Most of the fanfiction for ''OnePiece'' seem to have the same few plots over and over again:
----
* A retelling of the canon story, but with a new OC added. Typically will follow TheStationsOfTheCanon almost to a T and peter out sometime before the Alabasta arc.
* A new generation of pirates story set X years after the death of Luffy, the 2nd Pirate King. Typically will solicit readers to submit their OCs to fill up positions on the crew and as rivals/enemies.
* An OC from the real world gets pulled into the One Piece world and makes friends with the Straw Hats, Whitebeard or the Heart Pirates. Typically later falls in love with Luffy/Zoro, Ace, or Trafalgar Law.
** ''Fanfic/MarieDSuesseAndTheMysteryNewPirateAge'' is a DeconstructionFic of what would happen if someone fell into the OnePiece world.
* Sanji/Luffy/Nami getting sick and Zoro taking care of him/her. Instead of, you know, the actual ''doctor'', Chopper. And yes, it always seems to be Zoro.
** It probably has a lot to do with Zoro's position as the "[[BigBrotherInstinct eldest brother]]" amongst the TrueCompanions.
* Any member of the crew, or even the whole crew, find out the secret behind why Sanji keeps his left eye covered. Or sometimes, just Sanji reflecting on it and no one finds out. Obviously, more common [[spoiler:Pre-Time Skip]], as after the [[spoiler:Time Skip, Sanji covers his right eye and leaves his left visible,]] thereby proving pretty much all previous guesses wrong.
* Luffy, sometimes Ace and Sabo too, is taken in and raised by whitebeard's crew.
* Fem!Luffy out to prove that [[GirlsNeedRoleModels women can become pirate king/queen too]]. Expect [[ThisCannotBe over-the-top stunned reactions]] from her [[StrawMisogynist opponents]] when they're [[IWasBeatenByAGirl easily defeated]]. She will almost always be paired with either Zoro or Law, though Ace and even Shanks! have also been seen. They will initially find her annoying, [[ManicPixieDreamGirl but the tough males will soon be won over]] by her [[AmazonChaser show of physical strength]] and childish (though they interpret it as [[TheIngenue innocent]]) behaviour. She is, of course, [[WomenAreWiser smarter than her canon counterpart]], and dazzles her designated loveinterest when she shows that she's [[ObfuscatingStupidity not as dumb as she acts]]. Her characterization is confusing, but everything becomes much clearer once you just call her a [[MarySue Mary Sue]].
