This article focuses on the interactions between Everyone and Duncan.
Duncan's reputation amongst the other contestants is not easily defined as good or bad. He is not antagonistic, but loves causing mischief and making jokes at their expense. While a majority seem to dislike him, he is not shunned to the levels of people such as Heather, Courtney, and Alejandro. He even gains enough support from them to win Total Drama Action in his ending of The Aftermath: IV. Duncan is well known for being tough as nails, but there have also been plenty of instances where he is genuinely nice. He has a sweet side that he prefers to keep hidden from most of them, as when his good deeds are exposed, they have a tendency to get him teased.
In Total Drama All-Stars, Duncan is initially labeled a villain and is proud of it. In Saving Private Leechball, Chris switches him to the Heroic Hamsters, where he finds the kindness of his new team mates (particularly Zoey) is making his own heroic side overpower his "bad boy" image. The others find this amusing. It infuriates Duncan, however, to the point of taking drastic measures.
In Total Drama World Tour, Duncan and Alejandro don't have much interaction due to Duncan quitting the game in the very beginning. However, after Duncan returns, Alejandro isn't very pleased with that due to him knowing Duncan would be a threat. In The EX-Files, Duncan admits that Alejandro is "alright" because of him controlling Owen making him sing Take Me Out while doing the running man. As the game progresses, Duncan reveals that he doesn't fully trust Alejandro and attempts to get rid of him by turning Owen against him. Upon reaching the merge however, Duncan, who wanted to get rid of Courtney as soon as possible, align himself with Alejandro. Eventually, Alejandro betrays Duncan by teaming up with Heather and eliminates Duncan in African Lying Safari
Duncan and Beth are never seen interacting during Total Drama Island, since they are on opposing teams and Beth is eliminated rather early. During Total Drama Action, they are put on different teams once again and not much interaction happens between them until the merge. However, Beth transfer her hatred for Duncan's girlfriend to him and attempts to vote him off several times in order to spite her. When the both of them make it to the final two, their new friendship starts to bloom for the first time and the two are even shown helping one another make it to the finish line. Although Duncan and Beth seem to have a small rivalry in the last finale, it appears to two of them develop a respect to each other.
During the song, Blainerific, Duncan states she is "so, so horrific." In Hawaiian Style, Duncan laughs at Blaineley when Geoff shows a video of her crashing into a roof of a house after taking the Drop of Shame. He also says that Blaineley has so much in common with Heather while giving her a Team Heather flag, possibly referring to a lack of support for both of them.
Duncan's mean nature have made Bridgette hated him. Similarly, Duncan doesn't like Bridgette for distracting Geoff such as in Brunch of Disgustingness when the contestants are split into boys and girls. After forming the guys' alliance, Duncan orchestrates Bridgette's elimination, seeing her as the biggest threat. Upon hearing this, Bridgette also plans to eliminate him but without help from Heather, Bridgette is eliminated instead. In Total Drama Action, Bridgette make fun of him, along with Geoff and the other commentators during the first Aftermath show, seeing him as the main factor of Trent's failing relationship with Gwen.
In Saving Private Leechball, Duncan notices that Cameron is targeting Gwen from behind and quickly uses himself to protect her from Cameron's shot.
In You Regatta Be Kidding Me, Cameron, Duncan, Scott and Zoey are all on the same raft for the challenge after Mike (Mal in reality) broke the remaining boats. When Cameron came up with a plan to make their raft faster (which involved using Scott to lure Fang into pulling the raft), Duncan compliments him on it. However, in an earlier confessional, Duncan shows a little jealousy at Cameron, as even he can be a better villain than him.
Due to Chef Hatchet's militaristic nature and Duncan's delinquent persona, Duncan quickly began to get on Chef's nerves. During Basic Straining, he finds various methods to get through Chef's challenges, but makes sure to annoy Chef on the way. This is repeated in all episodes in which Chef is put in charge of the challenges, notably in Hide and Be Sneaky and Are We There Yeti?. During the hiding challenge, Chef Hatchet had no trouble finding Duncan after finding clues to where he was. During Total Drama Action, he argues with Duncan over who should do what in the challenge in Riot On Set and The Sand Witch Project, even though he wasn't supposed to interfere with either team.
Although the conflict between Duncan and Chris is relatively minor during the first two seasons, it quickly escalates in Total Drama World Tour when Duncan quits in the first episode after becoming frustrated with several factors. After taking the Drop of Shame, Duncan was reported missing and Chris take drastic measurements to find him including sending giant Drama Machines. Eventually, Chris found out that Duncan had been hiding in London and he was brought back to the competition by both his love interests. Once he was brought back into the show, Chris punished Duncan for quitting (and claimed he "owes him camera time") by making him sing every time he opens his mouth in Greece's Pieces. With the drama between Duncan, Gwen and Courtney going on, Chris decided to make Duncan stay in the game a little longer by pushing an intern off the plane even though Duncan received the most votes. In the next season, Duncan was brought back in Grand Chef Auto to demonstrate the challenge to the new contestants as well as to payback the remaining camera time he still owes him. However, Duncan escapes and later destroy Mt. Chrismore. In Total Drama All-Stars, Chris kept making fun of Duncan's recent change of personality after he was transferred to the Heroic Hamsters. In retaliation, Duncan destroys Chris' mansion, prompting Chris to call the authorities to arrest Duncan and therefore, eliminating him from the season.
Prior to Total Drama World Tour, the interaction between the two has been minimal, with merely a couple small bits of fluster between the two. However, the two become fierce opponents after Duncan kisses Gwen, whom Cody has been obsessed with since the first season in I See London.... This led to Cody harassing Duncan several times in Picnic at Hanging Dork until Duncan retaliates by throwing a dingo at him during the final challenge. Unknowingly, their conflict had indirectly lead to Gwen's elimination. Despite their conflict, Duncan chose to support Cody in the finale over Heather or Alejandro.
Since the beginning of the series, Duncan and Courtney share a love/hate relationship with each other. Although she kept complaining about Duncan's lifestyle, Courtney is shown to have feelings for him but denies it whenever someone ask. After having some alone time together, the two share their first kiss and officially becomes a couple. However, their time together was short and Courtney was eliminated not long afterwards and they do not meet again until Duncan was eliminated. They were also separated for the next season as Duncan was one of those who qualifies while Courtney doesn't.
Despite their relationship, tension rises when Courtney makes her debut midway in the second season after successfully suing the show as well having many unfair disadvantages. Additionally, Courtney was jealous of Duncan's friendship with Gwen and ruthlessly defeats him in many challenges. Nevertheless, the two of them still have feelings for each other though Duncan is losing his patience. After a night discussing about their relationship, Courtney decides to give Duncan a second chance provided he memorize and correct everything she listed about him on a thirty-two page letter. Tired of Courtney bossing him around, Duncan voted her off in Top Dog and they broke up. Despite this, the two of them eventually reconcile after the finale.
In Total Drama World Tour, Duncan and Courtney are still in a relationship but he beginning to shift his feelings to Gwen instead after becoming tired Courtney bossing him around. After Duncan returns, he and Gwen share a kiss and Courtney eventually found out about the affair and broke up with him. For the remainder of the season, the two of them argue with each other every time they were in close proximity to each other. Determine to eliminate her, Duncan gains the help of Alejandro and successfully eliminate her in Chinese Fake-Out.
Two seasons later, Duncan's conflict with Courtney continues while she pretends that he didn't exist at all. After Gwen dumped Duncan, both of his ex-girlfriends constantly make fun of him and refuse to listen to even when he tries to warn them about Mike being not as kind as he appears to be.
Despite their contrasting personalities, Duncan and DJ become friends in Total Drama Island, after Duncan defends DJ when their team needs to vote off someone and DJ being one of the prime candidates due to his lack of participation in the challenge. The two are joined by Geoff and are often seen hanging out together. Later on in the season, the three of them form the first guy's alliance with Owen when they realize that the girls outnumbered them. In the next season, Duncan and DJ are on the same team again after they are selected by Gwen. DJ is impressed by Duncan's performance throughout the season, especially when he replaces Gwen as their team's unofficial leader after Gwen is eliminated in The Chefshank Redemption. However, DJ chooses to vote for Beth to win the million dollars in The Aftermath: IV.
During Total Drama Island and Total Drama Action, Eva and Duncan had had numerous changes with their friendship-hatred towards each other. During The Big Sleep, Eva accuses everyone of voting her off and plans on getting revenge, without even knowing if everyone (including Duncan) actually voted for her. Around the beginning of No Pain, No Game, Chris tells Duncan and the other ten remaining campers that she and Izzy would return to the island. Hatred between the two is seen even more when Duncan is seen looking scared upon her arrival, as well as Eva saying that she will get revenge on her "backstabbing Bass team who voted her off.” Duncan shows even more conflict towards Eva when he chants with the rest of the group her name for Bridgette to choose her to go into a crate with Sasquatchanakwa for ten seconds. Although, it should be noted, that he is one of the only people not to vote Eva off, instead he voted for Heather however he can be seen smirking at her after when Chris when revealed the contestants confessionals to everyone and in Haute Camp-ture, Eva admits that she likes Duncan's "style" when talking about the dodge ball challenge in Dodgebrawl. In the first Aftermath, Eva is seen to be against Duncan "breaking up" the relationship between Gwen and Trent. She is however pleased when he won Total Drama Action.Total Drama World Tour and not competing on Total Drama Action, but when the Bass had to face their first elimination ceremony, and all the girls were glaring angrily at Ezekiel, Duncan told Ezekiel that he had "a lot to learn about the real world."
In Celebrity Manhunt's Total Drama Action Reunion Special, Duncan says that he could survive in the streets, to which Ezekiel replies that he could survive as well (as he is getting his wallet stolen by a hobo).
When Ezekiel was eliminated in Walk Like An Egyptian - Part 2, Duncan simply whistled and said, "sucks to be Zeke.”
In African Lying Safari, when Duncan and Alejandro found themselves stuck in quicksand, the latter managed to trick Ezekiel into grabbing a stick Alejandro was holding and pull them out, saving both of their lives. However, Duncan was later tricked by Alejandro into getting attacked by the newly-feral and rabid Ezekiel. While Duncan was washing some red berries off of himself at a small pond, Ezekiel burst out of the water and slashed Duncan across the chest, then pounced on him and beat him savagely. This eventually caused Duncan's elimination.
Duncan and Geoff's friendship always strayed in certain points. During Brunch of Disgustingness, Geoff (on the male team) helps Bridgette (on the female team) in one of the mini-challenges, which caused his team to lose the point for that mini-challenge. This got Duncan furious, however, they immediately made up after Chris' interjection, much to Bridgette's surprise. At the end of Hide and Be Sneaky, Duncan finds out that Geoff didn't stay loyal to the Guy's Alliance by voting Bridgette off (even though she did leave without his help). Geoff was then seen saying good night to the rest of the boys outside the cabin, upside down, hanging from a tree. To Duncan, this disloyalty (as well as his all-around niceness) caused him to be voted off later in Trial by Tri-Armed Triathlon. In the next season, Geoff only made it to the second episode, when he and Bridgette were kicked off in Alien Resurr-eggtion. As Bridgette is clueless to why they were kicked off, Duncan tells them both that the remaining cast members used to like them, but now that they began to make out so much, the likeliness has gone.
Gwen is shown to have a love/hate relationship with Duncan throughout Total Drama Island: though they develop a camaraderie, there are times where Gwen wants him off the island, even choosing to try and eliminate him in Hide and Be Sneaky with the other girls, and not considering him one of the good people during her final rant in The Very Last Episode, Really!. Even with these instances, during the second season, the contact between Gwen and Duncan has often been misinterpreted by the other contestants as a couple, causing tension and jealousy by their respective love partners.
The pair begins to have feelings for each other in Total Drama World Tour and share their first kiss after Duncan returns to the competition in I See London.... They finally become a couple after they share another kiss in The EX-Files and after Courtney broke up with Duncan earlier in the episode, though their time together was short as Gwen was eliminated in the next episode. They are finally reunited after Duncan was eliminated again five episodes later.
However, their relationship is over two seasons later in Moon Madness when Gwen becomes jealous and angry that Duncan was constantly showing interest toward his ex-girlfriend Courtney, which results in Gwen dumping him. Duncan isn't heart broken at being dump by her and would still attempt to warn Gwen about Mike being not what he seems. However, with both his exes being good friends now, Gwen refuses to heed his warning and occasionally mocks him.
Harold has a long history of conflict with Duncan which started in the first episode of the series. Throughout Total Drama Island, Duncan frequently pick on Harold by pulling several pranks on him. Harold will eventually retaliates by rigging the elimination votes in Basic Straining and caused Courtney's elimination. Duncan eventually find this out and their conflict becoming more and more intense in Total Drama Action. Being the final male members of their team however, the two of them are often paired with each other during challenges, frequently leading to their team's victory. Eventually Duncan and Harold make a truce and temporarily end their conflict, but this is spoiled by Owen's interference and their conflict resumes. Their conflict is yet unresolved, but it uncertain where they currently stand due to having very little interaction after this event.
From the moment they met, Duncan immediately shows attraction towards Heather. He was very well known to sarcastically call Heather by pet names in Total Drama Island. while she calls him names based on his juvenile record in the next season. Despite this, Duncan, like most contestants, hated Heather's cruel nature.
Duncan agrees with everyone about Izzy's usual nature, classified as pure insanity. However, he didn't seem to have a conflict with her and the two are very similar in nature. In Search and Do Not Destroy, Duncan appears to be worried when he saw a snake wrapped around her head and bite her. Izzy is heard saying "Woo-hoo! Way to go Duncan." in Hook, Line, and Screamer when he found out who was the psycho killer behind the mask and removed it. In Wawanakwa Gone Wild!, Duncan found Izzy's "sharp-shooting" tranquilizer skills very amusing when a tranquilizer dart was shot in Heather's butt. Because of being in a temporary alliance with Heather, he and Heather voted Izzy off the island that episode. In Mutiny on the Soundstage Duncan calls Izzy a freak when he could not remember who Izzy was reincarnated. Izzy was impressed with Duncan's break dancing skills in The Aftermath: IV. However, Izzy voted for her alter-ego (Explosivo) to win the million dollars. Although she did smile when Duncan was announced the winner in his ending.
Both are placed on the same team in Total Drama All-Stars, and are seen to be on friendly terms in Heroes vs. Villains, after she warns him that she'll be running the team. He laughs when she points a pun on his name, after his key doesn't work. At the Campfire Ceremony, they give each other high-five after Chris announces their win. In Evil Dread, Duncan seems annoyed by Jo's bossy attitude, leading to be confused whether to vote her out or Lightning. In Saving Private Leechball, Duncan was annoyed that Jo, Heather and Alejandro kept on arguing throughout the challenge, knowing that they were actually trying to get him and his girlfriend to form an alliance with one of them. After their team lost, Duncan most probably voted for Jo as she cost them the challenge for shooting Scott with their own cannon.
Duncan and Justin had no connection with each other on Total Drama Island, as they were on separate teams. Duncan did, however stare at him in Not So Happy Campers - Part 1 with the rest of the campers. In Total Drama Action, they seemed to get along with each other when they interacted in the guys' trailer though Duncan became annoyed when Justin refused to help him open the trailer door in The Chefshank Redemption because Justin was afraid that he'd ruin his manicure if he tried to help. In Super Hero-ld, Justin convinces Duncan and Harold to start a new guys' alliance in order to vote off one of the four remaining girls since they were outnumbered by them. Duncan and Harold agreed to join him.
However, any camaraderie Duncan and Justin had went out the window in The Princess Pride. At the beginning of the episode, Duncan misleads Justin in the first part of the challenge as a prank, getting Justin hurt (which Duncan laughs at). Then, Justin spots Duncan cheating in the same challenge, but Chris does not believe him. After that, Justin begins to fall for Courtney, much to Duncan's jealousy and anger as he still have lingering feelings for Courtney. They continue to get into arguments over Courtney, mostly resulting from Duncan's jealousy that Courtney seems to be responding favorably to Justin's flirting. At the end of the episode Justin is eliminated and Duncan, other than bidding him farewell in a sarcastic tone, doesn't seem to be upset with his elimination, along with the other contestants. In The Aftermath: IV, Chris showed that Duncan was nice to Justin once by fixing Justin's sleep mask while he slept. In order to get on Justin's good side, Duncan tells him that he still have his still had his good looks during Justin's questions. However, Justin voted for Beth.
Like many of the other contestants, Duncan does not take Katie or Sadie seriously due to their bubbly and rather ditzy personalities.They both appear to be somewhat afraid of him, as they are shown to be hesitant when Courtney asks who is going to wake Duncan up during the episode, Dodgebrawl.
In The Sucky Outdoors, both girls get separated from the rest of their team. Duncan is one of the first to notice this and asks everyone if they have seen "Tweedle-Dum and Tweedle-Idiot." Later, after Courtney suggests that the two might have been eaten by a bear, Duncan agrees with her and sarcastically says, "Darn shame." Sadie frowns when Duncan picks her and Harold as canoe partners in Up the Creek and in Who Can You Trust?, Sadie regards Duncan, along with the rest of the team as "marshmallow-eating freaks."
Although she dislikes him for being a mean and untrustworthy person early on in Total Drama Island, Leshawna is one of the first people who is aware that Duncan is more than just a tough guy. When the two are paired in Trial by Tri-Armed Triathlon, they easily gets on each other nerves, frequently arguing on who should do what during the challenges. Eventually, Leshawna confronts Duncan that he is not as tough as he seems and reveals that she had an off-screen conversation with Courtney about the incident with DJ's bunny in Who Can You Trust?. Duncan finally admits about his hidden soft side and the two put their differences aside in order to focus on the challenge. Despite this, tension rises between the two in Total Drama Action when they were put on the same team with Harold and Leshawna had to frequently defends Harold from Duncan's bullying. At the same time, Leshawna tries to form an alliance with Duncan and Harold but the two of them refuses. After Gwen's elimination, Leshawna begins to have a little respect for Duncan as his leadership skills allows them to win many challenges. Eventually, Duncan begins to hate Leshawna even more as not only she fake cried in order to get the reward in One Flu Over the Cuckoos all for herself, she also badmouthed everyone, mocking Duncan for being soft when he is around Courtney. Although he is mad, Duncan forgive her and let her stay in the competition a little longer. After the merge, Leshawna successfully convince both Duncan and Harold to form an alliance with her but seeing how big of a threat Courtney is, Leshawna agrees to team up with Lindsay and Beth to eliminate Duncan in order to make Courtney mad. However, the plan fails when Leshawna herself was eliminated by the Guys Alliance and Courtney.
In Evil Dread, Duncan states that he opted to vote for Lightning or Jo, finding both of them annoying, but couldn't decide on who. It is imply that he finally decided to vote off Lightning as he is the reason their team lost the challenge.
For most of the series, Duncan and Lindsay appears to have a minor conflict although this is mostly because of Lindsay transferring her hatred towards his first girlfriend to Duncan. In Not So Happy Campers - Part 1, Duncan is briefly seen with his arm around Lindsay. While she appears to be scared, she doesn't say anything. In X-Treme Torture, Duncan and Lindsay were paired up in the final challenge. Duncan was furious that he failed to make Lindsay lose the challenge which leads to a Screaming Gophers victory. He is so angered by this he nearly attacks Chris, to force him in giving his marshmallow. In Brunch of Disgustingness, Chris explains that the challenge will be a regular "Battle of the Sexes.” Duncan gives emphasis to the word "sexes" towards Lindsay by winking at her. She responded by sticking her tongue out at him. In That's Off the Chain!, Duncan was seen to be annoyed at DJ and Owen talking to Lindsay. When Duncan needs to ride Lindsay's bike, he disapproves of it due to its girly nature but ultimately does it and even compliments her for making a fast bike. Duncan backed up Lindsay when she discovers Heather's betrayal, saying that it was "cold.” He seemed arguably sad at the Dock of Shame this episode, and smiled a tad when Lindsay said goodbye to him. However, during Haute Camp-ture, Lindsay calls him cruel and claims to hate his treatment towards deer and trees.Lindsay joined Beth and Leshawna to voted Duncan off in Super Hero-ld, but they failed due to The Second Guys Alliance, and Leshawna was eliminated instead. Also, in The Princess Pride, Duncan makes fun of Lindsay's large feet, calling Lindsay "Big Foot," which upset her. In Get a Clue, Lindsay handcuffs Duncan when she, Harold and Beth think he is the murderer. However, Lindsay eventually finds out that Duncan was innocent and apologized to him for accusing him. She then makes up for her mistake and brings him to the movies with her. Although they found it hard to talk at all due to their obvious differences, they both took pleasure in torturing Courtney and making her jealous.
In Rock n' Rule, Lindsay devised a plan to vote off Duncan along with Beth, Harold and Owen. Unfortunately, she got distracted by Beth when she looked at her and accidentally voted herself off, leaving Duncan safe. When the video shows Lindsay voting for herself after it was revealed that she got sent home, Duncan laughs rudely at her mistake, and does not seem upset.
According to Duncan, he knew Mike, who was known as Mal at the time, from juvenile hall when he was first incarcerated. Knowing how dangerous Mal is, Duncan stays away from him. Because of this, Mike does not recognize Duncan when they met in Total Drama All-Stars. After Duncan was transferred to the same team with Mike, Duncan initially doesn't remember Mike, but over time, he begins to recognize Mike's voice and finally remembers that he is Mal after listening to his whistling. For the next few episodes, Duncan tries to tell the other contestants, but his efforts are mostly futile, with only Zoey believing him.
This conflict first begins in Not So Happy Campers - Part 1, when Duncan makes a remark about Noah's mother, prompting Noah to sarcastically remark on Duncan's piercings. Duncan then grabs Noah's lip and threatens to pierce it, to which Noah calmly requests that he let go. Duncan obliges and Noah thanks him sarcastically. During Total Drama, Drama, Drama, Drama Island, Duncan and Courtney pair up, but also split up after Duncan "sprains" his ankle. After Courtney takes the case and leaves him, Izzy literally drops on her. Once Izzy takes the case, Eva passes Duncan and catches up to Izzy, though Noah stops at Duncan to talk to him about how he just became "less of a man" after Courtney turns on him. This enrages Duncan and forces him to try and "get" him, but only ends up taking his pants.
In The Aftermath: IV when it is revealed that Duncan wins the money, Noah is seen with an unsatisfied look on his face. In Beth's ending, he is seen cheering with Beth. Duncan, along with Gwen and Cody, laugh at Noah when they found out he is Chris' assistant in Celebrity Manhunt's Total Drama Action Reunion Special.
In I See London..., Duncan votes off Noah as soon as he returned to the competition. In Sweden Sour, Duncan uses Noah's absence as a strategy to get Owen on his side. Duncan tells Owen that they should honor Noah's parting words by allying together against Alejandro. He later asks Owen, "What would Noah do?" in order to get Owen to fully turn against Alejandro.
Along with Heather, Duncan is one of the main people to criticize Owen over his weight and/or consumption habits. This include Duncan forcing Owen to join the Guys' Alliance by dangling him over a short cliff. Despite this, there are many instances where they get along well. Duncan would go on to support Owen in the finale of Total Drama Island while Owen does the same in Total Drama Action. When Duncan returns to the competition in Total Drama World Tour, Owen is one of the few contestants remaining who isn't mad at Duncan for kissing Gwen. Duncan would later warn Owen not to trust Alejandro, using Noah's last words to encourage him. Although Duncan apparently vote off Owen later on, he admits that he misses him as he lost a valuable ally.
Sam and the rest of the team threw a surprise party for Duncan in Food Fright after he was added to the team in the previous episode. When Sam suggests that they sing the "Welcome Song", Duncan strongly disagrees. During the challenge, Duncan is seen cheering for Sam though he immediately denies it.
Through their limited interactions in Total Drama All-Stars, Duncan and Scott appear to get along.
In Heroes vs. Villains, Duncan and Lightning are attempting to talk Scott into jumping off the cliff to get the key for the McLean Spa Hotel. Lightning manages to pry Scott off the rock he was holding to, but ended up pushing the Robot off instead. In Evil Dread, Duncan and Scott are seen sitting next to each other in the McLean Spa Hotel, toasting to their villain status. In Saving Private Leechball, Duncan reveals that he has a liking to Scott, finding his clumsiness amusing. However during the challenge they are seen arguing over who gets the cannon. In No One Eggspects The Spanish Opposition, Duncan laughs at Scott when he falls to the ground in an attempt to appear villainous, but still ends up helping him up, causing Scott to thank him, much to Duncan's dismay.
In You Regatta Be Kidding Me, Duncan and Scott join Cameron and Zoey's team after Mal's mischief leaves them without another way to participate in the challenge. The former later goes along with Cameron's plan to use Scott as bait for Fang, in order to give their raft a "motor." Duncan even calls the shark to them, laughing as he does. Scott yells back angrily at Duncan in response, yelling that it's not funny for him.
While the two of them have little interaction early on in Total Drama World Tour, Sierra apparently dislikes though this is mainly because of Cody hating Duncan as well. In Celebrity Manhunt's Total Drama Action Reunion Special, Duncan and Courtney coldly respond to Sierra's friendly greeting when she attempts to interview them.
In Greece's Pieces, Sierra was thrilled when Cody punched Duncan and was talking about how Cody's fans would go crazy in excitement. In African Lying Safari, she refused to make an alliance with Duncan, possibly because of a certain conflict which may have made her look at him as a threat. In a deleted clip, Duncan mention he is glad to be away from Sierra while taking the Drop of Shame. Sierra also mentions her belief that Duncan has had feelings for Gwen since season one.
In Food Fright, the two become teammates after Duncan switches teams with Courtney. Sierra and the others host a surprise welcome party for him the next episode. Excited that Duncan was now on the Heroic Hamsters, Sierra quickly goes to get her smartphone for a photo, only to find out someone broke it. In No One Eggspects The Spanish Opposition, Sierra asks Duncan if they could search for eggs together and if she can call him Cody, but he turns down her offer as he was trying to assert his villainous status at the time. In Suckers Punched, Duncan finds her Gwuncan blog amusing and tells her to continue making them before she took the Flush of Shame.
These two didn't have much any conflict with each other in the first season, and even a friendship after (and possibly before) the merge. However, Trent's jealousy and believing that Duncan is stealing Gwen from him, drove them to become partial enemies during the early episodes of the second season. However by the third season, the conflict seems to be resolved and Trent seems to accept the fact Duncan is dating Gwen.
While the two of them appear to be friends in Camp TV, however, Duncan and Tyler don't get along in the actual series. In Not So Happy Campers - Part 1, Tyler was shown to be against sharing a cabin with Duncan, and took credit for Duncan's extermination of a cockroach, claiming he could do that as well to impress Lindsay. Duncan then mutters that girls like Lindsay "always go for the jocks.” Also, in Not So Happy Campers - Part 2, Duncan and Tyler are seen fighting over a hammer. Later in the episode, Duncan defends Tyler when Courtney suggests that the team vote him off instead of her. In Dodgebrawl, Tyler is shown to fear Duncan when the latter tells him he better not be woken up, and he gulps and has a look of fear. In Phobia Factor, even though Tyler gives support to Duncan while he tries to overcome his fear, Duncan mocks Tyler's fear of chickens when he was leaving for the loser boat.
In Greece's Pieces, Duncan angrily says in the confessional that he knows that Tyler saw him and Gwen kissing in the previous episode and threatens that Tyler should know better. He glares at him in economy class, knowing that Tyler is considering saying something about the incident. After being persuaded by Alejandro, Tyler told everyone about Duncan's secret. In The EX-Files, after Duncan is recovering from being kicked in the groin by Courtney, Tyler complains about Duncan to Alejandro and Owen, calling him a jerk and that saying that he'd never cheat on Lindsay the way Duncan cheated on Courtney, even adding that Duncan deserved two kicks to the groin instead of just one for what he had done. However, Tyler admires Duncan, as he is able to win the hearts of two hotties. When Duncan arrived to save Alejandro and Tyler from the aliens, Duncan punched Tyler's face to destroy one of the aliens. Duncan is later partially responsible for getting Tyler eliminated, where he and Alejandro had plotted together to vote him off.
After Duncan moved to the Heroic Hamsters in Saving Private Leechball, he immediately distrusts his new team as he believes they are out to get him. Additionally, he believes that the team's niceness is rubbing on him, making him act nicer than he normally would and also ruining his "bad boy" reputation. However, Duncan easily warm up to the rest of his team, notably Zoey who knows that despite his criminal history and his "tough guy talk" he is actually a nice person.
When Duncan discovers an old foe from juvie is on his team, he quickly shares this information with Zoey, who is closer to Mike than anyone else. She is also the only person who believes Duncan as everyone else either ignores him or mocks him when he tries to advise them.
- Despite his conflicts, he makes it to the final five in the first three seasons and is even a finalist in Total Drama Action, where the eliminated contestants chose him as their favored to win in one of the endings.
- Despite his rude and harsh attitude towards the other contestants, Duncan actually has a well-hidden soft side.
