Paperinik (also known as Phantomias, Duck Avenger, Superduck, PK, Fantomerik, Superdonald and Phantom Duck) is a comic book superhero, Donald Duck's alter ego. Donald originally created his superheroic identity as a means of secretly seeking revenge against relatives such as Scrooge McDuck and Gladstone Gander, but soon found himself fighting other menaces. The character is an Italian invention and, as a pervasive feature where he appears, very much not in canon with stories that do not feature him.
