The Hex Girls Thorn, Dusk, and Luna are Velma's favorite band. They will appear in episode "In Fear of the Phantom".
She is the band's lead singer and guitarist. From all of the Hex Girls, Thorn is the only one whose real name is known (Sally McKnight). She is quite shy when she is not in the stage, and claims that she is "1/16 Wiccan on her mother's side", later becoming a practitioner. She has black and red long hair, green eyes, and wears a black and red dress in The Witch's Ghost, but a red and purple dress in The legend of the vampire.

She is the band's drummer and back-up singer. From the three of them, Dusk reveals herself to be the fiercest of the group, as well as the rebel of the band, and does not like to speak much about herself. She also tends to show that she is tough, but on rare occasions, she displays a very strong feeling of love and friendship towards her friends. She has blonde hair and usually wears it in pigtails, and wears a green dress. In the What's New Scooby Doo episode "The Vampire Strikes Back" it was revealed she was leaving the Hex Girls to go solo (although this was probably just a rumor that was published in the magazine that Daphne was reading, because thoughout the episode there are no more references to that subject).
