The Duck Avenger in American comics (also known as Paperinik, Phantomias, Superduck, PK, Super Donald and Phantom Duck), is a comic book superhero who is 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, though dominant in stories in which he appears, is very much absent from all others not starring him.
