Gamera vs. Barugon

大怪獣決闘 ガメラ対バルゴン

Also known as Gamera Strikes Again, War of the Monsters, Attenzione! arrivano i mostri, Gamera gegen Barugon - Frankensteins Drache aus dem Dschungel, Dragonwars - Krieg der Monster

“Gamera burns the streets of Osaka in an instant! Barugon freezes Osaka Castle with a single gust! An underwater clash at Lake Biwa!”

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.
