Gyro Gearloose is an inventor who lives in Duckburg and works for Scrooge McDuck. Created by Carl Barks in 1952, he first appeared in Walt Disney's Comics and Stories #140 in the story "Gladstone's Terrible Secret". Ever since then he had a prominent role in the Duck Universe, including appearing regularly on DuckTales. He invented lots of inventions but his most famous invention are Little Helper and the Gizmosuit.
On DuckTales, Gyro was voiced by Hal Smith, who passed away in 1994. He has since been voiced by Corey Burton (in the video game Donald Duck: Goin' Quackers!) and Chris Edgerly (in DuckTales Remastered).
Gyro's collection of inventions includes the aforementioned Little Helper, the Millennium Shortcut, a time machine through which Bubba joined the McDuck household, the Gizmosuit, which turns Fenton Crackshell into Gizmoduck, and the robots Armstrong, GICU-2, and Robotica.
- Gyro and Little Helper do not appear in "Campaign Carnage, Part 3", but Doofus Drake and a regular lamp are drawn to be mistaken for them by the audience only for the duration of one page.
- Gyro and Little Helper made their animated debut in the Sport Goofy Soccermania special, which was the inspiration for DuckTales.
