This is simply what you think is the (not some of the, the) best example of any trope (an objective trope, not subjective, since this already is subjective). The "Crowning Example" if you will.
There could be several reasons you think an example is the best.
You think it's the best in terms of illustrating the trope.
You think it's the most well done.
It's your favorite play in that trope.
You just really like the source material.
Oh, several things before you list examples:
Each troper gets one example per trope, no more.
Don't go "no, this is," or phrases like that. This is about our own personal favorites.
Freedom Fighters. The main rebel base for the first half of the game is in a part of the sewer with a thirty foot high ceiling, and the tunnels leading to it are big enough for rafts that can hold supplies, ammunition, and twelve people comfortably. ~ raan
Teenage Mutant Ninja Turtles. The sewer was big enough to stage major fight scenes down there, plus the water down there was very clean-perhaps because Nobody Poops-and was as wide and deep as a river. ~ wrybread
Mirror's Edge. They are absolutely massive, filled with more than enough space to do massive trick jumps all over. Admittedly it was justified as being the main sewer system for a massive city, but still. Mack
The MOTHERF**KING' Queen from ICO!!! She emotionally abused and manipulated her own daughter for years Even locking her in a freakin' HANGING CAGE!! (which was actually considered a form of torture in the Middle-Ages.) And her sole motivation for doing so was to Make herself immortal by possesing her daughters body. WHAT ABITCH!!! ~ Lunacorva
Ragyo Kiryuin. It would be very hard for any character to pull off as many forms of abuse as her without her particular story. Experiments on both her children when they're INFANTS, pulls Parental Abandonment when she thinks said experiments killed Ryuko, tries to have the children's father killed once and later successfully manages it, molests Satsuki, pulls a strange near-literal form of Mind Rape on Ryuko, is an Omnicidal Maniac, and repeatedly beats the crap out of Satsuki and Ryuko and people they know. ~ stupidskeleton
Rhaegar Targaryen is unusual in that he's a post-humorous example. He was known to be excellent at everything he tried, and was beloved by the majority of the realm. Unfortunately, he was just slightly worse at fighting than Robert Baratheon, leaving him dead, and the far less politically-adept Robert as king. ~ King of the Mime Swing
Seconded. No other woman has a body count in the tens of thousands. No other woman has a trope page all to their own on how much of an Action Girl they are. No other woman has the Quit Your Whining attitude demonstrated by the likes of Buffy or Kim. 
The book-reading scenes in the movie might have been a clue...but apparently they weren't.
Fullmetal Alchemist. For the majority of the last decade, at least. During that time, the first anime series' popularity was massive (and for good reason), so much so that it was much more well-known in the United States than the also amazing manga it was partially based on. The Brotherhood adaptation has... changed things, however.
Yu-Gi-Oh!. It's a trading card game based off an anime based off of a manga, yet criticisms will be made on how the second doesn't follow the direct rules of the first (that is, the criticisms that don't just insult the series in general). Not the Most Triumphant for the original source being erased from public knowledge completely, but the winner for the manga having been extremely popular...yet those from every walk of culture still think the true "canon" of the series come from the cards. ~ Shadow Stained Sky
Shrek. A short picture book about an ogre that was adapted into a full-blown franchise, with four films, one spin-off film, three shorts, and a stage musical, along with two dozen video games. — Astfgl
Freeza. In the anime, after Goku allows him to power up to 100%, he begins to put up much more of an even fight, and becomes one more example of "good guys allowing the bad guys to power up and gain an advantage" that the series gets lampooned for. In the manga, Goku let's Freeza achieve full power because even then, he stillwasn't nearly a challenge for Super Saiyan Goku. ~ King of the Mime Swing
Seconded; The guy is a Dark Messiah who rarely loses his cool, has his own religion with him as the figurehead, he's a master of ever sort of plan and all the while he maintains a demeanor that could almost be taken for serene. Just don't betray him. No, seriously don't! ~ The Harbo
The Moment, Doctor Who, a superweapon capable of destroying anything from a person to multiple galaxies. It has never been used out of fear since it is known to have developed a conscience, capable of judging anyone using it. When it is finally used in the time war it presents the user with an alternative that solves all their problems without killing.
Boatswain Matthews almost-hugs Lieutenant Hornblower who is his superior. Remembering his rank, he just touches his arms, shakes his hands and laughs. Air Hugs are usually used to express awkwardness or feeling uncomfortable showing affection, but this feels lovely, warm and manly. ~ X Fllo
Leliel in the original, even moreso. That shadow on the ground is it's real body. The monochromatic sphere hovering in the sky? THAT is its shadow. Oh, and somehow, the two appear to be physically connected, i.e. entering one and coming out the other... and the shadow appears to have infinite space within it, i.e. a pocket dimension.Eva Unit 01
Yu+Me Dream, the Webcomic (Sorry, I am not gonna link this one) Seriously, raise your hand if you could see it coming. And if you knew before you got to that part of the story, it doesn't count. ~ Dinru
St. Elsewhere, notable because of the theory it makes everything else just a dream too.
Final Fantasy VII is a strange example. Most of the (incredibly complicated) backstory was either really ambiguous or left out entirely, and none of the omissions were explained properly until a decade after the original game was released. So, for anyone who hadn't played the original game in 1997 got to experience the FFVII universe in the correct order, making them wonder why anyone would ever have been confused by the game when they finally get around to playing it only after working their way through the rest of the compilation. All explained in the manual(s)...eventually. ~ Tropers/Kelly, Eva Unit 01
Citizen Kane: Rosebud was his sled. I haven't seen that movie. I don't even know what it's about, or what's so important about the sled. But I not only know that twist, I hear about it again every couple of weeks. And so did you, just now. ~ guyy
Jekyll & Hyde: Nowadays nobody actually realises that the fact that Jekyll and Hyde were the same person was only said in the last chapter and it was supposed to be a shocking reveal. ~ Elgnirp100
Guardians Crusade, in addition to making frequent and heavy usage of this trope, has one specific example which is incredibly played with. Heroic MimeKnight assigned to go collect an emerald guarded by a fierce monster from a rather greedy mayor; as he needs the emerald to pay for the ticket with which he'll set sail over the sea, he agrees to get the gem and return. After a series of sidequests during which he meets a knight, a wizard, and a witch who Knight trails behind right until they get to the boss, at which point just in front of them the traveling party defeats the monster effortlessly and takes the emerald. The party's Exposition Fairy Nehani is rightfully a bit upset, and exclaims that now they'll have to find something else to bribe the mayor with. The reason this becomes a Most Triumphant Example despite looking completely different at first is that while Knight's party's goals are only to get the gemstone and get the ticket to travel across the ocean and the knight does not have those goals (he is instead trying to stop Karmine, an opponent you yourself have to defeat later on), his actions dovetail nicely with yours later on. In addition, if you inspect the beast after the other party has defeated it you'll be able to go into a rather weak Bonus Boss which will earn you the best shield you can get at that point in the game. The options make the trope so confusing in terms of how it's played with that it could technically be Zig Zagged, Subverted, Justified, and Discussed, plus the tons of other times the trope constantly comes into play in Guardians Crusade. ~ Gryzalb
I'll always think of Jane Eyre when I think of anguished love declarations. Jane starts it all off in response to Rochester's aloof dismissal of her, then Rochester catches on and joins in with his own anguished declaration. Then, considering what happens next, it becomes clear just how anguished Rochester's declaration really was. ~ Tropers/Kelly
The Gray Prince, the champion of the Arena in The Elder Scrolls IV: Oblivion. There's so much build-up that when he refuses to fight you and just lets you kill him, it's pretty disappointing. Not only that, but after you do kill him, everyone acts as though you've just completed an impossible task. ~ Tropers/Kelly
General Scales from Star Fox Adventures. The game won't stop emphasizing what an evil guy this dinosaur is. You finally get to the fight against him...and he's told to give back the Krozoa Spirit that he has. He's then killed when it leaves his body. And then you have to fight fuckingAndross. It wasn't even implied that he would show up. At ALL. ~ Earthbound God
A Death Note will kill anyone just by writing their name in it. Just ask Light Yagami. -darkforce392
Swordfish. The film opens with a five minute monologue about how softcore Hollywood villains tend to be, and questions what would happen if a hostage-taker really wanted to get away with it. The same character then proceeds to unapologetically kill a hostagewhen SWAT tries to rescue her. Only, he doesn't just kill her, he blows her up, spraying the surrounding street with 15 pounds of stainless steel ball bearings. Not only is it a Crowning Moment Of Awesome for both the character and the movie itself (and this happens in the first 10 minutes), and a gigantic Take That to every traditional Hollywood villain, it also shows that the film is not afraid to ignore the rules, and that all bets are off. ~ IJustWannaBeGod
Primeval. As of the end of the third series, there are three main characters left from the very beginning. Yes, THREE. ~ Me2
Legend of Galactic Heroes. The true champion of this trope. Forget about Plot Armor. Forget about main characters (yes, that includes the two primary protagonists!) living to see the end. Forget about the idea of notable characters and glorious heroes deserving equally notable/glorious deaths. In this anime, you don't spoiler people by telling them who will die, you tell them who survives. And then consider that this show is one of the triumphant examples of Loads and Loads of Charactersas well.
Resident Evil. Big bore handguns are not as powerful as military grade rifles and grenade launchers, CAPCOM, no matter how much louder they are or how much more apparent recoil they may have. ~ REV 6 Pilot
Pokémon Special. The FLRG arc was a direct consequence of every arc that came before it, and as a whole there's so many Chekolv's Guns, which more than not will turn things around in a different arc. ~ The Violent Tomboy
Robotech, taking together three different series and its three disparate plots, and welding together a semi-coherent universe out of it. ~ Do Know Butchie
"I'll see you in another life, brutha," and its variations. As far back as season one (with Nadia's note) we were seeing these bizarre, seemingly contextless assurances of people seeing other people in another life, and with all those persistent theories of the whole show being the afterlife, the writers were so skillful that they still made it a surprise to everyone that it's the flash-sideways that's the afterlife, fulfilling this series-long Foreshadowing. And this was the most endlessly scrutinized and theorized-about show ever. How do you top that?? ~ ZiggyZag
Persona 4 has a whole collection of them - "I art thou, thou art I" "YOU'RE NOT ME!" and "I am a shadow... the true self." ~ Gorsecloud
Webcomic The Whiteboard, which switched media after 5 strips, and is now over 1800 strips in. A sixth strip on a whiteboard was done as a holiday treat, which means only a tiny fraction of a percent of strips were actually done on a whiteboard. ~ Mr Initial Man
Highlander II: The Quickening. Surely the only work of fiction in history to argue that if the sun were blocked out, the world would get hotter, not colder (and survive just fine, for the most part). -Zuul MF
John Kennish has a car wash. He lives in a mansion, drives a Porsche Panamera and sends his kids to a $20,000-a-year private school. Greg Universe has a car wash. He lives in his '70s van and his kid is being raised by aunts. Y U no make up your mind, teevee? ~ Tropers/Nlpnt
Doctor Frasier Crane, who started out as a one-shot rival for Sam Malone in [[Series/Cheers]], and eventually let Kelsey Grammar tie James Arness for the title of "Longest Time Playing the Same Character on Television".
The Soul Reapers, the Visored, the Arrancar...just take your pick from any of the characters who get introduced in a new arc in Bleach. To put it in perspective: there are four character pages on this website for that manga, three of them for all the characters who aren't the five the series started off with. And they're all long. Only the Arrancar (and two traitor Captains) have died, so fully expect everyone else to come back when Ichigo's powers come back. - afteriwake
Star Wars: "Look Sir, Droids!" got his own EU story and an entry into the original Essential Guide to Characters. Aura Sing started out as the white bald chick watching the podrace in Episode I. All the scum and villainy hanging out in Jabba's Palace? Yep, they've all got names and their own fleshed out backstories, too. And that doesn't even begin to scratch the surface. ~ Space Jawa
Haruhi Suzumiya. Drawing giant alien chalk symbols, smashing Kyon's head into a chair so she can scream her new idea at him in the middle of class, joining and quitting every club in the school before making her own club of people to demand constant attention from, and generally being absurdly bossy and hyperactive at all times; the sky's the limit! Or, in her case, the universe. ~ guyy, ozaniel
iCarly: iStart A Fan War ended with the main character ranting about how Shipping had taken over the in-universe equivalent of the real life fandom, and that everyone should just appreciate the show for the comedy. It was especially galling since the very next episode was entirely centred around shipping.
"Everything I Do, I Do It For You" by Bryan Adams (from Robin Hood: Prince of Thieves) for existing or partly adapted songs (the melody was largely taken by Michael Kamen from a genuine medieval or Renaissance-era tune), "I Am the Wind" from Castlevania: Symphony of the Night for original songs. ~ ZiggyZag
