ゴジラ対メカゴジラ
Long a dump for radioactive waste, Adona Island came to broader attention when a scientific team uncovered a half-buried human-sized egg and subsequently encountered Rodan and Godzilla in "Godzilla vs. Mechagodzilla II". As a consequence of the high levels of radiation on Adona, the egg, which had been of the species "Godzillasaurus", had mutated in such a way that the hatching Baby was more a baby Godzilla than a dinosaur.
