Which Sega character was announced for Super Smash Bros. Brawl in October 2007?

Sonic the Hedgehog was the Sega character announced for Super Smash Bros. Brawl in October 2007. His inclusion made him one of the first playable characters from outside Nintendo’s own franchises to join the series.

Nintendo revealed Sonic on October 10, 2007, through the official Smash Bros. Dojo website. His arrival was especially notable because fans had requested the Sega mascot for years. Sonic’s longtime rivalries with Nintendo’s Mario and other game heroes made the announcement a major crossover moment.

Sonic could not be added to Super Smash Bros. Melee because the development team reportedly lacked enough time. Brawl’s larger production and expanded third-party ambitions finally made his inclusion possible. Konami’s Solid Snake was also playable in Brawl, making the game a landmark entry for guest fighters.

The other options are Sega-related characters, but none was announced as a playable Brawl fighter in October 2007. Miles “Tails” Prower, Knuckles, and Shadow appeared in other forms or later discussions, while Sonic was the confirmed character.
