In 5.5 BBY, IG-88B was tasked with a mission to humiliate Olag Greck by one of Greck’s competitors. The droid stowed aboard a droid barge carrying one of Greck’s spice shipments, but its batteries drained, leaving it in a state of cyberostasis. Discovering the assassin, Greck had IG-88B restrained in carbonite shackles, and put Bardo on guard for the duration of the flight to Hosk Station. Greck planned to give the droid a memory wipe and turn it into his employee, hoping to have it fight to the death as part of a spectacle in the Hosk Arena. However, IG-88B awoke during the flight, and broke out of his restraints while Bardo was distracted by the bickering of fellow passengers C-3PO and R2-D2. Having utilized a program trap to boost his servomotors, IG-88B began tearing the ship apart, causing Bardo and the droids to flee into Hangar Three aboard the station. The GamorreanXob shot the droid as it emerged from the barge, causing the area to be locked down. IG-88B blasted Xob in return, and corralled R2-D2 into giving him access to the rest of the station.
Pausing in an alleyway, IG-88B forced the astromech to repair his blaster damage while Greck searched the station for the assassin. Disguising himself with a hooded cloak, IG-88B made for a shuttle to Kalarba City, but he and Artoo were discovered by C-3PO and Greck’s team. A firefight ensued, and IG-88B was briefly trapped when Xob fired a carbonite constrictor net, pinning him against a wall. Greck taunted the droid, who dropped a smoke grenade and fled with Artoo into the shuttle access tube. IG-88B boarded the shuttle, bringing C-3PO along as well, and blasted out of Hosk Station, pursued by Greck’s cruiser. The droid made for the moon of Indobok, and gave Greck the slip in the canyons. He blasted a rocky archway down onto the cruiser, although stray rubble clipped the shuttle, causing Artoo and Threepio to tumble into the onboard escape pod. Artoo launched out of the shuttle just as IG-88B jumped into hyperspace. The droid’s mission was complete, and Greck deduced that IG-88B had simply been tasked with humiliating him, rather than killing him.
