@Deranged Midget: True. However, a baby wouldn't be able to do much damage.
The third game will probably be Batman Beyond-related.
At least, I'm betting it will.
Doubtful, they hinted at Hush possibly headlining as one of the lead villains in the side missions.
Hush really isn't that popular of a character in the DC comics, though...I had never heard of him before I played the game...of course this is probably because I have only really been a comicbook fan for about a year...
The whole thing with this is basically ideas about what would happen IF James Gordon Jr. did become the Joker in some odd alternate universe. How would it affect his family? How would Barbara react? How would his father react?
This is completely spit balling right now, but what if the Arkhamverse and New 52 universe merged, I wonder what would happen if James Jr. became the next Joker? I know the "Joker" isn't really a mantle, but what if this happened?
