This Is Unforgivable!

"Muzan Kibutsuji! I'm not letting you get away! No matter where you go! No matter where you go, you're not getting away! I'll follow you to the ends of hell, and I swear I'll slice off your head with my blade! I'll never forgive you no matter what!"

- Tanjiro Kamado

Someone might be the kindest, most laid back person in the world, but sometimes even they get pushed too far. Then they say "This is unforgivable! " and the audience knows that an asskicking of epic proportions is about to start.

To the western ear, it seems quite anti-climactic and quaint, but to the Japanese, this is strong language. It is the Challenge, and it is rarely defeated. Specifically, it has to do with a notion in the Japanese culture of narrowing possibilities; if the subject can't be forgiven for a transgression, then the only other option is that he's about to get his head ripped off or otherwise punished in a severe fashion. And the person who can't forgive won't give this up. Back in the era of the Samurai and the like, this had even more teeth since the person who made this challenge very likely would chase you to the ends of the earth for revenge. Basically, it's only said to someone who (in the speaker's opinion) has crossed the Moral Event Horizon, but also entails a burden: the speaker is so offended that a Roaring Rampage of Revenge is the only option. Obviously, it can overlap with Pre-Ass-Kicking One-Liner, so expect serious butt-kicking in the following Right Makes Might fight.

"I will make you pay!", "I have had enough of you!", "This Means War!", "You Monster!", "I'll Kill You!", "Your life is forfeit!", "You don't deserve to live.", "I'll get you for this!", and "Prepare to Die!" when used in dramatic situations are about the only Western expressions that come even close to what This Is Unforgivable! means in Japanese.

It is also used as a way of pointing out to the audience how evil this guy is—that he completely beyond Forgiveness and redemption. Particularly if the character being issued the challenge has crossed the Moral Event Horizon, so that the main character can freely kill them without Fridge Logic causing them to wonder if that was really necessary. Similarly, it can also be used to point out how stupid the guy is, seeing how they proved to be just plain Too Dumb to Live. Naturally, anyone stupid enough to make that someone hit him / her with such a phrase is bound to feel rather guilty.

Much like Giving Someone the Pointer Finger, this is becoming something of a devalued expression through overuse; it's prone to being bandied about lightly or overused, or for the hero to change phasers from "kill" to "massage" once they beat and befriend the Easily Forgiven villain. This tends to break the emotional impact of "This Is Unforgivable!"

In a classic fashion, villains are also quite fond of using this trope whenever everything is going wrong thanks to those puny heroes. Sometimes after they say "This Cannot Be!" and afterwards saying that they will return and such, they can be found saying this as a way of expressing that they will return for revenge against the heroes. Much like said trope, "This Is Unforgivable!" can also sometimes even be a sign of either a Heroic BSOD for a heroic character or a Villainous Breakdown for a villainous character.

Sometimes phrased as "I'll never forgive you." See also The Coats Are Off.

Anime and Manga
"Kouji: Because of you... Many people have died... THAT IS UNFORGIVABLE!"
 * Whenever Kouji Kabuto of Mazinger Z said this sentence, you knew he was REAL angry, and someone was going to be summarily trashed in the near future. A good example was in the manga, after he learnt Dr. Hell had created a weapon that was able to nullify gravity... and had tested it on an entire city. Another two memorable instances happened in the Mazinkaiser movie (Mazinkaiser vs Great General of Darkness: at the beginning, after Lori and Loru's, and at the end, right before he :

"Domon: You'll pay for this. There's no way I'll ever forgive you!"
 * This sentence was also used fairly often by Baron Ashura (to Kouji and his friends after being defeated) and Dr. Hell (to Ashura after his servant botched still another operation).
 * Tetsuya Tsurugi of Great Mazinger and Duke Fleed of UFO Robo Grendizer also followed on the Kouji's steps.
 * Yomiko of Read or Die says this as she breaks down and sobs in an incredibly Tear Jerker scene in the OVA after.
 * As one of the oldest examples in Shonen anime (in fact, the show that kicked off the Shonen fighting genre), Kenshiro of Fist of the North Star often only broke his understated manner of speech to deliver this line, or a line to this effect, to some bad guy who went too far in Kicking The Dog, often followed with something about how there wouldn't even be bones left after he was done with the offending party. After saying it, he would kill the person he said that to. Even if Defeat Means Friendship and the antagonist turned out to be noble all along.
 * Sailor Moon:
 * Used often in Sailor Moon's In the Name of the Moon speech.
 * Other Senshi also use it as well, specially Rei/Mars and Ami/Mercury  in the R season.
 * A particularly effective one of these was uttered by Makoto/Jupiter, just before destroying Falion with her Supreme Thunder attack.
 * A baddie also uses this; namely, Nehellenia in the penultimate story arc in the anime, when Galaxia tricks her into unleashing a nightmare by repeatedly muttering "Unforgivable" until a mirror appears from her heart. She then shatters it, unleashing a curse onto Tokyo.
 * Tenchi's mother in The Movie, Tenchi Muyo! in Love, utters this. Yeah, up to this point, she was the Ordinary High School Student, and Kain was a Sealed Evil in a Can that nothing else in the universe could defeat. Doesn't matter.
 * Haruka in Noein once she really starts getting pissed at the villain. It took the entire series for her to get to this point, and she had been accepting of nearly everyone else's Jerkassness.
 * Goku of Dragonball Z generally delivers this line to villains who went too far with Kicking The Dog, but tends to forget about it before the fight is even over (both Vegeta and Frieza were allowed to leave unharmed alive).
 * The Frieza example was more of a case of Cruel Mercy on Goku's part (considering Frieza was Half the Man He Used To Be at this point courtesy of his own energy disc), followed by blasting him to hell when Frieza made the mistake of trying to blast Goku In the Back as he was trying to leave (though Frieza did get better).
 * Taken to the next level in the last fight of the Cell Games arc. Cell went out of his way to make sure Gohan was well and truly pissed off, finally killing the gentle giant Android 16, to let out Gohan's whole power. It worked.
 * Also happened earlier in Dragonball when Tambourine killed Krillin. Unlike Goku's later This Is Unforgivable! moments, Goku actually kills Tambourine purely for revenge.
 * This results in Piccolo subsequently invoking the trope.
 * Judai of Yu-Gi-Oh! GX is fond of this phrase when It's Personal, i.e. finding out his mentor is a Treacherous Advisor (working for the Big Bad, okay, not too nice—but betraying his trust = unforgivable).
 * This is also a common utterance for the heroes in the original Yu-Gi-Oh (not the Toei one). Offending Yami on a moral/emotional level is not good for your health.
 * Happens so often in the original manga its practically Yami's catchphrase. Whats especially hilarious is when he does it several ties to the same person.
 * Jojo says this to Dio in JoJo's Bizarre Adventure after learning that Dio's minion brutally killed his dog.
 * Chichiri of Fushigi Yuugi, rarely angry, furiously unloads this statement on a group of warriors who are about to disgrace an ally's sacrifice. Wisely, they back down.
 * Used in Naruto during the Retrieve Sasuke arc. Jirobo made the mistake of insulting Shikamaru, then fighting Choji, who considers him his best friend. He shouts the trope and wins the fight. Seriously, don't ever insult Choji's friends.
 * Tsunade says this to the six paths of Pain after they level Konoha.
 * Naruto himself is also clearly thinking this.
 * In the "Fire Temple" Filler arc, Sora tells Kazuma he won't forgive him if he insults his father again. However, Kazuma's response is "You won't forgive me? So what?!"
 * Don't forget Naruto's fight with Gaara. Towards the end of the fight, he screams "I've HAD IT with you!" (in the anime) and head butts him. Later on, when both are too weak to even get up, he attempts to crawl ON HIS CHIN and defeat Gaara.
 * Naruto says this to Haku after he "kills" Sasuke.
 * Kakashi has this reaction to Kabuto raising the dead and forcing them to fight for him.
 * Bleach:
 * When Rukia is being arrested, she tells Ichigo that if he comes after her, she will never forgive him. After some complaining, however, she comes to terms with the idea of him helping her.
 * One of the earliest was when Orihime destroys the Numb Chandelier, after first declaring "I will never forgive those who hurt Tatsuki!"
 * After Captain Komamura yells this at, he proceeds to immediately bring out his Bankai and asskicking ensues. His ass, that is.
 * Captain Jobb- No, his name's Captain Hitsugaya, sorry- utters this at a few scenes earlier, in response to . Hitsugaya then gets worked.
 * Ishida utilizes it during an internal monologue as he's facing down Mayuri Kurotsuchi, although he's apparently gotten over it by the end of the Hueco Mundo arc.
 * Mayuri too had one against Szayel Aporro Grantz. Szayel claimed to be perfect and Mayuri derided him for it, as a man of science would be rendered obsolete by perfection.
 * In the English dub of anime episode 144, one of these occurs when Ichigo, Chad and Uryu Ishida fight two Arrancar in Aizen's palace in Hueco Mundo. Ishida says that the less human Arrancar look, the less intelligent they are. One of the Arrancar does not take this well and tells Ishida so. In a subversion, Ishida proceeds to destroy him in the ensuing fight.
 * Charlotte Cuuhlhourne repeatedly screams this after Yumichika damages his hair.
 * Barragan says this multiple times after all his Fraccion have been killed. It is unclear if he is angry at the captains for killing them or if he is angry at the fraccion for making him get off his ass and participate in the fight.
 * Similarly, Captain Yamamoto says this to the vice-captains when they need his help to destroy Allon.
 * He earlier tells Kyoraku and Ukitake that while he's willing to allow his other men to track down and kill Renji for saving Rukia from her execution, their dishonoring their position as captains is far more severe and forces him to deal with them personally. He also seems to take it personally that they were the ones to sabotage the execution, if his boasting about the pair is anything to go by; it's 'unforgivable' not just as his subordinates but as his favourite students.
 * Ichigo says it to Kumoi (who's holding Lurichiyo hostage) in anime episode 186.
 * After Tousen outlines his grievance against Kenpachi for killing the previous captain of Squad 11, Kenpachi asks if Tousen hates him, Tousen responds in the dub by saying that "(he) simply find(s him) UNFORGIVABLE!" (and says that Kenpachi is "beyond redemption" in the English version of the manga) before releasing his bankai.
 * Subverted in anime episode 198. During the fight between Espada #7 (Zommari Rureaux) and Captain Byakuya Kuchiki, Rureaux says it to Kuchiki after Kuchiki uses his bankai on him. Captiain Kuchiki then proceeds to effortlessly deflect Rureaux's special attack and destroy him with a single blow.
 * Anime episode 204. Princess Lurichiyo and her servitor Kenryu have a falling out over Kasumioji clan policies. To heal the rift between them, Ichigo and friends pretend that Kenryu is going to commit suicide in shame. Lurichiyo falls for it, but Kenryu blurts out the truth and Lurichiyo tells Ichigo and the others that what they did was unforgivable.
 * Anime episode 243. Yumichika says it to his zanpakuto's manifested spirit Ruri-iro Kujaku while fighting him.
 * Kagome from Inuyasha has this reaction when Manipulative Bastard Naraku stages a Xanatos Gambit designed to turn the True Companions against Sango and/or corrupt her by forcing her to kill her mind-controlled little brother and/or kill them all by luring them into a castle full of poisonous miasma. She locates him by the fragments of the Shikon no Tama he has, and fires a purifying arrow at him. Which blows through a building outer wall, dissipates the toxic miasma, and blows off his arm. He is so stunned he just stands there while she fires a second arrow at him, which reduces him to a head. After that he flees, and it's a long time before he dares face her again. She's actually so pissed off that the mere beginning of her "I won't forgive you"-like declaration features a whole page and follows for several pages.
 * Negi uses it the first time he confronts Fate Averruncus, this is a subversion, since Fate way out-classes Negi. Later Evangeline, however, kicks much butt.
 * Chachamaru uses it facing down a magical wild beast.
 * This is practically King Dedede's Catch Phrase in Kirby: Right Back at Ya!.
 * Then there's that moment in the episode "Sweet and Sour Puss" when a monster called Togeira possesses him, taking away his ability to get angry and causing him to act kind and calm towards others even through all the beatings everyone gives him. Much later, after the King has been pounded and smacked around enough, Togeira, having been storing his anger from within him while everyone was beating on him, stores enough of his anger to unleash it all in one big mega-attack that has Dedede exploding into a massively firey rage that scares everyone and scream at the top of his lungs, "Now it's payback time!" Dedede eventually goes back to his normal self after he slips on a banana peel, therefore knocking Togeira right out of his own head.
 * In One Piece, Luffy angrily battles Zoro because he had slaughtered most of the villagers of an island (early on into the Baroque Works arc), who had given the Straw Hats plenty of food earlier on (pointed out by Luffy looking like an impossibly fat slob at the moment). Luffy was unaware that they were in fact bounty hunters. He even actually utters "Unforgivable" before the battle rages higher.
 * In fact, any time Luffy angrily shouts something about True Companions (at a villain, that is), it means this (as abusing one's True Companions or threatening his own is the one thing that will make Luffy go mad). After this, asskicking ensues.
 * Robin gets like this whenever someone destroys history in front of her (ruins, artifacts, etc.). In the Skypiea arc, the poor bastard who pressed her Berserk Button ended up begging for forgiveness. Robin's response? "No." * CRACK*
 * In the sixth movie, after Luffy thinks he shouts (repeatedly if I remember correctly) YURUSENAI! before proceeding to ... actually, get his butt handed to him for once.
 * This was practically the Catch Phrase of Cure White from Futari wa Pretty Cure. Cue asskicking of the Monster of the Week. Sometimes Cure Black said it at the same time, which is the leading cause of death among Pretty Cure villains.
 * Then, in Suite Pretty Cure, it becomes the pre-Transformation Sequence one-liner Catch Phrase for the lead duo.
 * A favourite line of Digimon Savers's Daimon Masaru.
 * Typically, dubs don't carry this phrase over, substituting it for something that sounds more Badass to the Western ear, but the Savers dub, Digimon Data Squad, actually uses this phrase frequently. And since  is the biggest Complete Monster in the Digi-verse (yes, even Myotismon has met his match) everyone gets a chance to say it more than a few times. The dub of Digimon Tamers, on the other hand, used it once, by Takato and Guilmon as Gallantmon. It was Lampshaded by Beelzemon, who said "You can't forgive me? I don't recall ever asking for forgiveness!" And then the fight was on. It's not Narmful like the Data Squad version because Gallantmon didn't dramatically yell it, but stated it in a more matter-of-fact "this is why I must kill you" manner, befitting a literal Knight in Shining Armor.
 * It's worth noting that despite Digimon being a kids show, Gallantmon was willing to execute Beelzemon, and would have gone through with it were it not for the fact that said enemy's biggest victim, and Juri/Jeri asked for him to be spared.
 * Kouta, from Elfen Lied, is understandably miffed when he realizes that . And the Enfante Terrible Mariko considers her fellow lab project Nana having friends to be cause enough for this.
 * In the finale of G Gundam, Domon says this to, who has been behind all the crap Domon had to go through.

"Prime Minister: "Commander Asuno! If you do this, any hope of compromise will be lost! This war will continue until one side is completely wiped out!" Flit Asuno: "Yes, I know. That was my intention from the beginning.""
 * Gundam AGE follows suit when Flit returns from his battle against  As he's prepared to enter the battlefield one last time, he declares that he will never forgive the UE for
 * This case was an excellent example of how much impact the phrase has lost over the years. When Flit says it, the viewers didn't give it much thought... and then were very surprised to see that, after the Time Skip, Flit meant what he'd said, and had dedicated his life to exterminating the UE, at any cost, regardless of how ruthless he had to be to do it.

"Tao Len: ...You took my friend away and YOU'RE GOING TO PAY!!"
 * This phrase is used a few times in Transformers Super God Masterforce; for example, by Minerva when the Decepticons kill a little girl's puppy, and by Ranger when they seriously injure his horse.
 * The fifth episode of Mobile Suit Gundam 00 Season 2 has the A-Laws
 * When Chrono and Rosette discover Aion's plan in Chrono Crusade (right after ), they fly into a rage and shout "Aion, we will never forgive you!"
 * Subverted in the Fruits Basket manga. Kyo thinks that said this to him  . However, a flashback near the end of the series reveals that what she was trying to say was "If you don't pay your bill, I won't forgive you," an effort to remind him of.
 * When Kagura almost lets slip to Tohru about Kyo's true form, Kyo covers her mouth and says "If you utter another word, I'll never forgive you!". In response, Kagura yanks Kyo's arm behind him and says "Oh you won't forgive me will you?!".
 * Used by The Ingenue Eve Genoard near the end of the Baccano!! light novel Drugs and Dominoes, after she learns that killed her father and brother. She almost shoots him, but is stopped by Luck Gandor, who does the honors in her stead.
 * Priscilla from Claymore. She goes into a CRISIS of "Unforgivable", much like a Shinji's "must not run away", before actually going Berserk. The worst is that it was completely unjustified, and that her immature, self-righteous, ignorant attitude makes her do the heart-wrenching thing that is the basis for all the Claymore plot.
 * Her repetition of "Unforgivable" is more of a Madness Mantra, as it shows her absolute belief in the rules, and marks the beginning of her mental breakdown.
 * Clare from the same manga also utters this, which she mixes with "I will kill you"
 * Like Priscilla above, Fumio of Saitama Chainsaw Shoujo also breaks into a Madness Mantra version of this, just before snapping due to being dumped by her boyfriend. And then we all know what she does next.
 * Used to great effect in Death Note.
 * To illustrate, Light uses a form of this to his girlfriend Misa at one point, when he's telling her not to screw up the task he's giving her.
 * In Azumanga Daioh, Tomo pulls off the "decayed" version of this on Yomi, whose "unforgivable" crime is... successfully using a vending machine after it ate Tomo's money and eating curry without spilling any. Leads to a Crowning Moment of Funny when Tomo chases Yomi around trying to whack her with a cafeteria tray, and hits Yukari instead.
 * In D.Gray-man, someone once managed to get Allen angry enough to say this. EPIC asskicking ensued, but even so he was rather hopelessly outnumbered, and it took to take out all the Mooks.
 * Also, occurs in episode 56 from Allen to Tyki.
 * In Yu Yu Hakusho seasonal Big Bad Sensui forces the heroes to play a video game made real by a pyschic child, who is playing as the game's Big Bad. As long as the heroes keep playing they can't die but if they win the game the kid dies, something Sensui conveniently forgot to tell his child follower. The team is reluctant to does this; but in the end one of them, Kurama, does the deed. Afterwards, Kurama doesn't utter this line but you can definitely tell he's thinking it; both by the expression on his face and his actions later on.
 * Possibly one of the more terrifying examples occurs in the manga adaptation of Breath of Fire IV. Right after seeing an entire village of child-summoners murdered, Ryu utters a This Is Unforgivable! as he unleashes THE KAISER DRAGON (for those unfamiliar with Breath of Fire, think "nigh-unstoppable Kaiju-esque Dragon Of Mass Destruction"). It takes a Cooldown Hug from Nina (whom, for the first time in her life, is scared out of her wits by a dragon)--and this is after the Kaiser Dragon has not only decimated an entire LEGION but literally bored a hole through a mountain via its Breath Weapon.
 * Tatewaki Kunō says this ('Yurusen!' actually) in Ranma ½ during his first fight with Ranma, after he insults Akane. Cue ass-kicking - Kunō's, of course.
 * Peach Girl: Momo says this when a trio of girls who are in love with Kairi destroy a necklace Toji gave her because they are jealous of her for getting Kairi's attention.
 * In Soul Eater, Death the Kid is as likely to use this in reference to anyone affecting his beloved symmetry as he is to any villain who likes to gather human souls for themselves and/or insult Shinigami-sama.
 * Tsuna says this when he is enraged by Byakuran . There is a good reason why that chapter was labled "The Last Blow."
 * And again in chapter 339 to Daemon Spade.
 * In chapter 51 of Mirai Nikki this is written on Yuno's diary.
 * In the 7th OVA of Hellsing Seras screams this repeatedly at Zorin when the latter insults the dead Pip, calling him an 'insect'. And then she goes utterly ballistic.
 * Any time this is uttered in Higurashi no Naku Koro ni (or "I'm sorry," if it's said sotto voce), someone is going to get murdered. If they're lucky.
 * Higurashi Kira Episode 2 had Satoko declaring that she would not forgive Tokyo Magika for hurting her Nii-nii. Later, Oyashiro Rika and Trap Satoko declared payback time before moving on to finish off Nail Ripper and send Takano flying.
 * In episode 5 of Gankutsuou Maximilien screams this during his fight with Albert.
 * Ashley of Uragiri wa Boku no Namae wo Shitteiru yells this in episode 12 because Hotsuma ruined her clothes during their fight.
 * Maria of Umineko no Naku Koro ni yells this repeatedly in episode 22 before taking revenge on her abusive mother.
 * Earlier, Battler was angered by Beatrice having gleefully laughed about, so much so that he decided he wouldn't accept "that bitch" as his opponent. He told Virgilia that she could call her student if she wanted to, but that didn't mean he would forgive her. A disappointed Virgilia told Beato to try being more encouraging if she was to be forgiven by him and accepted as his opponent.
 * In the first season of Mermaid Melody Pichi Pichi Pitch, the heroines say this most of (if not all) the time to their enemies (be it the Dark Lovers or the Black Beauty Sisters) for whatever it is that they did that terrorized the seas or the people, be it making a theme park only to destroy it, chase down a boy who assaulted them with a water hose and retaliate by attacking, or even planning to force-feed chocolates to girls (which would turn the Mermaid Princesses to mermaid form).
 * In Shaman King, after Hao eats his brother Yoh's spirit (after which he attempts to digest it and therefore cause him to become one with him), Yoh's friends fly into a rage and make several futile attempts to attack him out of unforgiveness towards him. Even his fiance' Anna calls Hao a Complete Monster and says that she will never forgive him. Things settle down a lot when Manta helps them defeat his Shikigamis, though, and even more so when Yoh regains his spirit to the relief of all of his friends, and even Anna welcomes him back.

"Darunia: Link, you must not let your emotions erupt when you face Ganondorf. If you do, you will never be able to defeat him. Link: You're right, Darunia. But... I will never forgive Ganondorf."
 * The manga adaptions of the Zelda series done by Akira Himekawa seem to love this Trope. For example, in the The Legend of Zelda a Link To T He Past manga, after Agahnim sacrifices Zelda in front of Link and sends her to the Dark World imprisoned inside a crystal, Link shouts out, "Agahnim, I'll never forgive you!" before absorbing his magic with the Master Sword, leaving Agahnim shocked in a "This Cannot Be!" manner and sending the magic right back at him.
 * Also, in the The Legend of Zelda Ocarina of Time manga, after Link is forced to kill his old friend, Volvagia, in order to free him from Ganondorf's control and awaken Darunia as the Sage of Fire, he calmly declares this trope to the Big Bad himself.

"Mokou: KAGUYAAA!! Today I'm definitely NOT going to forgive you!! Kaguya: Oh no... What am I going to do if you don't forgive me~?"
 * In Fullmetal Alchemist, Winry finds out that  is responsible for the murder of her parents,
 * Fujiwara no Mokou in the Touhou manga Inaba of the Moon and Inaba of the Earth likes using this trope when it comes to her bitter rival Kaguya. Face it, she just hates her so much because of the humiliation she gave her father.

"Duke: That was for the team... [punches and sends COBRA Commander sliding on his feet towards the edge] ...and THAT was for YOUR PAYBACK!"
 * Villain example: Rosine, the Big Bad of Berserk's Lost Children arc, uses this line on Guts after he, which has the effect of supremely pissing Rosine off—badly enough in fact, that she decides to.
 * Another villain example from Berserk: when Nosferatu Zodd's duel with Guts is interrupted, he roars this at the interlopers. This guy takes the Worthy Opponent Blood Knight dynamic really seriously.
 * An actual (anti) heroic example comes from Guts in volume 17, where he says something to the same effect. After getting a What the Hell, Hero? lecture handed to him, Guts rethinks how he dealt with avenging the Hawks  and that since he technically played a role in the group's downfall, he didn't have a right to avenge them... however, for what Griffith did to Casca during the Eclipse , Guts said that he would never forgive Griffith.
 * Even the otherwise lighthearted Tengen Toppa Gurren Lagann has an example: post-Time Skip, Yoko, hiding her real identity. When two rogue Ganmen show up and start wrecking the place, she gets angry. But when they threaten the life of one of her (a little girl), she utters the line as she goes batshit fucking mad and breaks out the hidden armory. Asskicking ensues.
 * In Episode 13 of G.I. Joe: Sigma 6, after having heavily damaged his ability to assume battle mode by blowing up his Power Stone in front of him, Duke battles it out with COBRA Commander in a one-on-one duel without weapons to have him prove how tough he is. After taking a few blows from the villain, he shouts out, "I've had it with you!" before fighting back and besting him with some more punches.

"Ichigo: You're a wicked monster and you've terrorized this city for the last time. Now you'll pay!"
 * from Durarara!! mumbles this during a flashback of middle school.
 * In Mai-Otome, while Arika fights Tomoe, she reveals that she was responsible for all of the things Miya took the heat and got expelled for. Arika only responds with shock until Tomoe, while mentioning her responsibility in the acid drop that injured Arika's friend Erstin,, prompting Arika to respond with this phrase.
 * Tokyo Mew Mew does this really well, with the Mew Mews using this against the aliens and their Chimera at random times, either before or after transforming.
 * Ichigo/Zoey even uses this trope as quite a Badass Boast towards a monster attacking Tokyo in her dream in the beginning of an early episode.


 * Rosario Plus Vampire: In chapter 41 of the second manga season Kurumu says "...won't forgive. I won't forgive you if you hurt Tsukune!"
 * In chapter 50 Tsukune says this to Miyabi because he invaded Mizore's village and planted a Forceful Kiss on her.
 * Although the intentions aren't carried over between meetings, this is often Hayate of Hayate the Combat Butler's manner when Nagi is threatened. Gilbert is frequently the target, and clearly frightened of the consequences of his actions, though not repentant not to try again at a later date.
 * Played for Laughs during an episode of Beelzebub. After a demon world plant eats the...thing he brought to life from a demon world book, Beel goes all fiery mad, and in his baby gibberish declares "I will never forgive you for this!"...and gets swatted aside. He is just a baby after all.
 * In Episode 9 of Sonic X: How dare you, Eggman! You destroyed Amy's lucky bracelet that she made for Sonic to protect him when he goes in the water, despite his fear of it. And she reacted with the line of "I don't believe it!" Not only did it make her cry a few seconds afterwards, but shortly after, she flew into a rage with fire burning in her pupils. You hit Amy's Berserk Button and you didn't even know it. Now she's REALLY PISSED at you, screaming at the top of her lungs, "Now you're gonna PAY!!!", which takes you by surprise. Once she charges at you and one of three of your current Robots Of The Week, Serpenter, shouting to you both "Don't mess with me!" along the way, and proceeds to kick its ass before going after you next, that's where you realize that you never should have made her this pissed off at you and that you're completely and totally screwed. Cue Oh Crap.
 * Also, in the original edit, this is Sonic's final line at the end of the finale of Season 3, obviously declared against Eggman. It was replaced in the dub by another line in the form of "Life never stays slow for long! Thank goodness! Watch out, Eggman, I'm comin' at ya full speed!"
 * In Steel Angel Kurumi 2 Kurumi says this whenever Nako gets hurt.
 * Hanaukyo Maid Tai La Verite episode 9. After Lemon, Marron, and Melon speak rudely to Captain Konoe Tsurugi, Konoe's lieutenant Yashima Sanae tells them "Speaking so rudely to captain...unforgivable!" She then chases them away.
 * A rather odd example occurs in A Certain Magical Index when Touma says this to the villain of the current arc, Oriana Thompson, who is involved in a plot to brainwash the city. It's not the possibility of mass mind control that really upsets him, though, it's that her actions are interfering with the festival that's going on. Yeah, Touma can be a bit strange.
 * In Sukeban Deka, "Saki's" catchphrase is "Omaera, Yurusansezore!" (You Won't Be Forgiven!)
 * Every member of Fairy Tail will make sure that anyone who would disrespect their guild or hurt their friends will get no less than what they deserve.
 * In an episode of Ouran High School Host Club Tamaki says "Unforgivable!" when eavesdropping on a moment between Harushi and Hikaru.
 * Cowboy Bebop episode 22 "Cowboy Funk". During their confrontation on top of the ruined building Spike says "I will never forgive you" to Cowboy Andy, who's been interfering with his efforts to capture Teddy Bomber throughout the episode.
 * In Peter Pan No Bouken Hook says this to a giant sea creature (no, not the crocodile), which might make uninitiated anime fans watching the subbed version wonder why a giant sea creature cares whether Hook forgives it or not.
 * Black Cat: In the anime Train says this after Creed kills Saya.
 * FLCL. In episode "Brittle Bullet" Naota's father walks into Naota's room and catches him and Haruko accidentally kissing. He is interested in Haruko himself, so he tells Naota that he can't forgive him and challenges him to a duel for Haruko's affections.

Film
"Orin: What I ever do to you? Seymour: Nothing. It's what you did to [Audrey]."
 * Little Shop of Horrors:

""Arthur Burns is a monster. An abomination. You were right to break company with him; what happened at the Hopkins place was unforgivable."
 * Alluded to in the film Gung Ho, when a shouting match between an American and his Japanese boss gets physical after the American says, "Oh yeah? Well, if you guys are so great, how come you lost the Big One?"
 * A western equivalent appears in Star Trek III the Search For Spock where Kirk repeatedly kicks Klingon General Kruge, screaming "I! HAVE HAD! ENOUGH! OF YOU!" and then kicks Kruge down a cliff.
 * Also Picard's rant about the Borg in Star Trek: First Contact. "[We have fallen back] This far, and no further! The line must be drawn here!"
 * The Proposition.

"Born in grief Raised in hate Helpless to defy his fate Let him run Let him live But do not forget what we cannot forgive"
 * In the Chinese action film "Flash Point", the main character and detective Mah Jun, played by Donnie Yen, chases after a criminal on foot in the streets of Hong Kong. The criminal runs into a restaurant, grabs a young girl as hostage and holds her upside down by the legs. When Mah Jun catches up to him and holds him at gun point, the crook threatens to drop the girl on her head if Mah Jun doesn't drop his gun. Mah Jun complies but the criminal throws the girl forcefully aside anyway right outside the restaurant unto concrete ground injuring the girl. Mah Jun has a very brief Heroic BSOD and his face clearly shows a This Is Unforgivable! expression followed by giving the attacking criminal a suplex from hell and then pummeling the man to to death.
 * Yes, even some Disney movies have these. In Mulan II, Mushu, pressured by Cri-Kee, admits to Mulan what he had done. Mulan is enlightened by Mushu's admittance, but also gets mad at him. She even says that what he did was unforgivable, and when he tries to ask to help some more, she replies with "You've helped enough."
 * In The Lion King, Simba says a line that comes close enough to this to Scar: "You don't deserve to live."
 * Not to mention, some of the lyrics to The Lion King II: Simba's Pride song "One of Us" contain a variation of this.


 * Worth noting this was due to a misunderstanding - Kovu had been raised as a Tyke Bomb, but had already pulled a Heel Face Turn by the time what he was convicted of occured; Simba misinterpreted the situation and refused to listen to otherwise, until the ending where his eyes were opened. It's worth noting that the very theme of The Lion King II: Simba's Pride was Forgiveness.

Literature
": You can't... you can't just forgive me. Mace Windu: As a member of the Council -- you're right. I can't. As your Master, I won't. As your friend -- as your friend,, I can forgive everything. I already have."
 * Michael, a Badass Abnormal, good Christian paladin type in The Dresden Files forgives and gives another chance to anyone and anything, even the odd Eldritch Abomination here and there. But, in the short story "The Warrior," when one of his daughters gets bruised by a Well-Intentioned Extremist priest, all bets are off.
 * Uh, there was a LITTLE bit more than bruising involved. The Well-Intentioned Extremist had also kidnapped the girl (knocking her unconscious in the process), tied her up in det-cord (explosive-stuffed rubber tubing) and rigged her with an electronic detonator. He then insisted that a Walking Techbane wizard, whose very presence could have caused a malfunction in the detonator and set off the cord, be the one to release the girl. Michael had every RIGHT to be in full Fist of God mode.
 * Invoked and subverted in Shatterpoint:


 * In Dune, the depredations on the Zensunni people in the distant past are remembered in the oral tradition of their descendants, the Fremen, with the Badass Creed "Never to forgive, never to forget!"
 * In A Song of Ice and Fire, when  Tyrion says "I have never like you,   so I never did you harm. You've ended that. I will hurt you for this. I don't know how yet, but give me time. A day will come when you think yourself safe and happy, and suddenly your joy will turn to ashes in your mouth, and you'll know the debt is paid." He may not say the words, but this Badass Boast embodies the spirit of this trope very well.
 * Likewise, he doesn't say the words, but Tyrion's reaction to the lies and betrayal by  is similar to this.
 * Actually quite a few characters react this way to being betrayed. Which happens quite a lot.

Live Action TV
"Lee: We have to break rules, we have to bend laws, we have to improvise! But not this time, no, not this time, not for Gaius Baltar."
 * On Buffy the Vampire Slayer, Faith actually tries to get Willow to give her the whole "you can still be a good guy" speech, instead getting Willow telling her she's way past forgiveness. At least part of this is, of course, because she had kidnapped and tied up Willow though. Ironically, Willow becomes one of the few people who actually could later understand what Faith was going through, having gone evil and killed someone only to be brought back by someone showing caring and kindness when she didn't deserve it.
 * Still a Crowning Moment of Awesome for Willow, who is all alone in the mayor's office with Faith who has already gone rogue and is threatening Willow with a huge knife.
 * The climax of any Toku show involves saying this phrase, followed immediately by a showdown with the Monster of the Week.
 * The Babylon 5 episode "No Surrender, No Retreat" opens with Captain Sheridan defiantly declaring "Enough is enough!", after President Clark's forces attack yet another civilian target. He's not even remotely kidding.
 * "I want you all to understand this! If you do this, there will be no forgiveness. No amnesty. This boy died honoring his uniform. You, you'll die with nothing."
 * President Laura Roslin's speech in the following episode is arguably an even better example: "No. Not now. Not ever. Do you hear me? I will use every cannon, every bomb, every bullet, every weapon I have down to my own eyeteeth to end you. I swear it! I'M COMING FOR ALL OF YOU!"
 * This was deconstructed when Lee testified at Baltar's war crimes trial - Lee pointed out all the things members of the fleet had done that should have resulted in imprisonment (or execution) that had been "forgiven" by either Admiral Adama or the President, and that the only reason Baltar's crimes were unforgivable and deserved his execution was that no one liked him.

"Rita [to the rangers]: You'll pay for THIS!!"
 * An episode of Alias contains the following emotional speech. It doesn't lead to a physical fight (though these two characters do fight earlier in the episode) but it sets the tone for a temporarily broken relationship.
 * "What it comes down to is faith. What I was hoping you would say is, ', I gave up, I gave up. I lost faith.' But what you came here for was closure. And there is not a chance you're getting that from me. I'm not gonna say 'I understand.' I'm not gonna sympathize with you and tell you how hard it must be for you... But you want to know how I am? I am horrible, . I am ripped apart. And not because I lost you, but because... if it had been me... I would have waited. I would have found out the truth. I wouldn't have given up on you. And now I realize... what an absolute waste that would have been."
 * Said word-for-word by Derek in Grey's Anatomy about Meredith sleeping with their vet... after they broke up almost a year ago because he was married and hadn't told her. He was still with his wife at the time. Of course, she's quick to point out that "I never asked you to forgive me" and "I make no apologies."
 * "By the time you all get back from break...you won't recognize this school at all."
 * Rita of Mighty Morphin Power Rangers sometimes says this to the rangers whenever they ruin her plans and destroy her monsters.

"Grizzaka: You've destroyed all of my warriors, my royal guards, and the great overlord Carnisoar. Finally, I shall destroy you!"
 * Another villain example: Grizzaka to the rangers in Power Rangers Jungle Fury during their huge fight:


 * How I Met Your Mother had a version of this when Ted found out that Barney slept with Ted's ex-girlfriend Robin in a blatant violation of the Bro Code. Barney expects Ted to be angry but forgive him since Ted is very easy going and a bit of a pushover. Instead Ted is so furious at the betrayal that he punches Barney in the groin and wants nothing to do with Barney from that moment on.
 * In an episode of Merlin, Uther is blaming Morgana for her betrayal against the kingdom for trying to help the young druid Mordred escape. Morgana, who does not wish for Mordred to be executed, says that she will never forgive him if Mordred dies. Of course, Uther, on the other hand, states that he wasn't asking for forgiveness.
 * And when Merlin tries to prevent Mordred from escaping the Camelot Knights, Mordred kills them and warns him telepathically that he will never forgive him nor forget his betrayal towards him.
 * This was practically Kotaro Minami's catchphrase in Kamen Rider Black.
 * In The Borgias, Rodrigo is telling his sons how to juggle the various bribes that will get him elected Pope. When one of them points out that his tactics are not exactly "holy", Rodrigo replies "God will forgive us, my son. But I will not. Forgive. Failure. From you, or your brother." Quite what he was threatening them with (if anything, since he does genuinely love his children,) is unknown, but since the line is spoken with all the verbal badassery Jeremy Irons can muster, it's understandably taken very seriously.

Video Games
"Cyan: This is unpardonable..."
 * This is Lenneth Valkyrie's big proclamation in Valkyrie Profile. She had been impassive up to now.
 * Vyers from Disgaea uses these exact words, twice, when Laharl, his would-be rival, unflatteringly refers to him as irrelevant and redubs him "Mid-Boss". He loses the ensuing battle, and the insulting moniker sticks with him for the rest of the game.
 * Kim Kaphwan from the Fatal Fury and the King of Fighters games has a variation of this. Whenever he fights a criminal (or simply evil, or perceived as evil) opponent, he points his finger at them and says "Aku wa yurusan!" ("Evil cannot be forgiven!"). Starting with the NESTS saga (King of Fighters 1999-2002), he even complements the pointing with Glowing Eyes of Doom.
 * His disciple May-Lee actually does something similar in King of Fighters 2001, Kamen Rider-ish pose and all.
 * Declared by Tails after in Sonic Adventure 2. He seems to largely forget about it when things settle down, though.
 * Used by Mickey in Kingdom Hearts II after Goofy has been (apparently) killed, triggering his costume change along the way and making room for what may be the most epic battle sequences in this game.
 * Just the fact that Mickey (THE Mickey) says "They'll pay for this," is enough to put chills in your spine.
 * The original Suikoden lets you pull this at least twice with already-defeated foes. In one case, this is actually the wrong response, as the "villain" was actually Brainwashed and Crazy, and is one of the 108 Stars of Destiny. In the other case, it's perfectly fine to take this option, as the character is legitimately a self-serving sleazeball who caused the death of the lead character's best friend out of nothing more than petty greed—the conversation option for killing him actually reads "You're the one person I can't forgive."
 * Another moment is after Gremio, your protagonist's servant and protector, fools checkpoint guards into thinking that said protagonist is not the now-rebellious son of Teo McDohl, but his own son, and begins to shout at him for never doing anything right, even now being mistaken for a criminal. He is then stopped by pleading guards from killing his 'son' right in front of them. After safe passage, Gremio apologizes to the protagonist for his improvised actings, to which you can actually respond to with "Unforgivable!" This can go on for a short while, and messing with him is all fun and laughs until it nearly results in him killing himself out of shame. Yikes.
 * Subverted in Devil May Cry 4, wherein Credo utters this to Sanctus, who blatantly used Credo's sister as bait in his plans and thus the one thing that shook Credo's loyalty to the Order. The kicker?.
 * In the Japanese version of Final Fantasy VI, after Cyan realizes that the Empire has poisoned Doma's water supply, he races around to find survivors, and when he races into his own room, he finds his wife and son dead. He screams at the Empire at the top of his lungs and races off to kill as many Imperial soldiers as he can, but not before muttering in shock.

"Sephiroth: Fighting me won't help you recover the Crystals. WoL: I suppose. Sephiroth: Well then... Why come before me? WoL: You hurt my ally. Sephiroth: "I won't forgive you"... you might say?"
 * Ruined by the otherwise okay Woolsey localization, which has Cyan yelling something like "THIS CAN'T BE HAPPENING! IMPOSSIBLE! IDIOTIC!"
 * Bonus points: The song played during the scene afterward, where Cyan is on his blind Roaring Rampage of Revenge? It's called The Unforgiven.
 * Olaf of Advance Wars 2 reacts this way upon seeing his Hometown ravaged and toyed with by Lash.
 * In one of Silent Hill 2's endings, yells "Do you really think I could ever forgive you for what you did?" before transforming into the game's end boss.
 * Played straight several times in Dissidia Final Fantasy, but lampshaded when the Warrior of Light confronts Sephiroth.

"Sion: This is... This is unforgivable, Dauragon!"
 * Final Fantasy Tactics: Ramza, a purer than pure hero who only draws his sword once during a cutscene, who tries to talk every enemy he meets out of fighting, who is basically as forgiving as JESUS finally finds three people in all of Ivalice even he will not forgive:
 * Shouted by Sion Barzahd before one of the final battles in The Bouncer.

"Alucard: Demon. Death is too good for you."
 * When Teen Gohan transforms into Super Saiyan 2 form in Dragonball Z Budokai 3, he screams "I won't forgive you!" If you don't know why, check Dragonball's entry under the Anime section above.
 * In Castlevania: Symphony of the Night, Alucard confronts a succubus who has been imitating his dead mother just to mess with his head, and conveys his intentions rather stoically before an inevitable boss fight:

"Edgeworth: ...Nnngh... That killer is going to pay! This tea set...! Gumshoe: Yikes! You're really mad over this! Edgeworth: This tea set is very dear to my heart and can only be bought in England. It cost more than your whole month's paycheck. Gumshoe: W...Whaaaaaaaat!? Now I feel like the killer's wasted one of my monthly paychecks!"
 * He does say "Yurusan" in the Japanese, and is so VERY damn stone-cold about both that and the worse-than-death fate that his killing her in the dream-world will bring about (it's a death of the soul, so her spirit will never find rest and will wander lost for eternity). This followed by the only fade-to-black death in the game, and (in the original Japanese; the dub is uh...different) a very creepy cut-off scream from her.
 * And the sad thing is, you just know that he was a lot nicer than Dracula would have been if he found out about those shenanigans. 'Don't mention Lisa' is a good rule to follow.
 * Ishida Mitsunari from Sengoku Basara, whose vocabulary seems to be largely limited to screaming either this or the name of his rival Ieyasu at the top of his lungs. He even takes it one step further by refusing to forgive not only Ieyasu, but the whole world.
 * In the Ace Attorney series, there are two things Phoenix Wright considers completely "inexcusable", as he says in case 3-3: Poisoning, and betrayal. There's a deep, personal reason for this.
 * Used for humor in the first case of Ace Attorney Investigations. A body is found in Edgeworth's office, what gets him really mad? Someone broke his prized tea set!

"Edgeworth: Some time in the near future, one very betrayed assassin may appear before you. Needless to say, that man is very good at what he does. I'm sure you know what I mean, if you watch this video."
 * And let's not forget Shelly de Killer. After finding out that his client taped the crime scene for blackmail, he The moral of the story: Don't piss off an assassin.

"Phoenix: (Unforgivable, Von Karma. Suppressing evidence like this... You're as bad as your father!)"
 * Phoenix also views Franziska's suppressing a photograph during Maya's trial this way. It turns out there's more to this tactic than he thinks, but she is still trying to get Maya convicted by any means necessary.

"Lyn: Unforgivable! This is... a foul deed. Beyond foul."
 * Surprisingly often used in Fire Emblem. For example, Renault versus Nergal in FE7: "!" Or Jill versus Ashnard in FE9: "" Or Elincia versus Ashnard: "" Yep, FE loves this declaration.
 * In the seventh game, adorable assassin-in-training Nino is given the chance to confront
 * Lyn in FE7 has two of these. The first is against her granduncle, Lord Lundgren, for trying to assasinate her, poisoning her grandfather (his own brother), and harming the people under his charge to whom he has a duty. The second is an actual utterance, when she, Eliwood and Hector discover :

"X: So you're the Big Cheese? Ride Boarski: Big Cheese?! Arggghhhhmm! How dare you call me that! I'm the Head Honcho, for crying out loud! X: OK, whatever you say. I order you to disband this motorcycle gang! Ride Boarski: Motorcycle gang?! Why you!! You've gone too far! I'll make you pay for this, with a duel!"
 * In his own story path, Hector shares in the above (for Lyn's second This Is Unforgivable!) by swearing a vendetta against the Black Fang until he finds the one responsible. He also echoes Lyn's "I have neither pity nor mercy for you" when he confronts Nergal. Notably, Eliwood does not possess this quality
 * When X declares to Gate in Mega Man X 6, "Time to teach you a lesson, Gate! You used Zero's DNA to cause the Reploids pain. All for your own ego! I won't forgive you!"
 * Also, for a villain example in said franchise:

"Grolla: Michael Zeppelin... your reasons mean nothing to me. There will be no mercy. You shall pay for this with your life."
 * Rosenkreuzstilette also enjoys using this trope as well. For example, after laying her undead grandfather Raimund Seyfarth back to rest in her alternate mode, Grolla, both infuriated and deeply hurt, declares this trope in vowing to punish Graf Michael Sepperin for disrupting his peaceful slumber. And, of course, this is not the only "This Is Unforgivable!" moment in the game.

"Zorne: About time you showed up, Grolla! If it weren't for you, Trau would still be a part of RKS! You're gonna pay for that!"
 * Also, in the main game, Spiritia and Lilli say two variations of this trope to
 * Zorne is also quite fond of using this trope, especially as one of her pre-battle quotes or when Grolla confronts her after having defeated her friend Trauare, which, of course, is one of quite a few things that can press Zorne's Berserk Button.

"Ragna: I'll never forgive you, you son of a bitch. I was gonna tell you to die a slow, painful death, but I don't got the patience to wait around, so you're dying now."
 * Guilty Gear uses some "This Is Unforgivable!" moments as well. For example, May says this to I-No when she catches her tormenting and hurting her friend Dizzy.
 * BlazBlue is another game that also likes this trope. For example, Ragna the Bloodedge, the main protagonist, says this when he uses Hell's Fang on his hated rival Jin Kisaragi. The same thing is also done in his winquote against him.

"Kokonoe: I've just got one question to ask you. Why did you betray my mother? Hazama: "Betray?" Come on, don't give me that. It's not like the Six Heroes were buddies... then the other day, I told the old man, "We're buddies, right?!" Hahahaha! Kokonoe: You... you bastard! I'll never forgive you! Lambda! Kick the shit out of him!"
 * Also, in Continuum Shift, Kokonoe declares this to Hazama when he fights Lambda-11 in his arcade mode run.

"Ragna: Terumi... Terumi... I will never forgive you! Hazama: You won't forgive me? Like I give a damn! Just shut up and die already!"
 * And for the encore there's this exchange between Ragna and Hazama/Yuuki Terumi in Continuum Shift's True Ending:

"Reimu: Talk is cheap! Making such a huge pitfall trap is unforgivable!"
 * On a related note, since Hazama/Yuuki Terumi is.
 * Reimu Hakurei of Touhou uses these words when Sanae Kochiya fights her in her story run in Touhou Hisoutensoku because she accuses her of making a huge pitfall trap for her to fall into:

"Yukari: Ah, I wonder if the air was too heavy for a vampire. Sakuya: Yakumo Yukari... you! Yukari: Hahaha...don't let yourself boil over yet. There's more to come. Sakuya: I can't...I'll never forgive you for this!"
 * As does Ninja Maid Sakuya Izayoi in Koumajou Densetsu II during the final battles upon learning that Yukari was behind everything that happened with her mistress:

"Great Godfather of Soul: Have you come back to rub your victory in my face, hero? Someday, with Chaos Lord Discordia's help, I'll make you pay for taking my title from me! You can count on that!"
 * In Adventure Quest Worlds, the hero helps the Great Godfather of Soul send a Royal Jar of Honey to Lord Ovthedance as a peace-offering in order to help him get the magical shoes the Horc used to cheat him out of victory in dance contests. Of course, what the hero doesn't know is that the Godfather was setting up Lord Ovthedance by claiming he cheats in dance contests. After beating him and realizing that his shoes aren't enchanted (the Lord didn't need enchanted shoes to win anyway), the hero realizes that the Godfather lied and used him/her, apologizes to the Lord for seeing to it that he's in no shape to dance at that point, and decides to show the Godfather who's boss. After receiving dancing lessons from Lord Ovthedance, he/she challenges the Godfather to a /Dance-Off competition, and wins the /Dance /Dance Minigame, taking the title of Dancing Champion. The Godfather isn't too happy about that, and that's when, while he declares this trope to the hero, Chaos Lord Discordia is mentioned for the first time ever by him.

"One-Armed Bandit: My gang is all over this area. You'll never make it to that ship! [to Voltaire] You with the guitar... This is all YOUR fault. I'll get you for this!"
 * In the Golden Ruins area of the Frostval events, the hero and Blizzy confront Maximilian Lionfang, who has kidnapped the Spirit of Frostval and stolen the presents from the town of Frostvale. Believing that the world must suffer for bending its will to evil and that there can be no peace until all evil is completely and permanently vanquished, Lionfang burns the presents with his whip as a demonstration of one of the "prices that Lore must pay for the pathetic truce between Good and Evil." A horrified Blizzy lets out a Big No, Lionfang gives off an Evil Laugh, and, of course, the hero doesn't take that too well. He/she shouts to him, "You'll pay for that!" before proceeding to hand his butt to him on a plate for the second time and afterwards tell him, "Keep the change, you filthy animal," which is also a memorable line from Home Alone.
 * In the 2011 Friday the 13th event:

"Hero: DRAKATH! I know you have a hand in this. When I find your new minion, I will make them PAY! And I need to know who! ...I'm not sure where to start, but I think I have an idea."
 * He said that to Voltaire because he blamed him for his involvement in the hero defeating him, and wanted revenge on him for it. He would later keep true to his desire for revenge against him by ambushing him during their confrontation with Lord Krom Wrath, and dragged him somewhere where they could settle their score while Deady in his One-Winged Angel form of Urkor Malravenus fought Krom Wrath and the hero used the Vorutanian Key Blade to beat Yahorneth, save the world from being taken over by the Necrus and Krom Wrath, and force the Necrus to retreat back to Necronus. It later turned out that Voltaire survived his fight with the One-Armed Bandit and in the process of doing so got his mechanical claw in place of one of his hands.
 * In Doomwood Part 2, Gravelyn calls out Noxus.
 * In the Bloodtusk saga, after sending the Horcs and Trolls back home to rest up from all the fighting they did after defeating the alliance soldiers led by Cynari and Tibias, the hero makes a declaration that, when he/she finds the Chaos Lord running the madness taking place in Bloodtusk Ravine, he/she will make them pay, especially for murdering Antiphuus. He/she also gets an idea on where to start looking for information on the Chaos Lord.


 * Later, in the same saga,.
 * Shouted by the protagonist of Tokimeki Memorial 2, when his childhood friend Hikari is his battle partner and has activated her Taking the Bullet Limit Break to save him from the enemy's Limit Break. He then enters in an Unstoppable Rage that dramatically ups his Attack Power.
 * In the seventh dungeon of Paper Mario, the Crystal Palace, one of the puzzles to solve involves Bombette and five Duplighosts disguised as her. This puzzle is quite simple to solve, really - all Mario has to do is hammer all five of the Duplighosts disguised as her. As a matter of fact, Mario can tell who the real Bombette is because she's the one who says that she will never forgive him if he messes up.
 * In One Piece Unlimited Adventure, when Robin says before the fight with Eneru that she'd rather not see him again (in canon, he nearly killed her and almost destroyed Sky Island), an audio clip of her saying "Unforgivable!" is heard. When Shanks uses his ultimate attack, he yells "I won't forgive those who hurt their friends!" (a mistake in pronouns, as it's a reference to his being willing to tolerate insults, but not those who threaten his friends)
 * In the ending of Pokemon XD: Gale of Darkness, Ardos tells Michael he can't be forgiven for foiling Cipher's plans so utterly.
 * Cheren drops an "I'll never forgive them for this!" regarding Team Plasma in Pokémon Black and White.
 * In Deus Ex, after you  says in a voice full of hate "No, I cannot forgive. No... not the killing of  I will follow you. Denton; I will get you!

Web Original
"Nostalgia Critic: To err is human... TO MAKE THE WORST PIECE OF COW SHIT TO EVER STAR A BAD-ACTING, 7-FOOT TALL BASKETBALL SUPERSTAR IS UNFORGIVABLE!!!"
 * In the first video (and most popular) of the Unforgivable series, this trope is averted really, really hard. The narrator essentially meets a woman while he is plotting to buy pants with stolen money, gets her number, and takes her out on a date. This date consists of her buying him food, him treating her rudely, and eventually . He then shouts, "UNFORGIVABLE!" at the end. However, after watching the rest of the video, this only proves that he is an extremely angry person who gets upset about minor things.
 * At the beginning of The Nostalgia Critic's pre-recorded review of Kazaam:


 * In Tasakeru, Zero says this  As he's a former Samurai, the usage is deliberate.
 * In Dungeon Keeper Ami, what amounts to this happens during the invasion of Dreadfog Island, when

Western Animation

 * Western animation equivalent: Bugs Bunny's declaration, "Of course you realize, This Means War!" heard (as per Chuck Jones) when the happy-go-lucky wabbit is finally pushed to the wall. Cue asskicking, etc. Of course, Groucho Marx said it first.
 * This line is also uttered by a character in a Woody Woodpecker short.
 * And then, of course, there's the Animaniacs version: "Of course you realize, this means -- Warners!"
 * Unfortunately, when Jack-in-the-Box humourously quotes this statement, it's misinterpreted to disturbing effect in a possible future.
 * In the Winx Club episode "Virtual Reality Check", after witnessing her pet rabbit Kiko seemingly fall into the lava below while chanting "Say this once, say this twice, cast the spell and all will be well" twice after the Trix destroy the platform that he is trapped on, Bloom flies into a rage and shouts "I'm going to get you for that!" while powering up her Dragon Fire power before unleashing the full extent of its wrath on the witches. This caused her to pass out, but the spell did work...even though it had a little too much of an effect and multiplied Kiko a lot. (Luckily for Bloom, she could tell that the real Kiko was the only one sleeping.)
 * Transformers Animated: "Wasp... forgive... Bumblebot...
 * In The Spectacular Spider-Man, Black Cat says that she'll never forgive Spider-Man for turning her father into The Atoner after he, so that he refused to . Admittedly, there's a chance she might have, but the show was Too Good to Last so fans were Left Hanging on the subject.
 * Many Popeye cartoons find the sailor, pushed to the limit, saying, "That's all I can stands, I can't stands no more!!!!"
 * In Avengers Earths Mightiest Heroes, Hawkeye's "You're dead to me!" is a particularly harsh variation reserved for a former friend, Black Widow.
 * In Teenage Mutant Ninja Turtles 2003, Raph gets so angry over having been paralyzed by one of the hornets earlier in the "April's Artifact" episode that he declares, "Bugs... must... PAY!"
 * Later, in "Same as It Never Was", Donny becomes enraged at Future Shredder after the Karai Legions kill Future Mikey to such horror from Don that he lets out a Big No, plowing his way through the androids declaring that Future Shredder will pay for it, just before blasting away at Future Shredder with his exo-suit.
 * Also, in the same episode, after Future Karai kills Future Leo from the back, an enraged Future Raph, after letting out another Big No, clearly tries to kill Future Karai for it. He gets killed by her, of course... only for Future April to avenge them both by blasting Future Karai hard enough to kill her.
