* Occurs twice in ''Fanfic/TheLionKingAdventures'':
** In ''Miss the Girl'', Moto makes one of these with Hago in exchange for appearing irresistible to Nala. What does Hago want in return? [[spoiler: Simba.]]
** Zazu makes one with Death in ''Darkness Falls'' [[spoiler: in order to save his father from being executed by King Ahadi. However, [[LoopholeAbuse Death just kills his father personally, as opposed to King Ahadi doing it.]]]]
* In ''Fanfic/KeepersOfTheElements'', [[spoiler:Courtney]] makes one of these with [[BigBad Radcliffe]] in exchange for [[CastingAShadow powers]] of her own so she can get revenge on most of the Keepers, but [[spoiler:[[TheLeader Gwen]]]] in particular.
* ''FanFic/InnerDemons'' has a couple of metaphorical examples. First off, Rarity outright refers to [[TheDragon Trixie]] willingly agreeing to serve [[BigBad Queen!]][[FaceHeelTurn Twilight]] in her evil in exchange for power as selling her soul. Meanwhile, [[spoiler: Sweetie Belle and Scootaloo]] pledging loyalty to Queen!Twilight after she [[spoiler: [[PlotRelevantAgeUp ages them up]] and gives them their Cutie Marks]] fits the thematics a little better.
* The ''FanFic/PonyPOVSeries'' has [[spoiler: Diamond Tiara agreeing to free [[SealedEvilInACan Discord]] in exchange for him curing her mother's insanity (though to be fair, she didn't know who she was dealing with until the very end). Surprisingly, Discord actually keeps up his end of the bargain, but it seems that since he swore on [[EldritchAbomination His Parents]], he didn't have much choice in the matter -- and in any case, he managed to completely [[BreakTheCutie corrupt Diamond and break her to his will]] in the process, so he still screwed her over.]]
* PlayedForLaughs in ''[[Fanfic/EbonyDarknessDementiaRavenWayVsCanon Sapphire Eleanor Rose Suzette de Mont vs. Canon]]''. Charlie rather [[BreadEggsMilkSquick casually]] mentions doing this. Multiple times. According to another character, making deals with higher powers in general is fairly commonplace.
* Since the first generation cyborgs escaped their clutches early on in ''FanFic/YoungOffender'', [[Manga/{{Cyborg 009}} the Black Ghost organization]] gets clever when it comes to the second generation. Instead of simply kidnapping people to turn into cyborgs, they find ways to get them into their debt first; that way, if they think of backing out, well... ShameIfSomethingHappened.
* ''FanFic/MyLittleCastlevania'': When [[TheCreepyUndertaker Dirt Nap]] is recruited by Dracula's minions, they offer him the power to [[ThenLetMeBeEvil take revenge on Ponyville for shunning him]] by fusing him with the demon [[PlayingWithFire Aguni]]. Notably, they warn him that it will cost him his soul, but he doesn't care and accepts.
* In the finale of ''Fanfic/ChildrenOfTime'', [[TheChessmaster Professor]] [[ManipulativeBastard Moriarty]] offers Literature/SherlockHolmes a SadisticChoice: Holmes's soul, or Watson's slow, tortured death. And goes as far as to have ''Watson's bad arm broken''. Horrified and desperate, [[FaceHeelTurn Holmes agrees]].
** Much later on, things seem to have been set right... until Moriarty kidnaps [[WesternAnimation/SherlockHolmesInTheTwentySecondCentury Beth Lestrade]] and tells her he's about to kill Holmes, Watson, and [[Series/DoctorWho the Doctor]]. Beth frantically begs him not to and offers herself as a willing slave in return for their life and liberty -- a deal Moriarty agrees to, almost certainly understanding how much it would hurt Holmes.
* FanFic/TheNuptialverse: Chrysalis was once a normal pegasus, until Discord offered her the power of the three pony races in exchange for destroying the Energy of Friendship (the fires that destroyed the Windigos) to allow him to enter Equestria. Notably, Chrysalis thought that he was going to turn her into an alicorn; [[RewardedAsATraitorDeserves instead]], he decided it would be [[JackassGenie funnier]] to make her a changeling.
* ''FanFic/{{Horseshoes and Hand Grenades}}'', has the [[EldritchAbomination Serpents]] imposing deals in order to resurrect the people they want to contract with. For example, [[spoiler: Shun, having been killed by Ryusei, makes a contract with Vasuki but he must live till the Earth's destruction, thus never being able to be with the people he loves. Shotaro gains one with Damballa to never be hurt again, but has his body transformed into one of a CreepyDoll and his sanity shattered along with it.]]
* ''Fanfic/GettingBackOnYourHooves'' has the Diamond Dogs agree to help [[BigBad Checker Monarch]] ruin Trixie's life in exchange for a huge payment of gems. They quickly find out [[EvilerThanThou Checker was somepony they shouldn't have messed with]] and are [[EvenEvilHasStandards horrified by the methods she uses]], but can't back out or she'll turn their mine into a parking lot, with them still in it. [[spoiler:In the end they get out of it by helping the Mane Six trick her into an EngineeredPublicConfession.]]
** [[spoiler:Helping Hoof made one with Checker. He never earned his Cutie Mark and was being hounded by his {{Abusive Parent|s}} Iron Hoof for it. So he agreed to work for Checker in exchange for her helping him fake earning a Cutie Mark and a job. Checker keeps her end of the deal, but Helping Hoof was reduced to little more than her puppet to torture as she pleases. In the end he gets free by finally helping expose her and turning himself in to the guard.]]
* ''[[http://www.fanfiction.net/s/9510186/1/Terminal-Justice Terminal Justice]]'' has Batman beg Mr. Black, who the League believes to be [[TheGrimReaper Death]] ([[spoiler:they're right, he just doesn't know it yet]]), to spare his butler Alfred. Mr. Black uses his fragment of a philosopher's stone to give Alfred roughly fifteen more years of life. He then goes on to kill Joker, Two-face, Scarecrow, and Riddler, seemingly as payment.
* ''FanFic/{{Hivefled}}''; the Grand Highblood and the Condesce have a hobby involving inflicting ColdBloodedTorture on teenagers, including their own descendant, and [[SadisticChoice threatening the victims' friends]] until they sign over their souls. The ghosts of the two thousand plus victims are bound to a pocket dimension known as the Trap, until the Grand Highblood dies and hands them over to his patron spirit, who is apparently like him only more so.
* ''FanFic/DiariesOfAMadman'': Discord forcing Celestia into one with him kickstarts the plot of the story, and he later forces several other characters into such deals to suit his own ends.
* Discussed in ''Fanfic/AttackOfTheTeacherCreature'':
--> '''Hobbes:''' I'll pass, thank you. I'm not interested in that stuff. I didn't sell my soul to the devil.\\
'''Calvin:''' Neither have I.\\
'''Hobbes:''' [[NoodleIncident Yes, but you nearly did once.]]\\
'''Calvin:''' [[ItSeemedLikeAGoodIdeaAtTheTime Well, it seemed like a good offer!]]
* ''FanFic/MegaManRecut'' has Dr. Light accepting funding from Senator King, who is in with the Syndicate. He is not aware of this.
* The ''Manga/AttackOnTitan'' fic [[https://www.fanfiction.net/s/10156375/1/My-Child My Child]] centers around a [[FauxAffablyEvil demon]] named [[OriginalCharacter Xaphan]] trying to get Levi to sell his soul to him, using every method he can to persuade him. However, Levi wants none of it and basically tells Xaphan to fuck off every time. [[spoiler: He does eventually end up making a deal with the demon to save his son from dying in childbirth, and the story ends with him being tortured in Hell for it.]]
* ''FanFic/SonicXDarkChaos'' has quite a few from [[{{Satan}} Lord Maledict]].
** Tsali vowed to serve and follow Maledict if he would help the fox get revenge on the Seedrians. The Devil blessed him and saved his life in response [[spoiler: and secretly altered his brain so he would never feel remorse]].
** Venus also prayed to Maledict for the power to protect her people from Tsali. [[BodyHorror He answered]].
* ''FanFic/BadFutureCrusaders'': Despite everything that [[FallenHero Twilight Sparkle's]] actions cost her, Sweetie Belle still cut a deal with her new government in order to secure her own position as leader of the Diamond Dogs gems mined by the Dogs were used to fund the creation of Environment Equestria, who in turn assured that the valley where the Diamond Dogs live always gets the right weather to ensure they can sustain an actual society.
