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..."

- Doctor 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 on the lower portion of the torso (the stomach), Dr. Eggman's torso is more round at the top, like an upside-down egg, 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.

Compared to his main series counterpart, the doctor's outfit has been dramatically redesigned, having been given a more militaristic appearance. He still wears a red jacket with yellow cuffs, blue pince-nez glasses, white gloves and a set of grey goggles with green lenses on top of his head. However, his goggles are slightly thicker and smaller and has flappable lenses, and his jacket has a front flap that is attached to one of the jacket's buttons and two flap hanging from the back. He also carries a device on his right wrist and wears grey pants and a pair of black boots with high rims.

Sonic Boom: Rise of Lyric
Eggman is set to appear in Sonic Boom: Rise of Lyric as a secondary antagonist, since Lyric the Last Ancient is the principal antagonist of the game, and the two of them will have an uneasy partnership.

TV series
As 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 Obliteratorbot, 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 Obliteratorbot 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 Obliteratorbot, 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 a robot 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 becoming a nominee for the Awardy Award with Stufferbot, Eggman attended the Awardies, but when he lost the award to Leroy the Turtle, Eggman attacked with Stufferbot and his minions in vengeance. While Eggman incapacitated most of Team Sonic at the gala, Sticks freed her friends, who made a counterattack and 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 fast meal at Meh Burgers 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 liked 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 a batch of evil cookies, infused with his own DNA, to feed to Sonic and turn him into his clone, 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 robots, which at the moment hosted the Gogobas. After his robots were destroyed, 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 constant guilt trips.

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 robots, 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 whom he just met, 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 Egg Mobile 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.

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. Accepting Knuckles' offer, Eggman quickly patched up and upgraded the Big Boy, and engaged Team Sonic again, where he called in Knuckles who helped him trap Sonic and his allies. With the heroes loaded onboard the Big Boy, Eggman headed towards the local village to attack it, but was betrayed by Knuckles who had faked allying with him. After failing to protect himself with his lackeys, Eggman retreated once more in the Big Boy as Knuckles tore it appear, 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.

Personality
Dr. Eggman is a short-tempered, egomaniacal, raucous and pompous evil 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. As 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.

Despite his intelligence, Eggman is deranged, immature and stressed in behavior with a lot of comical undertones. While his pride and arrogance are his core parts, they are also his greatest weakness, as they make him far too overconfident and lead to his downfall. He is also laidback, self-deluded and somewhat of a doofus, not using necessary parts for his robots, geeking out with Tails in a battle, and sneaking in on his enemies to plant a robot rather than using the opportunity to attack them in their sleep. Likewise, when in situations way over his head, he will often degrade himself by begging for help. Because of his flaws, no one really considers him a true "bad guy," indicating that he is not as evil as he makes himself out to be. However, while things might not always work out for Eggman 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. His remarkable skills as an engineer and programmer are best evidenced by the armies of robots, mechs and doomsday 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.

After eating a 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 Obliteratorbot went rampant despite his attempts to use this device. The controller also has offensive functionalities, like firing beams that can encapsulate victims in unbreakable force fields and shooting lasers that can incinerate their 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 nearby without them going at each other's throats, though on Eggman's part he often uses this as a mean to further his plans. Also, whenever he finds himself in situations over his head, Eggman is 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 being his friend.

Orbot and Cubot
Orbot and Cubot are the closest things Dr. Eggman has to friends and even considers them family. Regardless, he admits he does not really care for them and gives them little but terrible treatment in return for their services, such as dismissing their company, berating them on a daily basis, having them set up their own party 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.
