* It's fortunate that Neon Genesis Evangelion and Warhammer 40,000 have already been mentioned, because Fanfic/ShinjiAndWarhammer40k combines both (obviously). What Rule Of Cool-laden method will be used to kill the Angel this time? What literally impossible thing can the AT-Field be used for next? How thoroughly can Tokyo 3 be destroyed? How much CAPSLOCK can be inserted into the next In the Name of the Moon speech? What new BatmanGambit can Shinji pull off? How much More Dakka will Kensuke need? How much carnage can apocalypse Rei inflict? Which meek, unassuming and/or pathetic character becomes completely awesome due to Shinji's mere presence?
* If it weren't for the fact that the story's over, the {{Halo}} fanfic ''FanFic/EnemyOfMyEnemy'' could be taken as this. The armies of the two sides are ridiculously huge (numbering several million), and the weapons get more and more advanced with each reveal.
* Fanfic/DungeonKeeperAmi: How bad will Ami's [[AccidentalPervert undeserved]] [[VillainBallMagnet reputation]] get? What [[{{Magitek}} clever idea]] will she come up with next? [[FromBadToWorse How bad a situation]] can she find herself in [[IronWoobie and pull herself ''out'' of]]? And just how much of an out-of-context problem can she become for the rest of the Keepers?
* Beginning a New Path, written by stargatesg1fan1, is an epic tale of Literature/HarryPotter and the Endless Crossover with a somewhat promising opening chapter... Which quickly boils down into a seemingly endless series of bad smut and over-the-top solutions to every problem (real *and* imagined) of an equal number of fictional realities. FourthWall? What are you talking about? [[spoiler: The author explicitly mentions himself as well as the cast of the movie, going so far as to have his main character ''merge'' with his ''dimensional counterpart'' and take over the production in order to make things ''right''.]] Crossovers involved include the Series/StargateSG1 and its spinoffs, several ''other'' Harry Potter realities, JusticeLeague, AVATAR, Franchise/ResidentEvil, and more - and none of these would be complete without the main character adding one or more girls from the new reality to his Harem.
* How long could Anime/YuGiOh fanfic [[http://www.fanfiction.net/s/6293387/1/Skin Skin]] possibly get? 500,000 words? 700? ''1,000,000''? The story isn't even half-way through according to the author, and while YMMV, a majority of the readers are in agreement with it only getting better as it goes on in its violent path of mind-screw dreams and over the top card-battles.
* The same as above can be said about DragonAgeTheCrownOfThorns. Counting almost 650,000 words, it has been a constant fount of epic gambits epic battle scenes, snarky humor, character developments and overall [[{{Badass}} badassery]] on the part of the seven Grey Wardens, culminating in the most recent chapters with [[spoiler:a BattleInTheCenterOfTheMind between the GuileHero / MagnificentBastard dwarven noble protagonist and the Archdemon, a confrontation that ends with the latter gaining a higher degree of sentience.]] All in all, there is no telling what will happen next because a major plot point has been changed, and it was definitely not the only one.
* Cornova and Jakayrta (writers of PokeWars) have a habit of making each battle more epic and destructive than than the last.
* The Oogakari in YetAgain might as well be the trope codifier for Fanfiction.
* [[FanFic/UninvitedGuests Uninvited Guests]]...well, let's say it starts from Yachiru burning entire 11th division brrack down while trying to bake a cake and currently at the point where the Gotei 13 using Komamura as [[spoiler: the filler villain in order to re-claim the PlotArmor that Aizen hi-jacked from Ichigo]]. Yeah, it's [[CrackFic that kind of fic.]]
* ThirtyHs. From space armor to groinsaws to killing the fuck out of planets using another planet's corpse and vampire cavemen on Mars, it might as well be called Literature/HarryPotter: SerialEscalation
* Fanfic/ImperfectMetamorphosis: How much worse can Reimu's day get? How can the situation get any worse? Exactly how much can we [[spoiler:push Reisen to the edge of despair?]]
* Every HeroicBSOD in ''[[{{Fanfic/AceCombatTheEquestrianWar}} Ace Combat: The Equestrian War]]'' gets more and more [[{{TearJerker}} tearjerking]]. Fluttershy simply blames herself for killing Razor and cries. Rainbow Dash suffers physically and mentally, thanks to [[spoiler: Gilda's]] betrayal. Then there is [[spoiler: Derpy's]] despair in chapter 15...
* The MLP fanfic [[{{Fanfic/TheImmortalGame}} The Immortal Game]] embodies this. The story starts out with the Mane 6 pitted against an evil spirit, [[spoiler: and progresses to the point where ponykind is fighting for survival against an army of monsters, and later the creator of their universe.]]
* And while we're on My Little Pony fanfics, Fallout Equestria: Project Horizons does this all the time. How many times can the author make the backstory even more tragic? How much NightmareFuel can he cram into prewar projects? How many times can Rampage messily die in a chapter? What kind of balls-to-the-walls escape plan can Blackjack come up with next, and how drunk will she be while doing it?
* ''Fanfic/TheSwarmOfWar'' starts with a few hundred humans, a few hundred Orks, and the Overmind with a few dozen Zerglings… Ends up with human armies a million strong, hundreds of Chaos Space Marines, hundreds of Daemons. hundreds of thousands of Chaos Cultists, millions of Orks, and tens of millions of Zerg (with all kinds of advanced tech brought out). And all of that is ''before'' the expansion to other planets starts…
* In ''FanFic/MegaManDefenderOfTheHumanRace'', it's noted in-story that Wily's plots keep getting bigger.
** Project G-2, AKA [[spoiler:The Mad Grinder]], is even more dangerous than Gamma.
** Episode 12 reveals the Conduit's plan of [[spoiler:robot genocide]], which is a threat to Dr. Light ''and'' Dr. Wily.
* ''FanFic/{{Draknophobia}}'' starts off with the [[VideoGame/TheElderScrollsVSkyrim Dragonborn]] Thief Petra and her [[IronicFear fear of Dragons]]. It deals with an escalated Thieves Guild storyline and towards the end fighting against Alduin. Seems like the normal storyline? Except that [[spoiler: The Dragonborn [[AscendedToAHigherPlaneOfExistence becoming a God, or a god like figure to ensure time flows normally.]]]] The seemingly final battle takes place [[spoiler: At the beginning of all time lines]]. Also, how screwed can Petra get?
* The fan DeathBattle [[http://dimension-dino.deviantart.com/art/Death-Battle-Hulk-vs-Asura-414240429 Hulk vs Asura]] consists of this most of the fight in ShoutOut to the ScrewAttack's popular fight between [[DragonBall Goku]] and Superman. Asura starts at his base Vajra form, but whenever he starts to gain the AdvantageBall, Hulk's ever [[UnstoppableRage increasing rage and strength]] cause him to eventually take it back, prompting Asura to switch to a stronger SuperMode, first his [[MultiArmedAndDangerous Six Armed Vajra]] Asura, then Mantra Asura, while his and Hulk's growing strength does more and more damage to to the land their fighting on. The fight concludes with Hulk's anger causing him to reach his [[HumanoidAbomination World]][[WalkingWasteland Breaker]] while Asura goes into his planet sized Asura the Destructor for for a final clash that [[EarthShatteringKaboom completely destroys the planet they're fighting on]] and only leaves on of them alive. [[spoiler: Its Asura.]]
