Experiment 91. He's blue, he's fast, and he's a celebrity. While his heroic work is mostly confined to Station Square, there have been news stories about him all over the globe. The public can't just ignore a talking blue hedgehog who can travel faster than sound.

Of course, when you're used to speeds like that, it's pretty easy to get bored, so Sonic is quite impatient. He's good at heart, though, and when there's someone in trouble, he's quick to answer the call. REAL quick.
