Duncan

Duncan, labeled, was a camper on Total Drama Island as a member of the Killer Bass. He was a cast member and one of the finalists of Total Drama Action and was a member of the Screaming Gaffers. Originally, he quit Total Drama World Tour but was forced to return once he was found in I See London... and was placed on Team Chris Is Really Really Really Really Hot. He was seen with the original contestants on a yacht in the first episode of Total Drama: Revenge of the Island, and he had a cameo appearance in Grand Chef Auto. He was a contestant for Total Drama All-Stars and was originally a member of the Villainous Vultures, but was later switched to the Heroic Hamsters.

Personality
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 knows many tactics 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 (such as Owen, who is about twice his size). He's a sarcastic kind of person, flirting with Heather despite his apparent dislike of her, and mocking Courtney whenever she gets near him. He also gives Courtney the pet name "Princess" to tease her. 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 several pranks on them, with Harold being his main victim (later intensifying it due to a certain move Harold made in Total Drama Island). 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 mean demeanor, Duncan is actually a good person at heart, although he will never admit it to everyone else. Such moments displaying this side of him include finding a new bunny for his friend DJ after Geoff loses the first one, and defending Lindsay after she is betrayed by Heather. Some quality time with Harold also makes him consider ending his feud with him after so long, though this does not come to fruition. As a way to express his feelings for a girl he likes, Duncan uses his knife to either carve her name or her face. In Total Drama All-Stars, being on the Heroic Hamsters starts to bring out his nicer side (which infuriates him, as it ruins his "bad boy" image).

Total Drama Island
In Not So Happy Campers - Part 1, Duncan was the seventh camper to arrive. He was annoyed that the place isn't what he was told it would be, and angrily said that he doesn't like surprises, to which Chris says that Duncan's parole officer already told him that, and that he also told him to give him a call any time to send Duncan back to Juvie. After that, Duncan accepts the place. Duncan walks past Heather and flirts with her, saying that he'll meet her by the campfire. Heather rejects him, telling him to drop dead. Upon Noah's arrival, Duncan quickly gets into a conflict with him. Later, Duncan also threatens Harold, which marks the start of their conflict. He tried to flirt with Heather a second time, but she completely rejected it. Duncan is placed on the Killer Bass team. He shows his tough side on many occasions, such as bothering a deer and killing a cockroach by slicing it in half with an axe, to which everyone seemed impressed by.

In Not So Happy Campers - Part 2, the contestants had to jump off the cliff. Duncan did not want to jump at first, but later does so in a relaxed manner, showing not the slightest hint of fear. The Killer Bass lose the first challenge, so they have to move their hot-tub gear themselves. Duncan does so by kicking it constantly. Duncan mocks Courtney by calling her "cyclops," as her eye is swollen. He later gets into a fight over a hammer with Tyler. The Killer Bass end up losing and have to vote someone off. Duncan says he wants to vote off either Courtney or DJ as they're the only ones with the chicken hats on. He then adds that if they should have to lift a truck, he likes the odds with DJ, which annoys Courtney. Duncan then goes off to take a nap. At the Campfire Ceremony, Duncan tells Ezekiel he has a lot to learn about the real world. Duncan gets his marshmallow second to last.

Duncan, along with his pal Geoff defend Chris from an angry Eva in The Big Sleep, as he's explaining the twenty kilometer run around the lake. Duncan doesn't really seem to have very big problems with completing it himself. For the last part of the challenge Duncan does a great job at staying awake. During the time, Duncan pulls a prank on Harold, putting his hand in a cup of water while he's sleeping so that he pees in his pants. Duncan manages to get to the final two in the challenge along with Gwen. Then Duncan takes a bathroom break, but falls asleep there, losing the challenge. Duncan gets the first marshmallow and therefore stays.

As a result of the last challenge, Duncan is really tired in Dodgebrawl. Chris mocks Duncan about it, but he is too tired to do much. Harold has apparently snored all night, which means Duncan got way less sleep during the night. Some of the team has therefore drawn a mustache on Harold, which Duncan probably was a part of. Entering the dodgeball arena, Duncan lays down and says that if they wake him up, it'll be the last thing they do. Duncan then sleeps for the first two rounds, but when his team is down two to zero, they wake him up by jabbing him with a stick, which he gets pretty mad about. But Courtney convinces him to play, and says that if they lose another game, he'll be going home. Duncan makes up a strategy which is throwing all the balls at the same person, this tactic makes the Killer Bass win the next two rounds. In the final round, the Gophers start playing better again. Eventually they hit Duncan with his own tactic. When it's down to Owen against Harold, Duncan at first thinks it's over, but after Harold shows some dodging skills, and Courtney calls for a time-out, Duncan gets his hopes up for Harold. Harold wins and Duncan with the rest of the team cheers for him.

Duncan uses his defiance of the rules to his advantage. His rebellious habits land him much criticism from "by-the-book" Courtney. However, through her criticism, Courtney secretly forms a crush on Duncan. Duncan himself never denied having an attraction to Courtney. He often flirted with her openly. Eventually, in Basic Straining, he managed to get Courtney to break the rules by stealing food and they become a couple. Harold gets back at Duncan by opening the box containing the votes and replacing the votes with all against Courtney votes of his own saying, "Let's see how you like it when someone messes with your love life." When Courtney is kicked off Duncan is devastated. In No Pain, No Game, he votes for Heather to leave the island because he thinks she had something to do with Courtney being kicked off, not knowing that Harold is the real culprit. He then gives out a shout out to her on camera, telling her "I miss you, babe." In Trial by Tri-Armed Triathlon, he shows a rarely-seen sweet side of his personality when he carves "D+C" in a heart on the back of a wooden sculpture of Courtney's head.

He is the founder and leader of the first guys' alliance, and he is the only person to volunteer to be in Heather's Alliance. He is also the only guy in Heather's alliance and the only person to be in both alliances. During the meeting of the Guys' Alliance in Hide and Be Sneaky, he convinces Geoff, DJ, and Owen to eliminate Bridgette, due to her being likable and good at sports, but Geoff refused due to his crush on her. As it came down to Duncan and Bridgette for the final marshmallow, Duncan was safe, making Bridgette the next one to go. He also constantly says that he is a loner, although it's obvious he considers Geoff and DJ friends, and even Owen to some extent. He has had a few verbal exchanges with Leshawna, but nothing in the areas of violent offense.

He forms a reluctant alliance with Heather in Wawanakwa Gone Wild!. However, he seems to only want an alliance with Heather since she is his biggest competition. He even stated that he had a win-win situation; if Heather escaped from the bear he was helping her with he would have an alliance, and if she didn't she would get eaten by a bear. After the elimination ceremony, Heather makes him clean the bathroom as a punishment. He says that he and his brothers would build bikes together; he would steal the parts. In the serial killer challenge, when watching a horror movie with the other campers, it is revealed he and Gwen both like the same movie. When Leshawna told him, while they were cuffed together in a challenge, that she knew about Duncan secretly replacing DJ's pet Bunny, he revealed that his dog ran away when he was six, and that he didn't want DJ to go through the same thing. In Camp Castaways, he teamed up with Gwen with a prumess to share his egg with her. He was the fourth to last camper voted off, thus he is the last Killer Bass to be voted off after DJ and Geoff were voted off, leaving only former Screaming Gophers by the end of Are We There Yeti?. Duncan leaves saying, "Good, get me out of here," implying that he hated the island and just wanted to leave.

In the special, he and Courtney teamed up in order to find the case with the million. Though Duncan manages to wrestle an alligator that ate the case, he trips on a rock and sprains his ankle. Despite his pleas for help, Courtney abandons him, taking the case with her (to which he says he loves that woman). Noah comes by and mocks Duncan, causing him to rip his pants off. Duncan manages to make it back to camp, but is attacked by a moose. However, he wards it off with the moose head from the mess hall. When Courtney cheers him on, telling him to "go honey go!" He threatens her saying he's coming for her next. Duncan is soon caught in a stampede and is one of the fourteen people to make it to the dock and Total Drama Action, but Courtney falls in a tub below the diving board and doesn't make it in time.

Total Drama Action
Duncan returns for the new season, continue his role as the series' anti-hero. From the beginning, he and Gwen had become close friends due to the both of them having many interests. This made Gwen's boyfriend, Trent, jealous, especially when Gwen chose Duncan as the first member of her team. Unaware of his anger, Duncan begin to pull pranks on Trent, angering him even more. Trent's jealousy had made him become obsessed with the number 9 and Duncan only made it worse after telling Gwen the possible connection between the number and their relationship. This leads to a series of events in which leads to both the break up of Trent and Gwen and their subsequent elimination. Duncan was one of the few people (the other being DJ) who still defends Gwen after she is caught throwing the challenge for the other team. He even tries to take her place in the Lame-o-sine but admits that he was only kidding. Before she leaves the show, Gwen tells Duncan good luck.

With Gwen's departure, Duncan unofficially replace her as captain of the Screaming Gaffers. He had win many challenges for his team, earning him the respect from his teammates. However, his hatred for Harold hasn't changed. It is revealed that Duncan had found out about Harold's action last season that caused Courtney to be eliminated, leading to Duncan to intensify his mistreatment to him. In addition to this, Duncan also occasionally mock Harold's feelings for Leshawna. Despite their feud, the both of them are occasionally partner up in challenges where they admit they had a small degree of respect for the other.

When Courtney return to the competition in Ocean's Eight or Nine, Duncan begin to lose his focus on the challenges. While he still has feelings for her, Duncan hated the fact that Courtney would stood so low into using dirty tactics to make sure she wins the season. Courtney on the other hand is angry at Duncan for being close to Gwen, believing that he is cheating on her. Whenever they are pair up during challenges, Courtney will not hold back and brutally beats Duncan up, who tries his best not to have his relationship with Courtney ended up like Trent and Gwen. In addition to this, Courtney's enemies begin to target him after the merge, believing that eliminating him would made Courtney lose her edge. However, through sheer luck or otherwise, Duncan manage to avoid getting eliminated.

With the two of them reaching the merge, Duncan and Harold's conflict intensify. The two of them would ended up being in two different alliances but they still get on each other's throat. In Crouching Courtney, Hidden Owen however, the two of them begin to make amends after winning the first challenge. Neither of them wanted to sabotage the other and even agrees in sharing the reward together. Just as things between the two are becoming better, Owen, under orders from Chris, convince Harold to punch Duncan which he does so after Duncan make fun of Leshawna, ending their short-lived friendship. This action gives Harold enough confidence to give Duncan a taste of his own medicine by putting rocks on his bed in 2008: A Space Owen. After Harold accidentally killed Duncan's beloved pet tarantula, Scruffy, Duncan voted him off. Before he leaves, Harold pantsed Duncan, to which Duncan states that he probably should had see it coming.

In Top Dog, Duncan and Courtney spend the night before discussing about their relationship and Courtney decides to give him a chance, provided that he read and memorise a thirty-two page long letter that highlights all the mistakes Duncan needs to correct. This cause Duncan to be sleepy for most of the challenge. In the forest, Duncan's chameleon disappears and he ended up falling into a pit. Duncan slowly begin to lose his mind and to quench his hunger, he eats the letter Courtney give him. Two days later, Duncan returns to the film lot, dressed up as a wild man and armed with primitive weapons. In wasn't until Courtney kissed him that he return to his normal self. Owen then tells him that his chameleon was with him the entire time, blending with the colour of Duncan's mohawk. Tired of Courtney's overbearing rules and control over him, Duncan voted him off that night. Angered by his betrayal, Courtney break up with him. Moments later, Owen was fired by Chris, leaving Duncan and Beth the only contestants remaining in the season.

During the finale, Duncan declines Beth's idea of working together for the challenge as he wanted to claim victory for his own. He manage to get a head start of Beth during the first challenge but he is unable to answer any of the questions Chef asked correctly, he is required to compete all the season's challenges again. Beth eventually catch up with him at the final question since she knew much about her fellow contestants. To Duncan's delight, the final question is about Courtney, whom he supposingly know a lot about. Unfourtnately, the question is something he don't know; "What colour is Courtney thinking of?". As both finalist are unable to answer the final question correctly, they had to compete the earthquake stimulator challenge again. Duncan and Beth ended up helping each other to make it to the finish line, resulting in a tie. In order to break this tie, Chris had the eliminated contestants to vote for the winner, after asking them questions. No matter which ending occurs, Duncan ended up back with Courtney.

It is reveal in Celebrity Manhunt's Total Drama Action Reunion Special that despite the couple's popularity, Duncan and Courtney broken up again and Duncan had file a lawsuit against Courtney over custody of their pet raccoon, Brittney (a parody of broken up couple fighting over custody of their child). Meanwhile, rumours begin spreading that Gwen is beginning to have a crush on Duncan, putting the situation in a tense position. Duncan joins his fellow contestants to New York to stop the Dirtbags but en route, he and Courtney ended up making out, sending their bus off a cliff. He remains at the bus with several others while Geoff finds help. Eventually, he and those who remained are saved by Chris who announce that they qualifiy for season three, Total Drama World Tour.

Total Drama World Tour
Duncan starts the third season in a very good place with his recently reunited girlfriend Courtney, and his close friend Gwen. Like Gwen, Duncan strongly oppose of the idea that the contesants are required to sing every episode. In Egypt, Duncan and the two girls would work together during the first challenge, but things get tense between the girls, which annoys him immensely. Once his team makes it to the top of the pyramid, the two girls continue to argue and Chris shouts at them to get down, as it's time for another musical number. Duncan finally snaps and runs down the pyramid, dragging Courtney and Gwen along with him and yells at Chris that he quits, shocking both Gwen and Courtney. Duncan would officially leaves via the Drop of Shame in the next episode after Ezekiel had taken it. The exclusive clip shows that after having trouble activating his parachute, Duncan is dangle from a tree and is surrounded by scarabs.

From his departure, and for the rest of the first half of the season, Duncan would be mysteriously spotted all around the world, in places like Scotland, Sweden, Texas, and Italy. His disappearance and sightings had been included into an Aftermath segment called "Total Drama Fugitives." It was also mentioned by Blaineley that Chris had been searching for him, even sending giant Drama Machines everywhere. His absence was also brought up by Gwen and Courtney in Newf Kids on the Rock, both accidentally reveals how much they miss him in the confessional (though the former mistaken him being her boyfriend last season instead of Trent). While Team Amazon are on their way to Newfoundland, the two girls believe they saw him standing on top of a mountain but in turns out to be a rock formation that resembles him.

Eventually Duncan ended up in London for a performance with his brand, which coincident with the latest country the contestants are visiting. He was captured by the two girls he is closest too when they bump heads in a club at Whitechapel and is brought back to the plane. Upon discovering where he is, Duncan quickly looks for an exit, but Chris stops him, revealing that the whole challenge was a plan to drag Duncan back and force him to fulfill his contract (much to his chagrin). He is soon placed on Team Chris Is Really Really Really Really Hot. He is soon scolded by Courtney for abandoning her before the two embraced but at this point, he is completely over Courtney, and has grown romantic feelings for Gwen. While Gwen is using the confessional, Duncan accidentally barged in and after a brief banter, the two ended up kissing, with Tyler as their sole witness. In Greece's Pieces, Duncan threatens Tyler to not reveal about the kiss he had with Gwen. Unfortunately, Tyler was pressured by Alejandro to reveal his secret during the tie-breaker challenge. Upon finding out that he lost another chance to be with Gwen again, Cody angrily punches Duncan, starting a conflict betwen the two. With a target on his back, Duncan was supposed to be eliminated that night but Chris wanted to prolong the drama and eliminates an intern instead. After a messy break up with Courtney, he and Gwen would officially starts a relationship after they shared their second kiss in The EX-Files. Unfourtunately, their time together was short as Gwen is eliminated in the next episode as a result of Cody and Duncan fighting. Duncan however would not forget about her, and is seen carving a picture of her face on the side on one of the first lounge chairs.

It is around this time where he started getting involved with Alejandro, with both getting involved with two women on the season. They both come up with a plan to mess with Team Amazon, by pretending to fight over Courtney, and for Alejandro to flirt with Courtney, so Heather would be jealous, and the team would completely self destruct. Duncan, however, admits that he does not trust Alejandro in Sweden Sour and advice Owen to do the same, using Noah's absence. Once the teams are merged, he thinks that Gwen is going to return (missing her dearly), only to be told that someone else will be returning. Duncan is forced to work with Courtney for the challenge, and despite their bickering, they manage to win immunity for themselves. In order to get rid of Courtney and secure Alejandro's vote, Duncan agrees to team up with him though he still has his suspicions over him. Regardless of Alejandro going against his deal, Duncan is finally be able to eliminate Courtney in Chinese Fake-Out and was not even afraid of her treats. In the next episode, Duncan and Alejandro teams up again but he is soon stabbed in the back when Alejandro teams up with Heather to vote him off. While taking the Drop of Shame again, Duncan happily announce to Gwen that he would be seeing her soon.

Duncan is introduced as a guest along with Owen and Courtney in Hawaiian Style, where he is reunited with Gwen. Though Courtney continues to annoy them, the couple nevertheless ignores her until Duncan loses his patience and threw a sandal at Courtney. He and Gwen then smile at each other and then share a kiss. Despite his conflict with Cody, Duncan chose to support him over Heather and Alejandro, knowing that he is the lesser evil among the final three. Unfoutunately, Cody lost in the tie-breaker challenge in Hawaiian Punch and Duncan switch sides to Heather instead. When Heather is declared the winner in her ending, Duncan cheers her for defeating "La Cucaracha." Duncan is last seen swimming away from the island with the other contestants when the volcano begin to erupt.

Total Drama: Revenge of the Island
In Bigger! Badder! Brutal-er!, Duncan appears on the yacht with his fellow veterans. He and Gwen are making out passionately while DJ, Harold, and Leshawna dance nearby.

Duncan still owes Chris camera time for quitting last season, and was caught in order to demonstrate the challenge in Grand Chef Auto. However, Duncan runs away once Chef unties him. As revenge for Chris using his kitchen as the site for the challenge, Chef later points the newcomers to paint Mt. Chrismore, and he blames it on Duncan. At the end of the episode, Duncan returns and blows up Mt. Chrismore while laughing maniacally.

Total Drama All-Stars
Duncan is one of the all-stars chosen to return to the competition in Heroes vs. Villains. Once he arrives, he is put on the Villainous Vultures alongside his girlfriend Gwen, much to her chagrin. Although he reassures her by saying that "being bad is cool," she still does not approve of her team placement. Later, while walking through the woods on their way to the cliff for the season's first challenge, Duncan glares back at Courtney once he catches her looking at Gwen, but Courtney does not react to this, confusing Duncan. The Vultures later win the challenge, mainly thanks to Alejandro's unexpected return, and Duncan is exempt from elimination.

In Evil Dread, Duncan enjoys the treatment he received at the McLean Spa Hotel and over hears Jo and Scott discuss about voting off Lightning. During the challenge, Duncan tries to help his team out during the challenge, but they lost because of Lightning miscounting the pieces. Later at the elimination ceremony, he earns the first marshmallow of the night.

In Saving Private Leechball, Duncan was frustrated at Heather, Jo and Alejandro for fighting over Gwen's loyalty in order to get her to form an alliance with one of them. During the challenge, Duncan saves Gwen from getting hit with a leech by jumping in front of her and taking the blow himself. In the end, the Villainous Vultures lost and they voted Jo off. Chris also makes Duncan switch teams with Courtney as his sacrifice for Gwen was deemed heroic. Despite his and Courtney's protest, Duncan gets up and joins the Heroic Hamsters after giving Gwen a kiss on the cheek. When Duncan encountered Courtney, he says that she has to stop blanking him, but Courtney scared him, prompting Duncan to wanting to be blanked by her for now on.

Duncan is annoyed by the fact he has the "hero" title in Food Fright. When he wakes up in the morning, his new team has set up a surprise welcome party for him. In the confessional, he believes that the others are trying to let his guard down so they can vote him off. Although he expresses his embarrassment and hopes his friends from juvie doesn't think of him differently, Duncan appears to be enjoying the party. Throughout the challenge he finds himself acting differently than normal, perhaps more like a "hero," engaging in activity like blowing kisses and cheering for his teammates. When Mike said it was okay to root for Sam, Duncan mentions that Mike's voice sounds familiar.

In Moon Madness, Duncan was pretending not to be jealous of Courtney's new found of attraction on Scott. When he was separated from the team, he overheard Mike talking to a bird. Finding his voice familiar, Duncan confronts Mike again but he sends the bird to attack him. He later stumbles across Gwen and saves her from a group of aggressive squirrels. Suddenly, Duncan started asking Gwen about Courtney which makes her jealous. Duncan soon reunites with his team but they lost when Mike fails to cross the finish line before Courtney and Gwen. During the elimination ceremony, his relationship with Gwen ended when he continues to ask her about Courtney.

Duncan realizes that he has been acting more nice and trusting in No One Eggspects The Spanish Opposition. He blames it on the influence he is surrounded by and tries to be more bad. Throughout the episode he ends up being helpful like lifting up Scott after he fell or when he comforts a bird while he borrows her egg. After the elimination ceremony, Duncan realizes why Mike sounds so familiar to him after hearing him whistling. When Duncan first went to juvie, Mike, who was known as "Mal" at the time, was also an inmate there and also was "bad news."

Duncan is slowly starting to accept being a nicer person in Suckers Punched despite his objections. While the contestants are walking to the Chrisiseum, he tells Zoey about Mike and that he went to juvie under the name Mal. She does not believe him at first but he explains the fact Mike has multiple personalities and the string of broken items, it is possible that Mike and Mal are the same person. Duncan hopes that the boxing challenge would show that he is still a bad boy but Chris paired him with the bird he met from the previous challenge. Duncan refuses to fight as he wouldn't hit an innocent bird and forfeits the challenge. That night, he discusses with Zoey about the possibility that Mal could be the actual personality instead of Mike.

Visibly sick of being labeled nice in You Regatta Be Kidding Me, Duncan tried to show off his "Bad Boy" reputation by doing some bad things, only to have them shown to be good instead. First, he tried to write graffiti on the side of a cabin, only to have Zoey say it looks like a bunny. He also tried to drive Chef's jeep into the lake, only to be shown fixing it, since it didn't work. Once the challenge started, he tried to ally himself with Courtney and Gwen under the promise to protect them from Mike, but they refused by claiming that Mike wasn't a threat. Since Mal had sabotaged the boats, Duncan and Scott hitched a ride on Cameron and Zoey's raft. He caught a stick of dynamite to protect the raft when Zoey spotted Chris's cottage. To prove he was a Bad Boy, he blew up the cottage, and proclaimed himself the ultimate bad boy. At the elimination ceremony, Chris had Duncan arrested and removed from the show since the cottage was private property. However, Duncan was ecstatic about going to juvie until Chris revealed he was going to a real prison facility. He attempted to talk his way out of it, but was unsuccessful.

Audition tape

 * View this video for Duncan's audition tape.

Duncan talks about his qualities while climbing down the wall of the juvenile hall he was staying at. But as soon as he hits the ground, he gets hit by a search light, the alarm goes off and guard dogs are heard about to approach him. Duncan then says it's been nice chatting, but he's gotta run, he then runs off into the dark. It is unknown how he was able to video tape himself climbing down the wall and then zoomed out picture to when he is caught by the guards, though it may be possible that he actually used the security cameras to film the video.

Video log
Duncan's parents and his parole officer send him a video log just like the other campers in the final five of how much they miss them. His parents tell him that they love him despite the fact that he got arrested for the "Happy Nude Year Stunt,” for selling his father's hairpiece as pets, or for the pool party at City Hall fountain. His parents start bickering after his father questions if they really love him, which appalls his mother, who then insults her husband's hairpiece. Duncan's parole officer then inquires about the pool party. It ends with his father telling him to win the money for his lawyer; as he'll need it.

Camp TV
Duncan was one of the campers who appeared in the prototype of the current series; Camp TV. He was also one of the main characters of the show, as he appears in nearly every scene of the promo and the promotional art. Like his current character, he was a crook from Juvenile Hall who bullied everyone on the island. However, despite his bullying, he seemed to be close friends with Tyler; the two were in a canoe giving each other a high-five before discovering they went over a waterfall.

Duncan appears to be friends with Gwen, as she has her hand on his shoulder and is smiling in the promotional art. Duncan was one of the few campers to go practically unchanged in his design, the only difference being in his facial expressions. However, Duncan is one of the few characters who had an even older draft design that looks completely different from his second and current design. The only known evidence that this was Duncan's first design is a File sheet which displays the original versions of the campers and their designated names. This design appears in the promo and is seen with Harold and Beth, but it is instead used as Cody's. This design has since been recycled into one of the interns.

Trivia

 * He directly eliminated Bridgette, Geoff, Harold, and Tyler.
 * He indirectly eliminated Izzy, Lindsay, Courtney, Gwen and Noah.
 * Duncan had been indirectly and directly responsible for both of his girlfriends' eliminations in the first three seasons:
 * In Basic Straining, Duncan's constant abuse of Harold is what caused Harold to rig the votes in order to eliminate Courtney.
 * In Top Dog, Duncan voted Courtney off, after she gave him a thirty-two page letter about all of his faults, and how Duncan would have to memorize the whole letter, fix the issues, and ultimately become a "better boyfriend" to Courtney.
 * Duncan is technically responsible for Gwen's elimination in Picnic at Hanging Dork. If Duncan had never thrown the dingo at Cody, then Cody would have been able to vote for Courtney and the tie-breaker between Gwen and Courtney would not occur.

 * He was a contestant for Total Drama All-Stars, which also takes place on the island.
 * Like Trent, Justin, Alejandro, Harold, Mike, and Dave, Duncan has more than one girl attracted to him.
 * Duncan often lets his feelings for a girl get the better of him, resulting in several consequences:
 * In Are We There Yeti?, Heather pretends to be weak and defenseless to him in order to steal his map. This cause him and Owen to lose and his subsequent elimination.
 * In both One Million Bucks, B.C. and Million Dollar Babies, Duncan has problems fighting Courtney as he doesn't want to have their relationship ended up like Trent and Gwen. Courtney however has no problem hiding her feelings and dominates him in both episodes.
 * In Get a Clue, Courtney flirts with Duncan by giving him a massage to steal his DNA. Later in the train, she encouraged him to get on top on the train, injuring him.
 * In both Super Hero-ld and Rock n' Rule, he was targeted by the other contestants as eliminating him would anger Courtney
 * In African Lying Safari, Heather reminded Duncan that he causes Gwen's elimination in Picnic at Hanging Dork. Duncan doesn't take this lightly and glares at her. This, however, serves as a distraction, allowing Alejandro to trip Duncan into a bush containing Serengeti Blood Berries that attracts Ezekiel to attack Duncan. He was also voted off, later in the episode.
 * As seen in Rock n' Rule, Duncan is able to play the guitar, making him one of the few contestants to know how to play a musical instrument.
