- Dr. Shiragami: Godzilla and Biollante aren't monsters. It's the unscrupulous scientists who create them that are monsters.
- Kazuhito Kirishima: If they play around with cells, genetic engineers might well create their own Chimera - a new life form, totally alien, totally different to what God intended for Earth. Frightening, don't you think?
- Kazuhito Kirishima: [to Dr. Shiragami] So you did do it. You amalgamated one of Godzilla's cells together with the plant's cells. Are you proud of this? What kind science do you call this?
- Dr. Shiragami: I just wonder. Did Godzilla come all this way to see Biollante because it knew they were made from the same cells?
- Asuka Okouchi: Yes, it's possible. After all, they're from the same family.
- Dr. Shiragami: More than just the same family. They are both made from the same cells. They're identical, the same thing. Not brother and sister; they're both the same creature.
- Kazuhito Kirishima: Godzilla's gone to the sea. Biollante to the sky.
- Asuka Okouchi: And this lucky couple is going to America.
- Kazuhito Kirishima: A nice thought, but I've canceled America.
- Asuka Okouchi: Why's that?
- Kazuhito Kirishima: 'Cause wherever you go, people are the same. There's good and there's bad in every country.
- Asuka Okouchi: Then were will you go?
- Kazuhito Kirishima: Well, first of all... to bed, I should think. I haven't slept in ages.
- Asuka Okouchi: Got room for me?
- Kazuhito Kirishima: Do you snore?
- Asuka Okouchi: Nonstop.
- General Hyodo: What is this, psychokinesis? Whatever it is, it's just in the mind. We can't expect that girl to defeat Godzilla. It's too ridiculous.
- Major Sho Kuroki: Even if she is a girl, she's a great help to us. She could even delay Godzilla's landing in Osaka with a little luck. I trust her ability in ESP.
- Lieutenant Goro Gondo: [to Godzilla] All this intravenous stuff is no good for you. Stick to smoking.
