Sonic is the world's fastest hedgehog, capable of running at the speed of sound (768 mph). His other abilities include a "Spin Attack", a 'Spin Dash" and his "Super Sonic" transformation - which makes him indestructible and gives him the gift of run-flight. Sonic is not an expert swimmer, but is fearless - even of Dr. Eggman. Alongside his best friend Tails, Sonic runs around the world stopping Dr. Eggman's schemes. He drives the Speed Star - a car built by his friend Tails - it helps to make a fair race as no one can beat sonic on foot.
