In 32 BBY , he led an army of Gungans to pin down Trade Federation forces during the Battle of Naboo . During the Clone Wars , he was promoted to a general in the Gungan Grand Army , served during the Battle of Mon Cala , and ultimately gave his life to defend Naboo against Separatist forces led by General Grievous . Biography . Tarpals ' s family had a long history of military service , with each son serving in the Gungan Grand Army . Roos Tarpals was the first of his family to merit the rank of captain . He was elevated to hero status in the eyes of his clan for this achievement . Before his enlistment in the army , Tarpals was originally the leader of a small band of thieves . It was here that he first encountered Jar Jar Binks . Tarpals used Jar Jar as a distraction for guards and security while he pulled off various heists . The two Gungans became friends . However , it was the captain ' s duty to enforce Jar Jar ' s banishment after he was exiled for destroying Boss Rugor Nass ' s prized heyblibber . The arrest of his friend didn ' t go smoothly , as Binks had angered former General Brass Marshoo . Marshoo knocked Tarpals unconscious to get at Jar Jar , who managed to fend him off . He woke Tarpals , who tied up Marshoo and proceeded with the task of arresting and exiling Binks . He never saw Jar Jar Binks again until 32 BBY , during the Naboo Crisis , when the latter broke his sentence of exile by returning to Otoh Gunga . He halted Jar Jar , and then reprimanded his former friend by pointing out that he made a " big doo - doo " this time by not only illegally returning to Otoh Gunga , but also bringing outsiders ( Jedi Knights Obi - Wan Kenobi and Qui - Gon Jinn ) into the city , and likewise had all three arrested and brought before Boss Nass . In a strange turn of events , Tarpals served under General Binks in the Battle of Grassy Plains . In the battle , the captain fought bravely against the droid forces of the Trade Federation , destroying many Battle droids , though he was captured when he attempted to rescue Binks . As the battle droids surrounded Tarpals and Binks , Anakin Skywalker destroyed the Droid Control Ship . The droids were deactivated and Tarpals and Binks were saved . Clone Wars . During the Clone Wars , Tarpals had been promoted to General , and was present when Jedi Master Yoda requested help from the Gungan Grand Army to aid in the situation on Dac during an engagement with the Separatists there . After helping the citizens of Dac , Tarpals was present in the High Tower Boardroom where Boss Lyonie ordered his people to turn against the Naboo and serve the Confederacy of Independent Systems . In reality , Lyonie was under the influence of a necklace that had been bewitched by his advisor , Rish Loo , a practitioner of dark Gungan magic and secret ally of Count Dooku . Rish Loo ' s treachery was ultimately exposed when Anakin Skywalker and Senator Amidala , former queen of Naboo , came to Otoh Gunga to negotiate with Lyonie . Rish Loo managed to escape but not before severely injuring Lyonie and leaving him incapacitated . Due to his strong physical resemblance to Lyonie , Jar Jar Binks posed as the Gungan leader in order to bring an end to the uprising against the Naboo . However , Separatist forces had already begun to land on the planet ' s surface and awaited Gungan support . Tarpals accompanied Jar Jar , who continued to pose as Lyonie , to his meeting with the leader of the Separatist invasion force : General Grievous . Knowing Grievous ' high standing in the war , Jar Jar signaled Tarpals to contact Amidala immediately . Together , Tarpals and the former Senator hatched a plan to deactivate the Separatist battle droids and capture Grievous alive . While Jar Jar stalled Grievous , Tarpals and his militiagungs successfully shut down the battle droids and prepared to ambush the Separatist general . Grievous , however , caught wind of the Gungans ' plan and confronted Tarpals and his troops . Tarpals fought head - to - head against the cyborg general , but Grievous proved too fast for the aged Gungan and mortally wounded him . In one last heroic act , Tarpals impaled Grievous ' armor with his spear . Jar Jar and the militiagungs quickly subdued Grievous with a barrage of boomas and successfully captured him , thanks to Tarpals ' heroic sacrifice . His friends then turned to aid him , but he had passed while they had dealt with the cyborg general . Amidala , Jar Jar , and his fellow Gungans mourned the loss of their friend . Even though he died to capture the General , his sacrifice was tarnished when the Republic had to make a prisoner swap with the Separatists : Anakin for Grievous . He was avenged by Obi Wan Kenobi when he finally killed Grievous on Utapau . Personality and traits . Tarpals had great sense of duty and honor and was willing to give his life for his people .
