Duncan (Thomas & Friends)

Duncan is a 0-4-0 Douglas-type narrow gauge engine in Thomas the Tank Engine & Friends. Duncan has an infamous talent called "Rock N' Roll", which always gets him into a lot of trouble. He can be bouncy, rough, grumpy, rude, stubborn, and usually misbehaves but always ends up getting bad karma in the end. But in later seasons of the show he has grown far more of a respectful, responsible and really useful engine. He changed his ways of his previous bad behavior. He also appears in a cactus190706 YouTube model movie called Sodor's Long Forgotten Secret as the primary antagonist until the main protagonist along with the Skarloey Engines.
