A frequent Drama-Preserving Handicap, this trope is in play whenever a character has to undergo the task of beating, outwitting, or capturing another character without causing them excessive harm, provided causing ANY harm is even an option.
Picture this scenario. Let's say that Carl has assigned Bob and Alice the task of capturing an experimental beast that has escaped from the facility. No problem, right? The two are a bonafide Action Duo capable of taking down massive troops of goons on their own. How hard can taking down and reclaiming one beast be? Well there's just one thing. Carl says that the monster cost the facility so much money that losing it would set the program back immensely. Thus two must retrieve it alive and unharmed. Oh Boy....
There are many ways this can be brought about. Perhaps a character must subdue a beast without hurting it as per requirement of a Hidden Purpose Test or the like. Perhaps a character finds out that a monstrosity is actually a loved one and they must find a way to restore them without killing them. Another case may be having a Badass Pacifist feel the need to set an example for others who feel that only force can get anything done.
Other conditions that can bring this about include:
- Old-School Chivalry which can invoke this trope by not allowing a male character to harm a female.
- Endangered Species which can invoke this trope by forbidding the characters from harming a creature on the brink of extinction.
- Wouldn't Hurt a Child where a character can't throw a punch at a juvenile.
- Elder Abuse being taboo which keeps a character from hurting or even wanting to hurt a really old person.
- The target is crucial for some purpose so damaging or killing them is a big no-no.
- The target itself is a Hair-Trigger Explosive—their body is so unstable that excessive force could cause a disaster like an explosion.
- The foe is too pathetic or weak for the character to fight seriously so they go easy on them out of pity.
- The law means you'll cause a diplomatic incident.
- The enemy has assimilated or formed some kind of link to an ally or loved one which means that destroying the enemy would mean taking out their loved one too.
As you can expect, this trope is the ire of any Blood Knight. After all, fighting is supposed to be a thrilling activity where one can cut loose and show how just how badass they are. Why does one have to restrain themselves against an enemy that's free to kill them if they wish? The Psycho for Hire also tends to get put on the spot a lot when it comes to this. Sure he may have the skill set, finesse, (and often Lack of Empathy), for easily dispatching of targets, but if he suddenly gets a request from a client to not kill, then it'll become one heck of a struggle for them to hold themselves back.
Of course just how hard this actually proves to be depends on the fighters' abilities and just what the target is. And a key thing to note overall is that the character doesn't have to be required by another to not inflict excessive harm. A self-applied No Harm Requirement is as much a case as one dealt by another character.
That said, things can definitely go wrong when trying to invoke this trope. If an attempt to adhere to this trope goes horribly wrong, you have Pacifism Backfire. And if the one restricting themselves gets killed, you have Suicidal Pacifism.
Archetypes that tend to have this forced upon them to their dismay include the Blood Knight, Psycho for Hire, Sociopathic Hero, Unscrupulous Hero, Token Evil Teammate, the Ax-Crazy, and Bad Powers, Good People.
Compare/Contrast Escort Mission where one is assigned the task of escorting a character safely and Thou Shall Not Kill which is a whole philosophy around not killing. (Although non lethal violence tends to be permissible.) Also compare <Hero> Must Survive, a video game trope where the player must keep the hero alive lest they want a Game Over, and the even more extreme No-Damage Run where the player can't take any damage at all.
A funny tactic sometimes used to get around this is Stop Hitting Yourself where the character keeps their hands clean by getting the target to pound themselves. Defeat by Modesty, Paralysis, Forced Sleep, and Mind Control are other common means of pulling this off.
Super Trope to Bring It Back Alive which concerns retrieving a beast or some other thing alive, I Want Them Alive which is an often villainous variation where the villain demands that the heroes or some other party be brought back alive, Can't Kill You, Still Need You where a character really wants to kill another but can't out of a need to keep them alive, and Sheathe Your Sword where this is actually the only way to win.
Contrast Violence Really Is the Answer
- Berserk: A particularly depraved aristocrat (who'd slept with Griffith once in exchange for funding the Band of the Hawk) finds himself on opposing sides. When they meet, he tells Griffith his men were ordered not to harm him, and thinks it'll be enough for Griffith to submit then and there. Astoundingly enough, Griffith didn't feel the same for him, and kills him on the spot.
- Fairy Tail: Defied by Gajeel during the Phantom Lord arc. Jose, the Big Bad of the arc, leaves Gajeel to watch over Lucy who they kidnapped as requested by her father. Given that her father wanted her back to seal a wedding proposal with a rival company's son and that she's well, his DAUGHTER he must certainly have made it clear to Jose that he wanted her back in one piece, despite being an Abusive Parent. But despite that and Jose's orders, Gajeel takes sick pleasure in giving Lucy a No-Holds-Barred Beatdown just to get her to scream for his amusement.

Eventually Goku decides to pull a Batman Gambit and pretends to run out of power and look defeated. Naturon gloats greatly over beating Goku and decides, before finishing him off, to give him the chance to see Pan one more time. But this gives Goku the chance to yank Pan out and blow the monster away.

- In Castlevania: Symphony of the Night, the only way to access the second half of the game is to defeat the green orb controlling Richter Belmont without doing too much harm to Richter Belmont himself.
- The Thieves' Guild in The Elder Scrolls IV: Oblivion enforces a strict Thou Shalt Not Kill policy on its members; Killing anyone related to a mission for them will result in you being expelled from the guild and forced to pay a fine to one of their leaders if you want to be allowed to rejoin.
- In Dishonored, in order for the player to get the good ending and/or get the "Clean Hands" achievement/trophy, they must go through the entire game without killing anyone, including their assassination targets, to keep the chaos level low. For the good ending, they can kill a few human enemies but not too much to rise the chaos level and possibly get the bad ending. Killing rats, river krusts, and wolfhounds are the only exception to the rule.
- In Grand Theft Auto V online, the first and the last heist require half of the crew to keep the people in a bank foyer down without killing them, while the other half gets the money. Failing to do so, or killing one of them will fail the mission in the first heist and spawn N.O.O.S.E. teams in the last heist. You will however need to kill armed guards in the last mission.
- In FTL: Faster Than Light, you may be greeted by a station who will ask you to "convince" their friends to drop their career as Space Pirates by damaging their ship's hull enough to make them surrender.

However, after Lenny spills the beans, the player has the choice of killing him directly or leaving him at the mercy of the desert and vultures.
- In the Feors section of Mass Effect, taking the Paragon path means you have to disable infected colonists with special grenades or melee attacks. If you go Renegade you can just kill them, which is much easier.
- Some quests in Monster Hunter require you to weaken and capture a monster instead of killing it. This can make things tricky, since you not only need to know how to fight it, but also how much hits it can take before dieing. And by the time you can catch them, the fight may be almost over anyway.
- There's a quest in Neverwinter Nights where the quest giver asks you to steal several pieces of art from various nobles in the city. She wants the current owners left scared but alive, so she'll dock your pay if you opt to kill any of them.
- In Path of Exile, the Master Assassin's missions will usually impose these sorts of restrictions on you - such as killing a boss enemy while keeping at least one of their guards alive, or wiping out the boss's guards without killing the boss themselves. Note the "killing" part - you can bring them down to the very brink of Critical Existence Failure without failing the mission.
- In the Pokémon games, the best way to ensure the capture of a Pokemon is by weakening them to improve their catch rate. However, for some reason, Pokemon can't be caught if they're outright K.O'd. Therefore it's most effective for players to use more reserved tactics like set damage moves and moves that induce Forced Sleep or Temporary Paralysis to catch the Pokemon without risk of fully defeating them. One Pokemon move, False Swipe, was even made specifically for this purpose. No matter how strong the user is or the foe's current condition, it'll never cause a Pokemon to faint which makes it useful for getting a wild Pokemon's health as low as possible without defeating it.
- Sly 3: Honor Among Thieves has a quest wherein the objective is to put a massive feral wolf to sleep - non-lethally - by shooting it with multiple darts. Unfortunately, you'll have to sneak up and shoot the wolf at close range, because the darts are so heavy. Without getting upwind of the wolf, because it can smell the sleeping potion in the darts. The player character for this mission? A sentient turtle in a wheelchair. (Possibly subverted by the fact that the goal is the mission is to psychically posses the wolf after it falls asleep and use it to massacre a dozen or so of the level's mooks.)
- Undertale gives players the option to do this on nearly every encounter in the game. It's considerably more difficult, since it turns even a random encounter into a puzzle boss and you don't gain more health since you don't get the necessary EXP from killing enemies. Following through to the end, however, unlocks the game's Golden Ending.
- In Watch_Dogs, several side missions - particularly the Gang Hideout ones - require a non-fatal takeout on the boss. The 1-vs-1 multiplayer matches also do not allow the invading player to kill their target: if the target is hurt, they invader is warned that they're not supposed to kill their opponent, and if they do kill them, they lose the match and their target wins.
- In World of Warcraft, Keeper Karithus needs bear fur, doe hair, and sabretoothed cat whiskers to use in a ritual. He asks you to retrieve these materials from the live animals without harming them, but you don't fail the quest if you happened to kill an animal in the process.
- In X Com 2 the spokesman will give you special guerrilla missions from time to time. Half of them require you to rescue a scientist or engineer. The other half require you to kidnap a VIP without killing him. To do so you can knock him out and carry him to the evacuation point, with the carrying soldier unable to do any thing besides running. If you think you are unable to take him alive you are allowed to shoot him, but this will greatly reduce your payout for the mission.
- In higher difficulties in SWAT4, or if you just plain want a perfect score, no one has to get hurt, and everyone who doesn't start the mission incapacitated/dead has to be arrested (just in case a suspect has the bright idea to disguise himself as an hostage, which never happens in game but could happen in real life). Not you, not your SWAT Team, not the civilians, not the suspects. This is easier than it sounds as unlike in real life where they are Less Lethal Weapons, beanbag shotguns, tasers, rifles that fire tear gas pellets, flashbangs, stingers, tear gas grenades and, in the Expansion Pack, your fists are entirely non lethal and you can shoot first with these. In fact, some civilians will require to get hit by one of those before they surrender.
- Dungeons & Dragons Online:
- One mission has you being framed for a Bank Robbery, and needing to turn off the alarm to escape. The optional objective is "Do not kill any city guard". Parodied Trope, as if you get spotted but turn off the alarm anyways without killing the guards, the guards react by claiming that they are paid to kill thieves in the bank when the alarm is active, and thus letting you go on these grounds.
- The mission Stealthy Repossession requires you to not kill more than 5 kobold prophets before completing the mission. It's possible to sneak through the whole mission, but the prophets are so weak that you can also just ignore them as they ineffectively punch you.
- The mission Let Sleeping Dust Lie has you mainly fighting ogres, rakshasas, and giant spiders. You discover midway through that the spiders are friendly but Brainwashed and Crazy, and you are thereafter not allowed to kill more than 4. Killing none throughout the whole quest will net you some bonus loot.
- Hero: 108: In the episode Cheetah Castle II, the Cocky Aliens are able to take over the minds of Lin Chung's squad. Not wanted to hurt his friends, Lin Chung instead uses his hat to fake getting blasted by them. The appropriately named Cocky Aliens then exit his friends and body and jump on his "carcass" thinking they've won, only to get caught by Lin Chung, kicked 100 times by him and his cheetah comrades, and turned into fruit.
- In the My Life as a Teenage Robot episode Shell Game Jenny lets all the harmless reptiles in a reptile exhibition loose in an attempt to draw ought Silver Shell whose stolen her robotic heart. But in the chaos, a giant deadly python gets loose and begins putting the squeeze on Sheldon. Jenny tries to hold out for Silver but unbeknownst to her, Silver Shell is actually Sheldon in a robot disguise. Fortunately she comes to her senses and engages the reptile. But after she gets Sheldon free and tries to empty her arsenal on the serpent, Sheldon stops her because while he's dangerous, he's a protected species. So instead, Jenny gets the long reptile to chase her around, causing it to tie itself in a knot.
- Played with in the Secret Squirrel episode One-Ton. Secret is given orders to stop a criminal panda from destroying China Town. However, the Chief gives him orders to not harm the panda because panda's are Endangered Species which makes things rough as he's a Jerk with a Heart of Jerk. Eventually Secret stops him by getting him to beat himself up. Since he harmed a panda while being a panda, the fiend gets put into protective custody.
- Tom and Jerry:
- The cartoon "The Missing Mouse", has Tom hear on the radio that a white mouse has escaped from a laboratory after ingesting an experimental Hair-Trigger Explosive. Jerry also hears this news flash and exploits this by painting himself white and making Tom bust his back to protect from the mouse from self-created harm.
- "The Millionaire Cat" has Tom inherit a fortune, with the caveat that he will lose it all if he harms another living thing, "EVEN A MOUSE". Jerry, again, uses this to his advantage and live off Tom's fortune, producing the telegram with the "EVEN A MOUSE" warning in bold letters to remind Tom not to hurt him. Tom eventually decides money can't buy happiness.
- This trope is the reason sedatives were developed. Depending on the type of sedative, a well administered sedative can either relax a person or animal or render them unconscious, allowing them to be safely caught or treated without risk of harm.
- Wildlife rangers and animal control officers are often tasked with capturing and/or relocating animals without harming them. Even ones that can pose a direct danger to them. People of such professions will use tranquilizers, nets, grabbing hooks, etc. to incapacitate animals without harming them.
- This is how French bullfighting, or course camargaise, works - unarmed athletes have to pull rosettes off bulls' horns without harming the bull or getting gutted themselves.
