This is a cool picture of Sonic the Hedgehog! He's a super famous video game character. You can tell it's him because he's bright blue, has pointy spikes on his head, big green eyes, and a little tan snout. He's wearing white gloves and red and white shoes with a gold buckle.  

Sonic is known for being incredibly fast! He can run super speedy and zoom all over the place. He's usually got a friendly but determined look on his face, like he's ready for an adventure. In this picture, he's standing with his hands on his hips, looking confident and maybe a little bit cheeky! He's a really fun and energetic character that lots of people love.
