Sonic the Hedgehog is a mobian hedgehog endowed with the power of super speed and the ability to control the Chaos Emeralds. He is a slim, 16-year-old hedgehog with blue fur that covered most of his body, and tan skin that covered his arms, muzzle, insides of his ears and front torso. He had small, triangular ears on top of his head, six long quills on the back of his head, two spines protruding from his back behind his shoulders, and a short tail. For attire, Sonic wore lightweight, hyper friction-resistant red boots with white cuffs around the ankles, gray soles, and white straps across the top; the latter of which are held down by a gold buckle on each foot. He also wore a pair of white gloves with sock-like cuffs on his hands. Sonic is a cool blue dude with a sassy attitude. He is not a "do-gooding" hero, but is loyal to his friends and has a good sense of right and wrong. He is someone who plays by his own rules, while maintaining a strong sense of justice. He is very independent and is mostly interested in doing his own thing. He is not book smart, but is very street smart. He is generally impatient, impulsive, and sometimes has a hot temper. He likes to get things done quickly and is not very detail oriented. Despite how he considers himself a bit of a Casanova, he doesn't dedicate his life to romanticized ideals. He loves beauty, nature, and adventure.

Glancing back, he saw a young fox who quickly hid when caught staring. Shrugging it off, he sped away, only for the fox to trail him again. Later, while chasing Eggman, Sonic spotted the fox once more—this time noticeably more determined. To his surprise, the little fox could keep up with him. Not minding the company, Sonic let him tag along while keeping an eye on him. This was how Sonic met Miles Prower, nicknamed “Tails,” and from then on, Sonic let Tails keep his Tornado.
