Death Watch was a brutal organization of Mandalorians that were prominent during the Clone Wars. They worked closely with Darth Maul, and were a part of the Shadow Collective. When Pre Vizsla was killed by Maul, the Dearth Watch were under Maul's command. The Mandalorians of Death Watch wore dark grey and blue armor with yellow, white and red patterns.
They were incredibly brutal and evil, once even burning a whole village to the ground. They would reprogram droids to use as target practice, and capture innocent civilians and force them to cook their food and do other similar tasks. They crumbled in 19 BBY following the defeat of Darth Maul and the Republic victory of the Siege of Mandalore. Many surviving members fled to many different locations in the Outer Rim, and planned to recreate the Death Watch, however, they failed.
