Pan Fendar was born on the planet of Dagobah some ten or so years before the beginning of the Clone Wars. His biological parents were a unknown person who crashed his ship on Dagobah and a scrange, an evil, carnivorous monster on the planet. The series of events that led to it was certainly unlikely, for scrange generally eat humans. Nobody knows what happened to Pan's human father after making the scrange who became Pan's mother pregnant. He was probably eaten, or something.
