Dissonant Serenity: Chris' all-purpose facial expression is a bland smile, very likely rehearsed. He can remain serene in almost any situation because he doesn't really care what happens to the contestants.
Even Evil Has Standards: When Duncan facetiously suggests that Chris is having the eliminated contestants slaughtered for meat, after having previously suggested that the notoriously cheap producers were using the interns killed on the job for that purpose, Courtney insists that there are some things even Chris wouldn't do.
Evil Laugh: Chris occasionally indulges in hammy "evil stage laughter".
Executive Meddling: Although this is a canon trait in-universe for Chris, the reimagined version tends to meddle more subtly than his canon counterpart (who was, after all, satirizing such things at the meta level).
When Noah refuses to do the cliff diving challenge and gives Chris too much lip about it, Chris decides to make an example of Noah. The trope in this case is subverted when Noah later changes his mind for unrelated reasons and (successfully) dives after all, leaving Chris visibly disappointed.
When an elimination vote ends in a tie, Chris effectively casts the tiebreaking vote himself in an unusually transparent (and, arguably, reasonable) example of meddling.
Large Ham: When he’s not looking serene, Chris tends to say and do things “theatrically”. (He is a professional actor, after all.)
Stepford Smiler: Related to Dissonant Serenity above. Once the contestants see Chris' callous disregard for human life, it doesn't take them long to get sick of his ubiquitous bland smile. Courtney is described as wanting to push Chris' face in because of that smile, and her reaction is fairly typical.
Chef Hatchet, Chris' aide
Punch Clock Villain: Although Chef does his job (which frequently involves making the contestants' lives more difficult) in a conscientious and workmanlike fashion, he'll also help the contestants out from time to time if it doesn't conflict with his duties. He agrees to conduct the funeral service when Chris can't be bothered, and his attitude toward Sadie after her ordeal during the camping challenge could even be seen as kindly.
Alejandro, an intern. Also called "the former reality show star".
Big Brother Mentor: During the first challenge, Alejandro gives Beth an Info Dump on elimination game strategy. A remark after the talent show implies that they have since become close, implying that Alejandro is mentoring Beth on an ongoing basis.
Draco in Leather Pants: There is (so far, anyway) no sign of his canon manipulativeness, justified in-universe by the fact that he's a mere working stiff, not a contestant, so he has no incentive to manipulate people. His status as the former dominating antagonist of a failed elimination game show suggests that his canon traits are still there, but he hasn’t shown them and they come across as informed attributes.
Mauve Shirt: Although other interns have lines, Alejandro is by far the most prominent and has a major scene with Beth during the first challenge.
Beth, the wannabe. Also called "the nerd girl" and "the farm girl".
Odd Friendship: Seems to be forming one with the manic, arguably psychotic Izzy, starting when they discover that they have the same talent (twirling fire batons) and perform together in the talent show. As Izzy puts it, "Twice the fire, twice the fun."
Bridgette, the surfer chick
Jade-Colored Glasses: Partway through the confessional spot wherein she denounces Chris for his treatment of the interns, Bridgette begins to speak in "the disillusioned tone of one who has lost too much innocence before her time."
Oh My Gods!: Bridgette says "oh, gods" in situations where other characters might say "gosh", "oh my god", etc, suggesting that she subscribes to a polytheistic (and probably naturalistic) religion.
The Storyteller: There were some real horrors still ahead of us, not to mention the backstabbing and double dealing that elimination games encourage, and she was such a pure-hearted girl. I hate to think what getting deep into the game could have done to her.
Mr. Vice Guy: He's loyal and well-meaning, but his jealousy issues enable Heather to manipulate him. He also seems at times to have a one-track mind.
Shipper on Deck: One of the reasons that Cody and Noah ally with each other is to help get them hooked up with the girls that they're crushing on.
Silent Scapegoat: When Gwen mistakenly believes that Cody, and not Heather, was the instigator of an incident that badly hurt Gwen, Cody does not correct her because he is unwilling to badmouth a girl.
Twin Threesome Fantasy: Cody clearly has one for Katie and Sadie, as the only "twins" on the island, although he seems content to let it remain a fantasy.
Courtney, the Ms. Do-It-All. Also called “the former CIT” (after her iconic CIT experience is revealed), "the lawyer-to-be", "the diminutive dynamo", etc.
Friendly Enemy: To Heather. Their positions as the leaders of their respective teams makes them natural rivals, and they don’t appear to be friends, but they get along reasonably well. When they trash talk each other, it tends to be with tongue in cheek.
Good Angel, Bad Angel: In a real-person variant, Courtney, who is trying to re-educate Ezekiel to be acceptable to polite society, is Ezekiel's "good" angel. Duncan, who is arguably a bigger sexist than Ezekiel and tends to view girls as objects, is his "bad" angel. Both are Ezekiel's friends and try to pull him in opposite directions, sometimes with Ezekiel actually sitting between them.
The Napoleon: The Storyteller and other contestants occasionally cast Courtney in this light, although it's questionable how well it really fits Courtney's disposition. In the original, Courtney sometimes looks short and sometimes not; but in the reimagining, she is explicitly tiny.
Ezekiel: I just realized that we’ve been spending most of this game doing favors for each other, eh?
Courtney: That’s how people get to be friends. That’s how alliances are born.
Team Mom: Courtney is a good deal more successful at this than her canon counterpart, earning not only deference but also respect from most of her teammates—even Ezekiel. Especially Ezekiel.
Izzy: Guys, you know what Zeke thinks of girls, and we can just imagine what he thinks of girls being in charge. And yet he was the first one to stick up for Courtney. That should tell you something.
D.J., the soft-hearted brickhouse. Also called "the gentle giant".
Animal Wrongs Group: In the first challenge, part of the reason D.J. refuses to dive into shark-infested waters is because he couldn't bear to hurt the sharks, which he might have to do if he were to miss the safe zone and have to defend himself.
Duncan, the juvenile delinquent. Also called "the Juvenile Hall alumnus" and "the scorner of laws".
Every Scar Has A Story: When Duncan removes his shirt for the first time in the presence of the other boys, they notice that his arms are covered with scars. They ask how he got them, and he explains quite matter-of-factly that he got them knife fighting.
Duncan: Let me tell you something. If you’re in a knife fight, and you get out of it without getting cut, that doesn’t mean you’re good. It means you’re lucky.
One scar is different, and Duncan explains when asked that it came from a broken bottle.
Scars Are Forever: The long sleeves on Duncan's shirt conceal the fact that his arms are covered with knife fighting scars.
Eva, the musclegirl. Also called "the steel maiden" "Iron Woman", etc.
Combat Pragmatist: During the dodgeball match, Eva routinely throws at the groins of both male and female opponents—not because she's trying to hurt them, but rather because it's a difficult spot to defend well under dodgeball rules.
Homeschooled Kids: Lampshaded by Ezekiel when he arrives on the island. He points out that "just because I'm homeschooled doesn't mean I live in a cave", in the process defying the canon version of his introduction. Ezekiel also points out that he has Internet access at home, even if "it's just dial-up".
Innocent Bigot: Courtney depicts Ezekiel in this light when she argues that he doesn't deserve to be voted off just for being a sexist.
OC Standin: The reimagining replaces social ineptness with religiosity as a basic aspect of Ezekiel's character because (a) social ineptness is an aspect of the homeschooled stereotype that that author considers unworthy of perpetuation; (b) most parents who homeschool their children do so for religious reasons; and (c) the canon describes Ezekiel’s parents as “freaky prairie people”, which the author interprets as code for “Bible thumpers”. This change effectively makes Ezekiel a new character. Although Ezekiel remains a sexist because he wouldn't be Ezekiel without it, his sexism is more subdued and realistic than in the original.
Whip It Good: Ezekiel cracks a mean bullwhip, as he demonstrates during the talent show.
Geoff, the urban cowboy. Also called "the party king".
You Are Better Than You Think You Are: When Gwen is pining for her lost boyfriend, Leshawna tells her in pertinent part that she's stronger than she thinks she is, and that if she just tries, she'll be better at making friends than she thinks she is.
Always Someone Better: Although Heather dominates her team, she just can't seem to win an argument with Noah. She does once (sort of) by beaning him with a football, but philosophers frown on such crass methods of discourse.
Anti-Villain: Although Heather behaves much as she did in the canon season being reimagined, the reimagining explicitly depicts her as being a basically decent person when push comes to shove. She sees herself as merely a genre-savvy player doing what she thinks the rules encourage. What makes her an anti-villain and not merely a designated villain is that she seems to enjoy her antagonistic role a little too much for a mere designated villain, not to mention the way she treats her allies.
Dragon Lady: The Storyteller invokes this trope by using "dragon girl" (a juvenile equivalent of "dragon lady") as one of her standard descriptive phrases for Heather, who is ethnically Asian or half-Asian and who retains her canon personality.
False Friend: to Leshawna. Heather goes so far as to actively help Leshawna out during the Awake-a-thon, and Leshawna does not see Heather's true colors until the Diary Incident. Contrast to the canon version, where Heather's false friendship is never mentioned again after her initial reconciliation with Leshawna.
Shipper on Deck: Heather exploits this trope in that she's only shipping Cody/Gwen, however aggressively, to manipulate Cody and annoy Gwen. She doesn't actually want them to hook up.
Izzy, the psycho hosebeast. Also called "the demented redhead", "Weird Red", etc.
Big Eater: Presumably the high metabolism type, considering how manic she is. At the buffet before the Awake-a-thon, Izzy matched Owen almost bite for bite, but eventually barfed because she couldn't keep that much down.
Imaginary Friend: Izzy has a (presumably) imaginary friend named Sunshine. Nothing is currently known about Sunshine except that she is female and is supposedly hot for Duncan.
Odd Friendship: Seems to be forming one with Beth, a shy farm girl. See entry under "Beth".
Pyro Maniac: Although this is a canon trait for Izzy, the reimagining develops it more fully. She carries a large magnifying glass with her because "you never know when you might want to burn stuff", and she can wield it with great precision and artistry. At the other extreme, she's in hog heaven when an accident turns the amphitheater into an inferno.
Izzy: Did you see those huge flames? And the way all those flaming embers were popping out? It was like a real Fourth of July down in the States.
Justin, The Embodiment of Manly Beauty. Also called "The Incredible Hunk" and "the uberhunk".
Comes Great Responsibility: Unlike his canon counterpart, who is not above using his looks to manipulate people, the reimagined Justin seems to have an "I must use my powers only for good" mindset.
Flat Character: Although Justin gets somewhat more development and a lot more screen time than in the original, he remains at his core a one-joke character.
Informed Attractiveness: Although Justin gets a lot of this in canon, it's even more pronounced in the reimagining. His and Lindsay's beauty is explicitly depicted as being virtually godlike. There’s a reason why one of Justin's standard descriptive labels is "The Embodiment of Manly Beauty". His and Lindsay's instantly falling for each other is mainly based on their amazement at finding someone else as beautiful as they.
Love at First Sight: With Lindsay, because Justin hadn’t thought that he would ever meet a girl as gorgeous as he. When they meet, Justin’s unspoken thoughts match Lindsay’s almost word for word.
Satellite Love Interest: Although Justin gets a lot more to do than in the original, his only real dramatic function is to be the incredibly gorgeous Lindsay's equally gorgeous love interest.
Katie, the strong BFF. Also called "the Thin Twin".
Big Eater: High-metabolism type. At the buffet before the Awake-a-thon, Katie ate so much that she would have barfed but for Justin's timely intervention. During the camping challenge, it comes to light that Katie has a "blast furnace metabolism" and eats more than Sadie, who weighs twice as much.
Katie routinely throws at the groins of both male and female opponents, just as Eva does—not because she's trying to hurt them, but rather because it's a difficult spot to defend well under dodgeball rules. Katie lacks Eva's intimidation factor, though, because she's not as strong.
When Eva challenges the Eagles to single combat, Katie prepares to throw at Eva from the crowd because, in the Storyteller’s words, "she was not learned in the customs of martial chivalry".
Conjoined Twins: The storyteller occasionally invokes this trope by referring to Katie and Sadie as "the Siamese Campers". They are not physically conjoined, but it often seems that they might as well be.
Crouching Moron, Hidden Badass: Katie and Sadie show what they’re capable of when they convince Chris to let them be on the same team. They also surprise people in the dodgeball match—separately, Katie is a fairly good player and Sadie is average at best even without her propensity to tire easily; but when they're on the court together, watch out!
Double Agent: When Katie apologizes to Gwen for helping Katie's ally Heather to humiliate her, Gwen’s price for forgiving Katie is that Katie must keep Gwen informed about what Heather is up to. Desperate for forgiveness, Katie agrees.
Finishing Each Other's Sentences: Katie and Sadie occasionally do this as a manifestation of their pseudo hive mind. These exchanges tend to be long and elaborate, sometimes with multiple speaker changes in the same sentence.
Girlish Pigtails: Katie and Sadie arrive on the island wearing their canonical pigtails, as befits their canonically childlike personalities. When they get makeovers that include ditching their pigtails for big hair, they look "five years older than they had the day before", according to the Storyteller. Noah further lampshades this by saying, "The kiddies have grown up." Shortly thereafter, the "grown up" Katie and Sadie get caught up in one of the story's most grimly dramatic adventures—just in time for Sadie's birthday.
Hive Mind: The Storyteller sometimes describes Katie and Sadie in exactly those words. Cody uses different words to the same effect when Katie and Sadie are “persuading” Chris to let them be on the same team:
Important Haircut: When Lindsay gets a new hairdo to make the best of a bad situation after her hair is severely damaged, Katie and Sadie ditch their little-girl pigtails to show solidarity with their stricken ally.
The Power of Friendship: During the first challenge, when Chris refuses again to let them be on the same team, Katie and Sadie gang up on him and force him to reconsider.
Wonder Twin Powers: Katie and Sadie display a realistic version in the dodgeball match. Separately, Katie is a fairly good player and Sadie is average at best; but the first time they're on the court together, they dominate in part because they are so attuned to each other that they can coordinate without speaking. They are so fearsome that when Duncan takes over as the Muskies' coach, he names Katie as a priority target if—and only if—she and Sadie are both on the court.
Genius Ditz: Lindsay is described thusly (the Storyteller’s exact words being “idiot savant”) during the phobia challenge, when she must give Sadie a bad haircut. The normally turnip-brained Lindsay is a knowledgeable and reliable source of beauty-related expertise, and uses this knowledge to exploit a loophole in her phobia test.
Owen, the big fat friendly guy. Also called "the gregarious gargantua", "the man-mountain", etc.
Fartillery: Owen accidentally gasses two teammates during the Awake-a-thon, causing them to fall unconscious.
Stout Strength: Although he's no slouch in the canon, the reimagined Owen is immensely strong—significantly stronger (and bigger) than his canon counterpart.
Sadie, the smart BFF. Also called "the butterball".
Adaptational Badass: Although still a whale, Sadie is tough, smart and effective, and was generally none of those things in the canon. The pseudo-canonical text bios on the show's website did at least say that she was supposed to be smart.
Acrofatic: Sadie is tougher and more nimble than she looks, although she does tire easily.
Breakout Character: Sadie got a significantly expanded role because early reader response to her portrayal was so enthusiastic.
I Cannot Self-Terminate: When Katie is dying and Sadie is reduced to praying to save her, Sadie asks that she be allowed to die if Katie does. (The circumstances are such that this might be a simple matter to arrange.) The implication is that, however much Sadie might want to die in such a case, she would not be able to go through with suicide.
Kevlard: The obese Sadie is a lot tougher than she looks (or realizes).
Tyler, the inept jock. Also called "the jock of all trades" and "Red Jock".
Brett, the TDI:Next Gen contestant-to-be
Disappeared Dad: Brett's mother has "neither spouse nor partner" according to the chapter-opening boilerplate. The reason why isn't revealed until the end.
The Watson: Brett asks a lot of questions that readers might be expected to ask, and the justification for the Storyteller's occasional aside comments is that they are directed to her son. Brett's questions also drive the Greek Chorus commentary between episodes.
No Name Given: Brett’s mother is identified as “The Storyteller” in the cast listing and simply as “Brett’s mother” in the story itself. She does reveal in the prologue that she had been a contestant on the first season of Total Drama Island, and that she "did pretty well, but didn't win". The author has stated that her identity will be revealed near the end, but that many or even most readers may have it figured out well before then, thanks to clues sprinkled throughout the story.
The Storyteller: The frame story consists of Brett's mother telling about her experience on Total Drama Island, in a series of interlinked stories.
That Man Is Dead: When Brett asks his mother why she refers to herself in the third person when telling her tale, she replies, "I was a different person then. You made me grow up before my time." She also cites this as part of the reason that she started going by her (unrevealed) middle name when she entered college.
Third-Person Person: Although Brett's mother refers to herself in the normal first-person in the frame story, she refers to herself exclusively in third person when telling the main story. When Brett asks why she does this, she explains that (a) she was a different person then; and (b) she simply thinks that it works better for the narrative because there are many scenes where she was not present. The real reason, of course, is to conceal her identity from the reader.
Gossipy Hen: The contestants have an in-joke wherein they hide information sources by saying "Sunshine told me" in the same way that an angry mother might say to her misbehaving child, “a little bird told me”. This has the side effect of painting Sunshine as an incorrigible gossip. The girl who created the Sunshine character did fanarts about this.
