Renee Montoya started out as a uniformed police officer. One of her first assignings was a drug bust that ended up going wrong. She was suspended from the force and accused along with Harvey Bullock and officer Wilkes of being on the take. When she figured out where the drug ring was hiding she investigated even though she was suspended. There she found Batman tied up. After Batman freed himself she helped him arrest the drug lords. Soon after she was put back on active duty by Commissary Gordon. She was later promoted to sergeant, and later transferred to Special Crimes, where she was promoted to detective.
