CC - 4477 CC - 4477 , nicknamed " Thire , " was a clone trooper lieutenant , and was later the commander of the elite shock troopers of the Coruscant Guard for the Galactic Republic during the Clone Wars . Biography . Mission to Rugosa . In 22 BBY , early in the war , Thire , serving as a lieutenant in the Coruscant Guard , was assigned , alongside troopers Jek and Rys , to escort Jedi Master Yoda during a diplomatic mission to Rugosa to meet with the neutral king of Toydaria , Katuunko . When their " Consular " - class frigate was ambushed by two Separatist " Munificent " - class star frigates , Yoda and the three troopers escaped the transport while it fled and made their way to the moon ' s surface in an escape pod . Arriving in the moon ' s thick coral jungle , CC - 4477 patched into the King ' s communication system , allowing Yoda to speak to Katuunko through a holotransmission . The King was pleased to see that the Jedi Master was not frightened away by Count Dooku . Yoda became aware of Asajj Ventress ' presence , as the Dark Acolyte proposed a contest to demonstrate which side was superior . Ventress would dispatch her forces to capture Yoda , and if he defeated them , the Toydarians would join the Republic , however if the droid forces defeated Yoda , the King should consider joining the Confederacy . Agreeing to the challenge , Yoda and the clones made their way into the dense coral forest . In pursuit was a column of Confederate forces led by 224 in his Armored Assault Tanks . However , the droids were forced to continue on foot after the tanks were unable to get through due to the dense foliage . Thire , Rys , and Jek split from Master Yoda to use their surroundings . The clones took cover and engaged a squad of B1 battle droids from the south and defeated them , but B2 super battle droids soon followed , and the three were forced to flee . During their escape Thire was hit by a rocket launched by a B2 - HA series super battle droid . With Thire injured and pinned behind a rock with Rys and Jek , the clones prepared to make a final stand , but Yoda came to their aid using the Force to turn around the B2 battle droid and destroy the rest of its squad . The small victory was short lived as Droidekas soon appeared which caused the Republic forces to flee . Yoda clung onto CC - 4477 ' s back and deflected the lasers at a nearby tall formation of land coral , causing the droids to be crushed , and the four escaped to a cave to rest . Lieutenant Thire and the other clones learned that they were low on ammunition and their morale ran low , but the Jedi Master imparted his wisdom on the clone troopers , telling Thire to have patience , rather than rush headlong into battle . Their quiet contemplation on Yoda ' s words was interrupted by the sound of the droids approaching . Venturing out of the cave the four looked down on the droid column . Yoda ordered the clones to stay on the ridge and said that he would go in alone , stating that they will know when to help him . Thire and his men looked on as Yoda single - handedly took out the droid column . However the clones spotted droidekas approaching an unaware Yoda . Just as the last AAT was destroyed , the droidekas fired upon Yoda . While Yoda was deflecting laser blasts , Thire fired the squad ' s remaining rocket into an overhanging cliff , causing an avalanche to crash down on the droideka reinforcements , saving Yoda . With Ventress ' forces defeated the group headed back to the rendezvous to meet with Katuunko . Promotion . Following his graduation from the ARC program and a promotion to Commander , Thire was placed in charge of the Coruscant Guard . Together with Republic Intelligence Director Armand Isard , the two founded Homeworld Security Command in an effort to centralize and streamline the defense of Coruscant should an attack ever come . A part of Thire , however , always felt as though the Republic would never be able to muster a reliable defense of Coruscant . Battle of Coruscant . Thire ' s worst fears were realized when General Grievous launched a surprise attack on the capital in the early hours of the morning . Thire ' s men , in conjunction with Commander Appo ' s 501st Legion , did their best to keep the Confederacy ' s droid forces from taking the Senate District . While they were able to halt the Separatist advance , they were powerless to stop the abduction of the Chancellor by Grievous and his MagnaGuards . Order 66 . The execution of Order 66 and the 501st Legion ' s on the Jedi Temple brought about the end of the Clone Wars and the Declaration of a New Order . After an epic battle in the Senate Rotunda between Emperor Palpatine and Jedi Master Yoda , the Emperor tasked Commander Thire and his men to scour the bowels of the Senate , looking for any sign of the diminutive Jedi , ironically forcing Thire to hunt down the very Jedi Master who saved his life on the Coral moon . Although Thire ' s increased efforts to find Yoda had failed , the Emperor was far more concerned with the status of his newest apprentice , whom he sensed was in grave danger . Thus , Thire and his shock troopers accompanied Palpatine to Mustafar , where they brought the medical capsule to the gravely injured Anakin Skywalker , now Darth Vader . Imperial service . Thire served as one of Palpatine ' s personal guards on Coruscant and during off - world trips . As the Empire ' s noose around the galaxy tightened , Thire saw his shock troopers transformed into the foundation of the Imperial era Coruscant Guard , which was tasked with the security of the Imperial capital . Behind the scenes . Thire was voiced by Temuera Morrison in " " . In the " " episode " Ambush " he was voiced by Dee Bradley Baker along with all other clones in the series . Some of Hasbro ' s 2009 incorrectly stated that CC - 4477 ' s mission to Rugosa took place in the Toydarian system and on Toydaria itself .
