Usagi talks down Black Lady, who reverts to ChibiUsa in Sailor Moon R. Then she does it again with Nehellenia, and finally Galaxia in Stars. The anime also had her talking down lesser villains on a pretty regular basis.
Tenchi in Tokyo ended with Tenchi telling the villain that he accepts and understands her, and she agrees to put herself into suspended animation until she grows up into a better person. His grandfather had earlier remarked that Tenchi had the gift of being able to solve problems without fighting.
Digimon Adventure 02's Mind Rape-powered Big Bad is Nigh Invulnerable (without the "nigh") and has been kicking our heroes' butts and spreading a sinister black cloud over the world that can't be good. The ultimate battle to save two worlds ensues... no, wait, it doesn't. Instead, the heroes get the kids whose fear he's using to think about their hopes and dreams, resulting in one of the most humiliating villain deaths ever: Various parts of his body disappear as kids say "I want to be a teacher!" "I want to be an artist!" etc. until nothing remains. Then Malo gets blasted and well whining saves the day. The villain in question, Malo Myotismon, got nicknamed "Marsh Malo Myotismon" on numerous boards for this.
The part that made this painful was that the future aspirations of the character seemingly had nothing to do with what had come before in the series. The guy who's currently in a wildly popular (for a) garage band? Yeah, he wants to be an astronaut.
The oddest, funniest part in all of that is when one of the kids said "I wanted to be a comic book artist, but everyone laughed at me so I gave up on it." And another part of Myotismon vanishes! Despite it sounding like a rather depressing comment that should have made him stronger...
Played with in Slayers: Since mazoku feed on negative emotions, Amelia's justice speeches tend to leave Xellos feeling rather queasy.
Used twice in Cyborg 009's 2001 series. 005 uses it against the Spirit of the Earth (in the form of a gigantic jaguar that has been killing people, including the husband of a friend of 005 himself, and both 003 and 009 do that to Sphynx, a super computer who kidnaps 003 to make her his puppet girlfriend and tries to kill the others, specially 009 and 004.
Happens in Naruto itself, at the resolution of the Pain arc. After beating the villain in a fight, rather than killing him, Naruto uses a book written by their shared mentor to get Pain to Heel-Face Turn.
It's also one of the few ways of killing Edo Tensei zombies. If the soul obtains emotional closure, they lose their connection to the physical world and move on, breaking the jutsu.
Naruto does it again with Obito Uchiha. After having torn through his facade as the Ten Tails with fused Kurama and Susano'o, Naruto looked into his mind, saw him daydreaming about a world where he was Hokage, and tore apart all his villainous motivations.
Happened to both of the Big Bads in Mermaid Melody Pichi Pichi Pitch. Gakuto ends up dying in his collapsing castle (voluntary, to "right his wrongs") and Micheal ascends to some kind of Angel-plane, along with the spirits of his fallen minions (who helped Talking The Monster To Death )
In Infinite Ryvius, the Grey Geshpenst completely outpowers the Ryvius and is only stopped when a badly-battered Neya begs Captain Viscuess to stop, and he realizes he can't go through with murdering 500 children. Combined with the events occurring on the Lift Ship at the same time, this is part of an Aesop that words can solve problems that violence can't.
Played with in Mahou Sensei Negima!; after Kotaro joins Negi's side, he starts and keeps bothering Negi about the proper way to fight (fighting for the sake of fighting), prompting Yue to flatten him with a speech. She even feels kinda bad about it, knowing there's no way a kid like him can stand up to her in conversation if she decides to overwhelm him.
Altered slightly in Macross 7. At the end, with the entire galaxy's spiritua about to be consumed by Lord Geppelnich's monstrously transformed body. Basara's singing finally gets through to another Protodevlin, Sevil, and she begins singing. As a result, she starts to produce spiritua within herself, proof that Protodevlin don't need to steal spiritua from others. Geppelnich hadn't believed the process of consuming the galaxy's spiritua to be reversible, but when he starts singing, it and his transformation reverse. Having no longer need to steal spiritua, they then leave the galaxy.
Played with in Fullmetal Alchemist. When Envy makes a desperate last attempt to turn Ed, Roy, Riza and Scar against each other, Ed tells him he's realized the reason he hates human beings so much is his very envy of their humanity. His response is to kill himself. Not a straight example since he was half-dead already anyway and was completely powerless to defend himself, and it was very clear that he wasn't leaving that room alive anyway. He just took what he saw as a less humiliating exit.
Mr. Satan (Hercule in the dub) does this to Majin Buu in Dragon Ball Z. Unfortunately two hunters cause Buu to transform into a more evil form.
Scrapped Princess has the final confrontation between humanity and Providence pivot on a conversation between a woman and a teenage girl. Of course, it also depends on a battle between angels and dragons IN SPACE, so it's not a total letdown.
The subverted version is used in the Climactic mid-wayBoss Battle of the OVA of Record of Lodoss War (which also happens to be the final battle in the first manga, where this trope is also used, since the OVA condensed the story dramatically. Ghim insists that Leylia still exists within her possessed body, and shows a comb he made for her, which allows Leylia a foothold, distracting Karla long enough for the Party to defeat her. Too bad the Sixth Ranger Woodchuck was possessed next.
Magical Girl Lyrical Nanoha: The magical trio of Nanoha, Fate, and Hayate manage to talk the sentient Artifact of Death (who is also a young girl, as these things so often are,) into being friends. This is rather short lived, as said artifact is still an Artifact of Death, and they have to blast the 'Death' part out with an interdimensional warship. Particularly sad in that she asks to be destroyed before she has a chance to regenerate the corrupted section of her programming.
In general, this is usually Nanoha's first course of action when faced with a new villain. They never listen: cue Beam Spam, Out of the Inferno, etc.
Subverted in Souten Kouro. Cao Cao has a whole debate with Li Lie and defeats him with rhetoric... which buys Xu Chu enough time to come and blow his brains out.
Subverted in Paranoia Agent: Mrs. Ikari sits Li'l Slugger down, discusses her life up to this point, and proceeds to divine his true nature and weaknesses... but unfortunately, she's not the one who has to come to terms with him. All her speech does is freak him out and start the destruction of Tokyo.
Subverted in Puella Magi Madoka Magica. In episode 9 after Sayaka became a witch, Oktavia, due to her corrupted Soul Gem, Kyoko desperately looked for ways to revert Sayaka back to being a human. QB told her that to his knowledge no one has ever been able to turn back once they became a witch. He gave Kyoko a Hope Spot by saying that there is no precedent to such thing, and there might be a way which he does not know of. Kyoko then proceeded to befriend and team up with Sayaka's best friend Madoka in an attempt to talk Sayaka back into humanity.Itdid notendwell.
A Certain Magical Index: Touma Kamijo is as fond of doing this as he is punching out the bad guy. Sometimes he does both.
Ouma Yamisaka kidnaps Index and attempts to drain knowledge from her mind so he can lift a curse from a girl, claiming he's only doing it to prove his skill. Touma orders him to stop lying: it's obvious that he's in love with the girl. Touma also explains that he can easily lift the curse and offers to do so. Upon hearing this, Ouma breaks down in tears and surrenders.
Touma asks Fiamma of the Right why he had to go through all the theatrics of his overly complicated plan when he is already powerful enough to destroy the world. Touma then says it's because despite Fiamma's power, he was afraid he would fail. Touma also points out that despite everything that has happened, Touma's friends and even complete strangers have proven that not all Humans Are Bastards like Fiamma had claimed. Touma then punches him out.
When Marian Slingeneyer threatens to draw the cursed sword Dáinsleif and trigger Ragnarok, Touma mocks her and says that if she had the guts to do that, she would have done it immediately. Marian is enraged, but then realizes she is too afraid to actually draw it. Touma then punches her out.
In Flint The Time Detective, Flint or the historian-of-the-day does this to a Time Shifter, whenever they are transformed into their Con forms by Petrafina.
In an issue of The Authority, the villain gets talked into working for the heroes instead of destroying the world. (The heroes give him a run-down country to build up again in an "If you're so smart..." ploy). Note that this is after they've already killed all the soldiers he's deployed, almost all of whom were just teenagers who read his ad in the back of comic books to get superpowers.
Dr. Kriegstein: You're insane. Nobody's going to listen to me. I've ended up as one of those enormous end-of-the-world threats you people have to deal with.
Swift: And this is how we'll deal with you.
Done again with one of the Doc's soldiers, Tank Man. Midnighter realized his adversary had a similar origin story to him and talked him into giving up and going away. They exchanged letters afterwards.
This is a favored tactic of Dr. Leonard Samson who, as a licensed psychologist, often has insight into the inner workings of the Hulk's mind and rage. He's also used this to talk down other monsters and villains, usually while punching them at the same time.
One issue features a rogue general putting his mind into an indestructible monster body. Batman realizes that his brain can no longer process a lot of information, so he begins talking and trying to hypnotize him into falling asleep. Then Superman messes it all up by punching him.
Prometheus also practices this skill. Backed up by technological gimcrackery.
Wild Cats fought TAO, who had a whole range of mysterious powers. Anyone simply talking to him risked going catatonic.
Fables. Playing off '1001 Arabian Nights', Snow White manages to talk her way out of a murder-happy rape-marriage with tales of her friends.
Angel, the canonical comics. Angel tries telepathic spams of Happy Fred Memories to calm down Illyria, who had become depressed over trying to be like Fred and was squashing people. Doesn't quite work and things get much worse.
Captain America, of all people, does this: he manages to talk his ownevil clone into committing suicide. Or self-destructing, since it's not entirely clear whether the clone was flesh and blood or robotic.
This is often Captain Marvel's go to approach if the situation doesn't call for immediate violence, and he's often successful at it.
During a team up with Superman, Captain Marvel was forced to possess Superman's body in order to speak with an ancient frog goddess who was threatening to wipe out a large portion of humanity. Cap is able to simple talk her down using eloquence and sincere, heart felt compassion. The goddess leaves without further incident, and Superman admits that Cap succeeded with words where he would have failed with violence.
A semi-example, but during the Crisis Times 5 JLA/JSA team up, Captain Marvel is able to end the battle between two 5th Dimensional Imps by combining their names into one word, and getting the good Imp present to say it, causing them to combine into a balanced entity.
During a different team up, this time with Green Lantern, they fought a professor who had absorbed the spirit of an ancient Egyptian wizard in order to show people the glories of ancient Egypt. Green Lantern tried and failed repeatedly to just beat the guy into submission. Cap then spoke to the man, pointed out the destruction he was committing not only was destroying some of the artifacts of Egypt (they were fighting in a museum at the time), but he was also going to harm the people he was hoping to show the wonders of Egypt to. The man actually expelled the wizard from his body out of a combination of guilt and shame because of Cap's words.
In a reversal of the above, Cap actually got the invading spirit to vacate a possessed body, rather than talk the host into giving up its power. During Final Crisis, Captain Marvel came across a woman who had become possessed by a demon. Captain Marvel basically glared at the demon and said, "Get out of her. NOW." The demon promptly left without another word.
In The Thessaliad, Thessaly talks her way past a Sphinx and an axe-murderer, distracting the former long enough to escape on a train and distracting the latter long enough to cast a shrinking spell on him and then cleave his head in two.
In Transformers: Last Stand of the Wreckers, it's Played for Laughs when Kup tells a story about how Prowl once spent two and a half straight days lecturing to a captured Decepticon every single chapter and verse of the Tyrest Accord that the 'Con had violated, until the 'Con finally committed suicide out of sheer intolerable boredom.
Taken rather literally in this case; it seems that as of Transformers: More than Meets the Eye #7, newly introduced Decepticon, Tarn, is able to modulate the timbre of his voice in time with the beating of Black Shadow's spark. As he lowers his voice, it causes his unfortunate victim's spark to give up and causes his body to explode.
In Superman: Red Son Brainiac (who is at the moment on Superman's side) determines that someone with Lex Luthor's level of intelligence could convince Superman to commit suicide within minutes. His solution is to eliminate Luthor before he gets the chance.
The Doctor Who comic in Doctor Who Magazine had a story entitled "TV Action!", where the Eighth Doctor and Izzy travelled to our reality. Tom Baker, who had played the Fourth Doctor, defeats that month's alien by merely talking to him and rambling endlessly.
Just barely averted in My Little Pony: Friendship Is Magic (IDW). The Cutie Mark Crusaders drive Chrysalis absolutely crackers, then when she implicitly threatens to eat them, they keep it up until she gets physically ill! None of that, though, staves off the final confrontation between Twilight and Chrysalis.
Apple Pie in the Pony POV Series can do this to certain monsters due to her power as the Element of Laughter. The first time happens, ironically, completely accidentally when she's talking with her 'new friend' Halflight Dawn (who is actually Twilight Tragedy in disguise) and manages to undermine Discord's brainwashing to the point it ultimately enables Twilight to break free and pull a Heel-Face Turn. Later, she manages to wipe out a zombie army simply by pointing out the paradoxical fact that they're apparently dead and alive at the same time. She also manages to convince one of Discord's Mooks to take up knitting in the middle of a battle and blow up a robotic minion via Logic Bomb. However, this doesn't work on Rancor or Discord, due to Concepts being immune to paradoxes.
Men In Black was originally supposed to end like this, but the speech was thrown out in favor of a giant battle. Nobody complained, except the guys that made the giant talking cockroach puppet that never got used.
In the 2003 Peter Pan film, Captain Hook gains the ability to fly using Tinker Bell's pixie dust. Since it operates on happy thoughts, the Lost Boys manage to cause him to sink by convincing him that he is old and alone.
In Star Trek: The Motion Picture, VGER destroys several ships and kills hundreds of people, but Kirk and company discover VGER's secret, and tell it the truth, Decker tells Kirk that he wants to take over VGER (so he can have Ilia as his Love Interest.) VGER merges with Decker and crosses over into another universe and disappears.
Kirk's actually pretty good at doing this to evil computers: it happened four times. In one instance, though, it almost comes back to bite him: deciding it should die, the computer that's taken over the Enterprise shuts down the ship's defenses to allow the fleet to kill it. Fortunately, the commander of the fleet decided to investigate its apparent surrender instead of coming in phasers blazing.
To the point where an adventure for the Doctor WhoRole-Playing Game referred to this as the James Kirk School of Computer Repair. (With explanations that, in this case, it won't work.)
In Logan's Run, when the City Computer recaptures Logan, it uses a Mind Probe to force the person to answer its questions. But, the answers are a major Logic Bomb because the computer cannot accept them, causing this trope.
There IS NO Sanctuary.
The Flight of Dragons ends its epic fantasy quest with an epic debate between twentieth-century writer Peter and evil wizard Omadon. Just when it seems like all is lost and nobody's left to oppose Omadon, Peter discovers he can cancel magic by contemplating the logical rules it breaks. As Omadon boasts, threatens, and finally attacks, Peter counters by explaining in detail how Omadon's magic is literally impossible... rendering Omadon helpless and in agony, and eventually withering away into nothingness. In denying magic, however, Peter ends up banishing himself back to the twentieth century.
Subverted in The Muppet Movie. Kermit the Frog tries to do this to Doc Hopper, appealing to Doc's better nature, but it turns out Doc doesn't have one.
Subverted in Tim Burton's Mars Attacks!. The President's secure bunker has been overrun and his only offense is to give a speech to the Martian attackers. Just like similar attempts seen on screen, it doesn't quite work.
Subject of a throw-away joke in the Jaws-knockoff Alligator, when the heroes are brainstorming a way to kill the eponymous reptile:
"We could introduce him to my mother. She could talk him to death."
Labyrinth: "You have no power over me." - which was the end to a lengthy, melodramatic speech but it actually just was these words that did the trick.
The Marvel Super Heroes CYOA Spider-Man: City In Darkness featured a rather Anvilicious version. Doctor Octopus has embarked on a scheme that will destroy New York. If you (as Spider-Man) try to actually fight Ock, he goes down in less than a paragraph, only for his psychiatrist to chew you out over saving millions of lives. The proper solution is to simply tell one of web-head's greatest enemies that he's hurting people; he immediately stops his evil schemes and breaks down crying.
In Breaking Dawn of the Twilight series, a great battle pitting vampire against vampire is waived in favor of a lengthy discussion. Everyone goes home without a single punch thrown.
Stephenie Meyer:Alice tore a page from The Merchant of Venice because the end of Breaking Dawn was going to be somewhat similar: bloodshed appears inevitable, doom approaches, and then the power is reversed and the game is won by some clever verbal strategies; no blood is shed note except for Irina, and the romantic pairings all have a happily ever after.
Any Discworld book aimed at younger readers (marked "A Tale of Discworld") will likely end like this. A Hat Full of Sky contains a particularly notable example, as Tiffany literally talks the Hiver through to the death it wants.
Played with in Pyramids in that a character talks his way by the sphinx and its riddle by confusing the heck out of it with Ankh Morpork Insane Troll Logic. By the time it's realized something is wrong, he's already started running.
In Robert Lynn Asprin's Myth-Ing Persons, Aahz is being held in a prison which is a magically-animated monster-head. Skeeve frees him by prompting him to tell a string of his old drinking stories, which are so infamously boring the prison-head yawns, allowing Aahz to jump to freedom.
Ayn Rand has a knack for these in her novels, where the climax tends to involve a lengthy philosophical rant against a corrupt society delivered by the protagonist. Howard Roark's comparatively short speech at his trial for the dynamiting of a housing project in The Fountainhead (around 8 pages) simply manages to nab him a verdict of not guilty. By contrast, John Galt's 56 page radio address in Atlas Shrugged ultimately leads to the collapse of human civilization.
Dostoevsky is a tad more forgiving. The finale of The Brothers Karamazov has two speeches, one by the prosecutor and the other by the defense attorney, which combined last only 54 pages. The author even hangs a lampshade on the length of the prosecutor's speech (31 of the 54 pages) by saying he was feeling particularly energetic that day.
Marvin the Paranoid Android is an expert at talking the monster to death by communicating his own depression so powerfully it makes his enemy commit suicide.
On Magrathea (in the books) he kills two policemen by talking in this way to the ship controlling their life support system.
Later, he defeats a sentient armoured tank by asking it to guess what weapon he has been given with which to defend Zaphod against it. When he reveals that the answer is "Nothing", the tank gets so angry that it blasts out the floor, causing it to plummet to its destruction.
There was a dangerous pause.
"Nothing?!" roared the tank.
"Nothing," confirmed Marvin. "Not so much as an electronic sausage."
God gets unmade by virtue of the existence of the babel fish.
How it is such a bizarrely impossible coincidence that anything so mind-bogglingly useful could have evolved purely by chance that some thinkers have chosen to see it as a final and clinching proof of the nonexistence of God. The argument goes something like this:
"I refuse to prove that I exist," says God, "for proof denies faith, and without faith I am nothing."
"But," say Man, "the Babel fish is a dead giveaway, isn't it? It could not have evolved by chance. It proves you exist, and so therefore, by your own arguments, you don't. QED."
"Oh dear," says God, "I hadn't though of that" and promptly vanishes in a Puff of Logic.
However, this causes the Man in question to start following Insane Troll Logic. Case in point: his encore was to prove that black is white. He got himself killed on the next zebra crossing.
In the climax of the (Objectivist) children's novel The Girl Who Owned a City, the title character literally scolds the leader of the opposing group into surrendering and joining her. Keep in mind that this kid is the gun-toting leader of a street gang in a adult-free world, had several cronies around, and was the one who basically acted like a giant Jerk Ass for the other parts of the book.
In The Hobbit, Gandalf achieves a variant of this by keeping the trolls who had taken Thorin and his companions prisoner talking until the sun came up (turning the trolls to stone). Bilbo attempts this to defuse the tension between the elves and men and the dwarves. It doesn't turn out so well. Also, in a milder example, Bilbo learns Smaug's weakness and avoids being caught and eatten by flattering and speaking cleverly with the dragon.
The Golden Age series by John C. Wright has this as a property of the setting—AIs are all inherently ethical, and if you can convince them their very existence is making the universe worse they'll shut down. Similarly, the robots of Isaac Asimov can be coerced into shutting down, the method of which depends on how advanced they are. The early robots in 'I, Robot' could be shut down simply by giving them a decision whose end results, including those caused by inaction, would result in some sort of harm to humans (mental included), a violation of the first law of robotics. Later robots were programmed to choose the lesser harm and could avoid destruction this way, though a sufficiently advanced roboticist could still cause their destruction through a very deliberate and specific conversation. Lastly, (most) robots of all time periods could theoretically be ordered directly to destroy themselves, as the 2nd law, which dictates that robots must obey the commands of humans, supersedes the 3rd, which dictates that robots must enforce self-preservation. However, the robot would need to understand the reasons for its destruction as the difference between the two laws is not terribly considerable.
The best example is "Liar!". US Robots accidentally makes a robot that can read minds, and no one knows how they did it. The three main characters (Susan Calvin, Pete Bogert and Alfred Lanning) are amazed by this. Susan Calvin gets told that a man she likes also likes her back, and Pete Bogert gets told that Alfred Lanning has resigned and left his position for Pete. However, soon they discover it was a lie (the man Susan liked is going to marry another woman he had brought to work a few days before, and Lanning hasn't resigned), and Susan makes the connection: the robot is still bound by the Three Laws, and thus it lied to them so that it didn't hurt them. Susan confronts the robot and provokes a Logic Bomb to it, making it realise that both doing something and not doing something will hurt some people.
A form of this in the X-Wing Series book "Isard's Revenge". The Rogues, in that final battle, tell the clone Isard that she isa clone, and come up with the various discrepancies and memory-holes she must have wondered about which were solved by that knowledge. This leads to a very short Freak Out before she plays dead - which is exactly what the original did. Even if this one wasn't talked to death exactly, she was certainly talked to distraction.
Eddie literally does this to Blaine the Mono in Stephen King's Wizard and Glass. More accurately, Eddie kills Blaine with an unstoppable barrage of really bad jokes. And it is awesome.
In Harry Potter and the Deathly Hallows, the final battle with Voldemort (you know, the one that was hyped up for the entire series?) consists of about four or five pages of Harry and Voldemort talking to each other, then each throws one curse and the battle is over. Well, Harry triesto talk Voldemort into not throwing the curse and repenting his crimes. Instead, Voldemort refuses to listen and casts the Killing Curse at Harry refusing to accept that Harry had become the master of the Elder Wand, which caused said curse to backfire and kill Voldemort instead.
In Neil Gaiman's Anansi Boys, the protagonist scares a dragon away by the nothing he is carrying in his pocket. The dragon happens to be afraid of nothing. Absolutely terrified, in fact.
In the novel Far Away From Us by Michael Uspensky, King Solomon convinces some brigands that "life is futile and is full of sorrows and is pointless to carry on", whereupon they (the brigands, that is) wholeheartedly agree and stab each other. The Hero then inquires if the trick could be repeated with a whole army. The king is uncertain.
In The Silver Chair, Puddleglum manages to break the Green Witch's spell by a combination of burnt-marshwiggle odor and this trope. Ironically, he does so by conceding to everything she's said in her own Breaking Speech, then declaring that even so, he'd rather go on living as if her accusations are baseless than embrace her overly-bleak perspective.
The Doctor would, in a perfect world, talk all his enemies down to a negotiation table and hammer out a ceasefire and trade agreement over tea and cookies. But if that fails, he has this.
The Actual Pacifist Seventh Doctor especially made use of this, notably talking down a Black Dalek this way in "Remembrance of the Daleks"; bear in mind that he has already taken out Skaro and the whole Dalek fleet- he went after the survivor for completeness' sake.
In a far more impressive manner, he talks the god-like "Light" into committing suicide in Ghost Light.
It doesn't need to be a literal 'death', either - he's talked an all too eager sniper into dropping his gun (and out of his eagerness), and kept an Arthurian villain from initiating a nuclear weapon with nothing but words.
Also, in "Silence in the Library" the Tenth Doctor makes the unstoppable microscopic swarm-species Vashta Nerada back off using this technique - "I'm the Doctor and you're in the biggest library in the universe. Look me up.". .
The Tenth Doctor manages to shut down the entire clockwork army in "The Girl In The Fireplace" just by drawing their attention to the fact that he's just broken their only escape route.
Inverted at the end of Series Five: Amy talks the Eleventh Doctor back into existence. Technically she's remembering him, but she just happens to be verbalizing her memories.
The fifth series also gives us the rooftop climax in "The Eleventh Hour" ("I'm the Doctor, and basically... run.").
Fifth series also also offers a massive subversion in "The Pandorica Opens". Facing an army of everything that's ever hated him, the Doctor talks them all into not attacking. However, it turns out that they don't need to attack, since not only are the Roman soldiers with the Doctor really Auton spies, but the thing he's trying to keep them away from is a prison designed for the Doctor himself.
After a while, the Doctor realised that he'd just killed a man with the force of an argument.
It wasn't a very pleasant thought.
An earlier example would be the Second Doctor's companion Zoe reeled out a list of coding and orders to a robot receptionist causing it to break down and catch fire. Even Vaughn had to admit he was "Quite amused"
Angel tries a "we humans are noble creatures who can forgive our enemies" variant during a standoff with the newly reawakened elder god Illyria, but he is interrupted midway though by Wesley, who calmly fires his gun and murders the man who caused Illyria's rebirth. Angel is rather understandably annoyed: "Weren't you listening??"
Played straight with Faith.
The Shadows and the Vorlons were convinced to leave the galaxy after being told off by Sheridan, Delenn, and Lorien in Babylon 5.
It is a little more complicated than that, but not by much.
Another Babylon 5 example — during the civil war between Sheridan's forces and Earth Force ships loyal to President Clark, Sheridan convinces one of the enemy ship captains that Clark's orders are illegal and that he should therefore disobey them. That decision is briefly reversed when the other ship's first officer takes over, and then re-reversed when the ship's crew takes the first officer into custody.
The phrase "Be Somewhere Else" (backed by considerable firepower) convinced a Clark-loyal Earthforce fleet to flee the field of battle.
In the first season, Sinclair talked one Monster of the Week into committing suicide (more or less).
Kirk and Picard are both good at talking monsters to death (AKA fast talking their way out of a jam). Since both characters routinely run into Sufficiently Advanced Aliens who cannot be defeated with firepower, it's an important skill. Kirk tends to be generally less smug when he does it than Picard, though.
Subverted and played straight by the Borg beforeVillain Decay set in, as in their first appearance Q made it explicitly plain that they could not be reasoned with. Played straight in a later episode when Data hacked them through Locutus and electronically told them to "sleep" (at Picard's suggestion of course).
An episode of Honey, I Shrunk the Kids parodied this, when Wayne attempts to talk a home-security computer to death. It appears to work, but then he realizes "that only works in cheesy sci-fi shows!" and the computer springs back to life.
The Quatermass Experiment: Professor Quatermass saved the Earth this way back in 1953. An alien life force had absorbed the consciousnesses of three astronauts, and Quatermass convinced them to commit suicide to keep the creature from reproducing via thousands of infectious spores.
Xander: I saved the world with talking from my mouth. My mouth saved the world.
One episode of Goosebumps had a mud monster chasing two boys. They run into the girl that tagged along earlier. Girl goes on a tangent. Mud monster dries up in the sun.
Hilariously played with in Power Rangers S.P.D.. One Monster of the Week resisted any single try to have him interrogated by the Five-Man Band... until The Smart Guy tries his luck on it. Said Smart Guy is a major Cloud Cuckoo Landerand a telepath who channels everyone's thoughts. In few minutes, the monster is begging to have the guy off him otherwise he'll end up braindead. Not as sinister as it sounds. His rambling drove the bad guy up the wall to the point that he cracked, whereas both threats for if he didn't talk and promises of leniency if he did had failed before.
In the Battlestar Galactica finale, Baltar pulls this off with Cavil, getting him to agree to a permanent peace in exchange for resurrection technology, which the Final Five agree to. Then Galen kills Tory, and all hell breaks loose.
In Day 3, Sherry Palmer does this to a wealthy billionaire who's trying to blackmail David Palmer. The man is old and frail and upset about his wife's infidelity, and Sherry rips into him with an absolutely brutal monologue - so brutal the guy goes into a heart attack. She then holds his medicine out of reach while he dies. Evil? Yes. Contender for a CMoA? Hell, yes.
Similar to the Buffy example up above, in the Day 8 finale Chloe winds up potentially averting World War III by convincing Jack not to assassinate the President of Russia, who ordered the death of Jack's love interest, by getting him to realize that doing so go against everything she believed in.
On Madeline Kahn's appearance on The Muppet Show, she appears in a skit where she is in a park marvelling at how beautiful everything is. Along comes a monster who starts destroying each beautiful thing she mentions. Then she turns to the monster and starts talking about how beautiful it is in its awfulness. The monster starts shrinking from embarrassment until it is small enough for Madeline to hit it away with her umbrella. "Sometimes it helps to talk your problems down to size."
In Warehouse 13 Myka does this with H.G Wells when H.G is trying to destroy the world. In the end Myka makes H.G put a gun to her head telling H.G to shoot her then since everyone was going to die anyway then H.G should just shoot her making H.G realise she can't kill Myka and has a breakdown.
Parodied in twoads by Latin American channel Space, under the appropriate tag line "not everything is solved by talking".
Mercifully free of any heroic platitudes, Roman writer Ovid brings his version of the Greek Mythology of Argos, a hundred-eyed and eternally vigilant watchman. The trickster god Hermes defeated Argos by telling him a series of long, sad, and boring stories until every last one of his hundred eyes shut and fell asleep — and then cutting his head off.
Similarly, Oedipus talked the Sphinx into suicide simply by solving its infamous riddle.
PrincessScheherazade of the Thousand and One Arabian Nights. Her husband, the king, was in the habit of serially executing his wives ... but she kept him entertained with stories night after night, and he couldn't execute her because he wanted to hear how the latest story ended ... until a thousand nights had passed, and he finally decided she was too interesting to kill.
Subverted in a Japanese folktale: a monk meets in a ruin a wicked, cannibalistic hag who's crying because she can't reach Nirvana (being a cannibalistic hag and all). The monk tries to talk to her and make her repent her sins, but the old witch changes her mind and devours the poor guy.
The infamous story of a PC in Paranoia talking the Computer into a logic loop and crashing it.
Most RPGs that have a skill system (read: most RPGs) will usually have some sort of "diplomacy" skill. Judicious use of these skills can often allow victory with very few die rolls and even less conflict.
There are several ways you can do this in Exalted, to the point that most Social charms are built around this trope. A few of them even references the story of Zhuge Liang (see Real Life examples).
In Pokémon Live!, this is how MechaMew2 is defeated. Mewtwo hitting it with Ash's memories give it sentience and an understanding of right and wrong, which it uses to try and take out Giovanni.
In Icewind Dale 2, if you can impress a demon enough by demonstrating knowledge of his kind, he'll leave without a fight. You can also unnerve a Barghest and its brood (provided you didn't kill him earlier) from a fight by showing him the dead kitty you've been carrying around for no reason since the beginning of the game. If you also happen to be carrying a dead man and a dead woman (and have enough ranks in Intimidate), the Barghest will run off in fear because someone as deranged as you clearly isn't to be messed with.
Yquog: You... I... But... By Iyachtu Xvim, you're SICK! You hold no concept or understanding for things alive or dead! I want no part of you, not when I'm so close to maturity! Collect all the bodies you want, sick fleshy mortal, but you'll not have mine! I'll leave this place, and you, in peace and never return, of this I swear! Player Character: Oh, well, okay, if you insist. Pity, though, you'd have made a fine addition to my pretty, tender collection... Yquog: AAAAAAHHHHHH!!!
Planescape: Torment allows the player to literally talk some NPCs to death, including the final boss, and avoid many other enemies or dangerous situations merely by virtue of having a high enough Intelligence, Wisdom or Charisma. This is largely because its world is shaped by belief.
And in the case of the final boss, it's an aspect of the hero himself. Convincing it to rejoin with him whether by threats, trickery, sincerity, or force of will results in a somewhat better ending than simply destroying it.
In what is probably the Crowning Moment Of Awesome for this game, the last case of Phoenix Wright: Ace Attorney: Trials and Tribulations has Mia Fey talk the spirit of Dahlia Hawthorne past death, forcing her to recognize that all her plans have ended in failure and apparently condemning her to an eternity of regret. Dahlia's ensuing rage forces her out of the body she's been possessing with a scream of frustration. Let's just say the Judge was not the only person freaked out and awed.
Of course all the 'battles' in the game are won by doing this. It's never enough to prove your client is innocent, you have to meticulously unravel the lies of the true murderer through the careful application of contradicting evidence and basically force them into a confession. Somewhat justified, as, in the real-world Japanese legal system, many defendants would have already confessed, courtesy of intense interrogation techniques.
The Fallout series is famous for this. In almost every game you can talk the Big Bad down by just telling him how stupid his plan is.
In Fallout 1 (from the makers of the Planescape game above), the final boss could be beaten like this. If you can convince him that his plans are utterly futile, he'll initiate his base's Self-Destruct Mechanism and let you run to escape.
The final boss of Fallout 2 could not be directly talked to death, as no matter what you say he dismisses all your claims and will eventually attack. However, you can talk to his bodyguards and ask them to side with you against them, and you can also reprogram the automated turrets in his chamber to attack him.
In Fallout 3, you can talk down Eden and Autumn (well, Autumn doesn't die but just walks away) in the main quest by pointing out that they've either already lost or that they can't even keep order in their own organization and have no chance at taking over the wastes.
Fallout 3 again, in the add-on Operation Anchorage, the last boss in the simulation kills himself if you pass the speech challenge. Once again, you do this by pointing out that his army is dead and his fortress is surrounded by power armor wearing American super soldiers.
Fallout: New Vegas lets you convince Legate Lanius to pull back the remains of his army and retreat... if you have a Speech skill of 100. Depending on the dialogue path you take, you either bluff him into retreating or point out that this army has no chance of conquering the New California Republic even if they somehow take Hoover Dam, due to their horrific logistical situation.
You can also pretty much talk down 99% of all non-random fights.
You can talk down Ulysses in the Lonesome Road add-on for New Vegas by using his own philosophy to single him out as a hypocrite.
Ditto the Think Tank in Old World Blues.
Salt-Upon-Wounds from the Honest Hearts add-on for New Vegas can also be talked down, but only in one of the two ending quests. Otherwise, he is unceremoniously executed or runs away on his own.
A variation occurs in the Hordes of the Underdark expansion for Neverwinter Nights. If you managed to get Mephisto's true name right before the final battle with him at the end of the game, you can use it to stop the fight before it even begins. This only works if you have his name, and with it you can do different things based on your Character Alignment and conversation options you choose, such as: order him to drop dead, order him to return to Hell, or even order him to give you command of Hell and become your either you partner or lackey. Your choices have major effects on the epilogue.
In Neverwinter Nights 2 you can convince a demon that merely by talking to you, it has failed in its assigned task to knock down a door, and has failed its master. Since failing its master is punished by death, it promptly keels over.
In Star Wars: Knights of the Old Republic II, the only way to defeat Darth Sion is to talk to him in the breaks between combat. Eventually, you succeed in weakening his will to live, at which point he accepts death peacefully. Roughly:
Exile: Sion...your life...was it worth living?
Darth Sion: It was not. No matter how many Jedi I killed...no matter how many lay broken at my feet...the pain would not end. I am glad to be rid of this place.
In the Neverwinter Nights community module The Bastard Of Kosigan, your character gets to hold a conversation with your recently deceased father's ghost. Not forgiving him makes him take damage, but you can choose to forgive him completely and avoid the battle at the end.
In Mass Effect 1, you can talk your way out of a few fights using the Charm and Intimidate skills. You can even convince the Brainwashed and Crazy Saren that siding withSovereign will save nobody. Though being convinced that Sovereign can regain control over his mind and body at any time, he pulls out his gun and shots himself in the head.
In Mass Effect 3, the Illusive Man can be made to realize that he too is indoctrinated and his actions are doing far more harm to humanity than good. He eventually admits the painful truth and chooses the exact same solution as Saren did... if you got all the pertinent reputation checks while talking to him throughout the game. It only works through Charm options, though.
Inverted in one chapter of Disgaea, where the monsters, knowing that Laharl is Allergic to Love, bombard him with happy and cheerful sayings, sapping his powers for the duration of that battle.
Amused by this, Flonne even joins in with her happy message of eternal love. The irony of the moment is that Laharl wouldn't have been impaired (as badly?) had Flonne NOT joined in. The monsters are just saying it, Flonne REALLY believes it.
The Mediator class in Final Fantasy Tactics has the "Death Sentence" skill, which kills its target in three turns if successful.
There is also the much milder skill "Mimic Darlavon" ("Daravon" in the previous localization,) which simply puts the enemy to sleep by droning on and on and on, like the tutorial-dispensing Professor.
Final Fantasy Tactics A2 has a Clan Trial where you need to chase off some monsters. Not with spells and swords, but picking the right interaction (stare down, threaten etc)..
Earthbound Zero/Mother: In the final battle, Giygas cannot be physically harmed. In order to beat him, Ninten and his party must sing the lullaby once sung by Giygas' human mother. Unable to cope with his emotion, Giygas flees the planet.
Earthbound/Mother 2: Giygas has gained so much power since the last game that he is now a mindless Eldritch Abomination. It is impossible for the Chosen Four to physically harm him because there's nothing physical to harm. Instead, Paula must use her near-useless Pray ability to summon the aid of everyone they met on their journey, even the player. Overwhelmed by emotions, Giygas is vanquished.
Mother 3: Heartbreakingly subverted. The final boss of the game is The Masked Man - formerly Lucas's brother, Claus. Lucas cannot bring himself to hurt his own brother, so he must guard and heal himself until his mother's voice tells them to stop fighting. Claus, no longer Brainwashed and Crazy, commits suicide to stop Pokey's influence over him, and dies in his brother's arms.
Early on in Baldur's Gate, you can encounter an evil cleric named Bassilus and his army of skeletons and zombies. If you pick the right threads in the Dialogue Tree, he loses control over his undead minions and they all fall apart, making the fight against him that much easier.
In the sequel, you eventually meet an Spectator (a non-evil Beholder) who is magically bound to guard a box containing an item you need. The most obvious solution is to kill him, but with a high enough Wisdom you can point out to him that the wizard bound him to guard the box, not the ''contents'' of the box. . .
In Flight of the Amazon Queen, you encounter a gorilla blocking your way; you can get rid of it by telling it that it doesn't exist. (And even if it existed, it has no business being in South America when gorillas only live in Africa.)
Alpha Protocol has a lot of situations where talking to the right people beforehand can make certain fights much easier (for instance, being friends with Steven Heck can make Brayko a lot easier to fight), but the only boss fight you can outright talk your way out of is the rematch with Conrad Marburg if you didn't kill him in Rome, which requires high reputation or the piece of evidence that proves Parker was the one who cut him loose during his Deus Vult days.
In Dragon Age: Origins, wandering through Denerim's market may lead you to being confronted by a royal knight who fully believes Loghain's lies that the Grey Wardens murdered the king (It was really Loghain leaving him to die) and demands that you face him in honorable combat. With a good persuasion skill, you can make him question why the Wardens would want the king dead, and, unable to think of an answer, he agrees to back off.
Deus Ex: Human Revolution gives you the opportunity to use diplomacy to overcome some situations. Unfortunately, the main bosses can't be beaten this way.
There is a nice final boss fight beforehand, but this is how the Big Bad Lambda in Tales of Graces is ultimately defeated. Following Asbel's eager Patrick Stewart Speech, Lambda agrees to give humans a chance, merges with Asbel, and becomes dormant.
In Star Wars: The Old Republic, at the end of the first act of the Imperial Agent story, the agent can do this to the Big Bad by pointing out that a) his plans require his/her cooperation, which (s)he's not going to give and b) if he kills him/her, his/her allies will retreat with knowledge of his identity and plans, which will bring the Empire and Republic alike down on his head. Left with no winning play, the Big Bad surrenders.
In 8-Bit Theater, Black Mage killed Astos by making a really bad joke.
Astos? Mo' like yo' ass is toast!
As Puff of Logic illustrates, Red Mage once defeated a T-Rex by telling him he couldn't exist.
He TRIED to do the same earlier in the comic with a giant, citing the various environmental and physical reasons that make giants impossible to exist. The giant proved his existence via club to the face.
And now it looks like "Warbleck" is off to vaporize itself thanks to a five-man Logic Bomb.
This was also their final plan for fighting Chaos. They intend to have Fighter talk to him. As Fighter seems to just make people stupid by talking to them, the plan is to make Chaos Too Dumb to Live.
Red Mage: We can't out-fight him, we can't out-cast him, and we can't out-think him. But we can out-stupid him.
In fact, White Mage does this with Chaos by convincing it that the nothingness that would ensue from destroying all life would be a form of order itself.
In this comic of The Order of the Stick, Vaarsuvius puts a horde of goblins to sleep by delivering an endless monologue about the earthshaking feats of battle magic which are about to be unleashed on them…
Haley: Good job, Vaarsuvius! Your spell put the goblins to sleep! Vaarsuvius: But… I did not cast my spell yet…
In The Inexplicable Adventures of Bob!, Bob does this very well, to the point that it can probably be considered his most effective weapon. It's how he stopped Fructose Riboflavin once, the Bigfoot Army, and Galatea. Though the second time he tried it in Riboflavin, it backfired. The second time Galatea's megalomania flared up, it only took him one simple sentence to help her see her plan wouldn't really fix anything, prompting her to lampshade his skill with using this trope.
It also has a perfectly straight example when The Shadow Child aka Disbelief got defeated when Javert, The Cynic of the series, delivered Silly Rabbit, Cynicism Is for Losers! summation by stating that even he wishes sometimes to believe.
In Captain SNES, Frog, Palom and Porom defeated the Eater of Dreams during a conversation. He was giving his big speech about how the heroes have no chance and the heroes were saying how much of a cheating bastard he was or how he could not win, but the EOD ends up dying because he wasn't paying attention to his HP and ran out of hit points due to a previously cast Virus spell.
Yami: Indeed Tea, it looks like we had more in common than I thought.
Also parodied when Tea is dueling Mai Valentine and gives constant friendship speeches during nearly every sentence she says, which causes Mai to give up just to shut her up.
Played for laughs in Naruto The Abridged Series by the Third Hokage against his fight with Orochimaru. When confronted by reincarnated forms of the previous two Hokages, he performed one of his strongest techniques: "The Old Man Monologue Justu". No, seriously.
In the episode "Born Again Krabs," this trope is spoofed when Mr. Krabs greedily trades Spongebob for 62 cents, thus sending Spongebob to Davy Jones's locker (the equivalent of Hell) for eternity with the Flying Dutchman. A few seconds later, the Flying Dutchman returns Spongebob, stating that Spongebob talked too much and that it was driving him crazy. This cuts to a scene of Spongebob babbling about his life rapidly and non-stop while the Flying Dutchman looks exasperated.
In the episode "F.U.N.", Plankton disguises himself in front of a magic shop when SpongeBob shows up. He doesn't recognize him at first, but when he sees the magic shop, he starts gushing about a magician he once saw. Plankton finally has enough of his glurge-filled rambling and gives himself up.
SpongeBob: Plankton! It's you! Plankton: Yes, and all this time I thought I was the master of torture. But that... that just wasn't fair!
One episode of The Powerpuff Girls had Blossom and Buttercup arguing over whether to use tactics or brute force against a monster. Bubbles solves the problem by simply asking the monster to leave town, pretty please with sugar on top. On the other hand, Blossom and Buttercup keep trying to prove that their way works, even when it's obvious that they don't. This actually might explain why the monster finally left when Bubbles asked - when the argument leads to Blossom and Buttercup making one final attempt to prove that their way is the right one, the monster is◊ annoyed that the girls are still trying to beat him, and was probably glad for the excuse to go.
Subverted in "Treehouse of Horror" in which a haunted house seeks to force the Simpsons out. After a Can't We All Get Along? speech from Marge, the house thinks about life with the Simpsons, and chooses to destroy itself in a scene reminiscent of the finale of Poltergeist.
Lisa: It chose to destroy itself rather than live with us. You can't help but feel a little rejected.
Subverted in "Treehouse of Horror VIII". Marge gives a heartwarming speech to a mutated mob that calms them down long enough for Marge and kids to get into position and blast them away with shotguns.
In the He-Man and the Masters of the Universe (1983) episode "Daimar the Demon," the title character believes he is predestined to destroy Eternia. He-Man makes the giant monster realize that he has free will and doesn't have to be evil, and so Daimar chooses not to hurt anyone after all.
In an episode of Invader Zim, Dib uses his newly gained super powers to dodge Zim's defense lawn gnomes (which he could have easily done without powers) and talk to Zim at his house.
Dib: I've got some stuff to say to you Zim. (Fade out and fade back in hours later.) And that's all I have to say about that.
Zim: Well, Dib, Your words have moved me. I'm done with evil. Gir, it's been a pleasure working with you, now self destruct.
In Batman: The Brave and the Bold, Equinox wants to reset the universe, as he wants to make order and chaos balanced. After a short talk with Batman, he realizes that he's too chaotic to make a fair judgment on reality.
Fluttershy Takes A Level InBadass Adorable in "Dragonshy", and confronts a dragon this way just as he's about to smash her friends. She does this again in "Stare Master" against a cockatrice as she's being turned to stone.
The Real Ghostbusters Halloween special, "The Halloween Door". A Halloween-hating Moral Guardian has created a machine that destroys all evidence of the holiday; Jack-O-Lanterns, costumes, candy, decorations, etc. Unbeknownst to him, doing so breaks an ancient contract with the spirits of the netherworld, who agreed to leave Earth if they would be remembered, which led to the holiday. The monsters return and cause havoc, and the Ghostbusters are powerless to stop them. Until a little girl offers to help them, revealing that she isn't afraid of the monsters. The Ghostbusters have her walk up to the lead kaiju, request candy, tell him he's funny, and demand a Halloween story. This reveals that the actual point of Halloween (teaching children not to be afraid) is still alive and well, and forces the monsters back into the netherworld.
In the ep "Patriot Act" a bunch of second-string Badass Normal heroes go up against a rogue general who shot himself up with Super Serum to prove that superheroes/metahumans are a threat to normal people. When the heroes go down, the civilian population intervenes, informing the general that he's the only one in the battle who actually has super powers. "All right, I've become what I hate, I'll give you that," the villain says, putting down the car he was about to throw, and departs.
In "Flash and Substance," the Flash sits down at a bar with the Trickster, chides him for not taking his medication, and persuades him to both give away the other rogues and turn himself in by promising to play (soft) darts with him in the hospital.
Transtech Shockwave: And don't even think about deactivating yourselves. You don't want to see the paperwork for that.
The Optimus Prime of Transformers Prime would often try to play this straight (mainly with Megatron, Starscream, Skyquake and his brother Dreadwing, he even tried it on Unicron), results would often vary depending upon whom he was speaking to at the moment. The brothers at least paused to listen due to their sense of honor, while Megatron and Starscream would have none of it. Prime was at least able to stall the latter by genuflecting before him.
In an old animated short on Sesame Street, the Western town of Sniddlers Gulch is terrorized by Cowboy X, a huge bruiser who rides around town using an ink stamp to mark random things with a letter X. One small boy finally tries asking Cowboy X not to do that. Cowboy X actually agrees to stop. In a subversion, he immediately changes his name to Cowboy O, and rides around town stamping things with the letter O. In a double subversion, the people of Sniddlers Gulch are satisfied with this.
Freakazoid! manages to convince one-off villain the Nerdator that his plan of kidnapping nerds to steal their brainpower will make all girls avoid him. So he decides to kidnap "good-looking but vapid air-heads" instead to steal their good looks, and according to the narrator, no one cares.
This is basically the definition of a filibuster, where the "monster" in question is a bill that a legislator wishes to block. The record in the U.S. is held by Strom Thurmond, who rambled on for more than 24 hours to block the Civil Rights Act of 1957.
Ironically enough, it was subverted in its very first use during the Senate's meeting over the issue to reverse the censure placed on Andrew Jackson. The opponents to reversing it simply began to talk on and on. The Jacksonian faction's response? They simply stocked up on food, ale and coffee and enjoyed themselves until the opposition gave up.
In America at least, the ability to use a filibuster to halt the passing of a bill became so annoying that it was decided that any use of it could be overridden by a 60% majority simply because pretty much anyone could delay a bill and piss off everyone just by talking for a long time.
Still played straight in Britain, but with a twist: Because the rules of the British Parliament say that an MP must make points germane to the topic, the usual US tactic of rambling on about anything (derisively referred to by British parliamentarians as "reading the phone book") is not available. The record for managing to spin reflections on a single topic is eleven hours.
One tactic, such as that suggested for enshrining a promised referendum on the EU in 2017, seems to be tabling excessive amounts of amendments to a bill in order to ensure it runs out of parliamentary time.
Zhuge Liang has a knack for this. He once challenged Wang Lang to a battle of words, and when Zhuge finished verbally lobotomizing the reasons for Wei's political moves, Wang Lang DIED. Same thing happened with Cao Zhen, but with a LETTER. In the exact words, "Cao Zhen became furious, coughed, and spat blood..." If only Zhuge Liang could have a little chat with all his enemies...
