Billy is a character that appears in the Sonic the Comic series published by Fleetway Editions. An anthropomorphic dog, he was one of thirty-five Emerald Hill Folk incarcerated in Robotnik's Badnik Processing Plant.
He was horrified at the prospect of being led away to be turned into a badnik "like lambs to the slaughter", and freaked out. He tried to escape, diving for the stairway, but he was caught by the lizard overseer's whip and dragged back. He was rescued with the other inmates by Sonic and the Freedom Fighters, and re-located to the Mushroom Hill Zone on the Floating Island, to be with the rest of his people.
