ハイスピードのヒーロー、ソニック！

character: sonic_the_hedgehog, classic_sonic. This pixel-art illustration shows classic sonic running from a three-quarter rear angle. His body is oriented toward the right side of the frame in a mid-stride running pose, with his left leg extended forward and right arm swung back for momentum. He has blue fur, a dark-tipped tail, and small rounded ears, wearing red sneakers and his signature white gloves. The shot is framed at a medium distance, keeping the full character visible against a crisp grid of alternating black and white tiles. Every pixel edge is perfectly sharp, with clean 90-degree angles and consistent spacing. Subtle grayscale shading defines the volume of his spiny quills and shadowed folds in his gloves and shoes.
