Uncle Chuck

From Sonic Retro

Sir Charles "Chuck" Hedgehog is a character who appeared in almost every American-made Sonic the Hedgehog media. A knight of the Acorn Kingdom of Mobius, Sir Chuck the uncle of Sonic, was unwittingly responsible for the rise of the planet's cruelest tyrant. The creator of the roboticizer, a process that turns flesh into metal and robs an individual of his or her free will, Charles hoped to use this technology as a means of curing the sick and allowing people to live longer. The project was stolen by Warlord Julian Kintobor, who declared himself Robotnik and used it to enslave Mobians everywhere after taking control of the capital city Mobotropolis. Sir Charles was among the first to be roboticized. Years later, he regained his free will and was reunited with his nephew Sonic. He worked as a spy for the Freedom Fighters up until Robotnik's defeat.
