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.
A bigger example is 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 he was building a Humongous Mecha to defend humankind. When Kenzo revealed the truth to them, Kouji was too glad to hold a grudge, but Shiro took a long while until before he could forgive him. Also, Kenzo had no troubles slapping his adoptive son when he thought Tetsuya was crossing the line. All of it finally bit everyone's butts at the end of the series.
Justified, considering what happened in the series, its rather understandable why he didn't reveal himself to be alive, since he took care of Tetsuya and Jun. How he treated Tetsuya on the other hand, is a good example. During one the first chapter of the manga, he ordered Tetsuya to throw his doubt and attack the enemy who hold Jun hostage(which is not only his love interest, shes technically his family). Sure, Tetsuya is a trained soldier, but the way that Tetsuya reacts shows how much of a Sadistic Choice it really is.
Another Mazinger Z character who suffered due to Abusive Parents was... Big Bad Dr. Hell himself. Like it was seen in the manga continuity penned by Gosaku Ota (that gave a backstory to most of the villains), since he was a child his mother abused him physically and emotionally (insulting him, stating openly she did not want getting kids and she would be better off if he would have never been born...) as his father shrugged off indifferently. The physical and psychological mistreatment he suffered back then is one of the reasons he decided Humans Are Bastards and he became so unhinged.
Ace Pilot: In the trilogy, Kouji -like Duke Fleed- had to grow into the role. In the first chapters it was painfully obvious than he had no idea of how piloting a war vehicle. And the consequences of it were just so painful to him. Nevertheless, through training and battles he became a true ace. In contrast, Tetsuya Tsurugi not only was trained into it before the series but also he is the Trope Codifier -and Deconstruction- by Hot-BloodedAce Pilot in Humongous Mecha anime.
Accidental Pervert: It happened several times, not only to Kouji but also to Sayaka. One example of it was original manga's episode 8 when they saw each other naked in the hot springs. Curiously there was not slapping or reproaching. After the initials screams they calmed down and apologized at each other. It was even cute.
And in the Mazinger vs Great General of Darkness movie, Kouji accidentally walked in Sayaka when she was having a shower in one of the first scenes. This time he was slapped.
Action Girl: Sayaka was among the first action-geared ladies in Japanese anime
Achilles in His Tent: Kouji did this — out of all people! — in episode 7. After mobs of people expressed their displeasure in having his hometown leveled by a Humongous Mecha battle by harassing him and after a quarrel with Sayaka, Kouji decided since nobody wanted him fighting, he would stay in home. Of course, it did not last long.
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-.
Adults Are Useless: The series plays with the trope, but subverts it. The most powerful weapon in the world is handed over to a teenager, and Dr. Hell and his servants (who are all adults) are unable to defeat a bunch of teenagers... but neither Kouji nor Sayaka nor Shiro — nor Boss and his gang — would have been capable of protecting humankind and defeating Dr. Hell if they had not been supported by plenty of adults. All workers in the Institute (starting with Prof. Yumi, who was a good scientist and strategist) were fully competent and without them Mazinger Z would not have gotten the frequent upgrades, repairs and maintenance it needed.
Advanced Ancient Acropolis: The Mykene inhabited the Greek island of Bardos. Their technological 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: Dr. Hell started sending flying Beasts after Kouji and Mazinger-Z as soon as the episode 19. Mazinger got a Mid-Season Upgrade to grant him flight capabilities in episode 34, and in that same episode Kouji got his first aerial battle (Against Genocyder F9). Since that moment and through the whole series he had many climatic aerial duels against flying enemies like Kirma K5 (who used hit-and-fly-off tactics) or Jeiser J1 (that could easily blast Mazinger away, was impervious to his weapons and forget Kouji to chase it across the sky in spite of Mazinger was nearly out of power and the cockpit was smoking).
Airborne Aircraft Carrier: Ghoul, a flying fortress commanded by Count Brocken. It had capability for housing a large number of Brocken's Iron Cross troops, dozens of combat jets and Mechanical Beasts, and it could mask itself from radar devices, fly at high altitude and spend several months airborne without needing landing.
All Myths Are True: Dr. Hell joined an archaelogical expedition to the Greek island of Bardos, thinking maybe several ancient legends that told the island was defended by an army of mechanical giants were true. Unfortunately for everybody else, he was right. Classical Mythology plays an increasingly important role in each retelling of the series, until the point of Greek gods start showing up and Great MazingerBig Bad is revealed to be Hades in Shin Mazinger.
All There in the Manual: Many supplementary materials (such like the Mazinbible book) have been released, providing with additional information and backstory about the series and the worlds where they happen, their characters, blueprints of mechas and bases...
Almost Kiss: Kouji and Sayaka do this in the Mazinger-Z vs Great General of Darkness, right when Kouji is going to sortie with Mazinger-Z to fight a battle he knows he can not win, and thinking he'll die. Sayaka stops him to give him his little brother's birthday gift, and both stare into each other's eyes for a long while... and then Kouji turns around and leaves. Cue millions of fans groaning in exhasperation. In the manga version of that moment, though, they DO kiss.
Alternate Continuity: There are several manga versions. The original one was written and drawn by Go Nagai. A second version was drawn by Gosaku Ota — one of his assistants — that ran parallel to the anime series and was heavily influenced by it (That version was made when Sueisha realized two Mazinger Z mangas would make more profit that one). Gosaku Ota's manga showed the backstory of the Dr. Hell and his undelings. Other versions are: New Mazinger, Mazin Saga, Mazinger Angels, Shin Mazinger, Shin Mazinger Zero, diferent one-shots and short stories — one of them made by Ishikawa)... And then you have the different anime versions...
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: .
Ancestral Weapon: Kouji probably counts, if you count his grandpa's and his dad'sgiant robot as an ancestral weapon.
And The Rest: It happened constantly. Often the villains told a sentence along the lines of "Go ahead! Finish with Mazinger-Z... and the other two robots!". The other two robots being Aphrodite-A (or Diana-A) and Boss Borot. Needless to say, it was intended to be demeaning.
And This Is for...: In the manga, as they are making preparations for the Final Battle, Kouji tells -of course, loudly- that, for his poor murdered granddad, for all people has been hurt, and for the peace of Japan... THIS TIME HE'LL DESTROY DR. HELL FOR GOOD!
And in the second chapter of Shin Mazinger Zero she falteringly uttered she loved Kouji shortly before dying.
Animal Mecha: Several Mechanical Beasts resembled animals (insects, crabs, birds, whales, seahorses...), specially the Beasts commanded by Gorgon, which looked like mythological creatures (dragons, harpies...).
Applied Phlebotinum: Koushi Ryoku (Photon Atomic) energy is what Mazinger-Z is powered with. When it runs out, Mazinger ceases functioning. It was discovered by Dr. Kabuto (ironically, in the Gosaku Ota episodes, it was stated he was already investigating it back in college, and one of his classmates helped him by correcting his calculations. Name of that classmate? Hell). It is repeatedly stated and shown in the series Photon energy must be used in conjuction with a body made from Japanium, or the Humongous Mecha is less effective: either the weapons are too powerful and overload the computer and damage the armor, or the robot is sturdy but its weapons are weak.
Phlebotinum Battery: Mazinger Z runs on an engine powered by Photon Atomic energy. When it runs out of Photon energy, it ceases functioning and it has to be replenished to work again. Great Mazinger and Mazinkaiser also work with a Photon engine. Grendizer works with the same principle but with a completly different energy source.
Arc Words: "When you pilot Mazinger, you can become a god or a devil."
Arm Cannon: Besides shooting its fists, Mazinger Z hid a cannon in each upper arm shot drilling missiles. Several Mechanical Beasts had cannons (or even machine guns like Balkan P5) instead of limbs. A stands out example is Debira X1 (a beast seemed a blend between bat and vampire) had a hidden leg cannon (and blew one of Mazinger's arms off with it).
Armed Legs: Mazinger-Z had one rocket on each foot to propel it underwater, but Kouji also used them to fight. Usually he blast with them a ¨Mechanical Beast's face to force it to release Mazinger.
The series tried to avert this trope. Mazinger's cockpit offered little protection, and in the first chapters, Kouji repeatedly got hurt and even knocked out because he fought in civilian clothes (and in the manga the villains were aware of that and tried to exploit it. In an early story, Baron Ashura commanded a Mechanical Beast to grab Mazinger, fly high and drop it, knowing -as Kouji did- that the freefall's impact would kill the pilot, even if Mazinger endured it). In order to avoid that, he began wearing a Latex Space Suit to protect his body during the fights. It was more protective than plain clothes, but he still got injured while wearing it.
Attack! Attack! Attack!: Kouji falls into this sometimes, when he is facing a Mechanical Beast several times stronger than Mazinger and still he refuses retiring or playing defensive. However, he still is able to think strategically, come up with plans quickly, and every so often you can talk him into leaving the battlefield, so he is not the biggest offender in the series (that one would be Tetsuya).
In his battle against Jeiser J1 his enemy was too sturdy to be taken down easily, his mecha was quickly running out of power, the mechanisms were so strained that the controls were giving off sparks and the cockpit was filling with smoke, and he was risking to a freefall (since they were fighting in midair)... and still he refused going back to the Home Base, waiting for a chance to nail the Beast instead.
In the whole Mazinsaga the only method the army is capable to think to stop the Robeasts is attacking them endlessly, and when it fails, send more troops in. They DID get one sucess in the Gosaku Ota Mazinger-Z manga, though, but they needed a nuke to achieve it. You would think that after the first few times they would learn that Giant Equals Invincible.
Attack Its Weak Point: When a Mechanical Beast seemed too powerful Kouji, Sayaka, Prof. Yumi and the rest of the scientists of the Institute would examine footage of the battle to try to come up with a strategy or find a weak point. Good examples were Bikong O9 (its weak point were the horns jutting out of its head) or Jinray S1 (It was aMechanical Beast flew and struck at Match 5 speed. It beat Mazinger-Z and fled without Kouji even knowing what had hit him. However its weak point were the legs where its rockets were located. Kouji defeated it by destroying one of them).
Attack the Tail: In the Mazinger-Z vs Great General of Darkness feature, a serpent-like Robeast had one head on each end. The tinier head, located on the tip of the tail, was the REAL head (Mykene Warbeasts were controlled by grafting the head of a Mykene warrior into a Robeast), so when Kouji cut its tail off, the Warbeast lost control and it was destroyed.
Boom, Headshot: Baremos Q7 was a Mechanical Beast built with stolen samples of Alloy Z. However its head was made of a less sturdy metal since Dr. Hell did not have enough alloy Z. During the battle, Kouji eventually noticed the Robeast was ALWAYS protecting its head. Logically, he aimed for it. Another example happened in one of the first chapters, when he was told Bikong O9 weak point were its horns.
Go for the Eye: Gumbina M5's armor was completely impervious to Mazinger-Z's weapons. Kouji not even was capable of scratching or denting it. Its weak point were its large eyes located on the chest. Sayaka ended up the battle when Aphrodite-A's Torpedo Tits managed to hit them. Ouch.
In the "Mazinger-Z vs Great General of Darkness", Kouji was sword-dueling against a clearly superior Warbeast had pinned Mazinger-Z on the ground and was trying run its sword through it. Kouji shot Mazinger's drill missiles and managed hit one of its eyes. The Warbeast crumbled down due to the missiles boring into its head and exploding. Double ouch.
Ozones B3 subverted the trope. It had a huge, glowing, single eye on its head... but it was not its weak point, and Kouji did not try to destroy it.
Aww, Look! They Really Do Love Each Other: Kouji and Sayaka. Although in the original manga they got along well, the anime series took their Belligerent Sexual Tension up to eleven — and some of their fights were legendary. However, you always had moments where they stopped to get mad, bicker and insult each other and showed they cared for each other very much.
In episode 29 Kouji saw a Mechanical Beast — Grengus C3 — walking from the direction where Aphrodite A — Sayaka's Fembot — had gone at before. Inmediately he panicked, got on a bike and drove towards the place, yelling "Sayaka" all the way (he was so freaked out he did not realize the bike he had got was not his). When he finally found her — wounded and lying down on the floor beside Aphrodite A's remains — he shook her awake and hugged her.
And in another episode, Kouji and Sayaka got an actually serious fight, and Sayaka refused to back him up in battle. When he was seriously injured, Sayaka took care of him in the hospital and kissed him in his comatose sleep.
Back Stab: In the Gosaku Ota manga continuity, Dragon with an Agenda Archduke Gorgon murdered Big Bad Dr. Hell by stabbing him from behind with one sword when he was distracted. Afterwards he pulled his sword from the body, said "So long, old madman" and left him lying -and bleeding- on the ground, laughing all the way as he left.
Bad Future: In Shin Mazinger Zero the world and the entire mankind have been burnt to ashes by a Mazinger-Z turned Eldritch Abomination in the future, and Minerva-X sends Kouji back in time to save everybody. However they are locked into a Groundhog Peggy Sue loop since Kouji has failed every time so far, and Minerva keeps sending him back because she can trust no one else. They have repeated the same cycle almost three thousand times when the series starts, so it seems not matter what Kouji does, the world is doomed. Given that Minerva is the original Minerva-X, future in the Mazinger Z universe seems bleak, indeed.
Bad Moon Rising: In Grendizer, the Moon becoming red was a sign of the [Alien Invasion Alliance Vegan]] was getting ready another attack -and the main characters eventually learnt to watch for that-. One of the manga versions -penned by Gosaku Ota- reinforced that: in the first pages a red skull appeared on the Moon's surface (a sign of the Vegans had come) and Duke felt upset when he saw it, and wondered if that was a bad omen.
Badass Back: Hilariously subverted in the first chapter of Mazinger ZGo Nagai manga. Sayaka sortie in Aphrodite-A to stop a mysterious Humongous Mecha is trashing the city that mysterious Humongous Mecha being Mazinger-Z, "piloted" by a Kouji Kabuto had just got on the robot and had absolutely no idea of how controlling the damned thing. When she strikes it, the Humongous Mecha easily withstands its attack, heaves her Fem Bot, throws her away... and then it turns its back towards her. Sayaka is incensed, believing that robot thinks Aphrodite is not good enough to fight and is making fun of her. Her father is worried and requests her being careful because it is a monster is dangerous even if he has its back turned to her. She gets ready to attack, when the Humongous Mecha suddenly turns around... and its pilot manages to communicate with her and explain he did all that because he did not know how piloting the robot.
Badass Family: Dr. Kabuto and his son built the most powerful robots in the world. Kouji has fought and stomped whole squads of armed soldiers, and trashed dozens of massive war machines. Even his little brother is also perfectly capable defend himself on one fight.
Badass Arm-Fold: Kouji sometimes used the pose. A good example in an episode in which Mazinger-Z is nearly completely depleted from energy during a battle, the control deck is smoking and giving off sparks due to the strain, the weapons don't work, Prof. Yumi is ordering -''repeatedly- Kouji retreating because he'll die otherwise... and Kouji simply folds his arms across his chest as he calmly waits for one chance to blast the Beast down! It is hard to convey how Badass he seemed right then.
The Bait: Often Kouji voluntereed for the role. Sayaka, too. Boss could be more willing or more reluctant to play bait depending on the situation.
Baleful Polymorph: In a story of the Gosaku Ota episodes, a race of giant, man-eater, fish-alike, humanoid Eldritch Abominations from another dimension named Chip Kamoy tried to invade Earth. They kidnapped a normal human girl and transformed her into a mermaid-like being to communicate with humans. Later they trapped The Hero Kouji Kabuto and she helped him to escape. In punishment she got executed by the Chip Kamoy.
Barbie Doll Anatomy: In the original anime, Kouji had some shirtless scenes, and nipples were nowhere to be seen.
Partially averted in Mazinkaiser: when Sayaka's top comes undone in the fourth episode, the nipples and areola are present and accounted for. Don't know where the male nipples are hiding, though.
Barehanded Blade Block: Kouji was forced to pull this maneouver sometimes. A specially awesome example happened in episode 52: he is fighting a Mechanical Beast armed with scythes can easily slice and dice his Humongous Mecha. During the fight the Beast tries to cleave Mazinger in half... and Mazinger blocks the scythe with both hands and splits it. And then he grans his enemy's broken weapon, slice its remainder scythe off, and stab the Robeast with its own weapon! Justified Trope since Kouji does this using his Humongous Mecha, so he does not need get worried about losing a chunk of his hands.
Bash Brothers: Kouji and Boss (when they were not fighting), Kouji and Tetsuya (when they were not arguing) and Kouji and Duke.
Batman Gambit: Kouji used several throughout the whole trilogy, often mixing them with Crazy Enough to Work. For example, in one chapter a Mechanical Beast -Kirma K5- sliced a chunk of one Mazinger-Z's wing during an aerial battle. Kouji could not balance his Humongous Mecha and he fell towards the ground. Then he goaded Kirma into attacking him again, and positioned Mazinger so his foe's Sinister Scythe sliced a chunk of the another wing. Now the Mazinger wings were the same length again, and his enemy was nearby, he could balance Mazinger back and grab Kirma. As he was beating the crap out of the Robeast he gloated it should have let him drop.
Prof. Yumi -and later Prof. Kenzo Kabuto- also used the Batman Gambit fairly often.
Beam-O-War: Sometimes Mazinger Z and a Mechanical Beast engaged in this, and usually Kouji used Mazinger's Breast Fire to couterattack their energy beams or waves. Some examples happened in episode 11 (against Brighton J2) and episode 30 (against Brutus M3).
Becoming the Mask: Erika. She was a android built by Dr. Hell. However, she suffered from amnesia and had forgotten her origins. She genuinely believed she was a normal girl, and when she was told her true nature, she rejected it. And the end she helped Kouji and she died cause it.
Beehive Barrier: The Photonic Research Institute uses a energy barrier to protect the facility when under attack.
Beneath the Earth: Not surprisingly, Mazinger Z introduced this trope in Humongous Mecha anime. The Mykene were a civilization lived and thrived in the Greek island of Bardos millennia ago, using mechanical giantsblast fire from their chests to protecting their land from invaders. 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.
Berserk Button: Kouji has several of them: insulting his grandfather, hurting Sayaka, harming innocents... Sayaka also gets easily mad when someone mocks her skills or makes Stay in the Kitchen statements directed to her (needless to say, Kouji pressed her Berserk Button constantly).
And in Shin Mazinger, when Boss and his goons insulted Kouji's grandfather one too many times, he promptly beat the ever-loving crap out of Boss, and would have seriously hurt him if Sayaka hadn't interrupted to tell Kouji that his grandfather was in real danger.
And in the Shin Mazinger Zero manga, you do not try and harm Sayaka. Otherwise, Kouji... will not be nice to you.
Beta Test Baddie: Dr. Hell has shades of this. Part of his animosity and resentment towards Dr. Kabuto comes from the fact he thinks Juuzo surpassed him, rendered him obsolete and took all away him when they were younger. All of it contributed to the breakdown turned him into a Mad Scientist. And in the third episode, after his first batch of Mechanical Beasts were crushed by Mazinger-Z, Hell got a Villainous BSOD due to after fifty years, Juuzo Kabuto STILL could surpass easily whatever Hell did.
Bigger Bad: The Emperor of Darkness -who fits the bill like God of Evil-. The Humongous MechaBig Bad Dr. Hell found were ancient -and severely outdated- weapons of his army. During the first series he did not directly interfere with the plot, and he remained in his underground empire, watching the war between Kouji Kabuto and Dr. Hell as one of his underlyings schemed to bring both of them down. After causing the end of Dr. Hell's army and Mazinger-Z he became Big Bad of the next series.
Big Damn Heroes: Kouji -and Sayaka, and even Boss- pulled this off sometimes. However, the most memorable moment happened in the final episode (and its extended movie version) when a new enemy army appears and proceed to completely overwhelm Kouji. As the Mazinger barely holds itself even a tiny bit together, the Great Mazinger shows up just before the final blow is struck and proceeds to absolutely dominate the new foes. Also something he's fond of doing in remakes, often with a nice big THUNDER BREAK to blast any number of enemies ready to swarm his allies. Also some really nice descending from the clouds shots.
The Big Damn Kiss: In Mazinger-Z vs Great General of Darkness, Kouji is going to sortie with Mazinger-Z to fight a battle he knows he can not win, and thinking he'll die. Sayaka stops him to give him his little brother's birthday gift, and both stare into each other's eyes for a long while... and then Kouji turns around and leaves. However, in the manga version of that moment, though, they DO kiss. The pannel itself featured them floating in a void, and flower petals falling around them.
Big Creepy-Crawlies: Several Kikaiju (such like Winder A2 or Megaron P1 and its "brothers") resemble slightly humanoid insects.
Blackmail Is Such an Ugly Word: Subverted in an episode. Baron Ashura hijacked a plane and threatened Professor Yumi with killing all passengers if he didn't hand over the plans for the Jet Scrander. Yumi protested that was theft and blackmail. Ashura languidly replied: "OF COURSE it is. What else did you expect from me?"
Blade Below the Shoulder: Mazinger-Z belongs to the second kind (permanently-attached blade). In the last season the mecha got equipped with the "Iron Cutter", two retractable blades stored in each arm. Often he used them in combination with its Rocket Punch to slice enemies from far. On the other hand, several Mechanical Beasts belonged to the third kind (blade replaces hand or arm). For example, Brutus-M3 had a scimitar-like blade replacing one of its arms.
As mazin sounds like majin (demon god) this may explain why Mazinger is translated as Tall Evil God.
Crabstick. Asia directs the beast king armies of Dr. Hill with its Crabstick.
Blow You Away: Mazinger-Z's Rust Tornado. Also, Stronger T4 and Blowgun P1 were equiped with weapons generated powerful currents of wind.
Body Horror: The Iron Masks (what lies beneath their helmets is not pretty), Viscount Pygman, the Kedora, a lot of Mykene Monsters... Given that this is a work of the creator ofDevilman, it was to be expected.
Blue and Orange Morality: Minerva-X is a sentient giant robot specifically created to be Mazinger-Z's Battle Couple. Despite -or maybe because- she was created by humans, several of her personality traits -mainly her conception of what love is- are completely bizarre. Because she was created to be Mazinger's partner in battle, she is in love with Mazinger in spite of she knows it is a machine and it is not sentient. She also treats the pilot of a Humongous Mecha like if it was another part of the mecha (presumably, the brain). This is expanded on Shin Mazinger Zero, where she (transformed into a Robot Girl) teases Sayaka because she saw Aphrodite (Sayaka's Fem Bot) fighting alongside Mazinger and got jealous, got... all bothered when she was inside Mazinger's cockpit, and she told she loved Kouji... but she loved even more Kouji piloting the Hover Pilder, and she loved above all Kouji on the Pilder piloting Mazinger. Usually Kouji and Sayaka only hake their heads and accept her like she is.
Sayaka: How... unique...
Book Ends: Episode 47 starts and ends with the same scene: Ashura and Brocken clashing blades as insulting each other. The only difference is in the first scene Dr. Hell broke the fight, and in the last scene he is trying and ignoring them as he has dinner (groaning about being Surrounded by Idiots).
Brain in a Jar: The Kedora. Ken Ishikawa one-shot "The Relic of Evil" revealed that the Mykene controlled his Robeast by grafting the brain of a soldier taught to destroy all no 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.
Brainwashed and Crazy: The Hero Kouji Kabuto was brainwashed by Viscount Pygman, and later by the Vegans in the UFO Robo GrendizerGo Nagai manga, the UFO Robot Grendizer tai Great Mazinger movie and Super Robot Wars MX in Chapter 10. Professors Morimori, Sewashi and Nossori also were brainwashed by Baron Ashura into one of the earlier episodes of the original anime series. AND in another episode three workers of the Institute were brainwashed into piloting several Mechanical Beasts. AND then you have the Iron Masks...
Breaking the Fourth Wall: The original manga penned by Go Nagai broke the fourth wall several times. In one of the first episodes Kouji gets forced to kill a Mook in self-defense and he suffers s Heroic BSOD thinking he is a murderer... until another character calms him down stating he was only defending himself and he is the main character and The Hero, so he did no wrong. And in this page Count Brocken complains Kouji is a Combat Pragmatist and yells the main character should not fight dirty and the fans will cry. Kouji was not impressed.
Breath Weapon: Rust Hurricane. Mazinger blows a jet of particle-charged wind from its mouth grill that corrodes the enemy into nothingness. Many Mechanical Beasts also had breath-based attacks, usually expelling out fire, acid or even poison.
In that same episode, Mitsuo, the bullied kid, later decided he would show them what being picked on by somebody bigger than you feels like, when an unknown lady showed up all of sudden and offered him borrowing her Humongous Mecha to take revenge (and he agreed. Oh, my God) Of course, that went so well how you would expect.
Calvin Ball: Parodied with Brockenball. It vaguely resembles soccer, but the only established rule is everyone wins. Except the ball. Which is Count Brocken's head. Kouji and his friends played in the original manga and Shin Mazinger when they managed capture it. They found it very funny, but Brocken found it not funny at all.
Canine Companion: Saijyo -a secondary character appeared in episode 26- and his female dog, Norako. He was an orphan, homeless boy, and she was her only friend. He was fiercely protective of her.
Cargo Ship: A mind-screwing example, overlapping with Robo Ship. Minerva-X was a Fem Bot was programmed to be Mazinger-Z's Battle Couple. So she was in love with it. However, she ALSO was a Humongous Mecha, only unlike Mazinger she was sentient, had her own mind and could feel, think and act on her own. Sayaka declaring only HER Fem Bot Aphrodite-A was Mazinger-Z's true Battle Couple did not help matters...
Robo Ship: Mazinger-Z and Aphrodite A (and later Diana-A). Also, Mazinger-Z and Minerva-X. Minerva considered matter-of-fact she was Mazinger's partner; however, Sayaka insisted ONLY Aphrodite-A was true's Mazinger partner.
Character Development: It was not huge but it was there. For example, Kouji's sexism diluded somewhat through the episodes. At the beginning, Kouji flatly refuses Aphrodite gets modified into a full-fldged battle robot, declaring he does not need aid, and stating -to Sayaka's face- girls should not fight (Predictably, Sayaka was not amused by this). Several dozens of episodes later, Aphrodite A is utterly destroyed in battle, Sayaka nearly loses it (see Heroic BSOD example), and a new robot is built for her. Kouji asks the professors endowing it with weapons.
Charles Atlas Superpower: Kouji was a physically average teenager in the original series, but in Shin Mazinger Zero he performs physical feats should be not posible, possibly due to the constant time travel is somehow heightening his capabilities. He does not seem being initially aware of it, though. In the second timeline we see he destroys one robot with one single punch and he panics wondering if he is some kind of monster. In the third timeline he easily dodges the attacks of the Gamia sisters and takes down one of them despite of they are several times faster and more agiler than a human being (like an amazed Minerva notes).
Chekhov's Volcano: The Photon Atomic Research Institute is located on the base of Mount Fuji. And unlike other shows, this series remembers it IS a volcano. Cue battles over or around the crater, the villains plotting set off an eruption in one episode and dunking The Hero and his Humongous Mecha in the volcano in another one.
Classical Mythology: It has an increasingly importance in the series. Dr. Hell finding several Humongous Mecha in the underground mazes of a Greek island has its basis on the Greek legend of Talos, the giant man of bronze 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: Several climatic battles happened next to volcanoes and lava pools. In episode 25 Kouji fought Aeros B2 and B3 next to Mount Fuji's crater, and lava bubbled and spilled out of the pool as they brawled, threatening with engulfing them. In one manga chapter penned by Gosaku Ota, Kouji and Holzon V3 battle took place into the crater of Mount Fuji, with the sheer walls of the volcano as background, toxic fumes rising and swirling around them and magma sizzling and churning under their feet. And then you have the episode where Mazinger-Z got dunked in lava...
Clingy Jealous Girl: Sayaka, sometimes. The most egregious example, though, is "Minerva X", a Sentient Mecha that loves Mazinger Z and is openly jealous of Sayaka's Aphrodite A.
It happened to Sayaka whenever a beautiful girl hang around Kouji: Hitomi, Erika, Misato...
Clothing Damage: It happened to Sayaka in the original manga sometimes (too many times for her liking). Given that it was created by the man introduced Fanservice in anime, it is not surprising. In one chapter, several female robots with blades replacing her arms sliced her dress to ribbons, without actually cutting her flesh or underwear.
Colonel Badass: Commander Badass, in this case: Great General of Darkness/Ankoku Daishogun, The Dragon of the Emperor of Darkness and commander of the seven armies of the Mykene Empire. He wields a BFS, sports a Badass Cape and a Badass Beard, and he can kick the butt of nearly any Humongous Mecha invented by Go Nagai. He led the army of Mykene Empire, personally or delegating on his generals, and he was A Father to His Men considered unforgivable default intelligence costed the lives of his troops. He fought Great Mazinger because he knew he could win, slicing it with his blade mercilessly as he laughed its attacks off. And he fought Mazinkaiser quite evenly.
Colossus Climb: An interesting example in episode 14 because it is an instance of a villain making this to one of his own monsters. To destroy a Mechanical Beast that Dr. Hell had deemed useless, several Iron Masks climbed up the several-meter-tall giant robot and planted a bomb in its body.
Combat Pragmatist: Koji, like you wouldn't believe. In his first fight, in which he had just received Mazinger, he completely abused Mazinger was overpowered compared with the Beasts to survive. During his second battle, he is not above of tricking his opponent in believing that he has given up the fight. And he does this several time during the course of the series.
Combining Mecha: Mazinger-Z is the first example -not surprise here- of this trope in Humongous Mecha anime, being of the Mecha Expansion Pack Augment kind: the robot is powered by dropping a small aircraft (the Hover Pilder) onto its head. And then it is combined with a Jet Pack to allow it fly.
Companion Cube: Several times the characters talked to or about Mazinger-Z and Aphrodite A like if they were sentient beings. Sayaka actually had a Heroic BSOD when Aphrodite A was destroyed. She even hallucinated Aphrodite was calling her. And then you have Minerva-X, an actual sentient Fem Bot and Humongous Mecha could act, think and feel on her own and was programmed to be Mazinger-Z's Battle Couple, and considered Mazinger was meant to be HER Companion Cube.
Context-Sensitive Button : Inverted example. Mazinger's cockpit was full with buttons and levers, and it is unclear what did what. Sometimes Kouji pressed completely different buttons to activate the same weapon. At least when Kouji started the Hover Pilder and took off it was consistent.
It was inverted AND deconstructed. Even although it is unclear every button and lever's function, EVERY ONE has a very specific function, and you can NOT simply press a random button and expecting Mazinger Z does whatever you want in the time. The first time Kouji activated Mazinger in the original manga, he nearly demolished one half city because he kept punching random buttons as trying figuring out how handling the damned thing. The same thing happened in the anime series, with the variation of it did not happen in one city. Even so, Kouji nearly got his little brother killed.
Conveniently an Orphan: Kouji and Shiro's parents died on a laboratory accident but in reality only their mother died. Sayaka has also lost her mother.
Convenient Coma: In Mazinger-Z versus Great General of Darkness, Shiro got badly injured and fell into a coma when the ceiling of the room he was in collapsed. He needed an urgent blood transfusion to save his life, and since blood supply was low (what with giant monsters obliterating major cities), Kouji demanded they used his own blood, in spite of he was hurt. Kouji spent the whole night by his brother's side, not knowing if he would live to see another day. Fortunately, Shiro came out of his coma the next day.
Convection Schmonvection: Many battles happened around volcanoes, near volcanoes or IN volcanoes, and at least once The Hero Kouji was dunked in lava. Since Kouji always remained inside Mazinger-Z, his Humongous Mecha provided protection from extreme heat, toxic fumes and other dangers, but in the episode where Mazinger-Z took an unwilling magma dive it was stated not even Mazinger-Z's armor and heat-insulation could endure THAT for long, and Kouji eventually would die of burning, dehydration or asphyxia. The sequels -Great Mazinger, UFO Robo Grendizer- and reimaginations Mazinkaiser played with the trope as well.
Converse with the Unconscious: Done twice (and subverted in one of them) in episode 52. After Kouji and Sayaka have a serious fight (they fight the whole time, but this time was worse than usual), Sayaka refuses to help Kouji to fight, and he gets badly injured. A grief-stricken Sayaka takes care of him in the hospital, talking to him while he is comatose. Later Kouji gets badly injured again and he falls unconscious in the battlefield. Sayaka is cradling his body, crying, begging him not dying and doing an Anguished Declaration of Love... when he opens his eyes and he calmly states he is not getting married to a tomboy.
Played straight in a chapter of the Gosaku Ota manga. Sayaka is unconscious and Boss by her talks to her, before finally leaving for battle, stating that dying like an hero is all what he can do for her.
Also played straight in the Mazinger-Z versus Great General of Darkness movie. Shiro gets hurt cause a ceiling collapsing onto him, and falls into a coma. He needs a blood transfusion and Kouji insists on them using his blood. As the medics are performing the transfusion, Kouji talks to his comatous little brother, reassuring him everything will work fine.
Cool Airship: Guru, Count Brocken's aerial fortress. It appears for first time at the episode 40.
Energer Z, the "prototype" design of Mazinger, was controlled by a motorcycle driven into the head; for the final version Nagai replaced it with the Hover Pilder because he was concerned the bike would look like a rip-off of Kamen Rider.
Cool Helmet: Kouji and Sayaka wear one. Kouji began wearing it (along his Latex Space Suit) after his first battles since his head got hit several times.
Cool Old Guy: Dr. Juzo Kabuto. He escaped alive from two Hell's assassination attempts (they were two in the Gosaku Ota manga). He built the eighteen-meter-tall, One-Man ArmyHumongous Mecha was the last hope of humanity. He saved his son's life, turning him into a cyborg. When Ashura blew up his mansion, he got half-buried under several metal rafts, but in spite of he was moribund and trapped in an underground basement, he managed surviving until his grandsons showed up and he could hand Mazinger over to Kouji. And in the manga and Shin Mazinger he overlaps this with Crazy Awesome.
Cool Ship: Salude and Bood, Baron Ashura's submarine fortresses.
Could Have Avoided This Plot: In an episode Kouji has a conflict with a young homeless boy named Saijyo because his dog was stealing Kouji's little brother's chickens. That conflict -that was exploited for The Dragon to attack Kouji- could have been avoided if only Saijyo would have mentioned his dog stole food to feed her puppies.
Crazy Enough to Work: Kouji's plans CAN be carefully and throughtfully planned strategies, but many times his plans are an Indy Ploy or... this. One example happened in episode 32: Mazinger Z got the crap beaten out of it by Gelbros J3, a flying, three-headed dragon-looking Mechanical Beast. Mazinger could not fly -yet-, so Kouji could not fight back. His plan was... equiping Aphrodite A with even bigger Torpedo Tits. During the battle Sayaka shot them, Mazinger latched on the giant missiles and was propelled it skywards, where Kouji was capable to reach the Robeast and shoot it down.
Crazy-Prepared: In one episode, an enemy was unceasingly shooting missiles at the Hover Pilder to preventing Kouji from docking with Mazinger. Kouji pressed a button, and his vehicle let go a trail of smoke to make the enemy believing he had been shot down and having him stopping to shoot as he docked.
Crippling Overspecialization: Several Mechanical Beasts had a fighting style entirely based on the weapon or device they were equipped with, and when they lost it, the battle was finished shortly after (even though they usually tried to put up a good fight). There are several good examples: Jinray S1 (episode 24) best weapon was its amazing flight speed (Match 5!) that it used to dive at its enemy, striking it with lightning bolts and missiles and fleeing away. Since it could hit him and and run away before he could even spot it, Kouji got a very hard time... until he blew up one of its rockets. Unable to perform its hit-and-run tactics, Jinray was helpless; Holzon V3 (Episode 17) was armed with huge drills to burrow underground and set off earthquakes, making it deadly... unless you forced it to return to surface, where it was a crappy fighter; Kajimofu T7 (episode 48) combined both its palm blasts and its missile launcher to hit its adversary. It was a very efective, destructive tactic... but when Sayaka and Boss ripped its arms off, the battle was over because its missile launcher was not strong enough on its own.
Crucified Hero Shot: Both Kouji and Mazinger are subjected to this several times in the course of the series. So did Shiro, Boss, Nuke and Much. Ashura seemed to love this Trope. Also, Devilman himself in the movie Mazinger vs Devilman.
Cry for the Devil: Neither the original manga penned by Go Nagai nor the anime series delved in the past and motivations of the villains. It was the manga penned by Gosaku Ota and published simultaneously with the tv show finally revealed what they were. In one of the last chapters, as Dr. Hell is making preparations for the Final Battle, Dr. Hell begins to narrate what his early life was like. We learn during the flashback that he was born in a very poor family. His mother never wanted to have a child, constantly stated his existence was a bother for her and beat him constantly as his father did nothing. No child wanted to play with him because he looked ugly and weird. Looking for a way out of it he turned to the books. He became very intelligent, began to get excellent grades in school... and then his teachers accused him from cheating and several of his classmates bullied him. He grew up without friends until he got in college, when he befriended someone who appreciated his intelligence and he fell in love with an exchange student. Shortly after he found out they were a couple and his frayed mind was already so paranoid he thought they were plotting against him to backstab him. After another unpleasant incident where he got beaten by making a good deed -a little girl slipped in front of him and he caught her, avoiding she hit the ground and got hurt. It was a well-meaning, innocent act. However her parents thought he was molesting her, and her father pummeled him- his mind finally snapped out and he decided Humans Are Bastards and one day he would wipe the world off idiots and everyone would have to kneel before him. You can tell in that right moment, Dr. Hell had been born.
Cut Lex Luthor a Check: Dr. Hell is wealthy enough to build dozens of giant, humanoids war machines, Doomsday weapons, squad of cyborgs, several HQ, aircrafts, submarines... It was kind of justified in the Ota's manga when Dr. Hell revealed shortly after finding the old Mykene's mechanical warriors, Count Brocken took over several ancient European Mafia in order to earn cash for Hell.
Cyborg: All villains -except Dr. Hell- were cyborgs: Baron Ashura, Count Brocken, their Mooks... All of them -except by Archduke Gorgon- were created by Hell himself. Usually he fabricated his cyborgs by modifying corpses, replacing damaged parts with artificial limbs or organs and implanting cybernetic components in their brains to create obedient, brainwashed slaves (and there was at least one scene in one of the manga versions where Baron Ashura killed many people off, as gloating they would be transformed into cyborgs and turned into his/her slaves. Now you know what happened to all people died when a Mechanical Beast attacked). It looked like this. However, in at least one instance he saved the life of the subject -Count Brocken- by turning him into a cyborg. Other cyborg characters were Kenzo Kabuto and in the Gosaku Ota manga Kouji Kabuto himself was turned into one by the end of the series.
