Shadow is an artificial created life form in the design of a male, anthropomorphic hedgehog. He resembles Sonic in many ways, such as how his hover skates propel him at extreme speeds to rival those of Sonic; but he distinguishes himself with greater use of his signature ability to use Chaos Control with Chaos Emeralds. He is Sonic's rival and is the anti thesis of Sonic himself in all aspects of Shadow's life. The rings attached to his wrists suppress his power. Shadow vowed to keep his promise to Maria, a girl he befriended on the Space Colony Ark, to give humanity a chance to be happy. He once blamed humanity for Maria's death, but came to realize that Maria wanted the people on Earth to live happy lives.

He has the Musica family tattoo on his left shoulder. When he was young, Musica's family was wiped out by Lance the "Beast Sword" of Demon Card, with a sword forged by his grandfather, Galein Musica. He was then taken in by Rize, a silver-claimer, who raised him and taught him the ways of silver-claiming. On Rize's deathbed, he asked Musica to find Silver Ray and destroy it, to which Musica agreed. Musica later discovered that the Oni Fortress River Saly was in fact the Silver Ray in disguise.
