The Quintet is a group of hitmen working for the Pizza Bat corporation, and were hired to kill Bishop Shidux the same night that Travis re-entered the rankings of the UAA. Appearing as generic mobster scum, their faces are scarred and they dress in black attire. The ringleader, dressed in biker gear, may be an homage to Jack from MadWorld.
All five hitmen are available to fight in the second of every two Revenge Missions, where they are all have health slightly higher than a usual enemy. The mission can be completed instantly if Travis bypasses the cronies in the area and kills the target.
