for Detective Arnold Flass in Batman: Gotham Knight (2011)
Suggested by blockbuster53

Batman operates in Gotham as a feared urban myth during a collapsing gang war between the Falcone and Maroni families. As organized crime tears the city apart, District Attorney Harvey Dent rises as Gotham’s symbol of hope, working alongside Lieutenant James Gordon in a fragile alliance against a deeply corrupted GCPD. Inside the department, Detective Harvey Bullock initially hunts Batman as a criminal, Captain Branden leads militarized SWAT crackdowns under Commissioner Loeb, and Detective Flass secretly serves the Falcone mob. Batman escalates his campaign from street-level vigilantism to dismantling the mob’s financial and political networks, drawing fear from criminals and uneasy attention from the public. Catwoman moves through the chaos as a shifting wildcard, while the Joker appears briefly as a disturbing inmate inside Arkham Asylum. As Dent prosecutes the mob, Flass smuggles acid into a courtroom during a trial involving Sal Maroni, triggering a catastrophic attack that scars Dent and shatters his psyche into Two-Face. Flass is killed soon after as Two-Face’s first act of vengeance. Two-Face unleashes a violent purge against Gotham’s criminal and corrupt leadership, culminating in a final confrontation where Batman stops him but cannot restore Harvey Dent. Commissioner Loeb is exposed and removed, Gordon becomes Commissioner, and Bullock begins aligning with reform. Gotham cautiously accepts Batman as a necessary force, though still fearing what he represents. Mid-Credits: Bruce Wayne receives two tickets to Haly’s Circus from Alfred, hinting at a future shift in his path beyond Gotham’s shadows. Post-Credits: In orbit, LexCorp satellites detect an unexplained burst of solar energy over Kansas, registering an anomaly beyond known science.
