Top Ten Absurdly Long Fanfictions

As we dig down when it comes to fanfiction, we come across countless amounts of fan dedicated material to read from hours to even days to no end, made by countless of amateur to seasoned writers. Some people are yet so dedicated to the fandom they love to the point that they have written such novels that span from hundreds of thousands to even millions of words long. If you are a seasoned reader, or just an ordinary reader, these are just top ten examples of absurdly long fanfiction novels that can be quite a ride.
The Top Ten
1 The Subspace Emissary's Worlds Conquest

If one thinks "what's the longest piece of literature?", then this is the first fanfiction they think of - a Super Smash Brothers fanfic spanning over 4.1 million words. The Subspace Emissary's World Conquest held its legendary title as the longest fanfiction for a fairly long time (not counting troll fics) until it was slowly beaten by Ambience: A Fleet Symphony and The Loud House Revamped. This novel revolves on a self-insert named Chris who met a clueless Lucario who was brought into the real world who goes to an adventure to prevent Subspace Emissary from taking over the world, along with some humorous dialogues in chapters as you read through. Sure this fanfiction may not be the best quality and its grammar may be shoddy at the start, but the author's motives of improving his english as he wrote this novel is otherwise a great one.

The SSMB fanfiction, being long as Wales' longest town name.

Agree completely

2 Ashes of the Past

Spanning over almost 2 million words and 300+ chapters, this is considered one of the most well known pokemon longfics there is (which is the most reviewed in the pokemon fanfiction category) and it is basically about Ash using time travel in order to counter problems while keeping his personality, while eventually getting much better in terms of character development. Overall, it's worth a read.

Ooo now that's something I should read

3 The Loud House: Revamped

Currently, this is the longest fanfiction ever written as of November 2020, and it's still going strong. Standing at a whopping 7+ million words. To sum this up, it is basically a self-insert, mashed up with a plethora of characters and countless of crossovers from different anime, cartoons, etc. as they go into an epic adventure to face the "evil". The story itself may seem convoluted and lacking in substance, but hey you gotta at least credit the dedication to the author. Plus, its got a handful of dedicated reviewers, so that's pretty sweet.

Just read a tiny part of a chapter; it's pretty wack

Honestly I don't think anyone sane can read all of that but ok

7+ million? That's a lot of words.

4 Ambience: A Fleet Symphony

Spanning over 4.5 million words and 400+ chapters, this novel may seem like it has more substance, but ironically it has received negative reception more compared to the subspace emissary's world conquest, and it is apparently another self-insert fiction. Sure this fanfiction may have numerous flaws, but it is still worth to check out. It has also once held the title of the longest fanfiction before The Loud House Revamped took its place.

5 Traveler

Since its existence in 2012, this is still standing strong with 1.3 million words, as it is updated occasionally. One of the most unique things in this story is that Ash gets a Nidoran instead of a Pikachu; an interesting choice indeed. Overall, the author has put solid effort on world building, character development, and other details that I won't explain because spoilers, except that Ash acts more serious compared to the anime. Otherwise, this fic can be a thrilling ride if you are a seasoned pokemon fanfic reader.

6 At the Edge of Lasg'len

This novel stands high in a whopping 4.9 million words long - longer than that of Ambience: A Fleet Symphony and Subspace Emissary World's Conquest. It has received quite a positive reception. As of November 2020, this currently stands as the longest fanfiction in Archive of Our Own.

7 Gladiator

An intriguing Avatar: The Last Airbender fanfiction that spans over 2.4 million words and almost 200 chapters. Published in 2013 and still going strong. It may seem to have some flaws as you read forward, but otherwise the quality and the added romance elements of this novel beats it most, even with over 2 million words - a quality that a select few authors have grasped.

8 Harry Potter and the Prince of Slytherin

If you are looking for a new experience although still harry potter related, this is considered one of the most popular fanfiction their is in the Harry Potter fandom and recommended by many. It currently stands as the Top 25 in terms of favorites, and it spans 1.1 million words long.

9 A Marauder's Plan

If you want a great ride for alternative universe stories, and at the same time you're a harry potter fan, then this fanfic which spans almost 900,000 words may be the best pick for you. The story pacing would seem slow, but the characters seem intriguing enough. Although there are some political elements, it can be worth to check out.

10 The Buzz On How Maggie Got Fondled By Flecko And Then Got Inside Her Psychiatrist's Head

Has a plot that basically is just "characters get horrifically tortured and have extremely gross and weird fetishes BECAUSE SHOCK VALUE"; basically is 80,000 words long

The Contenders
11 Sonic's Ultimate Harem
12 Child of the Storm

A fairly long novel with 800k+ words and is well known among readers, and since the Harry Potter fandom is so big when it comes to fanfiction, this is also worth a read. Especially if you are on to avengers, this can be the perfect crossover novel for you.

13 Boys In The Aviary, Baby
14 Journey To The Central Nervous Systems Of Muriel And Katz

Basically a 50,000-word-long set of Courage The Cowardly Dog episodes
