fact, here Donald has never even been Paperinik and he gains his secret identity after being selected and hired by the AI U.N.O. as a "guardian of the galaxy" (Donald chooses "PK" as his name when the other Guardians ask for it and he makes it up quickly reading part of a code printed on his equipment). This last series was a decent commercial success but, though having most of the cast of writers and artists from the previous two issues, was poorly received because of the clear cut from PKNA and PK² in favour of shorter, lighter, simpler and often self-contained stories, but also because of the overall lower quality of stories and illustrations. Starting from Topolino #3058, PK received new stories resuming the PKNA continuity, beginning with PK - Might and Power: a series of four episodes written by Francesco Artibani and drawn by Lorenzo Pastrovicchio, in which the Raider and Odin Eidolon (Uno's future persona) persuade Donald after years to go back to his Duck Avenger identity, and prevent the Evronian empire from rising again. In May 2015 has been published the four-episode issue PK - The Banks of Time, which focuses on time paradoxes and marks the return of Lyla Lay; this venture is scripted by Alessandro Sisti, designed by Claudio Sciarrone and colored by Max Monteduro. These new issues, nicknamed by fans Paperinik New Era (shortened as PKNE) as they don't have a collective name, revolve around the same themes of the original magazine (albeit in a lighter manner, being now part of the Topolino comic book) evolving them from their original closing, bringing back old characters and introducing new ones, such as the ambiguous Keeper of the Omega Chamber (another AI designed by Ducklair) and Moldrock. In the US, the origin story of Paperinik premiered in a two-part issue under the title "The Diabolical Duck Avenger" in 2015. Other media In 2002, a video game loosely inspired by PKNA was released for PlayStation 2 and Nintendo GameCube, entitled PK: Out of the Shadows (sometimes called Donald Duck PK, or just PK). In the game, Donald Duck, guardian of the Ducklair Tower, is transported into the artificial intelligence secret area and tasked with saving the world from the Evronians. He is given special powers, and told that he has become a "platyrhynchos kineticus", an energized duck, or PK for short, stepping around his Paperinik roots.
