** Crocodile's plans hit an unfortunate (for him) snag with the presence of [[spoiler: Mei Hatsume, who has invented desalination machines to counter his artificial water shortage. He can't even sabotage them, because she just fixes them each time, and she keeps accidentally blowing up his assassins when he sends them to try and kill her!]]
** Due to the Government offering [[spoiler:Luffy]] the Warlord position left after Crocodile's death, [[spoiler:Robin joining the Straw Hats means she's now untouchable.]] Sengoku is furious on realizing the mistake, whereas his old friend Garp however, finds it predictably hilarious and his own way of getting back at the Elder Stars for screwing up his own plan for getting Luffy as a Warlord

* UnusuallyUninterestingSight: When Shanks calls his old Crewmate Buggy to get info about why Luffy accepted a position as Warlord, Alvida reacts with shock at how Buggy talks to his old Crewmate whereas Mohji and Buggy don't see anything wrong with it.

* AdaptationalKarma: At the end of the Arlong Park arc, Garp confronts Nezumi with the knowledge that he's been working with the pirates.

* BrickJoke: When Izuku and Ochako finally get a RelationshipUpgrade, Setsuna hopes they remember to use condoms. Luffy what a condom is, leaving Setsuna horrified at the idea that the One Piece world doesn't have birth control. Later after Izuku and Ochako have their first date, Nami says she made sure they had a condom to use, and explains that their world ''does'' have birth control. Luffy's just an idiot.

''[[https://archiveofourown.org/works/30726698/chapters/75832676 Pirate Heroes]]'' is a ''Manga/MyHeroAcademia'' and ''Manga/OnePiece'' crossover by [[https://archiveofourown.org/users/The_Mad_Mystic/pseuds/The_Mad_Mystic The_Mad_Mystic]] on Website/ArchiveOfOurOwn. In it, Izuku dies after successfuly saving Eri from Overhaul, only to meet a robotic entity called Jeroth, who offers to send him to the world of One Piece, along with six others, figuring that that world could use a few new heroes, and return them to their own world at the exact moment of their deaths once their journey is complete, keeping any new powers be they Devil Fruit or otherwise, upon their return. Accepting, Izuku is then sent to the East Blue, where he soon runs into Luffy during his fight with the Alvida Pirates...

* DropTheHammer: Ochako ends up taking a hammer (it also has a spear function, but she doesn't really use it) from Don Krieg that [[HavingABlast makes an explosion whenever it impacts a target, the strength of the explosion dependent on the strength of the impact]]. In the hands of Ochako, who can render its incredible mass completely weightless, thus limiting the strength of the explosion to how hard [[AmazonianBeauty she]] can swing it...

* TheRedBaron: The Straw Hat Pirates pick up a few of these when they get their bounty posters. For example, Izuku becomes known as "The Eldritch" (later upgraded to "Eldritch Nightmare"), while Ochako goes by "Valkyrie".

** Ochako is really sweet, kind, and passionate. If you make the mistake of thinking that makes her weak, she'll correct your assumption by throwing you around with her Gunhead Martial Arts, hitting you with her explosive hammer or straight out sending you flying with her Quirk, and like Izuku is developing a thirst for battle.

** [[spoiler:In canon, Going Merry dies from the collective strain of her Grand Line journey culminating in her falling apart after the escape from Enies Lobby. Here, Enel destroys her during the Skypiea arc]].

* ForWantOfANail: [[spoiler:Doflamingo killing Bellamy's crew results in him joining up with Buggy]].

* LaserGuidedKarma: [[spoiler:Enel meets his downfall at the hands of the Straw Hats as a direct result of deliberately provoking them with the destruction of their beloved ship.]]
