Charles becomes Roger's right-hand man in "Roy Rogers McFreely" when his persona of the same name takes over the chairmanship of the Homeowners Association to get even with Stan for forgetting to get grenadine and not respecting him. He has a fire hydrant placed in front of Stan's house and has Charles tow away his SUV. He later drives a garbage truck with instructions to pick up the Smith's trash every day at 4:30am. When Stan questions this Roger tries to hide the fact that he is in the garbage truck giving instructions.
Charles makes other cameo appearances as well, including at the roller rink in "LGBSteve".
Charles is voiced by Alex Fernandez.
