of Glittering Goldie (Scrooge's prospective love interest in the Klondike), and Kildare Coot (Sgrizzo Papero in Italian), an eccentric nephew of Grandma Duck. Paperinik (Duck Avenger) Paperinik (), also known as PK (Italy, USA video game), Duck Avenger (USA), Superduck (UK),) is a comic book-costumed vigilante, Donald Duck's alter ego. Donald originally created Paperinik as a dark avenger alter-identity to secretly seek revenge upon relatives such as Scrooge McDuck and Gladstone Gander, but he soon found himself fighting other menaces as a superhero. The character is an Italian invention and, though dominant in stories in which he appears, is very much absent from all others not starring him. The Italian creators (editor-in-chief Elisa Penna, writer Guido Martina, and artist Giovan Battista Carpi) introduced Paperinik in the two-part, 60-page story "Paperinik il diabolico vendicatore" ("Paperinik the diabolical avenger") published in Italy in Topolino #706–707, on June 8 and June 15, 1969. The name "Paperinik" was initially meant to reference the Italian comic book antihero Diabolik, to which Paperinik's original depictions wear similarities. The debut story featured Donald receiving the ownership papers of Villa Rosa, an abandoned villa outside of Duckburg whose owner had disappeared decades ago. Donald soon finds that the ownership papers were actually intended for his cousin Gladstone, but he is content not to correct the mistake. Visiting the villa with his nephews, he discovers the diary and an abandoned suit of Fantomius (Fantomallard), who was known as a notorious gentleman burglar and sometime vigilante active long ago. Donald learns Fantomius's methods of maintaining a secret identity by acting as a harmless and rather incompetent gentleman during the day and during the night as a vindicator, taking revenge for his grievances against society. In the early stories, Paperinik was not actually a superhero, but an anti-hero vindicator inspired by Diabolik and Fantômas. The writers toned this aspect down later and turned him into a Batman-style heroic avenger instead, and he started targeting the criminal population of Duckburg, in particular the Beagle Boys. This still remains his main mission today, although he occasionally faces higher profile adversaries and finds missions which require him to travel away from Duckburg. Paperinik's most important ally in his heroic identity is the inventor Gyro Gearloose, who fabricates most of his special equipment, but (in some stories) without knowing his identity. To be able to equip and support Paperinik without risk of accidentally disclosing his
