Nemesis

The Death Watch, known as Kyr'tsad in Mando'a, was a Mandalorian terrorist splinter group of warriors that opposed the pacifist government of Mandalore (led by Duchess Satine Kryze) during the Clone Wars. After failed attempts at taking over Mandalore, they became part of Maul's Shadow Collective, which successfully took control of the planet during the war. However, a struggle in maintaining power formed between the two former allies, Mand'alor Pre Vizsla and the Shadow Collective's leader, Maul, ultimately resulting in Vizsla's demise, Maul's rise to power, and the separation of Death Watch into the Mandalore resistance, which was led by Bo-Katan Kryze, and Maul's Mandalorian super commandos. Following the end of the Mandalorian Civil War, the remaining Mandalorian martial traditionalists, who believed in the old warrior ways of Mandalore, were exiled to the moon of Concordia, where most of them were thought by the pacifistic New Mandalorians to have died out. However, the survivors eventually regrouped and began calling themselves the Death Watch. Whereas the Old Mandalorians did not seek vengeance on the New Mandalorians, Death Watch intended to overthrow the pacifist government and restore the traditional warrior ways of their people. They were then led in secret by Concordia's governor, Pre Vizsla of Clan Vizsla, who wielded the Darksaber, and Duchess Satine Kryze's sister, Bo-Katan Kryze. Nemesis got his name for his brutality and fierceness in battle. Wielding weapons of powerful brutality such as a flamethrower, a Z-6 Rotary blaster cannon, and stocking up on grenades, it's not surprising that if you see him, you're doomed. Jedi fear his name, and Mandalorians even tread lightly around him; they don't dare speak about him in fear that they might anger him. They say the trauma of losing his closest friends and family drove him into a murderous wrath and rage, and he uses combat as a means to release any built-up anger, which is why he is so brutal in combat
