The Eggman Empire's decal, from Sonic the Hedgehog #1.

The Eggman Empire[1] is a political body that appears in the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing. It refers to the totalitarian regime ruled by the infamous Dr. Eggman that seeks to lay claim to the entire globe. Although it has occasionally been established, the Eggman Empire has never managed to hold its ground, and merely refers to the territories Eggman has claimed and plans to claim. Its main enemies are Sonic the Hedgehog and his allies.



Some time ago, the Eggman Empire got taken over by Neo Metal Sonic after the robot gained an independent personality and overthrew Dr. Eggman. However, after Team Sonic defeated Neo Metal Sonic, Eggman regained control over his empire. He also repaired Metal Sonic and removed his rebelliousness from his coding.[2]

A while after that, the Eggman Empire went to war with the Black Arms when they invaded the world. Thanks to the empire's efforts, the heroes of the world managed to last long enough to defeat the Black Arms.[3]

The Eggman War

In the recent past, Dr. Eggman managed to expand the Eggman Empire across the majority of Sonic the Hedgehog's world after catching Sonic off-guard and imprisoning him. However, a resistance army soon formed to bring down the empire's regime and managed to free Sonic from his incarceration.[1][4] In hopes of having a superweapon on his side for the final battle, Eggman began the process of converting Metal Sonic into Neo Metal Sonic again.[2] Before Neo Metal Sonic could be completed however,[2] Sonic and the Resistance beat Eggman and broke the Eggman Empire's control over their world.[1] In the aftermath, Eggman disappeared, leaving the Eggman Empire's army directionless[1] and causing the scattered Badniks to randomly attack anyone they came across.[5]

Soon after, Neo Metal Sonic was completed. Seeing the state of the Eggman Empire, Neo decided to take it upon himself to continue the doctor's legacy by assuming Eggman's persona and lead the Eggman Empire for the doctor, his goal being to help the Eggman Empire conquer the world and then hand the control of the world over to Eggman once he found him.[2]


Neo Metal Sonic's first known move was making the Eggman Empire's scattered Badniks attack towns in a more organized manner, mainly to act as trials for Sonic.[1][4][5][6] After learning Knuckles the Echidna had abandoned his post on Angel Island, Neo Metal Sonic decided to plot a course for the island.[6]

The Fate of Dr. Eggman

Following an unforeseen encounter between Sonic, the Chaotix and his troops, Neo Metal Sonic had the Eggman Empire mobilize the Egg Fleet for a trip to Angel Island.[3][7] On his way to join the Egg Fleet though, Neo Metal Sonic had a brief encounter with Sonic, who managed to escape Neo's clutches after learning of his motives. Although Sonic had been alerted to Neo Metal Sonic's activities, Neo Metal Sonic proceeded with his master plan by invading Angel Island.[2] In no time at all, Neo Metal Sonic conquered Angel Island and seized the Master Emerald for himself.[8]

Battle For Angel Island

With Angel Island turned into a flying fortress under the control of the Egg Fleet and the Master Emerald in his possession, victory seemed all but certain for Neo Metal Sonic. However, the Resistance and their allies soon made an attempt to liberate Angel Island. Upon their arrival in a battleship, the Egg Fleet shot their vessel down. However, the heroes still made it onto Angel Island. There, most of the group worked on breaking the Egg Fleet's control over Angel Island while Sonic and Knuckles confronted Neo Metal Sonic inside his fortress on the island.[9] However, while the heroes were succesful in freeing Angel Island, Neo Metal Sonic managed to complete his plan for turning himself into Master Overlord by combing Sonic and Shadow's bio-data with the power of the Master Emerald.[10] However, Master Overlord was eventually defeated by Sonic and his allies, causing him to de-transform back into an offline Metal Sonic. With that, the Eggman Empire was left without a leader again.[11] However, in the meantime, Dr. Starline successfully managed to find Dr. Eggman and help him recover from his last defeat, allowing the doctor to take his rightful place in the Eggman Empire once again.[12]


Beginning a new plan for world domination, Eggman created the Metal Virus. Upon seeing it exhibit the ability to turn organics into metallic slaves, Eggman hastily began implementing it into the next phase of his plan.[13][14] He had Rough and Tumble face Sonic and Amy in Echo Mine but secretly equipped them with backpacks filled with Metal Virus that would swiftly turn them into Zombots. In the skirmish between the four, Sonic was infected.[15] Eggman moved on and began infecting several towns and cities with the Metal Virus in order to expand his new army.[16]

Crisis City

Eggman soon discovered that the virus had begun mutating beyond his control, which resulted in the Zombots no longer listening to his commands.[17]

The Last Minute

Eggman and Starline attempted to find working radio frequencies to control the Zombots with once again but to no avail. After Sonic had intercepted the duo, they retreated to the Faceship, where Eggman learned from Orbot that the Faceship had distributed a batch of Metal Virus down to Spiral Hill Village.[18]

Armed forces and enforcers

The Eggman Empire commands a sizable proportion of military forces. With the engineering genius of Dr. Eggman at the helm, the empire possesses disastrously destructive machines, nigh-impenetrable fortresses, diabolical robots, and tools of Eggman's own design.[1]

Foot soldiers

  • Badniks: The Eggman Empire's brand of mass-produced robot forces. They serve as the empire's main foot soldiers. Various forces of Badniks occupy various regions of the world to supplement Eggman and his lackeys. While many of the Badniks consist of robot models based on non-anthropomorphic animals, their rosters also include models with more humanoid and weaponized designs.
    • Super Badniks: Special Badniks that are more powerful and far more lethal that the regular Badniks.

Fleets and cruisers

  • Egg Fleet: The Eggman Empire's aerial assault armada.

Piloted mechs and vehicles

The Eggman Empire has a several machine units that can operate independently or with a pilot. These include:


While the Eggman Empire has rarely gained a substantial amount ground, it has still managed to build bases within certain territories that give the empire a degree of control in some parts of the world. However, its influence is kept at bay thanks to the efforts of Sonic the Hedgehog and his allies:
