'''''Crisis on Earth-X''''' is a 2017 {{crisis crossover}} television arc, told across Creator/TheCW's Franchise/{{Arrowverse}} franchise of shows based on Creator/DCComics: ''Series/{{Arrow}}'', ''Series/{{The Flash|2014}}'', ''Series/LegendsOfTomorrow'', and ''Series/{{Supergirl}}'', while characters from ''WesternAnimation/{{Vixen}}'' and ''WesternAnimation/FreedomFightersTheRay'' also appear. It is the Arrowverse's fourth-annual crossover, following ''Flash vs. Arrow'', ''Heroes Join Forces'' and ''Invasion!''

After a [[WillTheyOrWontThey decades-long courtship]] and many {{near death experience}}s between them, Barry Allen (Creator/GrantGustin) --better known as ComicBook/TheFlash-- and [[GirlFriday Iris West]] (Candice Patton) are [[WeddingDay finally getting married]]. Naturally, the momentous occasion is attended by all of their closest friends (and enemies) -- super or otherwise.

Before their vows can be shared, the wedding is interrupted by {{evil counterpart}}s of our heroes who claim to be from Earth-X -- an {{alternate universe}} wherein UsefulNotes/NaziGermany won UsefulNotes/WorldWarII. Naturally, this rallies all of the Arrowverse's superheroes together once again for a common cause.

[[folder:characters featured in this crossover include:]]
* '''[[Characters/ArrowverseTeamArrow Team Arrow]]:''' Oliver Queen / ComicBook/GreenArrow (Creator/StephenAmell), Curtis Holt / Mister Terrific (Echo Kellum), Dinah Drake / ComicBook/BlackCanary (Juliana Harkavy), Rene Ramirez / Wild Dog (Rick Gonzalez).

!! ''Crisis on Earth-X'' contains examples of the following tropes:
* AlternateHistory: Earth-X is a reality in which Nazi Germany prevailed in WWII, leading to dark versions of our familiar heroes.
* CrisisCrossover: It's the fourth annual Arrowverse crossover.
* EarlyBirdCameo: The Arrowverse's version of The Ray makes his debut in this story arc, and will be seen again in ''WesternAnimation/FreedomFightersTheRay''.
* EvilCounterpart: As mentioned in the official synopsis and seen in the promotional artwork, dark versions of Green Arrow, The Flash, and Supergirl (at the very least) will be introduced.
* LaResistance: The Freedom Fighters of Earth-X are this to their world.
* LoadsAndLoadsOfCharacters: As per usual for the Arrowverse crossovers, [[SerialEscalation which seem to be getting bigger and bigger by the year]].
* MythologyGag:
** The crossover's promotional art (seen above), drawn by prolific DC artist Phil Jimenez, is an homage to the cover of ''ComicBook/JusticeLeague'' [[https://static.comicvine.com/uploads/scale_small/0/4/20156-2014-22492-1-justice-league-of-am.jpg #207]], which began the twentieth-annual JLA/[[ComicBook/JusticeSocietyOfAmerica JSA]] crossover arc -- itself titled "Crisis on Earth-Prime".
** The title is also evocative of ''ComicBook/CrisisOnInfiniteEarths'', which followed three years later.
* WeddingDay: The plot commences on Barry and Iris' wedding day. [[WeddingSmashers Smashing ensues]].
