Pre-Ass-Kicking One-Liner/Anime and Manga

"Touma: I will break it... That illusion of yours!"
 * Done by Luciano Bradley in Code Geass. "Question! What is it that you value the most?" (cuts to a look of absolute fear from the victim) "That's right. YOUR LIFE!"
 * Tossed right back at him by Kallen Stadtfeld, before she gives him the payback he so richly deserves.
 * "Tag. You're dead."
 * Vegeta from Dragon Ball Z has a ridiculous amount of these. "Does a machine such as yourself experience fear?!"
 * "Maybe if this were five-hundred times Earth's gravity, you would have the advantage. But ten? I don't even feel it."
 * Additionally, does it experience nocturnal emission?
 * Gohan also delivers an immensely badass one to Super Buu when he arrives on the battlefield after . Buu says to him "So hotshot, you want to fight Majin Buu?" and Gohan responds with "Fight you? No, I want to kill you," and then lays the biggest beating on Buu that he had probably ever experienced.
 * The Prince of Tennis: Ryoma's "Mada mada dane" ("You still have lots more to work on") before turning around and wiping the court with an opponent he was losing against up until that moment.
 * Another Ryoma, though from Getter Robo. He purposefully grabs hold of a yakuza boss' knife blade and tells him "What's the matter? Come on, either push or pull. You'll save face if you at least chop off one finger" before kicking his terrified ass and scaring off the rest of his thugs.
 * You really don't want to be around when Sesshoumaru of Inuyasha fame says, "It seems I've been underestimated".
 * "I... am Samurai Gun."
 * Hao Asakura of Shaman King has a minor example with his, "So tiny/small" line. Not sure if this counts since it's not restricted to being said pre-battle; indeed, it's been said as a response to an attack mid-battle, or as a post-battle One-Liner. But it seemed appropriate.
 * Touma From A Certain Magical Index does this always before finishing the current arcs Big Bad

"Greed: I'm sorry, who the hell are you? Izumi: PISSED OFF!"
 * Accelerator has two while curb stomping   and "Sorry, but this is a one-way-road!" (NOTE: the other reading for the Kanji to Accelerators name reads "ippotsuko" or "one-way-road")
 * Fushigi Yuugi: "WHAT--DID YOU DO--TO--MIAKA? I asked you a question, DAMN IT!"
 * Several in Bleach. For example, Aizen before rendering Hitsugaya a bloody mess. "Don't use such strong words. They make you look weak."
 * Ichigo after Orihime cries out for him not to die. He grabs the blade and... "Sorry, Grimmjow. Looks like I can't let you hurt me anymore." *SLASH*
 * Rangiku after Izuru has rendered her sword unusable. "So what if I can't hold my weapon to use it? I just won't hold it. She then proceeds to unleash her shikai and own Izuru with it.
 * Yumichika in Chapter 321. "Thank you". And that was just the start of his Crowning Moment of Awesome.
 * "That was a practice swing."
 * In Tengen Toppa Gurren Lagann, every hero in the show, at one point or another, gets to yell some variation of "WHO THE HELL DO YOU THINK I AM!!"
 * Mobile Fighter G Gundam "THIS HAND OF MINE GLOWS WITH AN AWESOME POWER. ITS BURNING GRIP TELLS ME TO DEFEAT YOU. TAKE THIS! MY LOVE. MY ANGER. AND ALLLL MY SORROW! SHINING FINGAAAAAAAAH SWOOOOOOOORD!"
 * "Life and death may be back to back, but they will never face each other. ...I'll show you. This is what it means to kill something."
 * "Those... really were... dreamlike days. Thank you. But, I'm sorry. I know I'll lose everything. But still. But still... I can't forgive him.
 * The scene in Yu-Gi-Oh where a villain is talking about how he can use his powers to seduce any woman in the world -- after knocking out and planning to rape Tea/Anzu. Yami is waiting by the door, listening to the whole thing: "You think so?" Asskicking ensues.
 * The Toei anime gave Yami Yugi the catchphrase "Saa, GAME no jikan da" (So, it's game time) which usually meant the dice were fixed, the cards were palmed, and you were probably going to wish you could die. The manga translates this to 'Let's play a game' instead. The Manga also has a pair of one liners for him, bookends style. He would open with 'Game Start' and end it with his Pre Asskicking Pose and the Pre-Mortem -I Mean, insanity one liner, Penalty Game.
 * "The first thing I'm going to burn is your tongue." In Fullmetal Alchemist, Mustang says this to Envy
 * Mustang takes this to a higher plane. He pulls one off with the simple words "Too slow," before proceeding to nuke Ed, the stadium, and a whole lot of spectators in a barrage of fiery explosions.
 * Also:


 * And the end of the manga with the fight against Father.

"Cornello: You didn't fool me with that little display down there. Without this, the only alchemy you can perform is to your own metal arm. Edward: You know what? You're not the only one who can't stand doubters, Preach'. Here's the REAL hammer of God!"
 * Since nobody actually got hit, it might not count, but one good line was from Episode 2's penultimate scene, when Ed responds to Father Cornello's underestimation of his alchemic powers by   Cornello only survived this because Ed is the most pacifistic of all main characters, aside from Al. Considering Ed spends about 97% of his time kicking ass, this is saying something.

"Miharu: Yes, we were in the bath together. Kirie: Take a bath... IN! HELL!! (clobbers Yukinari)"
 * This scene was, unfortunately, subjected to a lot of narm in Brotherhood, primarily in terms of animation. Worst of all, though, is that Ed's Badass Boast was changed to a simple, "You want it? You got it!" Combine this with it being changed from the big dethroning moment where Cornello's power is outdone in front of his followers to an ordinary fight scene, and this is pretty big disappointment.
 * The one time of Baccano!! breaks out a Pre-Ass-Kicking One-Liner (in the fourth novel, Drugs & the Dominoes) he makes it count, quoting the first spoken lines of dialog in the history of film: "You ain't heard nothing yet!"
 * Jacuzzi in the anime, right before his traintop beatdown of Goose: "I have a gun...in my heart!"
 * The hot-headed Kirie "Jump-to-conclusions" Kojima of Girls Bravo also does this often anytime she sees the protagonist Yukinari in a hard-to-explain situation.

"Ange: Have a nice dream. See you in hell."
 * "BIG O! SHOOWTIIMEE!"
 * Rebuild of Evangelion
 * I. Want. Rei. Give her BACK!
 * Especially astonishing if you remember all of Shinji's frantic "Move you stinking mecha, or everyone will blame me for the Apocalypse of the Week" - whining in the original Series.
 * 'ZE BEASTO!'
 * "Don't you talk about Sasuke like you own him, especially in front of me, you rotten bastard!!!" -Naruto to Orochimaru, as the second and third tail simultaneously appears...
 * "Didn't I tell you... TO SHUT THE HELL UP?!" -Naruto, angered at Pain's hypocrisy, and then throwing a Rasen-Shuriken at him and the others
 * Naruto  saying "You can give up on... ME GIVING UP!!
 * In Hellsing TV's last episode: "I'll send you to the DEEPEST PITS OF HELL!! While you're there you can LICK THE DEVIL'S ASS!!!!" A very Badass thing to say.
 * ZENRYOKU ZENKAI!!!
 * GET SET. "I'm sorry, and thank you, Erio, Caro. There's nothing to doubt, right?" RIOT ZANBER.*Cha-CHACK.* "Because I was weak, I was hesitating and worrying. I will probably always repeat this. But. That's fine... Because all of that is me."
 * "I found you..."
 * Done by Ange in Umineko no Naku Koro ni :

"Beatrice: You think I'd let him say it!?! Duuumbaaaaass!!!"
 * Also done by Beatrice just before during the second game in the anime:

"Yusuke: For all your careful planning, you made one mistake. You went and pissed me off!"
 * "Don't screw with the traffic police!"
 * "You just went for my head, didn't you. You know, you could've killed me, right? And you knew that, which means you were trying to kill me, right? So no matter what happens to you now, you can't complain, right?"
 * Yusuke from Yu Yu Hakusho. Anyone remember in the beginning when he was fighting Suzaku?

"Yusuke: Alright, if you call off your goons now, I'll only rip out one of your lungs. Suzaku: And if I refuse? Yusuke: Then hold your stinkin' breath!"
 * I seem to recall a really good one from that fight from the English dub that went something like this:

"Yusuke: (about to fire an attack into Jin's that will surely kill them both) Let's see which one of us can take a bigger asskicking!"
 * That fight Yusuke had with Jin during the Dark Tournament Saga:

- What's amusing is Yusuke's follow-up reaction: "Damn! At least one of us should have died!"

"Chu/Chew: What did you say was over? Usopp: This fight! Did you know that grog burns? (Usopp lights Chu up like a Christmas Tree)"
 * Sengoku Basara: "Put Ya Guns On!"
 * Every single character has one or two trademark one liners for use in the event of asskicking. Masamune who says the above also uses "Are You Ready?" and "Let's Party!".
 * Done by Teresa in Claymore. "Say your prayer you wretches. Filth like you is even lower than Youma. I am going to kill every last one of you". Do not touch her Morality Pet, for you are weak against her and Made of Plasticine.
 * Lina Inverse does this quite often.
 * Trinity Blood "Crusnik 02. Nanomachine output 40%. Activate."
 * Cowboy Bebop: LET'S PARTY!
 * Mai-Otome: Rena Sayers from the prequel series. "I'm sorry everyone, but please hang in there. If you look away, you'll die." And boy does she deliver.
 * One Piece has a good one.

"Luffy: And I'm alone. Get out of my way!"
 * The perhaps most epic one: In Enies Lobby, Luffy is informed that its garrison numbers in the tens of thousands.

"Zoro: You want to kill me?! You couldn't even kill my boredom!!!"
 * There's also  Luffy who gives us one with only one word. He's fighting the same exact pacifista that   It shoots a laser made of light at Luffy who remarks; "slow." Then lays it down for good with one jet pistol.
 * Luffy stands atop a building calling out for Bellami who asks Luffy if he "even knows how to throw a punch" causing the observing crowd to burst in laugh, Luffy simply says "you want to know if I know how to throw a punch?" and proceeds to one-hit Bellami, the crowd instantly goes silent.
 * Zoro also has many of these. For example this golden line in the Fishman Island battles, when he fights an eight-sword-wielding fishman. Zoro slices the fishman's swords horizontally and stares very scarily at the merman.

"Matsudaira: Wash your own shitty underwear!"
 * Gintama has a lot, whether they are hilarious lines -

"Gintoki: Don't ever show your face around her again, you sick son of a bitch!"
 * Or serious lines -

"Hitsugi: Now then... Hoshikawa-san... Let us dance!"
 * Rosario + Vampire: Moka's ever famous "KNOW YOUR PLACE!" Followed by a kick to the face.
 * "I hope you didn't see a doppelganger... because, you know, that means you're going to die." Cue the Evil Laugh and a roundhouse kick administered to the bad guy.
 * Hayate Cross Blade:

"Dream Thief: A Meowth that can talk? We'll be rolling in dough! Now just sign this contract..."
 * Meowth gets a hilarious one when he confronts the Dream Thief in Best Wishes!

- Meowth: AFTER ALL YOU PUT ME THROUGH, I WOULDN'T SIGN YOUR REPORT CARD!!! (slashes Dream Thief's clothes off with one attack).

"Achika: I have had enough! I will not allow this! I will pay you back! Because forgiveness... for one like you... could never be an option."
 * In the first Tenchi Muyo movie, Tenchi Muyo in Love, Big Bad KAIN makes the mistake of injuring young Noboyuki in front of Achika. This ends up unlocking Achika's power.
