Follow the Leader/Fanfic

• The Land Before Time fanfiction. Considering that the series is set in a relatively limited environment (prehistoric times), whenever one writer does something different that gets respect, you can expect to see a lot of clones pop up. Such types include war stories, Time Travel stories, crossovers. Not that these fics are necessarily bad, but they tend to all come at once as trends, resulting in you finding that all new fanfics lately are centred around Chomper perhaps, while you were particularly hoping for something based more on the main five characters.
• Count the number of Pokémon fanfics which focus on an original trainer, who sleeps in on the morning when they're supposed to receive their first Pokémon, arrive at the lab only to find that all the usual starters are gone and instead get a completely different starter. Very often a rare and valuable Pokémon. Almost always an Eevee. Their goal is always to become a Pokémon master. To be fair, this is the purpose of the main series. The use of Eevee has generally slowed down, but OC journey fics are still the same even without Eevee.
  • There are sometimes fics that appear to be OC journeys at the start, then have a twist at the end that makes you think "what the heck..." until you re-read it. Then there are Pokémorph fics where a human turns into a Pokémon with no prior warning...
• At one time, there were far too many Cardcaptor Sakura fanfics that blatantly copied each other; as soon as someone comes up with something unique and interesting, a wave of people start ripping it off right down to the last joke and plot point.
• According to the Reunions Are a Bitch universe the Colonials of Battlestar Galactica were huge wankers before the Cylons kicked their collective arses to the curb, what with the whole starting a holy war against Earth thing. Naturally, the story was so popular that now there are dozens of different fics detailing the Colonials getting in over their heads while trying to Take Over the World. Most commonly these involve crossovers with Halo or Stargate SG-1, but other types do exist.
• Cassandra Claire's Very Secret Diaries for The Lord of the Rings fandom inspired several copycats in several fandoms, some acknowledging their inspiration coming from her. Even to this day, several years after their creation you still see some of her more infamous quotes scattered about fandom.
• Speaking of Cassandra Claire, The Draco Trilogy started (and named) the Draco in Leather Pants portrayal of Draco Malfoy. It also started or at least popularized some other Harry Potter fanfic clichés, like making Draco more sympathetic by portraying his father as an abusive bastard. The funny thing is, the vast majority of young fanfic writers who currently use these clichés have likely never heard of Cassandra Claire. They just copied them from earlier fanfics, who copied them from still earlier fanfics and so on, going all the way back to The Draco Trilogy. Cassandra Claire also popularized the idea of certain characters being "Magids", which are especially powerful wizards. When The Draco Trilogy was at its height, the concept of Magids was borrowed by numerous other Harry Potter fanfics, but now it's a Forgotten Trope.
• 75% of all Dragonball Z fanfiction starts with an alien spaceship crashing down on Earth, and ends with a character using a new form of Super Saiyan to beat them. It will also be set during the 3 months before the Androids, the 7 years before Cell or the 10 years after Buu. Other common elements include Vegeta or Broly getting possessed by Babidi, Buu or Cell absorbing someone new or each other, Saiyans inexplicitly growing back their tails, Bardock being rewritten as an honourable anti-hero and Future Trunks travelling to New Namek to use the Dragon Balls there.
• The current trend among people who write Troll Fics (or who just want a lot of reviews and attention and don't care about the quality of their work) seems to be to copy My Immortal's format, issues with spelling, My Chemical Romance references, and Goth Sue main character.
• For a while, there were Gundam Seed fanfics following the lead of Brothers in Arms by having a Defector From Decadence join the crew of the Archangel at the series' start and cause changes to the canon from there.
• In 2001, Potato Salad of Fanfiction.net wrote Ask Sonic (and other associated characters), which had reviewers sending questions through reviews or e-mail and having Sonic the Hedgehog and the rest of the cast answering them as fan mail. It became very popular and soon numerous Ask Fics began to show up on Fanfiction.net until it and other interactive fanfiction were banned from the site.
  • Oh, they're still there. The Axis Powers Hetalia section of Fanfiction.net is currently being saturated with them...
    • Yes. 'Tis very annoying, especially since Hetalia is based on history, much of which would make a great story concerning these characters, if written well
• Nearly every Harry Potter story in which Harry is betrayed and sentenced to Azkaban follows the exact same template: Most of his friends instantly morph into Complete Monsters and repeatedly Kick the Dog, and instead of dying or going insane, Harry becomes a God Mode Sue in prison and later wipes out Voldemort and all his Death Eaters with a single attack. Depending on the author, he then proceeds to kill everyone else as well or spend the rest of the story brooding with those who stuck by him (usually Snape, Neville, Luna, and a few others), while those who betrayed him plead for his forgiveness.
• Eiga Sentai Scanranger was created to let its author complain about Power Rangers, yet seems to have taken quite a few cues from the imported show. Interesting is one scene where the blue ranger flies off the handle at the changes made in Power Rangers Dino Thunder, but no mention is made of how the character concepts for Mesogog and Elsa are almost identical to two villains from Scanranger. The Big Bad is a former colleague of the team's mentor sharing his body with an evil presence, and the lone female villain wears black leather and spies on the heroes via her job at their school (Scanranger did it first).
• NGE: Nobody Dies have spawned a whoppingly large Expanded Universe around it. The author of the original even made some of these canon, like Ichi's Birthday Party, The Story of NERV-Alaska and The Kei Files.
• This is the reason why Total Drama Island fanfiction is known almost solely for its (in)famous Starring You fanfics.
  • Many fics can be considered snowclones of Total Drama Comeback.
• The Mass Effect section of fanfiction.net was known for having relatively few self-inserts. Enter Herr Wozzeck with his self-insert Mass Vexations. After that, a great number of self-inserts began to show up around the website, with varying results.
• Family Guy fanfiction was never too great, until a guy named Malcolm Fox wrote a story named Meg's Boyfriend. The story was funny, amusing, had a varied cast of characters, hilarious OCs, great plots, and it emulated the show's essence like no other fanfic. Many other authors began to write similar stories, in an attempt to achieve Malcolm's success.
• One time, a fanfic writer called Roxius wrote a Crack Fic titled You Got LuluRolled. This spawned many similar Crack Fics in several different fandoms, not all of them titled with some variation of "You Got [Character Name] Rolled!" Most of the imitations are actually derived from superstarultra's Haruhi version, You Got Haruhi Rolled, which is generally considered superior to its inspiration.
• Quite a few Familiar Of Zero fanfics have been made with the premise of 'What if X got summoned instead of Saito?' All of them were complete crap, at least until gabrielblessing's The Hill of Swords came along with its lauded execution of the concept. One well-timed Plot Bunny thread later, SpaceBattles.com's Creative Writing forum was flooded with copycats. A fair few of these, such as Unfamiliar, Zero Shock and The Shadow of Zero match or exceed the original in quality.
• Since the My Little Pony Friendship Is Magic fanfic Progress became popular, it has become commonplace for other writers to portray Princess Luna with a Companion Cube abacus.
  • Same with Cupcakes. Ever since it became popular, there have been many other My Little Pony: Friendship Is Magic dark fics set out to copy it's success.
• An interesting trend has popped up amid the Mahou Sensei Negima fanfic authors. After Shadow Crystal Mage popularized the idea of crossing over Negima with Magical Girl Lyrical Nanoha, a few other authors have taken up the mantle. Currently, Mage and two others are writing stories in which negi is sent to Uminari as a teacher for Nanoha after the events of A's. Ironically, one of the copycats, Zephyr-Fiction's Equal And Opposite Attractions, has garnered the most press. Mainly this is because Mage has many more projects on his plate.
• Common Itachi/Sakura plots in Naruto fic involve Sakura running off to get Sasuke back from Orochimaru's clutches, and getting captured/used as bait for Naruto by Itachi. Many cite Metamorphosis as inspiration or influence.
• Everybody wants to write about what Sherlock Holmes did during his Great Hiatus (the three-year period during which he faked his death), right? It's been the subject of numerous pastiches and online fics. Aragonite a.k.a Marcia Wilson has made the argument that none of these stories, however, deal with Dr. Watson, Inspector Lestrade, and Scotland Yard, and the adventures they must have been having in that time period. So she wrote her own series, which she plans to convert into self-published books. Thus far, only one other Fan Girl has taken up the torch, so to speak, but that's not the only thing Aragonite started. She was arguably the first Fanfic author to give any serious depth to the men of Scotland Yard and use them as the protagonists, rather than using Holmes or Watson. She also bestowed the name Geoffrey upon Inspector G. Lestrade, and that name has gained popularity among both the canon and Sherlock branches of the fandom.
  • The Fanfic series following in Aragonite's footsteps is the Deliver Us from Evil Series. The name "Geoffrey" is also used.
  • Another fic on the wiki to utilize the name "Geoffrey" is A Study in Regret. Incidentally, the author was inspired by the Deliver Us from Evil Series and dedicated the fic to that author.
• While he certainly wasn't the first to write a Self-Insert Fic where the Author Avatar was horrendously super-powered, Darren "Twister" Steffler's Twisted Path may well have been the first to send its main character merrily bouncing from fictional setting to fictional setting (almost all of them Anime series) within a larger Multiverse. It made a major impact on mid- to late-1990s anime fanfiction, and inspired numerous imitators and tributes, including The Bubblegum Zone and Drunkard's Walk.
