Batman Arkham: Reign of Brainiac

(This is a rewrite of the game Suicide Squad: Kill the Justice League as I feel Batman and the league were done dirty, so this is a rewrite where Batman is the main character again. This takes place five years after the events of Arkham Knight.)

Five years ago... The Batman died. But something else arose in its place. Haunting the criminals of Gotham.

Unknown to Gotham, Bruce had faked his death after his identity was compromised and now operates with even more secrecy.

But when a collector of worlds attacks the city of Metropolis and turns the Justice League against those they protect, Batman is forced out of the shadows to stop this reign.
