Sonic the Hedgehog
Voiced by: Ben Schwartz, Benjamin L. Valic (Baby Sonic), Taishi Nakagawa (Japanese dub), Luis Arturo Villar (Latin-American Spanish dub), Christian Hedlund (Swedish dub), Manolo Rey (Brazillian Portuguese dub)
An anthropomorphic blue hedgehog gifted with super speed hailing from a mysterious parallel world from Earth. Having escaped the planet as a child to avoid being hunted by those who desired his power, he lives on Earth in and around the sleepy town of Green Hills, Montana. However when his super speed inadvertently causes a massive EMP that disables all electrical power in the surrounding area, he catches the attention of the government and one particularly peculiar scientist. Caught in a bind when his portal rings go missing, he comes to rely on the assistance of a local sheriff that he has seen around the town to recover them.
- Accent Adaptation: In the Latin American Spanish dub, Sonic speaks with a slight undescritable European accent, probably to make him sound more alien compared with the rest of the human cast. This is quite justified in this case, as his voice actor, Luis Arturo Villar, is Mexican of Czech origin.
- Achievements in Ignorance: During the highway chase in being pursued by Robotnik's convoy, Sonic accidentally trips into a ball and uses his Spin Attack for the first time, having no idea what he did, how he did it or why it worked. When it comes time for the final confrontation, he's understood how it works and how to use it to great effect, repeatedly slamming into Robotnik's ship before the doctor can even react.
- Adaptational Angst Upgrade: Downplayed. In the games, he is frequently portrayed as being a fairly popular figure, beloved by the little animals he rescues, always with a large group of friends and a boundless source of confidence. Here, he spent ten years of his childhood in almost total social isolation, and desperate for companionship, even though he masks that with his usual snarky attitude and playful charisma. Not to mention that, at least in the videogames, he has no backstory to speak of.
- Adaptational Nice Guy: Downplayed. While Sonic was by no means a Jerkass in the games, he often displayed a cocky attitude that the film leaves out almost entirely.
- Adaptational Superpower Change: In the games, Sonic has always been associated with the wind. In the movie, his speed conjures electricity. That said, he does learn how to manipulate wind somewhat in the final chase with Robotnik, utilizing his speed to create a localized sand tornado while in the desert.
- Adaptation Dye-Job: Rather than the peach-colored arms he has in the games, Sonic instead has blue arms like his Sonic Boom counterpart.
- Age Lift: In the games, Sonic is 15. According to director Jeff Fowler, this films version of Sonic is either 13 or 14.
- Agony of the Feet: The first pair of shoes he's shown wearing are falling apart, held together with duct tape and with large holes in the bottoms. When Maddie removes Sonic's shoes, there are also large holes in his socks, and Maddie's niece Jojo notes that Sonic's feet must really hurt from all the running he does. Jojo fixes this problem by giving Sonic a pair of brand new shoes, and some fresh socks, that closely resemble his game counterpart's. It's also a plot point, as part of why Robotnik is able to realize what he is, as the resulting footprints allow show his strange feet and give Robotnik a lot of details about him.
- Alien Among Us: Upon fleeing his home planet and ending up on Earth, Sonic spent 10 years hiding in Green Hills and spying on its citizens, with Crazy Carl being at least aware of his existence. After tagging with Tom, he still keeps a low profile and wears a disguise when at the bar and is hidden in a bag when taken to San Francisco.
- Aliens Speaking English: It isn't explained why he can, unless he spent his years listening to humans and Longclaw talking to him was Translation Convention.
- Ambiguous Disorder: Sonic has a glaringly obvious hyperactivity and performs many moves and gestures to avoid standing still. Due to the loneliness he endured for 10 years, he also compulsively talks to himself—which he is aware of—and plays an entire game of baseball while pretending to be several players at once.
- Amusing Alien: In this version, Sonic is explicitly an extraterrestrial and treated as such, albeit responsible for much of the film's humor thanks to his fun-loving personality and a very hyperactive disposition.
- Anthropomorphic Shift: Sonic was more humanoid looking than his normal Funny Animal appearance in the original promotional material. This extended to his teeth being more human-esque than usual and him having fingernail-esque claws on his non-gloved hands. Post-fandom backlash, and Paramount made him look far more cartoony and expressive to keep him closer to his origins, but still looks slightly more humanoid (having visible shoulders, smaller hands, a small-but-visible neck, and slightly-pronounced calf muscles).
- Badass Adorable: His redesign in the second trailer has made him look infinitely more adorable, as he himself points out in the page quote. Even more so when he was a baby, but still fast enough to run through his entire hometown in less than two seconds.
- Beware the Silly Ones: Sonic pretty much acts like a hyperactive teenager with an insanely short attention span, but as seen in several scenes, when he has to deal with a serious threat, he can become crafty and downright dangerous.
- Blessed with Suck: It's noted in the second trailer he was constantly hunted down on his home planet due to his powers. This led him to flee to Earth, only to find himself chased by Robotnik (and by extent, the United States government) for the same reason.
- Blood Knight: While not as prominent as his game counterpart, there's still shade of this trait as Sonic loves a good fight due to him watching too many action movie. Best shown when he face the thugs in the bar or when he insist to take down Robotnik's drone despite his rather weakened condition as Tom take him away.Sonic: Aww, don't tell me that's all you got. I'm just getting started! Let me know if you want to go round 2 with the blue!
- Blue Is Heroic: Sonic is a blue hedgehog who is the hero of the movie. Contrast with Robotnik, who wears black and later red.
- Came Back Strong: After he gained his Heroic Second Wind, the electricity that powers him increases so much that he's just pulsating with power.
- Character Exaggeration: Sonic's quirkiness and energy level is ramped up. He's depicted as barely keeping still in the film, while his game counterpart is more laidback.
- Cheerful Child: As a kid back on his homeworld, before he was separated from Longclaw. He's still relatively cheerful on Earth, but he does lay on the snark from time to time.
- Comically Missing the Point: He calls Maddie "pretzel lady" because he observed her practicing yoga, which led him to believe she had no bones.
- Composite Character: He has shades of this in both design and personality:
- Following the redesign, Sonic's design has struck a balance between his Classic, Modern, and Boom designs. He has the height, larger torso, and attire from the Classic design in addition of being a little bit younger, the green eyes, darker blue fur colour, and quill length of the Modern design, and the blue arms, scruffy/bushy quills, and visible neck and shoulders from his Boom design. He also maintains his general expressiveness from all three designs. Additionally, his trainers appear to be a hybrid of both his iconic Power Sneakers and the Soap Shoes from Sonic Adventure 2.
- Personality-wise, he's mainly his Modern self: being cocky, cool, and not being one to take most things seriously, but simultaneously knowing when to step up once things truly get dangerous. However, he also likes to horse around and be silly; much like his Boom and Adventures of Sonic the Hedgehog incarnations.
- In regards to his abilities, along with his speed he also has electrical powers which are tied to his emotions, specifically his anger. The only character in the Sonic mythos who has elemental powers that are fueled by emotions is Blaze the Cat.
- Conjoined Eyes: Subverted. His eyes are separate, instead of having his eyes close enough to touch. Despite not looking like it at first glance: there's a tiny white patch of fur between his eyes to give the impression of the aforementioned closeness.
- Delinquent: Trailers and promotional material describe him as a juvenile delinquent. The reality of the movie is less so: he's a spunky, hyper-active character but it's mostly down to his status as a loner living on the outside of society, with only himself as company. Otherwise, he has everyone's best intentions in mind and is typically nice.
- Disney Death: In the climax of the movie, it appears Robotnik managed to kill Sonic in Green Hills. However, when Tom declares he was his friend, he gains the willpower to come back at full strength and beat the villain.
- Does Not Know His Own Strength: Sonic is clearly caught off guard by how his lone running around a baseball field caused the enormous EMP-like phenomenon that caused a blackout across all of the Pacific Northwest. He also admits he has no idea how he could hit one of Robotnik's vehicles so hard with a spin attack to crash it.
- Does Not Like Spam: He doesnt like mushrooms, and dreads having to retreat to Mushroom World to escape danger and villains. This is possibly a friendly jab at either his longtime rivals from the Console Wars, or a sly reference to his own series' Mushroom Hill Zone.
- Drives Like Crazy: Judging by how wrecked Rachel's car was upon arriving to the tower where his bag of rings ended up, it's certainly safe to say he does this to a T. When fleeing Robotnik along with Tom on a highway, he pulls some equally reckless moves behind the wheel, because he was reading the instructions and driving at the same time.
- Emotional Powers: This is how his offensive abilities actually work. His body starts producing blue lightning whenever he starts feeling anger, extreme joy, sorrow, etc. - while his eyes would turn from green to glowing blue. The first example of this power being shown was during the baseball scene where Sonic realizes that he is completely all alone and all the stress of being alone on Earth for 10 years causes Sonic to emit a powerful electromagnetic blast that caused a blackout across the Pacific. Come the end of the film, The Power of Friendship causes Sonic to consciously bring out his full power, and it is implied that he has learned to control this.
- Exposed Extraterrestrials: Sonic's only choice of clothing in his life is a pair of white gloves and his sneakers. Even when disguised at the bar, his outfit doesn't have pants. He is aware of it somewhat, as he mentions to Tom that he wears no pants.
- Fast as Lightning: He has the ability to generate lightning when he runs similar to The Flash. It's because of this he causes a huge blackout across the entire Pacific Northwest.
- Five-Finger Discount: Implied, given his Super Speed, and the fact that he can't exactly walk into a store and buy food, souvenirs, etc. While the movie doesn't linger on this point, Sonic presumably stole most of what he needed to survive.
- Fragile Speedster: Zigzagged. While renowned for his supersonic speed, Sonic's small height and lithe figure keep him from hurting a huge, burly biker at a bar even with a bottle. There's also the fact that being in close-proximity to some explosions knocks him out cold, even to the point of nearly dying. However, this was due to Sonic not understanding his powers or how they work, but he eventually unleashes his full strength once he gains the will to actively fight Robotnik in the climax, hitting his ship with enough strength- while powered by conducted electricity-to send him flying through a portal and send him packing into the Mushroom Planet.
- Friend to All Children: He quickly becomes attached to Tom's niece Jojo, after she gives him new shoes, aka the traditional red sneakers he's always been featured with.
- Friend to All Living Things: His first scene as a teenager has Sonic saving a tortoise from being run over by a truck and treating it to a high-speed run with him.
- Furry Reminder: What are hedgehogs known for? Sonic occasionally curls up into a spiky, non-rolling ball, for example, to hide by blending in with other sports balls.
- Gass Hole: A downplayed example since it only happened twice in the film. But after he eats up some chili dogs during the bar brawl scene, he is seen burping and then letting out a loud fart much later on.
- Glass Cannon: Much like in the games, Sonic's fleet feet are offset by relative physical fragility. He is knocked unconscious by a small bomb from one of Robotnik's machines, and later is almost killed by a single blast from the laser cannon on Robotnik's hovercraft.
- Glowing Eyes: Sonic's eyes shift from green to glowing bright blue when his body is conducting electricity. His eyes flash for a moment in the first trailer (as electricity momentarily travels along his body), and are shown to full-on glow in every trailer afterward.
- Go Mad from the Isolation: Downplayed. While not insane, Sonic has clearly gotten desperate for meaningful contact after more than a decade of being alone. When the film begins, he's been living in a cave on Earth for ten years, and his extended isolation has taken a toll on his mental state. He pretends to have conversations and activities by using his Super Speed, and also pretends to have friends by spying on the residents of Green Hills; he even acknowledges at one point that his loneliness has driven him a "bit crazy". Sonic finally hits his breaking point while playing a baseball game by himself; he scores a home run, cheers for himself, and looks over at the stands to see them completely empty. The resulting frustration and sorrow Sonic feels is what leads him to trigger the EMP that knocks out power across half the country.Sonic: I really am alone... all alone. Forever.
- Happily Adopted: Was raised by an owl called Longclaw and is essentially adopted by Tom and Maddie at the end.
- Hates Being Alone: He enjoys his solo life on Earth, but he hates feeling lonely and longs for true friends. While Sonic follows Longclaw's instructions to remain out of sight, he's gotten a little desperate for someone to talk to, having been alone for 10 years since he came here.
- Heroes Love Dogs: While Sonic, at first, resents Ozzy because Tom considers him his best friend, once they meet, the hedgehog quickly warms up to the dog.
- Heroic Second Wind: In the final confrontation with Dr. Robotnik, Sonic is struck by an explosion that knocks him out and it appears he's either dead or unconscious. As Robotnik mocks Sonic, Tom jumps in to fight him, but is knocked off. Robotnik then mocks Tom for trying to risk his life for "this... thing" and Tom angrily corrects him, stating that thing is named Sonic, and he was his friend. Sonic, who had spent the entire movie believing he would live alone without any friends, suddenly opens his eyes as blue sparks erupt about his body, and immediately challenges Robotnik to round 2 using his innate power.
- History Repeats: Sonic left his home world to avoid being hunted by those who would like to harness his power. Ten years after moving to Earth, Dr. Robotnik begins to hunt him down for the same reason, to which Sonic resolves to reluctantly leave Earth for the Mushroom World.
- I Choose to Stay: After getting back his bag of rings in San Francisco, he hesitates before escaping to another world- and is stopped from doing so by Robotnik. After beating him, Sonic decides to stay in Earth and gets adopted by the Wachowskis.
- I Just Want to Have Friends: Hiding from literally everyone after getting to Earth has left him incredibly lonely. Unsurprisingly, he becomes instantly attached to Tom when he finally shows himself. He doesn't even decide for himself that Tom is his friend, keeping this unfulfilled wish as the last item on his bucket list. Cue Tom protecting Sonic's believed-to-be-dead body from a callous Robotnik, declaring Sonic to be his friend, and then...
- Inexplicably Awesome: It's never revealed how or why Sonic has his powers. We're only told that Sonic must keep those powers from people who would abuse them.
- Innocent Aliens: Sonic is, at his core, a nice and good-hearted fellow who wants nothing but making friends. Even though his bucket list includes stuff as "starting a bar brawl", he sees it as an innocent form of living life to his fullest before he leaves Earth.
- Innocently Insensitive: He causes a fair amount of unintentional grief towards Tom during their adventure, though he improves later on.
- Intelligent Gerbil: Sonic is an extraterrestrial being who happens to resemble a bipedal hedgehog. However, as analysed by Maddie, his physiology is completely alien and different from any animal on the planet.
- Interspecies Adoption: Before coming to earth, the hedgehog's primary caretaker and parental figure was an owl named Longclaw. By the end of the movie, he gets adopted by his human friends, Tom and Maddie.
- Interspecies Friendship: He develops one with Tom Wachowski throughout the movie, and one of the items in his to do list is "make a real friend". The sheriff is probably the first friend he's had in his entire life.
- Keet: He is, in his own words, a "little ball of super-energy". And the movie proceeds to show him a highly energetic and hyperactive hedgehog who will do about anything to avoid standing still.
- Kid Hero: Described as a juvenile delinquent and has a child-like maturity to him. Jeff Fowler confirms here that Sonic is either 13 or 14 years old in the movie — which makes him even younger than his canon age of 15 in the games.
- Kiddie Kid: Downplayed, his cave features some toys meant for children slightly younger than him and he tends to be more emotionally vulnerable than most children his age. This may be justified given his years living in isolation may have resulted in some stunted development.
- Klingons Love Shakespeare: Sonic has become quite taken with some of Earth's entertainment. One of his most prized possessions is his stack of The Flash comics and his favorite movie is Speed- and he considers Keanu Reeves to be a "national treasure".
- Literal-Minded: When Tom states that a bucket list is about things you want to do before you "kick the bucket", Sonic assumes he needs to actually kick a bucket, which he excitedly admits he's never done before.
- MacGuffin Super Person: In the source material, Sonic's blindingly fast and remarkably powerful, but without a Chaos Emerald in hand, his skillset doesn't go much farther than that. Here? He's a living reactor of theoretically infinite power, to the point where a single quill's charge is sufficient to power robots and armaments well beyond anything else in modern society.
- Motor Mouth: Owing to his hyperactivity, Sonic talks a lot. When Maddie gets surprised to know that he can talk, Tom retorts that Sonic doesn't know when to stop and can be heard talking behind a closed door through the entire, meaningful conversation between the Wachowskis. He can't shut up even when hiding in the attic from Robotnik's robots, much to his own dismay.
- My God, What Have I Done?: Has this reaction immediately after losing control of his frustration, and thus causing the EMP blast.
- Mysterious Past: Save for what he tells us, we never really know who gave birth to him or why he has the speed power in the first place. Longclaw has been his parental figure up till he escaped to Earth and he's had the power for as long as he's known. That's pretty much all we get.
- Nice Guy: Maybe even more so than his gaming counterpart; while gaming Sonic has a good heart and an easy going personality, he also has something of an attitude. In the movie, he's much more cheerful and outwardly friendly to all creatures, most likely due to his want of friends, and will put his life on the line to protect others.
- Nice Hat: One of his most prized possessions is a red hat that he considers taking with him when he first attempts to leave Earth. Later, when disguised at the Piston Pit bar, he wears a cowboy hat.
- Nice Job Breaking It, Hero!:
- Sonic's running ends up causing an EMP-like sonic boom to knock out all power in the Pacific Northwest, resulting the US military hiring Robotnik to capture him.
- It's also the reason how he ended up on Earth in the first place, since he couldn't resist speeding around on his home planet despite knowing people, in this case the Echidna tribe, were after him for his power. They manage to track him and he leads them right to where Longclaw and he were staying, forcing them to run and her sacrificing herself to protect him as he crossed a ring into Earth.
- Nice Shoes: Although he did not wear them in his initial design (having generic red PUMA ones), Sonic's unmistakable red and white trainers (which are still PUMA shoes) are brought back in the redesign. In the movie, he wears a pair of generic sneakers until he arrives in San Francisco where they are shown to be extremely worn down due to his speed. Maddie's niece then gives him his trademark red and white sneakers.
- The Nicknamer: He spent his life on Earth eavesdropping on Tom and Maddie Wachowski, giving them the nicknames "Pretzel Lady" for Maddie's dexterity in practicing yoga, and "Donut Lord" for Tom because of his penchant for eating donuts (and talking to them). And of course, he calls Robotnik "Eggman" because his drone army shares a white color scheme and ovoid shape which makes them resemble eggs.
- Not So Similar: Both he and Robotnik grew up orphans, with no friends, and a burdensome power (Sonic his Super Speed, Robotnik his Super Intelligence). That's where the similarities end; whereas Sonic is a Nice Guy who Hates Being Alone and just wants to have friends, Robotnik is a Jerkass and Misanthrope Supreme who embraces his loneliness and makes a point of having no friends at all.
- Oh, Crap!: His reaction in the climax when he sees Robotnik's hover jet enter Bullet Time along with him and keep pace with him.
- Paper-Thin Disguise: His "disguise" when at the western bar is a red shirt and a hat. Somehow it works, and no one but Tom finds anything strange about a little blue skinned humanoid around. A waitress believes Sonic to be Tom's child, and the sheriff comes up with a lie on the spot to justify his appearance.
- Parental Abandonment: As in most incarnations barring maybe Sonic Underground and the Pre-Genesis Wave Archie Comics' Sonic the Hedgehog to a certain extent, Sonic's parents are non-existent. His only parental figure is another older animal, this time an owl.
- Pop-Cultured Badass: Naturally considering how he's been raised on Earth pop culture since he was a small child and basically one of his few means of interacting with the world.
- Power Incontinence: Whenever he's sufficiently upset or distressed, his powers overload in the form of light-blue electricity. The first time this happens, the plot-inducing power surge occurs. He learns to control it in time to put an end to Robotnik.
- Randomly Gifted: We're given no explanation as to why he was born with his powers or who his biological parents were.
- Rapid-Fire Fisticuffs: Attempts this in a bar fight, but has no effect. He resorts to Bullet Time instead.
- Required Secondary Powers: As the bar fight displays, while Sonic may be unbelievably fast, that doesn't necessarily make him strong. It isn't until the final battle with Robotnik where he fully grasps using his momentum to fight and actually completes the Spin Attack.
- Sad Clown: He still has his signature cocky attitude and makes plenty of quips, but it's all to cope with the loneliness he suffers from, having escaped his home dimension and not allowing himself to befriend anyone lest he put everyone in danger. His only alternative to observing the people of Earth make friends and live their lives is to escape to a barren mushroom planet with absolutely no intelligent life aside from himself. It's not until he attempts to play a climactic inning of baseball with himself that his loneliness finally overwhelms him, causing him to unleash his stress by running fast enough to cause a nationwide blackout and kick off the plot.
- Sent Into Hiding: Sonic was hidden by Longclaw from the echidnas wanting his power. When he was caught by them and forced to live on Earth, he had to remain concealed there from sight of humans in case they wanted his power. And they did, forcing him to reveal himself to the "Donut Lord".
- Shock and Awe: Sonic's able to conduct electricity, normally shown when he's using his Super Speed and signifed by Glowing Eyes. Both trailers show him accidentally producing enough while running to cause an EMP blackout across the entire Pacific Northwest. Even his quills are capable of generating unlimited energy and Robotnik used one to power his flying machine.
- Skewed Priorities: Sonic throws a What the Hell, Hero? speech at Tom over leaving Green Hills while they get chased by a killer robot. Tom calls him out on it.
- Sleep Cute: Sonic vows to stay up all night while he and Tom are laid over at a motel but as soon as Tom goes to turn off the light so he can sleep, Sonic has already drifted off to sleep like a child who had an exciting day at the theme park.
- Spin Attack: Of course, Sonic's a hedgehog. He knows how to curl into a ball, and he knows how to spin at high speeds, but he doesn't know how to weaponize this skill. At first, anyways. He figures it out during the movie's climax, weaponizing his speed against Robotnik.
- Stalker Without a Crush: He spent most of his time in Green Hills spying on the citizens, considering himself part of the town and particularly enjoying movie nights with an (unaware) Tom and Maddie Wachowski.
- Stepford Smiler: He acts happy with his life without interaction with Green Hills' citizens but it's only to cover up how alone and distant he feels, which tends to come out when he reflects on his situation (a particularly bad moment kicking off the events of the movie).
- Strong as They Need to Be: During the first trailer, Sonic's speed is a bit inconsistent. One minute, Tom is able to tag him in the leg with a tranquilizer dart before he has a chance to react. The next, he's shown going into Bullet Time, moving so fast that hundreds of missiles and robots Robotnik sicced on him appear completely frozen. This is averted in the movie, where it's clear that Tom tags him because he's too distracted by the two of them screaming at each other to react.
- Super Drowning Skills: When Tom tells Sonic to "head west," Sonic speeds off, but then returns soaking wet with seaweed, a starfish, and a saltwater fish on his head. Sonic claims he got them from "crashing into the Pacific". Thus, much like his game counterpart, Sonic can't swim.
- Super Speed: Wouldn't be Sonic without it. He's called "the fastest thing alive" for a reason, after all.
- The first trailer sees Sonic zoom past Tom's police cruiser. The car's radar gun clocks Sonic's speed at 760 miles per hour, which is just under Mach 1.
- The second trailer shows him moving so quickly around a baseball diamond that he causes an EMP that causes a gigantic blackout in the United States' Pacific Northwest. He also speed reads a stack of comics on The Flash, moves fast enough to play table tennis and baseball with himself, and runs fast enough to be in multiple locations at once.
- Sonic can use his power to enter Bullet Time, with everything around him appearing to stand still. Robotnik uses this against Sonic with one of his quills, able to enter the same state to keep up the chase.
- Super-Speed Reading: Can read his large stack of The Flash comics in seconds. He also learns how to drive a car by reading the manual while being chased by one of Robotnik's robots.
- Talking to Themself: Sonic has adopted this habit since he's going mad from isolation, has no one to talk to and has to play his own therapist and his own baseball team.
- Thinking Up Portals: The Power Rings in this film allow instant teleportation from one place to another, be it another land, country, or world altogether. All he has to do is think of a destination, and throw the ring.
- Time Stands Still: How his Super Speed is portrayed when showed from his own perspective.
- Tired of Running: He spends most of the film on the run from Robotnik, planning to use his rings to flee Earth. During the climax, he decides this, going all out and eventually banishing Robotnik himself from Earth.Sonic: This is my power, and I'm not using it to run away anymore. I'm using it to protect. My. Friends!
- Trademark Favorite Food: Chili cheese dogs, as has become typical for the character. He tasted his first ones at the bar, since because the hot wings he originally ordered never came on time, he tried (and accordingly ate an entire basket of) chili dogs instead during his slow-motion run through the Bar Brawl.
- Unskilled, but Strong: He generally uses his speed to get through trouble, and since he's too fast no one can keep up with him or catch him. When Robotnik is able to match him in speed with his own skill, he briefly freaks out as that's the first time it's happened. And from then on, he has to rely on strategy, and eventually assistance from Tom, to defeat him.
- Vocal Dissonance: In the first trailer, he had a very child-like design and a very adult-sounding voice. His design and vocal work following the second trailer's redesign look more like a teenager.
- Weak, but Skilled: As shown in the Bar Brawl, Sonic doesn't have much strength behind him in a straight-up fist fight where he can't use his speed power; when he does Rapid-Fire Fisticuffs on a large biker, it does nothing at all. Instead, he wins by dropping a mounted bear's head on top of the thug and tripping him.
- What the Hell, Hero?:
- He wasn't exactly pleased with Tom for tranquilizing him and making him lose his rings.Sonic: I shouldn't even be on this planet right now, but I am. Why? Because you shot me!
Tom: I know...
Sonic: YOU SHOT ME!
- He also isn't happy when Tom tells him of his plans to leave Green Hills for San Fransisco, so much so that his powers start to flare up.
- He wasn't exactly pleased with Tom for tranquilizing him and making him lose his rings.
- White Gloves: While he doesn't have them in the first trailer, he does wear them in the second trailer, the TV spots and the actual film (as pictured above).
- You Can't Go Home Again: Sonic was forced to flee his homeworld as a child due to being hunted by an echidna tribe who wanted him to harness his power. Longclaw, giving him her power rings and opening one to Earth, stressed that because of his power, he would always be hunted by villainous factions so long as he remained on his planet, thus why he hasn't gone back in 10 years. However, due to Tails' arrival, it's likely things have changed there since Sonic has been gone.
Voiced by: Donna Jay Fulks, Verónica López Treviño (Lain-American Spanish dub)
A wise owl acting as Sonic's caretaker when he was a child. After he gets followed by a group of tribal Echidnas, she uses and gives him Power Rings to escape to another world.
- Annoying Arrows: She's shot with an echidna's arrow mid-flight, but aside from being knocked out of the air, she doesn't seem any worse for the wear.
- Canon Foreigner: Created solely for the movie, although based on Sophocles from Stay Sonic.
- Canon Immigrant: As a tie-in with the movie, she makes a playable (presumably non-canon) appearance in the Sonic Forces mobile game, complete with a more stylized redesign to match the look of the games proper.
- Composite Character: Being an owl who is initially the only character on Sonic's world to be aware of Sonic's existence, makes her a rough analogue of Sophocles the owl from Stay Sonic who was the first to discover Sonic. But her acting as Sonics mentor and Parental Substitute and being the one to give him the Power Rings is taken from Uncle Chuck from Sonic Sat Am.
- Half-Dressed Cartoon Animal: Despite being wise, she is half-naked and the only thing she wears is a gold chestplate.
- Heroic Sacrifice: While she could've went with Sonic to Earth, she decides to stay behind and delay the tribe long enough until the Warp Ring closed despite knowing the Echidna Tribe would likely kill her. We never find out her fate.
- I'm Dying, Please Take My MacGuffin: She gives Sonic the bag of rings just before she sends him through the portal to Earth.
- Mama Bear: She is perfectly willing to act as a shield against the Echidnas to allow Sonic to escape.
- Non-Standard Character Design: Instead of a typical "Mobian" character in Sonic's world, she happens to be a normal great horned owl who is giant and can talk. Even her game redesign in the Sonic Forces mobile game only slightly tweaks her design.
- The Obi-Wan: Sonic explicitly describes her as "basically Obi-Wan Kenobi, if Obi-Wan Kenobi had a beak and ate mice."
- The Owl-Knowing One: Wise, motherly and was responsible for giving Sonic the Power Rings.
- Parental Substitute: Acts as a mother figure for Sonic back on his home planet.
- Retired Badass: According to the novelization she was once part of an order of warriors dedicated to maintaining the planet's balance, but by the time Sonic met her she was a caring mother figure who didn't battle anymore.
- Small Role, Big Impact: She gives Sonic the bag of rings in the beginning, which play a major role throughout the movie.
- They Would Cut You Up: She always stressed that Sonic had to keep his powers secret for this reason. Between the echidna tribe and Robotnik, she was right. Though it's after Sonic has spent time with Tom that the former started wondering if Longclaw was wrong and if it is possible for him to live peacefully with other people even with his powers.
- Uncertain Doom: Because the portal ring closes before it's shown what happened, it's not clear whether the Echidna Tribe killed her or not.
- We Hardly Knew Ye: The last a young Sonic sees of her is standing between the opened portal and the group of Echidnas chasing him before the portal closes, this being just a few minutes after her introduction.
- You Shall Not Pass!: Stays behind to delay the echidna tribe and allow Sonic to get through the Warp Ring.
A tribe of echidnas after Sonic's powers.
- Age Lift: In the games, Pachacamac lived 4000 years before Sonic was born. Here, he's alive when Sonic was a toddler.
- Freeze-Frame Bonus: First time viewers probably aren't gonna notice that the echidna who shoots down Longclaw is Pachacamac, the tyrannical tribe leader from Sonic Adventurenote . The detail was so easy to miss that Tyson Hesse had to publicly reveal the cameo on his Twitter.
- Greater-Scope Villain: They were the ones chasing Sonic on his home planet to harness his power. And it was because of them seemingly killing Sonic's mentor Longclaw that Sonic had to go to Earth.
- Malevolent Masked Men: They wear tribal masks, and were pursuing Sonic to garner his powers.
- Predator Pastiche: The Echidnas, depicted with dreadlocks, masks and various tribal weaponry, hunting a young Sonic in the jungle.
- Small Role, Big Impact: Their total screentime is very short, but they're the entire reason Sonic is on Earth in the first place.
- Spared by the Adaptation: In most Sonic media, Knuckles is the Last of His Kind. Here however, the echidnas are still around when Sonic is young.
- Starter Villain: They're the reason Sonic has to abandon his home world and flee to Earth.
- The Un-Reveal: We never find out what they wanted Sonic's power for that they had to hunt him down so severely.
Voiced by: Colleen O'Shaughnessey (uncredited in theatrical releasenote ), Cecilia Gómez (Latin-American Spanish)
A flying two-tailed fox who is also from Sonic's homeworld and comes to Earth looking for him.
- Adaptation Dye-Job: Downplayed. Tails looks very much like he does in the games, but his fur is a more vibrant shade of orange (much like he had in the older games) compared to the more yellow fur he has in 3D Sonic games.
- Ambiguous Situation: Because he doesn't interact with anyone else, it's unclear why Tails is searching for Sonic, or if they even know each other. Tails clearly knows of Sonic, but nothing is established about how Tails knows him.
- Cartoony Tail: Much like his game counterpart, he has two tails that he can spin like a helicopter's rotor blades to fly through the air.
- Continuity Cameo: He appears for about 15 seconds at the very end, having spent much of the movie off-screen back in Sonic's world looking for him.
- Establishing Character Moment: The first thing Tails does upon arriving on Earth and discovering Sonic's whereabouts is to jump off a cliff... and perform his signature Propeller Flying ability to hover back up before speeding off to find him.
- Flight: Just like his game counterpart, Tails can rapidly spin his twin tails to fly.
- Leaning on the Fourth Wall: He says that he hopes he's not too late... having arrived during The Stinger, after the events of the movie.
- Mythology Gag: The yellow scanning device he uses to find Sonic on Earth closely resembles the Miles Electric.
- Sequel Hook: He shows up after the movie's conflict is over, determined to find Sonic on Earth. It hints at another movie where he is actively involved.
- Super Speed: Much like Sonic, Tails can move incredibly fast. He flies from the top of a cliff overlooking Green Hills into the town proper in just a few seconds, leaving an orange trail behind him.
- Vocal Evolution: Colleen's voice for Tails here is deeper and more boyish-sounding compared to her past portrayals of the character.
- Walking Spoiler: The fact that Tails shows up at all is a spoiler in and of itself; he had never been mentioned before his brief appearance in The Stinger.
- White Gloves: Like Sonic, he wears these.
Sheriff Thomas Michael Wachowski
Played by: James Marsden, Yuichi Nakamura (Japanese dub), Luis Leonardo Suárez (Latin-American Spanish dub)
Tom: He's my friend.
Green Hills' sheriff and Sonic's first human ally. Tom wants to break out of small town life and prove he has what it takes to be a cop in the big city. However things go very weird when Sonic enters his life, putting him in a compromising situation with both the US government and his future plans.
- Affectionate Nickname: Sonic refers to him throughout the movie as 'the Donut Lord,' because Sonic observed that he "talks to donuts, then eats them if they step out of line."
- Appropriated Appellation: Sonic's "Donut Lord" nickname for him. Tom initially doesn't like it, but adopts it for himself much later.Tom: (to Robotnik) I'm the Donut Lord, you son of a b-!
- Canon Foreigner: He doesn't exist in the video games.
- Challenge Seeker: The reason he wants to move out of Green Hills and into San Francisco is because the small town life bores him. There's no challenge for Tom in helping people recover bagels stolen by ducks and sitting at a speed trap.
- Deadpan Snarker: He has his moments, especially when talking to Robotnik.
- Defrosting Ice King: At the start of the movie, he's not pleased that he has to accompany Sonic on his quest to retrieve his rings, but he softens up considerably thanks to Character Development.
- Donut Mess with a Cop: He's a local town cop who loves eating donuts, even talking to them to practice his promotion acceptance speech. Sonic has taken notice during his time on Earth and gave him the nickname "Donut Lord". Tom eventually uses it as an Appropriated Appellation while fist-fighting Doctor Robotnik in the climax.
- Easily Forgiven: He is never punished for assaulting a government agent, or at least a government contractor. Considering the person he punched out was Dr. Robotnik, nobody seemed to care that much.
- Fair Cop: A town sheriff who wants to be a cop in a big city, and played by James Marsden.
- Fatal Flaw: Impulsiveness. Tom has a "shoot first, ask questions later" mentality, and he gets himself into deeper and deeper trouble because of his tendency to act before he thinks.
- Shooting Sonic with a tranquilizer dart made Sonic drop his Power Rings, necessitating the road trip from Green Hills, Montana to San Francisco, California.
- Punching Robotnik in the face made it personal with him, getting Tom on the bad side of the mad scientists and the US government.
- Averted at the end after some Character Development on Tom's part. Though he gets into the SFPD at last, he chooses to reject their offer and go back to Green Hills with Maddie, letting Sonic live in their attic.
- Fire-Forged Friends: Becomes this over time with Sonic. After the myriad of adventures they have trying to get to San Francisco, Tom grows genuinely attached to Sonic. He even lets Sonic live in his attic once Robotnik is gone.
- Flaw Exploitation: After learning that Robotnik's Berserk Button is being punched in the face, Tom exploits it by repeatedly punching Robotnik, making Robotnik lose focus on Sonic at a critical moment.
- Goal in Life: To become a police officer in San Francisco. Before the movie starts, this hadn't been going well, seeing as how Maddie baked two cakes and presented the one as if Tom had been rejected. Tom does get accepted to the SFPD early on in the film, but decides to remain in Green Hills to help the people he cares about most.
- Happily Married: To Maddie. When she was in veterinary school, he worked three jobs to pay the bills and her tuition. And even when he lands his dream job, he wants to make sure that she is okay with uprooting and moving.
- Heroes Love Dogs: He considers his golden retriever, Ozzy, as his "best animal friend," much to Sonic's dismay.
- A Hero to His Hometown: Whenever there's trouble in Green Hills, Tom is the first person everyone calls for. While Tom sometimes thinks he's wasting himself in a little town where he does very real police work, he's still a caring, competent officer, and all the residents respect and appreciate him. During the climax, the entire town rises to Tom's defense when Robotnik threatens him.
- Hero with Bad Publicity: He becomes a fugitive from the Government and the news calling him a suspected domestic terrorist; after punching Robotnik and helping Sonic escape. Even Sonic didn't like at him first, which is justified since Tom made him lose his rings AND refused to help Sonic retrieve them!
- Hypocritical Humor: Considering that he eats a dozen donuts a day, it's rich that he would complain about the unhealthy meal that he bought for Sonic.
- I Choose to Stay: He makes plans to relocate to San Francisco after the SFPD hires him. Ultimately, however, he and his wife decide to remain in Green Hills following Robotnik's defeat and allow Sonic to reside in their attic.
- I Just Want to Be Special: Part of the reason why he wants to move to the big city is that he doesn't feel he's doing anything truly life-changing in a small town like Green Hills. It's also likely what gets him to help Sonic despite the trouble it would cause him.
- Jerk with a Heart of Gold: Initially wants nothing to do with Sonic's quest, but thanks to Character Development, he warms up to Sonic and adopts him in the end.
- Lame Comeback: During his first encounter with Robotnik, the mad scientist brags about his intelligence by saying he could solve formulas as a toddler while Tom was "spitting up formula". Tom attempts to retaliate by saying he was breastfed.Robotnik: Nice, way to rub that in my orphan face.
- Mr. Fanservice: It's a given, being played by a former Versace Model and all, even Sonic lampshades it, mention how tightly all of Tom's clothes fit him.
- Nice Job Breaking It, Hero!: He accidentally sets the whole plot in motion. When Tom first meets Sonic, he shoots him with Maddie's tranquilizer darts. A dazed Sonic accidentally drops his Power Ring bag, mumbles "San Francisco" (from Tom's T-shirt), a Ring portal opens, and the bag of Rings fall on top of the Transamerica Pyramid Building. The portal then closes before Sonic is able to go through, necessitating a road trip to go get the bag.
- No-Holds-Barred Beatdown: Tom gains a dedicated disdain from Robotnik early on, second only to Sonic when it turns out getting socked in the face is a direct trigger to the malicious egomaniac's unresolved issues from childhood. So, to try and get Robotnik's focus off of Sonic when he has him cornered, Tom hammers on this Berserk Button liberally by getting onboard his craft via ring to belt him senseless.
- Papa Wolf: Becomes fiercely protective of Sonic over the course of the movie, even going so far as to adopt him.
- Parental Substitute: After he agreed to help Sonic, he started having moments of being one to the Blue Blur. And that was even before he and Maddie decided to adopt Sonic.
- Shut Up, Hannibal!: During the climax, he gives one to Robotnik in response to his dismissal of Sonic as a "silly little alien" who doesn't belong on Earth, telling him point-blank that Sonic may be an alien, but he knows more about being human than Robotnik ever will.
- Small Town Boredom: This is his motivation for wanting to leave Green Hills for San Francisco. He wants to join the SFPD because he wants to be challenged in his abilities as a police officer and have someone rely on him. There's no challenge for Tom in helping people recover bagels stolen by ducks and sitting at a speed trap. Sonic calls him out for wanting to stop defending Green Hills just for a higher ranking position in a bigger urban city. At the end of the film, he chooses to stay in Green Hills after all and let Sonic live with him and Maddie.
- Trademark Favorite Food: Donuts. He is said to eat donuts everyday and revolves his life around donuts by not just eating them but treating them like toys or imaginary friends to talk to.
Played by: Tika Sumpter, Marina Inoue (Japanese dub), Carla Castañeda (Latin-American Spanish dub)
Tom's wife and an animal veterinarian. She assists Sonic in his travels.
- Affectionate Nickname: Like with Tom, Sonic refers to her throughout the movie as "Pretzel Lady", because he thinks that she was born with no bones during one of her yoga sessions.
- Canon Foreigner: Like Tom, she isn't from the games.
- Closest Thing We Got: After Sonic is injured from one of Robotnik's robots exploding like a sticky grenade, Tom takes Sonic to meet Maddie. She might not know a lot about alien biology, but she's really his only option.
- Crazy-Prepared: When Tom's letter from the SFPD arrives, she actually got two celebration cakes ready in case he was accepted or rejected by the letter.
- Dissonant Serenity: Invoked. She remains oddly calm when Tom shows up to San Francisco with Sonic, an alien hedgehog, and even talks about how calm she is being with Tom, not "freaking out," before screaming at him about the ridiculousness of what has been going on, especially Sonic.
- Happily Married: To Tom. After he lands his dream job, she is more than willing to uproot and start a new life with him. And even after he's been all over the news as a wanted man, she trusts him enough to treat the strange, blue alien he brought along with him. No matter how much her sister wants her to divorce Tom, Maddie won't do it and they stay together.
- Kindly Vet: A Nice Girl who works as a veterinarian.
- Ms. Fanservice: One of her first scenes is her in gym wear doing yoga exercises. It's played for laughs, though, since Sonic thinks she doesn't have bones (and nicknames her "Pretzel Lady" for it) and has trouble himself copying her moves.
- Nice Girl: A very nice and kind girl, and very loyal to her husband.
- Oh, Crap!: Has this reaction upon realizing that after Sonic teleported her and Tom back to Green Hills, she left her sister tied to a chair HOURS earlier.
Dr. Ivo "Eggman" Robotnik
Played by: Jim Carrey, Kōichi Yamadera (Japanese dub), Mario Castañeda (Latin-American Spanish dub)
Completely full of himself, with the IQ and evil ambitions to match, Dr. Robotnik is a scientist hired by the US government in their attempts to detain Sonic. He invents and controls various machines, most of which are piloted remotely.
- 0% Approval Rating: Robotnik is despised by almost everyone except for Agent Stone. And given he's a rude, obnoxious Mad Scientist, it's not hard to see why. The government only hires him because he's just that good in spite of how much of a jerk he is, and only brings him in to capture Sonic once they realize they have no other choice. When Robotnik is banished to the Mushroom Planet, they're happy he's gone and immediately remove any trace of his existence.
- Ace Pilot: He pilots a vehicle that fires laser bullets and rockets which he uses to try and kill Sonic with.
- Adaptational Angst Upgrade: He reveals to one cop that he grew up in an orphanage where he was bullied as a child. In the games, his past is left vague but is implied he had parents, as he at least had a grandfather.
- Adaptational Attractiveness: Robotnik looks much more dashing when played by Jim Carrey. He's in better shape, has a full head of hair and his mustache is well-groomed. Subverted in The Stinger which shows that after ending up stuck on Mushroom World, he has shaved his head and grown out his mustache so it's now bushy like his game counterpart, but has retained the more fit body albeit with a bit more weight gained.
- Adaptational Badass: Played With. Robotnik's physical capabilities vary across the canons. Some are strong enough to punch through metal, others are much less capable in a physical fight and rely on machines alone. Jim Carrey's incarnation is shown to be capable of holding his own, acquitting himself against a biker that was giving even Sonic trouble. At the same time, he is by no means an unstoppable physical force either, as shown when Tom manages to punch him out in the beginning. This incarnation thus seems to fall somewhere in the middle as a physical fighter.
- Adaptational Context Change: In the games, he is given the nickname "Dr. Eggman" based on his cartoony oval shaped body. In the movie, Sonic gives him the nickname based on his flying drones which are ovoid and white.
- Adaptational Jerkass: While no version of Robotnik is a Nice Guy, in the games he's a legitimately Affably Evil villain with some positive qualities who is prone to Enemy Mine situations with the protagonists. Here, he's portrayed as a massive Jerkass who is pretty much incapable of being in the vicinity of another living being for very long without being condescending and rude to them.
- Adaptation Dye-Job:
- Played With in regards to his hair color. In the games, his hair has varied in color between orange, auburn red, and dark brown. Here, Robotnik starts out with a full head of dark brown hair and mustache, then in the stinger he's shaving his hair off to be bald and has gained a more reddish mustache.
- In the games, the few times Robotnik has been shown with his goggles off he's had blue eyes. Here Robotnik has Jim Carrey's brown eyes.
- Affectionate Nickname: Like with the Wachowskis, Sonic refers to him as 'Eggman,' because of his egg-shaped drones. However, it's anything but affectionate.
- And There Was Much Rejoicing: After Robotnik's disappearance into Mushroom Planet, the United States government pretends he never existed, and they're all too happy to forget about him.
- Ax-Crazy: Robotnik is already insane to begin with, but his growing frustration with Tom and Sonic worsens his insanity. By the end of the film, he's arguably long gone off the cliff.
- Badass Bookworm:
- While briefly recounting his childhood to Tom after their initial encounter, he mentions that he was once punched in the face by a school bully, and put said bully in hospital in retaliation, leaving them "eating through a straw" for at least a year after.
- Later, when he encounters the same bar brawler who shrugged off being hit in the head by a bottle (and Sonic's Rapid-Fire Fisticuffs), he ends up throwing him through a window.
- Badass Longcoat: Starts out wearing this, but later on he starts wearing his standard red outfit.
- Badass Mustache: Has two variations: One is small, dark brown, and neatly styled, while the other overtakes half his face, is reddish and disheveled, and is much more closely based on his mustache in the video games.
- Badass Normal: Robotnik has no supernatural powers of any kind, like Sonic's super speed. He is a master of technology who excels at building deadly robots who almost killed Sonic for real. Even when stranded on the alien Mushroom Planet, he vows it won't stop him from returning to Earth.
- Bad Boss: While he is the only person Robotnik shows any kindness too, he treats his underling, Agent Stone, not unlike how the SatAM version of Robotnik treated Snively.
- Bald of Evil: At some point after he is banished to the Mushroom Planet, he shaves his head with a sharp piece of debris from his ruined flying machine (complemented with a wilder 'stache).
- Berserk Button: Being punched in the face. It reminds him of unpleasant childhood memories. When Tom does it, he makes it personal with Robotnik, making the doctor want to ruin Tom's life as much as capture Sonic.
- Beware the Silly Ones: He is silly, obnoxious and quite childish, but also a corrupt mad scientist with sinister plans, genuinely dangerous machines, and no empathy to care who ends up hurt in the crossfire of either. He even manages to nearly kill Sonic in their final fight.
- Big Bad: The main antagonist of the movie. He's a government agent employed to track down Sonic and take the secrets of his powers, which he does with extreme prejudice, although to exploit that power for himself. Even Robotnik's nominal allies in the United States government would rather have nothing to do with him because of his reputation as a Mad Scientist, but he's the only one who can conceivably catch Sonic.
- Blinded by Rage: After Tom learns of Robotnik's Berserk Button, Tom invokes it to make Robotnik angry enough to slip up. Tom warps up to Robotnik's hovership with a Ring and starts punching him repeatedly in the head, angering Robotnik enough to lose focus on Sonic at a critical moment and set him up directly for his defeat.
- Boomerang Bigot: Robotnik looks down on humans as inefficient even though he is human himself. Given how deluded he is, it's possible he thinks he's the sole exception to the rule or above normal humans.
- The Bully: Though he hates bullies due to his childhood trauma of having to deal with one as a child, Robotnik is no better than one. He is rude and unpleasant to everyone he comes across, and uses his authority and resources to threaten and demean others, as well as throwing his weight around them.
- Bunny-Ears Lawyer: He is extremely weird and a huge asshole, but is also one of the most intelligent scientists in the world, hence why the US military (reluctantly) has hired him for some dirty jobs and brings him on to investigate the Pacific Northwest blackout.
- Card-Carrying Villain: He calls his drones "Badniks", acknowledges his truck as an "Evil Lair", has his lab labeled as "Evil Lab" on his circuit breaker, and dances to "Where Evil Grows" by the Poppy Family while studying Sonic's quill. Can't get any less subtle than that!
- Chewing the Scenery: Robotnik does this in just the first few minutes of his introduction, interrupting one of the generals with a loud, demanding voice. He doesn't slow down from there.
- Cloudcuckoolander: He's quite the wacky character, and clearly even wackier after being banished to the Mushroom Planet. Being played by Jim Carrey certainly helps.
- Companion Cube: In the first stinger, stranded on the Mushroom Planet, has made himself a new "Agent Stone" to keep him company/boss around... by taking a literal stone, carving it into the likeness of the real one, and throwing it around to go on "Rock-connaissance".
- Composite Character:
- Played With. Robotnik being a goverment scientist is shared with his grandfather from the games, Gerald Robotnik. His disdain for organic life and instead trusting on machines, while is implied with Eggman in the games, is more in line with Lyric from Sonic Boom: Rise of Lyric.
- His final design, based on a flight red suit is in line with Eggman's design in Sonic Boom, with a certain dash of his infamous 2006 design. Both of these designs are known for not having the good ol' doctor as a comical Fat Bastard, but instead looking fit or average in shape, perfect for a live action movie.
- His personality is very silly and over the top like is most games and cartoons. But when he is being threatening to Agent Stone he comes off more like Dr. Robotnik from Sonic Satam.
- Control Freak: Why he prefers machines to other humans: they can only do exactly what he wants them to do, and do so without hesitation or doubt.
- Cool Shades: Standard for Robotnik, he wears sunglasses in a lot of his scenes.
- Crazy-Prepared: He had the foresight to design an armed robotic vehicle to deploy a smaller one from its underside in the event it gets tipped on its side, and the smaller vehicle can in turn continue functioning so long as it has even one wheel left. And even if it loses that, its eye can take flight and has some manner of cutting laser. If it stops working in that form, it becomes a Sticky Bomb. If one looks closer at the designs for the larger segments of the creations, you can see even more eventualities being planned for, such as having literal eyes in the back of its 'head'.
- Cut Lex Luthor a Check: Zigzagged throughout the movie. His brilliant inventions could earn him a lot of honest money, but he does work for the American government, meaning he has an "honest" job- even though it's mentioned he helped in coups against nations in the Middle East. And then, after obtaining one of Sonic's quills, he uses it for his own purposes of building more robots, instead of researching it as a new energy source.
- Dark and Troubled Past: Played for Laughs example. He was orphaned as a child, and at school, he was punched in the face by The Bully. Instead of reporting to the principal like normal, he took his revenge and somehow left the bully in question only able to eat through a straw for at least a year. Also, that was how he got the Berserk Button from being punched.
- Dastardly Whiplash: He's got a prominent chin, curled mustache, black coat and flamboyantly villainous personality. His mustache grows even bigger when stranded on the Mushroom Planet. Ironically, Jeff Fowler stated that he wanted to defy certain aspects of this trope, calling the game version of Robotnik "moustache-twirly" and saying he wanted this interpretation to be more "grounded."
- Deadpan Snarker: As hammy and crazed as he is, Robotnik also has a penchant for snarky one-liners:Robotnik: I'm initiating a sweep sequence! (Inputs commands on his glove to activate his flying drones) Ten miles in every direction should suffice. Is he [Bennington] still looking at me funny?
Stone: Yes, he is.
Robotnik: (nonchalantly) Tell him to stop, or I'll pull up his search history.
- Determinator: Even after being banished to the Mushroom Planet, spending 87 days there alone, and completely losing his mind, Robotnik refuses to give up and is determined to find a way back to Earth.
- Disproportionate Retribution: He threatens to pull up Major Bennington's search history for continuously looking at him funny. He also develops a vendetta against Tom all because the sheriff slugged him across the face, and vows to ruin his life out of revenge as well as capture Sonic.
- The Dreaded: When one of the Generals at the Pentagon suggests bringing Robotnik in to investigate the blackout in the Pacific northwest, the others react with dread and ask if there was any other recourse.
- Drink-Based Characterization: He drinks lattes with steamed Austrian goat milk, which are prepared by his lackey Agent Stone, to showcase his ludicrous standards and overbearingness.
- Establishing Character Moment: When Robotnik meets with the military, he wastes no time in showing everyone how insufferably vain and abrasive he is.Robotnik: I'm sorry, Major. What was your name?
Major Bennington: Benningt-
Robotnik: -NOBODY CARES!
- Even Evil Has Standards: No, not him personally, but he does get a few Played for Laughs examples.
- While chasing after Sonic in his prototype flyer, he calls out Sonic for making an illegal left turn, and chastises him for running up one of the pyramids of Giza, pointing that they are one of the seven wonders of the world (even though he blew up the Sphinx's head beforehand).
- When Sonic shoves Tom and Maddie off a building, Robotnik is horrified and even stating, "I was not expecting that.". But he was expecting not to expect something so it doesn't count.
- Evil Cannot Comprehend Good: Robotnik is genuinely confused as to why Tom is going out of his way to help Sonic despite how much chaos he's brought into his life. Tom's reply is simple, but effective:Tom: He was my friend.
- Evil Counterpart: To Sonic. Sonic is an alien hedgehog who ultimately just wants companionship and makes it a point to look out for those who care about him. Robotnik, meanwhile, is ultimately a power-hungry sociopath who doesn't care about friendship and is a total dick to just about everyone except Agent Stone sometimes, despite being human. Not to mention that both of them have been orphans at one point in their lives.
- Evil Genius: He creates rather impressive gadgets and machines, but he's also in this solely for his own motivations. He's also a complete jerkass.
- Evil Is Hammy: Jim Carrey as Dr. Robotnik. He's clearly having the time of his life bringing Robotnik to the big screen, combining his penchant for loud and manic characters with the already bombastic nature of the source character. Whether it's him dancing while preparing his vehicles, to screaming about his love of lattes with steamed Austrian goat milk, his portrayal is definitely one to be remembered. Then there's the moment Robotnik has a Freak Out, complete with exaggerated movements, after Sonic destroys his robots on the highway.
- Evil Is Petty: He wants to ruin Tom's life in addition to capturing Sonic because Tom punched him. It reminds Robotnik too much of a childhood bully.
- Evil Laugh: Lets off a truly hamtastic one over his bizarre "rock-connaissance" joke, made more menacing by his Vocal Evolution.
- Evil Orphan: Robotnik off-handedly mentions growing up as an orphan to Tom at least twice: once when they first meet, and the next while he's threatening him over the phone when he and Sonic are at the truck stop.
- Evil Wears Black: Compared to his game counterpart's red and white attire, this Robotnik is introduced wearing almost completely black. That is until the next half of the film, where he's changed to red.
- The Exile: At the end of the film, Sonic and Tom foil Robotnik's plans by banishing him to the Mushroom Planet. However, he insists that he'll be "home by Christmas" with one of Sonic's quills.
- Fantastic Racism: Robotnik has a massive disdain for any organic life compared to technology, as it does what it's told and is much more efficient. Played With in that he himself is a human with these beliefs as opposed to a robot or an AI.
- Faux Affably Evil: He's able to act civil and polite when he wants to, but even then, it seems he can't even be in the same vicinity of another human being for long without being rude and insulting in some manner. Best shown when he tracks Sonic to Tom's house; he introduces himself to Tom cordially, but soon devolves into bragging about his intelligence while mocking Tom's own before casually threatening him with a drone for Sonic's location.
- Fingerless Gloves: He later wears a pair of these while also wearing his red outfit and goggles.
- Freudian Excuse Denial: He grew up orphaned, with no friends, bullied at school and a burdensome power, much like Sonic. Unlike Sonic, he decided to embrace the loneliness by retreating into his ego, deciding he was superior to the rest of humanity and that friends would only drag him down, and used his power for his own irresponsible self-benefit rather than to help anyone. In the present day, he gladly boasts about his troubled childhood as having helped him become the "superior" person that he is now.
- Go Mad from the Isolation: Not that he was all that sane to begin with. Having been stranded in the Mushroom Planet for 87 days and shaving his head completely bald hasn't given his sanity any help. He even adopts a Companion Cube rock and calls it Agent Stone after his former lackey. In spite of this, he makes a Badass Boast that this isn't going to hold him back.
- Glowing Mechanical Eyes: Not him, but his inventions tend to have one akin to HAL 9000.
- Godzilla Threshold: The entire reason the US government hired him to capture Sonic in the first place. It's made clear that they can't stand him since he's a rude, obnoxious Insufferable Genius. But they feel that they have no choice but to hire him.
- Gratuitous Japanese: When he examines a strand of Sonic's quills up-close, he utters "omoshiroi" ("interesting").
- Hate Sink: Despite being Laughably Evil, Robotnik has no redeeming qualities (except for one Pet the Dog moment towards Agent Stone) that would make the audience feel anything but disdain for him. The government establishes early on that working with him is a relationship of reluctant necessity, and he treats the sycophantic agent who accompanies him like complete trash, despite doing everything he is told. This while Robotnik espouses the advantages of AIs over organic beings because of their undying obedience. He is extremely rude to everyone he comes across for no reason, and will wantonly kill anyone who stands in the way of what he wants, which is just a poor blue hedgehog who doesn't want to be chased. Robotnik is so hated so much that no one bats an eye when he's banished to the Mushroom Planet. Not even the U.S. Government, who is all too happy to render him an Unperson the moment he's gone.
- Humans Are the Real Monsters: In stark contrast to Sonic, an alien hedgehog who is ultimately revealed to be very friendly, Robotnik is cruel, sociopathic, rude, abrasive, and power-hungry. Tom even lampshades it during the climax, remarking that Sonic knows more about being human than Robotnik ever will.
- Hypocrite: Robotnik is this in spades.
- When he was punched in the face by a bully as a child, he retaliated with extreme vengeance. But now that he's an adult, he acts like a bully himself, treating everyone else he interacts with contempt and disdain, and hunting down an innocent blue hedgehog just to steal his powers for his own self-benefit.
- He constantly harps on how machines are better than people because machines are efficient and obey him without fail, yet he gets mad at Agent Stone for prioritizing his safety over taking the initiative and chasing after Tom and Sonic when they get away.
- When chasing Sonic, Robotnik gives a shaming remark about Sonic not being allowed to run on the Pyramids after he blew the Sphinx's head off! And then he shoots at Sonic, damaging the pyramid anyway!
- And in spite of all his statements of how worthless every other human being who isn't him is and how he prefers the company of machines, he ends up going mad due to isolation from other humans at the end of the film because without other humans to demean and lord his superior intellect over, his ego has no way of receiving any sort of gratification.
- Related to the previous point, Robotnik berated Agent Stone about how he won't miss him if he's gone at one point, yet he made his likeness with a literal stone to carry around & chat with when he stranded in Mushroom Planet. Also doubles as a Pet the Dog moment as it shows he truly did miss Stone.
- This conversation alone:Major Bennington: Listen pal, I don't know if you realize who...
Dr. Ivo Robotnik: I'm sorry, Major. What was your name?
Major Bennington: Benningt-
Dr. Ivo Robotnik: (interrupts) -NOBODY CARES!
- Improbably High I.Q.: Jim Carrey says that his IQ is 300 points, much like his game counterpart.
- Insufferable Genius: Wouldn't be Robotnik without this trope. The government didn't want to work with him, and the military can't stand him; within minutes of meeting the military, he immediately declares himself superior to Major Bennington and mouths off to him.Robotnik: In a sequentially ranked hierarchy, based on level of critical importance, the disparity between us is too vast to quantify. Agent Stone?
Stone: (matter-of-factly) The doctor thinks you're basic.
- Intelligence = Isolation: It's implied that he was a child genius, which unfortunately made him an outsider amongst his peers and contributed to his ego and lack of empathy with others.
- "It" Is Dehumanizing: During the climax, he outright calls Sonic a "thing" while questioning why Tom would throw his life away to help him.
- It's All About Me: Robotnik couldn't care less about the United States, the government, or anyone except himself. He wants to capture Sonic and study him because he wants to build better robots.Robotnik: That's one small step for man... one giant leap for me.
- It's Personal: After Tom sucker-punches him, Robotnik explains the last time he was punched was by a bully in school. He then got his revenge, and swore that nobody would ever punch him again. Tom just did, so making Tom suffer is now one of Robotnik's goals in addition to catching Sonic.
- Jerkass: He's a rude, obnoxious, and condescending asshole who can hardly finish a sentence without insulting someone. And he's trying to kill Sonic for his own greedy purposes. He's such a jerk that when he's banished to Mushroom Planet, the government pretends he never existed and tries to forget about him.
- Knight of Cerebus: While he's hilarious, the movie does become a lot more serious and action-focused once Robotnik makes his presence known.
- Lack of Empathy: Given that he's a sociopath, this is to be expected. A good example is when Sonic pushes Tom and Maddie off a building (in order to save them), Robotnik is at first surprised, saying he wasn't expecting that, but then shrugs it off, saying "I was expecting not to expect anything, so it doesn't count" while showing an utterly callous lack of concern towards Tom and Maddie falling to their (apparent) deaths. Later, when Sonic is apparently killed, Robotnik taunts the grieving Tom by eagerly going on about how he wants to put the hedgehog's body on ice and dissect him as an alien, while calling him a "thing."
- Large Ham: Being a mad scientist played by notorious ham Jim Carrey, this is a given. When angry or flustered, he's prone to Milking the Giant Cow and shouting at the top of his lungs.
- Last-Name Basis: Everyone refers to him as "Robotnik," including the doctor himself. The only person who doesn't is Sonic, who calls him "Eggman" after the shape of his drones. His first name is never mentioned.
- Laughably Evil: While he's absolutely devoid of redeeming qualities, Robotnik is still one of the funniest characters in the film. Being played by Jim Carrey, this is to be expected.
- Lean and Mean: Unlike his Fat Bastard video game counterpart, this Robotnik is completely slim. Though like his video game counterpart, he's still the same asshole we know and love.
- Love Is a Weakness: In direct opposition to Sonic's outlook of I Just Want to Have Friends, Robotnik vocally makes a point of having no friends. In his stated opinion, the simple fact that people are fallible, while machines can only serve in their designed capacity, is cause enough in itself to forego such attachments altogether.
- Madness Makeover: In The Stinger, he's shaved his head bald and his mustache has grown much longer, reflecting his appearance from the games.
- Mad Scientist: He tends to act quite kooky and hammy, and is an evil scientist hired to hunt down Sonic and aiming to find the source of his powers for his own ends.
- The Men in Black: Works above the system to do whatever he wants if it means getting the job done. In addition, he wears an all-black suit until the final act. Not to mention this line he throws out when Tom tries to use his police authority when he is threatened.Robotnik: How can you threaten someone who never existed?
- Milking the Monster: He uses one of Sonic's quills to power a lot of his inventions. Robotnik's eventual plan for Sonic is to tap into the source of his seemingly-limitless energy to power ever more capable robots.
- Minor Injury Overreaction: A simple punch in the face from Tom is enough to set him off in a major way and decide that It's Personal.
- Misanthrope Supreme: He's a human who hates humanity. Robotnik finds humans to be a letdown, thinks everyone is stupid but him, and makes a point of having no friends. The reason Robotnik loves machines is because of their greater efficiency and how they can only do as they're told.
- Morality Pet: The only nice thing he does in entire movie is compliment the way Stone makes lattes when offered one. Despite claiming he's not going to miss Stone when they depart on the mushroom planet he names a literal rock "Agent Stone" and takes the rock with him indicating he did miss Stone deep down.
- Morally Ambiguous Doctorate: He insists on being called a doctor. And certainly likes less than savory approaches to science, down to saying to a KO'd Sonic that he'll love dissecting his body.
- Narcissist: He is an incredibly insufferable egomaniac. It's to the point that he spends half the time in the presence of others telling them how much better he is than them. The fact that he keeps Agent Stone around as his Yes-Man shows that he needs constant reaffirmation to his ego. His Establishing Character Moment shows him constantly asserting his dominance over the military crew he's working with, belittling the major's credentials without letting him get a word in edgewise, and almost immediately telling him that his men work for Robotnik now.
- Nice Shoes: He appears to be wearing black high-top sneakers that resemble Converse All-Stars.
- No Celebrities Were Harmed: His appearance seems to take cues from Friedrich Nietzsche.◊ Fitting, really, considering that Robotnik thinks himself an intellectual Übermensch.
- Noodle Incident:
- He apparently provided support for the US government during coups against Pakistan and Azerbaijan (or as Waters describes, "Azerbaijanistan"), though what kind of support he gave to them is left unexplained. Judging by a remark from the Navy Chief of Staff regarding the latter ("It's not even a country."), it probably wasn't pleasant.
- As Robotnik mentions to Tom in a phone call, a bully once punched him in the face as a child. Robotnik did something in retaliation that led to the bully eating through a straw for year. It's how Robotnik got his Berserk Button of being punched in the face.
- Not So Similar: Both he and Sonic grew up orphans, with no friends, and a burdensome power (Sonic his Super Speed, Robotnik his Super Intelligence). That's where the similarities end; whereas Robotnik is a Jerkass and Misanthrope Supreme who embraces his loneliness and makes a point of having no friends at all, Sonic is a Nice Guy who Hates Being Alone and just wants to have friends.
- Obviously Evil: He wears black with the later addition of red for the movie, is a total dick to everyone he interacts with, installs ominous glowing eyes in his robots, and wants to capture Sonic for his own nefarious purposes.
- Parental Abandonment: He grew up in an orphanage, he never met his parents and when Tom pointed out he was breastfed by his mother, Robotnik called him a braggart.
- Pet the Dog: The nicest thing he does throughout the course of the film is compliment the way Agent Stone makes lattes when the latter offers him one. He also names a rock "Agent Stone" on the mushroom planet showing that, despite claiming he wouldn't miss him when they departed, he truly did miss Agent Stone.
- Precision F-Strike: Delirious with disbelief and anger, he gives Tom a pointed one after Tom knowingly invokes his anger by relentlessly beating him about the head to save Sonic.Robotnik: Who the hell do you think you are!?
- Psycho for Hire: A misanthropic, malignantly narcissistic super-genius who takes pride in his villainy to the point that he dances to "Where Evil Grows" when he's supposed to be working for the U.S. government.
- Psychopathic Manchild: It wouldn't be Robotnik otherwise. His very hammy personality and delight in being evil show him as a very childish and immature man. He is also very petty, as shown when he makes things personal with Tom after being punched in the face by him.
- Rapid-Fire Interrupting: When addressing Major Bennington, Robotnik constantly cuts him off.
- "The Reason You Suck" Speech: Tends to give these out in quick succession to whomever he feels isn't complying with his demands in the manner to which he is accustomed.
- Red and Black and Evil All Over: Robotnik initially wears a black suit and coat, but once he gets into his prototype hovercraft, he swaps it out for a black and red flight suit and goggles that look more like his traditional outfit.
- Robot Master: Natch. He builds drones, giant robots, and flying machines. He says he does this because machines can only perform in their designated capacity, unlike humans.Robotnik: The time for talking is over! It's time to push buttons!
- Sanity Slippage: As seen in The Stinger, being trapped on Mushroom Planet does a number on his already questionable mental health.
- Screams Like a Little Girl: He has this reaction upon seeing the titular character for the first time, which gives Tom Wachowski enough of a distraction to punch him right in the face.
- Smug Super: Arrogant, condescending, rude, and completely full of himself. However, he's got the brains to back it up by creating extremely dangerous and advanced machines. Even the US government hates his guts, but they let him try to catch Sonic because he's the only one who can.
- The Sociopath: Jim Carrey describes Robotnik's character in an interview as "pure, unadulterated evil", and it shows. Despite his humorous qualities, Robotnik is a ruthless narcissist who sees people only as tools to benefit him, has no problem killing anyone who gets in the way of his plans, doesn't care about any collateral damage, and his intentions are purely selfish.
- Stronger Than They Look: Looks like the type of guy who relies on robots to do the fighting for him, but he is able to throw a man much heavier than him through a window.
- Take Over the World: Upon discovering Sonic and his immense power, he decides to throw the government under the bus and kill Sonic himself. Why? So that he can steal his energy to power his robot army, which he plans to use to achieve global domination.
- Trapped in Another World: At the end of the film, Sonic uses his rings to banish him from Earth and trap him on the Mushroom Planet. By the time of The Stinger, he's been trapped there for 87 days and gone mad from the isolation, but nonetheless vows to return to Earth.
- Tricked-Out Gloves: Before he switches over to finger-less gloves, he wears black gloves that have a device in them that scans footprints and lets him remotely control his robots, among other things.
- The Unfettered: Robotnik does what he feels and has no concern for the consequences.
- Un-person: At the end of the film, he is banished to another planet by Sonic, and upon doing so, the government, who never liked him anyway and only hired him because they had to, is quick to erase all traces of him from existence. When questioned about Robotnik by Tom, a military official says "no such person exists".
- Vile Villain, Saccharine Show: Despite being in a lighthearted buddy comedy film and having humorous qualities himself, Robotnik still stands out for being a cruel, unpleasant, sociopathic asshole with no redeeming traits.
- Villainous Breakdown: Throughout the film, he gets more and more frustrated by Sonic and Tom's ability to avoid him. At the finale, he really loses it. When his Berserk Button gets pressed by Tom, he loses focus, and Sonic banishes Robotnik to the Mushroom Planet with a Warp Ring as a result. There, Robotnik starts to Go Mad from the Isolation, complete with a Madness Makeover. In spite of that, Robotnik confidently vows that he'll find a way back and take his revenge on everyone.
- Villains Out Shopping: While examining the energy output of Sonic's quill, he happily dances to "Where Evil Grows" and accepts a latte from Agent Stone.
- Villainous Friendship: The closest thing he has to a friend is Agent Stone, and even then, Robotnik barely tolerates him, acting rude and contemptuous of him despite Stone doing everything Robotnik asks him to.
- Vocal Evolution: Throughout the film, Robotnik's voice is more or less Jim Carrey in Large Ham mode, but by the time of the ending, his voice has noticeably become a lot gravellier since his banishment to the Mushroom World. In fact, it comes off as quite an impressive impersonation of Eggman's traditional voice actor, Mike Pollock.
- What Measure Is a Non-Human?: Is more than eager to harvest an alien hedgehog for the sole purpose of making better robots.
- World's Smartest Man: As with the source material, Robotnik definitely sees himself as this, and can definitely back it up, given how much more advanced his inventions are than anything else in the world. This trope is the reason the government puts up with his incredibly unlikable personality.
- Would Hurt a Child: Throughout the movie, he is trying to capture and eventually kill Sonic, who is just a teenager.
- You Are What You Hate: Not only is Robotnik a human who looks down on other humans, he's also an even bigger bully than his childhood tormentors, given his own jerkass behavior and domineering personality.
- You Don't Look Like You: Subverted. In the first half of the film, Jim Carrey's Robotnik only vaguely looks like Eggman. He resembles Jim Carrey himself a lot more, but with a smaller yet cartoonishly styled brown mustache, as well as wearing a long black coat and square sunglasses in his initial scenes. He also has hair, something that the original Eggman never had. This changes over the course of the movie, seeing as he eventually wears his trademark red bodysuit and goggles later on, and finally appears like the game version with a shaved head and bushy dark red mustache in The Stinger.
Played by: Lee Majdoub, Carlo Vázquez (Latin-American Spanish)
Robotnik's right-hand man and a complete sycophant.
- Affably Evil: In stark contrast to his boss, Agent Stone bears no real malice towards the heroes and only opposes them out of duty.
- Anti-Villain: Despite being Robotnik's henchman, Stone never really does anything villainous and is shown to be quite a Nice Guy.
- Butt-Monkey: His only purpose is to be the doctor's punching bag both verbally and, in at least one instance, physically.
- Canon Foreigner: Created specifically for the movie.
- Expy: Being a polite human assistant that can put up with Robotniks abuse makes him a clear remember to Snively from Sonic SatAm
- The Dragon: To Robotnik, like many others from Sonic media before him but more competent.
- Harmless Villain: He doesn't seem to be a malicious guy, in spite of working for Robotnik. He doesn't do anything evil in the movie, and at one point disagrees with Robotnik that he should have chased down Sonic and Tom escaping from Robotnik's grasp since Stone retorted his first priority is his master's safety.
- Minion with an F in Evil: He seems a little too nice to be working for someone like Robotnik. When Sonic and Tom were fleeing from Robotnik, Stone's instinct was not to chase them but cater to his master and see if he's alright.
- Morality Pet: The only person Robotnik shows any form of kindness to as Robotnik compliments how he makes lattes and even makes a rock named Agent Stone on the mushroom planet showing he did miss Stone despite claiming he wouldn't miss him when they departed earlier in the film.
- Only Friend: As much as Robotnik treats Agent Stone like crap, he's probably the closest thing to a friend that Robotnik has. He compliments him when he gets him a latte that he likes and when he's stranded on the Mushroom Planet, he carves a rock in Agent Stone's likeness and lugs it around, in spite of his open contempt for people and inefficiency.
- Only One Name: His first name is never mentioned.
- Satellite Character: His role in the movie revolves entirely around serving as Robotnik's personal lackey.
- Translator Buddy: After Robotnik's long tirade toward Bennington, Stone sums up the doctor's opinion of the Major in five words:"The doctor thinks you're basic."
- Undying Loyalty: An absolute kiss-up to the doctor. Ironically, despite Robotnik complaining that humans are useless compared to perfectly obedient machines, Agent Stone does everything he's told without question or complaint.
- Villainy-Free Villain: Doesn't do anything truly villainous other than be with Robotnik who didn't do anything illegal or villainous ethier until he tried to kill Tom which Stone did not participate in.
- What Happened to the Mouse?: He's never seen again when Robotnik heads to San Francisco. It's implied he might have gotten arrested by the military.
- Yes-Man: He sucks up to Robotnik at all times, following his instruction without question.
Played by: Natasha Rothwell, Laura Torres (Latin-American Spanish dub)
- Bound and Gagged: Spends the remainder of her time tied up to a chair.
- Butt-Monkey: Rachel spends the entire second half of the movie tied to a chair where nobody, not even her own daughter, will listen to her. Given her nasty behavior, it's hard to blame them.
- Canon Foreigner: Like Tom and Maddie, she isn't from the games.
- Establishing Character Moment: Spells out "divorce" after a phone call between Maddie and Tom, establishing her objection to their relationship.
- Fainting: Upon seeing Sonic for the first time, Rachel barely has enough time to mutter "Oh, help me, Jojo!" and ask somebody to catch her before passing out.
- Hate Sink: She seems to exist solely to hate Tom, urging her sister to divorce him for no given reason (before he becomes wanted by the government) and be a loud contrarian. She never even comes around by the end but since the couple are continuing their life in Green Hills it's a non-issue.
- I'm Standing Right Here: Tom and Maddie discuss commandeering Rachel's car among other things while Rachel is tied to a chair and listening to their entire conversation. Their inflections imply that they wanted her to hear them since she's been such a pain in their side about their relationship.
- Irrational Hatred: Why she dislikes Tom so much is never really explained.
- Jerkass: At least Robotnik has an amusing charm about him and one Pet the Dog moment. There is really nothing appealing about Rachel in the meanwhile.
- Obnoxious In-Laws: She doesn't like Tom, to put it nicely. Even before he became a fugitive, she would jump on any flimsy excuse to tell Maddie to divorce him. She becomes so obnoxious that she has to be tied up to a chair to stop her from being a nuisance.
- Only One Name: Her last name is never mentioned.
- Red Herring: Towards the beginning of the movie, a scene with Maddie's sister Rachel (who hates Tom and constantly tries to convince Maddie to divorce him) and a meaningful-looking shot of Robotnik's drone riddling a photo of Maddie and Tom with bullets suggests that the shenanigans of the movie might put a strain on Maddie and Tom's relationship.
- Sassy Black Woman: A black woman who's too fussed up about wanting to separate her sister and brother in-law.
- Ship Tease: Gets this with Officer Wade Whipple in a deleted scene when he starts flirting with her.
- Sibling Yin-Yang: With Maddie. Maddie is a Nice Girl and Happily Married, but Rachel is obnoxious and implied to have had a divorce with her husband.
- Villainy-Free Villain: Although she isn't actively antagonistic and doesn't do anything villainous, she's still an unlikable asshole.
Played by: Melody Niemann, Abril Gómez (Latin-American Spanish dub)Tom and Maddie's niece and Rachel's daughter. She befriends Sonic and helps by giving him new shoes.
- Canon Foreigner: Like Tom and Maddie, she isn't from the games.
- Cheerful Child: She doesn't seem all that bothered by Sonic's appearance, especially compared to her mother. On top of that, she also gives Sonic his new shoes after seeing that the ones he has are worn out, all so that Sonic wouldn't hurt his feet anymore.
- Disappeared Dad: Her father doesn't appear and isn't even mentioned. In Jojo's drawing you can see in the background, there's only her and her mother.
- Friend to All Living Things: She immediately bonds with Sonic and helps him by giving him new shoes.
- Like Parent Unlike Child: She has none of Rachel's obnoxious characteristics. While her mother antagonizes Tom at every opportunity, Jojo is a sweet girl who is happy to see him goes out of her way to be kind to Sonic.
- Nice Girl: She becomes one of Sonic's friends and is the one who gives him his iconic shoes.
- Nice Shoes: Jojo sees how horribly worn-out Sonic's sneakers are, and gives him a new pair which are red with one single white stripe that look like his trademark sneakers from the games.
- Only One Name: Her last name is never mentioned.
Officer Wade Whipple
Played by: Adam Pally, Noé Velázquez (Latin-American Spanish dub)
- Alliterative Name: Officer Wade Whipple.
- The Dog Bites Back: After Robotnik abuses him earlier in the film, Wade leads the people of Green Hill to fight back against him.
- Let's Get Dangerous!: When Robotnik is about to kill both Tom and Sonic, Wade stops him by firing near his head.
- Sarcasm-Blind: Wade's Establishing Character Moment is being oblivious to two of Tom's sarcasm in a row.
- Ship Tease: Gets this with Rachel in a deleted scene when he starts flirting with her.
Played by: Frank C. Turner, Alejandro Villeli (Latin-American Spanish dub)
- Cassandra Truth: Before Sonic hides out in Toms garage, hes the only one who believes in Sonics existence.
- The Cuckoolander Was Right: Despite being a crazy old man who lives in the woods, Carl's absolutely right in his belief that there's a "Blue Devil" that roams across Green Hills.
- Friendly Enemy: Sonic views him as this, saying they have fun. Turns out he sees Sonic the same way, standing up against Robotnik when he threatens him.
- No Mere Windmill: No one believes him about the "Blue Devil" around town. Turns out, Crazy Carl was right. (Sort of; Sonic isn't actually a devil.)
- Terrible Artist: He creates an Artist's rendering showing the Blue Devil. It's a terrible Sonic picture...but a great Sanic picture.
