Newton Gearloose

Newton Gearloose first appeared in the Gyro Gearloose story in 1960 by Vic Lockman in Walt Disney's Comics and Stories #308 as Gyro's nephew in a story titled 'Ting-A-Ling Trouble'. He subsequently appeared in Walt Disney's Comics and Stories #309, as well as in Huey Dewey and Louie's Junior Woodchucks #1, 2, 49, and 50. Newton was a fan of his uncle's work, and wanted to be an inventor like him when he grew up. Newton was also a Junior Woodchuck, as well as a friend of Huey, Dewey and Louie. Newton also went by the nickname "Giggy."

After the early 1970s, Newton ceased appearing in new North American Disney comics. He continued to be used in some Italian and Danish-produced Disney comics into the late 1990s.

There was a similar character in the DuckTales episode "Superdoo", like Newton he was also in the Junior Woodchucks. Though his name is never spoken he does bear a physical resemblance to Newton Gearloose.
