[[caption-width-right:280:Yeah, that's pretty much what the whole plot boils down to.]]

->"You want to surpass an oni? You're interested in a fight? Fine with me. ''Let's you and me fight.''"\\
'''--Suika Ibuki'''

''Fantasy of Utter Ridiculousness'' is a WesternAnimation/MegasXLR / [[VideoGame/{{Touhou}} Touhou Project]] crossover FanFic written during May 2012 by Curtis Wildcat. The story can be found [[http://www.fanfiction.net/s/8116027/1/Fantasy-of-Utter-Ridiculousness here.]] It consists of 8 chapters: the main story, an alternate ending, and an Extra Stage.

While Coop is putting the moon back together during the aftermath of the Glorft's failed attempt to crash it into the Earth, Megas is attacked by a Lunarian mech. During the fight that follows, an attempt is made by the Watatsuki sisters to warp them directly into the Lunar Capital, all the better to sate the Earthlings' curiosity about the previously-unknown inhabitants. Instead Megas, with Coop and his friends inside, are sent to Gensokyo when the teleportation technology malfunctions.

For a land that just got done facing off against the worst weather in its history, the perpetrator of that disaster surely can't be what they need...

The Extra Stage has Coop and the others back in Gensokyo on an alleged gift-giving tour, with his presence causing the plans of some of Gensokyo's finest to go off the deep end.

----

!! Tropes seen in both parts of ''Fantasy of Utter Ridiculousness'' include:

* ChekhovsGun: Marisa's size-changing powder. At first it only turned fairies into suitable punching bags for Megas. [[spoiler: Later, it's used to give Yuuka the means to fight Megas on even terms.]]
* CoolVersusAwesome: Megas. Versus. Suika. The author has even gone on record as saying this matchup is the main reason why he wrote the story in the first place. The Extra Stage ups the ante by pitting Megas against a scaled-up Yuuka Kazami.
* CreditsGag: The explanations in the Author's Notes are separated by one-paragraph depictions of events taking place during later visits to Gensokyo, mimicking the style used throughout Megas XLR's run. The gag returns in the Extra Stage's epilogue.
* DefeatMeansRespect: [[spoiler: While Suika never becomes friends with Coop after her defeat, she becomes more willing to give him the benefit of a doubt once her gourd is recovered. She later views the Megas-Yuuka duel as great entertainment and outright salutes her former opponent.]]
* DidntSeeThatComing:
** Yukari admits as much after witnessing the lunar explosion, and is later sidelined when Megas makes its sudden arrival in Gensokyo.
** From the Extra Stage: [[IllGirl Patchouli]] throwing Reimu catches ''everyone'' off guard.
* LeaningOnTheFourthWall:
** The characters notice that there is music in the background of each battle.
** At the end of the main story, Jamie points out something else out of place: everyone in Gensokyo, situated in Japan, was speaking perfect English.
** Marisa claims that she and Reimu both become younger while incidents are in progress, attempting to explain why the both of them look like adolescents despite being at least in their 20s. Reisen is quick to point out that this doesn't make sense.
* OhCrap:
** Suika's response [[spoiler: when she fails to react in time to the battle's final attack.]]
** Patchouli reacts with this later when she realizes that yes, that silhouette on the horizon ''is'' Megas's.
** Reimu, Marisa, Alice (and her dolls), Patchouli and Reisen share a collective one just before being on the receiving end of a Spell Card-ized Super Destructor Mode.
* SeinfeldianConversation:
** A conversation between Coop and Jamie in Chapter Four, revolving around bacon being the highest form of life on Earth, would've ended up as this if the giant fairies hadn't picked that moment to attack. Alice makes no attempt to understand what they're talking about.
** An encounter between Alice, Marisa, Patchouli and Reisen in the Extra Stage degenerates into a drawn-out argument, the topics of which range from Marisa's thieving tendencies to Reisen's memetic "useless little bunny" status.
* ShipTease: [[CrackPairing Jamie and Patchouli. Also, Koakuma and the junk man Goat]].
* TemptingFate:
** Coop, regarding Suika's desire to wreck Megas if the Ibuki Gourd isn't returned:
-->"If it means taking her down a few pegs to get her to stop, then she's more than welcome to try!"
** After subjecting Yuuka to Megas's Nitrous and burying her in a plateau, Coop confidently states that she's down for the count. All he succeeded in doing was getting Yuuka to bust out her old attack patterns.
** In Sagume Kishin's cameo, she's getting ready to reopen a museum in the Lunar Capital that was closed temporarily... then promptly ruins it by saying that it was going to be a good day for her. [[RealityWarper True to her ability,]] a "stray" shot from Megas wipes the museum off the map.

!! The main story and Alternate Ending contains examples of the following tropes:

* AnswerCut: Coop wonders at one point just who in their right mind would enjoy ''tofu''. Cue cut to Ran Yakumo, wondering why she feels she ought to defend her snack choices.
* ArbitrarySkepticism: Averted with Jamie, who points out that they ride around in a stolen robot from the future to fight space squids (also from the future) on a fairly regular basis, also bringing up some of their more outlandish adventures as well, as reasons why they shouldn't dismiss the existence of magic.
* ArsonMurderAndJaywalking:
-->'''Jamie:''' So, who else are we going to meet today? Living phantoms? Talking cats? Tofu enthusiasts?
* ArtisticLicenseEngineering: Lampshaded with Megas's Plot Sensitive Button when it reads "Technology does not work this way", just before Coop fires a reverse MIRV at Suika.
* AttackOfThe50FootWhatever: The giant fairies.
** It's a crossover with WesternAnimation/MegasXLR. Does anything more ''really'' need to be said?
* BigDamnHeroes: Marisa is able to accomplish this, although she isn't aware of it.
** In Chapter 4, Alice is preparing for the unsavory task of dodging attacks from three giant fairies, whose danmaku have become massive to match. Cue the sun, literally, as the investigative Patchouli drops her Royal Flare spell card on their heads.
* BigNo: [[spoiler: Patchouli's reaction when she discovers that most of the Mansion's library was destroyed in the Alternate Ending.]]
* CultureBlind: Alice realizes this about Coop when he, as a visitor, gave her something to drink instead of the other way around.
* CurbstompBattle: Megas deals two of these, one against Kyla's Guardsman and the other against the giant fairies.
* DeconstructionFic: One common plot in Touhou fanfiction involves one or more characters being dropped into Gensokyo and adjusting to life there, usually because of Yukari (or in this story, because of the Lunarians). The problem here arises when its Coop and the others, with [[HumongousMecha Megas]] in tow, that are warped on in; by the time the battles run their course, Reimu and Yukari are both in agreement that they do ''not'' belong.
* DestructiveSavior: The Lunarians thank Coop (albeit not in person) for getting rid of the Glorft base in the Moon, but they deemed him so dangerous that they decided to put him down. Then again, this pretty much ''is'' Coop's MO...
* DeusExitMachina: Hello, Megas. Good-bye, Yukari. See you when you wake up.
* DisasterDominoes: One of these starts with Megas’s teleportation into Gensokyo, and ends with Marisa being injured and stuck under her collection of trash. She doesn’t hold it against Coop, thankfully.
* DopeSlap: In the Author's Notes at the end of Chapter Six, Koakuma does this to Jamie so that he stops hitting on Patchouli.
** MomentKiller
* EntertaininglyWrong: Alice misunderstands "Megas" to mean that the mech is a ''magus''. Sakuya, who was eavesdropping on the group when they met, becomes unnerved when she comes to the same conclusion.
* ExcusePlot: The Lunarians, Alice's danmaku demonstration, and the giant fairy attack all serve one purpose: letting Megas fight Suika.
* FearOfThunder: Flandre, of all people. The weather patterns caused by the lunar explosion were long-lasting and intense enough that she was ''scared sane.''
* [[spoiler: FishOutOfWater: Patchouli's fate in the Alternate Ending. May also be a case of ''temporal'' water as well, given the difference in the settings.]]
* {{Foreshadowing}}: Throughout the story, a trapped Marisa can be seen struggling to grab her mini-hakkero that's just ''this... much...'' out of reach. No guesses for what happens when she finally reaches it.
* GenreSavvy: When Coop announces that if they leave now, they'll be able to catch a program he's wanted to watch, Jamie points out that it's more likely that they'll run into something they could have avoided if they left earlier. Sure enough, cue the Lunar Defense Corps...
* {{Golem}}: In addition to the "magus" deal described above, Megas is mistaken for a giant statue or puppet by Alice and the residents of the SDM.
* HalfHumanHybrid: At one point, Jamie announces to Patchouli and Kiva that one of his ancestors was a Youkai... before immediately turning this around by saying that he was just messing with them.
* IKnowMortalKombat: Since it comes off as one big game, Coop is able to get the hang of Spell Card-based combat rather quickly.
* KillItWithIce: Megas's frost sword. Fittingly, it's powered by a Strawberry Mega Slush.
* [[LetsYouAndHimFight Let's You and Me Fight]]: Suika says this when she thinks Coop is deliberately withholding her prized gourd from her. [[spoiler: One of the giant fairies Megas was fighting was responsible, albeit accidentally.]]
* {{Magitek}}:
** [[spoiler: In the Alternate Ending, Coop combines Patchouli's "Philosopher's Stone" card with Megas's systems. The resulting multi-element attack finishes off Suika and demolishes most of the Scarlet Devil Mansion's library in one go.]]
** ''[[spoiler: Divine Northern Fist: Fantastic Piledriver.]]''
* NiceJobBreakingItHero: Destruction visited upon the Forest of Magic? Marisa trapped in her own house? The giant fairies, and the subsequent showdown with Suika? Yukari, who could've prevented it all at the outset, getting decked on accident when Megas first arrives? Just another day in the life of Coop.
** The Lunarians admit that they had no idea what the Glorft were planning and were mostly hiding from them, but that if MEGAS (and her crew) hadn't been there, they probably would have stayed hidden until the Glorft would have gone away... meaning that both the Lunarians and the Earth would have been destroyed. They give this realization to themselves and resolve to be more decisive next time.
* ShoutOut: [[ShoutOut/FantasyOfUtterRidiculousness Has its own page.]]
* TrashOfTheTitans: The contents of Marisa’s house, of course, though on this occasion it almost proves to be her undoing: when Megas first appears, a Disaster Dominoes effect ends with her half-buried in her collectibles, leaving her a non-factor for most of the main story.
* UltimateShowdownOfUltimateDestiny: See ''Cool Versus Awesome'' above.
* VictimizedBystander: Pop TV memorabilia and the Three Mischevious Fairies don't mix.
* WaterWakeup: The inquisitive fairy maid tasked with waiting on Yukari at the SDM doesn't seem to realize that a pitcher of water is ''not'' how you're supposed to wake sleeping people up. A minute after doing this, the frightened fairy is forced to flee from the "scary eyeball gap lady's" wrath.

!! Tropes specific to the Extra Stage include:

* AllJustADream: The events of the alternate ending turn out to be a dream of Patchouli's.
* AttentionDeficitOohShiny: Alice likes the scarf she was given, enough that she gets distracted by its quality several times during Coop's second visit.
* ATragedyOfImpulsiveness: Yuuka's reason for attacking Megas? "You killed my flowers. Prepare to die." [[spoiler: By the time she realizes that Coop's involvement was accidental at best, the Garden of the Sun is all but obliterated.]]
* BatterUp: Yuuka briefly uses her parasol as a baseball bat to try and hit energy bolts back at Megas, complete with a ball-strike count.
* CallBack: Multiple ones to both series. Examples include:
** The return of Megas's "La Cucaracha" horn and Super Destructor Mode.
** Marisa and Reimu's respective hair colors during their PC-98 days. Yuuka herself is still sporting the hairstyle and clothes from her initial appearances.
* CallForward: The loud rock music blaring from Megas during its fights is hinted to have been Mystia's inspiration for forming Choujuu Gigaku years later.
* CastFullOfCrazy: Everything that Reisen experiences over the course of the Extra Stage leads her to conclude that everyone in Gensokyo is a complete lunatic.
* CatapultNightmare: Immediately following a dream depicting an unorthodox library raid, Patchouli jerks awake and screams Marisa's name.
* CrazyEnoughToWork: Reimu's plan for ending the Yuuka fight without any casualties; she knew there was a chance that it would end up killing her (and erasing Gensokyo by extension), but she does it anyway with no justification other than "this entire evening has been stupid enough to begin with".
* DefeatMeansFriendship: Lampshaded by both Yuuka and Reimu following the end of the former’s fight. Defied, as Yuuka’s adverse to the idea and ultimately never goes along with it even after things are cleared up between her and Coop.
* DreamingOfThingsToCome:
** The medicine that Patchouli takes to deal with her illnesses causes her to start seeing possible futures in her sleep.
** [[spoiler: In her youth, Maribel had a fever-induced dream depicting Megas and some of Coop's foes, ending with the Glorft invasion and Gensokyo's destruction. Realizing that Megas was the key, she began taking the steps needed to become a youkai and ensure the mech's survival---and by extension, Gensokyo's as well.]]
* EvilIsHammy: Well, not "evil" per se, but Yuuka's BerserkButton ''was'' pushed before her fight with Megas. The ham slowly builds up during the battle, culminating in a scream of ''"OBLIVION AWAITS!"'' when she fires her Double Spark. All traces of hamminess disappear after she finally has a chance to calm herself down.
* ExpressiveShirt: As with the games, the pattern on Yuyuko’s kimono changes to reference the plot--in this case, an array of fiery sparks.
* EyeColourChange: Alice’s eyes do this, shifting from a calm blue to a bright yellow if she’s struggling to keep her more severe emotions in line--which usually means that either Marisa or Coop are present.
* FastballSpecial: How does Patchouli get out of having to escort Megas? ''She throws Reimu at it.'' Granted the sheer stress of doing so [[SquishyWizard does a number on her,]] but somehow it still works out.
* FireForgedFriends: Coop and the others become these from Reimu's perspective as a result of the Yuuka fight, though it's not until after they leave Gensokyo that she finds herself admitting it.
* ImagineSpot: Patchouli gets one of Marisa driving Megas and destroying the Mansion’s library, after which she considers preventing Marisa from doing so to be a higher priority than taking her books back. It wasn’t likely to happen, but by then she didn’t care.
* ImportantHaircut: [[spoiler: While recovering from the Megas duel, Yuuka considers getting one of these to better fit in with the changing times. If ''Phantasmgoria of Flower View'' is any indication, she went through with it.]]
* MeteorMove: [[spoiler: The "Divine Northern Fist: Fantastic Piledriver", which is a fusion of Megas, Coop's love of pro wrestling, and Reimu's power-set.]]
* MrExposition: By Yukari's own admission, she's employed as this.
* NoodleImplements: What purpose would some wood planks, duct tape, an empty ice cream bucket, a half-full hairspray can, a jackalope plush doll, flour, marbles, a window fan and a trumpet serve in trying to wake up Yukari? No one knows but Yuyuko, and she's not telling.
* NotAllowedToGrowUp: Discussed. Marisa claims that she’s both a child at heart and a woman of at least 20 years. When asked why she still looked like an adolescent, her response is that both she and Reimu become younger whenever an incident is in progress.
* NotSoAboveItAll: Patchouli may dislike Coop and Jamie (and outright ''hate'' Megas), but even she's not immune to the allure of a pizza wrapped around a ham. [[spoiler: The end of the Extra Stage suggests that she's given in to that particular temptation.]]
* OddFriendship: There are signs of this developing between Reisen and Kiva.
* PassThePopcorn: While most of the second fight’s on-lookers are watching the combatants cautiously or anxiously, Yuyuko’s treating the whole thing like a night at the theater.
* RageBreakingPoint: The events of the main story and everything she's dreamed about since then have left Patchouli with a deep distrust and fear of Coop and his antics. When she wins the below game (while actively trying to ''lose''), her anger quickly builds up; when Reimu essentially tells her to suck it up and deal with it, she snaps and '''throws''' Reimu at Megas in her stead.
* RedHerring: When Megas returns to Gensokyo by way of Yuyuko's domain, the reader is led to believe that it destroyed part of Hakugyokurou's cherry blossom garden. [[spoiler: It's not until much later when Yuyuko confirms that what it ''really'' damaged was the Saigyou Ayakashi.]]
* RockPaperScissors: Used at one point to decide who would serve as an escort for Coop and his friends. Marisa manages to introduce dynamite into the lineup (beats paper and rock, loses to scissors), and all five participants actively use it to try and eke out a victory.
* RunningGag: Jamie getting rejected by almost every girl he meets in Gensokyo.
* SaveThisPersonSaveTheWorld: [[spoiler: Or "Save This Giant Robot Car", at least. Yukari believes that Gensokyo's existence is tied to Megas surviving long enough to put an end to the Glorft invasion in the future, and up until the present day she kept an eye on it just in case.]]
* SayMyName: ''"KIII-RIII-SAAA-MEEEEEE!"''
* ThatCameOutWrong: Reisen, after being warned by those with her not to get between them and get involved in their squabbling, proclaims that "I don't need to catch your eyes to be a distraction". She realizes her mistake too late, and the aforementioned Seinfeldian Conversation takes another turn.
* UnderestimatingBadassery: Happens to Yuuka repeatedly the longer her fight drags on.
---> '''Yuuka:''' (thinking) ''Surprises upon surprises, tricks upon tricks. Is there no end to this machine's tenacity?''
* UnwittingInstigatorOfDoom: [[spoiler: Rumia.]]
* WaveMotionGun:
** Megas's [[Anime/SpaceRunawayIdeon Idiot Gun.]] This being Megas, it doesn't work as advertised. See "Tempting Fate" above.
** When Yuuka is enlarged by Marisa's size-changing powder, her Double Spark becomes large enough to be seen from space.
* YouAreWhatYouHate: Evidence is scattered throughout the Extra Stage that Patchouli is more like Coop than she thinks. Among other things she has some familiarity with video games and associated terminology, such as CharacterTiers (thanks to her dreams), and she has to resist the urge to request a pizza-wrapped ham[[note]]From the episode "Department of Megas Violations"[[/note]] from the Mansion's kitchen. All this is despite the fact that she developed a hefty loathing for Coop, his lifestyle and his stupidity by the time they get brought up.
