Japan creates an artificial black hole device to trap Godzilla forever, but a test of the device creates new foes for Godzilla, car-sized dragonflies called meganula and their queen, Megaguirus.
Although they do not look alike, the Meganuron (a.k.a Meganulon) in this movie is based on the Meganurons that attack the villagers in the Toho monster movie classic, Rodan (1956).
When Megaguirus shows itself for the first time, the strings holding it up, and the strings its flying on are clearly visible.
A second ending begins at the end of the closing credits: At school, the little boy Jun had finished his bug collection, and his teacher tells him to put it back in his lab. Once he does just that, an earthquake shakes the school, and looking through the window in the school lab, Jun hears a familiar monster roar!
