The Torments of Owlman
Who are these shadowy figures that whisper-call to him? Are they demons sent to torment, flitting just outside his conscious mind? Perhaps the benevolent spirits of his ancestors come to praise him, or the ghosts of the future selves that could be, returned to mock him. Savior. Failure.
Don't worry, Owlman - you just keep drinking that rye and everything's gonna be fine. I promise.
