The Eggman Empire (エッグマン帝国 Egguman Teikoku?), also known as Robotnik Empire, is an empire of scientists and robots in the Sonic the Hedgehog series. The Eggman Empire, as its name shows, is led by Dr. Eggman. It is the doctor's ultimate goal to have the Eggman Empire encompass the entire Earth in his quest to achieve global dominance. So far, the Eggman Empire has never actually been seen or built, and merely refers to the territories Eggman has claimed and plans to claim. Sonic Unleashed was the most recent game to feature the Eggman Empire, although Sonic Colors could possibly count.

In the world of the video game series, Eggmanland (エッグマンランド Eggumanrando?), also known as Robotnikland, is a land that Sonic the Hedgehog's nemesis, Dr. Eggman, often speaks of and are meant to serve as the captial of the Eggman Empire, from where the doctor plans to spread his rule from. In some continuities it is a land that he has already established; in others he only has plans for it.

The early cartoons and Archie Comics use the name Robotropolis (though the comics later adopted the name when an alternate version of Robotnik appeared). In most continuities, Eggmanland takes on the form of a technocratic dictatorship, with Dr. Eggman himself as the self-appointed Head of State. In general, as far as the social order of each continuity's Eggmanland spans out, robots and scientists employed by Eggman are granted greater social status than that of other Humans and Mobians.

While the Eggman Empire refers to all the areas controlled by Dr. Eggman, the capital of the Eggman Empire does not actually exist; Eggman constantly strives to establish it with various plans, several of which involve the use of Chaos Emeralds, befriending mythological deities or a combination of both.

Originally the empire has not being referenced in the first main installments of the series, as Eggman is mostly told to being after Chaos Emeralds, kidnapping Animals and turning them to his royal Badniks or building the Death Egg in original instruction manuals, although it is implied that building his empire would be the next step after completing his early operations.

In Sonic the Hedgehog CD, Dr. Ivo Robotnik temporarily succeeds in creating a complete "Eggmanland" in the future world of the Little Planet by altering the past - this dark future is mainly a bleak post-apocalyptic world with all of Robotnik's robots being broken down and the scenery rusted and deteriorating. This could either mean two things: Robotnik's desired utopia is doomed to failure or that he has no regard to whatever happens to the planet environmentally, as long as it is under his control.

Long Live For His Empire

Doctor Eggman's threat message to the world in Sonic Adventure 2.

In Japanese instruction manual of Sonic Labyrinth, Eggman is known to hint about his plans of world domination for the first time.[1] Eggman mentions about it again in Sonic Adventure as "Robotnikland", which he can build over the ruins of the Station Square after destroying it. For doing that, he released Chaos from Master Emerald and tries to collect Chaos Emeralds in order to get Chaos to its full form. In Sonic Adventure 2, the names "Eggman Empire" and "Robotnik Empire" were both used. This can be presumed as two words in the background while Eggman was broadcasting his threat. Also, in the Dark Story, a scene is called "Eggman Empire". The latter game also implies that his world domination plans, and essentially the Eggman Empire, had earlier been spawned as a result of his initial beliefs that his grandfather, Gerald Robotnik, had been unfairly tried by the government.

Occasionally there has been someone else forcefully taking Eggman's position in the Eggman Empire. In Sonic Heroes, Metal Sonic imprisoned Eggman and took control of the empire, while also taking new physical form as managing to copy several abilities to get his monstorous form.

In Shadow the Hedgehog, the Eggman Empire is one of the factions that Shadow can align himself with along with GUN and the Black Arms. When fighting for the Eggman Empire, Shadow is guided by Eggman, who communicates with him from a hovering TV-like apparatus.

While Eggman himself may not yet be able to complete Eggmanland, it was shown in Sonic Rush, that his "alter ego", Eggman Nega, has completed it. However in Sonic Rivals and its sequel, Eggman Nega disguises himself as Eggman and takes control of Eggman's empire as trying to change the world to single card with his special camera or releasing Ifrit from another dimension.


Eggmanland as seen in Sonic Unleashed.

In Sonic Unleashed, Eggmanland does exist as one of the game's stages, created through the power of Dark Gaia and looking like a twisted mixture of a carnival and a factory. In Sonic Chronicles: The Dark Brotherhood, it is shown in the cliff-hanger ending that he has finally achieved his "empire" while Sonic and company were in the Twilight Cage as a result of the time difference between the two areas.

Prior the events of Sonic Colors, Eggman has taken over numerous planets, which are populated with Wisps. Eggman uses Wisps and their powers as its energy source of mainly fueling the Mind Control Ray and Badniks as well. All these planets are connected to Dr. Eggman's Incredible Interstellar Amusement Park, which also has giant mind control ray, that originally Eggman would used to get everyone at Sonic's world under his control after getting enough of Wisp's life source. He had been close to get everyone in the Earth on his control, but due to the energy leak, the large mind control ray gets malfunctions, creates a black hole and severely destroys the Mind Control Ray and the entire amusement park itself as well.


Wherever Eggman is setting his operations, it typically displays a traditional decal. This decal is often also seen on his robotic creations, vehicles, battleships or weaponry. Also many deadly in-game obstacles and structures are known to have Eggman's decal as well. The Eggman Empire's decal is known to have the smiley face of Doctor Eggman himself, which could be also shown everywhere on his empire, if he manages to succeed with his plans.

The early known, stylistic EG logo can be found at wings and doors of Wing Fortress Zone in Sonic the Hedgehog 2, but it has also be seen at right shoulder of Grounder and brown driving seat of Egg Typhoon from Sonic Drift. More Eggman-looking decal is then seen in Sonic Adventure, depicting Dr. Eggman's classic design despite getting redesigned in the game. Eggman has another decals everywhere on his hidden pyramid base in Sonic Adventure 2. Sonic Heroes features another decal on the Eggman Fleet which is also seen in Shadow the Hedgehog as well. Since Sonic Unleashed, Eggman made simplistic decal to fit his modern appearance. The most recognized logo is seen at his Eggmanland flag in the same game. Recent decal of his empire is then used since Sonic Colors.


In other media

Sonic the Comic

In the continuity of Fleetway's Sonic the Comic, Doctor Robotnik managed to conquer all of the planet Mobius and establish a totalitarian regime when Sonic and his crew were catapulted six months into the future by the Omni-Viewer. He remained in power from Sonic the Comic #8-#100, ruling the planet first from the Special Zone's Egg Fortress and later from Citadel Robotnik in the Metropolis City Zone. Under his rule, Mobius was heavily industrialised and (deliberately) polluted. Citizens could be grabbed at any moment to be sent to the Badnik Processing Plants and Robotnik would regularly send Badniks to attack the Zones he was in charge of, just to show he could. Due to his constant targeting of the Emerald Hill Zone, the people were secretly evacuated to the Mushroom Hill Zone on the Floating Island.

In the milestone 100th issue of STC, all of Robotnik's computer systems and Badniks are wiped out by an electromagnetic pulse generated by Super Sonic. He never managed to regain his power base, despite the aid of the extra-dimensional Drakon Empire and he was eventually driven insane by his failures and imprisoned at last. The D.R.A.T. sprung up immediately after his defeat, campaigning to bring Robotnik back.

Adventures of Sonic the Hedgehog

In the Adventures of Sonic the Hedgehog, Robotnik has his own base of operations, a fortress located upon a hill with a large yellow or gold statue with hand salute. In the episode "Robotnikland", Dr. Robotnik takes over an amusement park called Mobiusland and renames this as Robotnikland, which he reprograms the rides to form a death trap. Sonic visits Robotnikland on his birthday as a trick by Scratch and Grounder.

In the Sonic Christmas Blast special, elements of the other contemporary cartoon appeared such as Princess Sally and versions of Robotropolis and the SWATbots.

Animated Series/Archie Comics


Robotnik's headquarters in Robotropolis from the Sonic the Hedgehog television series.

In the Archie-published Sonic comics and Sonic the Hedgehog television series, Dr. Robotnik had already conquered a majority of Mobius. His state and regime had no official name, though his seat of power was the captured royal city of Mobotropolis, which he renamed Robotropolis and converted into a factory city to produce his legions of robots.

Later in the Archie continuity, both the original Dr. Robotnik and Robotropolis were destroyed, though Robotnik was replaced by an alternate version of himself, who renamed himself "Dr. Eggman". Eggman established the Eggman Empire, which covers select regions of the Mobius and is currently engaged in open war with the Republic of Acorn. However, numerous setbacks have left the Empire in shambles. With the destruction of over 90% of his forces, as well as his capital city, Robotnik's last functional base of operations, the Eggdome, was remodeled into the Death Egg Mark 2.

Sonic the Hedgehog: The Movie

Movie Robotropolis

Robotropolis in Sonic the Hedgehog: The Movie.

In Sonic the Hedgehog: The Movie, Dr. Robotnik's empire is unnamed, though it includes the personal city of Robotropolis for Dr. Robotnik, and possibly the entirely of the Land of Darkness. Unlike the games, where Eggman wants to expand his empire, Robotnik seems content with ruling Robotropolis, and would rather simply destroy the Land of the Sky to make his empire the only ruling power in existence.

Sonic Underground

The Eggman Empire were also featured in Sonic Underground, where it is called the "Robotnik Empire". Much like in the Sonic the Hedgehog television series, the Robotnik Empire encompasses the majority of Mobius, with Robotnik's seat of power being the captured city of Mobotropolis, which he renamed Robotropolis. The city has a number of de-roboticized inhabitants, namely the nobility and inhabitants in the poorer parts of the city, though the former are largely ignored by Robotnik (since they are the source of his money) while the latter are under the constant threat of Roboticization.

Sonic X

In Sonic X, much like in the games, the Eggman Empire is Dr. Eggman own private empire that he seeks to establish worldwide, with him as the absolute ruling head of state. Throughout the series, the doctor's ultimate goal is expand the Eggman Empire across the globe. To this end, Dr. Eggman always seeks to take complete dominance the planet, but are constantly thwarted in his efforts by Sonic the Hedgehog and his friends.

When in Sonic's dimension, Dr. Eggman sought to spread the Eggman Empire on Sonic's world. After being transported to Earth, however, Dr. Eggman decided to try and re-establish the Eggman Empire there, but was stopped by Sonic, his friends and their new allies at every step. When Dr. Eggman and lackeys later on returned to Sonic's dimension, the doctor went back to his original plans of spreading the Eggman Empire on Sonic's world.

The decal the Docter uses varies, from black and yellow designs similar to those seen from Sonic Adventure 2, to more "evil" designs, such as a red and black variant that has much harder lines.


  • Even though Sonic Labyrinth was the first game to hint about an Eggmanland, the name and idea about Eggman's dream utopia has most likely took its basics from Sonic the Hedgehog OVA, that was released at Japan around that time.
