Born on the planet Kamino and bred from the genes of the human male bounty hunter Jango Fett , the clone trooper commander that would eventually receive the nickname of " Doom " was specifically cloned to fight and die for the Galactic Republic as a part of a massive clone army . The army was first pressed into service when Republic Jedi engaged the droid forces of the Confederacy of Independent Systems on the planet Geonosis , which sparked the start of the intergalactic Clone Wars . Doom was eventually placed under the command of the Jedi Generals Tiplar and her sister Tiplee , and the troopers placed under his command adopted a green color motif for their armor , along with a yellow triangle to represent their company . Battle of Ringo Vinda . During the war , Doom , Tiplar , and Tiplee participated in a large - scale campaign which centered around the capture of a massive space station that encircled the planet Ringo Vinda , which was currently under the command of Admiral Trench and his droid forces . Doom ' s company was joined by the 501st Legion , led by Jedi General Anakin Skywalker , for the battle , which at some point reached a stalemate . During the intense fighting that took place aboard the station , much of Doom ' s company was obliterated , but after several more encounters with Trench ' s droids , the Republic troops captured a communications center . Skywalker began to pen the next stage of the battle , and ordered Tiplar and Doom to take the remainder of their company down one of two passageways that led to Trench ' s command post . Doom noted that his men were few , which prompted Skywalker to assign ARC trooper CT - 5555 , nicknamed " Fives , " and clone trooper CT - 5385 , nicknamed " Tup , " along with ten other 501st troopers , to accompany Doom and Tiplar . Tiplee would follow Skywalker and the rest of his troopers down another passageway . The Republic resumed their assault and began closing in on Trench ' s command center . Tiplar and Doom fought side - by - side as they advanced , and faced minimal casualties during their trip down the passageway . Eventually , they reached Trench ' s command center and regrouped with Skywalker and Tiplee . However , as the fighting commenced , Tup , having entered a trance - like state , unexpectedly shot Tiplar in the back of the head . Doom witnessed the murder , but was forced to continue fighting with the arrival of destroyer droids . Meanwhile , Tup was apprehended by Fives while Tiplar ' s body was retrieved by Tiplee . The entire attack lost its momentum in the wake of Tiplar ' s death and Skywalker ordered a retreat . The defeated Republic forces regrouped in the command center they had previously captured , and Doom and his men gathered around Tiplar ' s body to mourn her death . Tup had killed Tiplar due to a Sith - implanted control chip in his head , a device which was actually installed into every clone trooper ' s head . Tup ' s chip had malfunctioned , prematurely invoking Clone Protocol 66 , which was a command that forced clone troopers to execute all Jedi for acts of treason . Personality and traits .

Doom worked well with Master Tiplar , covering each other during the fighting . He , along with the other troopers of his company , mourned Tiplar ' s death , and expressed confusion at Tup ' s seemingly inexplicable murder .
