Gamera, the Guardian of the Universe (1995)

Gamera, the Guardian of the Universe (ガメラ大怪獣空中決戦 Gamera: Daikaijū Kūchū Kessen) is the 9th entry in the Gamera film series, the second produced by Daiei Film Co. after Gamera: Super Monster and the first in Heisei period trilogy, followed by Gamera 2: Attack of Legion (1996) and Gamera 3: Revenge of Iris (1999). Unlike Shōwa period films, that were more children-oriented, the Heisei period trilogy has a dark and heroic tone. In the first film Gamera, a colossal fire-spitting and jet-flying turtle, fights against numerous giant bat-like predators known as Gyaos. The film is directed by Shusuke Kaneko, who would also direct Godzilla, Mothra and King Ghidorah: Giant Monsters All-Out Attack. The film is notable for introducing the concept of Gamera's most recurring enemy, Gyaos, becoming his arch nemesis and acts as a sort of spiritual remake of Daiei Motion Picture Company's Gamera vs. Gyaos.

Pink muzzle flashes are typical for Japanese flashpaper replica guns, widely used in filming. Why these air rifles have a muzzle flash is unknown, as combustion would be non-conducive to the tranquilizer surviving firing.
