Dr. Ivo "Eggman" Robotnik


 * Robo-Robotnik redirects here. For the first version of Robo-Robotnik seen in Sonic the Hedgehog #19, see Robo-Robotnik (alternate version). You may also be looking for the article on Dr. Ivo Robotnik (from Sonic the Hedgehog issues 1 — 50). For other versions, see Robotnik (disambiguation).

Doctor Ivo "Eggman" Robotnik (aka Dr. Ivo Robotnik, Robo-Robotnik v2.0, Robotnik Mach II or the Eggman) is a version of Dr. Ivo Robotnik from another zone. In his native universe he was defeated by the Freedom Fighters after he roboticized himself, only to survive by uploading his digital consciousness to an unfinished space station he had constructed. He was first encountered by a denizen of Mobius Prime when Dr. Ivo Robotnik was inadvertently teleported to future version|that universe by his renegade creation E.V.E.. From this encounter Robo-Robotnik learned about the Giant Borg and eventually managed to rebuild a new body for himself with pieces he acquired from it. From there he proceeded to bombard the surface of his Mobius with atomic weapons, killing his nemesis King Sonic and the entire Royal Family. With no one left to fight, and having discovered that the Robotnik of Mobius Prime had been killed, he travelled to Mobius Prime to "fill the void" in both his life and Sonic's, assuming the role of the despotic dictator after his death. He came to be known as Dr. Eggman after his original robotic body was destroyed, and after a period of time switching through robotic bodies he was de-roboticized by the Bem, becoming flesh and bone once more. Dr. Eggman, and acting as the primary antagonist in the Mobius Prime reality. After suffering numerous setbacks to his conquest of Mobius Prime, Dr. Eggman's mental stability declined, nearing the point of insanity, until he finally succumbed to complete madness following a major defeat by Sonic, and was subsequently locked away by Snively, only to escape and be captured by the Freedom Fighters and imprisoned once again. During the Iron Dominion's takeover, he started to reflect on his past life and identity, and regained a semblance of his sanity and finally escaped from New Mobotropolis's prison after the fall of the Iron Queen. He returned to the Eggdome with Snively and the local Dark Egg Legion chapter to plan for his renewed battle with Sonic.

Origins and Initial Defeat

 * See also: Dr. Ivo Robotnik - Early Life to Betrayal and Rise to Power

Robo-Robotnik's early history was largely the same as his Mobius Prime counterpart's, including his jealousy at Colin for receiving more attention from their parents, the things he did in the Great War, his coup d'état to take over the Kingdom of Acorn and his war aganist the people of Mobius. There are some minor differences however, such as Robo-Robotnik roboticizing his universe's version of Colin Kintobor earlier on. (StH: #92, #197, #200, #206, #209)

The main difference in Robo-Robotnik v2.0 and Robotnik Prime's history occurred in the year 3232 when he roboticized himself in order to defeat the Freedom Fighters. This effort proved unsuccessful, and his body was destroyed in the seemingly final confrontation. In reality, Robo-Robotnik managed to transport his digital consciousness to an incomplete and derelict space station he had created for other purposes. Despite his survival, Robo-Robotnik remained stranded on this space station, awaiting inevitable shutdown. (StH: #22, #75, #108)

A Second Chance and Victory
Years later, Robotnik Prime was inadvertently transported by his renegade creation E.V.E. to Robo-Robotnik's future reality onto the space station Robo-Robotnik's consciousness was stranded on. Once there, Robo-Robotnik appeared on a monitor and explained that the space station was still incomplete, keeping him mired in space until its systems ran down, which would ultimately end his existence. In response, Robotnik Prime convinced him that even if they failed in this zone, by sending him back to his own zone, they both still stood a chance. Following this, he returned Robotnik Prime to Mobius Prime. (StH: #22)



The meeting inspired Robo-Robotnik to fight on, and when he transported Robotnik Prime home, he tapped into his memories and learned about the Giant Borg (which was controlled by an alternative version of himself) and that pieces of it had been distributed throughout the various zones of the multiverse. Locating the piece hidden in his own future reality, Robo-Robotnik proceeded to create a new artificial body for himself with the piece. He then bombarded Mobotropolis with nuclear weapons, wiping out King Sonic, Queen Sally, Princess Sonia, Prince Manik, and the Freedom Fighters, securing his total victory in that zone. (StH: #75)

With all of his enemies killed in his native zone, Robo-Robotnik found himself with nothing to do. After discovering the death of his Mobius Prime counterpart, he decided to take advantage of the death of his "other self" by moving to Mobius Prime and wiping out his enemies there, "filling the void" in both his life and Sonic's. (StH: #75)

Conspiring from the Shadows
Robo-Robotnik proceeded to conspire from the shadows for several months onboard a group of satellites he brought with him from his own zone. He used each satellite to cause a series of events on the planet surface, first to open the jail cells in the Devil's Gulag prison to release Snively, the Fearsome Foursome, Drago Wolf and Sleuth "Doggy" Dawg, then to cause an avalanche in the Southern Tundra, which nearly buried Sonic and Tails. Following this he activated a series of traps and robots by the Lost Temple of Shazamazon, restored Kodos and Uma Arachnis to their organic selves, hurled a series of meteorites at Mobotropolis, activated a giant Mutate which attacked and captured Snively, fired a time beam at Knothole which could have destroyed all time, and presented a autobiography on the life of Dr. Robotnik over King Max's speech. (StH: #62, #64, #67, #68, #70, #71, #72)

Shortly afterward, Robo-Robotnik recruited Evil Sonic to go to the other various realities and have the local versions of Sonic hand over their pieces of the Giant Borg in order to reassemble the machine. Evil Sonic succeeded in doing this, but while in the Sonic Underground universe, the last one to give up its piece of the Giant Borg, Evil Sonic confused the local Robotnik for Robo-Robotnik, and gave him control of the Giant Borg. Because of this, Robo-Robotnik deciding he should "cut my losses and forgo the battle-suit", returning to his secret satellites in Mobius Prime for his upcoming scheme to re-take Mobotropolis. (SSS: #10)



After returning to Mobius Prime, Robo-Robotnik used his satellites to remove the Robians' free will, making them subservient to him. He then had them abandon Knothole and begin working on board his space station. When the Freedom Fighters realized the Robians were absent, they discovered the satellites in space with help from NICOLE. Realizing they were likely responsible for the numerous problems which had occurred over the past few weeks, the Knothole Freedom Fighters went to investigate the space stations. Once they arrived on board Robo-Robotnik, wearing a skin disguise to fool everyone into thinking he was Robotnik Prime back from the dead, revealed himself and his use of the Robians as his slave labor force. (StH: #73, #74)

After his skin disguise was removed by acid, Robo-Robotnik captured the heroes in a force field, and explained he deliberately lured Sonic and the Freedom Fighters to his space station, as it allowed his Shadowbots to re-capture Mobotropolis. Freed from the force field by Snively, the Freedom Fighters enlisted his help to blow up the orbital platform with Robo-Robotnik on board. Although Robo-Robotnik managed to deport the Robians to the recaptured and rechristened city of Robotropolis, he was prevented from leaving the space station himself when Sonic attacked him. Sonic's attacks proved futile against his robotic body, but soon Sonic's parents revealed they managed to maintain their free will, and were quickly taken by Sonic to the last escape ship. Stranded on board the space station, Robo-Robotnik's body was destroyed along with the station when it exploded. (StH: #74, #75)

Birth of Doctor Eggman & Early Schemes
Despite his robotic body being destroyed in the explosion along with the space stations, Robo-Robotnik simply transported his consciousness into a new robotic body, which was hidden half a mile below Robotropolis. With his new body, he took on the new name: Dr. Eggman. With the city of Robotropolis recaptured, Eggman attempted to download the location of Knothole and launch an immediate attack. However, Sally, NICOLE and Snively successfully planted a virus in the city's computer systems, preventing him from downloading its location. (StH: #75, #76, #77)

After clearing the entire memory bank of all infected data, Eggman discovered a digital file the late Robotnik Prime had regarding the mysterious water beast Chaos. Eggman decided to use Chaos to destroy his enemies. After breaking the Black Emerald and releasing a weak Chaos, Dr. Eggman and a contingent of Shadowbots flew to Angel Island and attacked the Chaos Chamber, shattering the Master Emerald and using its pieces to make Chaos stronger, while also causing the island to fall into the ocean. (StH: #78, #79)

Although Eggman managed to aid in allowing the water creature to evolve into Perfect Chaos, the creature decided it no longer would listen to the dictator's orders, and thus destroyed his Egg Carrier sending Eggman falling into the flooded city below. After Perfect Chaos' defeat by Super Sonic, Knuckles and Tikal, Dr. Eggman demanded revenge, and dispatched Silver Sonic II to Station Square to kill Sonic. After a brief battle however, Silver Sonic II was defeated and reprogrammed by Nate Morgan to act as the city's defender. Thus, when Eggman returned, he was chased out of the city by his own robotic creation. (StH: #83, #84, #85)

Before Eggman returned to Robotropolis, the Royal Army and Knothole Freedom Fighters launched an attack on the city, freeing the captured Elias Acorn and obtaining the means to bring Queen Alicia back to health. During this time, Dr. Eggman found himself chased out of Station Square, only to stumble upon the lab and diary of his great-grandfather Professor Gerald. Using his great-grandfather's notes, Dr. Eggman sought about reviving Project Shadow for his own uses. (StH: #88, #89, #98)

Having learned of the Sword of Acorns' ability to restore the Robian's free will, having witnessed it occur on the video files of the Mobian's attack on his city, Dr. Eggman focused his efforts on obtaining the sword. Although he managed to do this, it was stolen from him by Uma Arachnis and given to Kodos. (StH: #89, #90)

Weeks later, Eggman discovered a large group of Overlanders, including the Mobius Prime version of his brother Colin Kintobor and his family, had returned to Mobius from a trek through outer space. Having missed his people for so long, and wanting to roboticize this version of his brother, as he had done in his own universe before coming to Mobius Prime, Dr. Eggman created a ruse in order to win the Overlanders trust and lure them into Robotropolis. (StH: #92, #93)

Roboticizing with a Touch
Still existing in a robotic body, Dr. Eggman enlisted the help of his nephew Snively to enable his body to roboticize beings with a single touch. The two set to work, and after weeks of experimenting the process was successfully tested on the Overlander Cheddermund. With this new ability, Eggman hoped to roboticize Sonic and the others by luring them into the city using Nate Morgan as bait. Although the Freedom Fighters went to Robotropolis and managed to restore the free will of the Robians there using the Sword of Acorns, which was given to Sally by Uma Arachnis, they managed to escape the city when Nate turned off the city's dome shield. Having remained behind, Dr. Eggman roboticized Nate, turning him into a robotic statue as he had done to Cheddermund. (StH: #94, #95, #100)

When Hope pointed out she felt Dr. Eggman was responsible for the Robians, he proceeded to inform the Overlanders they were all suffering from radiation poisoning, and needed to be roboticized or they would die. When Colin learned that Dr. Eggman was a robot and had convinced Snively to help him, Dr. Eggman roboticized Colin as well as Lady Agnes, hoping to also roboticize Hope Kintobor with them. Hope was rescued before she could be captured however by Sonic the Hedgehog. Soon afterward, Eggman demonstrated to the Overlanders they could retain their mobility as long as they wanted to be roboticized, by roboticizing a willing Snively. However, the Overlanders decided to leave the city with the Freedom Fighters, as the Mobians pointed out Dr. Eggman waited for them to get radiation poisoning until it was too late. The Overlanders were allowed to leave, as Eggman felt watching their suffering would be more enjoyable. (StH: #105)

Due to the reality warping of Chaos Knuckles, Dr. Eggman was able to create a device to bring back the original Dr. Ivo Robotnik. The two mad scientists then schemed to lure the Knothole Freedom Fighters into Robotropolis and use the same device to disperse their molecules. However, having learned from Dr. Quack that without the device the original Dr. Robotnik could not exist, the Freedom Fighters went along simply to gain access to the device and destroy it. Following this, the original Dr. Robotnik's molecules dispersed forever. (StH: #108)

Body Hopping & De-Roboticized
As a robot, Dr. Eggman maintained his ability to transport his consciousness into new robotic shells. Following the destruction of Robotropolis due to a nuclear strike from Station Square, Dr. Eggman began constructing a new robotic body for himself in the ruins of Old Megaopolis, though this was detected by Station Square's spy agent Rouge the Bat. When Rouge went missing, the President hired Sonic and Bunnie Rabbot to investigate. Bunnie freed Rouge while Sonic destroyed Eggman's new robotic body with a piece of dynamite. (StH: #110, #116)

While stranded in cyberspace, Eggman attracted his system's self-defences, allowing Snively's consciousness to be transported into a new robotic body. After Snively made a new look for himself, Eggman destroyed the body and emerged in his new robotic form, telling Snively he was the main villain. In this form, Dr. Eggman traveled to the Forbidden Zone where the Fearsome Foursome, Sleuth "Doggy" Dawg and Drago Wolf offered to sell him back one of his old factories. Dr. Eggman agreed in order to shake Drago's hand and roboticize him, as well as roboticizing the Fearsome Foursome. Before he could roboticize Sleuth however, Sleuth informed him he would give him Sonic the Hedgehog, who traveled to the Forbidden Zone to rescue his childhood friend Tommy Turtle. Sonic managed to grab Tommy from Sleuth and nearly escape, causing Eggman to switch his attention to Sleuth and roboticize him. Just before he did however, Sleuth threw a grenade which destroyed Eggman and Snively's robotic bodies, and caused Sonic to think Tommy had died in the explosion. (StH: #117)

Shortly after this encounter, Eggman found himself captured along with Snively, Sonic and Tails by an alien race known as the Bem. Eggman and Snively were transformed back into flesh and blood, and forced to battle for their lives against a roboticized Sonic and Tails in order to prove whether or not flesh is superior to metal. After losing to Mecha Sonic and Mecha Tails, both Eggman and Snively were sent back to Mobius in their organic forms. Additionally, they are unable to re-roboticize themselves due to a side-effect of the Bem's de-roboticizer. (StH: #118)

The Xorda Crisis & Re-Conquering Mobius
Not long after this, Mobius was attacked by another alien race called the Xorda. The Xorda had attacked Mobius over twelve thousand years ago when the planet was still known as "Earth", and had thought all intelligent life had been wiped out. When the Xorda encountered ships carrying Overlanders, the descendants of humans, they returned to Mobius to find the planet still inhabited. When the Xorda attack Eggman's forces, he realized the Xorda posed a legitimate threat, and asked for an alliance with the Kingdom of Knothole, but at the price of surrendering half of the his aquirred territory to the Kingdom. With the help of Sonic and Sally, the Xorda ship was forced to retreat. Unwilling to leave the job unfinished, the Xorda left behind a device called the Quantum Dial intended to destroy the world and the entire solar system. Sonic successfully prevented the device from going off, but was teleported to another side of the universe in the process, leaving everyone to believe he died. (StH: #124, #125)

Now unopposed by Sonic the Hedgehog, Eggman seized the opportunity to re-conquer sections of Mobius which were lost after the original Dr. Ivo Robotnik's death, thereby creating the Eggman Empire. Establishing a new capital city for his empire in New Megaopolis outside the ruins of Old Megaopolis and Megaopolis, Dr. Eggman also went about creating two robotic "children" to replace the still-missing Snively, who disappeared during the Xorda's attack, called Mecha and A.D.A.M.,the formor as his bodyguard and the latter being a sentient computer virus which controlled most of the Eggman Empire's systems and robotic armies. (StH: #130)

Dr. Eggman also took this time to strike a deal with the Dingo Regime, providing weapons and other support for them in return for their allegiance and becoming his enforcers on Angel Island. With the Dingoes now an ally and under the new leadership of Kage Von Stryker, he successfully conquered the Angel Island and maintained control of it for months, enslaving most of the Echidna population. During a bid to captured the Master Emerald, the Brotherhood of Guardians managed to defeat Eggman's Egg Pawns, but were captured in their weakened state by Dr. Finitevus, leaving the echidnas and Master Emerald under the sole protection of Locke until the Dark Legion chose to aid him. Eggman would also ally with the Iron Dominion like his alternate self did. (StH: #138, #139, #183, #194, #200, #207)

In addition to taking over the echidna settlement on Angel Island, Dr. Eggman sent in his forces to invade the hidden city of Albion, having its location provided to him by Dr. Finitevus who also sabotaged the city's defenses. With the city defenseless, Eggman's forces destroyed the city,and its citizens sent to the Egg Grapes where they perished. In another attempt to control Downunda, Eggman established the first Dark Egg Legion chapter with former Freedom Fighter Duck Bill Platypus as its Grandmaster. He would go on to establish other chapters, including one in the southern continent under Drago Wolf and Razorklaw, though the name Dark Egg Legion would not apply until the Echidna chapter joined the Eggman Empire. (StH: #182, #214, SU: #11)

When Sonic returned months later, Dr. Eggman decided to initiate Operation: Triple Threat; a nuclear strike against Station Square and Knothole, while also sending a horde of upgraded SWATbots to take down the force field containing the nuclear radiation around the nuked Robotropolis. The horde was intercepted at Fort Acorn by the Mes Braves Battalion, the Chaotix and an expeditionary force from G.U.N. while the Knothole Freedom Fighters attacked Dr. Eggman and his battleship armed with the nukes. Eggman managed to escape from Shadow the Hedgehog, who arrived as well to stop the mad doctor's schemes, but the nukes were delayed from launching when Tails occupied A.D.A.M.'s thought process, giving Bunnie Rabbot the time she needed to destroy the battle ship. He would later learn that several former Robians had been "Re-Roboticized", apparently by a being calling himself Anonymous. At the same time, an Auto Automaton operation of his involving Tommy Turtle was under way, but foiled by the efforts of the Freedom Fighters. (StH: #130, #131, #132, #133, #135, #136, #137)



Shortly after this failure, Dr. Eggman sent in his forces to invade Golden Hive Colony, capturing or killing most of its citizens and turning it into one of the Eggman Empire's polluting bases. It was also around this time that Locke had been captured while holding off Dingo forces while the Dark Legion relocate the Master Emerald to the Hidden Palace Zone. Learning of his father's capture, Knuckles the Echidna went to Angel Island with Sonic and the Chaotix and successfully rescued Locke with the help of the Dark Legion. However, Dr. Eggman, not wanting to rely on the Dingoes, sent his new agent Hunter to capture some of the free echidnas as well as retrieve the Master Emerald. Hunter successfully sent numerous echidnas to the Egg Grape Chambers including Remington, but was soon defeated when Knuckles transformed into Super Knuckles and sent Hunter flying off the island to his death. Rather than think of it as a loss, Eggman told his 'daughter' Mecha that given the amount of people captured by Hunter and sent to the Egg Grapes, it was a partial victory. (StH: #138, #139, #140, #141)

Eggman later introduced a new army of robots to the top threats to his empire, including Sonic, Tails, Knuckles, and Amy. Later, after discovering Freedom Fighter activity near an abandoned bunker, Eggman would create a new Metal Sonic to investigate. His robot would engage Sonic, Shadow, and a prehistoric robot named Isaac in battle, though the robot would form a truce with his fellow automaton and learn about Mobius' history from him before being destroyed. Later, frustrated with his efforts to conquer Mobius, Eggman unwittingly gave A.D.A.M. clearance to utilize nanites in their efforts, having developed the technology in creating his new Metal Sonic. (StH: #145, #146, #147, #148, #149, #152)

Some time later, after developing a vehement hatred for Mina Mongoose's music, which led him to ban it in his territories, he hired Nack the Weasel to assassinate her. After that failed, he dispatched new versions of Heavy and Bomb to eliminate her, only for that to meet with failure as well. His next scheme involved sending an army of Robian Dragons to the city of Vesuvio after learning its location from Dulcy the Dragon, who then helped destroy his forces. Anonymous would then send him a warning that he was to be terminated, and Eggman decided to go to Sonic for help; they were then forced to deal with the threat of a reprogrammed Mecha and Knothole's hijacked Metal Sonic Troopers. At the same time, he was able to convince Shadow to join him as an agent of the empire in exchange for knowledge about his past. He was then surprised to learn that A.D.A.M. had contact with nanites seized by the Freedom Fighters, allowing them to infect NICOLE, Jules Hedgehog, and Bunnie Rabbot. (StH: #153, #154, #155, #156, #157, #158, #159)

Continuing his vendetta against Sonic, Eggman dispatched three agents against Freedom HQ on Sonic's birthday: Bark the Polar Bear, Bean the Dynamite, and Croctobot, all of whom were subsequently defeated. Then, as he prepared to use the Egg Grapes in his efforts to mine the Zone of Silence for energy, the Egg Grape Chamber was invaded by the Arachne, who utilized the Sword of Acorns and forced him to evacuate. Upon returning, he found the Grapes gone and his old foe Ixis Naugus escaped. The wizard then departed in search of the Crown of Acorns, and Eggman then destroyed Mecha after receiving footage from A.D.A.M. that showed her working with Anonymous. After terminating all his other "henchmen" projects, leaving only A.D.A.M., he deployed the Egg Fleet to capture not only Naugus' force but also Mammoth Mogul and the Destructix, who had joined forces to battle the Freedom Fighters and Chaotix. (StH: #160, #161, #162, #163, #164)

After capturing Jet the Hawk, leader of the Babylon Rogues, Eggman decided to hire him and his associates to attack Knothole and humiliate Sonic, though their use of Extreme Gear was countered by Tails' creations. The doctor had also by this point established-or else would later establish-loose ties with the Battle Bird Armada, an organization that the Babylon Rogues had deserted for their own purposes. Eggman also convinced Snively to rejoin the empire as commander of the Egg Fleet. The doctor subsequently set up an Auto Automaton Infiltrators operation in Casinopolis under Renfield T. Rodent, but was thwarted by the Chaotix. (StH: #163, #164, #166)

Not long after that, he revealed to A.D.A.M. that he had discovered that A.D.A.M. was in fact Anonymous, having witnessed his release of Mammoth Mogul and Ixis Naugus from the Egg Grapes and learned of his involvement in Anonymous' plots. He proceeded to delete A.D.A.M., only for his "son" to return by taking over the nanites infused into Tommy Turtle's shell. Eggman was then taken to the nanite city, where A.D.A.M. faked his communication signal to bring in Shadow, who had been dispatched after Mogul and Naugus. Eggman then watched as Jules, under the control of A.D.A.M.'s nanites, brought him Tails as Eggman was remotely summoning the Egg Fleet, which A.D.A.M. revealed he had detected. A.D.A.M. then activated a large machine in the center of the city to begin using Tails and Shadow's respective powers to draw in the Chaos Emeralds from across Mobius and other planets across the galaxy. After Sonic arrived and began engaging A.D.A.M., eventually leading to a battle between their Super transformations, Eggman freed both Super Shadow and Turbo Tails, who sent the Emeralds to another zone. Tommy was then able to override A.D.A.M.'s control of the nanites fused to his body long enough to open himself to fire from the Egg Fleet, whom Eggman had terminate his foe before departing. (StH: #168, #169)

Shadow himself soon betrayed Eggman, stealing Gerald Robotnik's diary and deserting the Empire to pursue his own destiny. Eggman was then able to capture Sonic and use a special device to control his actions and have him attack Knothole, but was defeated in both this attack and dispatching yet another Metal Sonic model by the combined efforts of Sonic's friends. Following this setback, Eggman sent Nack, Bark, and Bean to investigate a supposed auction of the Master Emerald, but all three were captured. He also suffered defeat in attacking the old Power Ring Grotto and the Chao who had taken up residence there, as Sonic, Knuckles, and Tails intervened. However, his plans continued to move forward, and he even caught Espio the Chameleon as the Chaotix member invaded his headquarters, gaining a measure of revenge for Espio's role in destroying his captured Golden Hive Colony holdings.(StH: #171, #173, #174, FCBD 07)

Eggman's then launched a large-scale offensive against the Kingdom of Knothole, using his massive Egg Fleet to inflict heavy damage via aerial bombardment, effectively destroying the entire Kingdom and Freedom HQ. During this attack, he managed to capture the entire population (bar Sonic, Tails, Knuckles and Amy), transporting them to his Egg Grape Chambers to be used as a source of fuel for his city. He also engaged in a one-on-one duel versus Sonic wearing his newly created power armor called the Egg Beater, thrashing Sonic physically and psychologically before he departed. Eggman came to regret his decision when the four survivors launched a rescue mission that foiled his plans and liberated the prisoners. The Mobians were subsequently transported to New Mobotropolis when NICOLE altered the programming of the Egg Beater to transport them there, as opposed to the Egg Grape Chambers. In retaliation, he redeployed his Egg Fleet (lead by Snively) to attack the city's shield while he fought Sonic in his Egg Beater. The combined might of Sonic, the Freedom Fighters and the Chaotix proved too much for his power armor, resulting in its destruction and causing Eggman to flee, slowly losing his grip on reality as well. (StH: #175, #176, #177)

Turning of the Tides
When Dr. Eggman learned of the return of Enerjak, he accepted Sonic's proposed temporary alliance so that the two could defeat the chaos demigod. Arriving at New Mobotropolis during Enerjak's attack there, he successfully had the Egg Fleet transport him to the last Egg Grape Chamber. Keeping his end of the bargain, Eggman withdrew from New Mobotropolis with the captured Enerjak, saying he wanted the place kept tidy for when he decided to return and destroy it. However, Eggman underestimated Enerjak's power, and was shocked when the demigod escaped captivity and destroyed not only his Egg Fleet but the vast majority of New Megaopolis. Following this, Eggman withdrew to his bunker with Snively and the recently arrived Dimitri to plan. (StH: #180, #181, #182, #183)

Following the defeat of Enerjak, Eggman accepted an alliance proposed by Lien-Da for the remaining Echidnas loyal to her to become the new Dark Egg Legion in exchange for robotic enhancements. Eggman agreed knowing that he'd already given the title of Grandmaster to Dimitri, despite Lien-Da only allying under the terms that she would be the Grandmaster. (StH: #184)

Sometime later, Eggman sent Metal Sonic to attack Freedom HQ, only to discover that it was under the control of Scourge the Hedgehog and the Suppression Squad. Metal Sonic was just about to leave when Eggman heard Scourge say he was planning to take control of the areas that the Eggman Empire had conquered, causing him to have Metal Sonic attack Scourge. When Sonic arrived, Eggman realized that Metal Sonic was outnumbered and built a duplicate of Scourge, Metal Scourge, to help. While the doctor was watching the battle from the Eggdome in New Megaopolis, Dimitri came to him and demanded to know why he had not yet built a new Badnik army to help the Dark Egg Legion. Eggman revealed that he had planted bombs in the cybernetics of the Legion's members, causing Dimitri to realize just what he had gotten himself into and leave. Eggman presumably continued to watch the fight between the two hedgehogs and his robot duplicates until the latter were both destroyed. (StH: #191, #192)



However, this did not discourage the good doctor, who proceeded to construct yet another Metal Sonic. This newer version was equipped with a special engine which would allow it to travel to other dimensions. Upon activation Eggman told it to locate Sonic, who at the time had been trapped on Moebius. When Metal Sonic teleported itself there without orders, Eggmans began to yell and throw his tools around in a fit of rage. (StH: #195)

Eggman later created a new weapon called the Egg Phoenix and used it to counterattack the Freedom Fighters'/Chaotix's assualt on the Eggdome. The Egg Phoenix proved to be a match for the two groups, but Sally came up with the plan of having Sonic, Vector, Knuckles, Tails and Bunnie use teamwork to lead the Egg Phoenix straight up into the air to make it stall out. With the fires out on the Egg Phoenix, Saffron, Charmy and Ray planted Neutralizing Mines on the craft's hull allowing Tails to deactivate the Egg Phoenix and caused it to crash. Eggman escaped unscathed and ordered Snively and Dimitri to round up the Dark Egg Legion for the final battle. (StH: #197, #198)

The day after, Eggman dispatched the last of the E-100 Series, E-123 Omega to hunt down and destroy the rogue E-102 Gamma, much to Omega's displeasure as his original programming was to destroy Sonic the Hedgehog and not this lower task. The Freedom Fighters and The Chaotix then launched an assault on the Eggdome in an attempt to defeat Eggman once and for all, while the Dark Egg Legion held them back. Secretly following Snively's plan, the legion later retreated to let Sonic get through and even saluted him when he was about to confront Eggman. Sonic then went down the chute where Eggman was waiting in his Egg Tarantula. (StH: #199, SU: #3)

Descent into Madness and Imprisonment
Confronting his rival about how he had conquered the planet, Eggman's sanity was pushed to the breaking point as Sonic taunted and recounted the numerous times he'd defeated the dictator, and a long and grueling battle ensured in which he showed increasing signs of instability. Sonic soon gained the upper hand and struck Eggman down by destroying the Egg Tarantula as the evil doctor was ejected from the machine. Right after Sonic proclaimed his victory yet again it caused the doctor to lose his mind entirely, going as far as to rip his own moustache. Screaming and drooling he made a swing at Sonic, missing and falling to the floor. As Sally walked in on the scene, she found Eggman lying on the ground, now having descended into madness and babbling incoherently. At this point, Snively walked in, remarking how Sonic had not just defeated his uncle, he had broken him. Instead of rejoicing at the defeat of their oppressor, Sonic and Sally merely looked with pity and horror at what had become of the once-mighty Eggman. After the Freedom Fighters left New Megaopolis to celebrate, Snively placed Eggman in a padded cell and handed over control of the Eggman Empire to the Iron Queen and her dominion. (StH: #200)

Not too long afterward, Snively and the Iron Queen attacked New Mobotropolis by having the latter use her powers of Magitek on Bunnie D'Coolette and later Monkey Khan, but when Bunnie was taken away from her and Khan was restored to his senses the two fled. Snively went back to the Eggdome and took a look in on Eggman, who was busy mumbling nonsense sentences, some regarding his previous actions, mathematical calculations, hating Sonic, feeling less loved than his brother Colin, his former lackey Crabmeat and food. Once Snively left him thinking that gloating in his uncle's face a waste of time, Eggman muttered the words "Cell block override epsilon-gamma-gamma" and the door sealing him in the padded cell unlocked. (StH: #203, #204)



Snively heard the sound of the door unlocking and thought that Eggman had broken something, only to see his uncle escape his straitjacket and confront him for "Snooping as usual". Eggman then tossed Snively aside and rushed off to one of his machines to escape the Eggdome with only one intention: destroying Sonic. Blowing a hole in the dome, he scared away the Yagyu and DEL, ranting as he went into the Great Forest with his Egg-Tortoise, searching for Knothole by tearing up the forest tree by tree. He encountered his target there and after recognizing him attempted to destroy him with the missiles from his mech but Sonic kept avoiding them. His lack of notice for Tails was the walker's downfall as Tails managed to shut the whole robot down from a control panel in its underbelly. Sonic then attempted to reason with Eggman but he just punched the hedgehog. He soon fainted after a fit of laughter at 'getting' the hedgehog. As Sonic and Tails were discussing what to do with the Doctor, the Iron Dominion arrived on the scene and demanded that the heroes relinquish him to their custody and surrender themselves. Sonic proceeded to engage them while Tails dragged the unconscious Eggman back to New Mobotropolis where he was greeted by Sally and Monkey Khan, the latter wanting to kill Eggman for his atrocities, but Sally convinced him that he was more valuable alive and had him incarcerated in the New Mobotropolis Prison. After forcing the Iron Dominion to retreat (with the help of the Freedom Fighters and NICOLE), Sonic visited Eggman in prison, the delusional former dictator being so out of touch with reality as to think that he had just made his defection during the Great War decided to rest up for his audience with the king. (StH: #205, #206)

Later, during the Iron Dominion's invasion, Eggman was visited by his nephew while scribbling numbers and figures on the walls, his moustache growing back. Confronting his uncle about how pathetic he had become, Snively Robotnik marched up to Eggman and announced that he would be lording over a greater empire than his had ever been. The speech however was useless on the mad doctor who merely asked Snively when he had lost all his hair, completely killing the mood. (StH: #208)

Recovery & Escape
When his old "friend" Sir Charles was escorted to the detention center, Eggman, in his delusion, asked how his invention the "Robot-sizer" was coming along, only to get a cold rebuke from the aged hedgehog. In a moment of clarity, Eggman reflected on the use of his adopted name, remembering that he used to go by "Julian" but that it had been a long time since he had done so. Studying his glasses he began mumbling: "I go by Robotnik now, and sometimes... "Eggman" ...of my Eggman Empire..." With that, he put his glasses back on, seemingly regaining some semblance of his lost sanity and began thinking over why he could never defeat Sonic. (StH: #209)

Eventually, he found the answer, leading him to make a near full recovery, and stated to a visiting Snively that the reason he could never defeat Sonic was due to the hedgehog's over exposure to Chaos Energy, making him the embodiment of chaos, an unforseen variable in any experiment. He then asked him to be released from his cell. However, Snively refused, stating he has everything he has wanted, including love. After learning Snively's "love" was Regina Ferrum, Eggman laughed in his face and declared him a deluded fool, who could never find love since the only person he ever cared for was himself, and the woman he supposedly loved was merely a stepping stone to him in his goal for conquest who would play him as easily as Snively himself would her. This reduced his nephew to tears and he stalked off, Eggman all the while laughing at him, saying he'd be back to serve him once again. Sure enough, the Iron Dominion was toppled by the efforts of the Freedom Fighters and Regina was captured, leaving a terrified Snively to free his uncle, both of them escaping New Mobotropolis in the confusion. (StH: #210, #211)

Hiding & Scheming
One week afterward, Eggman had a recovering Lien-Da and the Dark Egg Legion back under his command in the lower levels of the Eggdome, secretly watching Sonic's returns to the site around the Eggdome, searching for the Doctor. Eggman saved Sonic from the Krudzu Hybrid Hydra with a humming bird like robot when it threatened to eliminate Mobius's hero, stating that no one, not even himself was allowed to destroy the hedgehog, much to Snively's annoyance. He continued to gleefully watch Sonic and Tails's failed attempts at finding him and finding safety in numerous surveillance system re-routings, he dismissed Snively's worries of being caught. When Snively suggested that they journey to the Dragon Kingdom to rescue the Iron Queen from jail, the doctor swiftly put his nephew in place and told him flatly, "We're not wasting any of MY time or resources busting YOUR girlfriend out of jail!" Submissively, the tiny Overlander complied as his overbearing uncle petted him like a lapdog. Eggman then set about building more machines. (StH: #212, FCS: #4)

Later on, Eggman had Snively brought to him under watch by armed legionnaires, revealing that he was aware of Snively sending supplies off to the Dragon Kingdom to legionize the Raiju Clan. Defending himself the tiny overlander claimed to have done so to make them the regional enforcers, in response the despot demanded his nephew to officially end his relationship with his former Sub-Boss, Regina Ferrum, immediately. Brought nearly to tears, Snively reluctantly complied, making a vow under his breath in the process. (StH: #218)

During this whole time, Eggman also supervised Lien-Da's recovery while installing more cybernetics and upgrades into her and making her look almost completely natural using his craftsmanship. After installing a replacement explosive, he showed her what he had done and explained it as all being part of a game he played with Snively and his Grandmasters to see how far the "trust" of each other would benefit them, to which Lien-Da accepted gladly. (StH: #220)

Eggman and his loyal minions worked on his latest project for quite some time, while telling his nephew to pick up the pace and meet him at the Zone Gate he was informed by Lien-Da that all systems were up and running, and that the hull damage had been repaired. Afterwards, Eggman took Snively with him to the Special Zone through the newly constructed Zone Portal, faced with a literal god the two overlanders were subjugated to one of Feist's games to prove themselves worthy of the prize. Racing against each other through a tube Eggman shot Snively's craft down and claimed victory, Feist gave him the choice between bringing Snively, or the emerald back. Unsurprisingly, Eggman chose the gem and promptly returned to the Eggdome where he activated a teleportation device to bring Snively back as well, much to the panda's otherworldly fury. (StH: #223)

Reemergence
After weeks of labor Eggman made the finishing touches to his new project, putting the battery in place the doctor roundabouts with his lieutenants on the command deck where he was pleased to find that all systems were online and the engines ready for take off. After initiating the countdown Eggman gleefully watched on as his masterpiece charged up the launch preparations, reducing the surrounding ruins to a further state of decay the Death Egg blasted off into the clouds and headed straight for New Mobotropolis. (StH: #224)

Abilities
Eggman's most well known ability is his masterminded plots and schemes which only fail due to Sonic and his friends and Eggman's own arrogance. He is a remarkable scientist and engineer, as evidenced by the armies of robots and mechs he's created. Some of them within mere hours. He is an incredibly skilled pilot: able to manipulate many different kinds of his own mechs and robots in difficult battles with Sonic. Eggman used to have the ability to roboticize someone with a single touch, as well as transfer his consciousness between robotic bodies, enabling him to survive "death".

Personality
Eggman has shown himself to be far more prone to toying with his opponents than his Mobius Prime counterpart on numerous occasions. As opposed to simply wiping out Knothole from the get-go, Eggman decided to "have fun" with his Mobian enemies and take the time and resources to engage in "war-games". Eventually he grew tired of this, and decided to use the Mobians as a source of fuel for his capital city via the Egg Grape Chambers. When his mechanical "daughter" Mecha asked if there wasn't a far more efficient and easier method to powering his city, Eggman responded with a nonchalant "Where would the fun in that be?"

Like Robotnik, Eggman is also arrogant, and egotistical, both of which may be his greatest weaknesses. He has a habit of frequently putting "Egg" into the names of numerous inventions and places (Egg Fleet, Egg Pawn, Egg Lobster, and Egg Grape Chamber to name a few). When Hunter was capturing Echidnas en masse, a crudely designed Eggman face was seen above each capture and a similar face is used as the logo of the Eggman Empire. As a matter of fact, the Egg Pawns needed only a mustache to have Eggman's face. Meanwhile, Eggman has the annoying habit of thinking that his plans are foolproof, even when the flaws are quite obvious, (Metal Scourge done on the fly, Egg Grapes needing retooling for Enerjak, telling Dimitri about the explosives, etc.) and not realizing that there may be a problem until it's too late, and at one point of desperation, he even ordered his Egg Fleet to fire on his enemies while he was standing right next to them without concern for his own well being. As Snively has openly admitted, "The big guy is losing his marbles". Following the destruction of his entire city, the loss of 99% of his forces, the betrayal and subsequent deaths of his "children" and his never ending litany of defeats at the hands of Sonic and the Freedom Fighters, Eggman began to fall apart mentally, frequently ranting utter nonsense to everyone and no one in particular, not bothering to think things through, and suffering sporadic memory loss (such as when he refered to Snively as "Colin" and the Dark Egg Legion as the "Dark Alliance"). In one instance, he was perfectly willing to use a super-weapon that would destroy not only the Freedom Fighters, but also half of the Eggdome and everyone in it at the time, simply to finally get rid of Sonic, which Shadow and Rouge both noted as proof that Eggman is losing all grip on reality (though Sonic remained skeptical).

As of his defeat by Sonic in their "final battle" the evil doctor has gone completely insane from his repeated losses and hatred of Sonic, now unable to differentiate between events that occurred ten minutes ago from those that occurred ten years ago; for example, he uses the Egg Tortoise to search for Knothole long after he himself destroyed it. However when Uncle Chuck is being escorted into the detention center, he calls the doctor by his name and Eggman examines his glasses in his hand. He muses that he used to go by "Julian" but considers that it's been years since then, adding that he now uses "Robotnik" or "Eggman," slowly putting on the glasses and remembering that he is Eggman of "his" Eggman Empire.

By the time the Iron Dominion solidified their hold on New Mobotropolis, Eggman had, as Snively put it, "reasoned [himself] back from the brink." He had even theorized the reason he could not defeat Sonic but Snively still kept him locked away until the dominion's defeat was imminent. After returning to the Eggdome, Eggman had seemingly regained most of his sanity, though displaying slightly more prominent mood swings than before.

Background Information

 * Dr. Eggman's current look was introduced to coincide with the version of Robotnik in the Sonic Adventure videogame. Although primarily known as Eggman in the comics, he is sometimes still referred to as Robotnik to prevent newer readers from getting confused.
 * Eggman had other robotic bodies hidden underneath Robotropolis, but it is unknown why he didn't use them. All of them have similar features and similarly coloured uniforms. One of them even appeared to be fashioned after the famous wrestler Hulk Hogan. Since Dr. Eggman was meant to resemble his current look in the games, the out of continuity explanation is quite obvious. The explanation in continuity was only hinted in the letters pages and a Q&A held on Ian Flynn's forum, with Eggman thinking his new form looks good. (2) Interestingly enough, Robotnik Prime's first reaction to Eggman's appearance was to call him a "boob".
 * Many people have noted that Eggman's descent into insanity is similar to that of his Fleetway, Sonic the Comic counterpart.
 * When Dr. Eggman loses his sanity, he uses what the original Dr. Robotnik said each time he was defeated by Sonic, "I HATE THAT HEDGEHOG!". The line "I HATE THAT HEDGEHOG!" was used by the Dr. Robotniks of the Adventures of Sonic the Hedgehog and Sonic "SatAM" series.
 * Eggman's line of "Snoo-ping as usual" in StH #205 is a nod to the internet meme Robotnik Pingas, well known among Sonic fans on YouTube. (3). His line "I'm going to be on TV! I'm going to be a TV Star!" is from the same series and gained meme status from a video made by the same user who made the term "Pingas" popular.
 * Eggman makes reference to his theme song from Sonic Adventure 2 called E.G.G.M.A.N. during his escape from the Eggdome, saying, "I will destroy the blue one, you know! He's the obstacle that always gets in my way!"
 * Although they are usually covered by his moustache, Eggman does have ears.

One or Two Robo-Robotniks?

 * Some argue that the version of Robo-Robotnik seen in StH #22 is the same Robo-Robotnik in StH #19 Former writer Ken Penders who wrote both stories confirmed on his website the two were the same person.(1) Additionally StH #75 firmly established that the two were the same Robo-Robotnik, which was solidified by Dr. Eggman's Data File from StH #108. Despite this, current writen Ian Flynn decided to retcon this and made the Robo-Robotnik from StH #22 separate from the one in StH #19. This is a result of the fact that the two seem to have minor differences in their histories and both Robotnik's failed to recognize one another in StH #22. Despite in-comic canon considering the two the same Robo-Robotnik, Ian Flynn's position, soon to be reflected in the upcoming Sonic the Hedgehog Who's Who Volume 1, is accepted as the official canon on this site. Ian Flynn's position on the debate was officially printed in the Sonic Free Comic Book Day 2011, where information on Dr. Eggman was presented in the back of the issue.

Appearance
Originally Eggman was near identical to Robotnik Prime save the black/blue appearance due to being roboticized. After the loss of his first robotic body, he settled for a more streamlined design. Tall even for an Overlander, Eggman remained obese but became somewhat burlier and less flabby with long, almost disproportionately thin arms and legs. His head is now round as opposed to pointy adorned with both tinted glasses and goggles, and his moustache greatly grew in length, density and mass. Gone are the cape and overlord outfit, in it's place an elegant, red coat sporting two square metal buttons on both sides of the chest in gold with white stripes and yellow cuffs on the sleeves with white gloves covering his hands, and a pair of black pants with matching boots seemingly attached to them bearing circular plates on the both sides of the ankles and three square ones riding up the shin. It was later revealed that behind his pince-nez glasses were the same black eyes with red irises of his original flesh and blood form.
