History DealWithTheDevil / FanFic

* ''Fanfic/{{Equestrylvania}}'': 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.

** Lucius allying with Gravemoss is presented in this fashion, since it is patently obvious that Lucius has, at first, absolutely ''no idea'' how [[CompleteMonster bad]] [[OmnicidalManiac Gravemoss]] actually is and it is heavily implied that Gravemoss is going to turn on him the moment he gets bored. To confuse matters slightly, Lucius procures [[SealedEvilInACan the]] [[ArtefactOfDoom Darkhold]] for him in exchange for allegiance, meaning that technically, both do deals with the devil.

** Venus also prayed to Maledict for the power to protect her people from Tsali. [[BodyHorror He answered]], although [[AndIMustScream not in the way she expected]].

* ''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.

** Venus also prayed to Maledict for the power to protect her people from Tsali. [[BodyHorror He answered]].

** Tsali vowed to serve and follow Maledict if he would help the fox get revenge on the Seedrians. Maledict blessed him and saved his life in response [[and secretly altered his brain]].
** Venus also prayed to Maledict for the power to protect her people from Tsali. He answered.

* ''FanFic/SonicXDarkChaos'' has quite a few from [[{{Satan Lord Maledict]].

'''Calvin:''' [[ItSeemedLikeAGoodIdeaAtTheTime Well, it seemed like a good offer!]]

* ''[[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 yer]]), 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/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.

* ''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.

* ''[[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 yer]]), to spare his butler Alfred.

** [[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.]]

* ''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/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.

* 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 ''[[CompleteMonster 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.
