"[to Dr. Emma Russell] Listen...While you were sitting comfortably in some laboratory, we've been fighting, for decades in one dirty war after another. I've seen human nature firsthand, and I'm here to tell you that it doesn't get any better. It just gets worse. So I'm sorry that Monster Zero isn't exactly what we were expecting. But we opened Pandora's box, and there's no closing it now."

"Listen to me: They'll think it's one of them. You use the wrong frequency on one of them and you're gonna be responsible for a thousand San Franciscos."

"[Rodan is bellowing and they just found out Ghidorah is heading towards him] Serizawa, it's not a coincidence that Monster Zero thing is heading here. He's reacting to Big Bird's cries. That means he's either coming for food, a fight, or…something more intimate."

"The mass extinction we feared has already begun. And we are the cause. We are the infection. But like all living organisms, the Earth unleashed a fever to fight this infection. Its original and rightful rulers, the Titans. They are part of the Earth's natural defense system. A way to protect the planet, to maintain its balance. But if governments are allowed to contain them, destroy them, or use them for war, the human infection will only continue to spread. And with our lifetime, our planet will perish, and so will we. Unless we restore balance."

"What we are witnessing here, senators, is the return of an ancient and forgotten super-species. Godzilla, the MUTOs, Kong...We believe that these 'Titans' and others like them provide an essential balance to our world. And while some may pose a threat, Monarch is uniquely prepared to determine which of these Titans are here to threaten us, and which of these Titans are here to protect us."

"Mark, we know you're hurting. But if we find the ORCA we'll find your family. I promise."

"Containment team stand down, I repeat stand down! You are scaring her!"

"As you know, at approximately oh seven hundred hours, our containment site, in China's Yunnan rainforest was raided. The specimen, code name Mothra, escaped, only to cocoon itself later under a nearby waterfall. While Dr. Emma Russell, and her daughter Madison were taken hostage. This - is the man responsible. Alan Jonah. A former British Army colonel turned eco-terrorist, obsessed with restoring the natural order. And to fund his operations he began trafficking in a new and dangerous market: Titan DNA."

"Millie Bobby Brown — Madison"

"[final words, in Japanese] Goodbye… old friend."

"I admire all forms of life."

"Just like how a forest fire replenishes the soil or how a volcano creates new land, we have seen signs that these creatures will do the same. San Francisco, Las Vegas, wherever the Titans go, life follows, triggered by their radiation."

"Nature always has a way to balance itself. The only question is, what part will we play?"

"[angrily] This is a dangerous path! You are meddling with forces beyond our comprehension, gambling with the lives of billions!"

"Ken Watanabe — Serizawa"

"This is Godzilla’s world. We just live in it."

"Sometimes, the only way to heal our wounds is to make peace with the demons who created them."

"Bradley Whitford — Rick"

"Gojira is not only living proof that coexistence is possible. He is…the key to it."

"Elizabeth Faith Ludlow — First Lieutenant Griffin"

"Tyler Crumley — Andrew"

"T. J. Storm — Godzilla (motion-capture)"
