Owen losing it after Izzy gets hit and taking out Katie, Sadie, Bridgette, and Geoff in eight seconds flat.
Executing Duncan's "Rush The New Guy" Strategy where they consecutively take out the opposing team one by one.
But what really "brings the dinner to the table and eats it" is: Harold's epic dodging skills where he even dodges the final one Matrix Style, and finally catches the ball, giving his team a win. He earns the respect from his personal tormentor Duncan. Even Noah, who paid zero attention to the game, was impressed.
Harold saves his team again to everyone's surprise, with his epic beatboxing, leading the Killer Bass to their second straight come-from-behind win in "Not Quite Famous".
Interestingly, after his performance in Dodgebrawl Harold thought he would get fans who wanted autographs for his epic dodging, but ultimately it's his beatboxing which gets him into the limelight.
"Paintball Deer Hunter":
Beth gets herself one of these in the episode when she gets fed up with Heather's unreasonable demands after Heather ordered her to steal a bag of chips from the mess hall without getting spotted by Scary Black Man Chef Hatchet instead of focusing on the actual challenge. Beth succeeds in evading Chef Hatchet, but begins to wonder why she put her life on the line for someone she never liked. Realizing Heather had been taking advantage of her, Beth eats the chips by herself, opens paintball fire on Heather with extreme prejudice and then breaks off the alliance.
Owen (hunter) spent half the challenge chasing DJ (deer) down with a paint ball gun. When he finally ran out of ammo DJ responded by tossing his ass off a cliff.
Lindsay, after spending the entire season under Heather's heel, finally knocks her off her high horse in "That's Off the Chain", with an impressive on-the-fly, curse-riddled tirade.
Lindsay: You really are mean! And all that bad stuff people say about you is true, like how you're a two-faced, backstabbing, lying little -
(censor bleep with a censored finger, shocked reactions from Chef, Owen, DJ, and Heather, and a smile from Gwen)
Lindsay: I always told them they were wrong. I stood up for you because I thought we were BFFs! but they're right! You really are a two-faced, backstabbing, lying little -
(censor bleep with a shocked Duncan, a shocked loon, and a smiling Chris)
And guess what? I don't want to be BFFs anymore. I'd rather spend the day staring at Owen's butt than shopping with you! and P.S. Your shoes are tacky!
Gwen: Yeah! You tell her!
Later, in the confessional cam:
Lindsay: I don't know what came over me. Oh wait, yes I do! Heather's a total - (censor bleep)
Izzy's epic fist fight with Chef (who is twice her height and three times her muscle mass) in "Hide and Be Sneaky". Not only does she parry everyone of his blows, she even slo-mo leaps into the air and kicks him in the face, before diving out of the window (shattering it) and screaming her Catch Phrase: "You'll never have me alive!", and Izzy and Chef continue their slo-mo pursue of each other before finally reaching the dock. Pity she didn't make it.
"Hook, Line, and Screamer":
Gwen kicking a serial killer in the jaw, repeatedly, bad enough that the serial killer says that he was treated better in prison. Hardcore.
Duncan proving himself Genre Savvy by letting each of the other campers leave the group one by one so he can be the Final Guy, before successfully taking on Chef Hatchet in a friggin' chainsaw fight on the docks.
Leshawna attempting to confront the "killer". She still ran away, but even then, it was pretty brave of her to try and stand up to him. The fact that she laughed it off afterward just adds to it.
The entirety of "I Triple Dog Dare You!", especially when Lindsey's dare is the same threat Heather had made towards her; which results in Heather getting eliminated and losing her hair. In just one episode, Heather is forced to pay for all the cruelty she inflicted on the others.
The end of the season; After twenty-six episodes of abuse, humiliation, and injuries, Duncan, Owen and Geoff take Chris and toss him into the lake, just to show what they think of him. Chef Hatchet approves.
Chef: I've been wanting to do that all summer! How do ya like that, pretty boy!? Huh?!
Geoff: Oh, Chef...
Owen: (snickers) You're next, dude!
Total Drama Action
Harold calmly knocking Duncan out after he insults Leshawna in "Crouching Courtney Hidden Owen".
Harold using his mad skills to save the entire cast from drowning when Chris' stunt goes horribly wrong in "Masters of Disasters".
Despite Courtney's derailment this season, her managing to do a series of backflips through deadly lasers when everyone else was either stuck or couldn't do it, followed by her doing a high flying kung fu kick to the glass the shuts off the lasers was very badass indeed. Everyone, including Duncan agreed.
Badass Action Girl Courtney takes on a shark (because she was pissed at it) and wins, although she did get wounded in the process. Later she has a rematch with the shark (as well as a few of its buddies it called in), while it isn't showed on screen, it's implied that she slaughtered all three of them.
When Harold is about to leave the game Duncan insults him one last time, only for Harold to pantse him at the last second.
Even more vindicating, Duncan admits he had it coming.
Beth giving up an opportunity to win to save Duncan from being crushed.
"Celebrity Manhunt's Total Drama Reunion Special" is like one big Crowning Moment Of Awesome that goes on for the entire episode. All twenty-two contestants, people who have spent every single season fighting, backstabbing and insulting each other, join forces in order to bring down the reality show cast that Chris plans to replace them with just so that they can keep being famous instead of going back to their normal lives. As Chris put it:
"Their dream is to claw their way back to fame no matter what it takes! Cheating! Shameless self promotion! Sabotage! I LOVE THOSE KIDS!"
Duncan telling Chris off in the first episode and quitting rather than degrading himself by doing a season of musical numbers. He's dragged back into the game several episodes later, but still.
Tyler saving his teammates' lives by hanging on to the edge of a cliff using his insanely strong fingers. And after everyone climbs up to safety, he pulls the sled back up with a single tug, eliciting a cheer from his team.
Geoff and Bridgette repairing their relationship in the first aftermath of the season is in my opinion a moment of heartwarming, funny, and awesome all in one. In the sense of awesome the two managed to piss Blaineley off enough for her to go berserk on stage.
"I See London...":
Noah taking over leadership of his team after Alejandro goes missing in "I See London", even dropping his usual sarcasm and laziness in favor of actually working. Then in the final moments of the episode he brushes off his elimination boredom, puts on his parachute, calmly warns his teammates about Alejandro, and then becomes the first World Tour contestant to ever take the Drop Of Shame properly.
Owen and Noah doubling back to the torture chamber to pick up Tyler, despite knowing that time was of the essence and losing teammates didn't cause score-deductions. Compare and contrast the members of Team Amazon, who barely notice their dwindling headcount.
Cody is told to throw the challenge so that his team can vote off Gwen. Instead of obeying, Cody proceeds to fly into the air and win against Tyler. It gets even better when you realize he defied Courtney, who treated him like shit the entire episode.
Courtney kicking Duncan in the kiwis.
Tyler relentlessly trying to break down Owen's cell wall to save him, even after everyone tells him to give up.
"NEVER! LEAVE! A! MAN! BEHIND!"
Duncan successfully blackmailing arch manipulator Alejandro into guaranteeing Duncan won't be voted off.
The episode in general occurred in Area 51 where a chock a block of alien movies are referenced, especially the facehoggers from Franchise/Alien.
Owen using himself as the last cannonball to sink Team Amazon's ship, thus securing victory for his team. There's even a freeze frame of each member of Team Amazon going Oh Crap a second before he makes contact.
Chris yelling at Sierra and eliminating her on the spot in "Awww, Drumheller" after she blew up millions of dollars worth of equipment just by being Too Dumb to Live.
Alternatively, Sierra blowing up the plane and causing Chris' meltdown in the first place, there's no denying that he had that coming for quite a while.
Alejandro singing the show's first ever Villain Song, This Is How We Will End It. And what a song it is.
There's the time Harold out-surfs Courtney. It backfires, but it's still cool given how she always tries to sell herself as The Ace.
"Planes, Trains, Hot Air Mobiles":
Although Heather and Alejandro's methods to get to Mexico are pretty neat, Cody's has to take the cake here. While Heather caught a train and Alejandro stowed away in the shipping truck, Cody and Sierra put together a hot air balloon from the random debris in the airplane wreckage. Now while this is pretty cool all by itself, the awesome happens later on. After their balloon gets destroyed by power lines, Cody feels he can no longer continue, and gives up. Not willing to let him quit now that he's come this far, Sierra finds what they need, gives him the pep talk that he needs, and they catch up with the others using one of the craziest methods ever seen in this show: Rocket-Powered Wheelchair
I'm Gonna Make It. The first half features Sierra and Cody singing a duet as she manoeuvres their balloon around obstacles while Alejando and Heather do a literalMasochism Tangoatop a moving train. The second half is done in a sort of Travel Montage mode that displays the final three's movements across a map, complete with Heather waving mockingly whenever she passes an opponent.
Geeky Weakling Cody who got pushed around by the cast for two seasons, and had to be carried to the end of the season by his favorite stalker Sierra, finally stands up for himself and engages Bigbad in a swordfish fight.
Heather managing to trick both Cody and Alejandro during the tie-breaker, while tied to a pole. It's even cooler when you remember that earlier in the episode Owen had commented that she wouldn't be able to do any harm while tied up.
Versus, which features gigantic, god-like versions of Heather and Alejandro rising out of volcanoes and throwing lightning bolts at each other.
Cody's repetition of "Al" just to press Alejandro's hidden Berserk Button.
Although it was harsh, Heather tricking Alejandro into giving up the prize was pretty awesome, providing a sweet sense of poetic justice in regards to the girls he'd tricked (especially Bridgette) and reminding us just why Heather is the most formidable competitor.
Everyone (with the exception of Courtney) cheering for Heather when she finally defeated Alejandro, even sworn enemies like Gwen and Leshawna.
All the contestants laughing in delight as Chris' boat sinks.
Sierra as a whole is pretty awesome. She's multi-talented and Genre Savvy and knew right away when Heather was trying to trick her.
Total Drama: Revenge of the Island
Jo reaching the island...only to realize Dawn was first..completely dry :
Jo: Woohoo! That's what I'm talking about! First one on the isla...(gasp to see Dawn first) How did you...You're not even wet!!!
Bubble Boy, midget Cameron experiences an adrenaline rush and bursts through the webbing (that Lightning, Jo and Brick couldn't break free of) and outright slaughters a mutant spider that was several times his size in "Finders Creepers"!!! Turns out the spider was Izzy in disguise, but considering she's capable of regularly beating up a Scary Black Man, that just makes it even more awesome.
In the same episode, Chris gets stuck in the septic tank, and the interns use this as an opportunity to get back at him for all the hell he put all his interns through for 4 seasons
In "Grand Chef Auto": Mike's epic Battle in the Center of the Mind where finally getting pounded by all five of his personalities, he hears Zoey calling him and declares he has had enough. He goes and Offhand Backhands Vito, beats up all of his personalities without breaking a swear, before finally declaring "This brain is under new management!"
Also, Duncan cameos against his will and promptly breaks free. In the end, he blows up Chris' latest monument to himself, Mount Chrismore. Even Chef is impressed.
From a meta, out-of-universe standpoint, the fact that Cameron came the closest that any Total Drama contestant ever has to being the sole finalist of the entire world. Considering how many countries air Total Drama, it's a huge feat for Cameron to only lose in one country (the U.S., but only on the broadcast version, fourtunately, iTunes and Netflix both have Cameron's ending of the season.
Total Drama All-Stars
The shot of all the Vultures laughing deviously, all surrounded by flames (except Gwen).
Lightning punching Fang down into the water as he jumps off a cliff.
Alejandro escaping the drama machine when it blows up from the water.
Sierra beating up the sharks in an underwater fight. In the same challenge, Zoey rescues Mike with Improbable Aiming Skills.
Mike is shown in "Evil Dread" to have a better handle on his personalities when Manitoba comes out. He is able to focus his skills on the challenge, keep Manitoba's sexism under control, and compliment Zoey all the while.
Manitoba. When he comes out in this episode, the first thing he does is spin his arms rapidly, dig through the beach, and find a puzzle piece in a few seconds. He spends the rest of the episode using his tracking skills to find more pieces, and stops Scott from cheating.
Mike's new evil personality, who is implied to have taken over the other personalities, wants to overtake the game, and has an awesome emo hairstyle.
Zoey going full Action Girl in "Saving Private Leechball", being the one who defeats the most villains, specially Jo in a one-on-one duel, even doing Bullet Time to dodge Jo's leeches and catch one in mid-air to use as ammo herself.
While not as awesome as he only hit the more threatening target by accident and got hit himself directly after, Cameron calculating the degree and objects needed to ricochet into hitting Gwen (spared by Duncan instead) in mere moments qualifies.
Lightning getting his revenge on Jo by taunting her with a pre-recorded message before he was eliminated.
Courtney spends some time pretending Duncan doesn't exist, when Duncan forces her to admit it. Instead of whining or giving him a big Reason You Suck Speech , she just screams "So what?" and it's enough to scare Duncan.
Alejandro swallowing his vomit in "Food Fright".
Sam "powering up" at the end of "Food Fright" and beating Alejandro to win the challenge for his team, even though he botched it up in the end.
Even if losing some points due to being a Smug Snake using a Wounded Gazelle Gambit , Alejandro doing the challenges by using his hands for movement to continue pretending he can't use his legs is pretty awesome too.
Cameron surviving a night in Boney Island by using his brains and a lot of courage; seriously, getting THAT close to a bear, on purpose, so the animal can do THAT on him?
Gwen dumping Duncan in "Moon Madness". It ends up making Duncan confused.
Gwen saving Courtney from a vicious deer in "Moon Madness".
Heather exploiting the dynamics of her teammates (Scott and Courtney getting close, Gwen and Cameron bonding) to create an anti-Alejandro alliance while having the later convinced that she wouldn't try anything against him too soon was awesome. Of course, Alejandro one-ups her when he manages to steal her immunity idol, making him the only judge of who's going home this night... and he chooses Heather. The look on Heather's face as she realizes what's happening is priceless.
Alejandro KO-ing his brother Jose in "Suckers Punched". Combined with a Crowning Moment of Heartwarming when Alejandro delivers the final blow. "And THIS is for calling ANY aspect of Heather unattractive!"
Mal had some nice ones too. The topper being throwing Izzy out of the ring. IZZY.
Mal's first scene, where he makes a bunch of animals stampede across an unsuspecting Chef, then steps on the latter's fingers.
Izzy is able to see through Mal's disguise just by looking at him. She could even hear what Mike said from inside Mal's head.
Duncan catching and defusing Chef's explosive, and using it to blow up Chris' mansion... uh... cottage.
Zoey risking her life by balancing on a stick in piranha-infested water for the sake of getting Mike to take control of his body again. And for a few seconds, it actually works.
Cameron of all people coming up with the idea of holding Scott on a stick so Fang can pull their raft. Let me tone it down for you cowardly, 3-foot, resident-nerd Cameron.
Once freed, Scott immediately shoves Cameron into the water for doing that to him. It was immensely gratifying.
Mike somehow freeing himself from the boulder he was shackled to.
Chef running after Chris with his meatball gun to save Chris, and Gwen winning the challenge by blasting Ezekiel with meatballs, saving Chris of all people and then rushing to save Cameron. And to top it all off she sends Alejandro to Boney Island.
Mal gets Alejandro (who is considered the most manipulative contestant in Total Drama history!) voted off in "The Obsta-kill Kourse" after manhandling and humiliating him pretty much through the whole challenge He even dominates him physically with just one hand, and it's revealed he can access Mike's other personalities' abilities even if they resist, explaining his Super Strength and other abilities; also, Mike manages to 'release' Svetlana from Mal's control, cutting his access to Svetlana's athleticism.
But for what it's worth, even though Alejandro was eliminated he didn't go down without a fight. His most notable moment was when he forcibly flung off all the leeches he had been shot with.
Also, when Mike sets Svetlana free, Mal gets thrown into a pit of angry snapping turtles. For all that he's done, it's nice to see Mal get some punishment.
Chris punishing Courtney for trying to poison his interns with her disgusting sundae. Also crosses with heartwarming.
Chris: Everyone has to eat their own sundae. 'Member? You won't get anything else to eat until you finish the sundae you thought was good enough to feed my interns. I wouldn't feed them that.
It's worth noting that this is pretty much the only time in the series where Chris outright scolds a contestant for their behavior in a challenge. Throughout the series he's allowed rule bending, deceit, trickery, and has personally inflicted all kinds of crap on the contestants (in World Tour he had people literally strung up in medieval torture racks as part of the challenge). Even in situations like Heather reading Gwen's diary during the Talent Show challenge in Island, where Chris thought it was uncool, he still allowed it. The fact that a contestant deliberately harming his interns is where he draws the line is pretty awesome and heartwarming.
In the same episode, Zoey manages to survive a crocodile attack despite being stuck in the swamp and using only one hand because she's holding the ice cream bowl with the other. Also, we get to see a brief bear vs crocodile fight.
Mike setting Vito free by slamming the Demonic Dummy of Mal into Vito's chains. Said dummy was just beforehand laughing evilly at them. Vito then, for the first time, obeys Mike without hesitation.
Zoey figuring out Alejandro's clue and learning about Mal via the disk.
It doubles as Nightmare Fuel, but Mal manages to even creep Chris out, and sabotage Scott and Gwen's treasure hunts!
Zoey getting the Yeti back to Chris.
Svetlana's speech when Mike was about to assume Mal's the original personality.
Mike telling Mal, that Mal's a part of him that he doesn't need anymore as Mal fades away.
Mike regaining his body and punching Fang so hard that he flew offscreen and lost a tooth! Shortly afterwards, he gives Al the tooth (after he reveals that he now has all the abilities of his personalities now), causing Fang to chase after him.
Gwen hitting Heather on the head with a pole.
Mike winning the million big ones.
Total Drama: Pahkitew Island
During the drop from the Airplane Ella and Sky managed to save themselves with their respective skills while Jasmine saved two others mid-fall.
Samey finally retaliating against her twin sister by feeding her a fruit that made her unable to talk and pretend she was Amy so that Amy (who Chris thought was Samey) would be sent home.
Samey: (pretending to be Amy as Amy's unable to talk) Oh ignore her, she's just trying to get sympathy. Aren't you, Samey?
(Amy realizes that Samey tricked her and tries to talk but it's muffled)
Chris: Can't understand what you're saying Samey, but it really doesn't matter, because you've been voted off.
Ella may have gotten a raw deal, but she left the island on her own terms after saving a teammate.
Said "Own Terms" include a full blown musical number (outwitting both Chris and Chef in the process) and not showing a shred of resentment for her elimination, before being carried into the cannon by birds. That is how you go out in style.
Jasmine using Topher as a human battering ram to escape the gopher hole they were trapped in.
