{{Nihongo|'''Shadow the Hedgehog'''|シャドウ・ザ・ヘッジホッグ|Shadō za Hejjihoggu}} is a character that appears in the [[Sonic the Hedgehog series|''Sonic the Hedgehog'' series]]. Characterized by his sharp attitude and strong sense of purpose, Shadow is a recurrent arch-rival of [[Sonic the Hedgehog]], whom he resembles and with whom he shares many abilities. His trademark power is [[Chaos Control]], which allows him to warp time and space using a [[Chaos Emerald]].<ref name="SA2B p7">{{Cite manual|game=Sonic Adventure 2: Battle|system=Nintendo GameCube|region=United States|page=7}}</ref><ref name="SegaUS">{{Cite web|publisher=[[Sega/Sega of America|Sega of America]]|url=http://www.sega.com/sonic/globalsonic/post_allabout.php?article=soniccharacters|archiveurl=https://web.archive.org/web/20050305082053/http://www.sega.com:80/sonic/globalsonic/post_allabout.php?article=soniccharacters|accessdate=26 October 2017|work=Sonic Characters|archivedate=5 March 2005|title=Shadow the Hedgehog|quote=Shadow is the spitting image of sonic except for his black body.

Shadow is the "'''Ultimate Life Form'''", created aboard the [[Space Colony ARK]] over fifty years ago by Professor [[Gerald Robotnik]]. He is the final result of [[Project Shadow]], a government experiment that was only completed by infusing Shadow with the DNA of the alien [[Black Doom]]. After his birth, Shadow befriended Gerald's granddaughter, [[Maria Robotnik|Maria]]. However, the [[Guardian Units of Nations]] (G.U.N.) deemed the ARK a threat and raided it, resulting in the captures of Shadow and Gerald, and the death of Maria. Driven to madness, Gerald altered Shadow's memories to one day seek revenge.     

Shadow remained in stasis for decades until he was freed by Gerald's grandson, [[Doctor Eggman]]. Initially motivated by vengeance, Shadow fought Sonic and friends until his true memories of Maria were restored, inspiring him to help save the world from Gerald's doomsday plot. However, Shadow fell to [[Earth]] and lost his memories as a result. Shadow  would only learn the truth of his existence once he stopped the [[Black Arms]] invasion of Earth. He has fought for Maria's wish of peace ever since, acting as a dark hero who protects the Earth and all its inhabitants.

==Concept and creation==
Shadow was conceived as part of the development of ''[[Sonic Adventure 2]]'', which aimed to build on the success of ''[[Sonic Adventure]]''. The game's director, [[Takashi Iizuka]], wanted to explore the dichotomy of [[Wikipedia:Good and evil|good and evil]], leading to the creation of characters that would challenge the established heroes and assist [[Doctor Eggman]].<ref name="Summer">{{cite web |author=Paul.STR337 |title=Summer of Sonic 2011: Sonic Team on Stage |url=https://www.sonicstadium.org/2011/07/sos-2011-stage-interview-barrels-brown-sonic-and-crash-bandicoot-discussed/ |publisher=Sonic Stadium |date=18 July 2011 |accessdate=23 July 2023}}</ref><ref name="Rivals 2 Interview" /> One of these characters was Shadow, while the other became [[Rouge the Bat]].

[[File:Shadow_Concept_Pg188_1.png|thumb|305x305px|left|One of the most famous early designs of Shadow, then known as "Terios".|alt=Concept artwork of a dark gray anthropomorphic hedgehog with an unhappy expression and a muscular torso. He has an ivory scar over his left eye which partially obscures it, long spines on the back that arc downwards, gray skin, and a red right eye. He wears gray gloves with a vertical white line in the middle and golden cuffs, similarly colored boots, and a red neckerchief.]]
The initial idea for Shadow was to create an anti-hero who would contrast sharply with [[Sonic the Hedgehog|Sonic]]. Inspired by American comic book anti-heroes such as [[Wikipedia:Spawn (character)|Spawn]], Shadow was envisioned as a character who would match Sonic in coolness.<ref name="Windii"/><ref name=":0">{{Cite web |date = 7 July 2024 |title = Stream Archive: Anime Expo 2024 - Sonic X Shadow Generations Dark Beginnings Panel |url = https://youtu.be/bgzLocJ8_Hw?si=lFPsK-Pcd6FNik3b |work = YouTube |accessdate = 9 July 2024 |quote = '''[[Takashi Iizuka]]''' (translated by the panel's translator): So Shadow was really born in 1999, when we began development on ''Sonic Adventure 2''. In the beginning, we kind of thought, 'we want a rival character, something to really contrast Sonic, so we need a rival character in this game.' At that time, all of the team flew over to America, and we started living and working in America. When we got there we realized dark heroes, heroes like Spawn, were really popular in America. And that really inspired us to make Shadow a different kind of character, and that's when we thought 'we don't want him to be a rival to Sonic, we want him to be a dark hero.' And that's really where Shadow was born, from an idea.}}</ref> Various early designs of Shadow ranged from having long spines with tufts of fur in front of his eyes to sporting capes, shades, or even a missing eye.

The final design was developed by [[Shiro Maekawa]], who considers himself Shadow's creator and feels a deep personal connection to the character. Maekawa struggled coming up with his personality. One night, while he was brainstorming lines for a scene in which Sonic confronts Shadow for impersonating him, Maekawa came up with Shadow's first line: "''Hmph, aren't you'' [Sonic] ''the fake one here?''".<ref group="note">This line was used in the final version of ''Sonic Adventure 2'', translated into English as "''Hmph. Aren't you the fake hedgehog around here?''"</ref> To further shape his "subtle" character, Maekawa envisioned Shadow would refer to himself with the more humble [[Wikipedia:Japanese pronoun|Japanese pronoun]] {{Nihongo|''boku''|僕}} in that language.<ref name="Sega6">{{cite web |title=006:前川 司郎 |url=http://sonic.sega.jp/SonicChannelOld/creators/006/index.html |website=[[Sonic the Hedgehog]] |publisher=[[Sega]] |accessdate=23 July 2023 |archiveurl=https://web.archive.org/web/20160308142010/http://sonic.sega.jp/SonicChannelOld/creators/006/index.html |archivedate=8 March 2016 |language=Japanese}}</ref>

Shadow was initially only intended to appear in ''Sonic Adventure 2'', which ended with his apparent death. During the development of ''[[Sonic Heroes]]'', there were internal meetings at [[Sega]] regarding whether Shadow (and characters such as [[E-102 Gamma]]) should stay dead or return.<ref>{{Cite web|url=https://x.com/mizuhano/status/989707353237868544|title=@mizuhano on Twitter|date=April 26, 2018|author=[[Shiro Maekawa]]|quote=It was tumultuous between the opposing "Shadow DID die" faction and "DIDN'T" faction.

[[File:ShadowsStoryShadowandGerald.jpg|thumb|left|225px|Shadow being created by [[Gerald Robotnik]], from ''[[Shadow Generations]]''.|alt=Professor Gerald Robotnik stands outside of a capsule, observing an unconscious Shadow the Hedgehog.]]
Fifty years ago, Shadow was created on the [[Space Colony ARK]] by [[Gerald Robotnik]], and grew up there alongside the professor's ailing granddaughter, [[Maria Robotnik|Maria]]. Gerald created Shadow to be the Ultimate Life Form as part of the secretive [[Project Shadow]]. However, a series of tragedies befell the ARK. One day, the military organization [[GUN]] executed a cover-up operation on the ARK, leading to Maria's death and Gerald's arrest and execution. Shadow was captured and put into stasis on [[Prison Island]].<ref>{{Cite game|dev=[[Sonic Team]]|date=October 22, 2024|game=Sonic X Shadow Generations|system=Nintendo Switch|pub=[[Sega]]|language=English|cutscene=Shadow's Story}}</ref><ref name=":1">{{Cite game|dev=[[Sonic Team]]|date=October 22, 2024|game=Sonic X Shadow Generations|system=Nintendo Switch|pub=[[Sega]]|area=[[Collection Room]] - Shadow's History|language=English}}</ref><ref name=":022">{{Cite book|date=22 October 2024|title=[[Gerald Robotnik's Journal]]|author=[[Ian Flynn]]|publisher=Sega}}</ref>[[File:Sonic2app_2016-09-24_15-26-13-103.png|thumb|225px|Shadow first encountering Sonic, from ''[[Sonic Adventure 2: Battle]]''.|alt=In-game screenshot of a Sonic Adventure 2: Battle cutscene, depicting Shadow, with a Chaos Emerald, running past Sonic in downtown Central City.]]
Fifty years later, Prof. Gerald's grandson, [[Dr. Eggman]], freed Shadow to use him as his ultimate weapon. Shadow agreed to help, secretly driven by an intense desire for revenge. His true goal was to assemble the [[Chaos Emeralds]] to power the ARK's [[Eclipse Cannon]] and destroy the world. However, [[Sonic the Hedgehog]] and friends stood in his way. Although the Eclipse Cannon was disabled, a backup plan was activated; Gerald's posthumous confession played, revealing he tampered with Shadow's memories and the ARK itself, as the ARK was set on a crash course with Earth. [[Amy Rose]] pleaded with Shadow to help avert the disaster, and her words awakened his true memories: that Maria wanted the people of the world to be safe and happy. Shadow raced to aid Sonic in saving the world. After an epic struggle with the [[Biolizard]], the Earth was saved, but Shadow fell from space and seemingly perished.<ref name=":1" /><ref>{{Cite game |dev=[[Sega Studio USA|Sonic Team USA]] |date=23 June 2001 |game=Sonic Adventure 2 |system=Dreamcast |pub=[[Sega]]}}</ref>

Eventually, [[Rouge the Bat]] broke into one of Dr. Eggman's bases in search of a great treasure, only to find Shadow sealed in a stasis capsule, along with [[E-123 Omega]]. Once Shadow was awoken, he had no memory of recent events. He wanted to find Eggman and get answers, Rouge still wanted Eggman's treasure, and Omega wanted revenge for being sealed away. United by a common goal, the three agreed to work together and hunt down Eggman. During the hunt, Shadow reunited with Sonic and came across [[Shadow Android|Shadow Androids]] that looked just like him. Shadow began to wonder if he was truly himself or another one of these copies. At the end of the adventure, Rouge entered Eggman's vault, finding hundreds of androids. She too wondered if the Shadow she had awoken was a copy, but Omega pointed out that the androids must have been copied from an original. Shadow set out to find his own answers and a new meaning for his existence.<ref name=":1" /><ref>{{Cite game |dev1 = [[Sonic Team USA]] |date = 6 January 2004 |game = Sonic Heroes |system = Nintendo GameCube |pub = [[Sega]]}}</ref> In another adventure, Shadow encountered [[Emerl]], an ancient weapon of mass destruction who had also been a subject of Gerald Robotnik's research on the ARK.<ref>[[Sonic Team]] (27 February 2004).

With no memory or purpose, Shadow lost interest in the Earth and humanity. His search for direction was interrupted as the Earth was invaded by the [[Black Arms]]. Their leader, [[Black Doom]], appeared before Shadow and ordered him to collect the Chaos Emeralds. Shadow felt no loyalty to Black Doom, but assumed he held answers, so he set out to find the Emeralds and regain his memory. Throughout his efforts, Shadow remembered his promise to Maria to protect the world. He also learned that Prof. Gerald had used Black Doom's DNA to create him, not as a loyal soldier, but as an ultimate weapon to defeat the aliens. In a final struggle, Shadow used the Chaos Emeralds to defeat Black Doom and end the alien invasion. With his original mission complete, he wished to put his past behind him.<ref>{{Cite game |dev=[[Sega Studio USA]] |date=18 November 2005 |fullgame=[[Shadow the Hedgehog (game)|Shadow the Hedgehog]] |system=PlayStation 2 |pub=[[Sega]]}}</ref><ref name=":1" />

Next, Shadow and Rouge were commissioned by GUN to steal the [[Scepter of Darkness]] from Dr. Eggman. During a confrontation, the relic was broken, releasing the time-traveling spirit [[Mephiles the Dark]]. Mephiles took on a new form by inhabiting Shadow's shadow, then banished Shadow and Rouge to 200 years into the [[Silver's future|future]]. There, Shadow witnessed a burning apocalypse and his own future self sealed away. Mephiles revealed humanity blamed Shadow for the Earth's state and imprisoned him, offering a chance at revenge, but Shadow rejected him. Shadow returned to the present, and planned to use the Scepter of Darkness to seal Mephiles once more. However, Mephiles had grown too powerful and could no longer be contained. Eventually, Mephiles realized his goal and reunited with [[Iblis]], becoming the time-destroying god [[Solaris]]. Shadow, along with Sonic and [[Silver the Hedgehog]], used the Chaos Emeralds to obtain their [[Super transformation|super forms]] and stop Solaris. In the end, Solaris was wiped from existence, and Shadow lost all memory of the encounters with Mephiles.<ref name=":1" /><ref name=":2">{{Cite game |dev1 = [[Sonic Team]] |date = 25 October 2024 |game = Sonic X Shadow Generations |system = PlayStation 4 |pub = [[Sega]]}}</ref> In other adventures, Shadow faced [[Eggman Nega]] on two occasions, joining Sonic, Silver, and even Dr. Eggman in thwarting the mad doctor's plans.<ref>{{Cite game |dev1 = Backbone Entertainment |dev2 = [[Sega Studio USA]] |date = 24 November 2006 |game = Sonic Rivals |system = PlayStation Portable |pub = [[Sega]]}}</ref><ref>{{Cite game |dev1 = Backbone Entertainment |dev2 = [[Sega Studio USA]] |date = 13 November 2007 |game = Sonic Rivals 2 |system = PlayStation Portable |pub = [[Sega]]}}</ref>[[File:ShadowGenScr1.jpg|thumb|225px|Shadow re-encountering Black Doom, manifesting as [[Doom's Eye]], from ''[[Shadow Generations]]''.|alt=In-game screenshot of Shadow Generations, with Shadow on a past version of the ARK facing Doom's Eye.]]
One night, Shadow began experiencing painful visions of his past. Suspecting the return of the Black Arms, Shadow traveled to the ARK, indeed finding Black Doom. However, Dr. Eggman's latest minion, the [[Time Eater]], suddenly pulled Shadow into [[White Space]]. There, he began to be tormented by Black Doom and infused with new [[Doom Powers]]. Shadow also met the time-displaced Maria and Gerald Robotnik. With their encouragement, Shadow came to accept his past, harnessing his Doom Powers to defeat Black Doom once more. After saying goodbye to his family, Shadow went on to encourage Sonic in the battle against the Time Eater.<ref name=":2" />

At some point, Shadow invaded one of Dr. Eggman's bases. Along the way, he fought the mercenary team [[Jackal Squad]] and their leader, [[Infinite]]. Shadow easily defeated Infinite, leaving him feeling weak and humiliated. After being implanted with a copy of the [[Phantom Ruby]], Infinite became Eggman's elite agent, conquering the world and targeting Shadow's allies. Infinite also used the powers of the Phantom Ruby to create a [[Phantom Copy]] of Shadow to fight Sonic. Shadow eventually intervened, destroying the copy and joining Sonic's efforts to liberate the world. He was on the front lines, helping lead the charge to defeat Eggman's phantom army and save the world.<ref name=":1" /><ref>{{Cite game |dev1 = [[Sonic Team]] |date = 7 November 2017 |game = Sonic Forces |system = Nintendo Switch |pub = [[Sega]]}}</ref>
==Personality ==
[[File:Shadow profile SG.png|thumb|left|225px|Shadow's profile, from the [[Xbox 360]] version of ''[[Sonic Generations]]''.]]
Being [[Sonic the Hedgehog|Sonic]]'s polar opposite personality-wise,<ref name="SonicCity" /> Shadow is, bluntly put, a brooding loner. He usually acts with a cool and businesslike indifference, only occasionally showing his vulnerable side. He is rarely seen with others for an extended period of time and usually distances himself from essentially everyone. He is usually blunt and does not speak much, but he always knows exactly what to say in combat. However, Shadow never bluffs; if he makes a threat, he has every intention of carrying it out. Tying into this attitude, the Japanese script has his self-pronoun be the more humble "boku", with his pronoun for others switching between either "kimi" or "omae" depending on his mood.

As the most violent and merciless character in the series at times,<ref name="SonicCity">{{cite web|title=Sonic City|url=http://www.sonic-city.com/en/characters/shadow/index.html|publisher=[[Sega]]|archiveurl=http://web.archive.org/web/20080229035720/http://www.sonic-city.com/en/characters/shadow/index.html|archivedate=29 February 2008}}</ref> Shadow's ruthlessness and aggression leads to enemies never treating him lightly. Alongside his dark and violent demeanor, Shadow can be smug and stubborn. He usually treats others in a very callous manner, throwing in his opinion no matter how cold-hearted it is and not caring for whatever the response is. Shadow is also shown to have a sharp wit; during the [[Space Colony ARK]] [[Sonic Adventure 2|incident]], after being called a faker by Sonic, he replied that the latter was not worth being considered his fake.<ref>{{Cite game|dev=[[Sega Studio USA|Sonic Team USA]]|date=23 June 2001|game=Sonic Adventure 2|system=Dreamcast|publisher=[[Sega]]|cutscene=[[Sonic Adventure 2/Script (Dark)#Face off with Sonic|Face off with Sonic]]|quote='''Shadow''': That blue hedgehog again, of all places... / '''[[Sonic the Hedgehog|Sonic]]''': I've found you, faker! / '''Shadow''': Faker? I think you're the fake hedgehog around here. You're comparing yourself to me? Ha! You're not even good enough to be my fake!}}</ref>

Just like how Shadow's motivations are never simple to understand, he spends as much time grappling with his own inner demons as he does with his rival, Sonic.<ref name="SonicCity" /> In the past, Shadow has had a degree of mental instability, in particular post-traumatic stress disorder. This was demonstrated by his instances of post-traumatic flashbacks to [[Maria Robotnik|Maria]]'s face prior to and during the events of the [[Black Arms]] [[Shadow the Hedgehog (game)|incident]], though it could be argued that the instances of the latter game were simply an effect of his amnesia. On one occasion, at the time of the Space Colony ARK incident, seeing police sirens flashing caused him to intensely flash back to the massacre aboard  Space Colony ARK and in particular Maria's death. Even prior to the events of the ARK raid, Shadow demonstrated some degree of self-doubt, most notably expressing frustration over how, despite being created as the Ultimate Lifeform specifically to act as a means to cure various maladies, he is still unable to cure his friend Maria, and also admitted to Maria when she desired living on Earth that he's uncertain whether he even has a place on the planet.<ref>''[[Sonic X Shadow Generations: Dark Beginnings]]'' Episode 1: "[[Shadow and Maria]]"</ref> Similarly, largely because of his being created with Black Arms DNA, Shadow during this time also showed signs of self-loathing, to the extent that he even went as far as to view himself as no different in overall nature to the Death Leech in containment before being reassured by Maria that he does ultimately have a heart.<ref>''[[Sonic X Shadow Generations: Dark Beginnings]]'' Episode 2: "[[Finding the Way]]"</ref> Shadow was soon able to overcome this in the Black Arms and the [[Emerl]] [[Sonic Battle|incidents]], during which he chose to move on from the past yet keep Maria in his heart. In fact, his personal journey since being awoken by [[Doctor Eggman|Eggman]] has had him confront the shackles of his past, such as ties, fate, and memories. Since then, it appears as though he is reaching a point where he can "do as his heart desires" in his own way.<ref name="SonicXShadow">{{cite web|url=https://sonic.sega.jp/SonicChannel/special/coverstory/20210628_002603/|title=ソニック & シャドウ|author=[[Sega]]|publisher=[[Sonic Channel]]|date=28 June 2021|accessdate=28 June 2021|archiveurl=https://web.archive.org/web/20210628073207/https://sonic.sega.jp/SonicChannel/special/coverstory/20210628_002603/|archivedate=28 June 2021|language=Japanese}}</ref>

Shadow originally had disdain for [[Human|humanity]], being a misanthrope, but rarely attacked them outright, merely looking at them as a distant observer. During the events of the Space Colony ARK incident, Shadow was planning to destroy the [[Earth|planet]] both ordered by [[Gerald Robotnik]] through brainwashing, and as revenge for the death of his only friend, Maria Robotnik. Shadow eventually moves past his hatred for humanity by remembering his promise to Maria. Later on, Shadow decided to protect humanity and those on earth to honor Maria's dying wish despite their original misgivings. Now, Shadow has moved on from the past and decided to protect humanity on his own accord. He does, however, have some lingering guilt over Maria's death, to the extent that he at least once came close to having intrusive visions of a scenario where Maria didn't die before reminding himself that chance ended a long time ago.<ref>''[[Sonic X Shadow Generations: Dark Beginnings]]'' Episode 3: "[[To the ARK]]"</ref>

During the many incidents that Shadow takes part in, he pursues his foes with a relentless, unwavering determination. He will usually go to any length to accomplish something he desires or feels should be a certain way, no matter what the cost. Before the [[War to Take Back the Planet]], it is heavily implied that Shadow ruthlessly massacred an entire mercenary band known as the [[Jackal Squad]] not only in an extremely dismissive, nonchalant manner (as he did not even remember the incident a few months later), but also seemed slightly proud, mocking the mercenary defense squad by saying they themselves needed a defense squad. He also demonstrated rather coarse language during the Black Arms incident.

Shadow possesses a strong sense of identity; after falsely being told by Rouge that he was not the Ultimate Lifeform due to a [[Project Shadow|lab report]], he stated to her that, even if his memories were fake, he was still Shadow the Hedgehog.<ref>{{Cite game|dev=[[Sega Studio USA|Sonic Team USA]]|date=23 June 2001|game=Sonic Adventure 2|system=Dreamcast|publisher=[[Sega]]|cutscene=Cutscene 28|quote='''[[Rouge the Bat|Rouge]]''': Do you actually believe that... you're the real Shadow? / '''Shadow''': No doubt. / '''[[Rouge the Bat|Rouge]]''': Even your memories might not be real, you know? / '''Shadow''': Even if my memories are not real, it's still me; Shadow. And I will fulfill my promise to Maria. That's the only thing that matters to me now}}</ref> These qualities make him rarely susceptible to being manipulated by others.

In Shadow's own words, he is not interested in peace, nor does he care about what happens to others. In truth, he simply does not like it when foolish people do whatever they please. While this may make it seem like Shadow stands firmly in opposition to villainy, he is actually very indiscriminate about who he faces, as he chooses to stand against anyone who he condemns for being "foolish", be they villains like Dr. Eggman or heroes like Sonic. He similarly does not want thanks for the help he provides when he does something heroic, believing that showing gratitude is a waste of time.<ref name="SonicXShadow" /> However, the grim and uncaring disposition he puts on is not entirely accurate considering the lengths he goes to save others including even sacrificing his own life. In contrast to his words, Shadow acts in a way that ultimately protects others. Deep down he cares about those around him, only hiding his more caring side to keep himself shielded and distant. Despite his apathetic nature, he does feel sympathy for others, and since reforming himself at the end of the Space Colony ARK incident, he has fought for the greater good, most noticeably to prevent letting other people experience past tragedies, specially the ones that he has been through.<ref>[[Sonic Team]] (27 February 2004).

[...] His hope was that no matter how crazed and obsessed with destruction mankind might became, the weapons themselves would never fight. Shadow, you are afraid of your own power. It troubles you. But, you've never used your power recklessly. You've never used it selfishly. Gerald's wishes have come true."</ref> Once, he also saw himself as a weapon since he was created as one, thus causing him to believe that he and other weapons would eventually have to be destroyed to achieve world peace.<ref>[[Sonic Team]] (27 February 2004).

Shadow was often depressed about the loss of Maria, which is why he keeps to himself, but his relationship with her is obvious as he goes to great lengths to protect the planet and keep her dream of peace and prosperity alive. He also maintains a strong bond with his teammates, Rouge and [[E-123 Omega|Omega]], proving that while his attitude makes him seem like a careless person, he does have compassion, more than he otherwise lets on. Still, Shadow brushes off most kindness or sympathy that is sent his way; during the [[Neo Metal Sonic]] [[Sonic Heroes|incident]], when Rouge showed concern for Shadow when he saw a broken [[Shadow Android|android]] of himself, suspecting [[Team Dark]]'s Shadow might be an android too, Shadow curtly brushed her concern away. During the Black Arms incident, after Sonic suggested some "friendly competition", Shadow bluntly rejected his offer.<ref>{{Cite game|dev=[[Sega Studio USA]]|date=15 December 2005|fullgame=[[Shadow the Hedgehog (game)|Shadow the Hedgehog]]|system=Nintendo GameCube|pub=[[Sega]]|cutscene=After [[Westopolis]] (Hero mission)|quote='''[[Sonic the Hedgehog|Sonic]]''': Now that was sweet, Shadow! / '''Shadow''': Yeah...

Another instance is during the aborted [[Solaris]] [[Sonic the Hedgehog (2006)|incident]], when Rouge told him that she would always be by his side, he acknowledged her.[[File:Shadow fast friends bio.jpg|thumb|225px|Shadow's bio for [[Fast. Friends. Forever.]]]]Despite the fact that Shadow often fights for the greater good, he is considered an anti-hero for the most part due to his morality and means to his desired end goals. He does whatever is necessary to get what he wants or feels is right, though this enthusiasm causes him to take risks and jump into situations without fully thinking them through.<ref>{{Cite book|author=Pedigree Books|title=[[Sonic the Hedgehog Super Interactive Annual 2014]]|publisher=Pedigree Publishers|page=15|chapter=Eggman's IQ Math Test|date=August 2013|isbn=978-1908152077|quote=Fact: Shadow often launches into situations without fully thinking them through.

The two of us can handle this just fine."</ref> Regardless, Shadow does have his moments of selflessness and heroism; he nearly sacrificed his life at the end of the Space Colony ARK to save the [[earth]], and helped [[Silver the Hedgehog|Silver]] uncover the truth of the [[Solaris Project]] after saving Sonic from him in an aborted timeline.
In spite of Shadow's serious and no-nonsense attitude he is occasionally willing to spend time doing leisurely activities or social events like celebrating [[The Murder of Sonic the Hedgehog|Amy's birthday]] at a murder mystery party on the [[Mirage Express]]. He even got Amy a present along with participating in the murder mystery event. Shadow has also competed in a variety of racing and sports competitions, having a strong competitive spirit.[[File:ShadowsOwnReasons.jpg|thumb|252x252px|left|Shadow talking with [[Rouge the Bat|Rouge]], from [[IDW Sonic the Hedgehog Issue 9|''Sonic the Hedgehog'' #9]].]]
Best described as a grim anti-hero, Shadow has a strong sense of purpose and pursues his goals by any means necessary. He possesses a willingness to do whatever it takes to achieve these goals once he has set his sights on them, including using lethal force. This natural vehemence, however, tends  to blind him with anger and make him prone to reckless decisions.<ref name="StH102">[[IDW Sonic the Hedgehog Issue 10|''Sonic the Hedgehog'' #10]], "The Battle for Angel Island, Part 2"</ref><ref name="StH5">[[IDW Sonic the Hedgehog Issue 5|''Sonic the Hedgehog'' #5]], "The Fate of Dr. Eggman, Part 1"</ref> It can also cause him to hold grudges, to the point where, if the object of his grudge is in sight, he is blinded to everything else; after being bested by [[Doctor Starline|Starline]] at the [[White Park Grand Chateau]], Shadow decided to chase after him while ignoring not only Rouge and Tails being captured, but also an avalanche that would have injured or even killed everyone else. However, Shadow ultimately worked with Sonic to try to stop the avalanche.<ref name="StH36">[[IDW Sonic the Hedgehog Issue 36|''Sonic the Hedgehog'' #36]], "Chao Races and Badnik Bases, Part 4"</ref>  He also does not tend to take others into consideration, and sometimes his desire for revenge overwhelms his own sense of safety. Being an anti-social lone wolf, Shadow is generally not in favor of team-ups either; although he may occasionally cooperate with others, it is typically for his own reasons and does not guarantee that he is willing to follow orders.<ref name="StH102" /><ref name="StH9">[[IDW Sonic the Hedgehog Issue 9|''Sonic the Hedgehog'' #9]], "The Battle for Angel Island, Part 1"</ref> He also often leaves without saying goodbye or thanks.<ref name="StH62">[[IDW Sonic the Hedgehog Issue 6|''Sonic the Hedgehog'' #6]], "The Fate of Dr. Eggman, Part 2"</ref><ref name="StH11">[[IDW Sonic the Hedgehog Issue 11|''Sonic the Hedgehog'' #11]], "The Battle for Angel Island, Part 3"</ref>

Shadow is sharp-witted, brooding, arrogant, and always seems to be on edge. He usually acts with a cool and business-like indifference, preferring to stay quiet and only speak when it is necessary to achieving his goals without opening up to anyone while staying focused on his intended target. When push comes to shove, however, Shadow can quickly become enormously aggressive and extensively ruthless. He also does not tend to hold back against anyone, especially against those who get in his way.<ref name="StH5" /> Additionally, he is stubborn and prideful to the point of foolhardiness and never runs away from a fight; while he and Sonic were defending [[Sunset City]] from a horde of [[Zombot]]s, Sonic ran off to burn his [[Metal Virus]] infection into remission while advising Shadow to do the same should he get infected, only for Shadow, who considered running to be a coward's tactic (and believed himself to be wholly immune to the Metal Virus), to continue fighting, which sealed his fate upon being infected by the virus.<ref name="StH192">[[IDW Sonic the Hedgehog Issue 19|''Sonic the Hedgehog'' #19]], "Crisis City, Part 1"</ref>

Beside Chaos Control, Shadow is able to use a number of additional chaos powers. One of these chaos powers include his [[Chaos Spear]] technique, in which he throws up to several bolts of [[Chaos Emerald energy]] at his opponent that can either paralyze or injure an opponent, depending on its power level. Shadow's most powerful technique, however, is the [[Chaos Blast]], a chaos power where he releases a discharge of Chaos Emerald energy in a massive explosion that eliminates everything within a range of 10-20 yards.<ref name="ShadowCActions" />
[[File:Heroes BlackTornado.png|left|thumb|225px|Shadow's signature [[Black Tornado]] attack in ''[[Sonic Heroes]]''.]]
One of Shadow's main offensive maneuvers is the [[Spin Attack]], a technique where he curls into a concussive ball or cutting disk and directs himself at his targets. With it, Shadow can shred or burrow through just about any substance given enough speed. Highly adept in its usage, Shadow can utilize several variants of the Spin Attack for both grounded and aerial maneuvers, including the [[Spin Dash]], [[Spin Jump]], [[Double Jump]], [[Homing Attack]], [[Air Dash]], [[Somersault]], [[Dark Spin Dash]] and the [[Light Speed Attack]], which attacks at the speed of light.

Even without his Spin Attack, Shadow is a powerful hand-to-hand combatant. In line with his nature and potent abilities, Shadow uses a fighting style where he utilizes strong blows, such as [[Shadow Chop|powerful chops]], [[Kick|flying kicks]], [[Edge Attack|sideways kicks]], [[Shadow Kick|high spin kicks]], [[Shadow B. Kick|reverse spin kicks]], [[Shadow Rocket|downward dive]] [[Shadow Eagle|kicks]], or just [[Chaos Attack|barrages of punches]] [[Attack|and kicks]]. In addition, many of Shadow's stronger hand-to-hand combat moves revolves heavily around his usage of Chaos Control for space distortion effects to knock opponents away and his Air Shoes' [[Shadow Slider|exhaust for burning opponents]].

Shadow is an effective combat strategist, able to make split second calculations or adjustments to succeed in battle. His strategies can range from creative uses of his environment, manipulating his opponent's shortcomings, and outmaneuvering enemies.

As shown during the [[Sonic Free Riders|second EX World Grand Prix]], Shadow is talented with an his [[Extreme Gear]] ([[Darkness]] and [[Black Shot]]). During the tournament, he was able to put up quite a fight and even defeat some of the world's best Extreme Gear riders. When riding on an Extreme Gear, Shadow is skillful enough to ride on Grind Rails, execute complex tricks while in midair, and [[Attacks in the Sonic Riders series|perform]] chaos powers and combat moves with ease.
[[File:Shadow-the-hedgehog--with-motorcycle-min_(1).png|right|thumb|225px|Shadow's [[Dark Rider]], from ''[[Shadow the Hedgehog (game)|Shadow the Hedgehog]]''.]]
Shadow also has extraordinary skill when it comes to driving or piloting all forms of vehicles. Not only is he one of the best race car drivers in the universe with the [[Dark Reaper]], but he is also able to perfectly operate [[Buggy|weaponized buggies]], [[Dark Rider|armed motorcycles]], [[Glider|modified gliders]], [[Hover Craft|hover crafts with machine guns]], [[Jump Vehicle|bipedal mechs]] and [[Air Saucer|alien devices]]. Shadow is as well an expert gunner, capable of using weaponry like the [[Gun Lift|G.U.N. Lift]]s and [[GUN turret|G.U.N. turret]]s with perfect accuracy. Also, whereas Sonic dismisses firearms, Shadow is not above using such weaponry, and has demonstrates proficient skills in a [[Weapons in Shadow the Hedgehog|very wide range of weapons]] during the Black Arms incident, such as close combat weapons, guns, cannons, lock-on weapons and lasers. Shadow may also have some knowledge about machinery, having once been able to fiddle with a deactivated [[E-123 Omega|Omega]] and deduce he was in standby mode.<ref>{{Cite game|dev=[[Sonic Team]]|date=14 November 2006|fullgame=[[Sonic the Hedgehog (2006)|Sonic the Hedgehog]]|system=Xbox 360|pub=[[Sega]]|cutscene=Omega located (Shadow Episode)}}</ref> A miscellaneous ability Shadow has demonstrated as well is telekinesis, which is potent enough to let him move an [[Extreme Gear]] around with his mind with ease.<ref>{{Cite game|dev=[[Sonic Team]]|date=21 February 2006|game=Sonic Riders|system=Nintendo GameCube|pub=[[Sega]]}}</ref>

[[File:ShadowWithoutLimiters.png|thumb|left|225px|Shadow using his full power, from [[Sonic the Hedgehog (2006)|''Sonic the Hedgehog'' (2006)]].]]
As powerful as he is, Shadow is able to make himself stronger up tapping into an even greater power within himself. This power is so potent that should he remove his [[Limiter Ring]]s, he becomes a walking dynamo of raw power. Eggman compares the overall output of the resulting energy from the rings' removal to that of a raging furnace in his log.<ref name="Shadow101">{{Cite web|url=https://youtu.be/1KhKd1bj7G0?si=lSkjGLXrSvcpzk53|work=[[Wikipedia:YouTube|YouTube]]|publisher=Sonic the Hedgehog|title=Shadow 101: A Brief History of Shadow the Hedgehog|date=11 July 2024|accessdate=11 July 2024|quote='''[[Doctor Eggman|Dr. Eggman]]''': Second item of note: Shadow's Limiter Rings.

Shadow is an extremely powerful individual and combatant, capable of going toe-to-toe with and sometimes even overwhelming [[Sonic the Hedgehog|Sonic]] in fierce combat. He boasts superb agility and reflexes to match his rocket skate-induced speed, allowing him to act accordingly to even Sonic's split-second movements. Like Sonic, he can perform the [[Spin Attack]], a technique where he curls into a concussive ball or cutting disk and directs himself at his targets. With it, Shadow can shred or burrow through just about any substance given enough speed.<ref name="StH6">[[IDW Sonic the Hedgehog Issue 6|''Sonic the Hedgehog'' #6]], "The Fate of Dr. Eggman, Part 2"</ref> Likewise, although he can only keep up with Sonic's level of super speed using his rocket skates, he is still faster than the average person, enough to chase after a speeding truck.<ref name="StH20">[[IDW Sonic the Hedgehog Issue 20|''Sonic the Hedgehog'' #20]], "Crisis City, Part 2"</ref>[[File:IDW61ChaosControl.png|thumb|left|239x239px|Shadow performing [[Chaos Control (IDW)|Chaos Control]], from [[IDW Sonic the Hedgehog Issue 61|''Sonic the Hedgehog'' #61]].]]In addition, Shadow commands a number of Chaos Powers. He can warp space and time with [[Chaos Control]], which allows him to teleport himself and, with the help of a [[Chaos Emerald]]s, he can teleport others instantaneously over wide distances at will. Chaos Control can alternatively be used to stop time temporarily. Shadow can also form spears out of green energy called [[Chaos Spear|Chaos Spears]] that he can either throw at opponents or wield as a solid melee weapon.<ref name="StH10">[[IDW Sonic the Hedgehog Issue 10|''Sonic the Hedgehog'' #10]], "The Battle for Angel Island, Part 2"</ref><ref name="StH19">[[IDW Sonic the Hedgehog Issue 19|''Sonic the Hedgehog'' #19]], "Crisis City, Part 1"</ref><ref name="StH6" /><ref name="StH59">[[IDW Sonic the Hedgehog Issue 59|''Sonic the Hedgehog'' #59]], "Urban Warfare, Part 3"</ref> When Shadow attacked [[Eggperial City]], he was able to manipulate the [[Giant Fake Chaos Emerald]]s to create a tower of them and to trap Eggman's central tower.<ref name="StH61">[[IDW Sonic the Hedgehog Issue 61|''Sonic the Hedgehog'' #61]], "Urban Warfare, Part 5"</ref> Shadow has impressive hand-to-hand combat skills as well, being able to utilize a mix of brutal punches and kicks, as he was able to beat up even [[Neo Metal Sonic (IDW)|Neo Metal Sonic]], albeit with a surprise attack.<ref name="StH10" />

=== Equipment===
[[File:Hover_Shoes_flying.png|thumb|225px|Shadow using his [[Air Shoes]] to hover, from ''[[Sonic Adventure 2]]''.]]
Shadow wears a pair of specialized shoes called [[Air Shoes]]. These footwear are the primary source of Shadow's speed,<ref name="SR2 manual" /> producing small jet streams that let him hover-skate at speeds supposedly even surpassing [[Sonic the Hedgehog|Sonic]]'s speed.<ref>{{Cite game|dev=[[Sonic Team]]|date=27 February 2004|game=Sonic Battle|system=Game Boy Advance|pub=[[Sega]]|quote='''[[Shadow Run]]''': Shadow's running skill.

Shadow wears four [[Limiter Ring]]s, one on each of his wrists and ankles, that limit the amount of power he uses during combat and other situations. By removing them, Shadow is able to utilize his full power.

During the [[Black Arms]] [[Shadow the Hedgehog (game)|incident]], Shadow made use of a vast selection of [[Weapons in Shadow the Hedgehog|weaponry]]. This included anything from close combat weapons like [[Survival Knife|Survival Knives]] and [[Black Sword]]s; guns like [[Pistol]]s and [[Sub-Machine Gun]]s; cannons like [[Bazooka (Shadow the Hedgehog)|Bazookas]] and [[Grenade Launcher]]s; lock-ons like [[8-Shot RPG]]s and [[Worm Shooter]]s; to lasers like [[Laser Rifle]]s and [[Refractor]]s.

[[File:Super shadow final.png|thumb|left|225px|Shadow [[Super transformation|transformed]] into [[Super Shadow]], from ''[[Sonic Art Assets DVD]]''.]]
By harnessing the power of the seven [[Chaos Emerald]]s, Shadow can enter a [[super transformation|Super State]], transforming him into '''Super Shadow'''. In this state, all of Shadow's abilities far surpass his normal ones and his chaos powers are increased to their full limit. He is also able to fly and is nearly invulnerable. Initially, Shadow found it difficult to stay in this state due to inexperience,<ref>{{Cite game|dev=[[Sega Studio USA|Sonic Team USA]]|date=23 June 2001|game=Sonic Adventure 2|system=Dreamcast|pub=[[Sega]]|area=[[Finalhazard]]|quote='''[[Super Shadow]]''': Gutha!

==Weaknesses==
[[File:Dolphin 2015-09-05 20-34-39-930.png|thumb|225px|Shadow being temporarily controlled by [[Black Doom]], from ''[[Shadow the Hedgehog (game)|Shadow the Hedgehog]]''.]]
Shadow takes extreme measures to achieve his goals.<ref name="Scholastic" />

During the time he had amnesia, Shadow was initially a somewhat easy target for manipulation due to his confusion about who he was and his eagerness to learn anything more about his past. [[Doctor Eggman|Dr. Eggman]] could deceive him with lies about his past and [[Black Doom]] could subtly manipulate him using visions. However, after learning of his true purpose, Shadow is no longer as easily deceived.

Being part of the [[Black Arms]], Shadow is partially an extension of Black Doom, making him vulnerable to mind control exerted by Black Doom himself. However, Shadow can fight this influence through sheer resolve and willpower.

Despite his immortality, Shadow can be knocked down if taken off-guard. Most noticeably, this will leave him unable to walk and speak immediately after the attack.<ref>{{Cite game|dev=[[Sonic Team]]|date=27 February 2004|game=Sonic Battle|system=Game Boy Advance|pub=[[Sega]]|area=[[Gimme Shelter]] (Shadow's Episode)|quote='''[[Rouge the Bat|Rouge]]''': Hey, not bad! / '''[[Guard Robo]]''': ... ... ... an opening! / '''Shadow''': Guh...! / '''Rouge''': Shadow!

Shadow when his [[Limiter Ring|Limiter Rings]] are taken off, if he uses all his energy, it can lead in into him over-exerting himself allowing him to be defeated easily from exhausting him.<ref name="Shadow101" />

While Shadow has no known physical weaknesses, his rash and headstrong nature has caused him to fall to dire situations before; even though Sonic had told him he could similarly counter his infection with his speed, Shadow, misinterpreting it as meaning to retreat, refused to break away from fighting the Zombots. Also, despite the fact that his immune system is indeed more powerful than many others and cannot leave him sick from any known diseases, it is not immune to everything as he still got infected by the [[Metal Virus]], albeit in a more delayed response compared to other people.<ref name="StH194">[[IDW Sonic the Hedgehog Issue 19|''Sonic the Hedgehog'' #19]], "Crisis City, Part 1"</ref>

Shadow is a focused, serious and powerful hedgehog known as the Ultimate Life Form. While trying to join in the fight against Eggman, he ends up trapped inside the Void of the [[Shatterverse]], not allowed to visit other worlds. Shadow must try to find a way to help Sonic, but first, he must learn to trust the hedgehog once again.

===Paramount===
{{Main|Shadow the Hedgehog (Paramount)}}
[[File:S3 movie art Shadow 01.png|thumb|175px|right|Shadow the Hedgehog, from [[Sonic the Hedgehog 3 (film)|''Sonic the Hedgehog 3'' (film)]].]]
In the ''[[Sonic the Hedgehog (film series)|Sonic the Hedgehog]]'' film series produced by [[Paramount Pictures]] and its spin-offs, Shadow is an anthropomorphic hedgehog associated with a secret experiment called [[Project Shadow (Paramount)|Project Shadow]] that took place over fifty years prior to [[Doctor Robotnik (Paramount)|Dr. Robotnik]]'s [[Sonic the Hedgehog 2 (film)|return]] from the [[Mushroom Planet]].

===IDW Publishing===
{{Main|Shadow the Hedgehog/History and appearances (IDW)}}
[[File:IDWShadowTheHedgehog.png|thumb|175px|left|Shadow the Hedgehog, from  [[IDW Sonic the Hedgehog Issue 5|''Sonic the Hedgehog'' #5]].]]
In the ''[[Sonic the Hedgehog (IDW comic series)|Sonic the Hedgehog]]'' comic series and its spin-offs published by [[IDW Publishing]], Shadow's past is virtually identical to his game counterpart's, up until after the events of ''[[Sonic Forces]]''. After the [[War to Take Back the Planet|Eggman War]], Shadow focused on  finding [[Doctor Eggman|Dr. Eggman]] and eliminating him. He eventually found him in [[Windmill Village]], where [[Sonic the Hedgehog|Sonic]] defended Eggman, claiming he had lost his memory and was now harmless. After some persuasion, Shadow decided to leave Eggman be. He later took part in the battle for [[Angel Island]] and the fight against [[Neo Metal Sonic]]. Afterward, during the [[Metal Virus]] outbreak, Shadow, along with [[Team Dark]], helped evacuate [[Sunset City]]. However, Shadow ended up getting infected with the Metal Virus and turned into a [[Zombot]]. Eventually, however, he was restored to normal on Angel Island, where he immediately began pursuing Eggman, but was foiled by [[Metal Sonic]]. He later followed a lead on Eggman to [[White Park Zone]], where he got attacked by [[Doctor Starline|Dr. Starline]]. Soon after, Shadow helped Sonic save the [[White Park Grand Chateau]] from an avalanche caused by Starline.

===CoroCoro===
{{Main|Shadow the Hedgehog (CoroCoro)}}
[[File:ShadowCoroCoroManga.png|thumb|175px|left|Shadow the Hedgehog, from  [[The Jet Black Hedgehog: Shadow the Hedgehog]].]]
In the ''[[The Jet Black Hedgehog: Shadow the Hedgehog]]'' [[manga]] series published by [[CoroCoro Comic]], Shadow's past is substantially different. He is an aggressive, and violent, yet stoic hedgehog who after suffering an identity crisis for being a failed cure for [[Maria Robotnik|Maria]]. Earth's National Defense Forces, being manipulated by death leeches, raid the Space Colony ARK, disposing of everything including Maria. After heartfelt words from Maria, Shadow gets sent down by an emergency escape pod and teleports into [[White Space]], in which he meets a mysterious creature known as [[Bug-Eye]], who promises to bring Maria back to life as long as Shadow collects the [[Three Wishing Orbs]].
