Billy Kane is a character in both the Fatal Fury and The King of Fighters series. His family name, Kane, is meant to be pronounced like "Kon" or "Kaan" with a silent "e" (as in James Caan, an American actor), rather than the word "cane". He fights with a three sectional staff that he somehow can ignite with fire and can be split into three parts connected with a chain. He always tries to look out for his little sister Lilly Kane.

While Billy cannot be considered a 'good guy', he is not an evil man. His criminal career is motivated more by a desire to make easy money and his respect for Geese Howard than actual malice.
