In the original series, Fred wears an orange ascot tie with a blue shirt and white sweater.

In the 2002 series What's New, Scooby-Doo?, Fred's outfit was given an update, with his orange ascot being replaced with a blue stripe.

Although generally a very nice guy, Fred can be bossy at times forcing Shaggy and Scooby to take part in nabbing the villain despite their fears and/or better judgment.

In A Pup Named Scooby-Doo, Fred was depicted as being somewhat less intelligent and often believed crazy conspiracy theories and legends such as Bigfoot and mole people and read the magazine The National Exaggerator.

In What's New, Scooby-Doo?, the teenage version of Fred is shown to have many interests such as traps, martial arts, wrestling, and weightlifting.

Fred Jones was inspired by the titular character of the late 1950s/early 1960s American sitcom The Many Loves of Dobie Gillis, as played by Dwayne Hickman.

His biological parents Brad Chiles and Judy Reeves later returned, but Fred continued to use the last name of Jones.
