History Fridge / CrisisOnEarthX

** Kara being Overgirl may seem odd at first, considering how she is usually so driven to help others. But, as Season 3 has repeatedly shown, Kara also has a very powerful sense of pride and of being above everyone and everything else, even with how she was raised. Earth-X would do nothing but encourage that view, meaning that instead of merely suppressing her emotions it's very easy to see how a Nazi-raised Kara could begin to see herself as an {{Ubermensch}}. In addition, Kara is basically the exact vision of the Nazi ideology's perfect being: tall, powerful, and blonde (although she does have grey-green rather than blue eyes). And while it might seem counter-intuitive that an ideology based on racial purity would accept a literal alien, historically the Nazis actually did make exceptions for non-Aryans they deemed useful or who could further their goals.

*** Except that Kara was shocked to see Oliver use a Kryptonite arrow, so no one on her Earth could've helped him. As for the Legends, it's the same issue in that they were never even told about Kryptonite, and before the crossover, everyone was under the assumption that Kara, and by extension, Kryptonians, didn't exist on Earth One.

* It is very heavily implied, given Stein correctly guessing that Earth-X’s PointOfDeparture is the Nazis gettin the Bomb, and the later appearance of [[spoiler:the Nazi-fied Waverider]], that the Legends only ''[[Recap/LegendsOfTomorrowS2E1OutOfTime barely]]'' prevented the Earth-X timeline.

** Oliver and Tommy: Assuming their pasts are otherwise similar to on Earth-1, both are the sons of wealthy oligarchs, meaning that their fathers likely hold or held a lot of power, and would be able to use that to ensure the best training and positions for their sons. Alternatively, even if that's not true, Overgirl does say that Earth-X is a meritocracy. And we already know that the Queens and Merlyns are ''very'' good at fighting.

* The diverse characters of the Arrowverse gives the ensemble of Heroes and Legends one of the strongest reasons to utterly despise Nazis any superhero team has ever had, and provide a convenient explanation as to why there was no attempt at convincing any of the Earth-1 people to change sides: of the total of 21 heroes, MissionControl team members, [[MyFriendsAndZoidberg and Mick]] from Earth-1, Earth-2, and Earth-X who appear in the crossover, only Mick, Roy, and Harry don't have an automatic personal reason to have complete contempt for Nazism. The rest are Jewish, non-"Aryan", gay/bisexual, or currently in a relationship with or have a family member who is.

** Oliver probably realized how utterly, ''hilariously'' outgunned he was faced with a Kryptonian. With Barry and other metahumans he's dealt with he and the team could come up with some method of dealing with them, but Kara was completely beyond anything Earth-1 had to offer, with no known weaknesses except alien mind-control. If he figured out there was a possibility there was a Krypton in his universe and there was no way anyone would be able to deal with them, he could very well have asked had Cisco to do some research, and Cisco might have asked Gypsy and Harry if they knew anything about Kryptonians anywhere in the multiverse, which would have led to Kryptonite.

%% Will add more examples when the rest airs.

* Considering the only experience Oliver had with Kryptonians was Kara herself, and he was never introduced to Kryptonite (in fact, Barry never was either), why does he even have any? Ostensibly it could have been synthesized, but why does he even know about it barring [[CompositeCharacter that one]] [[Franchise/{{Batman}} explanation]]?

* Oliver and Kara’s hatred of Nazis seems to come out of nowhere until one remembers that Felicity (his ex-fiancee and one of his good friends) and Alex (her adoptive sister) are Jewish and Lesbian respectively. To say nothing of Barry, who is getting married to his best friend Iris, a black woman, and was raised by Joe, her black father -- and whose wedding said Nazis promptly interrupted.
** Even past that, this is true to their characters; Oliver is also famously quite liberal in the comics, so it's true to the source material, and owes his life to many of the kinds of people the Nazis wanted to kill (i.e. black men like Diggle). Kara fits this too; she was romantically attracted to James, a black man, and was friends with an Asian-American boy named Kenny when she was in high school, who she had ShipTease with before he was murdered.
** Also...Nazis are genocidal, totalitarian maniacs who Americans fought against in WWII! They ''really don't need'' specific reasons to be against people who anybody decent would reject on principle. I know that the intent of this wasn't to say that it's uncommon for Americans to oppose nazism, but...just sayin'.v
