- - Arnold Flass

Detective Arnold Flass is a former member of the Gotham City Police Department, where he acted as the partner of then Sgt. James Gordon.

Early Life
Arnold Flass started working for the Gotham City Police Department as the partner of Sgt. James Gordon. However, while Gordon was a "by-the books" public servant, Flass was corrupt much like the rest of the department, and worked very openly as an enforcer for crime boss Carmine Falcone, enjoying torturing criminals who opposed Falcone's Roman Empire.

The Batman
During a normal routine work, Flass was patrolling alongside Gordon before he stopped to buy a chocolate bar, but not before stealing money from the cashier, which made Jim look disgusted. Flass' only response was offer a bit of it for his partner, who refused at the same second. This led Arnold to state the other cops at the GCPD took Gordon's nature as a non-corrupt police officer to be possibly threatening to their operations.

Flass and Gordon arrived at the scene where the recently arrived vigilante Batman brutally beat up and apprehended Carmine Falcone and three of his henchmen. While they could not locate the aggressor, Falcone and the criminals were promptly arrested by the GCPD and sent to Arkham Asylum.

After another shift, Flass stole cash from a hot dog vendor and ran to an alley. However, the corrupt policeman was suddenly taken off the ground by Batman with his Grapple Gun, being pulled ten stories to a building. At the building and tied upside down, Batman brutally interrogated him about a new drug that emerged in Gotham. After Flass told him everything he knew, Batman released him to the ground, before pulling him back and taking him down.

Battle of Arkham Asylum
He found himself present at Arkham Asylum alongside James Gordon two nights later, following Batman's attack on the installation and a confrontation with the Scarecrow. Flass had the GCPD's SWAT team prepared at many of Arkham's entrances to neutralize the Batman, but he was easily able to defeat them with superior martial prowess. After escaping the cops with the Tumbler, Gordon and Flass were left out amazed by the vigilante's intelligence and resources.

Battle of Gotham City
Later on, while present at The Narrows, Arnold was infected with Scarecrow's Fear Toxin after it was released in the slums of Gotham City, and in his nightmare he believed all those near him to be demons. This led him to kill two people, before he was restrained by Gordon.

Incarceration
Afterwards, Flass lost his license after his illegal activies were made public, and then incarcerated at Blackgate Penitentiary.
