Suzie Su was introduced into the DCnU after the 2011 relaunch of the DCU. She was created by Scott Lobdell.
Suzie Su lives in Hong Kong, and shares a past with Jason Todd aka Red Hood. They both met sometimes in the past and after Jason returns to Hong Kong, they've met again. Suzie and their two henchmen tried to kill Jason but before Suzie's Henchmen could draw their guns, Jason shot them and Suzie. She appears again, having survived their last encounter.
