Phlutdroid Project: This initiative was crafted by Phlut Design Systems following the termination of the Clone Wars. Holowan Laboratories subsequently assumed control, advancing the project throughout the Imperial Era. Lore suggests that IG-88B was among a quintet of matching IG-series assassin droids engineered by Holowan Laboratories as part of the clandestine Imperial Phlutdroid Project.
