Eggman Empire

    open/close all folders 

    Dr. Ivo "Eggman" Robotnik 
"I know, I say that every time, but this time, really, nothing will stop me!"

Voiced by Masaharu Sato (SegaSonic the Hedgehog), Junpei Takiguchi (Japanese, OVA), Chikao Ohtsuka (Japanese, Sonic X, 1998-2015), Edwin Neal (English, STH: The Movie), Deem Bristow (English, 1999-2004), Mike Pollock (English, Sonic X, 2005-present)

The Big Bad of the series. The portly scientist who's one desire is to rule over everyone and everything using his technology. Eggman doesn't have a significant background, but he did seemingly look up to his grandfather, Gerald Robotnik. Although other sources claim he used to be a kind doctor before a freak accident warped his personality. Eggman's plans almost never change, and he's always willing to pull out all of the stops to accomplish his goal.

Eggman may possess a high IQ, but his personality is far from mature. He wants things his way, and is very temperamental when denied as such. However, despite his immaturity, he's every bit as clever as ever, able to create almost anything for his goals, and possess quite a bit of cunning and planning to carry them out. If there's one that that stands out about the doctor however, its his ego, which may only be rivaled by his long time nemesis, Sonic the Hedgehog.

If you want to hear his take on all this, click here.

  • Ace Pilot: Considering the number of Humongous Mechas he's piloted over the years and the number of times he's shot down Tails's plane, he fits this to a T.
  • Acrofatic: Eggman is very athletic and can outrun Sonic, despite his rotund appearance.
  • Aesop Amnesia: From Sonic Adventure through Sonic Unleashed, he never seemed to learn that Evil Is Not a Toy. He seems to have recently learned in Sonic Colors.
    • In Sonic Generations, he finally manages to harness the power of a Cosmic Horror without losing control of it at any point. Though it did help that the Time Eater was out of commission when he came upon it.
    • And again in Sonic Lost World, he manages to take control of The Deadly Six, a group of six powerful Zeti and keep them in line with the Cacophonic Conch and he only loses control of them because Sonic impulsively kicks the conch out of his hand. It seems he's getting better with experience.
  • Affably Evil: Despite really wanting to Take Over the World (and occasionally going to some extreme lengths to achieve this goal), Eggman's a fairly pleasant fellow who treats his enemies with respect. Well, most of the time.
    • In the Heroes manual, he's described as a romantic and a feminist, as well as being a self-professed gentleman.
      • Said manual then points out that it's a tad hard to see such qualities behind the maniacal laughter often accompanying his announcements of Global Domination.
    • In Colors, he takes Sonic's advice regarding threatening him directly rather than going through a bunch of terrible amusement-park-related puns on the way — for which Sonic then thanks him.
    • In Sonic Lost World, he saves Tails' life from rogue Cubot, even though it isn't necessary for his master plan, and seems to genuinely respect Tails. He's a complicated guy.
  • American Kirby Is Hardcore: In Japan, he was always the Affably Evil Egg-themed Eggman with silly animations and a happy disposition, but for most of his American history (not counting AoStH), he was sinister and considered a huge threat. Nowadays, he seems to be a strange mix of the two personalities.
  • Anti-Villain: In Sonic X, at least. Arguably more an Affably Evil villain early on, but by the third season, his role as true villain is all but gone.
    • Was arguably in this trope in Sonic Heroes, as it is heavily implied that he regretted the outcome of Metal Sonic revolting against him.
  • Appropriated Appellation: "Eggman" was introduced stateside as a mocking nickname, but he seems to have embraced it.
  • Arch-Enemy: To pretty much the entire cast, but to Sonic in particular. They've been going at it long before any other character showed up.
  • Arson, Murder, and Jaywalking: An early Archie Comics description of him described him as Supreme Dictator, Industrial Polluter, Meglomaniac, Corrupt Politician, Underhanded Reprobate, Rainforest Ravager, Puppy Kicker, Oil Spill Coordinator, Holiday Hater, and an Insurance Salesman.
    • And it happens again in Sonic Lost World. When the Deadly Six fail to beat Sonic, he angrily lists the things he's done for them.
    Eggman: I hone your abilities. I equip you with the most powerful mechs I can create! I even give you a giant sandwich! And you still disappoint me!
  • Art Evolution: Eggman has been redesigned more than any other character in the entire series, even Sonic himself! Bonus points for his retro design reappearing in Generations.
  • Awesome McCoolname: Doctor Ivo Robotnik.
  • Badass: As goofy as he can be, Eggman has come quite close to taking over the world multiple times.
  • Bad Liar/Suspiciously Specific Denial: Claiming that his amusement park was created to make up for his past transgressions and is in no way secretly covering up an evil scheme.
  • Bald of Evil: He is bald, and he is evil, so....
  • Batman Gambit: He's pulled off quite a few over the years.
    • In the Movie. He lures Sonic to Robotropolis by claiming a villain named Metal Robotnik had taken over and that the generator powering it was set to overload. In reality, it was a ruse to lure Sonic there to copy his data and activate Metal Sonic.
    • In Sonic Chronicles. He pretends to have undergone a Heel-Face Turn and helped Sonic and the gang until they left for the Twilight Cage allowing him to take advantage of its Year Outside, Hour Inside properties and build up his army.
    • In Sonic Unleashed. He built a fleet in outer space to lure Sonic there so he could drain the energy of the Chaos Emeralds to power his cannon and shatter the earth, freeing Dark Gaia.
    • In Sonic Lost World, after the Deadly Six turn his Badniks against him, he immediately devises a plan to turn things back in his favor by using Sonic to defeat the Zeti and allow him to use a giant robot to finish off his nemesis.
  • Big Bad: The most prominent and consistent villain of the series. Even if he would lose his status depending on the game, Eggman always manages to bounce back into this role eventually.
  • Black Eyes of Crazy: In the Adventures of Sonic the Hedgehog, Sonic Underground, and Sonic SatAM animated series.
  • Broken Pedestal: The reason he became a scientist is because he admired his grandfather and wanted to be a great scientist like him. Yeah...
  • Card-Carrying Villain: Eggman makes absolutely no pretense about the evil he does and he even revels in it, especially in Generations and Adventure.
  • Catch Phrase: Eggman is well known for having a certain phrase that he repeats over and over again in his boss fights in several games.
  • Cheshire Cat Grin: His emblem and himself have this.
  • The Chessmaster: He obtains all the Chaos Emeralds in Adventure 1 by showing up where the various characters are and often surprising them by just taking the emeralds from them. Also see Batman Gambit and Dangerously Genre Savvy below for more instances where he is this trope.
  • Classic Villain: Representing Ambition, Pride and occasionally Wrath.
  • Dangerously Genre Savvy: Despite Eggman's ego and childish personality, he has shown on occasion that he has the capacity to plan ahead.
    • In Sonic Adventure, he plays off the fact that Sonic is going to be collecting the Chaos Emeralds by telling his plan ahead of time, and then intercepting him whenever Sonic found a new emerald. He plays off of Knuckles' worst character trait to provoke a fight between him and Sonic and get two more emeralds. Lastly, he anticipated his plans blowing up and had planned to nuke Station Square just in case.
    • In Sonic Adventure 2, he discovers that the heroes have two Chaos Emeralds but correctly deduces that one of them must be fake due to Eggman having the other six and puts forth a plan to get the last emerald out of their hands. The result is that he nearly kills Sonic after launching him from the Space Colony Ark. And even after he's defeated by a grieving Tails, he still manages to make off with the real emerald anyway.
    • In Sonic Chronicles. He anticipated that he would be defeated during the fight on his Egg Carrier and planned ahead by calling a Med Bot to pull him from the wreckage and nurse him to health. He also took full advantage of the Nocturnus Clan invasion by pretending that he had undergone a Heel-Face Turn and helped Sonic and co. along until they left for the Twilight Cage. Knowing full well about the Twilight Cage's Year Outside, Hour Inside properties, he used the time to rebuild Metropolis and build up his army. And thanks to the game's Cliff Hanger ending, He practically won!
    • In Sonic Unleashed. Prior to the game, he kidnapped Professor Pickle for his research on Dark Gaia and concoted a scheme to awaken the beast. He set up a massive fleet in outer space to lure Sonic, knowing full well Sonic would plow through his defenses as Super Sonic. He then begged for mercy once it looked like Sonic had foiled his plans again... only to trap Sonic in a device that drained him of all of his power, forcefully taking him out of Super Sonic form and using the Chaos Emeralds energy to power his cannon and shatter the earth, awakening Dark Gaia. When his plan doesn't go the way he liked due to awakening Dark Gaia too early, he immediately comes up with a plan B: draw all the Dark Gaia monsters to his base and put Dark Gaia back together to harness its energy to create Eggmanland.
    • In Sonic Colors. Despite foolishly leaving the key in the elevator and allowing Sonic and Tails to infiltrate his Interstellar Amusment Park, Eggman tries his best to distract Sonic and keep him in the dark about his plan to build a Mind-Control Cannon. Though he fails to stop Sonic from destroying all his generators, Eggman still had enough energy to power his machine. In fact, the only reason his plan didn't work was because Sonic's fight with the first boss caused its arm to get stuck in the cannon, causing it to backfire when he activated it.
    • In Sonic Lost World. Prior to the game, he traveled to the Lost Hex, encountered the Deadly Six, and used the Cacophonic Conch to keep them under his thumb and use their abilites for his plans. His plans inevitably fall apart when Sonic kicks the conch away, but even then he's still showing remarkable Genre Savvy. His backup plan was to team up with Sonic and Tails, knowing that they would eventually defeat the Six, and later faked his death so he could shut down the Extractor and power up his mech using Earth's energy. To put this into perspective, despite his plans unraveling completely, he managed to claw his way back to the title of Big Bad and Final Boss with nothing but determination and cunning. Nice to see you back, Eggman.
  • Deface of the Moon: He blows up half the moon in Sonic Adventure 2. It's still like that; we're just seeing the good side.
  • The Determinator: You do have to give him credit, for no matter the setbacks, he'll always try to defeat Sonic. Deconstructed in the Archie comics during Ian Flynn's run; there, the constant setbacks were slowly cracking his mind until issue 200, in which he finally suffers from a completely disturbing and realistic Villainous Breakdown. However, not long afterwards, he recovers from said breakdown by reasoning himself out of it.
  • Dirty Old Man: In the Movie, he planned to marry Sera after Metal Sonic destroyed Planet Freedom. Keep in mind that Eggman is in his fifties and Sera is a teenager.
  • Ditzy Genius: He has an IQ of 300, but is simultaneously very childish.
  • Dub Name Change: From "Eggman" to "Ivo Robotnik". Eventually, due to the western continuities becoming obsolete once Adventure came out, they eventually decided to name him "Robotnik" (with "Eggman" as a nickname) in all versions.
  • Egopolis: Eggman wants to create Eggmanland, a city bearing his likeness. In Sonic Unleashed, he succeeds at this.
  • Emperor Scientist: He controls the Egg Empire and Eggmanland.
  • Even Evil Has Standards: Frequently downgraded to assisting the heroes, lest an even crazier person tries to destroy the planet. Is also genuinely horrified when he learns that Gerald Robotnik apparently sold out his home planet to Black Doom for the sake of research.
    • In "Sonic X", when he catches Black Narcissus torturing Chris Thorndyke and Cosmo, Eggman was upset at Narcissus's actions, explaining that "it's one thing to threaten people and take them prisoner, but when you actually hurt them, that's going too far."
    • In Sonic Rush Adventure, He freaks out when Eggman Nega activates the Egg Wizard's Planet Buster Laser in a last ditch effort to defeat Sonic and Blaze.
    • In Sonic Unleashed. when Chip states that Eggman might be starving Professor Pickle when he had him imprisoned, Tails remarks to Chip that Eggman's most likely going to be feeding him while imprisoned, as "even he isn't that cruel." Of course, that's not saying that the food is actually edible, but still.
    • In Sonic Lost World, he's appalled at how the Deadly Six wish to outright destroy Earth instead of conquering it.
  • Even Bad Men Love Their Grandpas: He has a deep respect for his grandfather, Gerald Robotnik, and it is heavily implied that he may have desired to conquer the world because he felt that his grandfather was unjustly arrested.
  • Evil Counterpart: To Tails in several ways, especially in Sonic Adventure 2.
  • Evil Genius: What did you expect?
  • Evil Is Bigger: He stands at an impressive 6'1", which is far taller than Sonic and most of his friends. Only Vector comes close at 5'10", and Big the Cat surpasses him at 6'6".
  • Evil Is Hammy: Especially in Japanese and with Mike Pollock.
  • Evil Is Not a Toy: In many of the 3D games from Sonic Adventure through Sonic Unleashed, he's displaced by the evil he's unsealed as the Final Boss. By Sonic Generations, Evil is a Toy.
    • And back again in Sonic Lost World, though ironically it was Sonic's fault in that case. Regardless of this trope, he still manages to be the game's final boss.
  • Evil Virtues: Hard worker and a lifelong admiration of his grandfather, Professor Gerald Robotnik. Word of God also states Eggman as a wannabe feminist with a hidden romantic side, though we never see it in action. On that note, judging by two Freeze-Frame Bonus moments in Sonic Unleashed, Eggman is also a fan of the Sega Dreamcast, carrying it with him all the way to Sonic's battle with Dark Gaia.
  • Failure Is the Only Option: He never succeeds at any of his plans, either due to Sonic getting in the way, or because whatever force he's using spirals out of his control. Eggman Nega in Sonic Rivals reveals that he will never succeed, and that his failures ruin the Robotnik name.
  • Fat Bastard: Is grossly obese and endorses animal cruelty.
  • Fat Idiot: Inverted: Eggman, though bumbling and slightly unstable, is a technological genius.
  • Faux Affably Evil: Most of the more ruthless alternate incarnations (e.g. the SatAm and Archie comic interpretations) at least have some moderate goofy or whimsical traits.
  • For the Evulz: Some alternate interpretations, particularly the StC and SatAM versions, revolve many of their plans or pasttimes on the suffering of innocents. The games and Sonic X versions are more toned down, though they do retain Card-Carrying Villain traits on occasion.
  • Four Eyes, Zero Soul
  • Future Me Scares Me: "Wow. Will I really get that crazy?"
  • Galactic Conqueror: Nearly mind-controlled the entire universe using the Wisps' Hyper Go-on energy.
  • Game Over Man: While not explicitly appearing on the Game Over screen, the Megadrive game endings depict Eggman taunting you if you missed some Chaos Emeralds. (In Knuckles' Sonic 3 quest, this role is filled by Eggrobo/Metal Sonic.)
  • Gasshole: According to Sonic in Sonic Colors.
  • Get Back Here Boss: Most boss fights with Eggman involve him piloting a robot and running away from Sonic.
  • Goggles Do Nothing: In his Sonic Adventure tenure.
  • Goggles Do Something Unusual: In '06, his shades are shown to house a heads-up display.
  • Gonk: Looks rather cartoonish compared to other humans in the series.
  • Graceful Loser: At least compared to some other villains.
  • Hijacking Cthulhu: This has been a running theme with Dr. Eggman since Sonic Adventure. It wasn't until Sonic Generations that he actually succeeded without it backfiring.
  • Humongous Mecha: Has piloted many over the years.
  • Image Song: "E.G.G.M.A.N.". More recently, he's had a Leitmotif used in three successive games - Sonic 06, Sonic Unleashed, and Sonic Colors.
  • Informed Attribute: He's apparently a feminist. Flat-out contradicted in Sonic Rush, as when Blaze confronts him for the last Sol Emerald, he says that he "never thought a girl could be so tough".
  • In-Series Nickname/Insult Backfire: How the "Eggman" moniker was adapted for the English audiences, starting with Sonic Adventure. It was supposed to be in mockery, but for some reason, it's all he goes by these days, even when referring to himself, almost to the point that the "Robotnik" name no longer has relevance (the only way it stays relevant is through his grandfather, Gerald Robotnik).
  • "I Am" Song: Aptly titled 'E.G.G.M.A.N.'
    "I am the Eggman! It's what I am, I am the Eggman, I got the master plan!"
  • It's All About Me: Not only does he paste his own face onto almost all of his creations, he wants the entire world to admire him and his brilliance.
  • Japanese Pronouns: "Washi".
  • Jerkass: In the more comedic literations.
  • Jerk with a Heart of Jerk: Even when he acts like he is willing to save even his enemies, all that he really cares about is himself and his own power at the end.
  • Lampshade Hanging: Not by himself, but the lyrics of his boss theme in the Japanese soundtrack of Sonic CD references his Bald of Evil as well as one of his more defining traits of being an Evil Genius.
  • Large Ham: He's this in general, especially in Adventures of Sonic the Hedgehog.
  • Laughably Evil
  • Leitmotif: Has multiple, such as "Theme of Dr. Eggman" in the first Sonic Adventure and "E.G.G.M.A.N." in Sonic Adventure 2.
  • Lethal Chef: In Sonic Unleashed, Professor Pickle complained about the food he served, and neither Sonic or Chip enjoy eating anything from Eggmanland.
    • In Sonic Colors, Tails apparently paid an ill-advised visit to the Bucket O' Sushi food stall between cut-scenes. His only comment on the experience? "His cruelty knows no bounds".
  • Let's Get Dangerous: In Sonic Adventure, during the Grand Finale for Tails's campaign, Eggman drops his usual Large Ham personality in favor of a more calm, composed, surprisingly frightening demeanor in the moments before he fights Tails in his giant robot.
  • Mad Scientist: Of course. Though, compared to his grandfather Gerald (after Maria died), and his descendant Eggman Nega, Eggman is arguably the least insane of the three.
  • Malevolent Mugshot: Eggman must be proud of his work, because he stencils his cartoon mug on all of his inventions. The Death Egg even sported a giant mustache.
    • There seems to be some history behind this. The Space Colony ARK in Adventure 2 bears a similar visage when the Eclipse Cannon is revealed, but there's no way Eggman contributed to that, since his grandfather was the last person to set foot on the station.
  • The Man Behind the Man: He and Eggman Nega pull this off in Sonic Rush Adventure, being the ones who created Captain Whisker and his crew to steal the Jeweled Scepter.
    • And he pulls it off again in Sonic Generations, teaming up with Classic Eggman to use the Time Eater to erase their previous defeats at Sonic's hands.
  • Man Child: His idea of Eggmanland is an amusement park.
  • Manipulative Bastard: He has manipulated Knuckles repeatedly (though by the fourth time or so, it might be more Knuckles' fault) and even tricked Tails into revealing he had a fake Chaos Emerald. Also, he tricked Sonic into getting in the center of his ray to unseal Dark Gaia.
  • Mean Character, Nice Actor: Eggman's current English VA, Mike Pollock, is very friendly and likes to keep in touch with fans.
  • Meaningful Name: Besides "Eggman" aptly describing his appearance, his full name Ivo Robotnik is meant to be this; the first name 'Ivo' was picked because of the phonetic similarity to the word 'evil' (some drafts of the unpublished US Sonic Bible also specify that it should be pronounced "ee-vo", rather than "eye-vo" as it is usually pronounced in English). In addition, Ivo is the reverse of Ovi, which is the genitive singular form of the Latin word ovum, meaning egg. The term robotnik is derived from the Czech words for "work" and "forced labor" and an older Slavic term for "slave." Given he imprisons animals inside capsules and his killer robots on a regular basis, his name thus makes him out to be an "Evil Slave-Driver".
  • Morally Ambiguous Doctorate
  • Motifs: Eggs. It's in his name, and every one of his creations' names.
  • Nice Job Fixing It, Villain: In Sonic 2006, every time Silver attempts to kill Sonic, Eggman kidnaps Elise. In a way, he actually saved the world, as Sonic being killed in front of Elise would have had far worse ramifications, as the Final Story revealed.
  • No Celebrities Were Harmed: His earliest design was a caricature of president Theodore Roosevelt.
  • Noblewoman's Laugh: Particularly in the anime.
  • Not-So-Harmless Villain: Yes he's a Ditzy Genius who never seems to learn that Evil Is Not a Toy. But it's made clear time and time again throughout the series that if Sonic wasn't his adversary, he'd be ruling the world right now.
  • Obviously Evil: His morbidly obese physique, gaudy villainous mustache, his ego-driven habit of putting his face on anything he owns, and his aforementioned meaningful name go hand-in-hand with his Card-Carrying Villain stature.
  • Off Model: In Sonic the Fighters, in the final fight against him, he is inexplicably smaller than Sonic!
  • OOC Is Serious Business: Eggman's default setting is Large Ham, but it's when he stops being a Large Ham that lets you know he is pissed. See Tranquil Fury below.
  • Opaque Lenses: Eggman's blue pince-nez glasses.
  • Paper-Thin Disguise: Wears these in Sonic Shuffle and the Sonic X comic.
    • Sonic accuses King Sharyar of doing this in Sonic and the Secret Rings, only to find out it's not Eggman. Then again, Sonic did this to almost everyone in the Sonic Storybook Series, but starts to get used to it eventually, only briefly confusing the blacksmith for Tails and then only stating that Gawain reminds him of Knuckles and not even mentioning Percival's resemblance to Blaze.
    • He also tried this in Sonic Free Riders, disguising himself as King Doc in an attempt to steal the contestants' racing data for his own Extreme Gear. Needless to say, none of the characters fall for it.
  • Person of Mass Destruction: In all of Eggman's schemes, he always manages to cause horrendous collateral damage, either directly or indirectly due to whatever Cosmic Horror spirals out of his control.
  • Pride: As shown in Sonic Lost World, he is capable of planning around Sonic being able to defeat other threats to his plans. However, he seems to have a constant inability to accept Sonic always being able to defeat him, which results in him always getting defeated.
  • Red and Black and Evil All Over: His outfit.
  • Red Eyes, Take Warning: In most of the American/European non-game media, he is depicted with red eyes and black irises. In the games, though, he has normal blue eyes hidden behind his glasses.
  • Red Oni, Blue Oni: Is the red oni to Tails and Sonic.
  • Robot Master: Creates tons of robots and mechs.
  • Scarf of Asskicking: Wears one in the Sonic Riders series.
  • Scary Shiny Glasses: Manages this every once in a while, usually with a massive, toothy grin.
  • Sinister Shades: The above-mentioned glasses.
  • Strong Family Resemblance: He looks a lot like his grandfather Gerald, and his descendant Eggman Nega looks exactly like him, sans the white mustache.
  • Stout Strength: On and off, he's shown to be stronger than he appears, smacking a giant robot's hand away with his stomach, and punching a(n albeit small) defense turret off the wall with his bare hands. Sonic Lost World has him punch through a wall of solid ice without so much of a scratch.
    • He's also defined as a Power class in Sonic Riders, being able to punch out walls, cars, and even trains along the track.
  • Surrounded by Idiots: Robotnik's AoStH robots.
    • Also his robots Orbot and Cubot in recent games beginning with Sonic Colors.
  • Take Over the World: What he wants to do in most installments/adaptations.
  • Terrible Trio: Outside of the games, he formed one with Scratch and Grounder and Decoe and Bocoe. In the games, he forms one with Orbot and Cubot.
  • Took a Level in Badass: In Sonic Adventure 2 in his plots, going so far as to take hostages. Even partly lampshaded by our boy in blue.
    Sonic: "You turned into a BIG TIME villain, doctor."
    • In Sonic Unleashed, he captured Sonic in his super form and drained his Emerald energy to power a machine that detonates the planet!!! Meanwhile, in Sonic Colors he creates a gargantuan space station that chains multiple planets together so as to capture aliens to power his machinery (with not a single treacherous Eldritch Abomination in sight).
    • He goes through another level in Sonic Generations, where he, yet again, gets ahold of an Eldritch Abomination. Only this time, he manages to keep it under control without it betraying him!
      • Another way of putting it is that Eggman, despite becoming a more comical villain, had become capable of a Class X Apocalypse How in Sonic Unleashed, then a Class X-2 in Sonic Colors, and finally a Class Z in Sonic Generations.
    • Sonic Lost World has him gain control of six very powerful Zeti and take measures to prevent their betrayal. His control over them is so great, he only loses control thanks to Sonic. And that's not even mentioning him punching through a screen of ice and devising a plan to use Sonic to defeat the Deadly Six and regain his status as the Big Bad.
  • To The Bat Noun: His weapons, vehicles, and a good amount of his Mecha-Mooks will inevitably have "Egg" in their name.
  • Trademark Favorite Food: EGGman has a lot of egg-themed robots and vehicles. This obsession is so strong that his most powerful weapon was the Death-EGG.
    • Robotnik had eggs in Adventures of Sonic the Hedgehog EVERY DAY FOR THE LAST 10 YEARS. He apparently never got sick of that diet, so much so that he assaults Scratch and Grounder when they give him Hotcakes instead of his daily serving of eggs.
    • He also apparently likes sub sandwiches, as he eats a whole one in just a few seconds in Sonic Unleashed.
  • Tranquil Fury: Eggman is a Large Ham by default, but there are few times he will drop the Large Ham part in favor of being dead serious.
    • In Sonic Adventure after Chaos 6 is defeated and his Egg Carrier crashes, he tries to fire a missile at Station Square in a desperate attempt to salvage something from having his plans completely fall apart in the last few hours. The missile, unfortunately, is a dud and Eggman has to detonate it manually, but Tails beats him to it and disables it. Eggman, though extremely pissed, barely raises his voice as he threatens to make Tails pay before summoning his Egg Walker.
    • And again in Sonic Lost World. When Zavok and Zazz taunt Eggman about how the energy from the Extractor is making them stronger, Eggman threatens to destroy everything they love in the most chilling voice possible before smashing the ice wall they were speaking from.
  • Vague Age: Unlike most of the heroes, Eggman's age has never been stated.
    • He's supposedly in his fifties, though. He'd have to be to remember his grandfather.
  • Victory Is Boring: In Sonic X, he starts crying out for Sonic's attention when he doesn't return to their home world for several months.
  • Villain Decay: Starting with Sonic Adventure and continuing throughout most games since, Eggman has been consistently overthrown as the main antagonist by a kind of all-powerful Bigger Bad, due to his own evil schemes frequently involving awakening said power to harness it to take over the world. Starting with Sonic Colors, however, it appears he's recovering and has begun to reclaim his mantle as the series Villain.
  • Well-Intentioned Extremist: The little known details about his planned Eggman Empire apparently involve scientists as the high class citizens, indicating that it is essentially the scientist version of Outer Heaven. If it is true that his world domination plans stemmed from the perceived injustice of Gerald Robotnik's arrest, that might give him an understandable reason for desiring this.
  • What Could Have Been: He was initially designed to be the hero — his initial concept was "Theodore Roosevelt in pajamas".
  • You Meddling Kids: "I hate that hedgehog!", his Catch Phrase from his Adventures of Sonic the Hedgehog portrayal, which gets the occasional Mythology Gag in other continuities.

    Metal Sonic 
"Sonic... I was created for the sole purpose of destroying you. But I can never seem to defeat you! That is why, I transformed my own body with my own hands."

Debut: Sonic CD

A recurring robotic replica of Sonic, designed to not only match but exceed his speed and power in every way. Despite constant defeat, he is a stubbornly persistent recurring foe of Sonic who, while initially just another mindless badnik, slowly gained a vengeful, egotistical personality over time, which prompts him to disobey his creator on a few occasions in the past if it serves his needs.

Voiced by Masami Kikuchi (Japanese, OVA), Junichi Kanemaru (Japanese, games), Gary Dehan (English, STH: The Movie), Ryan Drummond (English, 2004)

  • Accidental Pervert: In the OVA, Sonic deals a blow to knock Metal's head in the bottom of Eggman's machine, only for Metal to look up beneath Sera's dress. Made worse considering his telepathic bond with the real Sonic.
  • Adaptational Badass: While the mainstream Metal is no joke even with his overinflated ego in Sonic Heroes, his OVA counterpart is much more powerful, being a literal Person of Mass Destruction who flat out curb stomps Sonic in their first fight. And though Sonic fares much better in their second fight, Metal still had the upper hand. Had Tails not messed with his programming, Metal would have won.
  • Adaptational Wimp: Prior to the continuity reboot, the Archie Comics Metal Sonic was barely any more threatening than a typical robot and got whooped in every fight it had with Sonic, and was an assembly line series of robots devoid of personality. Both fans and even Sega got tired of this, and this prompted Archie to retool Metal to be more in line with the robot from the games in terms of prowess as of the series reboot.
  • A God Am I: In Heroes.
    Metal Overlord: "See me as I am, no longer afraid of anything! I shall become the ultimate overlord, ruling as the world's most supreme being!"
  • A.I. Is a Crapshoot: It's generally assumed that Robotnik made an upgrade to Metal that made him go mad with power and ego in Heroes. To elaborate, Metal deluded himself into believing he was the real Sonic, and that Sonic was his "loathsome copy"!
    • In the Movie/OVA, his programming is based on Sonic's mind. After a while, this eventually becomes a crapshoot in the other direction, and he does things the real Sonic would do.
  • All Your Powers Combined: As part of his DNA copying in Heroes. He gets the speed, power, and flight of Team Sonic, as well as Shadow's Chaos powers (particularly Chaos Control) and Chaos' shapeshifting abilities (via Froggy and Chocola), with his lines implying that he successfully copied all pertinent data from the rest of the cast.
    Metal Madness (to Team Chaotix): "You're all useless now that I've copied all your data."
  • Amplifier Artifact: The gem he finds during Episode Metal, which enhances his powers significantly and lets him fire lightning blasts from his hands.
  • Arch-Enemy: His literal sole purpose is to kill Sonic and replace him as the only Sonic around.
  • Art Evolution: The original design is more simplistic and puppet-like, while his post-Sonic Adventure 2 design gave him a little more detail and played with his proportions a little.
  • Ax-Crazy: Depending on the game.
  • Badass: One of the few characters who can match Sonic in skill.
  • Badass Automaton: One of Eggman's best (if not the best) robots, capable of both matching and in some regards exceeding Sonic.
  • Badass Baritone: When he's Suddenly Voiced in Sonic Heroes, but as mentioned below, it's Sonic's voice with an electronic makeover.
  • Badass Boast: Lets out plenty of these during the fight with Metal Madness.
  • Badass Longcoat: Neo Metal Sonic sports one in Heroes.
  • Batman Gambit: The entire plot of Sonic Heroes was one big Batman Gambit. He issued a challenge to Team Sonic while impersonating Eggman just to copy their data and defeat them. What makes it so unique is that he was only after Team Sonic. Team Dark, Team Rose, and Team Chaotix got involved by themselves, but it still worked in his favor.
  • Big Bad: In Sonic Heroes.
  • Bishonen Line: His "Neo" form in Heroes is distinctly more humanoid than his CD look.
  • Breakout Villain: He went from a boss battle in Sonic CD, to the most iconic villain in the franchise next to Eggman thanks to fandom popularity.
  • Card-Carrying Villain: In Sonic Heroes, due to his massive ego.
  • Characterization Marches On: Initially, Metal was just a well constructed but otherwise mindless knockoff of Sonic. Then Sonic Heroes gave him a personality, revealing him to be a cold-blooded, domineering egomaniac. Even after Eggman's subsequent reprogramming of him after his defeat, Sonic Free Riders shows that he still has enough persona to willingly go behind Eggman's back and study the other racers in disguise, all just to challenge Sonic to a one-on-one race.
  • Chest Blaster: His Plasma Pulse Attack in Knuckles Chaotix. Metal Overlord can fire cyrstals from the hole on his chest.
  • Co-Dragons: With Bass in the Sonic the Hedgehog/Mega Man: Worlds Collide series.
  • Cool Plane: Pilots one in Sonic the Hedgehog 4
  • Conjoined Eyes: Being based on Sonic, he follows the hedgehog design scheme.
  • Costume Copycat: Disguised himself as Eggman for the majority of Sonic Heroes. The real Eggman gave orders to Team Chaotix during that time in order to free himself.
    • Also repeated in Sonic Free Riders, where he disguised himself as a blue E-10000 in order to copy everyone's data and prove himself the best user of Extreme Gear.
  • Crippling Overspecialization: He was created to exceed Sonic's speed, which he does very well due to having a jet engine sticking out of his torso. However, since this causes him to outright fly, he often has trouble stopping.
    • In addition, that kind of speed puts a huge strain on his insides — Metal Sonic is prone to overheating after traveling faster than Sonic for too long, when he has to spend time to cool down. In Sonic Generations, this is his one biggest weakness.
  • A Day in the Limelight: A mini-Episode of Sonic 4 focuses on his return after his defeat in Sonic CD. He's even the playable character.
  • Determinator: His resolve is almost as strong as Sonic's. No matter how long it takes or how many defeats he suffers, he will defeat Sonic. To quote his only line of dialogue from Generations:
    "I WILL BATTLE YOU AS MANY TIMES AS IT IS NECESSARY."
  • Disney Villain Death: Subverted. He falls several thousand feet from the sky when defeated as Metal Overlord, but he survivies.
  • The Dragon: To Eggman when Orbot and Cubot aren't filling the role.
  • Dragon with an Agenda: Despite being programmed to serve Eggman, his drive to defeat Sonic tends to override his loyalty to Eggman. This is especially shown in Sonic Free Riders where he goes behind Eggman's back and disguises himself as a blue E-10000 to copy everyone's racing data.
  • Dragon Ascendant: In Heroes, he locks Eggman in a room and decides to conquer the world for himself. Unfortunately, he's defeated and—
  • Evil Knockoff: Provides the trope image. However, in Heroes, his desire to prove himself to be better than Sonic had progressed to the point that he thought he was the real deal.
    Metal Overlord: "Guooooo! Why?! I had it all! I am the ultimate overlord, Metal Sonic. I am the real Sonic!"
  • Evil Is Petty: His entire plan and motive in Sonic Heroes evolved out of his desire for revenge on Sonic for losing to him so many times.
  • Evil Sounds Deep: In his Sonic Heroes appearance. Surprisingly, it's just Ryan Drummond's Sonic voice in monotone, with the pitch deepened and with a synthesized reverberation added. Hear it unaltered.
  • Failure Is the Only Option: No matter how hard he tries, he can never defeat Sonic. Hell, in the Sonic the Hedgehog/Mega Man: Worlds Collide comic series, Sonic even lampshades it by listing his previous defeats to rub salt in the wound.
    Sonic: Give it up, man! I've beaten you in every race, every fight, and even that time you turned into that stupid dragon thing!
  • Family-Unfriendly Death: In the Movie, he basically commits suicide by allowing himself to be baked in the lava.
  • Finger Firearms: He can fire his claws like missiles as Metal Madness. If it hits a character, he or she is trapped in a cyrstal dome. If all three characters are trapped, they lose a life.
  • Flight: Thanks to a jet engine on his back.
    • Flying Brick: Especially in the Movie. His main fighting style is to fly into things at top speeds, usually when performing the V. Maximum Overdrive Attack.
  • Fire-Breathing Weapon: Metal Madness's right hand is a flamethrower that he uses against Team Rose and Team Dark.
  • Fragile Speedster/Glass Cannon: He was designed to be faster and stronger than Sonic, both of which he gets down, but he's prone to overheating after attacking and can be neutralized by flying into a wall.
  • Good Wings, Evil Wings: Metal Overlord has some sharp and scary-looking wings.
  • The Heavy: If he didn't challenge Team Sonic while impersonating Eggman, Sonic Heroes wouldn't even exist.
  • Heroic Sacrifice: In the Archie Comics, Metal sacrificed himself to save Sonic and Tails by stopping a lava flow, and was eventually engulfed by it.
  • High-Altitude Battle: The fight with Metal Overlord in Heroes.
  • I Have Many Names: Metal Sonic, Mecha Sonic, Metallix...
    • Though Mecha Sonic (at least in the games) is a separate character.
    • In the Movie, he was called Hyper Metal Sonic.
  • Humongous Mecha: His Metal Madness and Metal Overlord forms.
  • I Just Want to Be You: Implied to be his beef with Sonic, although it overlaps heavily with There Can Only Be One, as Metal's goal of defeating Sonic and proving his own self-worth is his sole purpose for existing.
  • Image Song: Metal Sonic has many themes, which fit him extremely well:
  • Inferiority Superiority Complex: Heavily implied to have this. He was created with the sole purpose of defeating Sonic, but no matter how hard he tried, he could never pull it off, even when he found that Amplifier Artifact in Sonic 4. By Sonic Heroes, his inferiority complex and obsession with defeating Sonic had grown so out of control that it drove him completely insane and caused him to copy the powers of Sonic and his friends and attempt to Take Over the World just to prove he's better than Sonic.
  • Japanese Pronouns: "Ore."
  • The Juggernaut: Metal Overlord. It's saying something that it took 12 characters to put him down. Nine of them had to distract him so Team Sonic could use their super powers. Then the three of them had to finish him off.
    • In his debut appearance in Sonic CD, Sonic can't even harm him due to his electrified force field, and Metal can effortlessly smash through obstacles that Sonic has to work around. Sonic has to rely on a combo of the raceways closing gate and Eggman's instant kill laser to bring him down.
  • Kick the Dog: Your first clue that he's bad news is a hologram recording in Palmtree Panic of Metal Sonic stepping on a squirrel for no reason.
  • Killer Robot
  • Knight of Cerebus: For Sonic Heroes, but nowhere near the level of the Black Arms and Mephiles the Dark, mainly because, despite his obvious new powers, he's more talk than show in battle due to his overinflated ego, and his motives are entirely centered on a petty goal of getting revenge on Sonic by any means.
    • He's also this in the Movie. The movie starts off pretty lighthearted for the most part. There's copious amounts of humor due to Sonic's snark and Old Man Owl's ditzyness. Robotnik himself barely registers as a threat due to his Affably Evil, Go-Karting with Bowser nature. But once Metal Sonic appears, the movie quickly goes from funny to frightening as we get a villain with no comedic traits and is genuinely threatening.
  • Large Ham: He chews the scenery with almost every one of his lines in Heroes, including the portions where he was disguised as Eggman. "All living things, KNEEL BEFORE YOUR MASTER!"
  • Leitmotif: Tends to have the Bad Future Stardust Speedway tracks play in his fights.
  • Macross Missile Massacre: Metal Madness and Metal Overlord can fire missiles from the spikes on his back.
  • Noble Demon: Toward the end of the Movie, thanks to his programming being based on the real Sonic's mind.
  • No Mouth: In his normal and Neo forms, although he was often drawn with a crude pasted on smirk on his muzzle in artwork for the Genesis Sonic games. Subverted with his Metal Madness and Metal Overlord forms.
  • Omnicidal Maniac: Implied, but not outright stated. During the Final Battle with him in Sonic Heroes, he mentions wanting to rule a robot kingdom, slightly implying he wanted to destroy all organic life.
  • One-Winged Angel: Metal Overlord in Sonic Heroes, and even earlier he did this to become Mega Metal Sonic in Knuckles Chaotix.
  • Our Dragons Are Different: Metal Madness and Metal Overlord resemble western dragons.
  • Out of Focus: Nowadays, Metal mainly makes cameo, playable, and boss appearances.
  • Over Drive: The V. Maximum Overdrive Attack, as its name would suggest, is stated to be rather taxing on Metal's systems - enough so that sustained use could potentially destroy him.
  • Person of Mass Destruction: He's this in the movie, and in his Neo Metal Sonic and Metal Overlord forms.
  • Pet the Dog: In the Movie, After defeating Sonic the first time, He tracks down Old Man Owl... to give him Sonic's favorite clothes.
  • Power Copying: His main superpower, used to copy the abilities of everyone in Sonic Heroes. And he does it again in Sonic Free Riders, Diguising himself as a blue E-100000 to copy everyone's Extreme Gear data.
  • Rage Quit/Sore Loser: In Sonic Free Riders. After challenging Sonic to a race and, predictably, losing spectacularly, Metal runs off in a rage.
  • Ramming Always Works: His V. Max Overdrive attack, where he overclocks his systems to make himself hazardous to touch and zoom across the stage.
  • Red Eyes, Take Warning
  • Redemption Equals Death: In the Movie, Metal Sonic saves the President and Old Man Owl from an exploding hovercraft, only to be smashed into a lava pool he had opened up a few minutes ago.
  • The Resenter: To Sonic.
  • Robot Me
  • Robotic Psychopath
  • Sanity Slippage: Shown in Sonic Heroes He was created for the sole purpose of defeating Sonic, but each defeat caused his hate and resentment towards Sonic to build until it reached critical mass. It eventually all goes to hell, driving him mad with power and ego and causing himself to believe that he was the real Sonic.
  • Second Law My Ass: Pulled this one out in Sonic Heroes; Fed up with Dr. Eggman's failures, he threw the doctor into a room and took over the Eggman Empire himself to go about his own plans.
  • Shock and Awe: Most of his attacks, such as the V. Max Overdrive Attack and the Ring Spark Field deal with electricity. Neo Metal Sonic can fire lightning from his hands, and as shown in Sonic the Hedgehog 4, he's still capable of this to some degree.
  • Smug Snake: He may not be the real Sonic like he claims to be, but at least he's got all of Sonic's ego.
  • Some Kind of Force Field: Besides the Black Shield ability from Sonic Adventure 2 Battle, he also projects one in Sonic the Hedgehog: The Movie whenever he's flying around, especially when he piledrives into Planet Freedom from space.
  • Spikes of Villainy: Neo Metal Sonic wears a spiked belt. His Metal Overlord form has spikes on his back. And they aren't just for show.
  • The Starscream: In Sonic Heroes, although by his defeat, Eggman reprogrammed him to ensure this would never happen again — although that may not have been foolproof, since Sonic Free Riders shows he still has hints of free will, going behind Eggman's back to copy the racers' data, and promptly challenge Sonic to a new race.
  • Super Speed: Naturally. He is a robot of Sonic after all.
  • Talking to Himself: He and Sonic were voiced by the same American and Japanese actors in Heroes.
  • There Can Only Be One: There is only one Sonic.
  • The Only One Allowed to Defeat You: To Sonic. He takes it Up to Eleven in Sonic Heroes, where he's not only obsessed with defeating Sonic, but believes that he is the real Sonic.
  • This Was His True Form: While he didn't actually die in Heroes, after he's defeated he shrinks from his Neo Metal Sonic form into the Sonic CD appearance we're all more familiar with.
  • Villainous Breakdown: When defeated in Sonic Heroes.
    Metal Overlord: "Guooooo! Why?! I had it all! I am the ultimate overlord, Metal Sonic. I am the real Sonic!"
  • Villain Protagonist: In Episode Metal.
  • The Voiceless: In all appearances barring Heroes (where he's Suddenly Voiced after receiving an upgrade) and The Movie (where he's The Quiet One, and has exactly one line of spoken dialogue).
  • Voluntary Shapeshifting: He gained this ability circa Sonic Heroes, at least the ability to superficially imitate them in appearance. He gets the ability to outright morph, T-1000 style by copying Chocola Chao and Froggy's data (who had the DNA of Chaos in them), and Sonic Free Riders shows that he can still pull this off to some degree.
  • Walking Spoiler: For a while, in the wake of his role in Heroes, Metal served as this, although it's greatly diminished over time.
  • We Can Rebuild Him: Claims to have done this to himself before the events of Heroes to defeat Sonic.
  • With Great Power Comes Great Insanity: Read the above.
  • Xanatos Gambit: His Batman Gambit to Team Sonic can be seen as this. If Team Sonic answers his challenge, he can copy their data, if they don't, he can conquer the world with his Egg Fleet. Either way, he wins.
  • X-Ray Sparks: In Sonic & All-Stars Racing Transformed, he shows a skeleton when electrified.

    Orbot and Cubot 
Orbot on the right, Cubot on the left

Orbot's Debut: Sonic Unleashed
Cubot's Debut: Sonic Colors

Orbot: Voiced by Mitsuo Iwata (Japanese), Chris Collet (English, 2008), Kirk Thornton (English, 2010-present)
Cubot: Voiced by Wataru Takagi (Japanese), Wally Wingert (English)

Dr. Eggman's robotic assistants.

  • Affably Evil: Working for Eggman is really the only reason they can be considered evil. In Sonic Lost World, Orbot even asks Sonic if he can became his new sidekick, thinking it would better to work for him than Eggman.
  • Art Evolution: In Sonic Unleashed, Orbot had a white casing. Sonic Colors onwards, his casing was red to better contrast the yellow Cubot.
  • Canon Immigrant: The concept of robot buddies to work off a somewhat comically inept Eggman likely comes from at least two adaptations.
  • Characterization Marches On: Orbot was very disrespectful to his master in Sonic Unleashed, snarking on his inability to do things right, even having a different color. In Sonic Colors, he's much more like a butler with much more subtle sarcasm, some guess that it may be due to having a new voice chip, or being a new Orbot altogether. In Sonic Lost World, he returns somewhat to his original snarky self, asking Sonic if he can leave Eggman to be his new sidekick, within earshot of Eggman.
  • Cloudcuckoolander: Cubot. Though his faulty voice chip doesn't help.
  • Cloudcuckoolander's Minder: Orbot.
  • Co-Dragons: In recent games, the two have been Eggman's main, though ineffectual, backup. They're demoted to Dark Chick status when Metal Sonic shows up however.
  • Dark Chicks: They have no combat experience to speak of, and are by far the quirkiest of Eggman's minions.
  • Deadpan Snarker: Orbot.
  • The Ditz: Cubot.
  • Fan Nickname: "Ergo" for Orbot, due to his constant use of the word in Unleashed.
  • Mecha-Mooks
  • Harmless Villains
  • Motor Mouth: Cubot, especially when he gets his old voice back.
  • Losing Your Head: Cubot is decapitated when the Deadly Six turn on Eggman. Being a robot, he survives.
  • Odd Friendship
  • Plot Armor: In Sonic Lost World The two seemed to be immune to the Deadly Six's ablility to manipulate electromagnetic fields. Though it's possible that the Six either can't control sentient robots or just didn't bother to control them due to their ineffectiveness in combat (and everything else).
  • Plucky Comic Relief
  • Portmanteau: "Orbot" is one of "orb" and "robot", while "Cubot" is "cube" and "robot".
  • Production Nickname: Orbot's was SA-55, a Letters 2 Numbers rendition of "sass". Likewise, Cubot's was shown in comics to be IDI-07, "idiot".
  • Remember The New Guys: Both of the robots started appearing without any fanfare, as if they've been around to witness Dr. Eggman's failures for a while.
  • Sarcastic Devotee: Orbot.
  • Servile Snarker: Orbot in spades.
  • Sleep Mode Size: When not in use, they compress themselves into a sphere and a cube, respectively.
  • Snarky Non-Human Sidekick: Orbot.
  • Something We Forgot: A recurring side-plot in Colors is Orbot and Cubot trying to find the latter's original voice chip, because every substitute chip used changes his voice and personality to be gradually worse. Near the end of the game, Cubot finally restores his old voice, and... well...
    Eggman: "Now I remember why we changed his voice chip."
  • Terrible Trio: Forms one with Eggman.
  • Those Two Bad Guys
  • Unexplained Recovery: As seen in Sonic Generations, Eggman left them in space. Despite this, they reappear in Sonic Lost World.
  • Voice for the Voiceless: Metal Sonic can't talk, so in Mario & Sonic at the London 2012 Olympic Games's London Party mode, they talk for him.
  • Yes-Man: Despite Orbot's snarky attitude, he's always willing to follow Eggman's orders.


Secondary Antagonists

    Fang The Sniper A.K.A Nack The Weasel 
Debut: Sonic Triple Trouble

Debuted as "Fang the Sniper" in Japan and "Nack the Weasel" in North America and Europe (although this decision was soon revoked in subsequent appearances). He's a treasure hunter out for cash whose only main appearance was in Sonic Triple Trouble. He also showed up in a few spinoffs, but that's it.

    Pachacamac 

The leader of the Knuckles Tribe and father of Tikal, he made Chaos angry. Sole appearance in the games is Sonic Adventure, where his actions are revealed to be the mainspring of the games conflict.

    Prof. Gerald Robotnik 
"All of you ungrateful humans, who took everything away from me, will feel my loss, and despair!"

Debut: Sonic Adventure 2

Shadow's creator and Eggman and Maria's late grandfather. 50 Years before the events of Sonic Adventure 2, his granddaughter was diagnosed with a terminal illness. Gerald desperately tried to find a cure, which prompted the start of Project: Shadow and his research into immortality. The government however got suspicious of Gerald's motivations and ordered the project to be shutdown, with Maria being among those who died in the raid. Gerald snapped and swore revenge on humanity, and his plan would come to fruition for those who sought to unleashed Shadow.

  • Bigger Bad: Everything in Sonic Adventure 2 that happens is because of this guy, even he's been dead for 50 years.
  • Broken Pedestal: Dr. Ivo Robotnik idolized Gerald... after the events of Sonic Adventure 2... not so much.
  • Colony Drop: This is his way to gain revenge on humanity, by destroying the Earth with the ARK.
  • Deal with the Devil: He needed a sample of Black Doom's DNA to complete Shadow, and in exchange, Shadow would help Black Doom take over the planet 50 years later. Gerald had other plans fortunately.
  • Despair Event Horizon: Once Gerald was a highly respected scientist who wanted to help people through science. After his granddaughter Maria's death at GUN's hands, he quickly started becoming evil and ended up a wannabe Omnicidal Maniac as his Final Speech shows.
  • Dying Declaration Of Hate / Final Speech: Gerald's speech to the firing squad set to execute him which outlines his Colony Drop to all of humanity is basically his Disproportionate Retribution.
  • Humans Are Bastards: Developed this mentality after Maria died.
  • Killed Off for Real: Executed by a firing squad.
  • Mad Scientist: Gerald, unlike his grandson, Dr. Ivo Robotnik, was not this and used his inventions to help humanity. Even the Eclipse Cannon was to be used to stop Black Doom as revealed in Shadow the Hedgehog. Then Maria died, and then he definitely became a Mad Scientist.
    • His experiments and deal with Black Doom, allowed him to create both Shadow the Hedgehog and his prototype, the Biolizard.
  • Misanthrope Supreme: Instantly became one after GUN killed Maria.
  • Misplaced Retribution: Wanting to destroy all humanity when only GUN was responsible for his granddaughter's death.
  • Omnicidal Maniac: But only after Maria's death, and the related plan happens far after his death.
  • Posthumous Character: However, his plan to destroy the Earth by crashing the ARK into it keeps going on even fifty years after his death.
  • Sanity Slippage: As noted by himself, Maria's death pretty much broke whatever sanity he had left.
  • Strong Family Resemblance: Especially in Shadow the Hedgehog, where's fatter and basically looks just like Eggman, except with a neater mustache and a labcoat. Also applies to their descendant, Eggman Nega. Averted with Maria though.
  • Supervillain Lair: Used the ARK, a giant space station he created, for making experiments to destroy the world after becoming evil.
  • Tragic Villain: Originally a scientist who wanted to work for the benefit of humanity and cure his ailing granddaughter, but delved into a vengeful old man who cursed the world.
  • Woobie, Destroyer of Worlds: He hates humanity with all his heart, but only because they took his granddaughter from him.

    Black Doom 
"I gave you life, and this is how you repay me? The irony of it is, I gave you life. And now, I'll take it back."

Voiced by Ryuzaburo Otomo (Japanese), Sean Schemmel (English)

An alien being from the Black Comet who helped create Shadow and tries to enlist his help in conquering the Earth.

    Mephiles the Dark & Iblis 
The two components that make up the being known as Solaris, Mephiles represents it's intelligence and Iblis, it's raw power. Sometime before the events of Sonic the Hedgehog (2006), Solaris was experimented on by the Duke of Soleanna, but an accident separated the entity into its two components. Mephiles was sealed in the Scepter of Darkness by Shadow, and Iblis was sealed by Silver in the young Princess Elise.

Tropes Applying to Both


  • Big Bad Duumvirate: One of the three primary threats of Sonic the Hedgehog (2006). It's more on Mephiles' side, though, since Iblis has no intelligence to speak of.
  • Eldritch Abomination: Continuing the trend of Lovecraftian enemies within the series.
  • Fusion Dance: The two of them can combine to regain their original form, Solaris.
  • Red Oni, Blue Oni: Iblis simply destroys everything in it's wake with no rhyme or reason and it's primary color is red. Mephiles, while possessing formidable abilities himself, is more the manipulative one of the two.


Mephiles the Dark

"Why fight at all? Why risk your life for those who will persecute you later?"

Voiced by Takayuki Sakazume (Japanese), Dan Green (English)
  • Arch-Enemy: Despite the fact that he's only in one game, he was a pretty personal foe to Shadow moreso than any other character in the game.
  • Attack Its Weak Point: As Solaris, the hedgehogs must hit the red orb to damage him.
  • Ax-Crazy: Let's see, his plans essentially amount to the destruction of existence in itself, his hatred of Shadow is almost to the point of psychosis, and he also laughs exhileratedly at Sonic's (supposed) death? Seems to fit that to a T.
  • Badass: Ridiculously complex scheming aside, this guy managed to succeed in his plan to destroy the timestream, and is the first and so far only villain in the series to actually kill Sonic!
  • The Bad Guy Wins: He actually succeeds in his plan to destroy the planet, and also heavily damaged the time-space continnum, and it is even implied that the time-space continuum was also rapidly dying throughout the final story. The Final Story is basically the heroes trying to set things right.
  • Big Bad: Of Sonic 2006.
  • Casting a Shadow: He can meld into a Living Shadow, bring shadows to life and merge them together to form larger shadow monsters, hide in the shadows of others, absorb shadows to grow stronger, and fire dark energy blasts.
  • Colour Coded Characters: The main difference between him and Shadow; initially, Mephiles's stripes are a gray-blue instead of Shadow's red.
  • Complexity Addiction: His plans could be... a bit simpler.
  • Dangerously Genre Savvy: He manipulated Silver's desire to fix his timeline into trying to kill Sonic and anticipated the likelihood that Silver will end up not going through with it, so he recovered one of the Chaos Emeralds and proceeded to use it to distract Sonic and Elise while he inflicts the coup de grace. Even afterwards, as Solaris, he had several rifts scattered throughout what's left of the world in order to stop the heroes from recovering the Chaos Emeralds and reviving Sonic.
  • Dark Is Evil: Just look at his name; Mephiles the Dark.
  • Dirty Coward: He fights usually when the opponent isn't looking, he even murdered Sonic while his back was turned.
    • A dose of Fridge Brilliance, considering he was the mind and will of Solaris while Iblis, his counterpart, was the raw power. It'd stand to reason he's not powerful enough to take anyone on in a head-on fight without some additional support. In other words, he knows his limitations.
  • Eldritch Abomination: His true form is a transcendent time entity capable of devouring entire dimensions.
  • Evil Laugh: lets out a good one when he kills Sonic.
  • Evil Twin: To Shadow.
  • Expy: Of Agent Smith.
    • To a lesser extent, he also acts as the Sonic equivalent of Kefka Palazzo, due to their initially succeeding in their overall plans of destroying the world, frequently doing destructive acts for no stated reason besides For the Evulz at best, and their defeats resulting in at the very least a Bittersweet Ending and at worst a Pyrrhic Victory in their respective games.
  • For the Evulz: The only suggestible reason that he wants to completely destroy space and time. Beyond being pissed at some scientists experimenting on him.
  • Fragile Speedster: Played with: He's very intelligent, capable of teleportation, time travel, and energy manipulation. However, he has noticable trouble taking physical punishment while fighting Shadow, although he was shown taking on and withstanding several shotgun/minigun blows from Omega when confronting him in a cutscene.
  • Frickin' Laser Beams: His main attack as Solaris. Gets taken Up to Eleven when he Turns Red.
  • God of Evil: Solaris.
    • Mad God: Again, Solaris, although it's "mad" as in "rage" and not "mad" as in "insanity."
  • Hellish Pupils
  • Killed Off for Real: Heavily implied by the ending of the game (via Grandfather Paradox).
  • Knight of Cerebus: Prior villains were either somewhat comical, or had some justifications behind their motives. Mephiles possessed none of these, and clearly enjoys causing destruction simply because he could, and was also the first major villain to canonically kill a major character (and in fact also killed Sonic), as well as succeeding in destroying the world as well as the fabric of existence, with the final act being to stop Mephiles' Fusion Dance god form and restore the timeline.
  • Know When to Fold 'Em: The implied reason why he often pulls dirty tactics on his opponents.
  • Lack of Empathy: He taunts Omega about his part in sealing away Shadow in the future, and he laughs after (supposedly) murdering Sonic, and especially at Elise's sorrow and mental anguish at his (Supposed) death.
  • Large Ham: Probably the other reason a lot of people like him, what with being voiced by Dan Green and all...
  • Laughing Mad: He laughs quite exhileratedly when murdering Sonic.
  • Light Is Not Good: Solaris again.
  • Literal Split Personality: Both Mephiles and Iblis. Mephiles being the conscious mind, and Iblis being the raw power.
  • Living Shadow: Not only is he the Shadow Archetype to Shadow, but he's also born (well, reborn is more accurate) from Shadow's shadow. That's right, Shadow's shadow became a Shadow.
  • Manipulative Bastard: This along with The Chessmaster. He manipulated seemingly everyone in the story over 210 years just so he could force Elise to develop feelings towards Sonic, only to kill Sonic, thus freeing Iblis from inside Elise, allowing himself to merge with Iblis to become Solaris. Even more impressive is that he doesn't actually lie to Silver at all. He just leaves out a TEEEENY by important piece of information.
  • Names to Run Away From Really Fast: Overlaps with Meaningful Name. Mephiles = Mephistopheles, the demon from Faust, sometimes associated with Satan. Likewise, Iblis is the Islamic name for the Devil before his fall. See below in the Iblis section for more.
  • No Mouth: His muzzle kind of inflates and deflates when he talks, though.
  • Not So Different: He is in a way a darker version of Shadow's Sonic Adventure 2 personality. Both are chessmasters that played the desires of another to follow suit to their plans (Shadow to Eggman, Mephiles to Silver). Both desired revenge on humanity (especially those that experimented on them), though for Mephiles revenge was only a side-motive. And both nearly succeeded. Shadow's plan only failed because he decided he didn't want to go through with it. Mephiles' plan actually WORKED and the heroes had to really struggle to undo it.
    • Another example would be their planet sized egos.
  • Obviously Evil: And yet, the plot hands out a 10-ton Idiot Ball to Silver and Blaze, as they believe him.
    • They live in a post-apocalyptic world, and are among the few people left alive. It's doubtful they're familiar to this trope.
    • He's the mind of Solaris given a physical form. The demonic appearance represents how angered and psychotic Mephiles/Solaris is.
  • Omnicidal Maniac: He wants to destroy all time and every timeline. Why? Never explained.
    • It's heavily implied that his reason is because he loves destruction. Craves it, in fact.
    • Plus you'd be pretty pissed too if some scientists decide to drag you out of your reality and experiment on you.
  • One-Winged Angel; Aside from his true form as Solaris, before fighting Shadow, he transforms into a chrystalline version of himself as pictured above.
  • Our Demons Are Different
  • Physical God: If it wasn't obvious.
  • Red Eyes, Take Warning: An inversion. His irises are normally green, while in his One-Winged Angel form, the sclera (the white part of the eye) turns completely red.
  • Ret Gone: Thanks to Elise blowing out the flame that is Solaris, Mephiles is erased from existence.
  • Satanic Archetype: He's practically the Sonic universe's equivalent of this. See above.
  • Sealed Evil in a Can: Shadow sealed him in the Scepter of Darkness.
  • Smug Snake: He's both manipulative and a big planner, but his lack of common sense makes him this.
  • The Sociopath: The universe is just a stress toy to him. And he'll play with it until it breaks.
  • Spacetime Eater: As Solaris.
  • Story-Breaker Power: He can Time Travel to any point in time at will, can transport anyone through any point in time, and can apparently summon all seven Chaos Emeralds to his side. It's a wonder as to why the plot doesn't end in seconds because of this.
  • Straw Nihilist: He asks Shadow why he continues to fight and attempt to protect humanity when they'll only persecute him later on.
  • Time Travel: Seems to be one of his main abilities. He can banish others to other time periods as well.
  • Turns Red: During the fight as Solaris, He attacks more frequently and increases the number of laser beams he fires.
  • The Voiceless: Doesn't say a word as Solaris.
  • Villains Never Lie: Technically, he wasn't actually lying when he told Silver that Sonic was the Iblis Trigger. All he does is omit the fact that KILLING sonic is what makes him the Iblis Trigger

Iblis

A lava monster that devastated the entire world in the future where Silver and Blaze come from. He is the other half of the god of time and light, Solaris.

    Erazor Djinn 

Voiced by Masashi Ebara (Japanese), Peter Cormican (English)

The evil genie of the lamp who wants to erase the Arabian Nights.

  • Ain't Too Proud to Beg: He's reduced to begging Shahra to help him when he's being forcibly sealed into his lamp.
  • A God Am I: In his One-Winged Angel mode.
  • And I Must Scream: before his death in the lava.
  • Badass Cape: He takes it off when he fights Sonic.
  • Big Bad: Of Sonic and the Secret Rings
  • Beware My Stinger Tail: As Alf-Wayla-La-Walya, his sword has now become his tail.
  • Black Eyes of Evil/Red Eyes, Take Warning
  • Body Horror: His transformation was both unsettling and painful to say the least.
  • Clipped Wing Angel: His transformation is actually incomplete. Because he got the wrong sacrifice, he wasn't able to absorb all seven World Rings.
  • Cool Sword: One that resembles a cross between a scimitar and a straight-edge razor.
  • Death by Irony: Used a Flame of Judgement curse on Sonic to force him to retreive the Sacred Rings. Guess how he dies?
  • Domestic Abuser: Heavily mplied to be this to Shahra. His We Can Rule Together offer to her sounds like something an abusive boyfriend would say and his Villainous Breakdown sounds like an abusive boyfriend trying to get his girlfriend back on his side.
  • Duel Boss: Despite being an all-powerful genie who's power is described by King Solomon as "godlike", when it's time for the final battle with Sonic, he doesn't fight him with anything but his sword.
  • Evil Is Hammy: Oh boy, is it ever.
  • Elderitch Abomination: In his true form.
  • Expy/Shout-Out: An evil Djinn that seeks to conquer the world? He'd fit right in in the Wishmaster series. He also looks a lot like Dragon Ball's Majin Buu.
  • Family-Unfriendly Death: Baked in lava.
  • Humiliation Conga: Hoo boy! It wasn't enough that he had to get his ass kicked by Sonic. Oh no, he had to suffer. To elaborate, Just as he's boasting to Sonic that he's immortal, Sonic pulls out the lamp used to seal him away. Sonic then uses the lamp to painfully force Erazor to grant him three wishes: That he revives Shahra, return the Arabian Nights to the way they were, and be sealed in the lamp for eternity. The mighty genie is reduced to shamelessly begging Shahra, a weak genie of the ring, for help as he's sealed away. The final nail in his coffin is when Sonic throws the lamp into the Ifrit's lava pool, destroying Djinn forever.
  • Kick the Dog: Mocks Shahra as a mere Genie of the Ring after killing her.
  • Lack of Empathy: Feels no regret when he accidently kills Shahra, and even has the gall to mock her.
  • Manipulative Bastard: He is to Shahra.
  • Meaningful Name: Both. Erazor Djinn is a mix of 'Eraser' and 'Razor', as to how he's tearing apart the Arabian Nights and he uses a straight razor as a sword. And again as Alf-Layla-wa-Layla, which translates as 'A thousand nights and one night'. He's calling himself The Arabian Nights. Also doubles as a Bilingual Bonus.
  • Multi-Armed and Dangerous: Has six arms as Alf-Layla-wa-Layla.
  • One-Winged Angel: Alf-Layla-wa-Layla
  • Orcus on His Throne: Spends his time at his Night Palace while Sonic's out collecting rings. He later summons the Ifrit demon to burn the remaning pages of the book.
  • Playing with Fire: Ironic, considering his death.
  • Power Floats: Is never seen walking.
  • Real Men Wear Pink: Has pink skin.
  • Sadistic Choice: Gives one to Sonic at the outset of the game via the flame of judgement curse: Either Sonic delivers the Seven World Rings to him, or the flame will kill him. Then it's subverted when he reveals that he was planning on sacrificing Sonic to obtain complete control of the rings.
  • Sealed Evil in a Can: Prior to the game, he was imprisoned in his lamp and would not be released until he granted the wishes of 1000 people. He gets sealed back in the lamp at the end of the game.
  • The Sociopath
  • Villainous Breakdown: When Sonic reseals him back into his lamp.
    Erazor: Shahra, I know you're there! Please, stop him! We can start over, the two of us! I swear! I swear it! The world is mine! I cannot be denied by that filthy rat! Whyyyyy?!
  • Walking Shirtless Scene
  • We Can Rule Together: Offers this to Shahra.

    Dr. Eggman Nega 
"Now, the world shall be my plaything! I shall bring about an age of fear and chaos! And it shall be glorious!"

Debut: Sonic Rush

Voiced by Chikao Ohtsuka (Japanese), Mike Pollock (English)

Dr. Eggman's descendant from the far-flung future where Silver is from.

  • Alternate Self: He's initially introduced as one of Eggman, though it laters turns out that he's actually his descendant from the future.
  • Ain't Too Proud to Beg: In Espio and Sliver's story in Sonic Rivals 2, his legs are caught in debris following the Ifrit's defeat and he's forced to beg them for help. It doesn't work and they leave him in the Ifrit's dimension.
  • And I Must Scream: The Sonic Rivals series has him on both ends of the trope. In the first game, he uses a special camera to turn people into cards and planned to do this to the entire world. He gets sealed in a card himself by the end of the first game, but he breaks out of the card by the second game only to get trapped in the Ifrit's dimension at the end.
  • Arch-Enemy: To Blaze and later Silver.
  • Ax-Crazy: Unlike Eggman, who wants to leave the world intact and take it over, Nega gets a kick out of wanton destruction.
  • Badass Bookworm: Much like Eggman.
  • Badass Moustache: Like Eggman, he has this.
  • Bald of Evil
  • Big Bad: Of the Sonic Rivals games.
  • Camera Fiend: A dark twist on the trope. In the first Rivals game, he uses a special camera that turns anything or anyone into a card.
  • Cool Shades: Even cooler than Eggman's pince-nez, Eggman Nega sports a Kamina-esque visor.
  • Calling Your Ancestor Out: Eggman Nega's primary motivation in Sonic Rivals is revenge against Dr. Eggman (who is his ancestor) because Eggman's various failures made him be looked down upon despite having high potential in terms of intellect.
  • Eviler Counterpart: To Dr. Eggman; he completely lacks any redeeming aspects Eggman possesses.
  • Evil Genius: And even has the benefit of 200 years of technological advancement over Eggman.
  • Evil Old Folks: Probably. He has a gray moustache.
  • Eviler Twin: Of Eggman, at least in the Rush series. The Rivals series reveals that he is actually Eggman's descendant.
  • Fat Bastard: And even more of a bastard than Eggman.
  • Freudian Excuse: In Rivals he was mistreated because of his ancestor's many failures.
  • Faux Affably Evil: A reverse of the Affably Evil Eggman, Eggman Nega appears to be pleasant and well-mannered, but is a raving psychopath under the veneer of sophistication and class.
  • For the Evulz: He does have a plan, but it's not hard to see that he enjoys the chaos he causes.
  • Four Eyes, Zero Soul
  • Hoist by His Own Petard: In Sonic Rivals, he's trapped in a card himself due to an accident with the camera. In Sonic Rivals 2, he unleashed the Ifrit and, following its defeat, was sealed in the Ifrit's dimension.
  • Identical Grandson: He is physically identical to Eggman, sans the white mustache. And in the Rivals series, he exploits this by diguising as him.
  • Japanese Pronouns: "Watashi".
  • Kid from the Future: He is Eggman's descendant from approximately 200 years into the future.
  • Knight of Cerebus: In contrast to Eggman, anything involving Nega is treated far more seriously.
  • Mad Scientist: Even more mad than Eggman is.
  • Make Wrong What Once Went Right: Eggman Nega's motivation in the first Sonic Rivals game, which is only revealed in Shadow's playthrough, is to erase the "failures" of Dr. Eggman, because Nega apparently didn't have anyone recognize his genius because of Eggman's failures.
  • The Man Behind the Man: He and Eggman pull this off in Sonic Rush Adventure, being the ones who created Captain Whisker to steal the Jeweled Scepter.
  • Manipulative Bastard: To Rouge in Sonic Rivals 2, hiring her to collect the Chaos Emeralds.
  • Mask of Sanity: He puts up a polite, gentlemanly facade, but underneath it, he's a complete psychopath who, unlike Eggman, has no redeeming qualities.
  • Multiple-Choice Past: In the Rush series, he is from another dimension, in others (notably the Rivals series) he is from the future. The different writers work around each other by making sure that no one heroic character hears both stories.
  • Never My Fault: Shadow accuses him of having this mindset, stating that his motive is merely an excuse to blame his own failures on the past.
  • Omnicidal Maniac: In both the Rush and Rivals series, he wants to destroy the entire world somehow.
  • Palette Swap: Of Eggman. It made sense when he was supposed to be Eggman's dimensional counterpart, but his official backstory is that he's a descendant of Eggman.
  • Psychopathic Man Child: And he leans more on the "psychopathic" part.
  • Sarcastic Clapping: How he introduces himself in Sonic Rush Adventure.
  • Strong Family Resemblance: To Eggman and Gerald, his ancestors.
  • The Sociopath
  • Sore Loser: Unlike Eggman, who takes his defeats gracefully in comparison, if Eggman Nega does down, he tries to take the entire world with him.
  • To Create A Playground For Evil: His motivation, shown in the quote above.
  • Villainous Breakdown: At the End of Sonic Rush Adventure, he activates the Egg Wizard's Planet Buster Laser in a final attempt to defeat Blaze and Sonic, much to the dismay of Eggman.
  • Villains Want Mercy: See Ain't Too Proud to Beg.
  • Vocal Evolution: Originally, he used the same voice clips as Eggman. As of Rivals 2, Mike Pollock gives him a more distinctive, higher pitched voice than Eggman.
  • White Mustache Black Heart

    Captain Whisker 

A robot pirate from the Sol Dimension.

    Imperator Ix 

The leader of the Nocturnus Clan and the final boss of Sonic Chronicles.

    Dark Gaia 

Born at the beginning of time, Dark Gaia is the incarnation of night, darkness and destruction. Sealed within the Earth for millions of years, he was woken up by Dr. Eggman as part of a scheme to dominate the world.

    Time Eater 

An Eldritch Abomination capable of destroying time and space, as well as altering time and space in various ways. Time Eater starts destroying history and petrifies Sonic's friends during Sonic's birthday, making Sonic team up with his past self to stop the Time Eater in Sonic Generations.

Time Eater is technically an Eldritch Abomination, but also a Humongous Mecha, transformed into such by the Villain Team-Up of Doctor Eggman and his past self. Both Eggmen control the Time Eater to erase their previous defeats at Sonic's hands.

    Deadly Six 
Clockwise from the middle: Zavok, Zomom, Zik, Zeena, Zor, and Zazz
Voiced by; Joji Nakata (Japanese) Travis Willingham (English) (Zavok), Chafurin (Japanese) Patrick Seitz (English) (Zomom), Mugihito (Japanese) Kirk Thornton (English) (Zik), Yumi Touma (Japanese) Stephanie Sheh (English) (Zeena), Yuki Tai (Japanese) Sam Riegel (English) (Zor), Yutaka Aoyama (Japanese) Liam O Brien (English) (Zazz)

Zavok: "Your fate is to be destroyed. Why don't you just accept that? Lie down and die!"
Zazz: "You wouldn't like me when I'm angry!!!"
Zeena: "I'll say you got the right girl for the job."
Zomom: "I think I'll have you for dessert!"
Master Zik: "I shall prepare for you a lesson in respect... a painful lesson."
Zor: "Another pointless conflict is about to begin... Sigh..."

The villainous team in Sonic Lost World. They are Zeti, a race of creatures who reside on the Lost Hex, where the game takes place. After Eggman tries to control them to take over the world, they rebel and decide to take over it themselves. They are composed of Zavok (Red), Zazz (Pink), Zeena (Green), (Master) Zik (Blue), Zomom (Orange), and Zor (Purple).

  • Abnormal Ammo: Zik uses fruit as attacks in his boss fight.
  • Abusive Parents: Zomom appparently had a mother with zero faith in him:
    Zomom: Mom's right - I'm a failure!
  • Accessory Wearing Cartoon Aliens
  • Achilles' Heel: The Cacophonic Conch, which emits a Brown Note that neutralizes their electromagnetic powers and debilitates them. So it really sucks for everyone when Sonic kicks the conch away, letting them run amok uninhibited.
  • Acrofatic: Zomom is quite agile for such a big guy.
  • Actor Allusion: This isn't the first time Travis Willingham voiced a character who uses his guile to coerce a female ally.
  • Advancing Boss of Doom: Zavok's final battle with Sonic has him growing to giant size and chasing the blue hedgehog as he climbs a tower.
  • Affably Evil: If they weren't trying to destroy the world, you'd think these guys were just a crazy, Ragtag Bunch of Misfits. Though Zavok and Zazz tend to border on Faux Affably Evil.
  • Aliens Are Bastards
  • Alpha Bitch: Zeena.
  • An Ice Person: Zeena attacks with snowmen and a giant snowman head during her fights, though whether she actually has ice powers or is just being an Improbable Weapon User is rather ambiguious.
  • Animal Motifs: Zeena's single, curved horn, curled tail, green hair, and green skin tone make her look rather chameleon-like, almost like a Distaff Counterpart of Espio.
  • Arrogant Kung-Fu Guy: Zavok.
  • Attack Of The 50 Foot Zeti: Zavok at his "full strength".
  • A Villain Named Zrg: They and their species name all share the first letter "z".
  • Ax-Crazy: Zazz is the most feral and manic of the Six.
  • Badass: Silliness aside, the title isn't just for show. They nearly succeed in destroying Sonic's world and, by extension, killing Knuckles and Amy. And they nearly turn Tails into a robot.
    • Actually, they DO succeed in the latter. It's just thanks to Tails' quick thinking that he retains his free will.
    • Badass Adorable: Zeena.
    • Badass Baritone: Zavok. Comes with the voice acting of Travis Willingham.
    • Badass Bookworm: Zavok and Master Zik.
    • Badass Grandpa: Master Zik is the oldest of the Deadly Six and is equally dangerous as the rest.
    • Badass Mustache: Master Zik. It reaches down to his legs!
    • Badass Normal: Unlike the other members of the Six, Zeena doesn't seem to have any real superpowers. That doesn't mean she's not dangerous.
    • Retired Badass: Master Zik founded the Deadly Six a long time ago (hey, he's only 1036) and, while having let his pupil Zavok take up the role of leader, still remains a part of the Six and is just as dangerous as he ever was.
    • Submissive Badass: Zavok has shades of this in his interactions with Master Zik. Though he is officially the leader of the Six, he still has enough respect for him to defer to him for advice.
  • Bad Boss: Notably averted with Zavok. Though he does get frustrated with the gang at times, he never punishes them. Especially shown when they accidently capture Tails instead of Sonic, he simply decides to improvise.
  • Bald of Evil: Zomom is the only member with no hair. Zik comes close to it, however.
  • Beware the Silly Ones: The Deadly Six are quite the Quirky Miniboss Squad. With each of their unique personality traits (Zazz's Blood Knight tendencies, Zomom's appetite, Zeena's narcissism, and Zor's nihilism), they're a barrel of laughter. But they're far from harmless and they truly live up to their title.
  • Big Bad: Of Sonic Lost World.
  • Big Eater: Zomom. He's practically gluttony personfied. During his boss fight, he holds a large piece of meat. He mentions wanting to eat Sonic, Tails, and Eggman several times. In one cutscene, Eggman even specifies getting the Six a large sandwich while angrily listing the things he did for them, and Zomom looks very ashamed.
  • Big Ol' Eyebrows: Zavok is the only one with eyebrows (well, a unibrow). And it's thick and cyan.
  • Blood Knight: Zazz likes fighting quite a bit.
    Zazz: I feel like destroying something!
    Zavok: That's what I like about you, Zazz. Always ready for a fight, even before you know what you're fighting.
    Zazz: You bet! Bring it on, and I'll rip it up!
  • Blow You Away: Zomom can create tornadoes by spinning.
  • Boisterous Bruiser: Zazz in spades. It helps that he has No Indoor Voice.
  • Bond Villain Stupidity: Zavok. Instead of personally supervising the roboticization of Tails, he and Zomom just leave him all alone in the lab. Being the Smart Guy he is, Tails successfully modifies the machine he's bound to to his own advantage. Though in fairness, it's not his fault alone. See Chekhov's Gun below.
  • Breath Weapon: Zavok can fire beams and fireballs from his mouth during the final battle.
  • Brilliant but Lazy: Zeena is far from stupid and no slouch in combat, but prefers to work on her nails more than anything else.
  • Brown Note: The Six are kept in line by Eggman blowing into a Cacophonic Conch, making a noise which causes them pain.
  • Carry a Big Stick: Zik wields a staff that's bigger than him. He usually stands on top of it.
  • Casting a Shadow: Zor is able to do this, combining it with Me's a Crowd to make shadowy copies of himself.
  • The Charmer: Zavok knows exactly what to say to convince Zeena to attack Sonic.
    Zavok: Why are you still here?
    Zeena: I'm just getting ready.
    Zavok: Well you seem to be taking your time.
    Zeena: Well it is my time to take now, isn't it?
    Zavok: Well what if I told you that you were the only one I trusted to be fast enough...
    Zeena: Oh?
    Zavok: smart enough...
    Zeena: Mmm-hmm.
    Zavok: ...and pretty enough...
    Zeena: Go on.
    Zavok: to beat the blue nuisance?
    Zeena: Well, I'd say you got the right girl for the job! (gets up, does a Hair Flip and leaves.)
    Zavok: Well, that was so easy I almost feel guilty.
  • Chekhov's Gun: Believe it or not, Zomom's giant sandwich, which he forgets on the roboticization machine Tails is tied to. After the Zetis leave him alone, Tails uses one of his tails to grab the toothpick stuck in the sandwich and uses it as a pen on the machine's touch screen to modify the program to his advantage.
  • Color-Coded for Your Convenience: They've each got one predominant color: red, pink, green, blue, orange/yellow, and purple.
  • The Comically Serious: Zavok and Master Zik's attempts to come off as intimidating are usually ruined by their teammates's wackiness.
  • Cowardly Boss: Zeena in her first fight. She never attacks directly and runs away when Sonic forces her out.
  • Creepy Shadowed Undereyes: All of them have this to some extent.
  • Cute Monster Girl: Zeena is the least feral looking.
  • Dangerous Forbidden Technique: Zor is able to use powers so dark and forbidden that none of the others dare use them.
  • Dark Action Girl: Zeena.
  • Deadpan Snarker: Zavok has his moments.
  • Delinquent Hair: Zazz sports a purple mohawk.
  • Disc One Final Boss
  • Disney Villain Death: Zavok and Zor both get baked in lava.
  • Disproportionate Retribution: Wanting revenge for being enslaved by Eggman? Understandable. Destroying the world and stealing its energy to do that? Overkill.
  • Dragon Rider: Zavok's boss fights involve him riding a robotic dragon.
  • The Dragon: Unwitting ones to Eggman at the beginning of the game, kept in line by the Cacophonic Conch.
  • Dropped a Bridge on Him: In the Wii U version. Well, you fight the Deadly Six fair and square, but the main issue are the deaths themselves. Zazz, Zomom, Zeena, and Master Zik are killed in-game rather than in cutscenes and they die like regular enemies. Zor and Zavok's deaths are a little more climatic, as they're baked in lava, but even then there's no big send off. They just... up and die. Though Eggman's line at the end of the game implies that they may not be gone for good.
    • Subverted in the 3DS version. They merely fly away after their final battles.
  • The Dog Bites Back: Once Eggman's Cacophonic Conch is kicked away by Sonic.
    Zavok: Strike, brothers! Make the fool pay for our abuse and enslavement!
  • Dumb Muscle: Zomom.
  • The Eeyore: Zor.
    Sigh... giving bad news is the one thing I actually enjoy.
  • Emo Teen: Zor's got the attitude and the look to match. The "teen" part, though, is pretty much out of the table.
  • Even Evil Has Loved Ones: Zavok does appear to genuinely respect his master.
    Master Zik: It would seem the peaceful days of tending my garden will have to wait while I take care of these matters the rest of you cannot.
    Zavok: Please, Master Zik; this is not something you should trouble yourself with. It's beneath you.
    • It also seems to be his relationship with the others as well. They all seem to be on a first name basis with each other, Zavok even calling them his brothers at one point. And though they do frustrate them at times, he never mistreats them. Though he's not above physical punishment if they severely disappoint him, as mentioned by Zazz.
  • Evil Albino: Zor.
  • Eviler Than Thou: The Six prove to be a greater evil than Eggman once they break free from his control.
  • Evil Is Petty: Zeena calls out Sonic for runing her nails during their last fight.
  • Evil Laughter: Zavok does this on occasion.
  • Evil Mentor: Master Zik is Zavok's master.
  • Evil Old Folks: Zik is the oldest of the team.
  • Evil Sounds Deep: Zavok and Zomom.
  • Expy: Hmm, a Quirky Miniboss Squad of six aliens that work for the Big Bad. Sounds like a certain band of Dragon Ball Z villains.
  • Extreme Omnivore: Zomom is said to "eat everything in sight" and threatens to eat Sonic and Eggman at different points.
  • Family-Unfriendly Death: It might not be an actual death (it's not really clear what happens to the Zeti in the end), but Zor falling into lava and welcoming it seems pretty messed up.
  • Fangs Are Evil: Zavok, Zazz, and Zeena. Though hers is more of a case of Cute Little Fangs.
  • Fat and Proud: Zomom will freely admit he's big. He won't react well to anyone else calling him fat, however...
  • Fat Bastard: Zomom, again.
  • Fingerless Gloves: Zor.
  • The Fighting Narcissist: Zeena, who is always seen painting her nails and values them above everything else.
  • Five-Bad Band: Although all of them are somewhat on equal footing.
    • The Leader: Zavok. He's the main instigator after the group betray Eggman.
    • The Dragon/Evil Genius: Master Zik is Zavok's chief adviser as well as his mentor. He's also the one who comes up with the plan to set a trap for the heroes in hopes of forcing them to their side.
    • The Brute: Zazz and Zomom are the most "hands on" when it comes to combat.
    • The Dark Chick: Zeena and Zor are the least physically imposing of the group, after Master Zik anyway.
  • Flat Character: All of their characterizations are rather minimal. They consist of long-established personality archetypes and little else besides that. Critic reviews panned them for this.
  • Flaying Alive: During his second fight with Sonic, Zazz explicitly threatens to skin him alive.
  • Flight: Zor during his second boss battle. The 3DS version gives them all the ability to fly.
  • Fragile Speedster: Zazz. He's fast enough to keep up with Sonic, but is weak without his Moon Mech backing him up and doesn't take many hits to defeat.
  • Genius Bruiser: Zavok and Master Zik are very strong and very smart. Notably, they set a good trap to capture Sonic, which is only foiled by Tails` intervention. Zavok also spends most of the game taunting Sonic over his continuing failures to save anyone.
  • Get Back Here Boss: Zavok's second boss fight combines this with Ring Out Boss. Sonic and Zavok fight on top a robot dragon and after taking damage, Zavok will retreat to another part of the robot. The final leg of the fight involves Sonic attempting to knock him off the robot dragon.
  • Glass Cannon: Though Sonic only starts fighting Zor pretty far into the game, he never requires more than three hits to take down. His second-most fragile teammate, Zeena, maxes out at six.
  • Good Old Fisticuffs: Zavok mainly uses his fists in battle.
  • Goth: Zor, with his gloomy expression, white skin, combover purple hair, and general "woe is me" personality, brings this to mind.
  • Hair Flip: Zeena does this at times.
  • Hair-Trigger Temper: Zazz has the shortest one of the lot.
  • Hartman Hips: Zeena has a bit of them.
  • Hey, It's That Voice!: Zavok is voiced by Relius Clover.
  • Hollywood Magnetism: The Six have the innate ability to manipulate electromagnetic fields, allowing them to take control of machines.
  • Horned Humanoid: All of them, though Zavok has the largest ones and Zomom has the most.
  • Hot-Blooded: Zazz.
  • In a Single Bound: They are all capable of leaping incredible heights and distances. The 3DS versioon gives them the ability to outright fly.
  • Kamehame Hadoken: Master Zik. Zavok seems to be able to do this as well, though it may be a result of becoming more powerful via Eggman's planet-draining machine.
  • Ki Attacks: Master Zik can do them, as can Zazz and Zomom when hopped up on Earth's energy.
  • Knights of Cerebus: Yea, the name isn't just for show. They nearly killed Sonic's world (and by extension Knuckles & Amy) by sucking it dry, and very nearly came close to turning Tails into a mindless drone. Even Sonic isn't joking around much anymore by the time he confronts them.
    • Laughably Evil: Unlike many previous examples in the series, however, they're evidently quirky and get in a lot of laughs along the way. By Word of God they were described as made to "bring a sense of danger and humor" to Sonic Lost World'' and they do it quite well.
  • Large Ham:
    • You can tell Liam O Brien was having fun with Zazz, as in every scene he's in he chews the scenery all the way.
    • Zavok, though more subdued than Zazz, has his moments. Par the course when you're voiced by Travis Willingham.
  • Lean and Mean: Zazz is the thinnest of the six.
  • Leitmotif: They have three variations of it:
    • One that's jazzy (played in their Zone 2 fights).
    • one that's orchestrated (played in Zone 4 fights and Zavok's Sky Road Zone 2 fight).
    • A chaotic mix played during the refights in Lava Mountain.
    • Zavok has his own leitmotif when fighting him in Sky Road Zone 4 and in the Lava Mountain refight before he turns giant.
    • And aside from their collective Leitmotif, they each have their own themes that play in cutscenes.
      • Zavok is accompanied by a sinister violin theme.
      • Master Zik's theme sounds like woodwind music that plays in Kung Fu movies.
      • Zazz has a Punk Rock theme that befitts his rock star appearance.
      • Zomom has a tuba that plays in his theme.
      • Zeena's Leitmotif is accompanied by a Sexophone.
      • Zor's theme is a somber piano mix of the Deadly Six theme.
  • Lightning Bruiser: Zavok and Zomom stand out as the physically strongest of the Six and are much faster than their sizes imply.
  • Make My Zeti Grow: Zavok's final fight with Sonic has him growing to a giant size while chasing him up a tower.
  • Me's a Crowd: Zor can make shadowy copies of himself.
  • Miniature Senior Citizens: Zik is the oldest and shortest member of the six.
  • Ms. Fanservice: Zeena, despite not having any real "attributes".
  • Names to Run Away From Really Fast: Oh, surely these "Deadly Six" guys wouldn't hurt a fly?
  • Narcissist: Zeena in spades.
  • Never Say "Die": Averted. With all of their colorful euphemisms, they help the whole game avert this trope and make damn well sure you know it.
  • Nonstandard Character Design: These guys wouldn't be out of place in Rayman Origins.
  • No Sense of Personal Space: Zazz, who gets all up in Sonic's face during the cutscene before their second fight.
  • Not So Different: In the Japanese version, Zor states that he and Sonic are very alike.
  • Obviously Evil: Zavok and Zazz do not look like the members most likely to cuddle Cream the Rabbit.
  • Older Than They Look: You thought Zik was old? Zazz is 127 years old!
  • Old Master: Zik is this to Zavok. He's even sometimes known as Master Zik.
  • Omnicidal Maniac: The Six plan to use Eggman's unstable Extractor machine to drain all the energy of Earth at once, destroying the planet itself as revenge for their imprisonment.
  • Our Demons Are Different: They're based on oni.
  • Overly Long Tongue: Zazz, who's tongue constantly hangs from his mouth.
  • Peek-a-Bangs: Zor's right eye is obscured by his hair.
  • Personality Powers: Some of the Six have powers that reflect their personality.
  • Pintsized Powerhouse: Zik is the smallest of the group, yet is just as deadly as the rest.
  • Planet Looters: Eggman's plan was to use his Extractor machine to drain the planet's energy and power his machines, but as it was unstable, he decided to drain a little bit at a time. The Six plan to use the machine to drain all of the planet's energy at once, thus destroying it and making themselves stronger.
  • Playing with Fire: Zavok can shoot fireballs during his final fight with Sonic.
  • Prepare to Die:
    Zavok: Your fate is to be destroyed. Why don't you just accept that? Lie down and die!
  • Punny Name: "Zavok" sounds similar to "havoc".
  • Puzzle Boss:
    • Zeena's first fight with Sonic. Zeena hides in snowmen during the fight and Sonic must destroy them all to draw her out. If he takes too long or hits a snowman with a bomb on it, the snowmen will reset, forcing him to start over.
    • Zor's fight in the 3DS version combines this with Timed Mission. Sonic is given 44 seconds to launch himself out of a cannon and attack Zor's Owl Mech and knock him to the ground or Zor will fire his laser. Compounding the difficulty is that he surrounds himself with fake Owl Mechs to confuse him.
  • Quirky Miniboss Squad
  • Ragin' Cajun: Zazz sports a slight, but noticible Cajun accent.
  • Ragtag Bunch of Misfits: An Arrogant Kung-Fu Guy, an Old Master, an Ax-Crazy Blood Knight, an Extreme Omnivore, a nihlistic goth, and a narcissistic Alpha Bitch.
  • Rapunzel Hair: Zeena.
  • Really 700 Years Old: All of them are at least a century old, yet still look fairly young (except Master Zik, who's over a millenium old).
  • Real Men Wear Pink: Zazz has magenta skin.
  • Recurring Boss: Each of the Deadly Six are fought three times throughout the game.
  • Recurring Element: A demonic monster who otherthrows Eggman as the Big Bad. However, this time there's six of them, and it happens at the beginning rather than the end. May also count as one in relation to Generations, as Eggman reclaims the Big Bad status from them after their defeat.
  • Red Oni, Blue Oni: The Six are all opposites of each other in some way. Bonus points in that they resemble actual demons.
    • Zavok is the red to Master Zik's blue, even reflected in their colors. And the two of them serve as the blue to the others' red.
    • Zazz is the red to Zomom's blue.
    • Zeena serves as the red to Zor's blue.
  • Restraining Bolt: Eggman tortures them with a Cacophonic Conch to keep them in line. Once Sonic kicks it away, the zeti bite back.
  • Red and Black and Evil All Over: Zavok.
  • Sadist: All of the Deadly Six display some level of sadism, though Zazz stands out among them as the most sadistic.
  • Sarcasm-Blind: Zeena, who takes Zavok's fake compliments and Sonic's Backhanded Apology at face value.
  • Saying Sound Effects Out Loud: Zor always says the word "sigh" rather than just sighing whenever he talks.
  • Sequel Hook: At the end of the game, Eggman says he'll find the Conch and control the Zeti again, implying they may not be gone for good. The theory is further supported by the 3DS version, where they fly away after their final battles with Sonic.
  • Sexophone: Part of Zeena's Leitmotif.
  • Shock and Awe: Downplayed, Zeti have the ability to control electrons. This is how the Deadly Six are able to control Eggman's machines.
  • Shockwave Stomp: Zomom's Signature Move.
  • Shout-Out: Zavok. Let's see... spiked accessories? Check. fire powers? Check. The ability to grow to giant size? Check. Looks like Zavok has a bit of Bowser in him.
  • Slasher Smile: Zazz's default expression, complete with a vicious laughter.
  • The Smurfette Principle: Zeena.
  • Something about a Rose: Zor carries a blue rose with him at (almost) all times.
  • Spikes of Villainy: Zazz, Zomom, and Zavok all wear spiked accessories. Zavok also has spikes on his body.
    • Zazz also has small spikes on his back. And lest we forget the fact that all six of them have horns.
  • Spin Attack: Zomom can spin himself around as an attack. Zeena also swings a snowman head around like an Olympic hammer in her boss fight.
  • The Starscream: They initially served under Dr. Eggman, but rebel against him after he loses his means of controlling them.
  • Straw Nihilist: Zor is this trope in spades. He's constantly depressed, never smiles, doesn't care if he wins or loses, and is apparently suicidal.
  • Supernatural Gold Eyes: It appears that all Zeti have yellow sclerae.
  • Super Strength: While all of them have this to varying degrees, Especially when they're hopped up on Earth's energy, Zavok and Zomom stand out.
  • Two Words: Obvious Trope: As Zomom eats his giant sandwich;
    Sonic: One word of helpful advice: diet and exercise.
    Zomom: That's three words!
  • Turned Against Their Masters: While initially working with Eggman, they very quickly decide to rebel. They also invoke this on Eggman's badniks.
  • Tunnel King: Zomom can burrow underground at tremendous speeds.
  • Vanity Is Feminine: Zeena.
  • Villainous Glutton: Zomom very clearly embodies this vice.
  • What Happened to the Mouse?: It's not really clear what happened to them after their final encounters with Sonic. At least in the Wii U version. In the 3DS version, all of them are shown flying away after being defeated at Lava Mountain.
  • What the Hell, Hero?: Master Zik will call out Sonic when beaten for the final time.
    Master Zik: You've beaten an old man. Are you proud?
  • Why Won't You Die?: Both Zavok and Zeena say this at different points.
    Zavok: Your fate is to be destroyed. Why don't you just accept that? Lie down and die!
    Zeena: Seriously still here? Why won't you just die?! Ugh! You're like a cockroach with a horrible fashion sense!
  • You Gotta Have Blue Hair: Zavok's cyan ponytail/unibrow. And Zazz's purple mohawk, Zeena's green Rapunzel Hair, and Zor's purple fringe.
  • Youkai: The Six are based on oni, and are known in Japan as "the Six Oni".
  • You Wouldn't Like Me When I'm Angry: Zazz's above quote.
