The series features the voices of Diamond White, Fred Tatasciore, Alfre Woodard, Sasheer Zamata, Jermaine Fowler, Gary Anthony Williams, Libe Barer, and Laurence Fishburne.

Development began after Marvel Studios president Louis D'Esposito showed Fishburne the comic book Moon Girl and Devil Dinosaur.

Marvel's Moon Girl and Devil Dinosaur premiered on Disney Channel on February 10, 2023, and was released on Disney+ five days later.

Chibi Tiny Tales is a series of shorts that depict characters from various Disney Channel properties in chibi-style animation.

During discussions with Marvel Studios regarding a potential collaboration with Cinema Gypsy Productions for a Marvel Cinematic Universe (MCU) project, president Louis D'Esposito showed actor and comic book fan Laurence Fishburne the comic book Moon Girl and Devil Dinosaur.

[79][80] Having read the original Moon-Boy and Devil Dinosaur comic book as a child, Moon Girl piqued Fishburne's interest.

[82][80] Loter and the team then created a roller-skating sequence played over "Sweatpants" by Childish Gambino as a proof-of-concept piece and pitched it to both executives at Disney Television Animation and a Marvel Studios team including Brad Winderbaum and president Kevin Feige, who greenlit the series for development.

[83][84] On February 20, 2018, it was reported that Marvel Animation and Cinema Gypsy Productions were developing a Moon Girl and Devil Dinosaur series for Disney Channel Worldwide.

[91] Fishburne said that "Disney Channel is the perfect platform to explore this pint-sized female African American superhero and [he] can't wait for their audience to enjoy the lighthearted adventures of Lunella and Devil Dinosaur",[88] while Cort Lae, Marvel Family and Entertainment's then-senior vice president, said that "[Moon Girl's] adventures with giant buddy, Devil Dinosaur, are filled with so much wonder and joy, and this historic partnership with Disney Television Animation and Cinema Gypsy Productions proved the right formula to bring them to television".

[83] The crew also worked alongside Disney production coordinator Allen March to identify moments to add diversity to the show via background or speaking characters, as well as to calculate the representation per episode.

[101] The series starts off with an episodic format as it explores Lunella becoming Moon Girl, before transitioning into a more serialized story, with an arc unfolding throughout the first season.

[96][102] Supervising producer Rodney Clouden said it was important for the production crew to accurately portray a multigenerational African-American family.

[104] Producer Pilar Flynn said it was important for the writers to have Moon Girl and Casey have a close and supportive relationship, which is rarely seen among female friendships in animation.

[105] The series portrays the relationship between the duo as "a partnership" instead of "a pet/owner dynamic", with Devil becoming fiercely loyal to Moon Girl and feeling "at home with her" due to how she treats him.

[103] The producers changed Lunella's age from 9 to 13-years-old because they wanted social media to play a prominent role in her character, which they felt would not work with her being 9-years-old.

[107] Some of the villains represent real-life issues within the show, such as Aftershock draining the Lower East Side's energy in the first episode, which serves as "a statement" about gentrification.

[96] Williams, whose work on the show was his first role during the pandemic, received help from his wife to prepare to record his lines from their home.

[96] White and Barer ad-libbed several dialogues between Moon Girl and Casey,[96] with the two recording their lines simultaneously either physically or through Zoom.

[115] For his performance, Fishburne wanted it to be lighter and less recognizable than his previous roles, so he and Loter worked together to develop his voice for the Beyonder.

[85] Flying Bark, whose employees were fans of the source material, was hired due to the studio's work on Rise of the Teenage Mutant Ninja Turtles.

[96] The camera movement was also meant to evoke the feeling of a real-life city recording, with "forced tight shots" and "object obstruction".

[120][121] The artists also incorporated elements to visually represent the characters' feelings, such as manga-style "flairs",[119] as well as emojis that were "simple and clear and direct".

[103] According to Flynn, the crew generally pitched ideas for the score to Saadiq, only for him to discard them in favor of something different, which the producers received positively.

[94] Saadiq said he wanted the song to be both "uplifting" and "happy", while White was excited to "bring Lunella's voice to the show in a singing way".

[125][126] James Whitbrook of io9, after reviewing the leaked footage, noted that "the episode is clearly not subtle" with its focus on Brooklyn and "the explicit prejudice she faces as a trans teen who wants to participate in school sports".

[125][127][58] Michael McWhertor of Polygon reported that a Disney source stated the episode was held instead of banned, with that determination occurring "more than a year ago and was not based the result of recent U.S.

[125] Whitbrook reported that a Disney source claimed the intent of the hold was "to ensure material doesn't potentially push ahead discussions around social issues before families can have them themselves", however, Whitbrook also commented that "it would not be the first time Disney has capitulated to right-wing systems of power by censoring its own material".

[137][138] A soundtrack featuring songs from the first season, in digital and audio cassette formats, was released on January 4, 2023 by Walt Disney Records.

The site's critical consensus reads: "With dazzling visuals and punchy pacing that feel beamed straight from a child's imagination, Moon Girl and Devil Dinosaur will enthrall kids while impressing animation connoisseurs.

"[141] Matthew Aguilar of ComicBook.com gave the series a 4 out of 5, writing, "Marvel's Moon Girl and Devil Dinosaur is an enchanting adventure that wears its heart and charm on its sleeve.
