Dark Eidolon was born of the sheer evil & darkness present in Gotham. He is a shadow, a thought, and moves at similar speed. Being created of evil at the base level he is able to manipulate matter at an atomic level. About the only thing to reveal his presence in the darkness is the red glow of his eyes.
