Mockingbird

A shadowy presence lurking at the heart of DC's Villains United, this Mockingbird emerged in 2005 from the creative minds of Gail Simone and Dale Eaglesham — right in the thick of the modern era's sprawling Infinite Crisis saga. Operating in a corner of the DC universe populated by the likes of Green Lantern, Firestorm, The Flash, and the dangerous Knockout, this character carries the intrigue of a figure who works from the shadows. With only a handful of catalog appearances, Mockingbird is a rare, enigmatic piece of Infinite Crisis history — the kind of deep-cut discovery that makes digging through event comics so rewarding.
