Scarface Gang

History
Scarface and his Ventriloquist own the biggest, independently operated organized crime syndicate in Gotham. Though they have worked with the Masterminds in the past, they typically oppose them. Peyton Reily runs the Riley Crime Family (aka: "The Irish") and when in possession of Scarface, she also has the loyalty of Scarface's organization.

Arnold Wesker and Sugar (or maybe it is Scarface himself...) do not recognize the Masterminds and thus their gang are usually at war with one or more of the Masterminds, except Joker. Scarface doesn't like to mess with the Clown, ever since the Clown put his hand up the dummy's backside, Scarface keeps a wide berth from that psycho.
