During the Clone Wars, Jedi Anakin Skywalker and Ahsoka Tano were ambushed by a pair of IG-86 sentinel droids aboard the Vulture's Claw, while attempting to find their missing astromech droid, R2-D2. Skywalker and Tano failed to retrieve R2-D2, with replacement droid R3-S6—secretly a Separatist spy—claiming that he was not on board after looking at the manifest. However, the ship's owner, scavenger Gha Nachkt, did in fact have the missing droid on board, with the incident making him realize that R2-D2 would clearly be worth something to the Separatists, leading him to offer the droid to General Grievous aboard Skytop Station.
