The Archduke commanded the droid armies that fought against the Republic during the first and second battles of Geonosis , the latter of which he was captured and brought into Republic custody . Incarcerated for two years on Coruscant , he was later recruited by the Republic Special Weapons Group to assist in the construction of the Ultimate Weapon battlestation the Geonosians designed ; however , later absconded to Confederate space after sabotaging the project . During the final stages of the war , he and the rest of the Separatist Council were relocated to Utapau and later on Mustafar , where he was killed by Darth Vader . Biography . During the Separatist Crisis , Poggle was one of the first and one of the most ardent supporters of its cause . He then hosted a meeting of fellow Separatist conspirators on Geonosis , in which he pledged his people ' s army to the former Jedi , Count Dooku . The Clone Wars . First Battle of Geonosis . Poggle , Dooku , and the rest of their Separatist conspirators then went to the Petranaki arena to watch the executions of Padmé Amidala , Obi - Wan Kenobi , and Anakin Skywalker . However , Jedi Master Mace Windu and a team of 212 Jedi arrived to rescue Kenobi , Skywalker , and Amidala . As the battle droid s overwhelmed the Jedi , they were then rescued by clone trooper s under Master Yoda . Poggle and the rest of the separatist conspirators then went to the underground war room to oversee the battle . As the Republic Army forced their Droid Army to retreat , Poggle ordered his warriors to hide in the catacombs . He then gave Dooku the plans for their Ultimate Weapon , who assured that they would be safe with his Master , Lord Sidious . Dealings with Clovis . Poggle , along with Trade Federation Senator Lott Dod , conspired with Scipio Senator Baron Rush Clovis to rebuild the primary droid foundry on Geonosis . When Clovis arrived on Cato Neimoidia at Dod ' s palace , Poggle and Dod demanded a greater share of the profits the foundry would produce . When Clovis refused to change the terms , Poggle agreed with Dod ' s plan to poison his companion , Senator Padmé Amidala . However , Clovis helped Amidala ' s guard get the cure for her . Poggle and Dod then confronted Clovis about the missing holodisc . Second Battle of Geonosis . Poggle later returned to Geonosis and serve as the Overseer of the Geonosis primary droid foundry . When the Galactic Republic invaded the planet , Poggle led both the droid army and the native Geonosian s against the Republic from the foundry . As the Republic forces approached his foundry , Poggle and his tactical droid , TX - 21 oversaw the construction of Super tank s . They then deployed the ten garrisons of droids against the clone troopers under Jedi General s Anakin Skywalker and Luminara Unduli . He and TX - 21 then sent in the super tanks which were able to push the clones back . Poggle was then informed that 2 Jedi had infiltrated the reactor room . Poggle and TX - 21 then went with a pair of his soldiers and one of his super tanks . There , he ordered his soldiers to take the bombs and kill the Jedi . After the foundry ' s destruction , Poggle took an AAT with several of his droids and soldiers with him to the Progate Temple . Along the way , Poggle dropped crates , leaving a trail for Unduli and Buzz to follow . When Unduli and the trooper entered the temple , Poggle and several un - dead Geonosians killed Buzz and captured Unduli . He then took her into the catacombs of the temple and brought her before his queen , Karina the Great , as a gift . Together , they hoped they could use the Brain worm s to control Unduli . However , Poggle and Karina were then found by Obi - Wan Kenobi and Skywalker . As they blinded the queen , Poggle was captured by Skywalker and Unduli . He was taken aboard the " Venator " - class Star Destroyer " Resolute " . On board the " Resolute " , Poggle was interrogated by Kenobi , Ki - Adi - Mundi , and Unduli , but refused to answer their questions . When the worms were aboard his Padawan ' s supply ship , Skywalker interrogated Poggle alone . At first , Poggle refused but was then punched and force - choked . He then revealed the worms ' weakness to the cold . Poggle was then transported to Coruscant , where he would be imprisoned in a cell at the Republic Center for Military Operations . Imprisonment and Republic service . Poggle would remain in Republic custody for thirteen months . During this time , he would be subjected to routine interrogation by agents of Republic Intelligence . One of the main topics of the interrogations was the supposed deep - space mobile battle station project , the " Ultimate Weapon " designed by the Stalgasin hive , that was thought to be under construction by the Confederacy . However , the Archduke repeatedly denied any Geonosian association , and feigned ignorance to the existence of the plans , which were actually in the possession of the Republic Special Weapons Group . Poggle was later approached by Lieutenant Commander Orson Krennic of the Special Weapons Group , in another attempt to garner information on the Confederacy ' s Ultimate Weapon . Krennic , who himself was attempting to spearhead the project to develop the station , was able to appeal to Poggle ' s loyalty to his people and convinced him to provide the Geonosian drone population as a workforce for the battle - station ' s construction . With this allegiance to the Republic , the Archduke was returned to his homeworld on the eve of Meckgin , in which , amidst bloody celebrations , was able to convince the Geonosians to assist in the Republic ' s construction efforts . However , Poggle had ulterior motives for providing such assistance to the Republic . Allotted with a private retinue of drones , Poggle secretly directed a massive uprising of the Geonosian soldiers servicing the battle - station as a diversion for his own escape to the Confederacy . In addition to sabotaging the construction project , the Archduke , with his own modified personal shuttle , was able to slip through the Republic flotilla in orbit and flee into hyperspace . Death . After escaping from Geonosis , Poggle rejoined the Confederacy as the war began to draw to its close . Following a string of Republic victories , General Grievous ordered the members of the Separatist Council , including Poggle , to remain under his protection . Grievous hid them on Utapau while he prepared a strike on Coruscant ; following Count Dooku ' s death and Grievous ' s failure at Coruscant , Poggle and the other Separatist leaders were sent to a fortified bunker on Mustafar , by order of Darth Sidious . When Anakin Skywalker , now as Sidious ' s new apprentice Darth Vader , arrived on Mustafar , the Separatist leaders discovered that he was sent not to reward the council , but to execute them . Poggle attempted to defend himself using his staff , to no avail , and was quickly cut in half . Behind the scenes . Poggle the Lesser was voiced by Marton Csokas in " " , and by Matthew Wood in . In a deleted scene for " Attack of the Clones " , Poggle sentences Anakin and Padmé to their deaths . In the DVD commentary , it is stated that Poggle was made to look different than other Geonosians so it was obvious he was their leader , similar to how Boss Nass was designed to look different from the other Gungan s .
