- You may have repented your rebellion, you may have renounced the campaign to seize creation, but we have not! As you have taken a human vessel, so have we. Your plan to reconcile good and evil is known to us. It is heresy. We spurn it. And when your human vessel is destroyed, Batman, your work will finally be undone. For you, all is now lost.

He captured Lucifer's host, Simon Petrarch, and attempted to sadistically kill him, only to be rescued by his guardian angel, The Robin.
