ORIGIN:
A sea mining company harvests large silver spheres from the bottom of the ocean, and sells them around the world foe the construction of impenetrable walls. The monster Meduzonora comes ashore, curious about the walls but cannot pass through them. Once the stars align in a specific way, the spheres all hatch at the same time, across the world, and the monster's offspring swarm the planet.
ABILITIES:
Ultra-Iron Eggs: lays eggs made of impenetrable metal
Devil's Shatter: uses front legs to cause massive traveling earthquakes
Propeller Swim: when in water, uses rear flippers to move quickly
