Aaron Herbst was a caretaker of Inque when she was held captive.
Aaron Herbst was a former technician at Gotham Cyrogenics. Over a six month period, Herbst displayed abberent behavior and began talking to their most dangerous assignment, Inque. Gotham Cyrogenics' owner, Mr. Chandler fired Herbst upon security tape review. However, Herbst wasted no time and used his security clearance to break into the facility and freed Inque. Inque's human DNA was badly damaged and needed treatment. She manipulated Herbst to help her break into Fulton Labs and steal the needed components, in exchange for being given similar polymorpic powers. Though Aaron aided Inque by knocking Batman out with a crane, Inque only administered half the treatment and left him as a bizarre monstrosity. He distracted Inque long enough to allow Batman to escape and damage the roof to let in the rainstorm and wash Inque away. Herbst was then imprisoned at Gotham Cyrogenics for his crimes.
