The Terrible Tikis
- Dwindling Party: By the merge, they're reduced to only three contestants. Needless to say, they live up to their name.
Over Nine Thousand
- A House Divided: None of the contestants on this team really like each other and they all spend most of their time arguing, but they still somehow manage to win five challenges in a row.
- Springtime for Hitler: The team eventually gets so tired of winning and not voting anyone off that Chris outright states he's rigging the challenges so that Over Nine Thousand will lose, and they begin putting in minimal effort. Of course, they continue to win.
- Teeth-Clenched Teamwork: What helps them win all of said challenges.
Carson - The Funny Guy
Carson is a fairly average fellow who's... not particularly funny. The winner of Total Drama School, he was mostly known for coasting through the game due to being inoffensive, and his on-and-off relationship with Amanda.
- The Generic Guy: The more explosive characters in this season's cast showcase this even more.
- Demoted to Extra: After winning the prior season, he's an inconsequential pre-merge boot this time around.
- Straight Man: Plays this role on the Terrible Tikis.
Sharissa - The Psycho
Sharissa is the cousin of Izzy from Total Drama, and somehow manages to be even more bizarre. In School, she was the runner-up, and was known for her bizarre crush on Alex, her violent and hyperactive nature, and her tendency to appear and disappear at random.
- Ax-Crazy: This is Sharissa at her worst, though it's not as pronounced this season due to her being much less major.
- Cloud Cuckoo Lander: Sharissa is a bit... off.
- Composite Character: According to Word of God, Sharissa was meant to be a mixture of Izzy and Sierra from the canon series. She shares her off-beat nature and family blood with Izzy, and similar to Sierra, she's incredibly tall, has purple hair, and has an obsessive crush on a docile brown-haired boy.
- Demoted to Extra: Similar to Carson, Amanda, and Alex, Sharissa takes a back seat this season for the new characters.
- Genki Girl: Just like her cousin, she's got quite a bit of energy.
- It Runs in the Family: Considering she's basically exactly like Izzy (as well as Roz, her apparent other cousin from Total Drama Tokyo).
- Stalker with a Crush: To Alex, much to his chagrin (and occasional pleasure).
- Tiny Guy, Huge Girl: With Alex, once again. She's at least a foot taller than him.
Amanda - The Hot Antagonist
Amanda is... the antagonist. Or at least she was during School, where she manipulated multiple contestants including Carson and Extreme Doormat Veronica, and somehow slid to the final three despite everyone hating her.
- 0% Approval Rating: Literally everyone hates Amanda and doesn't even bother hiding it, even her boyfriend at certain points. This leads to her being voted off at her team's first elimination ceremony.
- Alpha Bitch: The earliest one of the series.
- Arch-Enemy: Meg is hers, thanks to a Noodle Incident in grade school.
- Demoted to Extra: Voted out in the third episode after making it to third place in the previous season.
- Technicolor Hair: Her hair has blonde and brown streaks, similar to a certain Rich Bitch from a couple stories after.
- Villain Decay: After spending the entirety of School as the main antagonist, this season Amanda becomes a laughingstock and is booted second.
Alex - The Lazy Bum
Alex is a small, chill guy who isn't the hugest fan of physical work. Despite this, he managed to make it to 4th place in School, and developed an adversarial but romantic relationship with Sharissa along the way.
- Deadpan Snarker: Not as pronounced as others, but he can be snarky.
- Demoted to Extra: After making it to the final four in School, he's possibly the most minor character of the whole story this time around - he doesn't actually show up until the second chapter, and is voted out in the fourth.
- Lazy Bum: His label. He's impressively lethargic, and spends most of the challenges sleeping.
- The Load: His lazy nature really doesn't do much to help out his team, and it's why he ends up eliminated early.
- Tiny Guy, Huge Girl: With Sharissa, he's often found on her shoulders.
Meg - The Female Jock
Meg, an athletic and cheery girl who's the captain of her local cross country team, is the 5th placer of School. During her time in the game, she adopted an unofficial leadership role on her team, the Killer Apples, and was the recipient of a massive crush courtesy of Gary.
- Action Girl: Thanks to her athletic skills.
- Deadpan Snarker: Meg's snarky side emerges this season after she's irritated enough by some of her teammates.
- Hair of Gold, Heart of Gold: Meg has light blonde hair and is probably the friendliest contestant on the cast.
- My Greatest Second Chance: Subverted - she's not quite Demoted to Extra, but she's voted off at the end of the pre-merge after being on the path to make it far again.
- Nice Girl: What eventually causes her to be viewed as a threat and voted off.
- Only Sane Woman: Adopts this role on Over Nine Thousand, and it doesn't get her anywhere, really.
- Passionate Sports Girl: Captain of her cross country team, and her personality fits the bill.
Gary - The Internerd
The canon's first Breakout Character, Gary came in 6th place in School thanks to his bromances with Devin and Carson and his massive crush on Meg. He's a big fan of referencing outdated Internet memes, especially those of the Dragon Ball Z variety.
- Adorkable: Gary has his moments where he goes full-on with this, especially his interactions with Meg.
- All Love Is Unrequited: Harbors a massive, unrequited crush on Meg that she's well aware of but won't reciprocate.
- Catchphrase: "It's over 9000!"... which he actually names his team.
- Dogged Nice Guy: Towards Meg, and he somehow gets even less action from her this time around.
- Extraverted Nerd: Basically the extent of his character. Gary is a friendly guy, and completely willing to admit that he's nerdy.
- Gag Nose: It takes up around half his face and covers the top half of his mouth.
- Geek Physiques: Of the "shrimpy nerdling" variety.
- My Greatest Second Chance: Gary makes it one place further than he did the season before.
- Plucky Comic Relief: Just like in School, but this time he has to compete with some of the newbies.
Devin - The Jive Turkey
Similar to Gary, Devin is a shrimpy, nerdy white guy, but unlike Gary, his lifelong dream is to be a "gangsta" - this includes sagging his pants, talking in a near-unintelligible jargon, and rapping awfully. Although originally the second boot of School, he returned at the merge and made it to 7th.
- Expy: Of Total Drama World Tour-era Ezekiel, albeit with much less intelligible speech patterns.
- He Knows Too Much: This is why he's eliminated: he's in the confessional at the same time Trey confesses his true intentions, and Trey catches wind of this and rigs the votes to ensure Devin leaves.
- Jive Turkey: Word-for-word in his label.
- My Greatest Second Chance: Although he placed higher in School, he really only competed in four episodes due to returning - this time around, he makes the merge naturally.
- Piss-Take Rap: Busts out one of these for the music challenge.
- Pretty Fly for a White Guy: Full stop, but sadly, the other contestants don't feel the same.
- Stock Underwear: Of the "boxers with polka-dots" variety.
Helga - The Reader
A relatively minor contestant in School who had little personality other than loving to read books and was voted out right before the merge, Helga's return may seem questionable at first... however, as a result of her early elimination, she has become incredibly bitter and acid-tongued.
- Abnormal Ammo: Has a tendency to throw books at people she doesn't like.
- Blonde, Brunette, Redhead: Forms this trio with the other two girls at the merge: her, Chrissy, and Julia respectively.
- Bookworm: Helga is seen reading a different book every chapter, usually with a Bland-Name Product title.
- Cassandra Truth: Is the first contestant to notice that there's something "shady" about Trey, but everyone else shrugs it off.
- Deadpan Snarker: Between seasons, blossoms into the foremost example of the canon.
- Dumb Blonde: Subverted. Helga's possibly the smartest contestant there, and is one of the only blondes.
- Good Is Not Nice: Helga isn't friendly in the slightest, but she's not really a villain and finds herself aligned with the "good" characters.
- The Load: Contributes very little to challenges and often sits out, choosing to read and snark instead.
- My Greatest Second Chance: Goes from an irrelevant pre-merge boot to the 6th placer and one of the season's biggest Breakout Characters.
- Non-Action Snarker: See The Load.
- Took a Level in Jerkass: After School, Helga transforms from a shy, book-loving sweetheart to a caustic, grumpy load.
Arthur - The Loudmouth
Arthur is an overweight, loud, crass individual who seems to love nothing more than annoying others and spouting out non sequiturs. Unbeknownst to him, his classmate Julia (who harbors a deep hatred for him) is also competing.
- Ambiguously Brown: He's confirmed biracial, but only thanks to Word of God.
- Annoying Laugh: "Haw, haw, haw."
- Catchphrase: He has two, seen above, both of which are run into the ground.
- Companion Cube: Arthur has a "friend" named Vance, who's a single piece of toilet paper covered in a suspicious yellow liquid and topped with a raisin and a single long, stringy hair. Apparently, he can talk.
- Establishing Character Moment: Arthur's first line in the story is "I'm morbidly obeeeese!".
- Fat Comic Relief: "Morbidly obeeeese," as he puts it, and certainly a comic relief character.
- The Gadfly: Is this to Julia once he realizes how much she despises him, and later Trey as well.
- Geek Physiques: Opposite to Gary, he's of the obese, slovenly kind.
- Huge Guy, Tiny Girl: With Julia. He's not significantly taller than her, but much wider.
- Large Ham: Arthur always likes to ham it up, especially when he should be participating in challenges.
- The Load: At best, he's this to his team during challenges.
- The Millstone: This is Arthur at his worst. Especially showcased in the treasure hunt challenge, where the entire chapter is just him annoying his teammates to oblivion but somehow not getting voted off for it.
- Spotlight-Stealing Squad: Arthur and his... odd mannerisms are the main focus of many of the jokes and scenes in the season.
- Teeth-Clenched Teamwork: With Julia, when they're (unsurprisingly) paired up for the wedding challenge and end up winning.
Chrissy - The Tough Girl
Chrissy is an aggressive, tattooed girl who lives in the big city and is a fan of loud music and motorcycles. Despite her intimidating appearance and gruff exterior, deep down she has a heart of gold.
- Action Girl: Great at the challenges and definitely athletic.
- Amazonian Beauty: Despite (or perhaps because of) her intimidating, muscular frame, the guys view her as the hottest girl in the season.
- Blonde, Brunette, Redhead: Forms this trio with the other two girls at the merge: Helga, her, and Julia respectively.
- Deadpan Snarker: Second only to Helga.
- Gender-Blender Name: Halfway through the story, her real name is revealed to be Christian.
- Jerk with a Heart of Gold: Her toughness is mostly just an exterior, as she's a genuinely nice person.
- One Steve Limit: Introduces herself as "Chris" to the other contestants, but the host - Chris McLean - stops her right there and begins referring to her as Chrissy.
- Peek-a-Bangs: To signify her tough yet attractive personality.
- Tomboy: Into lots of stereotypically "masculine" things.
Elena - The Flirt
Elena is introduced as a gorgeous, kind girl who adores boys, even going as far as to flirt with the host himself. Although initially getting along with her team and becoming a leader, it's gradually revealed that she's not nearly as cutesy and friendly as she seems.
- Alpha Bitch: What she ends up as.
- Birds of a Feather: With Trey - both are attractive, cool individuals who disguise their true evil personalities, which is why they end up hooking up at Playa Des Tikis.
- Bitch in Sheep's Clothing: Though not to the extent of Trey, since her bitchy side is subtly there from the beginning.
- Real Life Writes the Plot: Elena was based on a girl the author had a crush on at the time he started the story (8th grade). As this was middle school, the romance was short-lived, and when Elena's inspiration Took a Level in Jerkass, so did the character, explaining her abrupt elimination.
- Shocking Elimination: Justified, as she was originally planned to win.
- The Tease: Is initially presented as this, but ends up as more of The Vamp.
- Took a Level in Jerkass: Come her boot episode, she's explicitly rude and bossy to her teammates and openly antagonizes Nic.
Julia - The Short Girl
Julia is a tiny redhead who's constantly angry, and can be set off by the slightest thing. Having to deal with atrocious teammates as well as her arch-nemesis from grade school, Arthur, just makes her time in Tiki Jungle even more eventful.
- Arch-Enemy: Does he even need to be named?
- Berserk Button: The one thing that makes Julia go from pissed to REALLY pissed is Arthur.
- Blonde, Brunette, Redhead: Forms this trio with the other two girls at the merge: Helga, Chrissy, and her respectively.
- Cluster F-Bomb: After her team continues to lose, she pulls these out of her arsenal."What the @#$%! is wrong with this @#$%! team?!?" shrieks Julia. "You @#$%!s are going to have to learn a little thing called EFFORT, is that @#$%! clear?"
- Earn Your Happy Ending: Is placed on one of the worst teams in Total Drama history, gets into daily fights with her obnoxious teammates, and is forced to compete with her arch-enemy for the second half of the game - but wins.
- Fiery Redhead: Her orange hair only enhances her already fiery personality.
- Groin Attack: Likes to give these to Arthur.
- Hair-Trigger Temper: Basically her main shtick.
- Heterosexual Life-Partners: With Chrissy after the merge.
- Huge Guy, Tiny Girl: With Arthur. He's not significantly taller than her, but much wider.
- Lady Swears-a-Lot: Julia has quite the mouth, but it's always censored.
- The Napoleon: A very rare female example.
- Rant-Inducing Slight: Every so often, Arthur (or another contestant like Devin)'s antics, no matter how small, will send Julia into a fury.
- Teeth-Clenched Teamwork: With Arthur, when they're (unsurprisingly) paired up for the wedding challenge and end up winning.
- Tiny Tyrannical Girl: Becomes her team's new de facto leader thanks to this.
Manty - The Mascot
Manty is a rude, thuggish guy who became incredibly popular at his high school due to the fact that he owns a cool pair of neon green sneakers, but he's not nearly as skilled at socializing (especially with women) as he likes to think he is.
- Casanova Wannabe: He's even worse at attracting women than NIC.
- Companion Cube: Manty cares a great deal about his shoes, and seems to worship them. Things don't go well when they get splashed with mud.
- Jerk Jock: Plays lacrosse, and is definitely not a friendly guy.
- Hate Sink: Manty was explicitly created to be a first boot, and was the result of the author's jealousy towards the "popular" people at his middle school.
- Small Name, Big Ego: Manty is incredibly narcissistic and was shocked to be booted, since he considered himself the best asset to his team and a "hot stud."
- We Hardly Knew Ye: He was the first boot, and he really only popped up to get shat on multiple times.
Nic - The Wannabe Villain
Nic is a huge Total Drama fan who harbors a deep love for former contestant Alejandro. Despite his unattractive appearance, wimpy personality, and out-of-shape body, he truly believes his villainy skills are up to par with Mr. Burromuerto himself.
- Ambiguously Bi: Although he flirts with a majority of the female contestants, sometimes his love for Alejandro comes off as a little more than just idolizing.
- Arch-Enemy: Trey is his, though it's not mutual - Trey barely even knows (or cares) that he exists.
- Big Bad Wannabe: Nic firmly believes he's the villain of the game, but in reality he's just this.
- Butt-Monkey: Nic is frequently injured by animals and challenges, and never gets respect from any of the others.
- Casanova Wannabe: Flirts with almost every girl in the cast, it never works.
- Consulting Mister Puppet: Does this with... his stomach, who he has nicknamed "Abby" and talks to like any other contestant.
- Establishing Character Moment: Nic arrives wearing sunglasses and attempting to look cool, and instantly yells at someone from inside the boat to begin playing Alejandro's Leitmotif.
- Gratuitous Spanish: Whenever he attempts to speak Spanish, it's this.
- Harmless Villain: Nic's "villainy" is used more for comic relief than anything else.
- Leitmotif: Although this is a fanfic, Alejandro's leitmotif is said to be occasionally used for him.
- Not-So-Harmless Villain: There's one moment where he takes a level in badass - masterminding Elena's boot. And then, after plotting in the confessional, he falls in the toilet on accident.
Octavia - The Eccentric Actress
Octavia is a quirky, pink-haired theatre fan who seems to live her life like she's in a Shakespearean romance, with dramatic reactions to basically everything and a very romantic-minded brain.
- Drama Queen: Literally - she's the head of her school's drama club.
- Cloud Cuckoolander: Although not too touched upon, Octavia is definitely quirky.
- Love at First Sight: The second Trey arrives to the competition, Octavia falls in love.
- Out of Focus: Octavia is the only one of the newbies (other than Hate Sink first boot Manty) to not get some sort of major focus or plot, outside of her short-lived romance with Trey, and ends up booted at the end of the pre-merge.
- Ship Tease: With Trey, briefly, but obviously certain events prevent this from happening.
- Shocking Elimination: Lampshaded in-story, where it didn't seem like she was in any danger before getting booted, but the "mystery voter" chose her as his first target.
- Thinks Like a Romance Novel: Octavia's attraction to Trey is dealt with in this way, which is what ends up turning Trey off.
- Woman Scorned: After she finds out that Trey was the mastermind behind her elimination, Octavia's wrath is unleashed.
Trey - The Cool Dude
Trey is a chill guy from Hawaii who's a fan of surfing, nature, and girls, and always has a calm and collected attitude... but not really. This persona is actually a facade that Trey is using to hide his true nature - cocky, evil, manipulative, and from Maine.
- Ambiguously Brown: Though it might just be fake tan, considering he's actually from Maine.
- Beauty Is Bad: Uses his status as Mr. Fanservice to lure women to his side, and then eliminate them.
- Big Bad: Eventually becomes the main one of the story, and after his return in Total Drama Superstar Showdown, the series.
- Birds of a Feather: With Elena - both are attractive, cool individuals who disguise their true evil personalities, which is why they end up hooking up at Playa Des Tikis.
- Bitch in Sheep's Clothing: Trey's strategy. He keeps his plotting entirely secret until he's accidentally exposed in the confessional by Devin.
- Bread, Eggs, Breaded Eggs: From his biography:He loves girls, nature, and girls who spend a lot of time in nature.
- Card-Carrying Villain: In his elimination episode, he turns into this, outright gloating in front of the others and naming his pet llama for the challenge "Evil."
- The Chessmaster: Is able to manipulate other contestants on his team to vote out his "allies," likable threats Meg and Octavia.
- Embarrassing Last Name: "St. Clair" - at least to Arthur, who starts calling Trey "Something-you-put-food-on-at-a-crappy-restaurant Santa Claus Girl's Name."
- Humiliation Conga: After he's exposed by Devin, he spends his final challenge getting beaten up by a llama, getting his "Bonjour Doggy" underwear exposed to the world, being flung into a mud puddle, sobbing, and then being unanimously voted off.
- Laser-Guided Karma: In a last-ditch attempt to get what he "deserves," he steals Julia's prize money from her, hijacks the Boat of Losers, and attempts to make a run for it - but the police come at a very convenient time, give the money back to Julia, and send Trey flying back onto Tiki Island as the rest of the cast speeds away. He ends up spending a year alone on Tiki Island, as revealed in Superstar Showdown.
- Nice Guy: What he initially appears to be.
- Sinister Shades: His sunglasses become these as opposed to Cool Shades when his personality is revealed.
