When the threat of Godzilla returns to Japan, scientists develop the first man-made black hole in an attempt to trap the monster. During a test of the new weapon, an insect caught in the black hole mutates into Meganula and spawns a host of giant dragonflies. Their queen is Megaguirus - a 50 metre flying menace set to kill Godzilla. In the skies and in the sewers - will mankind survive this clash of the prehistoric titans?© 2000 Toho Co., Ltd.
