Sonic is a habitual daredevil who is honest, loyal to friends, keeps his promises, and dislikes tears. He took the young Tails under his wing like a little brother when the fox was 5. With Knuckles, he shares a friendly rivalry (similar to the game one), but the two can be great teammates, though Sonic simply can't resist teasing him whenever he has the chance to. When not training, Sonic is known napping, watching television or running.
Sonic's main ability is obviously his high speed, rivaling that of Shadow's, them being the fastest in the series so far. His battle style is often used very well in conjunction with his speed. In battle, Sonic's attacks primarily consist of numerous kick combos, and rarely hitting anyone with his fist. His trademark attack, which allows him to curl up into a ball and slam into his oponents, is a prime example of the way Sonic fights. This rolling ability, with enough speed, can even cut through steel. It is possible that Sonic, though not often seen using much arm strength, may be stronger than he appears. He can use the Chaos Burst or less the seven Chaos Emeralds to activate a suppressed Super form. Sonic can use Chaos Control and such with the help of a Chaos Emerald.
