A blue hedgehog that can run faster than the speed of light. He has a sidekick named Tails, who is an orange fox that can run fast too, but not as fast as Sonic.
Damn, Sonic ran so fast that I can't even catch him.

Sonic is another word for speed. Speed is amphetamine, a stimulating drug that triggers the brain’s reward system giving the user feelings of pleasure. Speed is not meth!
