Sonic the Hedgehog (character)

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 hero of the video game series released by Sega, as well as numerous spin-off comics, cartoons and books.

History
The first game in the franchise was released on June 23, 1991 in order to provide Sega with a mascot to rival Nintendo's flagship character Mario. Since then, Sonic has become one of the world's best-known video game characters, with his series having sold millions of copies. In 2005, Sonic was one of the first game character inductees into the Walk of Game, alongside Mario and Link.

Artist Naoto Ōshima, designer Hirokazu Yasuhara and programmer Yuji Naka are generally credited with the creation of the character, a blue anthropomorphic hedgehog, who has the ability to run faster than the speed of sound. This is a major part of the gameplay of the series.
