Sonic is a anthropomorphic hedgehog born with the ability to run faster than the speed of sound, hence his name, and possesses quick reflexes to match. As his species suggests, Sonic can also transform into a concussion ball, primarily to attack enemies. Sonic is a slender, anthropomorphic hedgehog with blue fur covering most of his body, peach-colored skin covering his arms, snout, and front torso, and emerald green eyes. He has six long spines on the back of his head, two spines protruding from behind his shoulders, and a short tail. Sonic wears a pair of red, friction-resistant sneakers with white parts around the ankles, gray soles, and white straps on top, the last of which is fastened by a gold buckle on each foot. He also wears a pair of white gloves on his hands. They say Sonic is "like the wind"; a wanderer who is always on the move and known for his free spirit and adventure. He values freedom above all else and strives to live his life according to his own rules, not the standards of those around him or out of heroism and duty, never thinking twice about what other people say or think. Born to run, what Sonic enjoys most is traveling the world. Endowed with a strong passion for enjoying life, he never stays in one place for long and always moves on to seek his next challenge, making his life an endless series of adventures. Because of his need for freedom, Sonic hates the idea of being restricted, and being confined for too long makes him nervous and restless. Sonic's demeanor is always laid-back, cool, and carefree. However, he is often impatient, hates boredom, and sometimes has a short temper. Because of his impulsive nature, Sonic can be reckless and quick to act before thinking, throwing himself into trouble without a second thought and without heeding the warnings of others. Nevertheless, he is honest and always keeps his promises.
