"Rightful Owners" is a four-part comic book story arc featured in the first four issues of Boom! Studios' short-lived DuckTales comic book, written by Warren Spector. Although advertisements and solicitations for the comic stated that Miquel Pujol would be illustrating the story, he had actually declined on drawing the comic; thusly, it was instead drawn by Leonel Castellani, Jose Massaroli, and Magic Eye Studios.
When Scrooge has an exhibition at the Duckburg Museum, showing off all the treasures he has acquired in his adventures, Webby comes to the conclusion that he should return all the items in his collection to their "rightful" original owners. Scrooge balks at the idea until John D. Rockerduck announces that he's doing the same thing with his treasures, and it becomes a competition between them.
- This is John D. Rockerduck's first and only appearance in DuckTales media (unless one also counts his and Flintheart Glomgold's silhouetted cameo in Darkwing Duck #8).
- The San Diego Comic-Con exclusive cover for issue #1 is a spoof of the cover to the Super Mario Bros. game for the Nintendo Entertainment System.
- The "B" cover to issue #3 is an homage to the cover of Gladstone Comic Album #15: Donald and Gladstone.
- The "B" cover to issue #4 is an homage to the poster for Indiana Jones and the Last Crusade.
