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 supervillain and arch enemy of Sonic the Hedgehog, who seeks to conquer the world and enslave the population, and plots evil schemes against Team Sonic from his evil fortress.

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 quite fitting for 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 a wrist controller with a touchpad interface which was original orange until it turned blue from equipping Lyric's chest device to it.

For sleeping or otherwise slouching, Eggman wears a pink pajamas with feet, with the Eggman Empire'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 hat with a 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 accidently freed Lyric, just as Eggman had planned.

Eggman soon after found Lyric in the Abandoned Research Facility and tried subjugating him into his service with his own Destruction Troops. To Eggman's surprise though, Lyric easily retook control over his robots, so Eggman instead offer Lyric to be his partner. With Lyric having trouble with Sonic spoiling his plans for world destruction, Eggman was allowed to aid him, 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 at his future plans for it.

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
While not much is known about Eggman's past, he is implied to have had a rough childhood. Supposedly, Eggman had issues with his mother and while attending middle school he was bullied by vicious girls. As Eggman rose to villainy, he would spend years batting his arch nemesis Sonic the Hedgehog and his crew who kept him from his goal of world domination.

On a regular day where Sonic pursued him, Eggman called forth Burnbot to attack him. As Burnbot lost to Sonic, the doctor retreated with it. Taking Sonic's advice, he equipped Burnbot with flamethrowers. Later, Eggman learned Sonic held try-outs for a new sidekick to replace Tails, which gave 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 drowned Sonic with Burnbot's flamethrowers, but Sonic was saved by Tails. As Burnbot was defeated, Eggman retreated in vengeance.

In a scheme to exhaust Sonic and Tails and make them easy prey for his Obliterator Bot, Eggman convinced Sonic and Tails to let him, Orbot and Cubot live at Tails' by lying that needed a place to live while his lair was repaired. Eggman began driving Sonic and Tails crazy with his obnoxious actions 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 activities. With Sonic and Tails exhausted, Eggman revealed his plans to Team Sonic and summoned Obliterator Bot to destroy them. However, Obliterator misheard Eggman's orders and attacked his lair instead. Eggman convinced Team Sonic to help him, and together they stopped Obliterator Bot, though not in time to save the lair. Eggman then tried to stay 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 translating their private thoughts from the subtext of their conversations. To make Team Sonic vulnerable, Eggman secretly switched UT out with a copy that said what he wanted to turn the team against themselves. Eggman's plan went smoothly and 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 rescuing him. Outsmarted by Tails however, Eggman found Team Sonic arriving at his lair to save Tails, who Eggman had to give up 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 creation. 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 worked, and a week later, Eggman visited Team Sonic and gave Cluster Bot, now named "Buster", a bone made from stolen robotics. The bone turned Buster into a larger robot that caught Sonic and most of his team, but Sticks assumed control of Buster and had him throw Eggman away.

By cheating himself into being nominated for the Awardy Award with Stuffer Bot, 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 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. However, the messenger did not like the lair despite Eggman's redecorating, but 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. However, as Eggman took the credit for the changes, 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, which cost Eggman his spot in the magazine.

When decidedly getting a meal at Meh Burger in front of Sonic, Eggman met the cashier Dave who was a fan of his. Eggman took a liking to Dave and made him an intern at his lair. While Eggman enjoyed Dave's enthusiasm and made him his protégée, 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 failed when Tails, Knuckles, Amy and Sticks ate the cookies instead. Regardless, the now-evil heroes joined Eggman, and the doctor saw the opportunity of having them under his command and so taught them 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 of catching Sonic, leaving Eggman in Sonic's need of help. Involuntary, Eggman was fed a cookie by Sonic with his DNA, giving him Sonic's powers and heroism. Together with Sonic, they got the others back to normal with new cookies. Eggman now thought he would work together with Team Sonic, but was turned back to normal too because the team was not happy with the idea.

Setting an ambush for Sonic, Eggman planned a fake attack and sent Sonic a message about it to lure him in, but it failed when Sonic did not show up. Thus, he attacked Sonic at his shack with his badniks, which at the moment hosted the Gogobas. After he lost, Eggman was convinced by Sonic and Tails that if the Gogobas joined him, he would be unstoppable. After negotiating, Eggman got the Gogobas to join him, but he 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. During 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 gas 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 it could still be a surprise. However, while Eggman went for food, Orbot and Cubot left to look for him. When they came back, Eggman gave them their party and heard that they thought he had been killed. After explaining everything 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, a robot the team could not destroy without creating a massive explosion, on them. Later, back in his lair, Sonic and Tails arrived and warned him that Cowbot was now out to kill him. Plotting to use the heroes to upgrade his defenses and then use them against them, 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 were 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 rockslide accidently 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 discovered 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 from Team Sonic. Sure enough, when he was corned by Team Sonic, his luck enable him to escape. Soon after, Knuckles came to join Eggman, but due to Knuckles suffering from 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 when they touched it. With the team thinking he was Sonic, Eggman planed to use Sonic's power to destroy them. Before his plan could commence though, Sonic (in Eggman's body) showed to explain what happened. Naturally, no one believed him and Eggman got them 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 loses to Team Sonic, Eggman began losing confidence. He soon stumbled upon Soar the Eagle's life coaching seminar and thus hired him. Under Soar's guidance and rebuilding with small successes, Eggman's esteem was renewed. In arrogance, Eggman fired Soar in the middle of his seminar, but he 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 to 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 that this group was working with Sonic, Eggman crashed their initiation ceremony, only to discover that Sonic and Amy only were 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 get away.

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 trial, Eggman hired T.W. Barker as his lawyer and thanks to his machinations and Knuckles' incompetence as Sonic's lawyer, Eggman almost won. As Amy intervened though, Eggman's bluff was revealed, making him lose his case, so he resorted to fighting Sonic instead. In a plot to take over with 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 discovered this, but thought the sauce was the problem, allowing Eggman to trick them. Once he had sold enough cans, Eggman initiated his takeover when he was interviewed on the Comedy Chimp Show for his sauce. During the show, Team Sonic came to the lair to stop Eggman, but they were outmatched by his evil can robots. However, Eggman lost all his controls to Tails, who stopped all the robots, and even accidentally foiled his evil plan by gloating about it in front of a live television camera, leaving him with thousand of unsold cans.

In a scheme to turn Sonic's speed into his weakness, Eggman somehow faked a horrible noise whenever Sonic ran, tricking everyone into thinking Sonic had a problem and thus restricted him from running. When Sonic was at his weakest after being kept out of a Crab Bot attack, Eggman, who claimed he was not behind the Crab Bots, came to him and 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 could turn his speed into power for his Giant Robot. Eggman soon after attacked Team Sonic with the 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 set out in his new Egg Tank to attack Team Sonic. During the battle, Eggman used his tank's weapon against Sonic, but when Amy deflected it, Eggman countered it with another weapon which accidentally created a time loop that endlessly repeated the day. With Eggman remaining aware, he used this loop to stop Amy and 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 convinced Tails to find a solution: create a container to seal the reaction which was so heavy only Knuckles could move it. Following several more loops, Eggman got a defiant 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 work for him. Deploying Orbot and Cubot to capture it, Eggman joined them in the Eggmobile and tried to bind the giant with Bee Bots, but failed, and Sonic, who protected "Rocky" got the Bee Bots to attack Eggman. Retreating, Eggman tried to unwind in his mediation garden when Team Sonic lured Rocky to the garden and made it fall asleep there 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, a place meant for bonding, with Sonic pursuing him. After getting trapped inside, the two fell through a floor, damaging Eggman's Eggmobile and injuring Sonic. Unable to get out on their own, Sonic and Eggman tried escaping together, but only fell deeper into the temple where they accidentally set off a death trap. Eggman thus joined forces with Sonic and through teamwork they escaped the trap. While clearing another trap though, Eggman betrayed Sonic and almost left him to be crushed by enclosing walls, but then realized he still needed Sonic's help to get out and freed him. As temple began to cave in, Eggman and Sonic found a way out as their allies arrived and got everyone to safety, though they agreed they should stay as enemies, and parted ways. Eggman later met a computer virus named Nominatus, whom he became such good friends with online that he let him in on his lair's schematics, though this relationship made his callous behavior drive Orbot and Cubot away. While Eggman did not notice their departure at first, they soon returned to warm him that Nominatus plotted against him. To Eggman's surprise, Nominatus confirmed it and revealed he had taken over his tech to destroy all life forms. Now running from his own robots, Eggman went to Team Sonic for help and joined forces with Tails. While the others provided cover, Eggman and Tails sent Orbot and Cubot into cyberspace to stop Nominatus. After Eggman's lackeys completed their mission, the doctor promised Sonic another fight next week and left.

Going to Meh Burger on the day after fighting Sonic, Eggman saw Sonic had cut in front of Motobug who held his spot. Furthermore, Sonic bought the last chili dog, so Eggman had him get another from the warehouse. 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 Flybot, Eggman went to destroy them, only to fall for a prank Team Sonic lured him into by misleading Flybot. Blaming the folly of machines for this, 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 was 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. By outsmarting the Lightning Bolts over the surveillance, the allies drove them away, and Eggman returned to his lair. Eggman eventually 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 sloppy service. Eggman thus sent his badniks to kill Dave, but Team Sonic stopped them, although the battle left Chez Amy in ruins.

Seeking to fulfill his dream of making an evil amusement park on the island, Eggman made several Swifty the Shrew robots to get Sonic banished from the Village. Once they succeeded, Eggman arrived to gloat as his Swifty robots ravaged the Village. However, the Village Council undid Sonic's banishment, who then defeated Eggman and his robots.

The Big Boom
At some point prior, Eggman planted the Rock-cyborg beneath Tails' house. Later on, Eggman fought Sonic with his Big Boy, until Tails, Knuckles and Amy came to Sonic's aid and beat the mech, forcing Eggman to retreat to his lair. The next day, Knuckles arrived at Eggman's lair and wanted to join him, after having an argument with Amy provoked by his Rock-cyborg's attack. Accepting Knuckles' offer, Eggman poorly 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 in his lair that to better pull off his evil schemes, he had to earn the villagers' trust. When Eggman failed to earn it by showing goodwill and had a brief skirmish with Sonic who mocked him, Eggman was inspired to 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 the positions. However, when it turned the villagers were not falling for 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 get a hold of Team Sonic, Eggman contacted the heroes over the robot's video phone once it found them and challenged them to a go-kart race in his Go-kart Pan-island Grand Prix where weapons, robots and powers were forbidden. Despite Sonic initially refusing, Eggman goaded him into accepting on the behalf of the team. At the Grand Prix, Eggman provided Team Sonic (excluding Sticks) with go-karts and allowed Team Sonic to take the lead when the race started while his Bio-scanning Who-za-ma-whats-its on their go-karts copied their bio-data in secret. While getting the data, Eggman incapacitated the racers with disguised traps and robots until only Sonic was left, whom Eggman dropped into a ravine on a rigged bridge while he headed for the finish line. However, Sonic soon returned, and despite launching all his traps, Eggman could not keep him from taking the lead. Eggman thus engaged his Spider-Kart and pursued Sonic, where he kept him from crossing the finish line. However, Tails, Knuckles and Amy then attacked him in Tails' Plane, distracting him enough for Sonic to win the race. Having lost because he broke his own rules, Eggman was surprise-attacked by Sticks and then Team Sonic, who destroyed his Spider-Kart, leaving him to vengefully flee on his mangled vehicle.

Personality
Dr. Eggman is a short-tempered, egomaniacal, raucous and pompous evil mastermind genius. He has all the qualities of a classic villain: he looks, talks, and dresses like a bad guy and possesses the psychotic sense of self-entitlement that urges him to 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 so incredibly arrogant that he denies his past failures and even finds his terrible actions justified. 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 destroying homes, getting into otherwise awkward situations or teaming up with 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 he takes great pride in his mustache, which he grooms professionally and would give up his chance at power to preserve. While sometime showing the tendencies of a neat-freak, Eggman actually has poor personal hygiene.

Despite his intelligence, 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. When in situations over his head though, he is willing to abandon this façade and beg for help. Excessively self-deluded, he thinks others secretly admire him and only mock him out of jealously. 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, while things might not always work out for Eggman initially, he is always working behind the scenes, either with hidden agendas or manipulation of others, 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. 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, he also has fairly good reflexes as he was able to dodge laser fire from five separate 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. With it, Eggman is able to take control of virtually anything electronic around him as long as it is not manually controlled. However, he is not always able to use it correctly, like when Obliterator Bot went rampant despite his attempts to use this device. The controller also has offensive functionalities, like firing beams that can encapsulate victims in force fields and shooting lasers that can incinerate the targets. Additionally, the wrist controller beeps and flashes blue to remind Eggman of a scheduled task, much like a watch.

Sonic the Hedgehog
Sonic the Hedgehog is Dr. Eggman's arch enemy who he has fought for years, and many of his schemes centers around ensuring his destruction. However, their relationship tends to be rather complex. When fighting, Eggman is very hostile towards Sonic while showing a sense of superiority, but he gets furious at Sonic's taunts. Outside their fights however, they are much less hostile, allowing each other to be their presence without them going at each other's throats. In times whenever he finds himself in situations over his head, Eggman is also not above asking (or begging) for Sonic's help.

Regardless of his dislike of Sonic, Eggman has a certain fondness of him and has an interest in sharing his friendship, even calling themselves "bros" while having a camping experience with him. In Eggman's own opinion, just because they are sworn enemies, it does not mean they cannot be friends. Also, when dealing with a common threat or problem, they are willing to put aside their differences and work together, even sometimes showing a sense of good-spirited comradery and well-oiled teamwork, though 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 or drive to be a villain and will sink into a slump of self-pitty. For better or worse, their ever-ending conflict is what drives them and keeps their lives balanced.

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 covers it up by telling them how little they mean to him.

Most of the time, Eggman views Orbot and Cubot as unintelligent and hopelessly incompetent, and give them little but terrible treatment in return for the often grueling services 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. 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.
