Villain Overview
NOTE: This article is about the mainstream video game version of Dr. Eggman. You can find information on other versions on the disambiguation page.
I HATE THAT HEDGEHOG!
~ Dr. Ivo Robotnik's catchphrase.
Citizens of Earth, lend me your ears and listen to me very carefully! My name is Dr. Eggman- the world's greatest scientist, and soon to be the world's greatest ruler. Now witness the beginning of the greatest empire of all time!
~ Dr. Ivo Robotnik aka Dr. Eggman.

Dr. Ivo "Eggman" Robotnik is the main antagonist of the Sonic the Hedgehog video game series. He is a mad genius who is bent on world domination, and the archenemy of Sonic the Hedgehog.

Over the years, Eggman's characterization has switched between him being portrayed as a serious threat, a more comedic and goofy character, an anti-hero or a mix of all. In more recent years, he has notably become more evil and unhinged, his hatred of Sonic the Hedgehog eventually taking him over and driving him to want to destroy everything in the entire world. His age is unknown, measures 185 cm. (6 ft.) and weighs 128 kg. (282 lbs.).

He is voiced by Mike Pollock in the English version, and Kotaro Nakamura in the Japanese version. In the upcoming Sonic the Hedgehog movie, he will be portrayed by the famous actor Jim Carrey.

Personality

Dr. Eggman is the cruel, ruthless, cunning, arrogant, tyrannical, and manipulative ruler of Eggmanland, which consisted of several refineries, factories and industrial areas dotted across the South Island including its capital city, Scrap Brain Zone. After Sonic's victory on South Island the Doctor did not stop his aspirations, but expanded them to include the whole world, with hopes of conquering it and turning into his Eggman Empire, while also building his perfect city, shaped to appease the Doctor's ego - Eggmanland.

Robotnik has a complete disregard for anyone but himself, and is disrespectful in nature, happily mass producing his legion of robots while emitting smog into the atmosphere, and pouring oil into the oceans. His I.Q of 300 gives him a self-important personality, making him vain, egotistical, and narcissistic. However, this is his greatest weakness, as it can cause him to spend too much time being a blabbermouth, and overlooking crucial flaws in his plans. He also has an inability to see his own flaws, considering himself to be the true form of genius. Not content with world domination, Eggman aspires to have his genius run all of creation, and time itself. Realizing his robots alone aren't good enough, Eggman, in later games, decides to team up with more powerful villains than himself, usually supernatural beings. This usually backfires, and ends with utter failure. Because of his tendency's to make poor judgement, Sonic often mocks him, and Sonic and several other characters can see him as incompetent and something of a doofus. However, his goofy behavior can actually work in his favor, as it leads others to be fooled into underestimating him. Despite facing challenges, Eggman is still a serious, conniving, and materialistic guy, and while things might not work in his favor, he will work behind the scenes to make sure he comes out on top. And when everything is going his way, he is a very dangerous and valid threat to all who opposed his plans.

In many cases, Eggman is typically seen as a rival of Sonic, Tails, and Knuckles, and examples of his villainous and vituperative behavior at its worst would be in Sonic Adventure, where he took Amy hostage, and attempted to blow Sonic up; Sonic Unleashed where he lured Sonic into his trap, stunned him, then using a powerful cannon, tore the emeralds from him and used the chaos energy to crack apart the entire world, proceeding to blast Sonic into the vacuum of space; Sonic Colors, where he used a mind-controlled Tails as a living shield, hoping to turn Sonic and Tails against each other; Lost World, where he enslaved Zavok and the other Deadly Six for his own good; and Sonic Forces, when he is completely tired of Sonic and only wants him dead, he tries destroying all life so that Eggmanland can finally rule. Dr. Eggman used to have a more honorable rivalry with Sonic, and saw him as a motivation for his life in general. But in more recent years, Eggman has developed a bigger hatred for Sonic and has started taking his goals more seriously than before.

Powers and Abilities

Usually in spite of his very advanced intellect and scientific know-how (being the smartest character in the series with a recorded I.Q. of 300 (possibly higher)), he fights Sonic and his friends in attacking machinery, but he has two superpowers: super strength and super speed, the latter being somewhat contradictory and inconsistent. Eggman has been shown to be strong enough to destroy pillars, cars, and walls of ice with his fist with as much ease as Knuckles. He also has exceptional marksmanship, gunning down Tails's tornado at least twice. In addition to his mechanic skills, Eggman can also be quite manipulative, and convince people that he is a kind old soul. However, when Sonic is pitted against him, his speed, strength, marksmanship, and manipulation appeared to be poor.

Appearance

He is a tall, bald, obese human with a height of (6.1.) 185 cm (6' 1") and a Weight. 128 kg (282 lb). He has an oversized mahogany mustache, pale skin and blue eyes, as revealed in Sonic 06. He also has long lanky limbs, contrasting his fat, egg-shaped body. He possesses facial features such as a round face, pointed nose and a toothy smile. He wears grey hexagonal goggles, navy blue pince-nez glasses, white gloves, a red jacket with yellow cuffs and a white zip, and black pants and shoes.

Creations

Egg Mobile

The Egg Mobile, also known as the Egg Pod or the Egg-o-matic hovercraft, is a famous creation of Dr. Robotnik. He uses it as his personal ride for the majority of Sonic the Hedgehog games. He also uses it to fight Sonic sometimes with some add ons:
  • Wrecking Ball
  • Fireball Cannon
  • Spike
  • Mine Dropper

Metal Sonic

Main article: Metal Sonic

Arguably more dangerous than the Doctor himself, this cruel and relentless robot has an intense spite towards Sonic the Hedgehog, rivalling or exceeding Dr. Robotnik's hatred of the blue tinted insectivore. Metal Sonic was loyal to his evil creator in the 2-D games, and some of the 3-D games, but sometimes, Ivo Robotnik himself struggles to handle this metallic speed demon.

Eggman Fleet

The Eggman Fleet is an immense group of flying battleships built by Dr. Eggman. Bristling with guns, cannons and robot armies, it is capable of laying waste to nearly everything in its path. Built for the purpose of helping the evil scientist take over the world.

Egg Dragoon

CBEMXasXEAA5igJ
The Egg Dragoon is known for being the most powerful of Eggman's creations. It has a notable size advantage against most of its enemies and its drill is made for attacking foes. In Sonic Unleashed it uses its drill in order to tear the earth apart, meaning it must be extremely powerful. It can also do elemental slams with its drill.
  • Ice
  • Electricity
  • Fire

Its cannon is obviously made for shooting. The rebuilt Egg Dragoon is a lot more lethal. The cannons shoot even more fire and it can shoot ice from its claws. It can shoot both multiple small at the same time but can as well shoot a big wave. Egg Dragoon is a highly detailed robot with a lot of dragon-like details. It has dragon like wings, a drill, big claws on its two feet, and a cannon. Its primary color is bright red, matching Dr. Eggman, but it also has light blue wings and an iron-like color on the drill and cannon. In Sonic Unleashed, Egg Dragoon is the second to last boss battle. It was heavily researched and based of on Sonic's movements, and was supposed to be the ultimate weapon to kill off Sonic. The fight it had with Sonic was intense, and it destroyed layers of the earth during the fight, but ultimately Eggman and his robot failed, and Sonic was sick of him and tore the whole robot apart and then threw Eggman away. The design in the mobile version of sonic unleashed is very different than the console version, as well as it is the final boss instead of Dark Gaia. In Sonic Generations, the Egg Dragoon is rebuilt and even more dangerous. It appeared out of nowhere really, but Sonic still managed to defeat it.

Egg Dragoon appears in the Sega video game, Sonic Forces. It is similar to how it was in the other games, except this time around, it is one of the first bosses in the game. This is interesting considering in every other game it has been one of the last boss battles. It is fought in Green Hill Zone. It is unknown if it will return later in the game.

Egg Beetle/Lancer

These two insectoid robots are fought two times in Sonic Unleased. The Egg Beetle is fought at the beginning of the game, while The Lancer is fought at the very end of the game.

The Egg Beetle, despite its name, resembles a spider more than anything. Its lancers have a molten fire color on them. It levitates above the ground and can fly at very high speeds.

Egg Lancer Robotnik

The Egg Lancer

The Egg Lancer is very similar to the Egg Beetle in terms of design, except this time it has a more intimidating and fierce design, along with an even more futuristic design with multiple laser guns that it uses.

Badniks

Main article: Badniks

Small, weak, but mass-produced, and attacking in large numbers, and extremely versatile, these mechanical fiends come in many great varieties and they served Doctor Robotnik and they will hunt down Sonic the Hedgehog and anyone else who opposes the "good" Doctor.

Eggman's themes over the years

Over the years Dr. Robotnik had many musical pieces associated with him. Most of these were boss music in the classics, however, since the Sonic Adventure era the good doctor started getting distinct themes even outside of boss fights, such as Paul Shortino's "E.G.G.M.A.N." or the dark "Theme of Dr. Eggman" leitmotif which had been used since the 2006's Sonic the Hedgehog. "E.G.G.M.A.N." is considered his official and main theme, while Theme of Dr. Eggman is considered to be a warning / danger theme.

Appearances in other media

This article is about the video game version of Dr. Ivo "Eggman" Robotnik - you can find more information on his appearances in other media disambiguation page.

Animation

There have been five animated TV series featuring Dr. Robotnik. The first was Adventures of Sonic the Hedgehog where he was voiced by Long John Baldry. Doctor Robotnik was the series' main antagonist, being portrayed as a villain who sought to rule the planet Mobius for no reason other than the fact that he appeared to be motivated by the act of being evil. While the threat he posed to Sonic the Hedgehog and Mobius varied from episode to episode, he was generally portrayed as incompetent and immature, with a tendency to mistreat his dimwitted Badnik sidekicks Scratch and Grounder, and, many times when Sonic foils his plans, utter the catchphrase "I hate that hedgehog!". The mannerisms and catchphrases of his television counterpart has become highly memetic.

In the animated series Sonic the Hedgehog, Jim Cummings voiced Dr. Robotnik (whose real name was Julian, which was original to the Sonic the Hedgehog series). This version of Dr. Robotnik was initially portrayed as a fearsome dictator, darker and more serious than his much sillier counterpart in Adventures of Sonic the Hedgehog. Doctor Robotnik rules over his evil industrial city known as Robotropolis, and he is accompanied and joined by his two most favored allies, his robotic pet Cluck who is the only one thing he treats with compassion, and his unscrupulous nephew Snively who desires power and his uncle's downfall. As season 2 was more lighthearted than season 1, Robotnik was later depicted as an evil but incompetent villain rather than the fierce, dangerous, and intimidating foe he was originally shown to be.

Sonic Underground featured Robotnik in a style similar to the previous Sonic the Hedgehog animated series, but much more lightheartedly; he maintains less control and he is far more bumbling. He was voiced by Gary Chalk.

In the 2-episode OVA Sonic the Hedgehog: The Movie, Dr. Eggman tells Sonic that he has been banished from Robotropolis (Eggmanland in the Japanese release) by a metallic doppelgänger of himself called Metal Robotnik (Black Eggman in the Japanese release). It is later revealed that the mecha was piloted by Eggman himself, in a scheme to lure Sonic into his base and copy his DNA for his new Hyper Metal Sonic robot. Eggman was voiced by the late Junpei Takiguchi in the Japanese version, and by Edwin Neal in the English dub.

In Sonic X, Doctor Eggman (which he is usually referred to in this series, though his real last name in-universe is Robotnik as in the games), along with other Sonic characters, including Sonic himself, are accidentally transported from their own world (Mobius), to Earth. In the final season, Eggman returns to his universe and reluctantly joins forces with Sonic and his friends to fight the new menace called the Metarex before continuing to try building his own evil empire in his attempts to achieve world domination. This incarnation is voiced by Chikao Ōtsuka in the Japanese version, and by Mike Pollock in the English version.

Dr. Eggman appears as the primary antagonist of the Sonic Boom animated series, with Mike Pollock reprising his voice role. Eggman's physical appearance was the most drastically changed of the cast, now appearing to have a buff upper body and wearing a militaristic uniform, as well as having a fully brown and smoother mustache. He also appears to be less intelligent and much more childish than his mainstream counterpart.

Doctor Eggman also makes a brief appearance in the anime Hi sCoool! SeHa Girl. In the middle of the Sega Hard Girls' first exam, Eggman hacks into the game world and begins to wreak havoc until Sonic appears to aid the girls in stopping him.

Comics

When the first Sonic the Hedgehog title was released in 1991, Sega of America developed an origin for Sonic the Hedgehog and Dr. Robotnik which diverged from the back-stories created in Japan by Sonic Team. In this back-story, set on the planet Mobius, Dr. Ivo Robotnik was originally a benevolent scientist named Dr. Ovi Kintobor ("Ivo Robotnik" with the names spelt backwards; also, "ovi" is the Latin prefix meaning "egg"), a friend to Sonic who helped to develop the hedgehog's super-speed. In the Sonic the Comic, Kintobor was merged with a rotten egg and transformed into Dr. Robotnik after tripping over a cable with a rotten egg in his hand and suffering a severe electric shock. The result created Dr. Ivo Robotnik, who instantly became the opposite of the good Dr. Kintobor and would occasionally use the word "egg" in some words, with an example being "eggsactly". In the United States, a different storyline was featured in a 14-page promotional comic book written by Francis Mao and designed to promote the game. The origin story was also adopted by Sega Europe, featuring in British publications such as the book Stay Sonic and later the comic book series Sonic the Comic, which was published from 1993 until 2002. In Sonic the Comic, Dr. Robotnik was the dictatorial ruler of planet Mobius for most of the comic's first 100 issues, while Sonic also had access to an AI computer program based on the personality of Dr. Kintobor. Initially, Robotnik's appearance in Sonic the Comic matched that of the video games, but from issue 22 onwards the comic adopted his design from the Adventures of Sonic the Hedgehog cartoon show.

Also in 1993, Archie Comics began publishing its Sonic the Hedgehog comic book. The series is in a sense, a very loose continuation of ABC's Sonic the Hedgehog animated cartoon; as well as a mad scientist, Robotnik is a portrayed as an oppressive and magisterial dictator who took control of Sonic's hometown during a coup d'etat. In recent years, the plot of the comic has changed to incorporate elements from the video games, with Robotnik being replaced by his more traditional videogame counterpart.

Live-Action

Youtube actor DJ Hazard portrays Dr. Robotnik in the 2013 short fan-film Sonic, by Eddie Lebron. This version is more in line with his darker SatAM counterpart, being an unsympathetic, ruthless, cold, and brutal tyrant and holding a disgust towards Mobians, or "South Islanders", as they are called in the fan film. Parallel to SatAM and Archie Comics, he started off as Dr. Julian Kintobor, before deciding to become a totalitarian dictator by establishing his Eggman Empire and set out to conquer Mobius.

Eggman is set to appear as the main antagonist of the upcoming Sonic film, portrayed by actor Jim Carrey. Currently, as the film is a live-action animation hybrid, it is unknown if Eggman will be a live-action or animated character.

The only person that smart… is me!
~ Eggman explaining about what happened after Sonic Colors and requiring the help of Robotnik (a.k.a. Classic Eggman) to complete modifying the Time Eater.

~ Eggman agreeing to Robotnik's idea about going back and getting his teaching degree.
Transformation 101. Bunnies to Badniks. Boom! Instant army! It needs to be a big army if I'm taking over the world below.
~ Eggman explaining the creation of Badniks to the Zeti in Sonic Lost World.
I hone your abilities. I equip you with the most powerful mechs I can create. I even give you a giant sandwich! And you still disappoint me.
~ Eggman admonishing the Deadly Six in Sonic Lost World.
When it's the only thing keeping six angry Zeti from controlling my mechs! You moronic hedgehog!
~ Eggman after Sonic deprives him of the Cacophonic Conch he was using to control the Deadly Six in Sonic Lost World.
Thanks to Sonic, everything's gone "cattywampus!
~ Eggman explaining how it's Sonic's fault he lost control of the Deadly Six.
I don't like working with my most hated enemies any more than you do.
~ Doctor Eggman allying himself with Sonic and Tails to stop the Deadly Six.
If you weren't always destroying them, I wouldn't need so many.
~ Doctor Eggman explaining to Sonic why he builds so many military factories in Sonic Lost World.
I think I liked it better when I was trying to destroy you.
~ Eggman when Tails insults him on the way he designed Cubot's voice chip.
Actually, nothing bites more than having to listen to this dreadful conversation.
~ Eggman as Sonic and Tails argue about trusting him to stop the Extractor.
I'll get fat from eating your black hearts, you Eggman wannabes!
~ Eggman threatening Zavok and Zazz in the Frozen Factory.
I'll burn your worlds you rebellious scum! I'll destroy everything you love and make you watch!
~ Eggman threatening Zavok and Zazz after they rise up against him and use his Extractor to destroy Sonic's world.
As long as I can still strangle a Zeti, my hands are fine.

I'll find another conch, and the Zeti will be mine once again. Only next time I'll make them stronger!
~ Eggman after being defeated by Sonic in Sonic Lost World.
WHAT'S WRONG WITH MY MUSTACHE?!
~ Doctor Eggman hearing Orbot and Cubot talking about his halved mustache at the end of Sonic Lost World.

~ Doctor Eggman speaking to Shadow and Amy.
You're history!
~ Dr. Eggman before the player takes him on in Sonic Dash.
We've got an intruder! Shadow has entered the facility! Defense Squad Jackal has already been completely annihilated! All available troops, intercept that blasted hedgehog by any means necessary!
~ Dr. Eggman alerting soldiers and Badniks to stop Shadow from destroying his facility.
Rrrgghh! I went to great pains to get the best mercenaries around, and He's still totally wrecked the Defense Squad! SHADDDOOWWRRRGH!
~ Dr. Eggman for seeing Jackal Squad get harmed by Shadow the Hedgehog.
Ugh. At least the analysis of the stone was completed yesterday, but... No, I still can't let this facility be destroyed! Is there ANYONE left out there!?
~ Dr. Eggman still impressed to complete the analysis of the Phantom Ruby, but still waiting fro anyone to protect his facility.
Hey, you! I know you can hear me! You're the captain of Squad Jackal, aren't you?! Your squad was useless! Go clean up their mess already!
~ Dr. Eggman to Infinite.
Sonic, how I hate him. And all of that loathing has been focused into this invincible instrument of destruction. Every defeat, every humiliation at the hedgehog's hands will be returned a thousand-fold by my unstoppable creation. This is my dream come true. With this invention, I can expand the Eggman Empire across the globe and conquer the world!
~ Doctor Eggman in the introduction of Sonic Forces.
The sun will fall upon you all. BOOM! THE END!
~ Dr. Eggman theatens the Resistance.
(laughs) You think you can stop the sun? You'll burn like a moth drawn to a flame! It's over!
~ Dr. Eggman to the Avatar.
You never fail to surprise me, Sonic. I didn't believe Infinite could lose. Victory will be so much sweeter when I defeat you. Don't think this is over yet, you blue nuisance. My plan just went into overtime!
~ Doctor Eggman after watching Sonic and Avatar defeat Infinite.

Trivia

  • The character was originally designed as "Dr. Eggman" for the Japanese audience and adapted as "Dr. Ivo Robotnik" in the English release. Although references to both names, such as the "Eggman-01" designation of Wing Fortress in Sonic the Hedgehog 2 or the "Robotnik Winter" level in Sonic Triple Trouble, were present in both Japanese and English versions of the games, there was no unified canon on the naming convention until Sonic Adventure series. Sonic Adventure introduced "Eggman" as Dr. Robotnik's nickname by Sonic, which he later adopted as his own supervillain alias by Sonic Adventure 2 for the Western audiences. For the Japanese audiences, Sonic Adventure 2 introduced Gerald Robotnik and Maria Robotnik, Eggman's relatives, officially establishing "Robotnik" as his real surname in both canons, along with the words "Robotnik Empire" appearing behind Eggman during a cutscene. The character was mostly referred to as "Doctor Eggman" after that, although references to his real name still appeared from time to time.
  • The Roboticizer

    The Roboticizer

    The most well-known, yet infamous invention by Doctor Robotnik is the Roboticizer, a machine which makes living organisms, even animals, undergo the state of Roboticization, transforming them into fully mechanized robots devoid of free will. This is used in the SatAM, and Sonic Underground cartoons, and in the Archie comics. However, in the games, he puts small animals into robot shells to power them, instead of transforming flesh into robotics.
  • Eggman was originally voiced by Deem Bristow in English from Sonic Adventure to Sonic Heroes (though Bristow's voice clips were reused in Sonic Riders). In Japan, though, he was at first voiced by Masaharu Sato in SegaSonic and Chikao Otsuka from 1998 to 2015.
    • Eggman is notable for being the only character to keep his Sonic X English voice actor. All the others changed voice actors in 2010.
  • In the games, comics, and anime Sonic X, Dr. Robotnik (also called Dr. Eggman) idolizes his grandfather Professor Gerald Robotnik, and in SatAM, he cared for his robot pet Cluck. To date, Gerald Robotnik and Cluck are the only people he loves apart from himself.
  • In Sonic SatAM, Robotnik claimed to have a metallic heart. This could mean his heart is indeed cybernetic, or he may have meant this metaphorically.
  • Sonic Boom is the only franchise in which Doctor Eggman is not obese.
  • Although he is portrayed with cybernetic or mutated red eyes in the early cartoons, and in the comics, his eyes are a dark blue in Sonic '06.
  • In a 2-D artwork, Eggman is portrayed as having pencil thin arms, and no chin, but in games, he has a more masculine face, a big chin and thick muscular arms.
  • Fans of the Sonic games often debate intensely which incarnation of Doctor Robotnik is the best. Some consider the one from the Sonic SatAM cartoon to be the greatest, mainly because he appeared to be crueler than his game counterpart, and had a tight global grip over Sonic's home planet of Mobius. SatAM Robotnik fans also believe Sega's Eggman is too sympathetic to be considered a good villain, and see him as a harmless goody-good. However, many still believe the mainstream version is the greatest, as he has a comedic charm, is wildly inventive, colorful, and still can be very intelligent and cruel, as in Unleashed, he actually captured Sonic, disfigured him and shot him into space, intent on killing him, and in Sonic Adventure 2, he came very close to killing Sonic. Sega's Eggman is also cruel enough to burn up Wisps and attempt to turn everyone into mindless drones in Sonic Colors.
  • Eggman's first name 'Ivo' is simply a backwards spelling of the Latin word 'ovi' which means 'egg'.
    • Similarly, in the Archie Comics and in the Fleetway comics, his original last name is "Kintobor" which is backwards for "Robotnik".
  • The Robotnik Prime

    Robo-Robotnik, who also called himself the "Robotnik Prime".

    "Robotnik" is an actual word, meaning "worker" or "slave" in the Slavic languages. This could explain his preference for using enslaved animals and robots as his minions.
    • A potential inhibitor of the Hedgehog signaling pathway was dubbed "Robotnikinin" in honor of Dr. Ivo "Eggman" Robotnik, while the SHH ("Sonic Hedgehog") gene/protein were named in honor of Sonic the Hedgehog.
  • His basic characteristics, such as his clip-less glasses, toothy smile, and mustache are based on the features of U.S. president Theodore Roosevelt.
  • Eggman's character design has gone through more changes than any other Sonic series character.
  • In Sonic the Comic, Robotnik is worshiped by a sinister underground cult known only as D.R.A.T., who are his fanatical "supporters" as well as called him both "The Doctor" and "The Master" and are more than willing to do everything in their power to return their "idol" to power and control over the planet Mobius and all of its inhabitants.
  • The cartoon show Adventures of Sonic the Hedgehog was the only English-speaking series prior to Sonic X to have Dr. Robotnik referred to as "Eggman" in the episode "Lifestyles of the Sick and Twisted" by Tails.
  • Also in the episode "Road Hog" of Adventures of Sonic the Hedgehog, Dr. Robotnik is referred as "The Master" by his brainwashed slaves who are under a hypnotic trance due to the Mind Pollens derived from Colonel Stench's special artificial flowers.
  • In Dr. Robotnik's Mean Bean Machine, his pupils are clearly white while on the box art and in the show, they are colored red.
  • In Mario & Sonic at the Olympic Games, Eggman is a Skill character, but in the series, he was a Power character.
  • Tails and Eggman were the only characters who are better known by their nicknames.
  • His Sonic Channel artwork was the base of two 3D-model poses: first for his Trophy in Super Smash Bros. Brawl and again for Sonic Unleashed.
  • The "Soda Can" item in Sonic Free Riders has a picture of Dr. Eggman on it.
  • Despite being the main villain of the series, Eggman has been playable in numerous games.
  • The only game he has never made an appearance on, not even a cameo was Sonic and the Black Knight. Despite this, one of the collectible items in the game, the Joker Card, has his logo on it, and the Legacy mission had his robots as enemies.
  • An unused line of Omochao's from Sonic Adventure 2 hints at the possibility that Dr. Eggman's mustache may be fake.
  • Sega did not model any eyes for Dr. Eggman's 3D model in all games except Sonic the Hedgehog (2006). In the 2006 game, his eyes are blue.
    • Eggman did not wear his goggles in Sonic the Hedgehog (2006).
  • An early version of Eggman was originally one of the choices to be the main character and even as the hero of the game that would become the first game of the Sonic the Hedgehog series.
  • There is an Internet meme from Adventures of Sonic the Hedgehog where Robotnik's line "Snooping as usual I see" was shortened into "PINGAS". This joke was even used in the Archie comics.
  • While the first name "Ivo" has never reached Japanese Eggman profiles, it did once get referenced in Sonic Jam (albeit in the English digital manual for Sonic the Hedgehog).
  • In the game of Football: Virtua Striker 3, Dr. Eggman appears in a secret team called "FC Sonic" that make up Sonic, Tails, Knuckles and Amy.
  • It is revealed in Sonic Generations that before Eggman decided to become an evil villain, he was offered a teaching degree (which Dr. Robotnik said he was going to try to get).
  • In Sonic the Hedgehog 4: Episode I, the back of the cards in Casino Street Act 2 has Eggman's face on them.
  • In every 3D main Sonic game since Sonic Unleashed, a running gag with Eggman has him shouting the word "shut up" (usually around the last cutscene).
    • However, in the second to last cutscene in Sonic Colors, he said "shut up" to his own PA announcements, which means he could be tired of his own amusement park plans failing.
  • The enormous mustache that Eggman wears in his various incarnations give him a passing resemblance to iconic Looney Tunes villain Yosemite Sam, although Eggman's is larger in size than Sam is.
  • The most recent theater poster for Walt Disney's videogame-based film Wreck-It Ralph prominently displays Dr. Eggman and Sonic on it. Eggman himself appears in the film as a cameo as well as member of the villains support group called Bad-Anon, though he does not have a speaking role.
  • His jacket resembles legendary pop singer Micheal Jackson's Thriller jacket.
  • Eggman's pose for Sonic Colors artwork is very similar to his pose in Sonic & All-Stars Racing Transformed, only with his hands in different positions.
  • Eggman's pose for Sonic Unleashed is a near identical pose to his Sonic Channel.
  • An unused quote in Sonic Colors has Eggman stating that the power of the Chaos Emeralds are weaker than the Wisps' Hyper-Go-On energy.
  • Eggman has a recurring leitmotif, outside of "E.G.G.M.A.N.". It plays in Sonic 06, Sonic Unleashed (most notably the Eggmanland's hub world theme) and in Sonic Colors (plays in cutscenes before some boss fights and while in Sonic Simulator although the latter plays the music in an 8-bit style remix). Eggman has a combined theme in Sonic 06 with Elise called "Elise Goes Alone".
  • Eggman has a huge fondness for his own food he cooks in Sonic Unleashed, especially his "Poppin' Eggcorn".
  • Eggman's ultimate ambitions appear to involve building theme parks despite having ulterior motives. Such cases are Eggmanland in Sonic Unleashed, all the parks in Sonic Colors and possibly counting Sonic Free Riders.
  • Eggman outruns Sonic in many games, such as Sonic and Knuckles and Sonic the Hedgehog 2.
  • The Eggmanland

    The Eggmanland

    Dr. Robotnik/Dr. Eggman along with his own namesake theme parks, share similarities with the sinister monarch King Bowser (with World Bowser and Bowser Land) from the Super Mario Bros. franchise and the all-around trash-talker Cartman (with Cartmanland) from the South Park TV series.
  • Starting with Sonic Colors, his plots now seem to be a fusion of his classic goals of kidnapping animals and his modern plots of harnessing the energies of alien and supernatural beings. In Sonic Colors, he kidnaps and drains the energies of the Wisps. In Sonic Generations, he kidnaps Sonic's friends and harnesses the Time Eater's abilities. In Lost World, he kidnaps the animals of classic games and drains the entire world's life force, while at the same time attempting to hone the Deadly Six's abilities.
  • There's a running gag that Eggman frequently finds powerful beings that he tries to control in order to take over the world, only for them to betray Eggman for their own agendas. Currently, the Time Eater and Infinite are the only ones who didn't betray Eggman at any point.
  • Like some of the other characters, Eggman's favorite food has yet to be confirmed. That said, it can be noted that in Sonic Unleashed, he is shown to have a love of submarine sandwiches as shown in a cutscene where he consumes an entire sandwich in less than 10 seconds.
  • Doc Eggman

    Doc

    His nickname "Doc" (aside from his other alias "Doc Eggman") is a reference to the nickname of the Marvel supervillain Doctor Octopus (also known as "Doc Ock") from the Spider-Man comic books, the nickname of the time-travelling genius Dr. Emmett Brown (also known as "Doc Brown") from the Back to the Future franchise, and the famous catchphrase "what's up doc?" of the famous Looney Tunes character Bugs Bunny.
  • His other phony nickname "King Doc of Toreggmania" from Sonic Free Riders is a loose reference to the name "Trogg" (by scrambling and reassembling the non-existent name "Toreggmania" into 5 letters, "T-R-O-G-G") the creature who serves the malicious spirit known as the Evil One from the comic book series Sonic the Comic.
