Abilities and aptitude :( 1). Thanks to his air shoes, Shadow is able to hoverskate at supersonic speeds, matching Sonic's right down to the last mile per hour. Conversively, Shadow doesn't need the shoes' jets to be as fast as his rival, but prefers them anyway, (2). Needless to say, his speed gives him awesome agility, acrobatic skills, and reaction time, (4). Though he can't compare with Knuckles, Shadow has enormous physical strength, capable of lifting objects many times his weight and size such as buses and large slabs of rock/concrete and flipping/tossing them with relative ease, (5.) Shadow has an incredible resilience to damage as it takes a LOT of major punishment for him to go down for the count. Even then, he recovers rather fast indeed. Given his ultimate life-form status, he may also be completely immune to disease and he does not physically age, (6). By removing the golden rings on each of his wrists, Shadow can release tremendous amounts of energy that were (presumably) "held back" by the rings in a speedy dash that appears to be able to obliterate almost anything in his path.

Hobbies and talents :( 1). Seems to be the most talented when tapping into the powers of the Chaos Emeralds, since he is most adept with Chaos Control and possesses an extensive array of Chaos Energy-related supernatural powers and abilities, (2). Experienced athlete, particularly in fields such as boarding and grinding, (3). Whether you like it or not, Shadow knows how to use a VERY wide variety of weapons and vehicles, (4). Also talented with many types of Extreme Gear.

Weaknesses: Despite being somewhat easily led when set on a goal, no known weaknesses.

Physical Appearance:
Coarse and close-lying black fur with a light grayish colored extremely thin undercoat. Appears very suede like in texture.
-Long and thin black-furred legs that broaden below the knees. Capable of allowing Shadow to perform some extremely impressive jumps and leaps and very powerful kicks.
- Red highlights on several parts of his body including his quills, arms, legs, and on the upper corners of his eyes. This coloration is implied to be an inherited trait from the Black Arms.
- Tan skin muzzle and inner ears
- Thin and wiry black-furred arms that have MUCH more strength than they appear to have at first glance
- Large, very serious looking eyes with ruby red irises, black pupils and glassy white sclera.
- Black eyelids with a thickish black lash that extends among the bottom of the top eyelid.
- 6 elongated quills coming out from the back of his head (the outer four are bent upwards) that appear to be consisted of many thousands of smaller spines, and two much less pliable arching quills on his back.
- Triangular, constantly alert and perked ears with a slightly forward slant. They have some degree of movement and are known to slant sideways when Shadow is upset.
- Long, shiny black nose with no apparent nostrils
- Small, slightly arched tail
- Triangular patch of tufted white fur on his chest.

Greatest friend(s): Maria Robotnik, Prof. Gerald Robotnik, Rouge the Bat and E-123 "Omega"
Enemy(s): Dr.Eggman(when necessary), ANYONE who gets in the way of his objectives.
Likes: Shadow enjoys silence, one-upping Sonic and just inspecting things without uttering a vowel. He also likes Space Colony ARK and has the utmost respect and loyalty for Professor Gerald Robotnik, as well as brotherly love for Maria.
Dislikes: People with a show-offy attitude (Sonic) or who get in his way tend to piss him off. Being constantly compared to or mistaken for Sonic is most likely an additional annoyance. He has a general dislike of mankind as well, but this doesn’t seem to prevent him jumping to their full, unshakable defense when/if he sees fit. Lastly, the only thing he fears more than anything his own power.
Favorite food(s): Unknown.
