Sonic's general appearance involves his trademark blue color, with a peach muzzle, arms, and belly/chest. He has black eyes, and his quills are slicked back and styled somewhat like a mohawk. From behind, it looks like he has six quills, and two more on his back above his tail.
His general attire consists of his trademark red and white sneakers with a gold buckle on each, plus cuffed socks and white gloves.
Sonic's personality can be described as "one whose heart follows the wind wherever it blows". He's always on the move, never standing around in a single place for too long, and can often be seen tapping his foot impatiently while waiting to go somewhere. A drifter, he's always seen running around looking for his next adventure, whatever it may be.
Cool, carefree, and easygoing, Sonic is able to make friends easily. However, he also has a short temper, is impatient, and despises boredom. Sonic's reckless nature often makes him leap without looking into danger. Despite this, he's no liar, and keeps his promises no matter what.
A freedom fighter who passionately hates evil, Sonic is a loyal speedster who will stand by the side of good to the very end. Always ready to leap in and save the day at a moment's notice, Sonic also has the capacity to be serious when the situation calls for it, becoming intensely focused on the task at hand. Possessing a big heart, Sonic is always ready to help out any in need.
Possessing an ego to match his healthy self-confidence, Sonic tends to crack jokes and act snarky to lighten the mood. He also takes any moment he can to taunt his opponents, and has a good time doing so. However, he can also be a gentleman when he feels like it, and never lets past events get him down. No matter what has happened, he holds no regrets, and looks forward to the next adventure. Sonic also has a heroic will made of iron, allowing him to stay steadfast even when others can't.
Incredibly loyal to his friends, Sonic often leaps into action in order to protect his allies, often without consideration. At times he may leave them hanging or even put them in harm's way due to his fast-paced attitude, but he doesn't do this intentionally. Sonic is also willing to accept help from others, and tends to show great trust in them.
Sonic was raised by his Uncle Chuck in Mobotropolis, during the reign of the King. As a child, Sonic used to play with his friend, Princess Sally. Sir Charles was a top inventor of the kingdom and a personal friend of the King. Following the Great War, a warlord named Julian (later known as Doctor Robotnik) orchestrated a coup d'état and banished the King to the Void. Julian then renamed himself Robotnik and ordered that all citizens of Mobotropolis be roboticized and transformed into mindless slaves. Sonic and Sally, along with several other children, were spirited out of the city and hid inside a woodland camp that would eventually become Knothole Village. At the same time, Uncle Chuck fell into Robotnik's hands and was roboticized. Sonic remains frustrated by his inability to free his uncle from Robotropolis.
Powers and Abilities
Sonic's greatest strength is his running speed, with the ability to run at least at supersonic speed.
Sonic's main maneuver is curling into a spiky ball, which is a variant on the tendency for hedgehogs to roll into tight balls for protection, thereby turning himself into a buzzsaw that can cut through nearly anything. He is also able to harness the forces of the Power Rings, which charges up his strength and super speed to such levels that he creates an explosion upon dashing off.
