Charles Limekiller was a bum of apparent Australian origin who sought room and board at the Bloom Boarding House. When he was first introduced, it was revealed that Limekiller had been estranged from his wife, Eleanor and their three children. Initially, Major Bloom disapproved of having him around, but Bess was so enchanted by Limekiller's usage of French that he had no choice but to let Limekiller stay (even though what he actually said was "Something like 'Your earlobes resemble fish heads'"). Limekiller would later reappear as the Meadow Party's first presidential nominee in 1983. However, his nomination was short-lived; after taking an impolitic jab at his campaign committee, "a black, a woman, two dips and a cripple" (a commentary on then-Secretary of the Interior James G. Watt), he was dropped from the Meadow ticket before the actual election year had even come. He disappeared shortly thereafter.
Originally, Limekiller was depicted as a somewhat nattily dressed bum, including a battered top hat, and wore a pair of sun glasses. Breathed would later describe him as "a sloppy retread of Doonesbury's Duke. When he was reintroduced for the presidential race storyline, he was changed, presumably to better distinguish him from Steve Dallas. The sun glasses were abandoned, his clothes became the more standard attire of a homeless man, and he now had a jutting chin covered with stubble. It was at this time his Australian accent was introduced, whereas before he'd faked a learned manner of speech when he spoke.
