Gotham: 10 Most Terrifying Villains So Far

10. Richard Sionis

Who He Is: Richard Sionis was a successful businessman, owning a competitive financial firm in Gotham so prestigious that prospective workers would do just about anything to secure a job. A creative man of means and with bizarre interest in historical masks, Sionis develops a rather unique system of managing his employees. Instead of arranging for corporate retreats and icebreakers…well, Sionis forces them to participate in an underground fighting ring to keep their jobs.

What He Did: After the death of one of the participants in his fight club draws the attention of Detective Gordon, Sionis abducts Gordon and forces him into his corporate arena to fight for his life. After Gordon easily defeats a handful of goons, Sionis dons a black mask and enters the fray himself.

Current Status: Jail. Sionis is put under arrest after Gordon bests him in battle and the SCPD comes to the rescue.
