Initially, the cover of Batman #36 was generic and essentially nondescript, due to the possibility that providing a more visually striking cover could spoil certain story elements. Nevertheless, the real cover is available for your viewing pleasure, and is rather visually arresting. It features a Joker-ized Superman who bears bloody hands and teeth clenched in a psychotic smile.
Batman #36 Cover:
Batman #36 is the second part of the “Endgame” story, which DC says is “steeped in mystery” (while Superman’s hands appear to be steeped in blood).
According to CBR, Scott Snyder made a point of comparison between “Death of the Family” (Snyder and Capullo’s previous Joker story) and “Endgame”:
“This one is meant to be like a kaleidoscopic use of color and art. Where the first one was black, horror, grisly; this one is, Joker’s just sort of there, taking everything he wants. So there’s a sense of scope to it that I think will be reflected in the art and coloring.”
Batman #36 is scheduled to be released on November 12, 2014.
