Thorn is the leader and lead singer of the Hex Girls in the Scooby-Doo franchise.
The Hex Girls are a fictional eco-goth rock band introduced in the animated film Scooby-Doo! and the Witch’s Ghost. Thorn performs with Dusk and Luna, and the trio combines supernatural imagery with environmental themes. Their look and music made them one of the franchise’s most recognizable recurring musical groups.
Thorn is commonly identified as the band’s lead singer and principal front person. Dusk and Luna are also important members, but neither is the group’s leader. The characters’ names can be difficult to remember because all three use short, stylized stage names associated with night, magic, or darkness.
The Hex Girls returned in later Scooby-Doo productions, including television series and direct-to-video films. Their popularity led to appearances beyond their debut story, but Thorn’s role as the group’s central singer remains the key fact for this question.
