Shadow the Hedgehog

Shadow the Hedgehog (シャドウ・ザ・ヘッジホッグ, Shadō za Hejjihoggu), is both a fictional character and deuteragonist from the Super Kingdom Bros.' Sonic series created by Yuji Naka. He is a dark doppelgänger, immortal, anthropomorphic hedgehog/Black Arm hybrid and the arch-rival of Sonic the Hedgehog. Shadow was created as the "Ultimate Life Form" (究極生命体, Kyūkyoku Seimeitai) by Gerald Robotnik, using the DNA of Black Doom, and is the end result of Project Shadow. His purpose was to provide ways to develop a cure for incurable deadly illnesses, more specifically for Gerald's granddaughter Maria Robotnik, but he was captured and put into stasis on Prison Island by the military when he was deemed as a threat to humanity.

Fifty years later, Shadow was released by Dr. Eggman in order to enlist him in his plan to conquer the world. Initially, Shadow worked with him but secretly sought to destroy the planet in order to avenge Maria, who had been killed by the military, but was persuaded to save it from Gerald's doomsday plans. In the process, Shadow lost his memories and as such, sought to uncover the truth of his past, during which he met Black Doom and the Black Arms; in the end, Shadow regained his memories, uncovered the truth, and thwarted Black Doom's agenda and saved the world. From there, he continued his mission to protect humanity by becoming a special agent of GUN.

Shadow is sharp-witted, always on edge, and has a strong sense of purpose, willing to accomplish his goals by any means. Essentially a dark version of Sonic, Shadow can match him in both speed and skill, and can use Chaos Control with a Chaos Emerald. While preferring to work alone, he has helped Sonic and his allies when needed.

"If the world chooses to become my enemy, I will fight like I always have."

Personality
Best summarized as a grim anti-hero, Shadow has a strong sense of purpose, practically to the point of stubbornness, and pursues his goals by any means necessary with a willingness to do whatever it takes to get what he wants, being willing to go as far as to take another person's life to ensure others' safety. This natural vehemence tends to make him launch himself into situations without fully thinking them through. Nonetheless, he is never shown to feel regret about his actions. He is also a lone wolf and is not big on team-ups; although he will go along with others for his own reasons, this does not guarantee that he is willing to follow orders.

Extremely sharp-witted, Shadow is brooding and always seems to be on the edge, and he usually acts with a cool and businesslike indifference. He is normally quiet and will not speak unless it is necessary to achieving his goals. When push comes to shove, however, Shadow can quickly become extremely aggressive and extensively ruthless. He is also not one to pull his punches for anyone, especially against those who get in his way.

Despite his apathetic nature, Shadow is not completely heartless, although he tries to bury such feelings and thoughts inside of him. For example, when out to kill a seemingly reformed Dr. Eggman, Shadow ultimately choose to give the doctor a chance to prove his benevolence after being reminded of how he himself had turned over a new leaf after trying to destroy Sonic and the world at large.

Abilities and Powers
Shadow is easily one of the most powerful characters in the series. He is extremely fast, capable of matching Sonic's and move at such velocity that he releases yellow energy discharges in his wake that he can use against enemies. As examples of his speed, Shadow could move both Molly and Rouge away from a large explosion in less than a second and can even dodge laser barrages. He is also very agile and has incredible jumping skills that allows him to jump hundreds of meters into the air. Furthermore, Shadow can use his vast super speed even in space, attacking and moving freely, something even Sonic cannot do.

Shadow has a significant degree of physical strength as he could push back against one of Final Mova's heads single handed. His body is also able to resist incredible punishment, such as being slammed into solid surfaces and even survive from being struck by powerful laser cannons or by Sonic's charged Spin Attack. By removing his Limiters from his wrists, Shadow can access his full power, which enhances his overall power so drastically that he can single-handedly destroy an entire Metarex fleet. However, using his full power for too long drains his stamina to the point where he will be rendered unconscious.

Shadow is naturally able to tap into the arcane powers of any nearby Chaos Emerald (fake or not) and utilize their chaos energy to empower himself and use a variety of Chaos Powers, and has a special connection to both them and the Master Emerald. In "Shadow Knows", he is seen unleashing a blast of energy to destroy some security robots.

Shadow has fearsome combat skills, as seen in his first encounter with Sonic and during his raid on the Blue Typhoon when he was able to fight his way through a weaken Sonic, Knuckles (though Shadow is shown to struggle when he fought against Knuckles), and Tails. He was also shown fighting his way through a large fleet of Metarex soldiers, destroying them all. In addition, Shadow shows over-average intelligence, such as when fighting Scarship he realized a head-on attack wouldn't work. He then switched for some advanced tactics and instead decided to shake the ship apart from the inside by striking its body at incredible speed.

With just one Chaos Emerald, he can induce Chaos Control to stop time, warp himself through space. He can also create multiple Chaos Spears or merging them to create one slide of chaos energy to increase its attack power. He is also able to use Spin Attack for both offensive and defensive maneuvers, but does not use it to the same extent as Sonic.

Physical Abilities
Shadow is easily capable of matching Sonic's abilities in both speed and power. Although he is not as strong as characters like Knuckles the Echidna, Shadow has superhuman strength; with effort, he can overturn large objects many times his weight and size such as trucks, buses and large slabs of concrete with one hand. Like other characters in the series, Shadow can also move at super speeds, an innate talent that members of the hedgehog species possess, and can evenly match even Sonic's speed as well, who can run at hypersonic speeds. While Shadow's Hover Shoes are credited as the source of his speed, his powerful body allows him to easily rival Sonic's world class speed as well. While there is some inconsistency about how fast the two are compared to each other, Shadow has admitted that Sonic is the faster of the two of them.

Shadow is extremely acrobatic, agile, and an experienced athlete capable of gracefully leaping over any obstacles that head his way and performing various forms of nimble movements. He has radical reaction time to match his movements, being able to react to danger within a split second.

Shadow has incredible resilience to damage, being able to survive otherwise fatal situations even by the standards of superhuman creatures, making him nearly indestructible. He is impervious to bullets and can take a lot of major punishment in battle before he starts to wear down. The most prominent testament to his own durability, however, was in Sonic Adventure 2 when Shadow survived his fall down to Earth from space and re-entry in the atmosphere before Eggman's robots rescued him. Despite surviving this, the experience left him with enough physical trauma to give him amnesia. Even after receiving major damage, Shadow displays a remarkably fast recovery rate, allowing him to quickly get back up in a matter of moments.

Due to being the successful culmination of Project Shadow, Shadow is immortal, does not physically age, and is presumably immune to disease. Furthermore, due to being partly Black Arms, Shadow has a connection to the Black Arms' hive-mind, allowing him to sense his kinds' presence and is immune to the Black Arms' nerve gas.

Shadow possesses tremendous willpower and unbreakable determination and, as a result, has absolute refusal to give up in any of his missions and never surrenders; he will see his goals to the end. His willpower allows him to keep on fighting when utterly exhausted, after taking an excessive amount of damage, or when he is severely outnumbered and outgunned. His will even lets him psychologically resist mind control powers. For example, Shadow was able to regain control from Black Doom despite him being part Black Arms and therefore susceptible to Black Doom's influence.

Chaos Powers
Shadow is naturally able to tap into the arcane powers of any nearby Chaos Emeralds to utilize their chaos energy to empower himself and can use a wide variety of Chaos Powers as well. Shadow can harness both positive and negative chaos energy, depending on his state of mind. His Chaos Powers are so potent that should he remove his restraints, he becomes a walking dynamo of raw power, releasing such tremendous amounts of innate energy that it forms an impenetrable barrier around him. While in this state, Shadow gains increased strength and speed, enough to overpower hundreds of Mephiles the Dark clones at once. However, using his full power tires him out more quickly.

Shadow's trademark Chaos Power is Chaos Control, and is possibly the most adept user of it in the series, having mastered it to perfection. With Chaos Control, he can manipulate space and time to slow down time and warp across space, and can use it delicately enough to distort space in small centralized areas, such as around his fists or in midair. Additionally, he can mold Chaos Control into a variety of offensive and defensive moves and can even use it to heal himself. It is unknown what Shadow's full limit for warping time and space with Chaos Control is, but it has been shown that he can warp objects and people with him all the way into space.

As described in Shadow the Hedgehog, all of Shadow's Chaos Powers increase in power with the number of Chaos Emeralds he possesses. Furthermore, he can draw power from the Emeralds without making physical contact.

Combat Skills
In combat, Shadow is a lethal and extremely powerful force that very few can defeat. He never holds back his immense strength, making him a brutal fighter with a distinct killer instinct. Shadow's skills are more than a match for even the strongest in the series and has been able to take down some of the most fearsome foes of the series on his own, such as Black Doom. To best put his skills in perspective, as seen in some of the scenarios in Shadow the Hedgehog, Shadow is one of the very few individuals who has been able to defeat Sonic in combat, even when Sonic had the Diablon for support.

Fighting Style
Shadow's fighting style focuses on direct, brutal, unrestrained and powerful hand-to-hand combat. In line with his nature and potent abilities, Shadow has adopted a fighting style where he fights his opponents using powerful blows, such as karate chops, swift punches and roundhouse kicks, to which of his attacks have a significant amount of force behind them. With the speeds Shadow can move at, he can disable the opponent through the force of his blows alone, while leaving them at the mercy at his incoming attacks.

Shadow's fighting style revolves around making heavy use of his Chaos Powers, especially Chaos Control and Chaos Spear. Using Chaos Control, Shadow can teleport up in front or behind his opponents in battle to launch surprise attacks. Also, Shadow can use Chaos Control to increase the damage he deals to his opponent when striking them, often resulting in significant forces being released and blowing the opponent a certain distance away. To give himself the advantage over his opponents, Shadow will use powerful Chaos attacks involving Chaos Energy, such as energy bolts or even intense explosions.

Techniques and Moves
Like Sonic, Shadow's basic combat moves revolves around the various forms of the Spin Attack, which is a variation on the tendency for hedgehogs to roll into tight balls for protection, and he shares many of them with Sonic. The Homing Attack allows Shadow to jump and home in on an enemy to get over large gaps he cannot normally reach, the Spin Jump lets him curl into a ball attack opponent by landing on them, and the Spin Dash lets him shoot himself forward as an acceleration roll at high speeds to break barriers or mow down enemies, the Light Speed Dash and Light Speed Attack allows Shadow to achieve light speed movements by dashing through Rings and/or enemies. He is also able perform Sonic's Sonic Boost, a move where he turn himself into a highly destructive projectile by moving and running at high speed.

Another technique, Shadow has is the Black Tornado witch is exactly the same as Sonic's Blue Tornado in witch Shadow jumps into the air, and creates a black whirlwind by circling a particular spot at high speeds which can throw his opponents into the air or blow away armor and weapons. For more direct combat, Shadow can use his Chaos Attack to deal a barrage of Chaos Energy-fueled strikes to his opponents, and his Spin Kick lets him create a small tornado that can suck enemies in and damage them.

Many of Shadow's signature techniques are Chaos Powers. Shadow's trademark move is Chaos Control, which allows him to manipulate time and space to either warp across space or slow down time, and distort space to form other types of Chaos Powers. His second most used Chaos Power is his Chaos Spear technique, where he throws bolts of Chaos Energy at his opponent. His most powerful and potent technique, however, is the Chaos Blast, which is literally a shockwave of Chaos Energy that eliminates anything and everything in a circular radius range. Shadow can, however, only use this attack when he is immersed in Chaos Energy.

Another special Chaos Power Shadow uses is his Chaos Boost technique. When using the Chaos Boost, Shadow covers himself in Chaos Energy. While in his Chaos Boost form, Shadow gains more destructive power and is immune to some enemy attacks. It also enables Shadow to utilize more Chaos Powers, such as Chaos Blast, Chaos Snap, and Chaos Lance.

Super Shadow

 * Main article: Super Shadow

Shadow is able to use and harnessing the power of the seven Chaos Emeralds' power to transform into his super form, Super Shadow. In this super form state, all of Shadow's abilities far surpass his normal ones and his Chaos Powers are increased to their full limit. Additionally, Shadow possesses theoretically infinite speed and strength, along with flight and virtual invulnerability. All of his chaos abilities are also increased to an incalculable level; he once uses Chaos Control to stop the Planet Egg's explosion, which according to Eggman, would have destroyed the entire universe. Initially, Shadow found it difficult to stay in this state due to inexperience, but he has since mastered it.

Hero Shadow

 * Main article: Hero Shadow

In Shadow the Hedgehog, Shadow is able to transform into Hero Shadow with the use of positive chaos energy, whenever his mind is fueled by thoughts of justice. In this state, Shadow is temporarily invincible and can perform a large scale use of Chaos Control. However, it only lasts for a short time.

Dark Shadow

 * Main article: Dark Shadow

In Shadow the Hedgehog, Shadow is able to transform into Dark Shadow with the use of negative chaos energy, whenever his mind is fueled by thoughts of evil. In this state, Shadow is temporarily invincible and can perform a large scale use of Chaos Blast. Like Hero Shadow, this form lasts for a short time.

Chaos Boost

 * Main article: Chaos Boost

In Sonic the Hedgehog (2006), Shadow can gain access an enhanced-up state dubbed the Chaos Boost. In this state, his powers are boosted significantly, granting him warp-like speeds, near invulnerability, and bolstered Chaos Powers.

Color Powers

 * Main article: Color Powers

By harnessing different variants of Hyper-go-on from Wisps, Shadow 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, Shadow 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

 * Inhibitor Rings: They were created to restrain Shadow's true potential, but Shadow can release them at any time. The downside is that Shadow's energy drains even faster when he's not wearing them.
 * Flame Ring: A red ring that grants a flame aura to Shadow’s somersault attack.
 * Shadow Rifle: A long-range firearm with really high firepower. Most enemies die from one shot of this weapon.

Early life
Fifty years before the events of Sonic Adventure 2, a top-secret project known as "Project Shadow" had begun on the Space Colony ARK. Led by Professor Gerald Robotnik, it was a government-sanctioned initiative to create "The Ultimate Lifeform," an immortal being that could be used for the benefit of the nation, likely in a militaristic fashion. While Gerald had initial misgivings to the purpose of the research he was assigned to, he realized that his results might be able to save his granddaughter, Maria. Suffering from the incurable disease Neuro-Immune Deficiency Syndrome, Maria only had a short time left to live, and Gerald was willing to do whatever it took to save her life. Going against his worries of stepping into territory man had no business playing with, the professor immediately began work, hoping that he could apply any newly-gained knowledge to find a cure to N.I.D.S.

Even with all the resources at his disposal, the professor was unable to make any significant progress. Without alerting anyone, Gerald decided to plead to the stars for help, contacting the Black Arms race, an alien civilization that lived upon the Black Comet, a celestial object that passed near the planet every fifty years. Its leader, Black Doom, offered to assist Gerald in his quest. He offered his blood - which ended up being the key to perfect the ultimate lifeform - in exchange for the seven Chaos Emeralds, which he would collect the next time he passed through. Knowing that the Black Arms' intentions were less than desirable, Gerald made the deal regardless, albeit with preparations to defeat the Black Arms with the cannon built into the ARK, and was able to successfully create Shadow the Hedgehog.

Once brought to life, Shadow have immediately befriended Maria, and they became really close during their short time together. Gerald, meanwhile, made emergency precautions for the return of the Black Arms, ensuring that the Eclipse Cannon - an extremely powerful laser built into the ARK - was compatible with the seven Chaos Emeralds, so that when they did return with the Black Comet, humanity would be able to defend itself instead of bowing to their whims.

However, Gerald's progress was ruined when it was leaked to G.U.N. how he was able to create the successful prototype. During the meeting between Gerald and the Black Arms, one of the other children aboard the ARK had accidentally seen what transpired and reported back to those in charge. As ties between the ARK and the United Federation had already been strained, hearing the news of the dealings with an alien race scared those in charge. Afraid of the implications, it was decided to launch an invasion and put a stop to the work being done there.

What happened next was nothing short of madness, as G.U.N. troops descended onto the ARK, causing chaos and confusion wherever they went. Immediately they went after the Biolizard, which they thought was the successful "Project Shadow" prototype, and in the process of putting the creature into stasis, lost quite a few soldiers. From there they went about doing damage control, shutting down everything, getting everyone off the ARK, and killing those who resisted if need be. Knowing that the G.U.N. forces would be there at any moment, Maria convinced Shadow to enter an escape pod, her final wish to him that he give the people on the planet a chance to be happy. Wishing him goodbye, Shadow could do nothing as he watched the G.U.N. soldiers storm into the lab, firing a shot which would forever change the hedgehog's life as it ended the life of Maria Robotnik.

Learning of his granddaughter's death, Professor Gerald soon went mad with grief, swearing vengeance on humanity for taking away the only thing that ever meant anything to him. Though just what exactly transpired is cloudy, what is known is that both Gerald and the escape pod that held Shadow were gathered by G.U.N., Shadow having to be put to sleep in a stasis capsule within Prison Island, and Gerald being incarcerated and charged with the crimes that happened aboard the ARK.

Theme songs
The video games have featured several theme songs for the character. Shadow's themes consisted primarily of the techno and industrial genres often with synched vocals that are barely audible in Sonic Adventure 2 and Sonic Heroes, but have shown an increasing preference towards the hard rock genre in more recent games.


 * Sonic Adventure 2: "Throw It All Away" - Everett Bradley.
 * Sonic Heroes: This Machine - Julien-K. (This was a team theme shared with Rouge and Omega.)
 * Shadow the Hedgehog featured multiple themes:
 * "I Am... All of Me" - Crush 40
 * "Almost Dead" - Powerman 5000
 * "Waking Up" - Julien-K
 * "Chosen One" - A2
 * "All Hail Shadow" - Magna-Fi
 * "Never Turn Back" - Crush 40
 * Sonic the Hedgehog (2006): "All Hail Shadow (Remix)" - Crush 40
 * In addition, there are several vocal level themes associated with Shadow's character in Sonic Adventure 2:
 * White Jungle: "Rhythm And Balance" - Everett Bradley.
 * Final Chase: "The SuperNatural" - Everett Bradley.
 * A special remix of "Tripod Baby" performed by M-Flo was released as a promotional song for Shadow.
 * In Team Sonic Racing, Shadow's theme is "Team Ultimate: Shadow", which is a shortened up rendition of the Sonic the Hedgehog (2006) version of "All Hail Shadow" that plays during his Team Ultimate.

Notes & Trivia

 * Though the design of Shadow was meant to be a secret until such time Sega decided to reveal the finalized version, details of the character were leaked when ReSaurus announced they were making figures of Shadow and Rouge, much as they had for the first Sonic Adventure title. However, the company went out of business before they could release these figures to the masses.
 * According to the games' canon (and confirmed by Takashi Iizuka), Shadow and everyone else requires at least one Chaos Emerald close by to draw power from for Chaos Control, or the technique is impossible - however, Shadow has definitely appeared to use Chaos Control and other Chaos Powers during gameplay of some games without visible Emeralds nearby. Fans have stately argued that it is implied in statements which Shadow made in Sonic Battle that his memory of Maria allows it.
 * Shadow and Knuckles were originally confirmed to appear in Sonic Unleashed. Although Shadow doesn't appear, he is briefly mentioned; during an interview with Brenda, she will ask the name of the creature that came from the planet's core. Sonic can incorrectly answer 'Shadow the Hedgehog.'
 * In the Japanese commercial for Shadow the Hedgehog, Shadow is seen dancing.
 * In his artwork for Mario & Sonic at the Olympic Games, Shadow is missing his tail.
 * Shadow uses his left hand when using weapons in Shadow the Hedgehog. His counterpart, Lancelot, however, fights with his right hand, possibly because of the Wii motion control. In Sonic the Hedgehog Shadow always leads with his right for his attacks during cutscenes. Shadow may either be ambidextrous or have left eye dominance, seeing as those with left eye dominance are recommended to fire guns whilst favoring their left hand. He also tends to cross his right arm under his left arm in most artworks.
 * The Official Game Guide for Sonic Generations mentioned that a scientist is the one who ejected Shadow's capsule to the earth, however, he was ejected by Maria Robotnik.
 * In the 2011 Guinness World Records Gamer's Edition, Shadow placed 25th in the "Top 50 Video Game Characters of All Time" while Sonic placed tenth.
 * Shadow was not originally intended to be in Sonic Heroes, revealed in an initial list of teams for the game. Rouge would have been in a team with Cream and Amy and there was no mention of Omega.
 * In Sonic Heroes, Shadow is shown to be faster than Sonic in grinding, but this has been modified in Sonic the Hedgehog.
 * Shadow's trophy pose in Super Smash Bros. Browl is almost identical to his artwork for Sonic the Hedgehog (2006).
 * Shadow's skin color is usually tanner in his 2D artwork than in his 3D artwork.
 * Normally Shadow is seen with red eyes, but in his Sonic Chronicles artwork and pictures his eyes are more of an orange color, but this may be because the artwork in Sonic Chronicles: The Dark Brotherhood was made by someone other than the usual Sonic Team artist.
 * In the game Sonic Chronicles: The Dark Brotherhood, Shadow is missing a quill on his head. This is also present in Sonic X.
 * In Sonic Generations, the player may be rewarded with the fourth Chaos Emerald for defeating Shadow (third if he is fought before Perfect Chaos). Coincidentally, in his own game, Shadow mentions the fourth Chaos Emerald in a line, "Where's that damn fourth Chaos Emerald!?", which has since gained Internet popularity.
 * Shadow's three main Chaos abilities are generally color-coded in relation to the three Chao alignments. Chaos Control requires positive chaos energy that generally glows blue, as Hero Chao have blue markings. Chaos Spear is generally depicted as being yellow-white, while Neutral Chao have yellow markings. Chaos Blast requires negative chaos energy, and is generally red, whereas Dark Chao have red markings.
 * In Sonic & Sega All-Stars Racing, Shadow's profile says he likes "nothing."
 * In the 2D indie fighting game Skullgirls Encore, the 17th selectable color palette of the character Fukua is a direct reference to Shadow the Hedgehog.
 * Shadow's trophy pose in Super Smash Bros. for Nintendo 3DS and Wii U resembles his artwork for Sonic Rivals.
 * Strangely, in the previous leaked transcript of Sonic the Hedgehog (2006), Shadow was described as a "fifteen-year-old" hedgehog, just like Sonic, unlike all the other official materials which do not put an actual age to him.
 * Despite many fans having speculated that Silver is related to Shadow due to Sir Lancelot and Sir Galahad's relationship in Arthurian lore (where the latter is the son of the former), Takashi Iizuka has confirmed that Silver is not a descendant of Shadow.
 * Shadow is described by GUN affiliate Frances as having an IQ of about 200.
