9. “Sunday Bloody Sunday” (Issue  37)

Gotham Central didn't usually cross over with the regular DC universe. "Sunday Bloody Sunday' was the big exception.

The penultimate story in the series, this one showed Detectives Crispus Allen and Renee Montoya trying to navigate the insanity that was 2005's Infinite Crisis. Magical beings drop from the sky, C-list supervillains run rampant on the streets and the skies quite literally run red.

The DC Universe can be a scary place and SBS really exemplifies that. As Allen struggles his hardest to get Montoya home after she's injured by a magical phenomenon, the world turns itself upside-down in his path. It's harrowing and intense and it's only one issue. Seeing these characters who, for the entire preceding series we have seen kicking butt and taking names, really out of their elements is existentially terrifying. I mean, when Captain Marvel falls out of the sky fearing for his family's lives, what hope does a police detective like Allen have?
