Fanfic Fuel in Western Animation.

Shows/franchises with their own pages:

• Infinity Train
• My Little Pony: Friendship Is Magic

---

• Adventure Time:
  • The history between Marceline and Simon Petrikov. As the show went on, it's clear that Simon's morals and ethics were a heavy influence on a young Marceline, serving as a Parental Substitute. Fans enjoy exploring their bond, coming up with stories that either take place in the immediate aftermath of the Mushroom War (which is this trope in of itself) or take place after Simon is returned to normal in present-day Ooo, to nothing of the various AU fics where he at least makes an appearance as a mentor figure.
  • For that matter, the relationship between Simon and Betty seems to get a lot of attention.
• In the Aladdin: The Series episode "Eye of the Beholder", it's revealed that Fasir and Mirage were once in love. What was their past like?
• The final episode of Amphibia drops multiple ones:
  • Ivy mentions discovery of a new continent "untouched by frog, newt or toad hands", with at least 3 characters, Sprig, Ivy and Grime eager to explore it. It's a perfect setup for all kinds of crossovers, especially that one.
  • Anne, Sasha's and Marcy's lives after the series' finale, either leading towards the Where Are They Now ending or going forward.
  • The fact that Anne, upon dying at age 91, will become the replacement of the omnipotent Guardian of the Multiverse, basically becoming a god.
• Avatar: The Last Airbender:
  • The fate of Ursa. The show left a few other minor plot threads hanging, but that's the one that really got everyone upset, and speculating. It was resolved in Avatar: The Last Airbender - The Search, though it divided fans and critics.
  • And, you know, a century-long war, with plenty of rich, undeveloped ground for exciting battles and stuff. And one thousand Avatars in the history of the world, too.
  • The Sequel Series, The Legend of Korra, is filled to the brim with potential fanfic hooks. Not only is the show set eight decades after Avatar, but there are also several smaller time skips within the show itself, including a whopping 3-year gap between Books Three and Four. Also, Korra's comparatively faster pace means that a lot of background details that aren't directly relevant to the plot are left open-ended, including the specifics of past relationships, the exact details of villains' rises to power, and even the fates of some of the main characters of The Last Airbender. Considering the creators are well aware of how their show's fandom operates, this is almost undoubtedly intentional. In fact, in the Book Four commentary, they told people to write fanfic about Mako's relationship with Zuko's granddaughter because they couldn't fit her into the show.
  • Another example for Korra is alternative starting points for Korra and Asami's relationship. In Book One, Asami's father is an Equalist, an anti-bending revolutionary. A popular fanfic origin is one in which Asami fully serves them rather than turning on her father and siding with Korra. This generally involves Asami attempting to seduce Korra. A similar situation occurs with Korra having been captured by the Red Lotus as a child, at which point she and Asami are on opposite sides for a different reason, until they inevitably find each other.
• Since the Beetlejuice cartoon has an almost completely different premise than the movie did, one of the most common sources of fanfic fuel involves figuring out how the cartoon versions of Beetlejuice and Lydia met and became friends. (There is a vague back story given in the comic book adaptation, but it's unclear whether this is intended to be canon to the show.) The other question fic writers like to try to answer is, in the absence of a proper series finale, what became of the duo's relationship in the future?
• Ben 10:
  • There's plenty of All There in the Manual information on the series' background, including official bios for each alien form used by Ben, providing info about these aliens' species, planets and for some of them cultures, with only a few of them having been actually explored in the various entries. This leaves plenty of material for fans to create their own alien OCs or develop further the various planets. In addition, Ben is stated to have access to more than one million aliens on the Omnitrix, leaving a huge gap for fans to fill with their own fan-made aliens.
  • In Ben 10: Alien Force, the whole Plumber's Kid is based around the idea that a lot of alien-human hybrids exist on Earth due to former Plumbers mating with humans. This makes for an excellent justification for fans to create their own half-alien OC.
• Chip 'n Dale: Rescue Rangers leaves several questions unanswered and thereby Fan Fic writers with a desire to answer them.
  • Monterey Jack is the only Rangers whose parents we get to know. Chip's, Dale's and Zipper's families aren't even hinted at. But in Gadget's case, her father, Geegaw Hackwrench, is mentioned enough to fuel the viewers' curiosity. He is only ever seen in a framed picture in "To the Rescue" Part 3, and Gadget mentions that she has lost him more than one year prior to the events of this episode. What exactly happened to him remains unknown. In a show that has its fair share of mystery and thrillers, this just has to fuel the audience's curiosity.
  • Speaking of Geegaw, he and Monty have been in some Noodle Incident in Zanzibar which involved a cheese bread and greatly upset Geegaw. While Monty tells a lot of tales from his past which may or may not be true, this is the one that the Rangerphiles really want to know more about.
  • Gadget's mother remains entirely unmentioned. Neither Monty nor Gadget ever talks about her. But if CDRR fanfic writers have to solve the mystery of Geegaw's demise, it's only natural that they have to write something about her mother as well.
  • Then there is "Good Times, Bat Times", the episode in which Dale ends up with Foxglove as his girlfriend. It's often considered the chronologically last episode (there is no defined chronology throughout a show that has the pilot in Season 2). Either way, we don't find out how things go on with Dale in a relationship with a cute pink bat (unless you count the Boom! comics as Canon). Will Foxy join the Rangers? What'll Chip do, now that he doesn't have any competition for Gadget anymore?
  • How come there's a mouse in Hawaii that looks pretty much identical to Gadget?
• Danny Phantom:
  • Dark Danny's return, which the show teased at the end of the character's debut episode, but never came into fruition due to the show ended sooner than planned.
  • Both creator Butch Hartman, and head writer for the first two seasons Steve Marmel, wanted to do a plot where Danielle "Dani" Phantom would be introduced to Danny's family and adopted, but didn't have time to properly setup such a development. Naturally, fans like exploring this possibility in fan works.
  • Fans often wonder what, exactly, happened when Danny first gained his powers, as there's a month between the Freak Lab Accident accident and the start of the show; the accident itself is only loosely depicted in the Expository Theme Tune and in the episode "Memory Blank" (wherein the characters recreate it), and we don't see what happened in that first month at all.
  • The show in general raises some questions about the nature of ghosts and the Ghost Zone that are never given answers (or ones are just plain unsatisfying), leading to fans come up with their own creative answers for.
• Daria's Bizarro Episode, "Depth Takes a Holiday," is often relegated to Fanon Discontinuity, but other times fans wonder: if Lawndale actually has an interdimensional portal, couldn't that set up all sorts of sci-fi/fantasy fics, not to mention crossovers?
• DC Animated Universe:
  • Many people wondered what happened between the timelines of Justice League Unlimited and Batman Beyond. Fifty years had passed and many of the Justice Leaguers are gone. They've also wondered about the circumstances which led to Warhawk, son of Hawkgirl and Green Lantern, being conceived and born.
  • Not to mention the "Near-Apocalypse of '09".
• Dinotrux:
  • The show premise of dinosaurs mixed with vehicles offers so much potential for how particuliar species of dinosaurs (or other prehistoric creatures) will look like as Dinotrux. For example: how the show's version of Spinosaurus looks like?
  • The fates of Blayde, Splitter, Pounder and Gold Trux who had never appeared again in the show.
• DuckTales (2017):
  • This iteration of Darkwing Duck. After the two-parter “Let's Get Dangerous!,” many fans were hoping that his show would get rebooted as well. The episode ends with Darkwing taking Launchpad and Gosalyn under his wing, just like in the original series. What kinds of adventures would they go on in this day and age?
  • The same episode introduces the RamRod: an invention that acts as a portal to other dimensions. Not only that, but according to Taurus, every fictional universe is an alternate reality that can be accessed using the RamRod. This leads to all sorts of crossover potential.
  • In the episode, “Timephoon!” Louie accidentally sends everyone (except himself) to different time periods after he accidentally created a Temporal Paradox. An earlier episode, “The Outlaw Scrooge McDuck,” is a flashback of Scrooge and Goldie in the old west, and present day Gyro Gearloose is with them, with him even mentioning that he’s stuck there due to a time traveling accident. This implies that the two events are connected. After everyone gets back to the present day, Launchpad mentions that he saw how the world ends. Where did everyone else end up during that time, and what kinds of adventures did they go on?
• Gargoyles is an absolute treasure trove of this, thanks to its rather abrupt cancellation, and the creator's extremely detailed notes about the planned future of the mythos.
  • There was going to be a Dark Ages prequel spinoff focused on the early days of the Wyvern Clan in Medieval Scotland, when Goliath and Demona were still young lovers fighting under Hudson's guidance. Not to mention a planned Gargoyles: 2198 Sequel Series, with the cast's descendants fighting off an alien invasion (first hinted at in "Sentinel") in the far future. Both concepts practically beg for fanfiction.
  • The released notes for 2198 confirm (among other tidbits) that Elisa and Natsilane's descendants would eventually have gotten together, that Lexington and Xanatos would eventually have merged corporations, and that a line of robots based on Lexington would eventually have entered production. All dynamite ideas for fanfiction.
  • After fans pestered him about it in his "Ask Greg" Q&A forum, Greg Weisman confirmed that he did have plans to work characters from Shakespeare's The Tempest into the Gargoyles mythos. How would they have figured in the story? How would Weisman have portrayed them? How different would they have been from their literary counterparts? Note that the Gargoyles universe already includes sorcerers, Fae spirits, monstrous humanoids, volatile court politics, and an enchanted island fought over by various factions of sorcerers and spirits; a retelling of The Tempest practically writes itself.
  • After Demona and Macbeth were made immortal by the same magic spell, they canonically lived through over 900 years of human history—barely any of which has actually been seen in canon. What adventures did they get up to while Goliath and his pals were still sleeping in statue-form?
  • The interstellar war between the N'Kai and the Space-Spawn.
  • Alexander Xanatos's time studying magic under Puck's tutelage.
  • Alex Xanatos taking up the mantle of Fox from his mother (a possible future plot point that was hinted at in "Future Tense").
  • Queen Titania's relationship with Halcyon Renard.
  • Peter Maza's relationship with the trickster spirit Coyote (the specific nature of which was left rather vague in-show).
  • The careers of Canmore's descendants who took up the mantle of "The Hunter" after him.
  • Lexington acknowledging and coming to terms with his homosexuality.
  • The lives and adventures of the gargoyles in the Wyvern Clan who were all killed off in the pilot episode shortly after being introduced, and also those of Angela's rookery brothers and sisters back on Avalon.
  • The history and true purpose of the Illuminati.
  • The Redemption Squad's battle with the Illuminati after the cancellation of the Gargoyles: Bad Guys spinoff.
  • Brookyln's adventures traveling through time with the Phoenix Gate (which were going to be the basis of the proposed Gargoyles: Timedancer spinoff). All we really know from the comics is that his adventures involved losing an eye, traveling to China and Japan, meeting his loyal pet companion Fu-Dog and his true love Katana, and eventually having a son named Nashville (with a second unhatched child nicknamed "Eggwardo" on the way). Whatever he got up to while time-traveling, he apparently had to seriously sharpen his combat skills in order to survive; when he's seen again, he's sporting an armored breastplate and packing a gun, a katana, and a pair of daggers.
• Gravity Falls:
  • Three major examples of this: How the events in the show affected Dipper and Mabel's lives at home after summer vacation ended, the adventures that the Stan twins got up to after the show's end, and the kinds of adventures that Soos and Melody went on now that Soos owns the Mystery Shack.
  • Stan's ten years on the road after getting disowned and separated from Ford have increasingly become popular, especially for Dark Fic and Alternate Universe Fic.
  • Ford has spent 30 years trapped in other dimensions. What kinds of adventures did he go one during all of that time?
  • Wendy's mother is simply 'no longer with her family'. What does that mean? What effect does her absence have on Wendy or her family?
  • Pacifica and Gideon are both beginning to embark upon their redemption journeys.
• Hey Arnold!:
  • The series was supposed to end with The Jungle Movie, which would have seen Arnold and Helga admit their true feelings for each other, and would have seen Arnold finding his parents, but the show was cancelled and the movie was put on the back-burner. However, creator Craig Bartlett has revealed bits and pieces of the finale's intended plot, and the fanfic community has responded in kind. With Nickelodeon producing it as a TV movie over a decade later, the fans can now see how similar their takes on the story were to the final film.
  • Ditto for Bartlett's unproduced spinoff The Patakis, about the home life of a teenaged Helga. The pilot script was apparently too dark for Nickelodeon, but Bartlett has revealed enough details for the fanfic writers to use. Unlike The Jungle Movie, Nickelodeon has not given this the green light yet.
• Infinity Train:
  • The train itself. Since it already has the mysterious ability to travel through dimensions, fans like to imagine that humans from the show's Earth aren't the only passengers on the train, and that it can be host to beings (both human and non-human) from various different timelines and dimensions. Cue half of the fics for the fandom consisting of crossovers with other works.
  • The other half are mostly Continuations: what is [X]'s life like now that they're off the train? Creator Owen Dennis has stated he had no interest in deeply exploring the lives of characters after they've gotten their exit, which only gives more reason for fanfic authors to do the job themselves and imagine how each season's protagonists are doing now that they're back on Earth and have to deal with not having reflections, being made of metal, or just their lingering emotions about spending weeks/months/years of their lives on the locomotive.
• Invader Zim:
  • The show contains a surprising amount of background detail upon which numerous fans can and have elaborated, ranging from an interstellar war to Irken reproduction. Especially since the show was canceled just as it was developing a Myth Arc, and the creators have revealed their basic plans to fans.
  • The "Battle Void" Story Arc from the comic book continuation features a series of Zims from Alternate Universes, most of them very bizarrely different from Zim himself. This has proven very inspirational ground for fanfic writers, as has the Start of Darkness for the arc's main antagonist, Zib, an alternate Dib who defeated his Zim then merged with his PAK.
• Jellystone!: An unorthodox example; fans of the show are fond of redesigning characters from other media, particularly Funny Animal ones, in C.H. Greenblatt's style and calling them the Jellystone versions of them.
• Jimmy Two-Shoes:
  • Who is Beezy's mother/Lucius' wife, and what happened to her? There was a Mrs. Heinous in the early stages of the series' development, but in the final product, she's Lucius' Rich Bitch girlfriend Jez.
  • How did Jimmy and Heloise end up in Miseryville? This was actually addressed in the original pitch (which was that Jimmy and Heloise died and went to Hell — by accident in the former's case), but since the final product makes its canonicity dubious, fans have often created their own theories in place, often with elements from the original concept.
• Kim Possible has some common jumping-off points:
  • Graduation from high school was the ending for the series but presumably a new beginning for Kim and Ron. Quite a few fics follow their adventures to college and beyond to adult life.
  • A new beginning is also suggested for Dr. Drakken and Shego, who end up helping save the world instead of menacing it and apparently become a couple.
  • The planet Lorwardia was introduced with just enough information to suggest that it's the homeworld of a Proud Warrior Race.
• The Loud House episode "The Loudest Mission" gives us two — 1) Who's going to buy the Santiago residence? 2) What adventures will Ronnie and Bobby have with their relatives? The latter question was eventually answered by the spinoff series The Casagrandes.
• The Magic School Bus has a pretty devoted fanfic community, largely because of all the tantalizing questions about the characters that it leaves unanswered. Where exactly did Miss Frizzle come from, and how did she get her famous bus? What sort of relationship did she have with her sister Fiona before she replaced her as teacher? Are there any other teachers at the kids' school, and are they all as... "interesting" as Miss Frizzle? How did the kids handle adolescence and adulthood? And what were things really like at Phoebe's old school?
• Miraculous Ladybug:
  • Are Marinette and Adrien protected (by their miraculouses) against Hawk Moth's powers? If not, their akumatized selves are often represented, and nicknamed White Cat and Miss Fortune, respectively. However, the episode "Zombizou" seems to confirm that they aren't protected against akumatization. Furthermore, the akumatized Chat Noir is canonically named Chat Blanc, which is French for "White Cat".
  • Many fanfics have them revealing their secret identities to each other, which has yet to happen in canon, though they have come close a few times.
  • What is the Peacock Miraculous doing in Gabriel Agreste's safe? Fans speculate that either he or his wife used to be the holder, and their costumes are often represented.
  • In "Chameleon", Marinette's friends and classmates are quick to force her out of her seat with No Sympathy and are quick to believe that she's picking on Lila when she tries to debunk her lies, leaving Mari to nearly get akumatized twice. The episode has lead to a large number of fics that involve Marinette getting ostracized from her class and/or getting akumatized, while the class is no longer trusted by her after they realize what they've done.
  • The American special reveals that there is a Miraculous set based on Native American culture, with Jess gaining the Eagle Miraculous, and Word of God revealing the identites of the others. What do the others look like, and who gets them?
• The Owl House: The Grand Finale offers multiple of them:
  • There is a three-year Time Skip that reveals that Luz has been frequently navigating the human and demon realms. Now that the human and demon realms can easily be accessed to each other, this opens up many possibilities of humans and demons exploring each other’s realms.
  • The Collector decides to adventure into space at the end of the series. What kinds of adventures will he get up to?
  • The fact that as a Titan, King will outlive almost everyone else on the show, and will become a towering behemoth once he’s fully grown. What will King look and be like as an adult? How will his size and knowledge of the past impact the people of the Boiling Isles in the distant future?
• The Penguins of Madagascar,
  • In this show, Rico is animated with a large scar that crosses his beak. It has never been explained in canon, nor do the other characters draw any attention to it, as if they don't even notice it any more. For Rico's past specifically it is a common question of exactly what happened to give him the scar, and how to make it fit in with canon.
  • How the Penguins (especially Skipper) are gonna react when they learn that Manfredi & Johnson are still alive?
  • Both Uncle Nigel and Buck Rockgut mention the existence of a general Penguin HQ besides the one seen in the series, which means that there are other penguin squadrons out there. How they would look like, and does Uncle Nigel and Rockgut are members of one of them?
• The never-seen biological parents of the title characters on Phineas and Ferb. Phineas's mother and Ferb's father are married, they consider them their parents, and no mention is ever made of what happened to their biological father and mother, respectively. This has led to a lot of fan speculation on the subject.
• Pibby: The very premise of the potential series is that a mysterious glitch starts consuming the worlds of Cartoon Network and Hanna-Barbera and turning their inhabitants into its blank-eyed rainbow-spewing minions. This makes it easy for fans to come up with their own stories depicting Pibby traveling to places like Nickelodeon, the Disney Channel, Netflix, etc. and have her team up with surviving inhabitants of the worlds depicted in those channels.
• PJ Masks: Due to the show lacking a proper Origins Episode for the heroes and villains, the question of how the PJ Masks became superheroes and how they first met the Night Time Villains has generated multiple fanfics already.
• ReBoot ended with a satisfactory Grand Finale in the third season, although the seeds of a greater evil in play were revealed earlier, the Supervirus Daemon having infected the Guardian Collective (who are normally immune to virus infection). The original air date for the Season 3 finale was 1998, and good reruns on Cartoon Network brought about a fourth season in 2001 to pick up on the Daemon arc. In the interim, fanfic writers had a field day telling a Star Wars-esque battle to save the net. When the fourth season finally aired, the story was notably not the epic, sprawling battle expected but isolated encounters that took up a whole four episodes to tell. And the less said about The Guardian Code, the better.
• Regular Show has two: What happened on Earth during the three years the park was in space? And what happened during the twenty-five years between the park's return and the reunion?
• Road Rovers has loads of things for fans to expand on, including the relationship between Parvo and the Groomer, adding new Road Rovers or creating their own groups, and elaborating on the backstories of the Road Rovers.
• Rocket Power: In the episode "Welcome to OttoWorld", the Rocket gang burries a time capsule and wonders if anyone will remember them in the future. The episode ends with a scene in which the time capsule is opened again in the distant future, and we get to see four statues of the protagonists. What did they do to apparently get this famous?
• As of Season 5, Samurai Jack has been stuck in the future for 50 years. What adventures did he have during those five decades?
• Scooby-Doo:
  • The franchise in general, with its simple-but-charming formula, is perfect for any fanfic writer to jump in and play with. Much like Doctor Who, it's ultimately just about a group of close-knit friends and their never-ending travels in a Signature Team Transport, where practically anything can happen.
  • Scooby-Doo! Mystery Incorporated:
    • The original Mystery Incorporated team from the 1960s likely spent at least as much time solving mysteries as the classic crew, but their adventures are only hinted at in vague flashbacks. Exploring their adventures opens up a great opportunity for putting a darker spin on the classic Scooby-Doo formula.
    • The show's many cryptic references to past historical mystery-solving organizations who were compelled to hunt down evildoers under the Evil Entity's influence. There were the Hunters of Secrets (a quartet of Mayan warriors with a pet jaguar), the Fraternitas Mysterium (a quartet of Spanish monks with a pet donkey), the Alianza Misterio (a quartet of masked Mexican outlaws with a pet skunk), the Mystery Gang (an all-female quartet of cowgirls with a pet bull), the Benevolent Lodge of Mystery (a secret society of Victorian inventors with a pet orangutan), and the Mystery Fellowship (an eccentric high-society family of detectives living in a dark mansion that sank into the Earth).
• The Secret Show:
  • It's revealed in "It's a Hamster World" that Changed Daily and Lucy Woo were the Victor and Anita of their day back when they were agents. Only their final mission together is depicted, though, which begs the question: what must their other missions have been like? Moreover, what kind of rogues gallery did they have besides Hamster Man?
  • "Victor of the Future" depicts the future versions of Victor (who is now "Changed Pandimensionally" and goes by Jet Strong) and Professor Professor (who is an even bigger Jerkass than in the present), but not the future versions of Anita, Changed Daily, or anyone else. What are they like?
  • There were plans for U.Z.Z. to fight another group of aliens called the Puddleheads, but they were left on the cutting room floor. The Puddleheads were conceived as sworn enemies of the Floaty-heads. What would the Puddleheads look like, and how would they act?
  • Surely, U.Z.Z. has more locations around the world than just the U.K. one. Assuming there are indeed more branches of U.Z.Z., what are they like and are their adventures just as crazy as the ones with the U.K. branch?
  • What were Victor and Anita's lives like before they met and were recruited by U.Z.Z.?
• The Simpsons: The "Treehouse Of Horror XXXIV" segment "Ei8ht", which partly parodies Se7en, has a clear Point of Divergence from a classic episode ("Cape Feare") as its premise, which opens up a lot about what happened between the alternate "Cape Feare" and the main body of the segment. It helps that the premise eschews the show's typical Comic-Book Time to have the events of "Cape Feare" really occurring on the date the episode aired (in 1993), so that its 2023 segments deal with a Lisa who's aged in real time from there, a timeline preferred by fans who have trouble seeing iconic 90s kids Bart, Lisa and Maggie as smartphone-wielding modern-day youngsters. The segment also peaked the interest of many fans just by being an alternate take on what was otherwise a normal Simpsons episode, opening up potential story ideas that can be had by twisting other episodes of the show, with many wishing it was written as a full-length episode like "Not It", the show's spoof of It (2017), which aired the previous season.
• As with the various comic books, there is a lot of fandom around Sonic the Hedgehog (SatAM), including possible continuations of the prematurely aborted plot. At least one set of storytellers has gotten their hands on development material from the canceled third season of the series.
• Star vs. the Forces of Evil:
  • "Running with Scissors" is a major source of this. Marco spent sixteen years in a Year Inside, Hour Outside dimension in this episode, so fans naturally explore the possibilities of all the adventures he must have had during that time. It's also popular to build off of the bittersweet mood of the ending, which implied that Marco would have a hard time readjusting to life on Earth, which ended up not being the case.
  • Another major source is "Mathmagic", due to making Alternate Universes canonical in the lore and world of Star vs. and, more importantly, making it canonical that the characters are aware that there are alternate universes, both of which provided copious amounts of Alternate Universe Fic fuel, especially ones that expanded upon the AUs already presented in the episode.
• Steven Universe:
  • In the episode "Lars of the Stars", Lars and the Off-Colors have gone from forgotten dregs of society hiding from Robonoids in ancient, abandoned areas of Homeworld, to a Badass Crew who hijacked a ship, became Space Pirates and gained an arch-nemesis. What happened in between hiding and escaping from Homeworld, and HOW did they manage those things?
  • The episode "A Single Pale Rose" reveals that Pearl has the phone numbers of (at least) nine people. She was shown receiving Mystery Girl's phone number at the end of "Last One Out of Beach City", but it's unclear who the other numbers belong to. Where and how did Pearl get them?
  • Gem society and history can also raise various questions, because although the show has plenty of worldbuilding, quite a few things are left to the imagination due to show never straying from Steven's POV and whatever concerns him.
• Tangled: The Series ends with an epilogue rife with this, ranging from how Lance is going to raise Kiera and Catalina to what adventures Cassandra is going to have outside of Corona. Varian also becomes the Royal Alchemist and there was an idea for a spin-off show involving him that got scrapped. Naturally, there are plenty of fanfics attempting to recreate it.
• Four words: "The Tournament of Heroines". Fans of Teen Titans (2003) can only guess how this event at the end of "Winner Take All" turned out, but writers just love giving their own $0.02 on it. (And all of them notice that Terra was in the background; how that's handled depends on the writer's personal views of the character.)
• The Thomas & Friends fandom has grown increasingly famous for taking the more obscure parts of the franchise's lore and generic characters and expanding upon them, and the franchise has plenty of loose ends and [1]s for fans to work with.
• Total Drama:
  • The Show Within a Show format has naturally led to a plethora of fan seasons, often populated entirely by OCs. Not to mention the possibilities for what happens to the canon characters after the show (or before or between seasons).
  • Mike has a disorder that basically guarantees he had a traumatic past before joining the show, but this is never elaborated on. The introduction of his evil alter, Mal, only adds more fanfic fuel to the fire.
• Transformers:
  • Many have wondered what happened during the time skip between the last episode of the second season of The Transformers and Transformers: The Movie.
  • Since Transformers: Animated left quite a few questions unanswered, plenty of potential there. Especially with the AllSpark Almanac Volume 2, which contains unused Season 4 material.
    • The same goes for the Transformers: Prime finale movie, Predacons Rising — namely: Where did Megatron go; did Starscream survive his encounter with the Predacons; how will Team Prime cope after Prime's death; and what became of Shockwave? While Transformers: Robots in Disguise (2015) answered the Starscream question, it left the others tantalizingly open.
• Work It Out Wombats!: The fact that the wombat kids don't seem to have any parents opens up a wealth of fanfiction opportunities explaining their absence.
• Young Justice (2010) gets quite a lot of this with its large Time Skip and original cancellation-induced cliffhanger ending. What did the Justice League do when they were Brainwashed and Crazy? What happened to Kid Flash? How does Darkseid figure into all of this? That said, the show was Un-Canceled, so it could explore these itself.
