A brilliant scientist with an IQ of 300, Eggman is driven by a desire to conquer the world and establish his own empire, the [[Eggman Empire]]. Central to his vision is [[Eggmanland]], a city he seeks to build as the backbone of his regime. His ambitions are fueled by his love of machines and extreme egomania.

Eggman continually devises plots to achieve world domination, which range from using [[Animals]] to power his robots—known as [[Badnik]]s—to constructing massive war machines, harnessing ancient powers, and manipulating spacetime itself. Despite his genius, his plans are always foiled by [[Sonic the Hedgehog]] and his friends. Nevertheless, Eggman remains undeterred, always managing to escape capture and continuing his quest for conquest. His narcissism and immature behavior often lead to his downfall, but his unrelenting pursuit of power makes him one of the most dangerous threats in the universe.

==Concept and creation==
[[File:S1concept-eggman.jpg|thumb|left|200px|alt=Illustration by Naoto Ohshima of a mustachioed man in pajamas that evolved into Doctor Eggman.|Initial concept artwork for the character that would evolve into Dr. Eggman.]]
In April 1990, [[Sega]] sought a new mascot to rival [[Nintendo]]'s [[Mario]].<ref name="lame title">{{cite web|url=http://www.1up.com/features/essential-50-sonic|title=Sonic Boom|last=Kennedy|first=Sam|publisher=[[Wikipedia:1UP.com|1UP.com]]|archiveurl=https://web.archive.org/web/20110604011401/http://www.1up.com/features/essential-50-sonic|archivedate=June 4, 2011|accessdate=September 24, 2014}}</ref> Several character designs were submitted by its AM8 research and development department, which later evolved into [[Sonic Team]]. Among these was a sketch of a mustachioed man in pajamas, drawn by [[Naoto Ohshima]].<ref name="Realcreator"/> This concept was set aside in favor of [[Sonic the Hedgehog]], also designed by Ohshima.<ref>{{Cite web|date=March 21, 2018|title=Sonic the Hedgehog's origin story, according to the devs who made him|url=https://www.gamedeveloper.com/design/-i-sonic-the-hedgehog-i-s-origin-story-according-to-the-devs-who-made-him|archiveurl=https://web.archive.org/web/20220201110459/https://www.gamedeveloper.com/design/-i-sonic-the-hedgehog-i-s-origin-story-according-to-the-devs-who-made-him|archivedate=February 1, 2022|accessdate=February 22, 2022|publisher=[[Wikipedia:Game Developer (website)|Game Developer]]}}</ref>

===Naming and Western interpretations===
[[File:Robotnik 4.png|thumb|left|180px|alt=North American artwork of "Doctor Robotnik" from the early 1990s. His glasses are noticeably replaced by completely black eyes and his gloves are missing.|1990s Western stock artwork of "Dr. Robotnik".]]
When ''Sonic the Hedgehog'' first released, Sega of America named the character "Dr. Ivo Robotnik". This name was made by Sega game counselor and designer [[Dean Sitton]]: "Ivo" was picked because of its phonetic similarity with the word ''evil'' and its reversal to ''ovi'', Latin for ''eggs'', while "Robotnik" was chosen for its Slavic roots related to work, fitting with the game's industrial themes. Other names considered were "Mr. Badwrench" and "Dr. X".<ref name="SittonRetro">{{Cite web |date=January 16, 2009 |title=DeanSatan enters the fray! |url=https://forums.sonicretro.org/index.php?threads/deansatan-enters-the-fray.13659 |work=Sonic Retro |accessdate=May 13, 2022}}</ref> This name change was done without [[Sonic Team]]'s consent.<ref name="EggmanRobotnik">{{Cite web |author=Casey |date=June 4, 2016 |title=Sega Explains How Dr. Robotnik Came To Be Called Eggman |url=https://www.siliconera.com/2016/06/24/sega-explains-dr-robotnik-came-called-eggman/ |work=Siliconera |archiveurl=http://web.archive.org/web/20160625131949/https://www.siliconera.com/2016/06/24/sega-explains-dr-robotnik-came-called-eggman/ |archivedate=June 5, 2016 |accessdate=May 13, 2022 |quote='''[[Takashi Iizuka]]''': When the game was originally developed in Japan, they called the character Eggman. That was the name of the character, but when the game got localized and ported into the Sonic the Hedgehog that we know in the West, they decided to, without confirming with the development team, change his name to Ivo Robotnik or just Robotnik. That's kind of when everyone first learned about the character. Of course, this was without consulting the people who made the game. They just kind of went off and did it. It became super popular and everyone in the West kind of learned about the character as Robotnik. [...] We [Sega of Japan] really didn't want to have anyone in the universe with two names. To us, he's Eggman, but in the rest of the world he's called Robotnik. We wanted to unify that into one name moving forward. This is something I actually did in the Sonic Adventure series. I made it so that we understand the character's name is Robotnik, but his nickname is Eggman, and as far as everyone is concerned in the world now, we're just going to call him Eggman as his official name.}}</ref>

At Sega of Japan's permission, Sega of America developed their canon in their [[Sonic Bible]] document, a reference document used by screenwriters, they established that Robotnik was originally a kind scientist named "Dr. Ovi Kintobor", who turned into his current self following a lab accident. The character was depicted with inconsistent designs in the West, often with variations from the Japanese design, such as omitting his glasses and gloves, and exposing completely black eyes. In some occasions, his designs from the [[DiC Entertainment]] cartoons were used instead, such as in ''[[Dr. Robotnik's Mean Bean Machine]]''. These differences were slowly abandoned over time, and the Japanese canon became the standard.

All the while, the Japanese material referred to the character as "Eggman", as the Western material called him "Robotnik".<ref>{{Cite web|url=https://play.google.com/store/apps/details?id=com.sega.sonic1px&hl=en_US&gl=US|title=Sonic the Hedgehog™ Classic|publisher=Google Play Games|date=January 21, 2017|accessdate=February 9, 2022|quote=While 'Eggman' is Dr. Robotnik's nickname in the West, he has always been known as 'Eggman' in Japan.}}</ref> When the Sonic series was transitioning into 3D, ''[[Sonic Adventure]]'' became the first time both names were officially used, with subsequent releases primarily referring to him as "Eggman".

While he is oftentimes called "Eggman" in Japanese sources, the use of "Robotnik" has only been on rare occasions like guides of ''[[Sonic Adventure]]'' and ''[[Sonic Jam]]'' in said region.{{Citation needed}}

Eggman is an obese, tall [[human]] with a small, bald head. He has a distinct pinkish nose and a bushy, mahogany-colored<ref name="Scholastic" /> mustache. His eyes, which are very rarely seen, are colored blue.<ref name="Scholastic">{{Cite book |author=[[Devra Newberger Speregen]] |title=[[Sonic: The Ultimate Character Guide]] |publisher=[[Scholastic]] |date=2016 |page=23 |isbn=978-1338033243 }}</ref><ref>{{Cite game|dev1=[[Sonic Team]]|dev2=[[Blindlight]]|date=November 4, 2006|fullgame=[[Sonic the Hedgehog (2006)|Sonic the Hedgehog]]|system=PlayStation 3|publisher=[[Sega]]|cutscene=Eggman sends Sonic to the future (Sonic Episode)}}</ref><ref group="note">In ''[[Sonic Battle]]'' and ''[[Sonic Mania Adventures]]'', Eggman has black eyes instead of blue ones.</ref>

Eggman's Classic design features a totally spherical torso with thin but proportionate arms and legs. He wears a red top with a short yellow cape, attached to his shoulders by a triangular collar, black pants with attached boots and a pair of large silver buttons on the front. This outfit is complemented by white gloves and blue (sometimes black or silver) pince-nez glasses that completely hide his eyes. His mustache is neatly groomed, with only three tufts sticking out at each end. Unlike in the modern age, he was shorter in than he is now.

In his Modern redesign, Eggman has become somewhat taller and burlier, with a torso now roughly shaped like an egg, hence his nickname.<ref name="SA2Prima">{{Cite book|author=Prima Development|title=Sonic Adventure 2: Prima's Official Strategy Guide|publisher=Prima Games|page=3|chapter=The Beginning|date=June 20, 2001|isbn=978-0761536147}}</ref><ref name="HeroesUSManual">''[[Sonic Heroes]]'' ([[PlayStation 2]]) United States instruction booklet, pg. 12.</ref> His arms and legs have become long and almost disproportionately thin, while his mustache has become more unkempt.

He now dons a red coat adorned with four golden buttons on each side of the chest, each accompanied by white straps running to additional identical buttons on the back. The coat features silver linings down the back, arms, and front, yellow cuffs, and two extensions on the front with large silver buttons. Additionally, Eggman wears black pants with matching boots, which have circular plates on both sides of the ankles and three square ones extending up the shin.

At the start of the "[[Death Egg saga]]", Eggman invaded [[South Island]], kidnapping its [[Animals]] to use as fuel sources for his new robot army, the [[Badnik]]s. His goal was to find the six [[Chaos Emerald]]s said to rest there to build weapons of mass destruction. However, Sonic secured the Emeralds first and expelled the doctor from the island.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = June 23, 1991 |game = Sonic the Hedgehog (1991){{!}}Sonic the Hedgehog |system = Sega Mega Drive |pub = [[Sega]]}}</ref><ref name="Sonic1JPManual" /> Eggman later chained [[Little Planet]] during its annual appearance over [[Never Lake]], coveting its [[Time Stone]]s to control time.

Eggman would go on to hatch more schemes to take over the world, like building a [[Death Egg mk.II]] around Little Planet<ref>{{Cite game |dev1 = [[Sonic Team]] |dev2 = [[Dimps]] |date = May 15, 2012 |game = Sonic the Hedgehog 4: Episode II |system = PC |pub = [[Sega]]}}</ref> and discovering a gem known as the [[Phantom Ruby]].<ref>{{Cite game |dev1 = [[Christian Whitehead]] |dev2 = [[Headcannon]] |dev3 = Pagoda West Games |date = August 15, 2017 |game = Sonic Mania |system = Nintendo Switch |pub = [[Sega]]}}</ref> In one incident, he even met an older version of himself to defeat Sonic.<ref name="Generations">{{Cite game |dev1 = [[Sonic Team]] |date = November 1, 2011 |game = Sonic Generations |system = PC |pub = [[Sega]]}}</ref> Each time, however, Eggman would fail.

Eggman eventually unleashed a deity of destruction known as [[Chaos]]. His plan was to feed him the seven Chaos Emeralds and use him to destroy [[Station Square]] to build [[Eggmanland]] on its ruins. Central to his scheme were also the [[Egg Carrier]] airship and the [[E-100 Series]] Badnik robots.<ref name="AdventureTokyoInternational">{{Cite book |title=Sonic Adventure Tokyo International Forum Unveiling Booklet |date=August 22, 1998 |chapter=All Star Cast |page=9}}</ref> Although he came close to achieving his goal, giving Chaos six of the Emeralds, Sonic and his friends ultimately destroyed the Egg Carrier and seemingly killed Chaos. Devastated, Eggman attempted a suicide attack on Station Square that was foiled by Tails. Not long after, he rediscovered Chaos but was knocked out by it as it took the final Emerald, rampaging on Station Square on his own. The doctor tried to stop him with the [[Egg Carrier 2]], but was effortlessly defeated. He survived, only turning up again just in time to witness Sonic's victory against Chaos before withdrawing.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = September 9, 1999 |game = Sonic Adventure |system = Dreamcast |pub = [[Sega]]}}</ref>

Eggman later discovered his grandfather's diary, which detailed a top-secret project called "[[Project Shadow]]". Intrigued by this lost research, he infiltrated the military facility on [[Prison Island]] and released [[Shadow the Hedgehog]], the "Ultimate Life Form" created by Gerald. Together with Shadow and [[Rouge the Bat]], Eggman sought to gather the Chaos Emeralds to power the [[Eclipse Cannon]], a weapon aboard the [[Space Colony ARK]] capable of destroying planets. His ultimate goal was to use the ARK to blackmail the world into submission. Despite initial successes, including activating the Eclipse Cannon, Sonic and his friends thwarted Eggman's plans. He was forced to team up with his adversaries after activating a doomsday program that would cause the ARK to crash-land into Earth, culminating in Shadow's apparent sacrifice.<ref>{{Cite game |dev1 = [[Sonic Team USA]] |date = June 23, 2001 |game = Sonic Adventure 2 |system = Dreamcast |pub = [[Sega]]}}</ref>

Later, Eggman learned of the [[Wisp]]s, aliens containing [[Hyper-go-on]] energy, which he planned to use for a mind control cannon to conquer the universe.

Eggman later re-discovered the [[Phantom Ruby]] and used it to empower [[Infinite]], his new right-hand man. With this power, Eggman defeated Sonic and imprisoned him on a rebuilt Death Egg, allowing him to conquer the world. However, he was opposed by Sonic's friends, who formed the [[Resistance]], triggering the [[War to Take Back the Planet]]. Six months later, the Resistance freed Sonic and was joined by Classic Sonic. Despite Eggman's efforts to foil them, the heroes liberated most of the planet and defeated Infinite. Eggman then used the Phantom Ruby and the [[Death Egg Robot (Sonic Forces)|Death Egg Robot]] in a final effort to win the war, but was ultimately defeated by Sonic and his friends.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = November 7, 2017 |game = Sonic Forces |system = Nintendo Switch |pub = [[Sega]]}}</ref>

Most recently, Eggman sought to exploit the advanced technology created by the alien [[Ancients]] on the [[Starfall Islands]]. He created an AI named [[Sage]] for protection but became trapped in [[Cyber Space]]. Over time, he inadvertently bonded with Sage, whose abilities far exceeded his expectations. Sonic eventually destroyed the islands' [[Titan (Sonic Frontiers)|Titans]], freeing his friends and Eggman, but also releasing [[The End]], a world-threatening entity. Sonic defeated The End with Sage's help, culminating in Sage's sacrifice. Devastated, Eggman later recovered Sage's data and partially restored her much to her joy.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = November 8, 2022 |game = Sonic Frontiers |system = PlayStation 4 |pub = [[Sega]]}}</ref>

Owing to his delusions of grandiosity, Eggman refuses to let others cause destruction outside ''his'' direction.

In the IDW Comics, Dr. Eggman is an evil and megalomaniacal genius who is constantly planning to take over [[Earth]] and those beyond his. Showing contempt for how "filthy" and "irregular" the world is, he views himself as obligated to perfect it by ridding it of what he deems as imperfections, including hunger, disease and, above all, free will.<ref name="StH16">[[IDW Sonic the Hedgehog Issue 16|''Sonic the Hedgehog'' #16]], "Infection"</ref> Arrogant, raucous and explosive, he believes that he is bringing peace and unity to Earth under his brilliant leadership, but has no qualms about destroying the Earth and all life on it before moving on to another world if needed.<ref name="StH12">[[IDW Sonic the Hedgehog Issue 12|''Sonic the Hedgehog'' #12]], "The Cost of the Battle for Angel Island"</ref><ref name="StH23">[[IDW Sonic the Hedgehog Issue 23|''Sonic the Hedgehog'' #23]], "The Last Minute, Part 3"</ref> He also does not accept the world as it is as a whole. Instead, he wants to transform it to his liking and set up terrifying amusement parks like [[Eggman Land (IDW)|Eggman Land]]. His reason for doing so is that he simply likes amusement parks and does not care about their effectiveness; all he wants is to control precisely what his enemies experience in their last moments. Eggman likewise prefers to show up and claim responsibility whenever he is carrying out his villainous deeds and make himself known to his enemies after he comes back from a defeat;<ref name="StH1">[[IDW Sonic the Hedgehog Issue 1|''Sonic the Hedgehog'' #1]], "Fallout, Part 1"</ref><ref name="StH13">[[IDW Sonic the Hedgehog Issue 13|''Sonic the Hedgehog'' #13]], "Calling Card"</ref> as put by [[Sonic the Hedgehog/IDW Publishing|Sonic]], subtlety is not Eggman's forte.<ref name="StH2">[[IDW Sonic the Hedgehog Issue 2|''Sonic the Hedgehog'' #2]], "Fallout, Part 2"</ref>

[[File:EggmanVRicky.jpg|thumb|225px|Dr. Eggman threatening an innocent [[Ricky (IDW)|Ricky]], from [[IDW Sonic the Hedgehog Issue 13|''Sonic the Hedgehog'' #13]].]]
Eggman has a tendency to often personalize his works by plastering his face or overall image all over his creations, like the [[Faceship]].<ref name="StH16" /> Other times, he focuses his work around a specific theme.<ref name="StH4">[[IDW Sonic the Hedgehog Issue 4|''Sonic the Hedgehog'' #4]], "Fallout, Part 4"</ref> He also uses every situation he can get to personally destroy his enemies and move closer to the realization of his ambitions, as well as evade every instance where he is supposed to take responsibility for his actions and the consequences that follows as a result of his half-baked schemes.<ref name="StH23" /> Having little to no honor either, Eggman is likewise depicted as having almost zero compassion and regard for others than himself. Cunning and deceitful, he will use and manipulate his minions and subordinates however he sees fit without a pang of remorse, not caring about ideals such as loyalty. He similarly uses them as tools that he can get rid of at any time after they either fail him or have served their purpose. Noticeably, he tricked [[Rough the Skunk|Rough]] and [[Tumble the Skunk|Tumble]] into turning themselves into [[Zombot]]s despite the skunk brothers being "perfect minion fodder" for him and that he owed them a deal for helping him back to his senses while he was an amnesiac.<ref name="StH15">[[IDW Sonic the Hedgehog Issue 15|''Sonic the Hedgehog'' #15]], "Patient Zero"</ref> He similarly seeks to enslave the whole world with fear. He is also shown to be extremely ungrateful and sadistic, as some of his first victims during the [[Metal Virus]] plague were the people of [[Windmill Village]] who took care of him while he was suffering from amnesia simply to test his virus and demonstrate "no good deed goes unpunished".<ref name="StH16" />

==Powers and abilities==
Eggman is an immense intellectual with an IQ of 300,<ref name="SC" /> which he genetically inherited from his family of brilliant scientists.<ref name="TailsTube2" /> He is easily one of the greatest inventors in the world, with virtually unparalleled scientific knowledge and robotic engineering skills.<ref name="SonicXEggman" /><ref name="SA2">''[[Sonic Adventure 2]]'' ([[Dreamcast]]) United States instruction booklet, pg. 9.</ref><ref name="StH2006">''[[Sonic the Hedgehog (2006)|Sonic the Hedgehog]]'' ([[PlayStation 3]]) United States instruction booklet, pg. 6.</ref> His intellect alone makes him a very formidable opponent.<ref name="TailsTube2" />

The Egg Mobile is seen at the center.|Eggman with various of his [[Badnik]] models and his trademark [[Egg Mobile]], from ''[[Sonic the Hedgehog 2]]''.]]
Eggman has designed a vast array of weapons, machinery, and devices, including armies of robot soldiers known as [[Badnik]]s, which range from basic [[Egg Pawn]]s to advanced [[Egg Gunner]]s, [[Interceptor]]s and [[Big Chaser]]s. He has even created some of the most powerful robots in history, such as [[Metal Sonic]]—who rivals [[Sonic the Hedgehog]] in speed and power—and the [[E-Series]], the last of which, [[E-123 Omega|Omega]], reputedly being the strongest robot ever built.<ref>[[Sonic Team]] (November 7, 2017).

Station]], which are armed with groundbreaking weaponry. He has developed powerful weapons like the [[Final Egg Blaster]] and the [[Chaos Energy Cannon]], capable of destroying star clusters, and devices to [[Mind Control Ray|control minds globally]] or harness the [[Chaos Emerald]]s' powers to manipulate time and space.<ref>[[Dimps]], [[Sonic Team]] (June 7, 2004). ''[[Sonic Advance 3]]''. [[Game Boy Advance]]. [[THQ]]. Area/level: Opening sequence.</ref> Eggman has additionally displayed knowledge in physiology of various creatures, as demonstrated by transforming the [[Time Eater]] into a cyborg and merging the [[Phantom Ruby]] with [[Infinite]]. His business acumen is also notable, having significantly profited from his robotic creations and associated facilities.<ref name="SonicXEggman" /> He also possessed cunningness, as demonstrated during the Chaos Incident where Eggman, after deducing Knuckles's mistaking Chaos Emeralds for Master Emerald shards, exploited this weakness by strongly implying that Sonic and Tails were hunting for Master Emerald shards themselves, resulting in the three having a battle that resulted in Eggman nabbing two of the Chaos Emeralds to feed to Chaos.

[[File:Eggman's unnamed robot (Sonic Unleashed).png|thumb|left|225px|alt=Screenshot of Sonic Unleashed's opening sequence, showing Doctor Eggman piloting a battle mech.|Dr. Eggman piloting one of his battle mechs, from ''[[Sonic Unleashed]]''.]]
Eggman's expertise extends to piloting his self-designed vehicles, from the [[Egg Mobile]] to various combat mechs. When he raided [[Prison Island]], he used the [[Eggwalker]] to overpower [[Guardian Units of Nations|G.U.N.]]'s combat robots, and even [[Sonic the Hedgehog|Sonic]] has struggled against Eggman in his mechs.<ref name="UnleashedOpening" /> Eggman also excels in driving and racing in racecars like his [[Egg Booster]]. His skills as a machine pilot are only rivaled by [[Miles "Tails" Prower|Tails]], who was able to beat him during two confrontations at one point. Eggman has shown effective coordination with allies in battle, controlling the [[Egg Salamander]] with [[Eggman Nega]] and the Time Eater with his past self. Although not frequently used, Eggman is a skilled [[Extreme Gear]] rider too, adept with various types of Gear, including his [[E-Rider]].

Physically, Eggman is surprisingly strong, quick, and agile for his obesity, although this was the opposite for him in the classic era (see below).<ref>[[Sega]] (November 6, 2007). ''[[Mario & Sonic at the Olympic Games]]''. [[Wii]]. [[Sega]]. "'''Dr. Eggman''' - Although the devious Dr. Eggman has great Skill-based abilities, he also is quite powerful.

His powers only grow greater in his dreams, considering that, as shown during the [[Sonic Dream Team|reverie incident]], when he takes over the [[reverie]] and/or probably with excessive amounts of nightmare fuel, he can become [[Nightmare Eggman]]. In this form, he can duplicate, teleport, fire lasers, create shockwaves, and have a mind that coexists within multiple bodies, making him a great threat as his chances off fully taking over the reverie and thus making his twisted dreams come true grow far too extreme.

In the IDW Comics, Eggman is a brilliant scientist and inventor with seemingly limitless mastery over technology. His remarkable skills as an engineer and programmer are best evidenced by the armies of robots, machines and mechs he has created for his numerous schemes. He is also an incredibly skilled pilot: able to manipulate many different kinds of his own mechs, robots and vehicles in difficult battles with [[Sonic the Hedgehog/IDW Publishing|Sonic]] and even his own mechs.<ref name="StH14">[[IDW Sonic the Hedgehog Issue 1|''Sonic the Hedgehog'' #1]], "Fallout, Part 1"</ref><ref name="StH502">[[IDW Sonic the Hedgehog Issue 50|''Sonic the Hedgehog'' #50]], "Battle for the Empire"</ref> He also has proficiency in using handguns.

According to Rouge, Eggman is quite physically capable despite the shape of his physique. Even [[Mimic]], a trained mercenary, shrunk away in fear when Eggman approached him. Notably, he has enough strength to swing someone at [[Doctor Starline|Dr. Starline]]'s size and weight around effortlessly and knock him out cold by slamming him into the ground.<ref name="StH14" /><ref name="StH502" /> He is also quite durable, having emerged from his massive destroyed mechs without suffering any injuries himself.<ref name="StH502" /> He also has sharp reflexes, being able to dodge a surprise attack from one of Starline's [[Multi-Tool Heel Spur]]s.<ref name="StH502" />
===Equipment===
Eggman has wielded a number of guns and weapons on several occasions, though he was never shown to use most of them. Early into the [[Lost Hex]] [[Sonic Lost World|incident]], he used a laser pistol that could fire shots powerful enough to tear a hole in the [[Tornado]]'s wings.<ref>[[Sonic Team]] (October 29, 2013).

Despite how simple they appear, Eggman's glasses are in fact highly advanced technological eyewear. With them, he could track the [[Chaos Emerald]]s' locations in the corners of the [[End of the World|distorted]] world after they were flung there by [[Solaris]].<ref>[[Sonic Team]], [[Blindlight]] (November 4, 2006).

Like his glasses, Eggman's jacket is equipped with several gadgets that can be activated with the press of some hidden buttons. During the [[Sonic Riders|first]] [[World Grand Prix|EX World Grand Prix]] for example, he could activate a holographic screen from his left arm.<ref>[[Sonic Team]] (February 1, 2006).

When racing with [[Extreme Gear]], Eggman is known to use gadgets such as comically large party poppers and mechanical boxing gloves to [[Attacks in the Sonic Riders series|attack]] his opponents.

During the [[Chaos]] [[Sonic Adventure|incident]], the doctor briefly used a small, unseen object that allowed him to teleport himself and other desired subjects somewhere else. However, the properties of this invention remain unconfirmed.<ref>[[Sonic Team]] (September 9, 1999). ''[[Sonic Adventure]]''. [[Dreamcast]]. [[Sega]].

In the IDW Comics, Eggman has been known to wield weapons on different occasions, including a small laser pistol that can fire large laser beams which can obliterate anything in their path. His goggles are also equipped with isolation lenses that protects him from the effects used to hypnotize people.<ref name="StH503">[[IDW Sonic the Hedgehog Issue 50|''Sonic the Hedgehog'' #50]], "Battle for the Empire"</ref>

==Weaknesses==
Despite his amazing intellect, Eggman's impatience and arrogance tend to make him act hastily and overlook crucial details when he tries to concentrate on a greater goal. Such was the case during the [[Dark Gaia]] [[Sonic Unleashed|incident]] when he awoke Dark Gaia too early in order to harvest his power for the construction of [[Eggmanland]] without even considering the repercussions of awakening Dark Gaia before he had reached full maturity.<ref name="ImmatureDarkGaia" /> His childish behavior can be considered a weak spot of his as well.<ref name="JamProfile" /> He also tends to let his guard down too easily causing Sonic to attack the weak spots in his mechs.<ref name="Scholastic" /> In the classic era, unlike now, he was a bit of a weakling and was alot more clumsy and cowardly than he is today.<ref>https://www.youtube.com/watch?v=rDYbwdEn7rs</ref><ref>https://www.youtube.com/watch?v=d6NJ-jRcPdg</ref>{{Better source needed}}

Far from being subtle, Eggman's overconfidence sometimes makes him boast a lot, making him accidentally reveal details about his plans and give hints to his enemies as to how to defeat him, all of this without him even realizing what he is saying.<ref name="LabyrinthJPManual">''[[Sonic Labyrinth]]'' ([[Sega Game Gear]]) Japanese instruction booklet, pgs. 4-7.</ref><ref>[[Sonic Team]] (September 9, 1999).

In the ''[[Sonic the Hedgehog (film series)|Sonic the Hedgehog]]'' film series produced by [[Paramount Pictures]], Dr. Ivo Robotnik is a brilliant [[human]] scientist, portrayed by [[Jim Carrey]]. Growing up as an orphan and bullied in his childhood, he came to resent the idea of family and humanity in general as a result. After beginning his career, he would work closely with the [[United States (Paramount)|United States]] government, known infamously for his knowledge with robotics and insane behaviors. 

Eventually, Dr. Ivo Robotnik was tasked with investigating the cause of a power outage in [[Green Hills]]. He soon met the cause, a young blue alien named [[Sonic the Hedgehog (Paramount)|Sonic the Hedgehog]] who could move at superhuman speeds. From there, he sought out to capture this creature in order to harness [[Chaos energy (Paramount)|his unlimited power]] for his [[Badnik (Paramount)|own]] [[Eggpod (Paramount)|means]]. However, in the end, he was defeated by the hedgehog and banished to the [[Mushroom Planet]].

Months later, Dr. Ivo Robotnik managed to return to [[Earth (Paramount)|Earth]] with the help of [[Knuckles the Echidna (Paramount)|Knuckles the Echidna]], an alien [[Echidna (Paramount)|echidna]] who was in search of Sonic and the [[Master Emerald (Paramount)|Master Emerald]]. The doctor aided the echidna in his search for the gemstone, only to [[Emerald Eggman|claim it]] for himself and later terrorize Green Hills. However, he was defeated through the combined efforts of Sonic, [[Miles "Tails" Prower (Paramount)|Tails]] and Knuckles.

[[File:IDWDr.Eggman.png|thumb|left|180px|Dr. Eggman, from [[IDW Sonic the Hedgehog Issue 15|''Sonic the Hedgehog'' #15]].]]
In the ''[[Sonic the Hedgehog (IDW comic series)|Sonic the Hedgehog]]'' comic series and its spin-offs published by [[IDW Publishing]], Dr. Eggman is an evil megalomaniacal scientist, whose history is almost identical to his game counterpart's, up until after the events of ''[[Sonic Forces]]''. After the [[War to Take Back the Planet|Eggman War]], the doctor went missing, and his [[Badnik|Badnik Horde]] was left without a leader. Eggman himself ended up in [[Windmill Village]], where he lost his memory and took up a job as a local inventor known as "Mr. Tinker", eagerly helping residents and the community. He was eventually found by the [[Team Chaotix|Chaotix]], [[Sonic the Hedgehog|Sonic]], [[Shadow the Hedgehog|Shadow]] and [[Rouge the Bat|Rouge]], who decided to leave him be, considering him harmless and benevolent now. Soon after, however, the scientist was kidnapped by [[Rough the Skunk|Rough]] and [[Tumble the Skunk|Tumble]] on the orders of [[Doctor Starline|Dr. Starline]], a long-time admirer of his work. Brought to the [[Final Egg]], Eggman had his memory restored by [[Metal Sonic]]. He then began working on the [[Metal Virus]], which he began spreading around the world with his [[Faceship]]. At one point, however, Starline let the [[Deadly Six]] aboard his ship, who took control of Eggman's [[Zombot]]s, forcing the doctor to flee and cooperate with his enemies to stop the Zeti's plan to destroy the world with the Zombots. The villain also got rid of Starline. After the Zombot apocalypse ended, Eggman tried to take advantage of Sonic's absence to dispose of his enemies, but the hedgehog soon returned in time to foil his plan. A little while later, the scientist began working on new Badnik types, called [[Quasi-Badnik]]s. He was also revealed to be the creator of a benevolent robot called [[Belle the Tinkerer|Belle]] while he had amnesia.

===Science===
A potential macrocycle inhibitor of the [[Wikipedia:Sonic hedgehog|Sonic hedgehog]] gene, discovered by a Harvard University research team, was named "Robotnikinin" after Dr. Robotnik. The researchers felt that since Sonic hedgehog was named after the Sega video game character, they should "adhere to the convention" in naming the inhibiting compound after the character's arch-enemy.<ref>{{Cite web |url= http://www.biotechnews.com.au/article/273516/robotnikinin_takes_sonic_hedgehog?fp=4&fpid=1013|title= Robotnikinin takes on Sonic hedgehog|accessdate=2009-02-22 |work= |publisher= www.biotechnews.com|date= 19/01/2009}}</ref>
