Sonic the Hedgehog (TV series)
Dr. Robotnik was a heartless, diabolical tyrant who had already conquered most of Planet Mobius. He was good-natured, up until he became power hungry. His plans of conquering Mobius was assured except for the Freedom Fighters, led by Princess Sally and Sonic the Hedgehog. Unlike in Japan's continuity, the antagonist was only known as "Dr. Robotnik", with no hint of his first name, until later in the series where it was retconned to Julian
Sonic the Hedgehog: The Movie
Doctor Robotnik appears in Sonic Underground as the tyrannical "leader" of Mobius. After Queen Aleena gave birth to three young hedgehogs, the Oracle of Delphius appeared to her, reporting of Robotnik's takeover, thus, the three hedgehog were separated.
In the anime series Sonic X, Dr. Eggman was born on Earth, but got somehow flung into Sonic's world. He has two somewhat absent-minded sidekicks, Bocoe and Decoe, and a messenger robot named Bokkun. By mistake, he and Sonic and co. arrive there, meeting Christopher Thorndyke, among others. He mainly schemes diabolic plans for world domination but Sonic and his friends frequently stops the doctor's plans and protect humanity. Eventually they had to go back to their world because the alternate universes containing the planets were fusing together, and would only stop if Sonic and co. leave. In the third season his role as the main villain is taken over by the Metarex and their leader Dark Oak, resulting in the doctor having to side with Sonic and his friends in order to stop the Metarex.
In the Sonic Boom franchise, Dr. Eggman is the evil, yet quirky supervillain who constantly menaces Seaside Island with his legions of robots in his quest to take over the earth. From his island fortress, he concocts many evil (and zany) schemes to ensure the fulfillment of his ambitions, the destruction of his enemies or both, with the aid of Orbot and Cubot, but is stopped and beaten at every turn by his arch enemy Sonic and his crew.
Sonic the Hedgehog (manga)
In the Sonic the Hedgehog serialized manga series published by Shogakukan, Dr. Eggman is a long-time arch-nemesis of Sonic the Hedgehog. Early on in the Shogaku Ninensei manga's run, evil doctor has been looking up for him and finally finds out the connection between Nicky and Sonic. His goal is to catch Sonic and make his lackey as part of taking over the world. In CoroCoro Comics Special manga strips, Eggman has army of robot soldiers and Badniks, but he also takes secret alter ego Dogman, a policeman of the Hedgehog Town. As Dogman, he is capable of teaming up with Anton Veruca, the Number One Hooligan in Hedgehog Town.
In the Sonic the Hedgehog comic series published by Archie Comics, Dr. Robotnik was a heartless, diabolical tyrant who had already conquered most of Planet Mobius. He was good-natured, up until he became power hungry. His plans of conquering Mobius was assured except for the Freedom Fighters, led by Sonic the Hedgehog and Princess Sally.
Sonic the Comic
Ivo Robotnik was created during a laboratory accident involving the goodly scientist Ovi Kintobor, a rotten egg and the Chaos Emeralds. During the series he managed to send Sonic forward in time by six months, during which time he managed to conquer Mobius. Sonic and his friends formed a group of Freedom Fighters with the aim of overthrowing him, of which they eventually did which caused Robotnik to lose his sanity.
In the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing, Dr. Eggman is an evil megalomaniacal scientist. In the aftermath of his war against the Resistance for control over the world, he had disappeared. He later resurfaced in an idyllic town, completely amnesiac of previous events. He soon took up the new alias "Mr. Tinker" and started to gain the trust of the villagers, as well as Sonic.
Although the character was designed as Dr. Eggman in Japan since the original Sonic the Hedgehog, he was first known as Dr. Robotnik in Western countries. The name Dr. Ivo Robotnik was invented by Dean Sitton for the original Sonic the Hedgehog English instruction manual (as shown above). The first name 'Ivo' was picked primarily because of the phonetic similarity to the word 'evil' (some drafts of the unpublished Sonic Bible also specify that it should be pronounced "ee-vo", rather than "eye-vo") but also because Sitton's sister at the time had a boyfriend from Croatia named Ivo. In addition, Ivo is the reverse of ovi, which is the genitive singular form of the Latin word ovum, meaning "egg." The term robotnik had been coined earlier as a worker or automaton. Other names were also thought of by Dean Sitton, like Mister Badwrench, Mr. Bad Year, Fatty Lobotnik and Dr. Badvibes. The localization was also used in other officially licensed media (such as Adventures of Sonic the Hedgehog and Sonic the Comic).
Despite his western name, the name "Eggman" can be found in various games. In turn, the "Robotnik" moniker occasionally reached Japanese shores, such as in the bottom of the SegaSonic the Hedgehog Arcade flyer, the name of Robotnik Winter Zone of Sonic the Hedgehog Triple Trouble, and the banners decorating Spring Stadium Zone in the Sega Saturn edition of Sonic 3D Blast. It was not until Sonic Adventure that Sega of America decided to merge the two names together; this resulted in Eggman being his alias and Robotnik being his true last name. This was subsequently confirmed to be the case by Yuji Naka in an interview.
Since then, he has mostly been known in America as "Eggman", with the use of the name "Robotnik" becoming rare. Sega of America has listed his identity as Doctor Ivo "Eggman" Robotnik at least once, and has recognized both the first name Ivo and the last name Robotnik as recently as 2011 in the videogames and 2015 in social media. Despite that, Sega of Japan does not acknowledge an official complete name; the Japanese Sonic Channel lists his full name as unknown, and his in-game profile in Sonic the Hedgehog 4: Episode II lists his real name as a mystery.

A potential macrocycle inhibitor of the 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.
Over the years, Dr. Eggman has been used in a variety of merchandise, from collectible pins and plushies to specialized notebooks and clocks.
The character has been well-received, going on to become one of the most well-known villains in gaming. GameDaily ranked him number one on their list of "Top 25 Evil Masterminds of All Time" article, stating "Out of all the evil masterminds in video games, none are more despicable, more cunning, or more menacing". IGN listed him at number nine above Mario-series villain Bowser in their "Top 10 Most Memorable Villains" article, calling him "PETA's videogame public enemy number one", and has also commented that his character is a "pretty clever riff on Teddy Roosevelt" that has added to the attraction of the series. He was featured at number three in a "Reader's Choice" edition of GameSpot's "Top Ten Video Game Villains" article, which noted a massive complaint from fans at his exclusion from the original list. Eggman was also named the 15th most diabolical video game villain of all time by PC World. Game Informer notes that in Sonic Chronicles: The Dark Brotherhood, "Eggman's villain ego shows some amusing tarnish after constant defeat at the hands of Sonic."Boy's Life magazine listed "Dr. Eggman / Dr. Robotnik" as number one on their top five video game villains, saying "Two names, one big problem for Sonic the Hedgehog". In the "Top 100 Videogame Villains" of IGN, in 2010, Dr. Eggman was ranked at 11th place.

- An unused line of Omochao's from Sonic Adventure 2 hints at the possibility that Dr. Eggman's mustache may be fake.
- Sega didn't model any eyes for Eggman's 3D model in all games except Sonic the Hedgehog (2006). Eggman's eyes are blue in this.
- An early version of Dr. Eggman (an over-sized Theodore Roosevelt in pajamas) 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.
- The name Dr. Ivo Robotnik may be a reference to its appearance as Ivo backwards is Ovi, which means "egg" in Latin.
- "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.
- 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.
- In Sonic the Hedgehog 4: Episode I, the back of the cards in Casino Street Act 2 has Eggman's face on them.
- Eggman is one of the two canon characters throughout the series originally based off of a political public figure (Theodore Roosevelt) let alone a real person. The other is Sonic, whose personality is based off of Bill Clinton.
- On December 3, 2012, a woman actually named Susan Eggman was elected a member of the California State Assembly. And on June 4, 2014, a man actually named Michael Eggman was elected congress representative of Central Valley, California. So now, Dr. Eggman is the only character in the series who is not only based off of a political public figure, but also shares a name with not one, but two.
- His pose for Sonic & All-Stars Racing Transformed is very similar to his pose in his artwork for Sonic Colors, only with his hands in different positions.

- Although Dr. Eggman himself doesn't appear in the Super Smash Bros. games, he does appear as a trophy in Super Smash Bros. Brawl, and is also indirectly alluded to in a Codec conversation, where Solid Snake (voiced in the Japanese versions by Akio Otsuka, who is the son of Chikao Otsuka, who voiced Dr. Eggman) mentions that he "for some reason doesn't like [Sonic]." Coincidentally, Solid Snake's father, Big Boss, was voiced by the late Chikao Otsuka in Metal Gear Solid 4: Guns of the Patriots (at the time under development), whose character also had a goal similar to one of Eggman's (specifically, Big Boss sought to subject the world to becoming a warzone to allow soldiers freedom, a warrior utopia known as Outer Heaven, similar to Eggman's scientist utopia of the Eggman Empire. Both plans also stemmed as a response to perceived unjust actions against people they looked up to The Boss for Big Boss, and Professor Gerald Robotnik for Dr. Eggman).
- Eggman was the very first human character to ever appear in the Sonic franchise.
