The heat incubates the opal actually an egg and a lizard eventually hatches. Growing to enormous size very quickly, the lizard destroys the ship and Kobe Harbor. Keisuke, having survived the cavein, awakens in the care of the villagers. He then returns to Japan with a village girl called Karen, who refers to the lizard as Barugon. Barugon wreaks havoc in Osaka with its freezing breath and prevents a retaliative missile strike with a rainbow emanation from its back. Barugon encounters Gamera and the two battle, with Gamera eventually being frozen solid.Keisuke and Karen, having arrived in Japan at that moment, then go to Onoderas home. Onodera tells Keisuke that the opal is aboard the sunken ship. Keisuke informs Onodera that the opal was Barugons egg. Onodera refuses to believe him. Keisuke also says to Onodera that he went to see his brother, but found that both his brother and his brothers wife had burned to death. Keisuke implies that Onodera was responsible, and they fight, after which, Keisuke and Karen leave him tied to a support beam in his home. The pair then travel to the Japanese defense ministry, where Karen tells them Barugon is vulnerable to water, and suggests a plan using a huge diamond to lure Barugon into a lake to drown. ........
