This is the first of many Greek and Roman-inspired episodes that have been produced in the Scooby Doo franchise.
In this episode the gang takes a trip to Greece and on their visit to Helios Island they meet some natives who are terrified of the Minotaur that is ravaging the island. The Minotaur lives in a temple and chases the gang through a labyrinthine maze. In the end, the talking Minotaur is revealed to be local man Nick Papas, who was attempting to smuggle treasures from the island and on to the black market.
