Minilla, also known as Minya, first appeared in Toho's Son of Godzilla in 1967 as Godzilla's adopted son on Monster Island. Designed as a smaller, friendlier kaiju to appeal to younger audiences, the character returned in several Showa era films. Online, clips of his unusual cry have been reused in Godzilla edits and minilla memes, where fans contrast his gentle sound with the much larger roars of adult kaiju, keeping the character popular long after the original films.
