|~ Batman to Owlman|
Owlman is the true main antagonist of the direct-to-DVD animated feature, Justice League: Crisis On Two Earths.
He is voiced by James Woods, who also voiced Hades in Hercules, Falcon in Stuart Little, Dr. Phillium Benedict from Recess: School's Out (who ironically had a plan to end Summer Vacation, the culmination of which would have resulted in a frozen earth very similar to the one that Owlman ultimately ended up dying on), and even a fictional version of himself in Family Guy.
Owlman is a member of the Crime Syndicate on a parallel Earth, and he is romantically involved with Superwoman. His backstory isn't made clear, other than he described himself as never having been good due to "being human." He learns about the Multiverse and, due to his misanthropy and nihilism, seeks to destroy the Multiverse by destroying Earth Prime, in order to make "the only choice that really matters", believing that the other choices that humans make are just meaningless illusions and that lead to "the source of the cataclysm". With the help from the other members of the Syndicate, he is able to construct the Quantum Eigenstate Device (QED). While they were constructing the device, Owlman, along with Superwoman, secretly search for Earth Prime.
He is eventually able to find Earth Prime, so he teleports both himself and the QED there. With help from the Crime Syndicate, an alternate-reality version of Lex Luthor, and the Justice League, Batman teleports to Earth Prime to confront Owlman. The two fight, during which Owlman questions why Batman decides to protect humanity despite the two of them being very similar to one another. Batman replies that, while they are both similar, there is one difference: Specifically, when the abyss gazed back at them when they looked into it, only Owlman "blinked" in response. In the end, Batman teleports both the QED and Owlman to a frozen, uninhabitable Earth before the QED detonates. Owlman has the option to abort the explosion, but instead, he calmly states "It doesn't matter." As the QED detonates, both Owlman and the frozen Earth are wiped out.
- Technically, Owlman's declaration of the source of the cataclysm on Earth Prime being man as it always was in his final confrontation with Batman is incorrect, because one of the alternate Earths he mentioned when explaining his nihilistic motivations to Superwoman was explicitly stated to have occurred because fish never became brave enough to crawl onto the surface and thus prevented the evolution of man as a species, meaning man couldn't have been responsible for that reality as man didn't even exist during that time.
- Owlman's armor appears to give him greatly enhanced strength, since he is able to directly trade blows with Wonder Woman for brief periods.
- Owlman's true name and identity is never stated here, but he appears to be a rough equivalent to Bruce Wayne, when dialogue between himself and Batman indicates the same tragedy drives them. In some continuities, Owlman is Bruce Wayne of his Earth; in at least one other, he is Thomas Wayne, Junior, Bruce's older brother, who witnessed the loss of his mother and younger brother at the hands of corrupt police, after which he was raised by Joe Chill.
