Yea i'm gonna have to change my mind on that Blaze deal. I thought about the results and abilities. And Shadow possesses the same blistering speed and agility as Sonic and is similar to him in almost all other abilities. Although it was later revealed in Shadow the Hedgehog that he also has super strength (while not quite as much as Knuckles ) by overturning a bus with one hand. Shadow's trademark move is Chaos Control. Using the power of a Chaos Emerald, he can warp time and space. The Chaos Control is usually used to freeze time, or to teleport, from the point of view of those watching Shadow. He is only seen freezing time in Sonic Adventure 2 in 2 player mode, but in Sonic Heroes the time freeze is an effect of Team Dark's Team Blast. Aparently, it also allows whoever activated it to go from some place to anywhere else. Recently, it was revealed in Shadow the Hedgehog that Shadow doesn't necessary need a Chaos Emerald inorder to activate Chaos Control, and that the Emeralds merely amplify the space time control powers of that particular technique. This might have been a result of Shadow inheriting some of Black Doom's powers since they both share the same DNA, as Black Doom himself was able to perform Chaos Control without using a single Chaos Emerald.
In Sonic X, Shadow can carry Chaos Emeralds in his fur, the same way Tails puts the Chaos Emeralds in his tails. Moreover, it shows that if Shadow's power rings are knocked off, he will quickly lose energy and become weak. However, this is cut off in the dub.
In Shadow the Hedgehog, Shadow has shown that he can also use a wide range of close-combat weapons, firearms, semi-automatics and heavy assault weapons, improvise with debris, and drive a wide range of vehicles.
One of Shadow's assets are his Air Shoes (also called Jet Shoes and Hover Skates) which ultilize powerful hover jets to reduce friction and enable Shadow to 'skate' as fast as Sonic runs. Without them, it is possible that he may be as fast as Sonic, but there is no proof of this. The jets on both end of his shoes glow gold when he runs. In Sonic Riders, the Air Shoes have been redesigned by Eggman as Extreme Gear. Their qualities are overall the same.
