{{Nihongo|'''Sonic the Hedgehog'''|ソニック・ザ・ヘッジホッグ|Sonikku za Hejjihoggu}} is the titular main protagonist of the [[Sonic the Hedgehog series|''Sonic the Hedgehog'' series]] and [[Sega]]'s mascot. He is an anthropomorphic hedgehog known for his ability to run faster than the speed of sound, hence his name. As his species implies, Sonic can also roll up into a concussive ball, primarily to attack enemies.

Born on [[Christmas Island]], Sonic abandoned his home at an early age to pursue a life of adventures. He has spent most of his life traveling around the world and beyond, usually accompanied by his best friend, [[Miles "Tails" Prower|Tails]]. In his journeys, he has defended his world and others from various threats, especially his arch-nemesis, [[Doctor Eggman|Dr. Eggman]].

During his many adventures, Sonic has traveled from the ends of the world to the far reaches of space and time, earning many titles, allies, and foes. Known for his attitude and somewhat short temper, yet strong sense of justice and love for freedom, Sonic's victories have made him a celebrated hero. However, he remains indifferent to his fame, preferring to live on his own terms.

==Concept and creation==
[[File:S1 needlemouse super.jpg|thumb|left|200px|Sketches of "Mr. Hedgehog", the character that would become Sonic the Hedgehog.|alt=Black-and-white sketches featuring a cartoon character that would become Sonic.]]
While several people have been involved in the creation of Sonic, the artist [[Naoto Ohshima]], programmer [[Yuji Naka]], and designer [[Hirokazu Yasuhara]] are generally credited with the creation of the character.

In April 1990, [[Sega]] sought a new mascot to rival [[Nintendo]]'s [[Mario]]; then-Sega president [[Hayao Nakayama]] in particular wanted a character as iconic as [[Wikipedia:Mickey Mouse|Mickey Mouse]].<ref name="alive">{{cite web |url=http://www.ign.com/articles/2007/01/27/sonic-the-hedgehog-vc-review |publisher=[[Wikipedia:IGN|IGN]] |last=Thomas |first=Lucas M. |date=January 20, 2007 |title=Sonic the Hedgehog VC Review |accessdate=February 23, 2014}}</ref><ref name="retro">{{cite journal |journal=[[Wikipedia:Retro Gamer|Retro Gamer]] |issue=100 |date=February 2012 |title=The Making of Sonic the Hedgehog |pages=46–49 |location=Bournemouth |publisher=[[Wikipedia:Imagine Publishing|Imagine Publishing]] |issn=1742-3155}}</ref><ref name="lame title">{{cite web |url=http://www.1up.com/features/essential-50-sonic |title=Sonic Boom |last=Kennedy |first=Sam |publisher=[[Wikipedia:1UP.com|1UP.com]] |archiveurl=https://web.archive.org/web/20110604011401/http://www.1up.com/features/essential-50-sonic |archivedate=June 4, 2011 |accessdate=September 24, 2014}}</ref> Sega had previously used [[Alex Kidd]] as their mascot, but because he was considered too similar to Mario, he was deemed unsatisfactory.<ref name="alive"/> The team at Sega's AM8 R&D department submitted several designs, including a wolf, bulldog, robot, and warrior character.

Sonic is an anthropomorphic hedgehog with blue fur that covers most of his body, and peach skin that covers his arms, muzzle, insides of his ears and front torso. He has small, triangular ears on top of his head, six long quills on the back of his head, two spines protruding from his back behind his shoulders, and a short tail. For attire, he wears [[Sonic's shoes|red shoes]] and white gloves.

Sonic's original design gives him a short body, with a round torso and black eyes. His current design features him in a taller and thinner body with green eyes. Originally, he was shown to have peach-skinned eyelids, until they were changed to blue in ''[[Sonic Heroes]]''.

They eventually befriended Knuckles and destroyed the space station for good, with Sonic transforming into [[Super Sonic]] with the seven Chaos Emeralds to chase Eggman into space.<ref>{{Cite game |dev1 = [[Sega Technical Institute]] |date = February 2, 1994 |game = Sonic the Hedgehog 3 |system = Sega Mega Drive |pub = [[Sega]]}}</ref><ref>{{Cite game |dev1 = [[Sega Technical Institute]] |date = October 18, 1994 |game = Sonic & Knuckles |system = Sega Mega Drive |pub = [[Sega]]}}</ref>

Sonic eventually found out that Eggman was seeking to tame [[Chaos]], an ancient god of destruction, to annihilate [[Station Square]]. He teamed up with Tails to acquire the Chaos Emeralds before Eggman did to power up the beast. Along the way, he met the ancient echidna spirit [[Tikal]], and from her learned much of the Chaos's violent history. Ultimately, despite Sonic's efforts, Chaos harnessed the seven Emeralds and transformed into [[Perfect Chaos]]. Sonic transformed into Super Sonic and defeated Perfect Chaos, reverting the creature to his original peaceful form.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = September 9, 1999 |game = Sonic Adventure |system = Dreamcast |pub = [[Sega]]}}</ref>

Sonic was later falsely framed as an escapee by the [[Guardian Units of Nations]] (G.U.N.) military. While fleeing persecution, he discovered that he had been mistaken with [[Shadow the Hedgehog]], who had teamed up with Eggman to adquire the seven Chaos Emeralds. Sonic partnered with his friends to uncover Eggman's plan, which was to hold the world hostage with the [[Eclipse Cannon]], a superweapon held onboard the [[Space Colony ARK]]. The heroes infiltrated the colony to sabotage the doctor's scheme. Although they ultimately failed, both parties learned that they had been fooled by an elaborate revenge plan posthumously initiated by Eggman's late grandfather, [[Gerald Robotnik]].

Sonic was later defeated by [[Infinite]], Eggman's new right-hand man who was using a mysterious gem known as the [[Phantom Ruby]] to empower himself. He was then held captive onboard the rebuilt Death Egg. Without his nemesis to foil him, Eggman conquered the world but was opposed by Sonic's friends, who formed a guerrilla group known as the [[Resistance]], triggering the [[War to Take Back the Planet]]. After six months of captivity, Sonic was freed by a Resistance recruit known as the "[[Avatar]]" and reunited with Classic Sonic. The trio, alongside the rest of the Resistance, faced off against Eggman's army and Infinite, ultimately overthrowing the doctor's regime.<ref>{{Cite game |dev1 = [[Sonic Team]] |date = November 7, 2017 |game = Sonic Forces |system = Nintendo Switch |pub = [[Sega]]}}</ref>

As such, despite his loyalty to his friends and allies, Sonic is typically reluctant to commit to anything that requires him to act primarily under the authority of others, including his friends.

Sonic is an optimistic individual; as mentioned by his friends, he always puts a positive spin on things.<ref name="StH12">[[IDW Sonic the Hedgehog Issue 12|''Sonic the Hedgehog'' #12]], "The Cost of the Battle for Angel Island"</ref> He thus refuses to give into despair, even when faced with a hopeless situation, although he has been known to drop his positivity in the darkest moments in favor of a more sympathetic outlook and somber mood.<ref name="StH23">[[IDW Sonic the Hedgehog Issue 23|''Sonic the Hedgehog'' #23]], "The Last Minute, Part 3"</ref><ref name="StH24"/> Despite this, he never gives up and always fights to the end, believing firmly in the righteousness of his decisions and refuses to compromise his ideals and morals out of fear.<ref name="StH23"/><ref name="StH44">[[IDW Sonic the Hedgehog Issue 44|''Sonic the Hedgehog'' #44]], "Zeti Hunt, Part 4"</ref> Also, since he is a hedgehog of action and is constantly looking for new adventures and challenges for himself, having nothing to on an adventure will severely bore Sonic, and staying cooped up for too long tends to make him uneasy due to his hatred of confinement.<ref name="StH34">[[IDW Sonic the Hedgehog Issue 34|''Sonic the Hedgehog'' #34]], "Chao Races and Badnik Bases, Part 2"</ref>

[[File:IDW_advert_Sonic.png|thumb|Sonic the Hedgehog, from [[IDW Sonic the Hedgehog Issue 1|''Sonic the Hedgehog'' #1]].]]
Sonic's personality is a juxtaposition of kindness and ferocity. Extremely benevolent, Sonic's heroism is an extension of his philosophy;<ref name0"FCB2021">''[[IDW Sonic the Hedgehog Free Comic Book Day 2021|Sonic the Hedgehog Free Comic Book Day 2021]]'', "Race to the Empire"</ref> preferring to keep things simple, Sonic lives for the moment and wants to see the world and enjoy all the thrills and adventures that come from that.<ref name="StH50"/> Sonic lives his life according to this sense of freedom and wants everyone else to have the freedom to do that too. As such, if he were to take a life, he would be taking away that person's freedom too, which goes against his own rules. Similarly, the peace he has made with several of his enemies in the past has taught him that there are better alternatives to neutralizing a threat than eliminating it, having experienced difficult cases of villains who wanted to destroy the world but were reformed by him and his allies.<ref name="StH50"/> As such, while he does everything he can to snuff out evil, he is always willing to give people that he has "a rocky start" with a chance to rebound and reform themselves so they can restart their relationships on better terms, a philosophy that he is willing to extend even to villains like Dr. Eggman or [[Doctor Starline|Dr. Starline]].<ref name="StH50"/> He similarly cannot turn away when someone is in need of aid. Most noticeably, after helping defeat {{IDWlink|Metal Sonic}}, he compassionately had the robot repaired in hopes he could convince him to abandon his evil ways.<ref name="StH12" /> He likewise believes that even the worst person has good in them.<ref name="StH23"/> Far from a pacifist, however, Sonic refuses to let anyone take away the freedom of others, even when they follow his own philosophy, and will willingly resort to physical methods when a peaceful route is not feasible.<ref name="StH50"/> As such, he recognizes that peaceful methods do not always work, especially when dealing with an unpredictable enemy. 

If Sonic has a flaw besides recklessness and a certain disregard for authority, it is that he tends to take things too much upon himself.<ref name="StH16">[[IDW Sonic the Hedgehog Issue 16|''Sonic the Hedgehog'' #16]], "Infection"</ref><ref name="StH31">[[IDW Sonic the Hedgehog Issue 31|''Sonic the Hedgehog'' #31]], "Recovery, Part 1"</ref> Another flaw of his is that he puts a lot of faith in the belief that everyone, even villains like Eggman, has some good in them and are redeemable, something that he himself sometimes regrets and individuals like {{IDWlink|Shadow the Hedgehog|Shadow}} and {{IDWlink|Espio the Chameleon|Espio}} challenge.<ref name="StH23"/><ref name="StH6">[[IDW Sonic the Hedgehog Issue 6|''Sonic the Hedgehog'' #6]], "The Fate of Dr. Eggman, Part 2"</ref><ref name="StH24"/> Also, because he knows that giving others a choice cannot prevent them from making poor decisions, Sonic tends to become disappointed when those he gives a second chance to choose an undesirable path.<ref name="StH50"/> This does not make him naïve, because he is still aware when enemies pose too much of a threat to be reasoned with.<ref name="StH25"/>

Sonic cares deeply for his many friends. Despite his loyalty to them, though, he never lingers too long in one place. However, his friends know he will be cruising back into their lives in no time.<ref name="SonicTradingCard"/>

As the amnesiac Mr. Needlemouse, Sonic was a more aloof and relaxed individual, taking great interest in learning new things he had not heard of before.<ref name="StH31" />

==Powers and abilities==
Despite not having undergone any known training, Sonic's years of battles have made him a skilled and powerful fighter. He has defeated [[Death Egg Robot|giant]] [[Egg Dragoon|robots]], [[Zeti|demons]], and [[Perfect Chaos|god-like beings]] on his own; gone up against and bested [[Master Zik|those]] with far more combat experience; and even beaten [[Shadow the Hedgehog|individuals]] who equally match his abilities. It has also been noted that Sonic is steadily growing stronger;<ref>[[Sonic Team]], [[Dimps]] (November 12, 2010). ''[[Sonic Colors (Nintendo DS)|Sonic Colors]]''. [[Nintendo DS]]. [[Sega]]. Area/Level: [[Sweet Mountain]]. "'''Sonic''': Heh!

[[Sega]]. Area/Level: [[Emerald Beach]] ([[Rouge the Bat|Rouge]]'s story). "'''[[Rouge the Bat|Rouge]]''': You've got much stronger... / '''Sonic''': I've got something to protect..."</ref> His victories over [[Emerl]] at the Gizoid's maximum potential and Perfect Chaos in his base form are prime examples of his true power.

Sonic's greatest strength is his super speed.<ref name="JamProfile" /> He has proven himself to be in a class of his own with his speed, having been credited as "the fastest thing alive" and even the fastest being in the universe.<ref name="SRProfiles">''[[Sonic Rivals]]'' ([[PlayStation Portable]]) United States instruction booklet, pg. 8.</ref> He has the ability to instantly accelerate to the speed of sound and run at speeds that exceed [[wikipedia:Mach number|Mach 1]],<ref name="JamGuide" /><ref name="JamProfile" /><ref name="Interview 2">{{Cite web |author=[[Sega/Sega of America|Sega of America]] |publisher=[[Sega]] |url=http://www.sega.com:80/sonic/community/post_sonicqa.php?article=sonicqa |archiveurl=https://web.archive.org/web/20040613171218/http://www.sega.com:80/sonic/community/post_sonicqa.php?article=sonicqa |archivedate=June 13, 2004 |title=Sonic Q and A |quote='''From Your Ultimate Fan''': How fast can you go (MPH) and how long would it take you to run around the world once?

''[[Sonic and the Black Knight]]''. [[Wii]]. [[Sega]]. Cutscene: Opening.</ref> This speed also allowed him to restore the time and space erased by the [[Time Eater]] during that [[Sonic Generations|incident]]. Even then, Sonic can take his speed even further. By [[Super Peel Out|revving up in one place]], he can take off at turbo speeds in an instant. He can also [[Boost|envelope himself in a blue energy field]] that lets him accelerate beyond the sound barrier on both the ground and in midair for a short time,<ref>''[[Sonic Unleashed]]'' ([[PlayStation 3]]) European instruction booklet, pg. 12.</ref> allowing him to not only smash straight through enemies and obstacles like a living projectile, but also [[Air Boost|fly]] immense distances through midair. Using [[Light Speed Dash|certain]] [[Light Speed Attack|techniques]], he can even momentarily reach the speed of light.

It is unknown what Sonic's unaided top speed is. During the Emerl [[Sonic Battle|incident]], it was stated he can move several times the speed of sound and when facing Emerl at his maximum potential, he went at least ten rounds with him in less than thirty seconds. He is also able to run in circles around an enemy at such speeds that he can stun it.<ref name="CDCredits">[[Sonic Team]] (November 19, 1993). ''[[Sonic the Hedgehog CD]]''. [[Sega CD]]. [[Sega]].

[[File:Sonic dodging Egg Fighter.jpg|thumb|225px|Sonic easily avoiding an [[Egg Fighter]] at high speed, from ''[[Sonic Unleashed]]''.]]
Sonic has demonstrated complete mastery of his speed in any environment and can use it for both high-speed offense and defense.<ref>''[[Sonic Rivals 2]]'' ([[PlayStation Portable]]) United States instruction booklet, pg. 7.</ref> Not only can he run at maximum tilt in straight lines, but also in full tight circles and through sharp turns with full control over his momentum. As far as stamina goes, Sonic's is seemingly limitless as he is never winded from running. His speed also allows him to perform several impressive feats; he can [[Sonic Heal|heal at rapid speeds]], launch [[Sonic Wave|shockwaves]] by spinning rapidly, [[Sonic Ballet|leap]] in midair, launch [[Somersault|stunning waves]] with fast kicks, increase the force of his blows by striking with increased momentum, and create [[Insta-Shield|barriers of super speed]]. He can also [[Blue Tornado|spin in circles]] or [[Tornado (Custom Action)|rotate his extremities]] at super speed to create winds strong enough to attack or blow away opponents, similar to aerokinesis.

Sonic possesses astounding kineticism and precision, and has the reaction time to match his speed. He has profound [[Parkour|acrobatic skills and agility]], along with incredible reflexes that lets him avoid any incoming obstacles with precise and delicate movements. As seen in his first meeting with [[Silver the Hedgehog|Silver]], Sonic can even detect attacks beyond his field of vision due to his sharp reflexes.<ref name="SonicAndSilverMeet">[[Sonic Team]], [[Blindlight]] (November 14, 2006). ''[[Sonic the Hedgehog (2006)|Sonic the Hedgehog]]''. [[Xbox 360]]. [[Sega]]. Cutscene: Silver appears (Sonic Episode).</ref> When launched into the air, he can also pull off several [[Trick Action|tricks]] before landing. He also has incredible jumping skills,<ref name="RUSManual" /> capable of jumping up to several hundred meters, even with extra weight.<ref>[[Sonic Team]], [[Blindlight]] (November 14, 2006). ''[[Sonic the Hedgehog (2006)|Sonic the Hedgehog]]''. [[Xbox 360]]. [[Sega]]. Cutscene: The Chaos Emeralds entrusted (Sonic Episode).</ref>

Sonic possesses notable strength. He can push and lift things bigger and heavier than himself, run without extra weight slowing him down, smash through metal and rock, and damage [[Dark Gaia|foes]] countless times his size. However, it is debatable whether the latter's power comes from his speed, strength, or a combination of both. Sonic's strength particularly lies in his legs; with a single kick, he can topple the [[Egg Golem (Sonic Adventure 2)|Egg Golem]]<ref>[[Sega Studio USA|Sonic Team USA]] (June 23, 2001). ''[[Sonic Adventure 2]]''. [[Dreamcast]]. [[Sega]]. Area/Level: [[Egg Golem (Sonic Adventure 2)|Egg Golem]] (Dark story).</ref> and send [[Badnik]]s [[Flying Kick|flying]]. This does not mean that Sonic's arms are not strong either; he has enough strength to tear robots apart by hand<ref name="CDCredits" /> and punch through a collapsed wall.<ref>[[Sonic Team]] (March 13, 2009). ''[[Sonic and the Black Knight]]''. [[Wii]]. [[Sega]]. Cutscene: World Destruction.</ref>

Sonic has frequently demonstrated extreme resilience to damage. He can survive getting caught in the crossfire from all angles by Eggman's robots (which only knocked him out cold briefly), withstand the force of a massive explosion and a [[Hyper-go-on]]-based void unscathed, being pummeled with swords, resist a powerful punch from [[Knuckles the Echidna|Knuckles]] from his foot, smash through several robots with his fist without discomfort, and take a ruthless pummeling from the [[Time Eater]].<ref name="FinalBattle">[[Sonic Team]] (November 4, 2011). ''[[Sonic Generations]]''. [[PlayStation 3]]. [[Sega]]. Cutscene: [[Sonic Generations/Script#The Final Battle|The Final Battle!]].</ref> Additionally, Sonic has [[Sonic the Hedgehog 2|more]] [[Sonic the Hedgehog 3|than]] [[Sonic Adventure|once]] survived impacts from falls at extreme heights, bordering at the edge of space, only to shake it off when landing, and has even withstood [[Wikipedia:Atmospheric entry|atmospheric entry]].

{{Quote left|Even at night, when I'm like this, I'm still myself. Not like all the other people we've seen.

Sonic possesses an unbreakable and incorruptible spirit; in situations where most others would give up and where he is severely outnumbered and outgunned, Sonic never loses faith in himself and never surrenders. This trait enables him to keep on fighting when utterly exhausted or after taking an abnormal amount of damage.<ref>[[Sonic Team]] (March 13, 2009). ''[[Sonic and the Black Knight]]''. [[Wii]]. [[Sega]]. Cutscene: Queen of the Underworld.</ref> His will even lets him withstand mind-controlling powers, like the corruptive influence of [[Dark Gaia]]. Even when possessed by the [[Ifrit]], Sonic was arguably able to occasionally regain control.

Sonic has also demonstrated the ability to harness [[Chaos Emerald energy]] for his own use; with a [[Chaos Emerald]], Sonic can perform the [[chaos powers|chaos power]] [[Chaos Control]], and occasionally gain a boost in power.

[[File:Sonic 23.png|thumb|225px|Sonic performing the [[Spin Attack]], from ''[[Sonic Labyrinth]]''.]]
Sonic's core offensive maneuver is the [[Spin Attack]], a technique where he curls into a concussive ball or cutting disk and directs himself at his targets. With it, Sonic can shred or burrow through just about any substance given enough speed and hit with enough force to pierce colossal boulders.<ref>[[Sonic Team]] (November 19, 1993). ''[[Sonic the Hedgehog CD]]''. [[Sega CD]]. [[Sega]]. Area/Level: Opening sequence.</ref> Highly adept in its usage, Sonic can utilize several variants of the Spin Attack for both grounded and aerial maneuvers, including the [[Spin Dash]], [[Spin Jump]], [[Homing Attack]], the super-charged [[Focused Homing Attack]], and the [[Light Speed Attack]], which attacks at the speed of light.

Even without his Spin Attack, Sonic is a skilled hand-to-hand combatant. He mostly relies on his fast footwork since the majority of his power lies in his legs, though he has been known to use his fists and arms from time to time, albeit in a rather straightforward manner. His fighting style is mostly derived from [[Wikipedia:Breakdance|breakdancing]] moves<ref>''[[Sonic Battle]]'' ([[Game Boy Advance]]) United States instruction booklet, pg. 3.</ref><ref>[[Sonic Team]] (February 27, 2004). ''[[Sonic Battle]]''. [[Game Boy Advance]]. [[Sega]]. "'''[[Sonic Flare]]''': Sonic's heavy attack. He performs a Downward Kick using breakdance moves, which knocks opponents away."</ref> which utilize Sonic's legs to their fullest, allowing him to deliver swift, wide-ranged kicks. He has also been known to use flying forward kicks, split kicks, and scissor kicks.<ref>[[Super Smash Bros. for Nintendo 3DS and Wii U|''Super Smash Bros. for Nintendo 3DS'' and ''Wii U'']]</ref> Sonic was also shown during the [[scabbard of Excalibur]] [[Sonic and the Black Knight|incident]] to excel in swordsmanship. Even as a rookie swordsman, Sonic could beat a [[Mist Dragon|dragon]] and after receiving formal training, he could best master swordsmen like the [[Knights of the Round Table]]. In addition to using advanced techniques, Sonic can apply his speed to his swordplay for quick and swift slashes, and become a buzzsaw by spinning with his sword, enabling him to slice clean through enemies. He has also learned the martial art of Linshao Kung Fu from [[Shuifon]], though he is yet to be seen using it.

[[File:Sonic pose 62.png|thumb|left|225px|Sonic delivering a powerful kick, from ''[[Sonic Battle]]''.]]
Sonic has extraordinary skill in operating vehicles. He has excellent skills when it comes to piloting planes like the [[Tornado]], and water bike surfing on vessels like the [[Wave Cyclone]]. He is also experienced in a variation of sports such as boarding and surfing, and other recreational activities like [[grinding]]. As shown during [[Dodon Pa]]'s [[Team Sonic Racing|Grand Prix]], Sonic is also an expert at driving sport cars like the [[Speed Star]]. He has even demonstrated that he is capable of driving his car sideways and backwards just as well as he can forwards, and can keep up with other expert drivers like Shadow while driving from these directions.<ref>{{Cite episode |title=[[Dangerous Distractions]] |series=[[Team Sonic Racing Overdrive]] |season=1 |number=1 |network=[[Wikipedia:YouTube|YouTube]] |date=March 16, 2019}}</ref>

Sonic has proven himself as a world-class [[Extreme Gear]] rider. He is said to move faster than he can run on an Extreme Gear<ref name="SRZGprofile">''[[Sonic Riders: Zero Gravity]]'' ([[Wii]]) United Kingdom instruction booklet, pg. 4.</ref> and can go head-to-head with legendary Wind Masters like [[Jet the Hawk]]. Sonic seemingly has a knack for Extreme Gear riding, quickly grasping the controls on his first try and later developing advanced techniques despite being self-taught. After the [[Sonic Free Riders|second]] [[World Grand Prix]], Sonic can be considered the best Extreme Gear rider in the world, having beaten [[Metal Sonic]] in a race, who at that point was an "unbeatable" rider with the skills of the world's finest Extreme Gear riders at his disposal.

It appears that Sonic can control the strength and durability of his otherwise soft quills at will.<ref>Sonic's Up Throw, ''[[Super Smash Bros. Brawl]]''</ref> While he is spinning, they appear to be extremely hard like buzzsaw blades; as demonstrated during the [[Neo Metal Sonic]] [[Sonic Heroes|incident]], his quills (and body) are durable enough to slice through battleships without even moving at the speed of sound. In addition, Sonic's quills can sense nearby dangers, which they warn him about by creating a tingling sensation.<ref name="TinglingQuills"/> A similar precognitive ability of his that allows him to sense nearby danger comes in the form of sneezing.<ref name="JamGuide" /> Sonic has also demonstrated the ability to transfer his speed throughout various parts of his body, allowing him to immediately set off from stationary positions and even channel it into objects to speed up their movements and make them pierce through solid objects as he does while running. He can also create an [[Time Stop|effect reminiscent of a time halt]], even though it is unknown what it is derived from.

During the [[World Ring]] [[Sonic and the Secret Rings|incident]], he also wore [[Shahra's Ring]], allowing him to harness [[Shahra]]'s magic for himself. Similarly, during the [[scabbard of Excalibur]] [[Sonic and the Black Knight|incident]], Sonic would wield swords; he initially wielded [[Clarent]], but later exchanged it for Caliburn, a sapient [[sacred sword]] with magical properties.

[[File:IDW42Sonic.jpg|thumb|left|235px|Sonic breaking the sound barrier as he runs to [[Restoration HQ]], from [[IDW Sonic the Hedgehog Issue 42|''Sonic the Hedgehog'' #42]].]]
Sonic's trademark ability is his super speed. He can travel up to speeds surpassing Mach 1, which is at the blistering speed of about 768&nbsp;mph(1234 km/h). He also utilizes this in hand-to-hand combat as shown when facing {{IDWlink|Neo Metal Sonic}}, giving him quick reflexes and reaction time. While running, Sonic resembles a blue streak from a distance that leaves a blue trail behind him.<ref name="StH7">[[IDW Sonic the Hedgehog Issue 7|''Sonic the Hedgehog'' #7]], "Meet the New Boss"</ref><ref name="StH42"/> At the same time, he is experienced enough with his speed to turn easily while maintaining his speed.<ref name="StH1"/>

While Sonic's top speed is unknown, glimpses of Sonic's prowess are shown in his tendency to routinely scale vertical walls,<ref name="StH3">[[IDW Sonic the Hedgehog Issue 3|''Sonic the Hedgehog'' #3]], "Fallout, Part 3"</ref> effortlessly knock down enemies in his path,<ref name="StH1"/> run over water,<ref name="StH2"/> and ability to build up enough momentum to throw [[Egg Spear|spears]] with such force that they can pierce large metal structures while exerting enough air pressure to blow said structures apart.<ref name="StH7"/> His speed also allows him to perform several impressive feats, such as creating small tornadoes by running around in circles at super speeds.<ref name="StH19">[[IDW Sonic the Hedgehog Issue 19|''Sonic the Hedgehog'' #19]], "Crisis City, Part 1"</ref><ref name="StH51">[[IDW Sonic the Hedgehog Issue 51|''Sonic the Hedgehog'' #51]], "Escaping the Empire"</ref> Sonic's speed is so great that he could eventually outpace a spatial maze reality that folds back in on itself ad infinitum, which even Dr. Eggman knew could not hold Sonic for long.<ref name="StH37">[[IDW Sonic the Hedgehog Issue 37|''Sonic the Hedgehog'' #37]], "Test Run, Part 1"</ref><ref name="StH40">[[IDW Sonic the Hedgehog Issue 40|''Sonic the Hedgehog'' #40]], "Test Run, Part 4"</ref> Sonic can also use the [[Boost]] to not only increase his speed but also barge through obstacles in his path.<ref name="StH2"/> 

Sonic has demonstrated complete mastery of his speed at nearly any level. Not only can he run at a maximum tilt in straight lines, but also through sharp turns with full control over his momentum, and without recklessly crashing into unintended targets. To match his super speed, Sonic also has immense, though not quite limitless,<ref name="StH19"/><ref name="StH23"/> stamina that allows him to run at high speed for days without rest.

Sonic is also a skilled acrobat with quick reflexes and reaction time to match. He is able to perform a variety of aerobatic moves and techniques, even while running.<ref name="StH1"/> Despite his size, he also has great physical strength; he is able to easily fling Amy Rose and her [[Piko Piko Hammer]] several feet into the air singlehandedly,<ref name="StH2"/> overpower Master Overlord's giant grip alongside {{IDWlink|Shadow the Hedgehog|Shadow}} and {{IDWlink|Knuckles the Echidna|Knuckles}},<ref name="StH11">[[IDW Sonic the Hedgehog Issue 11|''Sonic the Hedgehog'' #11]], "The Battle for Angel Island, Part 3"</ref> and set off with enough power to bend thick metal armor.<ref name="StH2"/> Sonic can also ascend hundreds of meters into the air with a single jump.<ref name="StH2"/> He is also incredibly durable, being capable of taking a hit from an artillery shell and emerging from it without a scratch,<ref name="StH7"/> as well as enduring several powerful blows from {{IDWlink|Zavok}} without any serious injuries.<ref name="StH43">[[IDW Sonic the Hedgehog Issue 43|''Sonic the Hedgehog'' #43]], "Zeti Hunt, Part 3"</ref>

Sonic possesses the ability to harness the power of the {{IDWlink|Chaos Emerald}}s. With them, Sonic can give himself a boost in power.<ref name="StH8">[[IDW Sonic the Hedgehog Issue 8|''Sonic the Hedgehog'' #8]], "Silent Support"</ref> He is also a capable aerial pilot, able to properly pilot the {{IDWlink|Tornado}} at high speed, although he is not nearly as skilled as Tails.<ref name="StHAnnual2019s2">''[[Sonic the Hedgehog Annual 2019]]'', "Jet Set Tornado"</ref>

Sonic's core offensive maneuver is the [[Spin Attack]], a technique where he curls into a concussive ball or cutting disk and directs himself at his targets. With it, Sonic can shred or burrow through just about any substance given enough speed, and perform moves like the [[Spin Dash]], [[Homing Attack]] and [[Rolling Combo]], though the last one requires the aid of {{IDWlink|Miles "Tails" Prower|Tails}}.<ref name="StH1"/><ref name="StH2"/>

[[File:SFSBSuperSonic.png|thumb|left|225px|Sonic transformed into Super Sonic, from ''[[Sonic Forces: Speed Battle]]''.]]
By harnessing the power of the seven [[Chaos Emerald]]s, Sonic can enter a [[Super transformation|Super State]], transforming him into '''Super Sonic'''. Easily his most used transformation, Super Sonic is one of Sonic's strongest forms. In this state, all of Sonic's abilities far surpass his normal ones. He is also able to fly and is nearly invulnerable.<ref name="Super Sonic Channel">{{Cite web|author=[[Sonic Team]]|publisher=[[SEGA]]|url=http://sonic.sega.jp/chara/supersonic/index.html|archiveurl=http://web.archive.org/web/20080701142150/http://sonic.sega.jp/chara/supersonic/index.html|archivedate=July 1, 2008|title=Sonic Channel|work=Characters: Super Sonic|accessdate=June 25, 2008|language=Japanese}}</ref> However, this transformation consumes a lot of energy, meaning it cannot be maintained for long.

=====Super Sonic 2=====

[[File:Starfall supersonic-profile.jpg|thumb|right|200px|Super Sonic transformed into Super Sonic 2, from ''[[Sonic Frontiers]]''.]]
By harnessing the power of the [[Cyber corruption]] at half its potential, Super Sonic can enter a superior state, transforming him into '''Super Sonic 2'''. Being a "successor" of Super Sonic, this form retains the same traits as it, except Super Sonic 2 gains a power and speed increase.

====Color Powers====
{{Main|Color Power}}
[[File:Lazer-Wisp.png|thumb|left|225px|Sonic as the [[Cyan Laser]], from the [[Wii]] version of ''[[Sonic Colors]]''.]]
By harnessing different variants of [[Hyper-go-on]] from [[Wisp]]s, Sonic can use specific '''Color Powers''' to transform into a certain form, such as a drill, a laser or even a fireball, each one possessing its own unique abilities. So far, Sonic has been able to transform into the [[Cyan Laser]], [[Yellow Drill]], [[Blue Cube]], [[Green Hover]], [[Pink Spikes]], [[Purple Frenzy]], [[Violet Void]], [[Orange Rocket]], [[Red Burst]], [[Indigo Asteroid]], [[Magenta Rhythm]], [[Crimson Eagle]], [[Ivory Lightning]], [[Gray Quake]], [[Black Bomb]], and [[Jade Ghost]]. However, these transformations require a steady supply of Hyper-go-on to be maintained.

==Weaknesses==

This matches all my other data perfectly!"</ref> Furthermore, whilst underwater, Sonic's speed will be greatly decreased.<ref name="LabyrinthZone8-bit" />

It has been stated that if Sonic does not sleep for eight hours during the night, it will spoil his running.<ref>{{cite web |author=[[Sega/Sega of America|Sega of America]] |publisher=[[Sega/Sega of America|Sega of America]] |url=http://www.sega.com/sonic/globalsonic/post_sonicteam.php?article=nakainterview |archiveurl=http://web.archive.org/web/20040124111152/http://www.sega.com/sonic/globalsonic/post_sonicteam.php?article=nakainterview |title=Sonic Central |archivedate=January 24, 2004 |date=February 2004 |quote='''Sega.com''': Sonic sure is busy -- how many hours of sleep does he need per night? / ''[[Yuji Naka]]''': Hmm, I suppose he sleeps the ordinary eight hours a night or so, because unless he sleeps well, lack of sleep will affect his run...}}</ref> In addition, he has trouble keeping his balance when coming to a sudden halt when running at high speed.

Because of Sonic's giant internal ego, he often banters and plays around with his enemies. This usually makes him underestimate his opponents and leave his guard down, as seen during his encounter with [[Infinite]] in [[Mystic Jungle]] during the [[War to Take Back the Planet]] and when he got trapped by Eggman onboard the [[Chaos Energy Cannon]] at the start of the [[Dark Gaia]] [[Sonic Unleashed|incident]]. Also, his impulsiveness and recklessness can often cause trouble, such as during the [[Lost Hex]] [[Sonic Lost World|incident]] where he got rid of Eggman's [[Cacophonic Conch]], which Eggman used to keep the [[Deadly Six]] in line, before listening to Tails' warnings about the conch.

===IDW Publishing===
Although well-versed in his own super speed, Sonic has trouble building up his speed in unfavorable environments, like in deep snows where it is hard to get traction or inside small rooms.<ref name="StH14">[[IDW Sonic the Hedgehog Issue 14|''Sonic the Hedgehog'' #14]], "Misdirection"</ref><ref name="StH34"/> Additionally, Sonic's stamina is not unlimited; if pushed to run often for several days on end with little to no sleep, Sonic's stamina can reach its limits, causing him to feel actual fatigue and exhaustion.<ref name="StH19"/><ref name="StH23"/>

After Sonic does a mistake that causes his reality to shatter, he must go on an adventure of redemption and self-discovery to save the friends he once took for granted. He quickly learns that these new worlds and its inhabitants are not as friendly as his usual friends, but that doesn't stop the energetic and charismatic hedgehog to try and befriend them. Sonic also needs to befriend his old rival Shadow once again, which proves to be a difficult task.

In the ''[[Sonic the Hedgehog (film series)|Sonic the Hedgehog]]'' film series produced by [[Paramount Pictures]] and its spin-offs, Sonic is an anthropomorphic blue hedgehog from [[Mobius (Paramount)|Mobius]] who was born with immense powers that are desired by many people. He lived with his parental figure, [[Longclaw]], until he was forced to leave his home planet to go to planet [[Earth (Paramount)|Earth]]. He lived hidden from the society for ten years, until he was forced to leave his home again, since he was wanted by [[Doctor Robotnik (Paramount)|Dr. Robotnik]]. Trying to escape, Sonic hid in [[Tom Wachowski]]'s garage, but is discovered and shot by a soothing dart from the police officer, causing him to lose his [[Ring (Paramount)|Rings]], his only way to escape. Both had to recover the Rings and escape from the evil Robotnik, who wished to obtain Sonic's powers to conquer the world, but Sonic heroically defeats Robotnik and banishes him into the [[Mushroom Planet]] and resettled in Green Hills with the Wachowski family. Later, Sonic found himself in a race to recover the [[Master Emerald (Paramount)|Master Emerald]] with his newfound partner [[Miles "Tails" Prower (Paramount)|Tails]] before it fell into the hands of Robotnik and [[Knuckles the Echidna (Paramount)|Knuckles the Echidna]]. Later teaming up with Knuckles as well, Sonic managed to defeat Robotnik and began to swore to protect the Master Emerald with Tails and Knuckles while they resided with him and the Wachowskis.

In the ''[[Sonic the Hedgehog (IDW comic series)|Sonic the Hedgehog]]'' comic series and its spin-offs published by [[IDW Publishing]], Sonic's past is virtually identical to his video game counterpart's, up until after the events of ''[[Sonic Forces]]''. After the [[Eggman War]], Sonic traveled the world to destroy the remaining [[Badniks]], who had been left directionless following [[Doctor Eggman|Dr. Eggman]]'s disappearance. It later turns out that Eggman had lost his memory, and that [[Neo Metal Sonic]] had taken control of [[Eggman Empire]]. Together with his friends, Sonic defeated Metal Sonic, but let him go, convinced that without Eggman, he would be harmless. Sometime later, Sonic became infected with the [[Metal Virus]], a [[Zombot]]-producing virus created by Eggman, who had his memories restored by [[Doctor Starline|Dr. Starline]]. In spite of the incoming pandemic, Sonic managed to cure himself and save the world from the [[Deadly Six]]'s attempt to use the Zombot hordes to destroy the world, but he had to join forces with his enemies to succeed. In the aftermath, Sonic went missing for a while by accidentally ending up in [[Sol Dimension|Blaze's dimension]]. However, he returned in time to save his friends from Eggman. Over the next period, Sonic would clash with Dr. Starline, Eggman, and the Deadly Six.
