Grandpa: Let me guess — you saved some guy's life, and he's trying to make it up to you by being your slave.
One day, Bob is strolling down the lane minding his own business. Then BANG! One Diving Save later, he has some guy pledging his loyalty to repay him for saving his life.
The concept of owing one's life to another (often referred to as a "life-debt") is simple. Someone saves your life and you must repay them, especially if you live by a strict honor code. Often it is the case that the person who saved you doesn't want someone tagging along or that the person you saved didn't want to be saved and therefore indebted to you.
Most times the person you saved becomes part of your traveling party or group of friends, and he'll stay around even after repaying you for saving him. The easiest way to repay this debt is saving your savior's life, but sometimes you can instead do something like help them get home, defeat the villain, or serve them for a period of time.
If the rescued was formerly a villain in a series with a somewhat serious tone, expect them to cash in the debt in the most literal way possible, because Redemption Equals Death. A rescued animal might pay its debt back too, in fiction.
Sometimes the saved person's attempts to make it up to the saver can be so annoying to them that they desperately try to find some way to get rid of them. This often overlaps with Disproportionate Reward, as they can see True Heroism in the smallest kindness.
Alternatively, the rescuer might take advantage of the debt that is owed by the rescued, milking the situation well past the point where a fair and reasonable person would consider the debt repaid. If this happens, look for the saved person to try and put the rescuer in danger specifically so he can cancel the debt by rescuing him. Another variant has the "slave" coming to discover that he actually didn't save the "slave-holder". This never ends well.
A standard plotline for single episodes would look like this:
- Character A saves the life of character B.
- While character A does not expect any huge return, character B insists that their strict moral code dictates that they return the favor by becoming A's servant and fulfilling their every wish.
- Character B's well intended but incompetent "help" soon becomes bothersome for character A, but they are unable to make it stop.
- Character A and friends decide to stage a scene where B will be able to (seemingly) save A's life, thus returning the debt.
- For arbitrary reasons the faux danger becomes truly life threatening, and B is able to save A's life for real.
- Optionally, Character B will now make Character A the slave, even though they are both even.
Contrast: Ungrateful Bastard.
Compare/Contrast: You Owe Me, when the rescuer invokes the debt instead of the rescued.
- Nothing would've happened in Haou Airen, had Kurumi not decided to treat Hakuron's wounds.
- Pretty much how the Sket Dance trio were formed, by way of Magnetic Hero Bossun.
- Himeko and Switch will do just about anything for Bossun as their way of showing gratitude for his guidance, although he's largely unaware of it.
- And we now have Katou Kiri (who is a ninja) pledging his loyalty to Tsubaki and insisting to help him in absolutely everything. Needless to say, Tsubaki finds this extremely irritating.
- Space Pirate Ryoko Balouta from Tenchi Muyo! GXP, blackmailed into trying to assassinate the protagonist Seina, swears to serve him after he saves her life (and her crew's families, who were held hostage, are freed unharmed). The crush on him doesn't hurt, of course...
- In Claymore, Jean was on the verge of Awakening (losing control of her power and mutating into a monster), but Claire helped her revert back to humanity. As becoming an Awakened One is considered by Claymores to be a Fate Worse than Death, she vows to protect Claire until the debt is repaid.
- Black Butler:
- Ciel owes his butler Sebastian his life - literally. At ten years old, Ciel was tortured and used as a sacrifice to summon a demon. Said demon offered Ciel his services until Ciel exacts revenge on the people responsible for destroying his life and his family... in exchange for Ciel's soul.
- Agni owes Prince Soma his life. He had him spared when he was about to be executed. In reverse of the above, Agni become's Soma's servant, and the two become fast friends.
- During the Soul Society arc in the Bleach anime, Ichigo says that the reason he's trying to rescue Rukia is because she saved his life from the Hollow in the first episode.
- Also, Shuihei Hisagi's main motivation to become a Soul Reaper was to show his gratitude to then-captain, now Visored Kensei Muguruma, who saved his life when he was a young boy.
- Tsujido, Makabe and Niihari from Speed Grapher decided to become Suitengu's henchmen after he rescued them from the corrupt rich people who tortured them almost to death.
- Played very darkly in Monster:
- Johan feels he owes a life-debt to Temna, which he repays in various interesting fashions, the likes of which only Johan can do. The primary means is by 'fixing' Tenma's promotional woes — by killing everyone who was keeping him down. The good doctor is not particularly pleased.
- Worse was the fate of General Wolf, who also saved Johan's life. After finding him on the Czech/German border, he asked Johan how the boy was feeling. Johan said, "You'll see." And proceeded to kill everyone who knew General Wolf, so Wolf could properly understand Johan's sense of isolation from humanity.
- A young military officer is about to be executed for theft by a bunch of Evil Chancellors that oppress his country. However, the child Empress orders to spare the man's life and free him. He's so genuinely touched by the young girl's kindness that he swears to repay the favor by taking her out to see the world and giving her the power to properly rule China... This is the story of Li Xingke (the officer) and Tianzi (the empress) in Code Geass.
- Wizardmon's Undying Loyalty to Gatomon started after she saved him from the brink of death.
- In Mobile Suit Gundam Wing, Quatre Raberba Winner had a Freak Out! and went in a Roaring Rampage of Revenge after his father and his older sister's deaths. However, his friends Heero Yuy and Trowa Barton fought him, and Trowa pulled an Heroic Sacrifice to make the guy snap out of it (He got better, though). Then, Quatre spends the rest of the series as The Atoner, lampshades the present trope often by telling that Trowa was his savior, and finally repays the favor by snapping Trowa out of his own Freak Out! and Roaring Rampage of Revenge. Cue to lots of happy slash fangirls (and having some non-slash fan considering the couple to be quite plausible, heh)
- Upon saving the life of Hayato Gokudera, (who had been trying to kill him), Tsuna gains his first (and most enthusiastic) member of the Vongola Family in Katekyō Hitman Reborn!.
- To a lesser degree, also happened to Yamamoto in the manga, who attempts to kill himself after an injury stops him from playing baseball. They both fall and Tsuna ends up saving both, after which, Yamamoto becomes Tsuna's second follower and Gokudera's competition for Right hand man.
- A variant shows up in The Cat Returns. Haru saves the life of a cat that turns out to be Prince Lune, son of the Cat King, but it's the rest of the cat court that showers Haru with unwanted gifts... including nearly forcing her to marry Prince Lune. As it turns out, Lune had nothing to do with the wedding, had actually been preparing to propose to a girl cat from his homeland, and ends up helping Haru escape back to the human world.
- This is effectively the entire setup for Hayate the Combat Butler, and an interesting example as both Nagi and Hayate are indebted to each other. Hayate saved Nagi from kidnappers, and Nagi paid off the Yakuza so they'd stop trying to sell Hayate into slavery or sell his organs.
- Sorata's entourage in Mouse. That's what you get for curing one's mental illness, rescuing one from an abusive guardian, and helping one get over Arrheophobia.
- Terry Sanders Jr. in Mobile Suit Gundam: The 08th MS Team is fiercely loyal to his commander Shiro for not only saving his life the last time his "curse" kicked in, but also for helping him break said curse when it should have fallen on him again.
- In Demon Slayer: Kimetsu no Yaiba, a legendary Demon Slayer once saving Sumiyoshi from falling prey to demons made the coal seller express utmost gratitude towards his savior, wanting to pass Yoriichis life story, if nothing else, to his descendants. Sumiyoshi ended up passing something more tangible to his descendants than a mere tale, in the form of the secrets for the very sword arts his savior once used to protect him.
- Naruto: Zabuza saves Haku's life as a child, and in repayment Haku happily spends the rest of his life as the ninja equivalent of a slave. In the end, he even dies for him, causing Zabuza to realize just how much he owed Haku, and not the other way around.
- In Captain Harlock, Miime is "the woman who gave her life to Harlock" ever since he saved her life from a giant carnivorous plant.
- Mahou Sensei Negima!: This is the reason Fate's group of female subordinates are so fiercely loyal to him. They are all war orphans whom he took in and cared for following the last war. He offered them the chance for a normal life, with enough money to put them through good schooling, and they refused, preferring to aid him directly in his own plans.
- An episode of Pokémon has the Girl of the Week enthusiastically declare this word-for-word to Ash after he saves her and her Vulpix during an attack by Team Rocket, while suggesting the possibility of something more. One of the rare times in which Ash isn't portrayed as completely Oblivious to Love, instead coming across as somewhat Allergic to Love.
- This is the thing that starts off the plot of Hana the Fox Girl. Hana, an inari fox, was rescued by high schooler Fu prior to the story. Now she assumes human form and seeks out Fu so she can repay that kindness.
- One Piece: Trafalgar Law owes everything to Corazon, aka Donquixote Rocinante, the younger brother of his former boss Donquixote Doflamingo. On top of being the first person to show him compassion for his dark past, Corazon saved his life by stealing the Op-Op Fruit for him to eat — the act of which eventually cost Corazon his life. Law is so indebted to him for this that he admits that the only reason he survived to this day is to fulfill Corazon's wishes and avenge his murder by killing Doflamingo. It is his love and devotion that is the ultimate driving force of the Pirate Alliance saga.
- Lyrical Nanoha:
- Unlike most familiars, Arf's loyalty to Fate isn't because of any magical contract but rather because Fate turned her into a familiar to save her life and left the terms of their contract open-ended (familiars in Nanoha die when their contract has been fulfilled).
- Zest saved Agito from being experimented to death at an illegal laboratory, so she swore to follow him. This makes it all the more tragic that there is literally nothing she can do to prevent his death, so she has to settle for respecting his last wish for her to go with Signum (who was responsible for his Suicide by Cop).
- Izetta from Izetta: The Last Witch acknowledges multiple times that her life was saved by her Only Friend Princess Finé from an angry mob that attempted to lynch her. This drives Izetta's decision to use her powers to save Princess Finé's country.
- Tohru's relationship with Kobayashi is part this and part Rescue Romance in Miss Kobayashi's Dragon Maid. When they first met, Kobayashi saved her life by removing a holy sword from her back and she has been serving as Kobayashi's maid ever since.
- Elfen Lied: One of the only positive traits shown by Bandou, who is otherwise a misogynistic, amoral Psycho for Hire, is a belief that he should fully repay any debts that he owes. When 13-year-old Mayu (accidentally) distracts Lucy at a critical moment and saves his life, he gives her his phone number and tells her to call him if she's ever in danger. He makes good on this promise later in the manga, and saves Mayu from the "Unknown Man".
- Roberto Hongo in Captain Tsubasa feels this way towards Koudai Ohzora, who saved him when he tried to commit suicide over his ruined football career. He tries to repay the debt by training his son Tsubasa and forming him into a world-class player.
- In Goddess Creation System, when Xiaxi needs the help of the Wang Pu brothers, she uses this as an excuse for why she didn't return to them even though she didn't actually drown like they thought. She claims that the crown prince saved her life and therefore she needs to repay her debt to them. Suffice to say, the truth is a lot more complicated, especially given that he didn't save her life.
- A minor version in Star★Twinkle Pretty Cure. Elena/Cure Soliel helps out Yuni/Cure Cosmo in rescuing Fuwa from the Notraiders due to the fact that part of that episode's plot was caused by Yuni. When Yuni immediately goes back to her Aloof Ally status and tries to bail once the day is saved, Elena stops her from leaving. When Yuni casually mentions that she's in Elena's debt, Elena immediately invokes this to get her to stop running and officially become the team's Sixth Ranger.
- A flashback in Kaguya-sama: Love Is War revealed that Kaguya saved the Mass Media Club president about a year before the story began, with her mentioning to Hayasaka that she only did it so that she'd owe her a favor in the future (this was during the height of her Ice Queen days). We Want to Talk About Kaguya implies that she cashed in this favor to insure the Mass Media Club's support in Shirogane's reelection.
- Played straight in The Demon Girl Next Door, with Sakura's core within Yuko keeping the latter alive. When Yuko found out about this state of affairs, she wanted to remove Sakura's core and restore her for Momo's sake, but in Yuko's current condition, she'd die without Sakura's core. Momo demands of Yuko to not even think about removing it until she's much stronger and doesn't need Sakura's support.
- DC Comics Bombshells: The Joker's Daughter rescued Killer Frost, Zatanna, and Raven from the Nazis when they were children and raised them, but afterwards makes them serve her and the Nazis. While Killer Frost is extremely grateful and willingly serves her, Zatanna and Raven know she is evil and repeatedly try to leave, but Joker's Daughter guilt trips them into staying by bringing up how she saved their lives. Eventually, Zatanna, Raven, and Miri Marvel defeat the Joker's Daughter and take away her powers. They spare her life and Zatanna declares their debt is repaid.
- In LightningOnTheWave's Saving Connor AU Harry Potter cycle, the centaurs wind up kidnapping Draco Malfoy during the first year and threatening to kill him unless Harry can break a rock with his mind. He succeeds, and then when Draco insists he owes a life debt for this, Harry says he should pay it off however he likes. Draco uses this to force Harry to come to his house for Christmas.
- In Sinnatious' The Fifth Act this trope is used more subtly than usual but has an incredible impact on the plot. Accidentally-time-traveling Cloud Strife reflexively gives Genesis Rhapsodos some of the magic water from Advent Children and cures his...genetic deterioration, thereby throwing off the plot of Crisis Core entirely, since the Commander then has his life back and doesn't mount a rebellion against Shinra or leave Sephiroth even more emotionally isolated and prone to going nuts. For the rest of the story, Genesis is guided by his awareness that he owes Cloud his life.
- Ace Combat: The Equestrian War: Cloud Kicker to Fluttershy. It helps they are both members of a team comprising the main heroines. The favor is returned in chapter 17.

- In the Harry Potter fanfic Pride Of Time, Sanguini feels this way towards Hermione after she saves him from a Death Eater.
- In Zero no Tsukaima: Saito the Onmyoji, Saito saves Princess Henrietta from an assassination attempt. Because of this, he is entitled to any reward bar a Grant of Nobility (which would have been on the table had he risked his life in the process). After some time to think, he asks for a house.
- The Bridge: Destroyah serves as Xenilla's Dragon because he found and healed her after her battle with Godzilla Senior.
- In crawlersout, Grindelwald's attempt to murder Fem!Harry ends with him owing a life debt to the woman he just tried to kill. Unusually for Grindelwald, he seems to be unaware of this (Harry is the one who realized this and asked Hermione just to be sure), but that's probably because he's become obsessed with Harry and how she survived the attempt to take notice.
- In The Crystal Court, Ruby first falls for Sapphire when she accidentally bumps into her and Sapphire waved it off. As simple as this sounds, fae are not usually clumsy and Sapphire was high enough in the hierarchy to have her executed for the "insult." Because of this, Ruby feels she owes a life debt to her.
- This is why the Shadow Triad follows Ghetsis in Chrysanthemums. He saved them as children and so they follow him faithfully. It isn't until Iris befriends Cilan that this changes.

- In Mulan, Mulan/Ping saves Captain Li Shang when s/he causes an avalanche on the mountain pass to decimate the Hun army. A few minutes later on in the movie after it is revealed that she is a woman, and any woman pretending to be a member of the Imperial Army must be killed. Captain Li refuses to kill her, however, saying that by sparing her life, his debt is repaid. He still kicks her out of the Army, and leaves her on the cold mountain, though.
- This is how Puss in Boots joins the gang in Shrek 2. But if you think about it too hard, it seems a little strange: Puss feels in debt because Shrek had him at his mercy and didn't kill him, when a few seconds earlier Puss had had Shrek at his mercy and paused to gloat and carve his initial into a tree. He didn't really look like he was about to kill anyone. If that isn't enough to discount the incident, Shrek and Donkey were contemplating doing something to him until he talked his way out of the situation, and then (much to Donkey's disgust) Shrek got distracted by the cute, so it wasn't really a straight out sparing of his life. But it all gets resolved by the end.
Shrek: Aww, look, he's purring!Donkey: Oh so now it's cute!
- This is how Captain Gutt rallied his army of pirates in Ice Age: Continental Drift.

- In 3:10 to Yuma (1957), Dan Evans is trying to get bandit leader Ben Wade on the eponymous train to Yuma, where he will stand trial. Wade's bandit gang corners Evans at the train tracks, and all Wade has to do is duck and Wade's men will shoot Evans down. Instead, Wade yanks Evans onto the train.

Nasir says "I am your prisoner — your slave if you wish it" but Balian still lets him go. This comes in handy later, at the battle at Kerak, where Nasir turns out to be a general in Saladin's Army, not some guy's servant after all. He spares Balian's life.

- Azeem, the Moor in Robin Hood: Prince of Thieves.
- Subverted in the 1994 movie The Shadow, in which the title character conscripts people he saves into his network of informants and assistants.
- Star Wars and the Star Wars Expanded Universe is rife with examples:
- Chewbacca to Han Solo and for that matter, Wookiees in general. For example, Zaalbar in Knights of the Old Republic. The Wookiees even have a term for it: a Life Debt. Although in rare cases, the life debt can be seen as a special form of slavery, as is the case with Hanharr in Knights of the Old Republic II: The Sith Lords. But for the average Wookiee, calling a Life Debt 'slavery' is a good way to have your arms torn off.
- The Noghri to Darth Vader, a debt that Leia to inherits/earns by virtue of being his heir.

- In White Christmas, Phil saves Bob from a falling brick wall in World War II. As Bob is already an up-and-coming entertainer at that point, Phil guilts him into agreeing to be partners, and sure enough to two are quite successful.

I beckoned to him again to come to me, and gave him all the signs of encouragement that I could think of; and he came nearer and nearer, kneeling down every ten or twelve steps, in token of acknowledgment for saving his life. I smiled at him, and looked pleasantly, and beckoned to him to come still nearer; at length he came close to me; and then he kneeled down again, kissed the ground, and laid his head upon the ground, and taking me by the foot, set my foot upon his head; this, it seems, was in token of swearing to be my slave for ever.
- In the Memory, Sorrow and Thorn books Simon saves the life of a Sitha. The Sitha, Jiriki, gives him a white arrow as a token of debt, which Simon later tries to return after Jiriki saved him.

This especially becomes a burden for Ari when Dante takes his time in the hospital to realize he's in love with him and tells him so. Ari doesn't want Dante to apologize or thank him, much less confess because of it. Thankfully for Ari, Dante's family was moving anyway so he doesn't have to deal with the fallout for long.
- The Alien series novel Music of the Spears has an interesting subversion of this, with a Japanese hitman who feels he owes his life to the Yakuza boss who killed his parents in front of him when he was a kid, because the boss decided not to kill him and his sister. Instead, the boss raised the guy as his hitman and the sister as his concubine. And, in Japanese tradition, they hold nothing but feelings of gratitude to him for his big box of "I Didn't Kill You".
- In J. R. R. Tolkien's The Silmarillion, Finrod Felagund gives Barahir a ring to symbolise the fact that Barahir saved his life, and swears an oath to return the favour sometime in the future (including Barahir's descendants). Later, Finrod repays the debt by saving Beren, Barahir's son.

- One of the rules of magic in the Harry Potter universe is that saving a magic-user's life creates a "life debt" which they're obliged to repay at some point in the future. According to Dumbledore, this is an unbreakable kind of magic. Not much is made of Ginny's life-debt to Harry, since they end up together anyway, but Wormtail's debt becomes a major Chekhov's Gun in book seven. However, it seems to be more of a custom than a law of magic-Barty Crouch Sr, for example, saved his son's life, but the son later killed him.
- This explicitly becomes the attitude of pretty much the entire Weasley family towards Harry after he saves Ginny from a basilisk, Arthur from Nagini the snake, and Ron from poisoned mead.
Molly: (hugging Harry) Oh, Harry, what can we say? You saved Ginny...you saved Arthur...now you've saved Ron...
Harry: Don't be...I didn't...
Arthur: Half our family does seem to owe you their lives, now I stop and think about it.

- For example, a farmer who ended up marrying a beautiful girl who was actually a crane whose life he saved.
- In the Parrish Plessis series, the Cabal Coomera take this very seriously. If any member of the Cabal saves your life, you owe the entire Cabal goma — blood debt. And in their eyes, goma can never be fully repaid, meaning you'll owe them favors for the rest of your life.
- Played with in A Song of Ice and Fire: Arya Stark is given three "lives" in exchange for saving a skin-changing assassin along with two other dangerous murderers.

- D'Nal Cord in the Prince Roger series becomes the eponymous prince's asi after Roger saves him from one of planet Marduk's many (many) dangerous monsters. This is standard when someone saves a Mardukan's life without some ties of clan or family obliging him to do so. He also serves the role of Old Master, aiding in Roger's Character Development. Later, he winds up getting an asi of his own in Pedi Karuse, whom he saves from pirates. They eventually get married.
- In the Dungeons & Dragons novel The Savage Caves, when newcomer Naull happens to be in the right place at the right time to rescue Lidda, Redgar, and Jozan from being killed by giant spiders, Lidda then claims she now "owes Naull one". She then begs Naull to be willing to go to anywhere but the town the trio just left, or to continue on the quest to kill all of the spiders. Unfortunately for her, Naull rather likes the whole "killing the spiders" idea. Of course, considering she didn't seem to think she owed Jozan one for saving her from being hung for thievery in said town in the first place, and everyone else seems confused by her "debt", she may have just made it up to try to weasel out of the quest she was forced into in exchange for being saved.
- In The Mark of the Lion, Rashid pledges his life to Hadassah when she rescues him after his master leaves him to die.
- The northern barbarian tribes in the Heralds of Valdemar novels have this as part of their code.

He clears it in the next novel by acting as Darian's guide.
- In Woken Furies, Takeshi Kovacs became friends with Radul Segesvar by saving his life back when they were both in a gang; Radul felt he owed Kovacs a debt and spent the next 200 years paying him back in the form of favors. When he ends up betraying Kovacs, Kovacs realizes that the two of them never actually liked each other that much, and it was only the debt that had kept their friendship together for so long.
- It's further subverted in that a flashback shows that Takeshi was actually saving his own life at the time. Furthermore Radul betrays him because there's an Evil Knockoff of Takeshi involved (his personality from his younger, more sociopathic days downloaded into another body), so which version of Takeshi does Radul owe his life too?
- Parodied in Jeeves and Wooster when Bingo Little tries to play this card:
Bingo: Bertie, I saved your life once.Bertie: When?Bingo: Didn't I? It must have been some other fellow, then.
- In Pact, Blake Thorburn feels that he owes his life to his friends, as they variously saved him from a cult leader while he was homeless, helped him off the streets, or otherwise gave him help when he was badly in need of it and they had no obligation to do so. He therefore feels that he owes them a debt that he can never repay, and is hesitant to ask them for anything without ensuring that it's weighted in their favor first, which doesn't do him many favors when it comes time to break the Masquerade and tell them that magic is real, and it wants to kill him. Conversely, his friends feel that, as he's their friend, of course they'll help him with the supernatural menaces that want to kill or enslave him.
- In the Spiral Arm series, Donovan saves Billy Chins from a lynch mob on Harpaloon. Afterwards, Billy insists that by the custom of atangku, Billy's life now belongs to Donovan and he is obligated to become Donovan's servant. Billy is actually The Mole, and he engineered the situation in order to infiltrate Donovan's group.
- Discussed in The Death Gate Cycle. Under Patryn law, if one Patryn saves the life of another Patryn, any and all disputes between the two of them are settled in the rescuer's favor. Patryns in general are too proud and independent-minded to offer themselves totally in service to another except in exceptional circumstances, but when a debt is there they always acknowledge and fulfill it.
- Why Peter saves Tris' life in Insurgent. He claims to only think in term of debts, and couldn't conceive of doing anything for someone unless it was to get them to owe you a favour.
- In Children of the Night, Diana rescues several kidnapped Romani children. The clan considers themselves to have an honor debt to Diana until she finally finds something they can do to clear the debt in Burning Water.
- The Witcher world has a custom called the Law of Surprise. If someone saves another person's life, they may ask for what the rescuee has, but yet is not aware of. If it turns out to be a child, a bond of destiny is formed between the child and the rescuer. This is the witchers' favorite recruitment method. Ciri, Geralt's adoptive daughter, was promised to him in this exact way, after he saved her father's life and invoked the Law as per witcher tradition.
- In The Witchlands, the Nomatsi people have a concept of life-debt, wherein when someone saves your life, you have to either repay them in kind or spare them if fate brings you into conflict. It brings Aeduen and Iseult many headaches, as the two Nomatsi are on opposite sides, yet keep saving each other's lives.
- In The Spirit Thief, large part of the reason behind Nico's Undying Loyalty to Josef is that he saved her life when everyone else either didn't care or actively wanted her dead.
- The Neandertals in Earth's Children feel very strongly about life debts. Part of the ceremonial swearing-in for a healer involves making them responsible for the entire species, so they can't accumulate life-debts from their patients.
- Villains by Necessity: Despite being found out as The Mole, when Robin, due to his fear of heights and a minor head injury, falls off the edge of a cliff, landing on a small ledge and is paralyzed with fear, Blackmail "hires" Sam to help him save the centaur's life. This causes Robin to join the villains (along with wanting to save the world from destruction, which also would kill him), because, by his people's customs, he owes them a life-debt, practically saying the trope's name — "I owe you, Blackmail in particular, my life."
- Isaac Asimov's "Robbie": Played With because Robbie saved Gloria, who didn't even notice she was in danger. Her mother, Mrs Weston, had noticed, and because Robbie saved Gloria by grabbing her out of danger, she finally acknowledges that he is safe. To repay the debt, Robbie is allowed to rejoin the house as Gloria's nursemaid.
- The Han Solo Trilogy: Chewbacca, according to his culture, owes Han a life debt for saving him. This means he makes it his duty to serve and protect Han. At first Han finds this annoying, but slowly warms up to him and then the pair grow into fast friends.
- For that matter, Han's reason for saving Chewbacca in the first place is also along these lines. A Wookie who had been something of a mother figure to Han gave her life for him; since he couldn't repay the debt directly to her, he decided to pay it forward by helping another member of her species. When Chewbacca first comes around, Han tries to use this fact to convince him that he doesn't owe Han anything (since Han was just paying back a debt of his own), but Chewbacca doesn't buy it.
- Shadow of the Conqueror:
- The girls that Daylen rescues from slavery aboard the Maraven are all intensely grateful to him, however he tries to hide it, with Sharra the most expressive about it.
- Sain is initially a Defiant Captive, but his attitude towards Daylen improves by orders of magnitude after Daylen uses his sunforging abilities to undo the sunucles that Blackheart used to hold Sain and his mother captive.
- During the climax, Daylen goes out of his way to save Lyrah from the ambush that the Dawnists prepare with their Depleted Phlebotinum Shells. While it certainly doesn't make her forgive him, it's a major factor in reducing the apocalyptic levels of well-deserved hate that she feels for him, to the point where she returns the favor and saves him when he falls off of the Bloodrunner.
- Game of Thrones:
- Ser Loras Tyrell says this word-for-word to the Hound after Sandor Clegane saves him from the Mountain, and Loras decides to repay the debt by forfeiting the final round of the joust and giving the championship title (plus the substantial award money) to the Hound.
- Jaqen H'ghar offers to kill three people for Arya in exchange for saving his life as well as Rorge and Biter.
- Ser Dontos Hollard pleads this to Sansa in "Two Swords." Subverted when he turns out to be an agent of Littlefinger, motivated by his money more than gratitude.
- Subverted with Mirri Maz Duur. Daenerys saves her from being raped and murdered by her husband's khalasar, but she turns against them anyway, pointing out that her temple had been burned, her fellow villagers murdered, and she'd been raped three times already before Daenerys made an appearance. "What is life worth when all the rest has gone?"
- Robett Glover did not join the Stark restoration army because it was the Boltons that helped them liberate their lands from the Ironborn. After the battle, he asks for forgiveness knowing full well that Jon could punish him. When Jon simply responds "There is nothing to forgive.", the look of relief on his face is immediately followed by Glover's declaration that he will fight behind Jon Snow from that point on.
- Played with in The West Wing episode "In the Shadow of Two Gunmen"-
Sam: I didn't want you to feel beholden to me. I didn't want it to be like an episode of I Dream of Jeannie where now you gotta save my life and the time-space continuum...C.J.: Sam?Sam:...with you following me around with coconut oil and hot towels.C.J.: Coconut oil?Sam:: I'm just saying....C.J.: Sam, I don't feel beholden to you.Sam: Why not?

Colby finally tells Carter what he really thinks in "Trust Metric".
Colby: Dwayne, I really wish somebody else had pulled me out of that fire.
Colby: Because I hate owing you.
- In The Fugitive episode "The Evil Men Do", Kimble rescues a stable owner from an out-of-control horse, and the owner a former mob hitman attempts to repay the debt by killing Lt. Gerard.
- Subverted when the mobster's wife points out that he's really not doing it for Kimble as much as for himself; he just plain likes killing.
- The concept is rejected by a mob boss in "A Clean and Quiet Town". His son explains that his men have been roughing up Kimble at the request of the One-Armed Man, who saved his life in a bar fight. The mob boss replies that you don't have to give a small time crook like that anything.
- An episode of of The Odd Couple has Oscar saving Felix from falling out their window. Guess what happens next.

- In the pilot of Star Trek: Voyager Tom Paris saves Chakotay and jokes that his life belongs to Tom now. Chakotay responds "Wrong tribe!" but repays the favor by keeping the rest of the Maquis from harassing Tom.
- In season one of The O.C., Jerk Jock Luke starts being nicer to Ryan after Ryan saves his life.
- We find out on The Big Bang Theory that the main reason Leonard puts up with a lot of Sheldon's demands is at least in part because Sheldon saved Leonard from being blown up in an elevator with a canister of poorly mixed rocket fuel.
- The Andy Griffith Show: In one episode Andy saves Gomer from a fire, only to have Gomer come in and play "live-in servant", much to Andy's dismay. He gets out of it by pretending to be in danger so that Gomer can cancel the debt by "saving" him.
- In the Star Trek: The Original Series episode "Amok Time", Kirk acknowledges a life debt to Spock when deciding to disobey orders, thereby risking a court martial, because Spock is facing a life-threatening emergency.

- Subverted in Attila. Flavius Aetius arranges an assassin to kill the Emperor, but personally kills the assassin as he's about to strike so the Emperor will feel indebted to him.
- Hercules: The Legendary Journeys establishes that Iolaus used to be a thief; Young Hercules would later elaborate that he ran with the nastiest gang in the region and was lucky to be sent to Cheiron's Academy of Adventure as part of his probation instead of sent to prison outright. It was becoming Fire-Forged Friends with Hercules that caused Iolaus to give up being a thief and turn his life around. Iolaus paid back the debt by becoming Herc's most reliable ally and dedicating his life to helping others. Through the course of their adventures, they literally saved each other's lives numerous times.
- In Traveller Aslan have an intricate web of customs regarding gratitude. In the volume Sword Worlds, an Aslan clan is too busy with a war to defend one of its client clans against aggression. A group of human political refugees provided assistance to the client. As the patron could not provide protection and the humans could, the patron had to arrange passage through Aslan space. This is more "I owe you my honor". But to a proper Aslan honor is more then life.
- This definitely seems to be a belief held by the desert dwelling Chanari of Mars in Rocket Age, since it's one of the first character hooks on offer for them.
- Zaalbar to the main character in Knights of the Old Republic.
- For the evil players, Zaalbar's life-debt is, in fact, a form of slavery, as he will do anything you tell him to if you remind him of the life-debt. This includes killing Mission if she angers you or gets in your way, even though he's extremely protective of her.
- However, he won't do it unless you use Force Persuade on him, and if you take him on the Star Forge afterwards he'll attack you.
- Hanharr in Knights of the Old Republic II: The Sith Lords is a subversion, or possibly Deconstruction of this trope: he despises the Wookiee tradition of life-debts but feels obliged to honor it, so he seeks to kill anyone who saves his life to relieve himself of the debt.
- But exploited like everything else by Kreia, who resurrects a mortally-wounded Hanharr and gloats "I saved your life, beast. That makes it mine." Hanharr does not make a move to kill Kreia for this, realizing she is way out of his league. Kreia was cooked up by the same author as The Nameless One (see below).
- Defied in the MMO spinoff of the first two games by Jakarro and Bowdaar. Players can try to invoke the life debt with Jakarro after they free him and his droid companion from a Manaan prison, but he'll completely refuse to do anything of the sort. Bowdaar, meanwhile, joins the Smuggler's crew after receiving some back-up from them during a tough fight, but while he's grateful for the help, he'll make it clear that he doesn't owe the Smuggler a life debt (and since he just got freed after spending a century as a slave, it's understandable why he wouldn't want someone else owning his life).
- For the evil players, Zaalbar's life-debt is, in fact, a form of slavery, as he will do anything you tell him to if you remind him of the life-debt. This includes killing Mission if she angers you or gets in your way, even though he's extremely protective of her.
- Dragon Age:
- Sten, in Dragon Age: Origins, swears himself to your service after you rescue him from a cage where he was locked up to starve or die when the Darkspawn invasion arrived.
- This is a subversion, as Sten believes that your mission is doomed to fail. But he would rather atone for his crimes by falling in battle than starving to death or serving as bait for the darkspawn.
- This specific subversion turns up a number of times in Origins and even more in Awakening, with multiple characters receiving the Joining in lieu of an execution. The logic is that the Joining has a reasonable chance of killing you immediately, will slowly kill you otherwise, and being a Grey Warden carries an obligation to fight the Darkspawn in every way possible. The Warden invokes this version of the trope with Duncan, and Loghain, Anders, Nathaniel, Sigrun, and Velanna all invoke it with the Warden, taking induction to the Grey Wardens over an execution for their past crimes. However, not all of them are particularly grateful about it.
- Played with in Dragon Age II. If Hawke is in a rivalry with Aveline and Hawke sides with the mages in the endgame, when the Templars order her to attack Hawke, she will refuse. She owes Hawke her life and thus will not kill him/her. However, by refusing to kill Hawke, she declares her debt repaid and that she wants nothing to do with him/her ever again.
- Sten, in Dragon Age: Origins, swears himself to your service after you rescue him from a cage where he was locked up to starve or die when the Darkspawn invasion arrived.
- In Planescape: Torment, a past incarnation of the protagonist deliberately indebted both Morte and Dak'kon in this way... with the added twist that he himself can't die, so there's no way to repay the debt.
- It gets worse as Dak'kon's debt also flies in the face of the tenet of both his culture and their Evil Counterpart: never be enslaved again. Oh, and The Nameless One's former self knew all this and orchestrated said life debt for his personal gain.
- Played straight in Beyond Good & Evil. After Jade rescues Double H from an alien torture chamber, he pledges his loyalty to her and becomes one of her sidekicks.
- Final Fantasy Tactics plays with this one when siblings Rapha and Marach argue over whether or not they owe anything to the nobleman who took them in after they were orphaned. Marach argues that they do, since he saved them from starving to death or living in poverty. Rapha, on the other hand, thinks that any obligation they might have is negated by the fact that he was the one who burned their village down and killed their parents in the first place. Oh, and it's heavily implied that he raped her. Marach eventually comes around, but it takes longer than you'd think.
- In Grand Theft Auto V, heist driver Taliana Martinez needs to be rescued before you can recruit her for heists. Once she is rescued, you discover that she is very skilled and only takes a cut of 5%.
- Subverted in Neverwinter Nights 2; after rescuing Neeshka from the soldiers, there is the conversation option of "I saved your life - that means I own you." However, the game doesn't allow the player to follow through with this statement. Of course, since the player (not the main character) can take full control of party members, it could be considered as no subversion at all.
- Somewhat darkly inverted in Raven's case in Tales of Vesperia. It's less "I Owe You My Life" and more "You Owe Us Your Life".
- More amusingly inverted at the end of Maximo: Ghosts to Glory. Maximo takes The Grim Reaper's "I owe you one" speech to its logical conclusion and immediately enlists him as his partner.
- Taken to hilariously ludicrous degrees in the comedy game The Space Bar. Every time Alias's partner Maksh begs Alias over his PDA to hurry up and rescue him before the Big Bad does something horrible to him, there's a flashback about how Maksh risked his life to save/help Alias or Alias' mother, as a guilt trip to motivate Alias. Which ends up easily equaling over 10 different times Maksh has saved Alias' life somehow based on all the flashbacks. And it turns out that there's actually even more times beyond that, and Alias and Maksh can't even agree on which ones actually "count".
- Mass Effect: Should Shepard choose to spare them, the rachni will send a message to Shepard that they can count on the rachni's full support if and when the Reapers invade the galaxy. They make good on this promise in Mass Effect 3, although they have to be rescued (and spared) again before they can do so.
- The drell race has this as a species-wide motivation. The hanar rescued them from the slow death of their home planet, and so they handle all the Dirty Business which the pacifistic hanar can't do themselves.
- If the genophage is cured and Wrex is still alive, this essentially becomes the krogan attitude to humanity.
- In Shin Super Robot Wars, Heero Yuy and Zechs Marquise for Neo Zeon because for Char Aznable had saved their lives. In the case of Zechs, Char claims that Zechs surviving was pure luck and Char was just at the right place at the right time.
- In the Dark Parables series, this trope is in play - but it takes four games for it to be revealed. In the first game, the detective saves Princess Briar Rose from the power of her evil godmother. The two then go their separate ways and the player doesn't expect to ever see Rose again. Flash forward to the fourth game, where the detective and the members of the Red Riding Hood Sisters are all in grave danger from the Wolf Queen. Suddenly, a beautiful sorceress emerges from the shadows, reminding the detective that she once saved her life - "...and now I've come to return the favor."
- In the Nintendo Wii video game of Legend of the Guardians: The Owls of Ga'Hoole, main owl Shard and his friends rescue an old great horned owl named Uriah from a swarm of bats holding him prisoners. In return, Uriah mentions that he knew Shard's father once and offers to become one of Shard's wingmen for the latter saving his life.
- Fallout: New Vegas: This is a possible reason why The Courier might choose to side with Mr. House the autocrat of New Vegas. After all, House did send one of his Securitrons Victor to dig you up from your grave, take you to a doctor for bullet removal surgery, and then stick around to surreptitiously ensure your safe arrival at the New Vegas Strip. Of course, House can also tempt you with monetary reward as well as a vision for a technological renaissance.
- In Collar 6, Michael Kappel rescues a young man lying bleeding and unconscious in the snow. The man, Gunther, turns out to be an escaped Sympathetic Sentient Weapon who attaches himself to Michael's side from then on and saves his life many times over. While Gunther does become his "slave," it happens much later as the result of a naturally-forming attachment.
- Parodied in Cwen's Quest when passing stranger Riddly Lancer saves the main character's life and quickly declares her his life slave. When asked if the life slave concept should be part of his slave's personal code of honor/culture, he responds, "We wouldn't get any life slaves that way."
- Used in one Cyanide & Happiness comic, where a white guy saves a black man's life. The rescuer gets really uncomfortable when the guy he rescued swears to do his bidding and refers to him as "master".
- In Delilah Dirk and the Turkish Lieutenant, Selim clearly thinks he owes Delilah for saving his life.
- Deliberately invoked to Enforce Defeat Means Friendship in TwoKinds. When the Magi Brothers botch their assassination attempt, Flora manages to save Natani's life, and reminds him of that particular part of keidran morality. While he tries to weasel out of it, a group of humans looking for someone to blame for a border hedge being burnt threatening to skin him alive sets him straight pretty darn quick. It's later pointed out how much of a dipstick you'd have to be to want someone who was trying to kill you not 5 minutes ago to join your adventuring party.
- AFK: Sheena insists on helping Serena, because the latter saved her life. Afterward though she makes it clear Serena is no longer owed anything from her.
- Family Guy subverts this when Stewie helps Brian out of a tight spot, reminds him of The Brady Bunch episode mentioned above...and then asks him to repay the debt by taping that episode for him.
- Hey Arnold!, as demonstrated by the above quote.
- Played with a little, because Arnold eventually decided to give in and just enjoy all of the work that Sid was doing for him. Sid was the one that decided they should break things off.
- Enforced in the Rugrats episode "Driving Miss Angelica", where Angelica insists that Chuckie has to become her slave after she saves him from being run over. It gets turned against her at the end, when Chuckie saves her from being locked in the upstairs closet and Tommy and Chuckie convince her she has to become Chuckie's slave.
- Dinobot joins the Maximals through an odd combination of this and Defeat Means Friendship in Transformers: Beast Wars.
- In The Powerpuff Girls, Big Billy of the Gangreen Gang does this when the Girls save him from being run over by a subway train during a brawl. Things do not go well.
- Phineas and Ferb "The Bully Code", Baljeet saves Buford from choking, and thus according to the Bully Code Buford has to be Baljeet's slave. The obligatory musical number even Lampshades this as "a 70's sitcom cliché." It isn't until the end that Baljeet comes to realize the potential of ordering his sometimes friend/sometime tormentor/sometimes fanon love interest around.
- Donkey Kong Country, "Get A Life, Don't Save One!": Bluster Kong becomes DK's lackey after a life-saving experience. This doesn't go unnoticed by the series Big Bad King K. Rool, who comes under the paranoid impression that DK and Bluster are collaborating in some sort of plot against him. He subsequently has Bluster kidnapped in an effort to uncover whatever their "scheme" is, and in doing so inadvertently subverts the usual "master stages a disaster for the slave to save them from" stage of the trope. When Bluster doesn't show to save DK from a malfunctioning airplane, DK is forced to save Bluster once again from K. Rool's lair. Afterward, Bluster cuts off the debt himself, declaring that looking after DK's hide is more trouble than it's worth.
- The New Adventures of Winnie the Pooh: In the episode "My Hero," Piglet accidentally saves Tigger's life (or so Tigger thinks) when he lands in a shallow puddle where Tigger is "drowning" and splashes all the water out.

- The Recess episode "Copycat Kid" has Vince catch the baseball that was going to land on Mikey's face. Mikey keeps telling Vince that he saved his life and how much he admires him and wants to be like him, until finally he starts dressing like Vince and copying everything he does.
- Spoofed in the Jimmy Two-Shoes episode "Jimmy, Don't Be A Hero". Jimmy saves Lucius' life and gives a very casual, "think-nothing-of-it" kind of You Owe Me. Since no Heinous has ever owed anyone anything, Lucius desperately tries to pay him back for the rest of the episode with Jimmy being totally oblivious to it.
- The Rainbow Fish episode "Bodyguard" featured this: Rainbow saves the life of an older fish, who repays him by becoming his bodyguard. Unfortunately, he was a Knight Templar who does things like attack Rainbow's school friends when they're roughhousing in the schoolyard.

Mandy: Sam, you saved my life!Sam: I saved your hair.Mandy: My hair IS my life!
- An episode of The Amazing World of Gumball, titled "The Debt", revolves around this. Mr. Robinson "saves" Gumball (stops his slow-moving car when Gumball was too busy panicking to get out of its path) and Gumball decides he has to save Mr. Robinson in return, nearly killing him several times. Given Gumball had just shown to be a rather dedicated fan of Mr. Robinson, the whole thing may have just been an excuse to follow him around.
- SpongeBob SquarePants:
- Inverted in episode "Squidward the Unfriendly Ghost". SpongeBob and Patrick accidentally "kill" Squidward (actually a wax sculpture). Squidward comes out of the shower in a white bathrobe, covered in talcum powder, with a cloud of steam behind him, and is understandably angry about the mess they made of his sculpture ("Look what you did to me!") They mistake him for a ghost, and Squidward convinces them to pledge to serve him as payment for killing him.
- Another inversion occurs in the episode, "Naughty Naughtical Neighbors", where SpongeBob and Patrick stop being friends with each other due to a misunderstanding caused by Squidward.

Applejack: I know this code thing's important to you, but if somethin' like this comes up in the future, think maybe we can go back to my code, say "that's what friends do" and leave it at that? I promise I won't think of you as any less noble.Spike: Sounds good to me. But, maybe let's just try to avoid situations where one of us actually needs the other one to save their life?Applejack: You got yourself a deal.
