Sonic is a slim anthropomorphic hedgehog with blue fur that covered most of his body, peach skin that covered his arms, muzzle, inner ears and front torso. He has emerald-green eyes, a black nose, and small, triangular ears on the top of his head. He also has three long quills on the back of his head, two spines protruding from his back behind his shoulders, and a short, pointy tail. For attire, Sonic wears two light-weight, hyper friction resistant red sneakers with white cuffs around the ankles, gray soles, and white straps across the top, the last of which were held down by a gold buckle on each foot. He also wears a pair of white gloves with sock-like cuffs on his hands. Sonic is a habitual daredevil who is kind, funny, loyal, honest to his friends, keeps his promises, and dislikes tears. He took the young Tails under his wing like a little brother. He is mostly seen napping, running towards an adventure or thwarting Dr. Eggman's attempts at world domination. In times of crisis, though, he focuses intensely on the challenge as if his personality has undergone an astonishing change, and mostly he is fearless. In some instances, Sonic is shown to be an isolationist and slightly antisocial as he is the kind of person "that needed a lot of privacy," preferring to be alone either by napping, looking at the horizon, or going on an adventure alone for a few minutes or for over six months; ignoring his friends when engaging in conversation or going on an adventure themselves to a location he was to. Also, Sonic is a nature lover, seeing as he preferred to be outdoors than indoors and take the time to smell the flowers and enjoy life. Despite his positive attitude and strong need for privacy, Sonic displays some loneliness when he first arrived on Earth, believing that he was the only one being transported without his friends and felt sad about it for a moment. Sonic has also shown himself as a bit of a trickster, as seen when he was stuck on a cruise with his friends, where he manipulated the others to return back by deceiving them that their loved ones at home were missing them.
