Charlie is the Dangerous Emissions Supervisor of Sector 7G at the Springfield Power Plant. He is a friend of Homer.
Charlie is known to have bad luck. He is arrested for threatening to beat up local officials over the slow progression of HDTVs. He was briefly disabled as stated by Lenny after Homer notices he is not at the plant. However, he later recovered. He, along with other employees, were also set on fire due to Homer's negligence. As a member of the Springfield Nuclear Power Plant softball team, Charlie uses his sister's wooden leg as a baseball bat.
Charlie is replaced by Mindy Simmons after he, Homer, Lenny, and Carl play a prank on a worker and cause a radioactive gas leak and Charlie complains to Mr. Burns that the plant requires a real emergency exit rather than one which is painted on. Burns lowers a giant tube which suck Charlie up, sending him to an Asian country where he is forced to dance on a table.
 Characters in The Simpsons
Charlie bears a resemblance to Sam, one of the barflies at Moe's Tavern. This could be because they both have big glasses, they both have trouble with alcoholism, they have scruffy looks, worried eyes, and have bags under their eyes. They also occasionally are seen hanging out at Moe's Tavern as well.
 Characters in other media
In Matt Groening's second show, Futurama the character Terry appears to resemble Charlie including his primary role of being a background filler and his usual role of having bad luck.
He is voiced by Dan Castellaneta, who said that he was "just [doing] an imitation of Lenny", according to the commentary for "Homer at the Bat". His voice sounds similar to the Blue-Haired Lawyer and Arnie Pie, who are also voiced by Castellaneta.
