Planet Egg of Sonic's homeworld

Planet Eggs are large gemstones of varying shape and color. Each Planet Egg embodies the life force of its home planet.

Throughout the third season of Sonic X, the Metarex are seeking the Planet Eggs as part of their plans to destroy all animal life in the galaxy so that plants may rule, but was foiled by Sonic the Hedgehog.

Removal of a Planet Egg

Once a Planet Egg is removed from its spot, the planet begins to die, which can take many different forms. On Sonic's homeworld, the plant life began to die out in the surrounding area once the Planet Egg had been extracted from Angel Island. On another occasion, the Planet Egg's harvesting turned a desert planet into a gigantic ocean. These effects were reversed after Sonic and co. recovered the Planet Egg, though they had to fight off two powerful Metarex in order to save the planet.

Another world became covered in ice when the Planet Egg was gone, a fact that greatly saddened Cosmo until the Egg was returned. Later, the gang of heroes found a world that had become overgrown by plants. Using the Planet Egg of this world, Cosmo was able to communicate with the vegetation, but it went out of control as a result.

History

A Planet Egg

Historical records on Cosmo's homeworld revealed that Dark Oak (then known as Lucas), the leader of the Metarex, had first discovered a way to use the Planet Eggs to stabilize the unnatural transformation process he and other male members of Cosmo's species were capable of. He used its power to make himself and the other males immortal, turning them into the Metarex. Because of this, the females led by Earthia left their homeworld behind, thinking that the males would be destroyed. Instead, they survived and built metal bodies to support their frail structures.

Planet Egg of the jungle planet

Dark Oak planned to use the Planet Eggs of every planet to grow stronger. For years, the Metarex stole the Planet Eggs of every planet they could reach, as part of their plan to rule the galaxy.

As a result of their own Planet Egg being stolen, Sonic and his friends boarded the Blue Typhoon and began traveling around the galaxy in an effort to stop the Metarex.

Some time later, the Blue Typhoon and Doctor Eggman arrived at a Metarex fortress. After making their way through the defensive gauntlet, they discovered a Planet Egg that had been enlarged by energy from two Chaos Emeralds. Unfortunately, a battle with the Metarex resulted in the Egg being jettisoned and lost.

When all the combatants in the conflict reached Galactic Coordinates 000, the true plan of the Metarex was revealed: to receive enough energy to conduct a special event that happens once every a thousand years. Using the Planet Eggs as a source of water and the Chaos Emeralds as a source of light, the three leaders of the Metarex, Pale Bayleaf, Black Narcissus and Dark Oak transformed into the Final Mova planned to channel the energy from a breach in space time to destroy all non-plant life in the galaxy. Fortunately, their plans were thwarted. After the Metarex were destroyed, all the Planet Eggs scattered back to their home planets in a flash of many lights.

Different Planet Eggs

No two Planet Eggs are alike, but only a few are known. The Planet Egg of Sonic's home is a pink square jewel, which is located in the forest under Angel Island. The Planet Egg of the jungle planet is a green sphere with little pillars. Its location might seem to be the middle of the jungle.

Trivia

• The Planet Egg from Sonic's homeworld resembles the shape of the original Chaos Emeralds as depicted in Sonic the Hedgehog, especially the pink colored one (discarded color in later games).
