I'm going to enslave humanity and force them to service my machines. First, Green Hills. Then the universe. Then the multiverse. Then who knows? Maybe that'll be enough. Full disclosure? You won't be there.

— Dr. Robotnik, Sonic the Hedgehog 2 (film)

Doctor Robotnik[1] is the main antagonist of the Sonic the Hedgehog film series produced by Paramount Pictures and its spin-offs. He is an evil and misanthropic human scientist who plots to conquer the multiverse and enslave humanity to force them to service his machines. He is also the arch-enemy of Sonic the Hedgehog.

Originally an United States operative with a revolutionary robot army at his disposal, Robotnik and his assistant Agent Stone were sent to investigate a blackout originating from Green Hills, Montana. What he found, however, was an extraterrestrial alien named Sonic with incredible powers. After Sonic escaped from him with the aid of Tom Wachowski, Robotnik began hunting Sonic in order to dissect him and undercover the secrets of his power. Upon learning the magnitude of Sonic's power however, Robotnik set his sights on using Sonic's power to conquer the world. During his final attempt to capture Sonic however, he was defeated by the alien and banished to the Mushroom Planet, where he would plot his return.

Several months later, Robotnik allied himself with Knuckles the Echidna to take revenge on Sonic, although his plans changed when he discovered the existence of the Master Emerald and sought to obtain its power by manipulating Knuckles. After obtaining the Master Emerald, the doctor used his newfound power to start his plans of conquest and have his genius recognized across reality until Sonic defeated him, leaving his current whereabouts unknown.


Dr. Robotnik is an average-sized human. He originally possessed dark brown (almost black) hair, light peach skin, brown eyes, a short mustache and ample stubble across his jawline. His hair was usually combed back, and his mustache was usually thin and dark brown (almost black) with handlebar curls at the ends. For attire, he usually wore a black trench coat with customized tails and red piping, a dark grey tunic, black trousers, black shoes, black gloves, black sunglasses and a pair of Robotnik Control Gloves. When later piloting his Eggpod, he donned a red flight suit with black and brown accents and black goggles with red lenses.

After spending nearly three months alone on the Mushroom Planet, Dr. Robotnik adopted a significantly different appearance: he shaved his head completely bald, he let his mustache become overgrown, unkempt, and more mahogany in color, his nose gained a notable pinkish-red sunburn, and the sleeves of his flight suit had been torn off.

After Knuckles helped Robotnik escaped the Mushroom Planet, Robotnik changed into a red and black overcoat, black pants, black boots and new Robotnik Control Gloves.


Film series


Growing up an orphan, Robotnik came to resent family and the human society. While attending school, Robotnik was harassed by a school bully, who punched him in the face in the cafeteria, giving him a black eye and humiliated him in front of the whole school. However, instead of reporting him to the principal, Robotnik achieved revenge on his bully through technological means, leaving the bully to spend the next year eating through a straw.

Over time, Dr. Robotnik managed to get five PhDs. He was also trained in tracking by the Native American Shadow Wolves. He was employed by the United States government at one point as well and became known for his revolutionary drone technology. Over the course of his career, he gained a perfect operations record and allegedly helped with several incidents, including a coup in Pakistan and an uprising in Azerbaijanistan, while simultaneously developing a notorious reputation that left his superiors unwilling to involve him in most affairs.

Sonic the Hedgehog

When an electromagnetic pulse of unknown origin caused a blackout all over the Pacific Northwest. Robotnik was assigned by the Pentagon to quickly and quietly determine and resolve the cause of the phenomenon, if proven hostile to the United States. Upon his arrival near Green Hills, Montana with his assistant Agent Stone, Robotnik immediately made himself the chief of the local operations conducted by the United States Army, humiliating Major Bennington in the process. Afterward, he proceeded to have his aerial Badniks do a sweep of the area within a ten-mile radius. When one of them found a strange footprint, Robotnik scanned and studied it. Discovering that the footprint did not belong to any known being in the Earth's animal kingdom, Robotnik deduced that he was dealing with "something else entirely" related to the blackout.

Tracing the footprints to the residence of Tom Wachowski. Robotnik introduced himself as a representative from the power company investigating the blackout. However, Robotnik had his lie revealed when Tom outwitted him. As such, Robotnik secretly sent aerial spy Badniks to do a reconnaissance of Tom's house. As Robotnik revealed his intentions and threatened Tom when he denied him permission to check his home however, he forced himself inside his house when he heard a noise. At first, he was led to believe that the noise was made by raccoons, but then he found a strange blue quill. Knowing now that Tom was hiding something, Robotnik threatened Tom by ordering one of his aerial Badniks to kill him if he did not tell him where the creature he was hunting was. Suddenly however, an anthropomorphic blue hedgehog named Sonic revealed himself, pleading Robotnik not to harm Tom. The sight of Sonic shocked Robotnik so much that Tom managed to stun him with a punch to the face. As Tom then made his escape with Sonic, Stone came to Robotnik's aid. However, Robotnik reprimanded Stone for prioritizing his well-being over the capture of Sonic and Tom. Resolving to capture Sonic and see what made him tick by dissecting him, Robotnik returned to his truck-based center of operation outside Tom's house and had Stone bring Sonic's quill along.

Occupying the Green Hills Sheriff's Department, Robotnik and his agents personally overheard a conversation between Tom and Wade when the former called him. Growing impatient, Robotnik snatched the phone from Wade and told Tom of how he had gotten on his bad side. As Robotnik threatened Tom however, Tom hung up. Leaving Wade behind, Robotnik traced Tom's last known location to the Piston Pit, where he and Stone managed to successfully interrogate a Roadhouse Thug who had met Sonic and Tom earlier.

Having deduced that the pair were heading for San Francisco, Robotnik calculated their approximate location and sent an armored tank-like Badnik after them. When Sonic destroyed this Badnik however, Robotnik deployed a smaller one from the wreckage to continue the chase. Though Sonic managed to destroy this Badnik as well, Robotnik released a one-wheeled Badnik from its wreckage. However, it was destroyed by Tom, infuriating Robotnik. Using his last resort, Robotnik launched a miniature Badnik from the wreckage that crippled Tom's truck and got a bomb stuck on Sonic. Unfortunately for Robotnik, Sonic and Tom managed to remove the bomb before its exploded. Frustrated by his failure, Robotnik was about to take it out on Stone, but then noticed Sonic's quill was pulsating with energy. Deciding to analyze the quill, Robotnik ran a number of analyses while putting on his own little performance for his own amusement until Stone interrupted him with a latte. It was then that Robotnik discovered that Sonic's quill held unlimited energy. Realizing his machines could reach their full potential with this power, he ordered Stone to ready the Eggpod.

Robotnik attacking Sonic on the Transamerica Pyramid, from Sonic the Hedgehog (film).

Taking the Eggpod and his Badniks to San Francisco, Robotnik cornered Sonic, Tom and Maddie on top of the Transamerica Pyramid. After bantering with the trio, Robotnik saw, to his slight surprise, Sonic push Tom and Maddie off the Transamerica Pyramid. As his Badniks fired upon Sonic however, the hedgehog used his super speed to dodge Robotnik's assault and go after Tom and Maddie. However, by harnessing the power of Sonic's quill, which had been hooked up to the Eggpod, Robotnik gave his vehicle the power to keep up with Sonic. Robotnik proceeded to fire upon Sonic, nearly foiling Sonic's plan to send Tom and Maddie to Green Hills with a Ring. With Sonic refusing to surrender himself to him, Robotnik began chasing Sonic in his Eggpod, following him through the Ring portals he made. After their chase having led them through Paris, along the Great Wall of China, and into Egypt, Robotnik managed to get a shot in on Sonic, sending him flying through a Ring portal to Green Hills. Arriving in Green Hills' main street himself, Robotnik loomed over the injured Sonic before the latter passed out. However, Robotnik was interrupted when Tom got behind him using a Ring and surprised him with a sneak attack.

While Robotnik managed to knock Tom off his Eggpod, his attempt to kill him was interrupted when the people of Green Hills stood in his way. Regardless, Robotnik rebuked the people for standing up to a foreigner like Sonic. As Tom declared Sonic his friend however, Sonic came to his senses and unleashed his full power. Sonic then began draining the Eggpod of his power while announcing his resolve to protect his friends. Robotnik proceeded to fire several missiles at Sonic, only for Sonic to dodge them all and cripple the Eggpod with numerous high-speed strikes. Making a final attempt, Robotnik charged at Sonic, only for Sonic to overpower his Eggpod's charge and knock both it and Robotnik into a Ring portal that Tom had opened to the Mushroom Planet.

Robotnik begins his path to revenge, from Sonic the Hedgehog (film).

Having survived his defeat and banishment to the Mushroom Planet, Robotnik spent the next three months on the alien planet, eventually losing his grip on sanity (despite his conviction to the contrary). He also let his mustache grow thick and unkempt and began keeping a stone with a human face on it that he named after Agent Stone. One day, after shaving his head completely bald, Robotnik logged into his glove computer that despite being trapped on an uninhabited planet with no resources except for his Eggpod parts and Sonic's re-energized quill, no supplies, and no apparent way home, he declared he would "I'll be home by Christmas" and sat out on a journey across the Mushroom Planet with his stone companion.

Sonic the Hedgehog 2

After being stuck on the Mushroom Planet for 243 days, Robotnik would begin the daily routines he had established for himself, musing about getting revenge on Sonic, before turning his attention to his masterpiece. Having constructed an energy beacon from the parts of his Eggpod in hopes of producing an energy signal that would attract the attention of those off-world, Robotnik would hook Sonic's chaos energy-infused quill up to his device in order to power it. Upon doing so however, Robotnik unleashed an energy pulse that knocked him unconscious. Hours later, some alien scavengers appeared from a Ring on the Mushroom Planet and found the unconscious body of Robotnik. When they reached for Sonic's quill however, Robotnik woke up and took the scavengers out with traps that he had set up before-handed. However, when he headed for the Ring portal in an attempt to escape the Mushroom Planet, he found his way barged by Knuckles the Echidna. When Knuckles asked where he had found Sonic's quill, Robotnik told that he got it from Earth and that he would happily show him the way. The two of them would then make a deal: Knuckles would get him off the Mushroom Planet, and Robotnik would show him where Sonic was.

Robotnik introduces Knuckles to Sonic, from Sonic the Hedgehog 2 (film).

Arriving in Green Hills during the night, Robotnik would cut off the power to Sonic's place of residence. He proceeded to cut the front door open with his control glove, revealing himself to Sonic. While Sonic insisted that Robotnik made a mistake by coming back, Robotnik told him otherwise as he promised revenge against him and the Wachowskis. As Sonic then charged at him, Robotnik stepped aside for Knuckles to take on Sonic. From there, Robotnik stood on the sidelines, watching with content as Sonic got pummeled by Knuckles as their fight ensued. During this however, Robotnik heard Knuckles mention the "ultimate power", which caught Robotnik's interest. Soon after though, Tails arrived in a police and saved Sonic from Knuckles by ramming the echidna with said car. As Sonic and Tails prepared to drive away however, Robotnik jumped onto the car's hood and acted rabid until he got thrown off of it.

After Sonic and Tails escaped, Robotnik would pursue both them and Knuckles on a riding mower, only to catch up to them in time to see Tails fly Sonic away. In order to proceed with his plans, Robotnik used his control glove to call Agent Stone, who sent him an orbital space pod with new clothes and Badniks. Getting refitted with new clothes, equipment and a refresher, Robotnik proclaimed that he had been "re-hatched." Finding Knuckles on the cliffside below him, Robotnik inquired Knuckles about the "ultimate power" he spoke of. Knuckles, however, told him that this power, the Master Emerald, did not concern him now that their deal was over. Insisting otherwise, Robotnik used his Badniks to help Knuckles up from the cliff and explained to him that he needed his expertise on Earth. Furthermore, he convinced Knuckles that he would help him find the Master Emerald so that he could use it to destroy Sonic. With Knuckles seeing that he was suggesting an alliance, Robotnik had them seal their deal with a handshake (which crushed his hand). Afterward, Robotnik pulled out his Egg Mobile for him and Knuckles to travel in.

Traveling to the Mean Bean Coffee Café in Green Hills, Robotnik found Stone, the owner of the café. There, Robotnik received his favorite latte from his faithful assistant, which he noted could use some mushroom. When Knuckles then came in and got acquainted with Stone. Robotnik ordered for the café to be renovated. In response, Stone activated the command center that he had secretly installed into the establishment. While there, Robotnik and Stone intercepted a test message between Sonic and Tom Wachowski. As Stone took notice of Knuckles' lack of understanding of technology and asked him why they were working with an "imbecile", Robotnik told him of his plan to steal the Master Emerald, which would not only let him get revenge on Sonic, but also let him power his wildest designs, get his genius recognized across the galaxy and let him harness unimaginable forces. When Knuckles deduced from the message that Sonic was back home, Robotnik proved him wrong by tracing his call to eastern Siberia. After they then had fiddled with a hologram of Sonic, Robotnik and Knuckles headed for Siberia. As they left though, Robotnik chose to ditch Stone for now, which Knuckles called him out for being dishonorable. Robotnik, however, did not care.

Using the Egg Mobile, Robotnik and Knuckles found Sonic and Tails inside an ancient owl temple in the mountains, arriving there with an army of Badniks, just as Sonic and Tails had acquired a compass that could lead them to the Master Emerald. Following some banter with Sonic, Robotnik fired a missile at Sonic with his Egg Mobile, only for Sonic to redirect it into a statue, causing the entire temple to start caving in. Sonic and Tails, however, managed to escape through an opening. As the duo then split up, Robotnik went after Tails. During the ensuing pursuit, Robotnik managed to snatch the compass when Sonic tried passing it onto Tails, before firing a pair of missiles that knocked out Tails. As an avalanche then arrived, Robotnik and Knuckles took their leave in the Egg Mobile. As they did however, Knuckles noticed that Sonic prioritized Tails over the compass, which Robotnik regarded as a weakness.

Later, using a Ring, Robotnik and Knuckles traveled to an island hundreds of miles away from Hawaii with some Badniks. There, Robotnik found a recess for the compass to fit into using his control glove. After then inserting it into the recess, a great undersea temple was revealed in front of them. Entering the temple, Robotnik and Knuckles found themselves in a great labyrinth filled to the brim with traps. After barely avoiding the first traps, which cost Robotnik most of his Badniks, Robotnik decided to work smarter by deploying some reconnaissance Badniks that he used to map out the labyrinth for them. Eventually arriving in the Master Emerald's chamber, Robotnik decided he had no further use for Knuckles as the latter proclaimed pride in their collaboration. Before he could taser Knuckles with his control glove however, Sonic arrived in-between them and the Master Emerald. While Robotnik was disgusted by Sonic's motivation, he nonetheless began sneaking up to the Master Emerald while Sonic and Knuckles were busy fighting each other. When Knuckles finally noticed Robotnik's attempt to take the Master Emerald though, Robotnik mocked Knuckles for his gullibility and lack of foresight as he called out Robotnik for betraying their friendship. Grabbing the Master Emerald, Robotnik proceeded to vanish in a flash of energy.

Robotnik soon after reappeared in the Mean Bean Coffee Café, where Stone had been apprehended by Wade Whipple. In his elevated state of power, Robotnik adjusted himself to his new abilities as he teleported around, quickly forcing Wade to surrender while freeing Stone. Stone proceeded to warn him that G.U.N. had the café surrounded, but Robotnik revealed that he had a solution to this. Heading outside, Robotnik faced Commander Walters, Tom, Maddie and a squad of G.U.N. soldiers. There, Walters told Robotnik that he was finished, as the government had seized all his assets. In response, Robotnik used his newfound powers to pull in G.U.N.'s arsenal and various other components from the environment, which he used to build the Giant Eggman Robot. Putting himself in control of the giant machine, with Stone as his co-pilot, Robotnik had the Giant Eggman Robot trample around Green Hills, forcing G.U.N. to retreat. Soon after though, Sonic and Tails showed up in the Tornado. Though frustrated by Sonic's constant returns, Robotnik decided to shoot him down with a missile barrage. Since Stone had yet to figure out the controls though, Robotnik did it for him, inadvertently electrocuting Stone in the process. Though Sonic and Tails slipped through the barrage, he did manage to catch Sonic with one missile. Knuckles then arrived, but Robotnik had his Giant Eggman Robot's hand deal with his attack when the echidna tried attacking him head on. Tails then tried shooting at Robotnik's Giant Eggman Robot with the Tornado's guns, but Stone managed to use robot's 'Stache Masher feature to make the Tornado crash. However, Robotnik was left alone when Sonic returned with the missile and directed it into the Giant Eggman Robot, which shook the machine enough to knock Stone out.

After sending his Badniks after Sonic, Tails, and Knuckles, who easily dealt with them, Sonic came up to the Giant Eggman Robot and challenged Robotnik himself. Refusing to let Sonic get the better of him, Robotnik began following Sonic out of Green Hills. When he needed a break though, which prompted Sonic to taunt him further, Robotnik responded with his plans to enslave humanity and conquer the multiverse before opening eye lasers on Sonic. Eventually, Robotnik caught up to Sonic as he was crossing a bridge, which he blew up with the Giant Eggman Robot's nose laser, sending a weakened Sonic plummeting down. As Robotnik gloated about his superiority to the grounded Sonic however, he discovered that he was all-seeing as well, which let him notice Tails break into the Giant Eggman Robot's cockpit. As Tails began confusing him with holographic images of himself, Robotnik took them all out with his powers. However, Tails soon told him that he was just a distraction. It was then that Robotnik discovered Knuckles nearby, who managed to punch the Master Emerald out of him. Without his powers, Robotnik's Giant Eggman Robot shut down, leaving, Tails, Knuckles, and the Master Emerald to slide out of the robot.

Recovering, Robotnik got to his feet and activated the Giant Eggman Robot's auxiliary power. Assuming control over his robot again using the manual controls as well, Robotnik had his machine walk towards a weakened Sonic as he went to retrieve the Master Emerald. Before Robotnik could step on Sonic with his Giant Eggman Robot's foot however, Tom and Maddie swooped by in a truck and picked up both Sonic and the Master Emerald. In response, Robotnik had his robot topple their truck and trap them within a ring of fire. As Robotnik brought his Giant Eggman Robot's foot down upon the trio, he thought he had finally gotten Sonic. Unfortunately for him, Sonic managed to transform into Super Sonic in the last moment with the Chaos Emeralds that fell out of the Master Emerald. In this form, Sonic stopped the Giant Eggman Robot's stomp and cut off its head, exposing Robotnik. As Robotnik tried talking Sonic into a truce however, he used his control glove in an attempt to punch Sonic with the Giant Eggman Robot's fists. Sonic, however, easily stopped the attacks and pierced the Giant Eggman Robot several times before tipping it over, leaving Robotnik to fall down with it. However, when G.U.N. swept the crash site, they were unable to find any trace of Robotnik, leaving his fate unknown.


Sonic the Hedgehog: The Adventures of Sonic & Donut Lord

When an energy surge occurred in Green Hills, Montana, Robotnik was sent there by the United States government to investigate the phenomenon. Upon arriving there, Robotnik sent out his aerial Badniks before interrogating the local sheriff, Tom Wachowski, about the phenomenon. When one of his Badniks detected an unknown lifeform however, which turned out to be an alien anthropomorphic hedgehog named Sonic, who had the power of super speed, Robotnik sent his Badniks out to secure him, intend on learning the secrets of his power. As Tom tried to reason with Robotnik that Sonic was not necessarily a threat, the doctor ordered his Badniks to blast Tom too if he got in the way.[2]

With Sonic and Tom on the run together, Robotnik eventually hunted them down in his truck. However, Sonic managed to destroy the vehicle and the Badniks that Robotnik sent after them. Beaten, but not out yet, Robotnik eventually cornered Sonic, Tom and Maddie on top of the Transamerica Pyramid in his Eggpod with his aerial Badniks. As Robotnik opened fire upon the trio however, he saw, to his slight surprise, Sonic push Tom and Maddie off the roof of the building before running after them and sending them to Green Hills with a Ring. Robotnik then began chasing Sonic in his Eggpod, following him through the Ring portals he made. After their chase having led them into Egypt, along the Great Wall of China, and through Paris, Robotnik cornered Sonic, Tome and Maddie in Green Hills. Announcing his intention to dissect Sonic and neutralize the "traitors" who had helped him, Robotnik was surprised to see Sonic stand up to protect Tom and Maddie, announcing that he would use his power to protect his friends instead of running away from now on. In the next instance, Robotnik was defeated when Sonic destroyed his Eggpod.[2]

Sonic the Hedgehog 2: The Official Movie Pre-Quill

At some point, despite seeing Agent Stone as a nitwit in comparison to himself, Robotnik created his manifesto specifically for him so that he, in case of Robotnik's absence, would be able to survive without him and turn himself into an instrument of science so that he could rebuild his glory on a massive scale.[3] Additionally, Robotnik had Badniks stationed in various locations, waiting for activation.[4]

Robotnik seeking food on the Mushroom Planet, from Sonic the Hedgehog 2: The Official Movie Pre-Quill.

While stuck on the Mushroom Planet, Robotnik reflected that despite being trapped on an uninhabited planet with no resources except for his Eggpod parts, no supplies, and no apparent way home, he declared he would "be home by Christmas". He also thought back on Sonic, believing him to think that he had defeated him and that he was no better than any other human. Determined to proved him wrong, Robotnik vowed he would survive. While scouring the Mushroom Planet, Robotnik also found a blue mushroom that proved edible. As he gathered more for sustenance while he could work on rebuilding his Eggpod, Robotnik found a cave full of them, Upon plucking one however, it would reveal an carnivorous and aggressive plant. Scrambling around, Robotnik would disturb more of these plants, which proved able to injuring him. However, Robotnik stubbornly refused to yield to these plants and snatched more mushrooms, which only unveiled more carnivorous plants that began to swarm him. Even so, Robotnik refused to die there. As he came face-to-face with an extra large carnivorous plant though, Robotnik refused to let it intimidate him and so used a wrist-mounted flamethrower he had made from his Eggpod to burn it to ashes. Robotnik then proclaimed as he left the cave that he would destroy anything that gets in his way on this planet and return to Earth to get revenge on Sonic.[5]


Sonic Drone Home

At some point, Dr. Robotnik created a self-aware Badnik capable of thinking for itself named Unit. This Badnik would work on carrying out Robotnik's desire for world domination until Sonic convinced it to follow its own passions.

Game appearances

Sonic Dash

In Sonic Dash, Dr. Robotnik was added to the game as a part of its promotional update for Sonic the Hedgehog, serving as one of the game's bosses. Dr. Robotnik himself was not visible, but the player could hear his voice, which was actually the same voice that the standard Dr. Eggman uses, while he piloted the Eggpod.


Allow me to clarify: in a sequentially-ranked hierarchy based on level of critical importance, the disparity between us is too vast to quantify.

— Robotnik describing his superiority to Major Bennington, Sonic the Hedgehog (film)

Robotnik is a malevolent human who has been described as "pure, unbridled evil"[6] and a "psychological tire fire". Usually, he comes across as an assertive and self-confident person who does not let his convictions waver in the face of others. However, his genius intellect makes him very narcissistic. Notably, he will declare himself the head of any operation he is involved on, voicing out his supposed superiority to those he comes across without hesitation or consideration, and viewing everyone else around him as inferior and basic. Arrogant and condescending, he thinks that the hardest thing about being "the smartest person in the world is that everyone else is stupid". He similarly prides himself on his intellect and refuses to acknowledge surprise, instead falling back on the excuse that his movements of surprise do not count since he is "expecting not to expect something." These traits mainly stem from Robotnik's own severe inferiority complex which originate from childhood neglect. As a result, he sees himself as an insignificant speck, and yearns for acknowledgment and recognition. This often results in him bringing up personal accomplishments in order to make himself feel superior.

Robotnik is also characterized by his quite eccentric behavior. This includes sudden mood swings, mimicking robotic noises and movements, using large and complicated words in conversations to describe a simple situation, and dancing wildly to his own scenarios when he believes he is alone.

Robotnik is not one who tolerates failure and is very quick to lose his temper when it occurs, which prompts his violent mood swings. Lacking any concern about morality and collateral damage to boot, Robotnik is willing to do whatever it takes to accomplish his goals, as evidenced by the numerous lethal measures he took to capture Sonic and get rid of anyone helping him, and the destruction he caused to San Francisco and the Great Pyramids of Egypt. Despite his claims of wanting to improve the Earth, he is happily aware that he is "evil" and thus wishes to achieve improvement the way he envisions it, having for example put a label on his lab's light switch that says, "evil lab". He also has a large chip on his shoulder about being bullied as a child and hates being reminded of how he used to be at the mercy of unintelligent brutes.

Robotnik has also an incredibly sadistic streak, seizing any opportunity to inflict pain upon other people, and relishing every second of it. Notably, he would happily talk about how he wanted to dissect Sonic and "see what makes him tick", and smile as he threatened to kill Tom while interrogating him and reciting the US Code.

An egomaniacal and sociopathic misanthrope, Robotnik often voices his distaste for humanity, viewing human beings as inefficient creatures of hubris and desire. Humans similarly bore the doctor to the state that he considers their lives meaningless and therefore he has no desire for having friends, which he is proud of not to have. Robotnik is similarly completely devoid of empathy for any lifeform, be they humans, animals, or those in-between, being unable to understand why Tom would risk everything to help Sonic, and hunting Sonic in order dissect him for his own scientific inquiries. As such, Robotnik hates everybody around him, although he is shown to (barely) tolerate Agent Stone, whom he compliments for his lattes, albeit very aggressively, and intellect.[3] Due to his arrogance and having a mindset based on science and computational thinking, Robotnik sees human society as a computer system and people as programmable toy monkeys, with his approach to both aspects being based science and how to methodically rewrite such "programs" in his own favor without regard for the moral implications.[3] Interestingly enough however, despite Robotnik openly stating that he would not miss Agent Stone during the San Francisco incident, he did create a stand-in of his lackey to keep him company on the Mushroom Planet. This may imply either that he does desire human company on some level, or that he just needs someone to abuse.

Owning to his hatred of humanity and being a staunch perfectionist, Robotnik values only robotics, which he sees as practical and functional since they always follow their programming and do what they are told. He is especially proud of his Badnik drones, which he displays affection for and praises them for being relentless and effective. In his own words, his machines are everything to him, and he considers them to be a part of the further evolution of mankind.

Over the course of his hunt for Sonic's power, Robotnik's sanity would degrade to the point where he became completely obsessed with obtaining Sonic's power by any means necessary, eventually becoming willing to place himself in life-threatening situations where he would fail to realize the danger until it was too late. After spending almost three months alone on the Mushroom Planet, his grip on sanity would degrade even further (despite his claims to the contrary), as he would talk to a stone as if it was a real person. Eventually, after spending over eight months on the Mushroom Planet, the prolonged isolation has had a significant negative effect on the doctor's psyche, with his sanity having nearly completely disintegrated, and losing what little control and restraint he had, acting completely erratic and psychotic.

Robotnik is also treacherous, which ultimately lead to his downfall; right after he managed to gain access to the Master Emerald, Knuckles, whom he betrayed for the Emerald, formed an alliance with Sonic and Tails and helped to deprive Robotnik of the Master Emerald.

Powers and abilities

Robotnik with his Badniks, from Sonic the Hedgehog (film).

Dr. Robotnik has a genius intellect, boasting five PhDs and an IQ of 300.[7] Growing up, he was a child prodigy, apparently being able to articulate formulas around the time Tom was an infant. In adulthood, his intellect has enabled him to create various types of highly advanced and revolutionary remote-controlled machinery and robot drones. He is so intelligent in fact that he was able to accurately determine Sonic's exact height, weight and entire skeletal structure based on nothing but a footprint of his, and determine and harness the power of Sonic's alien biology. He has also been expertly trained to spot tracks by the Native American Shadow Wolves. He is also multilingual, being able to speak at least English, Japanese and French. He also has keen vehicle intuition, being able to expertly pilot his Eggpod through the narrow streets of San Francisco at speeds compatible to Sonic's while taking accurate shots at Sonic.

Robotnik also has impressive survival skills. After being stranded on the Mushroom Planet, he was able to fend for himself with only a pack of salvaged scrap, his wrist device, and his intelligence for nearly three months. He also demonstrated great skill in setting booby traps.


Robotnik's glove controller, from Sonic the Hedgehog (film).

Dr. Robotnik wears a uniquely designed controller on the glove of his left hand; with a few buttons presses and finger-thumb movements, he is able to program and command his technology, or secretly and non-verbally control his machines. This controller also has standard internet functions. A variation of this device was later incorporated into the doctor's flight suit, which sported a radio recorder and a date counter.


Robotnik's transformation, from Sonic the Hedgehog 2 (film).

By harnessing the power of the Master Emerald, Robotnik can attain a higher state of being. Described as all-powerful, all-knowing, and all-seeing in this form, Robotnik possesses the ability to turn thought into reality while in this state, allowing him to perform various reality-bending feats that include, but are not limited to, telekinesis, heighted senses, flight, energy manipulation, teleportation, and technokinesis,


Robotnik is shown to have low durability, as a single punch to the face from Tom was enough to stun him long enough for Tom to escape with Sonic.

Robotnik also has a massive, but very fragile ego. As his hunt for Sonic continued, he became more unhinged with every defeat, until he was driven completely insane from his plans being foiled.

After his first defeat at Sonic's hands, Robotnik has also developed an obsessive hatred of the hedgehog which can be used against him, as seen when Sonic got the doctor to focus all of his attention on him by taunting him.

You're an astonishing little creature! It'll be fun to take you back to the lab for a litany of invasive exploratory procedures. Any last words?

— Dr. Robotnik, Sonic the Hedgehog (film)

Sonic the Hedgehog is Dr. Robotnik's arch enemy whom he loathes with a passion. Robotnik resents Sonic in particular because he represents the youth and happiness the doctor himself never had.[8]

Originally shocked upon seeing Sonic in person, Robotnik soon came to see Sonic as a specimen he was eager to dissect and examine for his own benefits. However, after discovering the true potential of Sonic's abilities and the hedgehog's juvenile behavior, he saw Sonic as both his key to world domination, as well as a defiant, smart-mouthed teenager. Robotnik's resentment of Sonic likewise grew throughout his first encounters as he was continuously bested and embarrassed by Sonic, whose attitude, irritating jokes and self-confidence that rivaled Robotnik's own ego. He was likewise greatly irritated by Sonic's mocking jokes and remarks towards him, seeing his confidence as a fool's substitute for intelligence and believing that he should not stand a chance against his intellect. By the time of his first personal battle with Sonic, Robotnik was determined to defeat him no matter the cost and seize his power for himself, being willing to literally destroy anything and anyone who got in his way. Regardless, he did have a small measure of respect for Sonic, having called him an "astonishing little creature".

After stewing in hatred of Sonic for eight months on the Mushroom Planet, Robotnik has made it one of his foremost goals to get revenge on Sonic by destroying him, a goal of which is almost on the same level as his desire for conquest of the multiverse and the enslavement of the human race. He was also not afraid to personally stand in front of Sonic and taunt him with threats directed at his foster family. However, his obsession with Sonic has also led to becoming Robotnik's greatest weakness: his desire to defeat Sonic and show his superiority to him in spite of the hedgehog's taunts and jokes tend to make him so obsessively focused on him that he fails to realize other threats to him, which ultimately leads to his own defeats.

After his first conflict with Sonic, Robotnik has grown to fear the hedgehog - or at least his power, as evidenced by his uneasiness at the Labyrinth when Sonic prepared to fight.

Agent Stone

While Robotnik appreciates what Agent Stone does for him at times, he is shown treating him with nothing but contempt most of the time, even being severely peeved when Stone thought to check on him (after Tom punched him in the face) instead of going after Sonic and Tom. Later on, when Stone comments on Tom and Sonic escaping his drones, Robotnik chides him by saying he will not miss him when he and other humans are replaced with machinery. After losing all his sanity on the Mushroom Planet, Robotnik created a stand-in of Agent Stone from a stone to keep him company, though throwing and mocking it as he did with his lapdog. Also, despite Stone's firm loyalty towards him, Robotnik only sees him as person to push around or take advantage of. At some points though, there is a certain bond between; while Stone himself admires Robotnik, the doctor loves his Austrian goat milk latte. After his return from exile, Robotnik appeared more appreciative of Stone and treated him substantially better than before. Also, in addition to having Stone accompany him as his co-pilot onboard the Giant Eggman Robot, Robotnik would eagerly listen to his praise, although he did so with apathy while recognizing Stone as a bootlicker. He also displays at least a sliver of care for Stone's well-being, as evidenced by his concern when Stone was knocked unconscious.

While Robotnik sees Stone as inferior to him in every way, he nonetheless recognizes him as practically a genius in comparison to regular humans. Seeing Stone as doomed without him, Dr. Robotnik created a contingency plan for Stone in the form of his manifesto so that Stone could survive in his absence. However, rather out of care for Stone, it was more on the grounds of allowing Stone to rebuilt himself into a tool of pure science so that he could rebuilt Robotnik's own glory on a massive scale that he would provide Stone with such instructions.[3]

Tom Wachowski

Who the hell do you think you are?!

— Dr. Robotnik, Sonic the Hedgehog (film)

Upon meeting Tom Wachowski, Robotnik immediately viewed him with the same contempt he holds for humanity: a nobody who thinks they are something special because of their own personal achievements. As a seemingly average small-town police officer, Tom represents the "mediocrity" of mankind that Robotnik so despises, prompting Robotnik to consider him an enemy. Robotnik similarly treats all of Tom's achievements lightly. However, it also leads to him greatly underestimating Tom's intelligence and cunning. He would also take a greater disliking towards Tom due to the latter's uncooperativeness and how he outsmarted him in their first meeting. This was further bolstered when Tom punched him in the face, an indignity he had suffered only once before, and successfully helped Sonic escape him in their first encounter. As Tom and Sonic continued to elude and humiliate him, his vendetta for Tom would grow. By the time he cornered Tom and his associates on top of the Transamerica Pyramid, he would hold a deep-seated hatred for Tom, and anyone associated with him, second only to his hatred of Sonic, and wants him to die as much as he wishes for Sonic.

Knuckles the Echidna

When he first ran into Knuckles the Echidna, he saw as a threat. When he realized that he also wanted revenge on Sonic however, he would eagerly help get him to Earth, in exchange for getting him off of the Mushroom Planet. While Robotnik would (sarcastically) declare himself and Knuckles best friends "forever and ever" after that, his true intentions was to use Knuckles to humiliate Sonic. When he later found out about the existence of the Master Emerald, he used Knuckles as his unknowing lackey to take him to the Emerald so he could seize its power for himself.

When it came to his treatment of Knuckles, Robotnik treated Knuckles like a pet, such as when he suggested sticking his head out from his Egg Mobile. Also, while Robotnik would pretend to be polite and benevolent in his presence, he considered Knuckles to be an imbecile. He also took no consideration of Knuckles' unfavorable opinion about his lack of loyalty towards Agent Stone.

When on the cusp of acquiring the power of the Master Emerald, Robotnik remorselessly betrayed Knuckles by showing his true intentions while mocking the echidna with a "lesson" about the latter's own lack of intellect and how friends make others weak. From then on, with the echidna having befriended Sonic after the scientist's betrayal, Robotnik and Knuckles would view and treat each other as enemies.

Miles "Tails" Prower

You can't outsmart me! I'm the outsmarterer!

— Dr. Robotnik, Sonic the Hedgehog 2 (film)

Although Robotnik never directly interacts with Tails, it is apparent that he views the fox in the same light as his other enemies. However, he does acknowledge Tails' intelligence (which he sees as vastly inferior to his own), being impressed by the fox's maneuver to save Sonic and evade Knuckles.




You are history!

— Dr. Robotnik, Sonic Dash

Dr. Robotnik is an event-exclusive boss that appeared in Sonic Dash in early 2020 to promote the then-upcoming Sonic the Hedgehog film. In this event, he replaced Dr. Eggman and Zazz as the sole boss in the game, though he did make use of Eggman's voice lines.

Robotnik could be fought in any Zone with any character. To trigger the battle, the player had to hit a Spring with an orange screen and a black Eggman Empire symbol on it. A short while after the playable character landed on solid ground, Robotnik would appear in his Eggpod and hover on their left, introducing himself and starting the fight.

Boss guide

The boss battle was divided into three phases. During the first one, Robotnik would position his Eggpod behind the player and fire Badnik-like missiles from his ship towards the playable character, which the player could avoid by making a well-timed jump or by moving to the sides. After firing a total of nine shots, Robotnik would proceed to the second phase of the fight, in which he would fly ahead of the player, from where he would drop Bombs on the road in different formations. Like with the missiles, the player could avoid the Bombs by moving to the sides or by jumping over them. Once the player approached a section with three Springs, Robotnik would mock the player and fly away.

In the third phase, after touching the Springs, the playable character would be on the air, right behind Robotnik. The player then had to tap the green target reticles that appear, which would make their character attack the Eggpod. After successfully landing three hits, Robotnik would be defeated and the player would receive points. If the player missed a hit though, the doctor would escape without the player receiving points.

Robotnik would get more aggressive the more the player progressed in a single run. While the battles would be much shorter, the doctor would fire his missiles and Bombs at a much faster pace, not giving the player much time to reach. In the third phase, the green targets would also move much faster, increasing the chance the player misses a hit. However, if Robotnik was successfully defeated, the player would be awarded more points.

On 29 April 2019, the first look at Jim Carrey's rendition of Dr. Robotnik was leaked, a day before the first trailer for Sonic the Hedgehog got released. Fans and media reacted mostly with surprise at Robotnik's first look.[9][10] The following day, the first official trailer for the film was released, as well as its official poster. The two received mixed-to-negative reactions from the fans and media, mostly because of Sonic's initial design. However, Jim Carrey as Robotnik received mostly positive reactions, with some fans remarking that he is channeling his '90s era portrayals in a good way, and also that his appearance at the end of the trailer was more similar to Robotnik's game counterpart.[11][12][13]

On 10 January 2021, Jim Carrey won an award at the Critics' Choice Super Awards in the category "Best Villain in a Movie" for his portrayal of Dr. Robotnik in the Sonic the Hedgehog film.[14]


  • Instead of mocking his appearance, Robotnik's nickname, "Eggman", is derived from the fact that his standard Badniks resemble eggs.
  • Robotnik seems to have a fondness for classical music, as he whistles "Ride of the Valkyries" when summoning a Badnik in the Wachowski residence in the first Sonic the Hedgehog film.
  • In one scene in Sonic the Hedgehog, Robotnik can be seen playing "Where Evil Grows" by The Poppy Family on his personal music playlist called "Tunes of Anarchy". Other songs and playlists seen include, "Robotnik Rhythms", "Everybody Wants to Rule the World", "Soulful Chamber Music of Oppression", "Nuclear Tempos of Rhapsody", "Dinner For One", "Acoustical Tempo for Tyranny", "Heavy Metal Bombing Over Babylon", "Obscure 1970's Canadian Jams", and "Crush 40".
  • In his appearance in Sonic Dash, Robotnik's voice clips are the same as Dr. Eggman's. Thus, he is voiced in the game by Mike Pollock instead of Jim Carrey.
  • Robotnik is the first character in the Sonic the Hedgehog film series to swear.
  • According to Sonic the Hedgehog 2: The Official Movie Novelization, Robotnik's middle name is Gerald. This is the first name of his game counterpart's grandfather, Gerald Robotnik.[15]
