{{nihongo|'''Knuckles the Echidna'''|ナックルズ・ザ・エキドゥナ|Nakkuruzu za Ekiduna}} is a character that appears in the [[Sonic the Hedgehog series|''Sonic the Hedgehog'' series]]. He is an anthropomorphic [[echidna]] and the current guardian of the [[Master Emerald]], a powerful ancient gemstone which is kept on [[Angel Island]].

Knuckles is an anthropomorphic echidna with red fur that covers most of his body, a black nose on his peach-skinned muzzle, a white crescent-shaped patch of fur on his chest, sharp teeth, (only visible when he is smirking or angry earlier) and amethyst eyes. He also has seven dreadlock-like spines around the sides and back of his head and a medium-sized, tri-crooked tail. For attire, Knuckles wears red and yellow shoes with green cuffs, light gray soles, and metallic, sextuple-bolted plates on top. He also wears large, white, mitten-like gloves with sock-like cuffs and two pointy, spiked knuckles on each hand.

In his younger years, Knuckles had black eyes, a more protruding chest, more defined cheekbones, and was shorter in stature.

==History==
:''Note: This is an abbreviated look at Knuckles' history, focusing primarily on his three most recent mainline adventures. For a complete history of Knuckles, see [[Knuckles the Echidna/History and appearances]]. For his history in the IDW comics and Sonic Prime, see [[Knuckles the Echidna/History and appearances (IDW)]] and [[Knuckles the Echidna/History and appearances (Sonic Prime)]].''
===Past===
Born and raised alone on [[Angel Island]]<ref name="SegaUSKnuckles"/><ref name="Sonic 3 JP"/>, Knuckles assumed the mantle of the [[Master Emerald]]'s guardian, fiercely protecting both it and the island from intruders.<ref name="Sonic 3 JP"/> Despite protecting the Master Emerald out of duty, Knuckles ultimately was unaware of his ancestral roots to the [[Knuckles Clan]], or the fate of the other [[Echidna]]s.<ref name="SonicxKnuckles">{{Cite web |url=http://sonic.sega.jp/SonicChannel/topics/special/coverstory/20210118_002454/ |title=ソニック ＆ ナックルズ |author=[[Sega]] |publisher=[[Sonic Channel]] |accessdate=27 January 2021 |archiveurl=https://web.archive.org/web/20210120085440/http://sonic.sega.jp/SonicChannel/topics/special/coverstory/20210118_002454/ |archivedate=20 January 2021 |language=Japanese}}</ref> One day, however, he faced a catastrophe when [[Doctor Eggman|Dr. Eggman]]'s [[Death Egg]] craft  crashed into the island, sending it plummeting into the ocean. Soon after, Eggman himself emerged, and took advantage of Knuckles' confusion to convince him that a hedgehog named [[Sonic the Hedgehog|Sonic]] and a fox named [[Miles "Tails" Prower|Tails]] were after the Master Emerald for nefarious purposes.<ref name="Sonic 3 JP"/> When Sonic and Tails did inevitably arrive on the island in search of adventure, the tricked echidna attempted to halt their progress on several occasions, until Eggman made his true plans known by stealing the Master Emerald himself when Knuckles' back was turned. Realizing his error, Knuckles teamed up with his former enemies, and assisted Sonic and Tails their pursuit of Eggman. After the heroes succeeded and the Death Egg was destroyed, Knuckles parted with Sonic and Tails, who left the island on good terms with the echidna. From this point forward, Knuckles became a friendly rival to Sonic, assisting him in many more of his adventures.

===''Sonic Forces''===
During the [[Infinite]] [[Sonic Forces|incident]], Knuckles experienced a visit from [[Silver the Hedgehog]], who warned him of an incoming catastrophe that could potentially destroy the world. After witnessing subsequent paranormal events, Knuckles left his position on Angel Island to assist those in danger on the world below. <ref>''[[Sonic Forces: Stress Test]]'', "Stress Test"</ref> During Sonic's disappearance and the following [[War to Take Back the Planet]], Knuckles became the head of the [[Resistance]], and desperately fought to keep a small portion of the world free from the influence of the [[Eggman Empire]] and their living superweapon, [[Infinite]]. Knuckles' efforts would serve him when a talented [[Avatar|rookie]] joined the Resistance, and ultimately freed Sonic from his imprisonment on the rebuilt Death Egg. With Sonic and the Rookie's help, Knuckles was able to lead the resistance into slowly reclaiming the world's territories, and ultimately a final assault on the [[Eggman Empire Fortress]] which resulted in the defeat of both Eggman and Infinite, and the full liberation of the planet.

===''Team Sonic Racing''===
During the [[Dodon Pa]] [[Team Sonic Racing|incident]], Knuckles and the rest of [[Team Sonic]] received mysterious invitations to an interplanetary racing tournament, and, out of curiosity, accepted them. Soon, Knuckles learned that the founder and organizer of the race was a mysterious bureaucrat known only as "Dodon Pa", who had invited many other teams to the prix as well, providing an advanced vehicle to each of them. As the race carried on, and the competition between teams became more aggressive, Knuckles grew suspicious of Dodon Pa's ultimate motives, a suspicion only magnified when he learned that Dodon Pa possessed the technology to send messages to [[Sol Dimension|other dimensions]], and even [[Silver's future|the future]]. At the climax of the prix, however, Knuckles learned that Dodon Pa's real motives were to create an [[Ultimate Energy Engine]] from the race's data, which he planned to use for philanthropic purposes. Unfortunately, the engine was stolen by Eggman, prompting Knuckles and the other teams to fight back, successfully saving Dodon Pa and destroying the unstable engine.

===''Sonic Frontiers''===
During the [[Starfall Islands]] [[Sonic Frontiers|incident]], Knuckles found himself pulled from Angel Island's [[Sky Sanctuary]] after investigating a mysterious [[Portal (Sonic Frontiers)|structure]]. Emerging on the Starfall Islands, Knuckles was immediately set upon by a troop of [[Soldier]]s, which he handily defeated with his strength. However, the battle drew the attention of another being in the area: [[Sage]], the newest creation of Dr. Eggman. Knuckles attempted to face the malicious AI, but Sage used the powers of an [[Asura]] [[Guardian (Sonic Frontiers)|Guardian]] under her control to imprison Knuckles inside a [[Cyber Cage]] on the desert [[Ares Island]].<ref>{{Cite web |author=Sonic the Hedgehog |date=1 November 2022 |title=Sonic Frontiers Prologue: Divergence |url=https://www.youtube.com/watch?v=_gjszHTDjzo |publisher=YouTube}}</ref> Furious, Knuckles remained in the cage until Sonic the Hedgehog arrived, having visited the island on his own quest. Knuckles was freed by Sonic, but was left in a ghostlike state as a result of still being partially connected to [[Cyber Space]]. Knuckles repaid his debt to Sonic by assisting the hedgehog in his search across the island for the remaining [[Chaos Emerald]]s. In the process, he learned much about the island and the fate of its [[Ancients|natives]], while also confiding with Sonic about being restrained from exploring the world by his dedication to guarding the Master Emerald. Although Knuckles was eventually freed from his non-physical state through the efforts of Sonic, the act infected the hedgehog with a deadly amount of [[Cyber corruption]], and as a result Knuckles willingly returned to his ghost form in order to mitigate the damages, and allow Sonic to focus on solving the problem himself. Once [[Super Sonic]] and a reformed Sage ultimately defeated [[The End]], the cosmic being that was behind the entire crisis, Knuckles was freed from Cyber Space, and returned to his physical form once more, celebrating the victory alongside [[Amy Rose|Amy]] and [[Miles "Tails" Prower|Tails]]. 

In an [[Sonic Frontiers/The Final Horizon|alternate version]] of the crisis's conclusion Knuckles instead continued to assist Sonic after sacrificing his physical form, working with Tails, Amy, Eggman, and Sage to locate the Chaos Emeralds scattered across [[Ouranos Island]]. Battling his way through enhanced Guardian robots, and destroying any [[Impact Form]]s that impeded progress, Knuckles helped deliver the Emeralds to Sonic, and later assisted Super Sonic during his final fight with the modified [[Supreme]] [[Titan (Sonic Frontiers)|Titan]], possessed by none other than The End itself.

Regardless of which depiction of the final battle actually took place, following The End's defeat, Knuckles rendezvoused with his victorious teammates preparing to leave the island on board the [[Tornado]]. As the four heroes flew off into the horizon, Knuckles vowed to return to his duty as guardian of Angel Island "at least, for a while".

==Personality==
[[File:CS K US.png|thumb|left|225px|Knuckles' profile, from ''[[Sonic Jam]]''.]]

As such, he cares very little about what others think, which makes him bluntly honest, straightforward, and somewhat egotistical.<ref name="HeroesProfile" />

Knuckles is fiercely loyal to [[Angel Island]] and does whatever is in his power to protect it. He prefers to stay close to the [[Master Emerald]]'s [[Altar of Emerald|shrine]] to keep a watchful eye over everything at his home. Despite this devotion, the echidna is willing to leave his duty whenever his help is needed.<ref name="TailsTube3" /> Though he has found other lifestyles appealing, and may even dream of a free one like [[Sonic the Hedgehog|Sonic]]'s own,<ref name="HeroesProfile" /> he will never trade away his duties as he is far too devoted to his role as guardian, looking very concerned whenever he leaves the Master Emerald behind and spending too much time protecting the giant gem alone.<ref name="StationLIVE">{{Cite web |author=SEGA Asia(EN) |date=23 May 2022 |title=Sonic Station LIVE! - April broadcast summary |url=https://www.youtube.com/watch?v=gwSJ8gXXTDM |publisher=YouTube |accessdate=21 January 2023}}</ref> When not performing his duties, Knuckles prefers spending his time practicing his fighting skills, going treasure hunting, or hanging out with his friends.

Knuckles is usually solemn, stoic, and collected, and usually likes to be by himself. As stubborn as he is tough,<ref name="FreeRidersProfile" /> he is as well headstrong and inflexible,<ref name="HeroesProfile" /> preferring to do things his way, which causes him to clash with others. Regardless, he is very strong-willed, seldom wavering in his determination, and will not give up on his goals once he has set them. While he is cool and determined in battle, the echidna has an extremely short and wild temper and is hard to reason with when he is angry,<ref>[[Sonic Team]], [[Dimps]] (15 November 2005). ''[[Sonic Rush]]''. [[Nintendo DS]]. [[Sega]]. Area/level: World Map ([[Sonic the Hedgehog|Sonic]]). "'''[[Sonic the Hedgehog|Sonic]]''': You know, when Knuckles is angry...

[[File:Knuckles profile SG.png|thumb|225px|left|Knuckles' profile, from the [[Xbox 360]] version of ''[[Sonic Generations]]''.]]
Despite being a silent loner, Knuckles is a heroic, brave, kind-hearted, and selfless soul. While unwilling to forgive evil people,<ref name="JPSHeroes">{{Cite web|url=http://sonic.sega.jp/sonic_heroes/character.html|title=Official Sonic Heroes website|author=[[Sega]]|publisher=[[Sega]]|work=Characters: Team Sonic|accessdate=25 May 2021|archiveurl=https://web.archive.org/web/20041207144720/http://sonic.sega.jp/sonic_heroes/character.html|archivedate=7 December 2004|language=Japanese}}</ref> he will risk his own life to save anyone or get them out of trouble and shows empathy for others. He is likewise a loyal and caring friend, who is always willing to help his friends out in tight situations and will do anything to protect them. When not angered, the echidna is pretty laid-back and never cracks under pressure. He can also be very understanding of the sly and does not take kindly to people who disrespect or hurt his friends, or innocents, in any way.

Having been living much of his life in isolation, Knuckles grew up believing in honesty and holds a firm and steadfast belief that there is good in everyone, which always lets him give people second chances. Because of his lack of social ingenuity, however, it makes him very naive, incredibly gullible, fast about forgiving people, and easily misled, which has given him a history of being tricked by [[Doctor Eggman|Dr. Eggman]]. This has made the echidna aggressive and suspicious towards anyone he deems questionable. Over time, however, Knuckles has gotten better about this and is more suspicious concerning the doctor's trickery. Once he finds out he has been tricked, he can get quite angered, but quickly regains enough of his composure to start working towards a resolution immediately.

Though not dull-witted, Knuckles is often prone to rash and ill-advised actions. While not above picking complex strategies, he often chooses force to be the solution, pushing himself through obstacles while focusing on his goal and ignoring other factors along the way. Similarly, he can also be quite reckless when panicking about the Master Emerald, such being especially evident during the [[Space Colony ARK]] [[Sonic Adventure 2|incident]], where he ended up fighting Sonic for the controls of the space shuttle and causing it to crash land as well as abandoning his allies out of a panic due to the Master Emerald shards being lost to space from a collision with a meteor forcing the cargo bay to open. When in his right element, however, Knuckles can be quite clever, sharp-witted, and sneaky, such as setting several successful traps for Sonic and [[Miles "Tails" Prower|Tails]] on Angel Island when they first arrived. He is also capable of learning from his mistakes. Knuckles has also proven himself to have a high degree of leadership skills, most noticeably during his time as the commander of the [[Resistance]]. He is noted to be very charismatic with inspirational speeches, and he has a flair of [[Operation Big Wave|daring plans]] that provided the Resistance with a much-needed offensive during the [[War to Take Back the Planet]]. However, for all his skills as a leader, Knuckles is still easily distracted and prefers to be out on the battlefield rather than in the command center. While he would never admit it, Knuckles has become a bit envious of the lifestyle that Sonic has, being able to live carefree without anything holding him in one place. Even so, Knuckles would never trade away his duties to live Sonic's life, far too devoted to his role as guardian. 

Knuckles is said to be shy around women.<ref>''[[Sonic Jam]]'' ([[Sega Saturn]]) [[:File:CS K US.png|Knuckles the Echidna profile]].</ref> Also, due to his secluded lifestyle on Angel Island, Knuckles feels very uncomfortable in industrialized or crowded cities and places,<ref>[[Sonic Team]] (23 December 1998). ''[[Sonic Adventure]]''. [[Dreamcast]]. [[Sega]]. Area/level: [[Station Square (Sonic Adventure)|Station Square]]. "'''Knuckles''': I hate big cities."</ref><ref>[[Sonic Team]] (23 December 1998).

Knuckles seems to have lightened up on later adventures, such as the [[Time Eater]] [[Sonic Generations|incident]] and the War to Take Back the Planet. While he still sometimes displays a brooding, headstrong, and stubborn attitude, he is shown to be better at acknowledging his shortcomings and displays more personal restraint and better social interaction.[[File:TheIDWKnux.png|thumb|Knuckles the Echidna, from [[IDW Sonic the Hedgehog Issue 3|''Sonic the Hedgehog'' #3]].|left]]

In the IDW Comics, Knuckles is a tough and headstrong echidna. Serious, unconcerned with nonsense, and stubborn, he has no patience for stationary work and prefers to be where the action is, unless the safety of the [[Master Emerald]] is at stake. Despite this, he is still an overall nice person in normal conversations.<ref name="StH3" />Knuckles prefers solitude. He is likewise fiercely defensive and loyal to [[Angel Island|his homeland]] and prefers to stay there.<ref name="StH3">[[IDW Sonic the Hedgehog Issue 3|''Sonic the Hedgehog'' #3]], "Fallout, Part 3"</ref> Because of this, he refuses to let anyone else protect it, determined to do his job alone.<ref name="StHAnnual2022s1">''[[Sonic the Hedgehog Annual 2022]]'', "Guardians"</ref><ref>{{cite web|url=https://www.youtube.com/watch?v=lrODh4kmz3c&feature=youtu.be|title=BumbleKast Q&A for November 16th, 2020|work=YouTube|date=16 November 2020|accessdate=16 November 2020}}</ref> As such, when anything bad befalls the island and its Master Emerald, Knuckles takes it very personally and blames himself for not being able to prevent it.

As such, he has been known to open his island to the needy and defend those instead of the Master Emerald, just like he promised [[Espio the Chameleon|Espio]] during the [[Zombot]] apocalypse. He is also ready to make sacrifices for the good of all, as seen when he let himself get infected by the [[Metal Virus]] in order to keep a Zombot [[Shadow the Hedgehog|Shadow]] at bay.<ref name="StH29">[[IDW Sonic the Hedgehog Issue 29|''Sonic the Hedgehog'' #29]], "All or Nothing, Part 4"</ref>

==Powers and abilities==
Being the guardian of the [[Master Emerald]], Knuckles is a very powerful, seasoned warrior. Said to be an unstoppable power in fights,<ref name="JPSHeroes" /> he is capable of taking on even the most powerful of opponents without rest. He has even been able to fight figures like [[Sonic the Hedgehog|Sonic]], [[Rouge the Bat|Rouge]], [[Shadow the Hedgehog|Shadow]], [[Silver the Hedgehog|Silver]], and [[Metal Sonic]] to a standstill.

[[File:Heroes VolcanicDunk.png|thumb|225px|Knuckles punching the ground with enough force to trigger an [[Fire Dunk|eruption]], from ''[[Sonic Heroes]]''.]]
Knuckles' trademark ability is his indomitable strength. Possessing lots of power,<ref name="SBattlePower" /> he is strong enough to pulverize massive boulders,<ref name="SonicCity" /><ref name="SC" /><ref name="SHOpening" /> punch through solid steel,<ref name="SonicCity" /> and lift objects several times his size and weight with ease.<ref name="SonicCity" /> By comparison, Knuckles' strength is stated to equal Sonic's speed;<ref name="SonicCity" /> considering the hedgehog's measured footspeed, which is known to surpass Mach 1, it would mean that Knuckles is capable of lifting over 100 metric tons.<ref group="note">'''Calculation: Knuckles' strength predicated on Sonic's running''':<br />A 100-ton object requires a force that is at least equal to 1,000,000 newtons
:Force x distance = Work = Energy
To figure out the number of joules Sonic produces when moving Mach 1, we use the Kinetic Energy formula, which is 1/2 x M X V^2; thus 0.5 x 35
:(Sonic's mass in kilograms) x 340^2 (Mach 1), which would be equal 2,026,452 joules
Work needed to lift a 100-ton object for a distance of 2 meters is also 2 million joules, therefore, if Knuckles' strength is equal to Sonic's speed, then he should have enough energy to lift a 100-ton object 2 meters.</ref> This makes the echidna one of the physically strongest characters in the series.<ref name="SonicCity" /> His strength seems to lie in his upper body, particularly in his arms and fists, the former of which boasting enormous strength<ref name="AdventureJPManual">''[[Sonic Adventure (original version)|Sonic Adventure]]'' ([[Dreamcast]]) Japanese instruction booklet, pg. 24.</ref> and latter being as hard as rocks.<ref name="SR2">''[[Sonic Rivals 2]]'' ([[PlayStation Portable]]) United States instruction booklet, pg. 7.</ref> Another testament to Knuckles' strength is that by just punching the ground, he can create fissures, [[Hammer Punch|widespread tremors]], and even [[Volcanic Dunk|powerful volcanic eruptions]].<ref>''[[Sonic Heroes]]'' ([[PlayStation 2]]) United States instruction booklet, pg. 18.</ref> Additionally, he can [[Spiral Upper|punch]] with his fists or [[Fire Dunk|throw objects through the air]] with such force that they ignite from friction.

He is even able to run fast enough to create [[Boost Mode|afterimages of himself]] and scale vertical surfaces and ceilings. Even so, he is not quite as fast as Sonic at his maximum speed, as Knuckles is noted to [[Knuckles Run|run fairly slow]] by comparison. Knuckles is also fast enough to execute rapid punches in quick succession within a split-second,<ref>[[Sonic Team]] (21 February 2006). ''[[Sonic Riders]]''. [[Nintendo GameCube]]. [[Sega]].

[[File:Chara06 01.jpg|thumb|225px|Knuckles [[Glide|gliding]], from [[Sonic the Hedgehog (2006)|''Sonic the Hedgehog'' (2006)]].]]
Unlike Sonic, Knuckles is a good [[swim]]mer, being able to swim into incredible depths and with both great speed and skill. Thanks to the spikes on his fists, he is also a skilled burrower,<ref name="S&SASR" /> being able to [[dig]] like a gopher<ref name="SonicCity" /> into any wall or floor and tunnel through subterranean regions at great speed.<ref>[[Sonic Team]] (11 November 2011). ''[[Sonic Generations]]''. [[PC]]. [[Sega]]. Area/Level: [[Knuckles: Horde of Enemies]].</ref> These spikes also make him a skilled climber,<ref name="S&SASR" /> as they allow him to plant his fists into any surface and [[Climb|scale]] them. In addition, the echidna is an expert at [[Glide|gliding]],<ref>[[Sonic Team]], [[Sega Studio USA|Sonic Team USA]] (27 February 2004). ''[[Sonic Battle]]''. [[Game Boy Advance]]. [[Sega]]. "'''[[Grinder Attack]]''' - Knuckles's air action. He's an expert at gliding."</ref> which he can easily do by using his dreadlocks.<ref name="SonicCity" /><ref name="S&SASR" />

Knuckles possesses the uncanny ability to sense energy, specifically the [[Chaos Emerald energy|one]] produced by the [[Chaos Emerald]]s and the Master Emerald or similar ones, such as those contained in the [[Sol Emerald]]s.<ref>[[Sonic Team]] (27 June 2003).

(Are there gems here akin to the Sol Emeralds?)"</ref> and can track down their "[[Emerald Radar|signals]]" like an [[Emerald Detector]]. Like Sonic and [[Shadow the Hedgehog|Shadow]], Knuckles can also harness the power of the Chaos Emeralds to empower himself. As its guardian, Knuckles is also the only person alive who knows how to control the Master Emerald,<ref name="SC" /> which allows him to utilize the jewel's different powers or tap into its vast energies to [[Knuckles' All-Star Move|empower himself]]. Other more mystical abilities Knuckles has exhibited include [[Thunder Arrow|summoning lightning bolts]], harnessing Earth elementals to [[Knuckles Heal|heal]] himself,<ref>[[Sonic Team]], [[Sega Studio USA|Sonic Team USA]] (27 February 2004). ''[[Sonic Battle]]''. [[Game Boy Advance]]. [[Sega]]. "'''[[Knuckles Heal]]''' - Knuckles' heal skill.

''[[Sonic Battle]]''. [[Game Boy Advance]]. [[Sega]]. "'''[[Meteor Crush]]''' - Knuckles' air shot. He makes rocks fall from the sky using the supernatural power of the earth."</ref>

Knuckles is also able to perform the Spin Attack, a technique where he curls into a concussive ball or cutting disk and directs himself at his targets. With it, Knuckles can shred or burrow through just about any substance given enough speed. Adept in its usage, Knuckles can utilize several variants of the Spin Attack for both ground- and aerial maneuvers, including the [[Spin Dash]], [[Spin Jump]], and [[Homing Attack]].

[[File:Rivals 2 Load screen 04 (no text) - Attack.png|thumb|left|225px|Knuckles fighting [[Sonic the Hedgehog|Sonic]], from ''[[Sonic Rivals 2]].'']]
Even without his Spin Attack, Knuckles is a skilled hand-to-hand combatant. A master in a number of martial arts<ref name="HeroesProfile">''[[Sonic Heroes]]'' ([[PlayStation 2]]) United States instruction booklet, pg. 5.</ref> focusing on hand-to-hand combat, Knuckles makes use of his powerful fists to take on his foes, with his specialty lying in [[Punch Attack|punching moves]] where he uses his spiked fists for devastating blows. In terms of fighting style, Knuckles focuses on power, using [[Kn. Straight|straight]], [[Knuckles Chop|repetitive]] and [[Megaton Hook|forceful punches]], such as [[Double Punch|power-packed jabs]] or [[Knuckles Upper|piercing uppercuts]] to deal critical blows to his opponents. For stronger strikes, Knuckles tends to [[Megaton Hook|build up momentum with his fists by swinging them around]], before hitting his opponent in full force. By taking advantage of his burrowing abilities, Knuckles can even hide underground before [[Major Eruption|hitting opponents with an uppercut]] from below when his opponent least expects it. Despite being a powerhouse, however, most of Knuckles' fighting moves are slow and easy to read.<ref name="SBattlePower" />

[[File:SFProlouge 56.png|thumb|220x220px|Knuckles climbing a wall and searching in ''[[Sonic Frontiers Prologue: Divergence]]''.]]
Knuckles is an expert treasure hunter and can be considered one of the best in the world, if not the best.<ref>[[Sonic Team]] (3 May 2002). ''[[Sonic Adventure 2: Battle]]''. [[Nintendo GameCube]]. [[Sega]]. "'''[[Sonic the Hedgehog|Sonic]]''': We're counting on you buddy! The world's greatest treasure hunter!"</ref> Also, while not highly intelligent, Knuckles is well-versed in ancient cultures, ruins, and legends, such as when he was able to translate the ancient [[Babylonians|Babylonian]] texts at [[Gigan Rocks]] during the [[MeteorTech]] [[Sonic Riders: Zero Gravity|incident]].

Knuckles is also a skilled [[Extreme Gear]] rider, having proven himself a worthy competitor against many of the world's best Extreme Gear riders. To best put his skills in perspective, Knuckles was able to beat [[Storm the Albatross]] in a race, who is regarded as a "wind master". When riding his Extreme Gear, Knuckles can bash his way through obstacles effortlessly and engage in close combat with his fellow racers without losing control. With his Extreme Gear, Knuckles can even enhance his physical abilities.<ref>''[[Sonic Free Riders]]'' ([[Xbox 360]]) United States instruction booklet, pg. 10.</ref>

When it comes down to it, Knuckles is also shown to have semi-competent leadership skills. During the [[War to Take Back the Planet]], he was able to lead the [[Resistance]] for several months against the [[Eggman Empire]] and even come up with [[Operation Big Wave|war strategies]] of his own. 

As seen during [[Dodon Pa]]'s [[Team Sonic Racing|Grand Prix]], Knuckles has excellent skills when it comes to driving and racing in racecars like the [[Land Breaker]]. Along those lines, Knuckles has also demonstrated some rudimentary piloting knowledge of more advanced crafts, having once piloted the [[Egg Saucer]],<ref>[[Sonic Team]], [[Dimps]] (3 February 2002). ''[[Sonic Advance 2]]''. [[Game Boy Advance]]. [[THQ]]. Area/Level: [[Sky Canyon]] Boss Attack.</ref> and a Space Shuttle from Eggman's base to the [[Space Colony ARK]] (albeit in a more dangerous manner for half the journey due to panic over losing his [[Emerald Shard]]s).<ref>[[Sonic Team]] (3 May 2002). ''[[Sonic Adventure 2: Battle]]''. [[Nintendo GameCube]]. [[Sega]]. Cutscene: Cutscene 1 (Last Story). "'''[[Sonic the Hedgehog|Sonic]]''': Heh, just letting Knuckles pilot the shuttle all the way over here, was more dangerous than you could ever be!"</ref>

===Equipment===
Although he prefers to let his fists do the talking, Knuckles has wielded a number of tools during his adventures, albeit never permanently. During the [[Emerl]] [[Sonic Battle|incident]] for example, he made use of [[Mole Bomb|deployable]] [[Air Mole Bomb|landmines]], and amidst the [[Gemerl]] [[Sonic Advance 3|incident]], he would wield his own version of the [[Piko Piko Hammer]].

In the IDW Comics, Knuckles possesses incredible strength, being as strong as [[Sonic the Hedgehog|Sonic]] is fast; with a single punch, he is able to pierce thick metal with ease or knock a person into the ground.<ref name="StH92">[[IDW Sonic the Hedgehog Issue 9|''Sonic the Hedgehog'' #9]], "The Battle for Angel Island, Part 1"</ref><ref name="StH292">[[IDW Sonic the Hedgehog Issue 29|''Sonic the Hedgehog'' #29]], "All or Nothing, Part 4"</ref> Thanks to his experience, he is able to make good use of this skill. By stretching his arms and legs outwards while airborne, Knuckles can also catch the air under his dreadlocks to ride on it, allowing him to glide through mid-air. Also, by using the spikes on his fists, Knuckles can deal extra damage to his targets and scale any kind of surface with ease. He is also a great hand-to-hand combatant.<ref name="StH3"/><ref name="StH11">[[IDW Sonic the Hedgehog Issue 11|''Sonic the Hedgehog'' #11]], "The Battle for Angel Island, Part 3"</ref>

Being the guardian of the [[Master Emerald]], Knuckles possesses a special link to the massive gem. This link allows him to detect the energies and will of the Master Emerald, although this link can be disturbed.<ref name="StH8">[[IDW Sonic the Hedgehog Issue 8|''Sonic the Hedgehog'' #8]], "Silent Support"</ref><ref name="StH9"/>

===Transformations===
====Super Knuckles====
{{Main|Super Knuckles}}
[[File:Knucklessupershield.png|thumb|200px|right|Super Knuckles, from ''[[Sonic Heroes]]''.]]
With the seven [[Chaos Emerald]]s, Knuckles is able to attain a Super State known as '''Super Knuckles'''. In this state, all of Knuckles' abilities far surpass his normal ones. In addition, he is able to fly and is virtually invulnerable. However, this transformation consumes a lot of energy and requires [[Ring]]s to be maintained.

====Hyper Knuckles====
{{Main|Hyper Knuckles}}
[[File:Hyper Knuckles animated.gif|thumb|left|Hyper Knuckles, from ''[[Sonic 3 & Knuckles]]''.]]
In ''[[Sonic 3 & Knuckles]]'', Knuckles can transform into an extended version of Super Knuckles, called '''Hyper Knuckles''', with the seven [[Super Emerald]]s. This form basically shares the same abilities and powers as Super Knuckles but on an even higher level.

====Color Powers====
{{Main|Color Power}}
By harnessing different variants of [[Hyper-go-on]] from [[Wisp]]s, Knuckles can use specific '''Color Powers''' to transform into a certain form, such as a drill, a laser, or even a planet, each one possessing its own unique abilities. So far, Knuckles has been able to transform into the [[Cyan Laser]], [[Yellow Drill]], and [[Indigo Asteroid]]. However, these transformations require a steady supply of Hyper-go-on to be maintained.

==Weaknesses==
Knuckles is stubborn and short-tempered,<ref name="Scholastic" /> yet he can be easily fooled. He also has a degree of short-sightedness as well, as during the Chaos Incident, he mistook a Chaos Emerald for an Emerald Shard after seeing a glint in Eggman's hand, with Eggman exploiting this weakness by implying Sonic was also hunting for Emerald Shards, leading to a fight between him as well as Tails and Sonic after he saw a glint in their hands.

He is shy around the girls.<ref>''[[Sonic Jam]]'' ([[Sega Saturn]]) [[:File:CS K US.png|Knuckles the Echidna profile]].</ref>

Knuckles suffers from phasmophobia (fear of ghosts), as he was scared of [[King Boom Boo]] during the [[Space Colony ARK]] [[Sonic Adventure 2|incident]], though evidently not to any debilitating extent, as he was perfectly capable of engaging in combat with the latter after only a brief spell of unease.

{{Main|Knuckles the Echidna/History and appearances (Sonic Prime)}}
[[File:SPrimeKnuckles.png|thumb|left|150px|Knuckles in ''[[Sonic Prime]]''.]]
Knuckles is one of Sonic's best friends. Due to the [[Paradox Prism]]'s incident, Knuckles is displaced across different dimensions from the [[Shatterverse]]. His alternate counterparts are: [[Renegade Knucks]] from [[New Yoke City]], [[Gnarly Knuckles]] from [[Boscage Maze]], and [[Knuckles the Dread]] from [[No Place]].

===Paramount===
{{Main|Knuckles the Echidna (Paramount)}}
[[File:Knuckles TV series - Knux Artwork.png|thumb|225px|Knuckles, from [[Knuckles (TV series)|''Knuckles'' (TV series)]].]]
In the ''[[Sonic the Hedgehog (film series)|Sonic the Hedgehog]]'' film series produced by [[Paramount Pictures]] and its spin-offs, Knuckles is an alien [[Echidna (Paramount)|echidna]] who is the last of his kind and is seeking out the [[Master Emerald (Paramount)|Master Emerald]], a gemstone of great power created by the echidnas but was later confiscated by the [[owl]]s due to its dangerous power. To gain a clue to the Master Emerald's whereabouts, Knuckles began to search for the [[Sonic the Hedgehog (Paramount)|Sonic the Hedgehog]], who was the apprentice of the final owl, [[Longclaw]]. In his search, he discovered [[Doctor Robotnik (Paramount)|Dr. Robotnik]], who lead him to Earth and promised to help him find the Master Emerald. However, Robotnik later betrayed Knuckles and took the Master Emerald for himself. Due to this, Knuckles teamed up with Sonic and [[Miles "Tails" Prower (Paramount)|Tails]] to recover the Master Emerald. The trio formed a pact to protect it and Knuckles went on to live with them and the Wachowskis on Earth.

===IDW Publishing===
{{main|Knuckles the Echidna/History and appearances (IDW)}}
[[File:KnucklesIDW.png|thumb|left|Knuckles, from [[IDW Sonic the Hedgehog Issue 3|''Sonic the Hedgehog'' #3]].]]
In the ''[[Sonic the Hedgehog (IDW comic series)|Sonic the Hedgehog]]'' comic series and its spin-offs published by [[IDW Publishing]], Knuckles' past is virtually identical to his game counterpart's, up until after the ''[[Sonic Forces]]''. After the [[War to Take Back the Planet|Eggman War]], Knuckles remained in command of the [[Resistance]], but most of his duties were handled by [[Amy Rose|Amy]]. Knuckles would also help eliminate the dispersed [[Badnik]] groups and, with the help of [[Sonic the Hedgehog|Sonic]], recapture [[Barricade Town]]. It later turned out that [[Neo Metal Sonic]] had taken control of the [[Eggman Empire]] and conquered [[Angel Island]], allowing him to acquire the [[Master Emerald]]. Together with his friends, Knuckles defeated Metal Sonic and regained his island where he chose to remain. He decided as well to announce the Resistance's dissolution. Later, during the [[Metal Virus]] pandemic, Knuckles had to let Sonic and the members of the [[Restoration]] onto his island and defend them from the [[Zombot]]s. After the Zombot apocalypse was resolved, Knuckles chose to remain on his island.

==Reception==
The character has received generally positive attention. According to IGN, fans "seemed legitimately happy" with the addition of the character of Knuckles, who was popular enough to get marquee billing in ''[[Sonic & Knuckles]]'', but the writer felt that characters that came after him were going "overboard." IGN's Colin Moriarty singled out the introduction of both Knuckles and Tails as when the series became "iffy" and listed them and all other characters in the series, sans Sonic and Robotnik, as being 2nd most in need to "die" on his top 10 list. In contrast, he was listed as the best ''Sonic'' character by Official Nintendo Magazine based on the impact he brought to the ''Sonic'' games in which he first appeared.

Complex listed Knuckles as their eleventh most wanted character in the next ''Super Smash Bros.'' game. In another article, Complex regarded Knuckles as a better character than Sonic, and praised his gliding and climbing abilities, stating "even if his levels were a little more challenging than Sonic's, the thrill of being able to explore certain parts of levels that the blue-colored hero could not was worth it". Game Rant included Knuckles on their list of "Top 10 Third-Party Characters that Could Appear in the New ''Super Smash Bros.''", commenting "This punch-drunk brawler knows how to serve up a buffet of knuckle sandwiches, and there's no question that he's one of the most fitting characters to occupy a spot on the roster".

Mega Zone's review of ''[[Knuckles' Chaotix]]'' praised the introduction of a new protagonist, whom it deemed "rougher [and] tougher" in comparison to the "spineless" Sonic. Mean Machines Sega called Knuckles' powers "impressive" and the character overall more useful and promising than Tails. ''Sega Magazine'' stated that Knuckles "looks cooler" than Sonic, comparing him to Spider-Man, and suggested he be given his own game. They later called him "groovy" and "ace", concluding that they "love him."

According to official [[Sonic Team]] polls, Knuckles is the fourth most popular character in the series, behind [[Miles "Tails" Prower|Tails]], [[Shadow the Hedgehog|Shadow]] and [[Sonic the Hedgehog|Sonic]].<ref>{{Cite web|url=http://sonic.sega.jp/SonicChannel/event/016/002.html |archiveurl=https://web.archive.org/web/20131004221142/http://sonic.sega.jp/SonicChannel/event/016/002.html |author=Sonic Channel| title=Official Popularity Poll results |date=23 June 2006 |archivedate=4 October 2013 |language=Japanese}}</ref>
