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 thinks 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, and each troper gets one example per trope, no more. Also, don't go "no, this is," or phrases like that. This is about our own personal favorites.
Alien 3's Dillon. "You're all gonna die. The only question is how you check out. Do you want it on your feet? Or on your knees... begging? I ain't much for begging. Nobody ever gave me nothing!"
"No, sir, we are dressed in our best and are going down as gentlemen... but we would like a brandy! ~ sardns
The Order of the Stick numerous times. Ninja goblins in plain sight that an entire party misses, huge gates that the Monster in the Darkness can't see, and many more. ~ Zfish9
The Nostalgia Chick business with her and Nella. How many times do Lindsay and Nella have to say that they don't act like that and are best friends in real life? - emeriin
The Minecraft "fans" who CRASHED THE SERVER because updates were going to be slow that month. ~ Tails2000
Zero Punctuation. I've never played the game and I sure don't plan on it now, but that review was dead on as always, Yahtzee! Thanks for saving me the effort of forming my own opinion! ~ Gfrequency
Final Fantasy. When it comes to the games, it's at the point where it's difficult to tell the difference between a legit criticism, and hate fueled by the Nostalgia Filter. ~ Cyber Tiger 88
Even the author admits that Harry/Hermione shippers are "delusional".
Nanoha."The White Devil". That particular nickname has become so ingrained into the fandom that one sometimes has to remind oneself that it isn't canon. ~ Excelion
About half the characters in Bleach. Mostly for the captains, though. And many of them are hilarious. ~ Sgt Frog 1
Touhou: The land of Gensokyo, where if people believe it doesn't exist anymore here, it does there. - SonicGTR
Pick any book in The Secrets Of The Immortal Nicholas Flamel. For a start, there's Roman, Celtic, Nordic and Egyptian mythology, vampires, werewolves (and other were-clans), dragons, alchemy... You name it, it's probably there. ~ Icefyre Storm
Sergeant Kal Skirata in (Darth) Karen Traviss' Republic Commando books. Many of the character frequently refer to him as Buir: Mando'a for "mother/father/parent." ~ Tricky Pacifist
Zachary Foxx - show this trope to a Galaxy Rangers fan and watch them start snickering. He's the most blatant about it to the youngest two Rangers (Niko and Shane) who don't have parents. ~ Allronix
Eternal Sonata, when Claves dies... I mean, it only takes about ten minutes before she finally kicks it. ~ Eriyu
Metal Gear Solid 4 can one-up that: Big Boss gives a twenty minute long speech after being infected with a virus that's supposed to kill with a heart attack instantly.
Sniper Wolf from the first Metal Gear Solid wins the Final Speech prize for delivering said speech immediately after specifically telling you she was shot in the lung. ~ Jesska
"You're the entertainer" He said in the same way someone would say "You're a motherless piece of scum and you raped my dog" "Felix Castor" I agreed, completely deadpan "I roll the blues away" ~ Metalbane
Seeing as the first one listed here is a tie, this one will be for Kyon only. ~ Zfish9
Static Shock. He was already a pretty cool and respectable superhero, but when he jumps to the future and meets his adult self...well, damn. ~ deeman45
Mikuru. She grows up, and helps Kyon fix the timeline after the incident in Vanishment. There's a point in time where there's 2 Yukis, 4 Mikurus and 3 Kyons existing at the same time, with most of them standing/lying near North High's gate.
