Lurking in the oceans around Letchi Island in the South Pacific, this giant stalked. Striking during storms, sailors often last sights were that of a mammoth crimson claw crashing down. However, Ebirah's true purpose would soon be revealed. When a boat, full of a handful of Japanese men, crashed onto an island they found the hideout of the Red Bamboo. This group was a terrorist organization intent on building an army. With the organization dabbling in radioactivity, the left over radioactive materials from their weapon development gave birth to the island's giant inhabitants. Both the Giant Condor of the sky, and Ebirah of the sea.
