Captain America: The First Avenger/Awesome

Steve punching through a submarine dome has got to be one. Plus the fact that he caught the sub by swimming after it.
During boot camp, when Phillips tosses the fake grenade at the trainees as a Secret Test of Character, Rogers doesn't even flinch. He doesn't just jump onto the grenade, he curls up into a ball around it to minimize any damage it might have caused. This skinny, frail kid was fully prepared to perform a Heroic Sacrifice without a second thought (compared to the Jerk Jock who cowers behind a truck), and at the same time vindicates Erskine's faith in him.
- He's still skinny.
Also, Steve, when he is neither the Cap yet nor even recruited yet, stands up to the jerk at the theater, and is being brutally beaten, and still attempts to stand up to him, stating that he "can do this all day" when the jerk admonishes him for not giving up. Then Bucky manages to stop the fighting, and then counters the jerk and sends him packing when the latter tries to take a swing at him.
Also from pre-Serum Steve, his Cutting the Knot moment with the flagpole.
Cap being modest, yet somehow cocky at the same time.

Red Skull: What makes you so special?
Captain America: Nothing. I'm just a kid from Brooklyn.

- The point of this is to undermine Red Skull's Nietzsche Wannabe belief that to become an Ubermensch from the serum when Red Skull himself had not, there must be something special about Steve.
Pretty much any moment where Cap is acting as a One-Man Army, punching his way through hordes of Nazis and HYDRA agents, not to mention that entire Montage of him and the Howling Commandos systematically dismantling every HYDRA weapon and base they come across.
- Highlights of the Montage include Cap, without any warning, throwing his shield at a HYDRA sniper hidden in a tree. Also, Cap pulling a HYDRA soldier out of a three story tank with one hand, and throwing in a bandoleer of explosives with the other.
  - This troper thinks the final shot of Cap jumping from the exploding tank in slow-motion puts an appropriately badass end to that montage.
Steve yelling for them to keep going with the procedure despite the tremendous pain. "NO, don't! I can do this!"
- And right afterwards, Rogers' chamber opens up and with the theme music playing, it is revealed that because of his kind of courage and fortitude demonstrated when it was needed most, the treatment worked perfectly, turning the sickly loser into the ultimate man mountain.
- Keep in mind that, given how much taller Steve ends up, he was essentially being rack-tortured when he told them to keep going.
  - Also, Steve doesn't start screaming until the Vita-Rays are at seventy percent.
- Although it's overshadowed by Steve's courage, Erskine and Stark jumping to stop the procedure when Steve starts screaming in pain stands in sharp contrast to Schmidt's reckless disregard for not only his safety but Zola's as well when testing the tesseract.
Cap chasing down the Nazi spy right after being treated with the serum. Barefoot. Armed with nothing but his just enhanced body raised to the maximum human potential, his Determinator status and his wits.
Am I the only one who loved that his response to whether or not he wants to kill Nazis, ("I don't want to kill anyone. I don't like bullies, I don't care where they're from.") to not just be an awesome and believable one for a hero like him, but just awesome that they summed up Cap's entire character in two sentences?
- Nope. It's perfect. Good writing, good characterisation. Props also to the writers for averting All Germans Are Nazis in the second scene with Erskine and Cap before the procedure, too.

Erskine: Many people forget that the first country the Nazis invaded was their own.

There is when Steve Rogers is presumed lost and Col. Philips is about to lower the boom on Peg Carter for allowing this. Just then, Rogers returns to base, with 400 men, confiscated secret HYDRA weapons and invaluable intelligence that he rescued by himself. At that point, the soldiers, who were jeering Rogers on stage, now cheer him as he shows that he is more than a stage clown, more than a soldier, he is truly Captain America!
- After all that Cap gives himself up to Gen. Phillips for going on the mission without permission. Lawful Good indeed.
The moment Jacques slips underneath a HYDRA vehicle, attaches a bomb and lets it roll over him unscathed like it's no big deal.
The kid that the Nazi spy uses as a Human Shield gets one. It looks like Cap is going to have to choose between rescuing the child after he gets thrown into the river or chasing after the Nazi when the kid yells "Go get him! I can swim!"
This exchange:

Red Skull: "In my future there are no flags!"
Cap: "Not my future!"

Although she's just a little overshadowed by the title character, Peg Carter gets one or two great moments. One of the more noticeable ones is her putting a bullet through the skull of a driver at least one block away.
- In her introductory scene, Peggy puts a rude and boorish soldier (who had been mocking Peggy for her British background) in his place by knocking the soldier on his ass.
- In the "grenade" scene, she also runs toward it (and Steve).
- In the climax, Peggy saves (a shield-less) Cap from a flamethrower-wielding HYDRA mook by gunning the enemy down.
In their first meeting, Red Skull No Sells one of Cap's punches before punching Cap's shield and denting it.
- It should be mentioned that this is the prop shield that was part of his stage costume, not the Mighty Shield. Still, being able to bend metal with a punch is pretty badass.
  - Also a pretty awesome moment for Cap, holding the shield steady enough that the Red Skull puts a fist-shaped indention into the top of the shield. Normally, hitting the top of a shield with that kind of force would just cause it to slam into the other person's face, but not the Captain.
Captain America figuring out SHIELD's ruse with the fake hospital.
Let's just say practically everything involving Col. Phillips.

"Let's go find two more!"

- That line has gotta be his crowner, though.
It is a measure of Cap's total awesomeness quotient that Nicholas freakin' Fury is deferential to him.
How about Steve clinging onto the fuselage of a mini-bomber as it drops out of the flying wing, prying the canopy open, forcing the pilot to eject, taking his place and piloting it back into the flying wing? Captain America (comics), ladies and gentlemen, who missed class the day they taught what "impossible odds" meant in basic training.
- Captain America miss a class, not likely. He just ignored it.
A moment for the Skull that cements his status as Magnificent Bastard, as well as being no fool at all. During Captain America's rescue mission, when the Skull spots Cap fighting his way in on a security monitor, he immediately (and without otherwise reacting) starts arming and activating the base's self-destruct mechanisms, noting to Arnim Zola that their troopers are obviously outmatched, and thus the smart tactical maneuver is to get out when the getting is good.
Right before Steve jumps out of the airplane to rescue the hostages from the HYDRA base, he has this exchange with Peggy.

Peggy: You can't give me orders!
Steve: The hell I can't. [smiles] I'm a captain.

The entire interrogation sequence between Col. Phillips and Zola, from where Phillips nonchalantly starts eating a delicious steak dinner in front of Zola to make him uncomfortable, and then reveals that he had sent a coded Allied message telling his superiors that Zola had defected. Of course, he tells Zola that he should have nothing to worry about since the message was encrypted, unless HYDRA had already managed to break their encryption codes.
All great villians eventually kill an incompetent henchman, but Red Skull uses instant Fridge Logic on a HYDRA agent reporting a lost battle from which he escaped:

HYDRA Soldier: We fought to the last man.
Red Skull: Evidently not. (Kills him)

"You start running, they'll never let you stop. You stand up, push back."
An early one for Schmidt comes in the very first scene, when a trio of HYDRA mooks are struggling to no avail to push the lid off a sarcophagus that they think holds the Tesseract - and then Schmidt walks in and shoves it off by himself with minimal effort. It may not be much compared to what happens later in the movie, but it nicely illustrates right off the bat that our Big Bad is no ordinary Nazi.
In addition to all his magnificence and monstrousness, Red Skull has quite possibly the most awesome demise of all the Marvel Cinematic Universe villains, disintigrated in a blinding flash of light and blasted skyward, up through the ceiling of the Valkyrie and out into the vast reaches of the cosmos.
- Unless you watched Thor and recognized that as Bifrost teleportation..
The "Star Spangled Man" song. That's all.
- It's uncanny how the song sounds like it fits right in as a propaganda song for the WWII era. Plus, it's proof that once again, Alan Menken is an awesome, awesome composer.
- In the same sequence, Steve wears a cheaply made version of the classic Cap costume... and aside from the cheesy mask he looks exactly like Cap from the comics, physique and all. It's sure to make a fanboy smile.
Heinz Kruger is pretty awesome. He sneaks into a top secret project he knew about less than a day in advance, causes a distraction by detonating explosives disguised as a cigarette case and detonating it with a remote disguised as a zeppo, kills Erskine, steals the last remaining sample of the serum and takes off, not slowing down even when Peggy shoots him. He's an evil Nazi spy, sure, but you've got to admire his dedication .
The POWs, who include future members of the Howling Commandos, get one. They charge unarmed at men with machine guns and disintegrator weapons until they gain a foothold. Highlights include Dugan knocking someone the fuck out with a running punch.
