Devil Doom

"I gave you life and yet you defy me? So be it! You will pay for your ingratitude with relentless pain!"

- Devil Doom to Shadow at the beginning of their battle

Devil Doom (デビルドゥーム) is an enhanced version of Black Doom. He is the final boss of the game Shadow the Hedgehog. Shadow eventually defeats him and saves the world after Sonic and the other Sonic characters cheer him on. He is voiced by Sean Schemmel and Ryūzaburō Ōtomo.

Physical Appearance
During the transformation, he becomes very large and much more intimidating; his body is almost completely changed. The only physical traces of Black Doom's original form is Doom's Eye and his horizontal horns. He has two heads on either side of his torso in the image of a gargoyle, and his lower half is rooted down to a large boulder. He also has horizontal mouthparts similar to the Black Bull, with the exception of an absence of a bottom jaw on both sides. Devil Doom has no eyes, but the Doom's Eye will exchange between heads to give them sight. Devil Doom's skin is red and black (the typical skin colors of the Black Arms), and he seems to have an extra finger on each hand. This also means his arms can operate from either side making his shoulders double jointed. His torso has strange spines pointing down.

Abilities
In addition to retaining the ability to use the Chaos Emeralds to induce Chaos Control, Devil Doom can breathe fire, manipulate objects and rocks from the city below to hover around him or impact enemies, and can make the rocks fire lasers. Devil Doom can also sense where Shadow is, as his attacks are of the same precision whether facing Shadow or not. Most of his body, with the exception of his Eye, is invulnerable and does not feel pain, even from a charged Chaos Spear. Devil Doom's wings are an oval shape, enabling equal use by both heads. Although, his wings can be crippled, making him vulnerable to side attacks, he can put either one of his wings in front of the eye to protect himself.

Battle
thumb|386px|leftThe battle is entered as Super Shadow. Devil Doom is floating in front of Shadow with a ring of debris. He may throw it at Shadow. There are ring balloons in the debris. After a while, he spits a wall of fire at Shadow, and the debris falls. He can also command the small rocks floating around him to shoot lasers. If Shadow is too close, Devil Doom will teleport away. Shadow uses Chaos Spear to attack Doom's Eye, which afterwards alternates between heads. When the debris is around him, go for the balloons and blow up the items around him for Chaos Blast, while attacking Devil Doom himself and the rocks gives Shadow Chaos Control. Shadow can also attack Devil Doom's wings to cripple him, as he can block attacks with them. Trivia
 * Even after Shadow disables his wings, Devil Doom will stay airborne.
 * Devil Doom is one of the few Final Bosses not to use the power of the 7 Chaos Emeralds for transformation. Doom says during the battle that he underestimated the power of the Emeralds.
