Shadow the Hedgehog is a mobian hedgehog and the end result of Project: Shadow, an effort to create the Ultimate Lifeform. Created by Professor Gerald Robotnik in his efforts to find a cure to a rare disease known as NIDS that was affecting his granddaughter Maria, Shadow was gifted with the powers of the alien Black Doom through that entity's blood.

After the project was forcibly shut down by the government, Shadow was put into stasis for fifty years and then awakened by Dr. Eggman, Gerald's grandson, to help him take over the world. Shadow sought instead to destroy the world to avenge Maria, who had been killed during the raid onboard the Space Colony ARK, where they both had lived. However, after realizing he had been led astray by false memories, Shadow would join forces with Sonic the Hedgehog and his allies to save the world, afterwards becoming a hero who helped to save the planet on multiple more occasions.

Early Life

Shadow was created by Professor Gerald Robotnik fifty years ago aboard the Space Colony ARK, with the help of the Black Arms leader, Black Doom, who contributed his own blood to the "Ultimate Lifeform". However, the two creators envisioned two contrasting purposes for their creation: Gerald wanted Shadow to one day protect the world, whereas Black Doom was intent on having Shadow as his chief agent in conquering the world. Regardless, Shadow swore to Maria Robotnik, the professor's granddaughter of whom he was very close, to protect the planet she loved. Shadow's stay aboard the ARK ended when G.U.N. Soldiers raiding the space station, apprehending the professor and killing Maria, the death of whom Shadow witnessed moments before being ejected from the ARK. He was soon recovered and put into stasis somewhere on Prison Island.

Fifty years later, Shadow was awakened by his creator's grandson, Dr. Eggman, who had recently stumbled upon the professors diary. Filled with anger at the death of his close friend, Shadow sought revenge on the people of the world. Aided by the Doctor, who agreed to collaborate with the ultimate life form to achieve his own plan to take over the world, Shadow and his new master gathered Chaos Emeralds to be used for the powerful Eclipse Cannon. During his quest, he ran afoul of Sonic the Hedgehog, who had been blamed for Shadow's crime of stealing an Emerald from the bank. After a number of battles, Shadow saw his vengeance approaching fulfillment, but was moved to help save the planet he sought to destroy. Thought lost after he became Super Shadow and joined Super Sonic in battling the Finalhazard, Shadow was later found by his old ally Rouge the Bat in one of Eggman's bases. Awakened with no memory of his past, the black Hedgehog joined Rouge and unlikely new ally E-123 Omega to form Team Dark. This group fought alongside-and against-Team Sonic, Team Rose and Team Chaotix to battle the evil Metal Overlord, a monstrous form taken by Metal Sonic.

Soon, Shadow found himself dealing with the Black Arms invasion of the planet. As the Black Arms descended from the sky to invade, Black Doom appeared before Shadow and told him to bring him the Chaos Emeralds "as promised" before disappearing. Fueled with desire to seek out his past and find the truth behind Black Doom's words, Shadow sped off to obtain the emeralds. During his adventure, he provided some level of assistance to the invaders, which resulted in feelings of mistrust towards him from some citizens of the planet. After successfully gathering all of the emeralds, Shadow was confronted by Black Doom, who commanded him to give up the emeralds so that they can begin the 'Ritual Of Prosperity'. Sonic and the others, including Dr. Eggman, then arrived and told Shadow not to listen to the alien leader. After it was revealed that Black Doom wished to harvest humans as an energy source, he took the Chaos Emeralds from Shadow and used Chaos Control to warp the Black Comet down to the surface of the planet. Black Doom then explained that he helped Professor Gerald create Shadow but only in return for the Chaos Emeralds, which were needed to bring the comet down to the surface. This revealed that Shadow was actually created using Black Doom's DNA. As Eggman was in disbelief that his grandfather would betray the planet, Black Doom paralyzed everyone with a special gas and left them to be devoured by his alien offspring. As the end seemed near, Shadow suddenly heard Maria asking for help and he broke through the paralysis.

Black Doom fled, leaving behind Shadow, the only hope for the planet. Shadow caught up with Black Doom, only to suddenly be attacked by the alien's mind control. Black Doom told him that he could control him as they had the same blood running through their veins, but Shadow refused to believe it. Just then, the Chaotix activated a film showing a sane Professor Gerald Robotnik. In the video he referred to Shadow as his "son" and told him that he was the only hope for the planet. It was revealed that the only way to defeat the Black Arms was to destroy the Black Comet using the Eclipse Cannon, a powerful weapon built into the ARK. As the video ended, Maria stepped into the frame and gave Shadow the inspiration he needed to break through Black Doom's control. Black Doom escaped and prompted Shadow to use the Chaos Emeralds to become Super Shadow and fight the alien leader. Black Doom, now in his Devil Doom form, fought Shadow but was defeated. Shadow then used a super-powered Chaos Control to warp the Black Comet back into the planet's orbit and tear it apart with a blast from the Eclipse Cannon. Everyone cheered in joy as the alien threat was destroyed seemingly forever. On board the ARK, Shadow looked at a picture of Maria and Gerald before tossing it away, remarking "Goodbye forever... Shadow the Hedgehog".

In the events of a timeline that was later aborted, Shadow and the other members of Team Dark became involved in a series of time-traveling battles with a villain known as Mephiles. After possessing Shadow's shadow in order to take on a form resembling the Ultimate Lifeform, Mephiles led them on a chase that ended with a horrible revelation. In the future resulting from that timeline, Shadow had been blamed for the catastrophe that had befallen the planet, and hunted down by his own reprogrammed comrade Omega and imprisoned. However, Rouge vowed to stand by Shadow no matter what, and after working with Silver the Hedgehog and Sonic to defeat Mephiles' ultimate form of Solaris, these events were erased from history. Shadow and Rouge later took part in an Extreme Gear competition with a disguised Metal Sonic, and also became involved in Eggman's efforts to abuse the power of the Wisps. He and Sonic's other friends and allies were later captured by the Time Eater, and Shadow faced off with Sonic prior to the blue Hedgehog's defeat of their foe.


Very much convinced of the belief that he is the Ultimate Lifeform, Shadow has been described by Rouge as an "arrogant so-and-so," and upon making a decision is slow to change his mind or let anyone stand in the way. Beneath his gruff exterior, however, lies a heart with a genuine desire to protect the world, though at times he seems convinced that his is the only voice that matters in accomplishing this task, which can make for stubborn behavior and poor decisions. Very sure of his powers and abilities, he has the tendency to go off on his own or challenge forces he hasn't yet become acquainted with, and this often gets him into trouble. However, he is not above receiving correction, particularly from his closest friends, when the situation calls for it.

Shadow was previously consumed with his past, specifically during a period of his life in which he had amnesia, and recognizes his kinship with the alien Black Arms. However, Shadow is also wise enough to recognize the Black Arms as a race of predators and monsters, and is determined to see them wiped out. While slow to smile or exude warmth, Shadow does care for his friends and allies, even with the knowledge that his longevity may allow him to outlive them all. Most often, however, he puts on an attitude of cool indifference or businesslike precision, very rarely showing his more vulnerable side.

Powers and Abilities

In combat, Shadow is a formidable foe. He is capable of fighting fighting hordes of enemies single handed and matched only Marsha in combat ability. Thanks to the natural speed bestowed unto him and his footwear, Shadow is capable of matching Sonic's natural speed, dodging bullets, run along the surface of water and activate devices at high speed. He can as well match many of Sonic's other abilities, including the Spin Dash.

Shadow possesses higher strength than most of his species, and is incredibly resilient, capable of taking a great deal of punishment but staying in a fight. As the Ultimate Lifeform, Shadow is also thought to be ageless and immune to disease.

Shadow possesses an inherent connection to Chaos energy lacked by many of his allies, and can utilize Chaos Powers without the use of a Chaos Emerald or the Master Emerald, though using either heightens his abilities. Shadow possesses absolute mastery over his Chaos energies, enough to channel it through his fist to increase the force of his punches. His Chaos powers include the Chaos Spear which lets him shoot or grab arrow-shaped energy spears, Chaos Control which allows him to warp across space and slow down time, and Chaos Blast where he either creates an intense explosion or land punches with explosive power.


Shadow wears a pair of specialized shoes called rocket-skates. These footwear are the primary source of Shadow's speed, producing small jet streams that lets him hover-skate at speeds nearing Sonic's. Alternatively, Shadow can use his Rocket-skates to produce fire to attack opponents with, assist his jumps or achieve midair hovering.

Shadow wears two Inhibitor Rings on his wrists that limit the amount of power he uses during combat and other situations. By removing them, Shadow is able to use his full power, turning him into a nigh-unstoppable force.


Chaos Shadow

If he removes his Inhibitor Rings, Shadow can transform into Chaos Shadow. In this form, Shadow becomes a dynamo of raw power with all of his abilities greatly enhanced and energy pouring out of him.

Super Shadow

By harnessing all the power of the Chaos Emeralds, Shadow can transform into Super Shadow. In this form, Shadow is capable of flight, invulnerability, and nearly limitless Chaos power.


Gerald Robotnik

Shadow was created by the renowned scientist Gerald Robotnik, using Black Doom's DNA. Gerald had made many attempts to create the Ultimate Lifeform before Black Doom and his children, the Black Arms, came to Earth. Unfortunately, the closest he came was the Biolizard. Black Doom, however, approached Gerald and offered his help, but only on one condition; if Black Doom helped Gerald, the professor must promise to deliver the seven Chaos Emeralds to him. Gerald agreed to these terms, and Black Doom gave some of his DNA, which was added to the samples that Gerald had already obtained. The result of this experiment was Shadow the Hedgehog. Gerald seems to be one of few people whom Shadow felt happy around, and the professor might have acted as a surrogate father to him. This is further proved when Gerald refers to the hedgehog as his "son", having given Shadow genuine emotions to prevent him from becoming a weapon as the government intended. Despite this, however, when defeating the Finalhazard, Shadow states that he promises to "destroy all evil that the professor had created," implying that while he might still respect Gerald Robotnik, he nonetheless feels that any bad things that Gerald Robotnik had done after going insane must be stopped.

I order to put the past behind him, he proceeded to fulfill Gerald's true wish of protecting the planet by destroying the Black Arms.

Maria Robotnik

Prrofessor Gerald's granddaughter, Maria Robotnik, is by far the one person that made Shadow the happiest. She was like a sister to him, and they shared the same dream; to visit Earth. Unfortunately, G.U.N. deemed Project Shadow to be too big a threat to the world. As a result, they eliminated everything they could in relation to the project, including the people. Maria was shot and killed by G.U.N. during the raid on the ARK. Her last parting words were "Sayonara, Shadow the Hedgehog," Shadow still stays strong to keep his promise to her and mourned her death.

Dr. Eggman

Shadow's approach to Eggman is different from most characters in the Sonic series. Shadow sees Eggman as the super-genius he has proven to be, rather than the megalomaniac that Sonic and the others see him as. This can be backed up by the fact that Shadow almost always calls Eggman by his title "the Doctor", as opposed to his alias of "Eggman." Eggman has shown similar respect by referring to Shadow's powers as "spectacular", and by how he sometimes applauds Shadow.

Even though Shadow and Eggman display a level of respect toward each other, they also show a dislike toward one another. Even though Shadow and Eggman have some respect for each other, they still do not regard each other as anything more than an acquaintance.

Sonic the Hedgehog

Shadow's arch-rival is none other than Sonic the Hedgehog. They became enemies but later became bitter arch-rivals. Since meeting each other, there has been a never-ending competition between the two, and their battles can range from friendly races to fierce death battles. In any case, one always wants to outdo the other.

Shadow and Sonic frequently fight due to their own views on justice and morality and how to act on them. Their constant disagreements quickly turn into outright death matches. Each does not care what the other thinks of their views. In a sense, the two hedgehogs are polar opposites in every way except their appearance. Almost every time they meet, they fight ferociously. Neither is ever willing to accept defeat. Their rivalry has developed over time and is now more friendly, yet still fiercely intense as Shadow thinks that Sonic is his rival in all aspects of his life.

Despite their fierce arch-rivalry, Shadow and Sonic have helped each other on occasion.  Overall, while the two still get on each other's nerves because of their conflicting views, there is also a mutual respect between them. They are both willing to put their differences aside and help each other when needed. Overtime, Shadow has become more confident about Sonic doing what is right, and Sonic has become more acceptant of Shadow's violent attitude as well.

Rouge the Bat

Shadow has a companionship with Rouge the Bat that is based mainly on partnership. They often work together during mission, but they do not spend time in the other's presence outside of duty alliance. This marks them as occasional teammates when it comes down to appreciation, respect, and consideration over the term of "best friends." Shadow has not shared the closeness of opening up to neither Omega or Rouge the way best friends would do, let alone accompanying them as casual company due to his independent and distant nature, unlike how Sonic interacts with his companions. Nonetheless, the fact that Rouge is one of the closest people for Shadow to interact with (excluding Gerald and Maria, who are dead) is certain.

E-123 Omega

Shadow has a very close relationship with Omega who, other than Maria and Rouge, may be Shadow's closest friend. The bond between the two may have been strengthened by the fact that Shadow is the Ultimate Lifeform and that Omega is considered the Ultimate Robot and share a common importance to the world.

Black Doom

The relationship between Shadow and Black Doom may have been brief, but has played a significant role in Shadow's life. Shadow was made from Black Doom's blood, in a deal between the alien and Professor Gerald; this technically makes Black Doom Shadow's biological father. Black Doom, at first, tried to get Shadow on his side by playing on what remained of Shadow's painful memories of losing Maria.

Black Doom threatens Shadow and demands extreme loyalty and respect without compassion, even when he aids him. He also doesn't tolerate any kind of mistake or failure, no matter how difficult the task on Shadow's part may be. In the end, Shadow refused to aid him and decided to put the end to his biological father and his "offspring" after learning of his true plans.


Initially, Shadow did not hate humans and promised his best friend Maria to give them a chance to live happy lives. However, his opinion about them changed after G.U.N killed Maria and he came to loathe humanity itself for what they did to her. After his reawakening, Shadow planned to destroy humanity, thinking he had promised Maria revenge at them for her death. However, when he remembered his true promise to Maria, he cast aside his vendetta and risked his life to save humanity.

After losing his memories, Shadow did not care for humans, regarding them as pathetic and held no sympathy towards them. While Shadow still holds a general loathing of humanity, he has made it his mission to protect them due to his promise to Maria, even becoming an agent for G.U.N.


Shadow has a friendly rivalry with Marsha while Marsha sees him as her friendemy. Despite Shadow's arrogance, Marsha tries to remain friendly towards him and geniually cares about him.
