Cydon Prax Cydon Prax was a male Chistori who became a Separatist soldier during the Clone Wars . Following the death of Jango Fett at the Battle of Geonosis in 22 BBY , Prax succeeded the slain Mandalorian bounty hunter as the chief bodyguard of Count Dooku , a Jedi apostate and apprentice to the Sith Lord Darth Sidious . One month after the first battle of the Clone Wars , Cydon Prax discovered the remains of the ancient Force Harvester on the planet Raxus Prime with the aid of Bera Kazan , a smuggler and fellow mercenary employed by Count Dooku . The Harvester , a device created to drain the life force from all living beings within close proximity , was quickly rebuilt by the Separatists in the Kashyyyk system . At the Count ' s behest , Prax activated the Harvester on the forest moon of Alaris Prime as an experiment to test the magnitude of the weapon ' s power . When news of the incident reached the Galactic Republic , the Jedi Order launched a Dark Reaper campaign to destroy the Dark Reaper , a superweapon that incorporated the Harvester in its design as a power source . At the Battle of Thule , Prax guarded the Reaper in the ancient Sith city of Kessiak as the Jedi - led clone army assaulted the Separatists ' position . The Chistori soldier ultimately perished in battle during a firefight with the Jedi Anakin Skywalker . Shortly after Prax ' s death , Skywalker single - handedly destroyed the Dark Reaper and brought an end to the crisis that nearly brought about the defeat of the Republic and their Jedi defenders . Biography . A male Chistori , Cydon Prax achieved distinction in the Clone Wars as an elite soldier of the Confederacy of Independent Systems — the secessionist organization that waged a civil war against the Galactic Republic by the year 22 BBY . With the death of the Mandalorian bounty hunter Jango Fett at the first engagement of the war , the Sith Lord Darth Tyranus — better known in public as Count Dooku — had lost his most trusted right - hand man to the beheading strike of the Jedi Master Mace Windu ' s lightsaber . In the same year that marked Fett ' s demise on Geonosis , Dooku swiftly replaced the late mercenary with Cydon Prax . As Dooku ' s newest bodyguard , Prax was entrusted with the execution of several missions that the Count regarded as important to the Separatist cause . Prax was also charged with taking custody over the young Boba Fett , an unmodified clone of Jango Fett that the latter raised as his son . However , Prax failed to be an effective substitute for the orphan ' s lost father . Cydon Prax accompanied Count Dooku to Raxus Prime where the Separatists excavated the remains of the Force Harvester , a vital component to the reconstruction of the ancient superweapon known as the Dark Reaper . A contingent of the Grand Army of the Republic attacked the planet and although the battle was ultimately a draw , both Dooku and Prax escaped with the Jedi Padawan Anakin Skywalker in pursuit . Skywalker confronted the Count alone in a brief lightsaber duel until Prax rendered him unconscious with the stun setting on his heavy blaster pistol . Once the Force Harvester was fully reconstructed on Alaris Prime , a forest moon that orbited the planet Alaris in the Kashyyyk system , Cydon Prax activated the device on the order of Count Dooku , who wished to see its effects on Force - wielders like Skywalker . Prax then vacated the entire area soon after the Harvester ' s activation , given that it was designed to kill every living being within close proximity . Despite this , Skywalker managed to escape the weapon ' s blast radius with the aid of Bera Kazan , a former Separatist mercenary who aided Prax in locating the Harvester shortly before being betrayed and used as a test subject for the machine . The crisis came to a head at the Battle of Thule , just as Count Dooku and Cydon Prax oversaw the completion of the new Dark Reaper superweapon . In the midst of a firefight between Republic clone troopers and Separatist battle droids , Prax entered the battlefield in his personal Dreadnought battle tank . Although he destroyed Mace Windu ' s TX - 130 Saber - class fighter tank , the Jedi Master survived his vessel ' s destruction and continued to lead the Republic forces on the front line . Meanwhile , Prax regrouped with Dooku in the ancient Sith city of Kessiak , also the capital of Thule where the Dark Reaper was held . When Anakin Skywalker led a division of clone units into the city while piloting his own TX - 130 tank , Count Dooku ordered Cydon Prax to confront and kill the young Jedi shortly before departing the planet . Thus , a firefight began between Prax and Skywalker that culminated with the latter ' s victory and the destruction of Prax ' s Dreadnaught battle tank , ending the Chistori mercenary ' s life . With the destruction of the Dark Reaper , the Republic claimed victory on Thule . Personality and traits . Cydon Prax was known as a callous , dispassionate being and a lethal soldier on the battlefield . His pitiless demeanor affected his ability to raise Boba Fett in Jango Fett ' s place , making him an unsuitable father figure . It also left him desensitized to mass murder as he felt no compunction about utilizing the Force Harvester ' s lethal energies on Alaris Prime , a moon filled with numerous specimens , including Wookiee settlers . His utter lack of ethics also rendered him unconcerned with acts of treachery , such as when he betrayed and imprisoned Bera Kazan shortly after she aided him in the Separatists ' search for the Force Harvester . In addition to his skills as an elite trooper and marksman , Cydon Prax was a talented pilot who could compete in battle with highly - skilled Jedi such as Mace Windu and Anakin Skywalker . Due to his Chistori biology , Prax was a cold - blooded reptilian ; a fact that contributed to his reputation as a mercenary who possessed a " heart of ice . " His other physical features included square teeth and a crown of horns that adorned the base of his skull . Equipment . During the Clone Wars , Cydon Prax wore a fully - encased suit of armor , much like his predecessor Jango Fett , that concealed his alien appearance . Though Prax ' s armor was not of Mandalorian design , its most prominent feature was a left shoulder - mounted blaster . Other assets in the armor ' s design included a system that maintained Prax ' s body temperature in a constant state in any environment . Due to his abilities as a pilot , Prax possessed a personal starfighter for aerial combat . However , his primary vehicle was a Dreadnaught battle tank that was heavily armed with laser cannons , mass - driver cannons , concussion missiles and a plasma pulse discharger . Behind the scenes . Cydon Prax was voiced by André Sogliuzzo in the video game " " . In " " , Prax is described as having a crown of horns and square teeth . No other known Chistori exhibits these traits . Cydon Prax also does not have a large snout like Desann , given that the shape of his helmet reflects a human - like skull .
