Janus Cosmetics was a makeup company owned by the wealthy businessman Charles Sionis. His son Roman Sionis killed Charles and took over the company, then ran it into the ground with bad management and poor investments. The company was bought out by Lucius Fox at the Wayne Foundation under the condition that Roman step down as President. This caused Roman to become the super-villain Black Mask and swear revenge on the Waynes.
