Gungan Grand Army The Gungan Grand Army was a massive army on the planet Naboo composed entirely of Gungan s . Its efforts were key to victory in the conflict when the Trade Federation launched an invasion of Naboo and enslaved the Naboo people . Later , the army assisted in the Battle of Mon Cala at the request of Jedi Grand Master Yoda . History . Invasion of Naboo . Ten years before the outbreak of the Clone Wars between the Galactic Republic and the Confederacy of Independent Systems , the Trade Federation placed a blockade around the planet Naboo and then invaded and occupied the surface . During the battle to free the planet from the Federation ' s grasp , the Gungan Grand Army was summoned by Boss Nass at the request of Queen Amidala of the Naboo . Under the command of Roos Tarpals and Bombad General Jar Jar Binks , the Gungan Grand Army battled the Trade Federation Droid Army on the Great Grass Plains 40 kilometers outside the planetary capital of Theed , effectively acting as a distraction to lure the battle droid s away from the city in order to allow Amidala and the Royal Naboo Security Forces to infiltrate the Theed Royal Palace and capture Viceroy Nute Gunray . The Gungans were initially defeated , but the battle droids were shut down after Anakin Skywalker destroyed the orbiting Droid Control Ship . Clone Wars . During the Clone Wars , Jedi Grand Master Yoda contacted the Gungan Boss Lyonie of Otoh Gunga to request aid in the Battle of Mon Cala . Binks , now a Senator in the Galactic Senate , convinced Lyonie to assist the Grand Army of the Republic . A portion of the Grand Army was sent to Mon Cala onboard a " Venator " - class Star Destroyer . Many Gungans died in the battle against the aqua droid s , and many more were captured when the Separatist leader Riff Tamson used a " Trident " - class assault ship to create a whirlpool . The prisoners were sent to a prison camp among Mon Cala ' s coral reefs . Soon after , the Mon Calamari prince Lee - Char visited the camp and told the prisoners to wait for his signal before attacking . Lee - Char was captured , brought before Tamson , and scheduled to be executed . The members of the Grand Army were freed by the Quarren , who had originally allied with the Separatists but betrayed them . The Grand Army was able to fight back , and some Gungans joined Captain Ackbar in taking down a Trident assault ship . In the end , the battle was won by Republic and Gungan forces , and Lee - Char was crowned king . Later in the Clone Wars , unrest began to occur on Naboo due to circulating rumors stating that the Gungans had allied with the Separatist Alliance . Boss Lyonie called on the Grand Army to march on Theed . Amidala , now Naboo ' s senator , and Skywalker returned to Naboo to defuse the situation . They met Binks on Lake Paonga , and the Gungan took them to Otoh Gunga to meet Lyonie . Lyonie rejected their help , but Skywalker noticed Lyonie was under a form of mind control from a necklace given to him by Minister Rish Loo . The Jedi crushed the necklace and freed Lyonie . Loo then stabbed Lyonie as the Boss confronted him . Loo escaped Otoh Gunga and went to the surface to inform the Grand Army that Lyonie was dead and rally them to march on Theed . Though Lyonie survived being stabbed , he remained unconscious . Skywalker , noticing that Binks resembled Lyonie , convinced him to pose as the Boss in order to convince the Grand Army to call off the attack . Binks was able to fool the Grand Army into believing that he was Lyonie , and Rish Loo , seeing that his plans had been foiled , escaped deeper into the swamps on a Flitknot speeder . Three C - 9979 landing craft landed in the vicinity , and one deployed a tactical droid with a B2 super battle droid escort . Binks and General Tarpals followed the tactical droid onto the landing craft , where they met General Grievous . Binks , still posing as Lyonie , told the general that he wasn ' t going to attack Theed . That angered Grievous , and Binks caved and ordered Tarpals to prepare the troops for battle . Tarpals went on to contact Amidala , who suggested a strategy . Meanwhile , Grievous was able to see through Binks ' ruse and attempted to kill him . Binks managed to escape and realized that the Grand Army had succeeded in shutting down the droid army and had gathered around Grievous . Tarpals and several other warriors fought the general . Tarpals was fatally stabbed by Grievous , but managed to impale the cyborg with a spear . The distraction gave the other Gungans enough time to attack Grievous with booma s and capture him . Skywalker pursued Loo to his secret outpost , which was being used by Count Dooku , the head of the Confederacy of Independent Systems . Dooku killed Loo , and then subdued and captured Skywalker . Amidala agreed to free Grievous in exchange for Skywalker , and the Grand Army delivered the general to Dooku . The Separatist army then left Naboo . Neeyutnee , Naboo ' s current Queen , praised Binks for reuniting the Naboo and the Gungans again . Equipment and vehicles . Unlike the Royal Naboo Security Forces at the human city of Theed , the Gungan Grand Army utilized organic beings and limited technology in battle , and was oriented towards a more defensive strategy . The army was composed of roughly 1 , 000 battle - ready animals including fambaa s , falumpaset s and kaadu s . Faambaas often carried deflector shield generator s which could enclose large contingents of Gungan troops , falumpassets pulled large battle wagons while the kaadu served as cavalry mounts for leaders such as Captain Roos Tarpals , who decorated his kaadu with large feathers won as race trophies . Gungan soldiers were often armed with spears or one armed throwing devices known as atlatl , which could throw grenade - like energy weapons known as booma s . Manufactured by the Otoh Gunga Defense League with exotic plasma naturally found in the porous crust of Naboo , boomas could also be thrown with the spear - like cesta or falumpasset - towed catapults . Protecting Gungan forces were the widely distributed Gungan personal energy shield , which utilized hydrostatic bubble technology to protect against blaster fire and physical weapons .
