Roman Sionis

Roman Sionis is the owner and proprietor of the "Black Mask Club" in southern Gotham. He's a narcissist with the attitude of a spoiled child. Roman is the sole owner and CEO of Sionis Industries, a steel milling company that exports and sells all over the world. With his status as a billionaire, Sionis enjoys the heights of human pleasure and material possession. In addittion to his wealth, Roman is also a notorious crime boss and money loaner. He works with his right hand man, assassin, lap dog, and boyfriend, Victor Zsasz.

Personality
Roman is a narcissist first and foremost. His first concern is always himself, and he requires near-constant reassurance from those close to him. Roman is addittionally emotionally volatile, quick to snap and turn to violence at the nearest oppourtunity. Roman has little concern for innocent bystanders or human life outside of his own little world.

Roman is a bit o a germaphobe, demanding pristine, perfect treatment with everything he owns. Roman is one to just through entire pieces of furniture away on a whim, knowing he can just buy a new one. He carries this same attitude with human life.

Roman is also a hedonist. He views himself as a connosseur of the finer things in life, spending his extravagant wealth on antiques, pieces of art, and cleanly tailored clothes. In addittion to his spending habits, Roman eats only the finest and most expensive foods, known to narrate to himself and Zsasz about the detailed nature of every meal he eats. He addittionally pursues sexual pleasures, though only with his right hand man. Roman's possessive nature shines through into the things he owns, living by the belief that he can do whatever he wants with the things he owns (including Zsasz, who is delighted to hear this).

Victor Zsasz
Roman and Zsasz are two horrible people in a horrible codependent relationship that both revel in. While Roman loves to inspire fear, Victor loves to kill and torture. Roman needs someone to feed his ego and care for his volatile nature. Inturn, Roman keeps Victor safe, and lets him kill as much as he wants.

Harleen Quinnzel
Roman Sionis despises Harley Quinn with a passion. Harley, while in a relationship with The Joker, was begrudgingly safe in the eyes of Gotham City's criminal underground, which lead to Harley drinking around and abusing her status as "Joker's Girl". Roman, annoyed that Harley was a giant hole in his already massive pocket, could not WAIT for the oppourtunity to kill her. He serves as one of her most consistent villains, constantly trying to kill her.
