Who Is Gizmoduck? is a cartoon written by Chris Magalhaes (along with DuckTales 2017's normal team of writers) and directed by Tanner Johnson. It features Huey, Dewey and Louie Duck, Scrooge McDuck, Donald Duck, Mark Beaks, Fenton Crackshell-Cabrera (and his alter-ego Gizmoduck), the Beagle Boys, Flintheart Glomgold, Roxanne Featherly, the Headless Man-Horse, and, in her debut, M'ma Crackshell-Cabrera.
After more and more heroics, Fenton Crackshell-Cabrera's robotic identity Gizmoduck has become famous and Huey Duck's idol. The "famous" part catches the attention of hype-maniac Mark Beaks, who attempts a corporate (and, if possible, corporal) takeover of the Gizmoduck brand and suit.
