Roman Sionis, also known as Black Mask, is a brutally sadistic crime boss who seeks to control Gotham City’s entire criminal underworld.
Most of Roman’s life is shrouded in mystery but what was known was that he despised his family due to the lack of respect they gave him. He wasn’t given everything he wanted like most people believe when they hear of him he had to work for what he has. At some point he was cut off from his father’s wealth from the Janus Cosmetics and his father took control again. After that he delved into Gotham’s criminal underworld to make a name for himself, along the way he met Victor Zsasz who became his right hand man and lover.
At some point Roman rose in the criminal underworld and crossed paths with many crime bosses such as Joker, and his girlfriend Harley Quinn at the height of their power. To which they became acquainted and grew to respect each other. Roman met many of the other crime bosses who eventually went to be on the mysterious Batman’s radar such as Carmine Falcone, Riddler, and Penguin.
