Yos Kolina / Legends Yos Kolina was the eighty - second King of Mon Cala , reigning over the Mon Calamari in support of the Galactic Republic during the Clone Wars . A strong and respected leader , he worked with such advisors as Senator Meena Tills and Captain Gial Ackbar of the Mon Calamari Guard to ensure the well - being of his people , in addition to operating with the Mon Calamari Council . Although the Mon Calamari and their Quarren neighbors always clashed over their differences , Kolina was able to keep the peace thanks to his friendship with the Quarren chieftain , Nossor Ri , with the two leaders dispelling tensions through open discussion and mutual respect . They remained united in their support of the Republic and the Jedi Order , and Kolina even led soldiers from both peoples into battle during his rule over Mon Cala . In the second year of the war , Kolina found the unity of his kingdom challenged when the Confederacy of Independent Systems began to make advances on the Calamari system . Kolina petitioned the Republic and the Jedi High Council for aid , but he was shortly thereafter assassinated by Separatist Commander Riff Tamson . Having been integral to his people ' s peace with the Quarren , Kolina ' s sudden death left the throne to his young son , Prince Lee - Char . Renouncing Mon Calamari rule , Nossor Ri and the Quarren allied with the Confederacy , resulting in civil war on Mon Cala . Nevertheless , Lee - Char was able to bring the fighting to an end with the support of Captain Ackbar and the Republic , succeeding his father as King of Mon Cala . Biography . King of Mon Cala . The Mon Calamari male Yos Kolina was born into the royal bloodline of the planet Mon Cala in the last decades of the Galactic Republic ' s rule . In line for the throne of his homeworld , Kolina ascended to be the King of Mon Cala by the time of the Clone Wars , becoming the eighty - second ruler to bear the title . As the leader of the Mon Calamari , Kolina kept his world allied to the Republic in its war against the Confederacy of Independent Systems , with Senator Meena Tills representing their people in the Galactic Senate . Being the Supreme Commander of Mon Cala ' s military , Kolina was directly served by Captain Gial Ackbar of the Mon Calamari Guard , who acted as the chief military advisor to the crown . Working with a democratically - elected government , the Mon Calamari Council , which balanced out the power of the royal house , Kolina lived in the royal palace in Mon Calamari City , the capital of Mon Cala . He eventually had a son , Lee - Char , who became the prince and was to one day succeed him as the King of Mon Cala . As with his predecessors , Kolina was faced with the challenge of unifying two of Mon Cala ' s species : the peaceful Mon Calamari and the aggressive , isolationist Quarren , who long resented the former ' s advances in technology , the arts , and galactic affairs . Despite their striking differences , Kolina formed a friendship with the chieftain of the Quarren , Nossor Ri , a bond that allowed the two leaders to keep the peace on their homeworld through open discussion and mutual respect . Working closely with Ri , Kolina became indispensable to the civilian harmony amidst the oceans of Mon Cala . Under his rule the Mon Calamari and the Quarren long remained united in their support of the Republic and the Jedi Order . Kolina even led Mon Calamari and Quarren soldiers into a number of battles , displaying bravery and loyalty to his people . During the Clone Wars , the Mon Calamari contributed to the Republic ' s war effort by providing Republic shipyards with a special metal ore to strengthen cruiser armor plating . In 21 BBY , the second year of the war , the Confederacy , looking to bring the Calamari system onto their side , began to make advances on the system with an invasion fleet under the command of General Grievous . Kolina was soon contacted by Jedi Generals Plo Koon and Anakin Skywalker , who sought to learn more about the situation . Kolina reported the imposing threat of the Separatists and stated that without the Republic ' s help , he would be unable to guarantee the stability of Mon Cala or their region of the galaxy , before ending the holotransmission to the Jedi Temple . In response to Kolina ' s statements , Koon brought a clone trooper task force of the Grand Army of the Republic ' s 104th Battalion to the Calamari system , reinforcing a Republic outpost on the comet Iceberg III against Grievous ' s invasion fleet . However , Koon and his troops were unable to prevent Grievous from continuing to advance on the system . Kolina thus faced the rising potential of civil war on his world , with the Quarren — many of whom had grown dissatisfied with the Mon Calamari monarchy as well as the Republic — looking to ally themselves with the Confederacy , in a bid to seize Mon Cala for themselves . The Confederacy capitalized on this rift by targeting Kolina himself . Death and legacy . As part of the Confederacy ' s plan to secure the Calamari system , Commander Riff Tamson was sent to Mon Cala to assassinate Kolina , as doing so would compromise the unity between the Mon Calamari and the Quarren and escalate the world toward civil war . Tamson confronted Kolina in the palace ' s throne room and killed the King of Mon Cala with a staff , leaving his corpse to be found by his people . In the wake of Kolina ' s death , a dispute erupted with the Quarren over their sovereignty and the line of succession of the monarchy . Seeing an opportunity to break free of rule by the Mon Calamari crown , the Quarren challenged the monarchy , hoping to place one of their own on the throne . With a diplomatic crisis unfolding , Captain Ackbar requested the presence of Republic officials to help mediate the situation . Senator Padmé Amidala and Jedi General Anakin Skywalker were sent to Mon Cala , but Nossor Ri responded by asking for a Separatist envoy , who came in the form of Riff Tamson . At a gathering between the Mon Calamari and the Quarren , Ri refused to support the coronation of the young and inexperienced Prince Lee - Char . Tamson exploited the Quarren – Mon Calamari tensions in Kolina ' s absence , convincing Ri to side with the Separatists so that the Quarren could claim control over Mon Cala . In secret , Tamson had made arrangements with Confederate Head of State Count Dooku to be the true ruler of Mon Cala , instead of Ri and the Quarren . In the ensuing Battle of Mon Cala , Tamson and Ri led a combined assault on Mon Calamari City . The Mon Calamari and their reinforcements from the Republic Grand Army continually lost ground , with all of them eventually being captured by Tamson and put to work in prison camps for Dooku and the Confederacy . Tamson then took Kolina ' s throne for himself , much to the shock of Ri and the Quarren , who began to regret their alliance with the Confederacy . When Lee - Char and his Jedi protector , Padawan Ahsoka Tano , were the only ones who had evaded capture , Dooku sought to finish what he had begun with Kolina ' s assassination : the termination of the royal bloodline through the execution of the prince . Despite grappling with the challenge of living up to Kolina , Lee - Char overcame his doubts and grew to become Mon Cala ' s next ruler , using his father ' s old friendship with Ri to convince the Quarren to re - side with the Mon Calamari and the Republic . Tamson and the Separatist presence on Mon Cala were thus vanquished by the allied forces , and Lee - Char succeeded his father as the eighty - third King of Mon Cala . Personality and traits . A Mon Calamari male , Yos Kolina had blue eyes and orange skin . As the King of Mon Cala , he kept his people , the Mon Calamari , allied to the Republic and the Jedi Order in the midst of galactic conflict . He displayed honesty even when it made him regret doing so , telling Plo Koon and Anakin Skywalker that he would be unable to keep the peace in the Calamari system without their help . A strong and confident leader , Kolina dedicated himself to serving all inhabitants of Mon Cala , including his Quarren neighbors , in spite of their differences . He formed a friendship with Chieftain Nossor Ri , becoming his trusted friend and ally , and worked hard to keep disputes civil and respectful through public dialogue . He became vital to the peace on Mon Cala , and his assassination thus caused cooperation to deteriorate and tensions to escalate . As a military commander , he led Mon Calamari and Quarren soldiers into many battles . He was revered for his bravery , to the point that tales were told of his valor as king . A widely respected ruler , he became an example and role model for his son , Prince Lee - Char , who constantly sought to become a leader like him , particularly when tasked with unifying Mon Cala . By the time of Lee - Char ' s coronation , both Captain Gial Ackbar and Senator Meena Tills believed that Kolina would be proud of his son . As the monarch , Kolina wore traditional robes and the shell crown of his people . Behind the scenes .
