Doctor Eggman (Sonic Boom)

"I'll be back! With a new robot! Who has an accurate name! And super laser eyes! And he'll feed me ham! Evil ham..."

- Dr. Eggman, "The Sidekick"

Doctor Eggman is the primary antagonist of the Sonic Boom series. He is a human scientist referred to as the most powerful supervillain in the world, and is the arch enemy of Sonic the Hedgehog. Feared around the globe and with unlimited resources at his disposal, he seeks to conquer the world and enslave the population. From his island fortress, he concocts many evil plots and schemes against Team Sonic, a group of heroes who always thwarts his plans.

Concept and creation
When developing the character designs, the designers went with a very formal, military-esque attire for Eggman to emphasize his vanity and concern for his own and his robots' appearances, which is an attribute befitting villains.

Appearance
Unlike his main series counterpart, who is more round around the stomach, Dr. Eggman's torso is more round at the top, and he has more smooth, yet still broad shoulder. His mustache is also shorter and smoother, and a bit darker, and his legs are slightly shorter with significantly smaller feet.

Eggman's usual attire consists of militaristic garments. He wears a red jacket with yellow cuff, a front flap attached to one of the buttons and two flap hanging from the back, blue pince-nez glasses, white gloves, a set of grey goggles with flappable green lenses, grey pants and a pair of black boots with high rims. On his right wrist he has his wrist controller.

For sleeping or otherwise slouching, Eggman wears a pink pajamas with feet, with the Eggman Industries's symbol on the front and a trapdoor on the rear. During the Eggtoberfest, Eggman wore green lederhosen with a yellow shirt, white shocks, brown shoes, and a brown fedora with a red feather.

Sonic Boom: Rise of Lyric
In Sonic Boom: Rise of Lyric, Dr. Eggman discovered the ancient Destruction Troops, whose technology far surpassed his own, and seized them for himself. Identifying their creator as Lyric the Last Ancient, Eggman planned to free Lyric from his imprisonment in his tomb to get the secrets to his technology and become more powerful.

Learning that only Sonic could open Lyric's Tomb, Eggman planned to have him release Lyric for him. Eggman thus staged a scheme that made Team Sonic chase after him in his Eggmobile to the tomb, during which he had Metal Sonic come to his aid to help content with the heroes. Near the tomb, Eggman sicced his Destruction Troops on the heroes, and watched from the sidelines as his troops and Metal Sonic forced Team Sonic into Lyric's Tomb where they accidentally freed Lyric, just as Eggman had planned.

Eggman soon found Lyric in the Abandoned Research Facility and tried subjugating him with his own Destruction Troops. To Eggman's surprise though, Lyric easily retook control over his robots, so Eggman instead offer a partnership. With Lyric having trouble with Sonic spoiling his plans for world destruction, Eggman was allowed to aid, though their partnership was nothing but uneasy. Eggman was thus sent out to stop Team Sonic and reclaim a map for the Chaos Crystals that they had stolen, but failed both tasks, although Lyric let it pass as he had anticipated his failure. The two soon tracked down Team Sonic and their Crystals, but Eggman bumbling made them lose them. While they agreed to dissolve their partnership, Eggman summoned Metal Sonic to destroy Lyric, only for Lyric to take control of Metal and had him launch Eggman away. Building the control-immune Eggman Mech and finding the Twilight Crystal, Eggman returned to overthrow Lyric, but his mech proved inadequate to fight the rogue Ancient who casually left. Eggman thus turned his frustration towards the mocking Team Sonic, but the team destroyed his mech and Eggman had to flee.

With the Eggman Mech barely functional, Eggman came to Lyric's Lair as Team Sonic fought Lyric, where he fired a missile at Lyric as he prepared to finish the heroes off. Though the effort made his mech collapse, Eggman saved Team Sonic and allowed the team to defeat Lyric for good. Not long after, Eggman found Lyric's technopathy device which had been removed by Sonic, and incorporated it into his wrist controller, laughing manically over his future plans.

Sonic Boom: Shattered Crystal
In Sonic Boom: Shattered Crystal, Eggman sent Metal Sonic after Team Sonic. When the robot found the group in Ancient Ruins, Eggman appeared on a computer screen and ordered Metal Sonic to attack the heroes, which the robot failed at.

Sonic Boom: Fire & Ice
In Sonic Boom: Fire & Ice, Eggman discovered a powerful element called Ragnium, which he started mining to use as fuel for his henchbots in an attempt to humiliate Sonic by making them faster than him, while also damaging the environment. Needing a robot to mine the Ragnium, Eggman created D-Fekt, but upon activating him, D-Fekt malfunctioned and he began using his defective magnetic powers to build himself up and defeat Sonic.

TV series
Eggman's childhood is implied to have been rough. According to himself, he wanted at first to become a traffic cop, but had to give up that dream. Supposedly, he also had issues with his mother and reportedly made some desperate attempts to earn the approval of his oppressive father. The first robot he ever made was one he called Zippie. He would eventually attend evil scientist school, though he was bullied by vicious girls while in middle school.

As Eggman rose to villainy, he would spend years battling his nemesis Sonic the Hedgehog and his crew who kept him from his goal of world domination. At some point, Eggman began the Cubot Series, but could not perfect their flawed design and started the Orbot Series instead. While the Cubot prototypes escaped his plans to recycle them, Eggman managed to make his service robots (and only friends), Orbot and Cubot.

On a regular day where Sonic pursued him, Eggman called forth Burnbot to attack him. After Burnbot lost, the doctor retreated with it. Taking Sonic's advice though, he equipped Burnbot with flamethrowers. Later, Eggman learned Sonic held try-outs for a new sidekick to replace Tails, giving him the idea to apply for the try-out himself (as Sonic welcomed everyone) and then destroy Sonic and Tails. Against Sonic's wishes, Eggman made the cut and had face Tails and Fastidious Beaver in a ground-and-air race. During the race, Eggman brought in Burnbot who made Tails crash into a frozen lake in his Tornado. There, Eggman almost got Sonic with Burnbot's flamethrowers, but Sonic was saved by Tails. With Burnbot defeated, Eggman retreated in vengeance.

In a scheme to exhaust Sonic and Tails and make them easy prey for his Obliterator Bot, Eggman convinced the duo to let him, Orbot and Cubot live at Tails' by lying that they needed a place to stay while his lair was repaired. Eggman began driving Sonic and Tails crazy with obnoxious behavior and was almost kicked out, but Amy made Sonic and Tails give him a new chance, which Eggman used to keep the duo awake all night. With Sonic and Tails exhausted, Eggman revealed his plans to Team Sonic and summoned Obliterator Bot. However, Obliterator misheard Eggman's orders and attacked his lair instead. Eggman convinced Team Sonic to help him though and they stopped Obliterator Bot, though not in time to save the lair. Eggman thus tried to live with Sonic until he made repairs, but Sonic made him stay at his lair.

While spying on Team Sonic, Eggman learned that Tails' robot UT was creating tension between them by voicing their private thoughts from the subtext of their speech. To make Team Sonic vulnerable, Eggman secretly switched UT out with a copy that said what he wanted to turn the team against themselves. As Eggman's plan went smoothly, he took a break to listen to the real UT vocalizing his self-praise until Tails arrived with a deal: he would let UT go and Tails would become Eggman's assistant. Eggman accepted it and let Tails sent a goodbye message with UT to keep his friends from saving him. Outsmarted by Tails however, Eggman found Team Sonic arriving at his lair anyway, whom Eggman had to give up to since Tails had not signed Orbot's job contract. Eggman summoned the Mega to take care of Team Sonic, but it was beaten and he returned to his lair. Upon launching an attack on the Village with his Anti-fire Bot, Eggman retreated when Team Sonic defeated his robot. Later, when Sticks sought a pet, Eggman created Cluster Bot whom he planned for Sticks to adopt and then use it against Team Sonic. The plan working, Eggman visited Team Sonic a week later and gave Cluster Bot a bone made from stolen robotics. The bone turned Cluster Bot into a larger robot that caught Sonic and most of his team, but Sticks assumed control of Cluster Bot and had him throw Eggman away.

By cheating himself into being nominated for the Awardy Award, Eggman attended the Awardies, but lost the award to Leroy the Turtle. Furious, Eggman attacked with Stuffer Bot and his minions. While Eggman incapacitated most of Team Sonic at the gala, Sticks freed her friends, who then forced Eggman to retreat. While going through his mail, Eggman discovered to his joy that his lair was considered to be in Modern Lair Magazine. While the messenger did not like the lair despite Eggman's decorations though, Eggman convinced him to come back later. To redecorate his lair, Eggman hired Amy for the task. While Eggman had his doubts at first, the messenger approved Amy's work when he returned and promised to be back with the photographer. As then Eggman took credit for the work, Amy tried to leave, but Eggman imprisoned her so she could remain his decorator. The rest of Team Sonic later came for Amy, but Eggman lied that she wanted to stay. No sooner, Eggman and his lair were attacked by all of Team Sonic, who destroyed the place as the photographer came, costing Eggman his spot in the magazine.

When getting an early meal at Meh Burger in front of Sonic, Eggman met the employee Dave who was a fan of his. Eggman took a liking to Dave and made him an intern at his lair. After Eggman made Dave his protégée however, even ignoring Cubot when he was dismantled, he told Dave to wait before he could get to the big projects. Furious, Dave locked himself in Eggman's lab and activated Eggman's doomsday device. Not to be outdone, Eggman built another doomsday device to destroy the world better. However, due to Sonic and Tails manipulating them into adjusting their devices to cancel each other out, Eggman and Dave's devices failed. Furious, Eggman fired Dave and gave his assignments back to Orbot and Cubot.

For an ambitious scheme, Eggman created Evil Cookies infused with his own DNA to feed to Sonic, but his plan backfired when Tails, Knuckles, Amy and Sticks ate them instead. Regardless, the now-evil heroes joined Eggman. Seeing the upside to having them under his command, Eggman taught the group villainy to eliminate Sonic. As Sonic came to the lair, Eggman had Sonic's friends corner him. However, Eggman's allies began fighting over who deserved the honor for catching Sonic, leaving Eggman in Sonic's need of help. Involuntary, Eggman was fed a cookie by Sonic with Sonic's DNA, giving him Sonic's powers and heroism. Together, they got the others back to normal with new cookies. Eggman now thought he would now work together with Team Sonic, but was turned back to normal because the team was not happy with the idea.

Eggman later planned a fake attack and sent Sonic a message about it to ambush him, but it failed when Sonic did not show up. He thus turned to attacking Sonic with his badniks at Sonic's Shack, which at the moment hosted the Gogobas. After losing, Eggman was convinced by Sonic and Tails that he would be unstoppable with the Gogobas on his side. After negotiating, Eggman got the Gogobas to join him, but soon realized he had been tricked as the Gogobas drove him nuts with their guilt tripping.

To boost Orbot and Cubot's moral, Eggman had them set up a surprise party for themselves. On that day, he also attacked Sonic and Knuckles with his badniks, but was defeated. He then went to town to rob a helium warehouse for the party balloons. For this, he got help from Willy Walrus, but had to escape when the police came. When the party was ready, Eggman erased Orbot and Cubot's memories so the party could still be a surprise. However, while Eggman went for food, Orbot and Cubot left to look for him. When they came back for their party though, Eggman heard that they thought he had been killed. After explaining it all, Eggman erased Orbot and Cubot's memories as a demonstration, but also any clue as to where his Eggmobile was (which Orbot and Cubot had lost).

In another attempt to destroy Team Sonic, Eggman dropped by to unleash Cowbot on them, a robot that would create a massive explosion if destroyed. Back in his lair, Sonic and Tails arrived and warned Eggman that Cowbot was now out to kill him. Plotting to use the heroes to upgrade his defenses for him, Eggman convinced the duo to help and together they got his defenses ready for Cowbot. While waiting for Cowbot to come, Eggman, Sonic and Tails bonded over roasting marshmallows. When Cowbot arrived, the defenses got gunked up with marshmallows, so they resorted to stopping Cowbot by gunking up its systems too. Amidst their victory, Eggman revealed his secret plan, only for Sonic to destroy his systems.

While fighting Team Sonic in his Octopus Bot, the tides turned in Eggman's favor when the team was caught in a rock slide accidentally caused by Tails' Unbolterizer. However, as usual, Eggman lost and he fled to his lair where his TV remote was constantly destroyed by Tails as he tried watching TV. During an laser tag exercise, Eggman then noticed that the luck balance of the universe had tipped in his favor when he won by accident. Eggman thus began an invasion of Bygone Island with the Mega, certain that his luck would protect him. Sure enough, when he was corned by Team Sonic, his luck enable him to escape. Soon after though, Knuckles came to join Eggman, but due to Knuckles having a case of bad luck, Eggman's good luck was overpowered and the Mega destroyed itself, forcing Eggman his lackeys to escape.

When a strange meteor crashed on Bygone Island, Eggman went to claim it with his lackeys. There, he met Team Sonic and raced Sonic to the meteor which swapped their minds upon touching it. With the team thinking he was Sonic, Eggman planned to use Sonic's power to destroy them. Before his plan could commence though, Sonic (in Eggman's body) showed up to explain what happened. Naturally, no one believed him and Eggman got the team to drive him off. However, Eggman's cover was blown when Sonic returned with Eggman's army and Tails arrived with the meteor to verify Sonic's claim. Eggman refused to give up Sonic's body, but he soon swapped back after Sonic threatened to clip off Eggman's own mustache.

After a series of losses to Team Sonic, Eggman began losing confidence, but soon stumbled upon Soar the Eagle's life coaching seminar and hired him. Under Soar's guidance and rebuilding with small successes, Eggman's esteem was renewed. In his arrogance, Eggman fired Soar in the middle of his seminar, but soon found himself unable to make decisions anymore and lost all motivation, much to Sonic's shock when he visited. As Sonic drove his friends nuts over not having anything to do, the rest of Team Sonic tried to re-motivate Eggman into battling Sonic again. Though the plan failed, Eggman was still re-motivated by Sonic's impudence and their conflict began anew. While playing a game, Eggman discovered that Tails had joined the annoying Lightning Bolt Society. Not fond of the idea of this group working with Sonic, Eggman crashed their initiation ceremony, only to discover that Sonic and Amy were only there to get Tails. Eggman tried getting the Lightning Bolts to attack Sonic, but when that failed, he was swarmed by his fans in the group, allowing Sonic and his friends to leave.

As Eggman was defeated in his Moth Bot by Sonic, he feigned having broken his neck and sued Sonic for needlessly injuring him. For the ensuring trial, Eggman hired T.W. Barker as his lawyer and thanks to his machinations and Knuckles' incompetence as Sonic's lawyer, Eggman almost won. When Amy intervened though, Eggman's bluff was revealed, costing him his case, so he resorted to fighting Sonic instead. In a plot to take over the village's electronics, Eggman disguised robots, designed to turn appliances into weapons, as sauce cans for his tomato sauce which he began selling. Team Sonic noticed this, but Eggman tricked them when they thought the sauce was the problem. Once he had sold enough cans, Eggman initiated his takeover while he was on the Comedy Chimp Show. During the show, Team Sonic came to the lair to stop Eggman, but they were outmatched by his evil can robots. However, Eggman lost his controls to Tails, who stopped the robots. Eggman then accidentally foiled his evil plan by gloating about it in front of a live TV camera, leaving him with thousands of unsold cans.

In a scheme to turn Sonic's speed into his weakness, Eggman faked a horrible noise whenever Sonic ran, tricking everyone into thinking Sonic had a problem that restricted him from running. When Sonic was at his lowest after being kept out of a Crab Bot attack, Eggman, who claimed he was not behind the Crab Bots, offered his help after sympathizing with his situation which Sonic accepted. Eggman gave Sonic new shoes, telling him they could mute the noise he made, but were actually devices that turned his speed into power for his Giant Robot. Eggman soon after attacked Team Sonic with Giant Robot which grew stronger the more Sonic ran, but his plans were ruined when Sonic overloaded the robot with power by running faster. Awakening to a rather annoying morning with Orbot and Cubot, Eggman later used his new Egg Tank to attack Team Sonic. During the battle, when the Egg Tank's weapon was deflected back at him, Eggman countered it with another weapon, accidentally creating a time loop that endlessly repeated the day. With Eggman remaining aware, he used this loop to perfect his capture Sonic with his Egg Tank, only for the loop to reset it. Eggman tried to solve the time loop, but needed Team Sonic's help. After many do-overs, Eggman got Tails to find a solution: create a container which only Knuckles was strong enough to move to seal the loop. After several more loops, Eggman got Knuckles to follow the plan and finally broke the time loop, which Eggman celebrated with Orbot and Cubot.

From surveillance, Eggman found a Granifier Giganticus whom he wanted to enslave. Deploying Orbot and Cubot to capture it, Eggman joined them in the Eggmobile and tried to bind the giant with Bee Bots, but failed. Sonic, who protected "Rocky," then got the Bee Bots to attack Eggman. Retreating, Eggman tried to unwind in his mediation garden when Team Sonic lured Rocky there and made it fall asleep to horrible music, which Eggman had to accept, or Rocky would go on a rampage.

When fighting Team Sonic, Eggman fled into Buddy Buddy Temple with Sonic on his tail. There, the two fell through a floor, damaging Eggman's Eggmobile and injuring Sonic. Trapped deep inside the temple and unable to get out on their own, Eggman worked with Sonic to escape the temple and its death traps. While clearing a trap though, Eggman betrayed Sonic and almost left him to be crushed by a trap, but then realized he still needed Sonic's help to get out and saved him. As temple then began to cave in, Eggman and Sonic found a way out as their allies arrived and got everyone to safety. Agreeing to stay as enemies despite their good teamwork, Eggman and Sonic parted ways. Eggman later met a computer virus named Nominatus, whom he became such good friends with that he let him in on his lair's schematics, though his callous behavior drove Orbot and Cubot away. The duo soon returned to warn him that Nominatus plotted against him though. To Eggman's surprise, Nominatus revealed he had taken over all his tech to destroy all life forms. Now running from his own robots, Eggman sought Team Sonic for help and joined forces with Tails. While the others provided cover, Eggman and Tails sent Orbot and Cubot into cyberspace where they stopped Nominatus. The doctor then promised Sonic a fight next week and left.

Going to Meh Burger on the day after fighting Sonic, Eggman saw Sonic had cut in front of a Motobug holding his spot. Furthermore, Sonic bought the last chili dog, so Eggman had him get another. However, because Sonic forgot the relish, Eggman hunted him down with his minions, only to be defeated when Sonic's team came to his aid, though not without making a parting attack with the Eggmobile. Some time later, as Eggman was in his office, his lair was hit by one of his own missiles, which had been launched by Amy and Sticks.

After spying on Team Sonic with Fly Bot, Eggman went to destroy them, only to fall for a prank Team Sonic lured him into by misleading Fly Bot. Blaming the folly of machines, Eggman deserted technology (except Orbot and Cubot) and his lair to start a tech-free life while trying to beat Sonic. Later, Eggman was sought out by Sonic as the island got attacked by his missiles and robots, but Orbot revealed the Lightning Bolt Society were behind this, who had seized Eggman's lair. While Eggman did not help much at first, he joined Team Sonic after the Lightning Bolts shut down Orbot and Cubot remotely. Outsmarting the group over the surveillance, the allies drove them away, and Eggman returned to his lair. Eggman later went to Meh Burger for lunch, only to go to Chez Amy after getting sloppy service from Dave. Hearing that Amy shared his view on Meh Burger, they made a partnership to bring Meh Burger down, where Eggman blew the establishment up. To Eggman's dismay, Amy took pity on Dave and hired him, who gave Eggman the same old sloppy service. Eggman thus sent his badniks to kill Dave, but Team Sonic stopped them, although the battle destroyed Chez Amy.

Seeking to fulfill his dream of making an evil amusement park, Eggman made several Swifty the Shrew robots to get Sonic banished from the Village. Once they succeeded, Eggman arrived to gloat at the villagers as his Swifty robots ravaged the Village. However, the Village Council undid Sonic's banishment, who then sent Eggman flying and stopped his robots. Taking the advice of his accountant to diverse his business, Eggman sought out Monkey-Boy to have him work as his curse-breaker. Being rejected, Eggman tried forcing Monkey-Boy to join him with his badniks, but Team Sonic, who was visiting Monkey-Boy, defeated the robots and made Eggman retreat. Eggman later attempted another plot where he tried turning the island's coconuts into bombs with his Spider Bombs but was foiled by Team Sonic. He soon after came to Sticks' yard sale to shoplift a comic (among other things), but was caught by Sonic until he paid up. However, his comic got destroyed by a stray Spider Bomb.

As his trash began to pile up, Eggman went to city hall to complain, only to find Knuckles as the deputy mayor, whom was impossible to complain to. Seeing the Village in chaos from Knuckles' reckless permits, Eggman became envious and joined up with Team Sonic to stop Knuckles. When they faced Knuckles, his approval stamp ran out of ink, which Eggman then took to seize control over the Village. Despite his robots' aid though, Eggman lost his chance to fix his garbage issue when the stamp was destroyed by Team Sonic and Mayor Fink resumed his position. In a multi-layered plan, Eggman began making a movie that could enslave its audience. While shooting it, during which Sonic and Tails ruined his scene with his robots, Eggman offered Sonic to play himself for his movie so to distract him. Though Sonic declined at first, he accepted once Eggman had his caterer Dave cast as Sonic. During the filming though, Eggman rejected the changes Sonic made to the script, making Sonic leave. Needing him for one last scene through, Eggman got Sonic to perform his battle against Drill Bot by making him think he was up to something. At his movie's premiere however, Eggman realized he had forgotten to install his mind-enslaver device in the camera and had everyone leave so he could watch his movie alone.

Eggman later launch two attacks which were stopped by Team Sonic. During the first, he was shocked to hear Sonic called Mike the Ox "just a guy," and during the second he accidentally shot Cubot out of the Eggmobile and injured Mike. Later through Fly Bot, Eggman heard from the Lightning Bolt Society that Sonic had retired and Team Sonic was out of town. Rather than risk Sonic returning to fight him, Eggman ignored his lackeys and waited for the time to strike. When Sonic halted a sheep stampede, Eggman then launched a sneak attack in the Eggmobile with Orbot and Cubot. However, their attempt was foiled when Mike warned Sonic, who used the Eggmobile to herd the sheep and disorient the evil trio before defeating them. Another time, Eggman caught one who seemed like Knuckles when he attacked his lair. As Eggman saw this Knuckles flicker though, Team Sonic came to explain that this Knuckles was from another dimension. Knowing this Knuckles' presence put their dimensions at risk of imploding, Eggman released him and gave the heroes the tech to get him home.

When the Cubot prototypes began stealing tools, Eggman had to explain his innocence when Sonic and Tails accused him as the culprit. Having also been robbed, Eggman sent Orbot and Cubot to find the prototypes. When Orbot reported back that Cubot had joined the prototypes, Eggman probed Orbot for their location and tried destroying them to keep Cubot from spilling any secrets. His attack failed thanks to Sonic, Tails and Cubot, and he returned to the lair to put Orbot and the rejoined Cubot to work. Later on, Eggman saw Dave the Intern's failed attempts to be a villain, whom he condescend to and bragged about his new Electrocage. However, when Dave accidentally knocked out Eggman out, the doctor was imprisoned in his own cage by Dave, who then hijacked Eggman's forces to become the top villain. Eggman was soon after rescued by Sonic (though the doctor was too prideful to accept it at first) and reluctantly told Sonic how to stop Octopus Bot, who Dave currently misused. Once Dave was beaten, Eggman retrieved his battered robot.

On New Year's Eve, Eggman, after he failed to beat Team Sonic with his Ball Bots, moped that he had yet to keep his resolution of beating Sonic just once this year. At Orbot and Cubot's party though, Eggman made a Slow Motion Machine after seeing Orbot's slow-cooked roast to get more time to beat Sonic. Using it in the Village Center to slow down time, Eggman made the partially-immune Sonic face him in several games as the Slow Motion Machine halted his weapons. After several loses and voicing his motives, Eggman finally beat Sonic in a game (unaware that Sonic purposely lost). Eggman restored time to gloat of his victory, but nobody believed him since it happened too fast, though he got some comfort from Sonic.

Having ordered a Background Music Generator to spice up his attacks, Eggman attacked Leroy the Turtle and the post office with Decimator Bot when they failed to deliver his package. However, Team Sonic stopped Eggman, forcing him to go through several troubles to get his package. Meanwhile, Eggman saw Tails' horrible attempts to get Zooey's attention until he (in accordance to the "bro code") told Tails to just be himself. Once he got his generator, Eggman started an attack which Tails stopped. Seeing Tails had won Zooey over thanks to his advice though, Eggman sat a romantic mood for them. Eggman later caught Sonic entering Bro-Down Showdown to win a new couch for Amy and decided to use this. Joining the game show, Eggman let himself get paired up with Sonic for then to have Obliterator Bot attack the Village; if Sonic fought Eggman's robot, he would be disqualified from the show for fighting his partner. Despite Eggman certainty of Sonic choosing to continue the game, his plans were ruined when the hedgehog chose to stop his robot.

When Knuckles became a celebrity, Eggman offered to sponsor him so to market Eggman Industries, but was ejected. Later, Comedy Chimp sought his help removing Knuckles as host for the Comedy Chimp Show, which Eggman accepted once he was promised to sponsor said show. Eggman thus sponsored an attack on Knuckles at the studio with his robots, but was forced to retreat when Team Sonic reunited against him. Eggman later tried framing Sonic as a thief by having Metal Sonic rob the Village. When Metal then stole Eggman's Particle Accelerator, Eggman called in the police and Sonic, where he marked Sonic as the thief using false clues. While Eggman tried twice to get Sonic arrested, Sonic, Knuckles and Earl proved Sonic's innocence by bringing in a beaten Metal Sonic and the stolen goods. Playing innocent, Eggman took his creations back.

With the arrival of the Robot Battle Royale, Eggman joined the tournament with a robot of his own and easily made it to the finals where he faced Tails' Hypno-bot. Having stolen Hypno-bot's override code though, Eggman took control of Tails' robot and won the match. Eggman then went to Tails' Workshop to take over Tails' inventions using Hypno-bot's robot manipulation abilities to create a new army. However, his plans failed when Tails retook control of Hypno-bot and made Eggman's robots dance, making Eggman flee in shame. During a heat wave, Eggman began harnessing solar power which he used to super-charge his Badniks and sic them at the Village. However, this alerted the Archipelago Homeowners Association to his illegal robot housing. To avoid eviction, Eggman hid his robots while he had the association over for dinner to prove he had no robots. However, a power overload made Eggman's robots go nuts and expose his fraud despite his efforts, so he imprisoned the association instead. When Team Sonic freed them however, Eggman convinced the association his robots were actually art, although he would spent the whole night fixing them.

Becoming a Fuzzy Puppies collector, Eggman bonded with fellow game enthusiast Amy during a fan meeting. Forming a part-time friendship, they spent their free time together playing Fuzzy Puppies, with Amy turning Eggman into a top player. Although Team Sonic eventually discovered them, Eggman came with Amy to Puppy Con where he distracted everyone with a rockslide he blamed the Lightning Bolts for while he stole a rare game piece from the Walrus Child. Caught in the act, Eggman played Amy for the game piece, which he returned after losing so to keep his friendship with Amy, who threatened to end it. Hoping to demoralizing the Village by raiding its toy-and-game factory, Eggman was stopped by Team Sonic. Calling five-against-one unfair, Eggman convinced the team to fight him one-on-one. Using manipulation, Eggman fooled the group one by one while stealing their gear (he made Knuckle make him a component) which he used to capture Sonic during their face-off. However, the rest of Team Sonic then arrived and worked together by switching out when needed to defeat Eggman and his stolen gear, leaving him encaged with Sonic (the group paying Sonic back for his snarkiness).

During a test of his new Obliterator Bot in the Village, Eggman was beaten for the millionth time by Team Sonic. Jealous that the team got an award for this, Eggman wanted one himself. When the mayor would not give him one, Eggman stole one instead. To Eggman's fortune, when Team Sonic tried to stop him, their image specialist kept them from attacking him. However, Sticks got the team's act together and Amy sent Eggman flying. Eggman later came to see a fight between Knuckles and the new supervillain Charlie, with the novice villain getting defeated, much to Eggman's chagrin.

Eggman eventually called all the local villains and rogues to his lair, including Shadow the Hedgehog (much to Eggman's glee), to form a team under his leadership to destroy Team Sonic. Since the others wanted to lead though, Eggman had them do team exercises, making the disgruntled Shadow leave. Though depressed over their loss, Eggman was re-inspired as his group agreed to his leadership. At the attack, Team Eggman split Team Sonic into different fights, leaving Eggman, Giant Robot and Charlie to face Sonic. When Eggman stood to lose though, Shadow came to destroy Sonic himself. Geeking out, Eggman accidently ruined Shadow's fight. With Team Sonic regrouped and Shadow having left, Eggman was thrown around by the heroes as payback.

The Big Boom
At some point, Eggman planted the Rock-cyborg beneath Tails' house. Later on, Eggman fought Sonic with his Big Boy, until Tails, Knuckles and Amy came and helped beat the mech, forcing Eggman to retreat. The next day, Knuckles arrived at his lair and wanted to join him, after having an argument with Amy. Accepting Knuckles' offer, Eggman patched up and upgraded the Big Boy to engaged Team Sonic again. This time though, he distracted the team, which allowed Knuckles to attack and capture his teammates, with the exception of Amy, whom Eggman captured with the mech. With the trapped heroes onboard the Big Boy, Eggman headed towards the local village, though uncertain of what to do with it. However, he was betrayed by Knuckles, who had remained loyal to his teammates the entire time and got rid Eggman's lackeys. As Knuckles tore the Big Boy apart, Eggman retreated while his prisoners escaped.

Returning to his lair, Eggman had Orbot and Cubot repair and upgrade the Big Boy. Eggman soon took off in his mech to attack the island again, unaware of the Big Boy's lack of proper structure, caused by Orbot and Cubot's fight over the piko hammer. No sooner, the piko hammer ricochet out of Eggman's mech which caused it to fall apart. Repairing and upgrading the Big Boy once more, Eggman agreed with Team Sonic to have a showdown on the beach. However, when Team Sonic forgot to show up, Eggman tracked them down in the Big Boy with Orbot and Cubot. Engaging Team Sonic in a fight, his Big Boy proved more than a match for the heroes. Amidst the battle, Sticks showed up with a weapon to defeat Eggman, which worried him, but when she revealed the weapon to be a rock, Eggman threw a tantrum and considered going home until Orbot restored his resolve. However Eggman was defeated when Sticks threw the rock at the Big Boy, where it ricocheted into the mech and destroyed it. As such, Eggman, Orbot and Cubot retreated to their lair, where Eggman revealed to Orbot and Cubot that he had another creation ready for Team Sonic.

Boom Shaka-laka
As Eggman tried selling a bridge to destroy in the Village Center but failed, he realized that to better pull off his schemes, he had to earn the villagers' trust. When he failed to earn it by showing goodwill and had a brief skirmish with Sonic who mocked him, Eggman set up the Eggtoberfest carnival to buy the villagers' trust. He was nearly attacked by a mob when he realized he forgot to hire operators for the rides, but he convinced Team Sonic to fill in. However, when it turned out the villagers were not buying it, Eggman set his army loose on them in vengeance, only for it to be destroyed by Team Sonic. Amidst the ruins though, Eggman encountered Comedy Chimp who gave him the idea to challenge Team Sonic to a go-kart race so he could get their bio-data for Project Hodge Podge.

Deploying his Courier Robot to Team Sonic, Eggman contacted the heroes over the robot's video phone and challenged them to a supposedly fair race in his Go-kart Pan-island Grand Prix. Though Sonic refused, Eggman goaded him into accepting on behalf of the team. At the race, Eggman provided Team Sonic (excluding Sticks) with go-karts and allowed them to take the lead while his Bio-scanning Who-za-ma-whats-its copied their bio-data. While getting the data, Eggman incapacitated the racers with traps and robots until only Sonic was left, whom Eggman dropped into a ravine on a rigged bridge while he headed for the goal. However, Sonic returned, and despite launching all his traps, Eggman could not keep him from taking the lead. Eggman thus engaged his Spider-Kart and kept Sonic from the goal. However, Tails, Knuckles and Amy then attacked him in Tails' Plane, distracting him enough for Sonic to win. Having lost because he broke his own rules, Eggman was surprise-attacked by Team Sonic who destroyed his Spider-Kart, leaving him to flee on his mangled vehicle.

Following his Mebot's humiliating loss to Sonic, Eggman ordered a gorilla as a henchman for a new approach. When Eggman received the gorilla though, it thrashed him and his lair, forcing Eggman to get Sonic to remove it. Eggman later saw it perform on TV and was so impressed with it that he ordered a new one. Eggman later lost a earpiece and suspected Team Sonic took it, making him monitor them for clues. When that proved fruitless, Eggman found his earpiece when he accidentally stepped on it. He then received the new gorilla he ordered, only for it to beat him up too.

Personality
Dr. Eggman is a short-tempered, ego maniacal, raucous and pompous evil mastermind. He has all the qualities of a classic villain: he looks, talks, and dresses like a bad guy and has selfish and unmotivated dreams of conquering the world, the destruction of his enemies or both. A would-be tyrant, he has a hunger for power and desires as well attention, adulation and a little respect. He holds a high view on himself which makes him incredibly arrogant, such as denying his past failures and justifies his terrible actions. Driving by a constant desire to ultimately enslave the entire world, he is determined to do whatever it takes to achieve his goals, even if that means causing meaningless destruction, getting into otherwise awkward situations or joining an enemy more powerful than he is. His uncaring personality is mostly due to his over-inflated ego, as he only views himself with utmost pride.

Matching his arrogance, Eggman is rather vain. He is very concerned with how he and his robots look like and takes great pride in his mustache, which he grooms professionally and would give up his chance at power to preserve. Despite having unlimited resources at his disposal, Eggman can be rather stingy as he refuses wasting more money than needed and always complains when he thinks his money are going down the drain. Also, while sometimes showing the tendencies of a neat-freak, Eggman actually has poor personal hygiene.

Eggman is a complicated guy when it comes to his relationships. While contradictory to his previous villainous exploits against them, Eggman has no trouble cutting loose and having fun with his enemies whom he can show a sincere fondness of. In the case of Amy, he remains her enemy, but in their free time they are "Fuzzy Puppy buddies." Though this comradely behavior is sometimes a front to exploit his enemies, Eggman is willing to provide genuine help his enemies as he believes the "bro code triumphs the enemy code."

In spite of his smarts, Eggman is deranged, immature and buffoonish in behavior, and his schemes are usually more zany rather than threatening. While his pride and arrogance are his core parts, they are also his greatest weakness, as they make him far too overconfident and a blabbermouth which ultimately leads to his downfall. Excessively self-deluded, he thinks others secretly admire him and only mock him out of jealously. When in situations over his head though, he is willing to abandon his pride to get help. He is also laidback and is noted to be somewhat of a doofus as he misses out on great opportunities to eliminate Team Sonic, and he can pretty much only handle situations in a villainous manner. Because of all his flaws, no one really considers him a true bad guy; however, this also works in Eggman's favor as people tends to underestimate him, which makes him an unpredictable opponent. Eccentrics aside, Eggman is still a highly intelligent and manipulative individual under the right circumstances who can play his foes right into his hands. Also, while things might not always work out for him initially, he is always working behind the scenes to get the upper hand and come out on top.

Powers and abilities
Eggman is a brilliant scientist, mechanic and inventor whose mastery of technology is nearly boundless, able to create all manners of machines, mechs and robots, and doomsday devices capable of undoing creation. According to Orbot, he is the greatest genius that has ever lived. His remarkable skills as an engineer and programmer are best evidenced by the armies of robots and weapons he has created for his numerous attempts at world domination and destroying Team Sonic, some of which he has been able to build and program in a very short time. He is also a very skilled pilot, able to manipulate many different kinds of his own mechs and vehicles in difficult battles with Team Sonic.

Another of Eggman's skills is his masterminded plots, manipulations and schemes which nearly always succeed in some way. However, even when successful, his plans usually fail due to Sonic and his friends and his own arrogant overconfidence. Physically, Eggman severely lacks in stamina, unable to run very long before he is exhausted. However, he has above average strength, being able to break a ping pong table with one hit. He is also noted to be surprisingly agile for his age, and he has fairly good reflexes as he could dodge laser fire from five opponents at the same time during an exercise.

After eating an Evil Cookie infused with Sonic's DNA, Eggman acquired Sonic's powers and moves, including his super speed, agility, reflexes and spin attack. However, he lost these powers after being restored to normal.

Equipment
Dr. Eggman wields a wrist controller that is equipped with a device that originally belonged to Lyric. This wrist device lets him manipulate anything electronic that is not manually controlled. In addition, it can fire various types of beams, like lasers, force-field beams and teleportation beams It also has some more novel functions, like an alarm for schedules and a music player.

Sonic the Hedgehog
Sonic the Hedgehog is Dr. Eggman's arch enemy, whom he has fought for years, and many of his schemes centers around ensuring his destruction. However, their relationship is rather complex. When fighting, Eggman is very hostile towards Sonic, showing an open sense of superiority and intend to destroy him. Outside their fights however, they are much more relaxed, allowing each other to be in their presence without them going at each other's throats. Sometimes, they will even hang out together. In times whenever he finds himself in situations over his head, Eggman is also not above asking (or begging) for Sonic's help. He also often lets himself fall for Sonic's taunts.

Regardless of his dislike of Sonic, Eggman has shown a certain fondness for him and interest in being his friend, even calling themselves "bros" while camping with him. In Eggman's own opinion, just because they are sworn enemies, it does not mean they cannot be friends. Their frequent encounters has as well left Eggman with a profound knowledge of Sonic's character and his preferences, enough to get them to the finals of Bro-Down Showdown. Also, when dealing with a common threat or problem, they are willing to put aside their differences and work together, even at times showing a sense of good-spirited comradery and well-oiled teamwork. However, they both agree that they can never really be friends because of their different standpoints. More often that not though, Eggman only uses his attempts to befriend Sonic as a mean to further his plans.

For all their opposing ways, Eggman and Sonic are ultimately co-dependent and need each other in their lives. Without Eggman to fight, Sonic becomes too bored, and without Sonic to challenge him, Eggman has no motivation to be a villain and will sink into a slump of self-pity. For better or worse, their never-ending conflict is what drives them and keeps their lives balanced.

Miles "Tails" Prower
Another one of Eggman's most prominent enemies is Miles "Tails" Prower who assist Team Sonic in thwarting his plans. In spite of their mutual animosity, Eggman acknowledges Tails' intellectual prowess and is seemingly the only one Eggman considers his peer. As such, he has more than once called Tails in to help with scientific problems he cannot solve on his own, with the two of them often working in perfect sync. The two also usually join forces in the field of science when dealing with a common threat.

Eggman and Tails have at lot in common, being both inventors and highly intellectual, and, like Sonic, Eggman is not above showing some occasional fondness of him. However, they both agree that them acting like friends is awkward. Even so, Eggman is willing to give Tails genuine help as seen how he helped him get closer to his crush Zooey, even when he did not have to.

Knuckles the Echidna
Knuckles the Echidna is another of Eggman's enemies on Team Sonic who always thwarts his plans. However, he does not think highly of Knuckles. He considers Knuckles an imbecile and thinks so little about him that he does not care remembering his name which means he usually gets it wrong. Knuckles' stupidity is also a constant source of frustration for Eggman. Whenever Knuckles seemingly deflects to Eggman however, the doctor always welcomes him (presumably seeing it as a victory on his behalf), although the outcome is always disastrous to Eggman.

Amy Rose
Another member of Team Sonic who always thwarts Eggman's plans is Amy Rose. Like the other heroes, Eggman views her in general as his enemy and always tries to destroy her. While Amy is usually the most sympathetic towards him on Team Sonic, Eggman does not take kindly to her attempts to consult him or probe him about his feelings and deep-seated issues.

Amy is the only person on Team Sonic whom Eggman has established a stable (part-time) friendship with, having bonded with her over their shared passion for Fuzzy Puppies; while they agree to remain enemies on the battlefield, they come together in their spare time to play Fuzzy Puppies and normally have a great time. Eggman even willing gave up one of his plans in order to preserve this part of their relationship.

Sticks the Badger
Sticks the Badger is another one of Eggman's enemies from Team Sonic who always thwarts his plans. As thus, he seek her destruction just as often as the rest of her team. Although they do not have much interaction, Eggman thinks of her as pretty much insane, referring to her as "the crazy one."

Orbot and Cubot
Orbot and Cubot are the closest and only things Dr. Eggman has to friends and even considers them family. While Eggman on some level cares about Orbot and Cubot as he would be completely alone without them, he would never admit it and instead tells them how little they mean to him.

Most of the time, Eggman views Orbot and Cubot as unintelligent and hopelessly incompetent. Being an evil genius, he also views it as his obligation to mistreat them. He thus give Orbot and Cubot little but terrible treatment in return for the often grueling assignment he gives them, such as dismissing their company, berating them on a daily basis, having them set up their own parties, and constantly erasing their memory files. Eggman has even developed a subconscious habit of ending every random observation he makes with an insult at them, and bashing them with a magazine is one of his hobbies. While Orbot and Cubot are (mostly) loyal to Eggman, they are not perfect and they have a tendency to say things he does not want to hear.

Lightning Bolt Society
Dr. Eggman holds a great deal of dislike for the wannabe villains in the Lightning Bolt Society. Whereas the group looks up to the doctor, Eggman thinks of them as losers and dolts (for a better lack of words). He has as well been pestered by the group on more than one occasion, who has repeatedly rummanged through his trash and even once took over his his lair.

In spite of his dislike of the group, Eggman has occasionally taken a shine to some members. He likes Willy Walrus for being a honeydripper and once allowed him to join him on a robbery. Initially, he also liked Dave the Intern for his enthusiasm and admiration of him, prompting him to make Dave his intern and eventual protégée. However, he fired Dave in spite after he disobeyed him. Also, despite having sworn he would never team up with them, Eggman also let them join Team Eggman (although this was most likely out of desperation).

Shadow the Hedgehog
Dr. Eggman holds a great deal of idolization for Shadow the Hedgehog, admiring him for how popular, cool and edgy he is. In fact, when Eggman believed Shadow to have joined Team Eggman, he claimed to be "geeking out." Acting very much like a fanboy around Shadow, Eggman will anything to please him despite getting nothing but rejection in return. Eggman also clearly acknowledges Shadow's strength, admitting that without his help, Team Eggman stood no chance of beating Team Sonic.

While Shadow often voices how a bother Eggman is to him and tries to get rid of him, Eggman never seems to mind it.

Family
Eggman's family have been mentioned at various times by Eggman himself and his foes, although it is implied Eggman did not have the best of relations with them. His villainous behavior once prompted Amy to remark that he had "Mother issues" which he vehemently denied. He also claimed to have spent extra hours studying evil in an effort to impress his oppressive father.
