"Ain't you seen Serpico, honest cops are usually the ones who get shot in the face."

- Brett Mahoney

Early Life
"We've been enemies since we were four Brett."

- Foggy Nelson to Brett Mahoney

Brett Mahoney was born and raised in Hell's Kitchen. Since he was a young boy, he has had a strong friendship and rivalry with another local boy named Foggy Nelson. When he grew up he became a officer of the New York City Police Department.

Cigars for Mother
"Please stop giving my mom cigars, Foggy." "What? She'll outlive us all."

- Brett Mahoney and Foggy Nelson

While on duty Mahoney ascended the stairs of the in Hell's Kitchen. As he walked along the streets he was greeted by his childhood friend and rival Foggy Nelson, now working as a lawyer. Nelson handed him a package of cigars for his mother Bess as a gift. While not happy with Nelson giving his mother cigars he did accept them. Before continuing his journey he indirectly promised Nelson to give him a heads up when an interesting case arrises that Nelson's law-firm, Nelson and Murdock could get involved with.

Karen Page
"Homicide, female suspect found at the scene, definitely qualifies as interesting." "She hasn't been charged yet?" "Assistant D.A. hasn't made the call yet."

- Brett Mahoney and Foggy Nelson

Later that evening Mahoney called Foggy Nelson, informing him about a homicide case involving a single female suspect named Karen Page who had seemingly murdered her co-worker with a knife in her apartment. Nelson and Murdock took on the case and quickly proved Page to be innocent of the crime and they even then hired her as an assistant.

Elena Cardenas
A few days later Mahoney was serving as the desk sergeant in the station. One of the people who visited the desk was Foggy Nelson's law firm partner, Matt Murdock. Murdock told Mahoney that they are working on a case from a friend of Mahoneys mother. Mahoney, realizing that Murdock was talking about Armand Tully, who was attempting to evict tenants from their homes, told Murdock that everything Tully does stays just inside of the law, so there was nothing the police could do. Mahoney then went to see if he could find any copies of the complaints made against Tully and to see if it was possible for Murdock to talk with some of the officers who took them.

Hospital Duty
Mahoney was tasked with controlling everyone who came to visit Detective Blake, one of the police officers shot during a raid, seemingly by a masked man who had been working as a vigilante in Hell's Kitchen. Since the shooting Blake had been in a coma. One of these guests was Carl Hoffman, Blake's partner who had come to visit his friend. Before allowing Hoffman to enter the room, Mahoney asked him to sign in before also checking what was in the bag - a meatball sandwich. Seeing nothing suspicious about Hoffman, Mahoney allowed him to enter the room. A few minutes later however, Mahoney heard a noise coming from the heart monitor inside Blake's room and he called out to Carl Hoffman to see if something was wrong. When Hoffman wouldn't answer their calls, Mahoney, together with a few other agents, attempted to open the door, which was blocked by a chair from the inside. When they were finally able to force the door open, they found Blake lying dead in his bed, having seemingly been murdered by the man in the mask and Hoffman is laying on the ground, unconscious having also been attacked by the vigilante.

Elena Cardenas' Death
When his mother's friend and Nelson and Murdock's sweet, elderly client Elena Cardenas was murdered outside her home by a junkie who had stolen her purse, Mahoney personally took charge of the case and phoned their offices to inform them of her death. Foggy Nelson, Karen Page and Matt Murdock arrived to identify the body. Mahoney explained what had happened to her and asked if she had any family left who could be contacted, they explained she did not and promised to take care of the funeral arrangements themselves. Both Nelson and Page cried over the death of their friend, while Murdock remained silent and still.

Encounter with the Masked Man
Mahoney was one of the first officers who arrived on the scene of a fire at a warehouse, which was discovered to be an illegal drug den run by Madame Gao where blind workers made heroin. As he explored the facility, Mahoney encountered the Man in the Mask, who was attempting to flee the scene. Mahoney raised his gun and attempted to arrest the man, but was quickly disarmed and knocked to the floor where the man told him he was not the bad guy before escaping.

Helping Nelson and Murdock
"The way things are going around here, I'm thinking about taking an early pension. Move my mom somewhere warm." "Be a shame. The only cop on the force we know for sure is honest."

- Brett Mahoney and Matt Murdock

Mahoney was approached by Foggy Nelson and Matt Murdock who requested any information Mahoney could give them about the activities going on at the Police Station. Mahoney reluctantly told them what information he had, although he noted that Murdock appeared to not be listening, he then told them that he was planning on retiring early. While working behind the desk in the police station, Mahoney was shocked to be approached by Detective Carl Hoffman, who arrived covered in blood. Hoffman told Mahoney that he wished to make a statement. Hoffman confessed that he had been employed by Wilson Fisk to ensure that the police never discovered his criminal activity, the explained that he had gone into hiding after murdering Blake and had been rescued and convinced to speak out by the Man in the Mask. Through Hoffman's confession, the FBI were able to arrest anyone connected to Fisk's criminal empire, including several corrupt police officers, whom Mahoney watched being arrested with a smile on his face.

Capturing Wilson Fisk
Wilson Fisk was arrested but soon escaped with the help of his soldiers who attempted to break him free. Fisk did not remain free for long as he was soon found by the Man in the Mask who fought him and knocked him unconscious. Brett Mahoney was the first on the scene and found Fisk lying on the ground beside the newly named Daredevil, now wearing a red and black costume complete with horns. Mahoney arrested Fisk and allowed Daredevil to go free.
