The Eye of Darkness was a villain from the cartoon series "Mummies Alive!".

A horrific monster trapped inside a mirror, no one knows his exact origin but every 3500 years, when the planets align, he seeks the soul of a Pharaoh so he can exchange himself with the spirit to free himself from the mirror. The Pharaoh's soul would then be lost until the planets realign in 3500 more years. Once unleashed, no power on earth would be able to stop him. Only the one who sets the spell in motion can stop him. The Eye of Darkness would inevitably awaken and cause chaos in the modern era before being defeated by the heroes of the show.
