Dr. Ichiro Serizawa: "In 1954, the first time that a nuclear submarine ever reached the lower depths, it awakened something."
Vivienne Graham: "The Americans first thought that it was the Russians. The Russians thought that it was them. All those nuclear tests in the '50s...? Not tests."
Dr. Ichiro Serizawa: "They were trying to kill it. Him. An ancient alpha predator."
Vivienne Graham: "Millions of years older than mankind. From an age when the Earth was ten times more radioactive than today. This animals and others like it consumed this radiation as a food source. As the levels on the surface naturally subsided these creatures adapted to live deeper in the oceans. Furter underground. Absorbing radiation from the planet's core. The organization we work for, Monarch, was established in the wake of this discovery. A multinational coalition formed in secrecy to search for him. Study him. Learn everything we could."
Dr. Ichiro Serizawa: "We call him... Gojira."
Vivienne Graham: "The top of the primordial ecosystem. A god, for all intents and purposes."
Ford Brody: "A monster."

Vivienne Graham: "Oh, my God. Is it possible? Is it him?"
Dr. Ichiro Serizawa: "No. This is much older."
