DragonQueen is the fan-dubbed name of the Maleficent/Regina Mills ship on ABC's Once Upon a Time.
- Regina met Maleficent in the Enchanted Forest, and helped her get revenge.
- Regina and Maleficent remain friends, even after Regina becomes the Evil Queen, and Regina gives the Dark Curse to her in exchange for the Sleeping Curse.
- Regina later traps Maleficent in the form of a dragon underneath the Storybrooke clock tower for almost 30 years during the first Dark Curse.
- Maleficent is resurrected, but she harbors no grudge against Regina. Regina "allies" herself with Maleficent when attempting to infiltrate the Queens of Darkness.
- Maleficent is based on the sorceress (who can turn into a dragon) from Sleeping Beauty and Regina is based on the queen from Snow White, hence the name "DragonQueen".
- DragonQueen is a non-canon ship.
