C'est La Vie is the most recent in [[http://www.fanfiction.net/s/4655125/1/Best_of_Times_Worst_of_Times a]] [[http://www.fanfiction.net/s/5147206/1/The_New_Morning series]] [[http://www.fanfiction.net/s/5448287/1/Comme_Les_Fleurs_Du_Mal of]] [[http://www.fanfiction.net/s/5498716/1/Ryo_no_TELLTALE_HEART Crossover]] [[http://www.fanfiction.net/s/5689008/1/Cest_LaVie fanfics]] between the two spin-offs of ''Anime/YuGiOh'', ''[[Anime/YuGiOhGX GX]]'' and ''[[Anime/YuGiOh5Ds 5D's]]'', whose names are all literary or musical references. A sixth fanfic is in the works, one which parallels the Anime/YuGiOhTenthAnniversaryMovie. Said fic has [[http://www.fanfiction.net/s/6802387/1/ recently been published]].

The plot is a slightly different take on the plots of 5D's Story Arcs, tailored to a theme more to the author, Genma no Ou's (and by association, he assumes, his fans') liking. It overlaps events and characters from GX in order to add an extra layer of complexity to the story; and given that it is much like any other fic about [[SeriousBusiness overly dramatic children's card games]], it attempts to entertain by adding new situations while trying to keep everyone in character.

If you were looking for the webcomic by Jennifer Babcock, about two girls living in Los Angeles, look '''[[Webcomic/CestLaVie here]]'''.

----
C'est La Vie provides examples of:
* AGodAmI: As with in 5D's, Rex Godwin; but less enthusiastic this time.
* AdaptationInducedPlotHole: The way the story begins shows that it does originally fit in the 5D's timeline up until that point. It also makes it confusing exactly ''when'' the two diverge.
* AerithAndBob: Between mixing two series with greatly opposing name themes and adding characters, these fics have this ''in spades''.
* AFormYouAreComfortableWith: X.
* AncientConspiracy: Placido has been planning his big scheme for an indeterminate amount of time.
* AndThenJohnWasAZombie: The end of Chapter 38 seems to heavily imply that [[spoiler:Paradox is Placido, the man he has been fighting since before the story started]].
* AnimeHair: Yes, in a fanfic. Kyojo has black flames for hair, Taiyou has black and red messed-up hair, Alessandro has pointed dreadlocks...
* ApocalypseHow: [[spoiler: By [[TheVirus biological warfare]],]] if Paradox is to be believed.
* AppliedPhlebotinum: Momentum's energy seems to do whatever is needed based on the plot.
* ArtificialHuman: [[ZergRush The X-Units, the Diablo]], [[spoiler:the [[BigBad Emperors of Yliaster]] save for [[{{Cyborg}} Alessandro]].]] Now includes [[spoiler:Paradox]].
* AscendToAHigherPlaneOfExistence: Placido; after he [[spoiler:dies in the past, he is brought back to life by God himself as his servant. A bionic servant.]]
* AscendedExtra: Saiga. In the anime, he's a minor character; in Best of Times, Worst of Times, he is [[spoiler:One of Darkness' henchmen. [[CompletelyMissingThePoint For about a chapter and a half]]. ]]
** The Saviour Dragons become a significant part of the plot, instead of just AssPull plot elements.
** Placido, while by no means an Extra in 5D's, is far more important in this fic, being the leader of the group.
* AuthorAppeal: The Yugioh franchise mixed with AncientConspiracy, science, {{UsefulNotes/Gnosticism}} and many other things.
* BiTheWay: Johan admits offhandedly to being bi in Comme Les Fleurs Du Mal. The fans knew it all along.
* BackForTheDead: In The New Morning, [[spoiler:Professor Cobra]] returns to complete his goal from before. Or, as it later turn out, [[spoiler:to die at the hands of an enraged Rex Godwin]].
* BadassBiker: Everyone with a D-Wheel. Including GX characters.
* BadassCreed: Summoning chants for everything important.
* BadassLongcoat: Half the damn cast. Between Jack, Hell Kaiser, cameos like Manjyoume, and OC Kyojo... there must have been a sale on longcoats.
** The evil counterpart to this is Alessandro wearing his cloak as a trench coat.
* BaldOfEvil: Jose averts this in these fics, as instead he has a long ponytail.
* BatFamilyCrossover: Basically the plot of the story.
* BatmanGambit: [[spoiler:Aki stages her own kidnapping so she and Johan can finish off Reggie and David.]]
* BigDamnHeroes: The gang does this during the [[ZergRush Diablo surge]].
* BlackBraAndPanties: Aki.
* BloodlessCarnage: When fights occur, this trope is completely averted.
* BodyHorror: Placido's transformation is played up as more disturbing than in 5D's.
* BoringImmortalHero: Somewhat avtered, as characters will die, but DeathIsCheap is is full effect so...
** Avterted with Taiyou, who is [[DeadAllAlong already dead]].
* BoringInvincibleHero: Subverted; all Main Characters have lost at some point.
* BottomlessMagazines: A twist, and one that's played with. The only time the number of cards in a player's Deck comes into question is if one player is running Deck Destruction; otherwise, it seems irrelevant how many cards a player has left, and there will always be some.
* BrainwashedAndCrazy: [[spoiler:Yusei]] and Hell Kaiser get this in the first two fics.
* BreakingSpeech: Placido has many of these.
* ButtMonkey: Arguably Judai. While not mistreated the same way as most examples, most of the unfortunate things in this stopry happen to him.
* CannotSpitItOut: Part of the conflict between Placido and Yusei's group is that Placido's information to them consists of vague comments which make him seem like a ManipulativeBastard (not to say he isn't...)
* CanonImmigrant: The Summoners.
* CanonForeigner: Four characters from the GX manga make very short cameos.
* CardGames: [[SarcasmMode subverted]]
* ChekhovsGunman: Alessandro, who appears to be a randomly-placed lackey in C'est La-Vie, later turns out to be [[spoiler:Lucciano's replacement]].
* ChurchMilitant: Considering they work for God, Yliaster come across as these.
* ClusterFBomb: The f-word is tossed around a fair bit, especially by Crow.
--> "You know what? Fuck you Judai!" Crow snapped at the red-haired man, shoving him and almost making him drop Kyojo. "Don't give me that fucking teamwork speech after you fucking went and fucking ditched the lot of us just for a fucking shot at fucking Placido! You don't know the first fucking thing about fucking group efforts!"
* CombatPragmatism: Placido. When a guard [[spoiler:sees his metal eye, he shoots the guy through the forehead with a laser beam from said eye. Then jumps down the hole like it was nothing.]]
* CrazyPrepared: Half the cards people run at any given time are about drawing cards.
** DarkerAndEdgier: At times, these fics can be this in contrast to GX and 5D's.
* [[DeathByCameo Defeat By Cameo]]: Kaiba and Fubuki show up briefly to become victims of Paradox.
* DefeatMeansFriendship: Mostly averted.
* DemotedToExtra: [[Anime/YuGiOh Yugi]]. Justified in that he's not really the main character anymore.
** Ushio gets this treatment as well, getting a single off-handed mention.
** Misty and Carly in Best of Times, Worst of Times. This is due to [[spoiler:Darkness making meals out of them]].
** Sherry Le Blanc. Justified in that [[spoiler:it wasn't actually her]].
* DepartmentOfRedundancyDepartment: See TheyJustDidntCare.
* [[DramaticThunder Dramatic Green Lightning]]
* DroppedABridgeOnHim: [[spoiler: Bommer]]
* DubNameChange: Played with; as of Redeem Us In Our Solemn Hour, the character originally called "ZONE" is apparently now called "Ylaidus".
* EaglelandOsmosis: Speaking Japanese with a Texan accent? What?
* EverythingsBetterWithRainbows: Rainbow Neos becomes a regularly-played monster, despite having only 3 appearances in GX.
* EvilVersusOblivion: Paradox versus Placido, Jose and Lucciano. The latter 3 want to overthrow the Signers to create a better world by eliminating the bad people; Paradox wants to destroy humanity altoegther.
* {{Expy}}: The characters referred to as "Summoners" are in fact borrowed from the canon of Genma no Ou's friend, Tenebrius, from a story called "Franchise/YuGiOh [[OddlyNamedSequel Tensei]]". Beacause of a mistranslation of "Tensei" as "Summoner", when it in fact means "Rebirth". Oops.
* EyeScream: Placido.
* EyepatchOfPower: Placido sports one over his right eye when he doesn't wear the conspicuous metal eyepiece. He still has the [[NumerologicalMotif Infinity Mark]] on it, however.
* FanDisservice: The end of Comme Les Fleurs Du Mal seems like it will lead into a {{Lemon}}, but it doesn't.
* {{Flanderization}}: Placido's extremist attitude gets more extreme as the story goes on.
* {{Foreshadowing}}: Seemingly one line in Chapter 38 to the [[Anime/YuGiOhTenthAnniversaryMovie Tenth Anniversary Movie]]:
-->"I will strip away the Paradox and show you truth..."
* FridgeLogic: Most of the story. The anther has strangely never been called out on it. For a good example, see RefugeInAudacity.
** An even better one occurs in Chapter 36. Jack, still recovering from a huge hit, can't feel his legs. He deduces that since his legs are fine, his spine is just shaken up. As soon as everyone goes to mobilize, he's apparently fine enough to use a pedal-operated vehicle that goes in excess of 300 km/h.
* GainaxEnding: Best of Times, Worst of Times ends with nobody really knowing what's happened.
** C'est La-Vie does this even worse.
* GeckoEnding: Slightly with The New Morning, since the effects are the same ([[spoiler:minus the questionable fates of a few characters]]). C'est La-Vie, however, is entirely out there from anime continuity, and leaves an ending that [[spoiler:leads into the Tenth Anniversary fanfic and leaves several more characters' fates in purgatory]].
* GeniusBonus: Yusei apparently understands that time is the 4th Dimension.
* {{UsefulNotes/Gnosticism}}: References get more and more frequent in later Chapters, to the point that it becomes a main theme of the story.
* GodIsEvil: "[[strike:Zone]]" "Ylaidus" is.
* GodwinsLaw: Apparently, [[spoiler:Placido was responsible for Hitler being elected]]. He was also responsible for the man's death.
* GratuitousEnglish: Judai will occasically break out into English, due to [[TranslationConvention the story being in "Japanese"]].
* GratuitousFrench: A conversation between Judai and "Sherry" in French.
* GratuitousJapanese: It's described that although the story is in English, the characters are usually speaking Japanese.
* GratuitousSpanish: Placido utters the Spanish "excelente" at one point, and Alessandro has a habit of calling Placido "El Capitan".
* GreyAndGrayMorality: Every antagonist believes that they are doing the right thing, and that the protagonists are doing what they believe is right but are fighting for the wrong side.
* HammerSpace: Hell Kaiser somehow fits the whole World of Darkness inside the Bootleg.
** This becomes somewhat of a ChekhovsSkill in C'est La-Vie, where he uses this technique to take the patients of a hospital to the World of Darkness... because it's better than being killed.
* HandWave: See TimeyWimeyBall
* HeroicSacrifice: Surprisingly, [[spoiler:Kiryu in The New Morning. While still technically evil.]]
** [[spoiler: Judai]] in Redeem Us, which pretty much [[spoiler: [[HeroicBSOD destroys]] [[TearJerker Yusei]].]]
* HeWhoFightsMonsters: [[spoiler:Paradox]]
* HoistByHisOwnPetard: Placido's [[spoiler:sabotaging Paradox's use of the Old Momentum]] results in his plan going terribly wrong when [[spoiler:it explodes and warps Judai, Yugi and Yusei straight into the clutches of Paradox]].
* HoYay: Several characters relationships come scross this way, but Judai/Yusei and Taiyou/Kyojo are the strongest.
* HumansAreBastards: The opinion of every single main antagonist.
* HypocriticalHumour: "Hey, what's with all the f** king swearing?"
* IAmNotShazam: Before an official name existed for the Three Emperors of Yliaster, they were referred to as "Infinity" as though that were the name of their organization.
* IDoNotOwn: Genma's Chapters all begin with more of less the same, [[SeriousBusiness professional-sounding]] disclaimer, to the point where it seems to be StrictlyFormula
* [[InkSuitActor Ink Font Actor]]: Three friends of the Authors from the [[http://www.janime.eu/forum.php Janime Commuity Forum]]
* InNameOnly: Syd, Lucciano [[spoiler: Sherry]]
* KilledOffForReal: [[spoiler: Judai]]
* LauncherOfAThousandShips: Not intended, but a scene in Comme Les Fleurs Du Mal resulted in a reply that "Spirit Shipping Disgusts me". [[CompletelyMissingThePoint Despite the fact that it is neither an attempt at shipping, nor even relevant to the plot.]]
* LeaningOnTheFourthWall: Placido, in Chapter 39, talks about how Yusei and Judai's dialogue may seem to their audience. In context, the audience is [[spoiler:The Gods]], but it really seems like a TakeThat to the entire franchise.
* LetsYouAndHimFight: Played straight, subverted, and anything you can imagine.
* MakesJustAsMuchSenseInContext: Kyojo's "speaking Japanese with a Texan accent" can really only be described as this.
* MartyStu: Averted. While the author has introduced characters, they haven't hijacked the plot.
* MoreThanMindControl: Placido is possessed by the God several times later in the story, acting as a conduit between him and humans.
* NearVillainVictory: [[spoiler:Placido comes within a few seconds of winning in C'est La-Vie.]]
* NiceJobBreakingItHero: Judai taking Yusei's place in Best of Times Worst of Times results in Yusei [[spoiler:temporarily losing his Signer Mark, letting the Drak Signers have at him]].
* NotQuiteDead: [[spoiler:Judai]] in The New Morning.
* OOCIsSeriousBusiness: Judai is far more serious in this fic than he ended up at the end of GX and in the Movie, though [[CaptainObvious it may have something to do with the constant antagonizing figures he has to deal with]].
* OnlyKnownByTheirNickname: "Dark Glass" has no other identity in these fics. Paradox most likely counts as well.
* OverlyLongGag: Crow's use of the F-Word can come across as this.
* PrecisionFStrike: Crow's HypocriticalHumor example is one of his many.
--> "Stop being so f**king naive!"
* PlotHole: Attempts at averting it are made by the author, who tries to explain literally everything at some point or another.
* RandomEventsPlot: Even with a back story, C'est La-Vie comes across as this at times.
* RealLifeWritesThePlot: Several Decks used in ths series include themes of real-world Tournament winners: X-Sabers, Lightsworn, etc. This is even [[LampshadeHanging lampshaded]] by Kyojo.
** later, it's revealed that the [[ApocalypseHow Apocalypse]] was caused by [[spoiler:war between the United States and North Korea]].
* RedemptionEqualsDeath: [[spoiler: Kiryu, Bommer]]
* RefugeInAudacity: Used InUniverse with Yliaster. According to [[GodIsEvil Zone]], Yliaster used groups such as the Freemasons, the [[KnightTemplar Knights Templar]] and the {{Illuminati}} as fronts for itself. Using other secret societies as a cover for another one? [[FridgeLogic Sure, why not?]]
* RetCon: Several as a result of Redeem Us in our Solemn Hour, including the changing of ZONE into Ylaidus, and the changing of TheEndOfTheWorldAsWeKnowIt from [[spoiler:biological warfare]] to [[spoiler:machine warfare hijacked by God]].
* TheReveal: Godwin is revealed to be the enemy part way through his final battle; big brother got it wrong.
** Placido's reveal is... somewhat more unique. He's revealed to be mechanical when [[spoiler: an attack [[{{Terminator}} blows half his face off, revealing the mechanical features underneath]] and startling Taiyou]].
* RoboticReveal: [[spoiler:Other than Placido, Alessandro is revealed to have many mechanical parts, and Lucciano is revealed as a Robot]].
* RougeAnglesOfSatin: "Placido" is at one point accidentally referred to as "Placid". The spelling also randomly changes from American to Canadian standard, resulting in a lot of random name changes.
-->"–When this card inflicts Battle Damage, make the ATK of 1 face-up monster 0, and it cannot change its [[{{Fanfic/LightAndDarkTheAdventuresOfDarkYagami}} ballet]] position."
* RuleOfCool: Come on, speaking Japanese with a Texan accent. That really can only come from this trope.
** Many of the moves made by characters. For example, Taiyou's [[spoiler:Five Synchro Move]].
* RunningGag: Crow swearing with the twins around, then cupping his mouth as though it will fix something. Dropped very quickly.
* SetRightWhatOnceWentWrong: Both Paradox and Placido have this goal. It's even invoked almost by name.
--> "When next we meet, you will know the truth of this world; and then, perhaps we can make right what once was wrong…"
* [[ShesAManInJapan She's a He in the Anime]]: Lucciano is changed into a woman. [[spoiler:A robot [[ThisIsWrongOnSoManyLevels woman]].]]
* ShoutOut: [[TransFormers "One shall stand..." "...One shall fall."]]
** Professor Nicholas Carswell is named for Genma no Ou's real life friend, Tenebrius, who in real life goes by the same name.
** [[SarahBrightman Fleurs Du Mal is one of Genma's favourite songs...]]
*** As are "Last Train - The New Morning" and "FREEDOM" (By La-Vie)
** Judai [[Manga/FullmetalAlchemist ripping open a gateway and yelling at the contents]].
*** Manga/FullmetalAlchemist is heavily referenced in this fanfiction - most notably, the Gate of Truth and Judai quoting Ed in Chapter 39.
** Placido intends to send Judai and Yusei to [[{{Anime/Hellsing}} Judecca]].
** In Chapter 38, Placido [[spoiler:pulls what can only be described as a [[{{Transformers}} Spark]] out of his chest, and then [[WesternAnimation/BeastWars breaks it in two to forge the Circuit]].]]
** Chapter 37 also includes a reference to the Illuminati. While this is an actual group, it simply screams AngelsAndDemons. Come to think of it, the Religious Conspiracy motif of that chapter also coincides with TheDaVinciCode.
** [[Film/SherlockHolmes "From this point on, your fate and mine will be intertwined on a journey which will twist the very fabric of nature, of reality.]]
** The name of the new fic is an extended version of the title of [[WithinTemptation Our Solemn Hour]].
* ShownTheirWork: Referneces to {{UsefulNotes/Gnosticism}}, History, and science are abundant.
* SeasonalRot: It seems this day towards the end of C'est La-Vie, but the last 2 chapters really avert this.
* SpellMyNameWithAnS: There's more than one card in the story to be referred to by multiple names.
* StableTimeLoop: Paradox and Placido seem to form one. Justified in that [[spoiler:they appear to be the same person]].
* TearJerker: Invoked with Paradox's backstory.
** Also invoked with [[spoiler: Judai's death at the hands of Paradox]].
* ThemeNaming: Alessandro is named for Italian Tenor Alessandro Safina. Too bad the Character is Spanish South American...
** Would you prefer the guy's name being [[Music/LadyGaGa Alejandro]]?
* ThereIsNoKillLikeOverkill: 8800 ATK. [[MoreDakka Triple attacking Dragon.]] [[OhCrap No defences.]] [[SarcasmMode Very subtle,]] [[spoiler:Jack]].
* TheyJustDidntCare: Some proofreading errors are especially jarring.
-->"'''Next, due to the effect of Core Releaser'''," Placido explained, holding his hand as though to receive a card. "'''Do not forget the effect of Core Releaser''';
* TimeyWimeyBall: The GX characters and 5D's characters are explained to not have aged evenly because Zero Reverse somehow messed with the flow of time in the Neo Domino area. Riiight...
* TranslationConvention: The author makes it clear that the characters are actually speaking Japanese, even if the story itself is in English.
* TronLines: Placido gets these emanating from his face whenever God takes over.
* {{Tsundere}}: A rare male example in Alessandro. He can go from polite to rude to hostile really for no reason at all.
* VillainousBreakdown: Paradox seems to have started one at the end of Chapter 38 of C'est La-Vie.
* TheVirus: Accorrding to Paradox's flashback, [[spoiler:one is responsible for the end of the world.]]
* WhatAnIdiot: Taiyou. Despite being an incredibly intelligent and skilled apprentice of the Magician Deity, he doesn't fell it necessary to hell his allies that [[spoiler:he gave Placido the three most powerful beings he ever came across for safe keeping]].
* WhatHappenedToTheMouse: Several characters randomly go missing by C'est La-Vie and never return. Not really explained why.
** As of the start of Redeem Us, Paradox's outfit is slightly different, with no idea how it got that way; and his mental conversation with Placido has long since ended, leaving no indication how it ended.
* [[WhamEpisode Wham Chapter]]: A few, but C'est La-Vie's Chapter 34 stands out. Not only does Paradox [[spoiler:defeat Kyojo,]] the guy who mentored Jack, but Placido trashes [[spoiler:Jack, Kiryu and Kyojo]].
* ZergRush: The Diablo and the X-Units. Oh god.
** Don't forget the [[NinjaPirateZombieRobot Duel]] [[ZombieApocalypse Zombies]].
