Operation Duplicate

Operation Duplicate is an event that appears in the anime series Sonic X. It refers to the overall grand plan of the Metarex to fill the universe with nothing but plant life while killing all animals.

Metarex Saga
Operation Duplicate involves creating fake Chaos Emeralds, with the power of the originals in order to use as mediums of light and power in order spread vegetation across all planets. The plan also involves using chaos energy to mutate Planet Eggs, growing them to unusual sizes, presumably to increase their power.

The plan began once the Metarex managed to get their hands on the Chaos Emeralds, and soon began making fake copies of them, spreading them across various planets in order for them to act as mediums for vegetation to grow once Final Mova began spreading its energy waves across the universe.
