Doctor Eggman's Lair

Dr. Eggman's Lair is a location that appears in the Sonic Boom series. It is the ultra high-tech stronghold and residence of Dr. Eggman and his lackeys Orbot and Cubot, located just outside the coast of Bygone Island. From here, Eggman hatches his evil schemes to conquer the world and eliminate Team Sonic. The lair itself is a registered trademark of Eggman Industries.

Appearance and architecture
Dr. Eggman's lair is located on a small rock island barren with life and with veins of lava running across it. The central location is a white futuristic fortress-tower on the top of the island's tallest peak with an antenna in the shape of Eggman's mustache, an outer shell surrounding it, and the Eggman Industries logo on the side.

The layout of Eggman's fortress extends into the foundation of the island. At the foot of the fortress's peak is the main entrance to the lair which is surrounded by several pillar-shaped turrets, and beneath the ground is the lair's sewer system which is big enough for the members of Team Sonic to pass through. On the island also lies a small green garden with topiaries and a gazebo which Eggman retreats to when he needs to calm his nerves.

Defenses and functionalities
The lair possesses several defenses against intruders. The walls of the fortress' outer shell is covered by laser turrets and grids for inward defenses and the front entrance is protected by stationary laser turrets. Additionally, the fortress' interior rooms have camera-like laser turrets on the walls and electrified net traps to ensnare and paralyze intruders. Badniks also patrol the island and guard the inside of the fortress. However, there is said to be a hole in the defenses below an unspecified location.

Eggman's lair acts as a remote energy source for its robots. Through the lair's own energy reserves, Eggman can relay power remotely to his robot hordes to empower them. It also holds remote kill switches for Orbot and Cubot.

Interior
In addition to being the central for Dr. Eggman's planning of his evil plots and his robot hordes, the lair also serves as Eggman's residence and living quarters. It includes the following areas:
 * Dr. Eggman's office: A large room shaped like the Eggman Industries logo which contain a lone chair and desk with touchpad controls. Feature high-tech computers screen on the walls which are controlled from the desk and disco-lighting with sound systems.
 * Laboratory: A long working quarter which shares the same space as the living room. Here, Eggman tinkers with his robots and other experiments. Features a pop-up screen for outside surveillance.
 * Shoe closet: An enclosed room with several selves that are filled with Dr. Eggman's boots.
 * Living room: A casual living room which shares the same room as the laboratory. Features furniture like a sofa, a coffee table, a tall lamp and a book case embedded in the wall.
 * Bedroom: A lone room that serves as Dr. Eggman's sleeping quarters. It is identical in design to the living room/laboratory, but features instead a bed and a nightstand in place of the other furniture.
 * Rollercoaster room: A bright room containing a rollercoaster, whose entrance is colored a festive red and yellow. Supposedly, the rollercoaster inside is so intense that it can tear Orbot and Cubot apart.
 * Bathroom
 * Missile silo: A missile silo contained inside the fortress for deploying missiles made by Eggman Missile Industries.
 * Movie theater: A small theater with a few rows of seats for showcasing films.
 * Thinkcubator: A room where Dr. Eggman comes up with his evil scheme. Its name is a pun on how the doctor "hatchets" his plans inside it.
 * Rumpus room
 * Hangar: A hangar large enough to hold the Big Boy.

TV series
Long ago, Eggman's lair hosted the doctor's rejected Cubot prototypes who were scheduled to be recycled. Using secrets tunnels in the lair though, the prototypes escaped to the Valley of the Cubots.

At his lair, Eggman heard that Sonic sought a new sidekick. While Orbot and Cubot voiced their opinions, Eggman had the idea to apply to destroy both Sonic and Tails, but his plan failed. In a later scheme to weaken Sonic and Tails, Eggman convinced them to let him stay with them by lying that he had to repair his lair. However, when Eggman's Obliterator Bot malfunctioned and started attacking the doctor's lair instead of Team Sonic, Eggman teamed up with them to get through his lair's defenses and reach Oblteratorbot's kill switches. However, they were too late, and the lair was reduced to a ruin which Sonic forced Eggman to stay at.

As Eggman spied on Team Sonic fro his lair, he learned Tails' UT robot was creating tension in the group by revealing their private thoughts. Eggman thus secretly replaced UT with a duplicate and made Team Sonic tear themselves apart from his lair. As Eggman took time to enjoy UT voicing his self-praise, Tails invaded the lair and gave his services to Eggman in exchange for UT's release. However, the rest of Team Sonic soon attacked the lair and freed Tails after destroying the Mega.

When Sticks sought a pet, Eggman took time in his lair's lab to build Buster to infiltrate and destroy Team Sonic, which failed. Eventually, Eggman's lair was considered to be in Modern Lair Magazine. Despite Eggman's attempts to spruce it up, the photographer's assistant deemed it too old-fashioned. Having a week to redo the lair, Eggman hired Amy for the job and earned the messenger's approval. Eggman then captured Amy in his lair to keep her as his decorator, but the rest of Team Sonic broke freed her, before trashing the lair on their way out and costing it its place in Modern Lair Magazine.

Eggman's lair soon after hosted Eggman's intern, Dave who took care of its menial tasks. When he overheard Cubot's dislike of him, Dave dismantled him and hid him until Orbot found him. As Eggman told Dave to wait for the big projects, Dave sealed himself in the lair's lab and activated Eggman's doomsday device to prove himself a villain. Just as Eggman built another doomsday device to compete with Dave's, Sonic and Tails made the villains calibrate their devices into negating each other. However, they instead created a black hole over the lair which Sonic closed.

Having the idea of turning Sonic evil, Eggman created Evil Cookies in his lair to feed Sonic. Though Knuckles, Amy, Sticks and Tails ate them instead, the evil heroes came to the lair to plot Sonic's end, where Eggman taught them villainy until Sonic arrived. When they had Sonic cornered though, Tails, Knuckles, Amy and Sticks fought over the honor for capturing him. To stand a chance, Sonic fed Eggman an Evil Cookie with his DNA, and together, the unlikely duo got everyone back to normal. The good Eggman now thought they would work together, but Team Sonic was not keen on that and restored Eggman. Not long after, Eggman was tricked by Sonic into taking the Gogobas to his lair where they constantly bothered Eggman with their guilt tripping until they left.

To boost Orbot and Cubot's moral, Eggman had them set up a party in the lair for themselves and then erased their memories to make it a surprise. However, while Eggman went for a snack, Orbot and Cubot left to look for him. When they returned to the lair, Eggman gave them their party and heard that they thought he was dead. Eggman then erased Orbot and Cubot's memory as a demonstration, but also any clue as to where his Eggmobile was (which Orbot and Cubot had lost). While at his lair another time, Sonic and Tails warned him that Cowbot, a robot he had just sent after them, was coming to kill him. Plotting to have the duo upgrade his lair for him, Eggman made them stay and upgrade the lair's defenses to be ready for Cowbot. As they waited for Cowbot to arrive, Sonic, Tails and Eggman spend the day hanging out which ended with roasting marshmallows. When Cowbot arrived, the defenses got gunked up with marshmallows, so they resorted to gunking up Cowbot's systems instead. Eggman then revealed his true agenda, which Sonic put a stop to by gunking up the systems with marshmallows.

Following another defeat by Team Sonic, Eggman returned to his lair to watch television, where his remote was constantly destroyed by Tails' Unbolterizer. During a laser tag exercise in his lab later on, Eggman discovered the luck balance of the universe had shifted in his favor, which inspired him to mobilize an invasion of Bygone Island, sure he was now untouchable. Once again though, he was beaten. Later, when Sonic and Eggman switched minds due to a meteor, Orbot and Cubot brought Sonic back to the lair, believing he was Eggman. When Sonic could not convince Orbot and Cubot of who he was, he left the lair to find his team, only to return when they drove him away. There, he assembled Eggman's army to fight Eggman in his body. Once Sonic and Eggman were back to normal, Eggman returned to his lair in defeat.

When Dr. Eggman lost his confidence, he brought Soar the Eagle to his lair to take his life coaching seminar. Soar soon restored Eggman's confidence, but since Eggman fired him prematurely, he became unable to make decisions and stayed in his lair, having lost all motivation. Team Sonic, excluding Sonic, came to the lair to re-motivate Eggman since Sonic's boredom was driving them crazy, but their attempt to make them fight failed. However, Sonic and Eggman were able to restart their conflict once more on their own. As he was playing a video game in his lair, Eggman got a pop-up stating Tails had joined the Lightning Bolt Society. Finding this group already annoying as it was, Eggman left his lair to foil any involvement Sonic would have with them.

Having gained success with his Eggman's Tomato Sauce, Eggman hosted the Comedy Chimp Show at his lair where he revealed his plan to take control of Bygone Island's appliances with his robot sauce cans. As Eggman started his plan, Team Sonic came to stop him, but were outmatched by the numerous robots. Fortunately, Tails swooped by in his plane and took Eggman's control which he used to disable the robots. Having also accidentally ruined his plan by revealing it on television, Eggman was left with thousands of unsold tomato sauce cans in his lair. When Eggman later convinced Sonic that his running was creating a horrible noise, Eggman took him to his lair where he ran some "test" and gave Sonic new shoes with Power-absorbant Insoles. While Eggman claimed they would mute the sound, they would actually power his Giant Robot whenever Sonic ran, but his scheme was foiled by Sonic himself. Upon having a tolerable morning in his lair, Eggman departed in his Egg Tank to battle Team Sonic. However, Eggman accidently created a time loop which repeated the day endlessly, causing Eggman to repeatedly wake up in his lair. When Eggman realized the loop kept him from defeating Sonic, he began working in his lair to solve the problem, bringing Team Sonic over (after several attempts) for help. With their help, Eggman sealed the time loop with a special container.

While in his lair, Eggman discovered a Granifier Giganticus and went with Orbot and Cubot to enslave it. When they failed, Eggman returned to his meditation garden for relaxation, only for Team Sonic to arrive with the monster who fell asleep in his garden to horrible music provided by the heroes, which Eggman had to accept to avoid further collateral damage. Eggman later met Nominatus on the internet and would spent time chatting with him in his lair, something which made Orbot and Cubot leave for feeling unappreciated. Eggman soon entrusted his lair's schematics to Nominatus, unaware he was using them to take over the lair to destroy the world. Orbot and Cubot returned to warn Eggman of Nominatus, but were too late. His agenda revealed, Nominatus drove the trio out of the lair using its own defenses, but was later purged from its systems by Orbot and Cubot.

While Sonic and Amy hanged out, the two visited Eggman's lair where they blew up its antenna. The lair was further damaged later on when one of Eggman's missiles, launched by Amy and Sticks, hit it. As Eggman spied on Team Sonic from his lair, only for the heroes to play a prank on him by misleading Fly Bot. Eggman blamed this humiliation on machines, and deserted his lair to start over without tech. Seizing this opportunity, the Lightning Bolt Society took the lair as their new base. While lounging about, they haphazardly pressed buttons that launched weapons, deployed robots, and shut down Orbot and Cubot. Team Sonic and Eggman thus went to the lair and made the Lightning Bolts leave after misleading them over the surveillance, though Eggman had to spent weeks reprogramming his lair. When the garbage man later went on vacation, the trash consisting of failed inventions started to pile up at the lair, prompting Eggman to head for city hall to complain.

Eggman's lair later hosted the movie premiere of his mind-enslaving movie which he had convinced the villagers to come see. In the lair's movie theater however, Eggman found everyone laughing at his movie and discovered he forgot to add the mind-enslaver device to the movie, so he had everyone leave for him to watch his movie alone. Later observing from the lair that Sonic had retired and Team Sonic was out of town, Orbot and Cubot proposed an attack, but Eggman insisted that as he would only coax Sonic out of retirement that way and so stayed in his lair until Sonic was in a vulnerable position, only for his attempt at a sneak attack to fail. Another time, Eggman's lair was infiltrated by an alternate dimension Knuckles whom Eggman captured. Soon after, Team Sonic invaded the lair to save this Knuckles. Understanding that their dimension was at risk of imploding from hosting two Knuckles, Eggman released this Knuckles and provided the tech to sent him home.

Sonic and Tails later came to the lair to accuse Eggman of thievery, though he proved innocent. Suspecting the Cubot prototypes was behind it, who had robbed the lair too, Eggman sent Orbot and Cubot after them. When only Orbot returned as Cubot was staying with his prototypes, Eggman probed Orbot for their location so he could destroy them before Cubot told any lair secrets. Though the attack failed, Eggman got Cubot back to the lair. One other time, when Dave the Intern imprisoned Eggman, Dave came to the lair and stole Octopus Bot while Orbot and Cubot were oblivious to Eggman's disappearance. On New Year's Eve, Eggman tried celebrating in his lair with Orbot and Cubot, but was too upset over not having fulfilled his past resolution of beating Sonic just once this year. As Orbot presented his slow-cooked roast though, Eggman had the idea of turning their slow cooker's power source into a device for slowing down time so he would have enough time to beat Sonic, which he deployed in the Village Center.

Waiting at his lair for a package, Eggman missed it while he took a shower. To get it from the post office, he thus had to search his lair's trash for a note the mail man left behind. Comedy Chimp later came to the lair where he made a deal with Eggman: in exchange for Eggman sponsoring an attack that would remove Knuckles as the host of the Comedy Chimp Show, Eggman Industries could sponsor the show. Later on, Eggman staged the thievery of his Particle Accelerator in his lair to frame Sonic. While visitors were allowed into the lair to see the crime scene, Eggman got both the police and Sonic over and accused the latter with fake clues. Sonic however, fled to clear his name.

When the lair got solar panels to lower its power bills, Eggman accumulated tons of robot energy. However, as the Archipelago Homeowners Association threatened to evict him due to his lair housing robots, Eggman hid his robots while he had the association over for dinner to prove he had no robots. However, the lair's panels absorbed power from a thunderstorm, making its robots go nut from power overload and blow Eggman's ruse. With Team Sonic arriving to protect the association, Eggman established his robots were art and thus kept his lair. After Eggman and Amy became "Fuzzy Puppy buddies," the unlikely duo met up several times in Eggman's lair to discuss and play with Fuzzy Puppies. Eggman would also retreat to his lair to sulk when Team Sonic got an award, but was encouraged by Orbot and Cubot to go out and get his own.

Eventually, Eggman invited all the local villains and rogues to his lair to form a league of villains to take down Team Sonic. After some leadership arguments and team exercises, Team Eggman decided to let Eggman lead them so they could prove themselves after Shadow left the group dissing them, and spent some time preparing at the lair before going after Team Sonic.

The Big Boom
After being defeated in his Big Boy, Dr. Eggman retreated to his lair. The next day, he was unexpectedly approached by Knuckles at the lair who proposed an alliance. However, this turned out to be a plot by Knuckles-albeit ill-planned-to help his friends defeat the Big Boy in their next engagement. Eggman promptly returned to his lair to have Orbot and Cubot repair the Big Boy. However, Cubot and Orbot got distracted by the piko hammer inside the Big Boy and ended up inflicting damage. As a result, when the Big Boy left the lair, it fell apart as the piko hammer was flung back to Bygone Island. The Big Boy was soon repaired again, but got destroyed once more by Team Sonic, so Eggman returned home, where he revealed to his minions that he had another creation ready for Team Sonic.

Boom Shaka-laka and Worlds Unite
Back in his lair after failing to sell a bridge to the villagers, Eggman surmised he had to earn their trust to use them. When he could not by showing goodwill, Eggman set up the Eggtoberfest at his lair so he subtly buy the villagers' trust. Having gotten Team Sonic to operate the rides, Eggman discovered from inside his lair that the villagers were not falling for his scam and sicced his robots on them. However, Team Sonic beat Eggman's army, leaving the Eggtoberfest a smoking ruin around Eggman's lair.

When meeting the Maverick Hunters, who got stranded in their dimension, Team Sticks took them to Eggman's lair to find a dimension-travel device. Having "persuaded" Orbot and Cubot, the duo made them a Genesis Portal with one of Eggman's machines which the group passed through. These events in the lair would be erased when Xander Payne rewrote history.

As Eggman dwelled in his lair, he decided to buy a gorilla for a new henchman. Several weeks later, Kyle the Gorilla arrived at the lair in a crate and subsequently drove Eggman out when he went flipped out and trashed the lair over his rough transfer. However, Kyle left when Sonic offered him a new home. Back home, Eggman would spy on Team Sonic from his lair in search of his lost earpiece, only to find it when he stepped on it. No sooner, the second gorilla Eggman ordered came to the lair, who beat up Eggman as well.
