The first game ends with Batman enlisting the help of the Justice League’s alternate-universe equivalents and the Man of Steel being escorted to his jail cell in kryptonite-imbued chains. The second game introduces Brainiac to the Injustice universe. His desire to colonize Earth forces Batman to release the Last Son of Krypton (and his One-Earth cohorts) for a temporary alliance, realizing Brainiac couldn’t be defeated without Superman’s assistance. Injustice 2 concludes with another overdue civil war with Brainiac captured, the two parties scuffle among themselves trying to decide on the best course of action. If the player chooses Superman, Clark Kent reinstates his Regime, restores the cities, eliminates Brainiac, and blackmails Supergirl into potentially defecting from Batman’s side. If the player chooses Batman, Brainiac is kept alive a while longer, Superman is depowered and banished to the Phantom Zone, and Supergirl joins the newly reformed Justice League. The story of Injustice 3 depends largely on whichever ending NetherRealm decides is canon. If Superman wins, the game will probably involve Batman and the Insurgents rising up one more time against the One-Earth Regime.

Gods Among Us already did that, however, and NetherRealm isn’t known for repeating old storylines.
