Shadow the Hedgehog is a 2005 video game developed by Sega Studio USA, the former United States division of Sega's Sonic Team. Featuring the titular fictional character Shadow the Hedgehog from Sega's Sonic the Hedgehog series, the game was revealed at the March 2005 Walk of Game inauguration of Sonic, the series' main character. Shadow the Hedgehog is the third game (and the last in the Sonic series) developed by Sega Studio USA, which was merged back into Sega's Japanese division in early 2008.

Following the trend of recent Sonic games such as Sonic Adventure and Sonic Heroes, Shadow the Hedgehog is a 3D platform game. Most levels have three possible missions—"Hero", "Dark", or "Normal"—that the player may choose to complete; some levels have only two (which mostly are only "Hero" and "Dark"). The missions completed determine the game's plot, a feature referenced by the game's tagline, "Hero or villain? You decide." The plot centers on the attempt of Shadow, a creation of Doctor Eggman's grandfather Gerald Robotnik, to learn about his past after suffering from amnesia. To defeat enemies encountered, Shadow can use various weapons and special attacks.

Shadow the Hedgehog was created for the Nintendo GameCube, PlayStation 2, and Xbox video game console, and released in 2005 in North America on November 15 and in Europe on November 18. It received mixed to negative reviews; critics criticized its unwelcome "dark" theme, particularly the addition of guns and other weapons, but praised its replay value.

Shadow the Hedgehog is a platform game that incorporates elements of action-adventure gameplay. Like previous games in the series, basic gameplay involves running quickly, collecting rings, and destroying enemies. As is standard in the series, Shadow collects rings as a form of health; when he is attacked by an enemy, his rings bounce in all directions. If he is hit by an enemy and has no rings, he loses a life. Levels are completed by undertaking missions, labeled "Hero", "Dark", or "Normal". whereas the Dark missions involve tasks for the Black Arms or Doctor Eggman. The Normal missions involve simply reaching the Chaos Emerald, or goal, at the end of the level. Each level features cut scene to advance the story, and several also feature boss battles.

Black Doom has not been a contender in any CBUB matches.
