Not sure if that's the final boss with Catwoman as I haven't played anymore with her. I haven't, but has anyone tried to go back to Poison Ivy? That could always turn out to be some sort of boss battle seeing what Catwoman did to her plant near the end.
Heh, yeah, was trying not to spoil the action of the event for any who didn't get there yet, but AFAIK that's her final thing in the story mode leading up to the free-roaming portion of the game. Not sure if she has any specific side-stories like Bats or just the 4 "episodes".
