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 At the Edge of Lasg'len

At over 6 million words, this Hobbit fanfic is definitely the second-longest AO3 fanfic. The only one beating it is a 7-million-word Terminator/Firefly crossover.

This novel stands high at 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 on Archive of Our Own.

Well written, with a fantastic plot and attention to every detail. The authors answer every comment and work really hard on it.

2 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. Otherwise, the quality and the added romance elements of this novel beat most, even with over 2 million words - a quality that a select few authors have grasped.

3 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 might seem slow, but the characters seem intriguing enough. Although there are some political elements, it can be worth checking out.

4 Child of the Storm

A fairly long novel with over 800,000 words, it is well known among readers. Since the Harry Potter fandom is so large when it comes to fanfiction, this is also worth a read, especially if you are into Avengers. This can be the perfect crossover novel for you.

5 Boys In The Aviary, Baby
6 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 surpassed by Ambience: A Fleet Symphony and The Loud House Revamped.

This novel revolves around a self-insert named Chris who meets a clueless Lucario, who was brought into the real world, and goes on an adventure to prevent the Subspace Emissary from taking over the world. Along the way, there are humorous dialogues in chapters as you read through. Sure, this fanfiction may not be of the best quality, and its grammar may be shoddy at the start, but the author's motive of improving his English as he wrote this novel is commendable.

7 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 crossovers from different anime, cartoons, etc. They go on an epic adventure to face the "evil".

The story itself may seem convoluted and lacking in substance, but hey, you've got to at least credit the dedication of the author. Plus, it's got a handful of dedicated reviewers, so that's pretty sweet.

8 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 more negative reception compared to The Subspace Emissary's World Conquest. It is apparently another self-insert fiction. Sure, this fanfiction may have numerous flaws, but it is still worth checking out. It has also once held the title of the longest fanfiction before The Loud House Revamped took its place.

As one of the classic longfics, this fic was formerly known as the longest before Loud House Revamped took its throne.

9 Pokemon Crossing: Fly Me to the Moon
10 Ashes of the Past

Spanning 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). It is basically about Ash using time travel to counter problems while keeping his personality, while eventually getting much better in terms of character development. Overall, it's worth a read.

The Contenders
11 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 about this story is that Ash gets a Nidoran instead of a Pikachu - an interesting choice indeed. Overall, the author has put solid effort into world-building, character development, and other details that I won't explain because of spoilers. Ash acts more serious compared to the anime. Otherwise, this fic can be a thrilling ride if you are a seasoned Pokemon fanfic reader.

12 Future Shock - Cameron AKA Nobody

There is no other story like it. It keeps the TV show alive and running strong. Who wants their favorite show to end? I don't.

13 Harry Potter and the Prince of Slytherin

If you are looking for a new experience that is still Harry Potter-related, this is considered one of the most popular fanfictions there is in the Harry Potter fandom and recommended by many. It currently stands in the top 25 in terms of favorites and spans 1.1 million words.

14 Fallout Equestria: Project Horizons
15 The Buzz On How Maggie Got Fondled By Flecko And Then Got Inside Her Psychiatrist's Head
16 Sonic's Ultimate Harem
17 Smash Life
18 His Britannia
19 Journey To The Central Nervous Systems Of Muriel And Katz

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

20 The Mortal Instruments: City of New Life
21 Ned Stark Lives!
22 Forearmed: A Persona 5 Fanfic
23 Everything Changes
