Sy Borgman is a former agent for the U.S. Government and an ally to Harley Quinn. In his past, he was heavily injured when he risked his life to stop a dangerous terrorist group. He was then enhanced with bionics and his damaged body parts were replaced with cybernetic limbs, giving him the nickname Sy-Borg. He later became a good friend to Harley Quinn and a roommate at her apartment. Sy Borgman was created by Jimmy Palmiotti, Amanda Conner, Chad Hardin and Stéphane Roux, first appearing in Harley Quinn (Volume 2) #2. (2014)
