During the 2010s, science fiction's immortal adversaries King Kong and Godzilla, representing our conflicts per Carl Sagan's "dream dragons" analogy, made comebacks in American cinema. The blockbuster Kaiju resurged onto the screen, depicting these protectors of an Earth plagued by mankind's hubris and folly. With Earth's future hanging in the balance, their climactic 2021 staging settled a score between the two giant monsters, resolving Toho's classic 1963 film King Kong vs. Godzilla. As formidable creatures emerging from Time's Tomb on Mother Earth, metaphorical Kong and Godzilla are considered here in light of new millennial environmentalism's stark reality. This book, nostalgic in tone, explores the meaning of Kong and Godzilla as planetary saviors--titanic protectors of a theoretical "living Earth" Gaia--defending the globe from a prehistoric plague of adversaries.
