The character was created by Amy Reeder, Brandon Montclare and Natacha Bustos and first appeared in Moon Girl and Devil Dinosaur #1 (January 2016).
The genesis of the character came from Mark Paniccia and Emily Shaw who were a fans of the character Devil Dinosaur and had hired Montclare and Reeder to pen the basis for a new series that involved the character ending up in modern day. They came up with the idea of Devil Dinosaur interacting with a girl and fell in love with the idea of working with a hero who wasn’t a “regular cape-and-tights superhero”.
They also viewed the series as a direct sequel to the Moon-Boy and Devil Dinosaur series from Jack Kirby hence the first villains that Moon Girl and Devil Dinosaur face are the Killer-Folk.
Artist Natacha Bustos found the character a relief from the norm of other typical superheroes. She was primarily inspired by the clear diversity that Moon Girl and Devil Dinosaur promoted, further comparing the character Lunella to herself. She compared her story to a “Ghibli one” due to the immense relationship between the title characters.
