At some point, Mark, and the rest of Sugar Ray, were captured and possessed by the demons at Spooky Island.
The day after various people were kidnapped at the Spooky Hotel, they were performing on the beach, Mark was playing on the guitar, where Daphne quickly saw their true nature. When the demons began going on an all out attack, they joined the group led by the demon-possessing Fred in chasing Shaggy and their main target Scooby-Doo. They chased them down to a shed, which they began breaking down once the duo locked the doors, however, the duo escaped on Spooky Island-branded ATV bikes.
