Clone assassin Clone assassins were a specialized class of clone troopers created by the Kaminoan cloners on the planet of Kamino . These troopers were commissioned by Supreme Chancellor Palpatine , through a special order during the Clone Wars . The assassins were trained specifically to eliminate Jedi by utilizing Teräs Käsi , a form of unarmed combat . Through training duels with Padawans of the Jedi Order , the clones developed greatly enhanced speed as well as an aptitude for anticipating strikes and the ability to resist Jedi mind tricks . Assassins were put in use following the activation of Order 66 , a measure trained into all clone troops that commanded them to kill their Jedi superiors . A unit of the clone variant was sent by Palpatine to assist in on the Jedi Temple on the planet of Coruscant , which took place in 19 BBY . There , Darth Vader , the leader of the assault , along with the 501st Legion , cleared the Temple of all Jedi . Vader activated a beacon , inside the Jedi Temple communication center , designed to contact all Jedi across the galaxy and sent a message ordering all Jedi to return to the Temple , where a large garrison of clone troops was waiting to eliminate each one that did so . The squad charged with defending the beacon was killed by Jedi Master Obi - Wan Kenobi , who was attempting to alter the message to ward any surviving Jedi away , when they attacked him and were rebuffed . History . Clone assassins were specially commissioned by Supreme Chancellor Palpatine , actually the Sith Lord Darth Sidious , as an addition to the Grand Army of the Republic through the Galactic Senate . Palpatine justified the need for these troops in the legislation as a way to combat Jedi if they ever decided to rebel against the Senate and the Republic . In 19 BBY , the final year of the Clone Wars , Anakin Skywalker , a Jedi Knight and friend of the Chancellor , swore fealty to Sidious ' Sith teachings and became his Sith apprentice , taking the name Darth Vader . Afterward , the Dark Lord sent a unit of clone assassins to the Jedi Temple on Coruscant , with Vader and the 501st Legion , to . Amidst of the battle inside the Temple , Vader assigned a squad of six assassins to protect the Jedi Temple communication center , where he had activated a beacon that transmitted to all Jedi in the galaxy , informing them that the war was over and that they were to return to the Temple . A large garrison of clone troops was left in the Temple to intercept and eliminate any returning Jedi . After receiving the beacon ' s message and hearing of the attack on the Jedi Temple , Jedi Master Obi - Wan Kenobi and Grand Master Yoda , deeming it an obvious trap , decided to journey to the Temple in an effort to stop the signal ' s broadcast . Kenobi entered the Communication Room and was cornered by the squad of assassins Vader had stationed there , though he successfully rebuffed them all . Equipment . Clone assassins were outfitted in a standardized variation of the Phase II clone trooper armor to protect them in battle . Wearing this full - body armor , they were still able to perform incredibly dexterous moves to avoid attacks with no obstruction to their movements . The armor had two twin vibro - blades attached to the elbows which extended their reach and increased the lethality of their attacks . These blades spun out from a neutral position and could be locked in place to either follow the troopers ' upper arms or their forearms as they swung at their opponents . The assassins wore parted " kamas " , which were kept on by a belt with two storage pouches on each hip . They also carried blaster pistols . Clone assassins used sniper rifles to execute intruders . Applications . Assassins were commissioned and created for the sole purpose of combating Jedi on equal terms . They were trained to use the martial art of Teräs Käsi , a form of unarmed combat that was created specifically for defeating Jedi , in conjunction with twin vibro - blades on their arms . They honed their skills by fighting Padawans , Jedi trainees , and these battles allowed the clones of the late bounty hunter Jango Fett to increase their speed to a level far beyond that of their template . Their dexterity , mental fortitude , and reflexes were also increased greatly by these battles . They could easily dodge or parry most strikes from melee weapons , such as lightsabers , and were also able to withstand Jedi mind tricks without flinching . A squad of clone assassins could easily defeat a Jedi Knight though were not a true match for a Jedi Master . In addition to their unarmed combat , the assassins were also familiar with the use of blaster technology and carried blaster pistols on their persons . They were used to assist in the cleansing of the Jedi Temple and , later , to defend the temple beacon room from Jedi . Behind the scenes . This clone trooper classification first appeared as an enemy character in the video game . There is a bonus level of the game where Yoda is confronted in the Temple by several squads of clone troops and among them is a squad of six assassins , though the canon icity of this encounter is ambiguous . Concept art from the game depicts a clone assassin with dark armor as opposed to the white and blue seen in the game . In the game , it is indicated that the clone assassins were trained by fighting Padawans . " The Clone Wars Campaign Guide " stated that the class of clone trooper was commissioned via special order by Palpatine , implying that it was done in secret , possibly indicating that the duels were conducted without the knowledge of the Jedi , that these duels never took place , or another option . Adding to the confusion , Obi - Wan Kenobi , a Jedi who sat on the High Jedi Council , was familiar with clone assassins prior to his encounter with them in the Temple . Kenobi also specifically stated that they weren ' t " fighting Padawans anymore , " though this could have been in reference to their operations inside the Temple that day . The assassins are voiced by Raphael Sbarge who also voiced Carth Onasi in Knights of the Old Republic , and RC - 1262 Scorch in Republic Commando . In the second Jedi Temple level of Obi - Wan ' s storyline in the GBA / DS versions of the game adaptation . Obi - Wan ends up fighting a clone trooper that had similar colors to the Clone Assassin , although his method of attacking was closer to the Heavy Weapons Specialist , which was using a launcher to fire several grenades into the air to trap Obi - Wan .
