh and ask where he is aiming at... when Great Mazinger's boomerang slices them both from behind. As he is dying, Scarabeth -Mykene army's best tactician- realizes Tetsuya had missed his boomerang throw on purpose, and he shot Great Typhoon to change the boomerang's trajectory. So he caught them by surprise and killed both of them at once.
Final Battle: It varies depending on if we are discussing the Go Nagai manga, the anime series or the Gosaku Ota manga. In the anime version, Great Marshall of Darkness sent several Warrior Monsters to attack the Photon Energy Research Institute as Demonika -his Cool Airship- stealthily approached the Fortress of Science. Kouji fought a powerful Warrior Beast but Tetsuya (who was irrationally jealous) refused to sortie to help him. Finally he deployed Great Mazinger, and Great Marshall chose that moment to attack. A Warrior Monster attacked Tetsuya as Demonika started bombarding the Fortress. Tetsuya was easily shot down and cut off reinforcements. Dr. Kabuto then commited a Heroic Sacrifice to save him. After retrieving his corpse, Mazinger-Z, Great Mazinger, Venus A and Diana A regrouped and attacked Demonika together, blowing the Mykene army up to Hell. The manga versions are similar, but there is a very important difference in the Gosaku Ota version: Tetsuya commited Heroic Sacrifice, self-detonating Great Mazinger to destroy Demonika and the Mykene army.
Finishing Move: Technically, the first proper one of Super Robot Genre is Thunder Break. Unlike his predecessor, Thunder Break serves as both Tetsuya's most used and iconic weapon, and his finisher against most of his opponents.
Good Scars, Evil Scars: Kenzo Kabuto has a scar runs along of the left side of his head, atopping right above his eyebrow.
Good Wings, Evil Wings: Great Mazinger had two sets of wings: two red metallic wings unfolded from its back, and Big Booster (a grey Jet Pack docked its back. Big Booster wings were triangular and grey-colored). Several squads of the Mykene Empire army were formed by animal-shaped, bio-mechanical Robeast (such like the Avian army or the Insect army), so it was usual seeing Monster Warriors equiped with wings of bat, bird or insect.
Grand Finale: Kouji and Tetsuya's rivalry reaches a boiling point when the Mykene army attacks Mazinger and Tetsuya refuses helping Kouji. Finally, he gets talked into launching Great Mazinger, only to be shot down by a War Beast was awaiting for him. At the same time, flying aircraft Demonika appears and starts bombarding the Home Base of the heroes. The Professor Kenzo Kabuto (Kouji's biological father and Tetsuya's adoptive father) commits Heroic Sacrifice to save his adoptive son. Tetsuya suffers a Heroic BSOD, realizing his fear of losing his father has brought about his father's death, and Mazinger, Great Mazinger, Aphrodite and Venus combine forces to annihilate Emperor of Darkness' Co-Dragons and blowing up their fortress. And in one of the manga versions, Tetsuya committed another Heroic Sacrifice to atone for what he had done.
Gut Punch: In the Gosaku Ota manga the punches started when the Mykene blew up a coast city after Great Marshall of Darkness replaced the former deceasedDragon-in-Chief. In a few episodes the Japanese army threw an attack against the heroes and their Home Base, Prof. Kabuto went through a Despair Event Horizon, the Fortress of the Science got destroyed, forcing the heroes to run away and lie low, the Mykene burnt Tokyo to ashes, conquered Japan and crafted a Kill Sat, obliterating whole cities. Then you have the Final Battle. The heroes were busy building a new Home Base when the Mykene army launch an attack. Misato gets sliced in half in front of Tetsuya as he is unable to do anything, Mazinger-Z and Great Mazinger are trashed, Prof. Kabuto dies to save Tetsuya, and in reaction Tetsuya, realizing it was his blame commits a Taking You with MeHeroic Sacrifice. The Final Battle in the anime version was not quite so brutal, but in exchange you had a scene where Prof. Kabuto dies in arms of his son Kouji.
Hidden Depths: Tetsuya appears to be a simple superior and arrogant "second Koji" at first sight. After some way through the series, his character begins to be shown to be MUCH deeper than what it is at first, including a Deconstruction of the same character Archetype that he introduced in mecha shows. Consider that most of this pages entry are about Tetsuya and his characterization and you get the idea.
Home Base: The Fortress of Science was the place where the heroes lived and their HQ to fight the Mykene Empire. It stood out in sea beside the Japanese shoreline and it could submerge -doubling like an Underwater Base-. Some parts of the building could detach off the remain and work like a submarine or a flying carrier. Mykene Empire Home Base was necessarily an Elaborate Underground Base because they were a civilization lived underground.
It also was parodied. In the second episode, Boss' gang were looking for a Home Base for his Humongous Mecha. When finally they found one, Boss was pretty angry it was nothing but a rundown shack with one wall crumbled and holes on the roof.
Volcano Lair: Like noted above, an artificial volcano had been built in the center of Janus' Island Base. Its eruptions could be set off and stopped at will. Often it was used to blast Great Mazinger with a rain of hot-molten rocks, debris and volcanic cinders in order to slow down its advance or hinder Tetsuya as he battled.
Honor Before Reason: Tetsuya is very hotheaded, and he will always refuse running away even when it would tactical sense making so. Great General of the Darkness also wanted challenging Great Mazinger to a solo duel to redeem his tarnished honor.
I Control My Minions Through...: Great Emperor of Darkness was a God Emperor, so he used Authority, Fear, Loyalty, Power and Divine Right. His minions were loyal and respected his authority because he had protected the whole Mykene civilization when they were forced to hide underground, and because its power (in Shin Mazinger his real identity was Hades).
If It Swims, It Flies: Great Mazinger was also equipped to fly and swim, and faced the same problems its antecessor.
Impaled with Extreme Prejudice: Big Booster was a Jet Pack with a huge, retractable metal spike. One of the Tetsuya's favorite moves was throwing the Big Booster suddenly and impaling his enemy when it was flying.
Inferiority Superiority Complex: Tetsuya, very much. When you suspect your adopted sister will dump you for someone she barely knows, and at the same time get mad if someone questions your skills, you know you have this.
It's Personal: Fighting the Mykene army was not a personal matter for Tetsuya... until Professor Kabuto died. THEN it became personal right away. In the Ota manga chapters, Tetsuya has a personal grudge against Marquiss Yanus after she tore Misato in half in front of him.
Jet Pack: Great Mazinger had a red Jet Pack folded from its back, and a second Jet Pack (Big Booster) docked with it. It was grey, with wide triangular wings, and was equiped with a spike to impale Robeasts. Venus-A also had an attachable Jet Pack, right like Mazinger-Z.
Jumped at the Call: Tetsuya has been a Mecha pilot most of his life. He devotes himself to his job, loathes the idea of being just normal and is perfectly right with having to kill giant monsters. However he used to be a lonely orphan little kid yearned for having a father. When Prof. Kabuto told him he would adopt him if he was willing to train to pilot a Humongous Mecha and defeat ancient bio-mechanical monsters from Beneath the Earth, Tetsuya agreed gleefully. Nevertheless, his obsessiveness combined with his abandonment issues, lacking of self-confidence and self-worth and a massively low opinion of himself (that he tried to hide behind of a mask of arrogance and pride) led to many troubles and finally to a masive breakdown. Jun also jumped at the call, but she managed to get it more together than him.
Kill Sat: Great Marshall Of Hell's giant lens of ice.
Made of Indestructium: Just like Mazinger Z, Great Mazinger is made of Japanium, a rare metal can be found only in Japan. However Mazinger Z is made of Super Alloy Z whereas Great Mazinger is made of New Super Alloy Z, which is even sturdier and tougher.
In the Mazinger-Z versus Great General of Darkness movie it is said the legions of Mykene Warrior Monsters are commanded by Great General of Darkness. He seems to be the supreme leader of the Mykene Empire. In first episode of Great Mazinger we learnt he is the supreme commander of the Mykene army, and he is under the orders of the Emperor of Darkness (also known like Hades).
The Mole: The Mykene Empire had a mole infiltrated among Dr. Hell's henchmen, Archduke Gorgon, and Marquiss Janus tried to infiltrate into the Fortress of Science once by pretending being an average human girl.
Monogender Monsters: Nearly all War Beasts were male. Maybe the only exception in the whole trilogy is Marquisse Janus, since her Humongous Mecha was clearly female-shaped.
In the Gosaku Ota manga episodes, Great Marshall of Darkness sucessfully blackmailed Japanese army into destroying Great Mazinger and the Fortress of Science. The army bombarded the Fortress and stormed into the place before blowing it up completely, and the heroes were forced to flee and lie low for a while. Meanwhile, Mykene army conquered Japan.
In the last episodes of the anime and Gosaku Ota manga, the Mykene army struck the Fortress and in the manga, Marquis Janus traped Misato and cut her in half, and attacked Mazinger-Z and Great Mazinger separately. Kouji and Tetsuya nearly got killed, and Prof. Kabuto commited a Heroic Sacrifice to save Tetsuya. The generals of the Mykene army laughed. Five minutes later they were not laughing.
Perhaps, to show how Darker and Edgier this series is, the first chapter of the manga that Tetsuya started becoming the main character already have this. Jun is kidnapped and become a hostage, resulted in Tetsuya being unable to attack, and even if he can, he cant see well thanks to the snowstorm. Its the victory for the villain for sure, had Boss didn't interfere during the fight.
Not So Different : Proud of their skills as a warrior, protecting their kinds, yet prefer to show their superiority in combat towards their enemy, admires someone who can math their own skills, and many more to list. Yes, the only difference that Tetsuya have against the Mykene generals, especially Ankoku Daishogun is the fact that he is Human.
This get elaborated in Super Robot Wars Alpha Gaiden, where Tetsuya laugh in happiness after knowing that the Mykene is alive and he can fight them at that time.
Once per Episode: In the same way and with the same purpose, Tetsuya shouted "Brain Condor!" and "Mazin Go". And Jun shouted "Queen Star On! Venus Go!" every episode after the third one.
OOC Is Serious Business: Tetsuya is serious, grim-looking and moody, and he seldom smiles. So when he grins, everyone freaks out and dons Oh Crap stares. Mainly Warrior Monsters, since it usually means they are about of dying horribly and painfully.
Orcus on His Throne: The Emperor of Darkness. He never left his throne in the Underworld, not even when all generals of his army were killed.
Papa Wolf: It is arguable if Kenzo was or was not a good father. It is not arguable when one his older biological son was about of being killed he sent a Humongous Mecha after the people was harming him. And when his adoptive son was about of being killed, he blew his assailant and himself up. Therefore, you do NOT want to threaten the lives of his sons.
Proud Warrior Race Guy: The Mykene. Many of them were warriors highly proud of their skills and eager for testing them, and their Robeasts were made by grafting into the body of a Humongous Mecha the brain of a soldier indoctrinated to fight and exterminate all non-Mykene civilizations.
Red Oni, Blue Oni: Tetsuya and Kouji. Surprisingly, Kouji is the blue one, since he had matured somewhat in America and tried thinking strategically(not to mention having quite a lot of combat experience), whereas Tetsuya's jealousy turned him rash and impulsive.
Power Fist: And its fists are reinforced with cutters run along the forearms.
Hand Blast: Great Mazinger's Thunder Break. The Humongous Mecha gathered lightning bolts from the atmosphere and blasted its enemy with it. Tetsuya came up with a bunch of variations: Great Mazinger shot a continued stream of electricity from its forefingers, launched lightning bolts from its open palms -or fingertips-, powered up its sword with it...
Rule of Three: It was not so blatant like in the first series. Still, three Humongous Mecha fought the Mykene. Great Mazinger, Venus-A and Boss Borot. Boss Borot was driven by three pilots: Boss, Nuke and Mucha. The Bridge Bunnies are three. Prof. Kabuto had three sons Tetsuya, Kouji and Shiro...
In one of the Go Nagai manga chapters a Warrior Monster was holding Jun hostage. Tetsuya did not dare to attack the Monster, but Prof. Kabuto ordered him throwing his doubt out and attacking (in spite of Jun was his adoptive sister, Battle Couple and Love Interest).
In the Gosaku Ota episodes, Great Marshall of Hell -Big Bad's second The Dragon- blew up one city and threatened with destroying Tokyo as well, unless the Japanese Government destroyed the Fortress of Science and all Humongous Mecha stored there. The Government gave in and destroyed the Fortress. Great Marshall turned Tokyo into a wasteland nonetheless.
Ship Sinking: Tetsuya / Misato. Misato was Boss' cousin and a secondary character during Mazinger Z last season. She also showed up in the Great Mazinger manga penned by Gosaku Ota. Even though he liked Jun, Tetsuya found himself attracted to her, but then she got brutally murdered by Marquis Janus. Tetsuya himself died shortly after commiting a Heroic Sacrifice.
Shock and Awe: Thunder Break, which is a directed lightning strike from Great's pointer finger. And later, Double Thunder Break which uses both hand to direct the lightning strike.
Sibling Rivalry: Tetsuya and Kouji were a pretty tragic example. Kouji was Kenzo Kabuto's biological son. When Kenzo got reunited with Kouji, Tetsuya believed his father would forget about him now his son by blood was back. He got very jealous and argued and fought with his adoptive brother about anything and everything, determined to prove to their father that he was the better than Kouji. Unfortunately, his jealousy and his bickering caused Kenzo's death. He suffered a Freak Out! cause it.
Sibling Team: Tetsuya and Jun, being adoptive siblings, combined this trope with Battle Couple. Also, Tetsuya and Kouji when they fought together.
Sizeshifter: Marquis Janus could change size, although she -and her Humongous Mecha- became smaller instead of bigger (Justified since she was a spy and by dwarfing her mecha to human size she could blend between humans), so maybe it invers the trope.
Sliding Scale of Idealism Versus Cynicism: Even though it is darker and more cynical than Mazinger Z, this series is still plenty idealistic. Only mustering all of their courage, heroism, unwillingness to give up and belief in the humanity, he heroes were able to carry forward and win.
The Smurfette Principle: Jun Hono was the only female character between the heroes (and Marquiss Janus the only female member of the Mykene high command. Then again, the remainder members were humans whose brains had been grafted into Humongous Mecha, so it was hard telling). That changed during the last chapters, when Sayaka was Back for the Finale and the male to female ratio became 3:2. In the Gosaku Ota manga, Misato again was a recurring character in the last arcs, so the ratio became 3:3.
Sniping the Cockpit: In the Mazinger trilogy aiming for the cockpit (clearly visible in Mazinger-Z and Great Mazinger) is a common tactic constantly employed by Genre Savvy villains... and the army when the Government turns on the heroes (which also is an alarmingly common occurrence). In fact, it happened in the first Mazinger-Z manga chapter. And in a Great Mazinger manga episode, a Warbeast is holding Great Mazinger still as Marquis Janus orders to snipe the cockpit. However, the likewise Genre SavvyHumongous Mecha builders had the cockpits specially reinforced to protect the pilot.
Speech-Impaired Animal: Bakarasu was a raven ("Bakarasu" roughly means "Dumb crow") Boss and his gang used as a lookout or a messenger. In return, Bakarasu mocked Boss, annoyed him and drove him mad. Bakarasu strangely could talk -and laugh, usually at Boss-, and theoretically it worked alongside Boss, Nuke and Mucha, but in reality it did whatever it pleased. It only had one appearance in Mazinger Z (episode 69), but he showed up in several Great Mazinger episodes.
Stock Shout-Out : An inverted example. Reference and shout outs to Great Mazinger is pretty overused in suceeding anime.
During one arc of the Gosaku Ota manga, Tetsuya had to fight nine Mass-Production Great Mazingers were invading the Fortress of Science. Considering he is an arrogant HotBloodedAce Pilot with huge confidence issues, is not a bad guy -he may be even nice- but is a jerk when he is angry... Does it remind you of anyone else?
Sword Fight: Great Mazinger was the first Humongous Mecha used swords like weapon (even before Voltes V or Go Lion). Tetsuya was quite profficient using them, and he even did Dual Wield. Naturally he had several sword duels throughout the series, the most famous and most fondly remembered against BadassThe Dragon Great General of Darkness.
Tail Slap: Several Warrior Monsters (such like the whole Reptilian Warrior Beasts division) were endowed with powerful tails, capable to hit or coil around the enemy and strangle it. Often they had some weapon attached or shot missiles, acid or poison.
Tagalong Kid: Shiro Kabuto, right like in the original series.
Take Over the World: The Mykene were an ancient civilization had been forced to survive underground for millennia. Big Bad and Physical God Emperor of Darkness and The Dragon Ankoku Daishogun wanted to return to the surface world and let their people enjoy sunlight, fresh air and clean water, and they thought take over the world was the only way to achieve that.
The Team Normal: Boss and his gang -Nuke and Mucha-, right like they were in the original series.
10-Minute Retirement: From all possible times, The Hero did this during the Grand Finale. Tetsuya had grown so jealous of Kouji, falsely believing everyone were going to replace him with Kouji and forget about him (for all his bluster, he has issues). Telling his attitude bit him in the butt is a gross understatement.
Technician Versus Performer: Koji and Tetsuya has a dinstinct way to pilot their own Mazinger. Koji is the Technician, who uses his weapons in normal way, such as Mazinger's Photon powered Eye Beam as a long range weapon, pure brute force and combine it with Combat Pragmatism. Tetsuya is the performer who combines his own Combat Pragmatism by using Great's wide arsenal of weapon in an unorthodox way, such as using Thunder Break as weapon infusion, Swords as Lightning rods, more directed version of Thunder Break, his surprisingly weird way of handling swords, and covering Great with the heat energy of Breast Burn(which later adapted in Super Robot Wars Alpha by Mazinkaiser for Kaiser Nova).
Telescoping Robot: Great Mazinger stored one sword into each shin, several cutters blades along its legs, and the buckle-like glass adorning its midsection in reality was a hatch opened up to launch a missile from. Oh, and two wings and a Jet Pack unfolded from its back.
Thematic Rogues Gallery: The Mykene's Warrior Beasts, split in seven thematically-organized divisions: the armies of Superhumans, Evil Ghosts, Mammalian, Avian, Aquatic, Insect and Reptilian Battle Beasts.
This Is Unforgivable: Right like his predecessor, Tetsuya was prone to spout this line when he got angry.
Those Two Guys: Nuke and Mucha, best friends and tag-alongs of The Rival and Butt Monkey Boss long before the start of the series. Before meeting and befriending Kouji Kabuto they were two average, ordinary high-school students, but after meeting him their daily life includes battles between Humongous Mechas, fighting or fleeing from armies of Mooks, sneaking into enemy secret bases and basically surviving. Often they get -unwillingly- dragged -by Boss- in Kouji's adventures, and they provide with the rational counterpoint -and lampshading- to any stupid stunt Boss has come up with. Later in the series Boss got himself a Made Of Junk Humongous Mecha and required that they helped him to pilot it -much to their chagrin-. In Great Mazinger their situation did not get more normal, that with the monsters from Beneath the Earth invading the surface world bit and Boss demanding they help him to fight them like part of an absolutely helpless plan to woo Tsundere Jun Hono -Love Interest of The Hero Tetsuya, whom Boss can not stand-.
The Three Faces of Adam: Prof. Kabuto is the prophet (reinforced in he pretended being a prophet in a feature), Tetsuya is the lord and Shiro is still the hunter, encouraged by Jun to become a lord.
Throwing Your Sword Always Works: Tetsuya sometimes uses his robot's sword like a spear (the first time he did that was during his first appearance!). However, he holds it overhead like if it was a real spear when he does that, giving more verosimilitude to the action.
Token Minority (Jun is a half-black female lead *and* the love interest for the main character, reasonably impressive for a 1970s Japan kids' show.)
Tokyo Is the Center of the Universe: Subverted. For start with, the Headquarters of the Fortress of Science are not located in Tokyo on the Japanese shore. Therefore, the enemy feels not compelled to exclusively target and attack Tokyo. A lot of Japanese cities are destroyed, and in the Mazinger Z versus Great General of Darkness, the Mykene army struck New York, Londres and Moscow before striking Tokyo.
Tsundere: Mazinger Z had Sayaka, Great has Jun. Both of them have little patience when The Hero goes stupid. Jun, however, also has her own problems to deal with...
And this time, Tetsuya himself. He bickers a lot with Jun, but on the inside, he cares for her in more than brother sister manner (they are adoptive siblings in case you forgot).
Two-Faced: Marquis Yanus has a human-looking face she uses to blend among humans and her true face, located on the "back" of her head. When she wants to switch to her true face, her neck turns one-hundred-degrees and her locks part sideways, revealing a demoniac face underneath it (She seems a demon or a Hanya). It is so nightmarish like it sounds.
Unbuilt Trope: Tetsuya is not only similar, he is EXACTLY what Asuka is made to deconstruct, word for word. He is a Hot-BloodedAce Pilot that is so arrogant that anyone that questions his skills will have a trouble with him. That same arrogance also made him bickering with Jun, and Tetsuya Would Hit a Girl even though Jun is both his Love Interest, his Battle Couple, and adoptive sister. On the other hand, he has a massive inferiority complex, and his lacking sense of self worth and constant fear of being replaced became FAR more apparent after Koji's return, which caused so many problems that later resulted in Kenzo's death.
And, much like Asuka Langley Sohryu, he had to pay a very heavy prize to learn his lesson.
And in one of the Great Mazinger manga back in the seventies he had to fight nine Mass-Production Great Mazingers... Yes, he is Asuka's template, definitely.
Unexplained Recovery: At the second-to-last episode, the Cool Airship where Dr. Hell was escaping got blown up. Whatever got left from him after that explosion surely sank in the ocean. Nonetheless he showed up again in the last season, his body grafted into a Humongous Mecha. One eyepatch covering his left eye was the only mark of the ordeal he had endured. Little explanation was given other than an statement of Emperor of Darkness had relived him and turned into one of his Warrior Monsters (and high commander of his army). It can may be worth mentioning many Mazinger-Z characters returned in the last episodes from the sequel, so maybe Executive Meddling was involved.
The Unfavorite: Kenzo Kabuto had two biological sons (Kouji and Shiro) and two adoptive children (Tetsuya and Jun). Although Tetsuya was clearly his favorite, he still showed he cared for Kouji and Shiro. However, he got Jun completely neglected, treating her like a soldier, not making anything about her feelings of abandoment and her inner tensions, and he seldom shown he cared for her. It went so far that, before dying after his Heroic Sacrifice he pleaded Kouji that he treated Tetsuya like his brother and took care of Shiro... but he did not mention Jun at all. Nonetheless, his attitude drove Jun to think she could not be dependant on someone else and to develop a very strong-willed and self-reliant personality.
Ungrateful Bastard: Tetsuya and Jun had the same kind of gratitude and regard Kouji and Sayaka received for their world-saving efforts. Or even worse. In the manga episodes penned by Gosaku Ota -one of the Go Nagai assistants-, Great Marshall Of Hell warned he would blow Tokyo up unless the Home Base and the Humongous Mecha of the heroes were destroyed. People demanded the Government yielded... And they did. The Fortress of Science was destroyed, and Tetsuya and his allies were forced to flee and lie low for a while. During that time they had absolutely NO help to try and keep defending the humankind. They got many insults, though.
Use Your Head: Tetsuya is an even bigger of an offender than Kouji with this.
Villainous Breakdown: Great Marshall Of Hell -The Dragon of the second season- also had several of them at the end of series, mainly in the Gosaku Ota manga continuity. His expression and subsequent fit when Venus-A shot the flying fortress Mykeros down was particularly beautiful.
"Well Done, Son" Guy: Tetsuya was an orphan with a ton of abandonment and self-confidence issues. He constantly and gleefully risked his life on a daily basis by fighting ancient, giant monsters from Beneath the Earth so his adoptive father approved of him. Kenzo actually was proud of him, but he hardly thought of telling Tetsuya that, being more concerned with disciplining him when Tetsuya did or said something stupid (and since Tetsuya was a Jerkass Woobie and an Idiot Hero, it happened frequently). Because it, Tetsuya was always deadly frightened of losing his father if he was not good enough, and he got a breakdown at the end of the series when he thought it might happen.
