Metal virus

After Eggman lost his memory, Dr. Starline made him recover it and Eggman decided to create a biological weapon known as the Metal Virus, which was made so that all living beings, including trees and plants, were under his control, but Eggman did not count on the fact that the Virus would get out of control and everything would get out of hand, causing a true apocalypse where the future does not look very promising.
