Eggperial City is a location that appears in the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing. It is Dr. Eggman's latest capital city of the Eggman Empire, built after the events of the Metal Virus plague.[1]

Eggperial City is a massive city located in the middle of an open field inside a large forest area. Curiously, the field it is situated in is divided into a geometric grid. Furthermore, Eggperial City is shaped like a giant hexagon, with a black outer wall surrounding the city on its edges. In addition, the city itself is divided into six equally sized sectors by six tall and segmented gray walls extending from the corners of Eggperial City and into the center of the city. Each of these sectors are colored differently in the following colors: red, turquoise, blue, yellow, purple and green. The insides of the city resemble as well a printed circuit board when viewed from above: there are purple roads extending outside and inside Eggperial City that are shaped likes signal traces, massive tubes resembling copper wires, and buildings and complexes resembling electronic components. Furthermore, there are various cone-shaped towers, most of which are colored in accordance to the sectors they are located in. Lastly, in the center of Eggperial City is a massive gray tower with a thick stem and a wide dome-shaped cap with four prongs and a red Eggman Empire decal painted on it. Extending from the top of it is an elaborate antennae.[2]

The central tower Eggperial City contains the city's headquarters. This room houses a throne with the logo of the Eggman Empire. It also has an escape chute leading to the Memorial Garage, where Eggman keeps his old mech machines while he is working on refurbishing them.[3]



Following the end of the Metal Virus plague, Dr. Eggman focused on rebuilding his empire, which led to the creation of Eggperial City.[1]

Imposter Syndrome and Trial by Fire

Eventually, Dr. Starline, Surge and Kit invaded Eggperial City. As the local Badniks tried defending the city from the invaders, Orbot and Cubot returned to Dr. Eggman after taking a leave of absence for a while. Eventually catching the duo sneaking into his headquarters, Eggman took no interest in where they had been and ordered them to monitor Surge and Kit, who were wrecking havoc around Eggperial City. Eggman eventually sent Metal Sonic after the duo, but Surge and Kit managed to defeat the robot. Eggman then detected Starline's presence in his server room. There, Starline uploaded an override program that gave him control of all the Badniks in the world in the world. As his own robots tried to apprehend him however, Eggman escaped through a chute to his Memorial Garage, where he chose one of his old machines to launch a counterattack with. Meanwhile, Starline was led to Eggperial City's headquarters, where he took Eggman's throne and ordered his signal to be broadcast all over Eggnet in order to assemble all the world's Badniks in Eggperial City, which he knew would lure Sonic to the city. Meanwhile, Surge and Kit plotted to betray Starline by exterminating not only Sonic and Tails, but also Starline, Eggman, all of their allies, and everything else that both the villains and heroes stood for.[3]

Following the converging Badniks, Sonic, Tails, and Belle soon discovered Eggperial City, which they eventually headed towards at super speed with Sonic's aid to investigate.[2]
