Aka: Meganuron, Meganulon
Attempting to remove Godzilla with a Black Hole Gun called "The Dimension Tide," the Anti-Godzilla Battle Forces cause a warp in the space-time continuum allowing for an invasion by huge insect monsters. From the egg to the 2 meter larvae (Meganuron), the creatures natural instinct is to create a hive, and they choose Shibuya to create their nest (the Meganurons first appeared in the 1956 production of RODAN).
The Meganurons soon grow into winged 5 meter long "Meganuras," and begin to drain energy from a number of sourcesâ€”all to feed their queen. By amassing a great storage of energy, they are able to birth the colossal 50 met. Guess who is their next energetic meal ?
