Rose (also known as Huntsgirl) is a member of the Huntsclan. There is a birthmark on her right palm and wrist resembling a Chinese dragon, otherwise known as the "Mark of the Huntsclan". In episode 21 "The Hunted", Jake discovers that Rose is the Huntsgirl, and in turn, he shows her his identity as the American Dragon. After Rose's wish for all Huntsmen to be destroyed—herself included—(in episode 41 "The Homecoming") was granted, Jake immediately wished that Rose had never become a member of the Huntsclan. This ended their relationship, until the series finale "Hong Kong Longs" when Huntsgirl kills the Dark Dragon.
- Though constantly referred to as "Huntsgirl", Rose's original moniker as a Huntsclan member was "Thorn". It was discovered late in the recording of first season episodes that a DC Comics character already existed with the same dual-personality label of Rose and Thorn. For legal reasons, re-recording was done to replace all mentions of "Thorn" with "Huntsgirl". However, she is called Thorn in "Shapeshifter".
- In an early draft of "Homecoming", Rose was going to end up slaying Sun, but the Disney Channel considered it was too dark and too Jetix. Rose was also set to lose her memory, just as she did in the actual episode, and stay in New York without remembering Jake but the Disney Channel told the writers that it would be too confusing to those who missed watching "Homecoming". Rose moving to Hong Kong was a last minute addition.
- In "Dreamscape", it was revealed that Rose's last name was Killdragonosa. Her last name in this episode originally came from one of the early incarnations of American Dragon: Jake Long according to Eddie Guzelian and Matt Negrete. However, this is not her real last name. The last name she uses was given to her by the Huntsclan.
