(Unwritten rule here seems to be to use Robotnik if the original localization used it - Sonic Adventure is the last game to use Dr. Robotnik in a significant fashion, therefore he should primarily be Robotnik in SA1 info.)

Dr. Eggman, Sonic Adventure 2

Template:Character Dr. Ivo Robotnik (ドクター・ロボトニック Dokutā Robotonikku?, lit. "Doctor Robotnik"), better known by the alias Dr. Eggman[1] (ドクター・エッグマン Dokutā Egguman?), is a fictional human character from the Sonic the Hedgehog series. He is the arch-nemesis of Sonic the Hedgehog and the primary antagonist of the franchise. As an obese scientist with an IQ of 300 who dreams of dominating the world, his constant plots to create his Eggman Empire are endlessly thwarted by Sonic and his friends.

While the doctor's plans initially consisted of building up incredible armies by turning animals into robots and using them to dominate the land, Dr. Eggman's schemes have since branched into much more global threats as he built war machines, used nuclear devices to threaten entire nations, and even relied on mythological and ancient deities bent on destruction to achieve his goals. Eventually, the mad scientist has gone as far as to target the entire universe and cooked up schemes to control time and space itself.

While all these plans end in failure thanks to the continued efforts of Sonic and his friends, the mad doctor somehow is always able to slip away from certain death or imprisonment and escape at the last moment, making him a constant threat to the universe and a thorn in Sonic's side.

Concept and Creation

Robotnik 50

Dr. Eggman's original design in 1991.

In the month April 1990, Sega petitioned its research and development department, AM8 (later became Sonic Team), to create a character who would replace Alex Kidd as the company's mascot, as well as compete against Nintendo's flagship character, Mario. A caricature of Theodore Roosevelt in pajamas was among the proposed designs. Combined with the idea of an egg-shaped character, it eventually became the basis of the visual design for Dr. Eggman. In creating the "bad guy" for the Sonic series, the development team wanted a character who was "the opposite of Sonic"; a character who represented "machinery" and "development" to play on the then-growing debate between developers and environmentalists. The character was also designed to be easy for children to draw.


One of the concepts for the hero of what eventually would be known as Sonic the Hedgehog.

The original English instruction manual for his 1991 debut game Sonic the Hedgehog described the character's full name as "Doctor Ivo Robotnik" while the Japanese version's instruction manual for the same game called him "Doctor Eggman". In 1998's Sonic Adventure, the character was called both "Doctor Robotnik" and "Doctor Eggman" in the English version, with all following English releases to date referring to him as "Doctor Eggman". Yuji Naka has explained that Robotnik is the character's true last name while Eggman is a "common name taken after his shape." While the Robotnik name is still occasionally recognized, Eggman's profiles such as the one on the Japanese Sonic Channel and Sonic the Hedgehog 4: Episode II list his full birth name as unknown.


Early Life

In childhood, the young Robotnik looked up to his grandfather, Prof. Gerald Robotnik as a hero, and believed him to be a great man who had done his best to help mankind. Thus the doctor decided to follow in his grandfather's footsteps and became a scientist, as well as pursue a teaching degree (apparently because he liked telling people what to do). However, he became obsessed with the idea of an entire world under his rule, and using his unmatched genius, began his plans.

At some point after setting out on his quest for global domination, Dr. Robotnik met Sonic the Hedgehog. While the nature of their meeting is unknown, the two of them eventually became rivals, with Sonic proving to be Dr. Robotnik's greatest enemy. After their meeting, Dr. Robotnik made several attempts to conquer the world, but at every turn, his plans were laid to waste by Sonic.[2]

Sonic the Hedgehog (1991)

Robotnik’s first appearance was in the 1991 video game Sonic the Hedgehog for the Sega Mega Drive/Genesis. He attempted to find the powerful Chaos Emeralds by conquering South Island and turning its animals into robots. Launching a full-scale assault, Robotnik was able to seize control over countless cities, factories, and lands, and transformed them into his image and polluted the very environment with his fortresses. Robotnik ordered his vast army to search for the Chaos Emeralds and build weapons of mass destruction so that his dominance would never be challenged. Luckily, Sonic the Hedgehog sped to the rescue, defeated Robotnik, saved the animals from roboticization, and retrieved the Chaos Emeralds. Thus the island was restored to its former, peaceful state.

Sonic the Hedgehog 2

In the 1992 sequel Sonic the Hedgehog 2 for the Sega Mega Drive, the notorious Robotnik created the Death Egg, a huge, orbital space station during another attempt at world domination. He attacked West Side Island, turning its animals into robots and searching for all seven Chaos Emeralds. He was intercepted by Sonic and his sidekick Miles "Tails" Prower, who saved the animals and retrieved the Chaos Emeralds before the evil scientist. Sonic infiltrated the Death Egg, sending the Death Egg crashing back to Earth and defeating Robotnik once more.

Sonic the Hedgehog CD

In Sonic the Hedgehog CD Robotnik appears once again as the main antagonist. In this game, he invaded Little Planet to find the Time Stones, which would let him control time, where he created a robot army of Badniks using the seeds of Little Planet. He also builds his greatest robot, Metal Sonic, as a means of finally defeating Sonic. He is defeated in the end by Sonic.

SegaSonic the Hedgehog

In SegaSonic the Hedgehog Robotnik captured Sonic, Mighty and Ray and imprisoned them on Eggman Island where he planned to execute them. Though Sonic, Mighty and Ray broke out of their cell, Robotnik blew them to the other side of his island. From there, Robotnik remained in his control tower where he tried to stop the trio's advances. When Sonic, Mighty and Ray got to him however, Robotnik triggered the tower to self-destruct within twenty seconds. Though Robotnik got away, his last plan failed as Sonic, Mighty and Ray escaped in time.

Sonic the Hedgehog 3 & Knuckles

In Sonic the Hedgehog 3 and its expansion Sonic & Knuckles (both released in 1994), Robotnik managed to land the Death Egg on the legendary Floating Island and tricked the island’s guardian, Knuckles the Echidna into thinking Sonic and Tails are villains after the Chaos Emeralds, knowing that Sonic will not be far behind to finish his old nemesis once and for all. In the Japanese manual, Dr. Eggman states that he is a noble scientist who seeks to use his scientific knowledge to better the world with the use of his space station, the Death Egg. He claims that Sonic stole the seven Chaos Emeralds from the land and used them to destroy his scientific achievements for his own ends. However, Robotnik was truly planning on deceiving Knuckles once he served his usefulness and take off with the Chaos Emeralds once the Death Egg was repaired.

Knuckles believes in Robotnik's deception and steals the Chaos Emeralds from Sonic when he first arrives, placing them in strategic locations to be given to Robotnik later, and hinders the hedgehog throughout his journey. Robotnik, in the meantime, constructs fortresses and strongholds throughout the island and builds up his army again with the use of the island's animals. When Sonic and Tails arrive on the island, Robotnik launches a full scale assault that destroys a large portion of the island's jungles and begins his battles with Sonic anew.

Through several more battles, Robotnik is again defeated again when Sonic and Tails rush to the Launch Base Zone and prevents the Death Egg from relaunching. When the chase finally takes Robotnik to Hidden Palace, he confirms the presence of the massive and powerful Master Emerald - which Knuckles protects with his life. He steals it during a scuffle with Knuckles, and uses it to get the Death Egg into space once again. With help from the newly-allied Knuckles, Sonic and Tails are able to chase the madman into space. During their climatic battle, the Death Egg is completely crumbled. Robotnik makes one last chance to escape with the Master Emerald, but Sonic transforms into Hyper Sonic with the Super Emeralds (Master Emerald-powered Chaos Emeralds), and his ambition is thwarted once again. The Master Emerald is returned to Knuckles, and the Floating Island regains its namesake.

Sonic the Hedgehog 4

Dr. Eggman appeared in the episodic Sonic the Hedgehog 4, having survived the loss of the Master Emerald. In Episode I, he merely captured forest animals to power his Badniks and redesigned selected inventions to be trickier than ever for Sonic to handle. His master plan comes together a few months later in Episode II - he resurrected Metal Sonic, who was defeated during the events of Sonic the Hedgehog CD and once again set his eyes on the mystical Little Planet as it makes its annual return to Earth. Sonic hears that Eggman is back, and reunites with Tails to stop him together. Meanwhile, Metal Sonic searches for the heroes and sees them fly away in the Tornado and follows them using Tails' rocket. Towards the end of the game, Sonic and Tails find that the Little Planet has sustained in a remarkable sphere known as the Death Egg mk.II Zone. Fortunately, Sonic and Tails once again beat Metal Sonic at his own game, and the heart of the base was destroyed, deactivating the space station as it harmlessly floats in space.

Sonic Adventure

After these devastating defeats at Sonic's hands, Robotnik's power was diminished a great deal, his forces were largely destroyed, and the villain was no closer to achieving his goal of world domination. Desperate to find alternative means to resume his plans and dominate everything, Dr. Robotnik, at some time prior to the events of Sonic Adventure, had set up shop in the Mystic Ruins. It was here that he discovered the ancient ruined temple left behind by the echidna race and the stone tablets describing the ancient 'god of destruction', a being known to the echidnas as Chaos.

After studying the tablets, Dr. Robotnik learned that Chaos still existed within the Master Emerald, located on Angel Island; the doctor had found the perfect means to conquer the world that didn't rely solely on his machinery. He took his new airborne battleship, the Egg Carrier, to the island in hopes of releasing Chaos from his prison. A swift long-range attack from the Carrier shattered the Master Emerald to pieces and thus released the liquid creature, as well as the spirit of Tikal, a member of the echidnas (though Robotnik was apparently unaware of her existence).

Having released Chaos, Robotnik expected the creature to aid him in his goal of world domination. In order to strengthen the creature, Robotnik immediately began seeking the Chaos Emeralds which he would allow Chaos to consume, thereby becoming more powerful. The first Chaos Emerald was taken from Tails, who had accidentally found it while testing a new plane. The second Emerald Robotnik stole from Sonic (who had won it in Casinopolis) by ambushing him outside the casino in Station Square. Robotnik continued to observe the activities of Sonic and Tails who were frantically trying to gather the Emeralds to prevent him from empowering Chaos, and also managed to fool Knuckles (again) into thinking that they were trying to interfere with his mission to collect the Master Emerald shards (Knuckles initially mistook Robotnik's Chaos Emerald for a Master Emerald shard, which Robotnik promptly used to his advantage). Sonic and Knuckles ran into each other in the Mystic Ruins where Knuckles - believing Sonic to be carrying Master Emerald pieces - attacked Sonic and Tails. Sonic and Tails dropped the Chaos Emeralds they had collected after colliding with Knuckles, and Dr. Robotnik was there waiting for them. He took both Emeralds and fed them to Chaos, who transformed into his fourth phase.

The doctor obtained two more Chaos Emeralds by sending his E-100 robots to hunt down Froggy who had swallowed an Emerald (and also Chaos's tail) and by capturing Amy Rose and her little Flicky friend (which kept a Chaos Emerald inside its locket). With six of the gems in his possession and all his minions assembled on the Egg Carrier, Robotnik nearly raised Chaos to perfect level. However, due to the efforts of Sonic, Knuckles and Big the Cat (and to his own bungling by using freezing weapons) Robotnik lost the Emeralds when Chaos was apparently destroyed, still no match for Sonic despite having six Emeralds powering him.

The Egg Carrier was heavily damaged by the fighting and crashed just off the coast of Station Square. Having lost his ship and Chaos, Dr. Robotnik resorted to launching a nuclear missile in order to destroy Station Square. The missile failed to detonate on impact, and was disarmed completely by Tails. In anger, Robotnik attacked Tails in his Egg Walker machine. Tails managed to defeat him, however, and the doctor retreated to his Final Egg base in the Mystic Ruins where he would regroup and begin concocting new ways to destroy Station Square.

As he returned to his base, Robotnik was pursued by Sonic (who had landed in the jungle after attacking Robotnik as he fled the falling Egg Carrier). Robotnik engaged in one final showdown with Sonic in his base, using his newest mecha - the Egg Viper. This failed to defeat Sonic also and was destroyed, and Robotnik's base was leveled.

Retreating through the jungle, Robotnik discovered Chaos had survived his battle on the Egg Carrier. Chaos had gone rogue and attacked Robotnik, who fled toward Angel Island to seek help from Knuckles. Chaos followed him there and found six of the Chaos Emeralds (Knuckles had retrieved them after beating Chaos on the Egg Carrier), taking them all and knocking out both Knuckles and Robotnik. Sonic and Tails arrived shortly after to investigate why Angel Island had not yet ascended back into the sky, and found Knuckles and the doctor unconscious. When he recovered, Robotnik vowed to take revenge on Chaos and set off back to his ruined base, where a back-up Egg Carrier was docked.

When Chaos became Perfect Chaos after consuming the last Emerald, the monster traveled to Station Square and flooded the city, leaving it in ruins. Robotnik attacked Chaos in the Egg Carrier 2 but the attack had no effect, and with one blast, Perfect Chaos managed to destroy Robotnik's ship. The doctor was sent hurtling off into the clouds screaming, only turning up again just in time to witness Sonic's victory against Chaos, granting him silent acknowledgment before flying away in his Egg Mobile.

Sonic Adventure 2

In Sonic Adventure 2, Dr. Eggman discovered the existence of Project Shadow by accidentally coming across the long-forgotten diary of his grandfather, Gerald Robotnik. In the diary, the professor spoke of a classified military research project that was shut down because the United Federation government feared its misuse. When he accidentally found his grandfather's diary, Eager to see just what his childhood hero had produced, Eggman found that the weapon was stored away on Prison Island, a military compound controlled by G.U.N. He was unaware that he was drawn into an adventure that would show him that his grandfather was perhaps not as innocent as he had thought.

Dr. Eggman attacked Prison Island and broke into the underground base with his new Eggwalker. Happening upon the cryogenic vault where Prof. Gerald's weapon was sealed, Eggman used his grandfather's password: MARIA, the name of Gerald's granddaughter and Eggman's late cousin, then inserted a Chaos Emerald into the control console (where he got the Emerald is unknown). The vault opened, releasing the ultimate life-form: Shadow the Hedgehog.

Eggman mistook Shadow for Sonic at first glance, but Shadow, in gratitude for being released, offered to grant Eggman one wish. Their meeting was interrupted by one of G.U.N.'s Big Foot mechas, which Shadow quickly engaged and easily destroyed. Shadow then fled Prison Island, telling Eggman to bring him more Chaos Emeralds and that he would be waiting aboard the Space Colony ARK.

Eggman headed back to his pyramid base and encountered Rouge the Bat and Knuckles the Echidna along the way, who were fighting over the Master Emerald. Eggman attempted to steal it, but Knuckles shattered it to pieces to prevent its theft. Not really needing the Master Emerald at that time, Eggman returned to his base and caught up on the news. A newsflash announcing the theft of a Chaos Emerald from Central City's federal reserve bank caught the doctor's attention, and although the media and public had identified the suspect as Sonic, Eggman knew it could only be Shadow.

Using his base's space transporter, Dr. Eggman beamed himself to the Space Colony ARK to meet with Shadow. There, Shadow revealed the Eclipse Cannon, a weapon of mass destruction capable of destroying a planet or piercing a star. The cannon required the seven Chaos Emeralds to meet its immense power demands, and two had already been installed. Rouge the Bat - who had boarded the ARK by sneaking into Eggman's pyramid and accessing his transporter - had provided a third emerald for the Eclipse Cannon. Although Eggman was suspicious of her motives, she had provided another emerald and was offering to help him obtain the others. Eggman agreed to let Rouge join him and Shadow in their hunt.

Three more Chaos Emeralds were discovered on Prison Island, locked away in G.U.N.'s high-security vault. Dr. Eggman organized a strategy that would allow him and his cohorts to obtain them. His part in the plan was to divert G.U.N.'s forces so that Rouge could enter the vaults unnoticed and Shadow could plant high explosives in the armory. When the trio made their move, they were interrupted by the untimely arrival of Amy Rose, who had mistaken Shadow for Sonic. Eggman moved in to try and deal with Amy but was stopped by Tails and his new Cyclone walker. Running on a strict timetable, Eggman let Tails and Amy leave alive and made his escape, although not before making clear that the next time they encounter each other, he will make sure to take them out.

He then reported in after Shadow set the explosives and informed them that, thanks to an unexpected delay on Eggman's end, they have no other option but to set the detonation timer to five minutes to make up for the wasted time, with Rouge remarking that five minutes was all she needed to recover the Chaos Emeralds stored in the vault. He also informed Rouge to make sure she gets the emeralds before GUN found her. Eventually, after Shadow took longer than expected to evacuate, Eggman called in and demanded that Shadow escape immediately and hurriedly before he is caught in the destruction of the island. As Shadow had fought Sonic (who had just escaped from his cell) to a stalemate when Eggman called in, this consequentially resulted in Sonic learning of the island's impending doom and inadvertently saved him. The mission was a success despite certain delays, including Shadow having to save Rouge via Chaos Control when she was pinned down at the vault, and the group succeeded in stealing the Chaos Emeralds and destroying the G.U.N. base. With six Chaos Emeralds now powering the Eclipse Cannon, Dr. Eggman announced to the world that the Eggman Empire would arise and dominate the Earth. To prove his power, Eggman pointed the Eclipse Cannon at the moon and fired, blowing it in half. Eggman then delivered his ultimatum to the President of the United Federation: the UF had 24 hours to surrender or Eggman would destroy the entire country. While delivering his ultimatum, Sonic intervened and discovered where Eggman was hiding.

When Sonic and his friends attacked Dr. Eggman's pyramid, the doctor unleashed his mighty Egg Golem robot to destroy Sonic. A battle ensued and Sonic damaged a restraining mechanism on the giant's head, causing it to malfunction and attack Eggman. Eggman was forced to defend himself and destroy the Egg Golem, giving Sonic's gang the time they needed to hijack the doctor's space shuttle. Eggman later returned to the ARK after detecting two Chaos Emerald signatures, believing that Sonic must have a decoy as well as the real one. When he returned to the colony, Eggman took Amy hostage and held her at gunpoint, demanding that Sonic and Tails meet him in the ARK's main laboratory. When they arrived, Eggman ordered Sonic to place the Chaos Emerald in the center of the room. Believing it to be the fake emerald (a belief that was also unwittingly confirmed by Tails when asking him how he deduced it), Eggman then sprung his trap and sealed Sonic inside a containment capsule. The capsule was ejected into space where it exploded, seemingly killing Sonic instantly.

With his arch-rival out of the way, Eggman turned his attention to Tails and the two battled each other in their walkers. Eggman somehow managed to come out of the fight with the real Chaos Emerald and installed it into the Eclipse Cannon, although he later reported to Shadow that someone (Sonic) was making his way to the Eclipse cannon. As he laughed in triumph, danger signs appeared on every monitor on the colony, followed by an image of the late Gerald Robotnik. A message left behind by the professor stated that the world had sentenced him to death, and that he would have his revenge by destroying the Earth. A program within the colony's main computer had been activated which would destabilize the ARK's orbit and send it crashing into the planet, wiping out all life.

Eggman convened with the heroes (and was visibly annoyed to see that Sonic was still alive) and showed them Gerald's diary. He then informed them that the Eclipse Cannon's core had overloaded with Chaos energy and the collision would obliterate the entire planet. The doctor was the one who suggested that they all work together to try and neutralize the Chaos Emeralds and stop the ARK's collision. Of course, this was no doubt due to the fact that Eggman couldn't take over the world if there's no world. With Eggman monitoring the ARK's layout and guiding the others down their respective paths, he, Sonic and the others managed to stop the ARK and save the world from certain doom.

Sonic Heroes

Eggman heroes

Dr. Eggman at his Egg Mobile from Sonic Heroes.

In Sonic Heroes, Dr. Eggman constructs a massive fleet of battleships called the Egg Fleet, and at the heart of this fleet is a flagship even larger than the Egg Carrier. He planned to use this fleet to conquer the world in 3 days, but was locked away in his own flagship by Metal Sonic, who impersonated him and took command of his fleet. Dr. Eggman then enlisted the assistance of Team Chaotix in order to break free, communicating to them by walkie-talkie, giving them their objective for the respective level. However, he once nearly gave away his true identity when Vector, in reference to Metal Sonic disguised as Dr. Eggman, referred to him as a "mustachioed moron." By the time he was freed, Metal Sonic had transformed into Metal Madness. Dr. Eggman assessed that they would need the power of the seven Chaos Emeralds to defeat him (which Team Sonic, Team Dark, Team Rose, and Team Chaotix coincidentally had possession of). After Metal Sonic was defeated, Dr. Eggman tried to sneak away from the Chaotix without paying and was seen being chased by them. It is unknown if they got their money or not.

Shadow the Hedgehog

During Black Doom's invasion of Earth, Eggman initially observed the fighting taking place between the aliens and G.U.N. Realizing that the conflict would surely result in total destruction and thus leave nothing left for Eggman to conquer, the doctor mobilized his army and launched his fleet to destroy the Black Arms. Eggman found himself under attack from all sides; G.U.N., the Black Arms and Sonic and his friends were all interfering with his operations amongst fighting each other as well.

Eggman saw a potential trump card in Shadow and hoped to manipulate the amnesiac hedgehog into assisting him. Ultimately, the doctor's plan failed, and he was forced to confront Shadow himself. He attempted to further confuse Shadow by telling him that he had no past and that he was one of the doctor's new line of combat androids built in the original Shadow's image. He later attempted to convince Shadow not to supply the Chaos Emeralds to Black Doom, alongside Knuckles, Sonic, Rouge, Tails, and Amy, although he ultimately failed, and was left to be consumed by the Death Leeches after inhaling specialized gasses that were emitted by the Black Comet when it was warped to Earth, although he and the others later escaped as Shadow confronted Black Doom's true form Devil Doom. He also heard Gerald's final message to Shadow regarding the imminent invasion of the Black Arms fifty years later, and deduced that his grandfather's plan involved the Eclipse Cannon. It was only after Shadow had learned the truth about his past from Black Doom that Eggman admitted that he was lying; he had, in fact, recovered Shadow after Sonic Adventure 2 and had kept him alive as a test subject. In the end, Eggman was chased by an irritated Knuckles, who thinks that he's going to steal the Chaos Emeralds and the Master Emerald again.

Sonic the Hedgehog (2006)


Doctor Eggman appears in Sonic the Hedgehog (2006) as the main antagonist of Sonic's story, a minor villain in Shadow's story, and a major villain in Silver's story. Here, Eggman has been redesigned with a more realistic appearance. The comical side of his personality is also subdued a bit to bring out his more villainous side. In this game, Eggman invades Soleanna and attempts to kidnap Princess Elise during the Festival of the Sun's opening ceremony in order to release the Flames of Disaster (aka Iblis), since Iblis was sealed away inside Elise's soul. He intends to use the Flames of Disaster in order to rule over time. During Sonic's story he repeatedly captures Elise, only to have her rescued by Sonic. At the end of Sonic's story, when the Egg Carrier is beginning to crash, he battles Sonic in the Egg Wyvern. Sonic defeats Eggman, causing him to go flying off into the sky as the ship crashes.

In Shadow's story, Eggman serves both as a villain and an ally. Before the events of the game, he had somehow gotten a hold of the Scepter of Darkness which contained Mephiles the Dark. Rouge the Bat had stolen it from him and Shadow was sent to rescue her. Eggman followed them to Kingdom Valley, demanding them to return the scepter, which ended in a struggle that caused the scepter to shatter. Eggman was forced to retreat, although most of his robots, due to electromagnetic pulses from the remains of the scepter, were unable to escape despite his ordering for them to retreat, and were eventually knocked down by Mephiles' spirit shortly before the latter possessed Shadow's shadow. He later appears when Shadow breaks into his personal train in order to learn the truth of the Solaris Project. Eggman makes a deal with Shadow that he will tell him about the project if he captures Mephiles and brings him to him.

Though he only physically appeared twice in Silver's story, Eggman was a key villain as his actions, as suspected by Silver, would've have ultimately unleash Iblis, thus turning the world and its future into an apocalyptic state. Ironically, both times he appeared had him abducting Elise and escaping before Silver ended up killing Sonic, thus ensuring that Iblis did not end up released via Elisa shedding tears.

Eggman does not appear again until the final story, where he and the rest of Sonic's friends (and Elise) have been sucked into the space rift that was created during the birth of Solaris, and states that Solaris can't be defeated since it exists in the past, present and future. Upon discovering that Sonic could be brought back to life with the power of the Chaos Emeralds, he aids the others by locating the Emeralds using a radar inside his glasses.

Sonic Rush series

Sonic Rush

In Sonic Rush, Eggman joins forces with his doppelganger, Eggman Nega, to steal all of the Sol Emeralds and Chaos Emeralds to form a world called Eggmanland. Unfortunately for them, Nega's nemesis, Blaze, came from the Sol Dimension and teamed up with Sonic the Hedgehog to beat them.

Sonic Rush Adventure

In Sonic Rush Adventure, Eggman joins forces with Eggman Nega once again, this time they make a crew of robotic pirates that stole Blaze's Jeweled Scepter along with the Chaos Emeralds and the Sol Emeralds, to form the Eggmanland again. However, the pirates were defeated by Sonic and Blaze and they reclaim the Jeweled Scepter. Although, it didn't take long for both doctors to steal the Scepter again and use it to power up their Egg Wizard. They attempted to use it to unlock the "Power of the Stars", but the duo was defeated by Super Sonic and Burning Blaze. Although their mech, the Egg Wizard, was completely destroyed, Eggman was able to escape as usual.

Sonic Unleashed

Eggman is the main antagonist in Sonic Unleashed. Eggman uses the power of Super Sonic to break the planet into pieces and awaken Dark Gaia and use its power to create Eggmanland. He also accidentally turns Sonic into a werehog by awakening Dark Gaia too early, but he quickly sent him falling down to the Earth with the drained Chaos Emeralds. This proved to be a fatal mistake when Sonic survived and restored the Emeralds' power to bring the pieces of the planet back together and beat his Egg Beetle, Egg Devil Ray and the Egg Lancer. However, the doctor managed to gather Dark Gaia's power before Sonic brought every piece of the world back together, and used it to power the Egg Dragoon and attack Sonic. Even when powered by Dark Gaia, Sonic proved victorious and defeated Eggman. However, Dark Gaia then formed in front of them, and Eggman ordered it to attack Sonic. However, in a similar fashion to Chaos, Dark Gaia sent Dr. Eggman flying before fighting Sonic and Gaia Colossus. Sonic Unleashed marks the first time that Dr. Eggman actually realized Eggmanland, but later got destroyed by Sonic. Eggman himself survived Dark Gaia's attack and chased his sneering robot assistant Orbot into the sunrise.

Sonic Riders Series

Sonic Riders

In Sonic Riders, Dr. Eggman opens a stadium called the "EX World Grand Prix" in which Sonic, Tails, Knuckles, Amy Rose and the Babylon Rogues compete against each other. Whoever wins will get Chaos Emeralds, and to enter, that will cost one Chaos Emerald.

To get the Babylon Rogues to the race, Eggman had to hire them, he also told them that if they win, they will get a chance to get all seven Chaos Emeralds, since Jet wanted to awaken Babylon Garden with the power of all seven Chaos Emeralds they has accepted it. When Jet won against Sonic by cheating, Jet was able to use all of the Chaos Emeralds' power so that the Control Box can awaken Babylon. But apparently after awakening Babylon Eggman stole the Control Box for his own purpose. Thanks to Sonic, Eggman was defeated.

When the Babylon Rogues reached a secret area, by using the Control Box, Eggman claims that he was after the treasure all along. When Sonic and Jet open the treasure box, Eggman begs them to hand over the treasure, Sonic and Jet cleverly grin at each other and gave him the treasure, which was a magic carpet, Eggman was disappointed since he thought that the treasure was not valuable, so he passes out. He can be unlocked to play as by completing the Babylon story line.

Sonic Riders: Zero Gravity

In Sonic Riders: Zero Gravity, Eggman uses robots from MeteorTech to collect the Ark of the Cosmos, something which Jet was after. But unfortunately for Eggman, the robots actually have their own program, to go amok after the Ark of the Cosmos. Sonic and Jet find Eggman guilty but Eggman claims that their craze after the Ark of the Cosmos is not his fault. In the end of the game, when Eggman finds out that the world is doomed because of Master Core: ABIS, a formation of MeteoTech, Eggman says "The world is doomed!" and escapes.

Sonic Free Riders

Eggman is the king

Eggman disguised as a king.

In Sonic Free Riders, he held the World Grand Prix again but this time besides Team Heroes vs. Babylon Rogues, there are two other teams like Team Dark and Team Rose. He is dressed to disguise as a king (named "King Doc of Toreggmania") in this game. When he decides to drop the disguise, he reveals that he's been copying everyone's data to make himself the fastest Extreme Gear racer (and possibly for other purposes). But the data turns out be useless as it is revealed that Metal Sonic has stolen the data for himself and has been giving Eggman false data, much to to the doctor's anger.

Sonic Rivals series

Sonic Rivals

Doctor Eggman appears in Sonic Rivals released for the PSP who actually plays a heroic role in contrast to his evil deeds in almost every other occasion. Throughout the game, it is revealed that Eggman Nega is masquerading as the doctor himself and captured the real Doctor Eggman into a card by Nega's special camera. By the aid of Shadow and a new hedgehog character, Silver, the doctor is rescued and helps to escort the two hedgehogs to Eggman Nega's base at outer space in order to stop the mad scientist from turning the entire world into a card.

Sonic Rivals 2

In Sonic Rivals 2, he makes Shadow and Metal Sonic team up for his attendances. In the game, Eggman seems to know something about Ifrit and tells Shadow that the Ifrit may destroy the world by eating Chao. As Shadow is aware of it, he tries not to tell anyone about it.

Sonic and Tails find one of Eggman's pages on Ifrit and shows the pages to Eggman to explain, Eggman who was shocked to see how did they find these pages, fails to explain and runs off.

Sonic Colors


Dr. Eggman's brochure about his amusement park.

Dr. Eggman appears once again as the main villain of Sonic Colors. In the game he creates Dr. Eggman's Incredible Interstellar Amusement Park, which is an amusement park that has five planets chained together to the main park. He had announced that he made the park for people to enjoy and to show a remorse of his past deeds. Sonic, however, doesn't believe this, and goes to the amusement park. Sonic is right, Dr. Eggman is up to an evil scheme. He is capturing Wisps so that he can take their Hyper-go-on energy, and turn it into negative energy that powers a Mind Control Ray in order to take over the universe.

Eggman pretends that he has he has turned over a new leaf, but that couldn't fool Sonic one bit. He send out many robots to destroy Sonic, but in the end they just get trashed by the hedgehog. He has used 5 generators to link all planets together; however, that was the only thing Sonic knew, so he thought that releasing all of the chained planets would end Eggman's scheme. When Eggman tries to fire the cannon, the energy backfires due to Rotatatron's robotic arm, which was stuck inside cannon. Eggman challenged Sonic to beat him as he was using the negative hyper-go-on energy to power a giant robot called the Nega-Wisp Armor. Sonic manages to beat him and Eggman ends up getting sucked into the black hole created when the negative energy backfired.

After the credits, Eggman had survived the black hole and is seen helplessly stranded in space with Orbot and Cubot, Cubot was celebrating that he got his voice back and kept on talking. Eggman wished for a moment of silence, but Cubot would not stop talking.

Sonic Generations


Modern and Classic Dr. Eggman in Sonic Generations.

In a surprise twist, Dr. Eggman of the present, named Modern Eggman, and his past self Classic Eggman are the main antagonists in Sonic Generations. After the events of Sonic Colors, Eggman found a strange creation in space that could erase time and space, and decided to use it to erase his past defeats. He left Orbot and Cubot stranded in space and went with the creation to travel in time. However, he needed another genius to control this creation and, during the game's story, he rescue his past self after the Death Egg battle. Later, Modern Eggman tried to destroy Sonic himself using a new Egg Dragoon prototype in the Sonic Unleashed timeline, but he failed and got away using the creation.

At the beginning of the game, this creation, named Time Eater, travels to Green Hill, causing a white fade while Classic Sonic looks on in wonder. Then Time Eater travels to the present to ruin Modern Sonic's birthday party by kidnapping all of Sonic's friends and sending them to different time holes to bait his traps. Sonic could not stop him and finds himself in the White Space

Near the end of the game, both Sonics and both Tails find out about the Time Eater's true origin when the doctors reveal themselves and their plan, intending to dispose Sonic from time (although Classic Eggman ended up disturbed that he might become crazy when witnessing Modern Eggman breaking down into hysterical laughter). Early in the battle both Sonics are unable to stop the doctors' creation, but after transforming into Super Sonics and enduring the intense battle, both doctors are defeated once again and all the characters return to their world and time.

After the end credits it is shown that both Eggman got stuck in white limbo and are unable to get out. After arguing whether or not they would ever win, Classic Eggman thought that maybe he would instead pursue his "teaching degree" after these events, to which Modern Eggman agreed as he enjoyed telling people what to do. It's unknown how did Modern Eggman to escape from the white space and whatever happened to Classic Eggman after the events of the game.

Sonic Lost World

SLW JND Badniks Strike Back!

Eggman being cornered by his own Badniks thanks to the Deadly Six.

Dr. Eggman appears in Sonic Lost World first as the main antagonist, then as a deuteragonist and finally winds up reclaiming his role as main antagonist. Eggman is first seen carrying an animal capsule while being pursued Sonic and Tails on their Tornado. After distracting the brotherly duo by cruelly dropping the capsule, Eggman shoots down the Tornado with a ray gun. By the time Sonic and Tails confront Eggman again, they discover that he, at some point, had discovered a group of six menacing Zeti known as the Deadly Six, and that he had decided to use them in an attempt to rule the world.

Unfortunately for the doctor, Sonic knocks away the Cacophonic Conch that Eggman was using to control the villains while at Desert Ruins; as a result, the Deadly Six rise up against their master, taking control of his badniks in the process and decide to destroy the world themselves with the Extractor, a device Eggman had built for the purpose of absorbing the planet's energy so as to put it towards his plans for world domination. After the attack, Eggman blames Sonic for the betrayal of the Deadly Six, but soon decides to join forces with Sonic, who reluctantly agreed to since the world was in danger. During the time that Eggman was allied with Sonic, he frequently got into arguments with Tails, who - in contrast to his demeanor towards the doctor in Sonic Colors - does not trust him. In spite of this, Eggman winds up saving Tails' life at one point when Cubot - then fused with one of the Deadly Six's badniks - attacked him.

When Sonic, Eggman, Orbot and Cubot arrive at Lava Mountain, Zomom and Zazz start attacking them with large rocks, destroying the bridge the heroes were on and seemingly forcing Eggman to sacrifice his life to save his arch-enemisis. However, after Sonic defeats the Deadly Six, Eggman reveals that he had survived his fall by utilizing a jetpack and had spent the time that Sonic was fighting the Deadly Six to build a mech powered by the energy the Extractor had absorbed. Even with his mech's enormous powers, however, Eggman is soundly defeated by Sonic while Tails manages to restore the planet's energy. Eggman tries to flee using the jetpack he had used earlier, but Sonic had removed one of its exhaust pipes while Eggman was unconscious, sending the doctor plummeting back to Earth. The ending scene of the game reveals that Eggman survived his fall but got stuck in a patch of soft dirt: Orbot and Cubot - now fused into one body - manage to rescue the doctor, but not before a rabbit eats half of his moustache: the duo mention this by mistake and soon flee from a very angry Eggman.

Other Game Appearances

Besides the main game series, Dr. Eggman has appeared in several other games than the 2D and 3D platform games as well, such as Sonic Drift, Sonic Drift 2, SegaSonic Cosmo Fighter etc., or appearing as a cameo such as in Super Smash Bros. Brawl.

Sonic and the Secret Rings

While the actual Dr. Eggman does not appear in Sonic and the Secret Rings, King Shahryar of Persia greatly resembles him. First seen after the Sand Oasis stage, he has recently been attacked by an unknown entity and he mistakes Sonic for the attacker. A bird-like spirit kidnaps him and attempts to drop him off a cliff. Shahryar tells Sonic to save him. Sonic, unsure of what to do, stands still until King Shahryar drops and catches his collar by the tip of his shoe.

Dr. Robotnik's profile in Sonic Jam.

Eggman is a short-tempered, raucous, pompous, cruel evil genius who is constantly planning to take over the world. Despite his intelligence, Dr. Eggman is immature, throwing temper tantrums when Sonic manages to wreck into his plans.

Eggman seems to overlook crucial details in his plans, such as in the opening sequence of Sonic's story in the 2006 video game when he orders his robots to fire on Sonic while he is escaping with Princess Elise, failing to realize that they could possibly injure or kill Elise if they land a direct hit on Sonic and overlooking Dark Gaia's immature release in Sonic Unleashed. An example of his immaturity is in the ending of Sonic Unleashed, when Orbot begins to insult him over his constant failures and calls him a loser; Eggman screams "Oh, shut up!!", attempts to kick him only to comically fail, and then chases him through the desert.

Eggman is also very arrogant and narcissistic to himself; possessing a psychotic belief of self entitlement of controlling the world and beyond and constructs countless technological wonders in his own image to fuel his massive ego. His main plans is to create the ultimate utopia, the Eggman Empire, are always in full swing, and he does not care where to start it -- in the end, he plans for it to encompass all of Earth and even beyond. His abominable laughter and maniacal declarations contrast his self-professed softer side as a romanticist, feminist, and gentleman. Despite his and Sonic's constant feud, he has secretly developed a begrudging respect for the hedgehog. Although Eggman is a villain, he helps Sonic and co. when the world is at stake - though the reason is always because he knows there would be nothing left for him to conquer if the planet was destroyed.

File:Eggman profile.png
Eggman has never shown a willingness to do good or help others without it serving his own ends in some shape or form. While displaying a comical disposition later on in the series, he is quite clearly a cruel minded and brutal man who will use any opportunity presented to him to fuel his self-serving desires, even if that means exploiting worldwide catastrophes to obtain power and dominance. From abducting and transforming animals into robot armies, to leading large scale attacks on a terrorist level, Eggman's numerous crimes and exploits continuously transition into more destructive ramifications. He never acknowledges the results of his actions such as the pollution from his fortresses and strongholds that poison the surrounding environments or the ruins that are left from his own attacks on various cities and lands. His exploits have led to numerous tragic events, such as Chaos flooding and utterly destroying all of Station Square and Dark Gaia nearly consuming the whole planet, as well as leaving numerous areas, lands, and even planets in ruins and threatened the welfare of time, space, and the universe itself.

However, despite his desire for world domination, Eggman does have a human side, and does not appreciate senseless destruction, tormenting and killing from other individuals and forces who are beyond his control. In Shadow the Hedgehog, he is shown to be disgusted and shocked at the thought that his own grandfather would sacrifice his own people for the sake of research and aid the Black Arms. This demonstrates that even if Eggman does not mind causing chaos and destruction, he ultimately knows that there is a line that others should not cross and was afraid his grandfather did so through betraying humanity and aiding a species that wanted to eliminate the human race. This shows that the doctor has some form of loyalty to the human race and could not fathom the idea of betraying his own species to that of a vicious and demonic alien empire, despite some of their actions mirroring his own in terms of the scope of their plans and the destructive ramifications of their actions.

While this seems contradictory towards Eggman's previous exploits of joining forces with other creatures bent on destruction, it seems that he still wishes to paint his grandfather in a positive light as he was his hero in his childhood. This more humane side to the doctor is shown in full force at the end of Sonic Adventure 2, where he has an honest and genuine conversation with Tails about how much he adored his grandfather, questioning the actions of his fallen idol and wondering if he intended to destroy him as well. Additionally, in Sonic Lost World, he unhesitatingly jumped in to save Tails from being attacked by a Crabmeat-controlled Cubot, and when questioned by Sonic over having rescued one of his worst enemies, Eggman admits that he's "a complicated guy."

Despite this, Eggman seems to have no problem in committing senseless killing and destruction as long as he is the one in control of the forces doing so. It would seem that the doctor is so bent on authority, that he refuses to let other forces destroy his planet unless they are under his complete control. This is shown when Chaos betrays Eggman and floods all of Station Square, an action that Eggman had planned Chaos to do from the very beginning regardless of the beast's betrayal against him, but refused to allow his rampage to continue as Chaos was no longer under his control. Additionally, in Sonic Adventure, he launched a missile deep into the heart of a heavily populated Station Square to utterly destroy it, even if that meant killing himself, as a twisted form of revenge and victory over Sonic after his plans to use Chaos to dominate the planet failed. In Sonic Adventure 2, his desire for destruction appears at its height as he laughs insanely at the Eclipse Cannon's impending firing at the planet, which would have had devastating effects to billions of lives, until his grandfather's true operations were activated. He also admits that had he had the chance to use the space colony ARK to collide with Earth, he would've done so a long time ago, showing admiration towards his grandfather's mad projects, and only decides to prevent them from coming to fruition in order to save his own life as escape was impossible with the colony on its collision course.

In Sonic Unleashed, there is a possibility, realistically speaking, that he murdered millions when reawakening Dark Gaia by splitting the planet itself apart, though the effects of the quake in relation to the earth's populace is never touched upon. In Sonic Lost World, Eggman contemplates destroying one of his own doomsday machines to ultimately destroy the Deadly Six, even if it means taking many innocent lives with them, much to Sonic's disgust. According to his PA announcement in Sonic Colors, his park can be considered a lethal weapon in itself as most of the rides lead to horrifying and agonizing deaths and circumstances should anyone ride them. Lastly, in the beginning of Sonic the Hedgehog (2006), he orders his robots to launch numerous missiles at Sonic with no regard for any that may be caught in the crossfire.

Regardless of how many lives may or may not have been lost to Eggman's various schemes, the evil scientist clearly demonstrates a complete disregard for all life, even his own on occasions, as well his own creations, and will go to any means necessary as long as his goals of destroying Sonic and his friends, conquering the planet, and establishing his empire are met with full success. With the means for Eggman's plans to succeed often resulting in massive amounts of chaos and destruction, the success of his schemes would also result in a world slowly dying away from Eggman's ruthless and tyrannical rule. The various, dark futures within Sonic CD provide a glimpse of the horror that would be a world under Eggman's control; twisted steel, pollution, and ruin, to the point that even Eggman's own creations are in pitable states, illustrating that once Eggman has seized control of the world, he will become a ruthless tyrant who will exploit all of the planet's resources to the point that they are polluted or depleted as even his own creations suffer. This could imply that once Eggman has conquered the world, there will be little need of his robotic army as he primarily uses them to conquer territory and will be seen as expendable to him and left to rot. This would further be indicative towards how Eggman has previously treated his robots if they failed him, ordering torturous redesigns on his various E-Series robots if they did not complete their missions and even abandoned Orbot and Cubot in the vastness of space without a second's hesitation, though they would later rejoin the doctor sometime later despite this.

Perhaps the most frustrating and deadly aspect about Eggman is his tendency to always escape at the last minute, even as all his creations and machines crumble and blow up around him, ensuring that he will always be back again with another scheme to endanger the planet and beyond. No matter how close Sonic appears to be finally catching the villain and putting him out of commission, the doctor always has an escape plan, which ironically enough, are the only plans he can formulate that Sonic has been known to fail in foiling, making it nearly impossible for both individuals to defeat the other for good, making their battle a never ending one.

One of Eggman's more admirable, if not dangerous, traits is his courage throughout life threatening situations. Despite Eggman's continuous use of machinery to both protect himself and fight his opponents, Eggman shows considerable bravery throughout the entirety of the series and very rarely shows fear, regardless of who or what he is facing. Even in the wake of the Black Arms invasion, Eggman remains very composed when facing the demonic and destructive race and even enters their base of operations, the Black Comet, himself without showing any fear. His persistence to control other creatures bent on mass destruction and approach them to ultimately tame them, including Chaos and Dark Gaia, also illustrate his apparent lack of fear.

Eggman, while sending out his army to do most of his dirty work, has also been known to lead missions personally with himself in the field for both good and noble deeds, though with self serving interests always at the forefront of his mind. His apparent lack of fear during these missions can be owed partially to the fact that Eggman has previously shown a disregard for even his own life on several occasions, as long as his plans come to full fruition. In Sonic Adventure 2, Eggman tells Shadow that he might not survive his battle with Sonic in the space colony ARK and instructs him to finish their plans to use the Eclipse Cannon to dominate the planet and possibly even use the weapon to destroy large portions of it. While the villain has been known to panic when his plans spiral out of control, especially when victory previously seemed assured, he is always able to compose himself long enough to either finish the mission at hand or escape at the last minute.

Ultimately, while not openly violent and ruthless, Eggman is still a highly brutal and amoral villain with an insatiable lust for power, dominance, and, since meeting Sonic, revenge. While still harboring a more humane side and displaying comical undertones, Eggman's ruthless and violent nature can still be seen throughout the series. His uncompromising persistence shared with his appetite for authority and control fuel the conflicts throughout the entire series and guarantee that Sonic will always be needed to stop him.

Powers and Abilities


Dr. Eggman piloting one of his robots.

Eggman's most well known ability is his masterminded plots and schemes which only fail due to Sonic and his friends. He is a remarkable scientist and engineer, as evidenced by the numerous armies of robots and other mechanical inventions he has created. Eggman is an incredibly skilled pilot: able to swoop missiles and lasers in his Egg Mobile with skills rivaled only by Eggman Nega and Tails.

Eggman has considerable physical strength as seen in Sonic Lost World where he was able to shatter a large wall of ice with his bare hands,[3] and in Sonic Riders, Eggman is classified as a Power Type, further implying a high level of strength for Eggman.[4] As seen in some games' endings he is also quite resistant to damage, being catapulted or falling vast distances only to come out scratched up but mostly unharmed.

Despite his physical structure, Eggman is also very athletic; this is seen in many of the 16-bit era games, where there is almost always a point where Sonic chases him and despite of his weight and Sonic's speed, he always manages to outrun his nemesis long enough to reach his next escape vehicle or weapon. This trait of agility is carried on in Mario and Sonic at the Olympic Games and Sega Superstars Tennis. In one cutscene of Sonic Lost World, Eggman is seen to be running at the same speed as Sonic. Although it has been proven, it is unknown if he can consistently outrun Sonic, since he is almost always in his Egg Mobile.

Naming Variations

Sonic1 us manual 02 03

"Dr. Ivo Robotnik" in the North American manual of the original Sonic the Hedgehog.

Although the character was designed as Dr. Eggman in Japan since the original Sonic the Hedgehog, he's instead known as Dr. Robotnik in Western countries. The name Dr. Ivo Robotnik[5] 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'[6] (some drafts of the unpublished Sonic Bible also specify that it should be pronounced "ee-vo", rather than "eye-vo" as it is usually pronounced in English) 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.[7] 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 this, the name "Eggman" can be found in the sequel's Wing Fortress Zone, as well as Sonic Drift 2 and Sonic the Fighters. 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 & Tails 2, and the banners decorating Spring Stadium Zone in the Sega Saturn edition of Sonic 3D: Flickies' Island. It wasn't 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, adding that Sonic was probably the first person to give him the name Eggman (though not maliciously).[8] Since Sonic Adventure, he has mostly been known in America as "Eggman", with the use of the name "Robotnik" becoming rare. However, it should be noted that in the English version of Sonic Adventure, only Sonic, Tails, Knuckles, and Amy explicitly call him Eggman. He now refers to himself as Dr. Eggman in all games and media, although the Robotnik name is still occasionally acknowledged. In Sonic Adventure 2 he calls himself Eggman as does every one else (even though "Robotnik Empire" appears in the background along with "Eggman Empire" during his demonstration of the ARK's Eclipse Cannon and two of his relatives are present in the game, both using Robotnik as their last name). In the flash comic included in some versions of Sonic and the Secret Rings, Sonic once refers to his nemesis as Dr. Ivo "Eggman" Robotnik. In at least the English version of Sonic Chronicles: The Dark Brotherhood, he briefly refers to himself as Dr. Robotnik. A now to his birth name is also found in Sonic Generations when Classic Tails refers to Classic Eggman as Dr. Robotnik, Classic Eggman claims that "nobody calls [him] that anymore". This joke is not present in the Japanese vocal track.


Sonic the Hedgehog

Quotation1 Curse you, Sonic! Not only do you foil my plans, but you foil my speeches as well! I work hard on them! Quotation2
Eggman, after Sonic taunted his amusement park puns.

Eggman has many enemies throughout the series, but his arch-nemesis is none other than Sonic the Hedgehog. Sonic always thwarts the doctor's evil plans for world domination. Despite this, Dr. Eggman has teamed up with Sonic at times mostly whenever the planet is in danger by a greater force, showing that they can somehow go beyond their hatred and get along if the situation calls for it. Two examples being in Sonic Adventure 2 when he helps to stop the ARK from crashing into Earth, and Sonic the Hedgehog (2006) where he aided the heroes in locating the Chaos Emeralds. In addition, in Last Story of Shadow the Hedgehog, shortly after Sonic tells Shadow to give him the Chaos Emeralds instead, Eggman says "Don't give them to Black Doom!", implying that he at that moment was even willing to let Shadow potentially supply the Emeralds to Sonic if it ensured that they didn't go to Black Doom instead. They also form temporary alliances in Sonic Chronicles: The Dark Brotherhood and Sonic Lost World. This could be because he realized the hedgehog's determination was as fierce as his own over the years, and gained a certain respect for his constant adversary.

Sonic seems to tease Eggman a lot. It is thought that Sonic might have given him the nickname "Eggman," due to his body shape being an obvious target for criticism. While Sonic usually treats Eggman with playful disregard, Eggman generally views his enemy as either an annoyance or a threat. It is rare that he will ever taunt Sonic back, unless he holds the proverbial cards. It is an obvious fact that Eggman holds a grudge on Sonic most of the time, but in the Sonic Simulator Missions of Sonic Riders: Zero Gravity, Eggman says, "Now that's the Sonic I know! They don't call you the fastest in the land for nothing."

Eggman, ever prideful, maintains a facade that his concern is only for world domination and not Sonic's death, although there are times when he will directly challenge him. As players approach the end of the games, Eggman refers to Sonic in increasingly threatening ways and places greater priority on stopping him. Eggman has made eliminating Sonic his second goal under world domination. It is also implied that his attempts and failures to defeat Sonic may have driven him somewhat insane, as after revealing his plan to use the Time Eater to rewrite history to ensure he came out on top, the Present Eggman proceeded to laugh maniacally and excessively, causing his past counterpart to become disturbed that he may eventually become as crazy as his present self.

Although part of a different continuity, the early Sonic canon shows Sonic and Robotnik as once being good friends, a side of them that's never seen in the games.

Miles "Tails" Prower

Tails was the only person to have ever been able to match Eggman because they are both mechanical geniuses and was his direct rival over the course of Sonic Adventure 2. After that it seemed as if their rivalry had watered down, possibly because they had to work together. Once again, in Sonic Chronicles: The Dark Brotherhood, they had to work as allies, but this time they shared a mutual respect for each other, because they were both respected geniuses. In Sonic Lost World, Tails is very bitter towards Eggman and often insults him and acts sarcastically, in one cutscene it looks like they almost come to blows, however Sonic steps in. In that same scene, Tails seems upset and even angry because he believes Sonic trusts Eggman to stop the Extractor more than him. Despite this, Eggman saves Tails from Cubot when he attacks Tails because Tails put his head onto a broken Crabmeat, making him "very mean" as Cubot puts it. Later when Tails is captured, Eggman says that they need to make sure that "his sacrifice wasn't for nothing" in a low somber voice. Meaning that even though Tails doesn't trust him, Eggman may at least have some kind of respect or even care for Tails. As of now though, Tails is the second greatest threat to Eggman's desire for world domination (the first being Sonic, of course).

Knuckles the Echidna

The two were once partners, until he tricked Knuckles, then subsequently electrocuted him so that he could snatch the Master Emerald. Ever since, Eggman has become the one person that Knuckles can't trust at all, yet still seems to fall to victim to his plans, especially if Sonic's involved. However, Knuckles has gotten better with this over the years and is more aware of Eggman's tricks. Knuckles is the third greatest threat to Eggman because he helps Sonic and Tails foil his plans.

Doctor Eggman Nega

In the Sonic Rush series, the counterparts become partners to create their own Eggmanland, Sonic has even mistaken Eggman Nega for Dr. Eggman and thought that it was just a silly new disguise. However, in the Sonic Rivals series, Eggman Nega turned Eggman into a card, sparking some animosity.

It is likely that their alliance fell apart at the end of Sonic Rush Adventure when Eggman Nega nearly blew up the earth against Eggman's wishes. It is also revealed in Sonic Rivals that Eggman Nega is not Eggman's dimensional doppelgänger, but his descendant from at least 200 years in the future, though it's never made clear if Eggman himself knows about this fact.

Shadow the Hedgehog

Since Shadow was created by Eggman's grandfather, Eggman was after Shadow because he was stated as the "Ultimate Lifeform" which could help him conquer the world. When he released Shadow from his capsule, he thought that Shadow was Sonic, but then he realized that the hedgehog merely looked like his rival.

In Sonic Adventure 2, everyone was shocked when they realized that Shadow was created to kill everyone on Earth, even Eggman himself. He also ordered Shadow to work for him, steal all seven Chaos Emeralds, and to keep Sonic out of the way so that he wouldn't foil his plans.

But after Sonic Adventure 2, Eggman seems to have a dislike for Shadow and told Shadow not to disturb him in Sonic the Hedgehog (2006). However, he depended on Shadow to eliminate the Black Arms in Shadow the Hedgehog. In the Sonic Rivals series, Eggman turns to Shadow for help in defeating Eggman Nega, although they still appear to be enemies whenever Eggman is the villain.

Orbot & Cubot

Eggman created Orbot to wait on him hand and foot in Sonic Unleashed, but Orbot has gained a personality of his own, much to Eggman's annoyance. The two tend to argue with Orbot winning, therefore, Eggman will do something like smacking him. And at the end of Unleashed, Orbot still continued to insult Eggman and his blunders, until Eggman finally snapped and chased him off into the sunrise.

In Sonic Colors, Eggman is slightly more annoyed with Orbot and, therefore, gives him more work to do. In response, Orbot will act sarcastic and, like in Unleashed, seize any chance to insult him. Orbot's counterpart, Cubot had his voice chip malfunctioned and adapted to cowboy and pirate accents throughout the story, also much to Eggman's annoyance At the end of Colors, Eggman is seen ordering Orbot and Cubot, to push his Egg Mobile after it lost power, while he's safe and comfortable inside although throughout the trip, Cubot was excited to have his regular voice and began talking non-stop which also leaves Eggman exasperated. The official Sonic Colors website and manual also states that while Orbot obeys Eggman faithfully, he doesn't like him very much while Cubot, on the other hand, likes Eggman but tries to get out of doing any work.

In Sonic Generations, it is revealed that Eggman apparently abandoned Orbot and Cubot in space after discovering the Time Eater. However, they returned in Sonic Lost World.

Gerald Robotnik

Eggman and Gerald Robotnik had not been known to interact with each other, although Eggman had immensely respected his grandfather, who likewise acted as the reason why he desired to become a scientist. However, his respect for his grandfather was shaken somewhat after learning of Gerald Robotnik's irrational desire of destroying all life on the planet via a collision course from the Space Colony ARK due to insanity caused by grief from Maria's death. His trust was even further decreased when he learned from Black Doom that his grandfather had sold out the Earth to the Black Arms in exchange for completing Project Shadow, although he regained most of his respect for his grandfather when he learned about Gerald's intention of wiping out the Black Arms with the Eclipse Cannon.





Appearances in Other Media


Adventures of Sonic the Hedgehog

This version of Doctor Robotnik was a dictator who desired to conquer Mobius with the help of his badnik creations, Scratch and Grounder, although he always failed.

Another one of his badniks is named Coconuts. Doctor Robotnik demoted Coconuts to sanitation duties.

Sonic the Hedgehog (animated 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

In the SatAM cartoon, Robotnik's Doomsday Project was heavily foreshadowed during the second season, and series ended with Sonic overthrowing his rule but left on a big cliffhanger.

Sonic the Hedgehog: The Movie

Sonic Underground

Sonic X

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, Decoe and Bocoe, and a messenger robot named Bokkun. By mistake, he and Sonic and co. arrive there, meeting, among others, Christopher Thorndyke. He mainly schemes diabolic plans for world domination but Sonic and his friends frequently stops the doctor 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.

Cultural impact


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.[9]


Over the years, Dr. Eggman has been used in a variety of merchandise, from collectible pins and plushies to specialized notebooks and clocks.

Critical Reception

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".[10] 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",[11] and has also commented that his character is a "pretty clever riff on Teddy Roosevelt" that has added to the attraction of the series.[12] 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.[13] Eggman was also named the 15th most diabolical video game villain of all time by PC World.[14] 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."[15]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 early version of 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.
    • Similarly, in the Archie Comics and in the Fleetway, his original name is "Kintobor" which is backwards for "Robotnik."
    • "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.
  • 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 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 the 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.
  • As said in Abilities, Eggman outruns Sonic in many games, like Sonic and Knuckles.
  • 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 Colors, he kidnaps and drains the energies of the Wisps. In 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.
    • Out of all his plots, Generations is the only one in which the being he is attempting to harness the powers of does not betray him.
