Sonic facing off against Eggman in the Death Egg Robot.

After getting ahold of a mysterious artifact known as the Phantom Ruby, Dr. Eggman defeated and captured Sonic and conquered the majority of the planet. The Eggman Empire Fortress served as a major location belonging to the Eggman Empire. Thanks to the help of the Resistance (formed by Sonic's friends and allies and comprised of many more soldiers), other allies, and a past version of himself from an alternate reality, Sonic was freed and helped to stop Dr. Eggman's conquest and save the world from his clutches.[1][2] This ended in a confrontation between Sonic and Eggman, the latter piloting his latest Death Egg Robot in the fortress itself. Sonic was victorious, and the mad genius was defeated. (StH: #1)


The Eggman Empire Fortress is a high-tech fortification with spotlights located in the middle of a deep crater whose edges are surrounded by high walls. These walls extend into the depths of the crater, forming staircase-like levels. Rising up from the center of the crater is a massive high-tech tower with tall metallic pieces forming hoops circling around it. The fortress also has several floating platforms.

It was unnamed in the comic, but is considered tier 2 canon by this site's canon policy, as it does not contradict already established canon from tier 1.
