Gamera vs. Barugon

Directed by Shigeo Tanaka

With Kōjirō Hongō, Kyōko Enami, Yūzō Hayakawa, Takuya Fujioka and Kōji Fujiyama

Gamera escapes from his rocket enclosure and makes his way back to Earth as a giant opal from New Guinea is brought back to Japan. The opal is discovered to have been an egg that births a new monster called Barugon. The creature attacks the city of Osaka by emitting a destructive rainbow ray from his back, along with a freezing spray capable of incapacitating Gamera.
