Hannah Marie

Hannah Marie is Jimmy's younger cousin. She is first seen dressed up as a Fairy Princess, then in the second film and book, she dressed up as a Fairy Queen. During the story throughout she meets and befriends many inhabitants of the Frightside, an alternate dimension that sustains itself on Halloween magic, even though she started out being terribly afraid of monsters. Out of all her monster friends, she's very close to Scary Godmother.

Personality
Hannah Marie started out as being a shy and sweet-natured little girl, though over the course of the series of books and films she turned into a much more assertive, brave, and admirable character. She's at the age where she has a fascination with cute things, the colour pink, clowns, dinosaurs, and notably fairies. Her enjoyment of these things doesn't diminish with her new love of Halloween after the events of the first film and book. Hannah Marie's very beloved by her Monster friends in the Frightside, and they like to help her out in anyway when they can. In the series, it's shown that she has a stable and loving family, her father often referring to her with the pet name "Pumpkin".

Appearance
Hannah Marie is a young Canadian girl, with short, curly brown hair, fair skin colour, and big brown eyes. She is often seen wearing pink clothes and a fairy princess crown over half her body length, though her casual outfit seen consisted of a pastel pink cardigan that appears to be missing buttons near the chest causing the edges to flare out, a black shirt with a red circle, a purple skirt and long tights. She also wears brown boots.

Scary Godmother, Halloween Spooktakular
Hannah Marie is first seen staring out of her living room window anxiously surrounded by interior Halloween decorations exhibiting a fear of the dark, worried that her cousin Jimmy hasn't shown up with his friends yet, as it was the first night she was to go trick or treating, not with her parents. Her parents assure her everything will be alright and then they give her a pink flashlight telling her monsters can't stand them, and soon after Jimmy and his friends arrive to take her trick or treating. But before heading off, her mother tells her not to worry, cause scary godmother will protect her, before telling Jimmy to have her back by 8:00. Struggling to keep up due to her small body, Hannah Marie and friends eventually begin trick or treating down the neighbourhood. Jimmy, being a miscreant, not having to be enjoyed the idea of taking Hannah along from the start, he comes up with the idea of terrifying her so much that she would want to go home on her own. Leading Hannah far from the original route, they stop at an old house for sale, calling it the "spook house". After some talking, they get Hannah to go into the spooky house and abandon her, only for her starting to cry, and then her Scary Godmother arrives and comforts her, which she introduces her to her friends, Skully Pettibone, and Bug-a-boo (In the film they introduce a werewolf and the vampires). After seeing how the older kids are afraid of being punished for their mean behaviour, the monsters and Hannah each conspire to scare the pants out of the older kids as payback. Once the plan's played out, Hannah "saves" the older kids and then they make their way out of the house. In grateful appreciation of Hannah's theatrics, they load her up with candy and the first book ends with Hannah irresponsibly leaving her dog to consume fatal amounts of chocolate.

Scary Godmother, The Revenge of Jimmy
Hannah Marie is seen next to her revived dog having been changed by her past experience in the spooky house, earning both confidence and initiative in how she manages her day-to-day life from putting up decorations to, at every turn, foiling Jimmy's plans to ruin Halloween thus further angering him and causing him to transform into something resembling a stereotypical Orc, Troll, or Goblin, possibly a combination of the three. In the end, it is seen that she is able to turn things around for Jimmy and solve his fears, and save Halloween with the power of friendship and fairy dust.

Relationships
Scary Godmother: Both of them have a close relationship after meeting and becoming friends, so much so that Hannah is lent a key which allows her to visit the flipside anytime.

Jimmy: They are cousins, and Hannah seems to believe and care for Jimmy, despite Jimmy being crabby and sour.

Orson: Both Orson and Hannah show that they have a crush on each other in both films.

Bug-a-boo: She's a great friend with Bug-a-boo, having to overcome her fear of him and she likes to hug him.
