Ellen Ripley exterminating a tremendously large hive of Xenomorphs, including its queen, all by herself (give or take Bishop's escape vessel and the forklift suit) in Aliens
Actually, wait a minute, scratch that, the forklift suit only made it even MORE bad-arse
Obi-Wan and Anakin engaging in a volcanic-lava-drenched lightsaber duel to the death on Planet Mustafar in Star Wars Episode III: Revenge Of The Sith
Even if you do happen to understand that the film itself is objectively average at best, there's no denying that this scene in particular (as stupidly over-the-top and melodramatic as it may be) is an absolute crowning achievement of the franchise (unfortunately ruined by Anakin's easily facepalm-worthy "NO" scream just a few minutes later after being turned into Darth Vader)
Beatrix Kiddo fighting an entire Japanese opera house full of elite-class ninja assassins, including their queen, and coming out as the last person standing in Kill Bill Volume One
"I, too, like to live dangerously" - Austin Powers
(also, the later scene in Volume Two where she busts herself out of her own fake coffin almost tops even THIS)
Jack Black and Kyle Gass engaging in a rock-and-roll battle against Satan himself and winning in The Pick Of Destiny
I know every lyric from the rock-off. I can't tell if I should feel proud or ashamed for that.
So THAT'S why Jack calls his band "Tenacious"
Agent J fighting humongous and terrifying man-eating space aliens (Edgar in the first movie; Boris in the third) head-on with little more than his own bare hands and easily winning both times in the Men In Black trilogy
To be quite honest, Agent J is by FAR the better agent between him and K in every possible way
(also has the better actor, although that might not have exactly been the fairest of comparisons to be making at the first MIB's time)
Gandalf screaming "YOU SHALL NOT PASS" at the top of his lungs, then shattering the entire Bridge Of Khazad-Dum into pieces in one clean hit with his staff and engaging in a free-falling duel to the death with Balrog in the Lord Of The Rings trilogy
Now HERE is a moment in which these films actually DID somewhat live up to their hype
Thanos completely wrecking the Incredible Hulk himself in a hand-to-hand fight without even trying (as part of the film's opening sequence, no less) in Avengers: Infinity War
And yes, just in case you were wondering, it was also completely WITHOUT Thanos actually using his Infinity Stone powers as well (not to imply that I actually do find the movie all that good overall, because I really don't, but hot DAMN is this scene awesome)
V self-demonstrating to Mr. Creedy and his henchmen that "ideas are bulletproof" in V For Vendetta
Let me just say right now that he died for a truly noble cause (Phantom of the Opera, eat your heart out)
Jules theatrically and ominously reciting the Ezekiel 25:17 verse from the Bible as a dramatic prelude to him and Vincent brutally gunning Brett down in Pulp Fiction
"The PATH of the righteous man is BESET on all sides by the inequities of the selfish, and the tyranny of evil men. BLESSED is he who, in the NAME of charity and good will, shepherds the WEAK through the valley of darkness, for he is TRULY his brother's keeper, and the FINDER of lost children. And I will STRIKE down upon the with GREAT vengeance and FURIOUS anger, THOSE who attempt to POISON and DESTROY my brothers...and YOU will KNOW(! ) my name is the LORD(! ) when I lay my VENGEANCE upon the! "
WAY more than enough said
"What does Marcellus Wallace look like?! "
"He's black! "
"Go on! "
"He's bald! "
"Does he look like a bitch?! "
"Does he look LIKE A BITCH?! "
Prince Leonidas screaming "THIS IS SPARTA" at the top of his lungs and then kicking the Persian Messenger into his Spartan Pit Of Death in hyper-dramatized slow-motion in 300
Trash scene and trash dialogue. Good meme.
This is not Sparta, This is America.
Gave birth to one of THE most obnoxiously overused memes on the Internet but is still well worth mentioning
Iron Man taking an entire moon right to the face and casually shrugging it off in Avengers: Infinity War
The Joker blowing up an entire hospital and casually walking away from it as if it were nothing in The Dark Knight
The Joker burning an entire mountain of money right in front of his own gang's faces just to show how little he cares about it in The Dark Knight
"Some men just want to watch the world burn"
When the Joker stands right in front of Batman's incoming Bat Cycle just to see if he actually will run him over in The Dark Knight
Thor extensively cooking himself in a massive laser beam of concentrated solar energy and still living to tell the tale in Avengers: Infinity War
The T-1000 nearly managing to actually kill the T-800 in Terminator 2
Cartman discovering his lightning superpowers in South Park: Bigger, Longer And Uncut
The Grinch lifting an entire Christmas sleigh loaded with all of the gifts in Who-ville all by himself in How The Grinch Stole Christmas
Can you please do a version of this list for animated shows (including anime)?
Because the Magical Girl Lyrical Nanoha and Symphogear franchises have lots of those sorts of moments.
Sarah Connor killing the T-800 in The Terminator
Neo being able to reflexively dodge speeding bullets and even freeze them in midair in The Matrix
Neo taking on an entire army of Agent Smith clones by himself in The Matrix
When Darth Vader is clearly taking it easy on Luke and still completely destroys him in their iconic lightsaber duel from Star Wars Episode V
Spider-Man fighting Doctor Octopus on top of a moving train in Spider-Man 2
Rocky Balboa defeating the legendary Ivan Drago in Rocky IV
Dutch defeating the titular Predator all by himself in The Predator
