History

Past

In his childhood, Ivo 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 he decided to follow in his grandfather's footsteps and became a scientist, as well as pursuing 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, utterly convinced with his twisted belief that the results of a world conquest orchestrated by him would make the world a better place and benefit all its inhabitants.[13] Using his unmatched genius, Eggman began his plans, spending his entire life on his self-righteous mission.[13]

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.[14]

Sonic the Hedgehog (1991)

Son1 04

First confrontation of Robotnik with Sonic.

In Sonic the Hedgehog, Dr. Robotnik 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 being turned into Badniks, and retrieved the Chaos Emeralds, thus the island was restored to its former, peaceful state.

Sonic the Hedgehog 2

Mega Drive

In Sonic the Hedgehog 2, 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 again.

Game Gear/Master System

In Sonic the Hedgehog 2 (8-bit), Robotnik kidnaps Tails and several of Sonic's animal friends for ransom in an attempt to lure the Chaos Emeralds from Sonic, stating that the only way he can get Tails back is to give him the six Chaos Emeralds, which the blue hedgehog eventually does. Robotnik is eventually defeated when Sonic faces his latest invention at the Crystal Egg Zone, proceeding to save Tails.

Sonic Chaos

Robotnik steals the Chaos Emeralds from South Island, thus destabilizing the island and forcing it to sink into the ocean. Sonic and Tails head out to stop him, which they eventually do, thus resulting in another defeat for Robotnik.

Sonic the Hedgehog CD

Eggman CD ending

Robotnik escapes with a Time Stone.

In Sonic the Hedgehog CD, Dr. 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.

Robotnik also builds his greatest creation yet, Metal Sonic (who kidnaps local inhabitant Amy Rose) as a means of finally defeating Sonic.

Robotnik's plan ultimately fails when he is defeated by his arch-nemesis once again at his base of operations, the Metallic Madness.

SegaSonic the Hedgehog

SSTH Eggman Tower

Doctor Robotnik in Eggman Island

In SegaSonic the Hedgehog, Dr. 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

Knuckles trying to save the Master Emerald

Doctor Robotnik steals the Master Emerald

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 after the Chaos Emeralds, knowing that Sonic will not be far behind to finish off 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 the 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.

After his defeat, Robotnik sends a powerful Eggrobo badnik and Mecha Sonic (who had survived his battle with Sonic back in the Sky Sanctuary Zone) to eliminate Knuckles and recover the Master Emerald, but they are ultimately defeated by the guardian.

Sonic the Hedgehog Triple Trouble

Robotnik STT intro

Dr. Robotnik with a Chaos Emerald.

In the 1994 title Sonic the Hedgehog Triple Trouble, Dr. Robotnik had all of the Chaos Emeralds on his hands. However, a Badnik of his screws up and accidentally drops them, with the doctor managing to save one. Robotnik, knowing that Sonic and Tails were bound to come, tricks Knuckles the Echidna into believing that Sonic and Tails are out to steal the gems, thus creating a convenient distraction for them on their way to defeat the mad doc.

Robotnik, however, also has to contend with Fang the Sniper who is out to steal the emeralds for profit. Eventually, Knuckles is defeated by Sonic and Tails, ending up captured by Robotnik in an energy cage in the Atomic Destroyer. Robotnik then leaves Metal Sonic to deal with Sonic and Tails. When Metal is defeated, Robotnik himself faces the heroic duo, but is beaten once more, dropping the last Chaos Emerald and fleeing. After their final confrontation with the mad scientist, Sonic and Tails find Knuckles, proceeding to free him from his prison and befriending the echidna as well, sharing a handshake before escaping all three together.

Sonic 3D Blast

In Sonic 3D Blast, Dr. Robotnik learns of the Flickies, a bird species who are able to transport between dimensions, and thus wants to use their abilities to help him gain the Chaos Emeralds. Sonic, Tails, and Knuckles decide to visit their friends at Flicky Island; however, all they see is a bunch of Badnik robots.

Sonic vows to defeat Robotnik and save them, with Tails and Knuckles helping out along the way. Robotnik is eventually defeated once again, and peace is restored to Flicky Island.

Sonic the Fighters

Robotnik Fighters

Dr. Robotnik prepares to conquer the world from his Death Egg II.

In Sonic the Fighters, Dr. Robotnik rebuilds the Death Egg, and uses it to destroy the world. Tails, upon discovering this, builds a rocket powered by the mysterious eight Chaos Emeralds.

He holds a competition to see who gets the gems. Sonic, Tails, Amy, Knuckles, Fang, Bean the Dynamite, Espio the Chameleon, and Bark the Polar Bear all participate in the tournament, fighting one another to see who reaches Robotnik.

Eventually, the winner reaches the Death Egg II, and defeats Metal Sonic and Robotnik at the Death Egg, saving the world once more.

Knuckles' Chaotix

In Knuckles' Chaotix, a mysterious island is formed due to the power of the Master Emerald. Dr. Robotnik travels to the place so he could exploit the ancient power of the Dark Ring to conquer the world, assisted by his right-hand minion, Metal Sonic.

Knuckles arrives to investigate, and sees Espio being held prisoner. The echidna also frees Mighty the Armadillo, Vector the Crocodile, and Charmy Bee, and works together with them to stop Robotnik. They are joined by two defectors from Robotnik, Heavy the Robot and Bomb.

In the end, Knuckles and his crew manage to gather all of the six Chaos Rings (which held the Dark Ring's power) and defeated Robotnik again.

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 defeated, 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 also failed to defeat Sonic and was destroyed, and Robotnik's base was leveled.

SADX Super Sonic story intro

Eggman and Knuckles having been knocked unconscious by Chaos.

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 the Hedgehog Pocket Adventure

In Sonic the Hedgehog Pocket Adventure, Dr. Eggman returned to kidnapping Animals to use as Badnik power sources, which prompted Sonic to go after the doctor to stop him.

EggmanStealsEmerald

Eggman steals Knuckles' Chaos Emerald.

While pursued by Sonic, Eggman confronted the hedgehog many times. Each time though, Eggman was beaten and forced to flee. Eventually though, Eggman ambushed Sonic and Knuckles after Sonic defeated Knuckles in battle and took his Chaos Emerald. Stealing the Emerald, Eggman left his enemies to get buried in the collapsing cave they were in and fled to a secret base. When Sonic later caught up to him, Eggman used a trap door he had set up that dropped Sonic deeper into his base. However, Sonic soon caught up to Eggman, much to the scientist's surprise, who tried disposing of Sonic with a new weapon. When this failed, Eggman fled to the Last Utopia Zone where he used a mech powered by his Chaos Emerald to confront Sonic. However, Sonic quickly defeated the mech and took back the Emerald, forcing Eggman to flee into space. There, Eggman armed himself with his final mech when Super Sonic came after him. Upon his mech's defeat, Eggman's Egg Mobile was dealt a crippling blow by Sonic, leaving Eggman to plummet down to earth.

Sonic Shuffle

In Sonic Shuffle, Dr. Eggman learned about the power of the Precioustone and followed Sonic and his friends into Maginaryworld in hopes of stealing the powerful gem.[15] Although he would confront Sonic and his party on several occasions, his plan ultimately ended up being thwarted.

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.

Sonic Adeventure 2 Eggman Entrance

Dr. Eggman attacks the military base on Prison Island.

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 would 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, forcing Eggman to withdraw his ultimatum. In addition, because the Eclipse Cannon was not fully charged with all seven Chaos Emeralds, he also was unable to make due with his threat due to it requiring a recharge time of several hours, although after Rouge the Bat revealed a hint to where the final Chaos Emerald was located (specifically, a newspaper article revealing that Tails was awarded a Chaos Emerald for saving Station Square), he then had Rouge track down Tails, and after sighting his plane telling Shadow to pursue them. Although Shadow ultimately wasn't able to stop them, Eggman was undeterred, as he already had anticipated the possibility of their arrival and made arrangements for it.

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 then gave a status report to Rouge about how they've escaped, and also ended up giving her the password for the computer files and the Eclipse Cannon (which was MARIA, just like the password for Shadow's capsule). Eggman later returned to the ARK after detecting two Chaos Emerald signatures, deducing that Sonic must have a decoy as well as the real one, also ordering Shadow to stand down as he intended to deal with them personally. 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. He then presumably either ambushed Tails or hijacked his communication lines and told him to tell Sonic that Amy is being held hostage. 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. He later informed them about the Biolizard's survival and merging with the space colony after their initial plan of having the Master Emerald neutralize the Chaos Emeralds failed.

Sonic Advance series

Sonic Advance

Eggman Advance intro

Dr, Eggman holds the Chaos Emerald in his hands.

Dr. Eggman, still determined to create his Eggman Empire, proceeded to utilize Roboticization of the various animals, as well as hunt down the Chaos Emeralds. He ended up meeting resistance from Sonic, Tails, Knuckles, and Amy. He fought them several times with various mechs (and in one case, indirectly fought against them), until they eventually reached his headquarters, XX, located in space. He then utilized two of his old mechs against them as well as a new mech. However, he was defeated. He eventually confronted Super Sonic on the moon, but ended up defeated.

Sonic Advance 2

Not one to give up, Dr. Eggman proceeded to continue with his goals of creating the Eggman Empire. In addition, he also managed to abduct Tails as well as a youngster named Cream, and also manipulated Knuckles into fighting Sonic, even supplying him with the Egg Saucer. However, Sonic managed to rescue them (and in Knuckles' case, put some sense into him), and eventually confronted Eggman at Area XX, alongside copies of the various mechs he used before. Despite the destruction of Area XX, Dr. Eggman did not give up. He then proceeded to use a mech to abduct several Flickies as well as Cream's mom, Vanilla, right in front of them. However, Sonic managed to transform into Super Sonic and defeat Eggman, also rescuing Vanilla.

Sonic Advance 3

Eggman SA3 intro

Eggman activates Chaos Control.

Ultimately, Dr. Eggman managed to find the Chaos Emeralds and use them and Chaos Control to rip the earth apart, separating Sonic from his friends in the process. He also developed several doomsday devices, including G-merl, a robot modeled after the deceased Gizoid Emerl. Sonic eventually managed to beat Eggman, however, and to make matters worse for them, G-merl betrays Eggman and steals the Chaos Emeralds, forcing Eggman to team up with Super Sonic to stop G-merl. It is implied during the credit scene of the true ending that Dr. Eggman brought an unconscious Sonic back to safety.

Sonic Pinball Party

In Sonic Pinball Party, right after having his latest attempt to conquer the world foiled by Sonic, Eggman went back to his old tricks by kidnapping the Animals coming to Casinopolis and turning them into badniks. In the meantime, Eggman would organize the Egg Cup Tournament and brainwash Tails and Amy into serving him.

Eventually, Sonic took part in the Egg Cup Tournament in order to foil Eggman's scheme. Along the way, Sonic saved his brainwashed friends, who had joined the tournament to stop him. When Sonic won the tournament however, Eggman appeared and challenged Sonic to an additional match. At the end though, Eggman was defeated by Sonic, who liberated Eggman's prisoners.

Sonic Battle

SB EP Sonic Eggman and Emerl

Dr. Eggman ordering the Gizoid.

Having used research notes made by Gerald Robotnik, he managed to locate a doomsday weapon known as a Gizoid. However, he eventually discarded it when it seemed to be useless. He later discovered that the Gizoid can only be activated by Chaos Emeralds and tried to get it back. Eventually, he managed to make copies of the Gizoid, rechristened Emerl. He eventually unveils his Death Egg, and uses its cannon to destroy a star. However, he becomes horrified when he learned that Emerl, due to his learning abilities, not only managed to learn the Death Egg's cannon at sight, but also aim the weapon directly at the Earth. He later witnessed Sonic being forced to kill Emerl.

Sonic Heroes

Eggman heroes

Dr. Eggman in 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 three 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.

Sonic Jump series

Sonic Jump (2005)

In Sonic Jump, Dr. Eggman had invented the "Brainwash Beam", a device that would allow him to take control of the minds of others. Building it on a space station so it would able to affect the whole world, all Eggman needed was the energy of the seven Chaos Emeralds to power it. While tracking down the Emeralds however, Eggman went after Tails when the fox cub caught wind of his activities. Kidnapping Tails right before Sonic's eyes, Eggman got onboard a helicopter with Tails and traveled to his flying fortress where he imprisoned Tails. Sonic soon after came to Tails' rescue though. Making his escape, Eggman warned Sonic that he had obtained six of the Chaos Emeralds, and that there was only one left to find.

Eggman subsequently traveled to Angel Island to get the last Chaos Emerald from Knuckles. While demanding the Emerald from the echidna however, Eggman would snatch it when Knuckles got distracted by Sonic and Tails' arrival. Eggman then gloated about his plan to the heroes before making his escape to South America, where he had a space station with a rocket that could take him to his Brainwash Beam in space. Although Sonic and co. were hot on his tail, Eggman managed to leave in his rocket before they caught him. Unfortunately for Eggman, Sonic would follow him into space and destroy the space station hosting the Brainwash Beam, which also scattered the Chaos Emeralds across Earth. Despite this, Eggman managed to get a hold of one of the Emeralds and hide out in space. However, Sonic soon tracked Eggman down and claimed his Emerald after defeating Eggman in his latest mech. In the aftermath, Eggman disappeared, although not before swearing revenge.

Sonic Jump (2012)

In Sonic Jump (2012), Dr. Eggman went back to his old ways by personally kidnapping Animals with his Egg Mobile and taking them high into the sky. However, his operations were soon discovered by Sonic and co. As such, while traveling the Zones, Eggman would repeatedly get cornered by the heroes and be defeated by them. Each time however, Eggman managed to escape to the next Zone, although not before capturing more animals. Eventually though, after being defeated in Mechanical Zone, Eggman tried fleeing into space, only for his Egg Mobile to give out. Crash-landing on Earth, Eggman begrudgingly abandoned his wrecked Egg Mobile and his plans.

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 is going to steal the Chaos Emeralds 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.

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 the Babylon Rogues accepted Eggman's offer. 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 give him the treasure, which was a magic carpet. Eggman passes out, disappointed at the treasure's apparent lack of value. He can be unlocked as a playable racer by completing the Babylon storyline.

Sonic Riders: Zero Gravity

Eggman upuszcza Arki kosmosu

Sonic and Jet reclaim the Ark of the Cosmos stolen by Eggman.

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. At 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, Dr. Eggman held another World Grand Prix and would award the winner with large amounts of cash and treasure. Besides Team Heroes and Babylon Rogues, Team Dark and Team Rose also participated in the event. In an attempt to disguise himself, he is dressed like a king and calls himself "King Doc of Toreggmania").

After what seemed to be the race finals of the World Grand Prix, Eggman announced there would be more final races for the contenders to participate and has constructed the "Ultimate Gear-jockey" (E-10000B) to participate. After the race, he decides to drop the disguise, and reveals that his robot has been copying everyone's racing data to make himself the fastest Extreme Gear racer. But the data turns out be useless as it was revealed that Metal Sonic has stolen the data for himself and gave Eggman false data, much to to the doctor's anger. After witnessing Sonic racing against Metal Sonic, Eggman berated at Metal Sonic for ruining the World Grand Prix and proceeded to leave, and it was revealed that Eggman did not actually have any prizes to award anyone with.

Sonic the Hedgehog (2006)

Eggman 06 Final

Dr. Eggman as he appeared in 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.

Eggman informing Shadow that if he wants more information about the Solaris Project, Shadow should bring Mephiles to him.

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 in this story, as his actions, as suspected by Silver, would have ultimately unleashed Iblis, thus plunging the world and its future into an apocalyptic state. Ironically, both times he appeared had him abducting Elise and escaping before Silver would have ended up killing Sonic, thus ensuring that Iblis did not end up released via Elise shedding tears.

Eggman witnessing Solaris's battle along with Sonic's friends.

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.

In this game, it seems that Sonic and Eggman, despite being bitter enemies, share a mutual respect for each other as when Eggman presumably perishes in the crash and explosion of his Egg Carrier with Elise, Sonic travels back in time to not only save Elise before the crash, but allow Eggman a chance to escape his doomed vessel as well when he battles Sonic in the Egg Wyvern. When Sonic is presumed dead by everyone after being impaled by Mephiles, even Eggman shows some remorse and grief over his arch-enemy's death and hence why he lends his support to locate the Chaos Emeralds to revive him.

Sonic Rivals series

Sonic Rivals

Doctor Eggman appeared in Sonic Rivals released for the PSP, where he actually played a heroic role in contrast to his evil deeds in almost every other occasion. Throughout the game, it was revealed that Eggman Nega (as Dr. Eggman's descendant) masqueraded as the doctor himself and captured the real Doctor Eggman in a card with Nega's special camera. With the aid of Shadow and a new hedgehog character, Silver, the doctor was rescued and helped 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 made Shadow and Metal Sonic team up for his attendances. In the game, Eggman seemed 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 show the page to Eggman, demanding an explanation. Eggman, shocked about them having found the page, fails to explain and runs off.

Sonic Unleashed

Eggmanunleashed

Dr. Eggman at the head of his cosmic fleet.

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 the Hedgehog 4

Episode I

In Sonic the Hedgehog 4: Episode I, which takes place shortly after the events of Sonic the Hedgehog 3 Knuckles, Eggman was left angry, humiliated, and vengeful at his defeat at the hands of Sonic, for not only destroying the Death Egg, but thwarting his plains with the Master Emerald. And due to this, Eggman laid low for a while, before Sonic parts with Tails and Knuckles to take a much-deserved break from his adventures. Determined to get his revenge on Sonic, Eggman redesigned selected inventions to be trickier than ever for Sonic to handle. Sonic was left oblivious to Eggman's presence until he ran into some familiar Badniks. After realizing that Eggman has returned, Eggman eventually confronts Sonic at Splash Hill Zone, but is defeated by Sonic. The two battled each other through various Zones, until Eggman eventually retreaded to his E.G.G. Station Zone. Not content with this, Sonic jumped onto a rising rocket and pursued the doctor. Onboard the E.G.G. Station, Eggman attacked Sonic with all of the past battle machines constructed by him, until they confronted each other when Eggman used an improved model of the Death Egg Robot. Despite the the mech's improvements, and Dr. Eggman's best efforts, Sonic ultimately defeated him, and escaped the base as it began exploding.

Episode II

Dr. Eggman resurrecting Metal Sonic. 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 so they can 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 Colors

Avcc

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 turns out to be 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 turned over a new leaf, but the act doesn't fool Sonic one bit. He sends out lots of robots to destroy Sonic, but these 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 the cannon. Eggman challenges 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 backfires.

After the credits, Eggman had survived the black hole and is seen helplessly stranded in space with Orbot and Cubot. Cubot celebrated getting his voice back and kept on talking, despite Eggman wishing for a moment of silence.

Sonic Generations

Eggmen

Modern and Classic Dr. Eggman in Sonic Generations.

In a surprise twist, Dr. Eggman of the present, named Modern Eggman, and his past self from another dimension, named 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 rescued Classic Eggman 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 fails to 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 both Modern Sonic and Classic 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 Eggmen 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 (although Classic Eggman is seen clutching his forehead and shaking his head as Modern Eggman says this).

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. During that time, he also proceeded to hone their abilities and provided them with the most powerful mechs he could create, and presumably also attempted to buy their loyalty by preparing them a giant sandwich.

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.

Eggman beginning to notice that something wrong has happened to his mustache.

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-nemesis. 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. However, Eggman had actually 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 mustache: the duo mention this by mistake and soon flee from a very angry Eggman.

Sonic Runners series

Sonic Runners

Sonic Runners Dr Eggman

Dr. Eggman in Sonic Runners.

In Sonic Runners, Dr. Eggman returned once more to conquer the world. To this end, he spent the next period attempting several malicious plots to his benefit with the aid of his lackeys, such as kidnaping Animals to use as power sources, hunting Wisps on Earth to harness their Hyper-go-on, harassing Chao with his construction efforts, building new and improved Badnik armies, and attempting to procure the Master Emerald. Every step of the way however, his plans got foiled by Team Sonic.

For his final scheme, Eggman revised one of his old plans by building another Brainwashing Laser to control the world with, except this time it would be powered by the Chaos Emeralds. Although Team Sonic kept interfering with his operations, Eggman was succesful in extracting all the chaos energy from the Emeralds for his laser. When it came to the final showdown with Team Sonic, Eggman tried using his Brainwashing Laser on Sonic after the doctor was defeated by him. However, the Chaos Emeralds that Sonic held absorbed the energy from the laser and transformed Sonic into Super Sonic. As Super Sonic destroyed his laser, Eggman snuck away to plot his next scheme.

Sonic Runners Adventure

In Sonic Runners Adventure, Dr. Eggman began another attempt to brainwash the world into serving him. For this scheme, Eggman build another mind control cannon, one powered by the latent energies in Sky Sanctuary and a new Extractor.

Arriving on South Island, Eggman captured Tails using his mind control ray and forced hin to build him a robot teleporter. While Eggman built up his Badnik army however, Sonic would arrive and free Tails before confronting Eggman. Forced to retreat by the blue hedgehog, Eggman fled to Desert Ruins through Tails' teleporter. After Tails then made a mess of Eggman forces and defeated him in battle, Eggman fled to Lava Mountain. There, Knuckles shut down Eggman's Extractor despite Eggman's attempts to stop him. Fleeting to Sky Sanctuary after that to salvage what remained of his plans, Eggman managed to escape Sonic by using his mind control ray on him. However, Team Sonic destroyed Eggman's mind control cannon not long after. Eggman was then dealt another defeat by Sonic. Making another escape, Eggman promised the heroes revenge.

Sonic Forces

SFRoI P2

Eggman discovers the power of the Phantom Ruby.

In Sonic Forces, months before making any moves, Dr. Eggman found the Phantom Ruby outside his lair while having a mental block. Upon picking it up, the Ruby gave him a vision of Eggmanland, only for the vision to evaporate when he dropped the Ruby. Realizing that the visions could be useful, Eggman proceeded to research the Ruby. Shortly after formally giving the Ruby its name, however, he had to deal with the Jackal Squad invading his turf. Since Eggman had spent his time researching the Ruby rather than maintaining his defensive measures, his outrage caused the Phantom Ruby to create several Egg Pawn replicas that held off the Jackal Squad. However, he was almost killed by their leader. The leader's sword, however, hit the Ruby and caused a vision of a desolate wasteland to appear, stunning the leader long enough for Eggman to knock him away. Impressed by the leader's abilities and his vision, Eggman offered to make him the leader of his army, which the captain accepted.[16] Eggman later tested out the Phantom Ruby's powers on Angel Island, leaving Knuckles and Silver to the Ruby's illusions. After Knuckles and Silver reverted the Phantom Ruby's effects, Eggman watched them take off and was delighted that the test was a success.[17]

Because of how important the Phantom Ruby was to his plans, Eggman had the lab researching it at Mystic Jungle guarded by the Jackal Squad. There, Eggman produced artificial duplicates of the Phantom Ruby called "Phantom Ruby prototypes". However, most of them had a defect that left them unusable to anyone else except one with the fortitude to trigger them.

Eventually, Shadow the Hedgehog attacked Eggman's lab in Mystic Jungle. With the Jackal Squad wiped out by Shadow, Eggman dispatched their captain. The captain was no match for Shadow, which, thanks to Shadow's blunt criticism, prompted him to be fused with Eggman's finalized Phantom Ruby prototype. Eggman had his own personal motives for approving of the leader, rechristened Infinite, undergoing the procedure: In particular, he wanted to create an "invincible weapon of destruction" to use on Sonic when the time came and let him expand the Eggman Empire across the globe. The fusion gave Infinite the Phantom Ruby's powers, including its ability to create replicas, which Eggman had Infinite use to supply him with replica soldiers for his army.

Shortly after completing his experiments on Infinite, Eggman's base in Green Hill was infiltrated by E-123 Omega. To deal with the traitorous robot, Eggman dispatched Infinite, who easily handled Omega, as a test of his new abilities.[18]

Eventually, Dr. Eggman invaded the City with his army, only for Sonic to arrive, just as he intended. Having anticipated Sonic coming to the rescue, Eggman unveiled Infinite and the replicas of Zavok, Shadow, Chaos, and Metal Sonic accompanying him. Together, these foes defeated Sonic, whom Eggman imprisoned on his newly rebuilt Death Egg. There, Eggman kept Sonic locked up so he could have him see his empire upon its completion, before banishing him into space. Without Sonic opposing him, Eggman conquered over 99% of the world over the next six months with the aid of Infinite and his replicas. It was during this war that the Resistance was formed to fight back against Eggman.

At some point during his conquest, Eggman invaded the City with robots deployed from his battleship. However, the battleship's launch bay got hit with a missile, preventing any more robots from functioning. Due to this, Eggman retreated, but swore revenge.[19]

Eventually, Eggman sought to dispose of his remaining Phantom Ruby prototypes so they could not be used against him. Eggman later appeared in Green Hill to talk with Infinite while the latter destroyed his prototypes. He then grew angry at Infinite for not killing Sonic, who had broken out of the Death Egg, at Mystic Jungle, but nonetheless reviewed with him the final stages of his plan to wipe out the Resistance and perfect the Eggman Empire upon the ashes of the old world. Shortly after Infinite took his leave, however, Eggman was attacked by Classic Sonic, who had arrived in Eggman's dimension due to the Phantom Ruby. Eggman initially attempted to disengage from fighting Classic Sonic due to viewing him as not worth his time, but ultimately fought him with his various mechs, before being beaten. Already confident in his victory against the Resistance, he took the loss in stride, and even proceeded to gloat to Tails (who was accompanying Classic Sonic) and Classic Sonic that his plan to wipe them out would be accomplished in three days' time before taking his leave.

While his army fought the Resistance for him, Eggman began shifting his forces to the Eggman Empire Fortress in preparation for his plan to wipe out the Resistance. This left his HQ in Metropolis undermanned, prompting the Resistance to launch a full, frontal assault on the city. Eggman, while surprised by the resistance's boldness, took care of them by sending Infinite, who forced the Resistance to retreat. Despite their losses, the Resistance managed to uncover the Phantom Rubies' weakness, reclaim portions of the world, and blow up the Death Egg, which also served as a energy source for the Phantom Rubies.

Setback

Eggman observing his setbacks.

Infuriated by the Resistance, Eggman and Infinite retreated to Metropolis until their final plan could be executed. There, Eggman was found by Sonic and Tails, who sought to capture him. However, the villain revealed one of his trump cards by instructing Infinite to form a portal into Null Space, which sucked in both Sonic and the Avatar after the former attempted to save Sonic. Tails voiced his shock at the Phantom Ruby's continued power despite the Death Egg's destruction. In response, Eggman revealed that he had a backup power-source hidden beneath the Eggman Empire Fortress. While losing his city to the Resistance however, Eggman saw, much to his shock, that Sonic and the Avatar had escaped from Null Space. Infuriated, he retreated to his fortress to enact his final plan.

When the Resistance came to the fortress to end the war, the organization fought the hundreds of replicas of Chaos, Shadow, Metal Sonic, and Zavok that were under Infinite's control. Despite Omega showing up aid to the Resistance, Infinite enacted Eggman's endgame: using his Phantom Ruby prototype, Infinite created a second sun, which began a collision course with the planet. Eggman then revealed his intentions to use this sun to completely destroy the Resistance. However, Eggman's doomsday plan was foiled when the Avatar used a Phantom Ruby prototype Infinite had missed to neutralize the second sun. Expressing disbelief that his plans were once again ruined, Eggman had his fleet, army, and Infinite launch a defensive attack. Meanwhile, Sonic and the Avatar soundly defeated Infinite. Eggman then arrived and expressed his admiration for Sonic's ability to always impress him. Revealing that he had one final play in hand however, Eggman retreated while the Resistance destroyed his backup reactor for his Phantom Rubies.

SF LAUNCH8

Eggman in the cockpit of his Death Egg Robot.

While Sonic believed that they had won, Eggman reappeared in a Death Egg Robot with the original Phantom Ruby incorporated into it. Proclaiming himself as Infinite's successor, Eggman used the Ruby to conjure up thousands of replicas to fight the resistance. When Classic Sonic and the Avatar managed to destroy the outer shell of the robot, Eggman ejected the core and created a dimension to have his final battle with them and Sonic. In the end, Eggman was defeated when the trio dealt his mech a final blow that destroyed the Phantom Ruby. As the Death Egg Robot exploded, the dimension collapsed and all the replicas disappeared, allowing the Resistance to claim victory.

Team Sonic Racing

In Team Sonic Racing, Dr. Eggman observed the Grand Prix organized by Dodon Pa, who had convinced Team Sonic, Team Rose and Team Vector to participate in it. Eventually though, Eggman decided to step in and a throw a wrench into the heroes' plans. Having invented the Egg Booster for himself and appointed several Eggpawns as his teammates for Team Eggman, Eggman was ready to enter the Grand Prix himself. In the meantime, he had Orbot and Cubot remain on standby onboard his Final Fortress where they maintained his airship and vegetable garden.

EggmanTeamSonicRacing

Dr. Eggman making his entrance at the Grand Prix.

Arriving at the Grand Prix alongside Team Dark, Team Eggman was introduced to the other racers by Dodon Pa. Tails immediately accused Eggman of being behind the Grand Prix, but Eggman insisted that he was only here to race. As Eggman bragged that his team was unstoppable, Sonic countered with a taunt.

During a race between Team Sonic and Team Dark, Dr. Eggman intruded on the two teams' race to compete alone under the pretense that he was there to race as a special guest. Although Dodon Pa knew it was a lie, he nonetheless allowed Eggman to compete, much to Eggman's surprise. As Sonic and Shadow began to gang up on him, Eggman asked Dodon Pa for help, who advised him to make use of the Wisp power-ups on the race tracks. Taking Dodon Pa's advice, Eggman used the Wisps to take the lead. However, Sonic and Shadow soon after took the lead again. Although Eggman saw this as little more than a temporary setback, he soon found himself surrounded by the other racers in the Grand Prix, who took him out with a combined Wisp assault. Although Eggman lost, his performance had taken up so much of Dodon Pa's attention that the Tanuki did not see whether Sonic or Shadow won the race, much to Eggman's joy. Still, Eggman moped that would have won if he had a team, to which Dondo Pa replied that he looked forward to his continued participation with a team since Eggman's passion against overwhelming odds was inspiring.[20]

Soon after, Eggman met up with Dodon Pa to discuss science with him. During their conversation, the Ultimate Energy Engine was brought up. This engine, which Donpa Motors was currently developing, was going to be the fastest and most powerful engine in the universe. After hearing about it, Eggman plotted to steal the Ultimate Energy Engine. Some time after, Eggman lost a race to Sonic, who asked him how many times he had been defeated by now. While Eggman replied that he did not keep scores, Orbot tried to provide the exact number. However, Eggman had Orbot zip it, and decided to up his game. Soon after, Eggman sent hundreds of Eggpawns after the racers on the race tracks. While the heroes managed to clear out the Eggpanws, Eggman promised that this was not the end, as he could built Eggpawns faster than they could destroy them. As the Grand Prix progressed though, Eggman and his team were not doing too well. Frustrated at his constant loses, Eggman concluded that something was wrong with his car, prompting Orbot to throw a sarcastic remark at him. After getting Orbot to shut up, Eggman decided to introduce an even better car: the Formula M. In addition, Eggman had Metal Sonic join his team so he could drive the Formula M.

Seeking to have someone steal the Ultimate Energy Engine, Eggman hired Zavok for the task. Before one of the races, Eggman secretly contacted Zavok, and gave him instructions to follow. Afterward, Eggman decided to have his team keep racing for now. Later, Eggman was getting more and more excited about the obtaining the Ultimate Energy Engine. While Eggman thought his plan infallible however, Orbot had listed several ways for it to fail, prompting Eggman to chide Orbot. Soon after though, Zavok was discovered by Sonic and the other racers. When Sonic asked Eggman if he was with him, Eggman faked ignorance. Regardless, he still had Zavok join his racing team, and provided him with the Road Dragoon. After the race, Eggman chided Zavok for letting himself be discovered. To make matters worse, Zavok had failed to located the Ultimate Energy Engine, making Eggman even more angry. Regardless, Eggman hoped that Zavok could prove himself on the race track. Not long after, Eggman heard Dodon Pa talk publicly about how he was developing the Ultimate Energy Engine. Later, before another race, Eggman was approached by Silver, who began interrogating him about what he and Dodon Pa talked about earlier. Seeing through Eggman, Silver correctly deduced Eggman's mission, his plan with Zavok, and his intention to use the engine for his own gain. Meanwhile, Eggman thought about using the engine to destroy Sonic. Having failed to cover up his intentions, Eggman instructed Metal Sonic and Zavok to win the next race at all costs. However, after a series of more defeats, Eggman would insulting Zavok and criticize his skills. Eventually though, Eggman offered Zavok a task he was more suited for: kidnapping Dodon Pa.

After Dodon Pa was kidnapped and brought onboard the Final Fortress, Eggman demanded to Dodon Pa that he handed the Ultimate Energy Engine over to him. However, Dodon Pa revealed that it was unfinished, making it useless. Furthermore, the racers had stopped racing, and without them producing Ultimate Team Energy, the engine could never be finished. Zavok then pointed out to Eggman that this was Eggman's own fault: by kidnapping Dodon Pa, he had brought the Grand Prix to a halt and stopped the racers from producing the necessary energy. Rather than taking responsibility for his actions though, Eggman tried to figure out a way to fix this mess. As Sonic and the other racers arrived to save Dodon Pa however, Eggman decided to trick the heroes into racing his henchmen and produce the rnergy they needed to finish the engine. By lying that he would set Dodon Pa free if they beat him in a series of races, he got Sonic and co. to race his Eggpanws, then Zavok, and then Metal Sonic. In the final face, Eggman had the heroes race him as well (although he felt he made a fool out of himself on the track). In the end though, Dodon Pa finished the Ultimate Energy Engine, which Eggman promptly stole and incorporated into his monster machine, which Eggman planned to crush Sonic with. Eggman subsequently pitted his monster machine against all the racers, but Sonic still beat it. Eggman then planned to use the monster machine to crush Sonic and his car. Unfortunately, the monster machine went crazy and drove into the Final Fortress's energy core, causing the airship to start crashing. This prompted Eggman to escape the Final Fortress with his lackeys.

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 SegaSonic Cosmo Fighter etc., or appearing as a cameo such as in Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS..

Sonic the Hedgehog Spinball

Veg-O-Fortress

Sonic and Tails attacking the Veg-O-Fortress.

In both versions of Sonic the Hedgehog Spinball, in an attempt to turn the Animals of Planet Mobius into robots, Dr. Robotnik took control of Mount Mobius. On this mountain, the doctor created the Veg-O-Fortress, a fiendish contraption powered by the mountain's volcano, which was robotizing Animals at an incredibly fast rate. To protect his fortress, Robotnik constructed a lethal defense system powered by the volcano, called the Pinball Defense System. Sonic and Tails soon mounted an air assault on the fortress, only to get blasted by Robotnik's cannons. Unfortunately for Robotnik, Sonic surived the attack and began making his way up through the Veg-O-Fortress's defense system, seizing the Chaos Emeralds that kept the fortress stable and freeing the Animals of Mobius along the way.[21] When the Veg-O-Fortress began to crumble, Robotnik tried to escape in a spaceship, but got intercepted and defeated by Sonic. Falling from space upon his defeat, Robotnik landed in the sea around his Veg-O-Fortress, just as it sank into the sea.

In the game, Robotnik serves as the final boss. On the Sega Mega Drive version of the game, he is fought in Robotnik's Ship, and on the Sega Game Gear/Sega Master System version of the game, he is fought in Final Showdown.

Wii U Trophy
Name Picture Description
Dr. Eggman DrEggmanTrophyWiiU NA: Dr. Eggman knows a great deal about robots, which is neat. He also knows how to turn animals INTO robots, which isn't so neat. You'd think a man with an IQ of 300 would stop going up against Sonic, but he keeps on trying, all to build a world around his Eggman Empire.

PAL: Here is a man who immortalises animals in mechanical form because he just loves them so much! Wait. That's not quite right... Instead of using his talents for peaceful ventures, Dr. Eggman, a scientist with an IQ of 300, nurtures plans for Eggmanland to reach all four corners of the world. First poaching animals, now this? Terrible.

In Sonic Dash, as of update 1.10, Dr. Eggman appears as a boss in the game. During the fight, Eggman will be piloting the Egg Mobile, which has been equipped with extra rockets/missile launchers.

During the first phase of the fight, Eggman will fire missiles from the rear which the player has to avoid. For the next phase of the fight, Eggman will fly ahead of the player, from where he will drop Bombs on the road in different formations. The player's only option at this point is to dodge the bombs. The next phase focuses on attacking Eggman. During this phase, Eggman will try to fly away, only for the playable characters to reach him using a Spring. The player then has to tap the green target reticles that appears, which will make the playable characters attack Eggman. After landing three hits, Eggman will be defeated and the player will receive points. If the player misses a hit though, the doctor will escape without the player receiving points.

Archived from the original on June 5, 1997. "Yuji Naka: Robotnik was created to be the opposite of Sonic, and to be the bad guy. At that time, there was opposition between "developers" and "environmentalists", and Robotnik was created to represent machinery and development. As far as design, Mr. Oshima (the team member in charge of character designs) was trying to create something easy enough so that kids would be able to draw the characters. That's why the rotund character was created."
