Sonic the Hedgehog

Sonic the Hedgehog is a character created by the Japanese game designers Yuji Naka and Naoto Ohshima. He is the star of the Sonic the Hedgehog franchise and the mascot of the Japanese video game company Sega. Sonic is an anthropomorphic blue hedgehog who runs at supersonic speed. He races through levels, collecting rings and avoiding obstacles, as he seeks to defeat his archenemy, Doctor Eggman. He is accompanied by supporting characters, such as his sidekick Miles "Tails" Prower, love interest Amy Rose, and rival Knuckles the Echidna.

Sonic made a cameo in the arcade game Rad Mobile (1990) before starring in Sonic the Hedgehog, a platform game for the Sega Genesis, in 1991. Sega sought a mascot to compete with Nintendo's Mario, and Ohshima designed Sonic based on a prototype programmed by Naka. Sonic's design was influenced by a variety of sources, including Felix the Cat, Mickey Mouse, Michael Jackson, and Santa Claus; his pigmentation was chosen to match Sega's cobalt blue logo. Yuji Uekawa redesigned Sonic for Sonic Adventure (1998) to suit the franchise's transition to 3D computer graphics, with a more mature look designed to appeal to older players.
