Wolverine, after the X-Men have been completely annihilated by the Hellfire Club: "Ok, suckers... you've taken yer best shot. NOW IT'S MY TURN!"
Prometheus from DC comics throws these out with just about every other line of his dialogue, but his boast upon meeting Batman for the second time is one of his best: " I beat you senseless last time just to show you I could. This time, I'm going to hamstring you, lobotomize you with an icepick, and leave you drooling for the others to find. Let's go, Batman."
His first meeting with Batman is similarly great, as it's basically DC's two most badass Badass Normals boasting at each other for three pages:
Prometheus: I've been waiting for you.
Batman: I don't care what you've been doing. It's over.
Prometheus: See, the information on this disk can be downloaded directly into my central nervous system. I have thirty of the world’s greatest martial arts masters right here. And in just a few seconds, all their skills, all their physical prowess, will be mine. I can also reset my helmet lights to produce a disorienting strobe effect. I should tell you: the odds don’t look good.
Batman: For you.
Prometheus: You think so? You think you’re unbeatable? Maybe I should tell you something else: one of those thirty on my disk, Batman…is you… So don't patronize me! *proceeds to kick the living shit out of Batman*
Throughout his first appearance, as he continues to pick off the Justice League one by one, he keeps count with an old nursery rhyme. When Green Lantern and Flash find him standing over a beaten, bloodied Batman, he introduces himself by saying, "Five little Indians. Who wants to be number six?"
His debut issue, in which he murders and impersonates a wannabe hero who'd won a contest to visit the JLA, he uses the dead man's heroic catchphrase as an ironic boast. "Here comes justice."
"You can look and look, but you'll never find me. I'll erase you from the pages of history."
"I took the name because I wanted to take fire from the gods themselves. Steal their knowledge and techniques and use them against them."
He gets yet another one when he meets Superman for the first time: "Brains and brawn. I'm impressed. You know, it's weird hearing you say the name. It's like I actually made it. Superman said "Prometheus" and he didn't sound scared. You should be. I'm here to take my rightful place in this gallery as the greatest super-criminal who ever lived. The one who killed the Justice League."
Prometheus: *something to the effect of "kill yourself and I'll save the innocents*
Superman: Save these people first. Then I'll do what you want. You owe me that much.
Prometheus: I don't owe you anything, you pompous monstrosity. You know who I am? I'm the ghost haunting your dream house. See, "justice" killed my parents. I was… pretty traumatized. I'm sure you understand.
The Mighty Thor hands these out like candy on Halloween. See his page for details.
Thanos is also good at these, especially when written by Jim Starlin.
"I'm Wilhelmina Murray. I've seen off Count Dracula, Professor James Moriarty and the Martian Invasion of 1898."
Century: 2009 features an incredible one from God (Mary Poppins) to the Antichrist.
I rocked the fretful baby gods to sleep before time started... and I am companion to the women who paste up the stars. The quarters of the world are bound unto my compass. I have taken tea with earthquakes. I know what the bee knows... and you really are a dreadful little boy.
Also, "There's a book about me in the Bible!" "Just the one? I'm on every page."
Final Crisis is full of these, but Darkseid gives a definitive Badass Boast in #5 after taking over the minds of the world's population and defeating the heroes, starting with a completely black panel filled with the words "I. Am. The. New. God." Also, obviously, A God Am I.
"I am the mother of Odin's stallion, Sleipnir. I am the father of Fenrir Sun-Eater, and of Hel Half-Rotted and of Jormungund the World-Serpent. I am Loki Scar-Lip, Loki Skywalker, Loki Giant's Child, Loki Lie-Smith. I am Loki, who is fire and wit and hate. I am Loki. And I will be under an obligation to no one." — Loki (duh)
And, from the same world: "I am of the People, man. My teeth are sharp enough to cut bone. I can run on four legs as well as two. I am kin to dwarrow and nightgaunt. I owe allegiance to none and I fear no man born. I want the woman." — Vassily of the People
Also from the same world, the Furies/Kindly Ones/Erinyes/Eumenides/whatever have a lot of these. Probably the best example is: "We have no nightmares. We are the hounds of Hades. Gods fear us. Demons fear us. We have hounded kings and angels. We have taken vengeance on worlds and on universes. We are the Kindly Ones. We are the Eumenides."
Neil Gaiman is good at these. During the first The Books of Magic, Zatanna takes Timothy Hunter to a party attended by a wide variety of powerful evil magicians. We are led to believe that everyone at the party is either Affably Evil or a Punch Clock Villain on their off time, or both, until the party's host announces Tim's presence and announces that a hefty price has been put on his head ("Which need not be attached to his body"). Things are pretty tense until all of a sudden, John Constantine appears in a doorway, and everyone stops to watch him calmly light his cigarette.
John Constantine: "No one touches the boy. That's right, the boy's mine. And in thirty seconds, me, and him, and the witch are going to walk out of here. You know who I am. Or you ought to. You know my reputation. Now, does anyone really want to start something?" (Nothing happens) "Right. Come on, you lot. We're moving."
"Of all the creatures in the vastness of the universe, there is none like me. I was present at the birth of the universe, and I shall be there at its end. Though I ravage worlds to live, I bear no malice to any living thing. I simply do what I must to survive. And why must Galactus survive? For, no matter how many worlds I devour... how many civilizations I destroy... it is my destiny to one day give back to the universe — infinitely more than I have ever taken from it. So speaks Galactus."
The Crow, explaining himself to a cop: "I am pilot error. I am fetal distress. I am the random chromosome. I am complete and total madness. I am fear."
The Authority: "I've already played this fight in my head a million times, from every angle. I know every move you'll make and how to counter it. I know how to kill you. You've already lost, you just don`t know it yet." Eventually, he starts handing it to people on a card.
Midnighter (to a superpowered Mook holding a child hostage): "Let me make this situation clear for you. I know what special abilities you have. I can see the enhancements. I can detect the increased electrical activity in your brain. I know what moves you're preparing to make. I've fought our fight already, in my head, in a million different ways. I can hit you without you even seeing me. I'm what soldiers dream of growing into. I'm what children see when they first imagine what death is like. I'm the Midnighter. Your Move.
The Big Bad of the "Shiftships" arc has one hell of a boast, which he delivers while curb-stomping Midnighter:
Regis: I can see inside your head, white boy. Did you think your little fight enhancements would let you kill me? You've never fought anything like me, boy. I am Regis. I have been raping and killing better humans than you for half a millennium. That's it. Fight me. Try to hurt me. I've lost count of how many men's fingers and women's nails have shattered on my skin. Your mothers and sisters will bear my children. You cannot stop me. Burn Albion, burn Europe— it won't matter. I am Regis, warrior king of this entire filthy planet— and I will wipe myself with your skin when I'm done violating yours.
Spider-Man in Avengers: The Initiative. "Not gonna happen. Know why? Because I'm Spider-Man. And you're just a dollar-store version of the Lizard. See, I beat down guys like Doc Ock, Sandman, and Venom all the time. And you're just not in their league. Oh, I'm going to win."
Mr. Fantastic: (watching Spidey work his way through pro-reg forces) Amazing. Spider-Man: (giving Reed a flying kick) Spectacular.
Usually, however, Spider-man inverts it, as his badass boast typically starts the instant he shuts up.
In Amazing Spider-Man #369, ol' Webhead says this to his latest foe:
"I'm sorry, you think defeating me is that simple? Have you seen my resumé? I've fought mutants, gods, aliens, technomalogical wackjobs, street hoods... Hell, I fought my own costume. You think it's that simple? Bring it on."
Morningbright in Top 10: Smax: "You see, it's like this. In the beginning, God created me... Then he made the universe from what was left."
"That's why I'm the best. Because I know how to fight like it's life or death... I once swam a mile with three bullets in my lung. I KO'd the Ultra-Humanite with one punch. I am Ted friggin' Wildcat Grant. This is my ring. These are my people. And tonight, for one last time... I am their champion."
A pillar in his lair bears this line from an old poem I am Ozymadias, king of kings. See my work ye mighty and despair.
The irony, of course, is that it's taken from a Percy Bysshe Shelley poem showing how great works crumble over time. In the original context it becomes:
And on the pedestal these words appear: My name is Ozymandias, king of kings. Look upon my works, ye mighty, and despair. Nothing beside remains, round that colossal wreck The Lone and level sands stretch far away boundless and bare\\
Subversion in Calvin and Hobbes: "S for Stupendous! T for Tiger, ferocity of! U for underwear, red! P for Power, incredible! E for Excellent physique! N for, um, something, well I'll get back to that. D for Determination! U for... wait, how do you spell this? Is it 'I'?"
"Look at my eyes, churl. No power... yours or anyone's... can stop me. My ancestors were wizards and kings... conquerors. You are a common killer — a mad dog accidentally born in human form. You took my world, made my people slaves, and slew the man I had given my heart to. I need no power to destroy you — save the strength born in my blood." KRRAK!
Tyr and Thor are having a contest that suddenly turns deadly by Thor's latest attempt to catch the Midgard Serpent. Tyr forgets the contest and starts acting like the God of War (Leaders) he is, snapping orders to help Thor. Thor's sidekick Tjatse doubts him... noting that they just learnt Tyr is of the Giants.
"I was born a Giant! I chose to be an Aesir!
Likewise, in another story Loki makes the mistake of actually pissing off Heimdall seriously. He tries to hide by shapeshifting into a mole, but Heimdall is the God of Watchers...
(stabs his sword down into the soil, one millimetre before the nose of mole-Loki) "I can hear you, Loki!"
Loki is very fond of Badass Boasts in that comic. All the stories that feature him (which are the majority of the stories) has him praising himself at every chance he gets and more often than not ending up getting called on it or having circumstances prove him wrong.
"Hear me, X-Men! No longer am I the woman you knew! I am fire! And life incarnate! Now and forever — I am Phoenix!!"
"Behold your creation, Charles Xavier! I am what was, what is, what will be! I am the Black Angel, Chaos Bringer! I AM POWER!"
X-Wing Series: Wedge has a bit of introspection at the start of one comic; it's not proper boasting because the whole issue is sad in tone, but without context it certainly looks like this trope. "I survived the Battle of Yavin. I survived the Battle of Hoth. Hell... Just a couple of weeks ago I blew up the Death Star during the Battle of Endor. The reason I'm still breathing when a lot of other good Rebel pilots aren't? Maybe it's because I'm better. Or maybe I'm justlucky."
"Lay down your arms! I'm serious and I have the firepower to prove it! Sworn protectorate of over fifteen thousand submarine states. My territory surrounds every continent on the planet. I rule most of this planet's surface and almost all of its depths. So don't even think about picking a fight with the King of Atlantis."
The Incredible Hulk: Bruce Banner once forced Wolverine and Daken to back down when he explained to them what it means to be one of the smartest people in the world and be dangerously unstable.
Maybe the real reason I became the Hulk... was to protect the world from Banner.
I will unleash a terrible fury and do things to you that will make God cry.
Fables: "You dumb bastards! I'm Snow White! I run Fabletown and I'm never outgunned!"
And, later: "Brandish thinks his heart is cold and tough? Mine's been made of stone since I was a child. Monsters of the woods couldn't kill me. The armies of kings, sorcerers and empires couldn't. I'm Snow Goddamn White. I look after myself. I look after my own. And I never lose."
Frau Totenkinder gets one toward the end of the March of The Wooden Soldiers: "I was always stronger than you thought. Killed a dozen times, but it never took. Even burned to ashes in my own oven, I came back, after a good while. How's that for a frail old biddy, eh? Now you hush and let me finish my knitting. Time to stop struggling and let the deep darkness take you. Your stories are all done, Baba Yaga."
"My name is ________. I'm The Flash. The fastest man alive."
Quicksilver gives a lengthy one when fighting Mr. X, but it ends with him explaining the situation. The pauses indicate Mr. X being struck with an iron bar.
You can read minds enough to be able to predict any attack your opponent will make. So you will be able to — anticipate every move I make — and do absolutely — nothing about it — because -I-am-the-fastest-man-on-earth.
Ultimate Quicksilver was really great in the first two volumes of The Ultimates; after the US is invaded by a hostile army of foreign superhumans, he saves Hawkeye from the enemy speedster by dragging her along with him until she vibrates apart, at the same time delivering what must be the fastest badass boast in history: "You want fast, Hurricane? I'll give you fast. What kind of limits did they take you to back home? Mach five? Mach ten? I was hitting those numbers when I still had pimples. (...) Feel your bones rattling like you're on a freight train? That's molecules dancing. That's what happens when you threaten my friends!" The kicker is that he apparently does saves like that all the time, but nobody notices it and few people believe it when he tells them because he does it so fast.
I'm 26 years old. I've been to the Moon, and Mars, and Venus. I've slept with asteroid gypsies, broken sloats, and fought with the eighth insurgency on Forest. I shot a man on Khargu because he needed to die more than any I've ever met. I repaired three rocket tubes with a wrench and a knife while hanging upside down over Titan during the syzygy. I'm 26 years old and my life is over now. So direct me please to the man who'll sell me a gun, and the place where my dad was shot dead in his sleep, for I have business to attend to before I lay down in my grave.
Michael: Was it not Buddha who heard a sermon in the thunder?
Lucifer: Actually, it is in the Upanishads, but I applaud your ecumenical impulse.
Michael: And the words the thunder said were Datta, Dayadvam, Damyata. Give, sympathize and control. I've always thought of that as one commandment rather than three.
Lucifer: Why do I feel that this particular sermon is being preached at me? I can do control. Nobody is good at everything.
Lucifer: A sermon in the thunder, Michael? Thunder only has one thing to say: it tells us how close the storm is.
A Hellfire Club mook has just shot Kitty Pryde, who just freed Logan and Colossus from power draining cages, with a stun rifle.
Wolverine: Sucker, you just made the biggest mistake of your life. (SNIKT) And the last.
Marvel Adventures, unlike the 616 universe, does not need wanton assholery to be badass:
"My name is Reed Richards. And these are my toasters." (curbstomp)
In Marvel Star Wars, Luke once deliberately activates an Imperial droid's capture programming with this.
"Yoda said it, Artoo: There is no try! Only do.. or do not! And I mean to do! This can't stop me!Nothing's going to stop me! I'm Luke Skywalker... destroyer of the Death Star! I'm the one who dueled Darth Vader and lived to tell about it!"
While "I'm the strongest one there is" is the Hulk's catch phrase boast, recently he's simplified it. When told he can't do something, or asked how he thinks he can do something thought impossible, he responds "Sure I can/Easy, I'm The Hulk."
Also, as the Maestro, he had this excellent villainous version;
Maestro: "No, by beating them to death, and it all went so quickly that I'm sorry I didn't prolong it." "You're fighting the inevitable, Hulk. I'm simply the final product of natural selection. The strong survive. I'm the strongest. I survived. When you go against me, you go against the laws of nature."
In Akkad and Elam they called me Baarish-Shammon, and when they threw their children alive into the fire-pits it was my name that was on their lips.
In Egypt - in the reign of the heretic pharaoh Nephren-Ka - they called me 'She Who Stalks By Night', and they dressed my statues in the flayed skins of slaves to keep me from their doors.
In Kadath in the Cold Waste they knew and feared me. My true name is written on the walls of the tombs of Hidden Irem, where no human eye has yet to read it.
In Carchemish and Ashur, in Kiran and forgotten Sarnath, in Luxor and Ib. On the shores of Hali. In the darkest abyss-cities of Shaol.
In all these places, I was fear. I was despair. I was all this, and still so much more.
And you're still dumb enough to think you can beat me?
The Wreckers from the various Transformers comics. There's a particularly good one in "Stormbringer".
Lost cause? Of course it's a lost cause! That why we're here.
The Juggernaut or rather Colossus, after becoming the new Juggernaut gets one as his internal monologue, while fighting Null, Breaker of Stone who is the previous Juggernaut, possessed by an Asgardian demon
His lightning could incinerate armies. My bones crumble beneath his fists. He is stronger than me. He is faster than me. He is more powerful than me in all ways but one. He cannot stop me. How could he? I can't even stop myself.
Doctor Strange does these relatively rarely, so when he flexes his muscles it really gets your attention.
Hear me well, Bruce... Your anger means nothing to me. I am the SORCERER SUPREME. I could snuff the feeble flame of your mortal life with the merest twitch of a finger.
And the arguably scariest Dr. Strange villain of all, Zom (How scary? He was imprisoned once by a coalition of beings including Dormammu and Eternity - which is the equivalent of God and Satan teaming up to take someone out), after being freed from his dimensional prison: "Let the worlds within and the worlds without tremble in their orbits!"
"I have been through death and conquered it. I have returned with my power multiplied. The dark side of the Force lives and manifests itself through me! I reach into the dark side now and send ripples through it to all who serve it — know that I live!"
Darth Krayt, Dark Lord of the Sith
Marvel Boy had a great one:
I'll show you people what paradise looks like if I have to level every city on Earth and rebuild it stone by stone.
Birds of Prey: Barbara to Savant, after the latter broke out of Arkham. Over the phone.
Oracle: You've escaped, and you think the world's a huge place, and you can hide anywhere, right? I'm here to tell you...that world? I own it. Your world is getting smaller by the second. And you can't hide anywhere from me. Every database, every security cam, every police band has my fingerprints on it. Every moment you're out the noose pulls tighter. And Savant, just in case it's not crystal clear by now...nobody messes with my partner. Savant: (trying to hide his face from a security camera) She's overestimating herself. She can't...I'm certain that...[runs away like a scared rabbit, without even bothering to hang up first]
First thing the main character of Orc Stain says is:
After ending the Annihilation event by killing Annihilus with his bare hands, Nova had brought the event up on several occasions. At one point he threatened Blastarr by reminding him that he could easily repeat the act on Blastarr if he does not act diplomatically. But the most famous instance was directed at Tony Stark.
Nova: I pulled him inside out and saved the universe. What have you done lately, Tony?
Kara: Look — here's the problem. You've done some bad things, but I'm really, really upset right now. So much so that, honestly, I don't trust myself. And if you attack me or I attack you... I will hurt you. I will hurt you worse than you've ever been hurt in your whole life. I can carve you up by looking at you. I can break you, boil you, freeze you. I can do things you can't imagine. Things I can't imagine, until I have to, and then I'll improvise. Part of me is hoping that you will attack. And part of me is praying — for your sake and my own peace of mind — that you don't. It's up to you. Oh... And, Rebel... I have eyes that can see through solid matter. I have ears that can hear your slightest word, your heartbeat, your breathing. You do anything that hurts others... I will find you. And you won't like it. Do we have an understanding?
Rainbow Dash: I don't know if you've noticed, but I'm pretty awesome. I'm Pony Newman's Hickory-Infused Awesomesauce[tm].
In Buffy the Vampire Slayer Season 8, after neutralizing his special powers, Willow tosses Dracula his sword, which is intercepted by an enemy vampire. As Dracula takes the sword away from the vampire and uses it to slice him up, the following exchange happens.
Toru: Just like an old man. He needs his cane to stand. Doesn't know what to do with himself now that he's an ordinary vampire. Like the rest of us.
Dracula: My boy...I was never an ordinary vampire. Or did you forget who I used to be? I've killed more men than God's plagues combined. And that was before I started eating people for fun. The fields of Europe used to steam with the blood of my enemies. Trust me...the vampire's the least of your concerns. It's the old man you need to worry about.
In DC One Million, Vandal Savage's dialogue seems to consist of a string of badass boasts loosely held together by plot. (They get less justified as his plans unravel.)
Savage: I remember a world without the wheel. I have seen empires bloom and wither and die. Brief as flowers. And periodically, I have chosen to rule the Earth... This time, I decided to wait until the competition was big enough and arrogant enough to make it worth humiliating...
Savage: Like all specialists, your dependence on one weapon makes you vulnerable. I'll demonstrate.
Savage: I planned and fought and won battles you have only read about in your history books, boy. You're no tactician.
Arsenal: I'm coming back and you're gonna pay! Savage: I paid for all this a long time ago; it cost me sixty barge loads of silver in the days of Thutmose. Look. The time has come for you to die, little boy soldier.
Savage:He trembled before those monsters of evolution. I destroy them with a wave of my hand! Look, Hitler, look!
In the summer special '97 of Paperinik New Adventures, the Evronians bait Xadhoom to one of their bases,and the commander declares the party is over for her. Her response?
Xadhoom:"This is where you are wrong, Evronian! Look at me...I'm all alone,in the heart of a enemy base, surrounded by thousands of warriors. The party for me begins NOW!"
Finnegan Sinister, last of the lyrical gangsters, of Sinister Dexter lives by the Badass Boast.
"You pukeholes made a serious life error rolling in on us. We're dead-eyed lead-sowers from the banks of the Styx and our guns are always hungry. You don't be messin' with us."
Invincible, while fighting Conquest, who's physically superior to him in every way: "I don't care how strong you are. I don't care how fast you are. I can see the future... you don't live to see tomorrow."
Shadow: "I am Shadow the Hedgehog. I am the union of ideals dark and benign but ultimately built in the name of love. I am the Ultimate Life Form. I am the protector of Mobius. Run home to your master and tell him. This is who I am."
"I raise my voice, and Satan himself is on bended knee. I am The Leader of the free world, you impotent little psychotic. I've had the most powerful beings on this or any planet gunning for me for years, and you think you're going to scare me?"
And to Superman:
"I'm the only sane inmate of Asylum Earth. I'm not eager to hand tomorrow over to an interplanetary extremist with laser eyes. There's only room on this world for one leader, Superman. When I'm finished with you, every last gibbon out there will know you for the menace you are... and they'll realize that Lex Luthor is their savior."
"When humanity first looked into the night, my eyes looked back. When they learned to fear the darkness, it was me they feared. When they learned to fight for their lives and their loves and their children, I was their first enemy. Lay your claim to a thousand thousand worlds...this one is mine! FOR I AM THE TIGER!"
My name is Ringo Chen and I kill people for money. It’s my life. My whole life. From the cradle to the grave I know is waiting. A constant dance of bullets, blood and death. I am better at this work than anyone I know of. A simple fact.
