Poggle the Lesser was the leader of the insect-like Geonosians throughout the era of the Clone Wars. Due to his control of the Geonosian battle droid factories, he was a powerful figure within the Confederacy of Independent Systems and commanded the droid armies that fought against the Republic in two battles for control of Geonosis. At the end of the war, Poggle lost his life to Darth Vader.
The secret leader of the Geonosians, Karina dwelled in the catacombs beneath the Progate Temple, laying eggs, controlling an army of Geonosian drones, and giving orders to public Geonosian leaders such as Poggle the Lesser. When Poggle fled to the Temple, the Jedi followed and discovered Karina, who had captured Luminara Unduli—and now sought control of Jedi Knights.
At the time of their introduction, the Republic clone troopers represented the future of galactic warfare. Far superior to battle droids, the clone troopers formed the backbone of the Republic's new military that waged war against the forces of the Confederacy of Independent Systems. So symbolic were they of the times, the galaxy-wide conflict that saw their debut took its name from their ranks: the Clone Wars.
Rather than use flesh-and-blood warriors, the Separatists prefer mindlessly loyal soldiers that are easily controlled. The soulless ranks of their armies are dominated by tall, thin B1 battle droids built as mechanical imitations of their Geonosian designers. Battle droids can be controlled by centralized command centers such as the Trade Federation’s enormous Droid Control Ships, or programmed for independent action. They often suffer programming glitches that manifest as personality quirks. Battle droids are dim-witted and no match for clone troopers or Jedi, but they weren’t designed to be smart – they were designed to overwhelm Republic civilians through sheer numbers, something they do very effectively.
Count Dooku was a menacing Sith Lord and central figure in the Clone Wars. Once a Jedi -- trained by Yoda -- he became disillusioned with the Jedi Order and thirsted for greater power. Dooku voluntarily left the light side behind and became Darth Sidious’ dark side disciple, taking the secret name Darth Tyranus and leading the Separatist army. Dooku advanced Sidious’s secret plot to take over the galaxy, but forgot that betrayal is the nature of the Sith.
The Confederacy of Independent Systems, also known as the Separatist Alliance, was a collection of star systems and corporate titans that left the Republic and fought for independence against the Republic’s clone armies and Jedi Knights. The charismatic former Jedi Count Dooku was the Alliance’s political leader, while its military power came from credits and assets donated by powerful galactic trade groups. No one suspected that the Alliance was actually a tool of Darth Sidious, who had engineered the Clone Wars as part of a Sith plot to rule the galaxy.
