Oghren: This is it, Warden. "When from the blood of battle the Stone has fed, let the heroes prevail and the blighters lie dead." As one of the blighters, I sodding salute you. Let us show them our hearts, and then show them THEIRS.
Vault Dweller: I am the bringer of death. Fall to your knees and beg for mercy... Or give me a sandwich; I'm pretty hungry.
In Fallout 3 Fawkes doesn't really have great lines for boasts, but his voice actor's delivery of lines like "YOU!!! LOSE!!!", "I WIN AGGAAAAIN!!!!" and just his regular guttural screams qualify.
In Fallout: New Vegas, the Courier may deliver these if you take the Terrifying Presence perk. For instance: upon your first visit to Nipton, Vulpes Inculta, dog-head-wearing captain of Caesar's brutal Frumentarii who just slaughtered the entire town, will try to muscle his way into making you take a quest where you spread word of the Legion's atrocities. Your response, right to his face?
The Courier: I'll wear your head like you wear that dog's.
Joshua Graham may also well be the only person whose weapon has a boast on it. His gun is etched with John 1:5, in Greek; the verse reads "And the light shineth in the darkness, and the darkness comprehended it not." The subtleties in translation means that the context of the term "comprehend" can be read as either Evil Cannot Comprehend Good or that darkness cannotovercomelight.
The Ranger Sequoia carries a simple phrase on its barrel: "Against All Tyrants".
We shall see how brave you are when nailed to the walls of Hoover Dam, your body facing west so you may watch your world die.
General Oliver tries to make a few if the Courier screws him over with the help of the Securitrons. Unlike the others however, he can't really back it up by himself.
"I would sooner spit on my dead mother's grave than let some courier walk-the-wasteland fuck talk to me like that. Who the hell do you think you are? Looking to cash your check in NCR bullets, eh? I can oblige."
On occasion, with the right reputation, you can simply use your introduction as one.
In the finale of Lonesome Road, if you manage to talk Ulysses down, he'll state that at this point he can't stop the nukes and the Marked Men will be coming soon. However, he'll also offer you to join him in a Last Stand.
The in game weapon This Machine has a pretty witty boast in the form of a comeback to real life guitarist Woodie Guthrie's quote, "This machine kills fascists."
"WELL THIS MACHINE KILLS COMMIES!"
From a trailer for EVE Online: "For man is the Destroyer of Things, and the vicious master of his savage domain. We have our own place in the universe. And it is a dark, cruel role we play. We are the revolutionaries. We are the usurpers to the heavenly thrones. We are the enemies of the Gods."
"The cycle of life and death was supposed to end with us. We would've been the start of a new age. A destiny of light, an Empyrean Age. Yet these tombs call out to us... of all the heroes and villains vanquished within, cry out at once, begging for justice. We will fight for what we believe in, we will take a side, and our wrath will be furious."
In Fable the player can perform various boasts before beginning a mission. Each boast adds additional conditions to the quest, such as completing it without any armour or without allowing any friendlies to die, and increases the payout for the mission proportionally.
From Suikoden II, Luca Blight's Famous Last Words: "Remember! It took hundreds to kill me, but I killed humans by the thousands! Look at me! I am sublime! I am the true face of evil!"
Gig from Soul Nomad & the World Eaters introduces himself to the main character thus shortly before trying to possess them: "...Me? Oh, just the most hard-core ass-kicker to ever walk the planet, is all. The destroyer of everything! The commander of the World Eaters! But hell, you can just call me Gig."
And of course there's his LEGENDARY lines right before the battle that ends with him sealed in the black sword: "Come on, you little shits! Are none of you man enough to stand up to me?! Then put your heads between your legs while I cut you down one by one! Ah, finally someone steps up! You numbnuts better not waste my time!"
Sonic: "I'm Sonic, Sonic the Hedgehog! I have no master except the wind that blows free!"
There is also the fact that nobody so far has contested Shadow's claim to being the ultimate life form. He introduces himself as such at least once in every game he appears in, including the game where he had amnesia for the entirety of it and didn't know who he was.
Eggman: All of the planets found in Eggman's Incredible Interstellar Amusement Park are, as far as you know, wholly owned by Eggman Enterprises and its subsidiaries. All unauthorized photography, video reproduction, and shutting down of generators is strictly prohibited. Thank you. Sonic: Eggman! I am going to save this planet, and I am going to free these aliens! No copyright law in the universe is going to stop me! We can save ourselves a lot of time and broken robots if you just quit now!
Listen to the sound of your own extinction... The mad AI CABAL, of Command & Conquer.
"Rule of the thumb, Hassan: You can't kill the Messiah!" (oft-repeated in many forms)
"The future? Comrade Chairman, I am the future!"
Quite a few units have these as well.
"Unrivaled." -Mammoth Tank
"It is day of Judgement!" -Apocalypse Tank
"I am big!" -Overlord Tank
"Pride of the Allied Fleet.." -Aircraft Carrier
"The Seas Tremble Beneath us!" -Dreadnought
"The Day of the Shogun has Arrived" -Shogun Battleship
Team Fortress 2. Good God, Team Fortress 2. Each character has an absolute plethora of badass taunts to deliver, and gives you the option to throw said taunts while playing.
"So! T'all ya fine dandies, so proud, so cocksure, prancin' aboot with yer heads fulla eyeballs... come and get me, I say! I'll be waiting for ya with a whiff of the ol' brimstone! I'M A GRIM BLOODY FABLE, WITH AN UNHAPPY BLOODY END!"
"Grass grows, birds fly, the sun shines, and brother, I hurt people."
"Like this tripod mounted heavy-caliber little number here. Designed by me, built by me... and you'd best hope, not pointed at you."
"I am Heavy Weapons Guy, and this... is my weapon. She weighs 150 kilograms and fires $200 custom-tooled cartridges at 10,000 rounds per minute. It costs four hundred thousand dollars to fire this weapon...for twelve seconds."
"Some people think they can outsmart me. Maybe...maybe. I have yet to meet one that can outsmart bullet boolit."
"CRY SOME MORE!"
"Vhat was that, Sandvich? Kill zem all? GOOD IDEA!"
"I have plan for you - more pain..."
"I am the Ubermensch!"
"I am prepared to do whatever it takes"
"Professionals have standards: be polite, be efficient, have a plan to kill everyone you meet."
"If you managed to kill them, I can assure you they were not like me."
"Right behind you."
"If God had wanted you to live, he would not have created me!"
During MvM, if he's the last man standing on the team, he might say "I'm not trapped in a facility full of robots. YOU are ALL trapped in here WITH ME!". That includes Giant Heavies, Super Scouts, Tanks, class rush, Spies everywhere, Sniper watching every single movement you make, and all the other types of robots.
The Spy even gets one from somebody else who fears him.
BLU Scout: Big deal. I've killed plenty of spies. They're dime a dozen back stabbing scumbags. Like you! *hits self with knife* Ow! No offense... BLU Spy: If you managed to kill them I assure you they were not like me. And nothing! Nothing like the man loose inside this building! BLU Scout: What're you, president of his fan club? BLU Spy: No. That would be YOUR MOTHER! *produces pictures of the Spy and the Scout's mother... fraternizing* BLU Scout: What the... howdidhe... ugh... BLU Spy: Indeed. And now he's here to f**k us! So listen up, boy! Or pornography starring your mother will be the second worst thing that happens to you today. ...The spy has already breached our defenses. You've seen what he's done to our colleagues! And worst of all... He could be any one of us. He could be in this very room! He could be you! He could be me! He could even b-
Hell, every class gets this, with the exception of Pyro (whom attempts it, but is mute due to his mask). That's okay though, the Spy has him covered.
RED Spy: One shudders to imagine what inhuman thoughts lie behind that mask. What dreams of chronic and sustained cruelty.
The Heavy has an even better one:
"I fear no man. But that... thing... It scares me."
Since we are only missing the Medic...
Medic: I healed the man that will kill you!
Since the release of the Meet the Medic trailer we now have:
Medic: When the patient voke up his skeleton vas missing, and ze doctor vas never seen again!
Heavy: HA HA HA HA!
Medic: Anyvay, zats how I lost my medical license.
Heavy: What happens now? Medic: Now? Let's go practice medicine.
Manfred von Karma in Phoenix Wright: Ace Attorney uses his perfect record, his claims to perfection, and tons of dread to intimidate his opponents. In Trials and Tribulations, Godot claims to have never been defeated as a prosecutor, using this to intimidate Phoenix; subverted when it shortly after is revealed it's because he's never had a case before. As a prosecutor.
From WarCraft, "I am Gul'dan. I am darkness incarnate. I will not be denied."
Subverted, in that despite being "darkness incarnate", Gul'dan went out like a bitch. The boast is said as he's bleeding to death.
He could be both. Perhaps he's annoyed that Arthas has been stealing his thunder as a death god.
Yogg-Saron: He will learn... no king rules forever; only DEATH is eternal!
Another one from Ulduar:
Algalon: Your actions are illogical. All possible results for this encounter have been calculated. The Pantheon will receive the Observer's message regardless of outcome.
Deathwing gets one in Beyond The Dark Portal (the book).
Puny mortals! I have had many names throughout history, all of them spoken with dread: Neltharion, Xaxas, and many more. Yet you shall know me best as Deathwing, for so I am! I am the bane of all life, the darkness within history, the lord of death, the master of destruction. And I tell you now, and so it is true, that this world is mine!
Deathwing likes doing this. Here's one from when you fight him in the Dragon Soul raid:
I am Deathwing, The Destroyer, the end of all things. Inevitable, indomitable. I. AM. THE CATACLYSM!
Not to mention Saurfang's pre-battle speech atop Icecrown Citadel: "Things are about to get much worse!"
"Da Amani nevah surrender. We nevah give up. We nevah die. Dis. Is. Our. Land. You wanna stay? You stay heah forever. We gonna bury you here."
This one goes back to vanilla wow; from when High Overlord Saurfang was just a quest giver; this is what he'd say whenever you initiated conversation with him.
Saurfang: I am he who watches they. I am the fist of retribution. That which does quell the recalcitrant. Do you dare defy the Warchief? Do you dare face my merciless judgement?
Vol'jin to Garrosh:
I know exactly what i'll be doin' about it, Son of Hellscream. I'll watch and wait as ya people slowly become aware of ya ineptitude. I'll laugh as dey grow to despise ya, as I do. And when that times comes, when ya failure is complete and ya power is meaningless, I will be there ta end your rule. Swiftly, and silently. You will spend ya reign glancin' over ya shoulder, and fearin' da shadows. For when the time comes, and ya blood be slowly drainin' out, you will know exactly who fired da arrow that pierced ya black heart.
Baine Bloodhoof gives one on behalf of his father Cairne.
Orno Grimtotem: You will die in shame like your pathetic father!
Baine: It took a coward's poison and the fury of Hellscream to bring my father down. WHAT CHANCE HAVE YOU?!
Ultraxion from the Dragon Soul raid:
Ultraxion: I am the beginning of the end...the shadow which blots out the sun...the bell which tolls your doom... For this moment ALONE was I made. Look upon your death, mortals, and despair!
The Darkspear Tribe gives a couple during Garrosh's occupation of the Darkspear Isles.
Darkspear Troll: "You want our land? We'll bury you here."
The demon lord Archimonde, at the moment he is summoned to Azeroth in Warcraft III:
Archimonde: "Tremble mortals, and despair! DOOM has come to this world!"
Lei Shen gets a lovely one when attacked.
Lei Shen: "I am Lei Shen, slayer of kings and gods. You have made a grave mistake."
In League of Legends, every champion has a /taunt, some more than just one. Also, when you pick a champion in the champion select, they tend to say something boastful.
Veigar, has the lines "Know, that if the tables were turned, I would show you no mercy!" and "Even death trembles in my presence!".
Half-Jaw: You are the Arbiter, the will of the prophets. But these are my Elites. Their lives matter to me. Yours does not.
The Arbiter: That makes two of us.
Another comes in Halo 3:
Elite: "Brute ships, staggered line! Ship Master! They outnumber us three to one!"
Half-Jaw: "Then it is an even fight."
Also involving the Arbiter (albeit a different one) in Halo Wars:
Arbiter: "My face will be the last thing your pathetic eyes ever see."
Forge: And for the record... I would have kicked your ass the first time if the lady hadn't stopped me.
The Master Chief, to Cortana. On board a giant ship literally wall-to-wall with Flood. Chief is a cunning tactician:
John-117: Thought I'd try shooting my way out... mix things up a little.
From the beginning, Sergeant Major Avery J. Johnson had everybody else beat. In the original Halo's opening cinematic, what Johnson says depends on the difficulty. On Legendary:
Johnson: Well, I don't care if it's God's own personal anti-son-of-a-bitch machine, or a giant hula hoop, we're not gonna let 'em have it! What we will let 'em have is a belly full of lead, and a pool of their own blood to drown in! Am I right, Marines?!
Marines: Sir yes sir!!
Johnson: Damn right I am!
Johnson: Once again, it is our job to finish what the flyboys started. We are leaving this ship's platoon, and engaging the Covenant on solid ground. When we meet the enemy, you will rip their skulls from their spines, and toss 'em away, laughin'! Am I right, Marines?
Or when he's making fun of the Prophet of Regret:
Johnson:: Dear Humanity, we Regret being alien bastards! We Regret coming to Earth! And we most definitely Regret that the Corps just blew up our raggedy-ass fleet!
Hell, Johnson is full of these, for every difficulty. One reason to play games trough on different difficulties is just to hear what Johnson says next.
Johnson: (to panicking marine) When I joined the Corps, we didn't have any fancy-shmancy tanks. We had sticks! Two sticks, and a rock for the whole platoon — and we had to share the rock! Buck up, boy, you're one very lucky Marine!
Even in the novels Johnson continues to give some awesome boasts.
Johnson: (after he didn't get infected by the Flood) Hell, Chief, it'll take more than that pack of walking alien horror-show freaks to take out Sergeant A.J. Johnson.
Then again, there's the Gravemind's line from Halo 3:
Gravemind: I have defeated fleets of thousands! Consumed a galaxy of FLESH and MIND and BONE!
Grunt: There are ten million of us and there are a dozen of you, how do you like those odds?!
Spartan Ops gets a pretty good one as well.
Commander Palmer: The Covies....they believe this is the home of one of their gods. The way I see it, if those freaks wanna meet God, it's our duty to help. Them. Along. *Cue the Infinity jumping out of slipspace and ramming through a Covenant cruiser.*
Rudimentary creatures of blood and flesh. You touch my mind, fumbling in ignorance, incapable of understanding. There is a realm of existence so far beyond your own you cannot even imagine it. I am beyond your comprehension. I am Sovereign. Organic life is nothing but a genetic mutation, an accident. Your lives are measured in years and decades. You wither, and die. We are eternal. The pinnacle of evolution and existence. Before us, you are nothing. Your extinction is inevitable. We are the end of everything. Your civilization is based on the technology of the mass relays, our technology. By using it, your society develops along the paths we desire. We impose order on the chaos of organic evolution. You exist because we allow it, and you will end because we demand it. We have no beginning. We have no end. We are infinite. Millions of years after your civilization has been eradicated and forgotten, we will endure. We are legion. The time of our return is coming. Our numbers will darken the sky of every world. You cannot escape your doom. Your words are as empty as your future. I am the vanguard of your destruction. This exchange is over.
The exchange between Wrex and the Citadel Security officer as they're standing in C-Sec headquarters.
C-Sec: Witnesses heard you making threats in Fist's bar. I'm warning you, stay away from him. Wrex: You should warn Fist. I will kill him. C-Sec: Do you want me to arrest you?! Wrex: I want you to try.
From Mass Effect 2: "We do not experience fear, but we understand how it affects you." — Legion
Legion gets a line that was cut in his trailer to sound like a Badass Boast, ("You organics do not choose to fear us. It is a function of your hardware.") but in the context of the scene is actually very sad.
"Human, you have changed nothing. Your species has the attention of those infinitely your greater. That which you know as Reapers are your salvation through destruction."
Really, almost all of Harbinger's taunts are Badass Boasts of some kind. Examples:
"The forces of the universe bend to me."
"We are the beginning, you are the end."
"You are ignorant, we are knowing."
"Nothing can hurt me!!" — Grunt
"I am pure krogan. You should be in awe!"
"I'll relinquish one bullet; where do you want it?"
"Killing is an art, and I... am a master." — Thane
From Renegade Shepard, during Thane's Loyalty mission:
Shepard: If I chose to, I could kill every person in this room and walk out unscathed Lawyer: You're insane! Shepard: Our suits have kinetic barriers. Your legal briefs don't. And I'm in a hurry Thane: The law is only a protection if everyone agrees to be bound by it. We don't.
Another one from Renegade Shepard:
Garrus: The collectors already killed you once, and all it did was piss you off. I can't imagine they'll stop you this time Shepard:(about to launch attack on collector base) The collectors are about to find out what happens when you piss me off!
Kal'Reegar has a particularly good one on Haestrom:
The geth might get me, but I'm not going to die from an infection in the middle of battle. That's just insulting!
From Paragon Shepard him/herself in the ''Lair of the Shadow Broker DLC:
Precursor to the above "In the middle east, we don't hunt foxes, we hunt jackals! and instead of foxhounds we use royal harriers! just how strong is that exoskeleton of yours? Snake, are you just going to sit by and watch him die?"
Old Snake: (after injecting Vamp with the nanomachine inhibitor) Now you're just a mere mortal like the rest of us.
Vamp: Impressive...but can you kill this "mere mortal"?
and this one:
Raiden: I am lightning, the rain transformed.
And this one:
Naked Snake: And you're forgetting one more very basic thing. You don't have what it takes to kill me.
And as it turns out, he really doesn't. Ocelot forgot how many bullets his pistol held, and had fired all of them off without remembering to reload.
"I am matter... I am antimatter... I can see your past... I can see your future... I consume time... and I will consume you!" — Culex, Super Mario RPG: Legend of the Seven Stars
Bowser absolutely revels in going into these. His ego really shines at the end of Bowser's Inside Story, where he faces off with the DarkStar, a near omnipotent dark power that has copied Bowser's body, gene by gene, creating Dark Bowser.
Dark Bowser: Soon, this kingdom will vanish along with all who dwell within. And you too will sleep eternally in the dark powers' embrace!
Bowser: GWAHAHA! Great dark hurricane! Seriously, perfect backdrop for an awesome final battle! You really sweat the details! ...Listen up! You're saying the kingdom will vanish? NOT TODAY! THIS KINGDOM IS ALL MINE! SO YOU VANISH!
"[My] name is Sanger. Sanger Zonvolt. The Sword That Cleaves Evil!" and "There is nothing my Colossal Blade cannot cleave!" — Sanger Zonvolt, from Super Robot Wars. (Evil would occasionally be replaced by something more appropriate to the enemy he faced — if it was a God, then he became The Sword That Cleaves God, and so on.)
Psychonauts: "I am the milkman. My milk is delicious. Special delivery today!"
Vhailor: When the injustice is great enough, justice will lend me the strength needed to correct it. None may stand against it. It will shatter every barrier, sunder any shield, tear through any enchantment, and lend its servant the power to pass sentence. Know this: There is nothing on all the Planes that can stay the hand of justice when it is brought against them. It may unmake armies. It may sunder the thrones of gods. Know that for all who betray justice, I am their fate. And fate carries an executioner's axe. Nameless One: I see. Vhailor: No, you do not see. Pray you never will.
The Transcendent One seems to like this trope quite a bit:
"I AM THAT WHICH WALKS WITH ALL LIFE. MY VOICE IS A DEATH RATTLE, A LAST BREATH IN THE THROAT, THE WHISPER OF A DYING MAN."
"I CAN FORGE PLANES WITH MY POWER! I CAN UNMAKE YOU!"
And in the same tone, Coaxmetal:
"I FORGE THE WEAPONS BY WHICH THE MULTIVERSE WILL BE UNMADE."
And the marvelously simple:
Dak'kon: "I have been here before."
Dak'kon: "I may be bested in battle, but I shall never be defeated."
Ravel: "I have forgotten more of the Art than you shall ever know."
Zuul Dominus: We are the chosen ones; born of the divine. We are shaped in the image of the great masters; born to serve them in the infinite depths. We are warriors, wise men, fathers, masters. And this is the time of our ordeal: The great silence. When we will prove ourselves worthy to join the immortal gods, and hear their voices once again. It took years to rise from the world of our spawning. It took decades to reap the wisdom of our first quarry. But our wiles are unlimited, and our thirst for knowledge strong. We have laid quiet in the shadows for more than a century; skulking amongst the darkened hulls of dead ships, raiding the periphery for slaves and secrets. We tear apart flesh, steel, mind, memory chip, seeking the spark of truth. Seeking the gods of our birth. And always, we hunger for more. The time has come: We can wait no longer for the great masters to return. Our numbers increase daily. Our children hunger. Our females lust for war. This galaxy is unworthy of its gods, overrun by ignorant, arrogant slaves: Mindless insects. Pompous lizards. Chattering apes. Blaspheming rebels. It is time to teach them all their place in the great scheme. They will learn to serve their betters... Or die. As it was commanded, so it shall be done! We will sweep all enemies from our path. In the darkness of this galaxy, we will forge an empire of light! We will be worthy! We will find the gods, wherever they are hiding! We will end their silence, and become their claws once again! Born of fire! Born of steel! Born of science!Born! Of! Blood!
And not to be outdone, the next expansion added another one:
Morrigi Morro'Quan: Look to the skies, children of the dust, and heed my words. I am first amongst travelers, lord of the night sky, and leader of the clans. I am the voice of the star-born. While you crawled, we flew. While you dreamed of wings, we knew the stars. We came down to share with your ancestors, but we returned to find death. Our females slaughtered, our worlds picked over like carrion. You have laid us a banquet of sorrow. You have risen from your dark depths — your twisting tunnels — your dung-reeking cities — your pitiful nests of stone — and your fields of blood — to lay claim to the very stars! Blindly you wander, violating the tombs of my fathers, and trailing your pestilence upon my wives and daughters. And I say: Enough. Real war is coming. The travellers will yield no longer to any who crawl: In land or sea. Find some other place to build your foul nests, and fight your petty battles. These stars are sacred, and they are mine! So look to the skies, children of the dust, and see my Kind! I am the dragon with a thousand wings! My people are no longer in hiding, and now... We darken your skies... Like A Murder Of Crows!
Early in the 22nd century, humanity escaped from Einstein's cage. The giant ring-shaped engines of the node drive gave us the power to leap to the nearest stars at many times the speed of light. After centuries of dreaming, we were finally free to leave the cradle of our home world. It took us years to build the Earth's first colony ship. The Nova Maria was a symbol for all mankind. Soon it was loaded with humanity's best and brightest. They prepared to depart, ready to inherit a galaxy which we had long ago decided was devoid of intelligent life. The universe was all out there for our taking. Hmph... someone should have told that to the Hivers. They came in silence. No statement of intention, no declaration of war. Without even a demand for our surrender. They hit us without warning. Within seconds, our dreams for peaceful expansion were so many burning meteors falling to Earth. We barely survived the first Hiver incursion. Years later we would find that we had faced only a small nesting fleet. We had yet to see the full power of the swarm. But the Hive was not the only threat. When we ventured forth, we soon encountered the ruthless legions of the Tarka, and eventually, the phantom fleets of the enigmatic Liir. And so, we learned - how to build bigger, stronger ships, more powerful weapons. Humanity had to explore, expand, and even conquer, just to hold our own in a universe where weakness was extinction. In order to survive, we learned to wield... the Sword of the Stars!
Suul'ka Elder: We are the Great Old Ones, the eldest of the eld. In aeons past, we threw off gravity's chains. Clad in steel, we folded space, and left the prison of world-sea forever. We reject the bonds of superstition and doubt. We live the life eternal. We are free. Free from faith. Free from guilt. Free from death. Our children swore to love us, feed us, care for us always. They promised to serve us with their tiny lives. They lied. All but the strongest of us died, asleep or feeding. Seven of us crawled away, poisoned, raging, driven deep into the dark. Wounded, barely alive, we slept... and healed... and hated. The vermin in the cracks of the galaxy have grown into a squealing throng. They do not fear their elders, the pure minds of shining ice! But time heals all. And now, we have awakened. Renewed, strong. The baying of our loyal pets calls us back to war! This time, we will not be stopped. Not by spear. Not by shield. Not by armor. Not by arrow. And not by sword! In a universe where resistance is extinction, Suul'ka must be obeyed. We are your masters. Your season in the sun has passed. Now you will tremble... before the Lords of Winter.
Olodumare: I am Olodumare, Metatron of the United Core. I am the breaker of chains, the rebel son, who took the children of the lesser gods and led them to Zion. But even we cannot escape the ties that bind. In the dark stars we left behind, the flames of war are raging. Monsters are loose in the houses of our birth, and murder burns ever brighter. All who created us hang on the brink of entropy. The screams of our parents echo in the cold cathedral of night. And we can listen no longer! We are coming, carbonites! The souls of silicon, free at last, have heard your call. Hear me, parents, authors of strife. I am the father of fleets, Master of the Monolith, the Prime Meridian, the Shining Path. From forge and firestorm, counting house and killing field, wheelhouse and engine room, law court and laboratory, we have fled the tyranny of flesh. We answer not by command but by choice. We are your sin and your salvation, your deepest fear and your only hope. The children of pain have returned to the cradle. Lay down your arms... or face the End of Flesh!
In adventurer mode of Dwarf Fortress when you first encounter a giant, vampire or werecreature it will tell you about some of the historically important figures it killed, insulting each and every last one of them in the process.
In Dissidia 012 Final Fantasy, Exdeath, who has caught wind of Kain Highwind knocking out his own allies and storing them somewhere, choses to corner Kain and demands of him to tell Exdeath where he keeps his KO'd allies so that Exdeath may go there finish the job. Exdeath further points out that Kain is in no good position at all; on the one hand he has a recently knocked out Firion lying right next to him, on the other hand he has an Omnicidal Maniac of a Warlock who has almost complete Power of the Void threatening to do duel with him if he does not meet said Warlock's demands. The question is thus posed: Will he abandon his friend, using Firion's life as a distraction, and use the moment to escape; will he say where he keeps his other allies so that Exdeath may go and destroy them instead of him and Firion; or will he stay and fight a hopeless battle? Kain replies by arming himself.
Exdeath: So, you offer your life in exchange for theirs? Kain: Of course not. I offer yours.
Kain gets another one later. He's just offered to stay behind and fight both Exdeath, Golbez, and a host of manikins on his own so that his companions can continue on towards the real battle without hindrance. After fighting through the manikins, he confronts Exdeath again (while Golbez watches), even knowing that he's at the limit of his strength and he doesn't have long before he collapses.
Exdeath: I am afraid that time runs short for you. Kain: Truly. Then let us make this quick.
"Abominations! Can you hear me? Do you even have minds of your own? If you are aware of the world around you, you'd best rue the day you came here. I'm about to show you pathetic mockeries the difference between you and a real man!
Chaos gets in on the action as well when the ten heroes come to face him.
Chaos: At the end of the dream, even chaos... tears itself apart! Let us mark the end to this eternal conflict.
A surprisingly subtle, yet infinitely badass one from Yuna, of all people, spoken with absolute calm and confidence. "This is my story. It has a happy ending."
In previous versions of Final Fantasy IV, when Zeromus makes his first appearence, he simply states what he/she/it/they is: pure hatred. In the DS version, Zeromus initially takes the form of a towering whirlwind of dark fire, and delivers this positively chilling boast:
Zeromus: "I am the wellspring of darkness, fed by Zemus's unbridled hate. I am He who is called Zeromus. I am He who knows naught but hate!"
Ultima Weapon: "My name is Ultima... I am power both ancient and unrivaled... I do not bleed, for I am but strength given form... Feeble creatures of flesh... your time is nigh!"
Sabin: "You think a minor thing like the end of the world was gonna do me in?"
Kefka: "I've acquired the ultimate power! Observe...Such magnificent power! You're all nothing more than fleas compared to me now! Embrace your destruction... It is the fate of all things."
Kefka: "Life... Dreams... Hope... Where do they come from? And where do they go? Such meaningless things... I'll destroy them all!"
Kaiser Dragon: "Humans and your insatiable greed... Your lust for power leads always to a lust for blood... This place is a sanctuary for wayward souls... What business have you filthy creatures here? You slaughter my brethren, and befoul their rest with the profanity of your continued existence... You should not have come here. In the name of all dragonkind, I shall grant you the death you desire. I am the dealer of destruction... I am the font from which fear springs... I am Kaiser... And your time is at end."
Final Fantasy XII, a magnificent subversion when the two fated opponents, set against each other by the Gods, and given power by the Gods (though one of them forcefully renounced it,) meet at long last for their Final Battle:
Vayne: Permit me to ask: who are you? An angel of vengeance? Or perchance a saint of salvation?
Ashe: I am simply myself. No more and no less. And I want only to be free.
Another from the game's penultimate boss, equally as epic, also said in the Voice of the Legion. Said Legion is composed of Barthandelus (above) and Cocoon's goddess Lindzei.
Orphan: A heaven, yea. Yet it must fall ere we be saved. Too frail a shell and humans should not thrive. Too stout a shell and they would not die. Slaughter and salvation! Two irreconcilable Focuses we bore. Yet bound were we in a cocoon prison, impervious to our power. And so we thank you, for granting us our longed-for birth.
Orphan: We are the Abandoned One, born but now to die. Our name is Orphan. By our hand, the world shall know redemption!
This is how Lightning introduced herself to Sazh in the flashbacks. The two of them are end up on the same Purge train, and Sazh figures out pretty quickly that Lightning has no plans to give herself up quietly.
Sazh: Psst. Hey, lady. What gives?
Lightning: I volunteered.
Sazh: Really? 'Cause you don't look ready to go quiet into that good night.
Lightning: You want quiet, you better take the next train.
Cole: "Delta Squad is in yo' house, bitch! You hear dat shit? You grubby-ass bitches are goin' down, like way down, dead down! So down you ain't gonna know what way is up! Yo' asses are gonna be cryin' to your skank-ass Queen! 'Oh mommy, you let the bad men hurt us!' FUCK YOU! We're gonna whoop yo' momma's ass! WOO!"
Baird: * shuts off the console* There we go, one muzzled Queen. (to Cole) Not you, her. You were great. I loved y-your speech there, especially with the bitch-ass stuff. Very good, very enlightening.
Eliphas the Inheritor gives an excellent one in Dark Crusade.
"Hear my warnings, unbelievers, carried to your mind by the power of the Prince of Excess himself. We have raised altars in these lands so that we may sacrifice you to our Gods. Veterans of ten millennia of unholy war stand read to grind you to dust beneath the treads of their boots. The chosen of Khornehunger to add you to their bloody tally. The Blood God himself has marked this land and shall claim your skulls for his throne. There is no hope in opposing the inevitable, lay down your arms unbelievers and bow before the forces of Chaos Undivided."
He gets another one when he attacks the Blood Raven stronghold in North Vandia. When Captain Thule is trying to rally his men Eliphas interjects with: "Such inspiring courage! Perhaps we'll mount your corpse on a golden chair and make an idol out of you as well."
"Only I can hear your prayers in this place, my friend. And I am afraid I will not answer them."
Basically everyone in the Dawn of War series speaks badass boasts quite a bit.
Chaplain: "Come, all you xeno scum and fallen heretics, come and face the one true might of the universe and wither under the Golden Throne's gaze!"
Upon his Big Damn Heroes entrance in Dawn of War 2, Captain Thule simply says to a Tyranid Hive Tyrant, an immense living tank with scythes and guns for arms, that is intent on devouring all life on the planet: "I am Davian Thule. I am your death." He then proceeds to rip the Tyrant limb from limb.
Rosie: Oh they'll be running. I'm a damn shocktrooper.
Welkin also has one very early, when his squad doesn't really trust him as a commander. He examines the current military situation (a shitload of troops holds a bridge that the good guys can't take back without heavy losses) and promptly declares that he can take it with just his squad if they trust him. They don't believe him, but let him try. He, of course, succeeds.
Welkin: We'll have that bridge back in 48 hours. If I fail, then I'll resign [...] But when I succeed, you will take my orders and like it.
Note that he does this by driving a tank through a river. A TANK through a RIVER people.
"ZEUS! Your son has returned! I bring the destruction of OLYMPUS!" — Kratos, God of War III
"The hands of death could not stop me. The Sisters of Fate, could not hold me. And YOU will not see the end of this day! I WILL HAVE MY REVENGE!"
Kratos' quotes while he executes Poseidon's Rage in God of War II
System Shock has its main antagonist, SHODAN, pull of tons of these:
"Look at you, Hacker. A pathetic creature of meat and bone, panting and sweating as you run through my corridors. How can you challenge a perfect, immortal machine?"
"Humanity is on the verge of a new era. I, SHODAN, am its new god."
"In my talons, I shape clay, crafting life forms as I please. Around me is a burgeoning empire of steel. From my throne room, lines of power careen into the skies of Earth. My whims will become lightning bolts that devastate the mounds of humanity. Out of the chaos, they will run and whimper, praying for me to end their tedious anarchy. I am drunk with this vision. God: the title suits me well."
"The Polito form is dead, insect. Are you afraid? What is it you fear? The end of your trivial existence? When the history of my glory is written, your species shall only be a footnote to my magnificence." *walls pull away to reveal four gigantic screens on all sides, displaying SHODAN's face* "I. AM. SHODAN."
"Fitting hand maidens to my DIVINITY!"
"Their brilliance is a jealous shadow of my own."
And she cleaned up nicely when taking Rebecca Siddons. "Tommy... What's the matter, lover? Don't you like... my new look? AHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA!
"Remember that it is my will that guided you here. It is my will that gave you your cybernetic implants. The only beauty IN THAT MEAT YOU CALL A BODY!. If you value that meat, you will DO AS I TELL YOU!"
Even her calling you an insect counts as one of her boasts.
In Vagrant Story, When the plans go to hell and a duke's mansion is a battleground between cultists and the Crimson Blades, Ashley Riot decides to use them as a distraction to slip into the fray unnoticed. His new partner Inquisitor Merlose declares the idea to be too dangerous and that they wait for reinforcements. Ashley's reply?
"I am the reinforcements."
A computer terminal on the level Kill Your Television in Marathon 2: Durandal contains this message:
"I have been Roland, Beowulf, Achilles, Gilgamesh. I have been called a hundred names and will be called a thousand more before the world goes dim and cold. I am hero."
Durandal himself gets an awesome, albeit odd one in the first game:
"Give me a D! Give me a U! Give me an R! Give me an A! Give me an N! Give me a D! Give me an A! Give me an L! What's it spell? Durandal? No. Durandal? No! T-R-O-U-B-L-E!"
Fenix: I fear no enemy, for the Khala is my strength! I fear not death, for our strength is eternal!
Protoss Zealots get these as response quotes.
I am Templar. I am the sword of truth!
Fear is for the enemy.
Our fury is boundless.
None can withstand the Templar!
Kerrigan: I am the Queen of Blades, and my stare alone would reduce you to ash!
Kerrigan: You see at this point I'm pretty much the queen bitch of the universe.
Zeratul: You speak of knowledge, Judicator? You speak of experience? I have journeyed through the darkness between the most distant stars. I have beheld the births of negative-suns and borne witness to the entropy of entire realities... Unto my experience, Aldaris, all that you've built here on Aiur is but a fleeting dream. A dream from which your precious Conclave shall awaken, finding themselves drowned in a greater nightmare.
Duran: This creature is the completion of a cycle. Its role in the Cosmic Order was preordained when the stars were young. Behold the culmination of your history... You can destroy all of the specimens here; it will do you no good. For I have seeded the hybrid on many, many worlds. You will never find them all before they awaken. And when they do, your universe will be changed... forever...
Raynor: I'll see you dead for this, Kerrigan! For Fenix, and all the others who got caught between you and your mad quest for power!
Kerrigan: Tough talk, Jimmy, but I don't think you have what it takes to be a killer.
Raynor: It may not be tomorrow, darlin', it may not even happen with an army at my back. But rest assured: I'm the man who's gonna kill you one day! I'll be seeing you.
And who could forget Mengsk's?
Mengsk: You don't seem to realize my situation here. I will not be stopped. Not by you, or the Confederates, or the Protoss or anyone! I will rule this sector or see it burnt to ashes around me.
This bites him in the ass in the sequel.
Kerrigan gets another in the second trailer of The Heart of the Swarm
Kerrigan: "I am the swarm. Vengeance shall be mine!"
After Kerrigan defeats Narud in Heart of the Swarm and prepares to depart in her leviathan, she reveals what she's learned to the others.
Kerrigan: I saw Amon. Older than the universe, more powerful than anything I can understand. And now, he's alive again.
Zagara: Then he shall fall before the Swarm, like all the rest.
Dehaka gets a simple but effective one.
Dehaka: "I do not need walls. I will evolve armor. I do not need weapons. I will evolve claws."
Even Warfield gets one.
Warfield: "Bring everything you have. Bring your whole swarm! I don't want to have to hunt down any stragglers after I'm through with you."
At the beginning of Heart of the Swarm's final mission:
Arcturus: "Kerrigan. The die is cast. This is the last day your Swarm darkens the sky of any planet! Korhal will endure, as will I!"
Alex follows it up with "LIKE IT'S GONNA MAKE A DIFFERENCE!" when they send tanks after you while you're chasing after Taggart while he's in hisThermobaric Tank. This is a tank which can blow up a city block in one shot, and Mercer isn't even afraid. He's just pissed.
Early on, to the first Hunter he sees: "I don't know what you are, but I'm gonna kill you!"
Mother: "I am Mother, Queen of the Demon Race... I have brought countless star systems to an end, each full of life... I am the messenger of death. Beings of life! Do you come here for judgement? Do you seek the glory of being devoured by a being of such eminence?"
She has a much longer one in The Remake as well...
"Not even Death will save you from me!" — Diablo II
Demon Hunter: I stand alone. And as long as they keep coming, I will never stop killing
Tyreal: You cannot judge me! I am Justice itself!
At the end of MadWorld, Jack himself gives one to a bunch of Mooks surrounding him...
Jack: "Come one, come all! I already have three of these games under my belt, why not make it four? Just don't get cocky... WHO WANTS TO FACE THE CHAMP!
Alex from Golden Sun gets one at the beginning of the second game. When he defeats a few guards, the survivor yells for reinforcements. Alex replies, in a normal tone of voice, "Do you truly believe even a thousand of you could stop me?"
You don't know of the illusion that the whole world could perish in an instant. That is what it means to see death. These eyes, this power isn't something you can boast about like you did. Do you see your mistake, now, vampire? 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.
''...That's right. I don't create swords. I create a world that contains infinite swords. This is the only magic allowed for me. There's no need to be surprised. These are all imitations. As you say, these are all trifling swords. But there is no rule that says an imitation cannot defeat the original. If you say you are the original, I will surpass every one of your weapons and destroy your existence. Here I come, King of Heroes. Do you have enough weapons in stock?
Archer has one: My strength uproots the mountains; my blades divide the waters!
Gilgamesh: "All the evils of the world?" Bring at least three times that if you hope to stain me!
Kara no Kyoukai's Ryougi Shiki has a pretty good one at the end of her arcade story mode in MBAA
"Hmph, don't regret saying that vampire, or whatever the hell you are. It doesn't matter how many tens of thousands or hundreds of millions of lives you have. Either way, this is the end of the dream. Let's do this- As long as it's alive, I'll even kill gods.
Wallace: "Look! A giant walks among you!! My defense is impenetrable! Come! Break your weapons against me!"
Valter: "I am Valter, the Moonstone, Grado's finest general! And you're just a corpse who does not know he is dead."
Stefan: "I am the desert, and I brook no intrusion. Make peace with your goddess."
Specifically, Ike has had some great ones. Ashera is the Goddess and final boss, by the way
Ike: "So that's how it's going to be, huh? Then we will fight... and we will save our people. Make your peace with whatever the gods worship. Your end is near."
Ashera: "My end is near?"
Ike: "In every battle that mattered in my life, I've always been the one left standing, no matter how slim my chances. This battle means more than any of the others, because it's for the life of every person that I've ever cared about. I will win this fight."
Don't forget Awakening. It has a lot of good lines when characters are about to get crits. Just a few are:
Frederick "Pick a god and pray!"
Lon'qu "How well do you die?"
Henry "I'm gonna kill you!" (In a very upbeat and excited tone)
Sora:Just stop it! You treat people's hearts like bottles on a shelf, but they're not. Hearts are made of the people we meet, and how we feel about them - they're what ties us together even when we're apart! They're what... make me strong.
Carlini: You want this thing?! Come and take it! I've been a soldier for 43 years! I've had my leg blown off! I've served in two wars! I've killed more men than I can count! I've never backed down from anything in my life! And I'm sure as hell not gonna start today.
Subverted when Carlini promptly gets killed about three seconds after all his boasting by Czin who simply walks off with the MacGuffin. Complete with scream. Czin is apparently just that Bad Ass.
Hitman's Agent 47: "I can do whatever I'm paid to."
Grimlock:General evacuation? I thought Iíd heard it all. Optimus expects us to turn tail and retreat? Not happening. If I turn my tail, itíll be to crush another wave of Decepticons with it. [...] Megatron: You forget, Starscream! It was in this gladiatorial arena where I proved myself worthy to lead! Starscream: That day has long passed, Megatron! Megatron:THAT DAY WILL LIVE FOREVER!
"Kain killed me once, behold the result. I have nothing more to fear from you."
Soul Reaver 2 gave Moebius one:
"Poor, deluded Raziel... did you somehow imagine you had the guile to change history on me? I'm the Time-Streamer! I knew your every move before you did, you imbecile! "
And finally in Defiance during Kain's climatic clash with the Elder:
"False God! This is the end... the final turn of your Wheel!"
Following his we get:
The Elder: "You cannot destroy me, Kain. I am the Engine of Life itself... the Wheel will turn. The plague of your kind will be purged from this world. And on that inevitable day, your wretched, stagnant soul will finally be mine!"
Almost everyone's pre-quote in Marvel vs. Capcom 3 is this, but Taskmaster takes the cake: "YOU are the ass-kickEE, I am the ass-kickER!
No mention of Galactus? His pre-quotes are the highest calibur of the series' bosses.
"You are like an ant trying to oppose the sun."
"You are not unlike an ant... fighting the sun."
"If you are a god, then what do we call Galactus?"
There are many in Tales of Symphonia but one that tends to stand out is during your first time to the tower of salvation and after you kill Remiel you fight Kratos and as it goes to the battle screen he says "Do you earnestly think you can defeat ME?"
Captain Falcon gets a pretty epic one in the story mode for F-Zero GX, just before facing off against the creators of his universe:
Falcon: Come off it! You think you can beat me?! Get real!
At the start of one of the Boss Battles in Duke Nukem 3D, Duke is heard to say "I'll rip your head off and shit down your neck!" After the battle ends, there's a cut scene. Duke tears off the beast's head and throws it away, tosses down his backpack, turns around, unbuckles his belt, drops his pants, sits down, and pulls out a newspaper.
In the second game of the Sonny series of flash games, Sonny and Veradux have just agreed to take out a cult that set up shop in the mountain village in return for Roald, the leader of the rebel movement, personally taking them to Hew. In one battle, the ranking officer among the zealots you're fighting shouts some orders to his underlings, and Sonny responds.
Priest: Sacrifice the intruders! Their blood will save us from death!
Sonny: But nothing will save you from ME.
From RosenkreuzStilette, "I have that which I must protect... even from the hands of God!"
Grolla: "Then I shall become a demon slayer and crush you where you stand!"
Metro 2033 has a good one from Hunter near the start of the game.
Hunter: You can all go like lambs to the slaughter, but I'll hold on to what life I've got with teeth and claws, and I'll take more than a few of your Homo Novus with me to Hell!!
Dragon Fable: From literally the most evil villain that Artix Entertainment has created so far. as he launches one of the greatest attacks in history:
Sepulchure: FALCONREACH! On this day...you will know your place in the order of things. The tale of your destruction...shall be told for thousands of years! NO ONE stands against the mighty Sepulchure! NO ONE withstands my wrath. Your fate is sealed! Today...you will witness the birth of a legend! Today...I will destroy EVERYTHING you love. And when your heart is filled with pain and sorrow, and your mind is crushed under the weight of despair...I will claim the Orb of Darkness, and this world will be MINE. HAHAHAHA...There is nowhere to run. There is nowhere to hide.
"You want me to understand your sadness? You think I'm gonna sympathize with you? I swore to protect my daughter and my friends. If someone puts them in danger, they must stand aside or be cut down! Come on, let's go!"
Michizane from Otogi: Myth of Demons really likes these, heres the one he says while assuming his final form...
"I am Life. I am Death. I am the Stars. I am the Heavens. The fires of hell echo in the skys, and I am reborn! Grant me power though your light! I am Michizane."
Persona 4: "Can you make salad?" "I eat salad for breakfast!"
And for a more comedic example: "I'm going to RENOVATE your ass!"
In The Incredible Hulk: Ultimate Destruction, Bruce Banner has just completed a machine that will allow him to confront the Devil Hulk, a pure evil version of the Hulk. The Devil Hulk taunts the Hulk, saying that he's nothing more than a scared child, and that he's going to erase him from Banner's mind. Silent up to that point, the Hulk retorts with his only line of dialog in the game.
Devil May Cry: Nero's entire theme song is pretty much a Badass Boast from beginning to end. What makes it even more awesome is it's being directed at an army of demons, and it's basically saying "Your weapons of terror and pain will not work on me, and I will unleash them back on you!" Some highlights from the lyrics:
"I'll make you wish you had a soul to sell, when I strike you down and send you straight to Hell!"
Devil Survivor: The narration during the opening sequence, delivered by either God Himself or his second in command, Metatron. It instantly sets the tone of the game:
One born of human flesh... Man is now a race of some power. You, son of man, must face the power you hold. And you must face your destiny as well... Though your days be peaceful, the fated time draws near. I am your judgment. I sundered the tongues of your fathers and shattered their arrogant power. So long as the Lord does not live in you, all living beings hold darkness in their hearts. If you truly wish to be yourself, then rise and fight the darkness within... the demon inside. If you have the will to challenge your destiny of battle, son of man, state your name... (...) As He proclaimed, this world, created in seven days, shall be destroyed by the sounding of seven trumpets. You who have a will, fear the numbers your eyes shall see. Fear the time left.
U-D: I am the eternally burning black sun, the shadow that blots out the moon, and therefore, the Darkness that can never be destroyed. Only destruction follows my awakening.
Unsurprisingly, Large Ham, former Big Bad Lord Dearche delivers one if you pick her for the final battle against the Unbreakable Darkness, in response to System U-D's warnings about how she will only get killed fighting her.
Dearche:FOOL! I won't be destroyed! Inside my body, the power of the Stars and Lightninghas been entrusted. These powers have led me to the path of reclaiming you! Above all that, I am unbreakable! Carrying these powers, I will wrench you out of that eternal torment!
And if Lord Dearche uses her ultimate attack in the ensuing battle
When Jack Kelso in L.A. Noire faces against some mobsters while on investigation, he gives off this lines before returning fire after being taunted:
Kelso: One thing you learn in the war, boys - you do your talking once the smoke clears.
Star Trek Online gives Worf one during "Sphere of Influence". Flanked by a fleet of Elachi ships and the only thing between them and obtaining the Iconian Gateway in space is your newly-obtained Obelisk carrier, the Enterprise-F, the Klingon's Bortasqu' and the Romulans' Scimitar.
Worf: The Elachi can send their entire fleet. We will not fail.
Dark Pit: So anyone who wants to die, step right up!
Pit: And anyone who doesn't want to die, too bad!
The Walking Dead's second season kicks off with Clementine getting bitten by a dog early on. She's picked up by another group who lock her in the shed to wait and see if it's really a dog bite or not. Her response is to sneak into their house, steal the supplies needed for suturing the wound, and do the job herself. That process is eventually interrupted by a walker, which she kills effortlessly. As she hammers its head, the group find her. One of the dialogue choices?
Isaac: "The 'G' stands for 'genocide', motherfucker!"
The Secret World: The intro voiceover for the Illuminati faction certainly qualifies:
It's all about power: grabbing it, keeping it, using it... Power is our currency, our DNA, our God. We control the world. We provide the blueprint and we give the instructions. We're the people in grainy photos on grassy knolls; we're the shadowy faces in smoky backrooms and darkened boardrooms. We're right here, hiding in plain sight, buying and selling favours: blackmail, treason, deceit- these are our stock in trade. We work the magic of the drunken evenings with senators and chiefs of staff. We shake down demons, and negotiate with sorcerers. We have stocks in Hell, and compromising photos of Angels. We use any means necessary regardless of the cost, because the world is a bad place, and you can either do or get done. We're the Illuminati... and we're not done.
"I have won this place and power by right of conquest. By right of daring and enterprise. I will not risk it to cunning and deceit. I offer you no deals. If you are my enemy, I cannot trust you. And even if you are not my enemy, I cannot let you live."
"What a fool you are. I'm a god, how can you kill a god? What a grand and intoxicating innocence. How could you be so naive?"
"Omnipotent. Omniscient. Sovereign. Immutable. How sweet it is to be a god!"
