History Recap / JusticeLeagueS1E24To26TheSavageTime

* AllohistoricalAllusion: Towards the end, the members of the German High Command are beginning to resent Vandal Savage's actions and position. When speaking about [[UsefulNotes/AdolfHitler the previous Fuhrer]], they admit that he was crazy, but at least he listened to his generals. In real life, one of the key reasons often given for the collapse of the German military was Hitler's refusal to accept advice or corrections from his military staff (although this interpretation has come under scrutiny in recent years due to it being part of said generals [[UnreliableNarrator trying to distance themselves from war crimes in the eyes of the Western Allies]]).

The Justice League returns from a mission in space to find the world transformed – a result of villain ComicBook/VandalSavage feeding information to his younger self in the 1940s, allowing him to help take over the world during UsefulNotes/WorldWarII. The League travels back in time themselves to stop him, and fight Nazis alongside DC Comics' WWII-era heroes (including [[Comicbook/SgtRock Easy Company]], the [[ComicBook/{{Blackhawk}} Blackhawks]], and Steve Trevor).

** Two of DC's war comics that don't feature in the episode get visual references. The first episode features an M3 tank[[note]]Although it's an M3 Lee, rather than an M3 Stuart variant[[/note]] whose driver resembles Jeb Stuart of Comicbook/TheHauntedTank. And one of the wounded soldiers at the aid tent has a fully-bandaged face, making him visually resemble the Comicbook/UnknownSoldier.

* EmperorScientist: Vandal Savage, whose mastery of new wonder weapons has enabled him to usurp Hitler.

* FaceRevealingTurn: To show the Fuhrer has both a moustache AND BeardOfEvil! It's not Hitler but Vandal Savage, having usurped the former.

* GloveSnap: Savage's TortureTechnician with his gauntlets before going to work on J'onn.

** After Savage's plan to invade the United States fails, the Nazis decide to put their [[UsefulNotes/AdolfHitler rightful Fuhrer]] back in charge.

* {{Beat}}: Alternate-universe Batman expresses the hope that Justice League altering history so Vandal Savage loses World War II would prevent his parents' murder. Superman [[note]] the only member of the League currently aware of Batman's true identity and the DeathByOriginStory of his parents [[/note]] pauses for a second, then cautiously says he cannot promise that.

* DramaticIrony: When he learns of the time-meddling, Alt!Batman asks if setting things right will ensure his parents, who were killed by the regime, won't be gunned down. Superman knows damn well what the "Proper" timeline is like for Batman, which makes it ever more tragic.

* GloveSnap: Savage's TortureTechnican before going to work.
* GodzillaThreshold: Superman himself says, "All bets are off" on seeing just how close the Allies are to losing, causing the League to break their No Killing rule.

* AllGermansAreNazis: Subverted, Wonder Woman helps an American secret agent rescue an undercover spy and crypto agent from a Nazi prison. The spy turns out to be a native German working against the Nazi regime.

* MistakenForAfterlife: When Wonder Woman saves Steve Trevor the first time, he briefly thinks he's in heaven and she's an angel.

* ShootTheDog: In the middle of a retreat, Green Lantern tells Hawkgirl to leave him behind so she can carry wounded soldiers out in his place. She does so without argument.

* YouHaveGotToBeKiddingMe: Alt-Batman says, "You're joking!" when our heroes don't know the identity of the GloriousLeader with [[{{Egopolis}} his face up on posters all over Gotham]].
