Eggman Land

Eggmanland is a location that appears in the Sonic the Hedgehog comic series and its spin-offs. It is an energy refinery designed to resemble an amusement park with lethal attractions created by Dr. Eggman as part of his plan to harvest and refine the energies of Dark Gaia unleashed during the Shattered World Crisis.

History
After determining that Dark Gaia's raw power was an abundant source of energy, Dr. Eggman decided to harvest it for his own uses. Due to his own eccentricities, he decided to construct a refinery that incorporated death-trap thrill rides into its design, something that Orbot felt was a waste of time and resources. Eventually he succeeded and Eggmanland was born, and it soon began harvesting Dark Gaia's energy, the goal being that it would be used to supercharge the Death Egg.
