Joseph Morgan (Earth-8026)

"See, Batman. recently I been strugglin'... I'm just an ol' croc tryin' to get by in a cruel world, tryin' to make a livin'... surely you gotta understand that. This city's got much bigger problems than little ol' me, just look at the Joker, or the Scarecrow, they're the real menaces! So why can't you just leave me in peace? I'm not hurtin' nobody who don't deserve it. And let me tell you, you're gettin' real close to bein' one of those people that deserves it."
