Duncan, labeled The Delinquent, was a camper on Total Drama: On the Island, as a member of TBA.
Serving as the primary anti-hero of the series, Duncan is a punk and a juvenile delinquent who ironically comes from a long line of policemen and policewomen: his dad, mom, uncle, aunt, grandma, and cousins are all cops. He has many skills from his time spent in juvenile detention centers. He can carve a picture of a skull into a tree trunk and lift great amounts of weight. Duncan loves to break rules to better suit himself, but sometimes the consequences are worse than what he intended. Duncan also loves to make fun of the other contestants and pull pranks on them. He considers himself as being "straight with people," never pretending to be what he isn't, and has been shown to either get along with fellow competitors or make fierce enemies because of this. Despite his harsh tendencies, Duncan is actually a good person at heart, although he will never admit this to everyone else. As a way to express his feelings for a girl he likes, Duncan uses his knife to either carve her name or her face, and has been shown to do this many times, which shows his soft side.
When Duncan is introduced to the show in Jump for your Life he immediately gets a bad impression of the island. Geoff is the first person to introduce himself to Duncan, and they quickly bond. During Duncan's first challenge Duncan calls Courtney princess which catches her off guard, and after he jumps off and tells her to watch and learn she states in her confessional that she irritates him. However, he encourages her to jump off the cliff into the water. After the Salmon win the challenge, Duncan goes and steals Chris's stereo and brings it back to the guy's cabin. Duncan, Geoff, and the rest of the guys enjoy a night of listening to tunes.
