Mona Parker ("
Mona the Vampire") (voiced by
Emma Taylor-Isherwood) – A young girl with a vivid
imagination and a naive personality who imagines herself as a
vampire heroine coming out to save the day. She believes the town she lives in is overrun with supernatural monsters, and she plans to stop them all and save the town on a daily basis. Although Mona's active imagination can cause trouble at times, her imagination has more often than not proven to be helpful. •
Fang – Mona's pet cat, he is a feline sidekick who always follows Mona everywhere. Fang is her accomplice in the nether realms of her imagination. When going with Mona while in her vampire costume, he has fake bat wings tied to his back. •
Charles "Charley" Bones ("
Zapman") (voiced by
Justin Bradley in seasons 1–3; Evan Smirnow in season 4) – One of Mona's best friends, he is an intelligent but also timid bespectacled boy in real life. His alter-ego is Zapman, who wears a green alien costume and is armed with a Zapp-A-Rama gun, which really is a water pistol, though he can be seen holding another kind of toy gun. Charley's nemesis is the local school bully George. •
Lily Duncan ("
Princess Giant") (voiced by
Carrie Finlay) – One of Mona's best friends. She has a timid and slightly paranoid personality at times, but she is still helpful to the team. Her alter-ego is Princess Giant, who wears a long blond wig adorned with a crown and holds a stuffed toy cat. •
Mr. and Mrs. Parker (voiced by Marcel Jeannin and Carole Jeghers) – Mona's parents. Mrs. Parker is shown to be the stricter of the two, while Mr. Parker is more light-hearted and somewhat clumsy, as he is more likely to believe what Mona thinks in her imagination. •
Angela Smith (voiced by Tia Caroleo) – Mona's snobby rival, a rich girl who frequently displays her wealth to her classmates. She also regularly enlists George in her schemes to cause problems for Mona. Her parents won the lottery, explaining her unconditional wealth and her resulting spoiledness.
