History FandomSpecificPlot / BuffyTheVampireSlayer

** 3) [[HesJustHiding A post-season six story in which Tara comes back from the dead.]] [[note]]This one has its basis in a proposed plot for Season 7 in which Buffy wishes Tara back from the dead.[[/note]]

* Some OC Slayer wishing to be left alone (or making a pretty good work by herself) up until Buffy arrives into her life and [[MeetTheNewBoss acts in no way different from how the Watchers' Council treated her]], the only real differences being [[BuffySpeak the valley-girl speech pattern]] and [[MightMakesRight the capacity to get physical with the Slayer if she must]] (although pretty often it is more of a "will"). Sometimes [[AccusationFic another character will point out her hypocrisy]], with a response of "well, I'm ''the'' Slayer, so if I do it, I guess it has to be in the right".

* Rewrites of early episodes (usually Season 1) to include an OC, or in rarer cases a canon character who wasn't present in the original. With seasons 1-4, a subtrope is [[CosmicRetcon the altered memories of the cast that include Dawn]]. However, using Dawn for this purpose invokes InSpiteOfANail, because she wasn't ''really'' there.

** Book is (or was) a Watcher. {{Jossed}}. Not that it needed to be...

* What might be termed the "Slayer Speculation Fic", in which the famous, strong n unemale character of the author's choice from another fandom is called as a Slayer by Willow's spell in the series finale.

** [[https://www.tthfanfic.org/index.php?/ Twisting The Hellmouth]], a fanfic site mainly devoted to crossover fics between BTVS and other properties, introduced an unusual sub-genre, "Ship of the Line" stories. In a SOTL story, Xander will wear a costume of a spaceship commander ([[Series/StarTrekTheOriginalSeries Captain Kirk]], [[Film/StarWars HanSolo]], [[Series/{{Firefly}} Mal Reynolds]]) and after the events of "Halloween" not only will he have the memories of the character he dressed up as, he will have access to his character's ship (U.S.S. Enterprise, Millennium Falcon, Serenity).

* What might be termed the "Slayer Speculation Fic", in which the famous, strong female character of the author's choice from another fandom is called as a Slayer by Willow's spell in the series finale.

* The (in)famous ''Yet Another Halloween Fic'' sub-genre of fanfiction, in which the characters choose different outfits for [[Recap/BuffyTheVampireSlayerS2E6Halloween the fateful Halloween]] when Ethan Rayne [[BecomingTheCostume turned everyone into their costumes]]. Invariably, these will be the costumes of recognizable characters, particularly from anime. Xander and Dawn are especially popular recipients of this, Xander because his soldier costume was both fairly generic and left him with a degree of BrainwashResidue in the form of military training (meaning that a different costume will leave elements of that character imprinted on him), and Dawn because she was {{Cosmic Retcon}}ned into existence in season five and therefore wasn't in the HalloweenEpisode (meaning that it's fun to speculate what she might have worn).

** Xander still having a portion of his various possessions to become an EmpoweredBadassNormal.

** 2) [[FixFic Rewrite season six so that Tara doesn't die.]]

** Mal will be mistaken for Caleb. Zoe and Jayne's resemblance to [[Series/{{Angel}} Jasmine and Hamilton]] may also be brought up, but this occurs less frequently.

** With seasons 1-4, a subtrope is [[CosmicRetcon the altered memories of the cast that include Dawn]]. However, using Dawn for this purpose invokes InSpiteOfANail, because she wasn't ''really'' there.

* Road Trip stories that show much more happened on Xander's offscreen road trip than just his car breaking down and him stripping to pay for repairs. Often used to introduce crossovers.
** Alternatively, someone joining Xander on his road trip. Cordelia being one of the more common ones.

** It's to be mentioned that, even when it is not the whole (or the most important) part of the plot, there are ''many'' Buffy fanfiction stories where a character fires off a lengthy WhatTheHellHero speech at what the author perceives were serious flaws of the character or the canon Buffy series plot.

* Buffy takes the "General" part of her role during Season Seven to its more literal extreme: [[{{Handwave}} in one way or another]], the military starts to employ Slayers for anti-supernatural Spec-Ops work. Buffy is either just the first, the leader, or pretty much TheOnlyOne. Crossover with military-themed shows (like the Franchise/StargateVerse or ''Series/{{NCIS}}'') is pretty probable under these circumstances.

* The organization of a "Slayer Academy" post-Season Seven. Varying from military-style boot camp to "sorority for superpowered girls" to (sometimes literally) a [[Franchise/HarryPotter Hogwarts]]-style experience.

* Buffy is sent back in time to circa 1880, and meets either human William Pratt or vampire William the Bloody. Almost always a straight Buffy/Spike pairing, though the plot can be used to set up Buffy/Angelus as well. [[OneTrueThreesome Or both.]]

** 3) [[HesJustHiding A post-season six story in which Tara comes back from the dead.]]
* ''Buffy'' and ''{{Series/Firefly}}'' is such a CommonCrossover that such stories have their own tropes (and considering the amount of 'Verse slang that pops up in the future-Slayer comic ''Fray'', some fans wonder when Joss is going to declare that world to be Earth-That-Was and get it over with). For example:

* Rewrites of season 1-4 episodes to include Dawn, or specifically [[CosmicRetcon the altered memories of the cast that include Dawn]].
* Rewrite of season 6 to bring Faith back after Buffy's death at the end of season 5. Usually serves to set up a Buffy/Faith pairing after Buffy's resurrection, but there are other pairings and directions that the plot can take.

* Someone other than Xander being possessed by the Primal Hyena.

** Rarely will more than one or two of the Scooby Gang feature, and it's usually Xander or Willow transported to the future/an alternate dimension via magical portal or suspended animation.

** Xander is an enormous BadassNormal, since he only has normal humans to fight, and has spent his life surviving against creatures at least twice as fast and strong as he is.

** Rewrites of season 1-4 episodes to include Dawn, or specifically [[CosmicRetcon the altered memories of the cast that include Dawn]].
