The KPop Demon Hunters franchise is expanding its merchandise lineup with a Lego set, a line of school backpacks, and an officially licensed karaoke machine. The Lego set, designed in record time, features the characters Derpy and Sussie with movable parts for different poses and adjustable facial expressions. The backpack collection, aimed at the upcoming school year, includes styles for HUNTR/X, the Saja Boys, and Derpy and Sussie, with 3D and glow-in-the-dark designs. The karaoke machine, also officially licensed, is a portable setup finished in the film's purple colorway and bears the HUNTR/X logo. It is designed for amateur singers and fans alike, fitting the franchise's "soda pop" pop-star theme.
