Ghoulia is depicted as intelligent, sophisticated, timid, stressed out, and shy.
For each of these functions, the practical considerations, the most successful methods and their future development are discussed.
She is also stressed out at times such as when Frankie said hi to Deuce which Cleo claimed is cheating on her.
Ghoulia gets so stressed out that she slaps her forehead in "New Ghoul @ School" and sighs in stress when her glasses break after Cleo's banshee scream breaks them in "Neferamore".
As an expert on comic book culture, Ghoulia also writes for the Gory Gazette and is the paper's default Nekrocon reporter.
In the English version of the cartoon series, Ghoulia's vocal effects are provided by Audu Paden.
