Sonic The Hedgehog is a character owned by Sega corp. He's currently the only animal known for his speed, and drug dealers are worried that he's stealing their fire.
This guy here? He runs fast and shit.
In the early 90s, Mario was making Nintendo filthy rich. They were selling systems and games faster then the speed of sound. Sega, having no official "Mascot" to call their own, wanted to cash in on this money making scheme. Naoto Oshima thought the greatest way to be beat something that's selling fast, was to creat something fast. Some cute little blue bastard that could go supersonic.
Thus, Sonic the hedgehog was born. Or something like that.
To distract you from my fact checking, here's a kitten enjoying a drink.
