Mortimer Jibbet was the younger brother of boy cartoonist Scribbly Jibbet. Also known by nicknames "Dinky" and "Snoony", Mortimer was a general pain in his brother's side. Along with his neighbor Amelia "Sisty" Hunkel, Mortimer became one of the Cyclone Kids, sidekicks to the original Red Tornado (actually Amelia's mother, Abigail "Ma" Hunkel), and had various humorous adventures around their neighborhood.
Years later, Mortimer and Amelia put on their costumes again as members of Old Justice, a collection of former sidekicks from the 1940s who tried to turn public opinion against new young adult superheroes like Young Justice. Later, Mortimer's niece Maxine took on the superhero identity of Cyclone in his and Sisty's honor as a member of the Justice Society.
As one of the Cyclone Kids, Mortimer had no powers or special abilities, and was not even a particularly skilled fighter.
