Fan Casting(DCEU) Superman/Batman: Public Enemies (2016)

It's been nearly two years since Superman's colossal battle with Zod devastated the city of Metropolis. The loss of life and collateral damage left many feeling angry and helpless, including crime-fighting billionaire Bruce Wayne, who had recently lost Jason Todd. The Batman had slowly gone a dark path through those 2 years to the point where even the GCPD is unsure if he is a ally, which Clark is concerned on. However, after the attack on the Capitol; Bruce is convinced that Superman is now a threat to humanity and now he embarks on a personal vendetta to end him; possibly being the first kill he will ever commit. Behind the scenes, the conniving Lex Luthor launches his own crusade against the Man of Steel with the Proto-Amazo; but Bruce is on the case with a mysterious woman aiding him.
