Characters / Sonic The Hedgehog-Team Sonic
aka: Sonic The Hedgehog Main Trio

The three primary protagonists of the series, aptly named Team Sonic (or Team Heroes depending on the game), consisting of Sonic, Tails, and Knuckles. Whenever a threat rears its ugly head, you can bet these three will be at the center of the conflict in some way. The roster tends to vary depending on the game (Amy tends to join them a lot of the time), but the ones listed here are considered "staples" of the series.
    open/close all folders 

    Tropes applying to the trio as a whole 
  • Airplane Arms: All three do this when running full speed.
  • Badass Crew: By themselves they are already capable, but when they work together, there is almost no foe that can take them down. Sonic Heroes is even built around this concept with three other teams in addition to Team Sonic.
  • Bash Brothers: As mentioned above, Sonic Heroes is built with this concept in mind, using the abilities of the three in tandem to progress.
  • Beware the Nice Ones: All 3 of them are extremely nice, but if you're hanging with the wrong crowd, expect a beating from them.
  • Brains and Brawn: Tails is the brains to Sonic & Knuckles` brawn; although all three are quite strong and sharp in their own ways.
  • Cast Herd: After Sonic the Hedgehog 3, the three had more or less equal spotlight and screentime, with only Sonic barely eclipsing the other two, but only by a small margin. However, recent games have began to focus primarily on Sonic himself with Tails being turned into an NPC Non-Action Guy, and Knuckles being severely Out of Focus.
  • Chromatic Arrangement: Sonic blue, Tails yellow, Knuckles red.
  • Elemental Powers: Various games give them this affinity.
  • Fighter, Mage, Thief: It's even reflected in their personalities.
    • Fighter: Knuckles, who prefers close combat and uses his fists to plow through his opposition.
    • Mage: Tails, who is the "average" of the three in physical abilities, makes up for it with his various gadgets.
    • Thief: Sonic, who uses his various acrobatic and swift movements to make up for his lack of power. (Compared to Knuckles, anyways.)
  • Four-Temperament Ensemble: The three along with Amy.
    • Sonic (Phlegmatic) : He's the leader of the gang. He can be very impulsive and most likely to take action should a problem present itself. He's witty, easygoing, very loyal to his friends, and a condescending smart aleck towards his rivals and enemies.
    • Tails (Melancholic) : He's the technician of the gang, his intelligence rivals that of Dr. Eggman's. He's very friendly, reliable, and meticulous but greatly lacks confidence in his own abilities. Nonetheless, he's driven to chart the course and guide his friends.
    • Knuckles (Melancholic) : He's the muscle of the gang. He's overly stubborn, somewhat calm but very short-tempered, and terribly single-minded. He's got a rivalry with Sonic, but takes things more seriously. He's a driven individual who takes his duties as protector of Angel Island along with the Master Emerald very seriously although he's pretty easy to outsmart.
    • Amy (Choleric) : She's the leader of her own group (Team Rose) but sometimes resorts to going along with Sonic and his crew. She can be very compassionate and overly concerned with other people's problems. However, she can be very stubborn and has a fiery temper. Because of those traits, she can come across as very overbearing and a nuisance sometimes (especially to Sonic).
  • Freudian Trio: Although each one of them have traits of all three Freudian personality types. Sonic as The McCoy who tends to act purely on impulse and does whatever he feels is a good idea at the time, though in Sonic Lost World he shows some Kirk traits when breaking up a fight between Tails and Eggman. Knuckles as The Spock who tends to focus primarily on his job of protecting the Master Emerald and rarely concerns himself with matters outside of that. Although his anger issues give him some McCoy traits. Tails as The Kirk who tends to mediate in-fighting between the other two, and his intelligence gives him some Spock traits. He also has some McCoy traits when agitated by something, as shown in Sonic Lost World.
  • Funny Animals: ...Well, duh...
  • Heterosexual Life-Partners: Because Knuckles tends to spend more time alone on Angel Island, Sonic & Tails tend to be the ones who kick off the plot. They're almost never seen without the other and most games focus on them being such great partners. It helps that Sonic adopted Tails as his surrogate little bro.
  • Image Song: "We Can" (for the three as Team Sonic).
  • Improbable Age: Sonic is 15, Knuckles is 16, and Tails is 8. Yet, they've gone on to save the world and be far more competent than the military.
  • Kid Hero: According to official profiles, none of them are over 18. Heck, Tails isn't even 10.
  • Limit Break: Their Team Blast, "Sonic Overdrive", in Sonic Heroes. It does major damage to all nearby enemies, and enables the use of the Light Speed Attack for 10 seconds until its cooldown timer runs out.
  • Nice, Mean and In-Between: Respectively, Tails is the nice one for being humble and respectful to others, The mean is downplayed with Knuckles, as he's not technically mean, but has nastier portrayals like Sonic Battle and Sonic Rivals, and Sonic is in-between due to having a bit of an ego trip and a snarky attitude but ultimately a nice guy overall.
  • Pintsized Powerhouses: They're all pretty small and rather strong, but Knuckles stands out among them.
  • Power Trio: They've been seen together since the beginning of Sonic 3 & Knuckles.
  • Primary-Color Champion: Sonic, Tails, and Knuckles are respectively blue, yellow, and red and are the main heroes of the franchise.
  • Ragtag Bunch of Misfits: A nomadic blue hedgehog, a super-smart helicopter-tailed fox, and a lonesome guardian of a giant green rock, all united by their efforts to save the world.
  • Red Oni, Blue Oni: Both Knuckles and Tails usually play Blue to Sonic's Red. Each of them can function as either Blue or Red depending on the game, however.
  • Sensitive Guy and Manly Man. Sonic (manly man) and Tails (sensitive guy). However, when it comes to Knuckles, Sonic is the Sensitive Guy while Knuckles is the Manly Man.
  • Super Mode: Sonic and Knuckles were able to harness the power of the Chaos Emeralds and Tails the Super Emeralds up 'till Sonic 3 & Knuckles, but nowadays, it seems only Sonic and the other male hedgehogs are allowed to go Super.
  • Super Speed: They're all pretty fast; Sonic is just the fastest of them, notably in Sonic Colors. Even in speed formation, Sonic is going slow enough for the others to keep up, and they're all speeding through every environment.
  • Super Strength: They're all pretty strong since their primary mode of attack is slamming into things and they've all taken down armored robots single-handedly. Knuckles is decidedly the strongest, though.
  • True Companions: Despite their backgrounds and differing personalities, they are shown to care for one another. Particularly Sonic & Tails.
  • Vitriolic Best Buds: All three of them tend to tease and snark at the other, especially Sonic and Knuckles.

"What you see is what you get, just a guy that loves adventure. I'm Sonic the Hedgehog!"

First Appearance: Rad Mobile (cameo)
Debut in-series: Sonic the Hedgehog

Voiced by: Takeshi Kusao (Japanese, 1993), Masami Kikuchi (Japanese, OVA), Keiko Toda (Japanese, Sonic Underground), Junichi Kanemaru (Japanese, 1998-present), Tomokazu Seki (Werehog form, Japanese, Sonic Unleashed), Keiko Utoku, (Sonic the Hedgehog CD), Jaleel White (English, AoStH, SatAM, Sonic Underground), Martin Burke (English, STH: The Movie), Ryan Drummond (English, 1999-2005), Jason Griffith (English, Sonic X, 2005-2010), Roger Craig Smith (English, 2010-present)

The main character of the franchise. A cobalt-blue anthropomorphic hedgehog with attitude and plenty of personality who lives up to his name by being able to run at superhuman speeds. Not much is known about Sonic's past aside from that he was born on Christmas Island. One day, he noticed all of his animal buddies began disappearing and the culprit was none other than Dr. Eggman. After foiling the doc's plans, Sonic would then make it his business to foil whatever Evil Plan the doc cooked up, establishing their long rivalry. Over time, Sonic has faced bigger and larger threats alike while making a whole slew of allies along the way.

Sonic is described as the wind; unpredictable, and always moving from place to place and never settling down for long. Laid-back, carefree, and armed with a wit as sharp as his quills with an ego to match.

  • Absentee Actor: There are exactly three games in the entire franchise where he does not appear at all, not even as a cameo; Dr. Robotnik's Mean Bean Machine, Tails Skypatrol and Tails and the Music Maker. He is also absent from Tails Adventure, but his likeness makes a very small cameo as an item for Tails to use.
  • Ageless Birthday Episode: Despite it being his birthday in Sonic Generations, he's still 15 years old (or at least, Sega of Japan never bothered to update his character page).
  • All-Loving Hero: As far as the games go, no matter what happens, Sonic never holds grudges and easily makes friends out of former enemies. If it's to save the world, he won't even hesitate to work alongside Eggman without a second thought, although he wouldn't exactly be happy about it.
  • Always Accurate Attack: His signature Homing Attack that he has had since Sonic Adventure, which is usually shared with other "Speed"-type characters. Sometimes, it's shared with all of the characters.
  • Always Someone Better: To Metal Sonic.
  • Anti-Hero: Played with. While Sonic has his faults, they don't get in the way of his heroism. However, as his own theme song (see Sonic Adventure) states, he doesn't like to follow others' values or beliefs and lives by his own morals and codes, and always makes his choices based on what comes natural to him by his own feelings. He also has a propensity for a LOT of vandalism in his heroic acts. Still, deep down, he will always come out as the hero who saves everyone at the end of the day. Usually, though, his rare unheroic acts are ultimately still for the greater good.
    • While he ultimately comes out the hero, Sonic Adventure 2 includes him destroying countless military robots (before even having any idea that Eggman was up to something), resisting arrest by escaping from GUN, breaking out of Prison Island, and, oh yeah, HIJACKING THE PRESIDENT'S CAR.
    • in Sonic Unleashed (and arguably Sonic Generations), he causes what must be millions in non-Eggman property damage during his daytime runs.
    • Sonic Colors starts with him deliberately vandalizing Eggman's park despite not (yet) having any evidence of Eggman's wrongdoing.
    • In Sonic and the Black Knight, he even willingly attempts to become the story's villain by killing King Arthur to save Camelot from his tyrrany. He even lampshades it. But to be fair, King Arthur was the real villain at the time.
    Sonic: I told you, I don't mind playing the bad guy once in a while.
  • Art Evolution: Sonic has gone through a lot of redesigns in the series, most drastically his design overhaul from Sonic Adventure and onward. The only other character that exceeds him in redesigns is his own opponent, Dr. Eggman.
  • The Artifact: While his spin moves have always been a hallmark of the character's abilities, some aspects of them eventually became obsolete in the context of later entries. For instance;
    • Sonic's spindash move, a staple ability since Sonic the Hedgehog 2 that was meant to make it easier for Sonic to gain momentum and attack (plus making it easier to go up slopes), was largely downgraded in power as an ability and basically made obsolete around the later 3-D and Sonic Rush games, due to the new boost ability essentially serving the same purpose as it and its sister move, the Super Peelout, but without the idle chargeup time needed. Later games such as Sonic Unleashed eventually dropped the ability to use the move altogether, although it still makes appearances in side-scrolling titles such as Sonic the Hedgehog 4 and Sonic Lost World.
    • Likewise, the spin attack, Sonic's basic method of simply ramming into enemies while spinning in air, was made obsolete in the 3-D games as of Sonic Adventure, due to the introduction of the Homing Attack (which made an early bird appearance as a shield in Sonic 3D Blast). While his spin attack is still a main move in the side-scrollers, the homing attack still accompanies it as a backup move now.
    • Sonic's initial purpose as a character became this over time. Sonic was originally concieved by Sega not only as their mascot, but as a direct competitor and the antithesis of the Super Mario Bros. video game series. Once Sega dropped out of the hardware business and started publishing games on Nintendo, and when Sonic and the plumber had a few crossover games together, that aspect of Sonic was simply made obsolete and was dropped altogether in favor of solely being Sega's flagship franchise, and a friendly competitor to the Mario franchise instead.
    • His ability to grind rails was added to Sonic Adventure 2 for the sake of Product Placement (his shoes were redesigned to resemble a real life pair of Soap-brand rail grinding shoes). Afterwards, the ability was kept without the Product Placement.
  • Badass: Because who else can plow through robots, dark beings, and even gods at super speed, all while having fun at it? Hell, he's so badass he temporarily outran a black hole.
    • Even better, Sonic has progressively gotten stronger and stronger throughout the series. A good example, even if not from a good game, is Sonic's bouts with Silver in Sonic 06. Sonic DID win his first fight, but was then utterly helpless after he let Silver slip an attack in. In their second bout, Sonic didn't even get a move in; he needed to be saved by Shadow. Come Sonic Generations and the rival battle with Silver, despite Silver getting upgraded attacks and being able to keep up, if not outpace Sonic, Sonic dominates Silver, and finishes the battle with style. Not only that, but in Sonic Adventure, Sonic needed the positive strength of all seven chaos emeralds to take down Chaos. Once again, come Sonic Generations, Sonic goes to fight Chaos again. Without emeralds. Sonic the Hedgehog goes and fights the GOD of Destruction and Water, and wins without going Super. Badass.
  • Badass Adorable: Even he has his moments where he just looks cute, mostly pre-Adventure.
  • Badass Armfold: He does this sometimes, often when he's bored.
  • Badass Boast: He's let out a few over the years, and he backs each one up in spectacular fashion:
  • Badass Bookworm: No genius, but he is a fan of the Arabian Nights; not only did he go into the world, he does occasionally mention reading up on a few things.
  • Badass Cape: As Excalibur Sonic.
  • Badass in Distress: In Sonic Adventure 2 where escapes from GUN once, but is captured again partly due to Shadow. He gets rescued by Tails and Amy.
  • Badbutt: One of the poster children of this trope. Which makes sense, considering how fitting the above trope into a kid-friendly environment has been a primary hallmark of the series since its inception.
  • Bash Brothers: Has been this with Tails since Sonic 2. He also plays this with Knuckles when the two put aside their differences, which is also the case with Shadow. He even does this with his past self in Sonic Generations.
  • Berserk Button:
    • At least 4: Don't call him a rat, don't mess with his friends, don't stop him from eating his chili dogs, and DON'T threaten the peace, freedom, and/or well-being of others. He won't take it well.
    • To put this into perspective, Erazor Djinn managed to press three of those buttons in the same game! To say it didn't end well for him would be putting it mildly.
    • If you hurt Tails, Sonic will stop at nothing to destroy you.
  • Beware the Nice Ones: He's probably the nicest and most polite character next to Tails and Cream, but push his buttons and... well... Erazor Djinn note  learned the hard way.
  • Big Brother Mentor: He's this to Tails in most of the games and adaptations.
  • Big Brother Instinct: Sonic tends to be pretty laid-back and easy going, but the second Tails is in any sort of trouble he shapes up extremely quickly.
  • Big Damn Heroes: Once a game. expect this trope to happen.
  • Big Eater: Despite his small size, he has a huge appetite; justified due to the fact that he burns a lot of calories constantly running at such high speed all the time.
  • Black Hole Belly: He literally becomes one in the DS version of Sonic Colors when he transforms into the Violet Void form. He will even consume the entirety of the Frigate Skullian, provided its HP meter is depleted enough.
  • Blood Knight: While he doesn't go out of his way to seek a conflict or hurt people, there is no doubt Sonic loves a good fight with anyone that can challenge him. The thrill of the adventure is what he lives for.
  • Blow You Away: Ever since Sonic Adventure 2, he could use wind-based attacks, some of which use his great speed, some of which don't, although the games never elaborate much on this.
  • Blue Is Heroic: Arguably the poster child of this trope in video games. His blueness represents freedom and clear blue skies, as well as his generally easygoing nature. This is put in contrast with Eggman's redness as well as Knuckles' intense red and Shadow's red accents.
  • Boisterous Bruiser: Generally very excitable and willing to take down anyone threatening the world.
  • Book Dumb: Sonic is often shown to be highly resourceful and even has plausible showings of wisdom. He's also been shown as being capable of operating the Tornado with equal proficiency to Tails, and clearly values literature. However, he isn't the most educated guy around, usually requiring more intellectual teammates such as Tails to explain the science of it all.
  • Breaking the Fourth Wall:
    • The character most likely to do so, such as in Sonic Colors.
    • Even in his first appearance, he would stare at the screen and tap his foot impatiently if left idle.
  • Brilliant, but Lazy: He's one of the strongest and most influential people on the planet, but he spends much of his time roaming the planet or relaxing and only saves the heroics for when it's appropriate.
  • Brought Down to Normal:
    • In Sonic 3, Knuckles cancels out his otherwise very powerful Super Sonic form with a single punch, and this also knocks the Emeralds out of him.
    • In the opening of Sonic Unleashed, Eggman uses a machine to force Sonic out of his super form and rip the Chaos Emeralds from him, which in turn causes Sonic to gain a new Werehog form.
    • Occurs in Sonic Labyrinth when Eggman takes his speed and ability to jump by replacing his shoes with slow down versions of his own creation. However, he can still spindash just fine.
  • Calling Your Attacks: "Sonic Wind!" "Chaos Control!" "Speed Break!" "Time Break!"
  • Catch Phrase: "I'm Sonic! Sonic the Hedgehog!"
  • Characterization Marches On/Flanderization: The degree of his personality tends to vary from game to game, especially in the 3D era. He had a fairly neutral personality in the likes of the two Adventure games, and Storybook games; being fairly confident in his abilities, but knowing when to get serious when a real threat presented itself. In Sonic 06, all of the quirky parts of his personality were written out and he's mostly a generic, straight-laced hero. Then, after Sonic Colors, probably to circumvent that problem and the result of a new writing team, they take his personality in the opposite direction and make his quirks more prominent, a cocky jock who almost rarely stops going on about how awesome he is and very rarely takes a threat seriously. Lost World seems to downplay this slightly by having his cockiness screw him (and the world) over, showing a more insecure side to his personality.
  • Celibate Hero: While he's aware of Amy's infatuation for him, he prefers to keep away from her when she acts on it. He's not interested in Rouge's flirting either.
  • Chekhov's Skill: He saves himself from one of Eggman's Death Traps in Adventure 2 by performing Chaos Control with a Fake Chaos Emerald. He learned the skill by watching Shadow.
  • Chick Magnet: To a downplayed extent in the main games. He ends up lampshading this in Sonic Battle: "Got enough girls chasing me as it is."
  • Chronic Hero Syndrome: Most bios state that he can never leave troubled people alone due to his sense of heroism and great kindness.
  • Clothes Make the Superman: His original storyline suggested that the source of Sonic's speed is his shoes, but this is never taken as canon, not even in other Sonic continuities from the early days — even the early Promo Comic dismissed that idea, and the game it was promoting said otherwise in the US manual! note  However, it is commonly accepted in several continuities (i.e. The Promo Comic, Adventures of Sonic, Sonic The Comic, Archie) that Sonic's shoes are designed to protect his feet from the friction and heat gained from going as fast as he does.
  • Commitment Issues: One interpretation of Sonic's aversion to romance is him being scared of settling down and giving up his free and adventurous lifestyle.
  • Competition Freak: Sonic hates losing races, as shown in Sonic Riders, but especially if someone cheats at it.
  • Conjoined Eyes: The standard design for himself and his friends.
  • Continue Your Mission, Dammit!: His impatience and snarky attitude towards the player for hold-ups shows in some of his idle animations. He'll even give you a Game Over if he's kept waiting too long in Sonic CD.
  • Cool Big Bro: To Tails. Cream also views him this way, and he could be considered one to Blaze as well, despite only being a year older than her.
  • Cool Plane: The Tornado. Which belongs to him, not Tails. Contrary to popular belief.
  • Cool Shades: Wears some in the Sonic Riders series.
  • Crouching Moron, Hidden Badass: Depending on the Writer, he can be somewhat bumbling and highly wacky in personality at times. His bouts of skill and heroism, however, are usually no less pronounced.
  • Cute Little Fangs: Was intended to have these from the very beginning until Sega of America had their final say on his design. However, if you look close enough at a few models, Sonic does have fangs. Sonic's Werehog form has prominent fangs as well.
  • Dance Battler: Many of his moves are based off of techniques seen in the likes of Break Dancing and Capoeira.
  • Dangerous Sixteenth Birthday: The entirety of Sonic Generations, where your present from your favorite villain is having your friends petrified in this side of White Space.
  • Dark Is Not Evil:
    • The Werehog, Darkspine, Violet Void, Purple Frenzy, Black Bomb, and "Dark Super" forms certainly look evil. However, they do not act evil nor do these forms carry out evil actions. Quite the contrary, actually. Some of them, however, make Sonic much more aggressive.
    • This is even touched upon a bit in Sonic Unleashed. Sonic is too heroic to give in to evil even when in his dark forms.
      Sonic: Even at night when I'm like this, I'm still myself. You must have been protecting me this whole time.
      Chip: No, you're the reason you haven't changed at all. You're too strong to lose yourself. You never give into the night, or darkness inside your heart.
  • Deadpan Snarker: Played straight in the video games and the comics, Sonic Chronicles, Sonic Storybook Series, Sonic Colors, and Sonic Lost World being some prime examples. Other portrayals remove the "deadpan" part. Sonic also had his moments of this in SatAM.
  • Defeat Means Friendship: With the exceptions of Amy, who was a Fangirl, and Tails, who either idolized him or was orphaned and bullied, almost all of his friends and allies had to be "befriended" before they joined up with him.
  • Demoted to Extra: There are a handful of games where he only makes brief appearances. Knuckles Chaotix only had him appear in the Good Ending. He was originally planned to be the star of the game, as proven by the Sonic Crackers prototype, but Sega of Japan was worried that the series brand image would've been hurt if Sonic headlined a game for the 32X add-on, which even they realized would be a flop, so they made Knuckles the games star instead, and had Mighty the Armadillo fill in for Sonic during the gameplay. And as mentioned earlier, he only makes an indirect cameo appearance via an item in Tails Adventure.
  • Depending on the Writer: Generally speaking, Sonic's personality is of the fun-loving guy who loves adventure, with something of an arrogant streak. The degree to which he leans in depends entirely on the continuity and adaptation. See Characterization Marches On above.
  • Destructive Savior: In Unleashed and parts of Generations, he causes a lot of property damage in his runs through the stages.
  • Determinator: Nothing slows him down for long.
  • Did You Just Punch Out Cthulhu?:
  • Does Not Like Spam: It is strongly implied in Sonic Unleashed that he does not like seafood, going by the extremely low EXP gainage after he is fed it.
  • Doesn't Like Guns: He openly admits in Shadow the Hedgehog that he "wouldn't be caught dead" utilizing guns and other firearms. He doesn't mind other people using them, though, so it's less of a dislike for them, and more a matter of him simply preferring to use his speed to fight.
  • Don't Call Me Sir: He clearly dislikes being referred to as "Master" by Shahra in Sonic and the Secret Rings and insists on being called by his name. He also dislikes being called "Mr. Sonic", as Cream and Elise find out.
  • Drop the Hammer: Gets his own version of Amy's Piko Piko Hammer if he is partnered with her in Sonic Advance 3.
  • Eagleland: Type 1. Take his snarky attitude, like of extreme/fun activities, and add in a "free spirit" cowboy personality, and you have Sonic in a nutshell. That his main colors are red, white, and blue helps.
  • Early-Bird Cameo: Sonic's first game appearance, predating his full fledged debut, was as a knick knack hanging inside the players car in the Sega arcade game Rad Mobile.
  • Easily Condemned: Clearly his reputation as the hero of Earth didn't stand for much in Sonic Adventure 2 considering GUN and the police were after him for a crime he obviously didn't commit, but that was due to them wanting to cover up the existence of Shadow, and Sonic made a perfect patsy for his crimes.
  • Establishing Character Moment:
    • Sonic the Hedgehog CD conveys who he is fairly well, showing his great acrobatics, difficulty traversing water, and running into Eggman's next plan with no idea what's in store for him. All without talking.
    • The intro to the original Sonic the Hedgehog also counts, as it simply has him do his signature finger wag to establish him as THE Mascot with Attitude.
    • Sonic Riders does this in its opening cutscene, quickly showing us how Sonic's Chronic Hero Syndrome, interest in extreme sports, and love of competition come together when he's given a new skill to master and a new rival to beat.
  • Even the Guys Want Him: Louie Montaine in Sonic Unleashed loves to go on about how hot he finds Sonic and lusts after his body after every successfully cleared mission he offers.
  • Everything's Better with Spinning: His primary method of attack, the Spin Attack, and its variations such as the Spindash and Homing Attack.
  • Experienced Protagonist: His rivalry's origins with Dr. Eggman have never fully been touched on so by the time Sonic 1 starts, he's already mixed it up with the doctor before.
  • Expressive Ears: They'll flick frequently when he's irritated with waiting (Sonic the Hedgehog 4's Idle Animation) and lie forward or sideways when he's asleep, disappointed, or feeling sick.
  • Extreme Omnivore: Eats anything, even moldy/rancid food (if Sonic Unleashed is anything to go by). Taken to the extreme in Sonic Colors when he absorbs Purple or Violet Wisps and morphs into a Purple/Violet monstrosity that chomps down on anything, even robots and other metallic objects.
  • Extremity Extremist: In battle, Sonic uses his feet more than his fists, combining this with Dance Battler.
  • Eye Color Change: Sonic's eyes are normally green, but when he goes Super Sonic, they turn red.
  • The Face: He's easily the most social of the three, and usually does all of the talking.
  • Face Palm: Does this fairly frequently.
  • Fatal Flaw: Sonic can get rather cocky and reckless in the face of danger, something that can often be exploited by his foes or lead to him making rather dangerous mistakes. How prominent this is varies from media to media, though it has cost him dearly at least once in just about every interpretation. This is taken to the highest degree in Sonic Lost World, when his recklessness causes the Zeti to break free from Eggman's control and become a larger threat than Eggman himself was, and later when his recklessness causes Tails to get kidnapped.
  • Fire-Forged Friends: Just about a number of characters started off as Sonic's enemies or opponents at one point or another, but they're now all invaluable friends/allies to him. The prolific examples include Knuckles, Shadow, Blaze, and Silver.
  • Flight: But only when he's Super Sonic.
  • Flying Brick: As Super Sonic.
  • Foil: He has quite a few. Notable examples include:
    • Dr. Eggman, being a scientist who wishes to rule through technology and totalitarian rule to Sonic's nature-loving idealism.
    • And back when they were still adversaries, Knuckles. Red Oni to Sonic's Blue, his strength to Sonic's speed, and his stationary lifestyle to Sonic's nomadic one.
    • Shadow. They're on very different ends of the Idealism vs. Cynicism scale and often come to blows because of it, and this is after Shadow's Heel–Face Turn in his own game. Before said Heel–Face Turn, practically every meeting between the two got rather... violent.
    • Blaze. Her introversion to his extroversion, her insecurity to his confidence, her fire to his wind. Though their relationship is much friendlier than the other examples, as Sonic tries to look out for her, and they mutually and openly respect one another.
  • Four-Temperament Ensemble: Phlegmatic
  • Friendly Rivalry: With Knuckles, as the two are now on good terms. This was a one-sided case with Shadow, who isn't interested in "friendly competition" as Sonic puts it in Shadow The Hedgehog. In the Mario & Sonic at the Olympic Games series, he also has a friendly rivalry with Nintendo's mascot Mario.
  • The Gadfly: He loves getting a rise out of his enemies, which is why he taunts them with such irreverence. This is proven in spades during his second encounter with Zeena in Sonic Lost World.
  • Genre Savvy: With the amount of times he hangs lampshades, he fits this to a T.
    Sonic (in Sonic Colors): Experience has taught me to investigate anything that glows.
  • "Get Back Here!" Boss: He's the final Dark Side story boss of Sonic Adventure 2 and insists on constantly running away from you, only stopping to fire off his signature move when there's enough space between Shadow and him.
  • Giving Someone the Pointer Finger: His trademark pose.
  • Golden Super Mode: Super Sonic, perhaps the second most famous variant after the Super Saiyans.
  • Good Is Not Soft:
    • His sealing away of Erazor during the ending of Secret Rings comes off as this, and would have been disproportionate if Erazor hadn't established himself as a truly irredeemable villain beforehand.
    • His mocking of the despairing Metal Sonic in the end of Sonic Heroes comes off as downright cruel and cocky, only justified by how monstrous Metal was beforehand.
    • Back in the very first game, you had the choice to either let Dr. Eggman flee or destroy the Eggmobile and watch him plummet to his apparent death. His ass-kickings of the doctor in the early mangas show that the second option was probably the canon one, though he has adopted more of a Friendly Enemy attitude towards Eggman in the modern age.
  • Gratuitous English: He started getting this when later games started to play up his 'tude more, as well as a nod to his international popularity; exclusive to the Japanese version, of course.
  • Green Eyes: Acquired these when he's in his Super form in the classic games, acquired these in his regular form from Sonic Adventure onwards.
  • Grind Boots: While everyone gains this ability by the time of Heroes, Sonic Adventure 2 sees Sonic sporting a pair of Soap shoes (in his trademark red and white colors), due to a deal between Sega and the Soap brand.
  • Heal Thyself: In Sonic Battle, his "Sonic Heal" ability is described as him using his supersonic speed to heal damage.
  • The Hero: In both senses. He's the main character of the series and the leader of "Team Sonic".
  • Heroic Safe Mode: In most modern incarnations, his response to most tragedies is to simply keep going.
  • Heroic Willpower: Present to a truly ludicrous degree. He can shrug off a mind-controlling monstrosity without even being aware of it. Curiously, this didn't work in Sonic Rivals 2. The Ifrit gains control of his mind (if you're playing as Tails) with ease.
  • Hero on Hiatus: When he temporarily dies in Sonic the Hedgehog (2006), he's out of commission and it's up to the other characters to retrieve the Chaos Emeralds to bring him back.
  • Holding Back the Phlebotinum: He never uses Chaos Control unless he absolutely has to.
  • Homing Projectile: He can turn himself into one using the Homing Attack.
  • Hot-Blooded: He's fairly passionate about saving the world from Eggman through-and-through.
  • Hurricane Kick: An R-Trigger trick in the Advance series.
  • I Am Not Weasel: He's... ahem... rather temperamental about being called a rat rather than a hedgehog throughout Sonic and the Secret Rings.
  • "I Am" Song: They call him Sonic. 'Cause he's faster than sound, he keeps on jumping around.
  • I Got Bigger: Sonic Generations confirms that "Modern" Sonic is the older version of pre-Sonic Adventure "Classic" Sonic.
  • "I Know You Are in There Somewhere" Fight: Throughout the whole series, he pulls this against Perfect Chaos in Sonic Adventure, and he tried this against Emerl/The Gizoid in Sonic Battle. In Emerl's case, it only partially worked, and the result? A sad ending.
  • Image Song: "It Doesn't Matter" and "His World". "Endless Possibilities" for his relationship to his were-hog form.
  • Impaled with Extreme Prejudice: Mephiles stabs him to death just to get an emotional response out of Elise and therefore unseal Iblis out of its person-shaped can. Thank goodness the Chaos Emeralds are capable of resurrecting the dead...
  • Improvised Parachute: He can actually use his cranial quills and hands to catch air like a makeshift parachute in order to make his descents through air slower in Sonic Unleashed and Sonic Colors.
  • Inexplicably Identical Individuals: Him, Shadow, and Silver all share the exact same height and weight of 3 feet and 3 inches, and 77 lbs.
  • Informed Attribute: His temperament. In most of the game manuals, he's described as being hot-tempered. This contrasts with the actual games, where he's simply cool and confident. Certain games such as Adventure 2 and Lost World show him losing his cool, albeit in a rather controlled and heavily provoked manner, probably leaning it more into Beware the Nice Ones than a defining attribute to the character. Certain alternate interpretations are more aggressive, though.
  • Informed Flaw: Word of God has stated that not having a full eight hours of sleep can severely affect Sonic's ability to function and also has a large impact on his running. This is never actually seen in the games, however.
  • In-Series Nickname: Rouge calls him "Big Blue" in Sonic Chronicles and Sonic Generations.
  • Intergenerational Friendship: He's almost twice the age of Tails.
  • Invisible Anatomy: He does not appear to have toes when depicted barefoot.
  • Involuntary Shapeshifter: In Sonic Unleashed. He can't stop his Werehog transformation from occurring at night or, in the case of the Wii version, in darkness within the Gaia Gates. He can temporarily revert back into normal form when in light or when exposed to light, but once he steps back into darkness, it's only a matter of time before he'll transform back into Werehog form. However, contrary to popular belief, Sonic did not consider the Werehog form a bad thing, and even enjoyed it in spite of it obviously handicapping his latent speed abilities, while giving him some new ones in turn.
  • Jack-of-All-Stats: Most of the cast is capable of using his signature moves (Spin Dash and Spin Jump) along with other abilities, but Sonic tends to be the most well-rounded in using his signature abilities.
  • Japanese Pronouns: "Ore".
  • Jerk with a Heart of Gold: He's not without his follies, but for the most part the Heart of Gold part mainly overshadows the Jerk part, in this case, since his jerkish tendencies only show towards his enemies and he is generally nice towards everyone else.
  • Karmic Trickster: In Sonic The Fighters, one of his throws is to take his opponent's weapon and use it on them in a very cartoony manner.
  • Kid Hero: He is only 15 years old in the present games, and was likewise this in the original games, until it was retconned to make him much younger during the Genesis years.
  • Knight in Shining Armor: What Amy sees him as. She's not too far off the mark though as Sonic is pretty selfless and some of his dislikes includes seeing people cry and any form of oppression upon others. He's also a bit of a Chick Magnet due to his kindness.
  • Large Ham: His personality is very boisterous and magnetic. When he makes the scene, he will be sure to let everyone there know (subtlety is not a prominent trait of Sonic). He also likes to quip and taunt when he's in the middle of a skirmish, probably rivaling Peter Parker in terms of how much snark he dishes out.
  • Last Second Showoff: All the time, almost as often as when he's a Leeroy Jenkins.
  • The Leader: Headstrong type for all of Team Sonic and Charismatic type for the cast of heroes as a whole.
  • Leeroy Jenkins:
    • Varies according to the story. Even at his mildest, Sonic has no patience for waiting around or discussing tactics. Other than the Sonic Storybook Series , he rarely, if ever, gets called out on this even if it's invoked.
    • This is played straight in Sonic Lost World, however, when, despite Tails' warnings, Sonic kicks Eggman's conch away. Said conch was the only thing keeping the Deadly Six under his control, and they promptly attack everyone in sight, which prompts a retreat. Tails and Eggman do, in fact, call him out on it.
  • Leitmotif: Sonic The Hedgehog Title Theme overall and for Classic Sonic, Live & Learn for Modern Sonic are the most recurring. He also gets a new theme song every other game (see Image Song above for examples).
  • Le Parkour: Mostly shown off as Scripted Events or as cutscenes in most 3D games, it becomes a full-fledged game mechanic in Sonic Lost World, which gives him the ability to run and jump along walls and celings, complete with Speed Echoes.
  • Limited Wardrobe: Is virtually never seen wearing anything save White Gloves and his pointy buckled shoes in every Sonic continuity. The only exception was his Soap Shoes in Adventure 2, after which he just went back to his traditional outfit.
  • Loveable Rogue: While generally having a strong sense of justice, he is willing to go against the law, especially if they are after him.
  • Magic Pants: Applies to both the Werehog and Darkspine forms. Werehog loses his gloves, then gains them back upon transforming back into normal form, whilst Darkspine loses his shoes, socks, and gloves and gains them back within a split second of turning back into normal form.
  • Magnetic Hero: Very easily makes friends and allies, even from former enemies. There are times when he doesn't try to make friends with anyone, he just does.
  • Mascot with Attitude: The Trope Maker.
  • Master Swordsman: In Sonic and the Black Knight. Despite probably never using a sword before in his life, he manages to slay a dragon with just a training sword. And when he picks up Caliburn, he goes on to defeat the three Knights of the Round Table and King Arthur himself.
  • The McCoy: He definitely fits this to a "T" among Team Sonic in the games.
  • Meaningful Name: He is called Sonic for a reason.
  • Mellow Fellow: Certain interpretations convey him as thoroughly easy going and hard to break, rarely holding grudges against even antagonistic characters. Other interpretations are subverted as he can be more Hot-Blooded.
  • Mighty Glacier: In his Werehog form, he loses most of his trademark Super Speed in exchange for Super Strength and stretchy arms.
  • Mirror Boss: Acts like this against Shadow in Sonic Adventure 2 during the first boss fight against him. He does it again in the final Dark Side boss, with the exception of him having access to his Sonic Wind move whilst Shadow doesn't have his Chaos Spear.
  • Miscarriage of Justice: He was sent to prison in Sonic Adventure 2 so that GUN could use him as a patsy for the crimes of Shadow, whose existence they wanted to keep covered up.
  • Monochromatic Eyes: His Darkspine form has them.
  • Morphic Resonance: All of Sonic's forms share common design aspects to the 'normal' form. The Wisp forms also share yellow, pupiless eyes, ears, and spiky protusions (except for Violet Void form, which has only the eyes and mouth, and Blue Cube form, which only has the eyes and inner ears). All of these design aspects resemble the normal form's eyes, ears, and quills to a great extent.
  • Mr. Vice Guy: Some versions of him are very prideful. He sometimes prioritizes his beauty-sleep a little too highly, as well but as noted, he's still a good person.
  • Multiple-Choice Past: Outside of a brief mention of his birthplace , he's never really been given an official backstory in the games.
  • Mysterious Past: The only things ever revealed about Sonic's past is that his rivalry with Dr. Eggman predated Sonic the Hedgehog 1 and that he was born on Christmas Island.
  • The Name Is Bond, James Bond: Somewhat reversed in his Catch Phrase "I'm Sonic; Sonic the Hedgehog!"
  • Nature Lover: Stated to have an appreciation for the beauty of nature.
  • Nerves of Steel: For the most part, at least in the games.
  • Nice Guy: Probably the best example in the series short of Tails (except for Sonic Chronicles and Fleetway's Sonic the Comic), as Sonic is often noted for his compassion and selflessness.
  • Nice Job Breaking It, Hero: There are a few examples of Sonic unintentionally causing a lot of mistakes.
    • In Sonic Unleashed, his arrogance and fixation with belittling Eggman instead of paying attention to what he was doing was ultimately the catalyst of the game's plot and his Werehog transformations.
    • In Sonic Colors, when he destroyed Rotatatron/Globatron, an arm got lodged into a nearby structure, which turned out to be part of the mind control cannon. When Eggman tried to fire it, the cannon backfired. The resulting energy created two things: a Nega Hyper-Go-On black hole that consumed the amusement park and, if evidence is correct, the primordial essence known as the Time Eater. Basically, Sonic caused Sonic Generations to occur by destroying the first boss of Colors.
    • In Sonic Lost World, he's pretty much responsible for the Deadly Six betraying Eggman and attempting to conquer the world for themselves by disposing of the Cacophonic Conch Eggman was using to control them without even bothering to find out what it was. Then he does it again, this time, causing Tails to be trapped inside a capsule and turned into a robot.
  • No Guy Wants to Be Chased: Especially if the chaser's name is Amy Rose.
  • Not the Fall That Kills You: He ends up walking away from those falls with no injuries at all. This makes sense, as he can survive collisions at supersonic speeds, far faster than his terminal velocity would be.
  • One-Dimensional Thinking: As if to parallel his bullet like speed, Sonic kindof has a one-track, arrogant mind, and when he sets his mind on a goal, he will not rest until it is carried out, and this can make him do some very impulsive, foolhardy stuff. This "smash first, ask questions later" mentality ends up biting him in the rear hard in Sonic Lost World, when he accidentally makes Eggman's newest minions an even bigger threat than before by accidentally freeing them from Eggman's control.
  • One-Hit-Point Wonder: A notable handicap of his—if it weren't for the rings protecting him, he'd have been roadkill years ago. This can be chalked up to Gameplay and Story Segregation however; Sonic has often been shown to be able to take a reasonable amount of punishment before going down, and sometimes the attacks he goes through are reasonably powerful enough (or relevant to the plot) that it mandates him taking lethal damage, even if he had a ring or his Super Sonic form on hand—such as two occasions in Sonic 3 note  and one point in Sonic 2006.
  • One-Man Army: Technically, he's a "One Hedgehog Army". Wherever he runs, expect lots of trashed robots in his wake. Don't believe it? Watch the prologue to Unleashed.
  • One True Love: According to the "Test of Love" in Sonic '06, his soulmate choices for life are narrowed down between Amy and Elise.
  • Our Ghosts Are Different: After Mephiles kills him in '06, his ghost/spirit appears in the form of a gust of ethereal blue wind that only Princess Elise can detect.
  • Our Werebeasts Are Different: Sonic the Werehog in Sonic Unleashed. Even the "werehog" term was originally coined by the fans, and Sega just shrugged and went, "eh, why not?"
  • Out of Focus: This actually happened to him in a certain period of time in the series, despite the series named after him. In Sonic Adventure 2, Shadow was the character with more plot focus, backstory, and Character Development in that game. This continued through Sonic Heroes and into Shadow the Hedgehog, where Shadow actually displaced Sonic as the main character as well as Sonic '06, where both Shadow and the new character Silver displaced Sonic.
  • Papa Wolf: He serves as one to Emerl in Battle. Earlier on, he was more of a Big Brother Mentor to Emerl, but as time progressed... He nearly has a Freak Out when Emerl is on his death throes.
  • Parental Abandonment: In most incarnations, his parents (or lack thereof) are not referenced even once.
  • Personality Powers: He is one free-spirited wanderer with Super Speed powers. He also has some level of aerokinesis, which again, reflects his carefree nature and inability to stayin one place for long.
  • Pinball Protagonist: He was afflicted with this horribly in Sonic the Hedgehog (2006), in which the most influential roles are delegated to Shadow and Silver and he barely gets anything of noteworthiness done in the grand scheme of the story.
  • Pint-Sized Powerhouse: 3'3'' tall, 77.2lbs in weight, and yet he can defeat monstrosities like this with only the shoes on his feet.
  • Power of the Void: He becomes a living, moving void in Violet Void form that consumes nearly anything he comes across and becomes bigger in the process.
  • Power Strain Blackout: Overuse of his Super form can cause this due to the amount of energy required to sustain it.
  • Pragmatic Hero: Very much this in Sonic and the Black Knight. He was fully willing to allow The Grand Kingdom to come to an end rather than allow Merlina to use her magic to make it eternal.
  • Protagonist Without a Past: Aside from his birthplace being Christmas Island, nothing is known about his past.
  • Pride: He's fully aware of his Super Speed, and he's proud of it.
  • Promotion to Parent: Most (if not all) incarnations where Tails isn't living independently has Sonic being the one who takes Tails under his wing.
  • Punny Name: His Super Sonic form.
  • Razor Wind: His Sonic Wind attack, as depicted in Sonic Adventure 2.
  • Real Men Wear Pink: One of his hobbies includes admiring flowers.
  • Red Oni, Blue Oni: In addition to the aforementioned above, he's also got this dynamic with likes of Shadow, Blaze, Dr. Eggman. (Red to the former two, Blue to the latter)
  • Ridiculously Cute Critter: Especially Classic Sonic.
  • The Rival: Sonic has many of them. The current primary ones are Shadow and Jet. Knuckles once served this role, but he has since grown out of it.
  • Rivals Team Up: With Knuckles, then Shadow, then Blaze, and then Silver.
  • Royals Who Actually Do Something: At least, as far the games' version of the Blue Blur is concerned; according to Sonic and the Black Knight, he's the genuine King Arthur.
  • Rude Hero, Nice Sidekick: While he's nowhere near as rude, Sonic is the cocky and snarky hero in contrast to Tails' level-headed and mild-mannered personality.
  • Running Gag: He tends to fall flat on his face when falling from great heights from Sonic Adventure onwards.
  • Scarf of Asskicking: Sports a brown one, along with Handwraps of Awesome, in Sonic Boom.
  • Screw the Rules, I'm Doing What's Right: Oh so much in Sonic and the Black Knight. He'll willingly become a king slayer to do what is right. Also has shades of this in Sonic X.
  • Screw This, I'm Outta Here!: If he is left still for three minutes in Sonic CD without doing anything, he'll say "I'm outta here" and leave, resulting in a game over.
  • Ship Tease: Has a lot of these.
    • He gets this with Amy. In Sonic Unleashed, Sonic feels depressed after Amy didn't recognize him as a werehog, thinking she mistook him for someone else again. Also, the dialogue options in Sonic Chronicles, you can be seen by treating Amy nicely - before the attack on Nocturne, She'll ask to speak with Sonic privately.
    • Also, depending on the dialogue options in Chronicles, Sonic/Rouge is hinted at if you're sarcastic with Amy.
    • Shares one with Blaze in the end of Sonic Rush. He and Blaze have a long stare at each other and are trying to hold on to each other as long as possible before they get separated — Sonic's holding on with both hands. It's as if they're both reluctant to part ways.
  • Shout-Out: Collect all seven Chaos Emeralds and at least 50 rings, and jump into the air. Sonic will turn into Super Sonic! His fur will turn gold, his eyes will turn green (or red) and... wait, haven't we seen this before?
  • Showy Invincible Hero: Sonic Colors and Sonic Generations are very good examples. There is no question Sonic will win, the only matter is how will he win, how cool he looks when he wins, and how much fun the player will have when he wins.
  • Shut Up, Hannibal!: Besides snarking at his opponents, he can deliver these on occasions:
    • In Sonic Adventure 2, he gave one to Shadow, saying that he will make him take back those words about him "not being good enough to be his fake".
    • There are several of these in Sonic and the Black Knight when Sonic confronts Merlina, who explains that the only way to save Camelot from its tragic fate is to use the power of Excalibur's Scabbard and the Underworld to make it eternal, only to have Sonic reply "What good is a world that goes on forever!?" The conversation even ends with this great exchange between the two characters:
    Merlina: My sorrow at its ruin runs deeper than the depths of the underworld... do you not understand?
    Sonic: No! And I don't want to!
  • Signature Move:
    • The Rolling Attack in its many forms such as the Spin Dash, the Homing Attack and the Hurricane and Rapid Strikes from the old mangas, even though most of the other characters can roll around too. In Sonic Adventure 2, Sonic Wind was his special attack.
    • The Sonic Boost has become his signature move as of the Modern era games, where he even lacks the ability to do his old spin dash.
  • Sigil Spam:
    • Sonic makes a lot of cameo appearances in other Sega games. He even appears in the Sega CD and Sega Channel boot up. He is their mascot, and they want you to know it.
    • In-universe, you'll see Sonic's mug frequently pop up on objects like the 1-up monitors and the Sonic Item from Tails Adventure, to mugshots on casino slot machines. Sonic the Fighters even has a Sphinx with his face carved onto it!
  • Sleepy Head: He appears to have a habit of momentarily dozing-off in idle animations. He is also often seen napping on a tree branch or Chris' roof in Sonic X.
  • Slide Attack: Occasionally used as one of his rare non-spinning means of melee.
  • Small Town Boredom: One official source states that Sonic only began exploring because he was bored with his birthplace, Christmas Island.
  • Smarter Than You Look: Especially considering some of his earlier portrayals. He is far from stupid.
  • Smug Super: While how much one may vary between different media, one thing that's constant is Sonic's ego.
  • Spirited Competitor: Being the cocky guy he is, he loves to race others in order to prove the he is faster than them.
  • Sprint Shoes: The first European/North American game manual mentioned that Sonic's speed comes from his power sneakers, although this bit of info is never taken as canon. However, video monitors in the classic games award Sonic with power-up shoes that allow him to go even faster than normal.
  • Static Character: Despite being the main character, his characterization has actually evolved the least out of everyone else in the entire series. This is justified by the fact that he's a mascot, and most of the Character Development of most of the cast generally plays off of him, such as Tails going from overly dependent on him to being an independent hero in his own right, or Blaze making friends with him. In terms of actual depth, he's just as much of a Rounded Character as most anyone in the series.
  • Strong as They Need to Be: Depending on the game or the situation, Sonic can go from outrunning planes and missiles to be being unable to catch Eggman, an overweight human, when the latter is running on foot.
  • Super Drowning Skills: In most of the 3D games. He instead has Walk, Don't Swim in 2D.
  • Super Mode:
  • Super Speed: He's called "Sonic" for a reason, Its basically his trademark. (His top speed has never been canonically established, though he's shown to be capable of breaking the Sound-Barrier whenever he kicks into high gear). For the record, Sonic X pins him at 600 mph, which is essentially the far limit of subsonic speeds.
  • Super Strength: Though it arguably draws from his speed more than anything, he can ram through cars, robots, and rock walls and not slow down. The Sonic Boost especially shows this.
    • While the games don't show much of it, Sonic X and Sonic the Hedgehog: The Movie both show him preform clearly superhuman feats of strength, like pushing a giant robot's hand off of him without using any momentum, or his fight with Metal Sonic causing huge fissures in the ground and causing a mountain sized stalactite to fall off a floating continent.
  • Swiss Army Hero: And then some! Especially in Sonic Colors. He can turn into a laser, cube, black hole, rocket, explosion-generator, organic Hover Tank, ball of spikes, drill, and a purple monstrosity that eats and grows in size with each eaten object.
  • A Taste of Defeat: Naturally, no villain has stopped him from saving the world, but he has had his ass handed to him on rare occasions. Eggman managed to outwit him in his super form at the start of Sonic Unleashed, for example, and Silver just plain humiliated him, twice, in Sonic '06..
    • In more petty competition, Jet canonically beat Sonic in the World Grand Prix finals in the first Sonic Riders (albeit by cheating). This also marks one of the few times Sonic is genuinely enraged.
  • Teleporters and Transporters: Has the ability to teleport by using Chaos Control in-tandem with a Chaos Emerald, whether it's fake or real.
  • Teleport Spam: He loves doing this in the last Dark Side Story boss in SA2 if you get too far ahead of him.
  • Thrown Out the Airlock: Eggman tries to murder him by doing this. Fortunately, he learned how to use Chaos Control just in time.
  • Time Master: Using Chaos energy, he can warp time and space, but is not as proficient as Shadow, nor does he use these abilities very frequently.
  • Too Important to Walk: Well, he's much more important to "run".
  • Took a Level in Badass: He defeats Perfect Chaos in Sonic Generations in normal form without resorting to transforming into Super Sonic.
  • Took a Level in Jerkass: Sonic Chronicles, if you select the more snarky options in a Dialogue Tree.
    • Another example is Sonic Underground, where he rather comes off as egotistical.
  • Tornado Move: In Sonic Rush, in the boss fight against him as Blaze, one of his attacks is him spinning around while airbore, which creates a massive vortex that sucks her in. The Blue Tornado in Sonic Heroes does the same thing, but on a much smaller scale.
  • Totally Radical: He dips into this at times in his modern depiction.
    • This is actually averted in Colors, where he actually gets to use relatively modern slang like "epic".
  • Touched by Vorlons: He gains the ability to shapeshift into various forms by fusing with Wisps temporarily.
  • Trademark Favorite Food: Chili dogs in most adaptations, and later, including the games.
  • A Tragedy of Impulsiveness: In Sonic Lost World, he disposes of the Cacophonic Conch Eggman was using to control the Deadly Six without even bothering to find out what it was or what it did, which enables the Deadly Six to turn on Eggman and usurp his plans and operations, making them a bigger threat than before.
  • Transformation Trinket: Chaos Emeralds, Super Emeralds, World Rings, Sacred Swords, and Wisps. All of them are catalysts for his transformations.
  • Troll: Sonic LOVES to get a rise out of his enemies.
  • Tsurime Eyes: As Super Sonic, and in his Werehog form.
  • Turn the Other Cheek: Going hand-in-hand with Fire-Forged Friends and Magnetic Hero, Sonic's kindness and compassion are matched only by his capacity for forgiveness. Many of the friends he made, such as Silver and Shadow, once tried to kill him, but he never holds it against them.
  • Übermensch: Sonic stated in Sonic and the Black Knight that he'll fight for what he believes in and he doesn't care whether that means he's the hero or the villain. He and others also describe him as being "free like the wind", and he makes it clear that he both dislikes being restrained and dislikes it when others are oppressed, too.
  • Unable to Cry: In the majority of media Sonic has been featured in, he's remarkably stoic and does not show sadness, loss, and/or disappointment in the form of tears.
    • The latter continuities were however asked to keep said aversions toned down, suggesting it is to higher ups rather uncharacteristic for him to cry in most interpretations. The fact that he dislikes crying may support it.
  • The Unfettered: A mild version; he wouldn't hesitate to put his life on the line for a friend, but he also wouldn't want to endanger his friends and is very protective of them.
  • Unstoppable Rage: Darkspine Sonic in Sonic and the Secret Rings doesn't stop expressing his hatred, rage, and sadness until Alf Layla Wa Layla goes down.
  • Used to Be More Social: In one of the dialogue options in Sonic Chronicles, his friends point out on how he hasn't kept close contact with them for two years after defeating Eggman together.
  • Vitriolic Best Buds: In addition to Knuckles, he kind of has this with Shadow to some extent.
  • The Voiceless: His younger self is this in Generations.
  • Voluntary Shapeshifting: Upon absorbing a Wisp, he can choose to make use of its Hyper Go-On power in order to change form.
  • Walk, Don't Swim: Another of Sonic's major weaknesses is that he can't swim, so when he gets in water, he merely floats down or runs and jumps very slowly in it. Often, falling into a large body of water will also result in him immediately sinking to his death. Some continuities, such as Sonic X, upgrade this into a personality flaw, where Sonic is literally terrified of being surrounded by or falling into large bodies of water. Apparently, the reason Sonic has this weakness in the first place is because Yuji Naka, at the time the first game was made, erroneously assumed that hedgehogs were incapable of swimming, so he incorporated this into the gameplay.
    • In the swimming event of Mario And Sonic At The Olympic Games, he manages to work around this weakness by wearing a lifejacket.
  • Walking the Earth: When not saving the world, he's always running from place to place, but he'll immediately rush to the scene if someone is up to no good.
  • Wall Jump: First appeared in an unconventional form in Sonic Heroes, where it's used to cross chasms with walls on either side. Starting in Sonic Unleashed, he has a more conventional Mario-style Wall Jump.
  • Weaksauce Weakness: He can't swim.
  • The Worf Effect: Though he's pretty much an Invincible Hero, there are some occasions where he gets beaten by more powerful characters.
    • He gets punched out of his super form by Knuckles with one punch, in his debut!
    • Sonic and his friends all had trouble defeating Chaos, as the first villain ever.
    • Also against Shadow in his solo game, if the player chooses to go against him.
    • He also gets beaten by Silver twice, much to the point where he had to be saved by Shadow the second time, and to run away in the mean time.
    • Several times by Eggman when inside of some giant robot.
  • Who Wants to Live Forever?: Not him, as Sonic and the Black Knight proves. Sonic is apparently inclined to live life to the fullest in the time he has and stresses to others that they should do the same.
  • Why Did It Have to Be Snakes?: He occasionally mentions that he doesn't like water in games such as Sonic and the Secret Rings and Sonic Colors DS, as well as the various comics and animated series he features in. Considering that the drowning music so often heard in underwater stages is considered to be the most frightening thing in the entire franchise, this is entirely justified.
  • Willfully Weak: It's implied through Cutscene Power to the Max and certain scripted events that Sonic holds back his full speed. Whether it's to challenge himself or if it tires himself out to use his full speed is uncertain.
  • With Friends Like These...: Often with Knuckles in the earlier games. Also with Shadow to some extent, and let's not get started with Jet.
  • Would Hit a Girl: He's fully willing to engage in a fight against Blaze in Sonic Rush when Blaze picks one with him and also fought Amy, Cream, and Rouge in Sonic Heroes. He also had no compunctions about attacking Merlina when she revealed her plans as the Dark Queen in Sonic and the Black Knight. In all cases of course, it applied as self defence.
  • Wrong Genre Savvy: In Sonic Lost World, he disposes of Eggman's Cacophonic Conch, telling the doctor outright that it's never a mistake to "throw his toys away." Unfortunately, in this case, it was a mistake: the conch was a Restraining Bolt that Eggman was using to control the Deadly Six, who waste no time in usurping Eggman's Badniks and turning on him..
  • You Gotta Have Blue Hair: You Gotta Have Blue Quills.

    Miles "Tails" Prower 
http://static.tvtropes.org/pmwiki/pub/images/chara_tails_6557.gif

"I've changed a lot since I started hanging out with Sonic, but I can't depend on him forever. I know I can do this by myself!"

Debut: Sonic the Hedgehog 2 note 

Voiced by: Hekiru Shiina (Japanese, OVA), Kazuki Hayashi (Japanese, 1998), Atsuki Murata (Japanese, 2000-2002), Ryo Hirohashi (Japanese, 2003-present), Christopher Stephen Welch (English, AoStH), Bradley Pierce (English, SatAM), Chris Turner (English, Sonic Christmas Blast), Lainie Frasier (English, STH: The Movie), Corey Bringas (English, 1999-2001), Connor Bringas (English, 2001), William Corkery (English, 2004), Amy Palant (English, Sonic X, 2005-2010), Kate Higgins (English, 2010-2013), Colleen O'Shaughnessey (English, 2014-present)

Sonic's young sidekick: a small fox who can use his unique twin tails to fly. Despite his young age, he's a reliable and dependable ally to Sonic. In later games, he's come into his own as a genius inventor that even rivals Eggman. His real name is Miles Prower, and he grew up as an orphan, ostracized because of his twin tails. One day, he noticed Sonic's running by and was so awed by his speed, he tried to catch up using his tails. Sonic didn't pay the young fox any attention, but witnessing how he nearly caught up with him impressed him enough to take him under his wing and give him his well known nickname. Together, they foiled Eggman's latest scheme on Westside Island and the two became nearly inseparable.

Ever since their first meeting, Tails has tried his hardest to be the best person he can for Sonic's sake, often times by mimicking him. Humble, docile, and good-natured with mechanical prowess that can potentially rival Eggman's, but he never thought it was much of a big deal.

  • Happily Adopted: Some continuities give him the backstory of being adopted and raised by Sonic himself.
  • Heartwarming Orphan: He has no known parents, but is often described as an orphan in certain alternate media.
  • Heli Critter: He's probably at least a Trope Codifier.
  • Horrible Judge of Character: He'll believe someone if they say they aren't evil, no matter what prior experiences he's had with them.
  • Humble Hero: He's done his fair share of heroics but is far too modest to really take credit, in sharp contrast to Sonic.
  • Hypercompetent Sidekick: Games continuity only. Tails has an absurd number of useful skills, and can do nearly anything Sonic can do and more.
  • Hyperspace Arsenal: He doesn't use it often, but he has a ton of stuff that can appear out of nowhere, especially in Tails Adventure.
  • I Love Nuclear Power: At least in a few alternate continuities, it's been theorized that his mutation is the result of toxic waste dumped by Dr. Robotnik.
  • ImageSong: "Believe in Myself"
  • Informed Attribute: Many modern bios refer to him as a "hyperactive fox boy", despite his Keet-like attitude fading considerably over the years in favor of him becoming rather mellow and serious minded character.
  • Innocent Blue Eyes: They really bring out his childlike innocence.
  • Innocent Prodigy: It varies from game to game, but Tails is just a kid who happens to be extremely intelligent for his age. He sometimes joins in on Sonic's taunting, but also wises up faster than his big bro as well.
  • Intergenerational Friendship: Most of his friends, all of his close friends, are quite a bit older than him.
  • Jack-of-All-Stats: Outside of platformers, this is Tails' usual role. For example, in Sonic Battle, he has slightly above average speed and defense; with average attack power. In general, he tends to be faster but weaker than Knuckles; and slightly slower but stronger than Sonic.
  • Japanese Pronouns: "Boku".
  • Keet: Earlier media such as Sonic SatAM portrayed Tails as a much more hyperactive and immature character. As modern interpretations focused on his technogeek persona more and more, this trait faded, to the point that Tails is almost the most mellow and sensible-acting character of the team.
  • Kid-Appeal Character: The very first one of the series, he's often recommended for beginners due to his flying abilities in the 2D games.
  • Kid Sidekick: He's almost twice as young as him to boot.
  • The Kirk: Overlapping with The Spock at times. Tails is generally the most level-headed of the three.
  • Kitsune: He doesn't have the magic powers associated with Kitsune, but he has the intelligence and multiple tails.
  • The Lancer: In more recent games, he acts as a more humble and reasonable foil to the cocky and impulsive Sonic.
  • The Leader: Tails has been portrayed as the leader of Sonic's merry band recently due to his status as The Smart Guy, especially evident in Sonic Chronicles.
  • Little Professor Dialog: He can speak some big words for his age and is generally the one to piece together and explain things. (Also when doubled over as the Exposition Fairy)
  • Lovable Nerd: Very nerdy, but also very adorable.
  • Made of Iron: Even without counting his invincibility in the 2-player mode of the older games. Tails has been shot with lasers and crashed planes multiple times, but the worst he's ever been hurt is being dazed for a few minutes.
  • Masculine Girl, Feminine Boy: The Feminine Boy to Amy's Masculine Girl.
  • Meaningful Name: Miles Prower fits in with Sonic's name, referring to velocity.
  • Motor Mouth: Not as much as Marine or Omochao, but often with Techno Babble.
  • Mr. Fixit: He's a mechanic and maintains planes pretty well. Sonic Lost World also showed him fixing Cubot's malfunctioned voice chip and reversing the effects of Eggman's machine.
  • Mr. Vice Guy: Tails is usually incredibly lucid and intelligent, but sometimes his childishness seeps through, making him naive or huffy. He's also sometimes a bit over fixated with machinery, at the cost of his attention span.
  • Multiple-Tailed Beast: Being based on a Kitsune, it's to be expected.
  • Nice Guy: One of the nicest and most mild-mannered of the cast.
  • Non-Action Guy: He's made this in Unleashed, Colors, and Generations. Subverted in the 3DS release of Generations. He and his younger self attack Eggman head-on in the end, allowing the Sonics to go Super and finish it up.
  • Noodle Incident: One has to wonder how Tails was able to make a TV out of paperclips, and reprogram a computer with detergent & a toothpick, as was mentioned in Sonic Lost World.
  • Number Two: Often cited as Sonic's right-hand man and the most likely to tag along in his adventures. He even sometimes takes over in Sonic's absence.
  • One-Man Army: In Tails Adventure, it's seen that he can easily be one of these.
  • Only Known by Their Nickname: To the point where most people didn't think he had a real name.
  • Only Sane Man: In Sonic Battle, at least.
  • Out of Focus: PlayedWith. He's nowhere near as prominent as he once was and he's rarely a playable character nowadays, but he continuously makes appearances in the plot and is just as much apart of the action as Sonic.
  • Ping-Pong Naïveté: Has astonishing technical abilities, but often has the disposition and naïveté of a child. This lessened significantly around Sonic X and Sonic the Hedgehog (2006), but started to trickle back in with Colors and Generations.
  • Pint-Sized Powerhouse: 2'7" tall, weighs 44 lbs (and look at the size of his tails and tell me that they aren't most of that). He's just as capable of demolishing robots as Sonic is, and at some points lifts four times his own weight and breaks rocks with his bare hands.
  • The Pollyanna: He honestly believed that Eggman had truly reformed in Sonic Colors, even though it's clear that he didn't.
  • Prehensile Tail: Tails shows this ability for the first time ever in Sonic Lost World, when he grabs the toothpick stuck in Zomom's sandwich to save himself from being robotified.
  • Punny Name: Miles Prower = miles per hour.
  • Ridiculously Cute Critter
  • Rude Hero, Nice Sidekick: He's the mild-mannered sidekick to the snarky yet compassionate Sonic.
  • Science Hero: He often uses his smarts and various gadgets to aid him and his friends save the day.
  • Sesquipedalian Loquaciousness: Can slip into this sometimes. (Sonic Riders hosts one of his most famous examples)
  • Shorter Means Smarter: Justified in that he is much younger than most of the cast.
  • Sidekick: To Sonic.
  • Single Specimen Species: Probably; if the cartoons are anything to go by, Tails is the only two-tailed fox there is.
  • Sleepy Head: Starts yawning in his idle pose in the classic games and in Sonic Adventure, and falls asleep in Sonic Advance 2 and Sonic 4: Episode 2.
  • Shock and Awe: His most commonly used element, as used in Sonic Heroes and Sonic Battle.
  • The Smart Guy: Tends to be more far more rational and analytic than his peers.
  • Super Mode: Super Tails, which has only appeared in Sonic 3 & Knuckles so far. Unlike the rest of the characters, he needs the Super Emeralds rather than the Chaos Emeralds to achieve super form. According to Word of God, this is due to his inexperience and young age. He even has four Super Flickies to attack enemies for him.
    • As of the 2013 re-release of the original Sonic the Hedgehog, Tails can go super with just the Chaos Emeralds, but only if a hidden setting is used to make all seven show up.
    • Also has a different Super Mode used in Sonic Heroes. There is, however, quite a bit of confusion as to whether or not it's actually supposed to be Super Tails or not. The only visual difference is a golden shield surrounding him, but he has all the normal abilities associated with a Super form. Adding to the confusion is that Tails' and Knuckles' super forms in previous games only included them glowing, with no visual changes whatsoever.
  • Super Speed: His ability to move fast enough to keep up with Sonic impressed him enough that he took Tails as his sidekick. Notably, Tails has actually managed to outrun Sonic a few times (in Sonic Adventure and Sonic Colors).
    • It's not always noticeable, but Tails has been shown to be very fast even without using his tails - On par with, say, Amy or Espio, who are classified as Speed characters.
  • Super-Strong Child: Although this can also apply to the other small children in the series, Tails is the only one consistently portrayed as being deceptively strong. Several games show him able to lift more than his own weight without hindering his flight (possibly up to ten tons if Tails' Skypatrol is any indication), breaking through rocks with his bare (or gloved) hands, and, of course, tearing through robots as a ball.
  • Tagalong Kid: Subverted. While he does meet Sonic by initially following him, he ends up proving useful and Sonic decides to keep him around. From then on, he's become one of Sonic's closest allies.
  • Tail Slap
  • Taking the Bullet: Does this a few times — He's back up within a few seconds.
  • Tareme Eyes: Has the softest, droopiest eye shape of the cast — even more so than Cream.
  • Took a Level in Jerkass: Like with Knuckles, same thing happensto him in Sonic Lost World. He seems to have adopted a smug, obnoxious, and whiny attitude. He calls out Sonic for being interested in teaming up with Dr. Eggman to fight against the Deadly Six, even though he was perfectly fine with it before. The worst part is that he never owns up to it at the end of the game. YMMV though.
  • Trademark Favorite Food: Mint candy.
  • Undying Loyalty: A consistent with almost every interpretation of Tails is that he is always by Sonic' side.
  • Voice for the Voiceless: His classic self acts as this for Classic Sonic in Sonic Generations.
  • Walking the Earth: He seems to spend time either doing this with Sonic, or in one of his multiple workshops.
  • "Well Done, Son!" Guy: Sonic's approval is very important to him, to the point where if he feels he doesn't have it makes Tails very upset. Fortunately, Sonic is already plenty proud of the young fox.
  • Weak, but Skilled: Classified this way in Mario & Sonic at the Olympic Games
  • Why Did It Have to Be Snakes?: He's afraid of lightning in some versions, especially in the OVA.
  • Wise Beyond Their Years: An eight-year-old who is able to fly a plane and make some cool gadgets. Also, he's often the mediator between Sonic's friends.
  • Worthy Opponent: To Rouge in Sonic X.
  • Would Hit a Girl: He has no problem challenging Rouge in battle in Sonic X. He loses.

    Knuckles the Echidna 
http://static.tvtropes.org/pmwiki/pub/images/chara_knuckles_2834.gif

"I'll probably be on this floating island forever, guarding the Master Emerald again. I may not know the whole story behind this, but perhaps it's better that way. I'm at peace once more."

Voiced by: Yasunori Matsumoto (Japanese, OVA), Nobutoshi Canna (Japanese, 1998-present), Bill Wise (English, STH: The Movie), Brian Drummond (English, Sonic Underground), Michael McGaharn (English, 1999), Ryan Drummond (English, 2000), Scott Dreier (English, 2001-2004), Dan Green (English, Sonic X, 2005-2010), Travis Willingham (English, 2010-present)

A red echidna from Angel Island, and guardian of the Master Emerald. He was first introduced as an antagonist in Sonic the Hedgehog 3 and Sonic & Knuckles, having been told by Eggman that Sonic and Tails intended to steal the Master Emerald. Halfway through the game, Eggman betrays Knuckles and steals the Master Emerald himself, which forced Knuckles to accept Sonic & Tails help in getting it back. Afterward, Knuckles would then be one of the duo's chief allies in fighting Eggman, but his guardian duties keep out of the action most of the time. Not much of his past was known, but that changed with Sonic Adventure which fleshed out his background quite a bit. Turns out, Knuckles is the last of the echindas after they were wiped out for attempting to use the the emeralds and desecrating the shrine(And injuring numerous Chao) which the angered the at the time guardian Chaos. Afterward, the piece of the shrine became Angel Island.

If Sonic is like the wind, then Knuckles is like the mountain; stern and unmovable. So naturally, they tend to butt heads, but do get along occasionally. Because of spending most of his life on a secluded island, he naturally prefers to be by himself and has quite the wild temper. However, despite these traits he's a nice guy, and more than willing to abandon his post to help out his friends.

  • A Day in the Limelight: He got his own spinoff game, Knuckles Chaotix, for the Sega 32X.
  • The Ace: He's a guardian for life, a treasure hunter, a master of multiple types of martial arts, is able to break steel and mountains without any problem, is a cunning and intelligent Trap Master, knows every secret about chaos emeralds, and is ten times as powerful as Super Sonic.
  • Aloof Ally: Knuckles prefers to work in a solitude and keeping his distance from the others. But that's understandable since he is destined to live alone, guarding the Master Emerald.He doesn't mind working with others, but he prefers to work solely alone. It's even been lampshaded, in some of his theme songs, from the Dreamcast era:
    • "I was born by myself. I don't need a partner, i get it on by myself, adversaries get shelved" - Sonic Adventure
    • "This partnership is only temporary" - Sonic Adventure 2
  • Adorkable: Despite his tough exterior, he can be adorably awkward at times, especially around girls.
  • Almost Kiss: Shares one with Rouge after he saves her from falling in the lava in Sonic Adventure 2.
  • Anti-Hero: Has no hesitation in fighting other heroes or his own friends, if they get in his way.
  • Anti-Villain: In Sonic 3.
  • Art Evolution: Curiously, Knuckles got the least amount of changes to his design with the art revamp from Sonic Adventure and on, and it has remained consistent throughout the games and adaptations since, with one odd exception.
  • The Artifact: Knuckles was Sonic's original Foil and rival, and remained as such until Shadow's debut in Sonic Adventure 2. Afterward, he just became another one of Sonic's allies before losing all relevance to the series after Sonic Heroes. The only reason he even shows up nowadays is probably to remind people that he's still around.
    • This also extends to the Master Emerald as well. The Chaos Emeralds have supplanted it as the series` primary Macguffins, so the Master Emerald's only purpose was to give Knuckles an excuse to be in a game. Since Sonic Adventure 2, it's only been relevant in Sonic Advance 3 and Sonic Rivals; mostly it's only mentioned in passing nowadays.
  • Badass: One of the best examples in the series. His strength is said to be equal to Sonic's speed, and considering what his past feats detail: This probably isn't an exaggeration. He's also the most persistant fighter of the group, and consistently overpowers Super Sonic.
  • Badass Armfold: He does this very often, and it looks extremely badass, despite the fact that he's badass already.
  • Badass Baritone: Especially when voiced by Scott Dreier.
  • Badass Biker: In racing games, like Sonic Riders and Sonic & Sega All-Stars Racing, Knuckles usually rides a cycle of some kind.
  • Badass in Distress: The plot of Sonic Chronicles is kickstarted by Knuckles getting captured by the Nocturnus Clan. The gang spends a third of the game looking for him, but by the time they find him, he's managed to break himself out.
    • He also gets captured off-screen in Sonic Triple Trouble as Sonic (or Tails if you choose him) is seen freeing him from a cage during the ending.
  • Bare-Fisted Monk: Well, his name is Knuckles...
  • Belligerent Sexual Tension/Dating Catwoman: With Rouge in Sonic Adventure 2, complete with her nearly-Tsundere reactions towards him and an Almost Kiss when he saves her life (it doesn't help that "Kick The Rock!", the BGM for Wild Canyon — his first stage, right after he met Rouge — is a radar-jamming ballad of Intercourse with You, and later says that he doesn't love her). Later games have scaled back their romantic tension, reducing it to simple animosity.
  • Berserk Button: Knuckles will always get angry for a lot of things, but one thing in particular would be anything that would involve stealing the Master Emerald. He was also clearly enraged about how Wave insulted Tails's hover-board.
  • Beware the Nice Ones: Knuckles is level-headed, down to earth, and doesn't take crap from anyone. Doctor Eggman never learns from this. Knuckles is kind enough to give him multiple chances to redeem himself, but as soon as he finds out Eggman's been taken advantage of him, it's payback time.
  • The Big Guy: Tends to solve most of his problems by punching them.
  • Big "Shut Up!": He occasionally says this to certain characters in games such as Sonic Battle and Sonic Rivals.
  • Blood Knight: Knuckles is a brawler at heart, so he'd naturally be this. His counterpart, Gawain from Sonic And The Black Knight noted that fighting a dragon would be an excellent way to test out his strength.
  • Breakout Character: He was this during the 90s, especially since he had his own comic book, upgraded into the main cast with Sonic and Tails, and had his own video game.
  • The Brute: Served as Eggman's muscle in Sonic 3 & Knuckles and Sonic The Hedgehog Triple Trouble.
  • Butt Monkey: Many later incarnations are more bumbling in tone.
  • Cartoony Tail: Knuckles' tail looks like it had been broken at one point, but in-universe echidnas usually have tails like that.
  • Charles Atlas Superpower: Knuckles` strength is never explicitly stated to be abnormal or superhuman, but rather an innate part of his nature.
  • Character Development: A bit subtle, but he went from being an adversary to Sonic, to being reluctant allies with him, and finally good friends (albeit with a competitive streak.) It would take awhile before he would admit that Sonic is his friend, but after the OVA movie, it developed into a genuine friendship. He even became Sonic's second best friend next to Tails. Though he's still the first one to call Sonic out for acting like a Fearless Fool, they have developed a much more peaceful rivalry than with Sonic's other rivals.
  • Characterization Marches On / Flanderization: Knuckles' personality seems to depend on the era he's in; In the classic era, he was a chuckling troublemaker who hindered Sonic's path in his debut. In the Dreamcast Era, he was a tough, no nonsense foil to Sonic's carefree lifestyle. In the current, Modern Era he's even more of a hothead and finds himself constantly trying to one up Sonic, or play the series' Butt Monkey. In the Sonic Boom games, they dropped his trademark anger, and made Knuckles a complete moron who can't tell his left from his right, but then again, it's due to the Boom being a different universe.
  • The Comically Serious: Most evident in Sonic X.
  • Cool Shades: Gets a pair in Sonic Adventure 2 and in the Sonic Riders series.
  • Cute Little Fangs
  • Defeat Means Friendship/Defeat Means Respect: This is how he became an ally to Sonic. This also applies to his encounter with Rouge in Sonic Adventure 2.
  • Depending on the Writer: Probably one of the more notable cases, Knuckles` personality and relationships change more widely than others. The series can't seem to decide if he's a reluctant ally of Sonic's and prefers to be alone, or a Friendly Rival who wants to one-up Sonic and tries to tagalong in his adventures. Even how seriously he takes his guardian duties are subject to change; he either takes them completely serious and refuses to leave his post unless he's needed or constantly shirks his duties go hoverboarding, birthday parties, etc. etc. It's really hard to get a pin on him, the only consistent thing is his stoic and honorable nature, and his Friendly Rivalry with Sonic.
    • In Sonic 3 & Knuckles, he's a Giggling Villain constantly tripping up Sonic's progress by activating all of Angel Island's traps and secret mechanisms, suggesting he's crafty.
    • In Sonic Adventure and Sonic Adventure 2 he's a quiet loner with a strong sense of duty to the Master Emerald.
    • In the Sonic Riders series, he's a hot-headed competitor in the game, and a treasure hunter off-screen.
  • Determinator: Always persistent against pain, and never backs down.
  • Deuteragonist: He has a few prominent roles in Sonic Adventure and Sonic Chronicles in which these games lean to his connection with the Master Emerald and the Echidna clan.
  • Dishing Out Dirt: Some of his moves in Sonic Battle and Sonic Heroes.
  • Ditzy Genius: His trap master skills and smooth decisions prove him very intelligent, but his persistent trust in Doctor Eggman gives an illusion that he isn't bright on top of that.
  • Dreadlock Rasta: Word of God says his quills are styled in dreadlocks. Although he is not a Rastafarian, Knuckles is in some media known to be a somewhat spiritual character. From the Dreamcast games and beyond, we see that other echidnas have this, making it part of Knuckles' culture, and not a fashion choice.
  • Everyone Has Standards: It was pretty obvious from his reaction, that he wanted to punch Wave in the face for bullying Tails.
  • Fatal Flaws: Knuckles is known to be rather gullible and naive, falling for Eggman's trickery on a regular basis. His short temper can also lead to him being easily riled up at times. Also his pride has gotten him in quite a bit of trouble over time.
  • Fiery Red Head: Sometimes.
  • Fire-Forged Friends: With Sonic although both still have the tendency to quarrel.
  • Foil: As mentioned in his bio, he's one to Sonic. In fact, he was created with this trope in mind. He also gained one in Rouge after Sonic Adventure 2. They're both treasure hunters, but he's rather Hot-Blooded and simple minded, while she's cunning and manipulative.
  • Four-Temperament Ensemble: Melancholic
  • Friendless Background: He was actually born on Angel Island without anyone to look after him.
  • Genius Bruiser: Especially in Sonic 3, where he introduces himself by knocking Sonic out of his super form with one punch, and then afterwards set up traps for Sonic all around the place.
  • Giggling Villain: As an antagonist in Sonic 3 & Knuckles, where he constantly laughs at Sonic and Tails while messing with them.
  • Good Is Not Nice: Seems to be this in some games.
  • Good Is Not Soft: He's a selfless and caring hero who risks his life to save pretty much anyone and tries his best to give people a second chance, even the villain who abuses his trust, but if he has to use brutal force to stop a villain who just won't listen, he will.
  • Good Old Fisticuffs: He isn't called "Knuckles" for nothing.
  • Green-Eyed Monster: He's jealous of Sonic's adventurous lifestyle and fame he earns as a hero. This would explain his subtle hostility with the hedgehog, and their rocky relationship.
  • Grumpy Bear: Downplayed. Although not near to the level Shadow is, he often too serious to lighten up, although this stems from having to live alone in Angel Island for all his life. However, he's a rather mellow guy.
  • Guile Hero: Especially from Sonic 3 up to Sonic Adventure 2.
  • Gullible Lemmings: Tends to fall for Eggman's lies from time to time. Some fans exaggerate this to unrealistic levels.
  • Hair-Trigger Temper: Due to flanderization. He has a very short temper which can get the best of him at times. Characters like Sonic and Rouge are fond of pressing his buttons a lot.
  • Hero Antagonist: His debut had him opposing Sonic & Tails due to Eggman lying and claiming they were trying to steal the Master Emerald and Chaos Emeralds. So Knuckles is simply just protecting his home from what he believes are invaders. Once Eggman's lies are revealed, he quickly joins the duo in stopping him.
  • Heroic Neutral: Knuckles doesn't get himself involved in the conflict between Sonic and Dr. Eggman due to his dedication with guarding the Master Emerald, but he'll help Sonic and his friends when the situation calls for it.
  • Hidden Depths: He looks like a tough guy, but is a kind and helpful guy who just wants to do the right thing.
  • Hidden Heart of Gold: One line of his Sonic Adventure theme song "Unknown From M.E." states that he has "no such thing as weak spots."
  • Horrible Judge of Character: He trusts Eggman and thinks Sonic is the bad guy at first. He doesn't seem to learn from his mistake, as Eggman tricks Knuckles into fighting against Sonic again on several occasions. His lack of good character judgement becomes a Running Gag over time.
  • Hot-Blooded: As a result of Flanderization. He initially was, as mentioned above, a chuckling troublemaker in his debut and was rather mellow and down-to-earth (if not somewhat quick to anger, but not without justification) in the Adventure series and Heroes.
  • Humble Hero: Especially in the Sonic Adventure games, and Sonic Heroes. He is also the least arrogant rival of Sonic, while Shadow and Jet are more brash.
  • Idiot Ball: Knuckles is usually left holding this after he is tricked by others. This could get subverted though, as he holds a steadfast belief to believe in the good of people.
  • I Got Bigger: Has inexplicably doubled in height and seriously bulked up in Sonic Boom.
  • Image Song / "I Am" Song: "Unknown from M.E."
  • Ineffectual Loner: He fits into this category due to being stuck in Angel Island with the given responsibility to guard the Master Emerald all his life. He has gotten used to be alone, but he still admits that he would like to spend more time with people outside.
  • Inferiority Superiority Complex: Subverted. He is jealous of Sonic's freedom and getting the respect that he doesn't, but he's not trying to prove anything.
  • Informed Flaw: According to official profiles, he dislikes strong sunlight. This has never been mentioned in the games.
  • Informed Ability: A lot of manuals still mention his connection to the Master Emerald despite the fact that neither it, Angel Island, or even Knuckles himself are very relevant to the series nowadays.
  • Inspector Javert: His role in Sonic the Hedgehog 3.
  • Japanese Pronouns: "Ore" and "Oresama."
  • The Juggernaut: Super (and Hyper) Knuckles. Anything that Super Sonic can't handle, he can shake off.
  • The Lancer: Fits the traditional mold a lot better than Tails; literally everything about him is meant to be an opposite to Sonic and are generally presented as equals whenever Knuckles joins on adventures.
  • Last of His Kind: After the Chaos incident, he's the last surviving Echidna.
  • Let's You and Him Fight: How his altercations with Sonic in Sonic The Hedgehog 3, Sonic Adventure and Sonic Advance 2 went.
  • Lightning Bruiser: He's not quite as fast as Sonic, but Knuckles packs more of a punch.
  • Likes Older Women: Rouge teases him about this in Sonic Chronicles. She's two years older than him, and Shade is chronologically over 4000 years old.
  • Logical Weakness: Sonic Adventure 2 shows that he's uncomfortable dealing with ghosts, which makes sense considering that he's a Bare-Fisted Monk and would naturally have trouble dealing with them.
  • Loner-Turned-Friend: He starts becoming this after the events of Sonic Adventure 2. He often joins Sonic and Tails in their adventures in battling Eggman and other threats in the world.
  • Lovable Rogue: In Sonic 3, due to the fact that he was an Anti-Villain|ous pawn of Doctor Eggman, tricked due to his belief in the good of people, and tried his best to protect the Master Emerald.
  • Magma Man: Some of his moves in Sonic Battle and Sonic Heroes. Also his most commonly used element, seen in the Sonic Advance series and Sonic Heroes
  • Malicious Misnaming: He can be referred to as "Knucklehead" by Sonic on occasions in regards to him doing something thickheaded. Dr. Eggman has called him this in Sonic Adventure 2 while taking the Master Emerald.
  • Married to the Job: To the point where some fans turn it Up to Eleven and literally ship him with the Master Emerald.
  • Meaningful Name: Besides the more obvious spikes from his knuckles, ever since it was revealed that his ancestors were called the Knuckles Clan, it's become apparent that our Knuckles is actually named for his ancestors' tribe.
  • Mighty Glacier: Compared to the other characters. He's much slower than Sonic, but is also much stronger. Played straighter when competitively balanced.
  • Misunderstood Loner with a Heart of Gold: The thing is that Knuckles believes in always giving people a new chance, which is why he repetitively trusts the Easily Forgiven Eggman, who always abuses Knuckles's trust and takes advantage of him. Though it gets the group in trouble, Knuckles means well. Some people call him dumb for this, but he's simply easy with forgiving people due to believing in the good of people.
  • Mr. Vice Guy: As heroic as Knuckles can be at times, he does suffer about three vices. One, he can be prideful about his echidna heritage. Two, he's envious of Sonic's freedom and carefree nature. And three, he's quick to anger for a lot of things.
  • Nice Job Breaking It, Hero: This had gone hand in hand with his gullibility into thinking that Sonic was the bad guy. In his debut, this lead to Eggman to steal Master Emerald, and then in Sonic Adventure, he caused Sonic to fumble two Chaos Emeralds after the two collided with each other (Knuckles thought that the green Emerald was a shard of the Master Emerald), causing Eggman to take them and power up Chaos in his fourth form.
    Sonic: "Way to go, Knucklehead!"
  • Nobody Calls Me Chicken: You can get Knuckles to go along with a plan he initially disapproves of by either stroking or insulting his pride.
  • No Respect Guy: Most modern interpretations.
  • No Social Skills: Although he's become more laid-back and jovial, Knuckles has lived in isolation for most of his life, which may explain his gullibility and social naivety.
  • Not Quite Flight: His dreadlocks give him the ability to glide for long distances.
  • Not So Different: Although he and Sonic have contrasting lifestyles, the two share a sense of pride for certain things (Sonic with his speed while Knuckles with his guardianship and strength).
  • Not So Above It All: He's usually The Stoic, no-nonsense one of the trio, but sometimes he also drops in on the fun. His Friendly Rivalry with Sonic is also rather playful, despite being more mature than Sonic.
  • Out of Focus: Despite his appearance on this page, Knuckles has been out the spotlight for quite a few years. His last fully playable appearance(As in, not apart of a team or a temporary side character) was Sonic Adventure 2 a game over ten years old. And most of his appearances in the plot don't amount to much either.
    • Finally averted in Sonic Boom where he's once again a main character, yet acts completely different and is made out to be more of a comic relief.
  • Perpetual Frowner: Although some artworks of him show him smiling in games like Sonic 3 & Knuckles and Sonic Adventure, other artworks made him to be this later on the series, mostly to convey him as serious or hot-tempered.
  • Pintsized Powerhouse: He's one of the physically strongest characters in The Verse (if not the strongest), but only stands at a height of three feet, seven inches. In Heroes, he is notably the shortest of the "Power" characters by far.
  • Playing with Fire: His most commonly used element, seen in the series and Sonic Heroes.
  • Power Fist: Has these in Sonic Adventure and its sequel.
  • Pride: Has quite a bit of pride in his duty in guarding the Master Emerald and his Super Strength. Attacking his pride is one way to rile him up.
  • Proud Warrior Race Guy: Descendant from the "Knuckles Tribe", who were all just as boisterous and fight happy as he is.
  • Purple Eyes: They used to be black.
  • Real Men Wear Pink: His Super and Hyper forms in Sonic 3 & Knuckles.
  • Red Ones Go Faster: Inverted. Even though he has some degree of Super Speed, he pales in comparison to Sonic and most other characters.
  • Red Oni, Blue Oni: In addition to the aforementioned above, its also played straight with his other Friendly Rival Rouge.
  • Reformed, but Not Tamed: Downplayed. He started as a fairly antagonistic foe towards Sonic in his debut, but gradually developed into a quarrelsome yet trusted ally/friend.
  • The Rival: Initially served this role to Sonic, but it was more due to Eggman's manipulations, once the misunderstanding was clear, the two became friends although they still tend to have their disagreements on occasions.
    • He found a new one in Rouge, but its filled to the brim with Foe Yay due to her crush on him.
    • In the Sonic Riders series, he finds another rival in Storm when competing in Extreme Gear.
  • Rivals Team Up: With Sonic.
  • Running Gag: Being tricked by Eggman to fight Sonic. In the DS Sonic Colors, he gets tricked by Rouge in a subplot.
  • Save the Villain: He saved Rouge from falling back in Sonic Adventure 2, even if she was trying to steal the Master Emerald.
  • Screw Destiny: In "Sonic Shuffle", he inspirationally tells avoid that he won't lose what he protects to him, and that the only reason why dreams don't come true, is because people give up on them.
  • Screw This, I'm Outta Here!: He did this in Sonic Adventure 2. After the Master Emerald shards are lost during the approach to the ARK, Knuckles leaves Sonic and the others in the space shuttle to find them, with Tails stating that he bailed. After he successfully restores the emerald, he tries to reconnect with the others and finds Sonic, who asks him to look after Tails and Amy.
  • Seldom-Seen Species: Probably the first example of an echidna being a main character.
  • Ship Tease: Him and Rouge have their moments.
  • Shock and Awe: His "Thunder Arrow" Limit Break as a boss and a Battle Mode character in Sonic Adventure 2.
  • Shoryuken: Uses this in the Sonic Advance Trilogy as part of his Three Strike Combo and as an R-Trigger trick.
  • Shrinking Violet: Around girls.
  • Single Specimen Species: Initially.
  • Sixth Ranger: Started off as an antagonist before becoming an ally and rounding out the trio. Even after Sonic 3 he still only fights with the gang when the situation calls for it.
  • Slap-Slap-Kiss: His relationship with Rouge hits this territory at times.
  • The Stoic: He's not as openly emotional as Sonic or Tails, rather keeping everything to himself, even his background of being the last of his kind. He is also a determined ace.
  • The Spock: While he's faaaar from being an intellectual, he's the most serious and task orientated of the three.
  • Super Mode: In Sonic 3 & Knuckles, Super Knuckles and Hyper Knuckles. Though these forms are non-canon; the Super Emeralds are non-canon, and only Sonic, Shadow, and Silver currently have the ability to go Super.
    • Like Tails, Knuckles also has another Super Mode in Sonic Heroes. For the same reasons listed under Tails' section, there's quite a bit of confusion as to whether or not it's Super Knuckles or not.
  • Superpower Lottery: In most of the games he's been in, he has quite a but of control over the elements.
  • Super Strength: In spades.
  • Teeth-Clenched Teamwork: Initially with Sonic. The second verse of his theme "Unknown From M.E." shows his vehement view on teamwork.
    Don't approve of him, but you got to trust him
    This alliance has a purpose
    This partnership is only temporary
    • Also, when Sonic and Knuckles are selected as a team in Sonic Advance 3, both of their expressions are rather uncomfortable and disdainful. "Fighting Buddies" indeed.
    • Him and Rouge became this in Sonic Rivals 2. This is justified because Knuckles can't trust Rouge to help him retrieve the Master Emerald from Dr. Eggman.
  • There Is Another: In Adventure, Secret Rings, Black Knight, and Chronicles, he meets other echidnas even though he thought that he was the only echidna left.
  • Took a Level in Dumbass: In Sonic Boom.
  • Took a Level in Jerkass: In most games, Knuckles is hot-headed, and not very expressive, but maintains a friendly attitude, otherwise. However, in Sonic Battle and in the Sonic Rivals series, he's pretty nasty compared to his usual self.
  • Took a Level in Kindness: Back in "Sonic the Hedgehog 3", he acted as sort of a troll, who pulled lots of pranks on Sonic and Tails, until he found out, that he was being manipulated by Eggman. After joining them, Knuckles maintains a more friendly relationship with them, though he's still a bit short-tempered and usually prefers to be by himself.
  • Trademark Favorite Food: Fruits, especially grapes.
  • Tsundere: A rare male example, but he still has this quality in most incarnations.
  • Tsurime Eyes
  • Undying Loyalty: To his friends and the Master Emerald.
  • Unknown Rival: It seems to be something of a running gag in the current games where Knuckles will try to say something to one up Sonic, only to be ignored by him and put into some demeaning situation.
  • Unwitting Pawn: Occasionally this to Eggman.
  • Wall Crawl: Using the spikes on his knuckles as anchors, he can climb walls.
  • Well-Intentioned Extremist: In Sonic the Hedgehog 3.
  • Why Did It Have to Be Snakes?: His one fear, addressed almost exclusively in Sonic Adventure 2, is ghosts. The BGM for Pumpkin Hill, "A Ghost's Pumpkin Soup," has Knuckles proclaiming that he fears nothing, going as far as to proclaim that the ghosts are afraid of him, but he is seen to be visibly afraid when facing King Boom Boo (unused audio also had Knuckles exasperatedly shriek upon seeing the giant apparition). By Heroes, however, he seems to have overcome this, instead teasing Tails on his fear of ghosts in both Hang Castle and Mystic Mansion.
  • Wide-Eyed Idealist: According to his profile in Sonic Generations, the reason for his gullibility is his belief in the goodness of others.
  • Wise Beyond His Years: Is confirmed to be 16 years old, and has a few quotes of wisdom. One of them being this from Sonic Shuffle:
    Knuckles: "Dreams don't betray us. When we lose ourselves, that's when we lose our dreams. It's not that dreams don't come true. We just give up on them."
  • With Friends Like These...: With Sonic in the earlier games although later on, their teasing and arguing downsized.
  • The Worf Effect: He serves no purpose in Sonic Rush, other than showing how tough Blaze is, as she effortlessly defeats him.
  • Would Hit a Girl: He has absolutely no problem attacking Rouge to get the pieces of the Master Emerald back in Sonic Adventure 2, but he apologizes afterwards, and he had every right to punch her, since she's a jewel thief.
