Rise to power[]


A year after Lew Moxon's death Black Mask took over his criminal empire and began to run the Gotham City underworld. Black Mask was just as ruthless if not more so than Moxon himself. Black Mask wasted no time attempting to kill Batman and lured him into a trap at the Gotham City Mall. There Black Mask was holding hostages and planned to kill Batman in an explosion. Batman was able to take Black Mask down but Black Mask said that unless he released him he would detonate a bomb and kill the hostages. The Dark Knight was forced to let Black Mask go in order to save the hostages.
