Brennen Tyler Brennen (Jay Karnes) was a ruthless gunrunner and former military intelligence operative. He is the first villain-of-the-week to become a recurring character and the first person whom Michael can never smooth-talk into doing anything. In the season two episode "Sins of Omission", he kidnaps the young son of the professional thief (and Michael's former fiancée) Samantha Kees (Dina Meyer) to force her to steal the MacGuffin-of-the-week, which he expects will yield enough money to retire. Michael, dispensing with the use of cover identities and approaching Brennen as himself, frees Samantha's son and tricks Brennen into letting him return the item to its rightful owner, forcing Brennen to go on the run from his buyers. In the third-season episode "End Run", he returns, having dispatched his pursuers by a particularly clever ruse. He poses as an investor in the latest business venture of Michael's younger brother Nate. Brennen tells Michael he will have Nate killed if Michael does not agree to help him. Although Michael gains access to the device, he bluffs Brennen into believing that he has drained Brennen's offshore accounts and sent a hitman to kill his daughter. Brennen releases Nate and leaves empty-handed, swearing vengeance. In the fourth season, Brennen returns. In the episode "Dead or Alive", Brennen has Marv (Jesse's former handler) killed and the flash drive that Michael and Jesse had stolen then smiles playfully at Michael from the fleeing vehicle. In the following episode "Out of the Fire", Brennen blackmails Michael into assassinating members of Management and framing a terrorist group. He also hires "Dead" Larry to assist. When Michael and Larry return from the first job at a rendezvous point, Brennen was pouring glasses of champagne in celebration of the victory but Larry double-crosses Brennen and kills him. Brennen is the second longest recurring villain (outside main antagonist) next to Larry. Michelle Paxson Miami Police Detective Michelle Paxson (Moon Bloodgood) appeared at the start of the third season almost immediately after Michael opted out of protection from "Management". Paxson had noticed shady activity from Michael, Fiona and Sam, and worked to shut down their operation. in "End Run", Michael arranges for evidence to show himself connected to a Mayors Aide to come to light. Paxsons partner Detective Lopez spends three hours interrogating the aide because of this, resulting in the Mayor personally having Lopez suspended. Despite having absolutely no proof that Michael
