Sonic the Hedgehog[a] is a video game series and media franchise created by the Japanese developers Yuji Naka, Naoto Ohshima, and Hirokazu Yasuhara for Sega. The franchise follows Sonic, an anthropomorphic blue hedgehog with supersonic speed, who battles the mad scientist Doctor Eggman and his robot army. The main Sonic the Hedgehog games are platformers mostly developed by Sonic Team; other games, developed by various studios, include spin-offs in the racing, fighting, party, and sports genres. The franchise also incorporates printed media, animations, films, and merchandise.
Naka, Ohshima, and Yasuhara developed the first Sonic game, released in 1991 for the Sega Genesis, to provide Sega with a mascot to compete with Nintendo's Mario. Its success helped Sega become one of the leading video game companies during the fourth generation of video game consoles in the early 1990s.
