Editing Gyro Gearloose (section)

==Appearances in other media==
Gyro made his first animated appearance in a 1980s full-length movie, the ''[[Sport Goofy in Soccermania]]'' television special, with only one line of dialogue, voiced by [[Will Ryan]]: "Scrooge parting with a million dollars?" In the subsequent 1987 [[List of animated television series|animated series]] ''[[DuckTales (1987 TV series)|DuckTales]]'', Gyro became a regular character, with [[Hal Smith (actor)|Hal Smith]] supplying his voice while [[Barry Gordon]] records it in several episodes. Among Gyro's noteworthy inventions in the series was the creation of the [[Fenton Crackshell|GizmoDuck]] suit, intended to be worn by a [[security guard]] for Scrooge McDuck's [[Money Bin]]. Although Gyro's shop and house are on the south side of Duckburg, he was born on the north side; a sign marks his birthplace and mentions one of his inventions: topless hats.<ref name="June_71">Walt Disney "Golden Key" Comic Digest # 29 June 1971</ref>

In high school, young Gyro was a [[baseball]] [[pitcher]] with his "madball" pitch — actually only a straight-ball pitch. When Gyro is forced to pitch for the Northside, pitting an "unhittable" baseball against another of his inventions, an "unmissable" [[baseball bat]] made for the Southside team, the result is total chaos.<ref name="June_71"/>

Gyro is a classic example of an eccentric genius. Once he persuaded the citizens of Duckburg to rebuild their metropolis into a climate-controlled "City of the Future". Unfortunately for Gyro, his idea worked too well. Donald Duck worked only 1 hour a day and spent 23 hours sleeping, which left him more grouchy than normal, while Uncle Scrooge's robot made him so much money that it filled up his money bin to the point where he could not even burrow into it. The final straw came when Gyro's Robot Helper makes a robot to replace Gyro as an inventor. Realizing Duckburg is not ready for the future, Gyro returns the city back to its old self.<ref>Walt Disney "Golden Key" Comic Digest # 21 April 1970</ref>

Contrary to his entry in [[Don Markstein's Toonopedia]], Gyro never appeared on ''[[House of Mouse]]''. Gyro, in his usual role as an inventor, is replaced with [[Ludwig Von Drake]] in ''House of Mouse'' and many other cartoons.

In the [[Toontown Online|Toontown]] universe, Gyro created a robot that, when Scrooge accidentally wired it incorrectly, made the Cogs, the main [[antagonist]]s of the game. They were grim businessmen-like robots who could not take a joke. So, to take care of the infestation, the Toons (the main [[protagonists]] of the game) destroyed them with gags such as squirting seltzer water and throwing pies at them.

A reimagined Gyro appears in the [[DuckTales (2017 TV series)|2017 reboot of ''DuckTales'']] (voiced by [[Jim Rash]]), in which he maintains a lab below Scrooge's Money Bin. This Gyro merges characteristics of his harsher, early comic book self with those of his original ''DuckTales'' counterpart along with adlibbing by Rash; the result being an eccentric who struggles with social graces and has a short temper, yet still retains a good nature and makes efforts to stop his inventions from harming people. He also has a track record of inventions gaining sentience and becoming evil, though he argues that some of them are merely misunderstood (a trait that the show creators have also attributed to Gyro himself). In his debut episode, "The Great Dime Chase!", he unveils Little Bulb (this show's version of Little Helper), who goes out of control under Louie's supervision (though Gyro manages to fix the problem by replacing his invention's head with a lower-watt bulb). He later begins brainstorming the creation of the [[Gizmoduck]] suit under the codename "Project Blatherskite". In season one's subsequent episodes, he took on [[Fenton Crackshell|Fenton Crackshell-Cabrera]] as an intern, clashed with Scrooge's rival Mark Beaks, and forced [[Donald Duck]] to swallow a voice modulator. In the season 2 premiere, he uses a modified shrink ray invention to communicate with a microscopic civilizations in the McDuck household, only to be taken hostage when he attempted to become their god-king. Later in season 2, his oxy-chew gum (used by [[Della Duck|Della]] and Donald Duck to survive on the moon), Time Teaser (used by Flintheart Glomgold in a scheme against Scrooge McDuck), and Time Tub (used by Gyro himself to travel back to the Old West and by Louie as part of a get-rich-quick scheme) make appearances. In the season 2 finale, he developed a clone spray that he used on himself and produced a small army of Little Bulbs with walkie-talkie functions. In season three, Gyro's past is explored further. Decades prior to the series, he worked as an optimistic young intern under roboticist, Dr. Akita. Gyro built a child-like defense drone named 2-BO and treated him like a real boy, but Akita tampered with his programming before using him to terrorize the city of [[Tokyo]]lk. Having lost his creation, Gyro became embittered and repressed his memories of the android. When Huey brought 2-BO, now B.O.Y.D., to him to be fixed, Gyro was forced to return to Tokyolk and confront his past as well as Akita. Once he learned what happened and defeated his former mentor, Gyro reconciled with B.O.Y.D.
