In his Earth, Thomas Wayne as Batman fought crime in Gotham city by killing criminals like Bane, the Riddler, Kite-man, etc. He was about to do the same to Catwoman but she somehow got him to trust her and reveal his secret identity, even making her his partner in fighting crime. Later on he’d say she reminds him of his dead son Bruce. Catwoman would later be shot and killed by that Earth’s Joker, Martha Wayne.
