One Bullet Left

""He's taken hostages. Bring him down with one shot!""

- The player character's assistant, Silent Scope EX

"In a man to man fight, the winner is he who has one more round in his magazine."

- Erwin Rommel

The hero has entered the enemy base. He has killed mooks, blown stuff up, and said one liners. This is it. The final showdown. Hero vs. Big Bad. Mr Villain says, "It's too late! The files have already been transferred!" as he holds the heroine close, threatening to kill the damsel in distress. She cries out to her beloved hero. The hero gathers his resolves and checks his pistol's magazine. He only has one bullet left.

Wait, what? One bullet left? Oh never mind, he's totally gonna kill the bad guy.

This trope is named after the uncanny attempt at drama of giving the hero only a single chance to win the battle, i.e. one bullet left. You can be sure of it, you can count on it, you could bet money on it if anyone would actually take that bet. That shot is going to hit its target. It may have been actually suspenseful at some point, but by now everyone has seen this one done and done again.

May happen during a Darkened Building Shootout.

Anime and Manga

 * Trigun: Vash has used up five of his six shots to make a giant projectile veer off course from a group of incapacitated civilians. Vash ejects the empty cartidges (even saying "Only one bullet left, doc."), spins the barrel, locks it without looking, and shoots - he picked the right chamber. Somewhat justified in that
 * Used epically in the Final Battle; both Vash and  end up with one bullet each in a random chamber of their respective revolvers, and.
 * Is a major part of the Go Shogun movie.
 * In Gun Blaze West during a gun duel, Viu deliberately empties his gun of all but a single bullet in the belief that because he only has one bullet, his focus will improve and make that one shot count more than the others. It does.
 * Train Heartnet in Black Cat has one Oricalcum bullet, and the only thing that can defeat Creed. He almost loses it when he drops it whilst falling, but catches it of course, and his aim is true.
 * Mobile Fighter G Gundam: During their fight with the Grand Gundam, Chibodee runs out of bullets in his Gundam's revolvers, and George is down to a single Attack Drone. He provides the distraction while Chibodee uses the Attack Drone as a bullet to make the million-to-one shot that takes out the Grand Gundam.
 * The Tachikoma in Ghost in The Shell are among the worlds best killing machines that can deal with anything short of a heavy tank without breaking a sweat. But when most of them are dismanteled and the rest of them had been refitted for civilian work, they had to rescue Batou from a special forces hit squad with nothing but a single ancient mortar round a senile old veteran had stashed in a shoe box as their only weapon. When they arrive at the scene, Batou had already killed most of the attackers, except for one last soldier in a huge suit of powered armor who was crushing him under his giant foot. After chasing him into the nearby forest while losing one of their own, the last two try everything they can to make their one single shot count. But as a subversion, with a weak "Pfshhh..." the propellant fizzles without ejecting the grenade, and the last two Tachikoma get immediately riddled with gaping bullet holes.
 * Subverted in Miyazaki's "Castle in The Sky". Deep in the floating city Pazu and Muska face each other down with guns raised. The observant, however, already knows both our hero's and the villain's guns are empty.
 * However, Muska has reloads.
 * In Gosick, Victorique, of all people, ends up with a single bullet left in a gun; though she needs it not to kill someone, but to . Halfway-subverted, though, because both she and Kujo have more than enough Genre Savvy to know that there's absolutely no chance of the shot missing. In fact, she may have wasted the rest of the bullets on purpose...

Film
"Farris: How many bullets do you have left?
 * The ends of both Die Hard and Die Hard With a Vengeance. At the end of the first movie, John McClane actually had two bullets left, and exactly two bad guys left to kill. Played with, in that  At the end of the third, he had two bullets left in a small gun, and two bad guys in a helicopter with a BFG. He
 * The end of the shootout/rescue scene near the start of Mission Impossible III. Of course, Hunt had been shooting excellently up into that point anyway, and wouldn't have checked his ammo if Ferris hadn't asked him how much he had left.

Ethan: Enough. *shoots the last goon* Now I'm out."

"Bad Guy: "Now how the hell did that happen?" * collapses*"
 * Clint Eastwood's Man With No Name does this at the end of A Fistful of Dollars. He has one bullet left in his six-shooter, while the bad guy has one bullet in a rifle. Clint might have been lucky, but considering how Badass the MWNN is, he was probably just that good.
 * The point was that both of them have one bullet, but they have to load their weapons of choice first. And Clint's six shooter is faster to load than the Big Bad's rifle. Or So I Heard.
 * Subverted in Top Gun, in which Maverick is sitting on one missile and facing 3 MIGs at the end of the climactic air battle... And then the MIGs retreat.
 * From the 2000 film The Patriot, Benjamin Martin deliberately saves a special bullet made from one of his murdered son's lead soldiers especially for the Big Bad who killed him, Colonel Tavington. Subverted in that while he does get his final, poetic justice-y shot in on Tavington, a cannonball landing nearby throws off his aim and only wounds the villain, leading to a rather fierce duel between Benjamin and the now very pissed-off Tavington in the midst of the battle.
 * In Independence Day, the trope becomes "One Missile Left". By the time the humans realise they need to attack the weakpoint of the alien ship in order to bring it down, the only guy left with the ability to exploit their new weakness is the insane crop-dusting veteran.
 * The pipe bombs in Tremors. Val kills the last Graboid with the last pipebomb, although he uses it in a slightly different way than expected.
 * Subverted in Tremors 2: the heroes are trying to reach the last working vehicle in the area and escape a Shrieker pack, only to find the route blocked by one of the creatures. Burt Gummer has only one (enormous) bullet left for his (equally-enormous) rifle. He successfully shoots the Shrieker, but the bullet then punches right through a stone wall, several barrels, and wipes out the escape-vehicle's engine.
 * The Host,
 * Shanghai Noon has this in probable Homage to A Fistful of Dollars.

"Harry Callahan: Ah-ah. Now, I know what you're thinkin'. Did he fire six shots or only five? Well, to tell you the truth, in all this excitement, I kinda lost track myself. But bein' as this is a .44 Magnum, the most powerful handgun in the world, and would blow your head clean off, you've got to ask yourself one question: "Do I feel lucky?" Well, do ya, punk?"
 * By the way,
 * The climax in Dirty Harry. Apparently the Scorpio Killer did feel lucky, that punk....

"Bond: My six bullets against your one?
 * At the end of the western Bad Girls Kid Jarrett is apparently out of ammo, so Cody pops one bullet out of her gun and gives it to him, saying "Pick it up, put it in, die like a man."
 * In Freejack: Descending in an elevator to escape the building, the hero and his girl knows they will face guards on the way out. He looks at his LED ammo counter, sees it read "01", and remarks, "Think I can get them all to stand in a line?". Cut to a scene of the Mooks all lining up. But, at the last second, the elevator is called to the Big Bad's penthouse.
 * A different take on this is shown in Sky Captain and The World of Tomorrow (2004), where
 * In Pirates of the Caribbean, Captain Jack Sparrow spends the entire (first) movie and most of his backstory waiting to fire his single shot. (Granted, all guns were single-shot in that period, but he only carries one, without extra ammunition.)
 * Somewhat justified in that the bullet was a very special bullet; it was the exact same bullet Barbossa left him with to off himself when marooned.
 * Chow Yun-Fat embodies this trope in The Replacement Killers when, at the end of a Hong Kong-style gunfight, he comes face-to-face with his former employer and slaps his last clip in which has just One Bullet Left -- the dragon-marked bullet that he promptly uses to end him.
 * Another Chow Yun-Fat movie, The Killer, has hitman Ah Jong living by these words: "I always save the last bullet, either for myself or for my enemy." The first time he says this, it's when he's demanding of his handler Sidney to know who took out the Contract On the Hitman, and after a shootout in his apartment where Ah Jong defends himself and Sidney, it's revealed that he indeed had one more bullet. Unfortunately,.
 * Double Subverted in Wild Wild West: Artemis Gordon has a derringer with only one shot and only one chance to make an impossible shot to save Jim West's life. He fires, and misses. The villain delays killing West to mock Artemis for his failure, especially after the 'can I kill someone?' soul-searching he engaged in beforehand. Unfortunately, for the villain, Artemis wasn't aiming directly at him.
 * In both versions of The Flight of the Phoenix, they have 5 cartridges to start the rebuilt plane's engine - the first three times it stalls, the fourth cartridge is expended to clean out the cylinders, and the last one also fails, making the whole rebuilding project a waste of time and dooming them to die of dehydration after all shockingly enough, works perfectly.
 * A different take on this trope is in 8mm when the hero, whose gun has been unloaded and left on a table, only has time to load a single round in the chamber. And he's facing two criminals. While handcuffed to a desk.
 * In The Quick and The Dead, Russell Crowe's character, preacher and ex-outlaw Cort, is always given only one bullet before each gunfight... so he won't try to shoot his way out of town and escape.
 * Rango
 * Okay, fine. One plus two plus one... Shut up! The point is, there is ONE BULLET LEFT in this gun and guess who's gonna get it!
 * Valentin Zukovsky in The World Is Not Enough has precisely one bullet in his walking-cane gun, and has to decide between killing Electra and freeing Bond..
 * The Man With the Golden Gun. Happens with the final confrontation between Bond and Scaramanga; the latter only has a single-shot weapon, and Nick Nack taunts Bond with the fact that "You have only three bullets left" at one point.

Scaramanga: I only need one."

"Tintin: The bad news is, I've only got one bullet.
 * The Adventures of Tintin would not be complete as the Troperiffic romp that it is without this. It's invoked in a rather cool manner, too:

Capt. Haddock: What's the good news?!

Tintin: I've got one bullet. *shoots down plane*"

Literature

 * The Hobbit: Bard shoots the dragon with the only arrow he has left. Although more justified in this case, as the one left is also a special one inherited through generations, and just before the shot Bard is told the dragon's weak spot.
 * In the novel The Rescuers by Margery Sharp, Bernard (a mouse) attempts to stop the human villain from climbing a ladder. Having failed with a sword and an axe, he throws the last weapon in his arsenal, a tiny dagger. The sharp sting of the knife causes the villain to lose his grip on the ladder and come crashing to the ground.
 * Subverted in The Lost World, where a character is told that she only has One Bullet Left. After she makes the impossible shot, she checks the rifle and finds that there are still more bullets- she was told there was one left to motivate her.
 * Discworld plays with this, with the characters being Genre Savvy and arguing about how a "one in a million shot" always works. So they get rid of all their extra arrows, and set up an increasingly convoluted way to fire the arrow to make sure that the odds of success are exactly one in a million.

Live Action TV

 * Subverted in Lost, "Tabula Rasa," when many of the Losties think the marshal should be euthanized. Sawyer remarks on the appropriateness of there being one bullet left in the gun. Unfortunately, Sawyer shoots the marshal in the chest, which doesn't kill him and makes his suffering worse.
 * Also from Lost, when Sawyer, Michael and Jin are captured by the Tailies, Sawyer's gun had a single bullet left over from the shark incident. Turns out to be very important several episodes later
 * At the end of the episode "Revelations" of Criminal Minds, Reid pulls this trope off with a revolver. (It's thematic, and also lampshaded.)
 * Taken Up to Eleven in Supernatural, with two full seasons of buildup. The heroes are hunting "the yellow-eyed demon" armed with six blessed bullets. By the time they catch up to the demon with the gun, they're down to one..
 * Interesting example from Breaking Bad: Hank Schraeder has been cornered by one of Tuco's Cousins. He's about to kill Hank, who's out of ammo, with his gun, but then decides that would be too easy. Since Hank's otherwise immobilized, he calmly walks to where he left his chrome fire axe. Hank discovers that a bullet has fallen out of the Cousin's pocket (a free sample from the arms dealer, earlier in the episode), just out of arm's reach. Nonetheless, he loads his gun with it and kills the Cousin with a headshot, just as he's about to bring the axe down.

Music
"Well, I checked the chambers of my gun
 * Subverted in Nick Cave's "O'Malley's Bar", after the narrator has slaughtered everyone in the bar and the police are waiting for him outside.

Saw I had one final bullet left

My hand, it looked almost human

As I raised it bravely to my head

''"Drop your weapon and come on out!

Keep your hands above your head!"''

I had one long hard think about dying

And did exactly what they said."

Tabletop Games

 * Big Eyes Small Mouth has this as one of the Gun Bunny abilities. It's based off of the "Dramatic Ammunition Rules", which say you have infinite ammo until the GM decides it would be dramatically appropriate for you to be out; One Bullet Left, obviously, gives you one last shot after that.
 * In the Pulp Role Playing Game Spirit of the Century, Ammo normally isn't tracked; the game just assumes you brought enough and lets you get on with the fun. But if you bought a certain ability, you can declare at any time that you have one bullet left- you'll be out of ammo after your next shot, but that last bullet gets huge bonuses.
 * The Death Or Glory rule in Warhammer 40,000 can be invoked when a unit is being run down by a tank. Instead of getting out of the way with the rest of his unit, one soldier may stand directly in the vehicle's path and make a single shot with a ranged weapon or a single attack with a melee weapon. If he immobilizes or destroys the tank, he lives, otherwise he gets run over and dies messily. The dramatic potential for having an Imperial Guardsman about to be run over by a Chaos Land Raider, and then lobbing a melta-bomb through an open gun slit is limitless. As is the sheer awesomeness of having a Space Marine power-fist a tank about to run him over.
 * Starblazer Adventures, based on the 1980's British science fiction Comic Book. A character with the One Shot Left stunt may declare at any time that their ranged weapon only has one shot left. This gives their next shot a +3 bonus.

Video Games

 * The Silent Scope series always does this at the end, forcing the player into a situation, such as shooting out a pane of bulletproof glass, where he must waste all but the last bullet of his existing magazine (or, if there's only one or two bullets left already, the last bullet of his next magazine) before confronting the last boss. As such, you have to get a headshot on him, or it's game over with the bad ending.
 * Exception: Silent Scope 2 forces this situation after the last boss is killed. Your last target is the handcuffs that connect him to the Distressed Damsel.
 * In Silent Scope EX, the first two bosses are like this; failure to headshot will yield a big Life Meter penalty and you'll be forced to repeat the mission.
 * Call of Duty: World At War has a variant of this - the "Desparado" challenge has you kill an enemy with your magazine's last bullet.
 * Call of Duty Black Ops has one mission begin with you in a room full of mooks with one round left in your revolver.
 * Call of Duty Black Ops also features a multiplayer mode that has every player with a pistol (M1911 or PM), one bullet and ability to take one more bullet from a killed enemy. Missed the enemy? Your only hope now is a knife kill
 * In Syphon Filter: The Omega Strain's first bonus mission, Stone has a sniper rifle with only one bullet, and must kill enemies by snapping their necks until he finds the target.
 * Ghost Squad has a variant of this for the boss of mission 2: You get only one shot to headshot him, but that's because if you miss, he'll set off a grenade, not because it's your last bullet.
 * In Call of Juarez at the end, the bad guy takes you out with a gun shot to the head,
 * Starcraft II uses this with some subtlety. Raynor always carries his pistol around, but never uses it. It's not until later in the game when he  does he check his pistol and we see it loaded with only a single cartridge in the six-chamber cylinder. He simply clicks the cylinder back in place and holsters the gun back..
 * In the beginning of the game, it actually has two bullets in it. Raynor uses one of the bullets to shoot a TV that has Mengsk on it.
 * Point Blank does these with its infamous "sniping" challenges, where the player is given one shot to take down a small, moving target, such as a falling leaf or a tossed coin.
 * Counter-Strike: Source has the achievement "Magic Bullet" which involves killing an enemy with the last bullet you have loaded..
 * The achievement points out that this has to be a non-sniper weapon.
 * World of Tanks awards players a medal for destroying the last enemy vehicle in the battle with their last shell.
 * I Am Alive features this situation a lot - bullets are extremely rare. The protagonist starts out with a gun with no bullets and has to bluff people attacking him into backing off often with his empty gun - or threaten two or more people with a gun that has only a single bullet.

Western Animation

 * Subverted in an episode of Hey Arnold where a bulldozer is heading straight for a tree with a tree house the kids are in, they throw everything in the house including the sink (seriously) in it's path but nothing stops it. Arnold grabs a coffee mug and throws it hoping to hit the brake lever. It misses by a good deal.
 * Rabbit Fire -- a Bugs Bunny cartoon -- had a scene where Elmer Fudd seemed to have run out of bullets, much to Bugs and Daffy's amusement. ("Hey, laughing boy, no more buwwets!") Then Daffy grabs the gun and looks down the barrel... "Bang!" He had "one buwwet weft!"
 * One buwwet weft? Hey laughing boy! There was one-
 * I KNOW, I KNOW!!!
 * Mighty Max -- In The Maxnificent Seven, one of the four heroes who goes with Max, Virgil and Norman to the center of the earth to destroy Skullmaster's Crystal of Souls is Native American warrior and master archer Yona-Ya-Yin. He winds up having only one arrow left, which he uses to save the lives of Max, Virgil and Norman
 * In American Dad while Steve, his friends, and Principal Lewis are fleeing the casino. They hide behind a trash can until the goons empty their weapons. Barry (who's gifted at counting) claims they're out of ammunition which Lewis bursts out only to be shot in the shoulder by the last bullet. Barry lied and pointed out Lewis should never touch a fat boy's candy while sticking his finger in the bullet wound.
 * Played straight in the Code Lyoko episode Marabounta. When Jeremie's multi-agent system tries to destroy Aelita, Jeremie creates a virus to destroy it and uploads it into one of Odd's lazer arrows. He then has one chance to shoot the original agent and destroy the whole system. It then explodes.
 * In Mulan when Mulan uses the last rocket to shoot at the leader of the Mongols only to miss. 'He was five feet in front of you!'. She was in fact aiming for the snowpack behind the Mongols in an attempt at starting an avalanche. It works.
 * Double Subversion in the Young Justice episode "Homefront". Artemis is the last remaining member of the team standing, has one arrow left in her quiver, and needs to make a million-to-one shot. She takes the shot, misses, and runs away to come up with a new plan. Inevitably, when she's ready to try the new plan she's only found one replacement arrow, giving her one shot. It works.
