Fan Casting Black Mask/Roman Sionis in Red Hood

Would be the target of a lot of Joker's attacks as the Joker seeks to take control of Gotham. Would probably ally with Batman and Red Hood and give them information about where certain supplies of the Jokers might be. Weapons caches, places he might make the Joker toxin. Would do this until Barbara eventually awakes. Would say how when he was in Arkham, he heard a lot of rumours about the Joker running things from inside.
