After a seaquake, a huge lizard-like creature walked out of the ocean and almost destroyed a fishing village in Ireland. Fortunately for the village, the same quake that brought the 65 foot monster to land has also grounded a salvage ship, the crew of which proved up to the task of capturing the beast. The monster, dubbed Gorgo, having found a taste for the land, began to make regular visits there. At the same time, governments, scientists, and even would-be world conquerors pursued Gorgo and his mother for their own ends. This led Gorgo to finding himself in a succession of dangerous situations, from battling other giant primitive monsters, to control by mad scientists, to even at one point inadvertently preventing World War III. Collects Gorgo #16-20 (December 1963-October 1964).
