Craft: Trust? And just who should I be trusting? The humans that do nothing while their world falls apart? The humans that fear us, their own creations? Or the humans that try to conquer the world? We fight each other for them!? This world screams out in pain under them... Why should I trust anyone? How can you trust them? How can you fight?
Zero: I made a promise to a friend I intend to keep. To someone who believed harmony between human and Reploid as possible. I trust that friend. And I trust the humans that friend trusts...
—Craft questions Zero's ideals, after his defeat
Justice!? Freedom!? Worthless ideals! You Reploids are just machines, but you started a war a long time ago in the name of freedom! And humans! Look what they did to me! Driving me away while spouting the word "justice!" Zero, would you insist on saving them!? Controlling the Reploids is nothing! The destruction of all mankind is only fleeting! Not quite alive... Not quite dead... Forever, by my side! I'll make you suffer a fate far greater than anything ever experienced before!
—Dr. Weil's boast to Zero before their battle
I never cared about justice, and I don't ever recall calling myself a hero... I have always fought for the people I believe in. I won't hesitate... If an enemy appears in front of me... I will destroy it! [...] Ciel... Believe in me!
—Zero's last words, before the final battle with Dr. Weil
