Shadow the Hedgehog (シャドウ・ザ・ヘッジホッグ) is a fictional character from the Sonic the Hedgehog series.
Shadow (Modern)
He is an 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) 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 cures for incurable deadly illnesses, more specifically for Gerald's granddaughter Maria Robotnik, but he was captured and put into stasis by the military when he was deemed as a threat to humanity. Fifty years later, Shadow was released by Dr. Eggman to help him conquer the world. 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.


Sonic Adventure 2

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 the resources at his disposal, Professor Gerald was unable to make significant progress. Without alerting anyone, Gerald decided to plea 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 immediately befriended Maria, and they became close during their short time together. Gerald, meanwhile, made precautions for the return of the alien race, 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 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.

Learning of his granddaughter's death, Professor Gerald soon went mad, 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.

Sonic Boom (TV Series)

Shadow silently watched Dr. Eggman and Metal Sonic from a distance at Lyric's Tomb, which Team Sonic had gotten themselves locked within, before leaving. He soon after confronted Sonic and Tails at the Abandoned Research Facility where both of them had opened a portal to travel to the past which Shadow refused to let them go through. Taunting Sonic for being weak due to his loyalty to his friends, Shadow engaged them in a fight across time. On the verge of defeat, Shadow was kicked into a portal by Sonic that sent him to the near future, after Team Sonic had defeated Lyric the Last Ancient. Although prepared to fight again, Shadow instead gave the team him approval when he saw the beaten Lyric before walking away, chuckling.

Upon finding Lyric excavating an area, Shadow confronted the villain, but did not object to Lyric's dark sense of justice when he sought to seize the Lost Crystal of Power. Grimly, Shadow declined as Lyric took an interest in making him his slave, only for Lyric to plant a Mind Control Device on him.

While under Lyric's control, Shadow confronted Team Sonic, but was beaten by Sonic in a race who knocked him unconscious. When he awoke, Shadow had been freed from Lyric's device. As Shadow had Tails analyzed his former Mind Control Device, a hologram of Lyric appeared to warn the group not to cross him. Shadow threatened Lyric to come and face him, but the villain declined, so Shadow left on his own to hunt down Lyric and get his payback.

Shadow finally found Lyric when he was about to destroy Team Sonic with a cannon, whom Shadow saved by disabling Lyric's weapon. He then kicked Lyric away as Sonic opened a trapdoor, sending Lyric falling to his defeat. While everyone agreed their teamwork made the difference, Shadow called them out for being pathetic and left on the notice that he was Sonic's superior.


Sonic X (Anime)

Shadow is extremely arrogant, aggressive, brooding and very loyal to whomever he is serving and determined to whatever cause he is fighting for. He is anti-social and does not speak or smile much. However, he often smirks when being sure of himself, or if he thinks lowly of someone. But deep down, he does have a heart. He cares for those who cared for him such as Maria, Molly and Chris Thorndyke and often follows their goals in his own fashion no matter what the cost is. He can be caring to Sonic by showing up and saving Sonic when he needs it the most and genuinely respects him as a rival. Because of his past though, Shadow does not trust anyone besides himself.

Shadow is easily the most self-sufficient of all the characters. However, his lonesome and arrogant attitude also puts him apart from the other characters. Nevertheless, Shadow can at times be uncaring. For example, when he learned of Cosmo's true mission, he set off to kill her. Shadow, however, did this to try to protect the universe, implying that while he has a good motive, the means used to achieve it are only acceptable to him.

Shadow firmly believes that he is the "Ultimate Life Form" and almost all other life forms are lesser beings and thinks that no one can stand a chance against him. Despite this, he respects a worthy opponent and likes to see someone give him a challenge, apart of why he respects his arch-rival, Sonic.

Shadow only talks when it is absolutely necessary and dislikes being in groups, preferring solitude. Shadow often thinks teamwork is unnecessary because he can handle everything on his own. However, he will work with others if ordered to, or if they've got a goal in common.

Shadow is often depressed about the loss of Maria which is why he keeps to himself, but his relationship with Maria is obvious as he goes to great lengths to protect the planet and keep her dream of peace and prosperity alive. He has also been seen protecting other characters, for example Sonic, Chris, Molly, and Rouge, proving that while his attitude makes him seem like a careless person, he does have some compassion.

Sonic Boom (TV Series)

Shadow is a cold and edgy character. He comes off as blunt, arrogant and uncaring and does not take kindly to outside interference, swiftly disposing of whoever gets in his way. Extremely aggressive and lacking in inhibitions, he is perfectly willing to eliminate a foe rather than merely subduing them, unlike Sonic, and believes that justice must be had by any means necessary. Despite his villainous tendencies, his motivations to fight are purely related to his pride. Because of this, he is often very destructive and even brutal in battle. Still, he usually maintains a calm, if not aloof and indifferent, attitude, and shows a general interest in nothing. Shadow has a strong sense of purpose and sticks to his goals with grim determination and intense focus, not resting until it is fulfilled. He is also not one to run away from a confrontation.

Shadow is fiercely independent. A lone wolf, he believes friendship to be a sign of weakness and refuses to serve anyone but himself. Even when joining forces with others, he has no interest in collaborating or the group's plans unless it aligns with his own goals. He is likewise very serious and has little patience for silly behavior, having no issues criticizing others harshly or speaking out his low opinions for others. He despises weakness and people he deems weak, but is willing to at least give compliments when deserved. Shadow is also vengeful and not one to let go of grudges easily; once free from Lyric's control, he spent most of his time hunting down Lyric to make him pay for enslaving him.


Sonic X (Anime)

Shadow had black red fur. He has black red eyes and wears white red gloves. His nose is black. He also has orange at the bottom of his face, and wears white red sneakers.

His attire includes white gloves with red backs which have long red and black cuffs with fasteners. His shoes look much like the Air Shoes, except his has large red tongues and longer red and black cuffs. Around his wrists and ankles he has golden ring bands.

Sonic X

Sonic is Shadow's arch rival. When they first met, Shadow showed interest in meeting Sonic, noting their similarities and mocked him as a weak opponent as he was able to defeat Sonic in combat. However, he later changed this view about Sonic after seeing Sonic using a Chaos Control. Shadow got impressed by Sonic and had come to respect him as a rival, ever since. After remembering Maria's true wish, Shadow helped Sonic and his friends and fought with Super Sonic to stop the Space Colony Ark from destroying the earth.

When he appeared in the Metarex Saga, Shadow did not know Sonic and his friends because of his amnesia. Because of this, he fought against Sonic and his friends with Eggman. After Molly's death, Shadow realized that Sonic were right about Eggman's evil plans and therefore left Eggman to defeat the Metarex himself. After knowing about Cosmo's secret about being a spy for the Metarex, Shadow defeated him only to to kill Cosmo to prevent her from sending information to the Metarex. In the battle with Final Mova, Shadow showed some respect to Sonic and they worked together to defeat Final Mova and he charged himself with Sonic in Sonic Power Cannon despite the damage that the power could do to him only to help Sonic to defeat the Metarex once and for all. He also knocked out Sonic to prevent him from risking his life to save the galaxy. Overall, there is always tension between Shadow and Sonic, but they have as well some respect for each other and Shadow will puts his differences with Sonic aside to help Sonic against any powerful enemy that come in their way.

Sonic Boom

Sonic is Shadow's tense arch rival and his equal in both speed, abilities and dashing looks. Despite their similarities, they are polar opposites in every way, with Shadow disagreeing with nearly everything Sonic stands for. While Sonic is joyful, free-spirited and adventurous, Shadow is brooding, serious and violently aggressive. Whereas Sonic draws strength from his friends and believes in teamwork, Shadow is a loner who only relies on himself.

Shadow shares a bitter arch-rivalry with Sonic which goes way back, and is determined to defeat him at all costs due to his pride. He finds Sonic extensively annoying and criticizes him for being weak and a disgrace to hedgehog-kind. Shadow also firmly thinks of himself as Sonic's superior, and whenever they meet, they usually end up arguing. While willing to ignore Sonic out of a sense of superiority, Shadow will just as easily pick a fight with him and go out of his way to defeat or even kill Sonic to prove how pathetic he is, which Shadow justifies on the grounds that Sonic deserves it for being such a disgrace. In fact, fighting Sonic is one of the few things Shadow ever shows an interest in. For all his animosity though, Shadow has a small degree of respect for Sonic, willingly complimenting Sonic and letting him go after he beat Lyric.
