Montross was a Mandalorian–turned–bounty hunter who competed with Jango Fett to become the template for the clone troopers of the Galactic Republic. Originally one of Jaster Mereel's True Mandalorians, he became a bounty hunter. Known for his ruthlessness, he almost never took a live bounty. In 32 BBY, he and Fett, now also a bounty hunter, were selected by the ex-Jedi Count Dooku to participate in a hunt to capture or kill the leader of the Bando Gora cult, Dooku's former apprentice Komari Vosa.
