10The Dark Knights
Imagine if Batman could take over the powers and roles of all the members of the Justice League. Pretty sweet, right? Awkward, yes. Scary, yes. But still pretty cool. Now Imagine if all of those Batmen had one really bad day. That’s basically the idea behind the Dark Knights
of the Dark Universe that Bruce manages to unleash during the events of Dark Knights Metal. While they may not have been around for a long time, these Batman, including the Batman Who Laughs (a version of Batman undone by killing the Joker), have certainly caused some massive problems for the Bruce and the rest of the Justice League.
