I gave you life, and THIS is how you repay me! The irony of it all... is that I gave you life... NOW, I'll take it back.

— Black Doom, Shadow the Hedgehog

Black Doom (ブラック・ドゥーム Burakku Dūmu?) is the main antagonist in Shadow the Hedgehog. He is the sinister leader of the Black Arms and the oldest member of his kind. The Black Arms are Black Doom's own spawn and appear to operate with an insect-like hive intelligence, seemingly preventing any attempts to challenge Black Doom for leadership. He presents an almost religious front and shows little respect for humanity due to its sins against each other and the planet earth.

Black Doom's philosophy is a little more than egotistical justification for his own dark deeds. Following his return to earth in the present day, he wanted to enslave the humans and use them as food for him and his army, but met his defeat at the hands of Shadow the Hedgehog.


In his general appearance, Black Doom is rather menacing and un-aging with his species having otherworldly demon-esque traits. He has a black-brown legless body with three red bestial eyes, twin wide horns with red tips, a set of spines on his scalp, three-fingered paws with claws, and no lips. For attire, he wears a dark brown worn robe with black-brown shoulder pads and golden accents, a maroon drape scarf with tattoo markings hanging from the back, golden chains with a set of silver-spiked medallions possessing a gem, and a double black cord necklace with red, blue and purple ornaments on one and golden and silver pendants on the other. His telepathic voice has an echo-effect to it and he emits an unnatural aura around himself.

The differences is that in cutscenes, his size is about half the same as his own kin but when battling face-to-face, he appears quite larger than that.



Black Doom claims that he and the Black Arms have visited earth for as far back as two thousand years. It is unknown just how much of an effect he has had on earth's history, although the bird-shaped ruins in Glyphic Canyon and Sky Troops are revealed to be flying temples transported to earth by Black Doom over two thousand years ago to be used as weapons by the Black Arms for taking over earth.

Black Doom explaining his deal with Gerald Robotnik fifty years ago.

Fifty years prior to the events of the Black Arms incident, Black Doom formed a sort of alliance with Gerald Robotnik. He and Gerald created the Ultimate Lifeform, Shadow, in order to expand Gerald's research and help Black Doom retrieve the Chaos Emeralds. Shadow was created from Black Doom's blood, giving him access to Black Doom's Chaos Control abilities. However, Gerald realized the threat his new alliance presented to earth and secretly planned to use Shadow and the newly built Eclipse Cannon to destroy the Black Comet when it made its next regular fifty year visit. However, soon after the events detailed in the Space Colony ARK incident occurred, Gerald's initial plan was forgotten as he sunk into grief and madness after his granddaughter, Maria Robotnik, died during the raid on the ARK to shut down Project Shadow by GUN.

Shadow the Hedgehog

Black Doom appeared at the beginning of the game as a hologram projected by his third eye to inform Shadow the Hedgehog as he was thinking to himself about his troubled past. Black Doom claimed that "the day of reckoning" has arrived. Just then, a massive invasion of the Black Arms began as a vortex of dark, swirling storm clouds drop Black Arms soldiers on Westopolis. Shadow figures that Black Doom will reveal his past if he follows Black Doom's orders, so he rushes into the city to seek out Black Doom. Black Doom uses Shadow throughout the game in order to retrieve the seven Chaos Emeralds for him. He commanded his army to attack six major cities around the world in search of the emeralds and in order to weaken earth's defenses. He continuously pressures Shadow to denounce the home he has made on earth and swear allegiance to the Black Arms and their goals. He often tries to accomplish this by trying to manipulate Shadow into believing that no good can come from the continued existence of humanity, offering to tell him about his past, and even goes so far as to put Shadow into a recreation of what happened to him on the Space Colony ARK 50 years ago to better justify the evil humans are capable of. Black Doom's plans included taking control of the ARK for his nefarious desires. Once the ARK was seized control of, Black Doom used the Eclipse Cannon to destroy Central City, capital of the United Federation, where the President was currently residing. He did this so that it may be used as the site for the Black Comet to take root with the planet. His other plans included strengthening his armies by reawakening the temples, which were actually flying fortresses left behind from a past age. Also, he planned on destroying the human's data networks, several military bases, their world leaders, and planting Black Arms plants around the world to slowly transform the planet into a blood-ridden wasteland.

As the player proceeds through the game, they learn more about Black Doom's motives and his connection to Shadow.

When Shadow gains all of the Chaos Emeralds, Black Doom steals them, and reveals that he needed them all to amplify his Chaos Control to full power so that he can warp the Black Comet to earth. The comet's own velocity was not fast enough to bypass the earth's atmosphere and so he needed the Emeralds to perform a massive Chaos Control so that he could root the comet to earth and use it to unleash a paralyzing nerve gas on the planet's population to make them food for his Black Arms spawn, starting with Sonic, Tails, Knuckles, Amy, Rouge and Eggman when they arrived to stop Shadow from giving the emeralds to Black Doom. Shadow's inherited genetics from Doom make him the only other creature on the planet capable of resisting the effects of the gas. Retreating to his inner sanctum at the very center of the comet, Black Doom defends himself from his advancing offspring with a perimeter of his most elite Black Arms soldiers. When Shadow reaches him, Black Doom finally reveals the truth of Shadow's parentage but is soon after interrupted by a fifty-year-old transmission of Gerald from the Space Colony ARK, accidentally activated by the Team Chaotix Detective Agency, made up of Espio, Charmy and Vector. The transmission reveals to the world Gerald's secret plan to destroy the Black Comet and gives Shadow the resolve to defeat the tyrant. Before he can attack, Black Doom teleports away and transforms into his most powerful form—Devil Doom. Shadow uses the Chaos Emeralds Doom left behind to transform into Super Shadow and give chase to Devil Doom. The two engage in a final battle for the fate of the earth, in the sky over the rooted Black Comet. Shadow is ultimately able to defeat Devil Doom, sending him tumbling down to the city below. As he has not appeared since, the rest of his fate remains completely unknown.


Black Doom is presented as a highly ruthless, sadistic, manipulative, and power-hungry tyrant. He regards humans as pathetic creatures that have led to the destruction of their own planet. Black Doom has neither affection nor sympathy for anybody or anything, including his own army and his creation, Shadow. He gladly took the lives of his own army in order to destroy Central City, the city he chose for the site of the comet when it was teleported down via Chaos Control. Black Doom has a dark lord persona in which he committed horrible atrocities throughout the story, such as attacking six cities and killing millions, blowing up Central City, and torturing the humans and having his army consume their bodies. He also does not forgive any mistakes or failure, no matter how difficult the task on Shadow's part may be.

Black Doom's plans for the planet extend much further than simply conquering earth. His main goal is to have him and his armies feed off the humans, which he states are a great energy source for them. According to Doom, once the planet is under his control, the humans will never see the sun again and the planet will cease to be blue. It seems Doom wants to conquer the planet as a step closer to the entire universe. He has no respect for humans, as he sees them as fools who have committed crimes against themselves, and believes that he is doing them a favor by using them as a food supply for his race.

While Doom claims that he has Shadow's best interest at heart, he does not care for him at all and is only interested in his power. He often tried to manipulate Shadow in order to turn him against humanity, but this caused Shadow to see Black Doom as his ultimate enemy in the end. Doom sees Shadow as his gateway to the Chaos Emeralds and his unusual skills would make him a great addition to the army. Doom often used Shadow to do tasks that would give him an advantage, such as destroying the humans' data servers so information could no longer be transferred among the humans, awakening dormant temples to be used as weapons, and even attempting to assassinate the president.

Unlike other Sonic villains such as Eggman, Black Doom is completely devoid of any sense of humor. He is quite arrogant, claiming that he not only rules the universe, but that he is the strongest being in the universe as well (to the point of saying he is immortal). Despite all this power, he is still defeated by Super Shadow, which ironically was his fault, as he left the Chaos Emeralds with Shadow when he warped away to transform to Devil Doom, believing their power was useless against him. He reconsidered this belief during the final battle, admitting that he had underestimated the Emeralds' powers.

Powers and abilities

Whilst few would challenge Black Doom, he has numerous abilities which make him a fearsome foe for those who would dare. For important long range communication, Black Doom can send his third eye forth to do various tasks that would require him while he is away. Doom's Eye can speak, and can project holograms of Black Doom, which possess many of Doom's abilities, as well.

Black Doom inducing Chaos Control.

Black Doom can levitate/float which seems to be his primary method of mobility as he appears to have no legs, even when transformed into Devil Doom. One of his main abilities is inducing Chaos Control, which he can use with just as much proficiency as Shadow. When using all seven Chaos Emeralds, he could teleport the Black Comet down to earth from space. He is capable of teleportation and is capable of transporting others as well as he demonstrated transporting Shadow to various locations on earth and even into cyberspace. He also seems to be able to phase right through solid objects. Compared to humans, Black Doom seems to have eternal youth, or at least extended longevity, as he lived for over 2000 years. His blood was used to help create Shadow, who obtained eternal life.

Black Doom creating an illusion around Shadow.

Black Doom possesses a large amount of mystical abilities. He can telepathically give someone like Shadow the illusion of going back to another time and place, and can sense energies, a person's presence, and their inner thoughts and emotions. He also possesses a mental link with Shadow due to Shadow being created from him; he failed in his attempt to use mind control on Shadow. He is also capable of telepathy, as there were a few incidents where he communicated with Shadow or multiple people yet was nowhere to be seen, and he also uses telepathy through Doom's Eye.

Black Doom's ability to create illusionary copies of himself.

While engaged in battle, Black Doom can summon and throw flaming meteors[3] towards enemies with devastating force and use a vertical disc attack[4] that can slice partially through large obstacles. His aim with these weapons is recognized by many characters as having deadly precision, along with "swift strike", a long, sideways, light-blade boomerang[5][6] which spins around at floor level and bounces against obstacles.

Devil Doom

Devil Doom is the true form of Black Doom, who appears as the final boss of Shadow the Hedgehog. Black Doom can transform seemingly without needing the Chaos Emeralds or any other external power source to do so. While he is in Devil Doom form, he still can use Chaos Control, but adds the abilities to seemingly telekinetically rip up entire roads and buildings, and hurl them at Super Shadow. He can also breathe fire and summon floating, rock-like spheres that fire lasers.

Shadow the Hedgehog

Black Doom and Shadow.

The relationship between Shadow the Hedgehog and Black Doom may have been brief, but it has played an important role in Shadow's life. Shadow was made of Black Doom's blood, in a deal between the alien and Professor Gerald; this technically makes Shadow Black Doom's biological son. Black Doom even states that being a part of his blood, Shadow is more akin to him than he thinks.

Black Doom constantly follows Shadow throughout his invasion of earth, trying to get Shadow to see what he believed to be the truth about humanity and that they needed to be punished. Even after Shadow opposes him several times, Black Doom still insists on trying to get Shadow to join him, turn on humanity and see things his way. He even persists to do so as they fight in their final bout well after his plans have gone into action, suggesting Black Doom really did have a genuine attachment to Shadow. Black Doom sought to open Shadow's eyes to their wrong doings in order to get him to realize humanity deserved to be punished for their terrible nature and selfishness, something he does even to the bitter end during their final bout. He even tried to put Shadow on his side by playing with what was left of Shadow's painful memories of losing Maria. Regardless of the path taken during the incident, Shadow defeats Black Doom and destroys Black Comet along with Black Arms.

Throughout the events of the Black Arms incident, Black Doom threatens Shadow and demands extreme loyalty and respect without compassion, even when it helps. Nor does it tolerate any type of error or failure, no matter how difficult Shadow's task may be. In the end, Shadow refused to help him and decided to put an end to his biological father and his "offspring" after learning of his true plans.

Archie Comics

Black Doom, from Sonic Universe #59.

In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, Black Doom had a similar role to the one in the games. Like in the games, Black Doom worked with Gerald Robotnik to create Shadow the Hedgehog for his own hidden agenda of conquering Mobius. However, when the time for Black Doom's return came, both he and the Black Arms ran afoul with a rival group of conquering aliens, the Xorda which they engaged in a galactic war.

In the reality created by the Super Genesis Wave, Black Doom and the Black Arms made their return trip to Sonic's World and were destroyed by Shadow the Hedgehog. In the event of his death though, Black Doom left behind a successor named Black Death to finish a conquest on another planet; as such, the Black Arms endured under Black Death, who made plans to return to Sonic's world to finish what Black Doom started.

  • Black Doom (as Devil Doom) is the first and only villain Super Shadow battles and defeats on his own.

  • Black Doom still appears to aid Shadow even when he takes the hero's side of the story up to the point where he fights him, despite Doom's stated intolerance for insubordination. This is due to the game's choose-your-own-path structure, which often causes storyline inconsistencies.
  • Black Doom bears a resemblance to Wizeman from NiGHTS, another Sonic Team franchise. Both characters share a "blood relation" to their respective protagonists, wear similar clothing, and lack legs. The two also share a similar power, in that Black Doom can send his third eye to watch people, whereas Wizeman uses one of his many hands, which have eyes in the palms.
  • The way Devil Doom falls after he is defeated by Shadow is similar to Metal Overlord's defeat in Sonic Heroes. Although Metal Sonic has survived, Black Doom is seemingly killed in the battle.
  • Whenever Shadow is battling Black Doom, he is partnered with a team leader from Sonic Heroes (Sonic, Vector or Rouge).
