Brett Mahoney is a character from the Marvel Comics universe. Brett has also recently appeared in the Daredevil TV series, which is part of the Marvel Cinematic Universe.


Brett Mahoney first appeared in the comics Marvel Comics Presents Vol 2 #1 (November 2007). He was a detective in the 27th precinct of the NYCPD and partnered with Stacy Dolan. \


Brett was born and raised in Hell's Kitchen. He had a strong friendship and rivalry with Foggy Nelson. He's an officer of the New York City Police Department. He gives Nelson & Murdock a tip that turns into their first case; defending Karen Page. Brett helped bring down Wilson Fisk.

Brett briefly encountered Jessica Jones, when she tried to confess to the murder of her neighbour. He and his fellow officers were mind controlled by Kilgrave, and Brett aimed a gun at his superior, Detective Clemons. Both Jessica and Kilgrave left the police station without any further incident.

After arresting The Punisher, Brett was promoted to Detective Sergeant. In this role he investigated the activities of the Hand, at great personal risk to himself and his family. Months later when investigating an attack on a Senator, Brett again encounters Karen Page, but this time he fails to capture Frank Castle (The Punisher).

Most of the fandom around Brett is focused on his MCU appearance. Brett is often a side character in fics. Similar to the role he plays in canon, Brett is often investigating a vigilante, usually Daredevil, or he is investigating the same criminal that Daredevil, or another vigilante, is targeting.

In some fics, Brett is often suspicious of his friends tendency to turn up at so many crime scenes, often in cases related to Daredevil. He may also become suspicious of Matt Murdock. In fics where Brett is a main character, secret identity reveals are common.



Examples Wanted: Editors are encouraged to add more examples or a wider variety of examples.


  • I Am Not Your Jim Gordon by WerewolvesAreReal, Teen Daredevil has been directing criminals to confess to Sergeant Brett Mahoney specifically. Brett would like an explanation for this, and the cops of Hell's Kitchen speculate.
  • a baker's mile in your shoes by anonymousdaredevils, Not Rated, “Foggy, listen to me. This isn't going to make any sense at all, but just – just listen. I need you to come by my place and – walk with me over to Murdock's, because I... need him to tell me how to call in sick.”
  • I Blame the Adrenaline by patster223, Explicit, Brett/Matt, It’s not like Brett Mahoney means to become friends-with-benefits with the Devil of Hell’s Kitchen. It just sort of happens. Or: five times Brett accidentally kissed Daredevil (+1 time he kissed Matt Murdock).
  • Last to Know by whitchry9, Brett keeps getting wildly differing descriptions of Daredevil, and even his own mother seems concerned about the man's welfare. He's starting to suspect they all know something he doesn't. (Secret Identity Reveal)
  • Missing Pieces by whitchry9, Brett has always been good at solving puzzles, so when Matt Murdock is still missing weeks after the events at Midland Circle, he starts investigating. It turns out none of Murdock's friends are too concerned, and their behaviour is even outright suspicious. Brett starts putting the pieces together. The more he collects the more he thinks there's something really wrong with the picture he's getting. And Matt Murdock is looking more and more like a murder victim.
