The first issue of The Dark Knight III: Master Race was published on Wednesday, and continues a storyline started 29 years ago by the writer and artist Frank Miller, in his classic The Dark Knight Returns.
The issue came in the week a Chicago police officer was charged with the murder of a black teenager, and a year since riots engulfed Ferguson after officer Darren Wilson killed 18-year old Michael Brown.
In Master Race, Batman appears focused on reforming the criminal justice system - though so far he prefers to enact that reform with his fists.
Issue No 1 opens with a young, unarmed black man fleeing from Gotham cops, who draw their guns to shoot before Batman arrives and - kapow! - knocks them senseless. It ends with the hero being brutally beaten by a group of uniformed officers, the Independent reported.

"It needs a 'Zorro', a criminal who can fight for the innocent civilians. The status quo cannot be trusted," he had said.
Miller, who says he is already planning a fourth Dark Knight series, co-wrote Master Race with another eminent comics writer, Brian Azzarello.
