*** Almost every Picard/Crusher author has written an "epilogue" or fix-it fic for the Season 7 episode "Attachments," which contained major ShipTease between the two, but ended in a way that many shippers found unsatisfying.

** If Deanna Troi is featured in a ''Series/StarTrekTheNextGeneration'' fanfic, she'll usually either be whiny and/or disliked by Picard and the rest of the crew, a parody of herself with her love for chocolate exaggerated (sometimes due to PMS or pregnancy), or described poetically, only to have her die.
** Data experiencing some "human" thing for the first time-- shipping stories will have it be romantic love, while comedies will have it be anything, from laughter to even catching a cold.

* For South of Nowhere, the most common theme in fanfiction is actually AU, using the characters but not really following the show's storyline.

* ''Series/KamenRider''

* With The Vampire Diaries, Salvatore Sister stories are quite common where Stefan and Damon have a female relative, usually a sister but not always, accompanying them, creating a similar dynamic to Klaus, Elijah and Rebekah.

** Someone else other than Sara being on the ''Gambit'' with Oliver when it sank. The most common substitution is Laurel, but others like Tommy, Barry and Thea have been used as well. They are also the stories where Sara is the one who makes it to the island instead.

* A very popular idea in ''Series/TedLasso'' fic, particularly after the finale, is of Henry and Michelle moving to the UK so Ted doesn't have to choose between being in his son's life and coaching AFC Richmond (and usually whichever love interest they pair him off with).

* A very popular idea in ''Series/TedLasso'' fic, particularly after the finale, is of Henry and Michelle moving to the UK so Ted doesn't have to choose between being in his son's life and coaching Richmond FC (and usually whichever love interest they pair him off with).

** The number of stories where Laurel survives past her canonical death and/or is allowed more time to properly develop into being the Black Canary are so many that they're almost a fandom of their own. Most of those stories also see her somehow awaken the Canary Cry (usually by being present during the Particle Accelerator Explosion or by having her metagene awakened by some kind of stressful event) as a symptom of that.

** After Mia Smoak, the canon daughter of Oliver and Felicity, was introduced, there was an increase in stories where she was revealed to be the daughter of [[FanPreferredCouple Oliver and Sara]] instead, mostly because Mia was still liked in spite of her parents' ship being [[AbandonShipping the most divisive in the entire Arrowverse fandom]] and because the actress resembled Caity Loitz more than Emily Bett Rickards.

** Fic dealing with Don't Ask, Don't Tell is common in slash.

* ''Series/{{Smallville}}'' fan fics are sometimes known for mixing in elements from the films and the Franchise/{{DCAU}}, occasionally to get rid of some unsavory trait, ComicBook/GreenArrow being [[spoiler:a killer]], for example.

** The ''Dino Thunder'' episode "Fighting Spirit" has Tommy facing a BattleInTheCenterOfTheMind with his previous Ranger forms. A lot of fans such as [[WebVideo/HistoryOfPowerRangers Linkara]] have some interesting takes on what this says about how being a Ranger for so long has affected Tommy's mental state.

** Someone else other than Sara being on the ''Gambit'' with Oliver when it sank. The most common substitution is Laurel, but others like Tommy, Barry and Thea have been used as well.

** Wednesday visiting Enid in San Francisco is a fairly popular plot. These almost always have Wednesday being appalled by Enid's family treating her horribly and having Enid move in with the Addams Family.

** Fanfics where Principal Weems is revealed to be alive are very popular. This mainly comes in the form of simply rewriting the story so her death scene never happens or revealing that she takes her death with the reason varying.
