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

Fred, Daphne, Velma, Shaggy and Scooby-Doo travel to an amusement park called Kiss World to see Kiss at their big Halloween concert and solve a mystery, mostly because Daphne has a crush on Starchild, much to Fred’s jealousy. After Scooby and the gang arrive, security chief and former government defense employee Delilah Domino refused to let them in, so they sneak in and are caught by Delilah. At that moment, Kiss arrives, and after the gang explains they are there to help, they tell Delilah the kids are free to stay, to which she reluctantly agrees. The Demon initially opposes the idea due to Scooby accidentally spraying a water gun on him when he came to Shaggy and Scooby for a surprise visit, but later relents.

As the gang split up for clues, Shaggy and Scooby are chased by an entity; Kiss comes to their aid. They tell the gang the entity is called the Crimson Witch, and she has been terrorizing the park for a while, and they need her to disappear before the concert. A strange fortune-teller named Chikara says the witch is from an alternate universe called Kissteria and plans to use the Black Diamond Kiss uses in their hit song “Detroit Rock City” to summon a monster called The Destroyer to conquer the Earth, which Velma finds hard to believe. To stop the Crimson Witch, the gang uses the diamond to lure the witch. However, the Crimson Witch chases them through a portal to Kissteria. She manages to steal the diamond and unleash The Destroyer, but the gang and Kiss arrive in a spaceship to stop the monster.
