Doctor "Eggman" (IDW)

Past
For years, Dr. Eggman has been attempting to achieve world domination, only to be thwarted by Sonic the Hedgehog and his allies at every turn. Some of Eggman's plots have included trying to take ownership of the Chaos Emeralds (multiple times no less), and attempting a plot involving the Death Egg. Each time however, Sonic stopped him.

While Eggman created many machines over time, his finest creation was none other than Metal Sonic. One time, Eggman personally repaired him after the robot took a beating from Sonic.

Perhaps the earliest known conflict between Sonic and Eggman included a battle between the two where Eggman piloted his Egg Viper mech. However, Sonic winded up defeating him. Another encounter involved the Space Colony ARK, in which Eggman used its Eclipse Cannon to blow up a part of the moon in order to show the world the power that he wielded. These events lead to Eggman teaming up with Sonic, Tails, Knuckles, Rouge, and Shadow to stop a bigger threat endangering the world.

Later, Eggman was betrayed by Metal Sonic, who had somehow transformed into a new form known as Neo Metal Sonic. Neo Metal Sonic disguised himself as the doctor and tried to take over the Eggman Empire, clashing with Team Sonic along the way. In the end though, the heroes prevailed and defeated the robotic menace, causing him to revert back into its normal form. Eggman would then repair Metal Sonic and remove his rebelliousness from its coding. At a later point in time, Eggman came into the possession of Gemerl and programmed him to be violent. However, Gemerl was eventually defeated by Sonic and his allies.

When the Black Arms later invaded, Eggman fought this alien menace with his forces alongside other factions, thus giving the heroes of the world the time needed to stop the Black Arms. Eggman would later shatter the planet with the Chaos Energy Cannon, but had his plot undone by Sonic. Eggman soon after attempted a takeover of Planet Wisp, but Sonic put a stop to his plans, thus saving the Wisps inhabiting the planet. Following this, Eggman discovered the Time Eater and used its powers to mess with time. During this incident, the doctor fought Sonic with the Egg Dragoon, but lost. Eventually, Eggman tried using the Time Eater against Sonic, only for the hedgehog to defeat him. Not beaten yet, Eggman attempted a plot on the Lost Hex that he called "The Lost World Project". There, he used an ancient relic to take control of the planet's local inhabitants, the Deadly Six. Sonic had later unwillingly freed the Zeti from Eggman's control. The Deadly Six thus turned on Eggman and used their electromagnetic powers to take control of his Badniks. Regardless, Sonic had managed to stop them and Eggman.

At some point in the past, Eggman hired a group of mercenaries. However, they did not last long against Sonic and Shadow. Later on, Eggman struck a deal with a mercenary named Mimic to destroy the latter's own team, the Diamond Cutters, who had been previously taking down several of his bases. After Mimic lured them to another one of Eggman's bases, the doctor locked them in a room and unleashed his Shadow Androids on them to kill them. Following this, Eggman forgave Mimic for his "crimes" against him. Eggman soon discovered that one of the members, Whisper the Wolf, was not killed and ordered Mimic to finish the job. Mimic later brought Whisper's Wispon and mask before him as evidence that he killed her. Eggman accepted this and let Mimic go.

The Eggman War and aftermath
Eventually, Dr. Eggman managed to defeat Sonic and lock him up, thus allowing his Eggman Empire to conquer the majority of Sonic's world. However, after six months of conquest, Eggman's empire began to fall apart after Sonic's friends freed Sonic. As a part of his preparations for what he thought would be the final battle, Eggman began the process of upgrading Metal Sonic to Neo Metal Sonic in order to use him as his greatest weapon in said final battle. In addition, the doctor uploaded his own bio-data into Neo Metal Sonic, giving the robot his genius, drive and vision. He also removed the limitations that kept Neo Metal Sonic from achieving his final form. Before Eggman could complete Neo Metal Sonic however, Sonic and the Resistance broke the Eggman Empire's control over the world. During this decisive battle, Eggman fought Sonic in the Death Egg Robot. After being defeated, Eggman disappeared.

Having somehow survived his defeat, an amnesiac Eggman turned up in Windmill Village. The villagers quickly locked Eggman up, only for Eggman (now displaying a friendlier disposition) to break out and reinforce his cell. The villagers proceeded to test Eggman for days, and never once did he show signs of his villanous ways, leading them to the conclusion that he suffered from amnesia. Eventually, the villagers nursed his wounds and took him in. Returning the villagers' kindness, Eggman would repair anything the villagers brought him, both big and small. In time, Eggman became beloved by the village, who began calling him "Mr. Tinker".

Approximately a month after disappearing, Eggman would, after observing a child cry over a broken wagon from the shadows, promise that he would soon fix it and "everything" else.

The Fate of Dr. Eggman
Eggman was eventually discovered by the Chaotix, who wanted to bring Eggman to justice. Having a hard time believing the story about Eggman's amnesia, the team interrogated and observed Eggman for a couple of days, only to conclude that his amnesia was legit. However, this presented the Chaotix with a new dilemma: whether or not it was right to penalize Eggman now that he was a good man with no recollection of his evil deeds.

Eggman was soon after introduced to Sonic, whom the Chaotix had brought in, by Charmy. Seemingly not remembering Sonic, Eggman attempted to greet him. However, Eggman got scoffed by a suspicious Sonic, who began questioning him. When Eggman proved unable to answer Sonic's questions, Vector had him return to his work while he and the others discussed what to do about Eggman. When Badniks then approached the town, Eggman took in upon himself to ensure the safety of the village's children, much to the surprise of Sonic, whom Eggman begged to help them. After the Badniks had been dealt with, Sonic and the Chaotix decided to leave Eggman to his new life in the village. Eggman's thus had a proper greeting with Sonic when he and the Chaotix prepared to leave. However, after Eggman expressed his hope that the hedgehog would come back to visit so that he could show him "Eggman Land" once it was completed, the group noticed Shadow and Rouge on the rooftops, with the former seeking to eliminate Eggman after hearing him mention "Eggman Land". When Shadow tried to get to the nervous Eggman however, Sonic intervened and lured Shadow away. Eggman subsequently withdrew to his house with Rouge watching over him until Shadow returned. The hedgehog abrasively demanded that he showed him "Eggman Land", to which Eggman complied: he took the heroes to a cabin that held a kids play area that he had been constructing in secret. Eggman explained that name "Eggman Land" came to him while constructing it, and believed it to be a ridiculous-sounding name that the kids would find funny. After Shadow and Rouge departed, Eggman and Sonic shared some parting words, with Sonic promising Eggman that he would be back soon.

Battle For Angel Island
While singing for the children playing in his Eggman Land amusement park, Eggman received a visit from Rough and Tumble. The skunk brothers proceeded to kidnap Eggman, who cried out for help as he was being taken away. He was subsequently brought to the Final Egg and was restrained. There, Eggman met Dr. Starline, who was interested in bringing back Eggman to his former glory. Despite Eggman's protests against being anyone else but the one he was now, Starline ignored him and started to electrocute him through the use of special goggles. After finishing the first round of his procedure, Starline asked Eggman if he was feeling more like himself.

After three sessions using neuro-stimilants and aggressive hypnotherapy, Eggman began gravitating towards his old inventions, but not his old personality. After Eggman built a shrub-trimming Moto Bug, Orbot and Cubot tried helping him remember by suggesting that he should abuse them amongst other things. However, Eggman dismissed this notion and instead showed them kindness. When a badly damaged Metal Sonic then arrived in the Final Egg, Eggman initially took pity on him. However, the sight of Metal Sonic made Eggman remember his past with him, prompting his memories and old personality to resurface. Having no recollection of his time as "Mr. Tinker", Eggman demanded an explanation on everything. While Dr. Starline introduced himself and brought Eggman up to speed, Eggman went to work repairing Metal Sonic while ordering Orbot and Cubot to fetch his old clothes. Eggman was then introduced to Starline's associates, Rough and Tumble, who did not impress Eggman until he heard that they hated Sonic. As such, he offered to make them weapons and sent them after Sonic, something the skunk brothers gladly accepted. As he got dressed, Eggman heard how Starline helped get him back to old self. During Starline's story, Eggman was also introduced to Starline's Warp Topaz. Although the gem did not impress him, Starline instead provided Eggman with the seven Chaos Emeralds as his "apprenticeship application". Impressed, Eggman accepted Starline as his newest lackey.

After reviewing the attempts Neo Metal Sonic made to return the Eggman Empire to global dominance in his absence with Starline, Eggman decided to go with a new plan instead of trying with Neo Metal Sonic again. However, he needed time to test and prepare, so he assigned Starline to distract Sonic in the meantime. When Rough and Tumble then complained to the doctor about their weapon designs, the doctor simply swapped the blueprints between the brothers as they had each received the incorrect one. Afterward, Eggman began reviewing the schematics on the Metal Virus. Although, Cubot was unsure if he wanted to unleash it on the world, Eggman was firm in his decision, having decided to make the world suffer for his latest indignity.

Infection
Taking Dr. Starline's advice to mess with Sonic, Eggman had him sent Sonic a message instead of making a global proclamation that foreshadowed his return and would bait him into Rough and Tumble's hands. When Eggman later finished his first batch of the Metal Virus, Starline confirmed the execution of his bait for Sonic. Although Starline thought an ambush would be sufficient, Eggman assured him that this was subtle for him. After that, he and Starline began experimenting with the Metal Virus. Using a flower and some animals as test subjects, Eggman saw with glee how his virus transmuted flora and fauna into robotic slaves through touch while leaving processed and inorganic matter alone, making him declare his Metal Virus a success. Noticing Starline's pride in their collaboration, Eggman questioned him about how he found him, to which Starline explained that he used his Warp Topaz. With it, Starline showed Eggman the battle Sonic and Tails had with Rough and Tumble. When the skunk brothers stood to loose though, Eggman turned his attention towards implementing the Metal Virus for the next phase of his plan in spite of Starline's reservations about having so few data samples on it. When Rough and Tumble then asked for a second chance, Eggman saw Metal Sonic step up to take a shot at Sonic. While Eggman found it delightful, Starline offered to let him take a shot at Sonic.

After sending Starline, Eggman returned to his studies of the Metal Virus. After an experiment, he discovered that the virus's infection of a victim accelerated with each new exposure to infected victims. With this discovery, Eggman begun planning to administrate the Metal Virus in different places for the next phase of his plan. However, he got interrupted by Rough and Tumble, who were tired of waiting and wanted him to make good on his promise to help them beat Sonic. Noticing an opportunity, Eggman told them that his "latest weapon just got out of beta". Later, after seeing Starline's attempt to kill Sonic with a bomb, Eggman angrily pulled Starline through his Warp Topaz's portal when he tried to return to base and told him that Sonic was his to kill and that simply destroying him is unsatisfying to him. After Starline apologized, Eggman let him go and checked the video feed from the bomb site. As Eggman had suspected, Sonic survived the explosion. Eggman then asked Starline why he saved his "obsolete junk" at the bomb site, to which Starline explained that they were collectibles of Eggman's legacy to him. Allowing this, Eggman asked Starline of his impression of Sonic, to which Starline said that the experience had "put a lot of things into a new perspective."

Later, Dr. Eggman, Orbot and Cubot were preparing special backpacks containing the Metal Virus when Starline informed Eggman that Sonic and Amy had hacked into the Eggnet in Echo Mine. Taking this well, Eggman told Cubot to get Rough and Tumble to meet him in hangar three. As Eggman walked off with his backpacks, Starline worried about the situation, but Eggman told him to get used to them. In the hangar, Eggman showed Rough and Tumble the backpacks and told them to open them in case Sonic gained the upper hand. However, Eggman did not reveal what would happen to them. He then presented the skunk brothers with a large tank with a drill and cannons to use against Sonic. Rough and Tumble soon after attacked Sonic and Amy in their tank, which Eggman and Starline observed through surveillance. However, the skunks quickly lost their tank and then got themselves unwillingly covered in the Metal Virus in their backpacks, turning them into Zombots. Although Rough and Tumble got trapped in a refuse pit, Eggman was pleased with the outcome, as they had managed to infect Sonic with the Metal Virus. He then explained to Starline that it was time to share the Metal Virus with the rest of the world.

Heading into the new Faceship, Eggman told an amazed Starline about how he put it together so quickly and the limits of his Badniks, which he would replace with Zombots. Onboard the Faceship, Eggman had Orbot and Cubot launch it and take them towards their first target. Eggman then gave Starline a tour of the Faceship, showing him things like the power generator (which were the seven Chaos Emeralds), the viewing area, and the Metal Virus factory. In the meantime, Eggman gloated about the global army of Zombots he would soon command, which would allow him to carry out any project and conquer other worlds and dimensions. While Starline supported Eggman's vision, he noted that he could not cover the whole planet in his Metal Virus. In response, Eggman told Starline that by dropping the Metal Virus in a few populated habitats, the Zombots created would spread the virus quickly. Eventually arriving over Windmill Village, Eggman had the village dowsed in the Metal Virus. With the population quickly turned into Zombots, Eggman asked Starline for his opinion, who told Eggman that he had exceeded his expectations. Eggman accepted the compliment and immediately sent the Zombots out to invade other villages.

Tangle & Whisper
Dr. Eggman soon discovered that Mimic had not only lied about killing Whisper the Wolf but she was the one who helped turn the tide of battle during the Eggman War. Eggman swiftly got back into contact with Mimic and ordered him to actually kill Whisper this time or he would hunt him down. Much later, Eggman was told by Mimic that he managed to kill both Whisper and Tangle the Lemur, but the doctor wanted physical evidence of that. When Mimic drove back to the site of where he blew up Eggman's former base to kill the girls, Eggman told him that he did not need more people opposing him and stated that he would send Metal Sonic after him if he did not succeed. Mimic did not manage to find the bodies of Tangle or Whisper but was led by footprints to a small ditch that had the words "WE END THIS WHERE WE STARTED" engraved into it. From this, Mimic asked Eggman for backup.

Crisis City
Eggman next took the Faceship to Seaside City and distributed the Metal Virus there, transforming many of its citizens into Zombots. Eggman later formulated a plan to distribute the Metal Virus in Floral Forest Village with the Faceship, which was where Cream the Rabbit lived, meaning Sonic would head into a Zombot outbreak to attempt to rescue Cream while risking his own safety. After Sonic arrived, Eggman mocked the hedgehog over the telecoms. Eggman later told his newly transformed Zombots to pile up on Sonic. However, Cubot reported back that the Zombots were ignoring his command. Orbot also showed him that there had been a steady decline in Zombots responding to Eggman's commands since the beginning of Eggman's plan. This made Eggman hypothesize that there had to be a random mutation in the Metal Virus coding due to it spreading from exposure. Starline thought that Eggman had accounted for this possibility, but the latter stated that he would work out any errors after the spread was finished since the virus was working anyway. Starline protested that the virus could get out of control, but Eggman snapped back, saying that he would find a way to control it. Annoyed with Starline, Eggman ended their conversation and went off to eat. Afterward, Eggman began heading towards Sunset City in the Faceship. Arriving at the city, the doctor and his lackeys were able to create another Zombot outbreak.

The Last Minute
Soon, after Starline and Eggman agreed to use tight-band, localized attempts with a frequency to control the Zombots again, the duo left the Faceship and went to test frequencies on the Zombots in Barricade Town. After several failed attempts, Starline noted that it would have been wise to have a failsafe for the Metal Virus mutating beyond control. Eggman suggested that they use the Warp Topaz charged with the Chaos Emeralds and then hook it up to the Faceship. Starline refused as he already knew of the stone's sensitive traits. After Starline pointed out that Eggman was not cautious about the Zombot situation as he had not yet inoculated them to the Metal Virus, Eggman revealed that there was no cure. This shocked Starline and Eggman further revealed that he proposed not getting infected by the virus by simply not touching the Zombots. Starline brought up several worst-case scenarios to counter Eggman's logic, only for the latter to dismiss his nitpicks.

Soon, Sonic interrupted the duo's argument and questioned why Eggman went back to his villainous ways. Though Eggman gently reminisced on his past life, he told Sonic that he believed what he was doing currently was better than what he did as "Mr. Tinker" and that he had no plans to stop the Metal Virus. This infuriated Sonic and prompted him to fight the doctor. Soon, Eggman gloated to Sonic, saying that his time would soon run out and he will be too tired to run off the Metal Virus' effects. From this, Sonic attempted to grab Eggman and infect him with the virus but the doctor dodged him; this resulted in Eggman and Sonic falling to the ground below and soon finding themselves surrounded by Zombots. Before Eggman could get infected, Starline used the Egg Mobile to find a working frequency that commanded the Zombots to attack Sonic only. With this, a pleased Eggman ordered Starline to upload the frequency to the Faceship. Before the platypus could do anything, Sonic burst out from the Zombot horde and destroyed the Egg Mobile. Eggman quickly grabbed onto Starline's own transportation machine for a swift retreat. However, due to the added weight, the contraption crashed down onto the Barricade Town gate.

As Eggman berated Sonic for his interference, Starline suggested that they retreat to the Faceship so that they could try something else. Starline used the Warp Topaz to create a portal to the Faceship for himself and Eggman to go through. Back aboard the Faceship, Starline said that he was unable to upload or memorize the working frequency; however, he was able to recall the range. To Starline's dismay, Eggman did not care to do anything about this; with close-range broadcasts being too risky and the Metal Virus likely adapting to resist it, he did not want to repeat the tedious process just for another failure. When Starline asked what the next move is, Eggman said that he will start by enjoying their next outbreak, asking for the Faceship's current location. Orbot reported that they were above Spiral Hill Village, and the Metal Virus had already been deployed. Satisfied by the news, Eggman announced that he will figure out his next move later. Later on, Starline told Eggman that he has a solution to controlling the Zombots once again, which Eggman dismissed and demanded that he stop pestering him about it. Instead, Starline used the Warp Topaz to bring his solution onboard the Faceship; the Deadly Six.

All or Nothing
Upon seeing the Deadly Six, Eggman immediately sent Metal Sonic to attack them. Zavok swiftly used his electromagnetism to control the robot and tauntingly reminded Eggman how they were able to control robots. Following this, Starline presented the Cacophonous Conch and blew into it to try and control the Zeti. Once Zazz saw that Starline had left an opening after using the conch, he headbutted him which allowed Zeena to take the conch and give it to Zavok. With Starline and Eggman defenseless, Zavok commanded Metal Sonic to attack them; however, Starline hurriedly opened a Warp Portal that transported him, Eggman and Metal Sonic away. The trio landed on Angel Island, met by Sonic, Tails, Knuckles and Amy. Before Amy attacked them, Sonic stopped her as the doctor's presence made no sense; he had Eggman explain how the Deadly Six had taken control of the Faceship due to Starline inviting them onboard. Espio came by to the group to inform them that they had gotten word from Rouge. On the Rescue Shuttle, while Knuckles and Espio kept an eye on Starline, Rouge reported that Eggman had been powering the Faceship with the Chaos Emeralds, which Zavok had now distributed to the rest of his team and then sent them out into the world. After Rouge revealed to Eggman that she snuck onto the Faceship a few days prior and planned to steal the Chaos Emeralds before the Zeti showed up, she went on to say that she was coordinating with Orbot to spy on their deployments and coordinate their counterattack. When Eggman began to gloat over his genius in his robots, an argument broke out between him and Tails over a cure for the Metal Virus, with the fox noting that he was close to making a cure himself before it was lost to Zombots. Eggman clarified that he did not need to have one as his research found that as the Metal Virus mutated, it became unsustainable; soon, every Zombot would disintegrate approximately two hundred years into the future. An injured Silver came onboard and confirmed this claim as it described his current future well. Amy rushed to Silver's aid and asked where the survivors from Ice Paradise were, only for him to report that the shuttle went down to the Zombots and he could not save anyone; when Silver thought his time may be doomed because of his failures in the present, Eggman asked if he was always this melodramatic only to have Amy snap back at him, saying that he did not get to judge.

Later outside, Eggman and the others tried to come up with ideas on how to counteract the virus. When Amy suggested that Sonic go Super Sonic to combat the virus, he reminded her that the Deadly Six had the Chaos Emeralds. Amy told him that they had to take things one step at a time and she did not hear him coming up with any bright ideas. The doctor stated that he wanted everyone to exhaust themselves of bad ideas first and presented the idea to use the Warp Topaz, as if they had Super Sonic charge it with his power, they would be able to warp the virus away with one swoop. When Amy ironically pointed out that the Deadly Six had the Chaos Emeralds, Eggman quoted her saying "One thing at a time." Starline protested against it due to its instability and suggested putting in the work on their safe haven to find another way to solve their problem and win. Eggman reminded Starline that Sonic did not have long and since he did not want the Deadly Six using his genius against him, he wanted to end things his way. Starline again refused and decided to leave and create a solution on his own; instead, Eggman had Metal Sonic restrain Starline so that he could remove his glove that had the Warp Topaz attached to it, fired him and had the robot throw Starline out via a Warp Portal. Following this, Eggman surmised that Rouge would be able to steal the two Emeralds that were on the Faceship from Zavok; Espio noted that it left five Zeti left to deal with but Silver felt confident that they would be able to overwhelm them so long as they had each other. The group realized that they would have to split up and ambush the Deadly Six all at once since there was a risk that one could contact the others should they get a sense of their plan. While Eggman thought to work on a "Multi-Portal Generator" to help the others reach their destinations, Tails thought it would be better if each person had backup in case someone turned into a Zombot; this prompted Amy to call in the Babylon Rogues to increase their numbers.

Appearance
Dr. Eggman is depicted as a human with a rotund and burly appearance, his torso and head coming together in an egg-like shape. He possesses no visible neck, a bald head, a bright red nose, and a very bushy mahogany moustache. He also has long, almost disproportionately thin arms and legs.

For attire, Eggman wears tinted, navy blue pince-nez glasses and green-lensed goggles as headwear and an elegant, red coat sporting two square metal buttons on both sides of the chest in gold. These buttons have white straps that run across the coat's sides to identical buttons on the back. The coat also has silver, zipper-like linings down the back, arms and front, yellow cuffs, and two extensions on the front that have large silver buttons. In addition, Eggman also wears white, cuff-less gloves on 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.

After losing his memory and gaining the new alias "Mr. Tinker", Eggman began to wear green overalls, a pink shirt, and pink and green slippers.

Personality
Dr. Eggman is an evil and megalomaniacal genius who is constantly planning to take over the world and those beyond his. Showing contempt for how "filthy" and "irregular" the world is, he views himself as obligated to perfect it by ridding it of what he deems as imperfections, including free will. Arrogant, raucous and narcissistic, he prefers to show up and claim responsibility whenever he is carrying out his villainous deeds and make himself known to his enemies after he comes back from a defeat; as put by Sonic, subtlety is not Eggman's forte.

Eggman is a very short-tempered and domineering man, which makes him rather intimidating. After regaining his old memories without being able to recall the events leading up to that point, Eggman's first actions were yelling out in anger for an explanation before taking control of everyone around him. He is also rather anti-social, as seen by how limited interest he takes in others until they can prove useful to his plans and by how he treats his aides Orbot and Cubot as his servants. He also has little tolerance for failure (especially his minions' failures) and stupidity. Having no honor either, Eggman is likewise depicted as having almost zero compassion and regard for others than himself and will use and manipulate his minions and lackeys however he sees fit without a pang of remorse, not caring about ideals such as loyalty. Noticeably, he tricked Rough and Tumble into turning themselves into Zombots despite the skunk brothers being "perfect minion fodder" for him and that he owned them a deal for helping him back to his senses while he was an amnesiac.

Perhaps Eggman's most noticeable trait, is his refusal to give up. No matter how many defeats he has suffered over the years, he always has another plan ready and refers to his defeats as little more than setbacks. However, he can be so overly obsessive about achieving his goals that he either overlooks or fails to take into account some important factors, like when he hastily began implementing his Metal Virus for his next plan despite only having some minuscule data samples on it. Even in case his plans veer off course, Eggman remains unconcerned by whatever complications it might bring, certain that his genius will allow him to find a way to regain control over it.

As Mr. Tinker, Eggman displayed a very different disposition, being a friendly, humble and modest man who loved children and helping others out. Mr. Tinker also displayed a somewhat cowardly streak, being afraid of his own [./https://sonic.fandom.com/wiki/Badnik_(IDW) robots], although it did not keep him from helping and comforting the innocent.

Powers and abilities
Eggman is a brilliant scientist and inventor with seemingly limitless mastery over technology. His remarkable skills as an engineer and programmer are best evidenced by the armies of robots, machines and mechs he has created for his numerous schemes. He is also an incredibly skilled pilot: able to manipulate many different kinds of his own mechs, robots and vehicles in difficult battles with Sonic.

Dr. Starline
Dr. Starline is a kindred spirit who admires Dr. Eggman's work. It was for this reason that Starline helped Eggman back to his old self when he suffered from amnesia. After regaining his memories, Eggman took little interest in who Starline was, although he liked that Starline knew his place when he introduced himself to him. As Starline continued to reveal his worth and the measures he had taken to help him however, Dr. Eggman took more interest in him. By the time Starline presented Eggman with the Chaos Emeralds, Eggman had become thoroughly impressed with Starline and accepted him as his new minion, claiming that he was his "best lackey yet".

In no time, Starline became a high-ranking minion to Eggman, namely in how he assisted him with his experiments involving the Metal Virus. However, while Eggman is impressed with Starline's tenacity, he does not respect him enough to care for his opinions on the matters involving his work, his plans for world domination, or his inventions, as he sees himself as the superior of the two of them. Eggman's opinion about Starline was later strained when the villanous platypus took measures to kill Sonic himself, an honor of which Eggman has reserved for himself, and in the "wrong way" no less. As the Zombot hordes later began growing out of control, Eggman would scoff Starline's concerns, showing that he has no interest in Starline's viewpoints. Starline's apprenticeship was officially terminated after Eggman discovered that he went behind his back to recruit the Deadly Six. Seeing it as an act of betrayal and no longer finding his services required, Eggman took the Warp Topaz, fired Starline, and had him thrown off of Angel Island via a Warp Portal.

Orbot and Cubot
Orbot and Cubot are Dr. Eggman's aide robots, who serve as his foremost assistants and servants. Despite showing Eggman nothing but loyalty though, Eggman often mistreats them, both emotionally and verbally. In fact, nothing cheers Eggman's more up than threatening to dismantle Orbot and Cubot.

Sonic the Hedgehog
Sonic the Hedgehog is Dr. Eggman's arch enemy and the one who keeps throwing a wrench in Eggman's plans for world domination. Possessing a great dislike for Sonic, Eggman will gladly work towards the goal of making Sonic suffer and ensuring his demise. At the same time however, Eggman is not out to simple destroy Sonic (which he clams he can do at any time he wants), as he believes that is not enough or the point of their feud. Rather, he wants to beat him and prove himself the superior to the hedgehog before trying to outright vanquish him. He similar believes that he alone is entitled to destroying Sonic, and he gets especially enraged when others try to do that.

When he suffered from amnesia and became a reformed handyman named "Mr. Tinker", Eggman, being unable to recall his past hatred for Sonic, would show the Blue Blur nothing but hospitality and friendliness. Although Sonic initially refused to believe that Eggman had had a change of heart, thus making him to reject Eggman's attempts to show him friendliness, he eventually came around and managed to strike a friendship with the doctor. With Eggman's return to his old self however, the doctor forgot the friendship he and Sonic established.
