Black Arms



The Black Arms are a demonic alien race led by Black Doom. They appear in the game Shadow the Hedgehog, where they invaded Earth for search of the seven Chaos Emeralds, and are battled by the game's main character Shadow the Hedgehog, along with other characters. They are commonly referred to as "the black creatures", "black aliens" or even "terrorists" as the inhabitants of Earth do not know their real name.

Shadow the Hedgehog
The Black Arms are out to collect the Chaos Emeralds so that they can use Chaos Control to teleport their Black Comet to the Earth's surface, where it digs into the planet and releases a toxic gas that paralyzes all life (except those with Black Arms DNA). It is unknown what the Black Arms plan to do with Earth after conquering it.

The Black Arms launch a surprise invasion of Earth in the beginning of Shadow the Hedgehog, and destroy everything in their way while searching for the Chaos Emeralds. They are immediately opposed by the heroic Sonic the Hedgehog and his friends, the military organization GUN bent on protecting the planet, and even Doctor Eggman, who is usually the antagonist in the Sonic games. Throughout the game, the player controls Shadow the Hedgehog, and can choose whether to help the Black Arms with their invasion, or to defend the Earth along with the other characters.

No matter what the player chooses to do, the game has a "final ending", where Black Doom obtains the Chaos Emeralds and warps the Black Comet to the planet's surface. Shadow opposes the Black Arms, becoming Super Shadow and defeating Devil Doom, a powerful mutated form of Black Doom. He then proceeds to use Chaos Control to send the Black Comet into space again, where he blasts it with the Eclipse Cannon on the Space Colony ARK, destroying it along with the brunt of the Black Arms residing inside it.

Sonic the Hedgehog (Archie Comics)
The Black Arms were introduced briefly in the Sonic the Hedgehog comic book when Sonic, Tails, and Knuckles traveled to Argentium, home of the Bem aliens. Their mission is to retrieve Tails' parents, who had been trapped on "Wheel World" for some time, and their transportation was provided by the magic of Merlin Prower, Tails' uncle. The planet was in ruins and in the sky were ships from the Xorda, another evil race. Sonic immediately recognized them, but couldn't recognize the ships they were fighting. Tails' parents, Amadeus and Rosemary Prower, tell Sonic that the ships belong to the Black Arms before they are returned to Mobius.

It was eventually revealed that the Black Arms and their leader Black Doom played a big part in Shadow's creation, very similar to their video game counterparts. However, while Black Doom wanted to use Shadow as his greatest weapon, Professor Gerald intended for Shadow to become the ultimate protector of Mobius. With the war between the Black Arms and the Xorda still going on, it remains to be seen when or if the Black Arms will appear again and invade Mobius.

Black Doom
Black Doom is the evil overlord of the Black Arms, and the only one with the ability to speak English. He has three eyes and seems to float above the ground, wearing a cloak with metal ornaments. He helped Gerald Robotnik create Shadow The Hedgehog, by using his own blood. He has lived for over 2000 years, and planned to use the human beings as an "energy source", possibly food for his larvae. He was eventually defeated by Shadow. Black Doom can separate from one of his eyes, transforming it into a tentacled entity known as Doom's Eye that serves to do his bidding.

Black Arms
Members of the alien arms that invade earth under Black Doom's command. They will attack Shadow, even if Shadow attempts to complete one of Black Doom's missions. Members of the Black Arms include the Black Warriors, Black Oaks and Black Arms Annelids. The following is a list of creatures in the Black Arms.

Killer Plant
The Killer Plant is a giant moving plant lifeform, apparently mutated by the Black Arms as the aliens themselves do not have plants. It can breath fire and extend its branches. Once defeated, it will temporarily shrink into a harmless bud, but it will revive again if given enough time. No points are awarded for killing it.

Shadow the Hedgehog

 * Main article: Shadow the Hedgehog

In theory, Shadow is part Black Arms alien, having been created with Black Doom's blood. However, he's not a part of their army, rather a secret weapon, although he didn't know this fact himself until the final story in Shadow the Hedgehog. The efforts of Shadow have finally put an end to the Black Arms' reign of terror.

Air Saucers
One-manned floating discs that can be used to cross hazardous surfaces, such as toxic water. Upon analyzing one, E-123 Omega is astounded that it floats without using either fuel or engine components.

Black Tank
A powerful Black Arms Tank that appears in the Lethal Highway stage and somewhat resembles a stealth bomber. The tank is surrounded by a shield that can withstand many attacks, but it is oddly enough unarmed, possibly it is not a tank but simply some kind of armored troop transport for the Black Arms. Destroying it is the Hero mission on Lethal Highway and the best way to defeat it is using a rapid-fire weapon, preferably from the Black Arms. The most effecttive weapon is the Shadow rifle and the Gatling gun which can be obtained behind the five-key door, with the maximum of 40 ammo can easily take out the tank in below 10 seconds.

Gunships
Large organic-looking battleships. They usually appear in the Black Comet, Final Haunt and the Last Way stages. Gunships are armed with a Black Cannon and can spawn enemies. The best way to attack these ships is to use nearby cannons or the shadow rifle.

Black Comet
The Black Comet is a comet that passes by the Earth every 50 years. It is the home and/or a mode of transport for the Black Arms. The comet itself appears to be alive or techno-organic in nature, most notably when it was teleported to Earth and seemed to take on a life of its own and dig into the surface. When inside, it is almost like being in the body of a living organism. There are pulsating growths and what appear to be tentacles, organs and throat-like halls and many organic sounds such as in the japanese version of the game, when the tentacles are destroyed, a roaring (vey similar to the Biolizard's) can be heard. There is a vicious substance in the comet that only death leeches and worms can exist in. Even Black doom continuously warns Shadow that "that toxic substance is fatal". The tentacle-like projections also appear to exist in the substance.

The last time the comet passed by Earth, Black Doom made a pact with Gerald Robotnik in order to create the Ultimate Lifeform, Shadow the Hedgehog. Shadow would help Gerald in his research and would help Black Doom in his quest to collect the 7 Chaos Emeralds. Gerald, however, designs the Eclipse Cannon to destroy the Black Comet when it returns. 50 years later, as the Black Comet approaches Earth during the start of Shadow the Hedgehog, the aliens begin the final phase of their mission to collect the 7 Chaos Emeralds and enslave the humans. The Black Comet does not have enough speed to make it to Earth's surface on its own, so Black Doom uses the power of the Chaos Emeralds to teleport the comet to Earth. However, Black Doom's plans are foiled when Shadow teleports it back out into space and uses the Eclipse Cannon to destroy the Black Comet and all of the Black Arms inside of it.

It's interesting to note that while the Pure Hero level Final Haunt, the Black Comet (predictably)is full of Black Arms, on the Semi-Dark final level Black Comet, it's full of Gun Robots, and there are few (if any), Black Arms present.

Glyphic Canyon
Black Doom transported a long complex of temples to the Glyphic Canyon 2000 years prior to the games (notably, from a scientific perspective, all the planets were lined up at zero point 2000 years ago). According to Black Doom, it is the Black Arm's holy ground. These bird-shaped ruins were sealed away and deactivated many years ago. In order to reawaken this temple, one must touch the five large jewels within in it. "Reawakening" the temple makes it airborne, with the various pieces being held together with red laser-looking beams. If one destroys the jewels after this, the temples lose their power and fall down to the earth again.

Activating the jewels for Black Doom is the Dark mission for the "Glyphic Canyon" stage, while destroying them is the Hero mission for the "Sky Troops" stage, where Dr. Eggman battles the flying ruins with his Eggman Fleet. The temple is automatically reawakened when Shadow reaches Sky Troops, regardless of whether or not he has personally touched the five jewels, suggesting that the "evil path" through Glyphic Canyon is the canon route, or that the Black Arms activate the jewels themselves if Shadow doesn't do it for them.

There are also large tornado-like whirlwinds and dust storms in the ruins, that according to Black Doom were set in motion to stop humans from accessing them.

 * The Black Arms are currently the only aliens to appear in the Sonic the Hedgehog game series, as well as the most evil aliens in any form of the Sonic franchise, though the Xorda could be a close second in the Archie Comics continuity.
 * The Black Arms have recently appeared in the Archie continuity. They are having an all-out war against the Xorda near the planet of the Bem.
