Sonic is the fastest thing alive. Using his immense speed, he foils the plans of the evil Dr. Eggman and his robot army. His attitude can changeon a whim, as he can be pretty lazy as well as quite competitive. He can be goofing around one minute and dead serious the next, given the right circumstances. But the one constant is the way he feels about his friends and he'll do all in his power to keep them, and the world, safe.
