Mr. Franklin is a watchman at Cass Elliot's candy factory.
The New Scooby-Doo Movies
He had been with factory since it began, for 50 years. After the two Green Globs were caught, the first one was revealed as Mr. Crink and the second one was revealed as Mr. Franklin. Cass couldn't believe it, and neither did Velma Dinkley; she pulled off his face revealing it was a mask. Detective Storm identified him as Sterling Smith, an international gold swindler. He had posed as Mr. Franklin to cover his tracks. Later, the real Mr. Franklin was found safe and sound at home, and came to the party Cass threw the gang as her way of saying thanks.
