Now that this is out we're bound to get a sequel in a few years. This one already had Riddler, Penguin (I'm sure he'll be back) and Catwoman. Who from the Rogues Gallery would be a good fit for the sequel?
Joker? They hinted at him at the end, although they'd have big shoes to fill.
Two-Face? Maybe have him more like the comics (where he's a mob boss) and replace Falcone?
Black Mask? He could also be trying to replace Falcone.
Ra's Al Ghul and the League of Shadows?
Bane?
Poison Ivy? (She's too cartoony for this universe IMO)
Mr. Freeze? (Same)
Others?
I'm kind of thinking they should build up Joker a bit more (similar to how the MCU did Thanos) before making him the primary villain. Some of the other villains are a bit too silly for the universe.
I think Two-Face or Black Mask would be a good fit. Could also see the League of Shadows working.
