The Daughter of immigrants from the Dominican Republic, Renee graduated with top honors from the Gotham City Police Academy. As a beat cop, she single-handedly apprehended Mr. Zsasz. Officer Montoya further proved her capabilities under the command of Commissioner Gordon and his late wife, Lt. Sarah Essen Gordon, the latter awarding Montoya her Detective's Shield. Montoya's loyalty to Gordon was evident during Gotham's lawless No Man's Land, when she stayed in the quake-ravaged city to help restore order.

During this time Renee formed a friendship with the criminal Two-Face. She was able to reach the kinder 'Harvey Dent' persona, and he fell in love with her. However, Two-Face was still mentally unstable. Believing that the only way to have her was by taking everything else away from her, his more sinister side later outed her as a lesbian to the public and had her framed for murder. He then had the bus carrying her to prison attacked and kidnapped her, making it look like she had escaped. When Renee discovered that it was Two-Face who was behind everything, and that he did it because he was in love with her.

Two-Face then became more unstable and the two fought for control of his gun. If Batman hadn't arrived in time, it would have gone off and killed one of them. Two-Face was put back in Arkham Asylum and Renee was cleared of all the charges. Her life was still in chaos, however, especially her family; while her younger brother knew about her sexuality, her very religious parents didn't, and disowned her upon discovering the truth.

During the gang wars, Montoya and Allen were ambushed by the second Black Spider. To save both himself and Montoya, Allen gunned the villain down. A corrupt crime scene investigator named Jim Corrigan stole and sold the bullet that killed Black Spider on the Internet. To prove that Allen killed in self-defense, the GCPD needed to recover the bullet. In her pursuit of the bullet, Montoya clashed with Corrigan, eventually beating the name of the buyer out of him. Allen was cleared, but Montoya's obsession with exposing Corrigan escalated from there.

Allen noticed his partner's obsession and gradual change in overall attitude and behavior, and tried to persuade her to let the Corrigan issue drop. Montoya refused, so Allen began his own independent investigation on Corrigan, thinking that is he could get Corrigan exposed and brought to justice, it would help halt Montoya's downward spiral. He started to build a case against Corrigan, when he came upon one of his informants on Corrigan murdered. He was attacked, and shot fatally in the back by Corrigan.

In the GCPD's investigation, they failed to build an airtight case against Corrigan, who had a fake alibi provided by his girlfriend and paid off the officer who had loaned him the gun he used to kill Allen from the gun locker. Corrigan walked, and Montoya took it upon herself to bring him to justice. Tracking him down at his girlfriend's apartment, Montoya beat his girlfriend unconscious and drew a gun on Corrigan. He begged for his life, and Montoya ultimately couldn't pull the trigger. She walked out of the building and quit the GCPD the next day, disgusted and broken.
