Janus Cosmetics is a company based in Gotham City and owned by the wealthy Sionis family. After Mr. Sionis and his wife perished in an accident, the company was left to their son, Roman Sionis, to take over as its CEO.


  • Janus was the Roman god of beginnings and endings, who had a double sided face. This is a probable reference to Two-Face.
  • A Janus cosmetics sign can be seen in the Pretty Dolls Parlour.
