Emperor Nero: Let him die!
Two characters meet to do battle on the field of honor, watched by someone in a position of authority over them. Maybe they are gladiators, fighting for the amusement of the King and his people. Maybe they are two students fighting for the right to learn from a master. In any case, they fight tooth and nail to defeat each other, and eventually one comes out on top, tasting victory while the opponent lies helpless and defeated.
As he enjoys his hard fought victory, he is congratulated by the onlooker, who then coldly orders him to finish the job and finish off his opponent, killing them and taking the rightful place as the most brutal and powerful fighter in the land.
If the winner is The Hero (especially if he is an All-Loving Hero), he will more often than not refuse to kill his opponent, and attempt to leave without any more blood on his hands, thus earning the ire of the onlooker (unless it was a Secret Test of Character all along). If the heroic fighter is more aggressive, he may instead kill the captive to establish his character as being more inclined to brutality, to the amusement and satisfaction of the onlooker (who may not know that he is next).
Related to Coup de Grâce and Mercy Kill, where a character does this of their own free will, instead of being ordered to. Compare Kick Them While They Are Down, Get It Over With. Contrast Shoot Your Mate, Kill Him Already!.

- Near the end of the "Superman in Exile" storyline, Superman is forced to fight in gladiatorial games on the distant planet known as Warworld. After a hard-fought battle against the champion, Superman comes out victorious, and is ordered to Finish Him by the Big Bad Warlord Mongul, who is watching the fight. When Supes refuses, it angers Mongul, demoralizes and humiliates the champion (who had hoped for an honorable death in battle), and astonishes the hordes of spectators watching the fight. This part of the storyline was adapted into a Justice League episode titled "War World".
- Simon Dark: Gaius Publius refused when ordered to kill a fellow gladiator he'd defeated, which resulted in Caligula giving Gaius to his sorcerer as punishment turning Gaius into a monstrous nigh-immortal familiar, who retains his human sense of justice.

- Spartacus features what may be the Ur-Example in modern film, with Spartacus and the "Nubian" forced to fight to the death at the gladiator school (in violation of school policy that they would not be forced to kill one another while there) for the amusement of several Roman nobles. In a bit of an aversion, Spartacus, the titular hero, actually loses and his opponent is the one who refuses to carry out the killing blow, opting instead to throw his trident at the evil Roman politician who gave the order and then climb the wall of the arena to get at him. The incident (along with Spartacus's love interest being taken away from him) is what kicks off the riot at the gladiator training facility and starts the slave revolt that forms the main plot.

- As well as Flash's mercy wins over Vultan and Barin.
- Mad Max: Beyond Thunderdome (1985). Max refuses to kill Blaster after knocking off his helmet and finding the hulking brute is actually a drooling idiot. This violates the rules of the Thunderdome, in which two men with a quarrel enter and only one leaves (designed to stop quarrels from spreading and involving others). Worse, he blurts out the fact that Aunty Entity hired him to kill Blaster, forcing The Dragon to take direct action and kill Blaster himself. Entity gets her revenge by banishing Max into the desert.
- TRON: As Crom struggles to climb back up onto a ring platform, Sark tells Flynn to "finish the game".

- The Quick and the Dead is about a Quick Draw contest, but halfway through the movie Herod changes the rules so it's a Duel to the Death. After one of the contestants, Eugene Dred, rapes an underage girl, he gets into a gunfight with Lady. He loses and ends up on the ground pleading for mercy, then begs the Big Bad for help when he appears on the porch. Instead Herod insists Lady inflict the Coup de Grâce as per the rules. Lady heads back into the saloon instead, where Dred stupidly tries to kill her again, removing the moral ambiguity.

It takes their captain to get them shooting again to finish the job, with him hysterically screaming "Keep firing, you fools! Keep firing! Did I tell you to stop?! Finish it! Finish it!"
- Tarzan and the City of Gold: Tarzan is in Trial by Combat with Phobeg, The Strongman of the titular city. Lord Greystoke wins, of course, and literally throws his opponent out of the arena. The bloodthirsty crowd throws Phobeg back, and Queen Nemone doesn't bother with niceties; she demands Tarzan kill him. The Lord of the Jungle's reply is classic:
Tarzan: Why should I kill him? He cannot harm me, and I kill only in self-defense or for food... Tarzan kills only whom it pleases him to kill. I shall not kill Phobeg.

- Little House on the Prairie: "For the Love of Blanche," from the final season.

When Blanche is revealed to be alive later, Mrs. Oleson orders the sheriff back to make sure that Blanche is dead this time.

- Firefly In the episode "Shindig", Mal ends up in a sword duel with a local aristocrat. Predicably (since, well, one of these guys is a main character and one of these guys is not), Mal wins, with the aristocrat lying wounded on the ground.

- Averted, subverted, and played horrifically straight in the various seasons of Spartacus: Blood and Sand
- Subverted in Spartacus: Gods of the Arena. The first episode has Batiatus commanding Gannicus not to kill his opponent until the magistrate arrives to witness the games. Gannicus apparently can't hear Batiatus over the crowd, and finishes his opponent moments before the magistrate arrives.
- Averted in Blood and Sand, when Spartacus first fights Crixus in the arena. Defeated, he gives the missio, a symbol of defeat and a plea to the editor of the games to allow him to live. The whole episode leads up to that moment, establishing that Spartacus is too proud to beg for his life, but realizes he must if he is to survive to be reunited with his wife.
- Played heartrendingly straight in the episode Party Favors, when Spartacus and Varro fight an exhibition match for a boy's coming-of-age party. The boy in question orders the defeated Varro killed. Spartacus must follow through with the deed or they will both die, and no one will be left to look after Varro's wife and child.
- The climax of season 2 of Ripper Street has Reid screaming at a boxing match for Drake to kill Shine. That's literally kill him.

The season ends at that point, but we can expect season three to begin with Reid having an enormous My God, What Have I Done? moment.
- Game of Thrones.
- In "The Dance of Dragons", a Braavosi swordsman gets Ser Jorah Mormont on his back in the arena and looks to Queen Daenerys, clearly expecting this trope. Daenerys just stares in shock, not wanting Jorah dead yet unwilling to stop events. At the urging of the crowd, he decides to finish Jorah anyway, only to get speared In the Back by another fighter.
- Subverted in "A Golden Crown". During the Trial by Combat between sellsword Bronn and Ser Vardis, Lady Lysa calls on the latter to finish him, not realising that he's not holding off deliberately — it's because Ser Vardis can't land an effective blow on his lightly-armoured yet more skilled opponent. Ser Vardis obediently charges towards Bronn, who expertly dodges him and inflicts a fatal wound.
- Rome. During the assassination of Julius Caesar, Brutus just stares in shock as Caesar is stabbed multiple times, an unused dagger dropping from his hand.

- In The Protomen's song "The Sons Of Fate", the fight between Megaman and Protoman is watched by the people of the City.

- During a battle against a Martian saucer in the Willams pinball table Attack from Mars, once the player inflicts enough damage such that its Life Meter fully depletes, one of the citizens from the city the player is defending will urge the player to deliver the final blow to the saucer with one shot into an opened sinkhole.
- In Zen Studio's pinball adaptation of the 2014 film Guardians of the Galaxy, after the player manages to land enough blows on Ronan during Rocket and Groot's fight against him, the scoring display will tell the player to "finish him" by shooting a sinkhole right under where Ronan stands.
- Especially during the Kayfabe era, where heel managers accompanied their wrestlers to the ring, the manager — upon sensing that their bloodied jobber of an opponent was finished and ripe for the kill — would signal in some manner to his wrestler to finish him off with their finishing move. Indeed, sometimes it would be a simple demand, "Finish him!"
- Mortal Kombat:
- The Trope Namer, where Shang Tsung (and, subsequently, Shao Kahn) orders the winning fighter to do this after every match. However, this only rarely comes up in the storyline, as most characters are killed in battle rather than after it.
- One exception to this is the storyline for Mortal Kombat 9. Early in the story, Johnny Cage, who believes this is a mundane fighting tournament where a lot of fighters are just in strange costumes, defeats Baraka and is subsequently ordered to "Finish him!" by Shang Tsung. He refuses. Cyrax is later offered the same opportunity after beating Cage and he also stands down. Later in the game, Shao Kahn orders Kitana to kill a Shaolin monk she had just defeated. She refuses, which causes Kahn to kill the monk himself.

As he floats there helpless, Terenas Menethil resurrects the raid group, and orders the players to finish off Arthas.
- The conclusion to the Archimonde battle at Mount Hyjal (Caverns of Time version) is this. When you get him down to 10% health, he Turns Red and unleashes far more powerful attacks...but the raid is buffed with Blessing of Elune, rendering all raid members immune to his attacks. While there is a limited duration to that buff, the wisps around Mount Hyjal are also attacking, pretty much guaranteeing that he dies before the buff expires.
- The MechCommander intro video.
- In Mass Effect 2, Commander Shepard can, if his/her Renegade points are high enough, encourage Jack to kill one of her childhood inmates to prevent him from reopening the facility (or alternately use paragon material to talk her out of it).

You also get informed that he went down fighting the Reapers and protecting evacuation shuttles.

When Zuko turns his back to leave, Zhao dishonorably tries to strike from behind despite having already lost confirming that he really is truly evil.
