Dred Priest was a male Human Mandalorian warrior. He was invited by Jango Fett to participate in the [Cuy'val Dar], training clone commandos on the planet of Kamino. While serving on Kamino, Priest managed to antagonize some of his fellow Mandalorian Cuy'val Dar. Kal Skirata and Walon Vau deeply disliked his Death Watch ideologies, as they strongly felt that Mandalorians should reclaim their past old glory through galactic conquest of the galaxy. Another Mandalorian training sergeant, Mij Gilamar, despised Priest for establishing a Battle Circle, where his clone trainees engaged in fatal combat. Gilamar, who was also a doctor, was forced to treat Priest's wounded trainees, many of whom were beyond saving and eventually died.
Sometime after the rise of the Galactic Empire, Priest, along with his girlfriend Isabet Reau, became involved in the revived Death Watch. Stationed on Mandalore, they actively collaborated with the Imperial garrison. When Gilamar and Kal's adopted son Ordo Skirata encountered Priest in the city of Keldabe, Priest attempted to recruit Gilamar into the Death Watch. After confirming Priest's continued desire to have the Mandalorians rebuild their former empire, Gilamar stabbed Priest above his thigh with a knife, severing his femoral artery and causing significant blood loss. Priest quickly succumbed to his injuries, and his body was disposed of by Gilamar and Ordo, who threw it into the Kelita River.
Dred Priest was a male Human Mandalorian who was one of the hundred training sergeants, known as the Cuy'val Dar. He was selected by bounty hunter Jango Fett to assist in the training of clone commandos on the planet of Kamino. Priest accepted the offer and looked forward to the challenge of creating elite soldiers. While on Kamino, he secretly established a Battle Circle with Isabet Reau—a female Cuy'val Dar with whom he soon began a romantic relationship—where they forced their trainees to engage in brutal competitions. Due to the injuries sustained by the clone trainees, Mij Gilamar—another Cuy'val Dar and the doctor who treated the injured clones—informed Fett about the situation, leading to a violent end to Priest's fight club. Despite this incident and their Death Watch affiliations, Fett allowed them to remain, prioritizing their training results.
The Ba'jurne Kyr'tsad Mando'ad, a manifesto of the Death Watch Mandalorian splinter group, was purportedly written by the movement's leader, Tor Vizsla—although Jango Fett, a rival of the Death Watch, questioned its authenticity in one of his notes, suggesting that Dred Priest or Isabet Reau were the actual authors—and was eventually included in the book The Bounty Hunter Code by Jango's son, the bounty hunter Boba Fett.
In 18 BBY, a year following the conclusion of the Clone Wars and the establishment of the Galactic Empire, Priest and Reau were stationed on the planet Mandalore, collaborating with the local Imperial garrison and recruiting for the newly formed Death Watch. Priest encountered Gilamar and Null-ARC Ordo Skirata, attempting to persuade them to join the Death Watch. They led him into an underground chasm for further discussion. Upon realizing that Priest's beliefs remained unchanged and he was still determined to establish a Mandalorian empire with the Death Watch, Gilamar stabbed him in the leg with his knife, severing his femoral artery and causing Priest's swift death due to severe blood loss. Gilamar and Skirata disposed of his body in the turbulent Kelita River to both delay Reau from discovering his fate and to conceal the identity of his killer.
Dred Priest was a strong advocate for Mandalorian dominance over the galaxy, similar to their ancestors. Mij Gilamar characterized Priest as a ruthless butcher who forced his trainees to fight each other in the battle circle for his own amusement.
Kal Skirata described Priest as having a thin face with a crooked mouth, the kind of face one could punch all day.

This action figure incorporates parts from the 2004 Vintage Original Trilogy Collection Boba Fett's arms and legs, along with a newly designed head, belt, and torso.
Similar to the Rav Bralor figure in the set, Dred Priest seems to be inspired by artwork created by Tom Hodges for the Star Wars Insider 86 article titled The Mandalorians: People and Culture. In this picture, the waist and shoulder ammo belts, cod piece, and upper torso armor are identical. However, the helmet on the action figure lacks the intricate paintwork of the artwork, and the figure does not feature any thigh and shin armor. The legs are sourced from a Boba Fett action figure.
The head beneath the helmet is loosely based on Hasbro employee Derryl Depriest, whose name also served as inspiration for the figure's name.
