Kenichi Yamane
- Kenichi Yamane: There's only one solution. We must kill him, the way we killed the first Godzilla.
- Miki Saegusa: You can't...!
- Kenichi Yamane: The Oxygen Destroyer.
- 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.
- Emiko Yamane: Listen to me, Ken. Dr. Serizawa destroyed all his research. There's nothing left to go on now. He didn't want his work used. In the end, he took his own life to save the world.
- Kenichi Yamane: Yeah, a waste of a good man.
- Emiko Yamane: [referring to the Oxygen Destroyer] Even if you do make one, are you sure it'll be properly used.
- Kenichi Yamane: No, I'm not so sure. But Auntie, this time the Earth is in danger! If we don't build one, then we're finished!
- Emiko Yamane: But still, I don't like it, Ken. Don't do it... whatever the reasons are.
