A high-spirited young girl who has humorous misadventures with her neighborhood friends, she first appeared in Pep Comics #62 (July 1947).

Jinx was normally depicted as a lovable but mischievous young girl, engaged in a comical battle of wills with her long-suffering father.

Like most of Archie Comics' strips of the period, Jinx offered insights into family relationships and children's perceptions of the adult world.

Jinx was the daughter of Hap and Merry Holliday, earning her unusual nickname by virtue of being born on Halloween.

[4][5] In Jughead the Hunger vs Vampironica, an alternate version of Jinx reveals her real father to be Satan.
