This is a list of characters that appear in the Halloweentown film series.
Main Aggie Cromwell Splendora Agatha "Aggie" Cromwell (portrayed by Debbie Reynolds) is the mother of Gwen and grandmother of Marnie, Dylan, and Sophie. She is the daughter of Merlin's cousin Marvin. It is unknown if Cromwell was her maiden name, or if she is widowed, as she is referred to by others as Mrs. Cromwell in Halloweentown High. She is a witch and resides in Halloweentown until Gwen offers to let her move to the human world and live with them at the end of the first film. She agrees but is having a hard time not using her magic. In the first two films, she carries a bottomless carpetbag that magically strolls along next to her as she walks. The carpet bag is very faithful to her as well as being slightly cowardly, as in the first film it is scared to jump off a flying bus, but does so when she pretends to leave without it. In Halloweentown High, she tries to fit in by taking various teaching jobs at Marnie and Dylan's high school and falls for the principal. She has a new bag that follows her around, this one resembling an alligator without a head that loves to eat. In Return to Halloweentown, it is revealed that during the dark times, Splendora Agatha Cromwell was the Princess of Halloweentown, who possessed the Gift, an ancient power. It was a necklace that had the power to give the wearer complete control over any person, but it could only be worn by a Cromwell witch or warlock. An evil battalion of dark warlocks and witches known as the Dominion sought the Gift and wanted Splendora to use it to dominate Halloweentown. Wanting to live like a regular witch, Splendora placed the Gift in a locked box and buried it under the ruins of Cromwell Castle, where Witch University currently sits. It is said that only her heir could unleash the Gift that is stored inside and use the power within it.
Gwen Piper Gwendolyn "Gwen" Piper (née Cromwell) (portrayed by Judith Hoag) is the daughter of Aggie. She is the mother of Marnie, Dylan and Sophie Piper. She was born as a witch in Halloweentown. When she was young, she dated Kalabar, and she also went on a date with the bogeyman. She gave up her magical heritage for William Piper (a mortal) and married him. Even after her husband was deceased, she continues to live in the mortal world, believing that it is better to be "normal" and hates Halloween. Since Halloweentown Gwen uses her magic more freely and it continues to grow with each film. In Halloweentown, she keeps Halloweentown a secret from her children and would prefer to raise them as a mortal, not allowing anything that has to do with magic or Halloween be mentioned in the house. Dylan agrees with her, but Marnie and Sophie do not like that. Gwen would often fight with her mother on the subject of whether or not she should allow her children to follow their family's tradition, especially Marnie, who is about to lose her powers forever after her 13th Halloween. At the end of the first film, she offers to let Aggie come live with them and agrees to have Marnie do her witch training. Although Gwen accepts her child's urge to connect more with the magical heritage, she continues to encourage Marnie to not let all that magic go to her head, though Gwen eventually begins to accept magic more and more through each film. In Halloweentown II: Kalabar's Revenge, Gwen meets a handsome single father named Alex but does not know that he is actually a golem created to lure her into a trap. He takes her to a Halloween party, where the warlock Kal turns her and everyone at the party into monsters. By combining their magic, her family manages to reverse the spell. In Halloweentown High, she helps Marnie joggle nine teenage kids of different mythical heritage. When they discover that someone is trying to steal their magic by failing Marnie's project, Gwen teleports herself to Halloweentown to find proof for the Halloweentown Council. In the end, Gwen rescues Cassie from her prison and returns to the mortal world in time to help stop the plot. In Return to Halloweentown, her children flew off for college and witch training, and she became a real estate agent and used magic to make the houses look better. When Dylan gets turned into a dog, Marnie calls for her help. She, Marnie, and Dylan combine their magic and "destroy" the Gift together.
Marnie Piper Marnie Piper (also referred to as "Marnie Cromwell") (portrayed by Kimberly J. Brown in the first three films and Sara Paxton in the fourth film) is the oldest daughter of Gwen and William Piper, the granddaughter of Aggie, and the older sister of Dylan and Sophie. She is the main protagonist of the series, a young witch who has always loved the holiday of Halloween. Marnie is 13 years old in the first film, about 15 years old in the second, about 17 years old in the third and 18 years old in the fourth film. She is a pretty and headstrong individual, especially when it comes to magic. Like her grandmother and her sister, she has a sixth sense or precognition power as well as being an expert broomstick flyer. She is the character who uses magic as much as she can but also cares about it and tries very much to save Halloweentown and her magic. In Halloweentown, Marnie discovers for the first time about her witch heritage and becomes excited to start her training to be a witch. In Halloweentown II: Kalabar's Revenge, Marnie and her family combine their magic and create a portal that can be opened at any time around the year to stop a warlock from taking over the worlds. In Halloweentown High, Marnie bets on her family magic to persuade the Halloweentown Council to reunite the worlds of Halloweentown and the mortal world. In Return to Halloweentown, Marnie attends Witch University in Halloweentown and discovers a great secret about her family. She becomes Queen regnant of Halloweentown for one night, but uses the chance to apparently destroy the gift with the help of Gwen, Dylan and her genie friend, Aneesa, but only passes it on to Dylan, the one person she trusts not to abuse its power.
Dylan Piper Dylan Piper (portrayed by Joey Zimmerman) is the middle child and the only son of Gwen and William Piper, the grandson of Aggie, the younger brother of Marnie and the older brother of Sophie. Dylan is somewhat of a book nerd as he likes to study more than anything. He strongly dislikes Halloween and everything that goes with magic. Dylan is sarcastic and frequently teases his sisters, especially Marnie. He is the only warlock in the family, but doesn't like to use magic but will use it sparingly to help his family and study. In Halloweentown, Dylan is about 12 years old and remains skeptical about the existence of magic and the supernatural. His hands start to glow at the end of the film while being mad at Kalabar, indicating he has powers, which he uses to help in defeating Kalabar. In Halloweentown II: Kalabar's Revenge, Dylan tries to reach out to girls, but only ends up getting ditched and only uses his powers twice to help fix the worlds, first using them with his family and Luke to create a new permanent portal between the worlds and then – reluctantly, with the prodding of Luke – to break the spell on Benny. In Halloweentown High, Dylan does not use his powers at all and falls for a girl before finding out she was a pink troll. Though he does not use magic at all in this film, he states that he has tried to apologize to Natalie using magic to speed-up the speaking process. In Return to Halloweentown, Dylan attends Witch University with his sister and confesses that he used his powers to study rapidly in high school, which is the reason to why he skipped a grade and can attend college with his sister. He also falls for the evil Sinister sisters but they use him to get the gift - his family heirloom, so they can try to take over Halloweentown. Later, he becomes the wielder of the gift but decides to hide it in a book. He ends up using magic a few times in this film; he speed-reads to get the information on Splendora, admits to using it in high school, and uses it to help "destroy" the gift as it takes three Cromwells to do and only he, Gwen and Marnie were around. This is the most times he uses his powers in the films.
Luke Luke (portrayed by Phillip Van Dyke) is the laid-back friend of Marnie's who resides in Halloweentown. He is a goblin but is changed to human form by Kalabar. In the end, he loses his human form after helping Marnie defeat Kalabar. He helps create the permanent portal between the worlds and helps Marnie learn how to reverse the Grey Spell but is not seen or mentioned again after the second film. In the first two films, he has a crush on Marnie.
Sophie Piper Sophie Piper (portrayed by Emily Roeske) is the youngest daughter of Gwen and William Piper, the granddaughter of Aggie, and the younger sister of Marnie and Dylan. Like Marnie, she is also a witch. She can cast simple spells that she learns from her sister and grandmother. Unlike her older sister Marnie, the more advanced witch, Sophie appears to have a stronger hold on her precognitive powers. She can sense the presence of "bad things" to which she would always reply "Somebody's coming". She has a gift for remembering spells, something that Marnie continues to have trouble with, and is also resilient and quick at problem-solving. Sophie, like her sister and grandmother, has shown efficiency in conjuring. Along with her precognitive abilities, it appears that Sophie is telekinetic. In Halloweentown, Sophie is about 7 years old and can control her powers better than her sister can, as her grandmother states it only takes will and imagination for the magic to work. In Halloweentown II: Kalabar's Revenge, Sophie can sense Kal's presence, which her grandmother, mother, sister and brother cannot (although Gwen later can and Dylan indicates he senses something is wrong), but has a hard time controlling her flying abilities because Aggie had not taught her how to fly yet. In Halloweentown High, Sophie appears briefly and does not do magic at all. Sophie does not appear in Return to Halloweentown, but it is mentioned that she has started her witches training under her grandmother, Aggie.
Gort Gort (portrayed by Blu Mankuma) is an ogre that collects junk in his house because everything that gets lost in other places (mortal or Halloweentown) ends up in his house. He hates cleaning and everyone he encounters. In the second film, Kalabar's son Kal casts the Grey Spell on the whole town, turning them into the boring versions of humans, and Gort becomes an opposite version of his true self.
Phil Flanagan Principal Phil Flanagan (portrayed by Clifton Davis) is the principal of Marnie's school. He is a descendant of an army known as the Knights of the Iron Dagger. He originally helped Edgar Dalloway get the Cromwell's magic, but abandoned that job after he fell for Aggie Cromwell. Phil also admitted that he could not fit his finger into the ring that was associated with the Knights of the Iron Dagger.
Cody Trainer Cody Trainer (portrayed by Finn Wittrock) is Marnie's love interest in the third film. He constantly tries to ask Marnie out but never gets the chance to succeed as she is always distracted. He finds out her secret after Gwen knocks him out thinking he is an enemy and Marnie takes him out on a broom ride. At first, he is a little freaked out but learns to accept it and gets everyone else to accept it in the end. He and Marnie apparently start dating in the end but he is not seen or mentioned again after the third film.
