Leviathan, the shadow organization enemy of Batman Inc. Leviathan, who has their own murder cult, and a penchant for killing Batman Inc members. Leviathan, who was thought to be led by Bruce Wayne’s ex Jezebel Jet…who is no longer among the living.
They’re the evil Batman Inc, for those who aren’t aware. They brainwash, they murder, they do all kinds of crazy ass Grant Morrison inspired stuff. And the reason why they hate Batman so much? Because he took something from their leader, something irreplaceable for which all hell must be unleashed in retribution.
He took her son.
Leviathan is Talia al Ghul
