Batman Vol.1 #580
For the third time, Batman runs into Orca - this time at the Gotham Aquarium. Batman understands that Orca sees herself as some kind of Robin Hood, but he cannot overlook the fact that people died because of her actions. When one of the large water tanks in the aquarium breaks, Orca is able to flee once again. Interestingly, the wheelchair of Dr. Grace Balin lay in that water tank as well.
