Set two years after the
canon ending of Human Revolution, the established social unrest
of the
first game has since devolved into chaos, as augmented humans are now seen as a violent threat towards society.
Granted, there are other possibilities for the Arkham Knight's true affiliation, such as the Suicide Squad and Amanda Waller, which is another possible explanation for Rocksteady making Origins
canon due to the Squad and Waller
first being shown coming together at the
end of the
game.
