Scooby-Doo! And Kiss: Rock and Roll Mystery (2015)

Scooby-Doo! and Kiss: Rock and Roll Mystery (2015), released in 2015, is an animated crossover comedy mystery film, marking the twenty-fifth installment in the series of Scooby-Doo films. The gang – Fred, Daphne, Velma, Shaggy and Scooby-Doo – head to Kiss World amusement park for their Halloween concert, with Daphne’s crush on Starchild driving their motive. Despite opposition from security chief Delilah Domino, a former government defense employee, the gang sneaks in. However, they are quickly caught by Delilah who accuses them of vigilantism and bans them from the park. Fortunately, Kiss arrives at that moment and after learning of the gang’s intentions to help with the mystery at hand, they convince Delilah to let them stay despite her initial reluctance. Although The Demon is initially against this due to a mishap involving Scooby’s water gun during his surprise visit to Shaggy and Scooby-Doo, he eventually agrees.

As the gang splits up to search for clues, Shaggy and Scooby are pursued by an entity. Fortunately, Kiss comes to their rescue and reveals that the entity is known as the Crimson Witch. She has been causing chaos in the park for some time and Kiss needs her gone before their concert. A peculiar fortune-teller named Chikara explains that the witch hails from a parallel universe called Kissteria and intends to use the Black Diamond featured in their hit song ‘Detroit Rock City’ to summon a destructive creature known as The Destroyer in order to conquer Earth. Velma is skeptical, but determined to stop the witch. The group lures her out using the diamond, but she follows them through a portal into Kissteria. There, she manages to steal the diamond and unleash The Destroyer, but with help from both Kiss and the gang aboard a spacecraft, they put an end to her plan.
