Mega Crossover/Fanfic Recs

These are recommendations made by Tropers for Fanfics, all of which have been signed. After a few samples, you will be able to judge whether you might be interested in the 'fic, based on who recommended it. No-name recommendations will be zapped. Nobody would back up the rec. Discussion of the recommendation is welcome on the discussion page. As such discussion is important, do remember to add the discussion page to the watchlist, if need be.

Do warn when a fanfic may head into homosexual or non-canon territory. Some people just don't like it, and as we all know, Shipping is Serious Business.

Individual Stories
The Chance Encounter series by Telcontar Rulz: (Chance Encounter Chance Encounter 2 Chance Encounter 3 Chance Encounter 4 Chance Encounter 5)
 * Recommended by The Enmity of Ages 1994
 * A very, very long and involved series of crossovers. The first is a straight up, but well written LOTR crossover with Kingdom of Heaven, though one does not need to know much about Kingdom of Heaven, merely the main character is a baron, raised a blacksmith after being born out of the wrong side of the bed and made a knight by his (deceased) father, and has been swept into Middle Earth by a shipwreck (this is something of a running gag throughout the series, with one boat ending up in the white tree, and later in a mediaeval French forest, causing Legolas to remark that whoever organises these multiverse jumping shipwrecks has very little imagination). In the second installment a further 2 fandoms are added, Pirates of the Caribbean and Troy. Yes, it is almost as mad as it sounds, but a lot of fun.
 * Jack Sparrow in Middle Earth...just think about it.
 * Admittedly the . The Last installment thus far is a work in progress, but is mostly done and the series shows no sign of being completed any time soon, so there will be more installments. If this troper has anything to do with it anyway.

A Tangled Web, Part 2, Part3, Part 4, Part 5, Part 6, Part 7, Part 8 by ordinaryguy2
 * Recommended by Jonathan SCE
 * Synoposis: From Part 8, Chapter 25:
 * In the first Tangled Web is where the Sliders group bounces off the TARDIS belonging to Doctor Who knocking them into the Star Trek universe. Q thought it would be funny to interfere so he helped the Borg to learn about the device used to move throughout the multiverse. Once the Borg obtained that technology the Q Continuum made Q take responsibility for the situation and have to fix it but not directly.
 * When the Borg came to Coruscant in A TANGLED WEB 2 they faced groups from Buffy the Vampire Slayer, The Six Million Dollar Man and The Greatest American Hero.
 * In A Tangled Web 3 took the Borg to ancient Greece of Xena and Hercules. Help was recruited by way of the The A-Team and SeaQuest DSV.
 * Battlestar Galactica meets V-THE SERIES as well as an alternate version of Stargate SG-1 in A Tangled Web 4. Aid came from Quantum Leap and Starman.
 * A Tangled Web 5 focused on a world populated with secret agents, cops, and detectives from numerous TV shows as well as Immortals from Highlander. Characters from Smallville and Babylon 5/Crusade were both brought to this parallel world to face the Borg.
 * A Tangled Web 6 took place on the Planet of the Apes populated with Gorillas, Chimpanzees, and Orangutans in Australia alongside characters from Mad Max and Beyond Thunderdome. Help is supplied by RoboCop, Max Headroom, Gargoyles and Vincent from Beauty and The Beast.
 * A Tangled Web 7 occurred in the late 1800's in California using many Western TV characters. Aid was brought in from characters from Due South and Alien Nation alongside several heroes from the late 1930's such as Tarzan, Indiana Jones, The Green Hornet and Kato.
 * A Tangled Web 8: The Doctors—his incarnations 1 thru 10—have gathered an army from throughout the multiverse to stop the spread of the Borg. Those volunteers that had no prior experience against the Borg were to face off with the army of the Master, while the fighters who had already fought the Borg were asked to use their experience to try destroy the Borg—or die trying.
 * Comments: And this was only the people that were on the starting away teams. Started around 1997-1998 and still ongoing. At the end of each chapter there is a short listing of any new people, their actor and which show they came from. This helps with the flow of the story by not having a note mid-paragraph saying what show the new person came from. There is also two sidestories to A Tangled Web, A More Tangled Web and Another Tangled Web.

The Vampoife Dood Who Lifed by Irredeemable Mary Sue
 * Recommended by Darkest-Night
 * Fandoms: Supernatural, Twilight, Death Note, Harry Potter
 * Synopsis: A Mary Sue infiltrates the world of Harry Potter and decides to combine it with Twilight. Four unwilling (and snarky) readers are soon drawn into the brave new world of magic, sparkles, and interactive narrators.

Hybrid Theory by Blade and Epsilon.
 * Recommended by wescotta, User:Looney Toons
 * Synopsis: A single trans-million-word story which deconstructs the Mega Crossover and Self Insert genres. The crossed-over universes, once grafted together, react explosively. Instead of a Possession Sue the self-inserts arrive as literal possessors, and the meld backfires. Characters respond with realistic horror to the discovery that someone remembers them being fictional.

Sleeping with the Girls (Volume 1, Volume 2) by Admiral-Tigerclaw.
 * Recommended by User:Looney Toons
 * Synopsis: Suddenly and without warning, an unnamed anime fan has his life thrown into complete chaos: whenever he goes to sleep, he now wakes up in the bed of a different fictional girl from an anime or manga. Much trying desperately to stay alive—and awake—ensues. As the story advances, he becomes mixed up in the plot of several of these worlds.
 * Comments: Another very well-written self-insert fic, but nowhere near as dark as Hybrid Theory. Despite the name, nowhere is there anything even close to Lemon. The story keeps in mind consequences of things you normally don't even think of (such as lack of sleep). Unfortunately the story is unfinished, however it updates at a decent pace. A more complete description can be found here on All The Tropes.

MiSTings of Neon Exodus Evangelion by Elmer Studios
 * Recommended by Shay Guy
 * Synopsis: A MSTing of Neon Exodus Evangelion.
 * Comments: For those of you who can't stomach DJ Croft, this'll make the above story bearable. Elmer Studios only covers the first "season," though, which I've read is the worst. Ctrl-F through the archives to find the first eight installments, the ninth was a joint effort with another group, Mystery Octagon Theater. Alternate links here, under "Eyrie Unlimited," which also has MiSTings of the first two parts of Undocumented Features.

Dance of Shiva by John Biles
 * Recommended by User:Looney Toons
 * Synopsis: When a coma patient awakens from her thirteen-year-long sleep in 2034, it sets in motion a series of events that involve the royal family of the Juraian empire, the Knight Sabers, and a secret bloodline of espers in an effort to thwart an apocalypse set in motion by an ancient, inhuman enemy—and may reveal the secret behind the mysterious disappearance of the Sailor Senshi decades before.
 * Comments: John Biles' Dance of Shiva blends Tenchi Muyo! (OVA continuity), Sailor Moon, Patlabor, Kimagure Orange Road and Bubblegum Crisis—along with cameos from and Shout Outs to at least a dozen other sources (including ones as far-ranging as Die Hard) -- to create a story that is by turns action-packed, comedic, and unabashedly mystical.

The Open Door by Academia Nut (Fanfiction.net version)
 * Recommended by Gentlemens Dame 883
 * Synopsis: A sequel to Academia Nut's previous Neon Genesis Evangelion/Warhammer 40,000 fic Thousand Shinji, with the newly-ascended Gods expanding their fiefdom into the other realities and involving quite a lot of characters from other fictional works, starting with Haruhi Suzumiya and going far from there.
 * Comments: Suffers a wee bit from God Mode Sue though. Of course, being a sequel, it takes something of a "You Should Know This Already" approach to the previous story's content, so beware spoilers if you step through The Open Door before reading Thousand Shinji.

The (sur)Real World by RPM
 * Recommended by User:Looney Toons
 * Synopsis: Looking for a cheap, fast idea to fill a hole in their schedule, executives from the Nippon Broadcasting Network steal the concept of MTV's The Real World. Unfortunately, the "seven ordinary people" who are "randomly selected" to share the house end up being Ranma Saotome, Kyosuke Kasuga, Urd, Mamoru Chiba, Atsuko Natsume, Ataru Moroboshi, and Washuu. Hilarity Ensues.
 * Comments: Wonderful character-driven comedy that gained quite a following in the late 1990s. Dead Fic, unfortunately, with the first of several planned seasons still unfinished. Even so, it inspired a number of other writers to offer their own spins on the setting, which are available on the same page as the stories themselves. Filled with numerous Crowning Moments Of Funny—among this troper's favorites is the moment when Ataru notices Sasami's reflection in the lake is gorgeous babe Tsunami, and arranges for his reflection to kiss her. Written in a mixed paragraph and Script Fic format, which some may find off-putting, but the script style actually is justified here as "transcriptions" of broadcast footage.

Medical Help by Checkerboard
 * Recommended by Luc
 * Synopsis: Dr. Crane, meet Dr. Horrible. Dr. Horrible, meet Dr. McNinja. Dr. McNinja, meet Batman. Readers, meet impending crossover insanity.
 * Comments: A rare treat: a triple crossover that's faithful to all three canons. And really funny, too.

Super Smash Bros. -- The Evangelion Wars by Shritistrang and Alex Warlorn
 * Recommended by Golden Darkness
 * Synopsis: To quote a TV commercial, something's gone wrong in the happy-go-lucky world of Nintendo, and it isn't because of the involvement of M-rated hero Solid Snake, fallen gaming mascot Sonic the Hedgehog, or the "Should have been included in Super Smash Bros. character" Mega Man. Various heroes are missing and it's up to the Evangelion pilots to fill the gaps. Shinji Ikari as Kirby. Asuka Langley as Princess Zelda. Rei Ayanami as Krystal. And it's only the beginning, everyone they know from their world are also brought in to replace someone, good and evil.
 * Comments: Probably Shritistrang's most epic fan fiction to date. Be warned that there are liberties with some of the source material, especially for games not released outside of Japan. And the author's from Europe, and considering how Europe is treated regarding game releases...

Yukari is Free by Social Disaster, Crimson Assassin, Passerby, Karesh, Who...Me?, TAFKaM, "Mark", and Tardboy
 * Recommended by: Mr Thumbsup
 * Summary: After the End, the girls of Azumanga Daioh pilot giant mechs and fight zombies, gangs, and an evil Porn Corporation. Hilarity Ensues. Better Than It Sounds.
 * Comments: Actually a sort of constantly-evolving roleplaying story done by a collaboration of authors, Yukari is Free has staggering amounts of crossovers. These include, but are most definitely not limited to: Azumanga Daioh, Yotsuba&!, Tengen Toppa Gurren Lagann, Portal, Gary's Mod, WALL-E, Code Geass, I could go on and on. It also uses character models from Full Metal Panic!, Lucky Star, Persona 4, and again, could go on and on. As some of the archives containing the stories have been deleted, you can get a cliffnotes version of Season 3: Part Twenty-Five or so here (The thread does derail massively after about fourteen posts). Contains yuri, among other things.

Ducktales: Twenty Years Later by Anonymous author of post no. 9643053 (Also hosted on Fanfiction.net here)
 * Recommended by: Harold And Maude
 * Pairings: Huey/Original Characters(three of them), Dewey/Webby, Louie/Gosalyn Mallard, but shipping is obviousely not the main goal of the work.
 * Summary: A Continuation Fic following each of the three nephews, assuming Don Rosa's Disney timeline. Scrooge has passed away in 1967 and left each of them one third of his massive fortune. Now, in 1970, The three of them have become estranged from one another, and must come back together to hold off a hostile takeover of the company, and ultimately avert World War Three.
 * Crosses over: DuckTales, Tale Spin, Darkwing Duck, The Three Caballeros. Hints of Goof Troop, and several general Disney Universe Shout Outs and Cameos.
 * Comments: Surprisingly good story written over the course of a month and a half based on an idea thought up on 4chan. It says "Ducktales" but really, with the exception of a lot of the characters, it's more in continuity with (Or at least welds the Ducktales universe to) Don Rosa and Carl Barks's runs on the Duckiverse comics. Also manages to weld the timelines for Tale Spin and Darkwing Duck on. Captures the globe-hopping feeling of adventure that Disney Comics are so good at, only with more violence and some romance. Ultimately just a big love letter to Disney in general. Complete at 23 chapters. Contains a fair amount of violence and swearing. Enough at least for an M rating on FF.net. A caution: The version on FF.net has been spellchecked, but the version on the blog has not.

Grand Tour by Drunken Grognard. Started as a Ranma ½ and Star Trek (both Star Trek Deep Space Nine and Star Trek Voyager) crossover, it quickly spiraled into more series, including Magical Girl Lyrical Nanoha with many series acting as a one-chapter one-shot or a cameo mentioning at most.
 * Recommended by Nanya
 * Synopsis: One day, Ryoga ends up on Deep Space Nine, then somehow ends up in the Delta Quadrant on Voyager. Now he's stuck traveling between dimensions with no real way to get home. Meanwhile, the Time-Space Administration Bureau recruits Ranma to help them find Ryoga, before serious damage to all dimensions is caused.
 * Comments: Unlike most, this one doesn't keep you guessing at the massive influx of characters. Several well-written fight scenes throughout the story, character development, some fanon derailment (much to this troper's extreme delight!). In addition, it's complete at 21 chapters. And it only took five months to complete. Most fanfiction authors could take a note or three from this guy. Plus, Nanoha and Lina (the queens of magical overkill) got to have a fight scene. (Which is also something that this Troper wanted to see!)
 * Now with a sequel entitled Journey.
 * The third story in the saga is completed. Called Odyssey, it focus on the emerging dimensional mayhem with the Star Trek cast and the forces under Grand Admiral Thrawn, with the TSAB still on alert after the events of Journey.
 * Now with its own page here.
 * The fourth story, Walkabout, is out. Like the second story, it is Earth centered, but Mahou Sensei Negima elements play a much larger role.

No Need for Destiny by Innortal
 * Recommended by User:Looney Toons
 * Synopsis: Happosai casts a spell that ends up sending Ranma and Nabiki back in time and across space to a world that will eventually become the capital planet of the Juraian empire.
 * Comments: Does an, but does it in a fairly amusing away. Some fights, but, for the most part, the characterizations and interactions are the best parts. In addition to Ranma and Tenchi Muyo!, this story incorporates elements and characters from Slayers, Naruto and Sailor Moon, among other sources.

The Finale of the Ultimate Meta Mega Crossover by Eliezer Yudkowsky
 * Recommended by Ronfar
 * Synopsis: Described by the author as Vernor Vinge x Greg Egan Crack Fic, this short story first manages to cram in Shout Outs to characters from just about everything in the entire TV Tropes Wiki, and then it starts to get even more meta. Reading it will make your head explode.
 * Comments: This story wanders into serious Viewers Are Geniuses territory and is completely insane, but wow, is it worth it.

One Piece: A Smash Adventure by Specter24
 * Recommended by Yolk
 * Synopsis: After the events of the Enies Lobby Arc, the Straw Hat Pirates are happily sailing on the seas on their way to Fishman Island... when the Thousand Sunny is swallowed by a large door appearing out of nowhere, and as it turns out, the Straw Hats have wound up in the Smash Universe, going through various worlds on their way back to the Grand Line. However, behind the scenes, a evil plot is being hatched...
 * Comments: Really, this could be one of the best stories This Troper has read in decades. Rather than going for a basic "Main Characters Are Sucked Into A Different World And Hilarity Ensues" story, it manages to go even deeper than that, all while keeping with the humor and action One Piece is known for. And somehow, the story doesn't just restrict itself to the series that Smash Brothers covers, crossing characters from Final Fantasy, Kingdom Hearts, Street Fighter, Mega Man and Twisted Metal. While quite wordy (being only 50 000 words away from exceeding the million-point mark), it's not something you can sit down and finish in an afternoon, and for the first few chapters, the grammar may seem a bit off, but all in all, probably the most unique Crossover this troper has read to date.

The Noble Nine: A Kill BillEsque Tale of Revenge, by Ed Bellis
 * Recommended by Spiri Tsunami
 * Synopsis: As the title suggests, there are heavy parallels with the plot of Kill Bill, and it features the characters known among followers of the GameFAQs Character Battles as the Noble Nine—here re-imagined as a group of assassins of varying levels of morality. Not surprisingly considering the heavy rewriting of characters, the lone member of the group who is a villain in his games becomes the closest thing to a "heroic" character found. Samus, as the lone female in the Nine, is naturally given the role of the Bride.
 * Comments: This story was originally published on GameFAQs' Board 8 by Stats Topic regular Bellis, who apparently signed up for a fanfiction.net account for the sole purpose of archiving it there. While the Nine and the other characters from their games form the majority of the cast, there are random incursions by characters who are not only unrelated to any of the Nine, but have also never appeared in a Character Battle. Also of note is that almost everyone undergoes a complete alignment reversal—so Lawful Good characters like Mario and Crono become Chaotic Evil (both Ax Crazy, and the latter a Blood Knight), while Chaotic Good Sonic the Hedgehog becomes Lawful Evil and Sephiroth becomes the most sympathetic of the Nine and the only one who doesn't seem like he really deserves to die. Truly a Crazy Awesome AU.
 * Also, Shipping warning: Yes, the parallels with Kill Bill do include Samus being pregnant with the child of the Nine's leader, . (As well as Let's face it, this story pretty much is "Kill Bill with video game characters".)

Mobile Battalion Gundam Wars by Lynxara
 * Recommended by: Leafy8765
 * Synopsis: Heroes and villains from throughout Gundam's Dark History are abducted by a mysterious, seemingly omnipotent being called the Beyonder. Placed on a copy of Earth, they are divided into teams and ordered to battle as part of a deadly game...
 * Comments: The story is very well written, the action keeps you on the edge of your seat and the idea is fresh.
 * Well put together, but some forgotten core details ruin the story for some readers leading to an Anyone Can Die scenario that can't be taken very seriously. Anyone Can Die befits a Gundam story, but suspension of disbelief is lost when video-game physics is put in place.
 * Relax, that part was a plot device and the fights have become a bit more in universe, plus Turn A is in the hands of Amuro Ray

Mighty Morphin Mecha Rangers by Thaeonblade (link here)
 * Recommended by: Not JM Keynes
 * Synopsis: When Angel Groove is attacked by ridiculously powerful enemies, what does Seto Kaiba do? Blackmail Simon the Digger, Roger Smith, Bit Cloud, Van of Fanelia, and Shinji Ikari to join forces and fight them! This was either an awesome or a really bad idea!
 * Comments: It started as a really funny Power Rangers-like Deconstructive Parody, with the battles getting more and more Crazy Awesome (and funny too), while the collateral damage to the titular city getting worse and worse after every enemy attack, the fic has started to show an interesting plot, with the villains of each series making a team up, but there's more plans and factions there, and, even if it's in the first chapters, there's space for reasonable Character Development, especially on Shinji. Loads and Loads of Characters and it's pretty interesting.

The League of Extraordinary Games or LXGames by Shadymissionary
 * Recommended by: Weird Kev 27
 * Synopsis: Arbiter, Link, Lara Croft, Solid Snake, Pyramid Head, Gordon Freeman, Casey Lynch and Pikachu get together to save the world. Better Than It Sounds.
 * Comments: It's pretty much The League of Extraordinary Gentlemen with video game characters. Shadymissionary does a really good job at keeping the characters in character and has interesting grasp about how a world inhabited by every Video Game ever made would look. Is an enjoyable read for Gamers and Non-gamers alike!

Operation Winged Seed, Waltzing with Destiny, and 00 Frozen Teardrops by Aldaeus
 * Recommended by: Xamusel
 * Synopsis: From Fanfiction.Net regarding the first story: "AC 195 Operation Meteor has begun, Dr. J decides Heero could use a little help with the mission so he "borrows" a certain ship, and five pilots...". Better Than It Sounds.

Real World by Anakin McFly
 * Recommended by: Ashlyn Nyx
 * Synopsis: From the site: "Several movie characters get zapped into the real world, where they have to deal with each other and the discovery that they're fictional." Involves Back to The Future, The Matrix, Bill and Ted, The Frighteners, Star Wars, and Hitch Hikers Guide to The Galaxy to an extent.
 * Comments: Fascinating, as well as funny, and a bit dark at times. I particularly like the way certain characters' reaction to learning that they're fictional was written. While I think Star Wars did little for the overall plot, I still enjoyed the story, and recommend it to anyone who likes a good Doppelganger Crossover.

Authors
The Zero City Saga by ZC Founders.
 * Recommended by Joey411.
 * Synopsis: A new, sprawling video game fanfic by two people; one doing most of the writing, the other co-authoring the plot and storylines. Imagine countless video game characters living in one Earth city. Gets a little more complicated from there, especially with story arcs developing.
 * The first few chapters are just a teensy bit rushed, and the first stops just short of a homonym extravaganza. Also, as per authors' request, skip the latter half of the "Familiarity" chapter. After the birthday party. PLEASE.
 * Beware. Much cross-canon shipping is promised on the horizon.

The works of Finmonster
 * Recommended by Bulletproof Idea
 * Fandoms: The Wonderful World of Harry Potter, Marvel comics, DC comics, Darkhorse comics.
 * Synopsis: Basically, Finmonster asks what would happen if every comic book universe existed in the same universe, and then he threw in Harry Potter for good measure. His Marvelous World of DC series includes every single comic book character ever coexisting in a single universe. The first story is the set-up, introducing the characters, and the second is a Harry Potter focused story.
 * Comments: The really priceless thing about this series is the way the characters interact. Ever wondered what would happen if Superman were being monitered by the MIB? What if Thor and Wonder Woman were good friends? What if Harry Potter were adopted by the B.P.R.D.? What if Raven was his adopted sister? Really, Part 1: In the Begining is just a fun read to see how the character from different universes interact. Harry Potter and the Guardian's Light has more of a plot, solves the first book's mystery in a single chapter, confronts the holes in Dumbledore's plan, and makes the B.P.R.D. Harry Potter's adopted family.
 * And now, he's written Nieghbours in the North, a christmas fic, Metropolis, a story about life in Metropolis with Superman, Wonder Woman, Spider-man and Thor, and Batman, the Dark Crusade Batman's origin story with his childhood friends Tony Stark and Danny Rand.

Phantom and V by Z Shadow
 * Recommended by Lizard Of Aus
 * Synopsis: Put simply, Phantom and V meet, fight, then team up to battle random shit from every pop culture source imaginable.
 * Comments: Starts from this video. Quality does get marginally better as it goes on. Not much to recommend it by, but an interesting and amusing watch for people with too much time on their hands.

Haloid & Dead Fantasy by Monty Oum
 * Recommended by Mega Troop X
 * Synopsis: In Haloid, Master Chief battles Samus Aran. Dead Fantasy features a battle royale between the ladies of the Dead or Alive and Final Fantasy series.
 * Comments: These are Fan Films. Some of the best independent rendering I've seen. Great fight choreography.

Vathara
 * Recommended by Much Good Little Time
 * Warnings: violence, mind-bending, and the very occasional homosexual pairing.
 * Vathara is (in this troper's humble opinion) the Penultimate Queen-Master of The Crossover. Her Urban Legends ficverse (the largest to date, some 50-plus installments) encompasses (at the time of this edit) the following series: Stargate: SG-1, Airwolf, Rurouni Kenshin, Gargoyles, Godzilla the Series (the animated one with the movie tie-ins), The Sentinel, Something is Out There (a long-lost tv show), The Real Ghostbusters, and Seven Days. Occasional cameo guests from JAG, The Invisible Man, Mutant X, Tremors (the movies), and even TSR's Forgotten Realms drow have briefly guested in.

The works of Carrotglace
 * Recommended by Artful
 * Carrotglace has written a number of Mega Crossover stories based on Ranma 1/2, Sailor Moon,, Harry Potter and Star Wars of all things. Although his main character is generally a self-insert, he makes it work by forcing that character to be his own Cosmic Plaything. Why this guy isn't published yet, I have no idea.

Final Fighting Fantasy by Splash Khat
 * Recommended by Clendy82
 * Synopsis: A massive crossover of every Final Fantasy game from I to VII, encapsulating Loads and Loads of Characters. The premise is that the heroes of the various games have been sent to another world and forced to thin out their own ranks due to a perceived imbalance between good and evil.
 * Comments: In the story-as-animation category. It doesn't sound like much, but the plot quickly picks up after the first couple videos. The key selling points are the clever, if somewhat over-the-top, dialogue and characterization, the fight choreography, and the trance music that accompanies them. Guaranteed to make a fan out of you if you've ever wanted to see Kain from Final Fantasy IV as a Magnificent Bastard. Newly returned after a years-long hiatus, so now's the time to check it out!
 * 'Newly returned', you say? I would very much like to see a link if there are any new episodes that have been released.

Super Mario Bros. Z by Alvin Earthworm
 * Recommended by Retnuh
 * Synopsis: This series combines the Super Mario Bros.. and Sonic the Hedgehog universes with the over-the-top action of Dragonball Z to create the best flash video series on the net.
 * Comments: Known for, as described above, its DBZ action with the main characters, but also for making many, many Continuity Nods to the numerous Mario games that have been released over the years. Was so popular and well known amongst people on the internet, the creator suffered a surprisingly huge amount of backlash from trolls and oddly enough, his own fans, pestering him about when the next episode would be released. It was so bad, that the creator, alias Alvin-Earthworm, even had his Deviant ART page spammed and he declared the series dead. Thankfully, he changed his mind and released the seventh episode sixteen months after the sixth, but general consensus from his fans say the wait was worth it.

Mortal Kombat vs. Street Fighter, Part 2, Part 3 by Proxicide
 * Recommended by Nexus
 * Synoposis: Essentially, Exactly What It Says on the Tin, but don't think about the story too much, it's just an excuse for the fighting to happen.
 * Comments: Some of the best animation and choreography I've ever seen in a flash movie. This guy seriously needs to get hired by Capcom.

Out of Range by Gerard Andrews
 * Recommended by Evondral
 * Synopsis: An epic Rescue Rangers/Secret of NIMH/The Rescuers triple crossover centering around Gadget Hackwrench. Fairly well written though it might irk some, depending on your level of fanism for the shows. (PG-13, In authors own words: Realistic Violence, Harsh Language, and Situations that may be touchy for fellow fans of the characters involved)
 * Comments: A semi-Dark Fic (No wangst or horror though, just some drama). According to the dates, It took the author 10 years to write (from 1996 to 2006) this 50-chapter fic. Fully completed and quite long, I find it highly enjoyable. Not a single spelling error in sight, good grammar, only some phrases that could have been worded better. Admittedly, the first chapter is extremely well done, but it gets a little odd after around chapter 20. Enjoyable, but you might want to enter with caution.

The Both Syllables  series by Kila (Links to the individual fics on tropes page)
 * Recommended by Ronnie
 * Synopsis: Post-Canons, a sprawling crossover of Invader Zim, Lilo and Stitch, and Buzz Lightyear of Star Command. While XR deals with gambling debts and an eccentric experiment, Zim tries to impress the Tallest by stealing tech from, and later infiltrating, the Galactic Alliance. Hilarity Ensues. Or not.
 * Comments: An interesting crossover, still in progress, that is accesible from all sides of canon- Being a fan of all 3 involved is unnecessary to enjoy it. It consists of, so far, six fanfics: two simultaneous "paths" leading up to 99 Luftballons, and one sequel to it. It is notable for its clever integration of elements, easing into the crossover, and having OCs that, despite being central to the plot, manage to stay likable and not seem out of place.

The Elijah's Cup Universe by Lembas7
 * Recommended by Caysha
 * Fandoms: Major -- Chronicles of Narnia, Harry Potter (post-Prisoner of Azkaban); Minor -- The Dark Is Rising, Bridge To Terabithia, and the Count Meren series
 * Synopsis: A complex crossover series spanning over a dozen stories so far. It chronicles the lives of the four Pevensie siblings, starting with their return from Narnia, then skipping ahead to their adulthood where they have become part of the staff at Hogwarts. It also confronts (and somewhat solves) the 'problem with Susan'.
 * Comments: Well written, by a talented author. The character portrayal is spot on, especially with Susan having to face up to Narnia again. The complexity of a multiple crossover universe is also dealt with well, as each fandom is accurate to the details, though of course Narnia is the major fandom at play.

Yu Yu Gi Digi Moon by Kanius (Rated M for violence and some adult content, but only two scenes in the "Movie" approach Lemon).
 * Recommended by TheSkrilla
 * Fandoms: Yu Yu Hakusho, Yu-Gi-Oh!, Digimon and Sailor Moon
 * Synopsis: The Tamers, Legendary Warriors, Duelists, Sailor Senshi, and Spirit Detectives join together to fight various threats to Tokyo. Individual synopses can be found on its page.
 * Comments: An epic story (in terms of length, at least), and ambitiously well done. The characterizations and inter-series interactions are superb, and the author seems to have a knack for writing battle scenes. After six and a half years, the story is still going strong, with new chapters released near-weekly. Even though this isn't a Shipping fic, there are numerous pairings, including Takato/Rika, Takuya/Izumi, Rei/Hiei, Joey/Mai, and a few Canon/OC pairings.

Digimon Fusion Kai by Kanius
 * Recommended by SoulEaterHaruhis0s
 * Fandoms: Digimon, Elements and story of Dragonball Z, guest OC appearances from other Digimon fics, implied YuYuGiDigiMoon crossover in the future
 * Synopsis: A Fusion Fic combining the characters from Digimon and premise from DBZ in an ambitious tribute to both series. Now branded with the Kai label to celebrate the fic series' near-10th anniversary. This is the latest and up-to-date version and likely the final one.
 * Comments: Very ambitious and quite in-depth. Since May 2010, the awesome-sauce story has chalked up to 57 chapters and counting! The series is in it's second season, which adapts the Artificial Human and Cell arcs. Previous Season covered the Saiyan and Freeza arcs. Much like his successful YuYuGiDigiMoon series, the author goes to great lengths to producing quality fight scenes (only the fight against Freeza's Expy is one I can safely say is too long). While it follows the basic DBZ plot, there are some twists to keep the story fresh. All but a few are in-character (Matt is Vegeta, but not a sadist; Tai is Goku, but less dimwitted). There are OCs, but they help flesh out this specific universe. Though, it's no Shipping fic, there are some pairings like Taiora, Takari, Mimato, Kenyako, and a Davis/OC pairing.
 * There are some implications this fic could be crossover'd with YuYuGiDigiMoon in the future. When? The author has not confirmed. But, wouldn't that be kinda sweet?!

The Heroes of Arcadia Series by Anthony Bault
 * Recommended by Finalhazard Jones
 * Synopsis: Imagine that your world was a small fragment of a larger multiverse. A multiverse containing the worlds of many video game heroes, anime series, and others. Imagine this, and picture the greatest of these worlds' heroes—Sonic, Mario, Link, Goku, Mega Man, and many, many others—coming together to stop the alliance of their villainous enemies. If you can picture this, you've got the multiverse of Arcadia. In other words, Super Robot Wars meets every major video game series, anime, and comic book ever.
 * The primary heroes here are joined by Anthony Bault, an accountant-ish man of Scandinavian descent living in Minneapolis, and a resident video game expert. After the events of the series are kicked off by Bowser's banishment to the world of Earth (you'll understand in the first few paragraphs), Anthony discovers he has the bloodline of the first Gamemaster, Sir Eric of the Larson Clan, and takes up the duties of uniting the worlds of Arcadia against the forces of evil.
 * Comments: This series is, quite possibly, one of the biggest Mega Crossovers you'll read. It's connected to a lot of worlds and has a huge cast (For instance, the world of Ani-Earth is the home of the Dragonball cast, the Digimon cast, the Pokemon world, even comic book series from Marvel and DC have been tied down to this world), and has spawned a lot of Extended Universe fare. Words cannot properly express how vast the Arcadian Multiverse is, and though the quality of the fics starts out as average in the first few stories, it ends up to be an absorbing and inspiring read throughout. The link to Anthony's Fanfiction.Net page contains the main Arcadian works, as well as several non-Arcadian works and even links through his favorites to the Extended Universe fare of Arcadia. If it helps (which it will), this link takes you to an FAQ on the Arcadian Multiverse, and this link takes you to the COMPLETE collection of Arcadiafic links.

The stories from StrangePointOfView
 * Reccomended by Bulletproof Idea
 * Fandoms: Disney, and Warner Bros.
 * Synopsis: The Strange Point Of View has three stories so far. The first two take place in the same universe, The Lost Tales of Fantasia and Small World University. The first is a Dark Fic, that takes the Disney fandom, gives it a dark twist and sets it in World War Two. The plan is for it to encompass every single Disney story, and to make it so all of the Fridge Horror and Alternate Character Interpretation that takes place in the story is feasible within the individual stories. Not recommended for those without Brain Bleach. The second story in the series takes place in the present with all of the modern day Disney shows, and it's early days but it seems that Alex Russo, Candace Flynn, and Kim Possible must fight some sort of Eldritch Abomination. The third fic, Harry's Eleven and the Dark Knights is not Disney, it's a Warner Bros. crossover. It's based off of Harry Potter, and so far includes the DCAU, Ocean'sEleven, Beetlejuice, Book of Eli, Sherlock Holmes, The Matrix, and Jackie Chan Adventures, among other things, with the author dropping hints that Death Note will make a future appearance.
 * Comments: Each story is very ambitious. The Lost Tales of Fantasia is an intriguing read, which will make you rethink even your favorite Disney characters. It builds a fantasticly grim world, where Hitler can dance to a Dark Reprise of a Bednobs & Broomsticks song and still be frightening. Meanwhile Harry's Eleven and the Dark Knights is a fascinating look at a Harry Potter, and facets of the wizarding world given less consideration by J.K., such as magical crime, and Mad-eye Moody. Mad-eye is featured very prominently. Both worlds are detailed and full of adventure.
 * The stories are really inventive, and a must-read if you're looking for something original. But sometimes it could feel like too much is happening at once. This could be a good thing, or a bad thing.

Shadow and Light by phouka
 * Recommended by: Looney Toons
 * Fandoms: To a solid base of post-S7 Buffy the Vampire Slayer are added elements from Doctor Who, Law and Order: SVU, Criminal Minds, Harry Potter, Discworld, Mary Poppins, The Pretender, House and even Calvin and Hobbes and Peanuts.
 * Synopsis: In the months after the end of season 7 of Buffy, the Scoobies and the miniSlayers experience revelation and tragedy and discover new allies before settling down near the Cleveland hellmouth in a house that is far more than it initially seems. As they acclimate to their new home, they discover that not all that is published as fiction is untrue, and begin to take in waifs and strays from more worlds than just their own.
 * Comments: An entertaining series of mixed shorts and multichapter stories, wherein the Scoobies and the miniSlayers find that the world outside Sunnydale, while still possessing its dark and dangerous elements, is at the same time much more pleasantly magical than they would ever have guessed.  Some of the crossover elements are little more than cameos, but others are substantial threads underlying the 'verse of these stories, whose courses intersect with the Scoobies' own on more than one occasion.  There are tear-jerkers here, and heartwarming moments, plus tension and action as well.  Definitely worth a look.

Drunkard's Walk (link) by Robert M. Schroeck et. al.
 * Recommended by User:Vorticity, User:GethN7
 * Synopsis: Colonel Douglas Sangnoir (codenamed "Looney Toons") is a metahuman operative for the United Nations ejected from his home universe by enemy action. As he travels from timeline to timeline in search of his homeworld, he encounters universes that are homes to people and situations the reader may recognize from works of fiction, but which are unfamiliar to Doug. Now with its own trope page!
 * Status: Two of the story cycles ("steps") are complete, and two more are in progress.
 * Comments: Drunkard's Walk is an Anime fanfic that has been chosen as "Best On The Web" on at least one occasion. It is by troper User:Looney Toons (along with various co-authors for several of the installments). It has spawned a discussion board and fanfics of the fanfic. Web Original.

Undocumented Features (link), a series created by Eyrie Productions, Unlimited.
 * Recommended by User:Looney Toons, User:Vorticity
 * Pairings: Many
 * Synopsis: A sprawling Space Opera blending literally hundreds of sources into a single, remarkably coherent whole with several thousand years of internal history. Despite its scope, it excels at following the lives of individuals and the effect they have on the people around them. There is no single plot that can be summarized, as the project is composed of scores of individual stories, ranging from short to novel-length.
 * Comments: The most ambitious—and often the most successful -- Mega Crossover on the web. It's not to everyone's taste, and the earlier installments, especially the four "Core" stories, are often crude (the primary author/editor refers to these as his "Crap Years"), but material written since the late 1990s has been of consistently high quality. In particular, I recommend the "Future Imperfect" sequence entitled "Symphony of the Sword" and its related storylines. Be warned that there are bi, gay, and poly characters scattered throughout these stories -- "Symphony" has a particularly large number of them, given that the cast of Revolutionary Girl Utena plays a major part in it—but since the authors prefer to leave bedroom action off-screen (with one notable exception), it's rare that anything more than PG-rated romance is seen. Be warned, though, that as of late 2008, EPU has produced over twenty megabytes of stories in Undocumented Features—and most of it is addictive.

Neon Exodus Evangelion by Eyrie Productions, Unlimited (AU)
 * Recommended by User:Looney Toons
 * Synopsis: It's Neon Genesis Evangelion mixed with a fairly large selection of games, movies and TV shows and transplanted to the authors' home town of Worcester, Massachusetts. The lead is DJ Croft, son of Lara Croft and Fox Mulder, who, in the first three chapters or so, is good at everything and liked by everyone but Gendo.
 * Comments: Be warned—the first few chapters can be rather hard to get through because of DJ Croft.
 * Kchasm: I almost didn't like this fic—the fact that kind of destroyed my suspension of disbelief.
 * User:Shay Guy wishes to note (while speaking of himself in the third person) that this is one of the most controversial Eva fics in the Anglosphere, if not the most.
 * Lanky would like to add that this is what Neon Genesis Evangelion would be if one took out the Wangst. Pointless brooding and skullfuckery are replaced by pretty genuine characters, if one can make it past the first few chapters. It's a Love It or Hate It affair, though... Be warned.

Nightmare Symbiosis
 * Recommended by Ari Rockefeller
 * Synopsis: It's a mega-crossover event between the Street Fighter and King of Fighters universes.
 * Comments: Easily one of the best crossover fics based off of fighting games. The interactions between fighters across the platforms are incredible, and the fight scenes are top-notch. Sadly, the fic hasn't been continued in a while, and I only recently re-stumbled over it thanks to a webarchive site (which is where this story is hosted).

The Xanadu Setting by several people
 * Recommended by Joysweeper (who has written a few things in it, but is far from the only writer), User:Looney Toons
 * Synopsis: At an enormous scifi/fantasy/furry costume convention set in a world that might as well be ours, all the costumes become real.
 * Comments: It's advised to start with the first one, but they're pretty self-contained. (One of the rules is that no author is to do anything that other authors have to reference, like burning down the convention center.) It tends to lean more furry than crossover, but there are exceptions, and there's a nice lack of "OMG I'm my fursona!" stories. Some very well-done stories here.
 * User:Looney Toons: Seconded. Disclaimer: For a while I was poised to enter this project by way of Ed Becerra's "Liquid Courage" plotline and its offshoots, but that was because I found the best-executed parts of this shared world to be very cool and very well done, and I wanted some. My intended participation is currently moribund, but I still check in on the project from time to time in the hopes that something new has shown up.

Arisugawa's Locket by shanejayell (warning: most of these fics are shoujo-ai).
 * Recommended by Spiri Tsunami
 * Pairings: (main cast only) Juri/Setsuna, Ayeka/Ryoko, Minagi/Sasami, Excel/Hyatt, Nabiki/Ayaka, Keiko/May.
 * Summary: Juri Arisugawa (Revolutionary Girl Utena) opens up a lesbian bar. Thanks to a variant on Washu's (Tenchi Muyo) Time and Space device, the bar exists across multiple dimensions (this was established in chapter 8), which allows characters from just about every anime imaginable (and occasionally from something other than an anime) to visit the bar.
 * Primary Fandoms: Revolutionary Girl Utena, Sailor Moon, Tenchi Muyo!, Ranma ½
 * Secondary Fandoms: Excel Saga, Vision of Escaflowne, Hand Maid May, Yokohama Kaidashi Kikou, Phantom Quest Corp., Mahoromantic, My-HiME
 * Tertiary Fandoms: Do you want this entry to go on forever?
 * Comments: The cameos are nice, but the story gets really good when it's focusing on the staff, namely the romance between Juri and Setsuna (Sailor Moon's Sailor Pluto), which results in, another plot involving Juri and other characters from Utena, or Tendo Nabiki's (Ranma 1/2) romance with Ayaka Kisaragi (Phantom Quest Corp.), which ). Many of the scenes featuring guest stars are taken from shanejayell's other fanfics, although the scenes do not read exactly the same as they did in their original context (some parts are shortened, while other parts are actually added). Really, if you're a Yuri Fanboy (or fangirl), you'll probably like shanejayell's work—of the fandoms I listed as either primary or secondary, Tenchi Muyo is the only one that I've actually seen. It's good enough to transcend the individual fandoms, IMHO.

Halloween World by spaceman, plus about half a dozen contributors, including the almighty Vathara.
 * Recommended by Weaver
 * Synopsis: Technically set in an extremely AU version of the Buffy-verse where the Halloween spell in Season Two goes out of control and instead of changing a town for a night, it changes the entire world forever.
 * Comments: Utterly Troperiffic and with a dizzying number of crossovers, mainly anime (warning: spoilers). The main story can be hard going at times but it's worth it for the various moments of awesomeness. In addition to the stories in the Community there are others on Twisting the Hellmouth, links availible in spaceman's profile.

Reforming Evil Can Be Tricky, by the MultiMediocre Knight and others
 * Recommended by Zemyla
 * Synopsis: An improvisational multi-author epic about Kim Kaphwan and other things.
 * Comments: An absolutely hilarious epic, 144 chapters long, with crossovers from large numbers of fandoms. However, the quality is sometimes inconsistent, because (a) there are multiple authors, and they sometimes have trouble communicating, and (b) each chapter was written in less than two weeks, as is the nature of the improvisation. Note that some of the characters may be OOC, but it's for a good cause.

A Winner Is You: The Collected Works by avatarjk137, plus many other contributors
 * Recommended by Endark Culi
 * Synopsis: De Centro Del Mundo, AKA the Mall of the World. In this historic location, characters from all canons participate in a grand fighting tournament, and the winner shall have a single wish granted. Who shall be victorious when all is said and done?
 * Comments: Although there is a grand plot that affects all of the stories, each of the main 22 stories in this collection were created with the goal of being better-written than any other tale and to win an unofficial award from avatarjk137. As such, the collaborating authors have put grade-A effort into many of the stories. Plenty of action, some good humour now and then, and most of the characterization is true to the source. A sequel tournament, continuing the plot of the first in a different location and with different rules, was held as well. A third tournament was begun but cancelled after two rounds due to dwindling participation and similarly dwindling motivation from avatarjk137.

Other
Heroes and Monsters of the Millenium/Supernatural Taisen by Majin Gojira
 * Recommended by SAMAS
 * Synopsis: The former is an absurdly-large conversion project for the Angel RPG that has grown into a world of its own. Characters and creatures from dozens of sources put into a blender and set to "frappe", with details mixing, colliding, and occasionally replacing each other: Mazinger Z, Gigantor, and Cutie Honey all run on Nekettsu engines that generate Pink Slime, The Anti-Monitor is the master of The Heartless, Haruhi Suzumiya is the daughter of Baron Munchausen, Akuma is a fragment of Soul Edge, The Great Old Ones include Bagan and the Vajra, The Wired encompasses The Digital World, Jack O'Neil pilots The RahXephon, and Amazo, Ultron, and the Robot Devil are all the same being.

The latter is a story similar to a Super Robot Wars game (as the title suggests) based on the above universe, in a world where monster attacks and invasions have hit the earth for more than a century, and the various organizations that have arisen to deal with them have finally started sharing notes. By order of President David Xanatos (you heard me), SG-1, UNIT, the B.P.R.D., G.U.Y.S., and even the Space-Time Administration Bureau are starting to work together.
 * I was wondering if I'd see Supernatural Taisen here. The massive crossover is extremely well handled, and makes it clear that the author knows what he's doing. If you're a fan of any of the series involved, or the super robot wars franchise (or hell, even if you're not) it's most definitely worth a read.

Roommates by Asherhyder (AU, Mostly Het-shipping (one  has slash), crossover, it's a comic)
 * Recommended bu Loracarol
 * Pairings: Canon to the stories referenced, though some interesting variations when the character does not have a canon boy/girl friend.
 * Synopsis: Asherhyder has created a universe where Jareth, Erik, Commander Norrington and Javert all live together in the same apartment. Also along for the ride (occasionally) are Crowly, Aziraphale and Legolas as they try to survive each other and life outside of their normal existance. It's Better Than It Sounds. Be warned though—spoilers abound.
 * Comments: This story is hilarious. Hilarity Ensues practically every time the author pens this work, and when hilarity does not ensue, it is well written and beautiful. The story is still incomplete at almost 170 pages, and it has a lighter and funnier "sister" called The Girls Next Door by Pika-la-Cynique. Over the course of the comic, it crosses over with Les Misérables, The Phantom of the Opera, Labyrinth, Pirates of the Caribbean,, Wicked and many others. You don't have to actually know much about the series mentioned, (though sometimes there are bonus jokes for those who do), and it may even convince you to check those things out. Sometimes this is crack, sometimes it's serious, but it is always -- always—a good read.

Code: Total Drama Reality. By Lord Maximus
 * Recommended by: Ajustice
 * Fandoms: Total Drama Island Code Lyoko
 * Synopsis: Two years after Jeremy and the others shut down the supercomputer, XANA returns and captures them all except Aelita. At the same time the Total Drama cast arrive in France after being roped into another season. Now Aelita must save her friends with help.
 * Comments: The storyline, dialogue, and action is very fresh. The writer has done a good job keeping the continuity of the story to match that of the two shows.
