Kouji: "Grandpa's murder... All the people who have been hurt... Japan's peace trampled... All because of Dr. Hell... This time, for sure... This time, I'll destroy Dr. Hell for good!"
Dr. Hell: "I shall crush Japan in merely ten days! And the world will witness the true power of Dr. Hell!"
Sayaka:: "Kouji. What. Have. You. Done. To. Aphrodite."
Kouji: "It was about time Aphrodite got a breast enlargement."
Sayaka: "You could not have it done without me!"
Kouji: "I did not need your help!"
Sayaka: "Yes, right! It is because that YOU asked me helping you, right?" [slapping him] "Baka!"
Kouji: "How you dare to hit me!"
Shiro [as fortune-telling]: "It is funny. The cards tell they are destined to be together forever."
Kouji: "There's no choice but for me to go and take it back!"
Sayaka: "But you don't even know what the enemy is...!"
Kouji: "I'll find out along the way!"
Sayaka: "Hurry, get Mazinger! I'll deal with things here! Return as fast as you can before they get me!"
Baron Ashura:"I won't let you get away with this...! I'll smash Aphrodite A to tiny pieces!"
Kouji: "Wait for me, Sayaka! I'll get in Mazinger and come back as the superman, Kouji Kabuto!"
Count Brocken:"Damn you! How dare the righteous protagonist do something so dirty! You sure about this? The fans will cry, you know´."
Kouji:"Shut up! Take it like a man! Don't try play innocent with me!"
Pygman: "What a show-off."
Gorgon: "What was that? Would you care to repeat it?"
Pygman: "I’ll repeat it as many times as you want!"
Kouji: My answer? It is still the same. I am not going to take part in your criminal plans.
Baron Ashura: Criminal plans...? But what...? How I can make you understand? Get this through your head! Why distinguish between good and evil? Who decided that? Humans! They established that! Because they are weak! They are not even capable to protect themselves! Those cowards spend the whole time chattering... about peace and justice! But the real world is very different! Since prehistoric times, the weak and unfit has succumbed to the will of the strong, and the strong has survived! What is good or evil about that? The unfit are defeated! It is so simple! Might makes right! If you are not strong, you do not survive! That is the only rule in this planet!
Kouji: If I understood what you were saying before... your brain was mechanized because an accident! You were human but you died! And now with that mechanical brain, someone's controlling you.
Iron Mask: Yes, That's right. It's splendid! I don't consider myself necessary. We carry out all our orders perfectly. Death is what worries you. It'll be easy! I know you're worried! So, please, consider it.
Kouji: Even if you don't need your brain... I will not consider it. Even if it is easy, you hear?! You idiot, such a thing wouldn't even be human!

— Dr. Juuzo Kabuto, Mazinger Z, "Episode 38"
Are there really a lot of people named Dr. Hell? You could not have a name that shouted "Hey look, I'm evil" louder if you tried.
Kouji: Buttons and handles strewn all over the instrument panel at random? This couldn't be more confusing!
(Shortly after having trashed his home)
Kouji: I don't understand how these controls work! I don't understand! I command you to stop! (while punching through another house) Waaarhgh! Stop it, Mazinger!
(After having stomped on several buildings and while leading towards a road)
Kouji: Maybe this one will turn him right? N-No, wait... I-if I make a mistake, then... Please, Mazinger!
(after having smashed the road and crushed and thrown away several cars)
Kouji: You can't do that, Mazinger! Kouji, you have to hurry it up and figure this thing out! I, Kouji, am your pilot, Mazinger-Z, and you do as I say, and I said, stop!
(A while after Sayaka managed stopping him after he had smashed down more buildings -one of them a child school- and left a wide trail of destruction)
Kouji: Can... Can you hear me? I am Kouji Kabuto. I finally figured out which of these things was the radio! I have been trying contacting you for some while now. I'm saved! I'm really saved!
Kouji: You're the first person I've been able to talk to since I got on this robot! It's not like I've been doing all this because I wanted to! Please believe me, it's because I didn't understand! I don't know how pilot this thing! I mean... I didn't know how to move, much less stop it, but... I think I've got it figured out now, more or less.
Kouji: Suddenly, without knowing at all what I was doing, I got in and piloted this thing. Later... I stopped the robot. I was impatient. So impatient I made all this happen.
"For sure, one Mazinger-Z may be hiding no less than 5% of the total combat strength of the world's major military powers!"
Kouji: Boss! Come on, Boss, wake up!
Boss: Leave me alone. I am dead.
Kouji: Don't be stupid! Dead men can not talk!
Boss: Oh. Right. Then I'am alive! I'm alive! I love being alive!
—Mazinger Z, Episode 91
Rage. Pain. Sorrow. Every emotion. Everything coming together. Flowing to the same place... To the Demon God of Demise. Inside every wish becoming zero. At my wit's end, I can just watch.
—Minerva X, Shin Mazinger Zero, Chapter 4
This is the memory of meeting Sayaka again after ten years... Remembering... Throbbing in my heart until then... Pounding... I thought at the time... People don't think with their head, they think with their heart... Everything wasn't inside of this meeting... But. That... Disappearing... everything... everything... Disappear... ing... What is it in there? My body? Then the me that's seeing... is who? Mazinger... My rage. Sorrow. Pain. Every emotion, being swallowed by Z into one... No, becoming ZERO. Disappearing. Completely vanishing...

Count Brocken: Geh-heh-heh, that one's piloted by a girl, huh? Punishing you is gonna be SO MUCH FUN. First I'll peel off the cockpit armor, and then...
Lunamaria: Enemy of womankind!
Marguerite: Lewd men such as you deserve little mercy!
Aoi: You're the one who's gonna be punished!
Sylvia: Prepare yourself, Count Pervert!
Kallen: I'm gonna play soccer with your head!
Sara: No, no, I'm going to turn it upside down and use it as a flowerpot!
Yoko: I could use it for target practice...
Noin: No, I'll feed it to my dog.
Sumeragi: I hereby authorize all of you to carry out those actions.
Count Brocken: Wha-WHAT?! I haven't even done anything yet!

Baron Ashura: Hand over the plans right now or my soldiers will kill all passengers.
Professor Yumi: This is a robbery! And blackmail!
Baron Ashura: OF COURSE it is. What else did you expect from me?
— Mazinger Z, Episode 33
Kouji : You! I won't let you spread war into space!
Vindel Mauser: I won't let you say... that you don't know how much mankind evolved from war!
Kouji: It doesn't matter! Even if people like you exist, I'll still fight! I don't want people to suffer, like Daisuke or Maria who lost their home planet!
Vindel: Your emotions are strong! Your machine is just a result of that! You have the power to become god or devil, why deny it!?
Kouji: Gramps told me so! But, I'm the one who decides Mazinger can become a god or a devil! Kouji Kabuto! And this power... It's the power to defeat bastards like you!
Dr. Hell: …You can come out now.
Gestalt: Your obsession with Photon Power is…amusing.
Dr. Hell: This King of Hell isn’t enough to fight the Ba’al with…only with Photon Power can we survive!
Sayuri: Do you think those three clowns will even succeed?
Dr. Hell: They will live up to my expectations! I have high hopes for Baron Ashura.
Gestalt: And why the elaborate call for a showdown? If you wanted the Photon Power so badly, you could’ve taken the Photon Labs while ZEXIS were dealing with Insalaum!
Dr. Hell: You fools could never hope to understand my plans!
Sayuri: Perhaps. In any case good luck (not!) for the battle.
Gestalt: You might need it more than you think! Mwahaha!
