One fine day, [[Film/IronMan Pepper Potts]] meets with billionaire [[Literature/FiftyShadesOfGrey Christian Grey]] to discuss business arrangements between him and Stark Industries. When she trips coming into his office, he becomes smitten and absolutely certain she's the perfect submissive for him. Unfortunately, Pepper has no interest at all in any sort of a relationship with him. He continues to pursue her in [[StalkingIsLove various disturbing ways]]. She calls in Natasha Romanov and Clint Barton for assistance. HilarityEnsues.

''[[https://www.fanfiction.net/s/8753648/1/Christian-Grey-Vs-Pepper-Potts Christian Grey Vs Pepper Potts]]'' is a crossover fanfiction by Imarra Pendaran. Initially written to show what would happen [[TakeThat if Christian Grey pursued an actual independent woman]], it goes on to span much of the MarvelCinematicUniverse as well as several other Marvel comic book titles as the Avengers is formed properly, several couples get married, and Christian Grey continues to cause far more trouble than anyone suspected.

----

* ActionGirl: Natasha Romanov, She-Hulk, and Rogue, naturally.
* AdultFear: While Christian's misogyny is generally PlayedForLaughs, there are several times when his intentions towards several women are truly alarming. [[spoiler:Near the end of the story he has a meltdown while it's just him, [[BadassNormal Pepper]], and a heavily-pregnant Natasha, with the heavy implication that he'd have killed both women if they hadn't killed him first.]]
* {{Antidisestablishmentarianism}}: [[spoiler:This is the safe word Christian is given while being worked over by the CFAASPBDDSSM[[note]]the Council for Appropriate and Safe Practice of Bondage and Discipline, Dominance and Submission, and Sadism and Mascochism[[/note]].]]
* ButICantBePregnant: [[spoiler:Natasha and Clint have this reaction towards Natasha's pregnancy, the former because she was on SHIELD-issued birth control (which she found out was being recalled) and the latter because of a sperm count so low he thought he'd never have children).]]
* DoubleStandardRapeFemaleOnMale: Averted. When [[spoiler:Rogue controlled by Christian's personality]] tries to molest Clint Barton, it's written as just as traumatizing as any of the times Christian tried to do the same to various female characters. Also, while everyone considers Christian's actions reprehensible, Rogue is horrified at his [[QuestionableConsent relationship]] with Mrs. Robinson and understands at least how it led to his intense desire for control.
* GoodGirlsAvoidAbortion: [[spoiler:Natasha is on the fence as to whether or not to go through with her pregnancy, mainly because she's still haunted by her first child, who was stillborn. After she finds out just how miraculous it was that she or Hawkeye managed to conceive a child and after coming to terms with what happened in her past, she decides to go through with it.]]
* GroinAttack: Happens to Christian so often it ends up being a RunningGag.
* HappilyMarried: Pepper and Tony eventually, as well as [[spoiler:Rogue and Gambit]].
* ItHasBeenAnHonor: Clint and Remy give this to each other, [[spoiler:when they believe they're going to die in a lab explosion.]]
* TheMentallyDisturbed: Mostly played for laughs but Christian in all his disturbing glory.
* PregnantBadass: [[spoiler:Natasha]]
* RealityEnsues: In a sense. The entire point of the fanfiction was how things from the ''Literature/FiftyShadesOfGrey'' series would have gone if an actual independent woman was in Ana's place.
* SlutShaming: Ana engages in this, accusing ''Pepper'' of being the one at fault for Christian pursuing her, when he stalked her and insisted they were destined just because she tripped from a broken heel.
--> "Are you serious?" Rogue asked, voice laced with disbelief. "You're blaming an attempted-rape victim for her attacker's actions? Bless your heart, but you're dumber than a two-headed horse with both heads stuck in a barbed wire fence."
* TakeThat: To ''Literature/FiftyShadesOfGrey'' as a whole. A good many situations are replicated (tripping in front of Christian, attending a charity event with his family, being taken to a hotel room by him while incredibly drunk, etc.), and have the female characters in those positions point out exactly how creepy and/or illegal those actions are.
* TheCameo: Besides the main heroes, there are cameos from the X-men, Scarlet Witch, and Squirrel Girl.
* TooDumbToFool: To an extent, Christian. The Avengers are stunned that such a spoiled idiot manages to continue to elude them, until they realize that he's essentially able to do so ''because'' he's a spoiled idiot, and their tactics are meant for tracking down criminal masterminds and evil geniuses.
* TooDumbToLive: Yes, Christian. Just [[spoiler:kidnap and threaten She-Hulk's assistant]]. That's certainly not going to end badly for you!
* {{Trigger}}: The protagonists eventually notice that women tripping in front of Christian triggers him to develop a deep obsession towards them and insist that they're in love.
* ViolentlyProtectiveGirlfriend: While technically not his girlfriend[[note]][[WhamEpisode Before chapter 28 anyway]][[/note]], Romanov goes ballistic when she realizes Barton is in danger.
