You know, I won't miss you when you're gone. Human beings are stupid and unreliable, and I care very little about them. But my machines are diligent, relentless. THEY'RE EVERYTHING TO ME!

— Dr. Robotnik, Sonic the Hedgehog (film)

Doctor Robotnik[1] is the main antagonist of the Sonic the Hedgehog film series produced by Paramount Pictures. He is an evil and misanthropic human scientist who plots to capture Sonic the Hedgehog and harness his powers in order to take over the Earth.

Originally a United States operative with a revolutionary robot army at his disposal, Robotnik was sent to investigate a blackout originating from Montana. What he found, however, was an extraterrestrial alien named Sonic with incredible powers. After he escaped him, 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 sat his sights on much bigger goals. During his attempt to capture Sonic however, he was defeated by the alien and banished to the Mushroom Planet, where he would plot his return.


Dr. Robotnik is an average-sized human. He originally possessed dark brown (almost black) hair, 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 and black sunglasses. 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 color, his nose gained a notable pinkish-red sunburn, and the sleeves of his suit had been torn off.


Film series


Growing up an orphan, Robotnik came to resent family. While attending school, Robotnik was harrassed 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. Instead of reporting him to the principal though, 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.

Sonic the Hedgehog

When an electromagnetic pulse of unknown origin caused a blackout all over the Pacific Northwest. Robotnik was assigned by the United States to quickly and quietly determine and resolve the cause of the phenomenon, if proven hostile. 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 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 rebuked 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 and had Stone bring Sonic's quill along.

Occupying the Green Hills Sheriff's Department, Robotnik and his agents overheard a conversation between Tom and Wade. 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 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 as well. 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 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 berated 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 nummerous 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.

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 "be home by Christmas" and sat out on a journey across the Mushroom Planet with his stone companion.

Sonic the Hedgehog 2


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 suprise, 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. Annoucing his intention to dissect Sonic and neutralize the "traitors" who had helped him, Robotnik was suprised to see Sonic stand up to protect Tom and Maddie, annoucing that he was 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]

Game appearances

Sonic Dash

Dr. Robotnik, from 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 is not visible, but the player can hear his voice (which is actually the same voice clips that the standard Dr. Eggman uses) while he pilots the Eggpod.

The boss battle begins with Dr. Robotnik following the playable character. He will then fire white, egg-like rockets down the lanes. After firing a total of nine shots, he will position the Eggpod in front of the playable character and drop Bombs on the lanes. After completing this phase, the player has to jump onto some Springs. While in the air, the player has to hit Robotnik's Eggpod at the right time with a Homing Attack by taping the screen when two green cursors overlap. After three hits, Dr. Robotnik and his Eggpod will be defeated.


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

Robotnik is a malevolent human who has been described as "pure, unbridled evil"[3] and a "psychological tire fire". Usually, he comes across as an assertive and confident person who does not let his convictions waver in the face others. However, his genius intellect makes him very narcissistic. Notably, he will declare himself the head of any operaiton 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 suprise, instead falling back on the excuse that his movments of suprise 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, mimicing 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 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.

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. Interestingly enough however, despite Robotnik openly stating that he will not miss Agent Stone, 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.

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 degraded even further (despite his claims to the contrary), as he would talk to a stone as if it was a real person.

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.[4] 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 Sonic-level speeds while 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.


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 button presses and finger-thumb movements, he is able to program his Badniks and deployed them from his truck to search for his targets, or secretly and non-verbally dispatch reconnaissance drones. This controller also has standard internet functions. A variation of the device was later incorporated into the doctor's flight suit, which sported a radio recorder and a date counter.


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.


Sonic the Hedgehog

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.[5]

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. He was likewise greatly irritated by Sonic's mocking jokes and remarks towards him, seeing his cofidence as a fool's substitude for intelligence. 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".

Agent Stone

While Robotnik appreciates what Agent Stone does for him at times, he is shown to treat him with nothing but contempt, 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.

Tom Wachowski

Robotnik fighting Tom, from Sonic the Hedgehog (film).

Who the hell do you think you are?!

— Dr. Robotnik, Sonic the Hedgehog (film)

Upon meeting Tom Wachowski, Robotnik immediaely viewed him with the same contempt he holds for humanity. As a seemingly average small-town police officer, Tom represents the "mediocrity" of mankind that Robotnik so despises, prompting Robotnik to greatly underestimate his intelligence and cunning. However, he would take a greater disliking towards Tom due to the latter's uncooperativeness. This was further bolstered when Tom punched him in the face, an indignity he had suffered only once before. 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.




"Oh, my babies! Look at what came out of my egg sack! You know what I love about machines? They do what they're told, they follow their programming! They don't need time off to get drunk and put the boat in the water!"
—Dr. Robotnik, Sonic the Hedgehog (film)
"Whatever this creature is, it's our job to secure it, neutralize it, uncover the source of its power. And if it resists... we take it apart, piece by piece, see what makes it tick."
—Dr. Robotnik, Sonic the Hedgehog (film)
"Eeny, meeny, miny... Mayhem!"
—Dr. Robotnik, Sonic the Hedgehog (film)
"What do I look like, an imbecile? Of course I want a latte. I LOVE THE WAY YOU MAKE THEM!"
—Dr. Robotnik, Sonic the Hedgehog (film)
"Confidence! A fool's substitute for intelligence."
—Dr. Robotnik, Sonic the Hedgehog (film)
"I don't have to tell you how many scientific breakthroughs have been made possible by animal testing. You're being very selfish."
—Dr. Robotnik, Sonic the Hedgehog (film)
"Why would you throw your life away for this... thing? That's why I don't have friends. Next thing you know, you're somebody's best man, they want to have the wedding out of town... Like nobody has anything better to do! Anyway, where were we? Oh, right-you were about to die."
—Dr. Robotnik, Sonic the Hedgehog (film)
"Here's the sitch: uninhabited planet, no resources, no supplies, no apparent way home... A lesser man would die here. I'll be home by Christmas."
—Dr. Robotnik, Sonic the Hedgehog (film)


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.[6][7] On 30 April 2019, the first official trailer for the film was released, as well as its official poster. The trailer 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.[8][9][10]


  • Instead of mocking his appearance, Robotnik's nickname, "Eggman", derives from the fact that his 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 one scene, 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 only character in the Sonic the Hedgehog film to swear.
  • When confronting Tom in the Wachowski household, Robotnik threatens to kill him and expunge all records of him, effectively erasing him from existence. Ironically, after his defeat and banishment, Robotnik is the one who ends up erased.
