Anthropomorphic character

Sonic the Hedgehog

Sonic is a blue anthropomorphic hedgehog who has the ability to run at supersonic speeds and the ability to curl into a ball, primarily to attack enemies. Throughout the course of the video games, Sonic most commonly has to race through levels, collect power up rings and surviving against a host of natural obstacles and minions to achieve his goal and reach the end. Sonic's programmer is Yuji Naka and artist is Naoto Ohshima.
 


The natural colour around his mouth, eyes, body and arms give him human like features and more realistic to a hedgehog than blue.
Bright blue hedgehog with large proportioned feet and hands to exaggerate how fast he's running whilst playing the game, his shoes are also red in contrast the his blue body making them stand out more.
His aerodynamic head/hair shape also helps the idea that he is "the fastest hedgehog in the world". 
He is turned into an anthropomorphic hedgehog by adding the body features of a human, and big cartoon like eyes and given a strong personality, of that of a humans.
