A Mandalorian male affiliated with the Death Watch faction took part in the Clone Wars. Acting as a key subordinate to Pre Vizsla, who commanded the Death Watch group stationed near Mandalore's moon, Concordia, he was dispatched to Coruscant following an idea put forth by Count Dooku of the Confederacy of Independent Systems with the mission to assassinate Satine Kryze, the Duchess of Mandalore and head of the New Mandalorian reform movement. Upon arrival, this assassin targeted Satine, initially trying to eliminate her by tampering with her speeder. He later implicated her in the death of an informant, Davu Golec, whom he killed using a BX-series sniper rifle. During a subsequent assassination attempt, the assassin battled Obi-Wan Kenobi, a Jedi Master and friend of Satine, ultimately suffering defeat. In the end, the assassin failed to complete his assigned task.
The character of the Unidentified Death Watch assassin was first seen in the animated series Star Wars: The Clone Wars, specifically in the episode titled "Duchess of Mandalore." Dee Bradley Baker provided the voice for this character in that episode. Baker also voiced all of the clone troopers in the series, and also played Bossk'wassak'Cradossk.
