Sir Charles Hedgehog

Sir Charles Hedgehog (William Windom) - Known as "Uncle Chuck," he is an elderly inventor, as well as Sonic's warmhearted uncle. Chuck invented the roboticizer to allow people to live longer, but it had the unintended effect of robbing an individual of their free will. Robotnik later stole it and used it on him, turning him into one of many mindless drones and destroyed his "restaurant", Uncle Chuck's Chilli Dogs. With great difficulty, he regains control of his body and acts as a spy for the Freedom Fighters.
