Characters / Sonic the Hedgehog - Antagonists

Go To

A list of all of the major antagonists, who don't belong to the Eggman Empire, throughout the series.

    open/close all folders 

    Tropes that define most of them 
  • Chronic Backstabbing Disorder: If they team up with Eggman, they have a tendency to do this.
  • Contrasting Sequel Antagonist:
    • Most of the villains follow a pattern that is quite the contrast with Eggman, especially from the Dreamcast Era and beyond.
      • From the Classic Era, Dr. Robotnik is a male Mad Scientist who turns anyone into robots. Witchcart is an evil witch that turns anyone into crystals.
      • Dr. Robotnik was an evil Token Human, while the Battle Kukku army are evil cartoon villains.
      • Eggman is an Affably Evil goofy villain that wants to take over the world with his robotic empire. Chaos, however, is a aquatic monster Woobie, Destroyer of Worlds known as the Destroyer Deity who served as his pawn in order to unleash The End of the World as We Know It, and was redeemed at the end.
      • Gerald Robotnik was a kind scientist who wanted to cure his granddaughter from a fatal disease, and created Shadow the Hedgehog in an effort to discover immortality. After the death of Maria at the hands of G.U.N., however, he decided to destroy the Earth in revenge against "the ungrateful humanity".
      • Eggman Nega is Eggman's descendant from the future, but unlike Eggman, he has none of the Affably Evil elements from his ancestor, and is a direct Ax-Crazy psychopath who wants to see an age of fear and chaos, and is even willing to get himself killed in order to achieve it. He also directly betrays Eggman and takes on his appearance (like Metal Sonic in Sonic Heroes) during the Rivals games.
      • Black Doom is an ancient alien overlord who sees humanity as food for his race, and wants to take over the world. Like Gerald, he is directly involved in Shadow's creation, but unlike Gerald who was an Anti-Villain, Black Doom is pretty much a bastard. Black Doom, unlike the other villains, is an antagonist to Eggman as he is to the heroes from the first minute.
      • Mephiles the Dark and Iblis are the components of a entity known as Solaris, but unlike Chaos, they have no tragic elements to their name. Mephiles is directly a Satanic Archetype and a Manipulative Bastard who wants to reunite with Iblis at some point in time in order to destroy the world as we know it, using Time Travel to mess with the heroes' heads. Like Black Doom, he also tries to manipulate Shadow to join his side, but while Black Doom talked from a creator and alien perspective, Mephiles is a nihilist who asks Shadow why he fights for humanity if they will persecute him later. Mephiles also never interacts with Eggman, and is the only Hero Killer in the series.
      • Erazor Djinn is the most independent villain in the series: he is an evil genie from the Arabian Nights who wants to become the Arabian Nights itself by rebuilding the world in his image. He, however, decided to use Sonic and Shahra as his means to obtain the Seven World Rings, and becomes an incomplete monster at the end. He has no relation with Eggman whatsoever, due to the good doctor being absent from the game.
      • Merlina summons Sonic to her world in order to obtain King Arthur' scabbard. However, Merlina acts as a Suspiciously Similar Substitute to Shahra (even looking identical to her) in order to subvert the players expectations and to trick Sonic. Unlike Erazor Djinn, Merlina is an Anti-Villain who wants to prevent the tragic fate of the Grand Kingdom, and is redeemed at the end.
      • Dark Gaia is an ancient deity who has a good counterpart with Light Gaia (Chip), and unlike Chaos, has no tragic backstory and acts more as a force of nature, and his actions has severe consequences for Sonic's world (breaking the entire world and possessing people). Unlike Chaos, Dark Gaia was never allied with Eggman (and in fact was used as a power source by Eggman to create Eggmanland) and proceeded to blast Eggman away after being freed and reborn in full in order to fight Sonic and Chip by himself.
      • The Deadly Six are a group of genocidal demons who want to destroy Sonic's world in retribution to Eggman enslaving them and make themselves stronger from doing so. Zavok in particular is a more serious villain than Eggman's Affably Evil villainy.
    • Infinite is quite a foil to the different villains in the franchise outside of Eggman.
      • Infinite, unlike any the other antagonists in the series (Chaos, Metal Sonic, the Deadly Six, etc.), is an ally of Eggman on equal terms instead of some kind of pawn. Likewise, Infinite never betrays Eggman, like Shadow or Eggman Nega.
      • Infinite is pretty similar to Mephiles the Dark, as an Ax-Crazy dark figure with hellish powers who wants to see the destruction of the world as we know it, who are in part motivated by Shadow the Hedgehog. However, Mephiles was part of the deity known as Solaris, while Infinite was formerly a normal person like Sonic and gang.
  • Recurring Element: The villains share some patterns.
    • Many of them are Dragons or Big Bad Duumvirates to Eggman, and will at one point or another betray the doctor. (Captain Whisker and Infinite are exceptions.)
    • Many will turn into a giant monster at the end, and Sonic will need to turn into Super Sonic (or something else) to defeat it. (Void, Zavok, and Infinite are exceptions in that they are defeated without any Eleventh Hour Superpowers despite becoming giant monsters.)
  • Villain of the Week: Most of them only appear as an antagonist in the game they debuted, never to be seen again or be mentioned. This is usually due to them being either captured, in Dark Gaia's case, defeated and lain dormant, or deceased within the game they debut in.

Classic Era

    Nack the Weasel, a.k.a. Fang the Sniper

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 the Hedgehog Triple Trouble. He made a few cameos, mostly in spinoffs.

  • The Bus Came Back: He makes an appearance as a boss fight in the second act of Mirage Saloon of Sonic Mania (well, it's Heavy Magician impersonating him anyway).
  • Chuck Cunningham Syndrome: Hasn't been seen in the game series in years, although he made a cameo on a wanted poster in Sonic Generations (which lists both names together, suggesting that Nack is his real name and Fang is his alias similar to the situation with Robotnik and Eggman). Fang eventually showed up again in Sonic Mania, albeit as an illusion used by Heavy Magician.
  • Combat Pragmatist: Heavily relies on dirty tactics in all of the games he appears in:
    • His first fight in Triple Trouble has him attempting to activate a flame trap. In his fourth fight, he fires a heat-seeking missile at you.
    • In Sonic the Fighters one of his attacks is stomping on the opponents foot, which leaves them open for another attack.
  • Cool Bike: His airbike, the Marvelous Queen.
  • Dimensional Traveler: He's actually from the same dimension that the Special Stages are set in.
  • Dirty Coward: Oh boy, where to start. He runs away from you every time you defeat him in his debut appearance for one thing.
  • Family-Friendly Firearms: His Popgun. It was originally going to be a full-on revolver with bullets.
  • Fangs Are Evil: Why else do you think his name is Fang?
  • Fighting Clown: One wonders why he choose a cork gun of all things instead of actual firepower.
  • Four-Fingered Hands: He's depicted with this in most media he appears in, odd considering how nobody else in the series has this trait. Common fan theories attribute this to either Yubitsume due to his presumed criminal past or how he's from another dimension.
  • The Gunslinger: In a sense considering how he doesn't use actual firearms despite his moniker, although he does sport a cowboy-ish look at the very least.
  • Greed: A treasure hunter who's only in it for the money. The only reason why he wants the Chaos Emeralds in Triple Trouble is not for their power but because they would fetch him a hefty profit.
  • Harmless Villain: In Sonic the Hedgehog Triple Trouble, he serves as the boss of the special stages but is not particularly effective:
    • In his first boss fight, he presses a button to set a flame trap on you but then accidentally unleashes it on himself somehow.
    • In his second boss fight, he bounces around on a spring but his panicking facial expressions indicate he has little control over his ride. The spring bounces low to the ground, making it easy to jump on top of him.
    • In his third boss fight, he cackles villainously as he flies around in his airbike, which gets smacked into the sky after just three hits.
    • In his fourth boss fight, he once again cackles villainously as he sends a heat-seeking missile to hurt you. After about fifteen seconds, the heat-seeking missile changes targets and hits him instead, ending the bossfight.
    • In his final boss fight, he attempts ramming you from above with the drill of his airbike. After a few attempts, the drill gets him stuck into the ground, allowing you to push him down further, all while he has a panicked facial expression.
    • Towards the finale, he reappears again prepared to fight you... and then promptly runs away in terror when Eggman approaches.
    • When Fang shows up, he is usually sleeping.
    • When he runs away, he has a tendency of tripping over his own two feet before picking himself up and continuing to run.
  • Improbable Weapon User: His signature weapon in Sonic the Fighters is a cork gun.
  • Informed Species: Fang's official profile on Sega of America's Sonic Central website once called him a "wolf weasel", which was apparently earlier stated on the English fan site Concept: "Mobius" and in turn was traced back to the Japanese fan site Sonic Dimension. However, that turned out to be a mistranslation; "wolf jerboa" would be more accurate. Character Designer TOUMA indeed confirmed that Fang was conceptually based on a jerboa (explaining his features, tail shape and bounce, and number of fingers), and clarified that the weasel part was a change made overseas. It's currently unknown where the wolf half comes from, but Sonic Dimension based its data on official Japanese sources, so it's generally believed to be accurate as well.
  • Nice Hat: Wears a Stetson hat that would give OVA!Knuckles a run for his money.
  • Nonstandard Character Design: He's portrayed with Four-Fingered Hands in most media he appears in rather than the usual five, likely because jerboas have four toes on each foot.
  • Prehensile Tail: One of his moves in Sonic the Fighters has him somehow grabbing the opponent and throwing them with his tail.
  • Revolvers Are Just Better: Well, toy revolvers if that's your thing. He was originally supposed to have an actual revolver in his debut appearance but it was scrapped later in development.
  • Token Evil Teammate: In the story of Sonic the Fighters, each of the game's Chaos Emeralds are guarded by one of Sonic's friends with the exception of Fang, who stole his emerald from one of those guards.


The main villain of Tails Skypatrol, which is her sole appearance. Her goal is to take over an island with her three henchmen and turn anyone who opposes her into crystals. She rides in a mine cart and attacks with magic sparks.

  • Ambiguously Human: She certainly looks like a cartoon human, and this presumably makes her the only human character besides Eggman to appear in the pre-Sonic Adventure games.
  • Big Bad: Of Tails Skypatrol. Eggman is completely absent from the game and she's the driving threat in his stead.
  • Everyone Calls Him "Barkeep": Her name is just Witchcart, and no real name was given to her in the games.
  • Generic Doomsday Villain: She is given no characterization at all beyond "Evil witch who wants to take over an island and turn people into crystals".
  • Haunted Castle: Her lair is the final level of the game, DarkCastle Area.
  • Meaningful Name: She's a witch who rides in a cart.
  • Mecha-Mooks: She has a modest army of machines at her command along with her henchmen and the obstacles set up to counter Tails.
  • Minecart Madness: Villainous example, since a cart is Witchcart's ride of choice.
  • Offstage Villainy: We don't get to see her turning anyone into crystals.
  • Outside-Genre Foe: Witchcart is more like a villain out of a fairy tale than the supervillain-level threat Eggman posed; she was the first antagonist in the series to directly use magic instead of just robots to accomplish her goals, predating the more significant use of this kind of threat with Chaos in Sonic Adventure. Most notable is that her use of magic does not involve the use of the Chaos Emeralds, which are completely absent from Tails Skypatrol.
  • Punny Name: Her name is a portmanteau of Witchcraft and Cart.
  • Sinister Schnoz: Has one on loan from the Wicked Witch of the West.
  • Taken for Granite: What she threatens Tails with — she claims to have the ability to turn people into crystal. In-game, the only magical prowess she displays is shooting magic sparks at Tails.
  • Terrible Trio: Her minions.
  • Token Human: Before Sonic Adventure, she was the only human (or human-like) character that appeared in the games besides Eggman.
  • Villain of the Week: A minor oneshot villain who had the merit of being in one of the very few games in the franchise where Eggman is completely absent. Tails defeated her, and she was never seen in the games again.
  • Witch Classic: She wears black clothes and a pointy hat, uses magic as her primary method of attack, and has three henchmen.
  • Wicked Witch: The very picture of one.

    Great Battle Kukku XV

The main villain of Tails Adventure, which is his sole appearance. He is the evil ruler of the imperial Battle Kukku Army, and led his forces to Cocoa Island in the hopes of seizing the legendary Chaos Emeralds and using their power to Take Over the World.

    Battle Kukku XVI / "Speedy"

Son of the Great Battle Kukku and heir to the position of the Battle Kukku Army's leader.

  • Eggshell Clothing: He appears to be wearing one as part of his uniform.
  • Overlord Jr.: The son of Great Battle Kukku XV, and one of the main villains of the game.
  • Recurring Boss: He's faced twice; once in a race on Polly Mountain, and later as the penultimate boss in the Battle Fortress.
  • Villain of the Week: Like his father, he is a one-shot villain whose sole appearance was in Tails Adventure.

    Doctor Fukurokov

A scientist who works for the Battle Kukku Army.

Dreamcast Era

Click here to see Perfect Chaos 

A water being that originally acted as a guardian of Chao but went on a rampage when they were attacked by Pachacamac's clan and was sealed inside the Master Emerald by Tikal. Robotnik eventually set him free, but Sonic was able to calm him. Was the Final Boss of Sonic Adventure, and makes occasional other cameos.

  • All There in the Manual: Sonic Channel says he's a Chao mutated by Chaos Energy. Most likely he could've mutated from a Neutral Chaos Chao, as they resemble a Ridiculously Cute Critter version of his base form.
  • Art Evolution:
    • Perfect Chaos gets somewhat of a redesign in Sonic Generations, gaining a chitinous, reptilian scale-like armor on his back, a glowing orange brain and greenish energy emanating inside it. According to Word of God, this was how he was supposed to look like in Adventure, but the limitations of the Dreamcast was what forced Sonic Team to go with the less detailed model in that game, which presumably also leaked into the FMV cutscenes with them having to use that design instead.
    • The advances in technology have really done wonders for his watery look, as seen in his appearance in Sonic Forces.
  • Attack Its Weak Point: All of his forms share one singular weakness: His exposed brain, the only part of his body tangible enough to attack.
  • Attack of the 50-Foot Whatever: Chaos 0 is barely taller than Sonic. His Perfect form grows to be higher than a skyscraper.
  • Berserk Button: Don't threaten Chao. Ever.
  • Beware the Quiet Ones: Chaos never speaks and is perfectly content to be left alone... until you harm the Chao. At which point, the only thing you can do is get your affairs in order.
  • Blob Monster: Made primarily of water.
  • Breath Weapon: Perfect Chaos can fire beams of energy from his mouth.
  • The Brute: Chaos 2, who's more of a Top-Heavy Guy compared to his first two forms and gains a barrier move to shield from attacks.
  • Chaos Is Evil: Presented as this at first in Adventure, but stops being hostile after being calmed down.
  • Demoted to Extra: He has no real role in Sonic Battle's plot; his appearance is just due to his popularity and for the sake of having Emerl copy skills from him.
  • Destroyer Deity: Referred to by Eggman as "The God of Destruction". Considering everything he was capable of, especially after absorbing all the Chaos Emeralds and almost destroying the entire world the first time around, Eggman is more than right for the "destruction" part.
  • Disproportionate Retribution: Pachacamac's clan killing fellow Chao, as well as trying to steal the Chaos Emeralds, enraged him so much that he not only outright killed the Echidnas (offscreen), he almost tried to destroy the entire planet.
  • Doing In the Wizard: The games seem to portray him as an actual deity that the Echidnas worshiped, even though some sources confirmed he's just a mutated Chao.
  • The Dragon: To Eggman in Sonic Adventure. Elevates to Dragon-in-Chief after Eggman loses his grip on Chaos' reins and Perfect Chaos is realized.
  • Dragon with an Agenda: He was in league with Eggman the whole time just to get a hold of the Chaos Emeralds, and when Eggman fails too many times, he decides to go it alone.
  • Eldritch Abomination:
    • His final form. It looks very much like Biollante, but with fewer tentacles, and being made of water instead of plant-materia. Its screams and roars are also rather Godzilla-esque.
    • Chaos is supposedly a Chao that was mutated eons ago. If that is the case, he has always been an Eldritch Abomination by that point.
  • Evil Knockoff: The Chaos shown in Sonic Forces is revealed to be a Virtual Reality construct created by Infinite with the power of the Phantom Ruby.
  • Final Boss: Three times: Chaos 6 is the final boss for both Knuckles and Big, and Perfect Chaos is the true final boss that must be defeated as Super Sonic.
  • Flat Character: Barring his vengeance-driven motives, Chaos is surprisingly nondescript in personality for what was a major character in Adventure, not helped by his lack of expressiveness and voicelessness. The closest glimpse we get to his personality is Tikal saying that "He's a very loving and gentle creature." in one of the flashbacks.
  • Foreshadowing: Chaos was alluded to as early as the prologue in the manual for the Japanese version (as well as the PC version) of Sonic the Hedgehog 3, where Knuckles speculated that the crashed Death Egg in the lake of the Floating Island was the egg containing a legendary dragon that was fated to destroy the world. Guess what Perfect Chaos resembles?
  • From Nobody to Nightmare: At first, he was just a mutated Chao living in peace with Tikal and other Chao. Then the rest of Pachacamac's clan tried to take the Chaos Emeralds for themselves, killing many Chao in the process. That resulted in Chaos earning his title.
  • Good Is Not Soft: He's pretty peaceful and friendly towards Tikal and the Chao. But if anyone harms them, he won't hesitate to kill.
  • Heel–Face Revolving Door: Not unlike Shadow, he has gone through this. He started out as the guardian of the Emeralds and the Chao, then went berserk and become the antagonist in Sonic Adventure, before being pacified at the end of the game.
  • Hellish Pupils: Perfect Chaos has reptilian eyes. They are highlighted in his introduction in both Sonic Adventure and Sonic Generations, with the pupils getting thinner as he sets his sight to the hedgehog.
  • He Who Fights Monsters: Tried to avenge the Chao when they were attacked by a power-hungry tribe of Echidnas only for its anger to quickly went out of control; to where it wanted the entire world to feel his anger and sadness through destruction, inadvertently endangering the lives of more Chao.
  • Immune to Bullets: At the beginning of Sonic's story in Adventure, a group of police attempt to shoot Chaos but retreat when they realize that their guns don't work. Justified as his body is made out of water, so bullets will just go right through him.
  • It Can Think: Especially when he's shown to have feelings and when he goes rogue against Eggman in search for the Chaos Emeralds the second time around, making it clear that he's had enough of playing games.
  • Kaiju: As Perfect Chaos, he could be a Shout-Out to famous Kaiju Biollante.
  • Kill It with Ice: Chaos 6, in Sonic's and Knuckles' version of the fights, must be frozen with Eggman's bombs before being attacked.
  • Knight of Cerebus: Chaos was the first significant Sonic antagonist to have no humorous quirks or traits whatsoever, and the threat he brought is far greater and darker than anything previously seen in a Sonic game. He's also the first character in the series to have (canonically) killed another character — specifically, he nearly drove the Echidna race to extinction.
  • Mad God: In Sonic Adventure. Of course, the "mad" in this case refers more to unquelled rage than actual insanity.
  • Making a Splash: His trademark ability is hydrokinesis. His first form is only able of manipulating his body and small puddles, but his "Perfect" form is able to flood Station Square indefinitely.
  • Mighty Glacier: Especially in Sonic Battle. Next to Emerl, he's the strongest character in the game, but has the slowest walk speed and dash in the entire roster.
  • More Teeth than the Osmond Family: Perfect Chaos has a lot of teeth.
  • Mutants: He's a Chao that was mutated long ago.
  • My Brain Is Big: Subverted: in his first form, his brain isn't really big, but it's still more visible due to his form. It does grow somewhat in size, though, when he eventually becomes his Perfect form. On top of that, it also glows.
  • Names to Run Away from Really Fast: Chaos' name refers to his unpredictable and destructive behavior, although it also alludes to his relationship with the Chao and the Master Emerald.
  • Not Evil, Just Misunderstood: Chaos' actions during the course of "Sonic Adventure" were fueled by his grief and desire to avenge the Chao he protected. He immediately calms down when Sonic, Tikal and the others show him that the Chao in the present day are living in peace and happiness.
  • Olympus Mons: Once a Chao, Chaos mutated into his current watery form thanks to prolonged exposure to the Master Emerald.
  • One-Winged Angel: Has seven of these, each one stronger than the last, the transformations for which occur every time he absorbs a Chaos Emerald, culminating in Perfect Chaos.
  • Outside-Genre Foe: Whereas Eggman relied on machinery and simply intended to use the Chaos Emeralds as a means to an end, Chaos was the first major villain in the series to rely on (supposedly) supernatural powers to achieve his goals, and unlike the one-shaded goals of Eggman, Chaos is driven by a vengeful rage to use its power to destroy the entire planet. Even Eggman is left at his mercy when he reaches his full power as Perfect Chaos. He is also the first character in the series to have explicitly killed another character — specifically, he drove the entire Echidna race to near-extinction.
  • Out of Focus: Despite his Heel–Face Turn at the end of his debut game, he only rarely appears in the series, likely because it'd be hard to write plots where such an overpowered character would fit. Sonic Battle, one of his few non-cameo roles, tries to explain that he'll only intervene in times of great disaster, which raises the question of where he was when a space station was going to blow up the planet, or when Solaris was going to destroy all of time, or when the planet was split into several pieces by Dark Gaia, etc. Even when given a starring role and marketed pretty hard in Sonic Forces, it turns out to all be a total lie — even sidestepping the fact that the Chaos in that game is an impostor made by Infinite, he only gets major focus in two cutscenesnote , and gets taken out in the second one — by Classic Sonic, of all people.
  • Papa Wolf: To the Chao.
  • Perpetual Frowner: Has a permanent glare.
  • Person of Mass Destruction: His Perfect Chaos form, demonstrated when he flooded Station Square with ease and would have done the same to the world if he wasn't stopped.
  • Physical God: Known as the God of Destruction.
  • Plot Armor: Gains some of this in the Super Sonic Story in Sonic Adventure as he managed to defeat Eggman and Knuckles despite getting defeated in more powerful forms unless that was on purpose.
  • Promoted to Playable: In some games he appears in, such as Sonic Adventure 2 and Sonic Battle.
  • Puzzle Boss: Chaos 6. When fought with Sonic and Knuckles, he has to be frozen before you can even attack him, while Big's version of the Chaos 6 battle has him try to fish Froggy out, which can either be ended in under 10 seconds, or be a long drawn-out struggle with rarely any chance to attack.
  • Reptiles Are Abhorrent: Perfect Chaos, which gains a lot of reptilian features to the point of looking like a Sea Monster.
  • Sealed Evil in a Can: Chaos was sealed in the Master Emerald by Tikal for thousands of years due to him going berserk, only to be freed by Dr. Eggman when he shatters the Master Emerald. It should be noted, however, that Chaos isn't actually evil — just angry and vengeful.
  • Semi-Divine: May as well be the case as despite having near supernatural powers, it's otherwise stated that he was just a mutated Chao.
  • Shapeshifter: By virtue of his water-based form.
  • Shout-Out: Perfect Chaos is very similar to Biollante, with the redesign in Sonic Generations further adding to this.
  • Sickly Green Glow: Perfect Chaos' Generations design has him glow greenish energy from the inside. The same applies to his teeth.
  • Sinister Scythe: In a very bizarre and surreal Transformation Sequence as Chaos 6. He shapeshifts into a sort of vase thing, shoots tendrils everywhere to corner the player character, then slashes downward with his tail that forms into a glowing scythe.
  • Some Kind of Force Field: Chaos 2 can project a barrier during the boss fight.
  • The Speechless: Though Chaos never talks, he is able to communicate with Tikal through ripples in the water. Though what he says isn't translated, however.
  • The Starscream: Attacks Eggman when going after the Emeralds again; he was just waiting for the perfect opportunity to steal them all and become his final form.
  • Super Mode: Perfect Chaos is Chaos' equivalent of the Super State, at least through the Chaos Emeralds' negative energy. It's currently unknown if Chaos reacts to their positive energy like the other characters with Super States do or assumes his Perfect form either way.
  • Super Not-Drowning Skills: While it's very situational, he can't drown in Sonic Adventure 2.
  • Threatening Shark: Chaos 4 looks somewhat shark-like.
  • The Unfought:
    • Chaos 1. Eggman doesn't sic him on Sonic and Tails after he steals their Chaos Emerald, and by the time Knuckles follows Eggman to the Station Square hotel, the latter feeds Chaos another Emerald before sending him to attack the echidna.
    • In Forces, he and Shadow are the only members of Eggman's team to not be fought.
  • The Unseen: Chaos 3 and 5, due to absorbing two Emeralds at once in both instances when becoming both Chaos 4 and 6 respectively.
  • Unstoppable Rage: Extra emphasis on rage. Harming Chao will turn Chaos genocidal.
  • We Hardly Knew Ye: Chaos in Forces only appears in one cutscene of his own and isn't seen again until the war sequence near the end of the game after being defeated by Classic Sonic.
  • Well-Intentioned Extremist: His turn into an antagonist was triggered by a power-hungry tribe of Echidnas trying to steal the Chaos Emeralds, and killing several Chao via trampling in the process. While his desire was to avenge the Chao, his anger quickly went out of control to where he wanted the entire world to feel his anger and sadness through destruction.
  • Woobie, Destroyer of Worlds: He was a Chao that at some point was mutated by chaos energy and made it his sole duty to protect the other Chao from any threats he perceived, and was initially peaceful towards most people as shown with Tikal. When Pachacamac's clan went for the Emeralds and killed some Chao in the process, he went into a total genocidal rage and was forced to be sealed inside the Master Emerald by Tikal so the whole world wouldn't be destroyed.
  • You Are What You Hate: Hates anyone who would harm Chao, and when his anger quickly went out of control in Sonic Adventure, he inadvertently threatens the lives of the Chao when he ruins Station Square and the Chao Garden it contains.

"Tikal, the seven Emeralds are essential to our survival. It is for the good of all our people."

Voiced by: Tōru Ōkawa (Japanese), Steve Broadie (English)

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

  • Anti-Villain: He did what he did because he believed he was genuinely helping his tribe.
  • Asshole Victim: Killed by an enraged Chaos during his bid for the seven Chaos Emeralds and the Master Emerald.
  • Abusive Parents: It says a lot when he's willing to have his soldiers trample his own daughter in his pursuit of power.
  • Eyes Always Shut: Always has his eyes shut in Sonic Adventure, though they're textured on his model, as seen above.
  • Fatal Flaw: Greed and Wrath.
  • Ironic Name: Named after the early South American civilization of the same name which was initially peaceful before being invaded by the Incan Empire and later the Spanish; Pachacamac is the warmonger in question as shown with his relationships with other Echidna tribes and Chaos.
  • Killed Off for Real: Notable for being among the first major characters to die in the series, albeit offscreen.
  • Predecessor Villain: Of Adventure. He's the indirect cause of everything that has happened, but long dead by the events of the game proper.
  • Small Role, Big Impact: Pachacamac didn't have a lot of screentime or characterization, but his actions led to the extinction of his own species and nearly doomed the world centuries later.
  • Villain with Good Publicity: All his subjects except his daughter Tikal respect and share his martial prowess and ambitions.
  • Well-Intentioned Extremist: He only wanted the best for his people, but was so filled with greed with the power of the Emeralds, it ultimately led to the extinction of his entire race.

"Am I alone? I am not alone... My friends, my brothers, I want to be whole..."

Voiced by: Urara Takano (Japanese), Lani Minella (English)

The main antagonist of Sonic Shuffle. He represents negative feelings. Following his creation, Void sought the Precioustone to become whole, but his dark powers caused destruction all over Maginaryworld.

  • Anti-Villain: Void is unique among other rogues in the series, as his motivation is to fill out his own emptiness, not a lust for power, control, revenge, or destruction.
  • Casting a Shadow: Void commands the power of darkness.
  • The Corruption: He inadvertently does this to each dream world he passes through, turning them into radically different environments that are slowly destroying them and Maginaryworld.
  • Dark Is Not Evil: Despite being the embodiment of darkness, he doesn't intend to be evil.
  • The Eeyore: Always in a state of sadness and depression due to being the embodiment of negative feelings and also because of his separation from Lumina.
  • Eldritch Abomination: Void's monster form. Its head is its chest, and it has multiple eyes poking out of it.
  • Fusion Dance: Does this with Lumina to bring back Illumina.

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

Voiced by: Chikao Ohtsuka (Japanese), Marc Biagi (English, 2001), Mike Pollock (English, 2005)

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 shut down, 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 unleash Shadow.

  • Anti-Villain: He was so desperate to save his granddaughter that he made a deal with Black Doom to speed his research. And after the government either ran out of patience or got wind of his outside interference, they went in and killed everyone, driving him off the cliff. This is especially noticeable in Shadow The Hedgehog, as he is treated as some sort of Big Good.
  • Badass Bookworm: It's simple. He created Shadow, the whole plan 50 years before it happened, and the Prototype that Sonic and Shadow used lots of effort in defeating.
  • Big Good: Amusingly. At first glance, Gerald seems like a rotten guy like his grandson would end up being, but the Final Story in Shadow The Hedgehog reveals he was planing to use the means given to him by the Black Arms against them. Keep in mind, however, he was only this as Maria was alive. After that, he decided to destroy the planet in revenge.
  • Broken Pedestal: Dr. Ivo Robotnik idolized Gerald, but after the events of Sonic Adventure 2... not so much. Eggman, however, seems to gain some of his respect back after discovering Gerald's secret plan against the Black Arms.
    Eggman: That's it, is brilliant!
  • 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: 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.
  • First-Name Basis: Even among those who knew him, he's usually referred to as Prof. Gerald, not Prof. Robotnik.
  • Humans Are Bastards: Developed this mentality after Maria died.
  • Killed Off for Real: Executed by a firing squad.
  • Knight of Cerebus: One of the few villains in the franchise with no comedic traits whatsoever due to his tragic fate.
  • 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, beginning his work on Shadow as his ultimate and parting gift to Ivo.
  • 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: Has been long dead by the time Eggman finds Shadow. However, his plan to destroy the Earth by crashing the ARK into it keeps going on even fifty years after his death.
  • Predecessor Villain: Everything in Sonic Adventure 2 that happens is because of this guy, even though he's been dead for 50 years. Can also count as one for the franchise as a whole, as it was Eggman's reverence towards his grandfather that got him interested in studying robotics in the first place.
  • 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 he'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.
  • Ungrateful Bastard: His Final Speech includes him calling humanity as a whole this. Considering he was trying to help mankind with his intelligence and even Shadow and the Eclipse Cannon were intended to save them all from Black Doom, how he developed this mentality is rather easy to see.
  • Villainous Legacy: He was behind the plan in Sonic Adventure 2 50 years ago before the event, and possibly Eggman becoming who he is today. Likewise, his notes about the Gizoid who would be known as Emerl starts the events of Sonic Battle.
  • Woobie, Destroyer of Worlds: He hates humanity with all his heart, but only because they took his granddaughter from him.

    The Biolizard

The prototype of the Ultimate Life Form, AKA Shadow the Hedgehog. Also part of Gerald Robotnik's plan to destroy the Earth, where during its second battle it is instead known as the Finalhazard. Only appears in Sonic Adventure 2 and the 3DS version of Sonic Generations.

  • Achilles' Heel: Both its low stamina (due to not being as advanced as Shadow) which cause it to tire out easily, and the life support system on his back, which when destroyed eventually causes other weak points to appear on its body via the harsh conditions of space when it attempts its final act.
  • Animalistic Abomination: a deformed lizard-newt thing with enough control over chaos energy to drag the space colony ARK to earth. In addition, it's unclear how intelligent it is: thought it's at least smart enough to follow it's creator's orders.
  • Breath Weapon: Can fire dark energy spheres from his mouth.
  • The Bus Came Back: After a long absence, a temporally displaced Biolizard makes a reappearance as the second boss in Sonic Generations 3DS.
  • Colony Drop: Tries this by fusing with the ARK in the final phase of its boss fight, so it can fulfill Gerald's plan.
  • Damage-Sponge Boss: He takes the most hits out of any of the Adventure series bosses. Even its skin can sometimes cause Shadow to take damage if he hits it head-on at certain angles during the initial fight.
  • Dragon-in-Chief: Keeps Gerald Robotnik's plan going, even after Gerald is dead and Shadow has made a Heel–Face Turn.
  • Dragon Their Feet: Effectively this in-universe, as it doesn't reawaken until long after Gerald is dead.
  • Dual Boss: Inverted in his second fight, as it's Shadow and Sonic vs. him.
  • Evil Cripple: It has a life-support system, which acts as its weak point in the first fight against it. It also has two stumps around where its hind legs are, as well as an extra one for where its left hand used to be when it fuses with the ARK.
  • Generic Doomsday Villain: It's less of a character and more of an extension of Gerald Robotnik's vengeance.
  • Final Boss: Of Sonic Adventure 2, first fought with Shadow and then Super Sonic and Super Shadow.
  • Flawed Prototype: Despite being an "ultimate lifeform," it's missing a few limbs and is dependent on life-support to survive. Not to mention it's much larger than shadow, implying the latter's design is more space-efficient.
  • Giant Space Flea from Nowhere: There's one scene that it appears in before it fully enters the plot, and it doesn't explain anything about it other than it might be the "original" Ultimate Lifeform. It has very little characterization and seems to only exist for the sake of a boss fight.
  • Gravity Master: When low on health, it will mess with the gravity in the room, forcing Shadow to float towards his life support system while avoiding the pink orbs.
  • Handicapped Badass: Overall, while it had to be maintained through a life support system, during its time it did cause quite a few problems aboard the ARK before being sealed away in the core. During the fight against it with Shadow, it also effectively has him pincer-ed between its head and tail and overall is quite durable and due to being a lizard, can regenerate at a fast rate.
    • Also applies to its Finalhazard form, which is attached to the ARK, and therefore loses what little mobility it had. It compensates for this with deadly point-defense lasers.
  • Outside-Context Problem: No one had any clue about its existence until it attacked Shadow and then attached itself to the ARK.
  • Punny Name: It's a living weapon (bio-hazard) and also a reptile (lizard), hence the name BioLizard
  • Psycho Prototype: To Shadow, the Ultimate Life Form.
  • Reptiles Are Abhorrent: To the point where during its creation, it became very primal and difficult to control, as well as reacting violently around the Chaos Emeralds; it had to be sealed away deep within the ARK's core to prevent ongoing issues. It was also enough to have some stray researchers who feared its existence and the damage it caused to leak the classified information about Project Shadow to GUN, which led to the events that would prompt them to soon try to close down the experiments.
  • Robeast: Had to be outfitted with cybernetic implants to be properly stabilized, especially with all of those tubes around it that connect it to the aforementioned life support system.
  • Ultimate Lifeform: Intended to be this, but its aggressive behavior and its reliance on the life-support system to survive caused it to be deemed a failure.
  • Timed Boss: In the second fight, you have your rings to watch as he slowly descends toward Earth. And even then, you only have five minutes before it enters the planet's atmosphere and it's an automatic death.
  • Vader Breath: He does this mixed with a panther growl.
  • The Voiceless: It does roar, though.

    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)

The leader of the Black Arms, an alien race from the Black Comet, who helped create Shadow and tries to enlist his help in conquering the Earth.

  • Abusive Parents: After helping Gerald in creating Shadow, he used him for his own benefit and had no problem with trying to kill him for disobeying him.
  • Aliens are Bastards: Well, yeah, pretty much. The Black Arms are a race that feeds on the many planets it invades, and Black Doom wants to destroy Earth's civilization and use the humans as food for his people. Black Dooms also commits atrocities, which involves: the invasion of the planet, killing and consuming many of its citizens, destruction of the Presidential White House, all of this, while hypocritically describing Humans Are the Real Monsters to Shadow.
  • Arch-Enemy: To Shadow, moreso than any other villain in the series, as he is personally involved in the way Shadow came to be.
  • Archnemesis Dad: Created Shadow, but is perfectly willing to destroy him for defying him.
  • Authority Equals Asskicking: The leader of the Black Arms and the most powerful of them all.
  • Big Bad: Of Shadow the Hedgehog. While the game tries to have some morality with the player's choices, Black Dooms remains as completely vile and the True Final Boss of the game. Word of God even states Shadow never followed him in the presumed canon true story (Pure Hero).
  • Bling of War: Wears several necklaces and chains.
  • Breath Weapon: Breathes fire as Devil Doom.
  • Colony Drop: Tosses meteors at you.
  • Cyclops: As Devil Doom.
  • Disney Villain Death: After being defeated in the Final Battle in the sky, he is sent falling several thousand feet to the ground below. If that didn't kill him, then Shadow blowing up the Black Comet seconds later probably did.
  • Doomy Dooms of Doom: His name.
  • Doppelgänger Attack: During his boss fights, he'll leave behind afterimages of himself that will perform one of his attacks.
  • Even Evil Has Loved Ones: Subverted. Despite his claims, he's not above using his own or needlessly sacrificing his people when it benefits him. It is especially zig-zagged with Shadow, as he communicates, and gets along well with him, but he had no problem with attempting to kill him for switching sides.
  • Evilutionary Biologist: Believes that humans' actions will only lead to their own extinction and that they serve a better purpose as food for the Black Arms.
  • Evil Sounds Deep: Almost Dr. Claw like.
  • Expy: He bears a resemblance to Wizeman with his similar attire, horns on his heads, detachable eyes, and being responsible for the protagonist's existence.
  • Frickin' Laser Beams: As Devil Doom, he has meteors surrounding him that fire lasers.
  • Galactic Conqueror: Claims to have conquered several worlds.
  • Go for the Eye: As Devil Doom, his weak spot is Doom's Eye.
  • Greater-Scope Villain: Retroactively for Adventure 2, as he supplied Gerald with the DNA to create Shadow and the Eclipse Cannon was originally designed to destroy his comet.
  • Guttural Growler: Since he looks like a devil, he's got a deep voice to match one.
  • Hoist by His Own Petard: Although Shadow's immunity to Black Doom's use of We Can Rule Together's derivations are unknown, it's heavily implied that the reason why Shadow was immune to Black Doom's gas is because he has Black Arms blood in him, more specifically the blood Black Doom gave to give birth to Shadow the Hedgehog.
  • Humans Are the Real Monsters: See Evilutionary Biologist.
  • Hypocrite: Despite talking about humans being evil, he needlessly sacrifices his army and doesn't show any regret.
  • I'm a Humanitarian: Oh dear God, yes. Though it's not Black Doom so much as the entire Black Arms race. And they don't seem to be content with just feasting on humans...
  • Jerkass: Very arrogant and cruel, going so far as sacrificing his own people in order to achieve his goals.
  • Killed Off for Real: Was singlehandedly killed by Super Shadow, along with the rest of his race when Shadow teleported the Black Comet back into space, right into the path of the Space Colony ARK's Eclipse Cannon.
  • King Koopa Copy: Let's see. Guttural Growler voices? Check. Evil alien overload? Check. Power-hungry tyrant? Check. Have a lot of power? Check. Manipulating the protagonists? Check. Despite how they do it on different approaches. Monstrous final bosses? Check. Red and black color schemes checks? Large and in charge? Check. Yep. Even Black Doom has some similar traits to King Koopa himself, despite being slightly more cold, ruthless, villainous, intelligent and devilish.
  • Knight of Cerebus: One of the few Sonic villains to be played completely seriously. His invasion of Earth is reminiscent of full-scale terrorism and he comes within a hairsbreadth of turning the human race into lunch. He also serves as a personal one to Shadow.
  • Kick the Dog: When he orders Shadow to get the Chaos Emeralds for him, he comes back with the exact thing that he wanted, and yet he still tells Shadow that he disobeyed him.
  • Knight Templar: Passes himself off as this, claiming that by feeding the humans to his larvae, he's offering salvation.
  • Like Father, Like Son: Black Doom seeks to conquer the world, Shadow ends up conquering the world in many of the bad endings.
  • Luke, I Am Your Father: His blood was used to create Shadow, and he sees Shadow as one of his own.
    Black Doom: I gave you life... and this is how you repay me?
  • Manipulative Bastard: He manipulates Shadow all through the game for him to help his cause, which includes make him remember Maria's death in detail, and make Shadow think that Humans Are the Real Monsters. Depending on the ending of the game, he succeeds and Shadow joins his cause, or Shadow ends up betraying him. He doesn't succeed in the canon ending.
    Black Doom: That's right. This will remind you of what the humans did to you. Never forget that horrifying image.
  • Mind over Matter: Devil Doom will telekinetically manipulate debris from the city below to form a shield around him.
  • Monster of the Week: He's a one-shot villain and the game's main adversary.
  • Multiple Head Case: Devil Doom has two heads on either side of his body, and Doom's Eye occasionally switches between them.
  • Mysterious Past: The Black Arms themselves don't get a lot of backstory, but events in the game imply they have wanted to take control of the Earth for thousands of years, even creating bases in the form of ancient temples. It wasn't until Gerald came along that their plan could actually succeed.
  • Names to Run Away from Really Fast: Black Doom. He might as well be named "Villain Von Bad Guy".
  • No Celebrities Were Harmed: You would be forgiven for believing that Doom was voiced by Frank Welker doing his Dr. Claw voice.
  • No Mouth: In his normal form. Subverted with Devil Doom.
  • One-Winged Angel: His "Devil Doom" form, a freakish, gargoyle-like monstrosity. Looks something like this.
  • Pet the Dog: Sharing humans as food with the other Black Arms is the closest thing he does to nice in the entire game.
  • Playing with Fire: He can toss flaming discs at you during his fights.
  • Power Floats: Justified, as he has no visible legs.
  • Rasputinian Death: Is blasted several dozen times in the eye with the Chaos Spear, plummets out of the sky and several thousand feet to the surface of the Black Comet, and if that didn't kill him, then the Black Comet being obliterated by the Eclipse Cannon definitely finished the job.
  • Really 700 Years Old: Has been around for 2000 years, and has visited the Earth many times.
  • Red and Black and Evil All Over: Just like Shadow. This is not a coincidence.
  • Red Eyes, Take Warning: He has a set of these and is the villain.
  • Satanic Archetype: Is black and red, has horns, tries to tempt Shadow to evil with varying degrees of success and is the Greater-Scope Villain of several disasters, and oh, his Super Form is a multiheaded dragon monster called Devil Doom who literally falls from the heavens upon defeat.
  • Sorcerous Overlord: The overlord of the aliens with some very strange powers to boot.
  • Starfish Aliens: Look at him!
  • Take Over the World: Claims to have conquered several worlds and wants to do the same to Earth.
  • Timed Mission: The final battle with him plays with this trope. As the fight between him and Shadow rages in the sky, Sonic and co. are slowly choking to death from the toxic gas of the Black Comet. The longer the fight goes on, the more bleak it becomes for them. However, you can take as long as you like and it won't affect the ending at all. Your only time limit is your ring count.
  • Third Eye: Doom's Eye, a tentacled monster that can move independently from Black Doom and can project holograms of himself. Black Doom can also speak through it.
  • This Cannot Be!: Is left in complete disbelief when he's finally defeated in the Golden Ending.
  • To Serve Man: Black Doom's ultimate goal. And he would have pulled it off if Shadow didn't turn out to be immune to his nerve gas and We Can Rule Together antics.
  • Villain Has a Point: Believes that humans' actions will only lead to their own extinction, and seeing the actions of certain individuals such as Gerald and his descendants, he is right to a certain degree.
  • Villain of the Week: His sole appearance is in Shadow the Hedgehog, and he's clearly the major threat of the game, with even Eggman being at his mercy near the end.
  • Voice of the Legion: He has this to go with Evil Sounds Deep.
  • We Can Rule Together: He pulls this a couple of times, though he's (arguably) really bad at it, and seems to honestly be surprised when Shadow says no.
  • Wings Do Nothing: Averted. As Devil Doom, he'll use his wings to defend against Shadow. Shadow can disable the wings to prevent this, but he'll still remain airborne.

Modern Era

    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 later 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: He is bald, and is completely insane, wanting to destroy the world instead of conquering it, or turn it into a card for his collection. He doesn't even seem to care about dying along with it.
  • Big Bad: Of the Sonic Rivals games.
  • Big Bad Duumvirate: With Eggman in the Rush 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 the Old Man 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.
  • Evil Genius: And even has the benefit of 200 years of technological advancement over Eggman.
  • Eviler Than Thou: He's Eggman without any redeeming qualities. While Eggman wants to rule the world, Nega is perfectly content with destroying it.
  • Evil Old Folks: Probably. He has a gray mustache.
  • Evil 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: Like his ancestor, Nega wears a pair of Kamina-like glasses with him, but is completely devoid of empathy, just wishing to see the world burn.
  • 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 disguising as him.
  • 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.
  • 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: Unlike the lovable and goofy Eggman, who despite being evil, has shown to have some sort of heart, Nega is completely devoid of empathy and his dream is to turn the world into a playground of destruction.
  • Sore Loser: Unlike Eggman, who takes his defeats gracefully in comparison, if Eggman Nega goes down, he tries to take the entire world with him.
  • To Create a Playground for Evil: His motivation, shown in the quote above.
  • Viler New Villain: Intended to be what Eggman would be like without his redeeming qualities. While Eggman'll pull an Enemy Mine so the world doesn't get destroyed, Eggman Nega is Ax-Crazy and wants mass-destruction in his plots(if destruction isn't his flat-out goal). He lacks any Affably Evil or Pet the Dog traits, and any "nice" qualities Nega shows are a facade.
  • 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.
  • 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 Hair, Black Heart: Played With. He is bald, but his mustache is white. He is also a complete utter psychopath.
  • You Have Outlived Your Usefulness: In Rush Adventure, he taunts Blaze by telling her that it was her family that enabled him to obtain the Jeweled Scepter, as they safeguarded it for generations, and now that he no longer needs them, he can easily use his new power to destroy them along with their entire kingdom.

    Babylon Rogues

Jet: "No way I'm gonna lose!"
Wave: "Unless I take charge, nothing ever gets done here!"
Storm: "I'll make sure to pay you back for this!"

Jet Voiced by: Daisuke Kishio (Japanese), Jason Griffith (English, 2005-2010), Michael Yurchak (English, 2010-present)
Wave Voiced by: Chie Nakamura (Japanese), Bella Hudson (English, 2005-2010), Kate Higgins (English, 2010-present)
Storm Voiced by: Kenji Nomura (Japanese), Dan Green (English, 2005-2010), Travis Willingham (English, 2010-present)

A group of extreme gear riding birds from the Sonic Riders series of games. Each member functions as The Rival to a member of "Team Sonic". The Bablylon rogues are descended from the ancient Babylonian civilization. Consists of Jet the Hawk, who is obsessed with being the best at extreme gear riding; Wave the Swallow, a Wrench Wench that maintains their extreme gears; and Storm the Albatross, who acts as the Dumb Muscle.

  • Adorkable: Storm when his tough-guy image begins to crack.
  • Amazing Technicolor Wildlife: Par for the course in a Sonic game, but special mention goes to Storm (who averts this and is colored exactly how a real albatross would be colored) and Wave (who actually justifies this trope by virtue of there being a real-life swallow with iridescent purple plumage).
  • Arrogant Kung-Fu Guy: Jet.
  • Annoying Laugh: Jet and Wave both have these.
  • Badass Biker: In Zero Gravity, Storm's Babylon Standard Type-S can transform into an air-bike for extra power and durability. As a Power Type character, he also has a natural affinity for the heavier Bike and Wheel type gears.
  • Bare Your Midriff: Wave.
  • Big, Thin, Short Trio: Storm is the big, Wave is the thin, and Jet is the short.
  • Bird People: All three are humanoid birds.
  • Black Eyes of Crazy: Sorta. For a while, it was believed that Storm had black sclera due to his artwork from the first game clearly depicting him with such. Turns out, the "sclera" are markings around his normal blue eyes.
  • Blow You Away: Jet can use his Paper Fan of Doom to stir up wind currents to disorient other riders.
  • Bruiser with a Soft Center: Granted, Storm's tough guy image fades rather quickly under the right circumstances. He acts flustered around girls and is shown to feel bad whenever he hurts someone he wasn't aiming for.
  • The Brute: Storm.
  • The Bully: All of them count to a certain degree, but Wave especially counts considering how she initially treats Tails.
  • Captain Crash: Storm has trouble landing with his gear. Interesting, this may be a reference to real life albatrosses, who really do have trouble landing, due to how massive their wings are compared to their comparatively compact bodies.
  • Carpet of Virility: Jet and Storm both have white feathers on their chests, Storm much more so than Jet. Wave, being a female, lacks this and wears a shirt instead.
  • Cast Herd: Like the Chaotix, they are rarely seen apart.
  • Chuck Cunningham Syndrome: Storm hasn't been seen since Sonic Free Riders.
  • Comic Trio: Jet is The Leader, of the headstrong variety. Storm is The Fool, blindly following Jet's orders, and Wave is the Only Sane Woman, viewing Jet as "unreliable", and often getting frustrated with his stubbornness and Storm's stupidity.
  • Crouching Moron, Hidden Badass: Storm may be a bit thick and have all the grace of a train wreck, but when he's given a mission, he usually gets great results.
  • The Dark Chick: Wave.
  • Determinator: Storm. When Amy ended up grabbing the Arc of the Cosmos that Jet was after, he ended up chasing Amy all the way from Meteor Tech to Aquatic Capitol. It was only after Amy knocked him on his ass that he calmed down enough to figure out where he was and once he got what he was after, he was gone in a flash to bring it back to Jet.
  • Don't You Dare Pity Me!: Jet hates being pitied. He nearly gave up the key to the Babylonian Treasure (treasure he was certain would leave him rolling in dough) back to Sonic simply because Sonic gave it back despite being the one to get it back from Eggman.
  • Dumb Muscle: Storm, again.
  • Dual Wielding: Jet's Paper Fans Of Doom when fully powered up.
  • Enfant Terrible: Jet is only 14 years old, making him a year younger than Sonic, and the youngest member of his team.
  • Everyone Has Standards: Well Jet does, anyways. Despite his arrogance and failure to take a loss, Jet is genuinely above cheating and would much rather win fairly. Of course, he's willing to bend his morals if he feels what's on the line is worth it, though he'll angrily back out if his opponent tries to hand it to him anyways. He also has pretty humble feelings about his place as a thief, admitting he has no interest in advanced technology or world domination (at least until Wave tells him they could sell it for a lot of money).
  • Expy: Wave's bandana, short tank top and massive wrench as a weapon of choice really invoke some Winry Rockbell vibes. Even her dynamic with Jet feels like a platonic version of Ed and Winry's relationship at times.
  • Feather Fingers: Taken to the logical extreme — their wings are so hand-like that they barely even qualify as wings anymore. They can even wear gloves on them!
  • Feathered Fiend: They're villainous anthropomorphic birds.
  • Freudian Trio:
    • Id: Storm.
    • Superego: Wave.
    • Ego: (with Id traits) Jet.
  • The Friend Nobody Likes: Storm often gets this treatment from Jet and Wave due to being an oaf.
  • Foolish Sibling, Responsible Sibling: Due to the fact that Wave views Jet as an unreliable little brother, Jet and Wave follow this trope. Wave is the responsible to Jet's foolish while Jet is the foolish to Wave's responsible.
  • Gadgeteer Genius: Wave.
  • Generation Xerox: Jet's father was the leader of the previous generation of Babylon Rogues, and Wave's father was their mechanic.
  • Gravity Master: Jet's gravity control in Sonic Riders: Zero Gravity thanks to the Ark of the Cosmos.
  • Greed: All of them, but Jet tends to stand out. He even snaps at Wave for interrupting a daydream he was having about money.
  • Hair-Trigger Temper: Jet.
  • Inferiority Superiority Complex: Implied with Wave in "Sonic Riders." In the story mode for the Babylon Rogues, while she insults Tails' hover board, she actually thinks (in her mind) that it wasn't so bad (also, in her bio, it states that she usually doesn't like admitting that someone has talent).
  • Informed Ability: Whether or not the Rogues can fly without their extreme Gear is... unclear. It's unlikely that they can, though, as they (apparently) don't have wings. Curiously, Wave is listed as a "Fly" character, like Tails, Rouge and Cream, so at the very least she must have some flight capabilities.
  • Informed Flaw: Storm is portrayed as being excessively clumsy and the worst of the three at handling extreme Gears. Within gameplay however, he can be just as nimble and graceful on a gear as anyone else.
  • Informed Species: Storm looks more like an owl than an albatross.
  • Intergenerational Friendship: Jet is 14, while Wave and Storm are 18 and 19.
  • Insufferable Genius: Wave. She takes her pride as the team mechanic seriously and refuses to accept any losses might be the result of her work.
  • It's All About Me: All of them, but especially Jet.
  • Jerkasses: Jet and Wave are not pleasant at all. In fact, they're the only ones of the current Anthro-cast to not have any redeeming qualities. Storm also counts to a lesser extent, as he is slightly more sympathetic (if only because he's more of a blind follower), but still pretty rude.
  • Jerk with a Heart of Gold: Jet doesn't mind going home empty-handed in Free Riders, because he had fun racing.
    Wave: Ugh, what a rip! Going home empty-handed is going to kill our rep as rogues.
    Storm: I'm real sorry about this, boss.
    Jet: Why? I actually had a pretty good time, at the end of the day!
  • Jerk Jock: Jet mocks newer competitors, thinks his surfing skills make him superior to everyone else, and is an asshole winner, yet a Sore Loser at the same time. He never respects anyone unless he approves of them.
  • The Klutz: Storm. This might be a reference to real albatrosses — their wings are simply so huge compared to their compact bodies and short stubby legs that it inevitably leads to some rough landings.
  • The Leader: Jet is Type III.
  • Like Brother and Sister: According to her profile on Sonic Channel, Wave views Jet as an "unreliable younger brother", but respects his role as leader.
  • Make Me Wanna Shout: Wave's yelling attack in the first Sonic Riders.
  • Manchild: At 19, Storm is the oldest of the three, yet he's also the most simple-minded and immature. However, Jet is also a petty jerk who whines at losing.
  • Mighty Glacier: Storm.
  • Moveset Clone: Each Rogue has the exact same stats as their Sonic trio counterparts.
  • Mr. Fixit: Wave does all of the maintenance of the Extreme Gear.
  • Multicolored Hair: Their "hair" is a lot more colorful than those of the other anthropomorphic characters; probably justified as they're birds and can get away with having such vibrant plumage.
  • The Napoleon: Jet.
  • Nice Mean And Inbetween: Despite Storm being pretty rude, it's clear that he defaults to being the nice one of the Babylon Rogues due to him being the most sympathetic one in the trio, whereas Jet is the mean one due to him being a trademark immature Jerkass. Wave sticks to the middle, being the in-between one, combining her snobbish personality and her sanity.
  • Ninja Pirate Zombie Robot: As of Sonic Riders: Zero Gravity, they found out they were humanoid bird genies from space.
  • Noble Demon: They may be a bunch of arrogant bullies, but they do have some redeeming qualities. Free Riders shows Jet refuses to cheat and would prefer to rely on his own skills to win, Wave does admit Tails isn't a bad inventor (to herself at least), and Storm has nothing but love and loyalty for the other two despite how bad they treat him. In fact, if it wasn't for their egos, they wouldn't be that bad at all.
  • Noblewoman's Laugh: Take a good look at Wave's victory animation when you finish a race on a standard board in Sonic Riders: Zero Gravity.
  • Nominal Hero: For a given value of "hero". While they are thieves and have a rivalry against Team Hero, they aren't outright evil and have had beef with Eggman as well.
  • Non-Standard Character Design: It's especially noticeable on Jet's concept art; the Rogues all seem to have larger hands than most Sonic characters. This may be due to them being birds and thus, their hands double as wings.
  • Older Sidekick: Wave and Storm to Jet.
  • Only Sane Man: Jet will take this role when Wave is too busy arguing and sniping at Storm, often angrily yelling at them to get it together.
  • Only Sane Woman: Wave is this in the group, since she's the one who constantly reminds Jet and Storm of their responsibilities. Granted, she can fall right into their antics too, especially with her arguments with Storm.
  • Pantsless Males, Fully-Dressed Females: In Sonic series fashion, Jet and Storm are both completely nude, save for their shoes and gloves, while Wave wears pants and a shirt.
  • Paper Fan of Doom: Jet uses these to attack other riders.
  • Promoted to Playable: After being a boss in the past few installments, Jet finally becomes a playable character in Mario & Sonic at the Rio 2016 Olympic Games with Wave coming along for the ride.
  • Power Crutch: Jet can only be considered Sonic's rival because of Extreme Gear. Without it, he's probably nowhere near as fast.
  • The Psycho Rangers: They are counterparts to the Main Trio; they have even more parallels to them than Team Dark.
    • Sonic and Jet are both the leaders of their respective teams, and both are speedsters with huge egos. However, while Sonic is generally a nice guy despite his ego, Jet is usually a Jerkass. As a bonus, Jet's color scheme is the opposite of Sonic's (green with blue eyes as opposed to Sonic's blue with green eyes).
    • Knuckles and Storm are both the muscle of their respective teams. Both are easily angered, and lacking in intelligence.
    • Tails and Wave are the odd ones out, with the only similarity they share being the fact that they're mechanics.
  • Quirky Mini Boss Squad: They're essentially a Jerkass version of Team Sonic.
  • The Rival: Jet to Sonic, Wave to Tails, and Storm to Knuckles. Jet definitely takes it the farthest, though.
  • Rivals Team Up: With Sonic.
  • Rouge Angles of Satin: A common victim.
  • Shadow Archetype: To the protagonist trio as a whole.
    • Jet to Sonic. They both live a free life, but Jet is a self-absorbed, petty jerk, who only cares about winning.
    • Wave to Tails. They both tend to be the smart one of their group, but Wave completely lacks the humble attitude of Tails, and is very nasty and selfish.
    • Storm to Knuckles. They're both the strong ones of their group, are extremely loyal, somewhat hot-heads, and tend to be a bit shy around girls (which somewhat expose their tough image), but Storm is rather rude, insensitive, and obnoxious, and hangs with the wrong crowd.
  • Satellite Character: Wave and Storm to Jet.
  • Shrinking Violet: Storm gets very nervous around most girls.
  • Sky Surfing: The bread and butter for all three of them. While Jet is the one who makes the most deal out of it, Wave seems to be the one who can do it the easiest, being the token Flight type of their trio. In Zero Gravity, her Babylon Standard Type-W is even capable of transforming into a body board-style Air Rider gear to allow her better control in the air.
  • Small Name, Big Ego: All of them, especially Jet and Wave.
  • The Smart Girl: Wave.
  • Smug Snake: Jet (and to some extent the other Rogues), in their more antagonistic bouts, are very overconfident jerks, despite their occasionally blundering nature.
  • Speech Impediment: Storm stutters when he's flustered.
  • Strong Family Resemblance: In his office, Jet has a picture of a hawk who looks very much like him, except wearing a cape and admiral's hat. Said hawk is likely Jet's father, who is said to be the leader of the previous generation of Babylon Rogues.
  • Super Strength: Storm in spades, capable of punching out cars and trains along the track, and stunning other riders with a clap of his hands.
  • Surrounded by Idiots: Wave has this perception sometimes. It doesn't help that in her official bio, she strongly hates stupid or thick-headed people, which explains her inhospitable attitude towards Storm.
  • Sore Loser: For someone who acts all high and mighty with a large superiority complex to make it worse, Jet can't stand losing.
  • Team Mom: Wave, much to Jet's chagrin.
  • Teen Genius: Wave.
  • Terrible Trio: At first.
  • The Bus Came Back: After being absent since Free Riders, Wave makes a return in Mario & Sonic at the Rio 2016 Olympic Games.
  • ¡Three Amigos!: A villainous example at first.
  • Token Evil Teammate: Not "evil", but Wave is the only member of the team who cheats. She was the one who booby-trapped Sonic's gear in the original Riders, after all. In Team Babylon's story in Free Riders, it's strongly implied that Wave tampered with Sonic's gear to guarantee that Jet would win, despite Jet telling her not to do so. Feeling that his win was illegitimate, Jet demands a rematch with Sonic, so they can race fair and square.
  • Tomboy with a Girly Streak: Wave is a tech genius with brash personality, but she also wears makeup and has very feminine pink-purple-lavender color scheme.
  • Throw Down the Bomblet: Wave can toss sticks of dynamite at other riders.
  • Two Guys and a Girl Jet and Storm are male, Wave is female.
  • Undying Loyalty: Storm is extremely loyal to Jet, and always follows his orders without question. His official profile even lists Jet as one of his favorite things, next to treasure.
  • Verbal Tic: Storm's "-waina" in the Japanese version.
  • Vocal Evolution: Jason Griffith's Jet in Zero Gravity is a lot deeper than in the first game.
  • Wings Do Nothing: Despite being birds, they don't even have wings, unless their arms double as wings (kind of like Daffy Duck).
  • With Friends Like These...: Wave and Storm argue quite a lot. Jet acts seemingly like this towards the former two.
  • With Catlike Tread: In the first Riders, Jet assigns Storm to espionage duty at one of Eggman's factories in order to dig up some dirt on Eggman. The following race involves Storm having to outrun Eggman's securty robots, destroying everything in his wake.
  • Wrench Wench: Wave (she even uses a giant wrench to attack).

    Mephiles the Dark & Iblis
Mephiles and Iblis at the moment of their creation.
The two components that make up the being known as Solaris. Mephiles represents its intelligence, and Iblis, its raw power. Some time 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.
  • Complete Immortality: Both Iblis and Mephiles have shown the ability to withstand considerable damage and regenerate. This, alongside the fact they don't seem to age, implies that they are immortal.
  • 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.
  • Metaphorically True: He tells Silver that Sonic is the Iblis trigger, and therefore the cause of Silver's current Bad Future. After being warped back in time by Mephiles, Silver tries to kill Sonic to prevent his Bad Future from ever occurring. However, it is Sonic's death that is the event that causes Iblis' awakening in the first place.
  • Red Oni, Blue Oni: Iblis simply destroys everything in its wake with no rhyme or reason and its primary color is red. Mephiles, while possessing formidable abilities himself, is the more manipulative and cooler-headed one of the two.
  • Ret Gone: Thanks to Elise blowing out the flame that is Solaris, they are erased from existence, although Crisis City still exists with Iblis's minions running around according to Sonic Generations, so it's possible Iblis still exists, and Mephiles reappeared as a playable character in Sonic Runners. In addition, Ian Flynn, the current writer of the official comic book, stated that Sega of Japan implied Mephiles became the Time Eater in the current timeline.
  • Villain of the Week: Yet another one-shot villain who upstages Eggman as the greater threat of a Sonic game.

"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 only interacted in one game, he was a pretty personal foe to Shadow, more so than any other character in the game.
  • Ax-Crazy: Let's see, his plans essentially amount to the destruction of existence 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.
  • The Bad Guy Wins: He actually succeeds in his plan to destroy the planet, and also heavily damaged the time-space continuum, 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.
  • Big "NO!": In the brief cinematic in which Solaris's core is destroyed, a faint "NOOOOOOOOOO!!!" in Mephiles's voice can be heard in the background audio.
  • The Bus Came Back: Mephiles reappears as an unlockable playable character in Sonic Runners, somehow.
  • 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. He seems to take note of this in the Final Story when he simply opts to just kill Sonic directly to cause Elise to cry.
  • Dark Is Evil: Just look at his name; Mephiles the Dark.
  • Dirty Coward: He usually fights 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 Counterpart: He's basically a malicious version of Shadow.
  • Evil Laugh: He lets out a good one when he kills Sonic.
  • Evil Twin: To Shadow.
  • Faux Affably Evil: He has a particularly eloquent way of speaking, seemingly offers a way for Silver and Blaze to save the future, and bows to Shadow and thanks him for his form. When push comes to shove, however, he's a vicious and manipulative coward who is quick to stop with the false compliments when somebody catches onto him.
  • 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 noticeable 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.
  • Fusion Dance: Combines with Iblis to become Solaris.
  • Hellish Pupils: His sclerae are red.
  • Hero Killer: He killed Sonic, but unfortunately for him, it didn't stick.
  • It Only Works Once: Shadow was able to seal his spectral form inside the Scepter of Darkness, but after taking on a more corporeal form by merging with Shadow's... shadow... in the present, he grows powerful enough to simply shatter the Scepter when Shadow tries to put him back in it.
    Mephiles: The "I" of now absorbed your shadow in the past. What may have worked ten years ago no longer does!
  • Jerkass: In case being a mean, deadly, and evil villain isn't enough, he also turns friends against each other, pretends he's helping people when he's manipulating them to get what he wants, and killed Sonic just to make Elise cry, then laughed at her crying.
  • Kick the Dog: He killed Sonic just to see Elise cry, and when she cried, he laughed in a sadistic manner.
  • Knight of Cerebus: Prior villains were either somewhat comical, or had some justification behind their motives. Mephiles possessed neither 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.
  • Leitmotif: "Mephiles' Whisper", an eerie piano theme that transitions to much louder instruments.
  • Literal Split Personality: Both Mephiles and Iblis. Mephiles being the conscious mind, and Iblis being the raw power of Solaris.
  • 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 cause 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 but 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.
  • New Powers as the Plot Demands: In the Last Story, he shows the power to bring every Chaos Emerald right to him as soon as he gets one, a power that is extremely useful in the Sonic games, with no prior reference or reason for this power to have appeared. Unfortunately, it's one of many parts of the issues that make people believe he has an extremely large case of Complexity Addiction, since in the future, he didn't show this power at all, and he gave a Chaos Emerald to Silver to start off the plot by way of Time Travel.
  • No Mouth: His muzzle kind of inflates and deflates when he talks, though.
  • Non-Standard Character Design: His crystalline form he uses for half the game is much more detailed than any of the other anthropomorphic characters, and lacks feet. Even in his (very rare) other appearances, the amount of detail stays.
  • 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. Both have planet-sized egos. 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.
  • Not-So-Well-Intentioned Extremist: He sent Silver to the past, not to help Silver stop Iblis from destroying the world, but to break Iblis's seal so that Mephiles and Iblis can reform into Solaris and consume all of time and existence.
  • 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 crystalline version of himself as pictured above.


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.

  • Almighty Idiot: He has no other motive than to destroy everything in existence. This is justified as he is the raw power of Solaris, and has no mind to control him.
  • Ax-Crazy: Even more so than Mephiles.
  • Demonic Possession: Averted. Despite being sealed inside of Elise's and later, Blaze's soul, Iblis makes no effort to take control of them. That is, assuming the cause of Crisis City's existence in Sonic Generations wasn't an attempt to take control of Blaze.
  • Eldritch Abomination: Both as himself and as part of Solaris.
  • Evil Is Burning Hot: He literally set the entire world on fire in the future.
  • Flat Character: Justified in that he's a mindless force of nature as opposed to an actual villain.
  • Fusion Dance: With Mephiles to become Solaris.
  • Go for the Eye: In its second and third forms.
  • King Koopa Copy: Iblis is a reptilian monster made out of lava. He has fire powers and is very powerful, destructive and has green eyes and flame red skin. Not to mention he is evil in nature and is the final boss in Silver's story.
  • Lava Adds Awesome: Not to Silver and Blaze, anyway.
  • Literal Split Personality: See Mephiles.
  • Living Lava: Originally a living flame, Iblis is a monster made out of lava, and is the source of both the smaller lava monsters and the lava-like wasteland of the Bad Future.
  • Mad God: Again, Solaris, although it's "mad" as in "rage" and not "mad" as in "insanity."
  • Magma Man: His body is made of the stuff.
  • Meaningful Name: In Islam, Iblis was a djinn who refused to bow to Adam despite God's command, and was cast out. He then becomes A'Shaytan, or Satan. In other words, like Mephiles, his name references the Devil himself.
  • Not Quite Dead: Possibly implied in Sonic Generations, as Crisis City still exists with Iblis's minions running around and Blaze states that Crisis City was her fault, possibly suggesting that Iblis still is or was sealed in Blaze, and given how Blaze's memory remained unchanged, it's possible her experience remained unchanged.
  • Playing with Fire: A given, being made of lava.
  • Sealed Inside a Person-Shaped Can: He was sealed inside of Elise. At the end of Silver's story, he's sealed inside of Blaze, but this doesn't stop Mephiles from merging with the present one inside of Elise.

Click here to see Solaris' second form 

A godlike being of light and time, revered by the people of Soleanna as a deity. However, experimentation on Solaris resulted in the being splitting into two halves — Mephiles and Iblis. Despite the heroes' best efforts to stave off the rebirth of Solaris, the inevitable happens.

  • Attack Its Weak Point: Its consciousness, represented by a fiery orb, is its main weak point.
  • Ax-Crazy: Remember how psychopathic and insane Mephiles is? Solaris is like that, too, given that Mephiles is Solaris' mind.
  • Beam Spam: Loves firing lots of laser beams, especially once it Turns Red. Oh, and these lasers are strong enough to injure Super Sonic, Super Shadow, and Super Silver.
  • Eldritch Abomination: It is a godlike monstrosity that can destroy timelines and dimensions at a whim.
  • Final Boss: Of Sonic the Hedgehog (2006).
  • Fusion Dance: Solaris' rebirth is from the combination of Mephiles and Iblis.
  • Killed Off for Real: By manner of Reset Button Ending.
  • Light Is Not Good: A being of heavenly light who is capable of destroying time itself.
  • Mad God: Though like Chaos, it's more due to rage than outright insanity.
  • Motif Merger: Mephiles has a sinister-sounding piano Leitmotif (with a techno remix as his boss fight music). Iblis is accompanied by a bombastic, orchestral score. When the two fuse together to form the True Final Boss Solaris, the phase 1 boss music is Mephiles' leitmotif, performed by Iblis' bombastic orchestra. Here are possible readable lyrics.
  • One-Winged Angel: After Solaris is defeated, it comes back for more in an angelic form.
  • Physical God: An incredibly otherworldly one, but still has somewhat of a physical form.
    • It's the first final boss fought in a Super form (outside of the Sonic Advance Trilogy and Sonic Rush Series) to be able to knock rings out of a Super character. Let us repeat, it can actually hurt Super Sonic, Super Shadow, and Super Silver. To contrast this, Perfect Chaos, Finalhazard, Metal Overlord, and Devil Doom were only able to slow them down.
  • Reality Warper: Creates a new, fragmented world just so it can use it to destroy time.
  • Ret Gone: After being defeated, Elise blows out the Flames of Disaster, thereby erasing Solaris from existence.
  • Shows Damage: Solaris' first form's stony body flakes off when taking damage.
  • Spacetime Eater: Easily capable of devouring entire dimensions and timelines.
  • The Voiceless: Doesn't say a word.

"You filthy rat! I'll shut that mouth of yours permanently!"

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.
    "I am... the Creator... The stories of this world are... mine!"
  • 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-Wayla, his sword has now become his tail.
  • Black Eyes of Evil: Black sclerae with red pupils to be exact.
  • Body Horror: His transformation was both unsettling and painful, to say the least.
  • The Bus Came Back: Returned as a "buddy" character in Sonic Runners. He (or rather, several voiceless clones of him) also appeared as a minor Arc Villain during an event in the same game.
  • 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 retrieve the Sacred Rings. Guess how he dies?
  • Domestic Abuser: Heavily implied 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 whose 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.
  • Eldritch Abomination: In his true form.
  • Expy: 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 Z's Majin Buu.
  • Family-Unfriendly Death: Baked in lava.
  • Final Boss, New Dimension: The fight against Alf-Layla-wa-Layla takes place in a giant black void. Considering that at this point, all but the last few pages of the Arabian Nights have been sucked dry, this makes sense.
  • Freudian Excuse: It's mentioned that he's been abused in the past. Though said abuse was partly a punishment for crimes he committed, so it doesn't diminish his Hate Sink status.
  • Hate Sink: Erazor Djinn is a power hungry, unempathetic and purely self-serving douchebag who has nothing remotely sympathetic or likable going for him, and he acts extremely arrogant and haughty towards everyone around him. He treats Shahra like dirt and after her sacrifice, he has the gall to mock her as being weak. And to say nothing of how he puts Sonic's life on the line to further his own ends, and talks down to him and insults him as being a rat. You won't so much as shed a tear for him when Sonic seals him in the lamp forever and destroys it.
  • 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.
  • In Their Own Image: His ultimate goal, once he's acquired the World Rings, is to remake the world of the Arabian Nights in his image, and then move on to Sonic's world and repeat the process. He even states as such during the final boss.
    Erazor: I will remake this world and this reality in my own image!
  • Jackass Genie: Oh yeah.
  • Kick the Dog: Mocks Shahra as a mere Genie of the Ring after killing her.
  • Kick the Son of a Bitch: Sonic is more than willing to give him his just desserts — forcing him to grant wishes against his will to restore the Arabian Nights and revive Shahra, sealing him in his lamp again forever, and then destroying his lamp to finish him off once and for all — after all the hell Erazor put him, Shahra, and the Arabian Nights world through.
  • Lack of Empathy: Feels no regret when he accidentally 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.
  • Misanthrope Supreme: In the past, he was punished for his misdeeds and sealed away in his lamp, to be trapped until he granted the wishes of 1000 people. When his sentence was finished, rather than mellow him out, all it did was renew Erazor's hatred for people.
  • Multi-Armed and Dangerous: Has six arms as Alf-Layla-wa-Layla.
  • One-Winged Angel: Alf-Layla-wa-Layla.
  • Opportunistic Bastard: Early on, he tries to shoot Shahra with a flaming arrow, but Sonic took the hit and was afflicted with a life-draining curse. Erazor uses it to his advantage, telling Sonic he'll remove the arrow and break the curse if Sonic gathers all of the World Rings for him.
  • 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 remaining pages of the book.
  • Playing with Fire: Ironic, considering his death.
  • Power Echoes: Alf Layla-wa-Layla's voice has a prominent echo effect.
  • Power Floats: Is never seen walking.
  • Power Makes Your Voice Deep: Inverted for Alf Layla-wa-Layla, who has a much higher-pitched voice than Erazor Djinn.
  • 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, though then the lamp is destroyed.
  • Slouch of Villainy: He's seen as this in the opening before shifting to an Ass-Kicking Pose for no stated reason.
  • The Sociopath: No Jackass Genie isn't one after all.
  • 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?!
  • Villain of the Week: Another one-shot villain who is the threat of a Sonic game instead of Eggman (who appears by proxy of King Shahryar, but isn't the villain at all).
  • Walking Shirtless Scene: Wears pants and a cape but no shirt.
  • We Can Rule Together: Offers this to Shahra.

    Captain Whisker

A robot pirate from the Sol Dimension.

    Dark Gaia
Click to see Dark Gaia's Perfect form. 

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

  • Alien Blood: Bright green.
  • Asteroids Monster: The dark creatures that plague the world at night? Those are pieces of its body.
  • Attack Its Weak Point: In its first form in both versions, Sonic must attack its green eyes. As Perfect Dark Gaia in the PS2/Wii version, Sonic must again attack its eyes.
  • Big-Bad Ensemble: With Dr. Eggman in Sonic Unleashed.
  • Body Horror: When it goes One-Winged Angel, four arms sprout out of its body, complete with Alien Blood. Its jaw splits open to reveal seven large green eyes and lots of tongues.
  • Casting a Shadow: When fully matured, it can shroud the earth in darkness.
  • Combat Tentacles: Large purple ones that can form a barrier around it and can impact targets with explosive force.
  • Complete Immortality: Much like Light Gaia, Dark Gaia can never die, as he is necessary for the planet's cycle of death and rebirth. Being defeated by Sonic will only render it dormant until it gains enough negative energy to destroy the earth.
  • Dark Is Evil: Just in the case the name wasn't enough of a giveaway.
  • Demonic Possession: The Dark Gaia monsters can possess others, instilling negative emotions in them.
  • Eldritch Abomination: Lives within the Earth and tries to bring its destruction, was born at the beginning of time, is the representation of night, darkness, and destruction, and is a colossal, immensely powerful monstrosity with a head-mouth full of eyes, teeth, and tongues. Then it goes One-Winged Angel and manages to become even more monstrous.
  • Evil Counterpart: Of Light Gaia, AKA Chip.
  • Evil Laugh: At several points during cutscenes and the fight itself, it makes vocalizations which sound a lot like raspy laughs.
  • Eye Beam: Can unleashing beams of energy from its eyes as Perfect Dark Gaia.
  • Eye Scream: Sonic inflicts this on him during the final battle and ultimately defeats it by charging straight into its center eye.
  • Eyes Do Not Belong There: It gains three green eyes on top of its head and has seven more inside its mouth.
  • Flat Character: Dark Gaia has no real motivation for its actions or characterization. Justified in that Dark Gaia is a mindless, malevolent force of nature as opposed to an actual plotting villain.
  • Final Boss: Of Sonic Unleashed.
  • Fisticuffs Boss: The PS2/Wii version is basically a boxing match between Dark Gaia and the Gaia Colossus.
  • Frickin' Laser Beams: Its Signature Move is to fire large beams of energy.
  • Go for the Eye: It's all that Sonic can do to take down Dark Gaia.
  • The Heartless: The Dark Gaia monsters are basically negative emotions given form by its dark energy.
  • Kaiju: The biggest opponent fought in the video game continuities, to the point its comparable to a mountain.
  • King Koopa Copy: It is a deadly, monstrous and notorious beast that is filled with power, hate, and death. Plus serves as the final boss in Sonic Unleashed.
  • Lovecraft Lite: Is a Lovecraftian Eldritch Abomination out to end the world, but Sonic can still kick its ass with assistance from Chip AKA Light Gaia, Dark Gaia's Good Counterpart.
  • More Teeth than the Osmond Family: Perfect Dark Gaia has a lot of huge teeth.
  • Multi-Armed and Dangerous: Has six arms as Perfect Dark Gaia.
  • One-Winged Angel: Perfect Dark Gaia, where it grows two more pairs of arms and opens its seven true eyes inside its mouth. In this state, it's capable of shrouding the world in its darkness in order to begin the process of wiping out all life on the planet.
  • Overly Long Tongue: Perfect Dark Gaia has two long, thin tongues on the sides of its big one.
  • Physical God: As an Elemental Embodiment of primordial darkness, night and negative emotions, it's hard to call it anything else. It also shares a rare role with Solaris in that its capable of knocking rings out of Super Sonic as Perfect Dark Gaia, and even with the Gaia Colossus backing him up Sonic is still forced to the point of exhaustion fighting it.
  • Press X to Not Die: Makes the player do this 60 times in its Perfect Dark Gaia form in the PS3/360 versions of Sonic Unleashed.
  • Purple Is the New Black: Dark Gaia's energy is shown as purple-colored.
  • Sealed Evil in a Can: Has been inside the Earth since the beginning of time and constantly undergoes a process of breaking free, destroying the world, and going back in once its done. Eggman opens the can prematurely at the beginning of the game (which is why it explodes into millions of pieces that scatter across the globe and become monsters), and it's back in the can by the end of the game.
  • Shoo Out the Clowns: Gives the equivalent of a Dope Slap to Eggman upon its revival in the Earth's core and knocks him clear out of the area to fight Sonic and Light Gaia (Chip).
  • Slasher Smile: Dark Gaia appears to sport one due to the eyes above its closed head-mouth.
  • Time Abyss: Has been around since the beginning of time.
  • Throat Light: As Dark Gaia.
  • Wave Motion Gun: Perfect Dark Gaia unleashes a giant laser beam from its eye in the PS3/360 version.

    Merlina the Wizard

"You could never understand my sorrow at seeing the ruinous future of this kingdom."

Voiced by: Mamiko Noto (Japanese), Melissa Hutchison (English)

A young sorceress from the world of ancient Camelot. She summons Sonic to her world to help stop King Arthur from terrorizing her kingdom. However, she has other intentions...

  • Anti-Villain: What seperates her from the other Sonic villains is that she is driven by purely altruistic motives. Merlina wants to make her world never end, by making it never change, so it won't end in warfare.
  • Batman Gambit: Her plan was to trick Sonic into defeating King Arthur so she could take the scabbard of Excalibur and use its immortality-granting powers to make the kingdom everlasting.
  • Big Bad: Of Sonic and the Black Knight.
  • Big Bad Friend: Merlina seems to be Sonic's ally early on, but is using him for her own means.
  • Casting a Shadow: As the Dark Queen.
  • The Chessmaster: Masterminded the plot of Sonic and the Black Knight.
  • Complete Immortality: She uses the Scabbard of Excalibur to grant this to her kingdom.
  • Curb-Stomp Battle: This is the nicest way you can describe her first fight with Sonic. No matter how hard he tries, he can't land a hit on her thanks to her barrier. Then she snaps Caliburn in half and basically beats the everloving snot out of him. If Sonic had not gotten his Heroic Second Wind, she would've killed him.
  • Dark Action Girl: Played with: she's an antagonist and the Final Boss, but is an Anti Villainess.
  • Defeat Means Friendship: Sonic manages to make her do a Heel–Face Turn by telling her to live each day to the fullest and cherish the time she and her kingdom have left.
  • Dual Wielding: Uses twin swords and twin Magic Staffs as the Dark Queen.
  • Energy Ball: Ultilizes these in her fight with Sonic.
  • Evil Albino: Her skin turns pale as the Dark Queen.
  • Multi-Armed and Dangerous: Her shadow can grow multiple arms to attack enemies.
  • One-Winged Angel: See Fusion Dance.
  • Some Kind of Force Field: Uses one to defend against Sonic during her boss fight and in the fight before that.
  • The Stoic: Always maintains a calm demeanor. Justified in that, in her view, she's doing what needs to be done to save her kingdom. Her emotional investment in this isn't much.
  • Straw Nihilist: She's a more sympathetic example than most. Merlina loves her world, but upon discovering that her world is doomed to end in ruin and warfare, became depressed and occasionally wondered why they should accomplish anything. Her solution was to try to find a way to make her world eternal.
    Merlina: Why do flowers bloom knowing they are destined to wither? Their time of beauty is so short-lived.
  • Supernatural Gold Eyes: As the Dark Queen.
  • Turns Red: More like turns black. As her health dwindles, her color scheme turns from blue to black.
  • Villain of the Week: A rare case where a new villain appears in place of Eggman, who is completely absent from the game.
  • Walking Spoiler: She's really the Big Bad throughout the entire game, despite her benevolent actions at first.
  • Well-Intentioned Extremist: Merlina wants to save her world... by stopping it from ever changing.
  • You Gotta Have Blue Hair: Her hair turns purple when she becomes the Dark Queen.

    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.

  • And I Must Scream: Does this to Sonic's friends, as they are Taken for Granite due to it, but implied to still be aware, judging by what Tails says upon his rescue.
    Tails: I thought I was dead! Floating without a body in a black limbo... *shivers* I'm gonna have nightmares for weeks.
  • Attack Its Weak Point: "Charge into the core!"
  • Big Bad: Of Sonic Generations, except it is revealed that Dr. Eggman and his past self are controlling it.
  • Casting a Shadow: Can fire dark energy blasts that immobilize opponents.
  • Clockwork Creature: The Time Eater is basically a mass of purple smoke with clock gears sticking out of it.
  • Detachment Combat: Its Warping Arm Attack sends its arms through time holes to attack unsuspecting opponents.
  • Eldritch Abomination: It is far more monstrous than any other creature ever battled by Sonic and has a bizarre set of powers, including the ability to tear through space-time itself. By the end of the game, it's still uncertain what the Time Eater even is or where it came from.
  • Final Boss, New Dimension: Sonic and his past self fight the Time Eater and both Eggmen in the Center of Time, where pieces of various stages featured throughout Sonic Generations float around.
  • Frickin' Laser Beams: Can fire small green laser beams in the 3DS version, as well as a large laser from its mouth in both versions.
  • "Get Back Here!" Boss: The fight with it in the console version mainly consists of the two Sonics chasing it through the center of time. Only Modern Sonic has to do so in the 3DS version, as Classic merely has to dodge its attacks until the core is exposed.
  • Good Wings, Evil Wings: Its perfected form has cybernetic wings.
  • Homing Projectile: Its main attack is this, which gets announced ad nauseum by your teammates.
    "That looks like a Homing Shot!"
  • Humongous Mecha: Turned into this so Dr. Eggman and his past self can control it to erase their past defeats at Sonic's hands.
  • Leitmotif: Has two versions, in Modern and Classic.
  • Living Shadow: Its initial appearance invokes this trope. As the plot progresses, its form takes shape and gets progressively more mechanical as a result of the Eggmen modifying it to fit their own ends.
  • Man Bites Man: Time Eater in the 3DS version will not hesitate to chomp on Modern Sonic after he manages to dodge all its other attacks.
  • Multi-Armed and Dangerous: The creature's final form has four arms, but only in the Console version. The 3DS one has a simplified design to comply with the handheld's limitations.
  • Playing with Fire: Its final, strongest attack in the console version is a massive fireball.
  • Power Floats: Justified in that it doesn't have legs.
  • Reality Warper: Done through destroying time and space. Eggman intends to exploit the creature's ability to damage the fabric of reality to erase his past failures and improve on his chances to defeat Sonic.
  • Super Strength: Able to easily knock out Sonic and his past self and nearly crush them, while holding back, with one arm. Fortunately, Sonic's friends cheering on both of them allows them to get up and defeat the Time Eater.
  • Suspiciously Similar Substitute: Shares multiple characteristics with Solaris from Sonic 06. Ian Flynn noticed this, and wondered if the Time Eater is what remains of Solaris after the Reset Button. So far, Sega hasn't given an answer.
  • Space Time Eater: Its name is Exactly What It Says on the Tin. By devouring the space-time continuum, the Time Eater damages the fabric of reality, leaving only the White Space.
  • Taken for Granite: The Time Eater kidnaps Sonic's friends and freezes time for them, turning them into blank statues in the White Space.
  • Time Master: Can manipulate time and space, either by slowing down the flow of time or erasing pieces of the timeline.
  • The Voiceless: It does grunt and growl sometimes, but is incapable of speech.

    Deadly Six
From left to right: Zazz, Zor, Zavok, Zomom, Zeena, Master Zik
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..."

Zomom Voiced by: Chafurin (Japanese), Patrick Seitz (English)
Zik Voiced by: Mugihito (Japanese), Kirk Thornton (English)
Zeena Voiced by: Yumi Touma (Japanese), Stephanie Sheh (English)
Zor Voiced by: Yuki Tai (Japanese), Sam Riegel (English)
Zazz Voiced by: Yutaka Aoyama (Japanese), Liam O'Brien (English)

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 it over themselves. They are composed of Zavok (Red), Zazz (Pink), Zeena (Green), (Master) Zik (Blue), Zomom (Orange), and Zor (Purple).

  • Bad Boss: Notably averted with Zavok. Though he does get frustrated with the gang at times, he never punishes them. It's especially shown when they accidentally 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 very comical. 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 personified. 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. So much so that his official profiles state he loves fighting more than eating three meals a day, and that holding him back from a fight will send him into a rage.
    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.
  • Breakout Villain: Zazz quickly started showing up in other games, while the other Zeti have been reduced to cameos or less. Zazz was added to Sonic Dash, as a boss, and was kept even after the Lost World promotional event ended. Then he had his own event in Sonic Runners. Most recently, he (and Zavok) have joined the playable cast of Mario & Sonic at the Rio 2016 Olympic Games, again, without any of the others. Zavok appears as a playable racer in Team Sonic Racing. Zavok also returns in Sonic Forces, having joined Eggman alongside Chaos, Metal Sonic, Shadow, and Infinite. Subverted in that the Zavok in Forces is revealed to be an illusion.
  • Breath Weapon: Zavok can fire beams and fireballs from his mouth during his final battle in Sonic Lost World.
  • 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 Characters: 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' 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.
  • Disney Villain Death: Zavok and Zor both get baked in lava. Though Zavok returned in Sonic Forces.
  • Disproportionate Retribution: Wanting revenge for being enslaved by Eggman? Understandable. Destroying the world and stealing its energy to do that? Overkill.
  • 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!
  • Dragon Rider: Zavok's boss fights involve him riding a robotic dragon. The boss fight with him in Forces has him riding a robotic wasp instead.
  • The Dragon: Unwilling ones to Eggman at the beginning of Sonic Lost World, kept in line by the Cacophonic Conch. Zavok reprises this role in Sonic Forces for reasons unknown. Subverted in that the Zavok in Forces is revealed to be an impostor.
  • Dragon Ascendant: Once Sonic kicks the conch away, they quickly hand Eggman their resignation.
  • 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. Zavok's return in Sonic Forces implies that they survived. Subverted in that the Zavok in Forces is revealed to be an illusion.
    • Subverted in the 3DS version. They merely fly away after their final battles.
  • Dub Name Change: Not to any of the six specifically, but rather to their race; they're referred to as the "Eggman Six Demon Clique" as a group and, in general species terms, flat-out Demons in the Japanese dialogue, which makes out the group to be sort of like monster guardians to the Lost Hex.
  • Dumb Muscle: Zomom, complete with Simpleton Voice.
  • The Eeyore: Zor, 'nuff said.
    Zor: Gotta go tell the others the bad news... 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 off 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 ruining her nails during their last fight.
  • Evil Knockoff: The Zavok shown in Forces is revealed to be a Virtual Reality construct created by Infinite with the power of the Phantom Ruby.
  • 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 that he's big. He won't react well to anyone else calling him fat, though...
  • Fat Bastard: Zomom, again.
  • Fingerless Gloves: Zor.
  • The Fighting Narcissist: Zeena, who is always seen painting her nails and values them above everything else.
  • Flat Character: They’re mostly one note characters who don’t get any character development.
  • 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.
  • Flunky Boss: The boss fight with Zavok in Forces has him summon smaller versions of his wasp mech.
  • 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.
  • Frickin' Laser Beams: The boss fight with Zavok in the 3DS version has him commanding his dragon mech to form rotating ring around him while firing red laser beams. His wasp mech in Forces can also fire lasers from its six legs.
  • 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.
  • Go-Karting with Bowser: Zavok and Zazz are playable in Mario & Sonic at the Rio 2016 Olympic Games.
  • Good Old Fisticuffs: Zavok mainly uses his fists in battle. This gets taken to its logical conclusion in the Rio 2016 Olympic Games where he serves as both the main opponent and a playable character in Boxing matches.
  • Goth: Zor, with his gloomy expression, white skin, comb-over 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.
  • Hidden Depths:
    • For all of his villainous tendencies, Zavok in the Rio 2016 Olympic Games is shown to be a Spirited Competitor and enjoys the chance to improve his skills.
    • Zazz in the Rio 2016 Olympic Games is shown to be surprisingly good at tennis.
    • Zomom has low self-esteem, wondering if it's possible to make him look worse, telling Sonic not to make fun of his size as it's hurtful, and upon being defeated for the last time, saying that his mother was right about him being a failure.
  • 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.
  • I'm a Humanitarian: Zomom expresses a desire to eat both Sonic and Eggman.
  • In a Single Bound: They are all capable of leaping incredible heights and distances. The 3DS version 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.
  • King Koopa Copy: Zavok has huge fangs, spiky shoulders, Evil Eyebrows, and menacing claws. He's also the leader and the strongest member of the Deadly Six. But despite being a mere henchman with a lanky physique, Zazz actually has even more in common. With his mohawk and spiky collar and bracelets, he bears an even stronger resemblance to Bowser. Also, he has a similar brutish personality, in contrast to Zavok's more calm, menacing attitude. Zavok's similarities escalate further in his final boss battle when he grows exponentially above a pit of lava and has fire breath. Ironically enough, both he and Bowser are characters in the Rio 2016 Olympic Games.
  • Knight of Cerebus: Yeah, 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.
  • 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 for the course when you're voiced by Travis Willingham.
  • Laughably Evil: Unlike many previous examples in the series, however, they're evidently quirky and try to make a laugh out of their antics. By Word of God, they were described as made to "bring a sense of danger and humor" to Sonic Lost World.
  • Lean and Mean: Zazz is the thinnest of the six.
  • Literal-Minded: Zomom, as part of his being the Dumb Muscle.
  • 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. The boss fight with him in Forces has an aggressive, techno remix of his theme from Lost World.
    • 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 befits 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.
  • Letter Motif: Their names and the name of their species all begin with "Z".
  • Lightning Bruiser: Zavok and Zomom stand out as the physically strongest of the Six and are much faster than their sizes imply.
  • Make My Monster Grow: Zavok's final fight with Sonic in Sonic Lost World has him growing to a giant size while chasing him up a tower.
  • Manipulative Bastard: Zavok knows exactly what to say to motivate Zeena. He does the same to Zazz in Sonic Runners; he knows very well that Zazz can't beat Sonic, no matter how hard he tries, but the data Zazz collects may one day allow them to defeat Sonic.
  • Me's a Crowd: Zor can make shadowy copies of himself.
  • Miniature Senior Citizens: Zik is the oldest and shortest member of the six.
  • Muscles Are Meaningless: Zazz's lanky physigue doesn't stop him from being able to lift, carry, and throw his Moon Mech like it's nothing.
  • 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.
  • No Name Given: Zavok and Zeena's names are never mentioned in-game by any of the characters in Sonic Lost World.
  • 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 Quite Dead: Appears to have been the case for Zavok and Zazz at least, considering they've made several return appearances in games like Mario & Sonic at the Olympic Games, Sonic Dash and Team Sonic Racing.
  • 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! In fact, they're ALL aged over 100. The former, however... appears to be 1,036 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 the world 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.
  • Pragmatic Villainy: Though he despises being enslaved by Eggman, Zavok still commits to the role for a while in order to learn more about Sonic since he knew full well that Sonic would end up opposing him whenever they broke free.
  • Prepare to Die:
    Zavok: Your fate is to be destroyed. Why don't you just accept that? Lie down and die!
  • Promoted to Playable: Zavok and Zazz are playable in the Olympic Games.
  • Punny Name: "Zavok" sounds similar to "havoc". Likewise, "Zazz" sounds similar to "Jazz".
  • 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 Sonic.
  • Quirky Miniboss Squad: With the slight subversion in that they become the Big Bads by World 2, but they never lose their quirkiness.
  • Proud Warrior Race Guy: Zavok prides himself as the strongest warrior of the Zeti race, and takes joy in competing against others and improving his skills.
  • Ragin' Cajun: Zazz sports a slight, but noticeable 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 millennium old).
  • Real Men Wear Pink: Zazz has magenta skin.
  • Recurring Boss: Each of the Deadly Six are fought three times throughout Sonic Lost World.
  • Recurring Element: A demonic monster who overthrows 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 and Black and Evil All Over: Zavok's primary color is red with elements of black, and he's the leader of the villainous Deadly Six.
  • 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.
  • 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.
  • 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, as well as Zavok's return in Sonic Forces.
  • Sexophone: Part of Zeena's Leitmotif.
  • 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 is the only female member of the group.
  • 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.
  • Tactical Suicide Boss: Zavok in Forces would be much harder to fight if he remained in midair throughout the fight, but he constantly tries to impale Sonic with the wasp mech's stinger, the force of the impact launching Sonic high enough into the air to land a Homing Attack.
  • Technopath: Through their innate ability to manipulate electromagnetic fields, they are able to control machines, including Eggman's robots.
  • Turns Red: After being reduced to half health during the boss fight in Forces, Zavok reduces the size of the platform Sonic is fighting on and starts using a Dash Attack with the stinger on his wasp mech.
  • Two Words: Added Emphasis: 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 in Sonic Lost World. 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: You're seriously still here? Why won't you just die?! Ugh! You're like a cockroach with a horrible fashion sense!
  • Worthy Opponent: Zavok would consider Sonic one if he wasn't such a nuisance.
  • 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.


You may call me... Infinite... in the brief moments that remain to you.

Voiced by: Takashi Kondo (Japanese), Liam O'Brien (English)

A mysterious villain who joins Eggman's bid for world conquest.

Originally a self-styled "Ultimate Mercenary" jackal hired by Eggman and leader of his own "Jackal Squad," a crushing defeat by Shadow led him to start wearing a mask and pursue power even greater than Shadow's Chaos abilities — which he believes he has now thanks to Eggman's Phantom Ruby.

  • Achilles' Heel:
    • The Phantom Ruby's illusions are powerful, but they can be countered by someone who has a Phantom Ruby as well, and being in close proximity to a Phantom Ruby weakens his own. The Avatar manages to find a Phantom Ruby prototype left behind by Infinite, allowing them to survive Infinite's illusion during their fight with him, and allowing them to ultimately foil Eggman's plan to destroy the Resistance with a virtual sun.
    • Infinite's character bears one perhaps even more noteworthy than the rare possibility of a second Phantom Ruby nullifying his powers: namely, his hopeless addiction to sadism. Infinite isn't interested in pragmatism; his personal agenda is domination, to relish in the fear, suffering, and subjugation of others as much as possible, constantly playing it off as it "not being worth the time" to finish off the enemy. Even after Eggman calls him out on letting Sonic live when he had him cornered, the one person who could absolutely ruin everything, Infinite tries to rationalize it away. Even beyond that, Infinite failed to recognize what he'd inadvertently created when he subjected the Avatar to the same experience that led to him becoming so powerful.
    • The Phantom Ruby can't function without an external power supply of some sort. If all power supplies are destroyed, Infinite would no longer have access to his greatest weapon and be substantially weakened. This one isn't fully exploited, as Eggman had a backup power supply when the primary one, the Death Egg, was destroyed.
  • Adjusting Your Glasses: Performs the "by the bridge" method to his mask.
  • Always Second Best:
    • Episode Shadow reveals that he was this to Shadow. He was the captain of a mercenary squad and touted himself as the "Ultimate Mercenary" until he was dealt a crushing defeat at the hands of the Ultimate Life Form. The humiliation drove Infinite to seek power so he'll never be weak again.
    • His seeming mastery of his powers granted by the Phantom Ruby makes it appear as though he's the only one who could use them. However, the prequel comics reveal that Eggman was the Ruby's original wielder — however brief — and he could utilize it with far greater ease, and when he takes it back at the game's climax, he immediately demonstrates a greater level of power in projections than Infinite ever had.
  • Always Someone Better: He has Sonic's number in hand-to-hand combat, able to defeat him effortlessly. Of course, as the game progresses, Sonic eventually returns the favor.
  • Ambiguous Situation:
    • The game reveals that the gem embedded into his chest is the Phantom Ruby, or rather, the finalized version of a prototype Phantom Ruby created by Eggman. What happened to the original and how Infinite is connected to said Ruby remains unknown... Unless you play Episode Shadow, wherein you learn that Infinite was the leader of the Jackal Squad Eggman hired to protect his base in Mystic Jungle, where the real Phantom Ruby was being analyzed.
    • It's also left vague on whether the Phantom Ruby's abilities are just illusions, outright reality warping, or a mix of the two. While the villains are revealed to be virtual reality constructs and the obstacles that appear during his boss fights are illusions manifested by the Ruby's power, Infinite's energy attacks and the Phantom Ruby's ability to distort gravity and create Null Space implies that there's more to the Ruby's power than what has been told.
  • Apocalypse How: He nearly pulls off a Class 6 when he tries to erase the resistance by dropping a construct of the sun onto them.
  • Arch-Enemy:
  • Artificial Person: Infinite is shown to be this in the opening, as Eggman's latest and most powerful experiment, though he most certainly wasn't always.
  • Asshole Victim: Shadow was cruel to him and his team... but they'd already put their lot in with Eggman to help take over the world and get power at that point.
  • Attack Drones: His red energy cubes serve as these for him, as his main fighting style is to send his cubes to attack opponents, arranging them in various shapes and formations.
  • Authority Equals Asskicking: He's The Leader of the Eggman Army, and by far and away its most powerful member.
  • Ax-Crazy: He hides it well, but it's pretty clear that Infinite is quite unhinged underneath it all, as he relishes in causing death and destruction. In the final issue of the tie-in comic, when Infinite strikes the Phantom Ruby with his sword, he's shown what he desires most: a desolate, destroyed world, implying that he was crazy even before he gained the Ruby's power.
  • Badass Armfold: His default pose.
  • Badass Baritone: Has a deep, commanding, echoing voice thanks to Liam O'Brien voicing him, and is clearly one of the powerhouses of Eggman's army.
  • Badass in Charge: Leads the Eggman Army in Sonic Forces and more than capable of kicking you all around.
  • Badass Normal: The final tie-in comic shows that before he gained the power of the Phantom Ruby, he was a highly skilled mercenary captain. He managed to fight his way through hundreds of Eggman's robots and came within a hairsbreadth of actually killing the good doctor, only failing due to the Phantom Ruby's interference.
  • Battle Aura: Gains one when using his powers, but how it looks depends on the version. In the PS4/XBOX One version, he glows with a red aura and is surrounded by a purple haze that occasionally flickers with red, glitching static. In the Switch version, he has a simple red outline. In the comics, his aura resembles crimson flames.
  • Berserk Button: He does not like being called "weak" very much.
  • Bragging Theme Tune: His theme is essentially just bragging about how dangerous and awesome he is.
  • Break the Haughty: Episode Shadow reveals that prior to the game, he was the captain of a mercenary team called Squad Jackal, and touted himself as the "Ultimate Mercenary". That all changed one fateful day when he and his squad were hired by Eggman to protect one of his laboratories in Mystic Jungle, where they encountered Shadow the Hedgehog. Shadow effortlessly destroyed his entire squad and handed Infinite a humiliating defeat, which would lead to Infinite's vow to become stronger and lead to him obtaining the power of the Phantom Ruby.
  • Bring It: Makes this gesture to Sonic at the beginning of their final battle, right before growing to giant size.
  • Bond Villain Stupidity: In his second fight with Sonic, despite still being more powerful than him, Infinite decides against killing him, deeming him not worth the effort. Eggman utterly blasts him for this, and indeed, it comes back to haunt him later as Sonic eventually becomes strong enough to defeat him.
  • Boss Remix: An instrumental version of his theme song plays during the first two boss fights with him.
  • The Bully: When you get right down to it, at his core, Infinite is nothing but a superpowered bully who enjoys flaunting his power and superiority over others. He constantly insults Sonic and his allies, hovers above his opponents so he can literally look down on them, and shows no respect for anyone. His backstory in Episode Shadow reveals that the reason he became Infinite in the first place was that he was handed a humiliating defeat by Shadow and wanted power so he'll never be weak again, much like how real-life bullies are often motivated by a need to feel powerful.
  • Character Tic: His mask appears to be very loose-fitting, as he has to frequently adjust it.
  • Characterization Marches On: In Episode Shadow, he was shown be more emotive and his speech was as rough as you'd expect from a mercenary. By the time of the main game, his personality has done a complete 180 and he's far more stoic and practically emotionless. Also, his speech is far more eloquent and theatrical.
  • Chekhov's Gun: During his fight with Silver, Infinite drops one of the Phantom Ruby prototypes he was supposed to destroy. The Avatar would later find that same prototype, allowing them to survive Infinite's illusion during their fight with him, and allowing them to ultimately foil Eggman's plan to destroy the Resistance with a virtual sun.
  • Cold Ham: Despite his calm demeanor and subdued voice, practically every line of dialog that comes out of him is an over the top Badass Boast.
  • Colony Drop: Eggman and Infinite's plan to destroy the Resistance? Use the Phantom Ruby to create a virtual reality construct of the Sun and drop it on them.
  • Colour-Coded Timestop: While not exactly a time-stop, his teleportation produces the same effect as the Phantom Ruby. This is not a coincidence.
  • Cool Sword: The final issue tie-in comic for Sonic Forces shows that Infinite's Weapon of Choice before gaining the power of the Phantom Ruby was a red sword curved like a scimitar.
  • Create Your Own Hero: Infinite himself would inevitability create someone who would oppose him — the future Rookie of the Resistance, who would go on to be the key player in stopping Infinite once and for all.
  • Create Your Own Villain: He was hired by Eggman to protect the facility the Phantom Ruby was being studied in — then Shadow rolled around and mercilessly crushed him. Infinite was so taken by terror and humiliation that he more or less sold his soul for the sake of power, giving himself over to Eggman to become the Ruby's testing grounds.
  • Cunning Like a Fox: His mask is modeled after a fox's head and he has a bushy tail like a fox, even though he's actually a jackal.
  • Curb-Stomp Battle: He's an undisputed master of this.
    • An unmasked Infinite is on the receiving end of this to Shadow in Eggman's Facility in Mystic Jungle, which would lead to his Start of Darkness and him becoming Infinite.
    • In Issue Three of the Sonic Forces prequel comic, Looming Shadow, Eggman dispatches Infinite to deal with Omega when he rampages through his Arsenal Pyramid as a test of his abilities. It's not a spoiler to say he won decisively.
    • His first meeting with Sonic has him and the other villains dealing out a brutal one to Sonic, with Infinite in particular not even using his hands. The Blue Blur is unable to fight back at all and is soundly defeated.
    • A flashback shows him dealing out one to the Avatar and his team, frightening the Avatar so much that they ran away in fear.
    • In Mystic Jungle, Silver tries to hold his own against Infinite. Key word is tries. It ended as well as you'd expect, and Silver would've been killed had Sonic not stepped in.
  • Cutscene Power to the Max: All those energy attacks Infinite uses? You won't see them in his boss fights. Possibly justified by his need to prove himself stronger, and thus holding back.
  • Cyborg: The heroes believe he was built by Eggman, but in actuality he seems to be this. If nothing else, he has Eggman's perfected artificial Phantom Ruby embedded in his chest and some sort of upgrades that increased his physical abilities.
  • Dark Is Evil: He's one of the villains and his predominant colors are black and white, with hints of red here and there. When his aura is active, his entire body, sans the gem on his chest, turns black.
  • Darth Vader Clone: He's got a scary mask with a voice to match, black coloration, powers that prominently include the color red, once wielded a red sword in the prequel comic, and is Eggman's most prominent second-in-command in Forces. On the other hand, his blatant emotional instability, which ultimately ends up undermining his own victories, resembles that of Kylo Ren.
  • Dash Attack: One of his attacks during the Avatar's boss fight with him has him dashing at the player like a rocket, similarly to Sonic's Homing Attack.
  • Deal with the Devil: Issue Four: Rise of Infinite reveals exactly who Infinite once was: he was the leader of a band of thieves before Eggman offered him and his band the chance to work for him, having been given a glimpse of Infinite's own secret desires and tempted him with the chance to see them realized.
  • Deconstructed Character Archetype: Of the Sadist and Darker and Edgier archetypes. Infinite is extremely dangerous, but his constant need to relish in the pain and suffering of others screws him and Eggman over on several occasions, such as letting Sonic live when he could have easily finished him off, or killing the Avatar's squadmates, an act that would inspire the Avatar to become stronger and ultimately be the one to foil Eggman's plan to incinerate the Resistance with a virtual sun. His motives also turn out to be due to him being little more than The Bully, reveling in pain to support his own wrecked confidence after Shadow handily beat him.
  • The Dragon: Is Eggman's right-hand man in Forces. The fourth comic that was released alongside the game reveals that Infinite's squad was raiding Eggman's base to make quick cash. Eggman offers Infinite the chance to help take over the world.
  • Dragon-in-Chief: Eggman probably couldn't have defeated Sonic and taken over most of the world without him. Though Infinite would be absolutely nothing more than a sellsword without Eggman giving him the power of the Phantom Ruby, so it really all evens out. Ultimately, in spite of Infinite's impudence towards Eggman heavily implying a betrayal, it is the doctor that ultimately dismisses him and takes the Phantom Ruby for himself after he fails too many times.
  • The Dreaded:
  • Driven by Envy: Everything he is today is a desperate attempt to one-up Shadow.
  • Driven to Madness: Overlapping a bit with Go Mad from the Revelation, when Infinite tries to avenge his squad's destruction at Shadow's hands, Shadow delivers an absolutely brutal No-Holds-Barred Beatdown, mocking him as he lies broken and trembling at Shadow's feet. The sheer terror this instilled in the mercenary positively broke him, and he became obsessed with obtaining power so that he would never be driven to that point again. Though it should be noted the vision he was given by the Phantom Ruby (a wrecked, desolate world) and that he completely willingly signed up with Eggman to take over the world implies he was somewhat insane to begin with and Shadow just made him more overtly so.
  • Drunk on the Dark Side: It's pretty clear he's drunk with power and loves lording it over everyone else and abusing it to no end. Though slightly unusually for this trope, he's more of a Cold Ham. Unfortunately for him, he's so caught up in his own power and believed superiority that he makes serious mistakes that screw him and Eggman over on multiple occasions.
  • Evil Counterpart: Episode Shadow pretty much makes him one to the Avatar. Both of them had their entire squads destroyed by a powerful enemy and were belittled and mocked, leading them to vow to become stronger. However, the Avatar wants to be stronger to protect the world and his/her friends, while Infinite seeks power for his own sake.
  • Evil Gloating: Constantly. Infinite just loves to talk on and on about how invincible he is to all his opponents. And, yes, while he can back it up, this trait likewise showcases how much his power blinds him to the potential danger that leaving his opponents alive poses in the moments they do overcome his power. By the time Sonic faces him for the third and final time, he indirectly tells him You Talk Too Much in their banter.
  • Eviler Than Thou: Asserts that he seems himself as this compared to Eggman. Eggman later reveals he had no intention of Infinite being his end goal and already had a replacement prepared from square one in the form of his final mecha. When Infinite fails one time too many, Eggman disposes of him and takes his place without a second thought.
  • Evil Is Petty: His motivation for wanting to destroy the world and seek power? Because Shadow defeated him and called him weak. There's also a part of For the Evulz in that as well due to his sadism.
  • Evil Laugh: Will do this occasionally, such as when you die during the boss fights with him.
  • Evil Tastes Good: Tying in with his sadism. During his first meeting with the Avatar, he reflects that he can "taste" his fear, anxiety, and doubt, and finds it "delicious."
  • Evil Sounds Deep: Has a deep, scary voice that contains a noticeable echo effect, though that's likely due to the Phantom Ruby, as his voice before he had his mask was less intimidating, but still pretty deep.
  • Evil Wears Black: Wears black gloves and boots and is one of the villains.
  • Exotic Eye Designs: The mask and Phantom Ruby give him a golden pupil with red sclera. When not wearing the mask, he has a blue eye and a yellow eye.
  • Extremity Extremist: In his first battle with Sonic, he manages to defeat him without even using his hands (save for using his energy blasts), literally kicking him around like a big blue ball.
  • Facial Horror: He has a patch of fur over his right eye that makes it look like he has a scar.
  • Failed a Spot Check: He dropped one of the Ruby prototypes and didn't notice it and the Avatar dropping that same Ruby later and Infinite not even seeing it right in the Avatar's hand.
  • Fatal Flaw:
  • Flash Step: He's quick enough to perform these.
  • Flight: He's capable of flying. Mostly because of the Phantom Ruby.
  • Flunky Boss: After damaging him enough during the Avatar's boss fight with him, Infinite will summon Eggman's robots to assist him.
  • Foil: Can be seen as one to Metal Sonic. Both are Eggman's most powerful creations and both of them have massive inferiority complexes against one of the main characters. But Metal Sonic is a robot designed to resemble Sonic, while Infinite was an ordinary Jackal who is empowered by the Phantom Ruby. Also, while Metal Sonic has double-crossed the doctor on more than one occasion, Infinite remains loyal to Eggman to the end.
  • From Nobody to Nightmare: Infinite wasn't born with his powers, back then he was just a jackal. Episode Shadow reveals that he was once a mercenary who joined Eggman after taking his offer to help take over the world and was assigned to protect his lab in Mystic Jungle, where he encountered Shadow. After a humiliating defeat at Shadow's hands, he vowed to become stronger, leading him to become Infinite.
  • Hate Sink: While he wasn't this when he was a Badass Normal, it ends up being what he is by the events of the game. A Psychopathic Manchild with a constant Sadist streak, he may appear to be a badass, but by the end, it's clear that he's nothing but a bully. He's not even competent enough to keep the fight up, removing what may have been his only redeeming quality: his cool factor.
  • Hand Blast: He is able to fire laser beams and Energy Balls from his hands.
  • The Heavy: He takes leadership of Eggman's army in Sonic Forces.
  • Hero Killer: Downplayed in that the only people he actually kills are the Avatar's teammates, but he effortlessly defeats other powerful characters such as Sonic, Silver, and Omega.
  • Hired Guns: He was a mercenary before Shadow inspired him to become more powerful.
  • Hope Crusher: Infinite thrives on driving his opponents to despair with his immense power. As he tells Silver:
    Infinite: This wasn't part of my agenda, but I'm always happy to crush a hero. It keeps the rabble in line. Shows them that there is no hope.
  • Humanoid Abomination: He appears to be the same kind of Funny Animal species as the main cast, but his design incorporates traits from different animal species, he possesses powers beyond anything seen so far, and Tails is unable to make sense of the readings he gives out on the Miles Electric. He's really a Funny Animal (a jackal, specifically) like everyone else, but powered up by the Phantom Ruby.
  • I Can Still Fight!: His final words before he disappears.
  • I Have the High Ground: Infinite is fond of hovering high above the heroes as a display of his power and superiority.
  • Image Song: Aptly titled "Infinite".
  • Imagination-Based Superpower: The Phantom Ruby allows him to conjure up anything he feels like to attack Sonic and the others with, ranging from lasers to cannons to an outright Colony Drop using a localized burning star that fills the sky, the requirement being that they have to come in contact with the Phantom Ruby's red cubes or be in close enough physical proximity to Infinite. They're actually just illusions, but they will still be injured or killed as if the illusions were real.
  • Immune to Flinching: Played With during his boss fights. If struck by Sonic's Homing Attack or the Avatar's Wire Attack, he'll recoil from the impact. But if struck by the Avatar's Wispon attacks, he won't react outside of grunts of pain.
  • Inferiority Superiority Complex: Heavily implied to have one. Episode Shadow reveals that prior to the game, he was the captain of a mercenary team and touted himself as the "Ultimate Mercenary". That all changed one fateful day when he and his squad were hired by Eggman to protect one of his laboratories in Mystic Jungle, where they encountered Shadow the Hedgehog. Shadow effortlessly destroyed his entire squad and handed Infinite a humiliating defeat, which would lead to Infinite's vow to become stronger and led to him obtaining the power of the Phantom Ruby. This is why he constantly boasts about his power: to make himself feel strong. This is also why he objects to Eggman's strategy to retreat after the Death Egg is destroyed. To him, retreat is a sign of weakness.
  • Infinite: It's his name. Duh. Fittingly enough, Hoobastank sings the main theme of Sonic Forces, and their name is often stylized as h∞bastank, also containing an Infinite symbol. He also has the infinity symbol decorated on the soles of his boots.
  • Informed Species: He's a jackal, despite looking very little like one.
  • Interface Screw: Throughout the Capital City stage, Infinite will occasionally pop in and use the Phantom Ruby to screw with the gravity.
  • I Work Alone: Espouses this sentiment during the final battle with him. Having his entire squadron wiped out by Shadow likely inspired a desire to never again rely on others.
    Infinite: Friends are nothing but a fleeting illusion. You can count on nobody but yourself.
  • Knight of Cerebus:
    • While Sonic Forces is one of the darker Sonic games to date, it still has some lighthearted scenes at times. Any scene involving Infinite, however, is utterly devoid of humor or levity. Notably, he is one of the few Sonic villains to be explicitly seen killing people onscreen.
    • This is best shown in Stage 16, Capital City. Knuckles, learning that Eggman's army is undermanned in his home base in Metropolis, decides to order a full-scale assault on the city. Things quickly go to hell when Infinite arrives and, at the doctor's command, activates the Phantom Ruby's power to create giant, grotesque illusions of himself, throwing the Resistance into chaos. By the time the stage ends, 80% of the Resistance is utterly annihilated.
  • Lack of Empathy: Infinite only cares for causing as much destruction and suffering as he can. He considers friendship to be a waste.
  • Leaning on the Fourth Wall: He remarks to Eggman that Sonic has beaten him "for decades."
  • Literal-Minded: After Shadow wrecked his shit two months before the start of the game and told him to "never show your pathetic face around me again", Infinite took that to mean he should start wearing a mask.
  • Living Shadow: He resembles one quite well, especially when his Battle Aura is activated, and bears some similarities to Blaze's concept art.
  • Loves the Sound of Screaming: After decimating the Avatar's squad, he deliberately allowed them to run away and live for this reason.
    Infinite: Give in to your fear. Flee, screaming, and I'll let you live.
  • Madness Mantra: I AM NOT WEAK!
  • Malevolent Masked Man: Wears a metallic mask shaped like a fox's head and is one of the main villains of the game.
  • Mask of Power: Whenever he gets ready to attack, the right eye on his mask glows red.
  • Master of Illusion: The Phantom Ruby's true power. It doesn't actually warp reality, but it mind-rapes anyone within range with illusions and hallucinations that seem so real that whatever happens in said hallucinations happens for real. In his boss fights, this is done through his energy cubes. Contact with them sends the player into a glitching illusion where they are attacked by objects manifested by the Ruby's power.
  • Mineral MacGuffin: He has some relation to the mysterious purple gemstone that is referred to as the "Phantom Ruby" by an in-game guide that everyone was after in Sonic Mania, implied by the sound it makes. The game reveals that the Ruby was given to him by Eggman.
  • Mismatched Eyes: His right pupil is blue and his left pupil is gold.
  • My Hero Zero: Inverted, he is an antagonistnote , so he wouldn't be a hero. In earlier drafts, he is referred to as Zero. (Not to be confused with ZERO AKA E-100 Alpha.)
  • Mysterious Stranger: Infinite is presented as this, during the main story anyway. Sonic never discovers Infinite's backstory during the game. Only Shadow knows what he was before becoming what he is now.
    Sonic: I don't know anything about you. Not even your name.
  • Nice Job Fixing It, Villain!: Dropping the prototype Phantom Ruby screws him and Eggman over in the long run.
  • No Name Given: Even before taking the moniker "Infinite", we only know his nickname "The Ultimate Mercenary". His actual name is never revealed.
  • Non-Standard Character Design: Used intentionally to give Infinite an otherworldly, alien feel to him. While designed in the same Cartoon Creature style as other characters, his design incorporates both foxlike traits as well as the hairstyle used by both hedgehogs and echindas. He also has a red outline around him and is constantly emanating a purple aura that occasionally flickers with red static, as if he's out of sync with the Sonic universe.
  • No Sense of Personal Space: When confronting the Avatar in Metropolis, he teleports right next to the Avatar, his mask mere inches away from his face, taunting him on whether he'll fight or run away again.
  • Not So Different: Presumably the reason he loves tormenting the Avatar: he lost his squad and was called weak by a much more powerful opponent. It reminded Infinite of himself that day when he takes out the Avatar's squad and calls him "weak". Except now Infinite's the big dog who belittles his opponents, much like Shadow.
  • Not Worth Killing: His initial reaction to Sonic after their second fight, similar to King Arthur.
    Infinite: As I predicted. You're not even worth the effort to finish off.
  • Obviously Evil: Let's see: Has black fur and clothing? Check. Wears a metallic mask shaped like a fox's head that hides his face save for an eye that has a gold pupil and red sclera? Check. Glows with a red outline and emanates a purple haze with red glitching static? Check. Is the right-hand man to the main antagonist of the series? Check. Has a demonic, echoing voice? Check. Openly relishes death and destruction? Check. Yep, definitely a bad guy.
  • Ominous Visual Glitch: His aura occasionally has a glitch-like effect in some spots. The official Sonic Youtube channel's upload of his theme also has the image glitching out. His virtual reality constructs have the same glitching effect. Just before the final level of the game, Eggman is able to make him vanish like his constructs by recalling the Phantom Ruby, implying that part or all of his physical form had become a phantom construct.
  • Omnicidal Maniac:
    • Infinite and Eggman's plan in Sonic Forces is to destroy the world and rebuild it from the ashes in their image.
      Infinite: We move forward with the plan?
      Eggman: Of course! When it's complete, the Resistance will be erased. The world will be nothing but ashes, from which a glorious Eggman Empire will rise!
      Infinite: And the Resistance will yield to the Phantom Ruby's power. All will submit.
    • The vision he got from the Phantom Ruby in the prequel comic implies he may have had ambitions of being one of these before he became what he is now.
  • One Steve Limit: One of his names is "Zero" in a draft. He is not to be confused with ZERO AKA E-100 Alpha.
  • Parody Sue: Has many traits of one of the Villain Sue variety. He's portrayed as faster than Sonic, able to curbstomp some of the strongest heroes in the series, forms a Legion of Doom of some of its strongest villains subservient to him, and spends every other sentence bragging about how powerful he is... because his one true, definitive power is the ability to make Your Mind Makes It Real illusions that make himself appear all-powerful. In actuality, he's nothing more than a sadistic bully with more power than he has any right to, and once ways around his power are found, he's not nearly as invincible and perfect as he thinks he is and his sadism screws his side over royally.
  • Pitiful Worms: Constantly insults and belittles Sonic and the Resistance, referring to them with such terms as "rabble" and "ants" and "pests". In the Japanese version, he's quite fond of calling them "trash".
  • Power Crystal: The source of Infinite's power is the gem on his chest, a finalized version of the Phantom Ruby prototype created by Eggman.
  • Power Incontinence: Implied. After being defeated by Sonic and the Avatar, Infinite's body begins to glitch and warp like his virtual reality constructs, implying that they did so much damage to Infinite that his body couldn't contain or control the Phantom Ruby anymore.
  • Power of the Void: He can attack with Hard Light cubes of Pure Energy. A more straightforward example is the Phantom Ruby's ability to create Null Space, a seemingly inescapable void in space-time where nothing exists. He uses this in an attempt to kill Sonic, but Sonic manages to escape with help from the Avatar.
  • Powers Do the Fighting: Gameplay-wise, anyway. In cutscenes, he's a dynamic, hands-on fighter who pelts opponents with energy attacks. In his boss fights, he mainly floats around and attacks with his cubes, arranging them in various shapes. Of course, given the nature of his powers, it's not entirely clear how much of what Infinite does is actually him and how much is an illusion created by the Phantom Ruby.
  • Psycho for Hire: He's a Sadist who really enjoys his work as Eggman's Dragon. He also really enjoyed being a mercenary and willingly joined Eggman. Deconstructed to a degree, as his sadism is a Fatal Flaw that ultimately bites him and Eggman in the end and causes him to make mistakes that even Eggman realizes were blunders.
  • Psychopathic Manchild: Pretty much the definition of the trope. His whole motivation basically boils down to Infinite throwing a massive tantrum over being humiliated by Shadow. His "I AM NOT WEAK!!!" rant says it all. Some may even compare him to Zant.
  • Punch-Clock Villain: He was originally just another hired goon in Eggman's employ. Then Shadow wrecked his shit, driving him over the edge and turning him into what he is today.
  • Purple Is Powerful: The purple gem, referred to as the "Phantom Ruby" in Sonic Mania that is the source of Infinite's power, is able to transport people to another destination and can also disable Super Sonic.
  • Readings Are Off the Scale: While no numbers are given, Tails states that the readings he's getting off of Infinite don't make sense. Given the true nature of his powers, this was likely because what it was picking up and what Tails and Sonic saw happening didn't match up.
  • Reality Ensues:
  • Reality Warper: Of a sort. Infinite can't control conventional reality per sé, but he possesses absolute control of reality for anything caught in the Phantom Ruby's field of effect, casting a world of illusion that becomes tangible reality for all afflicted. This can stem anywhere from confusing the senses, losing sense of time, altering the terrain, or dropping a star from the sky.
  • Recurring Boss: You fight Infinite three times throughout the game. The first fight is with Sonic, the second fight is with the Avatar, and the final battle is with Sonic and the Avatar together.
  • Red and Black and Evil All Over: He's colored black and red, and radiating reddish energy, and he is certainly not to be trifled with.
  • Red Eyes, Take Warning: Subverted. He appears to have red sclera, but Episode Shadow reveals that it's just the red-tinted glass of the mask. His sclera is actually white.
  • Red Oni, Blue Oni: The blue to Eggman's red. Best shown in their reaction to Sonic and the Avatar escaping the Phantom Ruby's Null Space. While Eggman is naturally having a Freak Out, Infinite merely responds with an unamused scoff. Ironically, Eggman turns out to be more of a Crazy-Prepared No-Nonsense Nemesis (Blue), while Infinite turns out to be a Stupid Evil Sadist (Red).
  • Restraining Bolt: Exactly how it works isn't made clear, but when Infinite fails one time too many, Eggman proves capable of effortlessly recalling him and reclaiming the Phantom Ruby and Infinite is powerless to do anything about it.
  • Sadist: Hoo boy. Infinite absolutely relishes in causing terror and pain in others and he is not afraid to let it be known. A throwaway line in his theme song outright says that Infinite is at his best when people are at their lowest. Deconstructed, as his rampant sadism costs him and Eggman in the end.
    Infinite: (To the Avatar) Fine, I will teach you fear, then pain, and then... Well, at least the fear and pain will end.
    Infinite: (To the Avatar) I can taste your terror, child. All that anxiety and doubt... it's delicious. (Fires an energy blast in front of the Avatar, intentionally missing just to startle them) Give in to your fear. Flee, screaming, and I'll let you live. (Evil Laugh)
  • Sanity Has Advantages: While Infinite is extremely dangerous, he's also clearly an insane sadist. This screws over him and Eggman on several occasions, as he prioritizes his sadism over pragmatism.
  • Sanity Slippage: In issue four of the prequel comic, Infinite was a ruthless mercenary, but a relatively stable guy (though his Phantom Ruby-induced vision of a desolate world implied there was some element of insanity). However, the death of his squad and his own humiliating defeat at Shadow's hand brought all of that madness to the surface.
  • Skyward Scream: In his Villainous Breakdown.
  • Small Name, Big Ego: Even before taking up the mask and becoming reborn, he considered himself to be the "ultimate mercenary" before Shadow took him down in one battle. Even after his upgrade, Infinite isn't as big of a fish as he thinks he is, as he was little more than a pawn for Eggman that the good doctor disposes of the moment he's screwed up one time too many.
  • Smug Super: And how! Infinite has a bigger ego than Sonic and Shadow combined and has all the power to justify it now. He was a relatively weak Miles Gloriosus originally.
  • The Social Darwinist: Espouses this sentiment during his fight with the Avatar. As revealed in Episode Shadow, this sentiment is likely the result of his effortless defeat at Shadow's hands. He never again wanted to be as weak as he was that day, and that conviction and self-loathing seems to have inspired a hatred for those who are weak.
    Infinite: (To the Avatar) You must be a straggler who got left behind. The strong will always vanquish the weak. You have only your own frailty to blame.
  • Soft-Spoken Sadist: Rarely raises his voice above a cold, Creepy Monotone, even when committing acts of mass slaughter.
  • Space Master: While the Phantom Ruby's powers are mostly centered around illusions and virtual reality, it does give Infinite some degree of spatial manipulation, mostly centered on controlling gravity. In Central City, Infinite uses the Phantom Ruby to screw with the gravity and he's also capable of creating Null Space, a seemingly inescapable void in space-time where nothing exists.
  • The Starscream: Subverted. While Infinite does disagree with Eggman at times, he remains loyal to him to the end.
  • Start of Darkness:
    • Episode Shadow reveals that he was once an ordinary jackal and a mercenary hired by Eggman to protect his lab in Mystic Jungle, where he encountered Shadow. After a humiliating defeat at the dark hedgehog's hands, he vowed to become stronger, leading him to become Infinite.
    • The fourth and final tie-in comic shows it started a little sooner when despite failing to steal anything from Eggman, Eggman offers Infinite and the Jackal Squad the chance to become stronger and take over the world. Infinite is more than happy to oblige.
  • The Stoic: To the point of Dissonant Serenity. Infinite is never seen to be anything other than unnervingly calm, barely raising his voice outside of the occasional Evil Laugh and two This Cannot Be! moments. It helps that the mask hides his facial expressions. Episode Shadow shows that he was more emotive prior to the game.
  • Story-Breaker Power: Infinite is able to create "virtual reality constructs" that have the personalities and powers of the characters they are based on, so it's possible for him to create an army of giant Shadows, Biolizards, Chaoses, Dark Gaias, Zavoks, Metal Sonics, Bigs, etc., but why he does not do so before the climax is unclear.
  • Stupid Evil: His primary flaw is that he prioritizes indulging his own sadism over the mission, with disastrous results for both himself and Dr. Eggman.
  • Supernatural Gold Eyes: Well, only one eye, but his eye has a gold pupil with red sclera.
  • Superpower Lottery: The Phantom Ruby's illusion powers are incredibly versatile and dangerous. With the Phantom Ruby, Infinite can create intricate illusions so real that anything that happens to the victim in the illusion affects them for real. Infinite can also use this power to create virtual reality constructs of any character, complete with the memories, powers, and personalities of the original, and he can alter them to make them stronger and more dangerous, such making Metal Sonic bigger and granting him electrified versions of his energy cubes. Infinite can also use the Phantom Ruby to create Null Space, a seemingly inescapable void in space-time where nothing exists, much like a real-life black hole. Apart from that, Infinite has flight, super speed, super strength, energy blasts, and incredible durability.
  • Super Soldier: Episode Shadow reveals that he's basically one for Eggman. Infinite was already a highly skilled mercenary, but the "super" part didn't come in until he gained the power of the Phantom Ruby.
  • Super Speed: He's quick enough to Flash Step. It’s implied that it's not just actual speed, as he can seemingly teleport. Infinite's real power and the strange readings imply he can't even do that and is more using the Phantom Ruby to appear capable of it. In practice, Sonic is capable of keeping pace with him once the Phantom Ruby's power isn't at play.
    Tails: Whoa. This guy is faster than Sonic!
  • Suspiciously Similar Substitute: Infinite's personality and elements of his backstory loosely recall Mephiles the Dark. Like Mephiles, Infinite enjoys causing pain in others. Also like Mephiles, a weaker Infinite was defeated by Shadow in the past and left with words to hold onto. Furthermore, when the empowered Infinite meets with Shadow again and reminds him of their past while calling him by name, Shadow is confused, just like when Mephiles reunited with Shadow.
  • Technopath: The power of the Phantom Ruby transformed the Hard-Boiled Heavies from ordinary Eggrobos into superpowered machines.
  • This Cannot Be!: His normally unshakable demeanor has faltered on two occasions, the first being when the Avatar manages to survive Infinite's illusion during his fight with them, and the second being when he's defeated for the final time.
  • Too Important to Walk: Highlighting his Smug Super nature, Infinite is never seen walking and prefers to just fly around as a demonstration of his power.
  • Underestimating Badassery:
  • Unskilled, but Strong: Implied: While Infinite has some skill in hand-to-hand combat thanks to his mercenary background and can steamroll through a good chunk of the cast, he is entirely reliant on the Phantom Ruby in combat. His boss fights mainly consist of him letting his energy cubes do all the work, with his only physical attack being an easily avoidable Dash Attack. In cutscenes, his fighting style basically boils down to "throw energy blasts at opponents until they die". He's shown to have trouble when its powers are weakened or neutralized. In addition, Eggman shows himself far more proficient in the Phantom Ruby's use.
  • Vile Villain, Saccharine Show: Infinite skirts the line about as razor-thin as you can get. His constant death threats and assurances that he will make things slow and painful for any opposition still avoid bumping the rating above "E-10+" (so no worse than the highest rated games in the franchise like Shadow the Hedgehog, Sonic the Hedgehog (2006), or Sonic Lost World) and don't necessarily remove the usual Sonic-feel from the scenes he's not in, but he definitely changes the tone of the game in comparison to the rest of the franchise.
  • Villain Ball: After defeating Sonic in the Mystic Jungle, he lets him live, deeming him Not Worth Killing. Eggman calls him out on doing so, knowing that Sonic will continue to be a threat as long as he's still alive, and is ultimately proven right.
  • Villainous Breakdown: He has a huge one after Shadow humiliated him, going into a insane freak-out which pushes him into becoming Eggman's weapon. He also has another (albeit brief) one when he starts to disappear after being defeated for the last time.
    Infinite: [notices his hand shaking] I... I'm shaking... Me!? Me... Afraid...!? Urgh. Pathetic!? Me... he's calling ME weak!? No! I am not weak! I'm... I'm not. I'm not weak! I AM NOT WEEEEAAAAAAK! URRRAAAAAAAAAAAGHH!
  • Villain Song: Has one that can be heard here, which goes out of its way to describe just how dangerous and powerful he is and how he'll destroy anything in his way.
  • Visual Pun: Infinite's habit of hovering above the heroes means that he's literally "looking down on them".
  • Walking Spoiler: He's a major driving force behind the conflict of Sonic Forces. The Phantom Ruby also counts as this due to being the same one from Sonic Mania.
  • Was Once a Man: According to an interview with Izuka, he used to be a regular guy like Sonic and Co. before aligning himself with Eggman. Episode Shadow reveals that he was once an ordinary jackal and a mercenary hired by Eggman to protect his lab in Mystic Jungle, where he encountered Shadow. After a humiliating defeat at the dark hedgehog's hands, he vowed to become stronger, leading him to become Infinite.
  • We Can Rule Together: Eggman offers this to Infinite after a fight with him, and Infinite accepted the offer.
  • What Happened to the Mouse?: After his final defeat in Sonic Forces, he fades away into a light and flies into a tower, after which Tails tracks his Phantom Ruby leading to Eggman's final mecha with Infinite nowhere to be seen. Exactly what Eggman did is unclear.
  • White Hair, Black Heart: He has ghostly white hair and he's one of the bad guys.
  • Who's Laughing Now?: His main ambition for utilizing the Phantom Ruby. Rather expectedly, Shadow, the one who started his embitterment, is the first person he personally toys with before starting about capturing Sonic.
  • With Great Power Comes Great Insanity: Before obtaining the power of the Phantom Ruby, Infinite was just a mercenary who did his job and was a relatively stable guy all around (though the vision he received from the Phantom Ruby implies some degree of mental instability). By the time of the game, the Ruby's power has clearly gone to his head and has turned him into a sadistic, power-hungry sociopath.
  • The Worf Effect: His first meeting with Sonic ends with the hero utterly trounced.
  • Worthy Opponent: Completely averted. He treats everyone he fights with utter contempt.
  • You Have Failed Me: All but said. After the virtual sun plan fails thanks to Infinite's screw-up and he's defeated by Sonic and the Avatar, he's teleported away against his will. Tails then tracks his Phantom Ruby underground... leading directly to Eggman's final mecha powered by it, with no sign of Infinite.
  • Your Mind Makes It Real: Revealed to be the actual power of the Phantom Ruby: it creates illusions that nonetheless feel real to the victim's brain, causing injuries taken in the illusion to occur to the victim in reality.

Example of:
