History
Black Mask has a history with Miss Masquerade (Elizabeth), she used to work for him. The two became rather close, but things went sour when her father was killed in the crossfire by one of Black Mask's men, so she stole from him and left.

While in Gotham he was personally involved in a bank heist that was interrupted by a severely sleep-deprived Melius, Melius was able to take out all his goons rather quickly in the cover of smoke, but he mistimed how long the smoke would last due to lack of sleep, and Black Mask shot him. He used this distraction to escape, and Melius was rushed to the hospital, which resulted in his identity being revealed.

One fateful night, Elizabeth had heard of Black Masks' return. The question was to fight or run... And she chose to fight. Still filled with the bitterness of her father's death, she sought revenge and went undercover as one of his henchmen, Leonid. Making her way to his office however, there was hesitation and in this moment the young vigilante had made her first mistake. Not only did she confess her feelings to her ex-boss, she had kissed him. Regret, happiness, confusion and joy constantly switched around in her head, reminding her of her current loved one; Kyle Conner. She couldn't do this. So with a heavy heart-and to Miss Masquerade's surprise-Black Mask had let her go. Now, they were even. To this day, she wasn't sure what came over her... But sometimes she debates about going back.

Red Hood has been causing trouble for Black Mask. This prompted Roman to start a League of Villains with him as its head.
