Colt / Legends " Colt " was the nickname of an Advanced Recon Commando who served in the Grand Army of the Republic during the Clone Wars . Commander of the Rancor Battalion and an advocate of unity on the battlefield , Colt was assigned to Tipoca City on Kamino to select potential ARC trooper candidates from squads of clone cadets nearing the end of their training . Colt was still on Kamino when the Confederacy of Independent Systems launched an attack on the cloning facilities there . The ARC trooper participated in the defense of Tipoca City but was killed by the Confederate Dark Jedi Asajj Ventress . Biography . One of many soldiers cloned from the Mandalorian bounty hunter Jango Fett on the planet Kamino and trained to serve the Galactic Republic , Colt was an Advanced Recon Commando commander tasked with leading Rancor Battalion of the Grand Army of the Republic during the Clone Wars . He was also given the task of overseeing the selection and training of new ARC trooper recruits . Around 22 BBY , Colt was reassigned to Kamino to oversee the final stages of training for clone cadets in Tipoca City , and the members of the cadet squad who performed the best in the last challenge were to be selected as ARC troop candidates . Introduced to the cadet squads by the Siniteen instructor Bric , Colt addressed the men , stressing the importance of unity on the battlefield . He selected Bravo Squad to first perform the final challenge , as the squad ' s cadets had completed their trial run in record time — " ARC trooper time , " as Colt saw it . From an observation platform overlooking the practice chamber , the commander instructed the Arcona trainer El - Les to initiate version THX , variable 1138 , of the Citadel Challenge . Bravo Squad ' s performance in the test greatly impressed Colt , who congratulated the instructors on their training of the cadets . Domino Squad was the next to run the simulation , but Colt felt their handling of the test was " sloppy " and " unorthodox , " and he soon ended the challenge when the cadets left one of their own behind . The ARC trooper additionally berated the squad for disobeying directives and breaking formation . Left with no choice , El - Les failed Domino Squad , though the cadets later succeeded when given a second opportunity to pass the simulation . Colt remained on Kamino as the war progressed and was in Tipoca City when the Confederacy of Independent Systems launched an attack on the planet . The commander assisted with the defense of the city , leading ARC troopers during the battle and engaging Separatist B1 battle droids within one of the city ' s halls . Outnumbered , Colt was preoccupied with fending off the remaining droids when the Confederate Dark Jedi Asajj Ventress sneaked up behind him . Ventress grabbed Colt in a Force grip , telekinetically lifting the helpless ARC commander off the floor before slamming him into the opposite wall , knocking off his helmet on impact . Still holding Colt within her Force grip , Ventress telekinetically pulled the commander into the blade of her lightsaber , impaling and killing him . She then kissed him as she disengaged her lightsaber , letting his body crumple to the floor . Personality and traits . An expert in ground and aquatic warfare , Colt believed strongly in the unity of and brotherhood between his fellow clone troopers — especially when in battle — and stressed this lesson to the clone cadets whose training he was assigned to supervise . Bravo Squad ' s performance , specifically , greatly impressed the commander — the cadets had completed their trial run in record " ARC trooper " time and had performed their final test flawlessly . His evaluation of Domino Squad , conversely , was quite different — the cadets ' shoddy handling of the Citadel Challenge had revealed their disunity and noncompliance , and Colt wasted no time in berating them for their mistakes . When faced with a Separatist attack on Tipoca City , Colt and other clones fought against invading battle droids despite overwhelming odds . The commander continued to fight even after his comrades were killed , until he himself was struck down in battle . The pattern on his helmet identified Colt as a member of the Rancor Battalion . Behind the scenes . Commander Colt first appeared in " Clone Cadets , " the first episode of the of " " , having previously been shown in promotional material for the season . He later appeared in the second episode , " ARC Troopers . " Although he was not identified by name in either " ARC Troopers " or the accompanying episode guide , the ARC trooper killed by Ventress in the episode wears armor identical to that of Colt , and this article therefore assumes that both characters are one and the same . A portion of Colt ' s death in " ARC Troopers " was removed from the aired episode . In the original scene , Ventress gave Colt a after impaling him but before deactivating her lightsaber . This modification was done at the insistence of Cartoon Network at Celebration V . However , the full scene was still present in the Dataclip summary of the episode on Cartoon Network ' s website , as well as on the third season ' s .
