Dr. Kensaku Ijuin
- Dr. Kensaku Ijuin: I know Micro-oxygen and it doesn't have that kind of power.
- Army General: So what does?
- Dr. Kensaku Ijuin: An Oxygen Destroyer! It can destroy everything and everybody. Its power is that awesome. Destroyer!
- Army General: Destroyer?
- Dr. Kensaku Ijuin: Godzilla's gone. He's turned Tokyo into a ghost city.
- Yukari Yamane: It looks like we've paid for it at the end.
- Dr. Kensaku Ijuin: Paid for what?
- Yukari Yamane: All of it. All that stupid use of nuclear energy.
- Dr. Kensaku Ijuin: First you come and see me to warn me not to make an Oxygen Destroyer... now you want me to make one?
- Kenichi Yamane: It's the only way Godzilla can be destroyed now! Every other means has failed! You're the only one who can do it!
- Dr. Kensaku Ijuin: I said I could make one, but I didn't say it was going to be easy, did I? Besides...
- Yukari Yamane: Besides?
- Dr. Kensaku Ijuin: I made an analysis of the surrounding soil. I've seen the effect the Oxygen Destroyer had on it. If it had have been used on the ground, it's quite obvious that Tokyo would've become a cemetery.
