Sonic the Hedgehog, also known as the Blue Blur by his hardcore fans is nothing less than a household name, with more than 10 million game copies sold around the world.

Naoto Oshima based his character on a real live hedgehog. Sonic is mostly covered by blue fur. He wears a pair of red shoes in which it allows him to run faster than the speed of sound. He can curl up into a small ball and attack enemies by pouncing them over the head. Sources from the company's game character design, describes Sonic as a character compared to as the wind and a wanderer who loves to travel different places. Sonic loves freedom and doesn't want to be beaten around. He likes to travel fast and likes to explore around new places. As much as he loves to travel fast, he is a bit impatient to slower moving objects. He is easy going, loyal and honest to his closest friends. In times of great turmoil, he is there to help anyone who needs his aid.

Sonics' first game was released in 1991 on the platform game entitled Sonic the Hedgehog sometimes called as Sonic 1. His first game had him racing down in roller coaster tracks and collecting gold rings in the process.The game play is simple. The player controls Sonic as he races down the tracks. In order for Sonic to overcome the obstacle, the player needs to provide a strong boost in order for Sonic to traverse the track loops prepared for him. Gold rings are spread across the tracks for the player to collect as much to gain him a few extra lives. The tracks may be filled with booby traps like spikes and flame cannons to prevent Sonic from progressing. Just like any other games in the market, it has that winning formula where you battle level bosses to further progress in the game.
