Sonic The Hedgehog

Sonic the Hedgehog (ソニック・ザ・ヘッジホッグ, Sonikku za Hejjihoggu, trademarked Sonic The Hedgehog, is a video game character and the main protagonist of the Sonic video game series released by Sega, as well as in numerous spin-off comics, cartoons, and a feature film. The first game was released on June 23, 1991, in order to provide Sega with a mascot to rival Nintendo's flagship character Mario (see 1991 in video gaming). Since then, Sonic has become one of the world's best-known video game characters, with his series having sold more than 80 million copies. In 2005, Sonic was one of the first game character inductees into the Walk of Game, alongside Mario and Link.

While many individuals at Sega had a hand in Sonic's creation, programmer Yuji Naka and artist Naoto Ōshima are generally credited with the creation of the character, a blue 15-year-old anthropomorphichedgehog, who has the ability to run at supersonic speeds and the ability to curl into a ball, primarily to attack enemies. This is a major part of the gameplay of the series
