These dark Batmen are scary guys indeed. The this issue opens on Earth 0 but quickly jumps to Cyborg at the monitors of the Watchtower. Dark Batman takes down Cyborg quite easily. A lot of this issue is flashbacks throughout the multiverse. The art is lush yet gray, almost washed out really highlighting the different settings in the multiverse and that this is a DC universe event, but very much a Batman story. Bane Batman and Alfred all look super under this art team.
Cyborg was down but not out as the narrative returns to present he continues to fight Batman. It doesn’t go well.
The dark Bat League look and seem absolutely horrific and the creative team has done a good job making Metal fresh, while paying homage to the long history of the multiverse's history.
