—"Shadow the hedgehog★"

Sonic is an anthropomorphic hedgehog of vibrant blue. His body is slender and streamlined, designed to appear agile and fast. He has a large head in proportion to his body, and his long, pointed quills protrude from the back like stiff tufts of hair. Its face is expressive: large eyes (usually green), prominent eyebrows, and a confident smile. The muzzle, chest, and inner arms are a light beige, contrasting with the blue of the rest of the body. His arms and legs are slender; he wears simple white gloves and red sneakers with a white stripe and gray soles. Overall, his design conveys energy, speed, and a carefree attitude, as if he's always ready to take off.

Shadow is an anthropomorphic hedgehog with an intense and elegant appearance, with a design that conveys power and mystery. Its fur is deep black, crisscrossed by bright red markings that run along its quills, arms, and legs, as if its body were storing energy within. Its quills are long and sharp, angled backward, giving it an aggressive and aerodynamic silhouette. She has piercing red eyes, always with a serious and resolute expression. Her gaze is usually cold and focused, like that of someone who thinks before acting and carries a heavy emotional burden. On his chest stands out a tuft of soft, fluffy white hair, which contrasts with the dark tones of his body. She wears golden rings on her wrists and ankles, which act as limiters of her power. Her shoes are large and striking, red, white, and black, with a futuristic design that includes thrusters, allowing her to glide across the ground as if floating.
