Long live the Eggman Empire!
The Eggman Empire is a technocratic dictatorship founded and ruled by scientific genius Dr. Ivo Robotnik (aka Dr. Eggman). At least, that is the doctor's dream. Throughout the Sonic the Hedgehog video game series, his empire consists of himself, his seemingly endless army of robots and whatever bases and installations he operates out of. While Eggman has managed to spread his influence worldwide, he has never been able to hold his ground. His schemes are constantly thwarted by Sonic the Hedgehog and his friends; however, Eggman refuses to give up no matter how many times Sonic defeats him, and while society has labeled him a lunatic and a terrorist, he will always see himself as a genius and a king.
Structure[]
The Eggman Empire is utterly techno-centric, favouring technological advancement and global-scale industrialization. Dr. Eggman's goal is the creation of a completely mechanized environment under his iron grip, holding no value or care for the natural ecosystem.
The social order of the Eggman Empire seems to favour those of scientific caliber; scientists that share Eggman's values (or lack thereof) are granted greater status, as are Eggman's own robotic creations. Of course, Eggman has always prefered the company of robots as they are less likely - or capable - of disagreeing with him, so the majority of the empire's citizens would likely be subjected to roboticization and installed within Badnik shells.
History[]
For a complete history of the Eggman Empire, see the articles Dr. Eggman, Dr. Eggman (Classic) and Dr. Eggman (IDW).
Territories[]
Scrap Brain Zone[]
Doctor Eggman's first known base of operations, appearing in the original Sonic the Hedgehog game. Located on South Island, Scrap Brain was a hellish industrial complex the size of a small city. Animals abducted from all over the island would be brought here and converted into Badniks that served Eggman's purposes. The complex was filled with all manner of traps and devices: crushing weights, conveyor belts, buzzsaws, electric pylons, flame vents and trap doors that opened up into bottomless pits.
When Dr. Eggman had his first showdown with Sonic the Hedgehog, he sealed off the centre of the factory and opened a disposal chute that sent Sonic plummeting into Scrap Brain's sewers. Sonic survived the traps and Badniks within and returned to the surface where he confronted the doctor in his Egg Crusher chamber. After Sonic destroyed his machine, Eggman escaped in his Egg Mobile and abandoned the base. Using the Chaos Emeralds he had acquired, Sonic erased all of Eggman's pollution scattered across South Island, presumably erasing Scrap Brain as well.
Gimmick Mountain Zone[]
Appearing in the 8-bit Sonic the Hedgehog 2 game, Gimmick Mountain was once an ordinary mountain until Dr. Eggman hollowed it out to construct a new Badnik factory inside. Within this hi-tech stronghold were many of the traps and gimmicks previously seen in Scrap Brain, such as flywheels, conveyor belts and crushing pistons. Sonic smashed his way through Gimmick Mountain and destroyed Eggman's Pig-Boar Mecha before moving on to the Scrambled Egg.
Scrambled Egg Zone[]
Adjacent to Gimmick Mountain was the Scrambled Egg, which may possibly have been an extension of the same base. Within the hollowed-out mountain were lines upon lines of light fixtures and twisting, winding tubes meant for transporting Badniks to different areas rapidly, indicating that the base may have been incomplete at the time it was destroyed.
The Scrambled Egg was guarded by the Silver Sonic, Dr. Eggman's first attempt at building a Sonic-based robot. Though it was powered by a Chaos Emerald, Silver Sonic proved to be no match for the real Sonic.
Crystal Egg Zone[]
The Crystal Egg was a bizarre location that completely diverted from Eggman's usual aesthetic standards. Instead of dull metal and menacing contraptions, this zone appeared to be made of sparkling crystal.
Here, Dr. Eggman attempted to trap Sonic within a deadly lightning chamber and recover the Chaos Emeralds from his corpse. Seemingly able to move faster than lightning itself, Sonic evaded the trap and defeated Eggman once more. Eggman fled from the Crystal Egg which was then shattered when Sonic unleashed the energy of the Chaos Emeralds.
Chemical Plant Zone[]
The Eggman Empire has established numerous Chemical Plants over the years, located in various parts of the globe. These areas are gloomy industrial cityscapes filled with facilities that constantly produce toxic chemicals that fuel Eggman's nefarious schemes. One such toxin produced by the Chemical Plants is "Mega Mack", a pinkish fluid that floods the entire complex.
The first Chemical Plant Zone was established on Westside Island during the events of Sonic the Hedgehog 2. After Sonic and Tails managed to end Eggman's operations there, the plant was left abandoned. The doctor would later re-establish the facility during the Phantom Ruby incident in Sonic Mania.
Another Chemical Plant facility was built by the Eggman Empire during the War to Take Back the Planet. This area was not solely used to produce weaponised chemicals, but also served as an Eggnet hub and featured a spaceport where shuttles would be launched to deliver supplies and prisoners to the Death Egg in orbit. This facility is believed to have been destroyed following the Resistance's victory.
Casino Night Zone[]
The Casino Night Zone is an urban centre on Westside Island dedicated solely to the entertainment industry. The entire city is essentially one big casino and amusement arcade, filled with various pinball machine devices such as flippers and bumpers. Giant slot machines can be found throughout the zone where visitors have the chance to either strike it rich or lose everything.
It is unknown if Dr. Eggman built the Casino Night Zone himself, but he was in control of it during the events of Sonic the Hedgehog 2. He used the profits from the casinos to fund the construction of the Death Egg and likely other contraptions as well.
Oil Ocean Zone[]
The Oil Ocean refinery is a massive industrial facility where the Eggman Empire pumps large quantities of oil. Eggman's blatant disregard for the environment is no more apparent than in Oil Ocean. True to its name, the facility sits in the midst of the sea, the waters around it having been heavily polluted by thick petroleum sludge. The rigs continuously churn out toxins into the atmosphere, making the area uninhabitable for any non-robotic lifeforms.
Metropolis[]
Metropolis was the capital city of Westside Island. What was once a vibrant urban sprawl became a polluted, hi-tech industrial hellscape when Dr. Eggman took over. Machines of incomprehensible purpose could be found everywhere, guarded by the most lethal Badniks Eggman could create.
Sonic and Tails were able to liberate Westside Island after storming Metropolis, attacking Dr. Eggman's citadel and sending him packing. While the Eggman Empire has attempted to reclaim Metropolis, it has never been able to hold its ground and the city remains a desolate, rust-covered ruin. Occasionally, scavengers enter the forgotten city to reclaim discarded Eggman tech.
Launch Base Zone[]
After the Death Egg first fell from orbit, it crash-landed on the flying continent of Angel Island. Doctor Eggman hastily constructed this Launch Base around the crash site in order to repair the Death Egg and get it back into space.
The base consisted of many large construction towers built over the flooded crater where the Death Egg sat. Badniks would toil night and day delivering materials and fashioning them into components to repair or replace the vessel's damaged systems. The base was defended by a number of lethal security devices such as laser gates, guillotines, spike traps and Snail Blaster robots. When the Death Egg was able to take off once more, the blast from its launch thrusters flattened most of the base, leaving only a few damaged structures standing.
Death Egg[]
A gargantuan armoured space station built in Dr. Eggman's mustachioed image. This satellite was to be Eggman's ultimate instrument of terror and domination, boasting enough firepower to annihilate whole landmasses. The Death Egg has been destroyed and rebuilt numerous times; its last appearance was during the events of Sonic Forces.
Little Planet[]
The Little Planet is a tiny planetary body that exists in an alternate dimension. Ordinarily a pristine landscape of lush greenery and sparkling waters, Dr. Eggman once attempted to use the Little Planet for his own villainous purposes, terraforming the entire planetoid and transforming it into an ugly, mechanical ecumenopolis. Eggman believed that the presence of the Time Stones would allow him to dominate the world and rule for all eternity, and so he chained Little Planet to the mountains surrounding Never Lake, anchoring it so that it would not return to its own dimension.
During the events of Sonic CD, Sonic the Hedgehog and Amy Rose ventured onto the mechanized Little Planet, only for Amy to be kidnapped by Metal Sonic. Rushing across the entire planet, Sonic sought out the Time Stones and destroyed Eggman's machines along the way. Travelling into the future, Sonic saw Little Planet in a ruined, neglected state, indicating that Eggman did not take proper care to maintain any of his machines. After confronting and defeating the doctor once more, Sonic rescued Amy and liberated Little Planet, returning it to its former splendour.
In Sonic the Hedgehog 4: Episode II, Eggman would return to Little Planet and build the shell of his new Death Egg Mk. II around the celestial dwarf. He would never get to test his new station's power before Sonic and Tails disabled the colossal construct.
Electric Egg[]
The Electric Egg was a hi-tech fortress located on South Island, protected by automatic laser cannons, bottomless pits, and spikes aplenty. This base served as a power plant and Chaos energy research facility of sorts. After obtaining one of the seven Chaos Emeralds, Eggman conducted experiments on it to figure out how to best harness its power. A side effect of the experiments was a series of tremors that caused South Island to sink into the ocean. However, Sonic and Tails recovered the Chaos Emerald from Eggman and destroyed the Electric Egg before the island was consumed by the sea.
Atomic Destroyer Zone[]
An underwater base where Dr. Eggman attempted to manufacture weapons of mass destruction utilizing Chaos energy. The base was defended not only by standard Badniks and Metal Sonic, but the doctor also piloted a variety of mechs in order to eliminate Sonic and Tails when they invaded the facility. In the end, these machines each failed and Eggman was forced to abandon the base, leaving behind the Chaos Emerald he had been using in his research.
Carnival Island[]
A mysterious, isolated island that arose from the middle of the ocean. After discovering the mystical Chaos Rings on the island, Dr. Eggman established a base there in the form of a high-tech amusement park. The park consisted of several themed zones, all littered with various Badniks and bizarre machines. The base was destroyed by Knuckles the Echidna and the Chaotix, after which the island sank beneath the waves once more.
Flicky Island[]
Flicky Island was a lonely, small island once inhabited by an ancient civilization. In the modern era, its only inhabitants are Flickies, a race of small birds that originate from another dimension. After detecting Chaos energy signatures coming from the island, Dr. Eggman established a base there and began turning the Flickies into Badniks to have them search for the Chaos Emeralds.
The Flicky Island base is comprised of two adjoining structures: Gene Gadget and Panic Puppet. Gene Gadget was a laboratory where Eggman conducted experiments on the Flicky birds he captured, while the Panic Puppet was a fortress built in Eggman's image. The Panic Puppet housed a Badnik production plant and also the Dimension Ring Generator, the device that Eggman used to access the Flickies' home dimension to lure more Flickies into his clutches.
After being alerted by Tails and Knuckles of Eggman's operation, Sonic travelled to Flicky Island to find it overrun with Badniks. Destroying every last Badnik he came across, Sonic freed the Flickies which, in turn, helped him acquire the Chaos Emeralds before Eggman could. When Sonic invaded the Panic Puppet, Eggman confronted him in a hi-tech battle-shell armed with numerous weapons. Sonic managed to destroy Eggman's final weapon, using the Chaos Emeralds to remove his influence from the island.
Final Egg[]
Eggman's base of operations during the events of Sonic Adventure. Located in the Mystic Ruins, it was a forbidding, high-tech stronghold that extended upward through a canopy of dense jungle. From here, Eggman researched the ruins of the ancient Echidna race and learned about the existence of Chaos, a watery monster that had destroyed the Echidna civilization thousands of years ago.
The Final Egg was filled with all manner of deadly gizmos: conveyor belts with spiked grinding devices at the end, laser barriers and self-destructing Beat robots that spewed out from the walls. The base was abandoned after Sonic defeated Eggman's Egg Viper mech.
Egg Pyramid[]
During the events of Sonic Adventure 2, Dr. Eggman operated out of a hidden base inside a pyramid located on the Sand Ocean. Though ancient, the pyramid was very sturdy and Eggman was able to renovate much of the interior without compromising the exterior. That being said, a number of smaller structures were dotted around the outside perimeter and many of the ancient stone carvings and murals have been replaced with Eggman's decal. A smaller pyramid stood next to the primary base which had been renovated into a launch site for spacecraft.
The full extent of Eggman's renovation is unknown, but the pyramid sported a number of mechanical implements. Pistons could be seen through the grated floors of the corridors and a massive power generator was located in the centre of the structure. The base was protected by various Badniks and key sections were sealed off by massive armoured bulkheads that required special keys to open. The base was also haunted by ghostly apparitions that would appear out of nowhere to attack or frighten intruders, though they would ignore the unfeeling robots that roamed the halls.
In order to reach the Space Colony ARK, Sonic and his friends raided Eggman's pyramid and stole a space shuttle. While trying to reach the shuttle, the group were attacked by the Egg Golem, a robot built to resemble an ancient statue. Sonic struck the restraining device on the Egg Golem's head, causing it to go haywire and attack Eggman. Eggman was forced to destroy the Egg Golem while Sonic escaped.
After the ARK incident, Eggman abandoned this pyramid base. It is believed to still be standing, with scraps of old Eggman tech still littering its chambers.
Rail Canyon[]
Rail Canyon is a region comprised of desert flats dominated by towering mountains and mesas. A network of rails runs throughout the region, all converging at Bullet Station, where the Eggman Empire had established a supply base. Eggman had begun constructing an army of Shadow Androids which were stored here until Metal Sonic took control of the Egg Fleet and planned to use them as his own army for global conquest. The base is believed to have been abandoned since then.
Cryptic Castle[]
A foreboding castle located in a dark, mysterious region. It is unknown what Eggman used this location for, though he was in control of the area prior to the events of Shadow the Hedgehog. Most likely the castle served as a private retreat for the doctor, though it turned out that the structure was haunted by evil spirits. When the Black Arms attacked, Eggman's forces were overrun and the castle was abandoned.
Iron Jungle[]
One of Eggman's military holdouts during the Black Arms conflict. This base was concealed by thick jungle and was manned by an army of Shadow Androids. The base was attacked by G.U.N., but their forces weren't able to withstand the Shadow Androids' assault. The real Shadow, however, fought through the army of doppelgangers and laid the base to ruin.
Lava Shelter[]
Lava Shelter was Eggman's primary base of operations during the Black Arms invasion. A reinforced bunker hidden inside a volcano, the base proved to be inaccessible for both the Black Arms and G.U.N., though not for Shadow the Hedgehog and the renegade Super-Badnik E-123 Omega. The pair were able to breach the defenses of Iron Jungle and enter the bunker where they destroyed all of Eggman's Shadow Androids.
Eggmanland[]
For many years, Dr. Eggman's greatest dream has been to construct his ideal city, Eggmanland, which will serve as the capital of the Eggman Empire. During the Chaos incident, he planned to destroy the city of Station Square and build Eggmanland upon its ruins, though this scheme never bore fruit. He would later try to use the Arks of the Cosmos to power its construction, but was unable to control their power and generated a black hole which he then left up to Sonic to fix.
During one of his most heinous schemes to date, Eggman lured Sonic into a trap aboard an orbital weapons platform, siphoning the energy of the Chaos Emeralds to power the weapon and using it to shatter the Earth into fragments. This resulted in the premature release of a primordial eldritch being known as Dark Gaia which dissolved upon awakening, its essence scattering across the shattered world. Eggman figured out a way to gather up the fragments of Dark Gaia and use its energy to fuel the construction of Eggmanland, which he built on top of one of the seven Temples of Gaia. Though Eggman had finally built his dream city, it would not be standing for long as Sonic reactivated the Gaia Temple beneath it, destabilizing its foundation and causing Eggmanland to plunge into the molten core of the planet.
During its short existence, Eggmanland stood as a glaring example of Eggman's twisted, narcissistic and childish nature. It appeared to be not so much a city, having no apparent housing for residents, but was more of a mish-mash of a titanic industrial complex and absurd amusement park. Factories and refineries made up the majority of the urban sprawl, the pollution they emitted perpetually darkening the sky above. Carnival rides such as waltzers and roller coasters were also scattered about the city, many of them connecting to the various industrial buildings as a demented form of mass transit. Throughout the city, Dr. Eggman's visage decorated virtually everything, a testament to the doctor's overwhelming vanity.
Egg Planet Park[]
A colossal theme park built in outer space, connected to a number of small planets. The park was linked to the Earth via a space elevator which guests were to take to reach the park. Supposedly, Eggman had built the theme park as a means of making amends for his previous crimes, but in reality the park was merely a cover for his next evil scheme.
Eggman had been capturing the inhabitants of one of the linked planets, the Wisps, in order to harvest their natural "Hyper-go-on" energy. With it, Eggman could power his latest weapon: a mind-control ray built into the core of the amusement park that would be projected at the Earth, brainwashing the entire population in one fell swoop. However, Sonic and Tails weren't convinced of Eggman's apparent reformation and had entered the park to investigate. Surely enough, they discovered Eggman imprisoning and abusing the Wisps, and upon freeing them, the Wisps helped Sonic by offering him their power.
After sabotaging the Hyper-go-on generators powering the mind-control ray, Sonic sent Tails back down to Earth while he confronted Eggman. Eggman fought Sonic in his Nega-Wisp Armour, but Sonic used the combined power of the Wisps he had saved to evade all of Eggman's attacks and destroy the doctor's mecha. Sonic then fled down the space elevator shaft before the amusement park exploded, releasing the planets that had been linked to it.
Lava Mountain[]
Lava Mountain is a volcano located on the skyborne planetoid of Lost Hex. During the events of Sonic Lost World, Dr. Eggman established a base of operations within the volcano. It was here that he built the Extractor, a device designed to drain the life energy of the planet below.
Eggman's plan was to siphon small amounts of the world's life energy, enough to weaken the planet and its inhabitants so that they could not resist when his Badnik armies invaded. However, the Deadly Six, a group of monstrous Zeti that Eggman had enslaved, broke free of the doctor's control after Sonic kicked away the Cacophonic Conch that Eggman was using to control the Six. The Zeti then turned on Eggman, using their innate ability to control magnetic fields to hijack Eggman's Badniks and take over his operation. Taking over the Lava Mountain base, the Deadly Six turned the Extractor to full power, intent on making themselves stronger by sucking the planet below dry.
Dr. Eggman was forced to team up with Sonic and Tails to stop the Deadly Six, though he was actually merely using them to get close enough to the Extractor to regain control of it. After faking his own death and infiltrating Lava Mountain, Eggman accomplished his goal while Sonic fought and defeated the Six. He then used the Extractor's remaining life energy to power a giant robot with which to kill Sonic, but the heroic hedgehog defeated the machine and Eggman was sent falling back to Earth.
Arsenal Pyramid[]
During Sonic Forces, the Eggman Empire conquered 99% of the planet. One of the conquered regions was Green Hill, where Eggman constructed the Arsenal Pyramid: a pyramid-shaped structure containing a hi-tech weapons factory that supplied munitions for Eggman's ongoing war effort. Though Green Hill was known for being a lush natural paradise, much of the area had been turned to desert as a result of Eggman's industries.
After Sonic rejoined the Resistance following his escape from the Death Egg, he led a Resistance raid on the Arsenal Pyramid, breaching the factory's defences and shutting the facility down, liberating the slaves that were being worked to death on the assembly lines.
Eggman Empire Fortress[]
The Eggman Empire Fortress is located in a barren gray wasteland that has similar-looking mountains surrounding it. In the center of this region lies the fortress itself. This high-tech fortification is 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, and the paths around the fortress consist of bridges through metallic canyons that are fortified with lasers, missile launchers, and robots. Rising up from the center of the crater is the Imperial Tower, a massive high-tech tower with tall metallic pieces forming hoops circling around it. The fortress also has several floating platforms. In the innermost part of the fortress, below the Central Tower, lies the main reactor for the Phantom Ruby, powered by three Phantom Ruby prototypes. This reactor is hidden behind a defense system too tough to be broken through by normal means.
This is where the final battle of the Phantom Ruby War takes place. After neutralizing Infinite's Phantom Ruby prototype, the Resistance pushed ahead, sending its fleet to engage Eggman's aerial forces while Sonic and the ground troops charged through the fortified canyons. After defeating Infinite and shutting down the base's reactor, Sonic and his allies fought Eggman's Mega Death Egg Robot. After Eggman was beaten once again, the fortress was left abandoned.
Egg Base Alpha[]
One of several facilities established by Dr. Eggman during the War which had yet to be dismantled by the Restoration following the conflict. Since Eggman recovered from his "Mr. Tinker" stint, the base continued to operate. It would later be taken over by Dr. Starline, Eggman's protégé during the Metal Virus incident. It is unknown if Eggman took the base back following Starline's demise.
Egg Base Delta[]
A large industrial complex with many large smoke towers, cranes, metallic buildings, and what appear to be floating platforms. The base is constantly surrounded by a haze of green smog.
Egg Base Sigma[]
A modest industrial facility by Eggman Empire standards. This base was taken over by Dr. Starline when the platypus launched his own campaign for world domination. With the aid of several escaped criminals, Starline infiltrated the base, hacked into its computer systems and proceeded to erase it from the Eggnet before co-opting its Badnik forces. From here, Starline programmed and trained his cyborg minions Surge the Tenrec and Kitsunami the Fennec in preparation for his ultimate plan to co-opt Eggman's whole empire. After Starline's death, the base was left abandoned and Eggman has yet to reclaim it.
Eggperial City[]
Doctor Eggman's latest high-tech cityscape and headquarters. Possibly the doctor's most ambitious terraforming project to date, the machinery located beneath this urban sprawl would siphon minerals from underground which would fuel the city's growth, allowing it to expand continuously until it had completely engulfed the surface of the planet. The energy needed to sustain the city was provided by a series of enormous artificially-created crystalline spires that replicated the properties of the Chaos Emeralds.
Eggperial City suffered two attacks during its brief existence. First, Dr. Starline temporarily seized control of the city during his Operation: Remaster scheme, but lost the city - and his life - after falling in battle against Dr. Eggman. Some time after Starline's demise, Sonic and the Restoration would organize an assault on the city, receiving assistance from Team Dark during the operation. Shadow the Hedgehog was able to use the artificial Chaos Emerald spires to overclock his Chaos Control power, teleporting Eggperial City into space.
Members[]
The following is a list of noteworthy individuals who currently serve - or have once served - the Eggman Empire.
Doctor Eggman[]
Doctor Ivo Robotnik, better known to the world as Doctor Eggman, is a human scientist who specializes in robotics and mechanical engineering. Boasting an IQ of 300, the doctor considers himself to be the greatest genius the world has ever known and is determined to make the people of the world acknowledge his brilliance. Self-entitled and arrogant, Eggman believes that the world and its inhabitants will be better off under his rule and has sought to conquer the planet and establish the Eggman Empire.
To fulfill his desires of world domination, Eggman has created countless robots and machines to carry out his plans. Believing in the superiority of technology over nature, the doctor's plans have frequently involved extensive industrialization, causing significant harm to the natural environment. Eggman has shown little to no concern for the ecosystems he has ruined over the years, believing that his hi-tech sprawls and industrial complexes are better than anything that nature can provide. He has also enslaved the animal inhabitants of these lands to use as living batteries for his Badnik robots.
An egotistical narcissist of the highest caliber, Dr. Eggman is extremely vain to the point that he builds most of his machines in his own likeness. Rarely subtle, he has a flair for the theatrical and wants his enemies to know when he is at large. He is always so confident in his abilities and schemes that he tends to overlook any potential flaws in his plans. This behaviour has made Eggman somewhat predictable as his plans continue to be foiled regularly by his arch-nemesis, Sonic the Hedgehog. Regardless of how many times Sonic and his friends have bested him, Dr. Eggman refuses to give up no matter what. Unwavering tenacity and a stubborn refusal to compromise or accept defeat are traits that Eggman and Sonic share, so in that regard at least, Eggman begrudgingly holds some degree of respect for his long-time adversary.
Orbot[]
Orbot is a diminutive assistant robot created by Dr. Eggman. Usually accompanied by fellow robo-lackey Cubot, Orbot's job is to keep Dr. Eggman informed of the progress of his schemes as well as perform menial tasks such as preparing the doctor's meals or operate certain machines.
Orbot has a calm and soft-spoken demeanour most of the time. He can be very passive-aggressive and often talks back to Dr. Eggman and points out flaws in the doctor's schemes. Despite Orbot's insolence, Dr. Eggman still keeps him around, perhaps out of loneliness more than anything else as the doctor spends very little time with people.
Cubot[]
The dim-witted Cubot is one of Dr. Eggman's robot lackeys, along with his counterpart Orbot. While Orbot frequently gives Eggman back-talk, Cubot is somewhat more loyal, though much less competent. He often makes dim-witted comments and is prone to making mistakes. Eggman likely only keeps Cubot around for the same reasons as Orbot: to have someone to talk to and to berate for whenever his plans go awry.
Sage[]
One of Dr. Eggman's more recent creations, Sage is an advanced artificial intelligence program. Eggman originally developed Sage both to protect him and assist him with his research on the technology left behind by the Ancients. As Sage carried out her duties, Eggman not only took pride in her abilities but would even come to genuinely care for her as though she were his daughter. Sage, too, would come to view the doctor as her father.
Sage almost faced her destruction during the events of Sonic Frontiers, though she ultimately survived and returned home with her father. Since then, Eggman has likely granted Sage total access to the Eggnet, granting her control of every robot and facility in the Eggman Empire.
Metal Sonic[]
Metal Sonic is, as his name implies, a robot doppelganger of Sonic the Hedgehog. While he is not the first Sonic robot Eggman has made, he is arguably the most lethal and certainly the most enduring.
Metal was designed for the sole purpose of destroying Sonic; Eggman not only built Metal's body to surpass all of Sonic's abilities, but he was programmed with all of Sonic's life data, making him capable of understanding Sonic's thought process and how to counter the hedgehog's attacks. Over time, Metal has been modified with the ability to analyse the bio-data of other opponents so that he can mimic their abilities.
Metal is capable of a greater degree of autonomy than other Badniks. This has led to him betraying Eggman more than once and striking out on his own to defeat Sonic, though he has never succeeded with or without the doctor's help. He has been rebuilt many times; with each resurrection, he has become more and more obsessed with fulfilling the purpose he was built for, even to the extent that he believes that he is the "real" Sonic.
Infinite[]
Formerly the leader of a band of mercenaries, the jackal that would become known as "Infinite" joined forces with Dr. Eggman after a failed raid on one of the doctor's laboratories. Exposed to a mystical gemstone called the Phantom Ruby, he saw a vision of his greatest desire: a world wiped clean of life. Realising that he had merely been going through the motions and despised the current state of the world, the "ultimate mercenary" decided to help the doctor in his quest to establish the Eggman Empire.
Infinite would become Eggman's greatest weapon as he waged war across the planet. Having had a duplicate of the Phantom Ruby fused to his body, the nihilistic jackal could freely use its power to create virtual-reality constructs, warping the environment around him and spawning endless copies of Eggman's minions to overwhelm his enemies. He even managed to defeat Sonic in battle and capture him, but eventually Sonic's allies would free him.
In the final push of the War to Take Back the Planet, Sonic and an unknown member of the Resistance fought against Infinite and managed to defeat him. Infinite disappeared in a flash, seemingly retreating to Eggman's tower, but made no appearance during the Resistance's final battle against Eggman himself. Infinite's status and whereabouts since the war are unknown.
Doctor Starline[]
A platypus scientist who is skilled in several fields, including robotics, cybernetics and computer hacking. Long a great admirer of Dr. Eggman, he was responsible for the madman's return to villainy following a brief stint as the kindly "Mr. Tinker" following his defeat in the War. Having restored the doctor's mind and providing him with the Chaos Emeralds, Starline was welcomed into Eggman's employ as his protégé.
However, Starline became disillusioned as he witnessed Eggman's mismanagement of the Metal Virus pandemic. Going behind Eggman's back, he recruited the Deadly Six, whose natural electromagnetic powers could allow the doctors to regain control of the Zombot hordes. Having previously been used and abused by Eggman in the past, Zavok and his pack were quick to take over Eggman's Faceship and attempt to dominate the planet themselves using the Metal Virus. After being forced to ally with Sonic and the Restoration to stop the Deadly Six, Eggman fired Starline and banished him.
Infuriated at being cast aside, Starline decided that he would conquer the world his own way and show Eggman how to be a better villain. While he nearly succeeded in stealing the Eggman Empire out from under his idol during Operation: Remaster, Eggman fought back and soundly defeated his one-time protégé.
