YMMV / The Scooby Doo Show S 3 E 13 A Menace In Venice

• Magnificent Bastard: Mario is a descendant of a former ruler of Venice whose lost fortune Mario covets and doesn't want to share with his distant cousin Antonio. Hiding his true identity, he befriends Antonio and researches the treasure. Upon learning that four medallions act as the key to the treasure chamber, he assumes the guise of the Ghostly Gondolier to steal them in a series of daring public thefts. He kidnaps Antonio and Daphne (who was wearing one of the medallions) to get the last two medallions and makes the gang think the Gondolier mistook Mario for Antonio and kidnapped him. He eludes pursuers using a rubber gondola that he can deflate and re-inflate within seconds. He succeeds in finding the treasure right before being confronted by the gang and is only captured due to a fluke of luck.
