ゴジラ対メカゴジラ
Godzilla Junior first appears in "Godzilla vs. Mechagodzilla II" as an egg. Presuming it to be a "Pteranodon" egg, a scientific team unearths it from Adona Island and ships it to Japan for study. The egg displays strange psychic properties, even imprinting itself upon the biologist Azusa Gojo, before finally hatching to reveal an infant "Godzillasaurus". When Godzilla later appears, having sought out Baby Godzilla through an unexplained psychic link, Baby Godzilla leaves with Godzilla, later settling on Birth Island.
