Dr. Eggman is a tall, thin figure with a large head and a long, crooked nose. His eyes are small and beady, and his bald head is framed by a few wisps of hair at the sides. He wears a vivid red and yellow suit with a black belt and black boots. On his back is a large metal contraption and in his left hand he holds a large metal staff. To colour this image, I'd suggest making him a bright, vivid shade of red and yellow, highlighting his outfit with a darker shade of yellow and black. His metal contraptions and staff can shine a silver or silver-gray. His pale skin can be a light shade of beige. His eyes can be a dark brown, and his wisps of hair a stroke of black.
