Powers and Abilities


Friends & Family

Splendora Agatha "Aggie" Cromwell

Splendora Agatha Cromwell is Marnie's maternal grandmother. They seem to very close and as a result, Marnie greatly respects and admires Aggie and looks forward to her visits very much. Marnie comments in the first movie that her grandmother is the only one who understands her fascination with strange things. Aggie wanted to train Marnie as a witch ever since she was born, but Gwen refused, delaying Marnie's training for thirteen years. After the first movie, Aggie does not just train Marnie, she moves right into the Piper home.

Gwen Piper

Gwen Piper is Marnie's mother. She is very protective of her children, much to Marnie's annoyance. Afraid that something about Halloween would trigger their powers or make them discover the world of Halloweentown, she did not allow them to go out during the holiday. As Marnie is fascinated by everything connected to Halloween, the two don't get along very well in the first movie. Marnie is quick to argue and complain about her mother being unfair, but when her mother is attacked by the shadow being she is clearly upset. By the end, Gwen is impressed with Marnie's courage and ability to face a powerful warlock and agrees to train her as a witch.

William Piper

William Piper is Marnie's father. He is human, making Marnie and her siblings half human, half witch/warlock. He died some time before the first movie. Little is known about their relationship, but she seems to love him very much.

Dylan Piper

Dylan Piper is Marnie's younger brother. In the first movie, scientifically-minded Dylan takes pride on being the only "normal" person in their family and for the majority of the movie tries to convince himself that Halloweentown is just a very strange dream. This mindset is the polar opposite of his older sister's, causing them to bicker often, as any brother and sister do. Despite the occasional friction, they do truly love one another. When Dylan shows signs of being a warlock, Marnie is proud of him. They attend high school and college together in the later movies.

Sophie Piper

Sophie Piper is Marnie's younger sister. She seems to look up to her big sister a lot, even though she appears to be a better witch than Marnie, at least in the first movie. They are very close and help each other often. When Sophie is about to cry in the first movie, Marnie comforts her.


A genie who is Marnie's roommate and quickly becomes Marnie's best friend in college, Aneesa helps Marnie to defeat the evil plaguing the school.


Cindy is a friend of Marnie's in Halloweentown II. Not much is known about their friendship, but they do seem to joke with each other and be close friends.


Cassie is a witch from Halloweentown and is good friends with Marnie. She is a part of the exchange student program between Marnie's high school and Halloweentown. It is unknown whether she went to the college with Marnie, Dylan, and Ethan.

Two Unknown Friends

At the beginning of the first movie, Marnie is trying to convince her mother to let her go to a Halloween party. These two girls appear to be Marnie's best friends, and they also try to convince Gwen to let her go, remarking that Marnie is very interested in all things Halloween. One is dressed as a clown and the other is dressed as a witch. Ultimately failing to convince Gwen to let her daughter go, they offer to bring back candy back for Marnie. Neither is ever seen again after the first movie.



Luke is Marnie's love interest in the first two movies. In the first movie, he agreed to work for the shadow being in exchange for being made handsome. At first, she thinks of him as a no-good punk who lured her grandmother into a trap, but he explains that he didn't think that the shadow being, would harm Aggie and genuinely wishes to make up for his part in luring her to it, coming up with a plan that helps Marnie defeat the shadow being for good. Realizing that Luke is truly a good guy, Marnie warms up to him. She kisses is cheek in the first movie. He isn't seen after the second movie and it's unknown what happened to their friendship.


Marnie has a big crush on a guy named Kal. He seems to return her affections. Kal and Marnie were going to go on a date to the Halloween dance, which was really a set up by Kal to turn the mortals, and Marnie's mother, Gwynn into horrible creatures, Marnie discovered his plans when she and Aggie went to Halloweentown. This resulted in Kal becoming Marnie's enemy


A human boy who likes Marnie right from the start, he becomes Marnie's boyfriend over the course of Halloweentown High. Apparently the relationship didn't last long because he is never seen again after the third movie.

Ethan Dalloway

Ethan, Edgar Dalloway's son, is a warlock who possibly has an interest in Marnie in the third movie. He manages to become Marnie's boyfriend in Return to Halloweentown. The movie ends with the two of them dating.
