Half vampire, half fairy, totally unique!
Based on the series of books by Harriet Muncaster, Isadora Moon is a 2023 British animated series following the adventures of a half-fairy and half-vampire girl, originally premiering on the British channel Sky Kids. It premiered in the US on HBO Max (then known as Max) on January 2, 2025.A Spin-Off focusing on Emerald, which itself is based on the book of the same name, premiered on September 1, 2025 on Sky Kids. Another Spin-Off based on the books, this time starring Isadora's cousin Mirabelle, is currently undated.
This series provides examples of:
- Accents Aren't Hereditary: A mild example. Isadora shows no signs of her dad's Italo-Slavic-esque accent and instead solely uses her mum's London accent.
- Ageless Birthday Episode: In "Isadora Has a Birthday", Isadora's age is never specified.
- Chekhov's Gun: Mignonette's rainbow crown in "Rainbow Quest", which she says she is not sure what it does or how it will help her find the pot of gold at the end of a rainbow. Near the end of the episode, it turns out to be able to teleport the wearer if she and nearby people sing a happy song about the rainbow.
- Cheery Pink: Cordelia is always peppy and seems near-unable to get angrynote , and her clothes and hair are primarily pink with a touch of green (but falls short of being a Redhead in Green).
- Child of Two Worlds: Isadora and her baby sister Honeyblossom are half fairy and half vampire.
- Colorization: The books had a very characteristic black-white-pink colour palette, while the show is in full colour.
- Commander Contrarian: Ava from "The New Girl" denies that Isadora is a magical being to her face, despite evidence to the contrary. Rather than this being a case of Arbitrary Skepticism, it becomes clear that she's being deliberately obtuse to get on Isadora's nerves.
- Cool House: The Moons' house has numerous exterior wall colours, and castle-like balconies and other castle concepts, in the middle of an otherwise very standardised Suburbia that their house also rises more than 2 floors taller than all the other houses in.
- Cute Little Fangs: Sported by half vampire Isadora and her full vampire cousin Amma.
- Cute Monster Girl: Well, half-monster girl anyway. Isadora is fifty percent vampire, fifty percent fairy, and one hundred percent adorable.
- The Dandy: Batholomew takes great pride in his hair and looks, often panicking when he is not looking at his best.
- Didn't See That Coming:
- In "Fairy Lessons", Cordelia and Alvin rush out of her arboretum gasping for breath, with Cordelia saying that the Stinkweed Fragrance didn't work out. Alvin promptly points out that the name should have clued her in on it.
- In "Mignonette Moves In", a group of woodpeckers have moved in to a tree and keeps Mignonette awake for weeks due to them pecking holes in the tree constantly. The woodpeckers then move out again mere weeks after they moved in, because there were too many holes in the tree.
- Easily Overheard Conversation: In "Magic Pox", Isadora talks with Mirabelle on their video-chat Crystal Ball about how to fake looking ill so Isadora can skip a maths test. With Isadora speaking loudly (and with Mirabelle audible) and with Cordelia almost certainly less than 5m away, Cordelia catches on. When Isadora wakes up the day after, Cordelia smilingly gives intentionally dubious treatments, expecting Isadora to slip up, which indeed occurs.
- Everybody Hates Mathematics: In "Magic Pox", Isadora incorrectly believes that fairies and vampires cannot be good at maths, and is therefore scared of the next maths test. And although she is well into primary school age (Exactly which school year is ambiguous), she didn't learn that 3×2=6 until near the end of the episode.
- Fantastically Indifferent: Humans don't bat an eye at Isadora, her family or any other paranormal beings.
- Fantastic Racism: Nova, a Glow Sprite, grew up on her own planet thinking humans were awful beings who were inferior to Glow Sprites in every way, and is taken by surprise when she learns that Earth things are just as good as (and in some cases better than) Glow Sprite things, eventually going back to her home planet to spread the news.
- Granola Girl: Cordelia is constantly cheery and focuses a lot on gardening and flowers, including having flowers in her hair and with pink-green clothing to invoke flower-like themes.
- Guilt-Tripping: Zoe pulls this off on Isadora in "Sponge and Sprinkles" to win tickets for a TV show, and in "Fairy Vampire Kitten" to try to impress a relative of Zoe who frequently lies in order to brag to others. Isadora gets very uncomfortable about it on both occasions.
- I'm Not Hungry: Played with. In "The New Girl" it's explained that due to Isadora's fairy genetics all food tastes like cardboard when she's upset.
- Interspecies Romance: Cordelia (fairy) and Batholomew (vampire) are shown in several episodes as being a very loving couple.
- Living Toy: Isadora's stuffed toy Pink Rabbit, brought to life by her mother.
- A Lizard Named "Liz": Isadora's dad is named Batholomew (without an R), being a vampire and all.
- Loose Tooth Episode: "The Wobbly Fang" starts with Isadora having a loose baby fang. It comes out when she bites into an apple.
- Loud Sleeper Gag: Mignonette is shown in "Mignonette Moves In" as snoring very loudly and keeping Isadora awake, and on her first day at the Moons she sleeps (and snores) nonstop from mid-afternoon to a short while before breakfast hours the following morning.
- Magic Music: The song the characters sing throughout "Rainbow Quest" turns out to be this when combined with Mignonette's Chekhov's Gun, eventually teleporting them to the pot of gold at the end of the rainbow, making Mignonette able to pay her school enrollment fee.
- Magic Wand: Practically all fairies in the show have one. Isadora's wand skills are somewhat weaker than the older ones in her family, partially due to being a child, partially due to having a beginner's wand, and partially due to being a fairy-vampire hybrid.
- Micro Dieting: For the first breakfast Mignonette cooks for the Moons in "Mignonette Moves In", she cooked the food in "Small fairy"-sized portions, having not yet realised that the ones she was cooking for were significantly taller (Around 1-2 meters).
- Modest Royalty: The Moons live relatively normal lives despite the parents being a count and countess.
- New Friend Envy: The main plot of "Three's a Crowd" has Isadora fear this after Nova and Sashi click so well with each other that Isadora can't find a way to jump into their games.
- New Job as the Plot Demands: Mignonette tries out several jobs throughout the show, including tooth fairy, delivery fairy, studying to be a magic teacher, and crafting plant potions.
- The Night Owl:
- Zig-zagged for Batholomew in particular. He greatly prefers sleeping during the day (being a vampire and all), but is more or less okay with doing tasks during daytime without showing signs of being sleepy.
- Isadora attends human primary school despite in some episodes doing activities in the middle of the night.
- No Antagonist: While characters like Isadora's ghost friend Oscar and cousin Mirabelle occasionally cause mischief, there is no outright villain. Ava in "The New Girl" gets close, but becomes a Reformed Bully near the episode's end.
- Non-Human Humanoid Hybrid: Isadora is half vampire, half fairy.
- Obfuscating Stupidity: Cordelia does this at times to encourage Isadora to handle situations on her own:
- For most of "Zoe's Magical Moment", Cordelia seems to have a case of Parental Obliviousness as Isadora tries to distract her from realising that Zoe has magical powers and that Isadora (who lacks magic powers at that point) has problems figuring out how to fix it. Near the end of the episode, Cordelia asks Isadora with a clever smile how it was to give Zoe magic powers for a day, indicating Cordelia was well aware for at least a large chunk of the episode.
- In "Magic Pox", Cordelia initially seems to believe in Isadora's sickness, but the cures she recommend to Isadora (Icky porridge, cancelled birthday party, stay in bed) are harsh enough that older viewers would quickly realise that Cordelia almost certainly knew that Isadora was faking.
- Open-Minded Parent: Neither of Isadora's parents (Cordelia and Batholomew) mind which of them she decides to take after.
- Our Fairies Are Different: Isadora's family on her mother's side all dress in pink and green clothes and are obsessed with flowers; two other relatives are winter fairies who dress in light blue and white and are obsessed with ice and snow. There is also a much smaller fairy named Mignonette who is constantly trying out new jobs.
- Our Vampires Are Different: Vampires in this universe don't drink blood and sunlight does not affect them.
- Parental Obliviousness: Cordelia has a case of this in "The New Girl", insisting Isadora invite Ava to Isadora's birthday party, happily ignoring Isadora's pretty bad experiences with Ava at that point.
- Phoneaholic Teenager:
- Heavily averted, as no one in the show are ever shown using phones or computers despite it taking place in more or less contemporary times, and only sporadically do anyone watch TV either. They are however well aware of the biggest television celebrities in their town.
- Series 2 established the Moons as having a Crystal Ball in their hallway for video chats, similar to the role home phones had until the mid-2000's.
- Playing Sick: The premise of "Magic Pox". Isadora, considering herself unsalvageably bad at maths, uses a potion to fake an illness involving large coloured dots. As Isadora made little effort to hide her plans the evening before, Cordelia catches on (In part also since the dots looked unusual) and gives her intentionally dubious treatments such as icky porridge for breakfast, cancelling a party invitation that day, and telling Isadora to get lots of rest in her bed. Isadora eventually slips up when going out of the bedroom, and she and Cordelia agree that her treatment was sufficient to make up for the faking.
- Rouge Angles of Satin: The American subtitles on Max often misspell Batholomew as "Bartholomew", which misses out on the "Bat" pun in his official name.
- Same Language Dub: The show has 2 Swedish dubs, one for Sweden and one for Finland.
- Shout-Out: In "Sponge and Sprinkles", JJ declares he's going to win the cake baking competition by shouting "Winner, winner, dino dinner!"
- Slippy-Slidey Ice World: The winter fairies' land in "Isadora Moon's Winter Magic" has snow everywhere, aurora borealis, snowy mountains, and a large white castle.
- Stock Punishment: When the kids go on a field trip to a castle, Batholomew is put in a pillory and the kids throw wet sponges at him.
- Team Spirit: A fair few episodes end up being resolved through this, for instance in "Save the Tree", where they band together as a public campaign to prevent a tree from being chopped down.
- The Show of the Books: Some of the episodes are to some degree based on Muncaster's books. "Isadora Moon and the New Girl" became "The New Girl", "Isadora Moon and the Shooting Star" became "The Shooting Star", and various other cases.
- Smart People Speak the Queen's English: Since the British original voicing is used on Max in the United States, several characters come across as this, Cordelia in particular. Though the closed captions on Max in the United States retains Isadora calling Cordelia "Mum", the rest of the show uses American grammar on Max ("Flavor", "Color", e.g. in the episode "Fairy Lessons").
- Straying Baby: Honeyblossom has a habit of levitating out of her high chair and crawling on the ceiling.
- Student Debt Plot: In "Rainbow Quest", Mignonette can't afford entering studies for advanced magic, so she comes up with a plan to reach the end of a rainbow to find its pot of gold. Unaware that rainbows look as if they get further away when approaching them, she continues chasing them while Isadora and Zoe sing a song about it. Mignonette wears a rainbow crown for unclear reasons, which teleports them to the end of the rainbow and its gold when she joins them in singing.
- Take a Third Option: In "The Wobbly Fang" Isadora loses a baby fang and struggles to decide whether she wants to frame it like vampires do or put it under her pillow for the Tooth Fairy like a human child. In the end she decides to have it framed, but promises tooth fairy Mignonette that she can have the other one when it falls out.note
- Trauma Button: Having been bullied for being considered childish for bringing her plush toy to class at her previous school, Ava in "The New Girl" is very defensive against showing any signs of weakness, ending up bullying the entire class (and Isadora in particular) until her gig slips up, at which point Isadora's class more than happily joins her in playing with their plushies.
- Vampire Vords: Batholomew's accent resembles this, but is downplayed enough that he sounds more like something from the Super Mario Bros. games.
- Voluntary Shape Shifting: Vampires are capable of turning into other creatures, though Isadora, being a child, was initially unskilled at it and caused herself to Shape Shifter Mode Lock when she transformed into a kitten.
