Context: "The Son of the Sun" is the first Scrooge McDuck comic by Don Rosa, first published in 1987.  It is a well-known comic book story that features Disney's Scrooge McDuck, Donald Duck, and Huey, Dewey, and Louie, most notable for establishing Don Rosa as a major talent in the Disney comic book industry, as well as fulfilling Rosa's childhood dream of becoming a writer and illustrator of stories featuring Scrooge McDuck. The following is an episode list for the Disney animated television series "DuckTales".  The series is based on the Scrooge McDuck character and the "Uncle Scrooge" comic books created by Carl Barks.  The series stars Scrooge, his grand nephews Huey, Dewey, and Louie and Webby Vanderquack, and several new characters created explicitly for the series.  While Huey, Dewey, and Louie originated in Donald Duck animated short subjects in the 1930s, their characterization on "DuckTales" approximated that of Barks' comics.  Although Donald Duck was a major player in the "Uncle Scrooge" comics, he only appeared as a guest star in a few "DuckTales" episodes. The Clan McDuck is a fictional Scottish clan of cartoon ducks from which Disney character Scrooge McDuck is descended.  Within the Donald Duck universe, the clan is related to the American Duck family through the marriage of Hortense McDuck and Quackmore Duck, Donald's parents. Flintheart Glomgold is a fictional character in Disney comic books, created by Carl Barks in 1956.  He is a South African white duck and the archenemy of Scrooge McDuck, usually portrayed as an ambitious, ruthless, and manipulative businessman who shares many of the same qualities as Scrooge—the drive for massive wealth, and the and creativity to obtain the same—but he lacks any of Scrooge's tendencies towards generosity and compassion.  In Don Rosa's "The Life and Times of Scrooge McDuck" he is said to be a Boer. Scrooge McDuck is a fictional character created in 1947 by Carl Barks during his time as a work-for-hire for The Walt Disney Company.  Scrooge is an elderly Scottish anthropomorphic Pekin duck with a yellow-orange bill, legs, and feet.  He typically wears a red or blue frock coat, top hat, pince-nez glasses, and spats.  He is portrayed in animations as speaking with a Scottish accent. Paperon Intelligence Agency (acronym: P.I.A.) is an ongoing storyline in the Italian Donald Duck pocket books.  In the storyline, Scrooge McDuck ("Paperon de' Paperoni") is the chief of an intelligence agency named after him, whose intention is the protection of his money.  Scrooge employs Donald Duck and Fethry Duck as secret agents to fight various enemies, such as the Beagle Boys and the mad scientist Zantaf.  Donald's codename is Qu-Qu 7 ("quasi qualificato", Italian for "almost qualified"; also a pun on "cucù-settete" or "bubù-settete", the Italian word for "peekaboo"), and Fethry's codename is Me-Se 12 ("a mezzo servizio", "in half service"; also a pun on "mese", "month", and the number of months in a year).  In contrast to the "DoubleDuck" storyline, "Paperon Intelligence Agency" is farcical, with Donald and Fethry bumbling up pretty much every mission Scrooge sends them on. North of the Yukon is a 24-page funny animal comic book adventure story featuring Scrooge McDuck and his nephews, Donald Duck and Huey, Dewey, & Louie.  It was written and drawn by Carl Barks.  This was his last story involving Scrooge's adventures in Alaska.  It was published in September 1965, and later reprinted in May 1993.  Gemstone Publishing later reprinted the story again in 2005 for a Donald Duck/Uncle Scrooge graphic novel with another story inspired by this one called "Somewhere in Nowhere".  The character of Barko was inspired by an actual sled dog named Balto, who participated in the 1925 serum run to Nome.  Barks had read an article about Balto in an issue of "National Geographic", and was inspired to create this character. The Donald Duck universe is a fictional shared universe which is the setting of stories involving Disney cartoon character Donald Duck, as well as Daisy Duck, Huey, Dewey, and Louie, Scrooge McDuck, and many other characters.  The world is a part of the Mickey Mouse universe, but is more detailed.  Life in the Donald Duck universe centers on the city of Duckburg, usually located in the fictional U.S. state of Calisota, analogous to Northern California.  The world also incorporates several other real and fictional locations, as well as historical figures and a fictional timeline, which is followed with varying degrees of consistency. This list of Donald Duck universe characters focuses on Disney cartoon characters who typically appear with Donald Duck and Scrooge McDuck, but are not related to them.  For relatives of Donald and Scrooge, see Duck family (Disney) or Clan McDuck.  For characters exclusive to the "DuckTales" franchise, see List of "DuckTales" characters. Uncle Scrooge (stylized as Uncle $crooge) is a comic book starring Scrooge McDuck ("the richest duck in the world"), his nephew Donald Duck, and grandnephews Huey, Dewey, and Louie, and revolving around their adventures in Duckburg and around the world.  It was first published in Four Color Comics #386 March 1952, as a spin-off of the popular "Donald Duck" series and is still presently ongoing.  It has been produced under the aegis of several different publishers, including Western Publishing (initially in association with Dell Comics and later under its own subsidiary, Gold Key Comics and its Whitman imprint), Gladstone Publishing, Disney Comics, Gemstone Publishing, Boom!  Studios, and IDW Publishing, and has undergone several hiatuses of varying length.  Despite this, it has maintained the same numbering scheme throughout its six decade history, with only IDW adding a secondary numbering that started at #1.
