Hailfire Peaks: In "Scarlett Fever", Pahkitew island becomes this after Scarlett messes with the island's controls, and after her elimination half the island is left on fire while the other half is covered in ice.
Hair of Gold, Heart of Gold: Almost every blonde haired contestant is nice and kindhearted, with the most prominent examples being Bridgette, Lindsay, Owen, Geoff, and Dawn.
Played with in "Jamaica Me Sweat"; Tyler gets a momentary shock from an electric eel but is unhurt. Gwen, however, gets shocked by three electric eels and has to be rescued by Alejandro and taken to the infirmary.
Played straight in "The Ex-Files", where the guys get shocked by a laser, an electric fence, a clone pod, and an alien, in that order, and don't take any lasting damage.
Hartman Hips: Beth, Blaineley and especially Anne Maria (her hips are massive).
The Hat Makes the Man: In Revenge of the Island, Mike (who has multiple personality disorder) becomes an adventurer called Manitoba Smith whenever he puts on a hat.
Hollywood Healing: Played around with. The show relies on Amusing Injuries a lot (see: Tyler), but it also shows some injuries taking a realistic amount of time to heal, most notably Heather's black eye that took about 2 or 3 episodes to disappear.
In "The Sucky Outdoors", Duncan uses one to scare the daylights out of the Killer Bass at the end of his campfire story.
Duncan: ...because there, hanging from the door handle, was the bloody hook. They say that this killer is still alive, wandering these very woods. He could be just about anywhere, really. Maybe even right HERE! (whips out hook)
Killer Bass: AAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHH!
The Escaped Psycho Killer with a Chainsaw and a Hook from "Hook, Line and, Screamer".
Hopeless Suitor: Cody, whose advances towards Gwen are either ignored or outright rejected.
Horrible Camping Trip: "The Sucky Outdoors" features an overnight camping trip as the challenge; the Screaming Gophers get attacked by a bear and have to spend the night stuck up a tree, while the Killer Bass are unable to find food and get their tent burnt down. Then, just as Courtney angrily declares that the situation can't get any worse, it starts to rain.
Blaineley received a pretty nasty one in season three, being thrown from the plane without a parachute, trapping her in a full body cast, only for her to suffer even more when she has to represent "Team Heather" on the final Aftermath.
Alejandro gets kicked in the balls by Heather, thrown off the volcano, trampled by the rest of the cast, is burned in the lava flow and is revived in the same manner as Darth Vader.
While Scott definitely had karma coming, he didn't deserve ending up in a machine in a near coma-like state. Thankfully, he gets better.
When reading The History of Canada, Chris says that the North American beaver makes "a dam fine hat."
Chris (again) in the pilot of Action
Chris: Really liking the twos today. Must be Tuesday."
(complete silence from the cast)
Chris: Yeah I don't get paid to write this show.
Indecisive Parody: The first season started out as an animated parody of reality shows. The focus on shipping and other such plot tumors have essentially made it a totally pre-scripted (read: slightly more scripted than usual) reality show that happens to be animated.
Informed Ability: Oh boy. One wonders if the writers even read the character biographies at any point.
Many are just shortened forms of their actual names: Geoff calls Bridgette "Bridge", Owen calls Izzy "Iz", Tyler calls Lindsay "Linds", and both Owen and Cody call Alejandro "Al" (which happens to be his Berserk Button).
Bridgette uses a lot of pet names for Geoff, including "Schmoopy-Boo", "Cutie-Patootie", and "Sweetie".
Sugar throughout Pahkitew Island, especially to Ella.
Jerkass Ball: Almost every single character gets it at some point of the series. Even DJ gets it halfway through the first season when he picks on Harold, along with Geoff (who is also carrying it) and Duncan.
Jerk Jock: Lightning, who becomes season four's lead antagonist after Scott is eliminated.
Chris McLean rates highest in this regard, though he eventually gets what's coming to him in "Brain vs. Brawn: The Ultimate Showdown" when he is arrested by the RCMP for illegally turning Camp Wawanakwa into a toxic waste dump and gets throughly decontaminated. However come All-Stars, he's been granted parole.
Sugar rates pretty high as well. Aside from her elimination in the last episode before the finale, she gets no real punishment for any of her actions throughout Pahkitew Island which is shocking considering how she was the arguable main villain and all of them prior to her at least got some form of comeuppance.
Duncan also counts considering his actions in World Tour. Though he too got his just deserts in All-Stars when Chris has him arrested for blowing up his cottage in an attempt to prove that he was still bad and thought that he would simply be taken to juvie.
Keeping the Enemy Close: Heather uses her understanding of what reality show producers like best to get to the final three of Island, and so despite hating Leshawna, acts nice to her for this reason. Despite this, it doesn't last long at all.
Scarlett in Pahkitew Island. The episode in which her true nature is revealed, takes a very dark turn from the usual lighthearted nature of the series. While the series occasionally puts the contestants' life on the line, her actions make this one of the few occasions where all of them are a few strokes away from imminent death, and just like Mal she is completely unphased with the prospect of them dying.
Justin gets rejected by his crush, pushed of a tower by said crush, getting hit by parts of the tower on the way down. When he is eliminated, no one really cares to see him go.
Courtney gets eliminated by her boyfriend for being so uptight.
Alejandro gets trampled by the other campers, burnt by lava, and forcefully shoved into a robot suit to "heal." And in his ending, this happens after he learned he won the million, alternately this also happens in Heather's ending after she won the million.
Blaineley falls out of the plane with no parachute, crashing into a house and being put into a full body cast and dolly.
Scott gets catapulted off the island with Fang, who mauls him to the point where he gets the Captain Pike treatment.
Mal is erased from Mike's mind, which is pretty much the equivalent of being Killed Off for Real.
Chris himself gets it at the end of Revenge of the Island by being arrested.
Laser Hallway: Used in "Dial M for Merger" and "Can't Help Falling In Louvre".
Advertisements inevitably indicate who the remaining contestants are by showing scenes from upcoming episodes, and promotional material during or after a season finale tends to be rather direct about naming the finalists. The worst example is an ad for the third season that revealed the two finalists of the second...when the second season was still in progress with six contestants remaining.
Some TV Guide-esque website posted small paragraphs about each episode. Oh, don't worry, the paragraphs don't reveal anything about the episode they're talking about: just who was eliminated in the last one. For example, the summary for "I See London..." says 'With DJ gone, only 2 teams remain!', the summary for "Greece's Pieces" says 'Owen is missing his little buddy Noah...' etc.
Latin Lover: Alejandro, he even says that his Latin blood keeps him hot in the snow.
The show has a specific tune that plays during heartwarming moments.
Whenever Justin flips his hair or removes his shirt, an Ethereal Choir is heard.
The Jaws theme can be heard whenever Izzy is sneaking up on someone.
Creepy horror music would start to play whenever Trent talked about his obsession with the number nine; the same music plays whenever Sierra has a stalkerish moment, such as when she reveals how much information she has on Cody (obtained by calling members of his family pretending to be a telemarketer).
Alejandro has a Latin theme tune.
Duncan has a rendition of Bad to the Bone, which was surprisingly played for Tyler a couple times in World Tour.
Brick has a military drum leitmotif.
In The Hall of the Mountain King is Mal's. Given that it's a song for people being sneaky...
Lesser of Two Evils: Aside from the Big Bad, some seasons contain a secondary antagonist who are stil troublesome, but are greatly dwarfed in evil.
Played with by Chef Hatchet. Though he is actually a competent chef, it's his job to make barely edible slop for the contestants.
Played with by DJ's Momma. She has a seasoning blend that can make any disgusting food palatable; however, when she gets her own cooking show, her food proves to be literally lethal because of how cholesterol-laden it is.
Lindsay accidentally poisons Trent with ill-prepared fugu blowfish in "Who Can You Trust?".
In "Eat, Puke and Be Wary", the final four's (sans Cameron's) dishes are lethal in more ways than one.
Male Gaze: The show has a lot of this, but the most noticeable is Courtney. Courtney gets a bunch of butt shots for no other reason besides Fanservice in every season in which she participates. It's especially noticeable when she does her Cheerleader bit. Heather and Zoey (in All-Stars) also.
Maniac Monkeys: Mandrills attack the contestants in "African Lying Safari", and DJ gets attacked by some in "The Am-AH-zon Race".
Meat-O-Vision: Owen starts hallucinating that his teammates (and Chris) are food items after he gets injured (and then locked in a safe) in "Ocean's Eight-Or Nine".
Mean Character, Nice Actor: Thanks to Christian Potenza's series of video interviews of the series' voice cast, we can see that behind the voices of all the Jerkasses and Alpha Bitches populating the show are some of the nicest people in entertainment, particularly Rachel Wilson (Heather), Emilie-Claire Barlow (Courtney), and Drew Nelson (Duncan).
Mercy Kill: The Villainous Vultures were allowed to vote off a member of the Heroic Hamsters in "Suckers Punched". Despite the fact that almost everyone else on the team was more of a threat, the Vultures voted off Sierra so that she could meet up with Cody and get back to her blogs again, hopefully regaining her "sanity" (and Cameron's).
Messy Pig: In "I Triple Dog Dare You!" Heather gets cannon blasted into a pig's mudpile.
Sam demonstrates his Super Reflexes in "Runaway Model" by unbaiting one without setting it off. He ends up setting off half a dozen other traps because he accidentally stepped on the trap he just undone.
Scott finds one in Chris' garbage bag after drawing an undesirable objective in "Up, Up And Away In My Pitiful Balloon".
The third season is a musical. Good luck determining that from any of the marketing past the original trailer and pamphlet.
An ad for the wild west themed episode of Action showed Duncan and Bridgette in a showdown. Not only did this not happen in the episode, but Bridgette had been eliminated by that point and did not make an appearance.
The original trailer for Revenge of the Island featured Staci, with a full head of hair, getting eaten by Larry. However, in the first episode of the season she loses her hair after receiving the Toxic Marshmallow of Toxic Loserdom and the previously mentioned scene never happens.
Alejandro's endless arsenal of talents as part of being The Ace.
Sierra's ancestral teachings go from Chris McLean Scholaring to basket-weaving.
Tyler's incredible finger strength. This one is an odd case, because it appeared out of nowhere, was reused in another challenge in a later episode, and then wasn't even REFERENCED when he tried to punch through a metal door.
The first season had numerous references to interns being injured or killed in various accidents, presumably due to a lack of safety precautions. Particularly noteworthy is the incident when an intern dies whilst testing part of the final challenge. Chris reacts by saying to himself, "That seems safe enough."
Camp Wawanakwa also suffers from "No EPA Compliance" in Revenge of the Island due to the adverse effects of toxic waste to the local fauna and flora after Chris rents it out as a dumping ground to a "nice, family-oriented" bio-hazardous waste disposal company.
Played with with Izzy in Island - she flees when a helicopter comes to arrest her, meaning that no one is eliminated that round, but she later returns to the game.
Two in Action. One quit and one ejection, though neither are normal.
World Tour had Duncan quitting and the informal "elimination" of Ezekiel by Chris, followed by the formal elimination of Sierra after she blows up the plane (in the same episode she was granted invincibility, no less).
Revenge of the Island sees Anne Maria walk off in the seventh episode, after getting a giant diamond from Ezekiel in the mine. Too bad it turned out to be a fake.
All-Stars has Duncan getting arrested, thereby removing him from the competition.
Off Model: Some of the character heights vary a bit for particular scenes, and that's just the tamer part. Heather has been drawn with her original hair◊ early in Action, when she was supposed to be bald, and Katie was once missing an arm.◊
Oh, Crap: Nearly every contestant that winds up in the bottom two for elimination automatically gets this expression.
Only One Name: Everyone except Chris (McLean), Chef (Hatchet), Harold (Norbert Cheever "Doris" McGrady V), Cody (Emmett Jameson-Anderson), DJ (see above), Alejandro (Burromuerto), (Mildred) "Blaineley" (Stacy Andrews-O'Halloran), Dakota (Milton), Brick (MacArthur), Cameron (Coduroy Wilkins), and (Rudolph) "Lightning" (Jackson).
During the first two seasons Gwen and Trent were often bewildered and annoyed by the behavior of their fellow contestants and the lunacy of some of the challenges but they both reached the "acceptance" stage by the time season three arrived.
Noah is this for the most part, especially during World Tour.
Dave starts off as this, spending most of his time complaining about his teammates' strange personalities and bizarre behavior, but once he begins crushing on Sky his mental state steadily deteriorates.
On the Next: Shown at the end of "Not so Happy Campers - Part 1".
Operation Jealousy: Employed for three episodes in a row in season three. Courtney flirted with Tyler (to make Duncan jealous), Alejandro flirted with Courtney (to make Heather jealous) and Heather flirted with Duncan (to make Alejandro jealous).
Sierra: Oui, my friends! Now I'm stuck telling you: If you fall in love with a boy on TV, and then audition to get on his show, and audition again, and finally get on his show, and be nice to him, and do nothing but kiss up, you will still, oui, end up in Paris, oui, feeling despaires, and the boy won't even take you outside!
The Peeping Tom: Cody tries to watch Gwen change into her swimsuit by looking through her cabin's screendoor in "Up the Creek", and "The Am-AH-zon Race" reveals that he owns a pair of X-Ray glasses which he evidently uses to spy on the rest of Team Amazon.
Pepper Sneeze: In "Beach Blanket Bogus", Trent spills pepper on his breakfast and then tosses it over his shoulder, straight into Heather's face, causing her to sneeze for the rest of the scene.
When Sierra accidentally blows up the jet in "Awwwwww, Drumheller", Alejandro shields Heather from the blast. He is also concerned after Sierra recovers from the explosion.
Heather is infamous for faking these for ulterior motives, but she does occasionally play it straight: She consoles a heartbroken Courtney in "Greece's Pieces", and gives Sierra a headdress to cover her bald head in "Planes, Trains, and Hot Air Mobiles".
Chris allows Katie to reunite with Sadie in "Who Can You Trust?". Also, when Harold eliminates himself in "Super Happy Crazy Fun Time Japan", Chris wishes him luck without a hint of sarcasm.
Pink Girl, Blue Boy: The mostly-female Team Amazon has a pink logo while the mostly-male Team Chris Is Really Really Really Really Hot has a blue one.
In World Tour, it turns out that Courtney's and Trent's fears that Duncan and Gwen were becoming more than friends were pretty understandable after all.
In Pahkitew Island, although Shawn's zombie phobia usually has him labeled as a Cloud Cuckoolander, it has proven useful on a fair few occasions. As if his Beserk Button is pushed, he can perform amazing feats.
During the first three seasons eliminated contestants were sent to either the Playa des Losers hotel (season one) or the aftermath studio (seasons two and three) so that Chris could keep tabs on them in case he wanted to bring someone back into the competition.
Most of the first three seasons' cast gets this in Revenge, with some showing up in single episodes.
With the exceptions of Owen, Ezekiel, and Izzy, none of the characters that did not compete in All-Stars appear during said season.
With Duncan blowing up Chris's villa, to desperately prove to everyone (and himself) that he wasn't going soft. Caused him to be arrested, heading to "adult prison" it seems very unlikely he'll ever be coming back, especially since there is no way in hell Chris would allow him back
