Mission to the Thicket A mission to the Thicket took place around 21 BBY during the Clone Wars . After helping to liberate the Hutt prisoner Ziro Desilijic Tiure from Republic custody on Coruscant , the sentinel droid - turned - bounty hunter HELIOS - 3D became based in the Thicket , a patch of space over Iego that housed the remains of a previously destroyed Separatist laser system . As the assassin droid ' s amassing army of battle droids began to cause disturbances , the Jedi Order received a request for help , and Jedi Generals Anakin Skywalker and Obi - Wan Kenobi arrived on Iego to investigate the strange happenings . Meeting with Cliffhold resident Jaybo Hood , the Jedi sent a probe droid into the Thicket . However , the recon droid was reprogrammed by HELIOS - 3D and collided with the clone pilot Torrent Four , killing the pilot and sparking an aerial skirmish between Republic fighters and HELIOS - 3D ' s droid forces . The sentinel droid was defeated , and the Jedi searched the droid hunter ' s disabled frigate before departing . However , HELIOS - 3D himself was able to secretly transfer his consciousness into a B1 battle droid . Prelude . Around 21 BBY during the Clone Wars , the bounty hunter Cad Bane formed a team of hunters to free Hutt crime lord Ziro Desilijic Tiure — who had been previously arrested for crimes against the Galactic Republic — from the Republic Judiciary Central Detention Center on the galactic capital of Coruscant . The hunters ' mission was successful , and Bane and his team escaped with Ziro . Shortly thereafter , Bane transmitted the monetary reward for the mission into the accounts of his comrades and then ordered the mercenaries to flee and hide from the Republic . One member of the team , the IG - 86 sentinel droid HELIOS - 3D , became based in the space over the planet Iego and began to form a renegade army of battle droids for his own uses . Named the " Thicket , " the patch of space in which HELIOS - 3D housed his forces was laden with asteroids and the remains of a Separatist LaserWeb Defense Station — once thought to be the workings of Iego ' s mythical god , " Drol " — that had been destroyed earlier in the war by Jedi General Anakin Skywalker and High Jedi General Obi - Wan Kenobi . As HELIOS - 3D caused disturbances in the space over the planet , the Jedi Order received a request for help . With the elusive Cad Bane thwarting the Order ' s attempts to locate him , Jedi Master Yoda assigned Skywalker and Kenobi to investigate the distress call . Meeting with the young Cliffhold resident Jaybo Hood — who had assisted them in destroying the Separatist laser field — in the Cliffhold spaceport city , the Jedi were informed of the unusual activity in the Thicket and set out with Hood to find the source of the disturbances . The mission . Approaching the asteroids of the Thicket in a " Venator " - class Star Destroyer , Skywalker and Kenobi launched a shuttle - mounted probe droid to survey the area ahead . Learning from Hood that several automated drones sent into the Thicket earlier had stopped transmitting , Kenobi ordered Clone Commander CC - 2224 , nicknamed " Cody , " to dispatch manned vessels to monitor the recon droid at a closer range . A pair of V - 19 Torrent starfighters trailed the droid , but the automated scout unexpectedly crashed into clone pilot Torrent Four , eliminating both the pilot and the probe . Enemy Vulture droids advanced toward the Republic ' s fighters and engaged them in combat . Another pilot was lured into the remnants of the Separatist LaserWeb Station and was killed when he flew into a laser . HELIOS - 3D sent more Vulture droid starfighters alongside B2 super battle droids , " Hyena " - class bombers , and " Rogue " - class starfighters to fight the Republic detachment , but a single V - 19 Torrent fighter was able to maneuver through the Thicket ' s asteroids toward the droid force . Engaging the enemy fighters , asteroid - based artillery , and several active " laser rocks , " the pilot defeated HELIOS - 3D ' s forces . Aftermath . Finding HELIOS - 3D ' s disabled " Munificent " - class frigate , Commander Cody was able to reactivate the vessel ' s life support through generators . Skywalker , Kenobi , and Hood boarded the ship and discovered a disabled HELIOS - 3D , and Skywalker salvaged the sentinel droid ' s cranial unit for further study before departing the frigate in the freighter " Twilight " . Unbeknownst to the Republic , however , HELIOS - 3D had transferred his consciousness into a B1 battle droid elsewhere amongst the asteroids . Behind the scenes .
