Differences with the Source Material
The film adapts primarily the first volume (sometimes referred to as "Injustice: Year One"), though elements of both the games and comics are added. However, multiple differences with the story and events can be found, the following being the most notable:
- The Flash dies in a trap set by the Joker.
- Martha Kent has died before the events of the films, with the government only targeting Jonathan.
- Lex Luthor is absent in the film, the character serving as a mole for the Insurgency against Superman's regime.
- Dick becomes "Deadwing" after his accidental death rather than taking on the Deadman identity. Damian also remains in the Robin identity.
- Ra's al Ghul is the only supervillain to ally himself with the Regime.
- The heist from the Fortress of Solitude is a Red Sun Cannon as opposed to strength-enhancing pills.
- Plastic Man rescues Mr. Terrific from prison as opposed to his own son.
- Ra's' betray of Superman and the battle with Amazo are all original content, though inspired by events from Injustice 2.
- Damian's battle with Ra's and help from Grayson's spirit are partially taken from a similar encounter in Injustice: Year Five, where Robin had fought.
- Superman defeats the Earth-One Superman as opposed to being defeated. He only surrenders due to an alternate Lois being brought to the universe, who forces him to confront his actions.
