## Premise and characters
Isadora Moon is the daughter of Countess Cordelia Moon, a fairy, and Count Bartholomew Moon, a vampire, making her "a bit of both". The series follows her magical adventures and misadventures at home and at a human school, where her classmates include human children[7](https://www.hulu.com/series/isadora-moon-9c04f3ca-daec-44ce-b658-2dc115fa3435) • [23](https://press.wbd.com/na/media-release/hbo-max/isadora-moon-flies-us-max-animated-series-launches-january-2). She carries a beginner's fairy wand and is still developing her vampire skills, with her loyal sidekick Pink Rabbit, a toy magicked to life by her mother, at her side[2](https://www.aboutpremiumcontent.com/?programs=isadora-moon) • [8](https://harrietmuncaster.co.uk/wp-content/uploads/2018/02/Isadora-Moon-Story-Dice.pdf). Her cousin Mirabelle, a witch, is a recurring character[8](https://harrietmuncaster.co.uk/wp-content/uploads/2018/02/Isadora-Moon-Story-Dice.pdf).
Episodes center on everyday childhood issues treated with a magical twist: losing a first fang and choosing between the fairy Tooth Fairy and the vampire tradition of framing it, a school trip to a haunted castle where Isadora befriends a lonely ghost named Oscar, a broken wand that turns her father green, and a slime craze in the playground that her own magic makes worse[9](https://www.rottentomatoes.com/tv/isadora_moon/s01). Each episode closes on a lesson about responsibility, honesty, friendship, or admitting mistakes[10](https://contraste.info/tv/isadora-moon/).
## Themes
The central theme is self-acceptance: Isadora need not choose between being a fairy or a vampire, and her difference is presented as what makes her special[11](https://actu.m6.fr/jeunesse/isadora-moon-le-dessin-anime-parfait-pour-prolonger-les-vacances-de-printemps-sur-m6). Showrunner Deborah Thorpe described the series as "a celebration of individuality and self-acceptance", and Muncaster framed its message as "there is one thing you can do better than anyone else in the world: be yourself"[1](https://press.wbd.com/us/ca/media-release/isadora-moon-flies-us-max-animated-series-launches-january-2?language_content_entity=en).
Reviewers have noted the show's handling of diversity. Common Sense Media rates it for age 5 and up, praising its positive role models and noting that Isadora's school friends represent various ethnicities and body types, with one character who has a prosthetic leg and loves soccer; the site records no violence and only very few mildly scary moments, such as magic going wrong and a blob of slime coming to life[6](https://www.commonsensemedia.org/tv-reviews/isadora-moon).
## Production and release
Kelebek Media, the company founded by Deborah Thorpe, optioned the rights to the books in 2020, in a deal brokered by Jodie Hodges at United Agents, and developed the property as a 2D animated series[12](https://senalnews.com/en/content/kelebek-media-develops-isadora-moon-series-based-on-global-hit-books). Animation was supplied by JAM Media, with post-production services by The Ark[13](https://www.imdb.com/title/tt30332037/companycredits/).
Series one premiered on Sky Kids in the United Kingdom on 17 November 2023 and ran through March 2024; season two aired 24 episodes between September 2024 and May 2025[3](https://isadora-moon.fandom.com/wiki/Series_One_%28Isadora_Moon%29) • [4](https://thetvdb.com/series/isadora-moon). In the United States, Max announced the premiere on January 2, 2025; at that time the series was reported as Sky Kids' top-rated show in the UK, with broadcasts already running in Italy, Sweden, Norway, Israel, and Canada[1](https://press.wbd.com/us/ca/media-release/isadora-moon-flies-us-max-animated-series-launches-january-2?language_content_entity=en). It has since reached further broadcasters including Tiji in France, TG4 in Ireland, TV Joj in Slovenia, Sky in New Zealand, RTVE's Clan in Spain, and DeAJunior in Italy[14](https://www.c21media.net/news/frances-tiji-sky-nz-abc-australia-among-nets-to-pick-up-isadora-moon-content/XXX/) • [15](https://www.rtve.es/play/clan/isadora-moon/) • [16](https://deajunior.it/news/656/su-deajunior-arriva-in-esclusiva-la-serie-animata-isadora-moon.html).
In the United States the series streams on [HBO Max](https://www.edgepedia.org/hbo-max) and the HBO Max Amazon channel[17](https://www.justwatch.com/us/tv-show/isadora-moon), and in France it is available on M6+[11](https://actu.m6.fr/jeunesse/isadora-moon-le-dessin-anime-parfait-pour-prolonger-les-vacances-de-printemps-sur-m6).
## Franchise and publishing
The television success has fed back into publishing. Oxford Children's launched a TV tie-in range in May 2026, starting with four picture books and four activity books for ages 4 to 7, followed by 14 additional titles, in a program planned to expand to 32 new books across two years[18](https://www.thebookseller.com/rights/oxford-childrens-shoots-for-isadora-moon-animated-series-tie-in-range).
A companion animated series, **Emerald** (18 x 11' plus one 22' special), also produced by Kelebek Media from a Muncaster book series, follows a mermaid who becomes a princess when her mother marries the sea king[19](https://worldscreen.com/tvkids/madgic-distribution-secures-first-sales-for-emerald/). International distribution rights for both series outside the US, UK, and Italy are held by Madgic Distribution, the renamed APC Kids, following its 2025 integration into the Madgic group[14](https://www.c21media.net/news/frances-tiji-sky-nz-abc-australia-among-nets-to-pick-up-isadora-moon-content/XXX/) • [20](https://worldscreenings.com/screening/isadora-moon/). A feature film, *Isadora Moon: The Movie*, is listed by Kelebek Media as in development[21](https://www.kelebekmedia.com/copy-of-stitched-the-movie).
## Reception
On IMDb the series holds a user rating of about 7.6 to 7.7 across roughly 70 votes[22](https://www.imdb.com/title/tt30332037). A Spanish review on Contraste scored it 7/10, calling it a kind and entertaining children's series built on simple ten-minute episodes with clean line drawing and flat colors[10](https://contraste.info/tv/isadora-moon/). Common Sense Media gave it a Common Sense Selection award[6](https://www.commonsensemedia.org/tv-reviews/isadora-moon).
