The Broker

Gotham City Sirens brought some of DC's most cunning and dangerous figures together under one roof, and The Broker is a Modern Age creation who carved out a niche in that shadowy corner of Gotham. Debuting in 2011 courtesy of writer Paul Dini and artist Andres Guinaldo, this character moves through a world populated by the likes of Catwoman, Pamela Isley, the Riddler, and even Batman himself — rarefied company by any measure. With only a handful of appearances concentrated in the Songs of the Sirens and Union collections, The Broker is a rare find for readers who love digging into the deeper cuts of Gotham's criminal ecosystem.
