From the introduction: They are primeval forces of nature, both Terran and alien, walking out of the sea, the earth or the sky to wreak havoc on humanity - DAIKAIJU! (Literally, giant monsters.) Awakened by atomic tests or unscrupulous geniuses meddling with what they shouldn’t, they cause wanton destruction and fight each other, often with strangely familiar wrestling moves - DAIKAIJU! Tremble in fear! Or better yet, run. Or perhaps... fight back? Err... DAIKAIJU!
