History Script / JusticeLeague2

* AdaptationExpansion: ''Project Justice League'' adds various DCEU characters to the story that weren't part of the original outline at the time, but various projects that were greenlit and filmed after the storyboards were made. This includes characters from [[Film/SuicideSquad2016 Harley Quinn, Rick Flag, Katana, Captain Boomerang, Killer Croc]], [[Film/SHAZAM2019 Shazam]], [[Film/TheSuicideSquad Bloodsport and King Shark]], [[Film/BlackAdam2022 Black Adam, Doctor Fate, Hawkman, and Atom-Smasher]], [[Film/TheFlash2023 Supergirl]], Batgirl, and Film/{{Blue Beetle2023}}. Deathstroke also makes a cameo in a Knightmare scene that he otherwise didn't participate in. It also gives Martian Manhunter, who was only introduced in ''Zack Snyder's Justice League'', prominence in the final battle instead of just having a cameo at the end of the outline, alongside making John Stewart a part of the Green Lantern cavalry at the end. The video also adds dialogue that was not present in the original outline.

* SuperpowerfulGenetics: Averted. Bruce Kent somehow does not inherit his father's Kryptonian powers -- which is part of the reason why he becomes the second Batman.

* HeroicSacrifice: In ''Justice League 3'', Lex Luthor pulls one off after realizing that Darkseid wants to destroy the human race. He nukes Darkseid's capital ship with himself on it.

* DownerEnding: ''Part One'' ends on a depressing note, with a pregnant Lois, Wonder Woman and Aquaman dying, Superman being brainwashed, Cyborg being crippled, and Batman and Flash escaping unscathed and going into hiding with their remaining allies.

* AdaptationNameChange: In the comics, Superman and Lois' son is named Jonathan Samuel Kent, after his adoptive father and her father respectively. In this movie, he would be named Bruce Jonathan Kent, after his father/late godfather and his adoptive father's father/biological father's adoptive father depending on the version of the story.

-->''Darkseid's full scale invasion begins -- and it's too much for the Justice League to handle on their own -- but they won't have to. Led and inspired by Superman, the countries of the world come together: armies, air forces, navies. Wonder Woman and her mother lead the Amazons off Themyscira to join the war. In the oceans, Aquaman pleads to the Seven Kingdoms, declaring there is an eighth -- the surface world -- and they must be allies, not enemies. The Seven Kingdoms rise to join the Amazons and the surface. The entire world becomes a Justice League.''
