" Rys " was the nickname assumed by a diplomatic service clone trooper of the Grand Army of the Galactic Republic during the Clone Wars , a conflict against the Confederacy of Independent Systems and their Droid Army . Like all clone trooper s , he was created as a clone of the bounty hunter Jango Fett and trained on the planet Kamino before being deployed . Rys was assigned to be a clone shock trooper in the Coruscant Guard , a division of clones stationed on the planet Coruscant , capital of the Republic . In the year 22 BBY , Rys was picked from the Guard along with fellow clones Jek and Lieutenant Thire to accompany Jedi Grand Master Yoda on a mission to Rugosa , a moon close to the planet Toydaria . Yoda was scheduled to meet secretly on the moon with King Katuunko , leader of the Toydarian people and the Toydaria system , where the Republic hoped to build a supply base . The four were transported to the moon in a Republic cruiser ; however , upon reaching Rugosa , the cruiser found its communications jammed and then came under attack from two Separatist frigates . As the cruiser was taking heavy fire , Yoda ordered that he and the clone troopers be launched to the moon ' s surface in an escape pod so that the ship could retreat . Upon reaching the moon ' s surface , Thire , the highest - ranking clone present , made contact via hologram with Katuunko for Yoda and discovered that Separatist agent Asajj Ventress had already reached the king with an offer of allegiance from Count Dooku , leader of the Confederacy . A deal was struck between the three parties where if Yoda and the clone troopers could evade capture by Ventress ' s forces and reach Katuunko , Toydaria would join the Republic — otherwise , the Separatists would have their allegiance . Once the discussion was over , Rys spotted a landing craft delivering the Separatist troops they were to face , and Yoda gave orders for the clones to only carry what they needed to avoid being slowed down . He then led them on an indirect route toward the meeting place , hoping to avoid encountering the battle droid s located between them and their objective . Journey to meet Katuunko . As they traveled , Rys and his comrades were spotted by the Separatist forces , who began firing with Armored Assault Tank s . As the clone troopers were out of range , Yoda ordered them to wait , and soon the tanks were forced to stop , as they could not move through the coral growths that covered Rugosa ' s surface . The droid s ' commander , 224 , then ordered his ground troop s to advance on foot . The clones moved to flank the incoming droids from the south , hiding behind corals until the Separatists approached and then opening fire . Rys and Jek managed to destroy a squad of B1 battle droid s together before reuniting with Thire and learning that he had lost Yoda . The trio were then forced to retreat by a group of B2 super battle droid s , Thire was knocked to the ground by heavy weapons super battle droid ' s missile as they fled . While Rys ran back to aid the lieutenant under covering fire from Jek , Yoda arrived and defeated the droids using the Force . The respite from combat was short - lived , as three droideka s quickly replaced their fallen droid comrades in attacking Rys and his allies , forcing the four to retreat . With Thire injured , Yoda ' s team settled to rest in a cave and took stock of their low amount of ammunition . After Rys declared the battle lost , Yoda provided reassuring words to the clones , telling Rys to pay more attention to and gain inspiration from his teammates instead of focusing on the enemy . The four then heard the sounds of Separatist tanks outside and moved to the top of the canyon the cave was located in to view the enemy . Yoda leaped down and took on the droids and tanks alone , quickly destroying all of them . Rys and his comrades then spotted more droidekas headed toward the Jedi , and as the droids opened fire on Yoda , Jek fired the clones ' last rocket into a rocky overhang that promptly fell and crushed the droids . Victorious , the group made its way to the meeting point and found Ventress trying to kill Katuunko on Dooku ' s orders , as the king had chosen to ally with the Republic . Yoda quickly saved Katuunko , forcing Ventress to escape while she distracted the Republic troops with a remotely triggered rock slide . Yoda prevented the debris from reaching them by using the Force , after which Katuunko offered the service and allegiance of the Toydarian people to the Republic , marking the mission as a success for Rys and his group . A " Venator " - class Star Destroyer then arrived in the skies above Rugosa , and a Low Altitude Assault Transport / infantry was dispatched to pick up Katuunko , Yoda , and the three clone troopers . Personality and traits . As a clone of Jango Fett , Rys stood 1 . 83 meter s tall , with black hair , brown eye s , and tan skin . He had a black tattoo running up his neck and onto the back of his jaw on each side of his face . During missions , Rys tended to focus on the enemy rather than his fellow soldier s , a trait Yoda picked up on during their time together . Rys struggled to understand Yoda ' s odd phrases and wise sayings , but he believed that such difficulty was to be expected from conversations with a Jedi Master . He was quick to declare the Rugosa mission lost while the clone troopers rested in the cave but took heart after hearing Yoda ' s words of encouragement and was consequently not discouraged when he saw the enemy ' s tanks . Equipment . Rys wore Phase I clone trooper armor painted with the red coloring of the Coruscant Guard . On Rugosa , he carried a backpack and a DC - 15A blaster . Behind the scenes . Rys first appeared in " Ambush , " the first episode in the of the " " television series , which aired on October 3 , 2008 . Like all clones in the series , he was voiced by Dee Bradley Baker .
