Badass Boast/Live-Action TV

"Delenn: This is Ambassador Delenn of the Minbari. Babylon 5 is under our protection. Withdraw... or be destroyed! Enemy: Negative. [...] Do not force us to engage your ship. Delenn: Why not? Only one has ever survived battle with a Minbari fleet. He is behind me. You are in front of me. If you value your lives, be somewhere else!"
 * Babylon 5 -- "I am Susan Ivanova. Commander. Daughter of Andrei and Sophie Ivanova. I am the right hand of vengeance... and the boot that's going to kick your sorry ass all the way back to Earth, sweetheart! I am Death Incarnate... and the last living thing that you are ever going to see. God sent me."
 * She actually makes a minor habit of this sort of thing: "On your trip back, I'd like you to take the time to learn the Babylon 5 mantra: Ivanova... is always right. I will listen to Ivanova. I will not ignore Ivanova's recommendations. Ivanova... is God. And, if this ever happens again, Ivanova will personally rip your lungs out! Babylon Control out."
 * Followed by an upward glance towards the aforementioned deity, and an off-the-mic, "Just kidding about the 'God' part. No offense." which was such a contrast to the immediately previous awesomeness, that it only made the whole thing funnier.
 * And even earlier, Delenn did one for her world's entire military:

"Michael Garibaldi: "Something's happened to your abilities. You're not a P5 anymore. Hell, you're not even a P12. You're the strongest telepath that I've ever seen. What did the Vorlons do to you, Lyta? Who .. what are you?" Lyta Alexander: "I've only recently begun to understand it myself. You know the Vorlons used telepaths as weapons during the Shadow War, but what no one stopped to consider was that in a war, you have a certain number of small weapons, a certain number of medium-sized weapons ... and one or two big ones ... the kind of weapons you drop when you're ... out of the small weapons and the medium weapons and you've got nothing left to use." Michael Garibaldi: "Someone like that would ... be the telepathic equivalent of a thermonuclear ... device, a ... a doomsday weapon." Lyta Alexander: "Pleased to meet you, Mr. Garibaldi.""
 * And on another occasion, Marcus Cole explained to a group of thugs why they should tell him what he wanted to know: "Because if you don't, then in five minutes I'll be the only person at this table still standing. Five minutes after that, I'll be the only person in this room still standing. So, who's in?" After he makes good on this threat, he laments that "Bugger now I have to wait for someone to wake up."
 * It gets better in the RPG. Whenever Minbari Rangers meet, they do this. Why? Because they have a loose hierarchy. Whoever is most badass is team leader.
 * Lyta Alexander loves to play with this trope:

"Lyta Alexander: "You cannot harm me. You cannot stop someone who's been Touched by Vorlons." ] John Sheridan: "You're not the only one that's been touched by the Vorlons.""
 * Finally, her boast gets countered:

"The Doctor:"
 * The new series shows that the Doctor can do these indirectly and evil will retreat.

"The Doctor: (As one of the Monsters of the Week gets to watch the records of him kicking ass on every kind of alien to mess with Earth, ever.) I'm the Doctor. Basically... run."
 * Similarly, from the Eleventh Doctor's premiere...

": I looked into the TARDIS and the TARDIS looked into me. I am the Bad Wolf. I create myself. I take the words...I scatter them, in time and space. A message, to lead myself here. I want you safe, my Doctor. Protected from the false God.
 * River Song and a Dalek in The Big Bang: "I'm River Song. Check your records again."
 * gets one too, in The Parting of the Ways when
 * You cannot hurt me, I am immortal.
 * You are tiny. I can see the whole of time and space, every single atom of your existence. And I divide them. Everything must come to dust. All things, everything dies. The Time War ends."

"The Doctor: No! 'Cause this is what I'm going to do: I'm going to rescue her! I'm going to save Rose Tyler from the middle of the Dalek fleet! And then I'm going to save the Earth! And then, just to finish off, I'm going to wipe every last stinking Dalek out of the sky! Dalek 1: But you have no weapons! No defenses! No plan! The Doctor: Yeah! And doesn't that scare you to death? Rose?
 * Earlier, at the end of the previous episode:

Rose: Yes, Doctor?

The Doctor: I'm coming to get you."

"Rose: Oh, look what the cat dragged in. The Oncoming Storm. Doctor: You sound just like your mother!"
 * Older Doctor Who series also had these, usually delivered by Tom Baker. "I am a Timelord. I am not a human being. I walk in eternity."
 * "Do you know what they call me in the ancient legends of the Dalek homeworld? 'The Oncoming Storm'. You may have removed all your emotions, but I bet that deep down in your DNA there's one spark left, and that's fear."
 * Later subverted when Rose is captured by some clockwork robots, and the Doctor is elsewhere. She tries (unsuccessfully) to basically redo his "Oncoming Storm" boast by proxy, but gets drowned out by a very drunk Doctor bursting into the scene just in time.

"The Doctor (whilst chasing a Clockwork Robot): Even monsters have nightmares! Reinette: What can monsters have nightmares about?! The Doctor (as he chases it back through the fireplace): ME!"
 * "Well, you need to get yourself a better dictionary. When you do, look up 'genocide.' You'll find a little picture of me there, and the caption'll read 'Over my dead body.'"
 * Of course, you'll also just find a picture of him. Mostly against the Daleks though.
 * Also the Racnoss and, oh, his own species.
 * From "The Girl in the Fireplace":

"I shall never die! The thought of me is forever! In the bleeding hearts of men, in their vanity and obsession and lust! Nothing shall ever destroy me! Nothing!"
 * Also from Doctor Who, The Beast:

"Rose: Go to hell!"
 * And the badass retort:

"Cyber Leader: Daleks, be warned. You have declared war upon the Cybermen. Dalek Sec: This is not war -- THIS IS PEST CONTROL!
 * And of course nearly everything the Daleks say for the Villain to Hero variety. Or in the case of the episode "Doomsday", Villain to Villain:

Cyber Leader: We have five million Cybermen. How many are you?

Dalek Sec: Four.

Cyber Leader: You would destroy the Cybermen with four Daleks?

Dalek Sec: WE WOULD DESTROY THE CYBERMEN WITH ONE DALEK! You are superior in only one respect.

Cyber Leader: What is that?

Dalek Sec: You are better at dying."

"Davros: We shall become all-- The Doctor: -Powerful! Crush the lesser races! Conquer the galaxy! Unimaginable Power! UNLIMITED RICE PUDDING! Et cetera! Et cetera!"
 * In this case, Dalek Sec is not only boasting, but making an objective statement of fact. The odds really were that one-sided.
 * From "Voyage of the Damned": "I'm the Doctor. I'm a Time Lord. I'm from the planet Gallifrey in the constellation Kasterberous. I'm 903 years old, and I'm the man who's going to save your lives, and all six billion on the planet below. You got a problem with that?"
 * A quieter variation took place in Planet of the Dead, where the Doctor calmed down the passengers of a bus trapped on a distant planet after their bus-driver died trying to pass through the wormhole, by reminding them of their lives back on Earth. This time around he was more able to keep his promise: "That planet out there, with three suns, wormhole and alien sand, that planet is nothing--you hear me, nothing--compared to all those things waiting for you. Food, home, people--hold on to that. 'Cause we're gonna get there. I promise. I'm gonna get you home."
 * The Eighth Doctor in the audio adventure "Phobos": "Was that supposed to frighten me? I've seen entire species destroyed, civilisations left in ruins. I've witnessed solar systems vanish in the twinkling of an eye. I've seen things that would freeze your blood. So don't threaten me. Don't ever threaten me."
 * Also from the Eighth Doctor, in the novel "The Dying Days"; "I am the man that gives monsters nightmares. The Daleks call me the Bringer of Darkness. I am the Eighth Man Bound. I am the Champion of Life and Time. I'm the guy with two hearts. I make History better. I am the Doctor."
 * Davros tries:

""Resist the Canisians. Breathe harder to starve them of air, and as they kill you bleed on their boots. Offer them no compliance, no words, no recognition of existence.""
 * And (goodness there's a lot aren't there) from the audio "Death Comes to Time", a commander gives orders to his men about a battle they all know they're going to lose.

"The Doctor: There's one thing you never put in a trap if you're smart. If you value your continued existence, if you have any plans about seeing tomorrow there's one thing you never, ever put in a trap: Angel Bob: What's that sir? Doctor: Me."
 * And in "The Family of Blood", Tim Latimer makes a badass boast on behalf of the Doctor: 'I've seen him. He's like fire and ice and rage. He's like the night, and the storm in the heart of the sun. He's ancient and forever... He burns at the center of time and he can see the turn of the universe... And... he's wonderful.'
 * "The Time of Angels" have another, with his response to the Weeping Angels taunting him.

""Hello Stonehenge! Who takes the Pandorica, takes the universe! But, bad news everyone, 'cause guess who! HAH! You lot, you're all whizzing about, it's very distracting. Could you all stay still for a moment, because I! AM! TALKING! Now the question of the hour is who's got the Pandorica. Answer: I do. Next question: who's coming to take it from me? Come onnnnnn! Look at me, no plan, no backup, no weapons worth a damn. Oh, and something else: I don't have anything. To. Lose. So! If you're sitting up there in your silly little spaceships with all your silly little guns, and you've got any plans on taking the Pandorica, tonight, just remember who's standing in your way. Remember every black day I ever stopped you. And then, AND THEN, do the smart thing. Let someone else try first. *Cue shot of spaceships flying away*"
 * And from "The Pandorica Opens", we have this speech, delivered to a swarm of hostile spaceships containing every single one of the Doctor's many enemies above Stonehenge.

"Doctor: There was a goblin. Or a trickster, or a warrior. A nameless, terrible thing, soaked in the blood of a billion galaxies. The most feared being in all the cosmos. Nothing could stop it, or hold it, or reason with it – one day it would just drop out of the sky and tear down your world."
 * Want to make it awesomer? Give it to a former Doctor. And yes, Sylvester McCoy is actually reciting the same speech.
 * What makes the scene awesome for me? Here he is, about to intimidate the hell out of everyone, and how does he open his badass boast? By dropping the microphone to the loudspeaker! That is 100% pure Doctor!
 * Of course, amidst all this, it should probably bear mentioning that his timing for these is sometimes less than stellar. In addition to a couple mentioned earlier where he failed to make good on them, there's "The Lodger," where he hears somebody mention annihilating their enemies and immediately launches into one of his Oncoming Storm speeches about how he won't allow annihilation on his watch, only to belatedly realize they were talking about football.
 * Also from "The Pandorica Opens" the Doctor makes a completely unintentional Baddass Boast, unaware that the creature he's describing is himself (made all the better when you recall all the times he's boasted about the things that fear him):

"House: Fear me, Doctor. I've killed hundreds of Time Lords. The Doctor: Fear me. I've killed all of them."
 * From The Doctor's Wife:

"Madam Kovarian: The anger of a good man is not a problem. Good men have too many rules. The Doctor: Good men don't need rules. Today is not the day to find out why I have so many."
 * In the Series 6 episode "A Good Man Goes to War," Matt Smith's excellent delivery of the 11th Doctor's retort to the assumption that he is a good man and good men won't do anything bad when angry makes the statement far more threatening than it would be otherwise.

""When we are both in the Great Hereafter, I will hunt you down, Bent-Face! And put you through my agonies a thousand times!""
 * Leela has one in "The Sunmakers", when she's being held hostage to force the Doctor to do something. Someone tells her that she'll die if he doesn't come back. "Then I die." (Pulls out her knife.) "But before I do, I'll see this rat's nest knee deep in your blood. That is a promised thing." (One of the hostage takers says that if she has to be killed, he won't be the first on his feet.)
 * Leela gets another good one in The Talons Of Weng Chiang. She's about to be killed in a particularly painful manner by Magnus Greel (for the purpose of prolonging his life by a means that is rapidly losing effectiveness), and this only makes her angry:

"I cross the void beyond the mind The empty space that circles time I see where others stumble blind To seek a truth they'll never find Eternal wisdom is my guide I am the Doctor!
 * One from Jon Pertwee:

Through cosmic wastes the TARDIS flies To taste the secret source of life A presence science can't deny Exists, within, outside, behind The latitude of human minds I am the Doctor!"

"My voyage dissects the course of time "Who knows?" you say, but are you right? Who journeys deep to find the light That glows so darkly in the night? Toward that point I guide my flight

As fingers move to end mankind Metallic teeth begin to grind With sword of truth I turn and fight The satanic powers of the night

Is your faith before your mind?

Know me:

I Am...

The Doctor!"

"Owen: I'm wrong. Guard: What are you? Owen: I'm broken. Guard: What are you!? Owen: I'm Dr. Owen Harper. And I'm having one hell of a day. *smack*"
 * From the Doctor Who spin-off Torchwood,  Owen Harper faces off against a security guard and rolls off a particularly badass talk-down:

"Owen [talking to a child cancer patient] Jamie, you're scared, of course you are, the last lot of chemo didn't work and you can't bear the thought of going through all that pain again, I understand that mate, I really do. But let me tell you, that not everyone dies from this disease. And the ones with the best chance of making it are the ones who believe they can beat death. And sometimes, just sometimes, you can. So watch and learn, Jamie Burton. Child Watch what? Owen Watch me. Beat. Death."
 * Another Badass boast made by Owen in Dead man walking also doubles as an inspirational speech.

"The First: I'm not a demon, little girl, I am something you cannot even conceive. The first evil. Beyond sin. Beyond death. I am the thing the darkness fears. You'll never see me but I am everywhere. Every being. Every thought. Every drop of hate. Buffy: All right, I get it. You're evil. Do we have to chat about it all day?"
 * From The Wire, Badass Longcoat wearing gunslinger Omar Little, who has just taken out one assassin while injuring another: "'Ey yo, lesson here Bey. You come at the king, you best not miss."
 * Averted or something (subverted?) in Blakes Seven "Weapon": The eponymous Blake is a famous freedom fighter. He meets a man named Coser who says, full of hero-worship, "You're Blake! You're Blake!!" Blake says calmly, "Yes, I know who I am."
 * Subverted in "Amends," the episode of Buffy the Vampire Slayer where Buffy first meets the First Evil:

"Buffy: Looks good, doesn't it? They're trapped in here. Terrified, meat for the beast, and there's nothing they can do but wait. That's all they've been doing for days, waiting to be picked off, having nightmares about monsters that can't be killed. But I don't believe in that. I always find a way. I'm the thing that monsters have nightmares about. And right now, you and me are gonna show 'em why."
 * Later, Buffy gives one of these to the First's Turok-han champion. In a twist, the champion doesn't understand language and Buffy knows it. The real audience is the watching potentials, who need some inspiration:

"Buffy: I'm beyond tired. I'm beyond scared. I'm standing on the mouth of Hell and it is going to swallow me whole... and it'll choke on me. We're not ready? They're not ready! They think we're gonna wait for the end to come, like we always do. I'm done waiting. They want an apocalypse? Well, we'll give 'em one. Anyone else who wants to run, do it now, 'cause we just became an army. We just declared war. From now on, we won't just face our worst fears, we will seek them out. We will find them, and cut out their hearts, one by one, until the First shows itself for what it really is. And I'll kill it myself. There is only one thing on this earth more powerful than evil. And that's us. Any questions?"
 * This one is followed shortly by another speech to the Potentials, at the end of the episode:

"Angelus: No weapons. No friends. No hope. Strip all that away, and what's left? (swings his sword toward Buffy, intending to slice her in half) Buffy: (catching the sword in her hands) Me."
 * Buffy also gets a one-word Badass Boast toward the end of the second season finale:

"Demon: Who are you? Buffy I'm Buffy. The Vampire Slayer. And you are? (Cue Buffy single-handly bringing down the entire operation)"
 * Buffy also gets another one in the very next episode "Anne". Having fled Sunnydale, she's trying to abandon everything of her life as the Slayer, even to the point of going by her middle name, Anne. Then she gets tricked into falling into a hell dimension where demons are using humans kidnapped from Earth as slaves. To each slave, the slaver asks "Who are you?" then beats the captive until they reply "Nobody". The he reaches Buffy:

"ANDREW: I am bad. I'm bad, I'm evil, but I'm protected by powerful forces. Forces you can't even begin to imagine, little girl. If you harm me, you shall know the wrath of he that is darkness and terror. Your blood will boil, and you will know true suffering. Stand down, she-Witch. Your defeat is at hand. WILLOW: Shut your mouth. I am a she-witch, a very powerful she-witch... or witch, as is more accurate. I'm not to be trifled with.
 * And then there's the time Willow and Andrew tried to get into a Badass Boast duel...

ANDREW: But I...

WILLOW: I'm talking. Don't interrupt me, insignificant man. I am Willow. I am Death. If you dare defy me, I will call down my fury, exact fresh vengeance, and make your worst fears come true. (Brightly) 'Kay?"

"Buffy: Looks like a job for Wiccan girl. What do you say, Will? Big time danger. Willow: Hey, I eat danger for breakfast. Xander: But, oddly enough, she panics in the face of breakfast foods"
 * Most of the scene is played for humor, but Willow's last line is deadly serious. One season before, she could never have pulled it off.
 * In the Buffy the Vampire Slayer episode "Choices":

"Kitano: I honor he who would kill his god, and to his brethren of the Tau'ri: slayers of Ra, Hathor, Setesh, Heru'ur, Sokar, Cronus, and Apophis. O'Neill: Well, somebody's been keeping score."
 * In Stargate SG-1, She gets a good one in on her way out. "Make no mistake -- Osiris will return. And the rivers of the Earth will run red with blood."
 * There were a couple of occasions where the team had to remind themselves of their kill tally so far. This was nicely turned around in "The Warrior," where another character does it for them:

""Hey, I'm Dr. Rodney Mckay, all right? 'Difficult' takes a few seconds, 'impossible' a few minutes.""
 * Even more awesome when you consider Apophis should be listed more than once.
 * And in Stargate Atlantis, McKay lets off one in "Brain Storm"

"Tomalok: I give you 30 seconds to reconsider, Picard. Picard: I do not require one, Tomalok. ... If the cause is just and honorable, [the crew] are prepared to give their lives. Are you prepared to die today, Tomalok?"
 * Captain Jean-Luc Picard delivered such pithy badass boasts on Star Trek: The Next Generation. Consider this beauty from "The Defector", where a Romulan commander is trying to threaten Picard into surrendering:

"Duras: This is not your world, human. You do not command here. Picard: I'm not here to command. Duras: Then you must be ready to fight. Something Starfleet does not teach you. Picard: You may test that assumption at your convenience."
 * "We are the Borg. Lower your shields and surrender your ships. We will add your biological and technological distinctiveness to our own. Your culture will adapt to service us. Resistance is futile."
 * "Assimilate THIS!"
 * In "Sins of the Father":

"Odo: How did you get in here? Koloth: I am Koloth. Odo: That doesn't answer my question. Koloth: Yes. It. Does."
 * Keep in mind, this is AFTER Worf's brother has already been stabbed. Picard proves he's not just bluffing later in the episode by fighting off Duras' assassins.
 * And from Star Trek: Deep Space Nine we have Koloth's introduction, after sneaking into Odo's office.

"Odo: Doctor if a Klingon were to kill me, I'd expect nothing less than an entire Opera on the subject."
 * Odo gets his own in the episode The Way of the Warrior.

"Now, before anybody decides to get clever, you should know I have multiple deadman sensors from every culture on my ship and a few cultures I haven't heard of. My heart stops, we all go boom. My heart speeds up, it's boom again. Too hot, too cold, too happy, too sad, thirsty, hungry, bored -- it's John Lee Hooker time. Boom, boom, boom. And you try your little psychic trick -- kaboom! -- and we're all pushin' up day-glo daisies. Stark: "If you've got a deity you had better make your peace with it now, because I'm going to lead you to the other side real quick.""
 * Farscape had a few, particularly from John Crichton when he strolled into a Scarran base with a nuclear weapon clipped to his belt:

"Tommy Oliver: I may be old, but I can still pull it off. Dino Thunder, Power Up! *cue the Co-Dragons getting their asses handed to them*"
 * "I am Lord Zedd, emperor of all that is evil."
 * I am Lord Zedd, ruler of all that I see.
 * A later season gives us this gem from a returning veteran:

"Day shall become night as I escape the Netherworld to face my enemies!"
 * And then Master Xandred brings us this right before busting open a can of whoop-arse:

"Sarah Jane Smith: Listen to me, . I have fought the worst things from the darkest corners of the Universe. You don't stand a ghost of a chance."
 * Kai's speech from Lexx: "I've killed mothers with their babies. I've killed great politicians, proud young warriors, and revolutionaries. I've killed the evil, the good, the intelligent, the weak, and the beautiful. I have done this in the service of His Divine Shadow and his predecessors, and I have never once shown any mercy."
 * His Divine Shadow,  makes his own boast while the Lexx tries to escape: "Stupid humans. Your entire species is MINE!"
 * From The Sarah Jane Adventures:

"The Mountain King: That is your fear, not mine, Mab. I cannot die. I am the Rock of Ages; I will live forever, on the edge of dreams."
 * In the 1998 series Merlin, Mab attempts to convince the ancient Rock of Ages not to give Excalibur to Arthur, arguing that Arthur will destroy the Old Ways and the Rock of Ages will be forgotten. The voice of the Mountain King promptly sets her straight on why he isn't worried about this.

"Don't you know who I am!? My name is John Mitchell and I've killed more people than you've met!"
 * Russell Edgington in True Blood has one,
 * "And now, the weather. Tiffany?"
 * "Think long and hard. You've been bird-doggin' this township for a while now. They wouldn't mind a corpse of you. Now, you can luxuriate in a nice jail cell, but if your hand touches metal, I swear by my pretty floral bonnet, I will end you."
 * "No power in the 'Verse can stop me."
 * "Also? I can kill you with my brain."
 * "Now I did a job. I ain't got nothing but trouble since I did it, not to mention more than a few unkind words as regards to my character, so let me make this abundantly clear: I do the job. And then I get paid."
 * Crow tries. "Keep the money. Use it to buy a funeral. It doesn't matter where you go or how far you fly. I will hunt you down, and the last thing you see will be my blade." It doesn't work, since Mal just kicks him into the engine.
 * Mitchell from Being Human gets a few.

"Annie: There is a question you haven't asked yourself yet. If I exist what else does? You think you're the big bad wolf. You should see George on a full moon. You think you're a cold-blooded murderer? Mitchell was killing 80 years before you were even born. Don't you get it yet? I'm just the tip of the iceberg, I'm good cop. Look at you, so pleased with your grubby little murder. Fact is, when it comes to pure naked evil you're an amateur. I want you to know you wandered off the path. This is where the wild things are, and we have got your scent now. We can find you at the edge of the earth and create unimaginable tortures... and now I'm going to tell you the very worst thing in the world, something only the dead know... (leans forward to whisper into 's ear) Annie: I saw it. My advice to you; find a safe place with locks and bad dogs and never, ever turn out the light."
 * Annie gets one with reference to the whole trio:
 * Th-that's not true!

""I am the Brain Inter Active Construct. No matter my form, my intellect remains formidable. Do not underestimate me.""
 * From Smallville: "I am the villain of the story."
 * Also, from Major Zod in the Season 9 finale: "Unlike you I will lead from a throne, not from the shadows. Every human on earth, including the woman you love will Kneel Before Zod!"
 * Brainiac also gets one, although it helps to understand the context. Having been nearly destroyed by Clark in Season 5, it takes him until Season 7 to rebuild From a Single Cell. When Bizarro finds him halfway through Season 7, he is therefore weak, dying, barely holding himself together, and feeding off of people and animals in order to hold his Nanomachines in place. When he and Bizarro team up, he proposes that he be the one to kill Clark. Bizarro tells him: "You? You can barely catch a rat." Brainiac responds with the following short, but sweet boast:

"Sol: We're done. If you keep it up, we're going to fight, and you'll have to work by yourself while I convalesce."
 * Given the context, pretty Badass. He then proceeds to manipulate both Clark and Bizarro to his own ends, fully living up to the boast.
 * And then there's the Martian Manhunter: "I'm Mars' last survivor. There's a reason for that."
 * Hilariously averted in Deadwood, when Seth (accurately) calls Sol's current lover a whore.

"Claudia: "I imagine losing a child is the worst pain a person can go through." Helena: "No actually. When I tracked them down. What I did to the men who kill my daughter? That's the worst pain a person can go through.""
 * Warehouse 13 - Not so much a Badass Boast as a Creepy As Hell Statement Of Facts, but after Helena Wells has won massive Woobie-points explaining that her daughter was murdered in a random break-in that she was unable to stop:

"All those tattoos, all those new tricks you've learned...doesn't matter what you try. Doesn't matter where I am or how badass you think you've become. 'Cause you know what? I'm Angel. I beat the bad guys."
 * In Angel, the title character gives one to Lindsey:

"Hamilton: Let me say this as clearly as I can. You cannot beat me. I am a part of them. The Wolf, Ram, and Hart. Their strength flows through my veins. My blood is filled with their ancient power. Angel: *pops fangs* Can you pick out the one word there you probably shouldn't have said?"
 * Hamilton also gets one. It backfires a bit.

"Castiel: You should show me some respect. I dragged you out of hell, and I can throw you back in."
 * The angels in Supernatural get a few of these. Particularly Castiel in early S4.

"Zachariah: In Heaven I have six wings and four faces, one of which is a lion."
 * Also, Zachariah in 5.16.

"Lucifer: I will never lie to you; I will never trick you; you will say yes to me."
 * This troper got chills when the Trickster said: 'They call me Gabriel'. It's all in the delivery.
 * Not to be left out - Lucifer.

"Castiel: Maybe someday, but today, you're my little bitch."
 * Castiel again in the fifth season when facing Raphael.

"Castiel (paraphrased):"
 * Castiel yet again in the season 6 finale.

"Castiel: You're just a man. I'm an angel. Dean: I don't know. I've taken some pretty big fish."
 * Death gets several right from his introduction, just watch this clip
 * The humans get 'em too.

"Dean:All those angels, all those demons, all those sons of bitches, they just don't get it, do they Sammy? Sam:No, they don't, Dean. Dean: You see, Brady, we're the ones you should be afraid of."
 * Also, when Dean and Sam have trapped a demon whose influence was substantial in

"Santana: First of all, anything you do became my business when you decided to toss that slushie up in my grill. Karofsky: I think I can take a couple of queers and a girl. Santana: Ha. See here's what's gonna go down. 2 choices: you stay here and I crack one of your nuts - right or left that's your choice - or you walk away and live to be a douchebag another day. Oh, and also? I have razor blades hidden in my hair. Mm-hm. Tons, just all up in there."
 * Hank from Terriers gets one near the end of the pilot: "I'm gonna destroy you, Lindus. I coulda walked away from this thing an hour ago eating shit and Jesus knows I've eaten enough in my life. But you killed my friend. So I'm going to destroy you. And I just wanted you to know that."
 * It may not be nearly the same kind of show as the ones listed here, but Glee even manages to get one from Santana.

"Hardwicke: It's 5:17. Evening hours started at five o'clock. The guards are all outside with the population. There won't be anyone to open that door for at least thirteen minutes, and it took me less than five to do this. (Holds up the picture of his victim.) While you were doing your research, maybe a question or two about security tones would have been a good idea? Hotch: I heard the security tones. Hardwicke: So you planned to be locked inside with me with no guns or weapons? Hotch: I won't need a gun. Hardwicke: There's no way they're going to execute me next week. Not after I kill two FBI agents. You saved my life by coming here. Hotch: Unfortunately for you, I'm not a five-foot-tall, hundred pound girl. (takes off his jacket) All your life, you've gone after victims who couldn't fight back. And the rest of the time, you spent looking over your shoulder, worried about the knock on the door. (removes his tie) Scared that someone like me would be on the other side waiting to put you away. At your core, you're a coward!"
 * It is however seriously subverted when she tries it on wrestling champion Lauren Zizes who beats her down during the badass boast. Santana even continues the boast after being beaten.
 * I am Deker. Nothing more, nothing less.
 * One does not piss off Special Agents Rossi and Hotchner of Criminal Minds.
 * Rossi, from "Masterpiece: "You waited until I turned my back, didn't you Henry? Just like you did with those women. (Grace tries to punch him, Rossi slams him back on the wall.) Don't give me a reason to hurt you. Oh and one more thing, I'm gonna be there when they strap you down for that lethal injection. And just before they hit the plunger, I'm gonna lean real close and tell you to SAY HELLO TO YOUR SCUMBAG BROTHER!!"
 * Chester Hardwicke from "Damaged" gets one, but Hotch has an excellent comeback:

"Ser Jaime Lannister: There are no men like me. Only me."
 * Game of Thrones:

"Jory Cassel: If you threaten my lord again... Ser Jaime Lannister: "Threaten?" As in: "I'm going to open your lord from balls to brain and see what Starks are made of?""
 * Which is actually ironic considering that he's a twin, but I guess he didn't say there were no women like him.
 * Jaime is quite good at these in the books, and that is carried over into the TV series:

"Robb: Tell that winter is coming for him."
 * in The Pointy End Robb uses his family's Badass Creed as this:

"Syrio Forel: The First Sword of Braavos does not run"
 * From the same episode:

"Lysa: These men are knights of the Vale. Every one of them loved Jon Arryn. Every one of them would die for me. Tyrion: If any harm comes to me, my brother Jaime will see that they do."
 * And Tyrion delivers one on Jamie's behalf in The Wolf And The Lion:

"Tyrion: The Eyrie, seat of House Arryn. They say it's impregnable. Bronn: Give me ten good men and some climbing spikes. I'll impregnate the bitch."
 * Another excellent one from the same episode.

"Daenerys: I am a khaleesi of the Dothraki. I am the wife of the great Khal and I carry his son inside of me. The next time you raise a hand to me will be the last time you have hands!"
 * Dany finally standing up to her abusive brother in Cripples, Bastards and Broken Things:

"Daenerys: I am Daenerys Stormborn, of House Targaryen, of the blood of old Valyria. I am the dragon's daughter! And I swear to you, that those who would harm you will die screaming. Mirri Maz Duur: You will not hear me scream! Daenerys: I will! But it's not your screams I want. Only your life."
 * Another Dany one from the finale Fire and Blood:

"Daenerys: I am Daenerys Stormborn and I will take what is mine...with fire and blood."
 * From the trailers for the second season:

"Stannis: By right and birth and blood, I do this day lay claim to the Iron Throne of Westeros. Let all true men declare their loyalty. They shall bend a knee, or I will destroy them."
 * And another gem from the same source:

"Balon: No man gives me a crown. I pay the iron price. I will take my crown. That is who I am."
 * Balon Greyjoy gets one in his introductionary episode:

"Tyrion: Those are brave men knocking on our door. Let's go and kill them!"
 * Let's not forget how Tyrion clinches his Rousing Speech to the defenders of King's Landing during the Battle of Blackwater Bay:

"Stannis: Come with me and take this city!"
 * Stannis also gets a short sweet one during Blackwater, which becomes even more impressive when you remember he's not considered a charismatic commander:

"Chesney: "God helps those who help themselves." Ford: "And I help people who can't. And God help you if anything should happen to that boy, because if he spends more than one second longer in that hospital than he needs to, I will make it my mission in life to end you. I will ruin you. I will ruin your name, I will ruin your company. I will bring down everything you have ever touched. And when I am done, I will hunt you down, and I will kill you myself.""
 * Ford gets a nice one in the Leverage episode, The Cross My Heart Job:

"He eats guys like you for breakfast! And sometimes lunch... but mostly dinner."
 * From Reaper:

"Atia: (to Octavian) Marc Antony buggers boys like you for a morning snack."
 * Considering this was said by a demon talking to her human boyfriend about another demon, chances are she actually wasn't speaking metaphorically..
 * Variation appears on Rome.

""I'm not in danger, I am the danger!" "Do you know what would happen if I suddenly decided to stop going into work? A business big enough that it could be listed on the NASDAQ goes belly up." "I am the one who knocks!""
 * Grey's Anatomy: when Alex tries to hit on a pretty patient who doesn't speak English, her translator tells her that he's flirting with her and she sweetly replies "tell him that I eat little boys like him for breakfast." It's funny because she's a competitive eater.
 * Cougar Town: When Andy is told he has to stay in a hot car for one hour, he responds, "I'm Cuban. We eat heat for breakfast." He doesn't last five minutes.
 * Walter White of Breaking Bad is a boasting machine, and that gives way to a lot of memorable ones:

"I am the last dragonlord. And I am warning you, leave this egg alone."
 * Highlander Duncan gets one in the pilot. "'I am Duncan Macleod of the Clan Macleod and you are doomed."
 * Chuck, among many badass moments from the members of Team Bartowski, had this line from John Casey: "I'm a Casey. I don't run. I stalk my prey."
 * And perhaps even better, in the fourth season finale from Chuck himself after finding out, and shortly after hurling a chair at a monitor without flashing: "That guy may think he's a hardass. But I'm the Intersect." Theme music reprise blares, cue Title Screen.
 * In Merlin, while there are a lot of these, they are almost all subverted in some way.
 * From the pilot, Arthur tells Merlin that "I could take you apart with one blow." The subversion is that, even untrained, Merlin could easily take him.
 * Merlin's response "I could take you apart with less than that." is also a subversion, despite being true, because magic is outlawed in Camelot and doing so would cause his death.
 * In Episode 5 of Series 1, Arthur tells a candidate knight. "You face the most feared of all foes, the ultimate killing machine. You face me." This would be a pretty awesome Badass Boast, if it weren't in the episode named Lancelot.
 * The Sorcerer's Shadow features a double subversion from Uther before he fights against Arthur in a tournament. "I didn't inherit this kingdom, I won it. One day you will be strong enough to take my crown, but not yet." The first subversion is that Arthur could beat him, and has spent most of the episode beforehand worrying about it. The second is that
 * Merlin, however, plays the trope straight in "Aithusa".When on a quest to recover a dragon egg, Merlin finally makes it to the tomb and is fighting a would-be thief for it.

"Merlin: You won't find me such easy prey. Lamia: Your magic holds no fear for me. I could have killed you any time I wished. Merlin: Then what are you waiting for?"
 * This could be either a subversion or being played straight. When confronting Lamia after she sucks the life from two knights. He gets knocked into a wall right afterward,.
