Injustice is a film adaptation of the comics and video game series of the same name. Taking place in an alternate universe referred to as "Earth-22", the film focuses on a civil war between both Superman and Batman. The film was released on October 19, 2021.


The story takes place on an alternate Earth in which the Joker has tricked Superman into killing Lois Lane, sending the hero on a rampage. This unhinged Superman decides to take control of Earth for its own good, leading Batman and his allies to attempt to stop him.


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.
