Sonic and Shadow.

Shadow - He has black hair and orange eyes. He wears a white T-shirt and a black jacket over it. He accessorizes with a black choker. He's reserved, goal-oriented, and prone to radical decisions, but not without a sense of duty. He rarely shows his good side, and so he's usually cold. (But he treats you well, just like he does your dad, Sonic.) But he can be arrogant and stubborn. Sonic - He has blue hair and green eyes. He wears a blue T-shirt and a white jacket over it. He is good-natured, carefree, sociable, hot-tempered, and impatient.
