What If / Fan Works

Go To

Stand-Alone Series

Ace Attorney

Ah! My Goddess



  • Sasha And The Frogs: Essentially what happens if Sasha ended up with the Plantars while Anne ends up in Toad Tower and how the different people and environment will affect both characters' development.

Die Anstalt

  • A Posse Ad Esse: What if Dr Wood's powers were real and tangible? What would happen if, by a fluke, they spread to every toy in the building?


  • Downfall works on this premise, messing freely with everything, while explicitly keeping everyone within their canon character constraints. Aizen is a plotter. Unohana is Team Mom... and she kills people with her bare hands.

Buffy the Vampire Slayer

Buzz Lightyear of Star Command

The Children's Hour

Daily Life with Monster Girl

  • Many Daily Life with Monster Girl fanfics take advantage of the series premise (the government revealed the existence of monsters to the world and created cultural exchange programs, with some humans being sent to live with monsters and monsters being sent to live with humans) to ask "What if my Original Character joined the program and had to live with several monsters?" Both the gender and the species of the monsters depend on the author's preferences.

Danny Phantom

DC Comics

Death Note

  • Constant Temptation can be summed up as "What if L and Light fell in love with each other, and had to deal with Beyond Birthday?".


Dragon Ball

The Elder Scrolls

The Familiar of Zero

  • At least 90% of The Familiar of Zero fanfics have the same concept — "What if Louise summoned someone (or something) OTHER than Saito to be her familiar?" It's a good excuse to write a Crossover. Of course, it doesn't necessarily have to be a crossover - many stories have her summoning a more badass version of Saito, or an Original Character.

Fire Emblem

Freedom Planet

Fruits Basket

  • Eyes of the Cat is solely dependent on the premise that Kyo, as the cat of the zodiac, may be able to see ghosts.

Fullmetal Alchemist

  • Best Kept Secret - What if Roy and Riza were secretly married throughout Fullmetal Alchemist?
  • Desert Gold - What if Trisha was Ishvalan?
  • Gold Eyes To Red - What if Ed and Al were half-brothers? More specifically, what if Al was half Ishvalan?


Harry Potter

  • The Child of Azkaban - what if Harry grew up in Azkaban?
  • Percy Take the Wheel - what if Percy Weasley was Promoted to Parent?
  • boy with a scar is a series of such stories, each a different AU. These include "what if Neville was the Chosen One?", "what if Petunia refused to take Harry in, and he was raised at Hogwarts?", "what if Petunia actually raised Harry as a son?", and "what if Petunia and Vernon died so that Lily and James had to take care of Dudley?"

Hetalia Axis Powers


  • Requiem for an Adventurer - What if Hilda actually did meet her end in the destruction of Victoria Van Gale's weather station?

The Hunchback of Notre Dame

Invader Zim

  • The Discount Smeet - what if an adult Dib rescued a smeet Zim from an intergalactic market, and came to see the alien as his own child?
  • Science Knows No Bounds - what if Professor Membrane met Almighty Tallest Miyuki?

Kim Possible

  • So the Trauma - What if Eric from Kim Possible: So The Drama was an "Erica"? Or, more specifically, what if Kim was gay?

Kung Fu Panda

JoJo's Bizarre Adventure

The Lion King

  • This trope is the driving force for the premise behind Where There's Life, There's Hope, a The Lion King fanfic. What if Simba had actually taken Kovu when Zira "offered" him, but to protect him and give him a better life? Needless to say, everything changes.
  • Letting Go Of Hate: What if Kiara had saved Zira?

The Lord of the Rings

The Loud House

  • Missing Linc - what if Lincoln Loud's sisters had to find him after he went missing?

Love Hina

Lyrical Nanoha

  • Game Theory: What if Precia wasn't quite as crazy? It's rather astonishing how spectacularly the story goes Off the Rails from canon due to that small change.

Marvel Comics

Masters of the Universe

  • No Place Like Home - what if Orko's uncle found a way to retrieve him from Eternia, and Prince Adam and Man-At-Arms were accidentally dragged along as well?

The Middle

  • The Middle fanfic The Final Final Redux: The question is asked as to "What if Axl Heck was informed he had the wrong time written down (by four Audience Surrogate characters) and got to take his last final on time?". The result is him getting to spend a lot more time with his new girlfriend Lexie Brooks while waiting for the results and overall, a sweet story of the two reflecting on how happy they are to have gotten together.


My Little Pony: Friendship Is Magic


  • Son of the Sannin - what if Naruto had been raised by Jiraiya and Tsunade, and the sannin had been around Konoha during those years he grew up?
    • In a more specific example in-story, what if the Uchiha clan had pulled off their planned coup d'etat?

Neon Genesis Evangelion

  • Advice and Trust is an alternate universe where Shinji kissed Asuka back when she kissed him. Some of the consequences caused by that change are: Shinji and Asuka getting together and befriending Rei, Rei falling for both teens, Hikari becoming an Eva pilot instead of Touji, Shinji never merging with Unit-01...
  • A Crown of Stars features a scenario where Shinji and Asuka's lives got worse after Third Impact until someone from another dimension took an interest in them.
  • The Child of Love is an Alternate Universe fic where Asuka had sex with Shinji and got pregnant, and that situation forced both teenagers to get their act together, fix their relationship and learn to be parents.
  • Children of an Elder God replaces the canonical Eldritch Abominations with the Great Old Ones of the Cthulhu Mythos. As a result the main characters look saner but they become Humanoid Abominations, and their world is more insane, darker and bleaker.
  • Evangelion 303: What if Second Impact never happened, the Children were adult soldiers who pilot experimental jet fighters instead of mechas, and SEELE was a terrorist organization?
  • HERZ: SEELE fails to take over NERV in 2015. SEELE is exposed, NERV becomes an UN anti-Evangelion proliferation organization, and the main characters spend the next decade getting over their psychological issues and thwarting SEELE's plans.
  • Higher Learning: What if after Third Impact, Shinji and Asuka's grandson went back in time and became their teacher to help them with their psychological issues and so averting the end of the world?
  • Last Child of Krypton: What if Shinji Ikari was Superman?
  • Neon Genesis Evangelion: Genocide features an alternate universe where NERV manages through political maneuvering to avert SEELE's attack for a time, which further results in the seclude for the Human Instrumentally Project being pushed dramatically back. Shinji gets time to recover somewhat from his latest traumas and tries to fix his relationship with his family while his father and SEELE make plans for their imminent confrontation, using new puppets and tools.

One Piece


  • Gym Leader Wiki - What if the Kanto and Johto League had in-universe Wikipedia pages?

Ranma ½

Red vs. Blue

Rosario + Vampire

  • Several Rosario + Vampire fanfics revolve around the question "what if someone OTHER than Tsukune entered Yokai Academy?". Like the Familiar of Zero example above, it's usually an excuse for a crossover, Rosario to Kiva being a notable example.


Sailor Moon

  • Cardinal King asks, "What if the Senshi had been corrupted during the Silver Millennium instead of the Shitennou?".

Shin Megami Tensei

The Simpsons

The Smurfs

  • Empath: The Luckiest Smurf has two "what if" scenarios, explored by Empath's great-grandson Traveler who has the power to explore the alternate timelines of those that he comes in contact with (similar to Waverider's ability from Armageddon 2001). In Smurfette's alternate timeline, she falls in love with and marries Papa Smurf, having a child through him and causing the entire Smurf Village to rebel against Papa Smurf and throw him and his new family out of the village. In Hefty's alternate timeline, Empath returns to Psychelia and in time becomes the next Psyche Master while Smurfette falls in love with and marries Hefty, resulting in Empath-as-Psyche Master abducting Hefty and torturing him out of spite for not being able to marry Smurfette.

A Song of Ice and Fire

  • In the A Song of Ice and Fire fic The Joinery, the entire premise is what if Ned Stark became king instead of Robert Baratheon and married Cersei Lannister.
    • The Alternate Universe Fic Ned Stark Lives, which is about Eddard Stark being allowed by Cersei to take the black instead of being executed by her insane son. Despite the War of the Five Kings being more or less averted by this change, the story is just as violent as the original series.

Sonic the Hedgehog


Star Trek

  • Explored in the alternate universes created in Between the Mountain and the River:
    • What if Vulcan never joined the Federation?
    • What if Nero succeeded in destroying Earth?
    • What if Nero never left Spock on Delta Vega?

Star Trek Online

  • Prompt #3 for the Star Trek Online forums' Unofficial Literary Challenge #7 asked for the writers to do this with their cast of characters. The results:
    • Marcusdkane's "Turn a Different Corner" had Marcus Kane stay on Vulcan and marry his friend T'Reya in 2363, rather than rejoining Starfleet to command the USS Akira.
    • Worffan 101's untitled entry changed a major detail of his prime universe Romulan character D'trel's backstory. Instead of D'trel's lover Adani being captured and tortured to death by the Tal'Shiar when they raided a Unificationist cell, D'trel died instead of Adani. The story then proceeds to the present to analyze the results of the less-bloody-minded Adani being the one to face Hakeev instead of D'trel.
    • StarSword's "The Road Not Taken" decided that rather than transferring to Starfleet when the Bajoran Militia disbanded its Space Navy, Kanril Eleya stayed in the Militia and became Space Police. In the present Eleya is now a captain (O-3 rather than O-6) in the Militia and the security chief of Deep Space 9. Results are mixed: while it's mentioned briefly that the Borg attack at Vega Colony resulted in the complete destruction of Starfleet's forces without Eleya having been there, Eleya herself is actually happier.

Star vs. the Forces of Evil

Super Sentai / Power Rangers

Star Wars

  • The Star Wars fanfic series Jedi Padme Trilogy is based on the idea of Padmé as a Jedi, as well as a few other things.
  • Reversed Destines - what if Luke Skywalker was Prince Luke Organa while his sister was Leia Amidala Skywalker and brought up by her aunt and uncle?
  • Legacy of the Red Sun: What if Luke Skywalker died, and Baby Kal-El landed on Tatooine? Also what if Han Solo remained an Imperial agent?

Steven Universe


  • An Unexpected Child basically answers the question "What if the Mistress had gotten pregnant with the Warden's child after the Lockdown of Love?"


Total Drama


Urusei Yatsura

Warrior Cats

  • Clémentine - What if Brambleclaw was told the truth about his kits prior to Squirrelflight taking them in?

Who Framed Roger Rabbit

  • The authors note for Gone Wrong mentions that the idea for the fic came from wondering what would have happened if Roger had shot Doom.


  • Quite popular for fanfics of Worm - unsurprising, since it is about superheroes. One of the most popular concepts is to swap main character Taylor's insect control power for something much more potent, but sometimes they play off of more For Want of a Nail type changes.
    • Bird poses the question "What if Taylor's first experiences after becoming a parahuman took place in an insane asylum for parahumans." The premise is taken further, with a host of additional AU elements mixed in.
