Finish Him!



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 The Messiah), he will more often than not refuse to kill his opponent, and attempt to leave without any more blood on his hands, 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 watcher (who may not know that he is next).

Related to Coup De Grace 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.

The title for this trope may be a Mortal Kombat meme, but it's not about that.

Anime

 * In Deadman Wonderland, when Ganta wins Minatsuki in the Carnival Corpse battle, the crowd demands that he finish her off. He flips them off in a lampshaded Out-of-Character Moment.

Comic Books

 * 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 Unlimited episode titled "War World".

Film

 * 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' 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.
 * Star Wars
 * Revenge of the Sith: After Anakin defeats and disarms (literally) Count Dooku he is ordered to Finish Him! by the watching captive, Palpatine. After surprisingly little fight (or, perhaps, not so surprising), Anakin complies, and instantly regrets it.

 * As well as Flash's mercy wins over Vultan and Barin.
 * Mad Max 3: 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".

 * Also used in Tron: Legacy when Clu 2 tries to make Rinzler, take down the Flynns and Quorra, only to reply, "I fight for the Users", and turns against his former master.
 * In Naked Weapon, the evil Madame M kidnaps little girls from all around the world, brings them to her heavily guarded secret island and trains them to be sexy assassins. Once they're all grown up and their training is finished, she makes all 25 of them fight to the death until only one is left standing. Talk about wasting resources...
 * John Kreese in The Karate Kid says this, just before his pupil gets his ass handed to him by Daniel's Crane kick.
 * Also used in the remake set in China. Kreese's equivalent in that movie orders one of his pupils to strike another student that he had incapacitated during practice; the student hesitates and is smacked in the face for his hesitation.
