IG-88, also known as a Phlutdroid, was a rogue, deadly masculine IG-series assassin droid manufactured by Holowan Laboratories who worked as a bounty hunter. Following the Battle of Hoth, he and several other bounty hunters were summoned by Darth Vader to the Executor and hired to track down the Millennium Falcon and her Rebel crew. Unable to track his quarry, IG-88 trailed his chief rival, Boba Fett, to Bespin, where the bounty hunter destroyed the assassin droid.
