Danny Bonaducci needs a cameo too. He can be Killer Croc.
I agree with the guy who said Conroy should have a cameo, as a police officer or as a father to a boy Bats saves, he should talk in his Bat voice or something.
like if they had Harvey Dent get a call and they mentioned a Ms Isley need to talk or something that would be a serviceable cameo.
When it's "I'm Batman and I wanna stop the Joker..."
"Hi, I'm Killer Croc!"
it's a bit wtf

one word and a ? at the end: crossover?two words: ironman
