Scooby-Doo

After Mystery, Inc. solves the mystery of the Luna Ghost, long-brewing friction between Fred, a glory hog, Daphne, who has become sick of being the one who gets captured, and Velma, from whom Fred regularly steals credit for her plans, causes the gang to disband, making Scooby and Shaggy feel abandoned. Two years later, the gang grudgingly reunites after being invited to solve a mystery on Spooky Island, a horror-themed tropical resort owned by Emile Mondavarious. Mondavarious claims the visiting tourists have been brainwashed. Velma attends a ritualistic performance hosted by actor N'Goo Tuana and his henchman, Zarkos, a famous luchador. N'Goo claims ancient demons once ruled the island but have been plotting revenge ever since they were displaced by the resort. Meanwhile, Shaggy falls for a girl named Mary Jane, distancing himself from Scooby in the process.
