Hailing from Earth -44 in the Dark Multiverse, this Dark Knight was born when an all-powerful A.I. program designed by Cyborg began to misinterpret its coding to homicidal ends. A cybernetic nightmare, The Murder Machine is a metallic mangling of the technological power of Cyborg and the tactical brilliance of Batman, formed by ever-changing nanobots.

Bryce Wayne of Earth -11 harbored a deep hatred of the Atlanteans for their role in the death of her beloved, Sylvester Kyle. In a quest to avenge Kyle, she spliced her DNA with that of an Atlantean, becoming a super-powered Dark Knight called The Drowned capable of breathing and fighting underwater.
