History
While the Mystery Inc. gang was invited to Spooky Island for a mystery by Scrappy-Doo, Daphne encountered the Voodoo Maestro. He warned Daphne to stay away from the Spooky Island Castle. She believed he was using reverse psychology but he was in fact telling the truth so that Daphne wouldn’t touch the Daemon Ritus. As the crew found the Daemon Ritus, they believed that the Voodoo Maestro is one of the three suspects alongside N’Goo Tuana and Emile Mondavarious (actually Scrappy with a disguise).
